Description

But but the tripod of fixed angle reflexed

[technical field]

The utility model relates to a kind of photographic goods, refers in particular to used tripod on camera frame or the hand-held shooting stabilizator.

[background technology]

Along with the development of science and technology and shifting to an earlier date of people's living standard, the application of video camera and camera is also more and more universal.Present stage, people make a video recording with video camera or camera, when taking a picture since in shooting process, rock or jitter phenomenon more serious, thereby cause photographic effect or image quality not good, so people have invented camera frame and hand-held shooting stabilizator.Present stage, camera frame all can be used tripod and play a supporting role.Because conventional tripod do not have the fixed angle function, so that hand-held shooting stabilizator is used tripod structure is then fewer.Current tripod structure more complicated, cause production cost high, conventional foot rest only has the one direction location, can change in the angle of making time spent certain or some pin wherein that is subject to external force or pin pipe self gravitation, thereby affect shooting effect, even can cause whole camera frame and hand-held shooting stabilizator to lose steadily, so the tripod of current apparatus for making a video recording less stable in use.

[utility model content]

The purpose of this utility model is to overcome the deficiencies in the prior art, but but provides a kind of rational in infrastructure, tripod of using fixed angle reflexed stable and easy to carry.

In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals:

But but a kind of fixed angle reflexed tripod, it includes the trident board and is rotatably connected on feet in the U-shaped short slot of each bifurcated of trident board by bearing pin, above short slot, be provided with to prevent the block of the feet forward folding of deployed condition, in the center pit of trident board, be provided with threaded rod, have in the lower square set of this threaded rod and can keep off simultaneously at the triangle limited location fork of three feet front end bottom surfaces that are in deployed condition and be screwed with to lock the set nut of limited location fork; Described limited location fork is corresponding with the trident board in shape, and the perpendicular wall of its outer most edge just with above the feet front end that is in reverse folding state contacts.

But but in the improvement project to the tripod of above-mentioned fixed angle reflexed, be screwed with foot pad in described feet ground terminal.

But but in the improvement project to the tripod of above-mentioned fixed angle reflexed, be screwed with the counterweight counterweight in described feet ground terminal.

But but in the improvement project to the tripod of above-mentioned fixed angle reflexed, in the internal thread hole of described threaded rod lower end, be screwed with and prevent the back-out screw of threaded rod of set nut.

Compared with prior art, the beneficial effects of the utility model are: it is to utilize the triangle limited location fork corresponding with the trident board and set nut to control three feets could rotate folding, and locked by set nut again after living the top of feet and limited the bottom surface of feet by the rib of limited location fork by the stop limits on each bifurcated of trident board, feet can not be rotated around bearing pin, thereby avoid the feet under the deployed condition to cause under external force expanded angle to change even the forward folding, thereby guarantee shooting effect and keep the steady of whole camera frame or hand-held shooting stabilizator, it is of the present utility model relatively simple for structure reasonable to find out; And not with the time remove reverse folding feet after feet spacing by unscrewing set nut and turn limited location fork, thereby be convenient to daily carrying.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

[embodiment]

But but the utility model is a kind of tripod of fixed angle reflexed, as shown in Figures 1 to 3, the trident board 2 that it includes, and be rotatably connected on feet 3 in the U-shaped short slot 211 of each bifurcated 21 of trident board 2 by bearing pin 20, above short slot 211, be provided with to prevent the block 212 of the feet 3 forward foldings of deployed condition, in the center pit of trident board 2, be provided with threaded rod 4, have in the lower square set of this threaded rod 4 and can keep off simultaneously at the triangle limited location fork 5 of three feets, the 3 front end bottom surfaces 31 that are in deployed condition and be screwed with to lock the set nut 6 of limited location fork 5; At this, be that rib 51 by described limited location fork 5 tops just keeps off the feet 3 reverse foldings after feet 3 front end bottom surfaces 31 prevent from launching; Described limited location fork 5 is corresponding with trident board 2 in shape, and the perpendicular wall 52 of its outer most edge just with 32 contact above feet 3 front ends that are in reverse folding state.

The utility model is when launching to use, limited location fork 5 be installed in trident board 2 under, as shown in Figures 1 to 3, at this moment the front end bottom surface 31 of feet 3 and top 32 is just limited by the rib 51 of limited location fork 5, block 212 and the set nut 6 of bifurcated 21, makes up oppositely folding or the down forward folding of whole feet 3; And do not using need to be with the reverse folding of back-up block the time, after unscrewing first locking locknut 6 feet 3 is avoided in limited location fork 5 rotations, as shown in Figure 4, what at this moment feet just can not touch limited location fork 5 when rotating dodges limit 53, so just can up rotate folding feet 3, tighten set nut 6 after after reflexed is finished limited location fork 5 being rotated under the trident board, at this moment 32 just blocked by the perpendicular wall 52 of the outer most edge of limited location fork 5 and can't launch above 3 front ends of the feet behind the reflexed, as shown in Figs. 5 to 7.

The utility model is to utilize the triangle limited location fork 5 corresponding with trident board 2 and set nut 6 to control three feets could rotate folding, and by the block 212 on each bifurcated 21 of trident board 2 limit feet 3 top 32 and limited by the rib 51 of limited location fork 5 behind the bottom surface 31 of feet 3 again by set nut 6 lockings, feet can not be rotated around bearing pin 20, thereby avoid the feet under the deployed condition to cause under external force expanded angle to change even the forward folding, thereby guarantee shooting effect and keep the steady of whole camera frame or hand-held shooting stabilizator, it is of the present utility model relatively simple for structure reasonable to find out; And not with the time remove reverse folding feet after feet 3 spacing by unscrewing set nut 6 and turn limited location fork 5, thereby be convenient to daily carrying.

Under normal conditions, when the utility model is used as the tripod of camera frame, shown in Figure 10,11, it is installed in column 1 lower end, and is screwed with foot pad 9 in described feet 3 ground terminals; And when being used as the counter-balanced carriage of hand-held shooting stabilizator, whole tripod also is mounted in column 1 lower end, and be screwed with counterweight counterweight 7 in described feet 3 ground terminals, when counterweight, just can select the counterweight of corresponding weight to come the whole stabilizator of balance according to the difference of camera weight, shown in Fig. 8,9.

In the internal thread hole of described threaded rod 4 lower ends, be screwed with and prevent the back-out screw 8 of threaded rod 4 of set nut 6, also in screw 8, be provided with back-up ring 10 at this.

Feet 3 can be rotatably connected in the short slot of bifurcated by screw or other rotating shaft.

Being the utility model preferred embodiment only in sum, is not to limit practical range of the present utility model, i.e. all equivalences of doing according to the content of the utility model claim change and modify, and all should belong to technology category of the present utility model.
