Abstract

The utility model discloses an alarming lamp cover installing structure. The utility model comprises a machine outer casing, a light-passing lamp cover, a circuit board installed with an illuminator and a light-passing pressing block, the machine outer casing has an opening, the lamp cover has a base body, an elastic clipping buckle with a bulging base body surface and a collecting groove formed between the base body and the elastic clipping buckle, the lamp cover is penetrated in the opening and the elastic clipping buckle is used to buckle the machine casing body, the circuit board is fixed on the machine casing body, the pressing block is installed in the collecting groove of the lamp cover, the pressing block has an upper surface and a lower surface, a groove is arranged on the upper surface, the circuit board is used to press the upper surface of the pressing block, the illuminator is extended in the groove, and the lower surface of the pressing block is used to press the lamp cover base body. Because the transparent oppressing block presses the lamp cover, to tightly buckle the elastic clipping buckle of the lamp cover on the machine casing body, the elastic clipping buckle is presented to be broken from the opening of the machine casing body because of distortion, and the reliable fixing of the lamp body can be realized.

Description

The alarm lamp hood mounting structure

Technical field

The utility model is the mounting structure about a kind of lampshade of reporting to the police.

Background technology

See also Fig. 1, the alarm lamp hood mounting structure of existing Medical Devices comprises lampshade 1, machine case 2 and has the circuit board 3 of illuminator.This lampshade 1 is to make for the hard transparent PC material of 1-2mm with average meat is thick, and two Elastic buckles 11 that its utilization directly grows are clasped with the wall 22 of machine case 2 opening parts, and 3 of circuit boards are installed in by screw on the erection column 21 of machine case 2.In order to increase refraction to reach certain effect of dispersing, this lampshade generally increases lines or lampshade is made milky in the back die face.But this lampshade mounting structure has following shortcoming: 1) lampshade is fixing unreliable, installs afterwards even can free-hand from the outside it be pulled down; 2) brightness is low, inhomogeneous and can see luminous point, can not play the effect of significantly reporting to the police preferably.

Summary of the invention

Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, provides a kind of lampshade to fix reliable alarm lamp hood mounting structure.

The technical solution adopted for the present invention to solve the technical problems is: this alarm lamp hood mounting structure comprises machine casing, transparent lamp shade, the circuit board and the printing opacity briquetting of illuminator are housed, this machine casing has opening, this lampshade has matrix, protrude the Elastic buckle of matrix surface and be formed at accepting groove between this matrix and the Elastic buckle, this lampshade penetrates this opening and its Elastic buckle fastens this machine case, this circuit board is fixed on this machine case, pack into the accepting groove of lampshade of this briquetting, this briquetting has upper surface and lower surface, this upper surface is provided with groove, this circuit board is pushed down the upper surface of briquetting, this illuminator stretches into this groove, and the lower surface of this briquetting is pushed down the lampshade matrix.

The edge of described machine casing opening convexes with wall, and the Elastic buckle of lampshade fastens this wall.

Described briquetting is the silica gel piece.Described illuminator is that paster is emitting led.

The invention has the beneficial effects as follows,, the Elastic buckle of lampshade is held on the machine case, thereby can prevent that Elastic buckle from deviating from the opening of machine case because of distortion, realize the secure fixation of lampshade because transparent briquetting pushes down lampshade.

The specific embodiment

See also Fig. 2 and Fig. 3, the utility model alarm lamp hood mounting structure comprises machine case 4, transparent lamp shade 5, printing opacity briquetting 6 and the circuit board 7 of paster emitting led 8 is housed.This machine case 4 has the opening 41 that is used to install lampshade, and the edge of this opening 41 convexes with two walls 42, and is equipped with the erection column 43 with screwed hole in the outside of these two walls 42.This transparent lamp shade 5 is made for the hard transparent PC material of 1-2mm by average meat is thick, this lampshade 5 comprises matrix 51 and two cantilever-shaped Elastic buckles 52 that protrude out from these matrix 51 surfaces, these two Elastic buckles 52 separate be provided with and and matrix 51 between form accepting groove 53.This printing opacity briquetting 6 has upper surface 61 and lower surface 62, and this upper surface 61 is provided with groove 63.This briquetting 6 is as silica gel piece 6, and this silica gel piece 6 has the silica gel material of better light transmission and diversity to make by certain thickness furnishing is milky.

During installation, lampshade 5 is penetrated the opening 41 of machine case from the bottom to top, make the Elastic buckle 52 of lampshade fasten the wall 42 of machine case, lampshade 5 is installed on the machine casing 4; Then, utilize strain silica gel piece 6 to be clamp-oned in the accepting groove 53 of lampshade, the lower surface 62 of silica gel piece was pushed down the matrix 51 of lampshade and was not allowed Elastic buckle 52 distortion of lampshade deviate from this moment; At last, will be equipped with on the erection column 43 that the emitting led circuit board of paster 7 is fixed on machine casing with screw 9, paster emitting led 8 stretches into the groove 63 of silica gel piece, and this circuit board 7 is pushed down the upper surface 61 of silica gel piece.

In the utility model, utilize the silica gel piece that lampshade is withstood and make Elastic buckle can not be out of shape the opening of deviating from machine case, can not free-hand from the outside lampshade be pulled down.Because the silica gel piece has light transmission and diversity preferably, the lampshade appearance tactile impression that the PC material is made better and be not easy to make dirty, there is the effect of more significantly reporting to the police in institute so that lampshade is luminous bright, evenly and can not see luminous point.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
