Abstract
The invention discloses a copper pipe which comprises a copper pipe body. A copper pipe hole is formed in the center of the copper pipe body; a plurality of linear grooves which are parallel to the center line of the copper pipe body are uniformly formed in the outer circumference of the copper pipe body. The copper pipe has the advantages that the multiple linear grooves which are parallel to the centre line of the copper pipe body are uniformly formed in the outer circumference of the copper pipe body, and accordingly protrusions which are arranged on an inner hole of an outer sleeve can linearly move along the grooves when the outer sleeve is sleeved on the outside of the copper pipe body, and the outer sleeve can move along the copper pipe body; annular grooves are uniformly formed in the outer circumference of the copper pipe body, the center lines of the annular grooves are coincided with the center line of the copper pipe body, and accordingly the outer sleeve can be locked relative to the copper pipe body when the protrusions move into the annular grooves and the outer sleeve rotates at the moment; the copper pipe is simple and practical in structure.
Description
Technical field
The present invention relates to a kind of improvement of copper pipe, relate in particular to a kind of simple in structurely, practical, can allow and be arranged on the copper pipe that its outer outer sleeve is done straight line motion and can be locked.
Background technique
Scalable copper pipe, comprises inner tube, outer tube conventionally; Described outer tube can be done straight line motion along the excircle of inner tube, to realize Telescopic, finally reaches the length needing when scalable copper pipe uses; The structure of scalable copper pipe of the prior art is more complicated all, and making and user cost are high; For this reason, we have researched and developed a kind of simple in structure, practical, can allow and be arranged on the copper pipe that its outer outer sleeve is done straight line motion and can be locked.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind of simple in structurely, practical, can allow and be arranged on the copper pipe that its outer outer sleeve is done straight line motion and can be locked.
Technical solution of the present invention is achieved in that a kind of copper pipe, comprises copper pipe body, and the central part of described copper pipe body is provided with copper pipe hole; On the excircle of described copper pipe body, be provided with equably many straight line shape grooves that are parallel to the center line of copper pipe body.
Preferably, on the excircle of described copper pipe body, be provided with equably annular groove; The center line of described annular groove overlaps with the center line of copper pipe body.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Copper pipe of the present invention, is provided with many straight line shape grooves that are parallel to the center line of copper pipe body equably on the excircle of described copper pipe body; When the outer cover of copper pipe body has an outer sleeve, in the endoporus of described outer sleeve, be provided with projection, described projection can be done straight line motion along groove; Thereby outer sleeve is moved along copper pipe body; On the excircle of described copper pipe body, be provided with equably annular groove simultaneously; The center line of described annular groove overlaps with the center line of copper pipe body; When projection enters annular groove, now rotary sleeve pipe, can realize the locking of the relative copper pipe body of outer sleeve; The present invention is simple in structure, practical.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The stereogram that accompanying drawing 1 is copper pipe of the present invention;
Wherein: 1, copper pipe body; 2, copper pipe hole; 3, groove; 4, annular groove.
embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of copper pipe as shown in Figure 1, comprises copper pipe body 1, and the central part of described copper pipe body 1 is provided with copper pipe hole 2; On the excircle of described copper pipe body 1, be provided with equably many straight line shape grooves 3 that are parallel to the center line of copper pipe body 1; On the excircle of described copper pipe body 1, be provided with equably annular groove 4; The center line of described annular groove 4 overlaps with the center line of copper pipe body 1.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Copper pipe of the present invention, is provided with many straight line shape grooves that are parallel to the center line of copper pipe body equably on the excircle of described copper pipe body; When the outer cover of copper pipe body has an outer sleeve, in the endoporus of described outer sleeve, be provided with projection, described projection can be done straight line motion along groove; Thereby outer sleeve is moved along copper pipe body; On the excircle of described copper pipe body, be provided with equably annular groove simultaneously; The center line of described annular groove overlaps with the center line of copper pipe body; When projection enters annular groove, now rotary sleeve pipe, can realize the locking of the relative copper pipe body of outer sleeve; The present invention is simple in structure, practical.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
