For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of telescopic pipe external member, comprise interior pipe, outer tube, inner sleeve, slide block and lock dog, the tube wall of described interior pipe is provided with multiple locating slot, described inner sleeve is set on described interior pipe, described outer tube sleeve be located at described in put, one end of described lock dog is stretched in described locating slot through described inner sleeve, the other end of described lock dog and the contact internal walls of described slide block, described slide block be pressed in described in put, the inwall of described slide block is provided with groove, two-part up and down of described slide block are lived by semicircular upper cover and lower cover inclusion respectively, described upper cover and lower cover are fastened togather with described slide block respectively, the inwall at described upper cover and lower cover two ends is provided with spring, one end of described spring props up the inwall of the end of described slide block.
In the utility model preferred embodiment, the shape of described locating slot and the matching form of described lock dog end.
The beneficial effects of the utility model are: telescopic pipe external member telescopic pipe external member of the present utility model is coordinated with the locating slot on pipe fitting by lock dog, and can realize the flexible of pipe fitting, easy to operate, fixation after telescopic pipeline, not easily throws off.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the detonation configuration schematic diagram of telescopic pipe external member of the present utility model;
Fig. 2 is the vertical magnification structural representation sectional view at upper cover in Fig. 1 and lower cover place.
In accompanying drawing, the mark of each parts is as follows: 1, interior pipe, and 2, outer tube, 3, inner sleeve, 4, spring, 5, slide block, 6, lock dog, 7, upper cover, 8, lower cover, 9, groove, 10, locating slot.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model is embodiment comprise:
A kind of telescopic pipe external member, comprise interior pipe 1, outer tube 2, inner sleeve 3, slide block 5 and lock dog 6, the tube wall of described interior pipe 1 is provided with multiple locating slot 10, described inner sleeve 3 is set on described interior pipe 1, described outer tube 2 is set in described inner sleeve 3, one end of described lock dog 6 is stretched in described locating slot 10 through inner sleeve 3, the other end of described lock dog 6 and the contact internal walls of described slide block 5, described slide block 5 is pressed in described inner sleeve 3, the inwall of described slide block 5 is provided with groove 9, shape and the lock dog 6 of groove 9 match, and dodge space for lock dog 6 provides.Two-part up and down of described slide block 5 are lived by semicircular upper cover 7 and lower cover 8 inclusion respectively, described upper cover 7 and lower cover 8 are fastened togather with described slide block 5 respectively, the inwall at described upper cover 7 and lower cover 8 two ends is provided with spring 4, and one end of described spring 4 props up the end of described slide block 5.
Preferably, the shape of described locating slot 10 and the matching form of described lock dog 6 end.
Further, grasp upper cover 7 and lower cover 8, interior pipe 1 pulls out by another hand simultaneously, and spring 4 is compressed, and slide block 5 acts on lower slider at spring 4, no longer pushes down lock dog 6, locating slot 10 can be left in one end of lock dog 6, the other end of lock dog 6 moves up and enters in the groove 9 of slide block 5, and lock dog 6 is unlocked, and now, pipe 1 can relatively pull out or push by outer tube 2, realize the Telescopic of pipe fitting, change the length of pipe fitting.
When upper cover 7 and the lower cover 8 of coming loose, lock dog 6 is pushed locating slot 10 by the pressure retrogressing that slide block 5 is subject to spring 4, slide block 5 is pushed down lock dog 6 in the effect lower slider of spring 4 to lock dog 6 place lock dog 6 can not be upspring, and in realizing, pipe 1 and inner sleeve 3 lock, interior pipe 1, outer tube 2 and inner sleeve 3 fixation.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
