Abstract
The utility model discloses a kind of expansion bent, comprise: bend pipe, inner sleeve, slip lid and lock dog, the tube wall of described bend pipe is provided with multiple locating slot, described inner sleeve is set on described bend pipe, the stopper being provided with protrusion is put in described, one end of described lock dog is stretched in described locating slot through the wall of described inner sleeve, the other end of described lock dog and the contact internal walls of described slip lid, the inwall of described slip lid is provided with groove, be provided with spring in described groove, one end of described spring props up described stopper.Expansion bent of the present utility model can realize the flexible, easy to operate of bend pipe easily, and fixation after bend pipe is flexible, not easily throw off, grip feeling is comfortable.
Description
Technical field
The utility model relates to a kind of expansion bent.
Background technology
In dust catcher and some cleaning supplies, telescopic bend pipe can be used.Some current expansion bent complex structures, operation inconvenience.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of expansion bent, and this expansion bent can realize the flexible, easy to operate of bend pipe easily, and fixation after bend pipe is flexible, not easily throws off.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of expansion bent, comprise bend pipe, inner sleeve, slip lid and lock dog, the tube wall of described bend pipe is provided with multiple locating slot, described inner sleeve is set on described bend pipe, the stopper being provided with protrusion is put in described, one end of described lock dog is stretched in described locating slot through the wall of described inner sleeve, the other end of described lock dog and the contact internal walls of described slip lid, the inwall of described slip lid is provided with groove, spring is provided with in described groove, one end of described spring props up described stopper.
In the utility model preferred embodiment, the side of described lock dog is close to described stopper.
In the utility model preferred embodiment, the radius of curvature of the central axis of described bend pipe is 900-2000mm.
The beneficial effects of the utility model are: expansion bent of the present utility model is coordinated with the locating slot on bend pipe by lock dog, can realize the flexible, easy to operate of bend pipe, and fixation after bend pipe is flexible, not easily throw off, and the grip feeling held is comfortable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical 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 expansion bent of the present utility model;
Fig. 2 is the structural representation top view of expansion bent of the present utility model;
Fig. 3 is the structure for amplifying schematic diagram sectional view of expansion bent of the present utility model.
In accompanying drawing, the mark of each parts is as follows: 1, bend pipe, and 2, inner sleeve, 3, spring, 4, slip lid, 5, lock dog, 6, locating slot, 7, groove, 8, stopper.
Detailed description of the invention
Be clearly and completely described to the technical 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 to Fig. 3, the utility model embodiment comprises:
A kind of expansion bent, comprise bend pipe 1, inner sleeve 2, slip lid 4 and lock dog 5, the tube wall of described bend pipe 1 is provided with multiple locating slot 6, described inner sleeve 2 is set on described bend pipe 1, described inner sleeve 2 is provided with the stopper 8 of protrusion, one end of described lock dog 5 is stretched in described locating slot 6 through the wall of described inner sleeve 2, the other end of described lock dog 5 and the contact internal walls of described slip lid 4, the inwall of described slip lid 4 is provided with groove 7, be provided with spring 3 in described groove 7, one end of described spring 3 props up described stopper 8.
Preferably, the side of described lock dog 5 is close to described stopper 8.
The radius of curvature of the central axis of described bend pipe is 900-2000mm, and the bend pipe of this degree of crook is very comfortable by the grip feeling held up.This radius of curvature is preferably 1500mm the best.
Further, grasp inner sleeve 2, thumb promotes slip lid 4 simultaneously, spring 3 is compressed, and slip lid 4 no longer pushes down lock dog 5, and lock dog 5 can leave locating slot 6 and move up and enter in groove 7, lock dog 5 is unlocked, and now can pull out or push bend pipe 1, realizes the relative telescopic function of bend pipe 1 and inner sleeve 2.
When the slip lid 4 that comes loose, its pressure being subject to spring 3 retreats and lock dog 5 is pushed locating slot 6, and slip lid 4 moves right and pushes down lock dog 5 under the effect of spring 3, and bend pipe 1 and inner sleeve 2 lock.
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.
