Description
Technical field
The utility model relates to a kind of double-section standpipe safety caging device, specifically, is a kind of double-section standpipe safety caging device for folding bicycle.
Background technology
Existing folding bicycle, vertical tube is in order to regulate length, all be made binodal, existing double-section standpipe safety caging device, comprise bunching ring joint vertical tube, lower joint vertical tube, locking saving vertical tube and lower joint vertical tube, a through hole is bored in lower joint vertical tube end, the in-built stop nut of through hole, and bunching ring is screwed into stop nut by screw and lower joint vertical tube is fastening.Save vertical tube lower end on adjustable and be carved with catch siding, but some customers do not note, be adjusted to catch siding outer still in use, cause certain potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is, provides the double-section standpipe safety caging device for folding bicycle that a kind of structure is simple, easy and safe to operate.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of double-section standpipe safety caging device, comprise joint vertical tube, lower joint vertical tube, locking saves the bunching ring of vertical tube and lower joint vertical tube, a through hole is bored in lower joint vertical tube end, the in-built stop nut of through hole, bunching ring is screwed into stop nut by screw and lower joint vertical tube is fastening, when catch siding position adjusted to by upper joint vertical tube, lower joint vertical tube outer wall below the position corresponding to stop nut arranges an elasticity boss, when making joint vertical tube adjust to catch siding position, stop nut blocks elasticity boss, upper joint vertical tube can not up pull again.
Described lower joint vertical tube is provided with through hole, the top of elasticity boss is through through hole, the tail end being positioned at the elasticity boss of lower joint vertical tube inboard is provided with the stopper that restriction elasticity boss passes through hole, lower joint vertical tube inboard is provided with spring, spring one end withstands the tail end of elasticity boss, and the other end of spring compresses the inwall of lower joint vertical tube.
The beneficial effects of the utility model are: structure is simple, easy to operate, and safety, the double-section standpipe that can be used for folding bicycle is spacing.
Accompanying drawing explanation
Fig. 1 is the structure cutaway view of the utility model double-section standpipe safety caging device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, double-section standpipe safety caging device of the present utility model, comprise joint vertical tube 6, lower joint vertical tube 1, locking saves the bunching ring 5 of vertical tube 6 and lower joint vertical tube 1, a through hole 2 is bored in lower joint vertical tube 1 end, the in-built stop nut 3 of through hole 2, it is fastening with lower joint vertical tube 1 that bunching ring 5 is screwed into stop nut 3 by screw 4, when catch siding 7 position adjusted to by upper joint vertical tube 6, lower joint vertical tube 1 outer wall below the position corresponding to stop nut 3 arranges an elasticity boss 8, when making joint vertical tube 6 adjust to catch siding 7 position, stop nut 3 blocks elasticity boss 8, upper joint vertical tube 6 can not up pull again.
Specifically, described lower joint vertical tube 1 is provided with through hole, the top of elasticity boss 8 is through through hole, the tail end being positioned at the elasticity boss of lower joint vertical tube 1 inboard is provided with the stopper 11 that restriction elasticity boss passes through hole, lower joint vertical tube 1 inboard is provided with spring, the tail end of elasticity boss 8 is withstood in spring 9 one end, and the other end of spring 9 compresses the inwall of lower joint vertical tube 1.
When catch siding position adjusted to by upper joint vertical tube 67, stop nut 3 blocks elasticity boss 8, and upper joint vertical tube 6 can not pull again, thus ensure that use safety.
Above-described embodiment is only for illustration of technological thought of the present utility model and feature, its object is to enable those skilled in the art understand content of the present utility model and implement according to this, only can not limit the scope of the claims of the present utility model with the present embodiment, namely the equal change that the spirit that all the utility model disclose is done or modification, still drop in the scope of the claims of the present utility model.
