Abstract

The utility model discloses a kind of antitheft bunching ring for city public bicycle, comprise bunching ring, eccentric handle, with the screw rod of eccentric handle hinge and setting nut, cave in and be formed with a hole larger than diameter of thread in afterbody one end of setting nut, when screw rod put into by setting nut, compress setting nut at the built-in loading hold-down nut of the Kong Zhongzai of setting nut afterbody.Described hold-down nut is the triangle hold-down nut that special tool need be used to dismantle.The utility model utilizes built-in triangle hold-down nut to compress setting nut, makes bunching ring setting nut not easily by easy removal, decreases bunching ring and loses and stolen possibility.

Description

A kind of antitheft bunching ring for city public bicycle
Technical field
The utility model relates to a kind of bunching ring, particularly a kind of antitheft bunching ring for city public bicycle.
Background technology
Existing city public bicycle bicycle, in order to seat pipe telescopic adjustment is convenient, quick detach is tightened in most employing makes pipe in itself and bicycle be fastenedly connected.But tighten quick detach and facilitate adjustment, also result in and easily lose and stolen possibility.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of easy to use, not easily stolen and lose the antitheft bunching ring for city public bicycle.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of antitheft bunching ring for city public bicycle, comprise bunching ring, eccentric handle, with the screw rod of eccentric handle hinge and setting nut, cave in and be formed with a hole larger than diameter of thread in afterbody one end of setting nut, when screw rod put into by setting nut, compress setting nut at the built-in loading hold-down nut of the Kong Zhongzai of setting nut afterbody.
Described hold-down nut is the triangle hold-down nut that special tool need be used to dismantle.
The beneficial effects of the utility model are: utilize built-in triangle hold-down nut to compress setting nut, make bunching ring setting nut not easily by easy removal, decrease bunching ring and lose and stolen possibility.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the antitheft bunching ring of city public bicycle.
Fig. 2 is Figure 1A-A cutaway view.
Fig. 3 is triangle nut schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As Figure 1-3, the utility model is used for the antitheft bunching ring of city public bicycle, comprise bunching ring 1, eccentric handle 2, with the screw rod 3 of eccentric handle 2 hinge and setting nut 4, cave in and be formed with a hole 5 larger than diameter of thread in afterbody one end of setting nut 4, when screw rod 3 put into by setting nut 4, in the hole 5 of setting nut 4 afterbody, built-in loading hold-down nut 6 compresses setting nut 4 again.
Described hold-down nut 6 is the triangle hold-down nut that special tool need be used to dismantle.
Specifically, setting nut 4 afterbody has a hole 5 larger than diameter of thread, setting nut 4 is put into screw rod 3, after quick-detachment locking elasticity is adjusted, reinstall a triangle hold-down nut 6 at setting nut 4 tail hole 5 and compress setting nut 4, thus setting nut 4 cannot exit.Because using triangle hold-down nut that special tool need be used to dismantle bunching ring, maintainer is only had to use special tool to keep in repair and to change.Thus decrease that city public bicycle is outdoor for a long time to be parked, bunching ring easily lose and stolen may.
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.
