Description

A kind of bicycle saddle tube assembly with theft-prevention structure

Technical field

The utility model relates to a kind of bicycle saddle tube, particularly with the bicycle saddle tube assembly of theft-prevention structure.

Background technology

Bicycle saddle tube is common bicycle accessories.Existing portable bicycle, for convenience of the demand of riding of different height, after desired height is transferred to by usual seat pipe, then locks with the beam ring of the eccentric quick detach of band.

But the seat pipe of existing structure locking, because structure is simple, easily dismantles, so also just easily stolen.

Utility model content

Technical problem to be solved in the utility model is, provides a kind of structure simple, the lower-cost bicycle saddle tube assembly with theft-prevention structure.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bicycle saddle tube assembly with theft-prevention structure, comprise in bicycle and managing, bicycle saddle tube and the tight ring of saddle tube bundle, in bicycle, pipe is two sections of anisodiametric pipes, in bicycle, pipe epimere diameter is little, in bicycle, pipe hypomere diameter is large, the tight ring of saddle tube bundle is connected in outside the upper end of pipe epimere in bicycle, in the bicycle of pipe epimere in bicycle, pipe hypomere tube wall has a through hole, bicycle saddle tube lower end sidewall is provided with a tapped bore, screw is screwed into the tapped bore of bicycle saddle tube through through hole, bicycle saddle tube and screw can be moved in pipe hypomere in bicycle, in bicycle, pipe epimere place is then blocked by screw, bicycle saddle tube can not be removed.

The beneficial effects of the utility model are: be screwed into a screw by present pipe bottom.Make to block when a pipe moves more carefully to locate at middle pipe, effectively can solve the antitheft problem of the bunching ring locking bicycle saddle tube of the eccentric quick detach of existing band.

Accompanying drawing explanation

Fig. 1 is the structure cutaway view of the utility model with the bicycle saddle tube assembly of theft-prevention structure.

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, bicycle saddle tube assembly with theft-prevention structure of the present utility model, comprise pipe 1 in bicycle, bicycle saddle tube 2 and the tight ring 3 of saddle tube bundle, in bicycle, pipe 1 is two sections of anisodiametric pipes, in bicycle, pipe epimere 1a diameter is little, in bicycle, pipe hypomere 1b diameter is large, the tight ring 3 of saddle tube bundle is connected in outside the upper end of pipe epimere 1a in bicycle, in the bicycle of pipe epimere 1a in bicycle, pipe hypomere 1b tube wall has a through hole 5, bicycle saddle tube 2 lower end sidewall is provided with a tapped bore 4, screw 6 is screwed into the tapped bore 4 of bicycle saddle tube through through hole 5, bicycle saddle tube 2 and screw 6 can be moved in pipe hypomere 1b in bicycle, in bicycle, pipe epimere 1a place is then blocked by screw 6, bicycle saddle tube 2 can not be removed.

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.
