Abstract
The utility model discloses a bicycle seat tube assembly with an anti-theft structure. The bicycle seat tube assembly with the anti-theft structure comprises a seat tube, a fixed seat, a connecting sheet and a bolt, wherein the fixed seat is positioned on the upper end of the seat tube; the connecting sheet is positioned on the lower end of the seat tube; the fixed seat and the connecting sheet are connected by the bolt; the fixed seat is provided with a through hole through which the screw of the bolt passes; the diameter of the through hole is slightly bigger than the external diameter of the screw; the fixed seat is arranged on the upper end of the seat tube; the connecting sheet of which the diameter is not bigger than the external diameter of the seat tube is arranged on the bottom end of the seat tube; the connecting sheet is eccentrically provided with a screw hole with an internal thread and a positioning boss near the inner wall of the seat tube in the seat tube; and the screw of the bolt passes through the fixed seat to be connected with the eccentric thread of the screw hole of the connecting sheet on the bottom of the seat tube. According to the bicycle seat tube assembly with the anti-theft structure, which is disclosed by the utility model, the seat tube with an eccentric sheet is clamped with a bicycle frame middle tube, the seat tube can be taken out of the middle tube only with a tool, and therefore the anti-theft problem of the seat post of the traditional locking bicycle with an eccentric quickly-detached clamping ring is effectively solved.
Description
Technical field
The utility model relates to a kind of bicycle saddle tube, particularly with the clamp ring with eccentric quick detach, locks the theft-prevention structure of bicycle saddle tube.
Background technology
Bicycle seat pole is common bicycle accessories.Existing portable bicycle, for convenience of the demand of riding of different heights, seat pipe is transferred to after desired height conventionally, then locks with the clamp ring with eccentric quick detach.
But, the seat pipe of existing structure locking, due to simple in structure, easily dismounting, so also just easily stolen.
Utility model content
Technical problem to be solved in the utility model is provide a kind of use with the seat pipe of the clamp ring locking of eccentric quick detach but be difficult for stolen.
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, comprises a bolt of managing, be positioned at the permanent seat of Zuo Guan upper end, the connecting strap that is positioned at Zuo Guan lower end and connection fixing base and connecting strap; On permanent seat, be provided with the through hole that the screw rod of bolt is passed, through hole is more bigger than the external diameter of the screw rod of bolt, and permanent seat rides over Zuo Guan upper end; The connecting strap that diameter is not more than seat pipe external diameter arranges present Guan bottom, eccentric being provided with female screw and the positioning convex near seat inside pipe wall that is positioned at a pipe on connecting strap, the bias that the screw rod of bolt is managed the screw of bottom connecting strap through permanent seat and seat is threaded.
The screw rod lower end of described bolt is also provided with for preventing the nut of connecting strap landing.
The beneficial effects of the utility model are: by bolt in instrument rotary fixing base, drive connecting strap to rotate around screw rod line of centers, and move up along screw rod, when connecting strap eccentric throw increases, when connecting strap outside and the outer lateral extent of other end seat pipe are greater than in vehicle frame bore, just can make with pipe clamp in the seat pipe of Cam plate and vehicle frame.Useful tool is therefrom taken out seat pipe in pipe.This structure can effectively solve the antitheft problem of the clamp ring locking bicycle seat pole of the eccentric quick detach of existing band.

Fig. 2 is that the utility model is used view.
Fig. 3 is that the utility model is used view partial enlarged drawing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, 2, 3, the bicycle saddle tube assembly with theft-prevention structure of the present utility model, comprises seat pipe 1, is positioned at the bolt 3 of a permanent seat 2 for seat pipe 1 upper end, the connecting strap 4 that is positioned at seat pipe 1 lower end and connection fixing base 2 and connecting strap 4; On permanent seat 2, be provided with the through hole 9 that the screw rod of bolt 3 is passed, through hole 9 is more bigger than the external diameter of the screw rod of bolt, and permanent seat 2 rides over a upper end for seat pipe 1; Diameter is not more than seat and manages the bottom that the connecting strap 4 of 1 external diameter arranges present pipe 1, eccentric being provided with female screw and the positioning convex 6 near seat inside pipe wall 7 that is positioned at a pipe on connecting strap 4, the bias that the screw rod of bolt 3 is managed the screw of 1 bottom connecting strap 4 through permanent seat 2 with seat is threaded.
The screw rod lower end of described bolt 3 is also provided with for preventing the nut 5 of connecting strap 4 landings.
During installation, with in instrument rotary fixing base 2 during bolt 3, when R1+R2 >=D1 (R1=seat pipe radius, R2=connecting strap eccentric throw d+ connecting strap radius R 3, manages interior diameter in D1), just can make to manage 8 clampings in seat pipe 1 and vehicle frame.
Above-described embodiment is only for illustrating technological thought of the present utility model and feature, its object is to make those skilled in the art can understand content of the present utility model and implement according to this, can not only with the present embodiment, limit the scope of the claims of the present utility model, be equal variation or the modification that spirit that all the utility model disclose is done, still drop in the scope of the claims of the present utility model.
