Embodiment Construction

[0014] combine figure 1 with figure 2 , as described in detail below:

[0015] A seat bar anti-theft mechanism (1), installed between the seat bar 1 and the middle tube 2 of the frame, the seat bar 1 is inserted into the middle tube 2 of the frame, the anti-theft mechanism is a steel cable 3, the steel cable 3 One end forms a limiting portion 31, which passes through the umbrella-shaped washer 4 fixed in the seat rod 1. The umbrella-shaped washer 4 is made of rigid material, and the middle part has a through hole that can pass through the steel cable 3 and the peripheral part has multiple holes. An umbrella-shaped distribution of shrapnel, so that when the umbrella-shaped washer 4 is pressed into the seat rod, the multi-piece umbrella-shaped distribution of shrapnel expands, and is fixed inside the seat rod 1, while the other end of the steel cable 3 A cable ring 32 is formed, and is fixed in the middle tube 2 of the vehicle frame by a bolt 5 passing through the cable ring,...

Abstract

The invention relates to an anti-theft mechanism (I) for a seat cushion rod.. The anti-theft mechanism is mounted between the seat cushion rod and a frame seat tube, the seat cushion rod is inserted into the frame seat tube, the anti-theft mechanism is of a steel rope, one end of the steel rope where a limiting part is formed, penetrates through an umbrella-shaped washer in the seat cushion rod, the umbrella-shaped washer is made of a rigid material, a through hole which can enable the steel rope to penetrate through is arranged at the middle part of the umbrella-shaped washer, a plurality of spring leaves which are distributed like an umbrella are arranged on the periphery of the umbrella-shaped washer, and the other end of the steel rope where a steel rope ring is formed, is fixed in the frame seat tube through a bolt penetrating through the steel rope ring. The anti-theft mechanism disclosed by the invention can not only play the effect of a seat cushion during riding of a rider, but also play an anti-theft role, the appearance can be prevented from being affected, and the anti-theft mechanism further has practical value.

Description

technical field [0001] The invention belongs to an anti-theft mechanism for bicycles, in particular to an anti-theft mechanism for preventing the pull-out of a seat cushion rod on a bicycle. Background technique [0002] As everyone knows, bicycle stepping is a kind of good walking-replacing tool, and is conducive to people's physical exercise, and for the cyclist's individual requirements, each component of bicycle is designed as self-regulation as far as possible, and the seat post on the bicycle is no exception. The upper end of the seat rod is used to fix the seat cushion, while the lower end is used to insert the middle tube of the vehicle frame, after the seat rod is inserted into the middle tube of the vehicle frame, it is fixed by the upper clamping mechanism of the middle tube of the vehicle frame. Then the bicycle that is parked in public place often takes place that the seat bar on the bicycle is pulled out and stolen. How to design a kind of anti-theft mechanism ...
