Description

Can antitheft seat pipe quick-disassembly structure

Technical field

The utility model relates to the anti-theft technique of two-wheel car, refers to a kind of theft-prevention structure that is applicable to seat pipe quick detach especially.

Background technology

Common two-wheel car, for example bicycle is gone out sometimes by bike, gets off for some reason to leave and park the roadside, returns when desiring to drive bicycle, finds that but seat cushion disappears.

Because the structure of bicycle, as shown in Figure 1, a vehicle frame 10 connects a pipe 11, and a clamp ring 12 is installed on the mouth of pipe, and assembles a quick detach 13 at clamp ring 12 two ends.This pipe 11 inserts for the seat cushion bar 16 of a connecting seat pad 15, pulls 12 pairs of seat cushion bars 16 of fast dismounting handle 14 drive clamp rings and is seized on both sides by the arms the location.

So, fast dismounting handle 14 has no the safety apparatus of any protection, as long as push fast dismounting handle 14 aside, just can remove the usefulness of seizing on both sides by the arms that clamp ring 12 is bestowed seat cushion bar 16, easily steals seat cushion 15.

Though be not how expensive thing, lack seat cushion, be unfavorable for driving of bicycle, increase rider's puzzlement on foot.

In view of this, the inventor deeply inquires into the problem of prior art, and research and development and manufacturing experience to be engaged in related industry for many years, actively seeks solution, successfully develop finally a kind of can be theft-proof seat pipe quick-disassembly structure, commonly use the problem of creation with improvement.

The utility model content

The purpose of this utility model is to provide a kind of can manage quick-disassembly structure by theft-proof seat, adopts the means that lock, and the protection seat cushion avoids stealing, and strengthens the anti-theft feature of bicycle.

For reaching above-mentioned purpose, the technical solution of the utility model is such:

A kind of can be antitheft seat pipe quick-disassembly structure, be assembling one quick detach on a pipe, this quick detach has the fast dismounting handle that can pull; Wherein this fast dismounting handle is provided with a breach, and the lock ring of an outstanding pipe passes breach and keyed one safety member.

This lock ring forms in a clamp ring outside that present pipe is installed, and the fast dismounting handle breach that is assembled in the clamp ring opening by quick detach pins safety member.

This safety member is a padlock.

This safety member is the tapered end of an outfit rope, chain.

Adopt said structure, the utility model utilizes padlock or is equipped with the tapered end of rope, chain, pinned lock ring by the fast dismounting handle breach, reach the purpose that reduces the stolen probability of seat cushion, and aforementioned tapered end can also entangle the surrounding object product with rope, chain, for example trees, electric pole, jiffy stand, billboard or Lou Zhu etc. except pinning by the lock ring of fast dismounting handle breach, reduce the stolen probability of seat cushion, strengthen the anti-theft feature of bicycle simultaneously.
