Anti-theft device for handlebar machinery

Abstract

The invention discloses an anti-theft device for handlebar machinery. The anti-theft device is characterized in that a stem of the handlebar or a handlebar trailing arm is separated, the two separated parts can be engaged and locked by a legal user, so that the using function and effect of the stem and the handlebar trailing arm which are not separated are achieved, and the stem and the handlebar trailing arm cannot be engaged by an illegal user, so that a bicycle cannot be used. The invention has the advantages that the anti-theft device is simple in structure, reasonable in design, wide in application range, low in cost and high in reliability, thieves difficulty shear, cut and damage the handlebars, and the like. When the bicycle is in an anti-theft state, even if the bicycle is stolen by a thief, the bicycle cannot be used by the thief, and convenience is provided for timely identifying the thief; and when the handlebar is in a suspended abnormal state, the handlebar has striking characteristics, and when stolen and transferred, the handlebar has the function of displaying abnormality, easily attracts attention, can be discovered and has an alarm effect; and therefore, the functions of preventing burglary and displaying an abnormal state are realized.

Description

technical field [0001] The invention relates to an anti-theft device for handlebar machines, which can be widely applied to machines with handlebar devices, including power machines and motorized machines, and is expected to completely solve the anti-theft problem for handlebar machines. Background technique [0002] A large number of representative products in the handlebar machinery are bicycles, electric bicycles and motorcycles, especially bicycles. As we all know, in the 1980s, the number of bicycles in my country exceeded 500 million, and it was called the "Bicycle Kingdom" (according to "Zhejiang Daily" on June 15, 2006). Since the reform and opening up, China has become the largest bicycle production, consumption and export country in the world. The advantage of labor costs has enabled China to concentrate more than 65% of the world's bicycle production capacity in the 1990s (according to "2012-2016 China Bicycle Industry Market Survey and Investment Analysis Report"...

AI Technical Summary

Problems solved by technology

But in fact, no matter how ingenious and difficult the design of the anti-theft lock is, including mechanical, password, fingerprint, infrared anti-theft devices and even remote control with transmitters and other anti-theft measures, car thieves do not have any technical content. Almost all anti-theft locks are useless when cut by powerful clamps

[0006] Among other anti-theft patents related to bicycle handlebars, Chinese patent 201020548861.0 discloses a detachable movable handlebar for bicycles, but its disadvantages are obvious: after the handlebars are removed, the handlebars without handlebars are only shortened but can still be ridden , cannot fundamentally solve the anti-theft problem of bicycles

And Chinese patent 201020129491.7 has announced a kind of device that can be detached bicycle faucet, but it has the following defects: at first be to dismantle bicycle faucet and carry with you, there are many other auxiliary equipments on the bicycle faucet, single consider from its volume and weight , its disadvantage is obviously inconvenient; secondly, there are left and right double brake connecting cables, variable speed connecting cables and other auxiliary connecting equipment on high-end bicycles connected to the faucet. When disassembling the faucet, it must be removed together, which is not easy and troublesome to disassemble. Affecting the use efficiency is obviously not feasible and operable; the third is to drive the screw to move down by twisting the key to make a pair of pins lock the faucet. In terms of torque, it is very difficult, regardless of whether all Old and weak women and children can easily twist the key to drive the screw to do work to insert or pull out the faucet. If the faucet and other parts are slightly corroded or polluted by dust and mud, the original design intention is almost impossible to achieve.

In addition, Chinese patents 201020101477.6, 201020101425.9, and 201020101476.1 disclose an anti-theft remote control faucet lock device for electric bicycles, but its disadvantages are that the structure is complex, electric drive is required, the cost is high, and the reliability is low.
