Description

Automobile spare tire anti-theft lock device

The utility model belongs to automobile spare tire lifter anti-joyride device, relates to the flexible rotary type anti-theft column lock of a kind of separating and combining.Be applicable to automobile rearing-box plate bottom, manpower rotary type spare tire lifter anti-theft column lock.

At present, automobile spare tire anti-joyride device has the employing warning device, its person with foresight's condition be the driver must be on the scene or warning circuit if exist so hinder will be malfunctioning; Adopt anti-joyride device in addition, as Chinese patent CN2159916Y " vehicle spare tire anti-joyride device ", its needs to bore four holes on big of automobile tapered end is installed, and rocking bar is locked again, and its theftproof performance is poor, and inconvenience is installed.

The purpose of this utility model provides a kind of automobile spare tire anti-theft lock device that is installed on the automobile spare tire lifter.This spare tire anti-theft lock device is to realize flexible separating and combining by the crank of spare tyre lifter transmission shaft bonded assembly drive link and lockset control transmission shaft.

The utility model automobile spare tire anti-theft lock device, comprise lock core, crank draw-in groove and with automobile spare tire lifter bonded assembly in pipe driving cog pipe, it is characterized in that in a tubular form interior pipe driving cog pipe and outer slide teeth pipe box dress form, in pipe driving cog pipe rearward end have successively with the connecting bore of automotive spare tire hoist and with the flexible bonded assembly of outer tube in pipe clutch tooth, front end is equipped with the location plug and the return back-up ring of lock core, fixed lock core, and pipe stopper slideway in having, stopper is housed in the slideway; Outer tube slide teeth pipe rearward end is followed successively by pin pillar and outer tube clutch tooth, and leading section has the crank draw-in groove, and is provided with boss outer tube location stopper.

This device is flexible clutch rotary type anti-theft column lock, and connecting bore of pipe is connected with the drive link of automotive spare tire hoist in it.During use, key is inserted up time Rotate 180 degree, promptly stopper to moving forward to the location plug, is combined as a whole inside and outside clutch tooth in slideway, connecting bore and crank groove expose simultaneously, just can install, the lifting spare tyre.During lock, outer tube is pushed back, inner and outer pipe clutch tooth separates, and the contrary turnback of key is taken out and get final product, and outer pillar was about to connecting bore and protected this moment, and can rotate arbitrarily, thereby had played the effect of protecting.

The utility model has following advantage compared with the prior art:

1 device be intended to pin external tooth pipe and internal tooth pipe can not in conjunction with, the external tooth pipe can rotate arbitrarily, and makes the spare tyre can not lifting;

2 theftproof performance height, easy for installation, cost is low;

3 is applied widely, can grow, can lack, and is used for 25 tons to 20 tons various vehicles;

In addition, also be applicable to the mechanical transmission-type lockset that is similar to this structure.
