Description

Handle lock

(1) technical field

The utility model is the handle lock about a kind of vehicle steering.

(2) background technology

Handle lock mainly is the anti-joyride device as vehicle steering, early stage handle lock structure, as US Patent the 4th, 856, No. 308 " automobile steering lock ", it is by movable body, closing appliance and expansion link constitute, cooperation is referring to shown in Figure 8, in the housing (61) of its closing appliance (60) lock core (62) is set, the deadlock lever (621) of lock core (62) is positioned at the deep-slotted chip breaker (631) of expansion link (63) and locates, compress object and in the housing (61) of the relative side in addition of lock core (62), steel ball (64) and spring (65) etc. are set, design by this, rotated and can key plug lock core (62), expansion link (63) is locked pulls or is unlocked, locked and pulled and handle lock can be arranged at the bearing circle inner edge, though this handle lock can be by the deadlock lever (621) and the steel ball (64) of lock core (62), spring (65) carries out relative clamping for the deep-slotted chip breaker (631) of expansion link (63), and make expansion link (63) can be locked the location of pulling, and the effect that compresses of steel ball (64) and spring (65), when expansion link (63) suffers powerful the stretching, to make deep-slotted chip breaker (631) with antagonistic force pushing and pressing steel ball (64) and compression spring (65), cause deep-slotted chip breaker (631) can cross steel ball (64), form that handle lock goes to pot and ineffective.

As relevant automobile steering lock in the patent case of Taiwan, as application case number No. 82204477 " improvement of automobile steering lock blocking device ", it has a mobile, one expansion link, an one crotch sleeve pipe and a lock structure, this lock structure is by the lock core of semi-circular lock core dwang and a L shape coupler body, one button bolt, one lining body member is formed, order button bolt is set the groove into expansion link, so that it limits moving of expansion link, and this handle lock is except lock core, L shape coupler body need be set again, spring and buckle bolt, cause integrally-built complexity, make cost higher and be unfavorable for making assembling.

And as Taiwan patent application case number No. 87212945 " anti-joyride device of vehicle steering ", first and second parallel storage tank then need be set in hollow housing, first and second body is set respectively in first and second storage tank, first body has first and second arm, second body has third and fourth arm, and a connecting rod, one first hooking sheet, one second hooking sheet need be set in hollow housing, generally speaking not have the advantage that structure is simplified.

As Taiwan patent application case number No. 86207384 " handle lock and structural improvement ", it comprises that a lock body, a staggered left and right horizontal fork arm and that is placed in the body horizontal concrete chute be located at the vertical fork arm in vertical chute, an and slipper of being located in the lock body horizontal concrete chute, and mainly must cover bearing circle at the square shape containment body of lock body, and prevent that its internal security air bag is stolen, and this special construction pulls for not having an automobile steering lock of safety air bag, and its architectural feature is too complex and takies too many installing space.

And as Taiwan patent application case number No. 85207069 " multiple-effect anti-theft steering wheel lock ", it mainly is made up of securing rod and lock main body and fixed link, two ends are run through for circle hole groove in its lock main body central authorities, be provided with a grade body raised line in the groove, in the groove and insert lock core body, loudspeaker and loudspeaker protecting cover and circuit arrangement and battery chamber, its design feature is to send the loudspeaker sound and reaches the alarm effect, though this structure is different from other handle lock, and the complexity of its structure improves relatively, and popularization is not high.

Other handle lock structure design, append one " automobile steering lock (appending one) " as Taiwan patent application case number the 82211603rd, application case appends four " lockset of latch hook on vehicle steering appends (four) automatically " number No. 79202386, application case number No. 82206516 " improvement of automobile steering lock lock body ", application case number No. 82204387 " vehicle steering lockset " .. etc., be the different handle lock structure of majority kind, the use and the lock that can be used as vehicle steering is equally pulled, yet, its ubiquitous shortcoming is, the spare part complexity of lock structure, and make the higher and assembling difficulty of cost.
