CN202110990U - Housing of automobile anti-theft igniting lock - Google Patents

Abstract

The utility model relates to a housing of an automobile igniting lock, in particular to a housing of an automobile anti-theft igniting lock with a lock tongue arranged on an automobile steering column. By improving the structure of the housing of the igniting lock and unchanging the other parts, the anti-theft function of the lock tongue of the igniting lock is guaranteed. The housing of the automobile anti-theft igniting lock consists of a body, a clamped semicircular block and a lock tongue embedding part, wherein the body is assembled with the clamped semicircular block into a whole body, the end of the clamped semicircular block is provided with a lock tongue embedding part hole which is tightly matched with the lock tongue embedding part, a smaller connecting block hole is arranged behind the lock tongue embedding part hole to be in sliding matched with a connecting block, the bottom of the hole is sealed and extruded to be provided with a pressure spring boss, and an assembly sequence is as follows: a pressure spring is firstly sheathed on the pressure spring box, the connecting block and the lock tongue are arranged, the lock tongue embedding part is arranged, and the lock tongue embedding part is tightly pressed into the lock tongue embedding part hole. The housing of the automobile anti-theft igniting lock has the beneficial effects that the extruded part of the housing is a whole body, so that the lock is hard to prize up and the pressure spring is hard to take away by an automobile robber, therefore, the anti-theft property of the igniting lock is enhanced; and the powerful riveting of a lock cover is saved, the cost is saved, and the housing of the automobile igniting lock is convenient to manufacture.

Description

A kind of automobile burglar ignition lock housing

Technical field

The utility model relates to a kind of automotive ignition lock shell, especially relates to a kind of automobile burglar ignition lock housing that has dead bolt on the automobile steering post that is installed in.

Background technology

In order to guard against theft, automobile generally adopts ignition lock is installed on the automobile steering post at present, embraces the direction post through the clamping semicircle piece on the lock shell, connects Hough and two again and twists into two parts screw, makes the ignition lock housing fastening and can not normally dismantle from the direction post.Simultaneously, dead bolt is housed also in the ignition lock housing, when automobile key was extracted, dead bolt just ejected from clamping the semicircle piece, is inserted in the groove on the direction post, and steering wheel can't be rotated, and automobile can't be gone.Existing dead bolt and contiguous block are from the reverse side open slot that clamps the semicircle piece, to pack into, the lock core connecting rod of then laterally packing into, and locking closure, stage clip to the direction post, turn over riveting with the dead bolt top at last on press-fiting then, and locking closure is fixed on the housing.This structure makes dead bolt receive ejecting force all the time, after key inserts rotation, promptly drives contiguous block through lock core connecting rod, just dead bolt is pushed away the direction post, and steering wheel could rotate.Though this structure is easily manufactured, but there is a fatal weakness, it is too poor to turn over riveting intensity exactly; Locking closure riveted joint is easy to the stolen car thief and pries open after living, in case and locking closure has not had; Stage clip ejects immediately; Dead bolt does not have stage clip just can release the direction post freely, and steering wheel also just can rotate, and this anti-theft feature is also just useless.This hidden danger needs to be resolved hurrily.

Summary of the invention

The purpose of the utility model is to overcome the hidden danger that exists on the prior art structure, and only through improvement ignition lock shell structure, and other parts are not changed, and guarantee the automobile burglar ignition lock housing of the anti-theft feature of ignition lock dead bolt.

The purpose of the utility model is achieved in that a kind of automobile burglar ignition lock housing, is made up of body, clamping semicircle piece, dead bolt inserts, and body is an integral body with clamping the semicircle piece; Said clamping semicircle piece end has a dead bolt insert hole, and close-fitting is gone into the dead bolt inserts, is less contiguous block hole behind the dead bolt insert hole; Contiguous block is allocated in slip into, seals at the bottom of the hole, is raised with the stage clip boss; Assemble sequence is earlier compression spring sleeve to be installed to the stage clip boss; Reinstall contiguous block and dead bolt, load onto the dead bolt inserts at last, and be pressed onto the dead bolt insert hole.

The profile of said dead bolt inserts can be oval inserts, rectangle inserts or other shapes.

Compared with prior art, the beneficial effect of the utility model is: the exposed parts of housing is whole, and cartheft is difficult to pry open, and more is difficult to take out stage clip, makes the anti-theft capability of ignition lock strengthen; The same brute force riveted joint of having saved locking closure provides cost savings, and also is convenient to make.

Among the figure: body 1, locking closure 2, stage clip 3, stage clip boss 4, riveted joint position 5, lock core connecting rod 6; Lock core hole 7, contiguous block 8, dead bolt 9 clamps semicircle piece 10, dead bolt insert hole 12; Dead bolt inserts 13, oval inserts 14, rectangle inserts 15, lock core connecting rod hole 16, contiguous block hole 17.

Embodiment

Below in conjunction with description of drawings and embodiment the utility model is done further description, but be not restriction its protection range.

Referring to Fig. 1, Fig. 2, be the structural representation of the utility model and the structural representation of dead bolt inserts, a kind of automobile burglar ignition lock housing; Be made up of body 1, clamping semicircle piece 10, dead bolt inserts 13, said body 1 is an integral body with clamping semicircle piece 10, and said clamping semicircle piece 10 ends have a dead bolt insert hole 12; Close-fitting is gone into dead bolt inserts 13, is less contiguous block hole 17 behind dead bolt insert hole 12, slides and allocates contiguous block 8 into; Seal at the bottom of the hole, be raised with stage clip boss 4, body 1 is except that the hole underseal being closed and having dead bolt insert hole 12 at clamping semicircle piece 10; Close-fitting is gone into outside the dead bolt inserts 13; All the other are all identical with existing body, and the existing part of allocating into uses fully, are assembled to lock core connecting rod hole 16 etc. such as lock core connecting rod 6.Assemble sequence is earlier stage clip 3 covers to be installed to stage clip boss 4, reinstalls contiguous block 8 and dead bolt 9, loads onto dead bolt inserts 13 at last, and is pressed onto dead bolt insert hole 12.Because the close-fitting power of dead bolt inserts 13 and dead bolt insert hole 12 is greater than stage clip 3 power, dead bolt inserts 13 can not come off from dead bolt insert hole 12 in producing storage process; In case after the entrucking; Because it is middle with clamping semicircle piece 10 that dead bolt inserts 13 is inclusive in the direction post, it is fastening to be twisted into two parts screw, therefore also can not produce; Cartheft also can't be pried open body 1, also can't change the locking state of dead bolt 9.

Referring to the sketch map of the oval dead bolt inserts of Fig. 3 and the sketch map of Fig. 4 rectangle dead bolt inserts, the profile of said dead bolt inserts 13, can be oval inserts 14, rectangle inserts 15 or other shapes.Though be difform profile, all join identical dead bolt 9 in the dead bolt inserts 13.

Referring to Fig. 5, be the prior art constructions sketch map, body 1 is an integral body with clamping semicircle piece 10, assemble sequence is the dead bolt 9 of packing into earlier; Contiguous block 8, stage clip 3 inserts stage clips 3 with the stage clip boss of locking closure 24 then, flattens to carry out brute force at riveted joint position 5 and press again; Lock core connecting rod 6 laterally penetrates, when lock core insertion lock core hole 7, and insertion, key, then dead bolt 9 withdrawals; If extract key, then under the effect of stage clip 3, dead bolt 9 direction of insertion posts, and pin steering wheel.
