Abstract

The utility model provides a steering wheel lock of vehicles, which is characterized in that the inner cavity of a hollow rod body is sheathed with a telescoping rod with continuous tooth troughs. The inner part of the clamping trough of the outer side of the vertical surface of the lock body is provided with an O-shaped lock pin, a spring and a press plate in sequence, and a snap ring which prevents a telescoping rod from being pulled out is arranged in the annular trough of the final end of the telescoping rod of a hexagonal prism. After the clamping tongue of the lower part of the O-shaped lock pin penetrates through the clamping tongue hole of the left segment of the hollow rod body, the clamping tongue is mutually matched or separated with the continuous tooth troughs on the telescoping rod in the hollow rod body. When the steering wheel needs locking, the telescoping rod is pulled out to the limit position that an upper lock hook and the vehicle disc are clamped, and the steering wheel is locked. When in opening, the lock core is toggled by a key to make the eccentric body of the lower end toggle the O-shaped lock pin to move outwards, and the lock pin is dismounted.

Description

Steering wheel lock of vehicles

The utility model relates to a kind of security insurance utensil, particularly a kind of employed steering wheel for vehicle lockset of locking direction dish that is used for.

In order to prevent that automobile is stolen or to cause the accident in order to prevent the unlicensed person from touching bearing circle, general driver all will not lock bearing circle at the scene the time, to prevent the generation of class incident.And the structure of the steering wheel for vehicle lockset of using always at present as shown in Figure 1, lock body is an outside hollow rod body 1 that coats garment bag layer 11, be set with lock body 3 at hollow rod body 1 left end, be equipped with plug body 4 in the lockhole of lock body 3, in one side bayonet slot 32 of lock body 3 steel ball 61 is housed, spring 6 and pressing plate 7, expansion link 2 movable sets that have taper annular groove spaced apart are in hollow rod body 1 and lock body 3, on hollow rod body 1 and expansion link 2, respectively have one with the bearing circle

cylindrical latch hook

12 and 21 of the outer fork of clip mutually, when needing the locking bearing circle, then with the evagination latch hook 12 on expansion link and the hollow rod body and 21 clips on the bearing circle cylindrical, then expansion link outwards is pulled out to the chucking position, use key lock again, steel ball 61 is fastened in the annular groove of expansion link 2, when needing to open, uses key rotation lock core body 4 again, make steel ball 61 withdraw from annular groove, expansion link is return shorten and be convenient to latch hook 21 to break away from bearing circle.Therefore, when opening or lock, all need use key rotation lock core body 4, just can reach the purpose of normal use, therefore, not too convenient.In addition, its locking relies on steel ball 61 spring 6 elastic force effects thereon to embed annular groove down and realizes, therefore, its locking degree is insecure, because the snap-latch surface of steel ball and annular groove is a very little arc surface, both very easy masterpieces outside firmly produce to slide and take off the lock phenomenon, so when the power that promotes expansion link 2 was big, then the radial component that expansion link produced is very easy ejected annular groove with steel ball 61, and the release accident that expansion link is withdrawn takes place, caused and lost car or unsafe hidden danger.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and when a kind of locking is provided without key, lock safe and reliable, the novel automobile Lockset on steering wheel that no expansion link contracts and retires and suffer from.

The realization of the utility model purpose is to be reached by following technical scheme, referring to Fig. 3.

Be set with at the hollow rod body left end lock body that off-centre is stirred the body lock core is housed, in the hollow rod body inner chamber, be set with the expansion link that has continuous teeth groove, in the draw-in groove in the lock body vertical surface outside degree of lip-rounding lock pin is housed successively, spring and pressing plate, in the flexible terminal annular groove of multiple edge body, be installed and prevent the clasp that expansion link is deviate from, the block tongue of degree of lip-rounding lock pin bottom pass behind the block tongue hole of hollow rod body left side section with its in expansion link on teeth groove fasten or break away from.In the time of must locking, expansion link is pulled out to latch hook and the stuck end position of hull, i.e. lockable on it, during unlatching, stir lock core with key and make its lower end eccentric body stir degree of lip-rounding lock pin to move outward, lock pin lower end block tongue is deviate from from teeth groove, be a kind ofly unblank conveniently, safe and reliable vehicle lock.

Therefore effect of the present utility model is significant:

Owing on two symmetrical block tongues of degree of lip-rounding lock pin lower end, designed a diagonal plane and a vertical surface, make expansion link when pulling out locking, teeth groove inclined-plane and block tongue inclined surface can freely be dialled the top slip on it, therefore, can arbitrarily adjust locked lengths, used to adapt to the bearing circle that all size varies in size, and, when pulling out locking, need not use key, as long as after the locking, then block tongue and teeth groove two vertical surfaces are just stuck, expansion link can not oppositely push back, what prevented to cause because of thrust is excessive moves back the lock sliding problem, makes locking more safe and reliable.In addition, owing to installed clasp additional, played the axial limiting effect that expansion link can not excessively be pulled out at expansion link multiple edge body end.
