Abstract

The utility model relates to a lock for the steering wheels of automobiles. An open slot on a body is clamped on the outer frame of a steering wheel and the hook body of a hooking rod is arranged close to the open slot to form the locking state. The body is combined with a latching mechanism by a lock hole. The hook body and the open slot can be separated by a key. A ratchet wheel is arranged on the hooking rod. A one-way ratchet circularly arranged on a cover plate can be clamped or separated by the clamping teeth of a clamping block to enable the hookingrod and the cover plate to do locking or unlocking actions. The utility model not only can be used for locking steering wheels, but also can be used for preventing air bags from being stolen.

Description

A kind of automobile steering lock

The utility model relates to a kind of automobile steering lock, refers in particular to a kind of not only lockable vehicle steering but also can prevent the automobile steering lock that the automotive safety steam pocket is stolen.

A kind of " three-dimensional braking direction dish lock ", mainly be that a end in its retractable lock rod is provided with a U-shaped fork arm and establishes a L shaped fork arm at the other end, pitch respectively on bearing circle, other has expansion link vertical extent one resistance lever forward, pass in the middle of the bearing circle and be against the interior concave space of instrument carrier panel, form the latch-up structure of three place's fixed-direction dishes.But this automobile steering lock can only the locking direction dish, can not protect the safety air bag of automobile.

The purpose of this utility model is to provide a kind of not only lockable vehicle steering but also can prevents that the safety vehicle capsule on the bearing circle is stolen.

The purpose of this utility model realizes by following technological means: a kind of automobile steering lock, constitute by body, shank, latching device and cover plate, it is characterized in that: body has the bar of suitable length, with the open slot holding at the bearing circle housing, and the coupler body of shank sealing, body has axis hole can articulate shank, and body combines with the lockset of latching device with lockhole, and the body grooved hole can supply to be articulated in the ratchet of latch hook and the ring of cover plate becomes position rotating; The straight bar part of shank is articulated in the body axis hole and becomes position rotating, and shank two ends are bent into coupler body, and the ratchet of one is arranged on the shank, and ratchet has ratchet to be snapped in or to leave by the clamping block latch of latching device; Latching device is combined in the body lockhole by lockset, comprises movable block, clamping block and elastic element in the latching device, and latch is arranged on the movable block, and is subjected to the elastic element pushing tow; Cover plate is made with firm material, can be articulated in the straight-bar position of shank by a ring, and the ring appearance has unidirectional ratchet.Can establish Car Burglar Alarm on this scheme cover plate.

Advantage of the present utility model is: not only can prevent that automobile is stolen but also can protect the not stolen automobile steering lock of safety air bag on the bearing circle by the locking direction dish.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 exploded perspective view of the present utility model.

Fig. 2 is of the present utility model to face part sectional view.

Fig. 3 side-looking part sectional view of the present utility model.

Fig. 4 is the action diagram of Fig. 3.

Among the figure: 1 body, 11 bars, 12 open slots, 13 axis holes, 14 slotted eyes, 2 shanks, 21 coupler bodies, 22 setting elements, 23 ratchets, 231 unidirectional ratchets, 3 latching devices, 31 locksets, 32 movable blocks, 33 clamping blocks, 331 latches, 4 cover plates, 41 rings, 411 unidirectional ratchets, 42 Car Burglar Alarms, 5 bearing circle, 51 instrument carrier panels

As shown in Figure 1, the utility model is made up of body 1, shank 2, latching device 3 and cover plate 4.Wherein: body 1 has a bar 11 than length can be stuck on the instrument carrier panel of automobile, rotates to stop bearing circle, and body 1 is stuck in the direction housing with open slot 12, and axis hole 13 is for also articulating rotation for shank 2 in conjunction with shank 2.Shank 2 is articulated in the axis hole 13 of body 1 with straight-bar portion, coupler body 2 two ends are formed coupler body 21 by complications, and rotation shank 2 makes the open slot 12 of coupler body 21 corrals at body 1, deviate from the restriction shank, or, car body 1 is separated with the vehicle steering housing away from the opening notch; Shank 2 is fixed with ratchet 23 with setting element 22, and unidirectional ratchet 231 is arranged on the ratchet 23, and shank 2 can be located, or makes its directed rotation; The straight bar part of shank 2 can be pivoted by a ring 41 of cover plate 4, and ring 41 snaps in 14 one-tenth position rotating of cross-drilled hole of body 1.

Latching device 3 is bonded to the lockhole 15 of body 1 by lockset 31, the core of lockset 31 is under key drives, pressing action piece 32 rises, movable block 32 is attached to two clamping blocks, 33 downsides, two clamping blocks 33 are subjected to elastic element 34 compressings, make the latch 331 of clamping block 33 snap in the set ratchet 411 of ring 41 of the single direction ratchet 231 of ratchet 23 and cover plate 4, do unidirectional rotation with restriction ratchet 23 and cover plate 4, and when movable block 32 rises under core drives, can oppress two clamping blocks 33 and rise, like this, wherein the latch 331 of a clamping block 33 separates with the unidirectional ratchet 231 of ratchet 23, therefore, the shank 2 that integrally combines with ratchet 23 can be done any revolution; The latch 331 of another clamping block 33 separates with ring 41, so cover plate 4 also can freely turn round.

The firm material of cover plate 4 usefulness is made, can be articulated in the straight-bar position of shank 2 by a ring 41, its lateral part, a side is limited by ratchet 23, and opposite side is limited by slotted eye 14, make cover plate 4 according to 41 one-tenth position rotating of ring, encircle 41 external diameters and be provided with unidirectional ratchet 411, and can be snapped in, can the safety air bag direction be installed to vehicle steering with restriction cover plate 4 and rotate by the latch 331 of clamping block 33, and when latch 331 separated with unidirectional ratchet 41, cover plate 4 can become contrarotation; In order to make cover plate 4 have better safe antitheft effect, can also add Car Burglar Alarm 42 on the cover plate 4.

As shown in Figures 2 and 3; during use; utilize body 1 set open slot 12 to rest the vehicle steering housing, rotation shank 2 makes coupler body 21 near open slot 12; body 1 is fixed on the bearing circle 5; and the bar 11 of body 1 is stretched on instrument carrier panel 51, and at this moment, cover plate 4 also hides the position of safety air bag on bearing circle 5; make bearing circle 5 lockings, and can protect safe capsule.

As shown in Figure 4, when needs are got body 1 from bearing circle 5, can start movable block 32 with key rises, make the latch 331 of clamping block 33 leave ratchet 23 and encircle 41

unidirectional ratchet

231 and 411, like this, shank 2 and cover plate 4 promptly can become releasing orientation and can reverse, and make the coupler body 21 of shank 2 leave open slot 12, the safety air bag position of cover plate 4 on can departure direction dish 5, body 1 be desirable from.
