Description

A kind of link gear of baseball lock

Technical field

The utility model belongs to lockset, particularly a kind of link gear of baseball lock.

Background technology

Automobile steering lock is the lockset commonly used of automobile burglar, has the product of multiple different structure at present, no matter that a kind of lock all has its deficiency.Baseball lock (being retractable vehicle steering lock) is exactly a kind of in the automobile steering lock.The locking and unblank of baseball lock pinned the steering wheel except the rotation that utilizes lockable mechanism control lock hook, also utilizes link gear to realize the clutch between lock handle and the lock hook, makes lock handle can drive lock hook and rotates and make the lock handle can be flexible in the lock body.The deficiency that the link gear of existing baseball lock exists is a unreasonable structure, and lock back or lock all can not push lock handle in the lock body vehicle steering of wounding easily when also having complete opening.

The utility model content

The purpose of the utility model provides the link gear that a kind of rational in infrastructure, simple, effective baseball is locked.

The solution of the utility model is: the link gear of baseball lock comprises: be located at the lock hook in the cylindric lock body, an end of lock hook is provided with loose collar, and lock handle is enclosed within the loose collar; It is characterized in that: the end of said loose collar is provided with at least one bayonet socket, and the circumferential activity of loose collar is fixed on the lock body, and the outer end of pasting loose collar is provided with the reseting plate that is fixed on the lock body, and the inner edge of reseting plate and the outer wall of lock handle are tangent; The end of said lock handle is provided with position limiting convex ring and cooperates with loose collar, and lock handle is provided with the bayonet fittings on elasticity fixture block and the loose collar; Be the plane towards the front of lock handle position limiting convex ring on the said elasticity fixture block, the back opposite with the front is the inclined-plane.

The end of said loose collar is provided with bulge loop, and said bayonet socket is located on the bulge loop, and loose collar is fixed on the lock body through the bulge loop activity, and the bulge loop outer end that said reseting plate is pasting loose collar is provided with the bayonet fittings on the elasticity fixture block on the lock handle and the bulge loop of loose collar.

The utility model is owing to adopt above-mentioned link gear, when locking, with lock handle vertically in lock body outwards during pull; Utilize the inclined-plane of elasticity fixture block back on the lock handle to cooperate with loose collar; The elasticity fixture block can be by in the loose collar compressing withdrawal lock handle, and the motion of lock handle is unrestricted, and the position limiting convex ring on it receives stopping of loose collar; Lock handle is in the extreme position when locking; At this moment the elasticity fixture block on the lock handle is positioned at circumferentially the corresponding position of bayonet socket on the bulge loop with loose collar, and the rotation lock handle can make the elasticity fixture block snap in the bayonet socket of loose collar, the interlock of realization lock handle and lock hook.Because the front of elasticity fixture block is that the plane cooperates with the end of loose collar on the lock handle, lock handle is locked and can not in lock body, moves vertically, when can prevent to lock back or lock also have complete opening lock handle is not pushed in the lock body vehicle steering of wounding.When unblanking, only need the rotation lock handle, utilize reseting plate, the elasticity fixture block is withdrawn in the lock handle, can lock handle be pushed in the lock body the stopping and oppress of elasticity fixture block.This shows that the link gear of the utility model has rational in infrastructure, simple, and is easy to use, advantage such as locking effect is good.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 3-Fig. 5 is respectively the sketch map that lock handle cooperates with loose collar in the utility model.

Fig. 6, Fig. 7 are respectively the sketch mapes that the utility model lock handle cooperates with reseting plate.

The specific embodiment

The baseball lock is as shown in Figure 1; Comprise: lock body cylindraceous 2, be located at waist shape lockhole 1 on the lock body 2, be located at lock body 2 front ends tapered end, be located at the latch hooks 3 that cooperate with waist shape lockhole 1 in the lock body 2, link and stretch out the lock handle 4 of lock body 2 rear end end caps 5 with lock hook, the front end of latch hook 3 is movably connected in the front end of lock body 2 and matches with lockable mechanism that tapered end S controls.The link gear of baseball lock, as shown in Figure 2, comprise lock hook 3, an end of lock hook 3 is provided with tubulose loose collar 7, and lock handle 4 is enclosed within the loose collar 7; The rear end of latch hook 3 is fixedly connected with loose collar 7; The end of loose collar 7 is provided with bulge loop 701; Bulge loop 701 is provided with one or more bayonet sockets 702; Rear end in the lock body 2 is fixed with a pressure ring 6, and pressure ring 6 is fixed on end cap 5 on the pressure ring 6 with screw 10 from the bulge loop 701 that axially is stuck in loose collar 7; Bulge loop 701 outer ends of pasting loose collar 7 are provided with the reseting plate 8 that is fixed on the lock body rear end end cap 5, the inner edge 801 of reseting plate 8 and the outer wall tangent (referring to Fig. 6) of lock handle 4; Loose collar 7 also can not established bulge loop 701, and bayonet socket 702 is located at the end of loose collar 7, and the end that reseting plate 8 is pasting loose collar 7 is provided with, and loose collar 7 places in the pressure ring 6, circumferentially is fixed on the lock body 2 through pressure ring 6; Lock handle 4 places loose collar 7 internal clearances to cooperate; The end of lock handle 4 is provided with position limiting convex ring 401 and cooperates with loose collar 7; The elasticity fixture block 402 that lock handle 4 is provided with two symmetries cooperates with bayonet socket 702 on the bulge loop 701 of loose collar 7, is provided with back-moving spring 403 (referring to Fig. 4,6) between the elasticity fixture block 402; As shown in Figure 3, the front 4021 towards lock handle position limiting convex ring 401 on the elasticity fixture block 402 is the plane, with 4021 opposite back 4022, front be the inclined-plane; Be provided with the cushion rubber 9 that is enclosed within on the lock handle 4 in the end cap 5.

Operating principle: when locking; Shown in Fig. 3-5; With respect to loose collar 7 outside pull in the lock body vertically, the inclined-plane of elasticity fixture block 402 back 4022 on the lock handle 4 is by in the loose collar 7 compressing withdrawal lock handles 4 with lock handle 4, and the position limiting convex ring 401 on it receives stopping of loose collar 7; Lock handle 4 is in the extreme position when locking; At this moment the elasticity fixture block 402 on the lock handle 4 is positioned at circumferentially the corresponding position of bayonet socket 702 on the bulge loop 701 with loose collar 7, and rotation lock snaps in the bayonet socket 702 of loose collar 7 elasticity fixture block 402, the interlock of realization lock handle and lock hook.Because the front 4021 of elasticity fixture block 402 is that the plane cooperates with the end of loose collar 7 on the lock handle 4; Lock handle 4 is locked relative loose collar 7 and can not in lock body, moves vertically; Can prevent to lock back or lock when also having complete opening lock handle is pushed in the lock body vehicle steering of wounding.When unblanking, like Fig. 6, shown in 7, only need rotation lock 4, utilize stopping and oppressing of 8 pairs of elasticity fixture blocks 402 of reseting plate, elasticity fixture block 402 is withdrawn in the lock handles 4, lock handle 4 relative loose collars 7 can push in the lock body.
