Abstract
The invention discloses a locking mechanism of a baseball lock. The locking mechanism comprises a tubular lock body and a lock hook in the lock body, wherein the end provided with a lock head in the lock body is fixedly provided with a gear bracket; one end of the gear bracket is provided with a hollow shaft with an axial groove; a fixed gear which is connected with the lock hook is sleeved on the hollow shaft on the gear bracket; a movable gear is axially and movably clamped in the groove of the hollow shaft of the gear bracket to be circumferentially positioned and is axially matched with the fixed gear by using a ratchet; a gear sleeve is fixedly arranged on the hollow shaft of the gear bracket to cover the fixed gear and the movable gear; a return spring is arranged between the gear sleeve and the movable gear; and the end face, opposite to the fixed gear, on the movable gear is provided with a V-shaped groove to be matched with a V-shaped convex head which is arranged at the tail end of a lock core in the lock head. The locking mechanism has the advantages of rational structure, good damage resistance, high reliability, convenience in use and the like.
Description
Technical field
The invention belongs to lockset, particularly a kind of lockable mechanism 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 has its deficiency.Baseball lock (being retractable vehicle steering lock) is exactly a kind of in the automobile steering lock.The lockable mechanism control lock hook rotation pinning bearing circle of locking and unblank to utilize of baseball lock.The deficiency that the link gear of existing baseball lock exists is complex structure, is out of order easily, and anti-damage ability is poor.
Summary of the invention
The lockable mechanism that the purpose of this invention is to provide the baseball lock of a kind of rational in infrastructure, anti-destructive and good reliability.
Solution of the present invention is: the lockable mechanism of baseball lock, comprise the lock body of tubulose, the lock hook in the lock body, and an end that is provided with tapered end in the lock body fixedly has gear stand, and an end of gear stand is provided with tape spool to the hollow shaft of groove; One fixed gear wheel that is connected with described lock hook is enclosed within on the hollow shaft on the gear stand; The axial active card of one free gear by circumferentially spacing, and axially adopts ratchet to cooperate with described fixed gear wheel in the groove of gear stand hollow shaft; One geared sleeve is fixed on the hollow shaft of gear stand fixed gear wheel and free gear is covered, and is provided with pull back spring between geared sleeve and free gear; The lock core that the end face of relative fixed gear is provided with in v-depression and the tapered end on the free gear matches at the prominent head of V-arrangement that tail end is provided with.
Characteristics of the present invention, the one, rational in infrastructure, between gear stand and geared sleeve, adopt a fixed gear wheel and a free gear end face ratchet to cooperate, utilize lock core to control the clutch of two gears, under locking state, only allow latch hook to rotate towards the locking direction, and more lock is more tight, can improve lock body and be fixed on firmness on the bearing circle; The 2nd, rotatable parts (latch hook) cooperate by end face ratchet between two gears with stop bit between the fixed parts (gear stand on the lock body), the ratchet contact surface is big, is difficult to destroyedly, and stop bit is effective, improve the anti-damage ability of product widely, thereby strengthened security of products; The 3rd, extract key after two gears can mesh automatically, improved the comfort feature that uses.More than these characteristics remedied the defective of such anti-theft product in the market.
The invention will be further described below in conjunction with accompanying drawing.

The specific embodiment
The baseball lock as shown in Figure 1, comprise: lock body 2 cylindraceous, be located at waist shape lockhole 201 on the lock body 2, be located at lock body 2 front ends tapered end 4, be located at the latch hooks 3 that cooperate with waist shape lockhole 201 in the lock body 2, link with lock hook 3 and stretch out the lock handle 6 of lock body 2 rear end end caps 5, 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 4 is controlled.Described lockable mechanism comprises shown in Fig. 2,5: the lock hook 3 in lock body 2, the lock body 2, and an end that is provided with tapered end 4 in the lock body 2 is welded with mounting ring 12, has been screwed tapered end cover 1 on the mounting ring 12, and mounting ring 12 also is provided with a plurality of bayonet sockets 1201; Gear stand 7 is fixedly arranged on the mounting ring 12; Gear stand 7 (referring to Fig. 3,4) comprises an annulus part 704, and a side of annulus part 704 is provided with in the bayonet socket 1201 that a plurality of boss 701 are stuck in mounting ring 12, and opposite side is provided with hollow shaft 702, and hollow shaft 702 walls are provided with axial groove 703; Fixed gear wheel 8 is enclosed within on the hollow shaft 702 of gear stand 7, and the cylindrical of fixed gear wheel 8 is cemented in the annular end 301 of latch hook 3; It is axially corresponding with fixed gear wheel 8 also to be with a free gear 9 on the hollow shaft 702 of gear stand 7; The horizontal bar 901 that free gear 9 is provided with two semicircle orifices 902 and is formed by two semicircle orifices 902, free gear 9 is actively set on the hollow shaft 702 of gear stand 7 by semicircle orifice 902, horizontal bar 901 is stuck in the groove 703 of hollow shaft 702 makes free gear 9 circumferentially spacing, adopt ratchet to cooperate between free gear 9 and the fixed gear wheel 8; One geared sleeve 10 is fixed on by pin 5 on the hollow shaft 702 of gear stand 7 fixed gear wheel 8 and free gear 9 is covered, and is provided with pull back spring 11 between geared sleeve 10 and free gear 9; The lock core that the end face of relative fixed gear 8 is provided with in v-depression 901 and the tapered end 4 on the free gear 9 matches at prominent 401 of the V-arrangement that tail end is provided with; The one side of ratchet is the inclined-plane, and another side is for facing directly, can only allow one of them gear with respect to another gear unidirectional rotation after two gears 8,9 engagements.
Principle of work
Lock: as shown in Figure 5, with key rotation lock core prominent 401 of the V-arrangement of lock core tail end matched with v-depression 901 on the free gear 9, free gear 9 meshes with fixed gear wheel 8 under the effect of pull back spring 11, after extracting key out, can drive latch hook 3 rotations by lock handle 6 and finish locking to bearing circle, because the employing ratchet cooperates between free gear 9 and the fixed gear wheel 8, will lock tighter and tighter in the process of locking; Unblank: as shown in Figure 6, use key rotation lock core, prominent 401 of the V-arrangement of lock core tail end forces free gear 9 to separate with fixed gear wheel 8 along hollow shaft 702 axial motions of gear stand 7, at this moment can drive latch hook 3 rotations by lock handle 6 and finish unblanking to bearing circle.
