Description
Technical field
The utility model 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 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 utilizes lockable mechanism control lock hook rotation lock to live steering wheel.The deficiency that the link gear of existing baseball lock exists is a complex structure, is out of order easily, and anti-damage ability is poor.
The utility model content
The purpose of the utility model provides the lockable mechanism of the baseball lock of a kind of rational in infrastructure, anti-destructive and good reliability.
The solution of the utility model 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 is fixed with gear stand, and an end of gear stand is provided with the hollow shaft of tape spool to groove; One fixed gear that is connected with said lock hook is enclosed within on the hollow shaft on the gear stand; The axial active card of one free gear quilt in the groove of gear stand hollow shaft is circumferentially spacing, and axially adopts ratchet to cooperate with said fixed gear; One geared sleeve is fixed on the hollow shaft of gear stand fixed gear and free gear is covered, and between geared sleeve and free gear, is provided with return spring; 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.
The characteristics of the utility model; The one, rational in infrastructure; Between gear stand and geared sleeve, adopt a fixed gear 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 lock is tight more more, can improve lock body and be fixed on the firmness on the steering wheel; The 2nd, rotatable parts (latch hook) cooperate through end face ratchet between two gears with stop bit between the fixed part (gear stand on the lock body); The ratchet contact surface is big, is difficult to be destroyed, 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 convenience of using.More than these characteristics remedied the defective of such anti-theft product in the market.
Below in conjunction with accompanying drawing the utility model is described further.

The specific embodiment
The baseball lock is as shown in Figure 1; Comprise: lock body cylindraceous 2, 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 and stretch out the lock handle 6 of lock body 2 rear end end caps 5 with lock hook 3, 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.Said lockable mechanism comprises like Fig. 2, shown in 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 retainer plate 12, has been screwed tapered end cover 1 on the retainer plate 12, and retainer plate 12 also is provided with a plurality of bayonet sockets 1201; Be fixed with gear stand 7 on the retainer plate 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 retainer plate 12, and opposite side is provided with hollow shaft 702, and hollow shaft 702 walls are provided with axial groove 703; Fixed gear 8 is enclosed within on the hollow shaft 702 of gear stand 7, and the cylindrical of fixed gear 8 is cemented in the annular end 301 of latch hook 3; It is axially corresponding with fixed gear 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 through 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 8; One geared sleeve 10 5 is fixed on the hollow shaft 702 of gear stand 7 fixed gear 8 and free gear 9 is covered through pinning, and between geared sleeve 10 and free gear 9, is provided with return spring 11; The lock cores 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 match 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 can only allow one of them gear with respect to another gear one-directional rotation for facing directly after two gear 8,9 engagements.
Operating principle
Lock: as shown in Figure 5; V-depression 901 matches on prominent 401 of the V-arrangement that makes the lock core tail end with key rotation lock core and the free gear 9; Free gear 9 meshes with fixed gear 8 under the effect of return spring 11, behind the extraction key, can drive latch hook 3 through lock handle 6 and rotate completion locking to steering wheel; Because the employing ratchet cooperates between free gear 9 and the fixed gear 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 8 along hollow shaft 702 axially-movables of gear stand 7, at this moment can drive latch hook 3 through lock handle 6 and rotate completion unblanking to steering wheel.
