Description

The antitheft pin of automobile and four-wheel

The utility model relates to a kind of lockset, specifically a kind of automobile and the antitheft pin of four-wheel.

At present, the anti-theft column lock that is used for automobile mainly contains the direction lock of lock bearing circle and electronic anti-theft alarm etc., and these lock classes and annunciator are not very effective, can't resolve the stolen problem of wheel as handle lock, and be just inoperative such as the annunciator of cutting off the electricity supply yet.

The purpose of this utility model provides the four-wheel that automobile can pin in a kind of elder generation, thereby prevents that effectively vehicle and four-wheel are stolen.

The purpose of this utility model is achieved in that gear and the thread transmission that key door control is arranged by, drives latch fitting and passes the wheel hub bore of wheel with wheel locking.Specifically be achieved in that and open key door earlier, the crank turning gear wheel shaft that has square hole with a front end, the drive overbolt rotates, driving cranking arm of cooperating with overbolt stretches out and passes the wheel hub bore from lock housing and sleeve pipe, pull out the lock bridge traverse and block pit on the lock bridge medial surface with the fixing pin of the end of cranking arm, at this moment the backward rotation crank is locked the lock bridge tension again, takes off crank at last and locks key door.

Owing to adopted such scheme, automobile and four-wheel can be pinned, play all theft-proof effect of automobile and four-wheel.

Below in conjunction with drawings and Examples the utility model is further specified; Fig. 1 is the part sectional view of the utility model front view, Fig. 2 is the partial front elevation view of cranking arm, Fig. 3 is the section-drawing of the A-A face of Fig. 2, Fig. 4 is the front view of crank, Fig. 5 is the fixing front view of pincers of " U " shape of lock, and Fig. 6 is the front view of " O " shape lock bridge, and Fig. 7 is the front view of sleeve pipe of cranking arm, Fig. 8 is the section-drawing of Fig. 7 B-B face, and Fig. 9 is the part province sketch map of the external form of the utility model main body.

Among the figure: 1, locking closure, 2, groove, 3, quadrangular, 4, moving gear, 5, gear case, 6, the nut of cranking arm, 7, overbolt, 8, the nut sheath, 9, steel rope, 10, wire rope casing, 11, steel wire rope groove, 12, fixing screw, 13, " O " shape lock bridge, 14, crank arm 15, the sleeve pipe of cranking arm, 16, bolt with flange, 17, flange, 18, driven gear, 19, the shell of cranking arm, 20, position-limitting pin, 21, the lock bridge chamber, 22, bump the hole of bead, 23, the quadrangular chamber, 24, crank, 25, the interior ring of " O " shape lock bridge, 26, bump pearl, 27, the lock bridge pit, 28, the sleeve pipe knock hole of cranking arm, " U " shapes of 29 locks are pincers fixedly.

In Fig. 1, moving gear (4), driven gear (18) are positioned in the gear case (5), and an end of moving gear (4) axle is quadrangular (3), can lock in the outside of quadrangular (3), and (2) are the groove on the lockset, and (1) is locking closure.Driven gear (18) two ends are connected with an overbolt (7) respectively, the outer end of overbolt (7) has steel wire rope groove (11), steel rope (9) is just around wherein, (10) be wire rope casing, the supporting with it nut nut (6) of promptly cranking arm is arranged on overbolt (7), and crank arm (14) of one, there is the structure of a tubulose the crank arm front portion of (14), be lock bridge chamber (21), " O " shape lock bridge (13) is not in that the time spent just is placed on wherein, the front end in lock bridge chamber (21) has pin (20), and it can cooperate with the lock bridge pit (27) at the interior ring (25) of " O " shape lock bridge middle part, so that block " O " shape lock bridge (13).(19) be the shell of cranking arm, it is the outside that is welded in bolt sheath (8), in bolt sheath (8), be equipped with the sleeve pipe of cranking arm (15), crank arm (14) be exactly that the length of the sleeve pipe of cranking arm (15) can be regulated by fixing screw (12) and the knock hole of cranking arm (28) from the sleeve pipe of cranking arm (15) the turnover shell (19) of cranking arm.Bolt sheath (8) is to be fixed on the gear case (5) by bolt with flange (16) by the flange (17) with its one.

As seen from Figure 2: lock bridge chamber (21) front end is a wedge shape, tommy (20) is at its front end, this structure can guarantee " O " shape lock bridge (13) turnover smoothly, and can be around pin (20) traverse, so that located at " O " shape lock bridge pit (27) by pin (20) is stuck, the rear portion in lock bridge chamber (21) have on an energy and " O " shape lock bridge (13) bump that pearl (26) matches bump the hole of bead (22), as shown in Figure 3.

Fig. 4 is the front view of crank (24), its front portion have individual quadrangular chamber (23) can with the supporting use of quadrangular (3) on moving gear (4) axle, Fig. 5 can be fixed on lock body on the vehicle bridge with it for the fixing pincers of " U " shape of lock.

During use, open locking closure (1) earlier, rotate moving gear (4) with crank (24) sleeve column quadrangular (3), make it drive driven gear (18) and make overbolt (7) rotation drive crank arm (14) and stretch out the sleeve pipe of cranking arm (15), and make the lock bridge chamber (21) of (14) front end of cranking arm pass the wheel hub bore, with pulling out " O " shape lock bridge (13) to the end, be that axle turn 90 degrees the angle again with the pin, the inner alignment pin of lock bridge pit (27) is ordered the crank (24) that rewinds again after (20), till making crank arm (14) retreat and strain to make " O " shape lock bridge (13) stiff, take off crank (24) and lock locking closure (1).

In the specific implementation, also this lock can be used in pairs, can pin the four-wheel of automobile like this, power passes to another lock by steel rope (9) from a lock, also can finish for twice with crank (24) operation.
