Abstract
The utility model belongs to the technical field of anti-theft locks with a tubular lock body and a long lock beam. The end of a lock bolt (4) can be rotatablely sheathed on the cylindric surface of a lock core (6), the poking piece (1) of the lock bolt (4) is engaged with the flat tenon end of the lock core (6), a spring (7) capable of resetting the lock bolt (4) is arranged between the lock bolt (4) and a lock housing (10), and an anti-poking sleeve (14) is arranged at the end of a long bolt beam (13) to form a step. Once the long lock beam enters into a lock hole (5), the long lock beam can be automatic locked by the lock bolt (4) without rotating a key (12). The lock hole (5) can be covered by the step which is formed by the anti-drawing sleeve (14), so that the lock bolt (4) can not be poked by a thin piece tool.
Description
The utility model belongs to the technical field of tubular lock body long lock beam theftproof lock.
The long lock beam theftproof lock that is used for the tubular lock body formula on motorcycle, the bicycle at present, its locking system all is that the flat tenon of the oblong aperture of lock bolt end and core end is engaged togather generally.Close when lock, need twist key earlier, make lock bolt be in the enable possition, then long lock beam is inserted in the keyhole on the tubular lock body, oppositely twist key again and make the lock bolt locking.The weak point of above-mentioned technology is operation inconvenience.
The purpose of this utility model is to provide a kind of lock that closes the time need not twist key, the lock bolt locking that just can automatically reset, and can prevent certainly the reset pick-proof lock locking apparatus of burglar with thin slice class instrument sled group lock bolt.
The purpose of this utility model is to realize like this, the lock bolt end is sleeved on the face of cylinder of core rotationally, the plectrum that drives lock bolt is connected with the flat tenon end of core, and the torsion spring that lock bolt is resetted is installed between lock bolt and the lock housing, and anti-dial sleeve is located at the long lock beam end and forms step.Plectrum unidirectional drive lock bolt is opened, and torsion spring forces lock bolt to reset, and after the step that anti-dial sleeve forms covered keyhole, the thin slice instrument can not be prized and dial lock bolt.The sidewall of lock bolt is made tile shape.The circular hole at center, end becomes matched in clearance with the cylinder of core end.Two hanging feets of torsion spring, a radially bending, a bending vertically.Plectrum is made the disc of band lug, and the oblong aperture at its center is slightly larger than the flat tenon of core end.Anti-dial sleeve is made the thin-walled short steel pipes, and its internal diameter becomes interference fits with the external diameter of long lock beam, is crimped in the pre-drilled heavy nest in long lock beam end.
The advantage that the utility model compared with prior art has is: because lock bolt is to be sleeved on rotationally on the core, torsion spring forces lock bolt to be in constant locked position, and after in a single day the lock hook on the lock bridge entered keyhole, lock bolt promptly can be automatically with its locking, the clockwise key that need not reverse just can be quickly with on sealed.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 2.
The tile shape sidewall external diameter of lock bolt (4) is slightly less than the internal diameter of tubular lock body (11), the outside, end has sector notch (19), the aperture of center hole (20) is slightly larger than the external diameter of core (6), is sleeved on the step end that core (6) and lock housing (10) form.The key of core (6) can be in-line, cross or cylindrical etc., but its external surface is the end the cylindrical of flat tenon or cylinder step are arranged, after being installed in the lock housing (10), the length that the inner exceeds is can install lock bolt (4), torsion spring (7), plectrum (1) and cottor pin (3) for suitable.The external diameter of torsion spring (7) is slightly less than the internal diameter of lock bolt (4) tile shape sidewall, and radially bending of hanging feet (2) is colluded on the tile shape sidewall of lock bolt (4), and hanging feet (8) bending is vertically inserted in the vertical core (9) in lock housing (10) outside.The circular diameter partly of plectrum (1) is slightly less than the internal diameter of lock bolt (4) tile shape sidewall; Lug radius partly is slightly less than or equals the outer radius of lock bolt (4) tile shape sidewall; The oblong aperture at center (16) becomes matched in clearance with the flat tenon of core (6) end, and flat tenon end is drilled with the cross-drilled hole of dress cottor pin (3).Lock bolt (4) torsion spring (7), plectrum (1) is sleeved on after core (6) and lock housing (10) go up successively, inserts cottor pin (3), has just limited the axially-movable of above-mentioned part, at this moment.Lock bolt (4) must overcome the elastic force of torsion spring (7), could rotate in sector notch (19) restricted portion.The sphere taper shape is made in the end of lock bridge (13), and a side has the lock hook (15) of breach shape, and the both sides of close lock hook (15) are drilled with dark about 1～1.5 heavy nest (18).After lock bridge (13) puts protection sebific duct (17), put anti-dial sleeve (14) again, make its end and lock hook (15) keep suitable distance, the metal stamping of anti-dial sleeve (14) is advanced in the heavy nest (18) in the top of heavy nest (18) with pin punch then, will prevent that dial sleeve (14) and lock bridge (13) are riveted together.The external diameter of lock housing (10) becomes interference fits with the internal diameter of tubular lock body (11), when the lock housing (10) that core (6), lock bolt (4), torsion spring (7), plectrum (1), cottor pin (3) are housed is packed into tubular lock body (11), should make lock bolt (5) block 1/3～3/8 of keyhole diameter, with alignment pin that lock housing (10) and tubular lock body (11) is fixing then.Close when lock, after the sphere conical end of lock bridge (13) enters keyhole (5), push open by the lock bolt (4) of torsion spring (7) compressing, when lock hook (15) when entering the lock position, lock bolt (4) reset and fastening in the breach of lock hook (15).When unblanking, twist core (6) with key (12), drive plectrum (1), overcome the elastic force of torsion spring (7), make lock bolt go to the enable possition, lock bridge (13) just can take off from keyhole (5).
