Description

Junction of the edges of two sheets of paper lock and key thereof

The utility model relates to a kind of lock, especially a kind of bicycle or motor Vehicle lock, and supporting with it key.

Existing in the market bicycle lock or motorcycle all exist various deficiencies, and be hard to guard against to the car thief.Someone has proposed a kind of U type padlock is greatly improved the performance of lock, and this lock generally all curves the U-shape lock ring with alloy bar, and lock ring passes after the vehicle wheel spoke, inserts two apertures on the locking bar, locks then.The lock gall of this lock is still the same with common lock with snap, pounds so can not prevent hammer, can not prevent master key, and the tension degree is also not enough.

The purpose of this utility model provides a kind of bicycle or motor Vehicle lock, and supporting with it key, can pick-proof, anti-drilling, anti-saw, and again can be in case hammer is pounded, anti-master key.

For achieving the above object, the scheme that the utility model provides is: a kind of junction of the edges of two sheets of paper lock, by the U-shape lock ring, locking bar, the lock gall marble sleeve, lock gall and lock pin are formed, it is characterized in that locking bar is divided into inserted link and tapered end two parts, inserted link can pass the hole of the hole insertion other end of U-shape lock ring one end, and with the hole of the other end be threaded engagement, have the hole of a band groove on the tapered end, just can hold the lock gall marble sleeve, and the hole extends on inserted link and the lock ring, respectively form a groove on the two surface, in the lock gall marble sleeve lock gall is housed, lock gall and lock pin are connected as a single entity, lock pin is positioned at the groove on inserted link and the lock ring during locking, with the lock gall joint one fixture block is being arranged, when fixture block alignd with the groove of circular-hole internal-wall, lock pin can be extracted outside the hole; The key hole of lock gall is V-shape.

Phase-locked corresponding with the junction of the edges of two sheets of paper, the utility model gives a kind of key, and the section of tooth portion is V-shaped, and matches with the key hole of the described junction of the edges of two sheets of paper lock of claim 1.

The such scheme effect is, lock gall and pin pin are connected as a single entity, stride across the slit between tapered end and lock gall, the two is coupled together reliably, and lock pin is that carbide alloy is made, can be anti-drilling, even boring mashed lock gall also can't unblank, locking bar and lock ring are connected as a single entity, and lock gall is ensconced in the locking bar, makes this lock have no way of levering up.Because can preventing hammer well, the fixture block on the lock pin, lock pound.Make lock be difficult to cut through heat treated surface.In addition, the key hole of V-type can avoid master key to unblank.

Further specify below in conjunction with embodiment and accompanying drawing.

Embodiment: lock ring 1 is the U type, be drilled with the hole locking bar on two end faces and be divided into inserted link 2 and tapered end 3 two parts, inserted link can pass the hole of U-shape lock ring one end, insert the hole of the other end, the diameter of tapered end 3 is about the twice of inserted link 2, the midpoint of vertical radius is that a hole 4 has been punched in the center of circle on tapered end top, a groove 5 is arranged in the hole, and extend on inserted link 2 and the tapered end 3, the two just respectively has a groove separately the time when inserted link 2 and tapered end 3, lock gall marble sleeve 6 is positioned at the hole, and in cover, lock gall 7 is housed, lock gall 7 and lock pin 8 are connected as a single entity by machine, lock pin 8 is made for carbide alloy, during locking junction of the edges of two sheets of paper lock, lock pin 8 is positioned at the groove on inserted link 2 and the tapered end 3, with the lock gall joint one fixture block 9 is arranged, when fixture block 9 alignd with hole inner groovy 5, lock gall 7 and lock gall marble sleeve 6 can be extracted in the hole, the key hole of lock gall 7 is V-shape, the key 10 tooth portion sections supporting with it also are V-shape, insert key 10 and rotation during use, and lock gall together rotates thereupon, the groove 5 outer keys that draw of fixture block 9 alignment holes, lock gall 7 and lock pin 8 outer moving, the rotation tapered end just can be extracted inserted link.In the time will locking junction of the edges of two sheets of paper lock, reverse rotation tapered end, inserted link insert in the hole of lock ring, when rotating to inner end, advance lock pin and lock gall by key, make lock pin be positioned at groove on lock ring and the inserted link, screw key again, fixture block blocks the lock gall marble sleeve, extracts key then and gets final product.

Fixture block 9 and groove 5 just in time align when advancing lock pin and lock gall in order to make, and on tapered end and face that lock ring contacts a projection are arranged respectively, when fixture block 9 and two projections of 5 pairs of timings of groove just prop up mutually and can play the role of positioning.
