Abstract

Locks, for example locks for bicycles. The lock has a lock body made into an open ring-shaped integral structure with high strength by a simple method, and when the lock is locked, both ends of a section of the lock tongue outside the lock body are limited along the axial direction and the radial direction, so that the lock body is difficult to separate and deform, the lock tongue is difficult to deform and slide out from the locking position when stressed, and the lock is firm and has good prying resistance and folding resistance.

Description

Lock

The invention relates to and constitute by the integrally-built lock body of opening ring-type.When locking, one section outer dead bolt two ends of lock body all have vertically and spacing lock radially, are the inventions of bicycle lock.

Overall structure of the present invention is meant that integral body is that structure or the integral body that is made of intermolecular combination is in conjunction with the structure that constitutes by mutual infiltration mode between tissue.

Bicycle lock always, its lock body is after being shaped by two metal stampings, make with metal rivet riveted on limited point, pried open from seam crossing easily, and, the lock body that is made of two metal riveteds is also easily by bending, its dead bolt has end infinite place vertically in the lock body, when lock body and dead bolt stress deformation, an end of infinite place skids off in the lock body easily, theftproof performance is not good, and bicycle is stolen by sled easily.

It is stolen behind locking that the inventor suffers from repeatedly bicycle, through conscientiously research, finished the present invention finally.

The objective of the invention is in order to provide a kind of behind locking firmer, pick-proof and the good lock of fracture resistance.

Lock body of the present invention is preferably: with metal material, select for use tubing section bar, cross section be circular, make with bending machining, also can make, but lock body and also be fine certainly if make with other overall structure with several metal parts welding.

The present invention finishes as follows: select the material with higher-strength index and excellent machinability for use, with dead bolt and lock body mould, anchor clamps are processed into dead bolt and have the opening ring-type in identical middle footpath with lock body cavity, the lock body has overall structure, the dead bolt head is processed into shoulder, select the tapered end that has with the corresponding latch-up structure of dead bolt head shoulder shape for use, the end that tapered end links to each other with the lock body is processed into and locks the corresponding shape of body cavity, preferably be processed into the tight fit structure, and respectively process an aperture of hanging spring at this end and dead bolt afterbody, both ends of the spring is hung in the aperture of tapered end and dead bolt afterbody, again tapered end one end is stretched in the lock body cavity and fix, with usual way handle is fixed with dead bolt in the handle sliding tray then with usual way and lock body.Be fixed on the handle on the dead bolt, when the dead bolt locking, should press close to close dead bolt head one end at the handle sliding tray.When needing, also available dead bolt afterbody obtains the mode of holding power from lock body or lock head, and dead bolt is strengthened.

The present invention will lock body and make an opening ring-type overall structure that intensity is higher, make the separation and the distortion of lock body very difficult, during locking, dead bolt passes through tapered end by handle, dead bolt head, suffered power can be passed to the lock body, and obtain holding power, make dead bolt when stressed from the lock body, be difficult to be out of shape and skid off, can realize the requirement that pick-proof is stolen from locked position.

With reference to the accompanying drawings lock of the present invention is described in detail below.Accompanying drawing is the partial sectional view after two positions are dissectd on one's body to lock of the present invention.

Tapered end (1) has the corresponding latch-up structure of shoulder shape with dead bolt head (8), the end that tapered end (1) links to each other with lock body (2) is processed into and locks the corresponding shape of body (2) cavity, and stretch in lock body (2) cavity, stretching on end of lock body (2) cavity and the dead bolt afterbody (4) at tapered end (1) all has aperture, the two ends of spring (3) hang in the above-mentioned aperture, tapered end (1) is fixing with usual method and lock body (2), dead bolt (5) is processed into the opening ring-type with identical middle footpath with the cavity of lock body (2), handle (6) stretches in the handle sliding tray (7), be fixed on the appointed part of dead bolt (5) with usual method, make that handle (6) should be pressed close to the end at the close dead bolt head (8) of handle sliding tray (7) when dead bolt (5) stretches into tapered end (1) locking.In addition, the shoulder shape of dead bolt head (8) is the hemispherical shoulder in the accompanying drawings, also can be made into conical shoulder, if but the shoulder of other shape also is fine certainly.Tapered end (1) is an axis and the column of lock body (2) dead in line in the accompanying drawings, if but other shape also is fine certainly, for example to tapered end (1) extend, tapered end (1) is made of orthogonal two columns etc.

Above-mentioned tapered end (1) and the most handy welding of fixing means of locking body (2), handle (6) and dead bolt (5), but if also be fine certainly with other common fixing means.
