Abstract

The utility model discloses a lock, in particular to a U-shaped lock, which comprises a lock body, a lock cylinder, a U-shaped lock bow (3) and a lock beam (4), wherein the lock body (1) is a cavity metal tube shell (5), and the lock cylinder (2) and a fastener (6) are connected together by a lock catch (7) and then mounted in the shell (5). By adopting the technical scheme, the U-shaped lock has the advantages of convenience in use, time and labor economization, prolonged service life of the lock cylinder and the like.

Description

U-shape lock

Technical field

The utility model relates to a kind of lock, specifically is a kind of U-shape lock.

Background technology

U-shape lock in the market, its lock body structure more complicated, lock body cavity inside and lock bridge are the helicitic texture that cooperatively interacts, in order to reach sealed purpose, need twist a lot of circles of key rotation, make lock core increase wearing and tearing, the application life that has shortened lock core is not only time-consuming but also inconvenient.

Summary of the invention

In order to address the above problem, a kind of U-shape lock that the utility model provides has conveniently, the timesaving effect.

In order to achieve the above object, a kind of U-shape lock of the present utility model comprises lock body, lock core, U-shape lock bow and lock bridge, and described lock body is a cavity metal tube shell, and lock core and buckle link together by snap close, are installed in the shell then.

Described buckle is the cavity cylinder, and one end and snap close weld together, and the other end is provided with a rectangular opening.

Described snap close is the middle round iron plate that is provided with slot, and slot matches with lock core (2) one end projectioies in the middle of the snap close.

Described U-shape lock bends an end fixedlys connected with shell, and the other end and cavity metal short tube are fixed together.

Described lock bridge is the solid metal that end both sides have projection, and described solid metal cooperates with the cavity metal short tube of the U-shape lock bow other end.

Described shell with the sealed end of lock bridge inward flange is set, and be provided with on the inward flange with lock bridge one end on the protruding groove that matches.

The specific embodiment:

Extremely shown in Figure 6 by Fig. 1, a kind of lock body, lock core 2, U-shape lock bow 3 and lock bridge 4 of comprising, described lock body is a cavity metal tube shell 5, lock core 2 and buckle 6 link together by snap close 7, are installed in then in the shell 5; Buckle 6 is the cavity cylinder, and one end and snap close 7 weld together, and the other end is provided with a hole 8; Snap close 7 is the middle round iron plate that is provided with rectangular opening, matches with protruding 14 of lock core 2 one ends in snap close intermediate rectangular hole; U-shape lock bends 3 one ends fixedlys connected with shell 5, and the other end and cavity metal short tube 12 are fixed together; Lock bridge 4 is the solid metal that end both sides have projection 10, and described solid metal cooperates with the cavity metal short tube 12 that U-shape lock bends 3 other ends; Shell 5 with the sealed end of lock bridge 4 inward flange is set, and be provided with on the inward flange with lock bridge 4 one ends on protruding 10 grooves 11 that match.

When sealed, insert in the lockhole 15 with key and to rotate, rotary locking cylinder 2, the projection 14 by lock core 2 one ends drives buckles 6 whole rotations, and when hole 8, projection 10 were corresponding with groove 11 threes, external force pushed lock bridge 4, and screw key is realized sealed.

When unblanking, screw key makes hole 8, projection 10 when corresponding with groove 11 threes, and external force is extracted lock bridge 4, realizes unblanking.
