Embodiment Construction
[0009] In the accompanying drawings, an adjustable lock includes a lock hook 1 , a buckle 2 , a bottom plate 8 , a lock nose 7 and a wrench holder 6 .
[0010] As shown in the drawings, the locking nose 7 and the bottom plate 8 can be welded and fixed, or the locking nose 7 and the bottom plate 8 can be integrally stamped and formed. This embodiment preferably adopts the technical solution that the locking nose 7 and the bottom plate 8 are stamped and formed integrally. Lock nose 7 has keyhole 9.
[0011] A hinge seat 4 is stamped integrally on the base plate 8 .
[0012] In the accompanying drawings, the wrench frame 6 is in the shape of a fork, and is hinged on the hinge seat 4 by a hinge shaft. The wrench frame 6 can swing back and forth around the hinge shaft, and can be locked with the locking nose 7 when it is in the end position.
[0013] As shown in the accompanying drawings, a pin shaft 5 is assembled between the fork-shaped frame bodies of the wrench frame 6 .

The invention relates to an adjustable lock catch which comprises a lock hook, a retaining ring, a baseplate, a lock nose and a wrench frame, wherein the lock nose is fixedly connected with the baseplate, and the lock nose is provided with a lock hole. The adjustable lock catch is characterized in that a hinged support is arranged on the baseplate, the wrench frame is hinged on the hinged support in a forked shape, a hinge pin is assembled between forked frame bodies of the wrench frame, the retaining ring is fixedly connected with a draw bar, and the draw bar is in threaded connection with the hinge pin. Due to the threaded advance and retreat between the draw bar and the hinge pin, the connection length between the retaining ring and the lock hook can be adjusted conveniently; the retaining ring and the lock hook are in rigid connection with each other; and in the connection state, the connecting clearance is small, and the connection is firm. The adjustable lock catch disclosed by the invention is less in used parts, simple in structure and low in cost.
Description
technical field [0001] The invention relates to a buckle fastener, in particular to an adjustable buckle which can adjust the locking force of a connected object. Background technique [0002] We know that the connection of sheet metal parts or the connection of the hinged lid and the box body adopts a lock connection. Most of the snap connection adopts a rigid connection between the lock hook and the lock nose, and the assembly margin between the lock hook and the lock nose is small, so the requirement for the connection length is relatively strict. Since the connected objects are easily deformed during use, a connection gap is generated, resulting in an unstable connection. Numerous technicians have invented the snap close that can automatically adjust connection angle and length for this reason. For example, "a spring lock" disclosed in the CN2565922Y Chinese utility model patent specification authorized and announced on August 13, 2003 includes a hook, a base and a han...
