Problems solved by technology

[0002] The boxes used for opening and closing on the market usually include an upper box cover and a lower box cover, and a lock is arranged between the upper box cover and the lower box cover. The place where the lock is used for manual operation is usually a straight structure. The force arm of the straight structure is relatively short. In order to ensure that the lock is not easily damaged, the length of the lock is longer. For thinner suitcases, the lock limits the thickness of the box

Embodiment Construction

[0017] refer to figure 1 -3. An embodiment of the present invention provides a buckle with an increased force arm, including a hinge part 100, a locking part 200 and a handle part 300. The hinge part 100 is hinged to the upper box or the lower box, so The locking part 200 is connected to the hinge part 100 and snapped on the other half of the box body to lock and close the upper box body and the lower box body. The handle part 300 is connected to the locking part 200 and the handle part 300 The ends are bent away from the surface of the box.

[0018] In this embodiment, the handle portion 300 is required to be inclined, so that the length of the handle portion 300 can be correspondingly increased in a limited space or the thickness of the box body can be reduced with the same arm length, so the corresponding hinge portion The structures of the 100 and the locking part 200 can be implemented in various ways.

[0019] The hinge part 100 includes three cylindrical hinge shafts ...

Abstract

The invention discloses a lock catch capable of lengthening a force arm, and a tank thereof. The lock catch comprises a hinge-joint part, a locking part and a lifting handle part, wherein the hinge-joint part is hinged with an upper tank or a lower tank; the locking part is connected with the hinge-joint part and is connected onto the other half tank in a clamping way, so that the upper tank and the lower tank are locked and closed; the lifting handle part is connected with the locking part; and the tail end of the lifting handle part is bent toward the direction far away from the surface of the tank. The lifting handle part is inclined upwards, and the lifting handle part can be set to be longer in a straight space on which an original lifting handle part is arranged, so that the lock catch can be opened easily correspondingly, and the thickness of the tank can be set to be thinner.

Description

technical field [0001] The invention relates to a lock buckle for a box, in particular to a lock buckle with an increased force arm and a box body thereof. Background technique [0002] The boxes used for opening and closing on the market usually include an upper box cover and a lower box cover, and a lock is arranged between the upper box cover and the lower box cover. The place where the lock is used for manual operation is usually a straight structure. The moment arm of the straight structure is relatively short. In order to ensure that the lock is not easy to damage, the length of the lock is longer. For thinner suitcases, the lock limits the thickness of the casing. Contents of the invention [0003] In order to solve the above problems, the present invention provides a lock with increased force arm and its box, which has an arc-shaped handle, which is equivalent to increasing the force arm when opening the lock, so that the lock saves more space. [0004] The techni...
