Abstract

The invention provides a refrigerator box body foaming and locking mechanism. The box body foaming and locking mechanism comprises a base, a bent lever body, a safety hook body, a lock seat and a safety hook limiting block, wherein the base is provided with a bracket; the bracket is provided with the bent lever body which can rotate freely around a bent lever; one end of the bent lever body is straight and the other end of the bent lever is hook-shaped; one hook-shaped end of the bent lever body is contacted with the lock seat; the safety hook limiting block matched with the safety hook body is arranged on the bent lever body between a shaft hole of the bent lever and the straight end part of the bent lever body; one straight end, which is close to the bent lever body, of the safety hook body, is a straight rod, and the other end of the safety hook body is a right-angle hook; when the locking mechanism is at a locked state, an included angle between the one straight rod end of the safety hook body and one straight end of the bent lever body is an acute angle; a hook tip matched with a lock block is arranged at the right-angle hook end part of the safety hook. According to the refrigerator box body foaming and locking mechanism provided by the invention, the safety hook is used for preventing the bent rod from falling off so as to effectively prevent the locking mechanism from losing efficacy; the refrigerator box body foaming and locking mechanism is simple in structure and can be operated by a single hand.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a foaming locking mechanism for a refrigerator box. Background technique [0002] At present, during the foaming process of the box body, the locking mechanism usually adopts an unsecured locking mechanism. During production, it is very easy to cause the locking mechanism to fail due to the extrusion force during foaming, thereby causing injury to personnel and reducing the qualified rate of the product. Contents of the invention [0003] In order to solve the shortcomings of the existing locking mechanism of the box foaming mold, such as complex structure, inconvenient operation and no safety function, the present invention provides a foaming locking mechanism for the refrigerator box. [0004] The technical solution adopted by the present invention to solve the technical problem is: the foam locking mechanism of the refrigerator box includes a base, a curved rod body, a safety hook body...
