Abstract

The invention discloses a four-arm-linkage locking mechanism, belongs to the technical field of production equipment for heat preservation composite boards of refrigerator cars, and aims at solving the problem that existing equipment is low in automation degree. The device comprises a rotary disc, wherein the rotary disc is fixed to an upper die through a fixing pin, an air cylinder is further installed beside the rotary disc, a piston rod of the air cylinder is connected with the rotary disc, a pair of horizontally-arranged fifth connecting rods are connected to the rotary disc through connecting pins, a first connecting rod and a second connecting rod are connected to the other ends of the fifth connecting rods through movable connecting pins, the other end of the first connecting rod isconnected to the upper die through a fixing pin, the other end of the second connecting rod is connected with a third connecting rod and a fourth connecting rod through movable connecting pins, the other end of the third connecting rod is connected to the upper die through a fixing pin, a sliding groove is formed in the fourth connecting rod, a sliding pin is arranged in the sliding groove, and aclamping hook is further arranged with the lower part fixed to a lower die through a bolt and a nut, and the upper part clamped to the fourth connecting rod. The four-arm-linkage locking mechanism isdisclosed.

Description

technical field [0001] The invention belongs to the technical field of production equipment for thermal insulation composite plates of refrigerated vehicles, and in particular relates to a four-arm linkage locking mechanism. Background technique [0002] At present, most of the production equipment of the traditional bonding process adopts a heated positive pressure hydraulic bed or a normal temperature negative pressure press through pressurization, heating and bonding. The principle and structure of these two types of equipment are relatively simple, the degree of automation is very low, and the corresponding production process is complex and not environmentally friendly; the closed foam production equipment is generally composed of a high-pressure foaming unit and a rotatable combined mold. The principle and structure of this kind of equipment are relatively simple, the degree of automation is low, and the corresponding production process has a great conflict with the phy...
