Abstract

The invention discloses a four-arm linkage locking mechanism, which belongs to the technical field of production equipment for thermal insulation composite plates of refrigerated vehicles, and aims to solve the problem of low automation of existing equipment. It includes a turntable, the turntable is fixed to the upper mold through a fixed pin, and a cylinder is installed beside the turntable, the piston rod of the cylinder is connected with the turntable, and a pair of connecting rods five arranged horizontally are connected to the turntable, and the connecting rod five is connected to the turntable through a connecting pin. , the other end of connecting rod five is connected to connecting rod one and connecting rod two through a movable connecting pin, the other end of connecting rod one is connected to the upper mold through a fixed pin, and the other end of connecting rod two is connected to connecting rod three through a movable connecting pin And connecting rod 4, the other end of connecting rod 3 is connected to the upper mold through a fixed pin, a sliding groove is opened on the connecting rod 4, a sliding pin is arranged in the sliding groove, and a hook is also arranged, and the lower part of the hook is fixed by a bolt and a nut In the lower mold, the upper part of the hook is engaged with the four connecting rods. The invention is suitable for a four-arm linkage locking mechanism.

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...
