Abstract

The invention relates to the technical field of locking devices and discloses a container positive-negative-pressure locking device, wherein a negative-pressure locking mechanism and a positive-pressure locking mechanism are arranged on a fixed seat, the negative-pressure locking mechanism comprises a first cylinder which is installed on the fixed seat, a U-shaped connecting seat is arranged at the shaft end of the first cylinder on the fixed seat, both sides of the U-shaped connecting seat are respectively provided with a J-shaped guide hole, a clamping jaw is arranged in the U-shaped connecting seat, the clamping jaw is fixedly connected with the shaft end of the first cylinder, both sides of the clamping jaw are respectively provided with a guide pin, and both ends of the guide pin respectively extend into the J-shaped guide holes; the positive-pressure locking mechanism comprises a cylinder bracket which is installed on the fixed seat, a second cylinder is arranged on the cylinder bracket, the shaft end of the second cylinder is provided with a clamping block, the outer end of the clamping block is provided with a clamping opening, and the width of the open end of the clamping opening is greater than that of the bottom of the clamping opening. Therefore, the container positive-negative-pressure locking device has the beneficial effects of good convenience in locking and unlocking, stability in locking and more safety in use.

Description

technical field [0001] The invention relates to the technical field of locking devices, in particular to a container positive and negative pressure locking device. Background technique [0002] Nowadays, many experiments need to be carried out in a vacuum state. Some experiments need to use a large-volume vacuum container. The vacuum container generally includes a simple body and a cover. The container and the cover are connected by a flange. The container flange and the cover flange Lock between them with a locking device, and then vacuumize. After vacuuming, the interior of the container is in a negative pressure state. At this time, the locking mechanism is mainly to give a locking force to the cover flange before and at the beginning of vacuuming, and the container is vacuumed. In the final test, for example, when a certain substance is burned, the internal pressure of the container changes from negative pressure to positive pressure. For large containers, the pressure o...
