Description

Technical Field

[0001] The utility model belongs to the technical field of explosion-proof box installation, in particular to an explosion-proof box fixed installation bracket. Background Art

[0002] An explosion-proof box is an explosion-proof device used to install electrical equipment or connect cables. It is usually used in explosive gas environments or flammable dust environments to prevent sparks or arcs from causing explosions in the equipment.

[0003] The existing explosion-proof box installation usually first installs it and the cable, and then fixes the explosion-proof box on the bracket. During the fixing process, there is an offset between the mounting platform and the explosion-proof box. If forced installation is required, it will cause the cable to tilt at a large angle, causing the cable to twist, affecting the service life of the cable. For this reason, we provide a fixed installation bracket for the explosion-proof box. Utility Model Content

[0014] 1. The utility model sets a mounting platform, and the pull rod drives the connecting rod to move to the right side. When the connecting rod moves to the right side, it drives the rotating block to move synchronously and stretches the spring. When the rotating block moves to the right side, it pulls the support rod inward. When the support rod is pulled, it drives the card block to move closer to the mounting platform, so that the card block is separated from the card slot, and then the mounting platform is moved to the bottom of the explosion-proof box, so that the explosion-proof box can be installed on the turntable. It can also prevent the cable from being twisted due to position deviation when installing the cable and the explosion-proof box, and the cable needs to be bent for installation, which affects the service life of the cable.

[0015] 2. The utility model connects the explosion-proof box with the cable by setting a turntable, and then places the explosion-proof box on the turntable and fixes it with a clamping plate.
