Description

Technical Field

[0001] This utility model relates to the field of explosion-proof junction box technology, specifically to an explosion-proof junction box fixing bracket. Background Technology

[0002] Explosion-proof junction box mounting brackets are devices specifically designed for the stable installation and fixation of explosion-proof junction boxes in flammable and explosive hazardous environments.

[0003] Currently, in existing technologies, explosion-proof junction box brackets do not have corresponding auxiliary positioning mechanisms when fixed to the wall. Due to the difficulty in achieving perfect uniformity in the flatness and verticality of the wall mounting surface, and the lack of precise guidance and temporary fixing methods when construction personnel manually align the bracket mounting holes with the wall anchor points, problems such as bracket installation angle deviation and inaccurate hole alignment are very likely to occur. This results in the bracket being subjected to uneven stress over a long period of time, accelerating loosening and deformation under vibration, impact, and other working conditions, thereby weakening the stability and reliability of the explosion-proof system. In view of this, we propose an explosion-proof junction box fixing bracket. Utility Model Content

[0004] The main objective of this invention is to provide an explosion-proof junction box fixing bracket that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes an explosion-proof junction box fixing bracket, including a wall, a round rod fixedly connected to the wall, a bracket installed on the wall, an explosion-proof junction box installed on the bracket, and an installation mechanism provided on the wall, the installation mechanism including a sliding groove, the sliding groove being provided on the side wall of the wall.

[0006] Preferably, the slide is slidably connected to a movable plate, the side wall of the movable plate is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to a handle.

[0007] Preferably, a connecting block is fixedly connected to the end of the rotating shaft away from the handle, a plug rod is fixedly connected to one end of the connecting block, a connecting rod is fixedly connected to the other end of the connecting block, and a circular plate is fixedly connected to the end of the connecting rod away from the connecting block.

[0008] Preferably, the side wall of the bracket is rotatably connected to a second connecting block, and the side wall of the second connecting block is provided with an insertion hole.

[0009] Preferably, the bracket has a movable groove, a spring is fixedly connected to the inner wall of the movable groove, a movable plate is fixedly connected to the end of the spring away from the inner wall of the movable groove, and the movable plate is slidably connected to the movable groove.

[0010] Preferably, the movable slot is provided with a through groove, and an auxiliary rod is slidably connected to the through groove. The auxiliary rod is fixedly connected to the movable plate, and the side wall of the movable plate is provided with a groove. The auxiliary rod is pushed backward through the through groove, thereby driving the movable plate to move into the movable slot. At this time, the movable plate is moved towards the bracket through the sliding groove. At this time, the plug on the first connecting block will be inserted into the plug hole on the second connecting block. Then, the handle is turned, which drives the rotating shaft to rotate. The rotation of the rotating shaft will drive the first connecting block to rotate, thereby driving the second connecting block to rotate as well. The handle is rotated 90 degrees, so that the connecting rod and the circular plate also rotate 90 degrees together. At this time, the auxiliary rod is released, and the movable plate will be elastically reset under the elastic restoring action of the spring, so that the groove on the movable plate is engaged with the connecting rod, thereby completing the auxiliary positioning of the bracket and making the installation of the explosion-proof junction box more stable.

[0011] Preferably, the bracket is provided with fixing holes and round holes respectively.

[0012] This utility model provides an explosion-proof junction box mounting bracket. It has the following beneficial effects:

[0013] (1) The explosion-proof junction box fixing bracket uses a through groove to push the auxiliary rod backward, thereby driving the movable plate to move into the movable groove. At this time, the sliding groove moves the movable plate towards the bracket. At this time, the plug on the first connecting block will be inserted into the plug hole on the second connecting block. Then, turn the handle to drive the rotating shaft to rotate. The rotation of the rotating shaft will drive the first connecting block to rotate, thereby driving the second connecting block to rotate as well. Turn the handle 90 degrees, so that the connecting rod and the circular plate will also rotate 90 degrees together. At this time, release the auxiliary rod. Under the elastic reset action of the spring, the movable plate will be driven to elastically reset, so that the groove on the movable plate will engage with the connecting rod, thereby completing the auxiliary positioning of the bracket and making the installation of the explosion-proof junction box more stable.

[0014] (2) The explosion-proof junction box fixing bracket connects the first connecting block and the second connecting block by using a plug rod. When the connecting rod is limited by the groove, the position of the first connecting block is limited, which in turn constrains the position of the second connecting block, and finally makes the position of the bracket stable and fixed.
