Abstract
The utility model relates to an explosion-proof mechanism of explosion-proof switch, including shell body flange (1) and door closure flange (5), its characterized in that: two shell body pressing blocks (4) are arranged on two sides of a shell body flange (1) respectively, two door cover pressing blocks (6) are arranged on two sides of a door cover flange (5) respectively, a clamping groove (8) is fixed to the upper end of the shell body flange (1), a clamping groove (8) is fixed to the lower end of the door cover flange (5), the shell body flange (1) and the door cover flange (5) are correspondingly buckled together through the clamping groove (8) and fixed through an adjusting bolt (7), and the shell body pressing blocks (4) of the door cover pressing blocks (6) are overlapped. The gap between the explosion-proof junction surfaces of the shell body flange and the door cover flange is ensured, and the national standard requirement of the explosion-proof product industry is met.
Description
Technical Field
The utility model belongs to a colliery is explosion-proof switch for in pit, concretely relates to explosion-proof mechanism of quick-opening door type explosion-proof switch.
Background
The explosion-proof switch used in the underground of the coal mine is basically of a quick-opening door type structure at present, but the explosion-proof mode of a flange surface is various, and most common explosion-proof switches comprise a pressing block, a retaining screw, a stop strip, a clamping hook and the like. Some machining processes are complex, some machining processes have high requirements on machining precision, and some machining processes are too many.
Disclosure of Invention
The utility model discloses just eliminate above-mentioned prior art not enough and defect, provide an explosion-proof mechanism of explosion-proof switch that processing is simple, reliable performance is high.
In order to achieve the purpose, the utility model adopts the technical proposal that: the utility model provides an explosion-proof mechanism of explosion-proof switch, includes shell body flange and door closure flange, its characterized in that: two sides of the shell body flange are respectively provided with two shell body pressing blocks, two sides of the door cover flange are respectively provided with two door cover pressing blocks, the upper end of the shell body flange is fixedly provided with a clamping groove, the lower end of the door cover flange is fixedly provided with a clamping groove, the shell body flange and the door cover flange are correspondingly buckled together through the clamping grooves and are fixed through adjusting bolts, and the door cover pressing blocks are overlapped with the shell body pressing blocks.
The shell body pressing block is fixed with the shell body flange through a fixing bolt and an elastic washer; the door cover pressing block is fixed with the door cover flange through a fixing bolt and an elastic washer.
The principle is as follows: the two sides of the shell flange are overlapped through two pressing blocks fixed on the two sides of the shell body flange and two pressing blocks on the two sides of the door cover flange to ensure the clearance of the flange joint surface; the upper end and the lower end of the shell flange are respectively limited by the clamping grooves to ensure the clearance of the flange joint surface.
The utility model has the advantages that: the gap between the explosion-proof junction surfaces of the shell body flange and the door cover flange is ensured, so that the value range of the explosion-proof junction surface meets the national standard requirement of the explosion-proof product industry; meanwhile, the thickness of the shell body flange and the door cover flange is reduced, and the material cost can be saved by 15-20%. The mechanism is simple and flexible; the processing is convenient and efficient; the reliability is good.
