DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a gas pressure balancing device that is easy to repair, including a gas pressure balancing device body 1, a conduit 2 is fixedly installed on the right side of the gas pressure balancing device body 1, a pressure gauge 3 is fixedly installed on the top of the gas pressure balancing device body 1, a cover plate 4 is arranged on the top of the gas pressure balancing device body 1, and a fixed component 5 and a movable component 6 are arranged on the surface of the gas pressure balancing device body 1. When the slide bar 63 slides, it will drive the clamping plate 66 and the clamping block 67 to move to the surface away from the cover plate 4, thereby releasing the restriction on the cover plate 4 and carrying out repair. When the repair is completed and it needs to be installed, the cover plate 4 can be plugged into the inside of the gas pressure balancing device body 1, and the control plate 68 can be pressed in the reverse direction to drive the clamping block 67 to move to the surface close to the cover plate 4, so as to fix it, and the movable component 6 includes: a fixed ring 61, a rotating ring 62, a slide bar 63, a movable bar 64, a fixed block 65, a clamping plate 66, a clamping block 67, and a control plate 68.

[0024] A fixed ring 61 is fixedly installed on the top of the air pressure balancing device body 1, a swivel ring 62 is rotatably connected inside the fixed ring 61, a slide rod 63 is slidably connected inside the swivel ring 62, a movable rod 64 is fixedly installed on the outside of the slide rod 63, a fixed block 65 is provided on the surface of the movable rod 64, the fixed block 65 is fixedly installed on the inner side of the fixed ring 61, the movable rod 64 passes through the fixed block 65, a clamping plate 66 is fixedly installed on the surface of the movable rod 64, a clamping block 67 is fixedly installed on the inner side of the clamping plate 66, and a control panel 68 is fixedly installed on the surface of the swivel ring 62, thereby improving the convenience and work efficiency of maintenance of the air pressure balancing device body 1.

[0025] The fixing assembly 5 includes: a positioning ring 51, which is fixedly mounted on the top of the cover plate 4, a plug block 52 is fixedly mounted on the top of the clamping plate 66, a positioning block 53 is hinged on the surface of the plug block 52, and a volute spring 54 is fixedly mounted on the surface of the positioning block 53. When the clamping plate 66 moves toward the surface close to the cover plate 4, the plug block 52 and the positioning block 53 are also driven to move in the same moving direction as the clamping block 67. When the positioning block 53 moves, it will penetrate the positioning ring 51. When the positioning ring 51 and the positioning block 53 penetrate, the positioning block 53 will contact the surface of the cover plate 4 and The bottom of the swivel 62 is swung downward, so that it is clamped on the inner side of the positioning ring 51 for fixation, which improves the stability and fixing effect when the air pressure balancing device body 1 is connected to the cover plate 4. An arc groove 620 is provided on the surface of the swivel 62, and the rotation of the swivel 62 can drive the sliding of the slide bar 63. The cross-section of the clamping plate 66 is L-shaped, which can improve the connection effect between the clamping plate 66 and the clamping block 67. The cross-section of the clamping block 67 is arc-shaped, which can improve the connection sealing between the clamping block 67 and the cover plate 4. A groove 510 is provided on the surface of the positioning ring 51, which can drive the positioning block 53 to penetrate the positioning ring 51.

[0026] When the air pressure balancing device body 1 needs to be inspected and maintained, the control panel 68 can be manually pressed to drive the swivel 62 to rotate inside the fixed ring 61. When the swivel 62 rotates, it will contact the slide bar 63 through the arc groove 620 opened on the surface of the swivel 62, and drive the slide bar 63 to move toward the surface away from the cover plate 4. When the slide bar 63 moves, it will drive the movable rod 64 to slide in the same moving direction of the slide bar 63. When the slide bar 63 slides, it will drive the clamping plate 66 and the clamping block 67 to move toward the surface away from the cover plate 4, thereby releasing the restriction on the cover plate 4 and carrying out maintenance. When installation is required after the maintenance is completed, the cover plate 4 can be plugged into the interior of the air pressure balancing device body 1, and the control panel 68 can be pressed in the reverse direction to drive the clamping block 67 to move toward the surface close to the cover plate 4, thereby fixing it, thereby improving the convenience and work efficiency of maintenance of the air pressure balancing device body 1.

[0027] When the clamping plate 66 moves toward the surface close to the cover plate 4, it will also drive the insert block 52 and the positioning block 53 to move in the same direction as the clamping block 67. When the positioning block 53 moves, it will penetrate the positioning ring 51. When the positioning block 53 penetrates the positioning ring 51, the positioning block 53 will come into contact with the surface of the cover plate 4 and swing downward at the bottom of the cover plate 4, thereby being clamped on the inner side of the positioning ring 51 for fixation, thereby improving the stability and fixing effect when the air pressure balancing device body 1 is connected to the cover plate 4.
