DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a hardware sealing device suitable for a high-pressure environment, comprising a fixing frame 1, a first fixing hole 2 is opened on the fixing frame 1, slide grooves 3 are opened on both sides of the fixing frame 1, a guide rod 4 is connected in the slide groove 3 on one side of the fixing frame 1, a threaded rod 5 is rotatably connected in the slide groove 3 on the other side of the fixing frame 1, a connecting block 6 is connected at one end of the threaded rod 5, a moving plate 7 is installed on the threaded rod 5, a rubber pad 20 is connected under the moving plate 7, connecting plates 21 are connected on both sides of the moving plate 7, the connecting plate 21 on one side of the moving plate 7 is threadedly connected to the threaded rod 5, and the connecting plate 21 on the other side of the moving plate 7 slides on the guide rod 4, and when the moving plate 7 moves down along the threaded rod 5, the connecting plate 21 at the other end of the moving plate 7 will slide on the guide rod 4, thereby guiding and restricting the movement of the moving plate 7 to prevent the moving plate 7 from tilting during movement.

[0023] A hardware pipe 8 is installed between the movable plate 7 and the fixed frame 1, and a sealing ring 9 is sleeved on the hardware pipe 8. An anti-slip pattern 901 is arranged on the inner side of the sealing ring 9, and a slot 902 is opened on the sealing ring 9. Reinforced steel rings 903 are arranged on both sides of the slot 902 of the sealing ring 9. The anti-slip pattern 901 increases the friction between the sealing ring 9 and the hardware pipe 8 to prevent the sealing ring 9 from sliding and deviating. The reinforced steel rings 903 on both sides of the sealing ring 9 can improve the pressure resistance of the sealing ring 9 and reduce the deformation degree of the sealing ring 9 under high temperature and high pressure environment.

[0024] An upper pressure plate 10 is installed on the sealing ring 9, and a lower pressure plate 11 is connected to the lower part of the upper pressure plate 10. First fixing plates 12 are connected to both sides of the upper pressure plate 10, and an elastic plate 13 is connected to the lower part of the first fixing plate 12. A clamping block 14 is connected to the lower part of the elastic plate 13. The clamping block 14 is triangular in design and is inserted into the through-hole groove 16. When the clamping block 14 passes through the through-hole groove 16, the second fixing holes 19 on the first fixing plate 12 and the second fixing plate 15 will be aligned with each other, so that it is convenient for the staff to screw the bolt assembly into the second fixing hole 19, and the upper pressure plate 10 and the lower pressure plate 11 are hooked together by the clamping block 14, which can prevent the upper pressure plate 10 or the lower pressure plate 11 from falling when the bolt is tightened, thereby improving the efficiency of installation and fixation.

[0025] The lower pressure plate 11 is connected to the second fixing plates 15 on both sides, the connecting block 6 is provided with a hexagonal groove, and the connecting block 6 is embedded in the fixing frame 1, and the first fixing plate 12 and the second fixing plate 15 are provided with a second fixing hole 19. The threaded rod 5 is rotated by the connecting block 6 to move the movable plate 7 downward, thereby clamping and fixing the hardware pipe 8, and the bolt assembly is screwed into the second fixing hole 19. The tightening force when the bolt is turned makes the upper pressure plate 10 and the lower pressure plate 11 press and fix the sealing ring 9 to prevent the sealing ring 9 from sliding.

[0026] A through hole groove 16 is provided on the second fixing plate 15, and an insert plate 17 is connected to the inner side of the upper pressing plate 10 and the lower pressing plate 11. The upper pressing plate 10 and the lower pressing plate 11 are connected to side plates 18 on both sides of the insert plate 17. The insert plate 17 is inserted into the slot 902. By inserting the insert plate 17 into the slot 902, the insert plate 17 can be tightened to support the sealing ring 9, thereby reducing the deformation of the sealing ring 9 through the support of the insert plate 17, and at the same time, the upper pressing plate 10 and the lower pressing plate 11 can cover the sealing ring 9 through the side plates 18, thereby protecting the sealing ring 9 and reducing the contact of the sealing ring 9 with the outside world.

[0027] The working principle of the utility model is:

[0028] By sleeve-fitting the sealing ring 9 at the connection of the two hardware pipes 8, and then inserting the insert plate 17 into the slot 902, the upper pressing plate 10 and the lower pressing plate 11 are brought into contact with each other. When in contact, the second fixing plate 15 pushes and squeezes the elastic plate 13 through the clamping block 14, so that the elastic plate 13 is deformed, and the clamping block 14 passes through the through-hole groove 16. The rebound of the elastic plate 13 enables the clamping block 14 to hook the second fixing plate 15, and the upper pressing plate 10 and the lower pressing plate 11 are hooked together, so that the second fixing holes 19 on the first fixing plate 12 and the second fixing plate 15 are aligned with each other, so that it is convenient for the staff to push the second fixing plate 15 to the second fixing plate 16. Bolts are screwed into holes 19 so that the upper pressure plate 10 and the lower pressure plate 11 press and fix the sealing ring 9, and the sealing ring 9 is supported by the plug plate 17 and the reinforcing steel ring 903, which can enhance the pressure resistance of the sealing ring 9 and reduce the deformation of the sealing ring 9. Then, the hardware pipe 8 is passed through between the movable plate 7 and the fixed frame 1. The staff presses the movable plate 7 and simultaneously turns the connecting block 6 to rotate the threaded rod 5, so that the movable plate 7 moves smoothly downward along the threaded rod 5, thereby clamping and fixing the hardware pipe 8, and then screws are screwed into the first fixing hole 2 to fix the fixed frame 1 and the hardware pipe 8 together on the wall or the ground.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
