[0024] This embodiment is a pressure equalizing ring assembly.

[0025] like Figure 1-4As shown, it includes an upper ring body 1, a lower ring body 2 and a connecting frame 3. The number of the connecting frames 3 is two groups. The two groups of connecting frames 3 are fixedly installed between the left and right sides of the upper end outer surface of the lower ring body 2 and the left and right sides of the lower end outer surface of the upper ring body 1. The left and right sides of the inner wall of the upper ring body 1 are fixedly installed with a first connecting arm plate 6. A mounting plate 4 is provided at the center position of the upper ring body 1. An anti-loosening structure 5 is fixedly installed on the upper end outer surface of the mounting plate 4. Second connecting arm plates 7 are fixedly installed on the outer surfaces of both sides of the mounting plate 4. The anti-loosening structure 5 includes a mounting shell 8, a limiting ring 9, an extrusion rod 10, a limiting block 11 and a compression spring 12, and the mounting shell 8 is fixedly installed in the middle of the upper end outer surface of the mounting plate 4.

[0026] There are two groups of limit rings 9 and extrusion rods 10, and the two groups of limit rings 9 are fixedly installed on the left and right sides of the middle part of the outer surface of the lower end of the mounting plate 4; the extrusion rod 10 passes through the limit ring 9, and the limit block 11 and the compression spring 12 are both located inside the mounting shell 8, and the two groups of extrusion rods 10 are fixedly installed on the left and right sides of the lower outer surface of the limit block 11; the compression spring 12 is fixedly installed between the upper outer surface of the limit block 11 and the upper part of the inner cavity of the mounting shell 8; the outer wall of the extrusion rod 10 is slidably connected to the limit ring 9; the upper outer surface of the limit block 11 is elastically connected to the upper part of the inner cavity of the mounting shell 8 through the compression spring 12, and the outer wall of the limit block 11 is slidably connected to the inner wall of the mounting shell 8.

[0027] It should be noted that the utility model is a pressure-equalizing ring assembly.

The connecting frame 3 is connected between the upper ring body 1 and the lower ring body 2, which can be effectively known to the technicians in the relevant technical field, and the details are not repeated here. The installation disk 4 is set. After the installation disk 4 is installed by fixing bolts, the extrusion rod 10 in the anti-loosening structure 5 is squeezed, and the lower end of the extrusion rod 10 enters the limit ring 9. The extrusion rod 10 drives the limit block 11 to squeeze the compression spring 12 inside the installation shell 8.

The first connecting arm plate 6 and the second connecting arm plate 7 are detachably connected, which is convenient for replacing the installation disk 4 after disassembling it. After replacing the installation disks 4 of different diameters, the applicability can be improved.
