Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical accessories, in particular to an anti-falling sealing ring. Background Art

[0002] Sealing rings should have good sealing performance within a certain range of working pressure and temperature, and automatically improve their sealing performance as pressure increases. They should also be highly corrosion-resistant, not prone to aging, have a long service life, and be wear-resistant. Sealing rings are required to connect two workpieces. Most existing sealing rings are directly glued between the two workpieces, which can easily shift and fall off during use, resulting in poor sealing and leakage. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an anti-falling sealing ring, which effectively solves the problem of poor sealing.

[0004] The technical solution to solve the technical problem is: it includes a fixing pad, a plurality of countersunk holes are evenly arranged on the circumference of the fixing pad, a raised circular ring block is fixed on the fixing pad, a sealing pad is provided above the fixing pad, a circular ring groove corresponding to the upper and lower parts of the circular ring block is provided on the bottom surface of the sealing pad, a plurality of limit grooves are evenly arranged radially on the fixing pad, a limit block corresponding to the limit groove is fixed on the circumference of the sealing pad, the limit block is located below the sealing pad, the sealing pad and the limit block are fixedly connected via a connecting block, the sealing pad and the fixing pad fit together up and down, the circular ring block is inserted into the circular groove, and the limit block is inserted into the limit groove.

[0005] Preferably, the number of the countersunk holes is four, and screws are installed in the countersunk holes.

[0006] Preferably, the fixing pad and the annular block are made of an integrally formed rubber material, and the sealing pad, the connecting block and the limiting block are also made of rubber material.

[0007] Preferably, the connecting block is located outside the sealing gasket.

[0008] The utility model has the following advantages over traditional equipment: the structure is ingenious, the fixing pad is first fixed to the workpiece by screws to prevent the fixing pad from moving, and then the sealing pad is fitted on the fixing pad to completely cover the screws, thereby ensuring the overall sealing effect of the sealing pad and the fixing pad, the circular ring block fits with the annular groove, and the limit block is inserted into the limit groove to prevent the sealing pad from moving, with good sealing performance, anti-falling, simple operation, and convenient and practical.

[0014] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 A sealing ring to prevent falling off is provided, comprising a fixed pad 1, a plurality of countersunk holes 2 are evenly arranged on the circumference of the fixed pad 1, a raised circular ring block 3 is fixed on the fixed pad 1, a sealing pad 4 is provided above the fixed pad 1, and a circular ring groove 5 corresponding to the upper and lower sides of the circular ring block 3 is provided on the bottom surface of the sealing pad 4, a plurality of limiting grooves 6 are evenly arranged radially on the fixed pad 1, a limiting block 7 corresponding to the limiting groove 6 is fixed on the circumference of the sealing pad 4, the limiting block 7 is located below the sealing pad 4, the sealing pad 4 and the limiting block 7 are fixedly connected via a connecting block 8, the sealing pad 4 fits together with the fixed pad 1 up and down, the circular ring block 3 is inserted into the circular groove 5, and the limiting block 7 is inserted into the limiting groove 6.

[0016] There are four countersunk holes 2 , and screws 9 are installed in the countersunk holes 2 .

[0017] The fixing pad 1 and the annular block 3 are made of an integrally formed rubber material, and the sealing pad 4, the connecting block 8 and the limiting block 7 are also made of rubber material.

[0018] The connecting block 8 is located outside the sealing gasket 4 .

[0019] When the present invention is in use, the lower surface of the fixing pad 1 is complete and smooth. First, place the lower surface of the fixing pad 1 on the workpiece to be installed, place the screw 9 in the countersunk hole 2, pass the screw 9 through the fixing pad 1 and fix the fixing pad 1 on the workpiece to ensure the sealing effect of the lower surface of the fixing pad 1 and the surface of the workpiece. The head of the screw 9 is located inside the countersunk hole 2 to ensure the smoothness of the upper surface of the fixing pad 1. Then place the sealing pad 4 on the fixing pad 1, and the connecting block 8 is located on the outside of the sealing pad 4. The connecting block 8 does not interfere with the upper and lower fitting of the sealing pad 4 and the fixing pad 1. The number of the limit blocks 7 is four. When When the limiting block 7 is clamped in the limiting groove 6, the connecting block 8 is in a tensioned state, ensuring the overall clamping effect of the sealing gasket 4 and the fixed gasket 1, and effectively preventing the sealing gasket 4 from moving in the fixed gasket 1. At the same time, the annular block 3 is clamped in the annular groove 5 up and down, further ensuring the sealing of the sealing gasket 4 and the fixed gasket 1 up and down. The sealing gasket 4 and the fixed gasket 1 are fixed together with high stability and will not move or fall off. The upper surface of the sealing gasket 4 is smooth, and the upper surface of the sealing gasket 4 can be fitted with another workpiece. By locking the two workpieces, the sealing effect between the two workpieces is guaranteed, and the stability is good.

[0020] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
