Description

Technical Field

[0001] The invention relates to the technical field of assembly gaskets, in particular to a shock-absorbing guide seat gasket with a wedge-shaped inner hole. Background Art

[0002] A gasket is a mechanical seal between two objects, usually used to prevent leakage between the two objects due to pressure, corrosion and natural thermal expansion and contraction of the pipeline. Since it is impossible for the machined surface to be perfect, irregularities can be filled with gaskets. Gaskets are usually made of paper, rubber or copper sheets, and are placed between two planes to strengthen the sealing material. They are sealing elements set between static sealing surfaces to prevent fluid leakage. The parts used with gaskets usually include shock-absorbing guide seats, springs and nuts.

[0003] However, due to long-term running-in and use, the existing shock-absorbing guide seat gasket is easily damaged and loses its elasticity, and needs to be replaced as a whole. In addition, dust can easily enter the shock-absorbing guide seat, causing a large amount of dust to adhere to the inside, affecting the shock-absorbing effect. For this reason, we propose a shock-absorbing guide seat gasket with a wedge-shaped inner hole. Summary of the invention

An evenly distributed upper anti-slip tooth plate 2 is fixedly installed at the bottom of the fixed base plate 1, and a limiting rubber plate 3 is fixedly sleeved in the middle of the top of the fixed base plate 1. A circular through hole is opened in the middle of the top of the limiting rubber plate 3, and the circular through hole on the limiting rubber plate 3 sequentially penetrates the limiting rubber plate 3, the fixed base plate 1, the middle sandwich plate 6, the compacting base plate 7 and the protective plate 9, which is convenient for installation. The rod is inserted to fix the shock-absorbing guide seat, making the structure more stable. A fixed sleeve on one side of the top of the fixed base plate 1 is provided with a positioning block 4 located on one side of the limiting rubber plate 3. A threaded groove is provided inside the positioning block 4, and the threaded groove on the positioning block 4 extends to the inside of the middle sandwich plate 6.

The sliding connection is convenient for blocking dust on the outside of the fixed base plate 1, preventing external dust from entering the shock-absorbing guide seat for a long time, thereby affecting the shock-absorbing effect of the shock-absorbing device. An intermediate sandwich plate 6 is arranged below the fixed base plate 1. The material of the intermediate sandwich plate 6 is rubber, and the top and bottom of the intermediate sandwich plate 6 are distributed with teeth that are engaged with the upper anti-skid tooth plate 2 and the lower anti-skid tooth plate 10, so that the gasket has better elasticity, ensures the ductility of the gasket, and is easy to replace. A compacting base plate 7 is arranged below the intermediate sandwich plate 6, and the external fixed The set is equipped with an anti-backflow plate 8, which is circular in shape, and the outer surface of the anti-backflow plate 8 is slidably connected to the side wall of the wedge-shaped inner hole, which is convenient for secondary protection against dust and improves the practicability of the device. The bottom of the compaction base plate 7 is fixedly connected with a protective plate 9, and the top of the compaction base plate 7 is fixedly installed with a lower anti-slip tooth plate 10 located below the middle sandwich plate 6, which is convenient for replacing the damaged middle sandwich plate 6 in the device, avoiding the problem of large wear and tear of the gasket due to long-term use, loss of elasticity, and the need to replace the entire gasket, thereby reducing costs and improving the practicability of the device.

[0023] During operation, first place the gasket on the wedge-shaped inner hole, and at the same time, pass the mounting rod through the gasket and fix it with a bolt through the positioning block 4. When the middle sandwich plate 6 is damaged, unscrew the bolt and pull the limiting rubber plate 3 outward to release the clamping connection between the upper anti-slip tooth plate 2 and the middle sandwich plate 6, and then take out the middle sandwich plate 6 for replacement.
