Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] Specific embodiments are given below.

[0020] Please refer to Figure 1 、 Figure 2The utility model provides a kind of corrosion-resistant damping block, including damping block body 1;The end of the damping block body 1 is circumferentially arrayed and provided with buffer groove 11;Spring assembly 12 is equipped in the buffer groove 11;The spring assembly 12 is fixedly connected with damping block body 1;Polytetrafluoroethylene layer 13 is equipped in the top of the damping block body 1;The spring assembly 12 is fixedly connected with polytetrafluoroethylene layer 13;When working, the pressure received by the top of damping block body 1 acts on polytetrafluoroethylene layer 13 after being placed in determined position, the spring assembly 12 of the lower part of polytetrafluoroethylene layer 13 is also compressed under pressure, while spring assembly 12 generates counterforce to polytetrafluoroethylene layer 13, bidirectional extrusion force can be generated to polytetrafluoroethylene layer 13 at this time, and then the expansion effect of polytetrafluoroethylene layer 13 is improved, the expansion area of polytetrafluoroethylene layer 13 is increased, so that the gap area of extrusion filled by it can be increased, so that the corrosion resistance of polytetrafluoroethylene layer 13 itself and expansion area can be reduced to reduce the intrusion of chemical medium to damping block body 1, and the corrosion resistance of damping block body 1 is improved.The design is provided with polytetrafluoroethylene layer on the top of damping block, and the corrosion resistance of damping block body 1 is protected by polytetrafluoroethylene layer, and the expansion filling area of polytetrafluoroethylene layer is improved by the reverse automatic extrusion effect of polytetrafluoroethylene layer 13, so that the comprehensive protection of damping block is improved, and the corrosion caused by the reaction of damping block and chemical medium is reduced.

[0021] Further, as shown in Figure 2 The end of the damping block body 1 is fixedly connected with sealing ring 2;When working, water is isolated by sealing ring 2 and expanded polytetrafluoroethylene layer 13, and the penetration of water into damping block body 1 is reduced, and the bottom of polytetrafluoroethylene layer 13 is limited by sealing ring 2 when polytetrafluoroethylene layer 13 is extruded and expanded, so that the expansion direction of polytetrafluoroethylene layer 13 is concentrated to the outside, so that the expansion degree of polytetrafluoroethylene layer 13 is improved, and the isolation effect of polytetrafluoroethylene layer 13 is improved.The design is provided with a sealing ring on the top of damping block, the inflow of water is reduced, and the expansion direction of polytetrafluoroethylene layer is limited, so that the expansion effect of polytetrafluoroethylene layer 13 is improved, and the effective area of polytetrafluoroethylene layer 13 is improved.

[0022] Further, as shown in Figure 2As shown, the damping block body 1 is fixed with a fluororubber layer 3 on the surface; during operation, the fluororubber layer 3 can cooperate with the movement of the damping block body 1 to provide certain buffering effect at the four corners, thereby improving the working stability of the damping block body 1. Meanwhile, the fluororubber layer 3 has excellent corrosion resistance. The fluororubber layer arranged at the four corners of the damping block body 1 can cooperate with the movement of the damping block, thereby improving the movement stability of the damping block and reducing the penetration of chemical media into the four corners of the damping block, which can accelerate the corrosion of the damping block.

[0023] Further, as shown in Figure 2 As shown, the damping block body 1 is fixed with a water-repellent layer 4 on the surface; during operation, the water-repellent layer 4 can play a waterproof role to reduce the entry of large amounts of humid air and moisture into the damping block body 1. This design reduces the penetration of moisture into the damping block by waterproofing the surface of the damping block body 1, thereby slowing down the corrosion caused by the accumulation of moisture inside the damping block.

[0024] Working principle: when the damping block body 1 is placed in a certain position, the pressure on the top acts on the polytetrafluoroethylene layer 13, and at the same time, the spring assembly 12 at the lower part of the polytetrafluoroethylene layer 13 is also compressed under pressure, and the spring assembly 12 generates a counterforce to the polytetrafluoroethylene layer 13. At this time, the polytetrafluoroethylene layer 13 can generate bidirectional extrusion force, thereby improving the expansion effect of the polytetrafluoroethylene layer 13 and increasing the expansion area of the polytetrafluoroethylene layer 13, so that the expansion area of the extrusion part can be increased, thereby reducing the intrusion of chemical media into the damping block body 1 and improving the corrosion resistance of the damping block body 1. This design provides the damping block with a polytetrafluoroethylene layer on the top, which can protect the damping block body 1 from corrosion. Meanwhile, the polytetrafluoroethylene layer 13 can automatically extrude in the opposite direction, thereby increasing the expansion and filling area of the polytetrafluoroethylene layer, and further improving the overall protection of the damping block and reducing the corrosion caused by the reaction of the damping block with chemical media. During operation, the sealing ring 2 cooperates with the expanded polytetrafluoroethylene layer 13,

[0025] The sealing ring 2 can limit the bottom of the polytetrafluoroethylene layer 13 when the polytetrafluoroethylene layer 13 is extruded and expanded, so that the expansion direction of the polytetrafluoroethylene layer 13 is concentrated to the outside, thereby improving the expansion degree of the polytetrafluoroethylene layer 13, and further improving the isolation effect of the polytetrafluoroethylene layer 13. The design sets a sealing ring on the top of the damping block to reduce the inflow of moisture, and can limit the polytetrafluoroethylene layer to expand outward, thereby improving the expansion effect of the polytetrafluoroethylene layer 13, and further improving the effective area of the polytetrafluoroethylene layer 13. During work, the fluororubber layer 3 can cooperate with the movement of the damping block body 1 to provide certain buffering effect at the four corners, thereby improving the working stability of the damping block body 1. The fluororubber layer 3 has excellent corrosion resistance. The fluororubber layer set at the four corners of the damping block body 1 can cooperate with the movement of the damping block to improve the movement stability of the damping block, and reduce the chemical medium penetration at the four corners of the damping block, thereby reducing the corrosion of the damping block. During work, the hydrophobic layer 4 can play a waterproof role to reduce the entry of large amounts of humid air and moisture into the damping block body 1. The design waterproofs the surface of the damping block body 1 to reduce the penetration of moisture into the damping block, thereby slowing down the corrosion caused by the accumulation of moisture in the damping block.
