Description

A type of plastic sealing gasket Technical Field

[0001] This utility model belongs to the field of sealing gasket technology, and in particular relates to a plastic sealing gasket. Background Technology

[0002] Plastics have a "cold flow property," which causes plastic gaskets to undergo plastic deformation under long-term continuous load, and gaskets are commonly used for sealing connections between pipes.

[0003] When traditional plastic gaskets are used, different parts are subjected to different forces. When the plastic gasket is subjected to force, because there is no buffering for these forces, the plastic gasket will deform, thereby affecting the sealing effect and service life of the plastic gasket. Summary of the Invention

[0004] The purpose of this invention is to provide a plastic sealing gasket to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: a plastic sealing gasket includes a support ring, with washers slidably connected to both the upper and lower sides of the support ring, and the edges of the upper and lower washers are connected by a plurality of damping columns arranged in a circumferential array, and the washers and the support ring are connected by a plurality of springs arranged in a circumferential array.

[0006] Preferably, the outer sidewall of the washer is provided with an outwardly protruding edge, the inner sidewall of the washer is provided with an inwardly protruding edge, and the inner wall of the outwardly protruding edge contacts the outer sidewall of the support ring, and the outer sidewall of the inwardly protruding edge contacts the inner sidewall of the support ring.

[0007] Preferably, a receiving groove is formed between the outer convex edge, the inner convex edge, and the washer, the support ring is located in the receiving groove, and the washer, the outer convex edge, and the inner convex edge are an integral structure.

[0008] Preferably, the inner wall of the support ring is provided with four limiting grooves arranged in a circumferential array, and the inner sidewall of the inner convex edge is provided with limiting blocks corresponding to the limiting grooves, and the limiting blocks are slidably connected to the limiting grooves.

[0009] Preferably, the damping column is made of rubber material and has a corrugated structure.

[0010] Preferably, the support ring has multiple grooves arranged in a circumferential array on both its upper and lower sides, and the spring is installed in the grooves.

[0011] The plastic sealing gasket of this utility model has the following advantages:

[0012] 1. This utility model, through the cooperation between the damping columns, provides good damping support between the upper and lower gaskets, effectively preventing the entire sealing gasket from becoming loose. Under the action of the middle support ring, when the two gaskets are squeezed together during installation, it provides good support for the two gaskets, effectively preventing the gaskets from deforming and affecting the sealing effect, thereby extending the service life of the sealing gasket.

[0013] 2. This utility model uses a spring in conjunction with a damping column to provide excellent cushioning for the gasket, thereby reducing the deformation of the sealing gasket and improving its service life. Attached Figure Description

[0026] As shown in Figures 1-4, a plastic sealing gasket of this utility model includes a support ring 1. Gaskets 2 are slidably connected to both the upper and lower sides of the support ring 1. The outer side wall of the gasket 2 is provided with an outward protruding edge 5, and the inner side wall of the gasket 2 is provided with an inward protruding edge 6. The inner wall of the outward protruding edge 5 contacts the outer side wall of the support ring 1, and the outer side wall of the inward protruding edge 6 contacts the inner side wall of the support ring 1. A receiving groove 8 is formed between the outward protruding edge 5, the inward protruding edge 6, and the gasket 2. The support ring 1 is located in the receiving groove 8, and the gasket 2, the outward protruding edge 5, and the inward protruding edge 6 are an integral structure. Through the cooperation between the outward protruding edge 5 and the inward protruding edge 6, the gasket 2 wraps around the support ring 1. The inner wall of the support ring 1 is provided with four limiting grooves 4 arranged in a circular array. The inner side wall of the inner convex edge 6 is provided with limiting blocks 7 corresponding to the limiting grooves 4. The limiting blocks 7 are slidably connected to the limiting grooves 4. Through the cooperation between the limiting blocks 7 and the limiting grooves 4, the washer 2 and the support ring 1 are effectively limited, so that the washer 2 and the support ring 1 can only move up and down, but cannot rotate relative to each other, thus ensuring the stability of the structure.

[0027] The edges of the upper and lower gaskets 2 are connected by multiple damping pillars 3 arranged in a circumferential array. The damping pillars 3 are made of rubber and have a corrugated structure. Through the cooperation of the damping pillars 3, a good damping support effect is achieved between the upper and lower gaskets 2, effectively preventing the entire gasket from becoming loose. Under the action of the middle support ring 1, when the two gaskets 2 are squeezed together during installation, a good support effect is achieved for the two gaskets 2, effectively preventing deformation of the gaskets and affecting the sealing effect, thereby extending the service life of the gasket. The gaskets 2 and the support ring 1 are connected by multiple springs 9 arranged in a circumferential array. Multiple grooves 10 arranged in a circumferential array are provided on both the upper and lower sides of the support ring 1. The springs 9 are installed in the grooves 10, and the grooves 10 limit the movement of the springs 9. The springs 9, in conjunction with the damping pillars 3, provide a good buffering effect for the gaskets 2, thereby reducing the degree of deformation of the gasket and improving its service life.
