[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0019] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts should fall within the scope of protection of the present invention.

[0020] Figure 1-3 It includes an end plate 1, a countersunk hole 1-1, a partition 2, a rubber 3, a ring groove 3-1, a rubber rod 4, etc.

[0021] like Figure 1-3 As shown, the utility model is an insulating rubber gasket, comprising two end plates 1 arranged parallel to each other, a countersunk hole 1-1 being provided at the rotation center of the end plate 1, a rubber component being arranged between the two end plates 1, a rubber rod 4 being provided through the rotation center of the rubber component, and the axial ends of the rubber rod 4 being guided and matched with the corresponding countersunk holes 1-1.

[0022] The rubber assembly includes a plurality of partitions 2 vulcanized and arranged in the rubber 3. The plurality of partitions 2 are parallel to each other and arranged at equal intervals.

[0023] The depth of the countersunk hole 1 - 1 is 3 mm, the diameter is 12 mm, and the outer diameter of the rubber rod 4 is 12 mm.

[0024] A plurality of annular grooves 3 - 1 are evenly distributed on the circumferential surface of the rubber 3 , and the annular grooves 3 - 1 are located between two adjacent partition plates 2 in the vertical direction.

[0025] The top corner of the annular groove 3-1 is constructed as an arc transition structure, the width of the annular groove 3-1 is 3.5 mm, and the bottom diameter of the annular groove 3-1 is 58 mm.

[0026] In specific production practice, the end plate 1 has a thickness of 6 mm and a diameter of 61.3 mm.

[0027] The outer diameter of the rubber 3 is 61.3 mm.

[0028] The distance between the top surface of the upper end plate and the bottom surface of the lower end plate is 45.5 mm.

[0029] The length of the rubber rod 4 is 39.5 mm. The thickness of the separator 2 is 1.5 mm.

[0030] The K value of the insulating rubber gasket of the utility model is calculated based on the displacement range of 0.16cm to 0.25cm, and the maximum load value is 9500kgf, which has exceeded the performance index of the existing shock absorber with similar appearance.

[0031] The utility model has a resistance of 550MΩ.

[0032] like Figure 1-3 As shown, the present invention uses an end plate 1, a partition 2, a rubber 3, and a rubber rod 4 that are vulcanized into one piece. During production, a countersunk hole with a depth of 3mm and an inner diameter of 12mm is machined in the center of the end plate 1. The partitions 2 are arranged in 6 layers, and a hole with a diameter of 12mm is machined in the center of each layer of partition 2. A hole with an inner diameter of 12mm is also machined in the center of the rubber 3. A rubber rod 4 with a diameter of 12mm is then vulcanized separately. The shape of the product is preformed before the product is officially vulcanized. The preformed semi-finished product is then added to a rubber vulcanization mold for vulcanization into one piece. This effectively ensures that each layer of partition 2 is covered by the rubber 3, and that the thickness of each layer of partition 2 and rubber 3 is uniform, allowing the rubber seal to withstand high impact loads without deformation and ensuring the vertical static load spring rate of the product.
