[0017] like Figure 1 , Figure 2 As shown, a split vibration isolator gasket is arranged in the vibration isolator. The vibration isolator includes an outer tube, an inner tube, and a compression element. The gasket includes an outer pad 1 fixedly connected to the inner wall of the outer tube, an inner pad 2 connected to the inner tube, and a guiding mechanism for guiding the up and down movement direction of the inner tube. A plurality of top plates 3 extending outward are provided on the inner pad 2. The number of the top plates 3 is 2-4 and can be arranged as needed. A through hole 4 with the same shape as the inner pad 2 and through which the inner pad can pass is provided on the outer pad 1.

[0018] like Figure 1 , Figure 3 As shown, the guiding mechanism includes a plurality of first threaded holes 5 provided on the outer pad 1, the number of the first threaded holes 5 is 4-8, in order to facilitate the installation of the guiding rod 6 and the inner cylinder, the diameters of two adjacent first threaded holes 5 may be different, and a guiding rod 6 is provided through the first threaded holes 5 to penetrate into the inner cylinder and guide the inner cylinder to move up and down, the guiding rod 6 includes a threaded section 7 in contact with the first threaded hole 5, and a smooth section 8, the length of the threaded section 7 may be slightly longer than the length of the first threaded hole 5, so as to ensure that the guiding rod 6 is fixed.

[0019] A plurality of grooves 9 for placing compression elements are provided on the inner pad 2, and a central hole 10 for the compression element to pass through can also be provided in the center of the inner pad 2. One or more compression elements can be provided according to the requirements of the vibration isolation frequency.

[0020] The inner pad 2 is provided with a plurality of second threaded holes 11 for fixing the inner pad 2 to the inner tube.

[0021] The thickness of the outer pad 1 and the inner pad 2 is 10-50 mm, and the appropriate thickness can be set according to needs.

[0022] When in use, the outer pad 1 and the outer cylinder can be fixedly connected by welding, and the inner pad 2 is threadedly connected to the inner cylinder. The inner pad 2 is rotated to make the top plate 3 on the inner pad 2 contact and squeeze with the lower surface of the outer pad 1. When the equipment vibrates, the vibration is transmitted to the inner pad 2 and the inner cylinder through the outer cylinder and the compression element, and then the vibration is transmitted to the earth, which greatly protects the equipment. The guide rod 6 guides the inner cylinder to move up and down to prevent the inner cylinder from rubbing against the outer cylinder and the friction between the side wall of the gasket and the inner wall of the outer cylinder. The outer pad 1 is in contact and squeezed with the inner pad 2 without friction, and the extrusion deformation is small, which greatly improves the service life. When the vibration is large, the outer pad 1 plays the role of limiting the inner pad 2 to prevent the equipment from being damaged by rebound shock. When disassembling, the inner cylinder can be rotated and the inner pad 2 can be removed through the through hole 4. The disassembly is convenient. The overall structure of the present application is simple, the cost is low, and the operation is convenient.

[0023] The above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
