[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. In addition, for the convenience of description below, the "upper", "lower", "left", "right", etc. cited are consistent with the upper, lower, left, right, etc. of the accompanying drawings themselves. The "first", "second", etc. in the following text are for descriptive distinction and have no other special meanings.

[0033] In view of the problems existing in the prior art, the present invention provides a composite rubber pad structure under the rail. The rubber pad includes a fiber rubber outer layer, a fiber rubber connection layer provided at the outer end of the fiber rubber outer layer, and an anti-slip bottom pad installed on the lower surface of the fiber rubber outer layer, which is specifically described as follows:

[0034] 2 - Groove

[0035] Groove, the upper surface of the above-mentioned fiber rubber outer layer is equally spaced with grooves, and the lower inner surface of the fiber rubber outer layer is provided with a first anti-slip and wear-resistant layer, and a first reinforcement layer is installed at the lower end of the first anti-slip and wear-resistant layer. The setting of the groove will increase the roughness of the surface of the fiber rubber outer layer, and can play an anti-slip role when placed under the composite rail.

[0036] In some examples, the above-mentioned fiber rubber connection layer further includes a positioning groove opened inside the fiber rubber connection layer, and a protrusion is provided inside the positioning groove. Through the setting of the fiber rubber connection layer, the rubber pad will be connected through the fiber rubber outer layer and the fiber rubber connection layer, making the surface not a uniform smooth connection, thereby increasing friction.

[0037] In some examples, the above-mentioned protrusions are equally spaced on the surface of the fiber rubber connection layer, and the longitudinal section of the protrusion is a circular structure to play a role in increasing friction. Through the setting of the protrusions, the roughness of the surface of the fiber rubber connection layer will be increased, so that the surfaces of the fiber rubber outer layer and the fiber rubber connection layer are not smooth structures, so as to achieve a better anti-slip effect after placement.

[0038] In some examples, the above-mentioned first reinforcement layer further includes a first rubber soft block disposed at the lower end of the first reinforcement layer, and a second reinforcement layer is installed at the lower end of the first rubber soft block. Second rubber soft blocks are equidistantly arranged at the upper end of the second reinforcement layer. The arrangement of the first rubber soft block and the second rubber soft block will increase the internal tightness, making the interior more firm when rolling on the surface of the fiber rubber outer layer.

[0039] In some examples, the above-mentioned first rubber soft blocks are equidistantly arranged on the lower surface of the first reinforcement layer, and the first rubber soft blocks and the second rubber soft blocks are arranged alternately left and right. Through the alternating arrangement of the first rubber soft block and the second rubber soft block, the connection between the first reinforcement layer and the second reinforcement layer is tightened, increasing the internal firmness.

[0040] 12 - Spacer layer

[0041] Spacer layer, a spacer layer is provided on the lower side of the first reinforcement layer, and a second anti-slip and wear-resistant layer is installed at the lower end of the spacer layer. The arrangement of the spacer layer creates a connection gap inside the fiber rubber outer layer, which can save connection materials.

[0042] In some examples, the above-mentioned spacer layer further includes a rubber circular pad disposed at the outer end of the spacer layer, and a second rubber soft cylinder installed at the lower end of the second reinforcement layer is provided inside the rubber circular pad. A buffer spring is installed inside the second rubber soft cylinder, and a first tensile soft cylinder is provided at the outer end of the buffer spring. Through the arrangement of the rubber circular pad, the roughness of the spacer layer surface is increased, the connection gap is increased, and the rubber pad is made lighter.

[0043] In some examples, the above-mentioned rubber circular pads are evenly arranged at the outer end of the spacer layer, and the rubber circular pads and the second rubber soft cylinders are symmetrically arranged left and right. Through the arrangement of the second rubber soft cylinder, the buffer spring is installed inside it to prevent the buffer spring from shifting.

[0044] In some examples, the above-mentioned first tensile soft cylinder is relatively movably connected to the second rubber soft cylinder through the buffer spring to play a role in rolling buffering. The buffer spring is placed inside the first tensile soft cylinder. When the surface of the fiber rubber outer layer is squeezed, the internal buffer spring is compressed, and the first tensile soft cylinder slides inside the second rubber soft cylinder, thereby buffering the interior.
