The anti-skid patterns located on the second rectangular surface can provide connectivity between two adjacent rubber pads and reduce the sliding phenomenon between adjacent rubber pads.
[0021] The preferred technical solution of the utility model can also produce at least the following technical effects:
[0022] 1. By setting the rubber bottom layer into two symmetrical rubber strips, the dispersion surface between the rubber pad and the ground is increased, which is conducive to the micro-correction of uneven ground, thereby ensuring full contact between the rubber pad and the ground, and the rubber bottom layer separated into two rubber strips improves the deformation capacity of the rubber pad during pressure.

[0032] The following is combined with Figure 1-3 The present application is further described in detail. An embodiment of the present application discloses a rubber pad.
[0033] Example 1
[0034] Reference Figure 1 As shown, a rubber pad includes a rubber top layer 100 and a rubber bottom layer 200, wherein the rubber top layer 100 is provided with a rubber top surface 110 and a rubber bottom surface 120, and the rubber bottom layer 200 is provided on the rubber bottom surface 120 of the rubber top layer 100. The rubber bottom layer 200 and the rubber top layer 100 can be provided as one piece, or can be provided by injection molding separately and then bonded to each other.
[0035] In the embodiment of the present application, the rubber top layer 100 and the rubber bottom layer 200 are integrally arranged, which is convenient for production and processing and improves the connectivity between the rubber top layer 100 and the rubber bottom layer 200.
[0036] The rubber bottom layer 200 is two rubber strips 210 symmetrically arranged on the rubber bottom surface 120. The length extension direction of the two rubber strips 210 is extended along the length direction of the rubber top layer 100. The two symmetrically arranged rubber strips 210 are conducive to contact with the ground, thereby increasing the contact area between the rubber pad and the ground. In addition, the dispersion surface of the contact surface will be increased during the compression process of the rubber strips 210. In addition, the two rubber strips 210 arranged in blocks can make micro adjustments to the uneven ground.
[0037] In the embodiment of the present application, two rubber strips 210 are shown as an example, wherein the number of rubber strips 210 can be effectively adjusted as needed, thereby providing multiple settings.
[0038] The lengths of the two rubber strips 210 and the diameter of each rubber strip 210 can be adaptively adjusted according to different laying sites.
[0039] The end of the rubber strip 210 away from the rubber bottom surface 120 is provided with an arc surface 220, and the arc surface 220 completely wraps the end surface of the rubber strip 210 away from the rubber bottom surface 200, thereby increasing the deformation of the rubber. The arc surfaces 220 of the end surfaces of the two rubber strips 210 are connected to each other, and there is a gap between the arc surfaces 220 of the two rubber strips 210.
[0040] The arc surface 220 can be opened with arc surfaces 220 of different wrapping angles according to the required deformation of the rubber strip 210, and the deformation of the rubber pad can be adjusted by adjusting the size of the gap between the arc surfaces 220 of the two rubber strips 210.
[0041] The number of rubber strips 210 may also be set as needed according to the deformation amounts of different rubber pads.
[0042] The rubber top surface 110 is configured as a first rectangular surface 310 , and a plurality of anti-skid grooves 330 are formed on the first rectangular surface 310 . The plurality of anti-skid grooves 330 are evenly arranged along the length direction of the rubber top layer 100 , and the anti-skid grooves 330 are recessed toward the rubber top surface 110 .
[0043] The two side walls of the rubber top layer 100 in the length extension direction are respectively set as the second rectangular surface 320, the length direction of the second rectangular surface 320 is extended along the length of the rubber top layer 100, and the width direction of the second rectangular surface 320 is extended along the height of the rubber top layer 100. The height of the second rectangular surface 320 is adaptively changed according to the required thickness of the rubber pad.
[0044] The second rectangular surface 320 is also provided with a plurality of anti-skid patterns formed by inward depressions, and the plurality of anti-skid patterns are extended along the length direction of the rubber top layer 100. In addition, the anti-skid patterns in the embodiment of the present application are logo patterns provided on the rubber pad.
[0045] Each rubber strip 210 has a through hole 230 formed therein, and the length direction of the through hole 230 extends along the length direction of the rubber strip 210. The cross section of the through hole 230 may be a triangle, a rectangle, a pentagon, or the like.
[0046] In the embodiment of the present application, the cross-section of the through hole 230 is circular, that is, the inner wall of the through hole 230 is arranged in an arc shape, thereby improving the stability of the rubber strip 210, making it easy for the through hole 230 to recover during the compression deformation of the rubber strip 210, and not easy to produce horizontal and vertical displacement.
[0047] In the embodiment of the present application, the center line of the through hole 230 is arranged to coincide with the center line of the arc surface 220 , and two ends of the through hole 230 are penetrated by two ends of the rubber strip 210 in the width direction.
[0048] Example 2
[0049] The difference between the embodiment of the present application and the embodiment 1 is that the structural position of the through hole 230 is set differently.
[0050] In the embodiment of the present application, the rubber strip 210 is provided with a groove 240 , the notch of the groove 240 is arranged at the end surface of the rubber strip 210 facing away from the rubber bottom surface 120 , and the length direction of the groove 240 is extended along the length direction of the rubber strip 210 .
[0051] That is, the groove 240 is a through hole, so that the through hole 230 can be opened during the rubber pad manufacturing process, or it can be opened on the end surface of the rubber strip 210 after the rubber pad is manufactured, and is located at the notch opened on the rubber end surface, which facilitates the operation of the cutting knife during the opening of the through hole 230.
[0052] Example 3
[0053] The difference between the embodiment of the present application and the embodiment 1 is that the structural position of the through hole 230 is set differently.
[0054] In the embodiment of the present application, a plurality of through holes 230 are provided, and the plurality of through holes 230 are evenly arranged along the length direction of the rubber strip 210. The through holes 230 are opened inward from the end of the rubber strip 210 facing away from the rubber bottom surface 120, and the center line of the through hole 230 is perpendicular to the rubber bottom surface 120. During manufacturing, the through holes 230 are opened from the end surface of the rubber strip 210 facing inward, so as to facilitate the opening of the through holes 230, and the through holes 230 opened can be opened with different depths for different application scenarios, so as to change the deformation amount of the rubber strip 210 during use.
[0055] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
