[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 An antistatic flame-retardant rubber sheet includes a middle plate 10, a bottom plate 20, and a top plate 30. The bottom plate 20 and the top plate 30 are respectively bonded to the bottom and top of the middle plate 10, so that the middle plate 10, the bottom plate 20, and the top plate 30 form a three-plate plate structure.

[0023] See Figure 2 The middle plate 10 includes an even number of flame retardant rubber plates 11 and a plurality of filling columns 13. The even number of flame retardant rubber plates 11 are spliced ​​together to form a rectangular shape, and the contact surfaces are bonded and fixed with adhesive. Reinforcement flanges 12 are formed on the top and bottom of the inner edge of the flame retardant rubber plate 11 to enhance its mechanical strength. The reinforcement flange 12 includes a plurality of straight edge segments 121 and a plurality of arc edge segments 122. The two ends of each arc edge segment 122 are fixedly connected to a straight edge segment 121, so that a cavity is formed between adjacent reinforcement flanges 12 using symmetrical arc edge segments 122. A plurality of filling columns 13 are respectively inserted into the gaps between adjacent reinforcement flanges 12, and the inner diameter of the arc edge segment 122 is adapted to the diameter of the filling column 13.

[0024] In this embodiment, the bottom plate 20 and the top plate 30 are configured to be symmetrical to each other, and conductive agents are added to both the top plate 30 and the bottom plate 20. The conductive agents can be conductive materials such as metal powder, carbon black, etc. that are already available in the prior art.

[0025] See Figure 3 The top plate 30 includes a number of interlocking plates 31 and a cover plate 32, equal in number to the number of flame-retardant rubber plates 11. The interlocking plates 31 are formed on the side of the cover plate 32 facing the middle plate 10. The thickness of the raised straight edge segments 121 and curved edge segments 122 is equal to the thickness of the interlocking plates 31. Positioning grooves 33 are formed between the interlocking plates 31 to mate with the reinforcement flanges 12, ensuring that the top plate 30 is positioned properly during placement and that the interlocking plates 31 are flush with the reinforcement flanges 12.

[0026] By adding a conductive agent to both the top plate 30 and the bottom plate 20, and the upper and lower ends of the filling columns 13 made of conductive metal material being in contact with the top plate 30 and the bottom plate 20 respectively, the rubber sheet has excellent anti-static properties, which can effectively prevent the accumulation and discharge of static electricity, and can transfer static electricity from the surface of the rubber sheet to the bottom plate and release it to the grounding device in the factory area, ensuring the safety of the rubber sheet during use.

[0027] See Figure 1The number of flame-retardant rubber plates 11 is set to four, and the filling columns 13 distributed between the four flame-retardant rubber plates 11 are arranged in a cross shape in the middle of the middle plate 10. The multiple filling columns 13 can help enhance the overall mechanical strength of the middle plate 10. In addition, the number of flame-retardant rubber plates 11 can be adjusted according to processing needs. For example, the number of flame-retardant rubber plates 11 can be set to two, and the filling columns 13 distributed between the two flame-retardant rubber plates 11 are arranged in a straight line in the middle of the middle plate 10. Through the coordinated arrangement of the middle plate 10, the bottom plate 20 and the top plate 30, the rubber plate can be used to transfer static electricity from the surface plate to the bottom plate to ensure the safe discharge of static electricity. A reinforcing structure can also be added to the inside of the rubber plate to improve the mechanical properties of the rubber plate and reduce its compression deformation damage.

[0028] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
