A permeable running track made of EPDM rubber material

Abstract

A permeable running track made of EPDM rubber material, belonging to the field of running tracks, addresses the problem of existing splicing boxes using threaded rods for connection. This requires numerous rotations of the threaded rod to complete installation and disassembly, leading to cumbersome processes and reduced efficiency. By incorporating a limit mechanism and a pushing mechanism, installation is completed with a half-turn rotation of the limit mechanism, and disassembly requires only a half-turn rotation to release the limit mechanism and allow the pushing mechanism to push it out. Compared to existing technologies, this significantly improves the efficiency of rubber replacement by eliminating the need for numerous rotations of the threaded rod.

Description

Technical Field

[0001] This invention relates to the field of running tracks, and in particular to a permeable running track made of EPDM rubber material. Background Technology

[0002] A permeable running track is a type of track laid in playgrounds, sports fields, and other venues for people to run. For example, the patent with publication number CN216615368U uses several rectangular boxes on a leveling layer as the space for installing the unit-type rubber running track surface layer. The installation is done by pouring, which facilitates the replacement and renovation of the rubber running track later. It also facilitates later maintenance and repair, and avoids the problems of uneven repairs or large repair workload after a large-area replacement process.

[0003] Patent CN216615368U discloses a replaceable rubber running track, comprising an asphalt base layer, a primer layer, a granular layer, and a leveling layer. The primer layer is installed on the asphalt base layer, the granular layer is laid on the primer layer, and the leveling layer is laid on the granular layer. The leveling layer is provided with a detachable splicing surface layer. To facilitate subsequent maintenance, existing rubber running tracks are designed as multiple splicing boxes, which can be removed for maintenance. However, existing splicing boxes are connected using threaded rods, requiring many turns of the threaded rod to complete the installation and disassembly, making installation and disassembly very troublesome and affecting the efficiency of installation and disassembly.

[0004] To address the aforementioned problems, a permeable running track made of EPDM rubber material is proposed. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-9 The present invention provides a technical solution: a permeable running track made of EPDM rubber material, comprising an asphalt layer 1, a base layer 2 disposed above the asphalt layer 1, a granular layer 3 disposed above the base layer 2, a leveling layer 4 disposed above the granular layer 3, a first splicing box 5 disposed above the leveling layer 4, EPDM rubber 6 disposed inside the first splicing box 5, a second splicing box 9 disposed to the right of the first splicing box 5, a first vent 12 disposed inside the EPDM rubber 6, a second vent 13 disposed inside the lower part of the first splicing box 5, a limiting mechanism 7 disposed inside the second splicing box 9, and a pushing mechanism 8 disposed inside the limiting mechanism 7;

[0031] The first splicing box 5 has a first groove 10 inside. The limiting mechanism 7 includes a first connecting rod 701 disposed inside the first groove 10. The first connecting rod 701 has a second groove 702 inside. The second groove 702 has a support rod 712 inside. The support rod 712 has a fourth groove 713 inside. The lower inner side of the fourth groove 713 has a first fixing rod 703. The upper end of the first fixing rod 703 is fixedly connected to a second connecting rod 704. The upper end of the second connecting rod 704 is fixedly connected to a fixing plate 716. The upper part of the fixing plate 716... The square has a fifth groove 705 inside. A rotating disk 715 is fixedly connected to the outside of the second connecting rod 704. A torsion spring 706 is provided below the rotating disk 715. A fixing ring 707 is fixedly connected to the bottom of the torsion spring 706. A first limiting groove 708 is provided inside the outside of the first fixing rod 703. A limiting rod 709 is provided inside the first limiting groove 708. A first hole 710 is connected to the outside of the inner wall of the fourth groove 713. A second limiting groove 711 is connected to the outside of the inner side of the first groove 10. A second hole 714 is connected to the outside of the inner wall of the second groove 702.

[0032] The first groove 10 and the first connecting rod 701 are in clearance fit, and the first connecting rod 701 has a "T" shape in its top view structure, so that the first connecting rod 701 can be placed inside the first groove 10, so that there will be no lateral movement between the first splicing box 5 and the second splicing box 9.

[0033] The first fixing rod 703 has a cylindrical shape, and its outer surface fits against the inner surface of the fourth groove 713, allowing the first fixing rod 703 to rotate inside the fourth groove 713 without wobbling.

[0034] The central axis of the first fixed rod 703 coincides with the central axis of the second connecting rod 704, and the central axis of the second connecting rod 704 coincides with the central axis of the fixed plate 716. The connection between the fixed plate 716 and the first connecting rod 701 is a rotatable connection, so that rotating the fixed plate 716 can drive the first fixed rod 703 to rotate, and the fixed plate 716 will not move up and down to detach from the support rod 712.

[0035] The width of the inner hole of the fixed ring 707 is greater than the width of the second connecting rod 704, and the connection between the fixed ring 707 and the support rod 712 is a fixed connection, so that the torsion spring 706 will not drive the fixed ring 707 to rotate when it rotates.

[0036] The top view of the first limiting groove 708 is arc-shaped, and the inner wall of the first limiting groove 708 fits against the inner wall of the limiting rod 709. The limiting rod 709 is connected to the first fixed rod 703 by a sliding connection, so that when the first fixed rod 703 rotates, it can drive the limiting rod 709 to slide along the inclined side of the first limiting groove 708 toward the middle of the first fixed rod 703.

[0037] The width of the limiting rod 709 is the same as the width of the first hole 710, and the width of the limiting rod 709 is the same as the width of the second limiting groove 711, so that the limiting rod 709 can pass into the interior of the second limiting groove 711 and the first hole 710 when it moves.

[0038] The first fixing rod 703 has a third groove 11 in the middle. The pushing mechanism 8 includes a first push rod 801 disposed inside the third groove 11. The outer side of the third groove 11 is connected to a guide groove 802. The inner side of the guide groove 802 is provided with a guide rod 803. The lower end of the first push rod 801 is provided with a second push rod 804. The lower part of the fourth groove 713 is connected to a third hole 805.

[0039] The guide groove 802 has a spiral shape, and the width of the guide groove 802 is the same as the width of the guide rod 803. The guide rod 803 is fixedly connected to the first push rod 801, so that the guide rod 803 can move inside the guide groove 802 without shaking. When the guide rod 803 rotates along the trajectory of the guide groove 802, it will move downward and thus drive the first push rod 801 to move downward.

[0040] The second push rod 804 has a cuboid shape and is clearance-fitted with the third hole 805. Furthermore, the second push rod 804 is fixedly connected to the first push rod 801. This ensures that when the first push rod 801 moves downwards, the second push rod 804 will not rotate and will only move downwards within the third hole 805 without wobbling.

[0041] When the splicing box needs to be replaced, use a flathead screwdriver to align with the fifth groove 705, and rotate the flathead screwdriver to rotate the fixing plate 716. Because the fixing plate 716 is fixedly connected to the first fixing rod 703 and the second connecting rod 704, rotating the fixing plate 716 will cause the first fixing rod 703 to rotate. The first fixing rod 703 has a cylindrical shape, and its outer surface is in contact with the inner surface of the fourth groove 713. The first limiting groove 708 has an arc shape when viewed from above, and its inner wall is in contact with the inner wall of the limiting rod 709. The connection between the limiting rod 709 and the first fixed rod 703 is a sliding connection, allowing the limiting rod 709 to move along the circular inclined side of the first limiting groove 708 towards the central axis of the first fixed rod 703. Since the width of the limiting rod 709 is the same as the width of the first hole 710 and the width of the limiting rod 709 is the same as the width of the second limiting groove 711, the limiting rod 709 moves from the inside of the second limiting groove 711 to the inside of the first hole 710. When the first fixed rod 703 rotates, because the guide groove 802 has a spiral shape and its width is the same as the width of the guide rod 803, and the guide rod 803 is connected to the first fixed rod 703... The push rod 801 is fixedly connected. The second push rod 804 has a cuboid shape and is clearance-fitted with the third hole 805. The second push rod 804 is fixedly connected to the first push rod 801, preventing it from rotating inside the third hole 805. This causes the guide rod 803 to move downwards along the guide groove 802, pushing the entire support rod 712 out of the second groove 702, completing disassembly. When installing the splicing box, rotating the fixing plate 716 causes the torsion spring 706 to store force. Rotating the fixing plate 716 then moves the limit rod 709 to... Inside the first hole 710, the support rod 712 is aligned with the inside of the second groove 702. The fixing plate 716 is released. When the limiting rod 709 moves to the position of the first hole 710, the torsion spring 706 drives the rotating plate 715 to return to its original position, which in turn drives the first fixing rod 703 to return to its original position. This pushes the limiting rod 709 to move into the inside of the first hole 710, completing the connection and limiting of the first splicing box 5 and the second splicing box 9. Compared with the existing technology, it is not necessary to rotate the threaded rod many times to complete the installation and disassembly. Only half a turn is needed to complete the installation and disassembly, thereby improving the efficiency of rubber replacement.
