Description

Technical Field

[0001] This utility model relates to the field of sports field paving technology, specifically a quick-installation connection structure for interlocking rubber running tracks. Background Technology

[0002] Rubber running tracks are sports field materials made primarily of natural or synthetic rubber. They are characterized by wear resistance, slip resistance, and good elasticity, and are widely used in the construction of athletic fields in schools, stadiums, parks, and other locations. Interlocking rubber running tracks are installed by splicing together multiple prefabricated components. Each component is joined together using specific connection methods (such as mechanical or adhesive connections) to form a complete track. These tracks are characterized by convenient installation, easy maintenance, and strong adaptability, making them suitable for various sites and different needs.

[0003] Currently, most interlocking rubber running tracks use adhesive connections. When a single rubber track is damaged and needs to be replaced, the adhesive must be removed before the track can be disassembled, which is quite troublesome. After replacement, adhesive needs to be applied again for fixation, making the replacement process very inconvenient. Therefore, we propose a quick installation and connection structure for interlocking rubber running tracks. Utility Model Content

A lower slot is provided on the outer wall of the rubber running track unit below the upper pin, and the lower slot cooperates with the lower pin. An upper slot is provided on the outer wall of the rubber running track unit above the lower pin, and the upper slot cooperates with the upper pin. A snap-fit ​​hook portion is provided on the upper surface of the upper and lower pins. A snap-fit ​​hook groove is provided on the upper surface of the lower and upper slots, and the snap-fit ​​hook groove cooperates with the snap-fit ​​hook portion. A fixed base is provided below the rubber running track unit.

Since the outer side wall of the rubber track unit 1 is provided with upper pin 2 and lower pin 3 respectively, and is provided with lower slot 4 and upper slot 5 corresponding to the upper pin 2 and lower pin 3.

[0026] During assembly, the upper pin 2 on the outer wall of the rubber track unit 1 is inserted into the upper slot 5 on the outer wall of the adjacent rubber track unit 1, and the lower pin 3 on the outer wall of the rubber track unit 1 is inserted into the lower slot 4 on the outer wall of the adjacent rubber track unit 1. After insertion, the material deformation of the upper pin 2 and the lower pin 3 achieves bidirectional locking. The snap-fit ​​hook part 6 on the upper surface of the upper pin 2 and the lower pin 3 snaps into the snap-fit ​​hook groove 7 on the upper surface of the lower slot 4 and the upper slot 5, so that the adjacent rubber track units 1 are connected and fixed. This design adopts a snap-fit ​​connection method, which makes the rubber track easy to assemble and disassemble.

After insertion, bidirectional locking is achieved through the material deformation of the upper pins 2 and lower pins 3. The engaging hook parts 6 on the upper surfaces of the upper pins 2 and lower pins 3 engage with the engaging hook grooves 7 on the upper surfaces of the lower slots 4 and upper slots 5, thus connecting and fixing the adjacent rubber track units 1. This design employs... The plug-in connection method makes the rubber track easy to assemble and disassemble. Furthermore, the first friction ridge layer 10 on the lower surface of the upper pin 2 and the lower pin 3 rubs against the second friction ridge layer 11 on the lower surface of the lower slot 4 and the upper slot 5, increasing the friction between them and providing good anti-displacement and anti-loosening effects. Then, the positioning pin 15 at the bottom of the rubber track unit 1 is inserted into the mounting hole 14 at the top of the fixed base 12, and the positioning pin 15 is pressed to make the locking part 16 elastically deform and lock into the mounting groove 13, thus fixing the rubber track unit 1 on the fixed base 12. This prevents the rubber track unit 1 from shifting and improves the stability of the rubber track. In addition, the positioning pin 15, the locking part 16, the upper pin 2, and the lower pin 3 are made of a mixture of nylon 66 and glass fiber, which enhances the tensile strength.
