Description

Technical Field

[0001] This utility model relates to the field of plastic running track technology, specifically a modular plastic running track. Background Technology

[0002] Synthetic running tracks, also known as all-weather athletic tracks, are sports fields made of plastic or rubber. They are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. Synthetic running tracks are characterized by good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and injuries. Composed of polyurethane rubber and other materials, synthetic running tracks possess a certain degree of elasticity and color, and have a certain degree of UV resistance and aging resistance, making them internationally recognized as the best all-weather outdoor sports flooring material.

[0003] For example, Chinese Patent Publication No. CN217298511U belongs to the field of plastic running track technology, and in particular, it is a modular plastic running track, including connecting block a and connecting block b. The right side of the connecting block a has a slot, and the inner wall of the slot engages with the outer surface of the slot. The connecting block a and connecting block b are connected by engaging the slot on the right side of the connecting block a with the slot on the left side of the connecting block b. At the same time, more modules can be assembled and connected by engaging the slot on the left side of the connecting block b and the slot on the right side of the connecting block b. After the connecting blocks a and b are assembled, they are fixed to the foundation by fixing columns passing through the connecting holes a and b. This solves the problems of long construction cycle, inconvenience for rapid laying, inability to disassemble existing devices, and easy waste of resources after use in infrequent temporary occasions.

[0004] After using the modular plastic running track, it was found that although it solves the problems of long construction cycle, inconvenience in quick installation and inability to disassemble existing devices, and the potential for resource waste when used in infrequent temporary locations, if a connecting block is damaged and needs to be replaced, the block is connected to four nearby connecting blocks because the locking block is stuck in the slot, making replacement inconvenient and limiting its practicality. Utility Model Content

[0005] The purpose of this invention is to provide a modular plastic running track to solve the problem that it is inconvenient to replace a certain connecting block.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular plastic running track, comprising connecting blocks, a base plate between the connecting blocks, a screw rotatably connected to the upper part of the base plate, a movable block connected to the external thread of the screw, a connecting strip rotatably connected to the side of the movable block, a rotating block rotatably connected to the upper part of the base plate, the connecting strip rotatably connected to the rotating block, an mounting plate fixedly connected to the side of the connecting blocks, a protrusion fixedly connected to the top of the mounting plate, a protruding strip fixedly connected to the inside of the connecting blocks, a groove formed at the bottom of the protruding strip, and the protrusion engaging with the groove.

[0007] Preferably, the protrusion contacts the base plate and the mounting plate.

[0008] Preferably, the surface of the mounting plate has through mounting holes.

[0009] Preferably, the upper part of the connecting block is provided with a through hole.

[0010] Preferably, the through hole is directly above the screw.

[0011] Preferably, the upper surface of the convex strip is flush with the upper surface of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves a downward-moving connecting block and a downward-moving groove, allowing the protrusion to engage with the groove. By using a socket wrench to turn the screws, the moving block moves downward, the connecting strip moves, and the rotating block rotates on the base plate. When the rotating block rotates 90 degrees, it presses against the protrusion, preventing further screw rotation and fixing the connecting block in place. If a connecting block is damaged, simply use a socket wrench to turn the eight screws corresponding to that connecting block to release the restriction, allowing the connecting block to be moved upward for easy replacement.
