How we make a nice and cheap air track gym mat

The utility model relates to an inflatable gym mat for sports, which comprises a gymnastic mat body, the gymnastic mat body is in a cuboid structure, the gymnastic mat body is made of a double-layer PVC middle clip mesh cloth through a sewing and heat closing, the side of the gymnastic mat body is provided with an air filling hole, the air filling hole is fixed with a valve, the valve includes a valve body and is connected with the thread of the valve body The valve body includes a cylindrical valve tube and a valve. The valve tube is provided with a through hole along its height. The valve includes a baffle plate fixed at the lower part of the through hole side wall, a blocking structure above the baffle plate, a spring fixedly connected with the upper surface of the baffle plate and between the baffle plate and the blocking structure, and a through hole side A vent hole on the wall, the plugging structure includes a plug block fixedly connected with the spring at the bottom and a thimble fixedly connected with the top of the plug block, the plug block is columnar, tangent to the vent hole, and can slide in the vent hole, the thimble extends outside the vent hole, when the thimble is free of external force, the plug block blocks the vent hole, when the thimble is pressed The cover cap is provided with a groove for holding the thimble.

The utility model adopts the technical scheme, and the double-layer PVC clamp grid is made of the inflatable gymnastics mat body through the sewing and heat sealing, which can improve the tension of the gymnastics mat and extend the service life of the gymnastics mat. The spring has a service life. If the spring is continuously compressed and stretched, it will lose its elasticity. The utility model sets the vent hole on the side of the vent hole, so that the instantaneous pressure increased in the vent hole when the athlete moves on the gymnastics pad will not be directly used on the spring. At the same time, there is a baffle at the bottom of the vent hole, which prevents the immediate pressure from acting directly On the spring, it can avoid the spring stretching continuously because of the athlete's movement on the gymnastic mat, and then shorten the life of the spring, resulting in the poor air tightness, so that the gymnastic mat can be used for a long time.
