Trampoline tension spring tensile test equipment

Abstract

The invention relates to a trampoline extension spring tension test equipment, which comprises a frame, the two ends of the upper part of the frame are respectively provided with a fixed ring and a fixed pulley block, one end side of the frame is provided with a reversing pulley, and the lower part of the frame is provided with Pulling rope winding device, the fixed ring is fixed with a tension indicator, and the pulling rope on the fixed pulley block successively bypasses the moving pulley set on the frame and the reversing pulley on one side of the frame, and then connects with the pulling rope winding device at the lower part of the frame. connect. During the test, hang the tension spring sample between the tension indicator and the movable pulley, turn the handle to drive the rope shaft to rotate, the rope is wound on the rope shaft under force, and the movable pulley block pulls the tension spring to extend to the specified length. Read the value of the tension indicator. Let go of the rocking handle, and the rocking handle and the pull rope shaft will not reverse under the action of the ratchet. When the extension spring needs to be played back, the pawl is lifted, and the entire dynamic system will retract under the action of the extension spring restoring force, the extension spring sample is removed, and the next extension spring sample is replaced.

Description

technical field [0001] The invention relates to a sports equipment test equipment, in particular to an energy-saving and labor-saving trampoline extension spring test equipment. Background technique [0002] There are many extension springs installed between the mesh surface and the frame on the trampoline. These extension springs must ensure sufficient elastic properties within a certain stretch range, and must ensure that there is only elastic deformation without the slightest plastic deformation. The tension spring is subjected to a tensile test several times the natural length of the spring body to ensure that the above requirements are met. Otherwise, the mesh surface will drop and the elasticity will be insufficient during the athlete's use. What's more serious is that the mesh surface may touch the ground when the athlete makes a big move, causing terrible injuries to the athlete. Therefore, it is particularly important to inspect the trampoline extension spring to e...

Problems solved by technology

However, due to the particularity of the detection of trampoline extension springs, there is no special detection equipment on the market at present. It is labor-intensive and labor-intensive to replace it with ordinary detection equipment, and the detection effect is not ideal.
