[0003] The arm strength device in the fitness equipment is to exercise the pressure of the bending spring, and to test the bending pressure of the spring to classify the kilogram. The current spring tester cannot test the bending pressure of the spring. The machine for testing bending is three points The bending test machine cannot test the bending pressure of the spring. Since the spring is cylindrical and there may be a gap between the rings, displacement is easy to occur, and the fixing effect is not good. It is easy for the spring to pop up and hit the staff. It is inconvenient to use a large equipment such as a bending test machine when the processing effect is high

Abstract
The invention discloses a bending pressure tester for an arm spring. The structure comprises a base, a testing fixture, a pressing block, a display, a pressing bar, and a testing stand. The testing stand is fixed on the base, and is provided with the pressing bar. The display is mounted on the testing stand, and a pressing block is arranged under the display. The testing fixture is arranged underthe pressing block, and is fixed on the base. The testing fixture consists of a supporting plate, a sliding rail, a sliding block, a bracket, a fixture, a rear pole, and a front pole. The supporting plate is erected on the base, and the top of the supporting plate is inwardly concaved in a semicircular shape. The top of the supporting plate is provided with the semi-circular sliding rail, and twoends of the sliding rail are separately provided with sliding blocks. The front and rear sides of the sliding block are separately welded with the front pole and the rear pole. The invention has beneficial effects of preventing the spring from leaving a test equipment by laterally clamping and limiting the spring at the same time by means of four clips and pins, measuring the bending pressure of the spring by pressing down the pressing bar and gradually closing two ends of the spring on the curved sliding rail; the device is simple and convenient, and is easy to carry.
Description
technical field [0001] The invention relates to the field of testers, in particular to a bending pressure tester for springs of armrests. Background technique [0002] A spring is a mechanical part that uses elasticity to work. According to the nature of the force, it can be divided into tension springs, compression springs, torsion springs and bending springs. [0003] The arm strength device in the fitness equipment is to exercise the pressure of the bending spring, and to test the bending pressure of the spring to classify the kilogram. The current spring tester cannot test the bending pressure of the spring. The machine for testing bending is three points The bending test machine cannot test the bending pressure of the spring. Since the spring is cylindrical and there may be a gap between the rings, displacement is easy to occur, and the fixing effect is not good. It is easy for the spring to pop up and hit the staff. It is inconvenient to use a large equipment such as ...
