And in the tensile test process of the rubber strips 19, the surface of each rubber strip 19 is carefully changed through the auxiliary observation assembly, so that the tensile capacity of each rubber strip 19 can be better distinguished by the staff, and the specific use flow of the auxiliary observation assembly is as follows: the staff sees the meticulous change of the surface of each rubber strip 19 from the magnifying glass 35 through the observation window 32 to accessible control panel 31 control limit lifting mechanism goes up and down to the magnifying glass 35, thereby conveniently carry out comprehensive observation to the rubber strip 19, and limit lifting mechanism's concrete operation process is, rotating electrical machines 38 operation drives second lead screw 39 rotation, and limit lifting piece 36 goes up and down in lift groove 37 along second lead screw 39, and then drives strip plate 33 and magnifying glass 35 and goes up and down.
It should be noted that, through the baffle 5 that sets up can separate each rubber strip 19 that carries out tensile test to make each rubber strip 19 mutually independent mutually noninterfere, avoid the tensile test of other rubber strips 19 around the rubber strip 19 of stretching out, in addition, set up hot plate 27 on baffle 5 and can build a relative temperature environment for each rubber strip 19, the tensile ability of convenient observation rubber strip 19 under different temperatures.
After the test of the rubber strip 19 is completed, the lifting driving mechanism operates again to drive the rubber fastener below to rise to the top point, the rubber strip 19 is not stretched any more, the spring column 10 releases elastic potential energy to push the diaphragm 9 and the lifting ring 16 upwards until the upper fastening seat 11 is propped against the bottom end surface of the sleeve 7, the first strong magnetic ring 12 and the second strong magnetic ring 13 are magnetically adsorbed together, then the control panel 31 controls the winch 29 to pay out the steel wire rope 30, the rotating plate 4 is turned outwards to be flat, in the process, the lifting ring 16 slowly breaks away from the hook 18, finally, the rubber strip 19 after the test is completed is taken down, and a new rubber strip 19 to be tested is put into the next round of tension test.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention.
