The invention discloses a spiral spring pulling device for a tension tester. The device comprises a push-pull pipe, a plurality of inserting grooves are formed in the side portion of the push-pull pipe, push-pull plates are inserted into the inserting grooves, a plurality of lock grooves are formed in the push-pull pipe, and the lock grooves are communicated with the inserting grooves; a pluralityof lock holes are formed in the inner side of the push-pull plate, the lock holes are communicated with the lock grooves, lock rods are inserted into the lock holes and the lock grooves, lock nuts are arranged at one ends of the lock rods, the lock nuts are locked to one sides of the push-pull pipes, lock caps are arranged at the other ends of the lock rods, and the lock caps are locked to the other sides of the push-pull pipes; a first inserting hole is formed in the side wall of the end of the push-pull pipe, a second inserting hole is formed in the side wall of the end of the inserting pipe, the second inserting hole is communicated with the first inserting hole, and an inserting shaft is inserted into the second inserting hole and the first inserting hole; a plurality of locking grooves are formed in the inner side parts of the push-pull plates; and a plurality of hook grooves are formed in the inner side parts of the push-pull plates. According to the invention, the elasticity ofa spiral spring can be detected through the tension tester, and the detection efficiency is high.
Description
technical field [0001] The invention relates to a pulling device, in particular to a coil spring pulling device used for a tensile tester. Background technique [0002] Tensile tester is an instrument for tensile testing, mainly used for non-metallic materials such as tapes, rubber, plastics, sea / foam, waterproof materials, wires and cables, textiles, net ropes, non-woven fabrics, and metal wires, metal foils, metals, etc. Tensile, compression, bending, peeling, shearing, tearing tests on sheet metal and metal rods. The existing tension tester is inconvenient to pull the helical spring, and the detection efficiency of the elastic performance of the helical spring is low. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, so as to provide a plug-in tube that can be manually pulled. The plug-in tube pulls the push-pull plate through the push-pull tube, and the push-pull plate can conveniently pull the coi...
