Description

Technical Field

[0001] The utility model relates to the technical field of rubber products, in particular to an integrated compression and tension detection device. Background Art

[0002] With the development of industry, various rubber products have played an increasingly important role in our lives. Before mass production of each rubber product, it is necessary to conduct tensile tests on the test products in the rubber product to ensure the tensile strength of the rubber product.

[0003] For this purpose, the China Patent Network has distributed a rubber product tensile testing device, with the announcement number CN210719924U, which includes an L-shaped mounting bracket, a connecting rod, a base and a support block. An L-shaped mounting bracket is installed at the middle position of one side of the top of the base, and an electric pneumatic cylinder is installed at the top of the L-shaped mounting bracket. The two sides of the bottom of the output end of the electric pneumatic cylinder are symmetrically hinged with connecting rods. A slide groove is provided on the side of the top of the base close to the L-shaped mounting bracket, and a sliding block is provided inside the slide groove. A movable mounting block is installed on the top of the sliding block. The side of the top of the movable mounting block close to the L-shaped mounting bracket is hinged to the bottom end of the connecting rod. The overall design of the utility model is in the form of horizontal tensile testing of rubber products. In conjunction with the support block installed on the top of the base, compared with the current vertical tensile testing, it avoids the influence of the gravity of the rubber product itself on the tensile testing results to a certain extent, and improves the accuracy of the device for tensile testing of rubber products.

[0004] However, there are still the following disadvantages: the device fixes the rubber product by flipping the clamp during the tensile test, but the rubber product itself has strong elasticity. Clamping it with the clamp during the tensile test may cause one end of the rubber product to fall off, which may be dangerous. Therefore, an integrated compression and tensile testing device is proposed. Utility Model Content
