[0002] PVC artificial leather refers to polyvinyl chloride artificial leather (PVC leather), which is made by coating PVC resin, plasticizer, stabilizer and other additives on the fabric to make a paste, or laminating a layer of PVC film, and then processing it through a certain process. The product has high strength, easy processing and low cost. It can be used to make various bags, seat covers, linings, sundries, etc. However, it has poor oil resistance and high temperature resistance, and poor softness and feel at low temperatures.

[0003] PVC artificial leather needs to be tested before it leaves the factory. The testing process is: elasticity test, stretch test, toughness test, anti-aging test. During the stretch test, we need to fix the PVC artificial leather on the test device, but conventional testing devices manually fix and straighten the PVC artificial leather. Manual straightening will result in low test accuracy and increased labor costs. In addition, conventional methods only stretch the two ends of the PVC artificial leather, and the other two ends of the PVC artificial leather are not fixed and have no stretching force, which affects the results of the stretch test and is not comprehensive. Utility Model Content

[0004] The utility model aims to solve the problems that the existing conventional testing devices all fix and straighten the PVC artificial leather manually, the manual straightening will lead to low test accuracy and increase labor costs, and the conventional method is to only stretch the two ends of the PVC artificial leather, while the other two ends of the PVC artificial leather are not fixed and have no stretching force, resulting in that the result of the elasticity test is affected and is not comprehensive, and a PVC artificial leather test fixing device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A PVC artificial leather testing fixture comprises a workbench, the bottom end of the workbench is fixedly connected to evenly distributed columns, the outer walls of the columns are fixedly connected to support plates, the outer wall of the workbench is provided with a crank, the crank is connected to evenly distributed moving blocks through a moving structure, and the top of the moving block is provided with a clamping assembly.

[0007] Preferably, the movable structure includes a protrusion, a cross groove, a uniformly distributed lead screw, a bevel gear, a connecting column, a slider, and a stopper. The protrusion is slidably connected to the crank, the cross groove is arranged at the top of the workbench, and one end of the lead screw is rotatably connected to the inner wall of the cross groove.

[0008] Preferably, the bevel gear is fixedly connected to the other end of the lead screw, the bottom end of the connecting column is fixedly connected to the top end of the support plate, the top end of the slider is fixedly connected to the bottom end of the moving block, and the top end of the stop block is fixedly connected to the bottom end of the slider.

[0010] Preferably, the clamping assembly includes a hinge, a flip block, an adapter groove, and a bolt. The hinge is fixedly connected to the top of the moving block, the top of the flip block is fixedly connected to the hinge, the adapter groove is arranged at the top of the moving block, and the bolt is threadedly connected to the moving block.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the utility model is in use, after the PVC artificial leather is clamped on the circular ring-shaped moving block by the turning block and the bolt, the manual rotation of the crank handle drives the moving block to move backward at the same time to stretch the PVC artificial leather, which not only avoids the problem of low accuracy of manual stretching, but also solves the problem of stretching only at the two ends, thereby improving the accuracy of the test, greatly reducing the labor cost, and making the result of the elasticity test more comprehensive.
