[0002] Rainproof cloth is a kind of cloth specially designed for waterproofing, which is widely used for covering vehicles, ships, goods in factories and mines, outdoor tourism and other purposes. It has the characteristics of sun resistance, frost resistance, aging resistance, corrosion resistance, light weight, easy to fold and durable;

[0003] There are many different materials for rainproof cloth, including polyester, nylon, tape, oilcloth and plastic film. These materials have good waterproof properties and can effectively prevent rain from penetrating. In addition, modern rainproof cloth may also use high-tech materials such as polytetrafluoroethylene (PTFE) to provide better waterproof and breathable properties.

[0004] The fabric needs to be tested for tensile strength before leaving the factory. However, due to the flexibility of the fabric, most of the time, a strip of fabric is taken for strength testing. However, due to the increase in length, splashing will occur when it breaks, and the existing device does not have the positioning function, which makes it easy for the tension to be uneven when the fabric is fixed, thus affecting the accuracy of the test. Therefore, we need to make improvements on this. Summary of the invention

A connecting assembly is provided on the outer wall of one side of the slide 17 . The slider 18 can assist the slide 17 to flexibly move on the outer side of the two rails 19 .

[0026] The connecting assembly includes a connecting plate 16 fixedly arranged on the outer wall of one side of the slide 17, an L-shaped frame 4 is fixedly arranged on the outer wall of one side of the frame beam 2, a first hydraulic cylinder 5 is installed on the upper part of the L-shaped frame 4, the telescopic end of the first hydraulic cylinder 5 is connected to the connecting plate 16, the first hydraulic cylinder 5 is fixedly arranged on one side of the frame beam 2 through the L-shaped frame 4 for use, and the connecting plate 16 can drive the slide 17 to move flexibly, thereby prompting the extrusion assemblies to move away from or close to each other, so as to achieve the purpose of tensile force detection of the cloth, and the extrusion assembly includes a second hydraulic cylinder 6 fixedly arranged inside the support frame 10, the telescopic end of the second hydraulic cylinder 6 passes through the inside of the mounting plate 11 and is connected to the T-shaped frame 24, and the second hydraulic cylinder 6 can drive the T-shaped frame 24 to move forward and backward, thereby prompting the structure outside the T-shaped frame 24 to clamp the cloth.

[0030] The two ends of the outer side of the support frame 21 are fixedly provided with fixed shafts 29, and the outer sides of the two fixed shafts 29 are rotatably installed with rotating sleeves 30. The rotating connection of the rotating sleeves 30 can make the barrier 14 tilt toward one end, and then press against the outer side of the frame 31. Due to the tilting of the barrier 14, when the fabric is stretched, it can cover the upper surface of the fabric, so that after the fabric breaks, the outer side of the fabric can be buffered and protected. The outer sides of the two sets of rotating sleeves 30 are fixedly provided with limit rods 13, and the two limit rods A sleeve rod 26 is slidably installed on the upper outer side of 13, and a barrier 14 is commonly set between the two sleeve rods 26.

[0031] Working principle: When in use, the cloth cut into strips is placed on the upper end surface of the positioning plate 3, and then the two ends of the cloth are placed between the two sets of abutment frames 31. Under the telescopic drive of the second cylinder 33, the U-shaped block 9 at the telescopic end is driven away from the two ends. Under the guidance of the two sets of abutment frames 31 and the guide wheel 34 at the lower end, the cloth moves to the support frames 21 at the two ends on the same horizontal plane. After passing through the support frame 21, the cloth contacts the inner surface of the U-shaped seat 20. With the assistance of the worker, the cloth is positioned, and then the guide wheel 34 and the abutment frame 31 are withdrawn to the outside of the support frame 21. Then, the first cylinders 25 located at both ends of the support frame 21 drive the abutment plate 35 to move, causing the induction clamp 22 to gradually approach the top of the cloth. Driven by the second hydraulic cylinder 6, the overall external structure of the T-shaped frame 24 is forced to approach one side of the mounting plate 11, so that the induction clamp 22 is pressed against the cloth. After completion, the barrier 14 is tilted to one end, causing the edge of the barrier 14 to tilt and abut against the outer side of the abutment frame 31. During the tensile test, after the cloth is broken, the impact force of the splash can be weakened, thereby ensuring safety during the tensile strength test.
