[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Figure 1-6As shown, this utility model provides a testing device for the toughness of building waterproof materials, including a body 1 and a testing device 6. A fixing frame 3 and a first clamping assembly 7 are fixedly installed on the upper surface of the body 1. A lifting rod 5 is slidably installed inside the fixing frame 3. A hydraulic tension rod 4 is fixedly installed at the top of the fixing frame 3, and the bottom end of the hydraulic tension rod 4 is fixedly connected to the top end of the lifting rod 5. A slider 10 is slidably installed inside the lifting rod 5. A lead screw 9 is rotatably installed inside the lifting rod 5, and the lead screw 9 is threaded into the slider 10. A knob 11 is fixedly installed at one end of the lead screw 9. The testing device 6 is fixedly installed at the bottom end of the slider 10. A second clamping assembly 8 is fixedly installed at the bottom end of the testing device 6. A protective assembly 2 is fixedly installed on the upper surface of the body 1. The protective assembly 2 includes a protective box 21. A door panel 22 is hinged to one side of the protective box 21. The door panel 22 is made of transparent material and a handle 23 is fixedly installed on the door panel 22. A touch control screen is installed on the body 1, which can be used to control the start of the device. The system allows for stopping and parameter adjustment, and the test data is displayed on the touch control screen. The testing device 6 is used to accurately measure the tensile force and displacement of the sample during the test. It typically includes sensors and data transmission devices. First, the first clamping component 7 clamps and fixes one end of the waterproof membrane sample, and the second clamping component 8 clamps and fixes the other end of the sample. As needed for testing, the knob 11 drives the slider 10 to slide within the lifting rod 5. The slider 10 moves one end of the sample to adjust the test point. Then, the hydraulic tension rod 4 drives the lifting rod 5 to slide and rise within the fixed frame 3. The lifting rod 5 performs toughness testing on the sample through the testing device 6 and the second clamping component 8. The testing device 6 transmits the test data to the touch control screen on the machine body 1 through the sensors and data transmission devices. During the test, the protective box 21 and the door panel 22 prevent the membrane from being thrown out and accidentally injuring the staff when it breaks. The door panel 22 is made of transparent material for easy observation by the testing personnel.
[0022] Both the first clamping assembly 7 and the second clamping assembly 8 include a fixing groove 81. A clamping plate 82 is slidably installed in each of the two fixing grooves 81. Two threaded rods 86 are symmetrically distributed and rotatably installed in each of the two fixing grooves 81, and the threaded rods 86 are threadedly inserted into the corresponding clamping plates 82.
[0023] By adopting the above technical solution, one side of the fixing groove 81 is at the same height as the clamping plate 82. The threaded rod 86 drives the clamping plate 82 to move in the fixing groove 81 to clamp and fix the end of the sample.
[0024] A drive shaft 83 is rotatably mounted on one side of each of the two fixed slots 81. A worm gear 84 is fixedly mounted on both ends of each of the two drive shafts 83. A worm wheel 85 is fixedly mounted on one end of each of the four threaded rods 86, and the worm wheel 85 meshes with the corresponding worm gear 84.
[0025] By adopting the above technical solution, the drive shaft 83 drives the worm 84 to rotate, the worm 84 drives the worm wheel 85 to rotate, and the worm wheel 85 drives the threaded rod 86 to rotate.
[0026] A limit rod 15 is slidably installed inside the door panel 22. A paddle 12 is fixedly installed at one end of the limit rod 15. A spring 13 is fixedly installed inside the door panel 22, and one end of the spring 13 is fixedly connected to one end of the limit rod 15. A limit groove 14 is opened on one side inside the protective box 21, and one end of the limit rod 15 can be inserted into the limit groove 14.
[0027] By adopting the above technical solution, the lever 12 can be turned, which drives the limiting rod 15 to move and retract into the door panel 22, and squeezes the spring 13, causing the limiting rod 15 to disengage from the limiting groove 14 on the protective box 21. Thus, the door panel 22 is released from the limit. The door panel 22 can be opened by the handle 23. After the door panel 22 is closed, the lever 12 is released, and the rebound force of the spring 13 causes one end of the limiting rod 15 to be inserted into the limiting groove 14, thus limiting the door panel 22.
[0028] Working principle: When using this utility model, firstly, the lever 12 is moved, which moves the limiting rod 15 and retracts it into the door panel 22, compressing the spring 13 and causing the limiting rod 15 to disengage from the limiting groove 14 on the protective box 21. This releases the door panel 22 from its limiting position, allowing it to be opened via the handle 23. Then, the first clamping assembly 7 clamps and fixes one end of the waterproof membrane sample, and the second clamping assembly 8 clamps and fixes the other end. Depending on the testing requirements, the knob 11 can be used to move the slider 10 along the lifting rod. The slider 10 moves one end of the sample to adjust the test point. Then, the hydraulic tension rod 4 drives the lifting rod 5 to slide and rise within the fixed frame 3. The lifting rod 5 performs toughness testing on the sample through the detection device 6 and the second clamping assembly 8. The detection device 6 transmits the test data to the touch control screen on the machine body 1 through the sensor and data transmission device. During the test, the protective box 21 and the door panel 22 can prevent the rolled material from breaking and accidentally injuring the staff. The door panel 22 is made of transparent material, which is convenient for the testers to observe.
[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
