[0001] The utility model relates to a waterproof testing device, in particular to a waterproof testing device for the production of sealing strips, belonging to the technical field of sealing strip production. Background Technique

[0002] A sealing strip is a product that seals something to make it not easy to open and plays roles such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention and fixing. Sealing strips are made of various materials such as rubber, paper, metal and plastic. During the production process of sealing strips, a waterproof testing device is usually required to test their waterproof performance.

[0003] According to the patent with the patent number CN218002884U, a waterproof testing device for the production of sealing strips is disclosed, including a water tank. One side of the top of the water tank is rotatably installed with a rope winding wheel, on which a pulling rope is wound. The two ends of the pulling rope are respectively fixedly installed with a pedal and a counterweight plate. The pedal is slidably connected to one side of the water tank, and the counterweight plate is slidably connected to the inner wall of one side of the water tank. A connecting plate is rotatably installed inside the counterweight plate.

[0004] During the implementation of the above solution, the workpiece with the sealing strip to be tested can be immersed below the water surface and reciprocally swung for waterproof testing. However, during the implementation of the above solution, it is difficult to stably clamp the sealing strip during the testing process. Due to the large buoyancy of the sealing strip, during the immersion test, it is mostly necessary for the tester to hold the sealing strip by hand for testing, increasing the working intensity of the tester. Therefore, we provide a waterproof testing device for the production of sealing strips to solve the above problems. Content of the Utility Model

[0008] Preferably, a placement groove is formed on the top surface of the clamping plate, a discoloring sticker is arranged inside the placement groove, and a sealing strip is slidably connected inside the placement groove. The discoloring sticker can chemically react with water, thereby causing a color change.

[0009] Preferably, an electric slide rail is formed on the top surface of the test box, a slider is slidably connected inside the electric slide rail, and a fixed pipe is arranged above the slider. When the slider slides inside the electric slide rail, it can drive the fixed pipe to move.

[0010] Preferably, a fixing ring is fixedly connected to the top surface of the slider, the fixing ring is adapted to the fixed pipe, and a flushing nozzle is fixedly communicated with the end of the fixed pipe. The movement of the fixed pipe can drive the flushing nozzle to perform multi-directional flushing waterproof testing on the sealing strip.

[0025] The embodiment of the present utility model provides a waterproof testing device for the production of sealing strips.

[0026] Please refer to Figure 1 , which includes a test box 1. A certain volume of water is contained inside the test box 1, facilitating the device to immerse the sealing strip 4 in water to complete the immersion waterproof testing operation of the sealing strip 4. An observation window made of glass is installed on the front of the test box 1, facilitating the tester to grasp the internal testing situation of the test box 1 in real time. Concave-shaped handles are installed on both sides of the test box 1, facilitating the personnel to carry the device.

[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 , an electric slide rail 5 is provided on the top surface of the test box 1. A slide block 6 is slidably connected inside the electric slide rail 5. The electric slide rail 5 is a prior art, and not too much description is given to it in this application. The electric slide rail 5 can control the slide block 6 to slide inside it, thereby changing the position of the slide block 6, enabling the slide block 6 to perform multi-directional flushing tests on the sealing strip 4 and improving the testing effect of the device.

[0028] Above the slider 6, there is a fixed pipe 7. The end of the fixed pipe 7 is fixedly connected and communicated with a flushing nozzle 9. The flushing nozzle 9 can perform a stamping waterproof test on the sealing strip 4, enabling the device to perform multiple tests and avoiding the single test method of immersion from affecting the test accuracy.

[0029] The top surface of the slider 6 is fixedly connected with a fixing ring 8. The fixing ring 8 is adapted to the fixed pipe 7. When the slider 6 moves inside the electric slide rail 5, it can drive the fixed pipe 7 to move, thereby changing the flushing position of the flushing nozzle 9 and increasing the flushing area of the flushing nozzle 9. The fixing ring 8 can fix the fixed pipe 7, enabling the fixed pipe 7 to remain stable during the movement.

[0030] Please refer to Figure 3 , outside the test box 1, a water pump 10 is fixedly installed. Above the water pump 10, there is a connecting hose 11. The two ends of the connecting hose 11 are respectively fixedly connected and communicated with the water pump 10 and the fixed pipe 7. The water pump 10 is a prior art and will not be elaborated too much in this application. The water pump 10 can pump the water inside the test box 1 into the connecting hose 11 and transport it to the flushing nozzle 9 through the fixed pipe 7 for stamping test, realizing the recycling of water resources. The connecting hose 11 is a plastic hose and can change with the movement of the fixed pipe 7, providing conditions for the device to flush the sealing strip 4 in all directions.

[0031] The outer surface of the test box 1 is fixedly communicated with a drain pipe 12, and the outer surface of the test box 1 is fixedly communicated with a water inlet pipe 13. Through the settings of the drain pipe 12 and the water inlet pipe 13, it is convenient for the test personnel to control the water level inside the test box 1. A valve is installed on the drain pipe 12. The valve is a prior art and will not be elaborated too much in this application. The test personnel can control the discharge of the test water inside the test box 1 by rotating the valve.

[0032] Please refer to Figure 2 , on the inner bottom wall of the test box 1, an electric push rod 2 is fixedly connected. The electric push rod 2 is a prior art and will not be elaborated too much in this application. All the components inside the electric push rod 2 are waterproofed to prevent the immersion water from affecting the operation of the electric push rod 2. When the test personnel start the electric push rod 2, they can control the electric push rod 2 to lift and lower inside the test box 1, so that the sealing strip 4 clamped by the clamping mechanism 3 is immersed in water for waterproof test, avoiding the need for personnel to hold it for test operation.

[0033] Please refer to Figure 2 、 Figure 4 and Figure 5, inside the test chamber 1, there is a clamping mechanism 3 for fixing. The clamping mechanism 3 includes a clamping plate 301 fixedly connected to the electric push rod 2. On the top surface of the clamping plate 301, there is a placement groove 307. Inside the placement groove 307, there is a sealing strip 4 slidably connected. The shape of the placement groove 307 can be produced according to the shape of the sealing strip 4 to be actually tested, and it has a good fit with the sealing strip 4. When the sealing strip 4 is placed in the groove, it can prevent water from entering the placement groove 307 through the gap between the two.

[0034] Inside the placement groove 307, there is a color-changing sticker 308. The color-changing sticker 308 is a prior art and will not be elaborated too much in this application. The color-changing sticker 308 will change color when it encounters water, which is convenient for testers to judge the sealing performance of the sealing strip 4 by whether the color-changing sticker 308 changes color. If the color-changing sticker 308 does not change color after testing, it proves that the sealing performance of the sealing strip 4 is good. If the color-changing sticker 308 changes color, it proves that the sealing performance of the sealing strip 4 is insufficient.

[0035] On the top surface of the clamping plate 301, there are two support frames 302 fixedly connected. Inside each support frame 302, there is a lifting plate 303 slidably connected. On both inner walls of the support frame 302, there are cross-shaped chutes. The two ends of the lifting plate 303 are designed in a cross shape, which can effectively improve the stability of the lifting plate 303 sliding inside the support frame 302 and prevent the lifting plate 303 from tilting and affecting the use of the pressing insertion rod 305.

[0036] Inside each support frame 302, there is a lifting screw rod 306 threadedly connected. The two lifting screw rods 306 are respectively rotatably connected to the two lifting plates 303. Testers can control the lifting of the lifting plate 303 inside the support frame 302 by rotating the lifting screw rod 306, thereby driving the pressing insertion rod 305 to slightly squeeze the sealing strip 4 inside the placement groove 307, so that the sealing strip 4 can be stable in the placement groove 307 and avoid the sealing strip 4 floating to the upper layer of the soaking water due to buoyancy, affecting the soaking effect of the device.

[0037] Outside the support frame 302, there is a pressing insertion rod 305. On the outer surface of the pressing insertion rod 305, there is a handle, which is convenient for testers to insert the pressing insertion rod 305 into the jack 304 through the handle. The friction between the pressing insertion rod 305 and the jack 304 is relatively large. When the pressing insertion rod 305 is inserted into the jack 304, it can remain relatively stable with the jack 304.

[0038] A set of jacks 304 are provided inside each lifting plate 303. The pressing insertion rod 305 is slidably connected to the jacks 304. When the pressing insertion rod 305 is inserted into the two sets of jacks 304, the pressing insertion rod 305 can press the sealing strip 4 inside the placement groove 307 to a certain extent, so that the sealing strip 4 remains stable in the placement groove 307, avoiding the operation of manually immersing the sealing strip 4 in water required by the test.

[0039] Working principle: When a tester wants to conduct a waterproof test on the sealing strip 4, first place the sealing strip 4 in the placement groove 307, then insert the pressing insertion rod 305 into the jacks 304, and then rotate the lifting screw 306 to a suitable position so that the pressing insertion rod 305 can slightly press the top surface of the sealing strip 4, enabling the sealing strip 4 to be stably clamped. Then start the electric push rod 2, so that the electric push rod 2 drives the clamping plate 301 to descend. At this time, the sealing strip 4 will be immersed in water to complete the immersion waterproof test of the sealing strip 4. Then control the electric push rod 2 to lift the clamping plate 301 out of the water surface, and start the water pump 10. The water pump 10 can pump the immersion water inside the test box 1 to the flushing nozzle 9 through the connecting hose 11 and the fixed pipe 7, so that the flushing nozzle 9 flushes the sealing strip 4, realizing various waterproof test methods of the device for the sealing strip 4, improving the test accuracy of the device, and reducing the working intensity of the tester holding the sealing strip 4 for waterproof testing.
