Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to an airtightness testing device for wading trousers. Background Technology

[0002] Onesie wading trousers are waterproof garments made of waterproof fabric to ensure the comfort and safety of users when working in water. After production, onesie wading trousers require airtightness testing to prevent leaks during use. However, most current market methods use manual water testing, where an inflated onesie wading trouser is submerged in water; the appearance of air bubbles indicates a defect. However, during airtightness testing, if the waist opening is not completely sealed, air can escape, interfering with the test and increasing the error rate. Therefore, to address the shortcomings of current onesie wading trouser airtightness testing equipment in terms of airtightness and operability, a new airtightness testing device has been invented. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an airtightness testing device for wading pants.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An airtightness testing device for wading pants includes a testing chamber. Inside the testing chamber, arranged from bottom to top, are an air supply assembly, a clamping assembly, a second spray assembly, and a fixing assembly. The clamping assembly includes a double-piston rod cylinder, a cylinder piston rod, a first sealing plate, a second sealing plate, and a clamp. The second sealing plate is driven by the piston rod of the double-piston rod cylinder and fits against the first sealing plate. The fixing assembly includes a movable retaining ring, a cylinder, and a pneumatic rod. The cylinder drives the movable retaining ring to move up and down via the pneumatic rod. The air supply assembly includes an air pump and an air guide pipe. One end of the air guide pipe is connected to the air pump, and the clamp is located on the outer periphery of the air guide pipe. The second spray assembly includes a soap dish, a second spray nozzle, and a hose. The second spray nozzle is located inside the testing chamber and connected to the soap dish via the hose.

[0006] Preferably, the clamping assembly further includes a gripper located at the other end of the air duct, and the clamp is located below the gripper.

[0007] Preferably, a pressure gauge is provided on one side of the air guide tube.

[0008] Preferably, a buckle is provided on one side of the movable retaining ring, and a rubber pad is provided on the movable retaining ring.

[0009] Preferably, the detection chamber is provided with a spray assembly, which includes a water tank, a nozzle, and a spray pipe. The water tank is located on one side of the cylinder, and the nozzle is located inside the detection chamber and connected to the water tank through the spray pipe.

[0010] Preferably, the bottom of the detection box is provided with several casters.

[0011] Preferably, the detection chamber is provided with a door panel, and the door panel is provided with a door handle.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting a fixing component on the top of the testing chamber, the pant legs of the one-piece wading pants can be fixed to the movable buckle of the fixing component. The movable buckle can prevent the pant legs of the one-piece wading pants from loosening or falling off during the inflation process. Through the cooperation of the air supply component and the clamping component, the gripper opens the opening of the waistband of the one-piece wading pants and puts it downward on the outer periphery of the upper end of the air duct. Under the clamping of the clamp, the waistband of the one-piece wading pants is fixed to the outer periphery of the air duct. The air pump inflates the inside of the one-piece wading pants through the air duct. After inflation, the piston rod of the double piston rod cylinder drives the sealing plate one and sealing plate two to fasten, so that the waistband of the one-piece wading pants is reinforced and sealed, preventing the gas inside the one-piece wading pants from escaping from the waistband. Meanwhile, by spraying soapy water onto the air-filled onesie wading pants, bubbles will form on the surface of the onesie wading pants when the soapy water comes into contact with the leak, thus making it possible to directly detect the location of the leak, greatly improving the efficiency and accuracy of the detection.

[0014] 2. By adding water into the water tank, the water will flow through the spray pipe to the first spray nozzle, which will spray water onto the surface of the one-piece wading pants to wash away the soapy water. Attached Figure Description

[0028] like Figures 1 to 8 As shown, an airtightness testing device for wading pants includes a testing chamber 1. The testing chamber 1 has, from bottom to top, an air supply component 2, a clamping component 3, and a fixing component 5. The air supply component 2 includes an air pump 21 and an air guide pipe 22. One end of the air guide pipe 22 is connected to the air pump 21, supplying air into the air guide pipe 22. The other end of the air guide pipe 22 passes through a partition inside the testing chamber 1, and the air pump 21 inflates the one-piece wading pants through the air guide pipe 22. Furthermore, a pressure gauge 4 is installed on one side of the air guide pipe 22. Inflation is stopped by observing the pressure gauge reading. This operation not only completes the test in a short time, saving time and effort, but is also less affected by external environmental factors and operational differences, thereby improving the accuracy and reliability of the test.

[0029] refer to Figure 2 , Figure 7 As shown, a clamping assembly 3 is disposed above the air supply assembly 2. The clamping assembly 3 includes a double piston rod cylinder 31, a cylinder piston rod 311, a first sealing plate 32, and a second sealing plate 33. The double piston rod cylinder 31 is installed horizontally, which ensures stable operation and achieves optimal sealing between the one-piece waders and the sealing plate. Furthermore, the first sealing plate 32 is fixedly connected to the double piston rod cylinder 31, which provides clamping power. The second sealing plate 33 is driven by the cylinder piston rod 311 to fit against the first sealing plate 32. When the double piston rod cylinder 31 operates, the second sealing plate 33 achieves clamping and sealing of the waistband of the one-piece waders by reciprocating motion driven by the double piston rod cylinder 31. The sealing plate 33 is provided with a cross support 331, and the cross support 331 is bent. The bending treatment can effectively prevent the cross support 331 from being subjected to excessive force in the middle, which would lead to uneven sealing effect. That is, the bending treatment increases the effective running distance of the cylinder piston rod 311 in the clamping process.

[0030] Furthermore, a clamp 34 is provided at the upper end of the air duct 22. The clamp 34 can open the opening of the waistband of different models of one-piece wading pants and fit the waistband of the one-piece wading pants onto the outer periphery of the upper end of the air duct 22, so that the air duct 22 is precisely inserted into the opening of the waistband of the one-piece wading pants. Below the clamp 34, a clamp 35 is provided to cooperate with the clamp 34. The clamp 35 is divided into two connecting blocks 351. The connecting ends of the two connecting blocks 351 are screwed together by bolts 353 to tighten the clamp 35. When the clamp 35 locks the upper end of the air duct 22 and the opening of the waistband of the one-piece wading pants, the connecting blocks 351 at both ends of the clamp 35 are pulled closer by the bolts 353, while the hinge 352 on the other side locks the connecting block 351 to the outer periphery of the upper end of the air duct 22, thereby achieving the sealing and fixation of the waistband of the one-piece wading pants.

[0031] refer to Figure 2 , Figure 4 As shown, a fixing component 5 is provided above the clamping component 3. The fixing component 5 includes a movable retaining ring 51 and a cylinder 52. The cylinder 52 is connected to a pneumatic rod 53, which passes through the top of the detection box 1. The telescopic end of the pneumatic rod 53 is connected to a connecting plate 54. The movable retaining ring 51 is symmetrically fixed below the connecting plate 54. The pneumatic rod 53 can be adjusted up and down according to different models of one-piece wading pants. A buckle 512 is provided on one side of the movable retaining ring 51. The buckle 512 can fasten the movable retaining ring 51 to fix the pant legs of the one-piece wading pants, preventing the pant legs from loosening or falling off during inflation. A rubber pad 511 is provided on the movable retaining ring 51. The rubber pad 511 can effectively reduce the friction between the pant legs of the one-piece wading pants and the movable retaining ring 51, preventing the pant legs from being damaged and causing the air inside the one-piece wading pants to escape. When the leg opening of the onesie wading pants is suspended on the movable retaining ring 51, the cylinder 52 drives the pneumatic rod 53 to adjust the movable retaining ring 51 up and down, thereby facilitating the hanging of the onesie wading pants by the staff and allowing the height to be adjusted according to different models of onesie wading pants; in addition, the movable retaining ring 51 is fastened to the leg opening of the onesie wading pants by the buckle 512, thereby securing the onesie wading pants to the movable retaining ring 51. That is, the fixing component 5 greatly improves the work efficiency of airtightness testing, as well as the convenience and adaptability of airtightness testing.

[0032] refer to Figure 1 , Figure 2As shown, spray assembly 7 is installed on both sides of the detection box 1. Spray assembly 7 includes a soap container 71 and a spray nozzle 72. The soap container 71 is located on both sides of the detection box 1. A support plate 711 is provided at the bottom of the soap container 71 to fix the soap container 71. A hose 73 is connected to the soap container 71. The spray nozzle 72 is connected to the soap container 71 through the hose 73 and is located inside the detection box 1. The soap water in the soap container 71 flows to the spray nozzle 72 through the hose 73. The spray nozzle 72 sprays soap water onto the air-filled one-piece waders. When the soap water comes into contact with the air leak point, the gas escapes from the air leak point, causing the soap water to form bubbles. As a result, bubbles will form at the air leak point on the surface of the one-piece waders, thus allowing for direct detection of the air leak location, greatly improving the detection efficiency and accuracy.

[0033] Furthermore, a spray assembly 6 is provided on one side of the fixing component 5. The spray assembly 6 includes a water storage tank 61 and a nozzle 62. The water storage tank 61 is located at the top of the detection box 1 and on one side of the cylinder 52. A cover plate 612 is provided on the water storage tank 61 to prevent dust or dirt in the air from contaminating the water in the water storage tank 61. Several connecting posts 611 are provided between the bottom of the water storage tank 61 and the top of the detection box 1. The connecting posts 611 perpendicular to the detection box 1 can strengthen the connection and further improve the stability of the water storage tank 61. In addition, the nozzle 62 is connected to the water storage tank 61 through a spray pipe 63 and is located inside the detection box 1. In use, the cover plate 612 of the water storage tank 61 is opened to add water into the water storage tank 61, and the water flows to the nozzle 62 through the spray pipe 63. After the soapy water is sprayed, the nozzle 62 can rotate to spray water into the inside of the detection box 1, thereby washing away the soapy water on the onesie wading pants.

[0034] refer to Figure 8As shown, when testing the airtightness of the onesie wading pants, firstly, the pant legs of the onesie wading pants are vertically fixed to the movable retaining ring 51. After fastening the movable retaining ring 51, the clamp 34 opens the opening of the waistband of the onesie wading pants and places the waistband downwards onto the outer periphery of the upper end of the air duct 22. The waistband of the onesie wading pants is fixed to the outer periphery of the upper end of the air duct 22 by the clamp 35, so that the upper end of the air duct 22 is inserted into the waistband of the onesie wading pants. The clamp 35 fastens the waistband of the onesie wading pants to the upper end of the air duct 22, which is convenient for inflating different models of onesie wading pants. Then, the air pump 21 inflates the inside of the onesie wading pants through the air duct 22. Observe the pressure gauge 4 and stop inflating after reaching the target value. At this time, the onesie wading pants will inflate. After inflation, the pant legs of the onesie wading pants will easily turn outwards and tightly fasten the movable retaining ring 51. Subsequently, sealing plate 33, driven by the piston rod 311 of the double piston rod cylinder 31, tightly adheres to sealing plate 32, thereby reinforcing and sealing the waistband of the one-piece wading pants to prevent air from escaping from the waistband. Finally, spraying soapy water onto the inflated one-piece wading pants using nozzle 72 causes bubbles to form on the surface of the leak when the soapy water comes into contact with it, allowing for direct detection of the leak location. After spraying soapy water, nozzle 62 rotates and sprays water around the one-piece wading pants to wash away the soapy water. Monitoring the presence of bubbles on the surface of the one-piece wading pants determines their airtightness. If bubbles appear on the surface of the inflated one-piece wading pants, their airtightness is deemed unqualified; conversely, if no bubbles appear, their airtightness is deemed acceptable.

[0035] refer to Figure 1 As shown, the testing chamber 1 is equipped with a door panel 12, and a door handle 121 is provided on the door panel 12, which facilitates opening and closing the door panel 12 of the testing chamber 1. In addition, four casters 11 are installed at the bottom of the testing chamber 1 to facilitate the movement and adjustment of the testing device. The tires of the casters 11 are made of TPE material, which provides a quiet and wear-resistant effect. Therefore, the use of the door handle 121 and the casters 11 improves the flexibility and ease of use of the testing equipment.
