Description

Technical Field

[0001] This utility model belongs to the field of sheath sealing performance testing technology, and in particular relates to a testing device for testing the sealing performance of sheaths. Background Technology

[0002] like Figure 7 The diagram shows a structural schematic of one type of protective sleeve in the prior art. Specifically, the protective sleeve has a central through hole and an annular groove on its outer periphery. In use, the protective sleeve can be fixed by the annular groove on the protective sleeve at the position of the mounting through hole on the automotive sheet metal. In order to ensure the sealing between the outer periphery of the protective sleeve and the sheet metal at the contact point and to prevent water leakage, the sealing performance of the protective sleeve needs to be tested during the production process.

[0003] Currently, when testing the sealing performance of a protective sleeve, a through-hole that matches the annular groove on the sleeve is typically made on a test plate. After the sleeve is secured to the test plate using the annular groove, the central through-hole of the sleeve is sealed. The test plate is then placed in a water tank, and the sealing performance of the sleeve is tested by immersion. However, in the existing technology, this setup requires both a fixing mechanism to secure the test plate in the water tank and a sealing structure to ensure the seal between the outer periphery of the test plate and the water tank. This is inconvenient during use, and therefore, the existing technology still has its shortcomings and deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for detecting the sealing performance of a sheath, thereby solving the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A testing device for detecting the sealing performance of a sheath includes a frame on which a water tank is mounted. The water tank has a box structure with an open top surface. A vertical observation port is provided on the bottom surface of the water tank. A horizontally distributed test plate is provided at the top of the observation port. The outer periphery of the test plate is located outside the observation port, and the outer periphery of the test plate is connected to the inner bottom surface of the water tank by sealing putty. A vertical through hole for placing objects is also provided on the test plate, which is opposite to the position of the observation port.

[0007] Furthermore, there are multiple observation ports, and each observation port is equipped with a test plate at its top. The outer periphery of each test plate is connected to the inner bottom surface of the water storage tank by sealing putty, and each test plate is vertically provided with the placement through hole.

[0008] Furthermore, each observation port is coaxially connected to a drain pipe with openings at both ends. The bottom end of each drain pipe is located below the water storage tank and is fitted with a sealed cap that is threaded onto it.

[0009] Furthermore, it also includes a material closing mechanism, which is equal in number to the observation port and positioned opposite each other. The material closing mechanism includes a support plate, which is connected to the water storage tank by a hanging rope. Two opposing guide shafts are installed at both ends of the support plate to form a U-shaped structure. The guide shafts are all threaded shafts, and a pressure plate is slidably sleeved between the two guide shafts. Locking rings are sleeved and threadedly connected on the guide shafts located on the side of the pressure plate away from the support plate.

[0010] Furthermore, the frame includes a horizontally arranged rectangular frame, the top surface of which has a receiving groove for accommodating the bottom of the water storage tank, and vertically opposite support legs fixedly connected to the four corners of the bottom surface of the rectangular frame. A bearing plate located below the rectangular frame is installed between the four support legs, and the bearing plate is arranged parallel to the rectangular frame.

[0011] Furthermore, a water outlet is provided on the bottom surface of the water storage tank, and a water outlet pipe with a switch valve is connected to the water outlet.

[0012] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] In use, this invention allows the sheath to be secured to the test plate via a ring-shaped slot through the through-hole. The test plate is then horizontally placed into the observation port of the water tank, with the sheath positioned within the tank. Sealing putty is then laid and compressed between the outer periphery of the test plate and the water tank, forming a ring around the test plate. This not only secures the test plate within the tank but also ensures a tight seal between the test plate and the tank, preventing water leakage at the contact point during testing. Compared to existing technologies, this invention is easier to use and reduces the number of components. Attached Figure Description

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 7 As shown, this utility model provides a testing device for detecting the sealing performance of a protective sleeve, including a frame 4, on which a water tank 3 is installed. The frame 4 is a frame structure that can be used to support the water tank 3. The water tank 3 is a box structure with an open top surface. A vertical observation port 31 is provided on the bottom surface of the water tank 3. A horizontally distributed test plate 2 is provided at the top of the observation port 31. The outer periphery of the test plate 2 is located outside the observation port 31, and the outer periphery of the test plate 2 is connected to the inner bottom surface of the water tank 3 by a sealing putty 1. A vertically opened object placement through hole 21 is also provided on the test plate 2, which is opposite to the position of the observation port 31. The object placement through hole 21 is adapted to the annular groove 91 on the protective sleeve 9 to be tested.

[0024] In use, the sheath 9 can be secured to the test plate 2 using the annular slot 91 through the through hole 21 on the test plate 2. Then, the test plate 2 can be horizontally placed into the water tank 3 at the observation port 31, ensuring the sheath 9 is inside the water tank 3. Next, sealing putty 1 can be laid and pressed between the outer periphery of the top surface of the test plate 2 and the water tank 3, forming a ring around the outer periphery of the test plate 2. This not only secures the test plate 2 within the water tank 3 but also ensures proper sealing between the outer periphery of the test plate 2 and the water tank 3. The sealing performance is ensured to prevent water leakage at the contact point between the test plate 2 and the water tank 3 during the test. Compared with the prior art, this method is easier to use and reduces the number of parts. After sealing the central through hole of the sheath 9, water can be added to the water tank 3 through the top opening until the contact point between the sheath 9 and the test plate 2 is completely submerged in water. Then, the water can be observed at the bottom of the water tank 3 through the observation port 31 to see if there is any water leakage at the contact point between the outer periphery of the sheath 9 and the test plate 2, so as to test the sealing performance of the sheath 9.

[0025] In addition, a water storage basin or other container can be placed below the observation port 31. After the test is completed, the test plate 2 can be removed by peeling off the sealing putty 1, and then the water in the water storage tank 3 can be drained into the water storage basin through the observation port 31. In addition, after removing the test plate 2, it is also convenient to replace the protective sleeve 9 on the test plate 2 for sealing test.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, there are multiple observation ports 31, and each observation port 31 has a test plate 2 at its top. The outer periphery of each test plate 2 is connected to the inner bottom surface of the water storage tank 3 by sealing putty 1, and each test plate 2 has a vertically opened through hole 21 for placing objects. In this way, the sealing performance of multiple protective sleeves 9 can be tested simultaneously during use; in addition, as Figure 2 As shown, the shape of the storage through hole 21 can be set to be circular or rectangular, and the size can vary, which makes it convenient to conduct sealing tests on sheaths 9 of different specifications and shapes.

[0027] Furthermore, such as Figure 3As shown, each observation port 31 is coaxially connected to a drain pipe 5 with openings at both ends. The bottom end of each drain pipe 5 is located below the water storage tank 3 and is fitted with a threaded sealing cap 6, meaning the sealing cap 6 is removable. During use, when testing the sealing performance of the sheath 9, even after removing the sealing cap 6, it is still possible to observe through the observation port 31 whether there is any leakage at the contact point between the outer periphery of the sheath 9 and the test plate 2. When the sealing cap 6 is installed on the drain pipe 5, it can prevent water in the water storage tank 3 from flowing out through the observation port 31 and the drain pipe 5 in sequence. Thus, during testing, one or more observation ports 31 can be selected arbitrarily to test the sealing performance of the sheath 9, making it more convenient to use.

[0028] Furthermore, such as Figure 1 and Figure 4 As shown, it also includes a material closing mechanism 7, which is equal in number and opposite in position to the observation port 31. The material closing mechanism 7 includes a support plate 71, which is connected to the water storage tank 3 by a hanging rope 72. Two guide shafts 73 arranged opposite each other are installed at both ends of the support plate 71 to form a U-shaped structure. The guide shafts 73 are all threaded shafts, and a pressure plate 74 is slidably sleeved between the two guide shafts 73. Locking rings 75 are threaded and sleeved on the guide shafts 73 on the side of the pressure plate 74 away from the support plate 71. The outer wall of the locking rings 75 is provided with protective grooves to facilitate the rotation of the locking rings 75 on the guide shafts 73. Specifically, the support plate 71, guide shafts 73, pressure plate 74 and locking rings 75 are connected in a U-shape. All tightening rings 75 can be made of rigid plastic. When it is necessary to seal the central through hole of the sheath 9 during use, the sealing mechanism 7 can be moved into the water tank 3. Then, the sheath 9 can be passed through the space formed by the U-shaped structure and the pressure plate 74. At this time, by sliding the position of the pressure plate 74 on the two guide shafts 73, the pressure plate 74 and the support plate 71 can jointly squeeze the sheath 9. Then, by rotating the locking ring 75, after the locking ring 75 and the pressure plate 74 are pressed together, the pressure plate 74 and the support plate 71 can jointly squeeze the sheath 9, thus sealing the central through hole of the sheath 9. Secondly, the sealing mechanism 7 can also facilitate the sealing of the central through hole of sheaths 9 of different specifications and shapes.

[0029] The specific setup method for rack 4 is as follows: Figures 1 to 3 As shown, the frame 4 includes a horizontally arranged rectangular frame 41. The top surface of the rectangular frame 41 is provided with a receiving groove for accommodating the bottom of the water storage tank 3. Vertically opposite support legs 42 are fixedly connected to the four corners of the bottom surface of the rectangular frame 41. A bearing plate 43 located below the rectangular frame 41 is installed between the four support legs 42. The bearing plate 43 is arranged parallel to the rectangular frame 41. Specifically, when using the water storage tank 3, the water can be discharged outward through the observation port 31, and containers such as water storage basins can be placed on the bearing plate 43.

[0030] Furthermore, such as Figure 2 and Figure 3 As shown, a water outlet 32 ​​is provided on the bottom surface of the water storage tank 3. A water outlet pipe 8 with a switch valve is connected to the water outlet 32. The switch valve can be used to open and close the water outlet channel in the water outlet pipe 8. When in use, after the sealing test of the sheath 9 is completed, the switch valve on the water outlet pipe 8 can be opened to discharge the water in the water storage tank 3 through the water outlet 32 ​​and the water outlet pipe 8. At this time, after the water is discharged, the sheath 9 on the test plate 2 can be replaced directly in the water storage tank 3. In addition, an extension hose can be connected to the end of the water outlet pipe 8 away from the water outlet 32 ​​so that the test water can be directly discharged into the sewer or directly discharged into the sewage treatment equipment for treatment and recycling.
