Description

Technical Field

[0001] This utility model relates to the field of sealing performance testing technology, specifically a sealing performance testing device for pipe joint components. Background Technology

[0002] Water can easily get into the wall handrails inside the bathroom during use. Therefore, during the production of the handrail bends, the joint components are tested for sealing. Leaks at the pipe joint components are considered unqualified.

[0003] In existing technologies, the detection speed is slowed down when users inspect handrail bends, making it impossible to quickly identify whether the joint components of the bends are leaking.

[0004] To overcome the aforementioned shortcomings, a prior art Chinese patent (publication number CN219757638U) discloses a pipe sealing test device, including a fixed base, a U-shaped plate at the top and near the rear of the fixed base, a feeding mechanism at the top and near the front of the fixed base, a first hydraulic cylinder at the center of the top of the U-shaped plate, the end of the movable rod of the first hydraulic cylinder passing through the top of the U-shaped plate and fixedly connected to a first movable plate, a first positioning mechanism at the left end of the bottom of the first movable plate, and a second positioning mechanism at the right end of the bottom of the first movable plate. This pipe sealing test device clamps and fixes the pipe using the first and second positioning mechanisms, sealing both ends of the pipe. Air is injected into the pipe through an L-shaped air inlet pipe, and the first hydraulic cylinder moves the first movable plate up and down, placing the pipe into a water tank. When there is a crack in the pipe, air bubbles will be generated in the water tank, allowing the user to quickly identify whether the pipe is sealed.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, when users test the sealing performance of pipe joint components, they need to manually place the object to be tested in a water tank. After prolonged use, the staff's hands are easily soaked and peeled, which is not conducive to the use of the equipment. Furthermore, the recognition speed is slow and results cannot be obtained quickly. Utility Model Content

[0006] The purpose of this invention is to provide a pipe joint component sealing performance testing device to solve the problems mentioned in the background art, where users need to manually place the object to be tested in a water tank when testing the sealing performance of pipe joint components. After prolonged use, the hands of the staff are easily soaked and peeled, which is not conducive to the use of the device. In addition, the recognition speed is slow and the results cannot be obtained quickly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipe joint component sealing performance testing device, comprising a housing and a fixed column disposed inside the housing, wherein a lifting block is disposed inside the fixed column, and a placement platform is mounted on the upper end of the lifting block; a servo motor is mounted on the lower end of the fixed column, and a self-immersion mechanism is disposed on the upper end of the servo motor, wherein the self-immersion mechanism includes a threaded rod, and the lower end of the threaded rod is connected to the output end of the servo motor; a fixed plate is fixedly mounted on the lower end of the housing, and a detection facilitation mechanism is mounted on the surface of the fixed plate, wherein the detection facilitation mechanism includes a second airbag, and the lower end of the second airbag is mounted on the surface of the fixed plate.

[0008] Furthermore, the surface of the placement platform is provided with a limiting band, which is elastically set, and a drain outlet is connected to the right side of the housing.

[0009] Furthermore, the self-immersion mechanism also includes a baffle, the outer side of which is fixedly installed on the inner wall of the fixed column, and the fixed column is located below the lifting block, and the interior of the lifting block is threadedly connected to the surface of the threaded rod.

[0010] Furthermore, a sealing strip is fixedly installed on the inner wall of the upper end of the fixed column, and the inner side of the sealing strip is in contact with the surface of the lifting block.

[0011] Furthermore, the detection mechanism also includes a first airbag, the lower end of which is fixedly installed on the inner wall of the fixed column, and the upper end of which forms a pressing structure with the lifting block.

[0012] Furthermore, the outer side of the first airbag is connected to an air guide hose, and the outer side of the air guide hose passes through a fixing plate to connect to the second airbag, and the fixing plate is L-shaped.

[0013] Furthermore, a limiting rod is fixedly installed at the lower end of the housing, and a striking plate is installed through the surface of the limiting rod. The inner side of the striking plate is slidably connected to the fixed plate through a slider. The lower end of the striking plate is correspondingly set to the surface of the second airbag. A vibration spring is sleeved on the surface of the limiting rod, and the upper and lower ends of the vibration spring are installed between the housing and the striking plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When performing a sealing test on the joint components, after the handrail bend is processed, it is placed on the platform surface. By starting the servo motor at the bottom of the fixed column, the servo motor drives the threaded rod to rotate. When the threaded rod rotates, it can drive the lifting block connected to the thread on its surface. Under the limit of the fixed column, the height of the lifting block can be adjusted with the rotation of the threaded rod. During the test, the height of the handrail bend and the connecting parts can be adjusted, and continuous testing can be performed without the need for the staff to put their hands into the device, avoiding the peeling of hands from prolonged immersion in water, and improving the comfort of the staff.

[0016] Furthermore, before testing the joint components of the handrail bends, two handrail bends are installed using the joint components. After installation, both ends of the handrail bends are sealed. During the sealing test, the handrail bends are placed on the platform surface. When the handrail bends and joint components are submerged, air bubbles will be generated if there are gaps inside. This can be observed by the inspector's naked eye or captured by a high-speed camera. After the test is completed, the water inside the device is drained by opening the drain outlet, making it convenient for users to operate. The operation is simple and convenient.

[0017] 2. When the lifting block lowers the placement platform and the handrail bend and joint components are submerged in water, the lifting block presses the first airbag, causing the striking plate to strike the shell. Under the action of the vibration spring, the striking effect is improved, ensuring the efficiency of the striking. This allows the shell to vibrate, achieving the effect of vibration-assisted measurement, improving the efficiency of sealing detection, and quickly detecting whether the joint components of the handrail bend are leaking air. It is efficient and convenient. Attached Figure Description

[0025] 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.

[0026] Example 1: As Figures 1-3 The technical solution shown is a pipe joint component sealing test device. In order to solve the problem of inconvenience in use, it discloses: a housing 1 and a fixed column 2 set inside the housing 1, and a lifting block 3 is set inside the fixed column 2. A placement platform 4 is installed on the upper end of the lifting block 3. A limit band 5 is set on the surface of the placement platform 4 and the limit band 5 is elastically set. A drain outlet 9 is connected to the right side of the housing 1.

[0027] Before testing the joint components of the handrail bends, two handrail bends are installed using the joint components. After installation, both ends of the handrail bends are sealed. During the sealing test, the handrail bends are placed on the surface of the placement platform 4 and fixed by the elastic limiting band 5. As water is added inside the housing 1, when the handrail bends and joint components are submerged, air bubbles will be generated if there are gaps inside. These bubbles can be observed by the inspector's naked eye or captured by a high-speed camera. After the test is completed, the water inside the device is drained by opening the drain port 9, making it convenient for users to operate.

[0028] Example 2: Figures 1-5 The technical solution shown, based on Embodiment 1, discloses the following to address the inconvenience of continuous detection: a servo motor 6 is installed at the lower end of the fixed column 2, and a self-immersion mechanism is provided at the upper end of the servo motor 6. The self-immersion mechanism includes a threaded rod 7, and the lower end of the threaded rod 7 is connected to the output end of the servo motor 6. The self-immersion mechanism also includes a baffle 8, and the outer side of the baffle 8 is fixedly installed on the inner wall of the fixed column 2. The fixed column 2 is located below the lifting block 3, and the interior of the lifting block 3 is threadedly connected to the surface of the threaded rod 7. A sealing strip 10 is fixedly installed on the upper inner wall of the fixed column 2, and the inner side of the sealing strip 10 is attached to the surface of the lifting block 3.

[0029] When performing a sealing test on the joint components, the handrail bend is prepared and placed on the surface of the placement platform 4. By activating the servo motor 6 at the bottom of the fixed column 2, the servo motor 6 drives the threaded rod 7 to rotate. When the threaded rod 7 rotates, it can drive the lifting block 3 connected to its surface threadedly. Under the limit of the fixed column 2, the lifting block 3 can adjust its height as the threaded rod 7 rotates. During the test, the height of the handrail bend and the connecting parts can be adjusted, and continuous testing can be performed without the need for the staff to put their hands into the device, avoiding the peeling of hands from prolonged immersion in water, and improving the comfort of the staff.

[0030] Example 3: Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution shown, based on Embodiment 2, discloses the following to address the potential slow detection speed: a fixing plate 13 is fixedly installed at the lower end of the housing 1, and a detection facilitating mechanism is installed on the surface of the fixing plate 13. This detection facilitating mechanism includes a second airbag 14, the lower end of which is installed on the surface of the fixing plate 13. The detection facilitating mechanism also includes a first airbag 11, the lower end of which is fixedly installed on the inner wall of the fixing column 2, and the upper end of the first airbag 11 forms a pressing structure with the lifting block 3. The outer surface of the first airbag 11... The side is connected to the air guide hose 12, and the outer side of the air guide hose 12 passes through the fixing plate 13 to connect to the second airbag 14. The fixing plate 13 is L-shaped. The lower end of the housing 1 is fixedly installed with a limit rod 17, and a knocking plate 15 is installed through the surface of the limit rod 17. The inner side of the knocking plate 15 is slidably connected to the fixing plate 13 through the slider 16. The lower end of the knocking plate 15 is correspondingly set with the surface of the second airbag 14. A vibration spring 18 is sleeved on the surface of the limit rod 17, and the upper and lower ends of the vibration spring 18 are installed between the housing 1 and the knocking plate 15.

[0031] When the lifting block 3 lowers the placement platform 4, and the handrail bend and connector components are submerged in water, the lifting block 3 presses the first airbag 11. The first airbag 11 is squeezed and the gas inside is transported through the air guide hose 12 to the second airbag 14 on the fixed plate 13. After receiving the gas, the second airbag 14 expands and pushes the striking plate 15 upward. The striking plate 15 moves upward along the limit rod 17 and the slider 16, so that the striking plate 15 strikes the housing 1. Under the action of the vibration spring 18, the striking effect is improved and the striking efficiency is ensured. The housing 1 is vibrated, achieving the effect of vibration-assisted measurement, improving the efficiency of sealing detection, and quickly detecting whether the connector components of the handrail bend are leaking. It is efficient and convenient.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
