Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pipeline sealing testing equipment, specifically a pipeline sealing tester. Background Technology
[0002] With the continuous development and improvement of bathroom facilities, the importance of bathroom wall handrails has become increasingly prominent. They provide necessary support and safety for users' activities in the bathroom. As a key component connecting the various parts of the handrail, the handrail bend has some significant problems in the use of existing pipe sealing detection devices.
[0003] Bathroom environments are characterized by high humidity and large temperature fluctuations, which places higher demands on the sealing performance of handrail pipes. However, existing testing equipment is insufficient in simulating these actual usage conditions and cannot effectively detect sealing problems that may occur in complex environments. As market expectations for bathroom handrail quality continue to rise, many pipes with potential sealing problems are mistakenly judged as qualified, seriously affecting the overall quality of the product. Due to the limitations of testing technology, the testing process is usually time-consuming, which greatly slows down the production progress and reduces production efficiency in large-scale production scenarios.
[0004] For example, in the pipeline sealing testing device with announcement number CN219956806U, slide blocks are slidably installed on the inner walls of the front and rear ends of the testing chamber via connecting components. Bolts are threaded onto the inner side of the front end of the bottom of the rear slide block, allowing the device to be moved out of the testing chamber under the limiting action of the sliding groove and the slider during use. However, this pipeline sealing testing device has limitations in testing technology, is time-consuming, reduces production efficiency, is complex to operate, and is prone to errors. Furthermore, it has other problems, such as pipeline fixing. Past fixing methods have many unstable factors; the clamping force of the fixing device is not uniform, causing the pipeline to loosen locally during testing, thus affecting the accuracy of the test. The fixing device lacks flexibility and cannot adapt to pipelines of different diameters and shapes, resulting in significant limitations in practical applications. Due to poor fixing, the pipeline may shift during testing due to changes in internal pressure, which not only disrupts the stability of the testing environment but may also cause irreversible damage to the testing equipment and the pipeline itself, increasing maintenance and repair costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe sealing tester, comprising a base and a placement groove formed in the middle of the upper end of the base; a spiral rod is rotatably installed inside the placement groove, with the right end of the spiral rod penetrating through the right end of the base, and a rotating handle is fixedly installed at the right end of the spiral rod; a left fixed clamping plate is rotatably installed at the left end of the spiral rod, and the lower end of the left fixed clamping plate is installed inside the placement groove; a sealing test mechanism is provided at the upper end of the base, and an air pump is fixedly installed on the upper left side of the base, and the air pump is located to the left of the left fixed clamping plate; a fixed outer shell is fixedly installed in the middle of the upper end of the base, and two fixed outer shells are evenly distributed around the placement groove as the symmetrical center; a pipe fixing mechanism is provided at the upper end of the base, and a push switch is movably installed at the front end inside the fixed outer shell, and the push switch is "C" shaped.
[0007] Furthermore, the sealing test mechanism includes a connecting hose that is installed through the upper end of the air pump, and the right end of the connecting hose is installed through the middle of the left fixed clamping plate. A test pipe is provided on the right end of the left fixed clamping plate, and a first sealing ring is provided on the inner side of the right end of the left fixed clamping plate.
[0008] Furthermore, the outer side of the first sealing ring is disposed on the left end of the inner side of the test pipe, the right end of the spiral rod is rotatably mounted with a right fixed clamping plate, and the lower end of the right fixed clamping plate is installed inside the placement groove, and the right end of the test pipe is disposed on the left end of the right fixed clamping plate.
[0009] Furthermore, a pressure detector is installed through the right end of the right fixed clamping plate, and a second sealing ring is provided on the inner side of the left end of the right fixed clamping plate, with the outer side of the second sealing ring located on the right end of the inner side of the test pipe.
[0010] Furthermore, the fixed pipe mechanism includes a first spring installed on the right end of the push switch, and the right end of the first spring is installed inside the right end of the fixed housing, and two first springs are distributed symmetrically around the test pipe.
[0011] Furthermore, a drive eccentric plate is rotatably mounted on the inner side of the right end of the push switch, and two drive eccentric plates are distributed symmetrically around the test pipe. The drive eccentric plate is rotatably mounted inside the fixed housing, and a fixed clamping plate is rotatably mounted on the upper end of the drive eccentric plate.
[0012] Furthermore, the fixing plate is movably installed inside the right end of the fixing housing, and a second spring is installed on the left end of the fixing plate. The left end of the second spring is installed inside the left end of the push switch. A gasket is pasted on the right end of the fixing plate, and the gasket is in contact with the outside of the test pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The screw rod drives the left and right fixed clamping plates to move inward, so that the left and right fixed clamping plates seal both sides of the test pipe. The front end of the air pump on the upper left side of the base inflates the test pipe with air through the connecting hose. Then, the air pressure detector checks the sealing of the test pipe. It can accurately detect extremely small leaks. Whether it is a tiny crack or a tiny pore, it can be accurately identified, which improves the quality and reliability of the product.
[0015] Furthermore, accurate test results reduce the number of product reworks and equipment repairs caused by poor sealing, saving a significant amount of human, material, and financial resources. They also lower the skill requirements for operators, allowing ordinary workers to operate the equipment with simple training, thus reducing test errors caused by human error.
[0016] Furthermore, it provides rigorous testing guarantees, ensuring stable performance of the product under various complex operating environments. The efficient testing process enables the testing of more pipelines per unit time, reducing subsequent maintenance and replacement costs caused by pipeline sealing problems. It can provide test data accurate to minute values, providing a strong basis for refined control and improvement of product quality.
[0017] 2. When the user presses the push switch installed at the front of the fixed housing, the fixed housing squeezes the first spring at both ends, and the push switch squeezes the second spring in the middle. The push switch drives the eccentric plates on both ends to rotate. After the user releases the push switch, the second spring pushes the fixed plate, which fixes the test pipe in place, preventing any possible displacement or loosening, thus ensuring the accuracy and reliability of the test data.
[0018] Furthermore, it can effectively resist changes in internal pipeline pressure and external interference factors during the testing process, ensuring that the pipeline is always in the correct testing position, improving the accuracy and repeatability of the test, avoiding direct collision and friction between the pipeline and the testing equipment, reducing the risk of equipment damage and pipeline damage, effectively preventing pipeline damage, avoiding any damage to the pipeline surface and structure during fixing and testing, and improving the efficiency of the testing work.

The right end of the left fixed clamping plate 5 is provided with a test pipe 11. The inner side of the right end of the left fixed clamping plate 5 is provided with a first sealing ring 10. The outer side of the first sealing ring 10 is provided at the left end of the inner side of the test pipe 11. The right end of the spiral rod 3 is rotatably installed with a right fixed clamping plate 12, and the lower end of the right fixed clamping plate 12 is installed inside the placement groove 2.
