Technical Field

[0001] This utility model relates to the field of grooved connector testing technology, specifically to a testing device for grooved connectors in metal products. Background Technology

[0002] Grooved metal connectors are mechanical connection devices widely used in piping systems. Their core principle involves pressing annular grooves onto the pipe ends using specialized grooving equipment, followed by tightening with clamps featuring rubber sealing rings. These connectors mainly consist of three components: grooved pipe fittings, rigid / flexible clamps, and matching sealing rings. They offer advantages such as easy installation, allowance for axial pipe displacement, superior seismic performance, and convenient maintenance. They have significantly replaced traditional welding methods in fire sprinkler systems, building water supply and drainage, and industrial pipelines, and are particularly suitable for connecting metal pipes such as steel and stainless steel pipes, improving construction efficiency by over 50%.

[0003] After the grooved connectors are manufactured, they need to be tested for compressive strength, that is, to observe whether there is deformation or cracking on their surface under a certain pressure. Existing testing equipment does not have the function of safety protection. During the pressure application process, the grooved connectors are prone to sputtering debris in all directions, which can easily cause injury to nearby personnel, resulting in poor safety. Therefore, those skilled in the art provide a testing device for grooved connectors of metal products to solve the problems mentioned in the background art. Utility Model Content

The telescopic end of the hydraulic cylinder 22 extends to the bottom of the stand 21 and is fixedly connected to a connecting column 23. A connecting block 231 is fixedly installed at the bottom of the connecting column 23. A pressure block 232 is detachably connected to the bottom of the connecting block 231. A support member 233 is fixedly installed on the outer wall of the connecting block 231. A connecting frame 234 is detachably connected to the end of the support member 233. A transparent cover 235 is fixedly connected to the bottom of the connecting frame 234. After the grooved connector is fixed, the hydraulic cylinder 22 is controlled to extend, which can drive the connecting... The column 23 moves downward as a whole, and the pressure block 232 applies pressure to the groove connector to achieve the detection function. At the same time, it will also move the transparent cover 235 downward. The transparent cover 235 will cover the groove connector to prevent debris from the groove connector from easily causing injury to nearby personnel, thus increasing the safety of the detection work. The transparent cover 235 is made of transparent acrylic, which allows users to observe the pressure detection status through the transparent cover 235. The pressure block 232 is installed on the connecting block 231 with bolts. Users can replace the damaged pressure block 232. The connecting frame 234 is installed on the support 233 with bolts. Users can replace the damaged transparent cover 235.

[0022] As one implementation method in this embodiment, please refer to Figure 3As shown, the protective testing mechanism 2 also includes a support leg 24, which is fixedly installed on the top of the workbench 1. A pressure seat 25 is fixedly installed on the top of the support leg 24. The top of the pressure seat 25 has multiple through holes 26. The pressure seat 25 is used to support the grooved connector. The design of the through holes 26 facilitates the passage of heated air.

[0023] As one implementation method in this embodiment, please refer to Figure 3 As shown, a protruding seat 27 is fixedly installed on the top of the pressure seat 25. An electric cylinder 271 is fixedly installed on one side of the protruding seat 27. The telescopic end of the electric cylinder 271 extends to the other side of the protruding seat 27 and is detachably connected to multiple clamping blocks 272. After the grooved connector is placed at the center of the top of the pressure seat 25, the electric cylinder 271 is controlled to extend, which can drive the clamping blocks 272 to move toward the grooved connector, thereby realizing the function of clamping and fixing the grooved connector.

[0024] As one implementation method in this embodiment, please refer to Figure 4 As shown, the high-temperature testing mechanism 3 includes a support sleeve 31, which is detachably connected to the top of the workbench 1. A gas channel 32 is fixedly installed on the inner wall of the support sleeve 31. The support sleeve 31 is installed on the top of the workbench 1 by means of bolts, which makes it convenient for users to disassemble and maintain the high-temperature testing mechanism 3 as a whole.

[0025] As one implementation method in this embodiment, please refer to Figure 4 As shown, a duct fan 36 is fixedly connected to one end of the gas channel 32, and a connecting cover 33 is fixedly connected to the other end of the gas channel 32 away from the duct fan 36. An electric heating mesh 34 is fixedly installed on the inner wall of the connecting cover 33, and a stainless steel wire mesh 35 is movably inserted into the inner cavity of the connecting cover 33. When the duct fan 36 is controlled to work, it can absorb air and deliver it into the inner cavity of the gas channel 32. The air then passes through the connecting cover 33 and then through the through hole 26 and is sprayed onto the grooved connector. At this time, the air can be heated by the electric heating mesh 34 to heat the grooved connector, thereby enabling the testing of the compressive strength of the grooved connector under high temperature conditions. The stainless steel wire mesh 35 is used to block debris that may fall into the through hole 26, ensuring the safety of the electric heating mesh 34.

[0026] As one implementation method in this embodiment, please refer to Figure 4As shown, a connector 37 is fixedly connected to the end of the duct fan 36 away from the gas passage 32. A connector 38 is threadedly connected to the end of the connector 37 away from the duct fan 36. An air filter cartridge 39 is fixedly connected to the end of the connector 38. The air filter cartridge 39 is used to filter the air absorbed by the duct fan 36 to ensure the smooth flow of the subsequent pipeline. The connection relationship between the connector 37 and the connector 38 is designed to facilitate the user to disassemble and clean the air filter cartridge 39.

[0027] Working principle: In use, the grooved connector is placed at the center of the top of the pressure seat 25. The electric cylinder 271 is extended, which moves the clamping block 272 toward the grooved connector to clamp and fix it. If it is necessary to test the compressive strength of the grooved connector under high temperature, the pipe fan 36 and the electric heating network 34 are operated for a period of time to heat the grooved connector. Then, the hydraulic cylinder 22 is extended, which moves the connecting column 23 downward. The pressure block 232 applies pressure to the grooved connector to achieve the testing function and observe whether there is deformation or crack on its surface as a basis for judging whether it is qualified. At the same time, the transparent cover 235 will move downward and cover the grooved connector from all sides to achieve the protection function.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
