Description

Technical Field

[0001] This utility model relates to the field of pressure resistance testing technology for metal products, specifically a high-strength loading device for testing the pressure resistance performance of metal products. Background Technology

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar everyday metal products, etc. Some of these pressure vessels, piping systems, heat exchangers, pumps and valves, as well as others such as hydraulic cylinders and compressed air tanks, require certain standard sealing and pressure resistance tests to ensure their strength and sealing performance.

[0003] Upon investigation, Chinese utility model patent with publication number CN215065819U discloses a pressure resistance testing device for 3D printed metal products, including a frame, a liquid storage tank, a booster pump, a conversion plate, a base, a support base, and a connecting pipe.

[0004] This pressure resistance testing device, through its structure design of a base, connecting pipe, and conversion plate working together, can quickly switch between different types and specifications of connectors when testing the sealing or pressure resistance performance of different products, meeting the testing needs of various products. While ensuring stable operation, it improves the applicability and versatility of the device. However, since the device fixes different types and specifications of connectors on the conversion plate, the connector components cannot rotate on their own to tighten the threads between them and the metal product being tested. The metal products to be tested are diverse, and some are limited by their size, weight, or the style of the connecting pipe, preventing them from rotating and tightening themselves. In such cases, the connection between the pressure resistance testing device and the metal product being tested becomes incompatible.

[0005] Therefore, this utility model provides a high-strength loading device for testing the pressure resistance of metal products to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a high-strength loading device for testing the pressure resistance of metal products, aiming to solve the problems mentioned in the background art, such as the inability of the joint element of the existing pressure resistance testing device to rotate and tighten the thread between itself and the metal product to be tested.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a high-strength loading device for testing the pressure resistance of metal products, comprising a frame, a booster pump fixedly mounted on the frame, a storage tank fixedly mounted inside the frame and connected to the input end of the booster pump, a delivery pipe fixedly mounted at the output end of the booster pump, a rotating disk rotatably mounted on the frame, several connectors mounted on the rotating disk, and a connecting mechanism mounted on the end of the delivery pipe away from the booster pump for connecting the connectors. A rotating gear is rotatably connected inside the rotating disk, and several driven gears are arranged in a circular array inside the rotating disk corresponding to the outer periphery of the rotating gear. The connector passes through the rotating disk and the driven gear in sequence. The connector and the driven gear are fixedly connected, and the connector and the rotating disk are rotatably connected. The rotating gear and the driven gear mesh with each other. A rotating shaft is rotatably connected to the frame. The rotating shaft passes through the rotating disk and the rotating gear in sequence. The rotating shaft is rotatably connected to the rotating disk and is fixedly connected to the rotating gear. Threads are provided on the outer walls of both ends of the connector. A working port is provided on the frame at the position where the connector is used. The rotating shaft drives the rotating gear, and the rotating gear drives the driven gear, thereby causing the connector to rotate. This method allows the connector to be connected to the metal product without rotating the metal product.

[0010] Preferably, the rotating disk, rotating shaft, and rotating gear are coaxially arranged, which can ensure that when the rotating shaft drives the rotating gear to rotate, its own position remains unchanged and it is always engaged with the driven gear, driving the driven gear to rotate.

[0011] Preferably, the driven gear and the connector are coaxially arranged, which ensures that the position of the connector remains unchanged when the driven gear rotates and drives the connector to rotate, thereby enabling the connector to be smoothly and stably threadedly connected to the metal product.

[0012] Preferably, an axially penetrating sleeve is fixedly installed inside the rotating disk at a position between adjacent joints, and a pin is slidably inserted into the rotating disk at the position of the sleeve.

The inner wall of the externally threaded pipe is provided with threads, and the threads on the externally threaded pipe match the threads on the connector. The outer wall of the rigid pipe fits against the inner wall of the connector. During the threaded connection between the externally threaded pipe and the connector, the inner rubber ring and the outer rubber ring will contact and be fully compressed to enhance the sealing performance.

[0014] Preferably, the frame is fixedly provided with a fixing member for fixing the position and height of the rigid tube. The fixing member is movably sleeved on the rigid tube. The fixing member can keep the connecting mechanism at the same height as the joint during the connection process between the connecting mechanism and the joint, so as to ensure the stability of the connection.

[0015] (III) Beneficial Effects

[0016] This utility model uses a rotating disk. Rotating the rotating disk causes the connector and its driven gear to rotate around the rotating gear. The connector and its corresponding driven gear, which are compatible with the metal product to be tested, are rotated to the working port position on the frame. The connector of the metal product to be tested is placed close to the working port position, the rotating disk is fixed, and then the rotating shaft is rotated. The rotating shaft drives the rotating gear to rotate, and the rotating gear drives the driven gear meshing with it to rotate, thereby driving the connector to rotate. The connector and the metal product are connected without rotating the metal product.

[0017] This utility model incorporates a rigid tube that will not deform, ensuring a tight fit between the test rigid tube and the inner wall of the connector, thus enhancing the sealing performance. During the threaded connection between the external threaded tube and the connector, the inner and outer rubber rings come into contact and are fully compressed, further enhancing the sealing performance.

Detailed Implementation

[0024] 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.

[0025] This utility model provides a high-strength loading device for testing the compressive strength of metal products, referring to... Figures 1 to 2 The system includes a frame 1, a booster pump 2 fixedly mounted on the frame 1, a storage tank 3 fixedly mounted inside the frame 1 and connected to the input end of the booster pump 2, a delivery pipe 21 fixedly mounted at the output end of the booster pump 2, a rotating disk 4 rotatably mounted on the frame 1, several connectors 5 mounted on the rotating disk 4, and a connecting mechanism 23 located at the end of the delivery pipe 21 away from the booster pump 2 for connecting the connectors 5. A rotating gear 41 is rotatably connected inside the rotating disk 4, and several components are arranged in a circular array corresponding to the outer periphery of the rotating gear 41 inside the rotating disk 4. The driven gear 42 and the connector 5 pass through the rotating disk 4 and the driven gear 42 in sequence. The connector 5 and the driven gear 42 are fixedly connected. The connector 5 and the rotating disk 4 are rotatably connected. The rotating gear 41 and the driven gear 42 mesh with each other. A rotating shaft 43 is rotatably connected to the frame 1. The rotating shaft 43 passes through the rotating disk 4 and the rotating gear 41 in sequence. The rotating shaft 43 is rotatably connected to the rotating disk 4. The rotating shaft 43 and the rotating gear 41 are fixedly connected. The outer walls of both ends of the connector 5 are provided with threads. A working port 12 is opened on the frame 1 at the position corresponding to the use of the connector 5.

[0026] During the pressure resistance test of the metal product, the rotating disk 4 is rotated, causing the connector 5 and the driven gear 42 to rotate around the rotating gear 41. The connector 5 and the corresponding driven gear 42, which are compatible with the metal product to be tested, are rotated to the working port 12 position on the frame 1. The metal product to be tested is placed near the connector 5 at the working port 12 position, and the rotating disk 4 is fixed. Then, the rotating shaft 43 is rotated, causing the rotating gear 41 to rotate. The rotating gear 41 drives the driven gear 42 meshing with it to rotate, and the driven gear 42 drives the connector 5 to rotate. The connector 5 is threaded onto the metal product to be tested. The connection is made by connecting the other end of the delivery pipe 21 to the connector 5 via the connection mechanism 23. The test liquid is delivered to the booster pump 2 via the storage tank 3. After being pressurized by the booster pump 2, the test liquid is delivered to the connector 5 via the delivery pipe 21. The test liquid is delivered into the metal product from the connector 5. The pressure of the test liquid in the metal product is controlled by the booster pump 2 to test the pressure resistance of the metal product. The rotating shaft 43 drives the rotating gear 41, and the rotating gear 41 drives the driven gear 42, thereby driving the connector 5 to rotate. This method can connect the connector 5 and the metal product without rotating the metal product.

[0027] Furthermore, refer to Figures 1 to 2 The rotating disk 4, rotating shaft 43 and rotating gear 41 are coaxially arranged, which can ensure that when the rotating shaft 43 drives the rotating gear 41 to rotate, its own position remains unchanged and it always meshes with the driven gear 42, driving the driven gear 42 to rotate.

[0028] Furthermore, refer to Figures 1 to 2 The driven gear 42 and the connector 5 are coaxially arranged, which ensures that when the driven gear 42 rotates and drives the connector 5 to rotate, the position of the connector 5 remains unchanged, thereby enabling the connector 5 to be smoothly and stably connected to the threaded metal product.

[0029] It is worth noting that, referring to Figures 2 to 3 An axially penetrating sleeve 44 is fixedly installed inside the rotating disk 4 at a position between adjacent joints 5. A pin 45 is slidably inserted into the rotating disk 4 at the position of the sleeve 44. A slot 11 matching the pin 45 is provided on the frame 1. After the joint 5 that is compatible with the metal product is rotated to a suitable position within the working port 12, the pin 45 is moved axially. The pin 45 slides inside the sleeve 44 and is inserted into the slot 11 on the frame 1, which can stably fix the position of the rotating disk 4, thereby fixing the position of the joint 5.

[0030] It should be noted that, referring to Figures 4 to 5 The connecting mechanism 23 includes a rigid pipe 231 fixedly installed at the end of the conveying pipeline 21 away from the booster pump 2, an externally threaded pipe 232 rotatably connected to the rigid pipe 231, an inner rubber ring 233 fixedly installed on the inner wall of the externally threaded pipe 232 and in contact with the rigid pipe 231, and an outer rubber ring 234 fixedly installed at the end of the connector 5 near the rigid pipe 231 and in contact with the inner rubber ring 233. The inner wall of the externally threaded pipe 232 is threaded, and the thread on the externally threaded pipe 232 matches the thread on the connector 5. The outer wall of the rigid pipe 231 fits against the inner wall of the connector 5, and the rigid pipe 231 will not deform, which can ensure that the test rigid pipe 231 and the inner wall of the connector 5 are always tightly fitted, enhancing the sealing performance. During each test, the connecting mechanism 23 needs to be connected to one of the connectors 5, which will cause more severe wear on the connecting mechanism 23. Therefore, sufficient sealing is required. During the threaded connection between the externally threaded pipe 232 and the connector 5, the inner rubber ring 233 and the outer rubber ring 234 will contact and fully compress, enhancing the sealing performance.

[0031] Furthermore, refer to Figure 1 , Figure 4 The frame 1 is fixedly provided with a fixing member 22 for fixing the position and height of the rigid tube 231. The fixing member 22 is movably sleeved on the rigid tube 231. The fixing member 22 can keep the connecting mechanism 23 at the same height as the connector 5 during the connection process between the connecting mechanism 23 and the connector 5, so as to ensure the stability of the connection.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
