Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, specifically a pressure resistance testing fixture. Background Technology

[0002] A pressure vessel is a sealed container that can withstand pressure. Pressure vessels have a wide range of applications and play an important role in many sectors such as industry, civil use, military industry, and scientific research. Therefore, every pressure vessel needs to undergo a pressure resistance test. In our daily experiments, the mouth of the container is sealed by multiple bolts and flanges, which leads to the need to frequently tighten and loosen the bolts, which is extremely inconvenient.

[0003] Therefore, this solution proposes a pressure testing fixture that does not require bolt installation, effectively improving the convenience and efficiency of pressure testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure testing fixture that solves the problem mentioned in the background art: existing testing fixtures require multiple bolts and flanges to seal the container opening, resulting in cumbersome use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure testing fixture, comprising a tank, a sealing cover, a flange cover, a clamping plate, and a telescopic mechanism. A main body is mounted on the top of the tank. Second threaded rods are mounted on both sides of the main body, threadedly connected to the sides of the main body. An adjusting rod is welded to one end of each second threaded rod, and a clamping plate is mounted on the other end of the second threaded rod. The clamping plate is rotatably connected to the end of the second threaded rod. A first threaded rod is mounted on the top of the main body, threadedly connected to the top of the main body. A turntable is welded to the top of the first threaded rod. A flange cover is fitted onto the bottom end of the first threaded rod, rotatably connected to the bottom of the first threaded rod. Telescopic mechanisms are mounted on both sides of the main body, with the bottom end of each telescopic mechanism connected to the sealing cover. The interior of the main body is connected to the pressure gauge detection end.

[0006] Preferably, the telescopic mechanism includes a base, one end of which is rotatably connected to the middle of a wrench, one end of which is rotatably connected to one end of a connecting rod, the other end of which is rotatably connected to a push rod, the outer wall of which is slidably connected to one end of the base, and the bottom end of which is embedded inside the sealing cover. By rotating the wrenches on both sides of the main body of the device, one end of the wrench can drive the push rod to slide through the connecting rod. While the push rod slides, it can push the sealing cover downward, so that the sealing cover can fit against the surface of the tank.

[0007] Preferably, the inner bottom of the sealing cover has a sloping structure, the outer wall of the sealing cover is in close contact with the outer wall of the device body and slides in contact, and one end of the bottom of the sealing cover is made of rubber. The sloping structure at the bottom of the sealing cover can fit well with the surface of the tank, thereby enabling the sealing cover to maintain a good seal with the tank.

[0008] Preferably, two clamping plates are provided, and the surfaces of the two clamping plates are arc-shaped. The surfaces of the clamping plates are in close contact with the top of the tank. The arc-shaped clamping plates allow their surfaces to fit well with the tank opening, thereby improving the firmness of clamping the tank opening.

[0009] Preferably, the bottom of the flange cover is made of rubber, and the bottom of the flange cover fits tightly against the top of the tank. The rubber material at the bottom of the flange cover enables the flange cover and the tank to maintain a high degree of sealing.

[0010] This utility model provides a pressure resistance testing fixture. It has the following beneficial effects:

[0011] (1) The pressure resistance test fixture, when in use, is fitted onto the mouth of the container by rotating the adjusting rod, which in turn drives the second threaded rod to rotate. The rotation of the second threaded rod pushes the two clamping plates inside the main body of the device to move, thereby clamping the mouth of the container. Then, the turntable is rotated, which drives the first threaded rod to rotate. The first threaded rod drives the flange cover to move downward through the threads on the outer wall, thereby making the flange cover fit tightly against the mouth of the container, so that the mouth of the container can be quickly closed, thereby conducting a pressure resistance test, thus improving the convenience of using the test fixture.

[0012] (2) This pressure resistance test fixture, by rotating the wrenches on both sides of the main body of the device, allows one end of the wrench to slide through the connecting rod to drive the top rod. While the top rod slides, it can push the sealing cover downward, so that the sealing cover can fit against the surface of the tank, thereby making the inside of the main body of the device a sealed space. When the tank opening leaks, the air pressure inside the main body of the device will change, thereby causing the pressure gauge reading to change. By observing the pressure gauge reading, it is possible to intuitively monitor whether there is a leak at the tank opening, thereby improving the functionality of the device.

[0013] This solves the problem that existing experimental fixtures require multiple bolts and flanges to seal the container opening, making them cumbersome to use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example 1:

[0022] Please see Figure 1-5This utility model provides a technical solution: a pressure testing fixture, including a tank 1, a sealing cover 2, a flange cover 8, a clamping plate 9, and a telescopic mechanism 10. A device body 3 is mounted on the top of the tank 1. Second threaded rods 6 are mounted on both sides of the device body 3, threadedly connected to the sides of the device body 3. An adjusting rod 7 is welded to one end of each second threaded rod 6, and a clamping plate 9 is mounted on one end of each second threaded rod 6, rotatably connected to the end of the second threaded rod 6. A first threaded rod 4 is mounted on the top of the device body 3, threadedly connected to the top of the device body 3. A turntable 5 is welded to the top of the first threaded rod 4. A flange cover 8 is fitted onto the bottom end of the first threaded rod 4, rotatably connected to the bottom of the first threaded rod 4. Telescopic mechanisms 10 are mounted on both sides of the device body 3, with one bottom end of the telescopic mechanism 10 connected to the sealing cover 2. Two clamping plates 9 are provided. The two clamping plates 9 have an arc-shaped surface structure, and their surfaces are tightly fitted to the top of the tank 1. The bottom of the flange cover 8 is made of rubber and is also tightly fitted to the top of the tank 1. When using this device, the main body 3 is fitted onto the opening of the container. By rotating the adjusting rod 7, the adjusting rod 7 can drive the second threaded rod 6 to rotate. As the second threaded rod 6 rotates, it can push the two clamping plates 9 inside the main body 3 to move, thereby clamping the opening of the tank 1. Then, the turntable 5 is rotated, which can drive the first threaded rod 4 to rotate. The first threaded rod 4 will drive the flange cover 8 to move downward through the threads on its outer wall, thereby allowing the flange cover 8 to fit tightly against the opening of the tank 1, enabling the opening of the tank 1 to be quickly closed, thus conducting a pressure test and improving the ease of use of this testing fixture.

[0023] Example 2:

[0024] This utility model provides a technical solution: a pressure testing fixture, the telescopic mechanism 10 includes a base 101, one end of the base 101 is rotatably connected to the middle of a wrench 102, one end of the wrench 102 is rotatably connected to one end of a connecting rod 103, the other end of the connecting rod 103 is rotatably connected to a top rod 104, the outer wall of the top rod 104 is slidably connected to one end of the base 101, one bottom end of the top rod 104 is embedded inside a sealing cover 2, the inner bottom side of the sealing cover 2 has a sloped structure, the outer wall of the sealing cover 2 is tightly fitted and slidably contacted with the outer wall of the device body 3, one bottom end of the sealing cover 2 is made of rubber, and the interior of the device body 3 is in contact with the pressure... The detection end of Table 11 is connected. By rotating the wrenches 102 on both sides of the main body 3 of the device, one end of the wrench 102 can drive the top rod 104 to slide through the connecting rod 103. While the top rod 104 slides, it can push the sealing cover 2 downward, so that the sealing cover 2 can fit against the surface of the tank 1, thereby making the inside of the main body 3 of the device a sealed space. When a leak occurs at the opening of the tank 1, the air pressure inside the main body 3 of the device will change, thereby causing the pressure gauge 11 to change. By observing the value of the pressure gauge 11, it is possible to intuitively monitor whether there is a leak at the opening of the tank 1, thereby improving the functionality of the device.

[0025] Working Principle: This device fits its main body onto the container opening and operates the adjusting rod 7 to drive the second threaded rod 6 to rotate. This causes the two clamping plates 9 inside the device to move, clamping the opening of the tank 1. Subsequently, rotating the turntable 5 drives the first threaded rod 4 to rotate, causing the flange cover 8 to move downwards along the outer wall of the tank 1 through the thread action, achieving a tight fit with the opening of the tank 1, quickly sealing the opening and facilitating pressure tests. This improves the ease of use of the tooling. Furthermore, by rotating the wrenches 102 on both sides of the main body 3, one end of the wrench 102 drives the top rod 104 to slide via the connecting rod 103. The top rod 104 pushes the sealing cover 2 to fit against the surface of the tank 1, forming a sealed space. When leakage occurs at the opening of the tank 1, the change in internal air pressure causes a change in the pressure gauge 11 reading. By observing the pressure gauge 11, the leakage can be directly monitored, enhancing the monitoring function of the device.
