[0002] High-pressure oxygen tank testing is an important test for high-pressure oxygen tanks to ensure their safety and reliability during use. This test mainly simulates the pressure conditions that high-pressure oxygen tanks may encounter in actual working environments, and checks their structural integrity, sealing performance, and ability to withstand pressure by inputting gas into the tank.

[0003] In the existing high-pressure oxygen tank pressure test process, the quick-connect operation is particularly cumbersome, which not only increases the time cost of the test, but also may lead to safety hazards caused by improper operation during the docking process. At the same time, the high-pressure oxygen tank test equipment on the market generally lacks the function of effectively fixing the tank body. During the pressure test, the tank body may shake or move due to pressure changes, which will not only affect the accuracy of the test results, but also pose a threat to the equipment and operators, greatly reducing the safety and reliability of the test. Therefore, we propose a high-pressure oxygen tank quick-connect test device. Utility Model Content

[0015] See also Figure 1-5 The utility model provides a technical solution: a high-pressure oxygen tank quick-connect test device, including a base 1, a bottom plate 2 is arranged on one side of the upper end of the base 1, side plates 3 are arranged on both sides of the bottom plate 2, top plates 4 are fixedly installed on the tops of the two side plates 3, joints 5 are fixedly installed on both sides of the bottom of the top plate 4, mounting grooves are opened on the top of the base 1 corresponding to both sides of the lower end of the bottom plate 2, electric push rods 6 are fixedly installed inside the two mounting grooves, placement grooves 7 are opened on both sides of the top of the bottom plate 2, and clamps 15 are arranged on both sides of the placement groove 7. A transmission groove 8 is provided at the lower ends of the two placement grooves 7 respectively corresponding to the inside of the base 1, and a bidirectional screw 9 is provided at the top of the transmission groove 8. Threaded plates 10 are threadedly connected to both sides of the surface of the bidirectional screw 9, and a driven gear 11 is fixedly installed at the center position of the surface of the bidirectional screw 9. The front end of the driven gear 11 is meshedly connected with a driving gear 12. Rotating rods 13 are movably installed on both sides of the front surface of the bottom plate 2, and a handle 14 is fixedly installed at the front end of the rotating rod 13. A test device body 16 is fixedly installed on the other side of the top of the base 1.

[0016] A rubber sealing pad is provided inside the joint 5, and the test device body 16 is connected to the two joints 5 through a conduit to ensure a tight connection between the high-pressure oxygen tank and the test device to prevent gas leakage, thereby ensuring the safety and accuracy of the test process.

[0017] Slide blocks are fixedly connected to the centers of both sides of the base plate 2, and slide grooves are provided at the bottom positions on the opposite sides of the two side plates 3. The opposite ends of the two slide blocks extend to the interior of the two slide grooves and are slidably connected to the inner walls of the slide grooves, ensuring that the base plate 2 can be lifted and lowered smoothly under the drive of the electric push rod 6, preventing shaking or deviation during the test, and ensuring the stability of the test.

[0018] The electric push rod 6 is fixedly connected to a driving rod through the output end at its top. The upper ends of the two driving rods respectively penetrate the outside of the two mounting grooves and are respectively fixedly connected to the two sides of the bottom of the base plate 2, providing lifting power so that the base plate 2 and the high-pressure oxygen tank thereon can move up and down, which is convenient for quick connection with the connector 5.

[0019] The two clamps 15 are both arranged in an arc-shaped structure, and the two clamps 15 are arranged symmetrically on the left and right, ensuring that the clamps 15 can closely fit the surface of the high-pressure oxygen tank, provide a uniform and stable clamping force, and prevent the high-pressure oxygen tank from shaking or falling off during the test.

[0020] The two ends of the bidirectional screw 9 are movably connected to the bearings fixedly installed on the top of the inner wall of the transmission groove 8 on both sides. Horizontal grooves are opened on both sides of the bottom of the placement groove 7. The upper ends of the two threaded plates 10 respectively penetrate the outside of the two horizontal grooves and are fixedly connected to the bottom of the two clamping plates 15 respectively. A guide rod 17 is provided at the bottom of the transmission groove 8. The two ends of the guide rod 17 respectively penetrate the outside of the two threaded plates 10 and are fixedly connected to the inner wall of the transmission groove 8 to ensure that the threaded plate 10 can only move along the direction of the guide rod 17 under the transmission of the bidirectional screw 9 to prevent displacement or distortion.

[0021] The rear ends of the two rotating rods 13 penetrate into the interior of the base plate 2 and are fixedly connected to the center of the front surfaces of the two driving gears 12 respectively. The function of the rotating rods 13 and the driving gears 12 connected thereto is to provide manual driving force. The opening and closing action of the clamping plate 15 can be achieved by rotating the rotating rods 13, which is convenient for the operator to perform clamping and releasing operations.

[0022] Working principle: First, place the high-pressure oxygen tank to be tested in the placement groove 7 on the base plate 2. At this time, the operator turns the handle 14 to drive the rotating rod 13 and the driving gear 12 fixedly connected thereto to rotate. Since the driving gear 12 is meshed with the driven gear 11, the driven gear 11 rotates accordingly, thereby driving the bidirectional screw 9 to rotate in the bearing in the transmission groove 8. The rotation of the bidirectional screw 9 causes the two threaded plates 10 to move toward each other under the guidance of the guide rod 17, thereby pushing the two arc-shaped clamping plates 15 to move closer to the high-pressure oxygen tank until they are tightly fitted and firmly clamped to ensure that they will not shake or fall off during the test. When the high-pressure oxygen tank is fixed, the electric push rod 6 starts to work. The output end at the top of the electric push rod 6 drives the base plate 2 and the high-pressure oxygen tank on it to rise steadily along the slide groove on the side plate 3 through the driving rod. Since the centers of both sides of the base plate 2 are fixedly connected with sliders and slide with the inner wall of the slide groove The bottom plate 2 is connected, so the lifting process of the bottom plate 2 is stable and reliable. When the bottom plate 2 rises to a certain height, so that the bottle mouth of the high-pressure oxygen tank enters the joint 5 and contacts the rubber sealing pad, the electric push rod 6 stops working, and the test device body 16 is connected to the two joints 5 through a conduit to form a complete test system. Subsequently, the test device body 16 starts to work and inputs gas into the high-pressure oxygen tank to perform a pressure test. During the test, the test device body 16 monitors and records the pressure changes and various performance indicators of the high-pressure oxygen tank in real time to ensure the accuracy and safety of the test. When the test is completed, the electric push rod 6 works again to drive the bottom plate 2 to descend, so that the high-pressure oxygen tank is separated from the joint 5. At the same time, the operator rotates the handle 14 in the opposite direction to move the two clamps 15 in opposite directions to release the clamping force on the high-pressure oxygen tank. Finally, the operator can take the high-pressure oxygen tank out of the placement slot 7 to complete the entire test process.

[0023] In summary, the high-pressure oxygen tank quick-connect test device, through the design of the placement slot 7, the bidirectional screw 9, the threaded plate 10, the driven gear 11, the driving gear 12, the rotating rod 13, the handle 14 and the clamping plate 15, the operator only needs to turn the handle 14, and the meshing transmission of the driving gear 12 and the driven gear 11 can drive the bidirectional screw 9 to rotate, thereby driving the two threaded plates 10 to move toward or away from each other under the guidance of the guide rod 17, thereby adjusting the position of the clamping plate 15, and realizing the rapid clamping and precise positioning of the high-pressure oxygen tank. It is not only easy to operate, but also has a uniform and stable clamping force, which can effectively prevent the high-pressure oxygen tank from shaking or displacement during the test, and ensure the accuracy and safety of the test results. The design of the bottom plate 2, the side plate 3, the top plate 4, the joint 5 and the electric push rod 6 can quickly complete the test preparation work by controlling the two electric push rods 6 to push the high-pressure oxygen tank fixed on the bottom plate 2 to move upward, and make the joint 5 dock with it, thereby improving the test efficiency and meeting the market demand.
