Technical Field
[0001] This utility model relates to the field of oxygen compressor technology, and more specifically, to a vibration damping device for a piston-type oxygen compressor. Background Technology
[0002] In external compressed air systems, oxygen compressors are used to pressurize low-pressure oxygen to medium- or high-pressure levels before supplying it to users. Piston-type oxygen compressors are commonly used for this pressurization process.
[0003] However, in the use of existing technology, the piston oxygen compressor has a large vibration. The large vibration of the exhaust pipe leads to inaccurate temperature detection, which cannot provide accurate and reliable temperature data for subsequent stable control of exhaust pressure. In addition, it causes the device to be unstable in its fixed position and is prone to slippage, which affects the normal operation of the device. Therefore, a vibration damping device for piston oxygen compressor is proposed. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the large vibration of the piston oxygen compressor leads to inaccurate temperature detection, which in turn makes it impossible to provide accurate and reliable temperature data for subsequent stable control of exhaust pressure. Furthermore, it causes the device to be unstable in its fixed position, making it prone to slippage and affecting the normal operation of the device.
[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a vibration damping device for a piston-type oxygen compressor, comprising a device body. Two second fixing blocks are fixedly connected to the lower surface of the device body. A bidirectional threaded rod is rotatably connected inside the two second fixing blocks. A rotating disk is fixedly connected to one end of the bidirectional threaded rod. Two sliders are threadedly connected to the outer surfaces of both ends of the bidirectional threaded rod, and the threads inside the sliders are adapted to the threads on the outer surfaces of both ends of the bidirectional threaded rod. A connecting rod is rotatably connected inside the sliders. A first fixing block is rotatably connected to the end of the connecting rod away from the slider. A support plate is fixedly connected to the lower surface of the first fixing block. Wheels are provided on the lower surface of the device body.
[0006] As a preferred technical solution of this application, a support base is fixedly connected to the upper surface of the device body, a limit box is fixedly connected to the upper surface of the support base, and a rubber block is provided inside the limit box.
[0007] As a preferred technical solution of this application, an air tube is fixedly connected to the upper surface of the device body, and the outer surface of the air tube is fixedly connected to the inside of the rubber block.
[0008] As a preferred technical solution of this application, the inner wall of the limiting box is fixedly connected with a plurality of dampers arranged in a linear manner, and the end of each damper away from the limiting box is fixedly connected with a limiting plate, and one side of the limiting plate is in contact with the surface of the rubber block.
[0009] As a preferred technical solution of this application, a second spring is sleeved on the outer surface of each damper, and the two ends of the second spring are fixedly connected to the inner wall of the limiting box and one side of the limiting plate, respectively.
[0010] As a preferred technical solution of this application, the upper surface of the support base is provided with a slot, the upper surface of the support base is provided with a protective frame, the lower surface of the protective frame is fixedly connected with a block, and the outer surface of the block is in contact with the inner wall of the slot.
[0011] As a preferred technical solution of this application, the support base has a sliding groove inside, and two limiting posts are slidably connected inside the sliding groove. The outer surfaces of the two limiting posts are fixedly connected to limiting blocks.
[0012] As a preferred technical solution of this application, a first spring is fixedly connected to the near ends of the two limiting posts, and a limiting groove is formed on the side of the support seat near the first spring.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. In the solution of this application: during use, by rotating the rotating disk, the bidirectional threaded rod is driven to rotate, so that the bidirectional threaded rod and the two sliders are threadedly driven. The two sliders move to the middle position, so that the connecting rod, which was originally in a horizontal state, gradually becomes a vertical state. At this time, the support plate slowly moves downward until the support plate is in close contact with the ground, which makes the support of the device more stable and prevents the device from slipping due to vibration during operation, thus affecting the normal use of the device.
[0015] 2. In the solution of this application: during use, by moving the limiting block towards the middle position of the support base, the limiting block drives the limiting post to slide inside the slide groove and compresses the first spring. When the limiting block moves to the position of the limiting groove, the limiting block is pressed down to limit the limiting block inside the limiting groove. Then, the card slot below the protective frame is inserted into the card slot from the front to limit the card block and the protective frame. After the card block is fully inserted into the card slot, the limiting block is moved upward to move the limiting block out of the limiting groove. The first spring returns to its original position and pushes the limiting post to move towards one end of the support base and insert it into the card block to limit and fix the card block and the protective frame. This allows for quick installation and disassembly of the protective frame and protects the internal components from damage caused by external impacts. Attached Figure Description

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A vibration damping device for a piston-type oxygen compressor includes a device body 1. Two second fixing blocks 8 are fixedly connected to the lower surface of the device body 1. A bidirectional threaded rod 9 is rotatably connected inside the two second fixing blocks 8, serving to limit the position of the bidirectional threaded rod 9. A rotating disk 10 is fixedly connected to one end of the bidirectional threaded rod 9, driving the bidirectional threaded rod 9 to rotate. Two sliders 7 are threadedly connected to the outer surfaces of both ends of the bidirectional threaded rod 9, with the internal threads of the sliders 7 matching the threads on the outer surfaces of both ends of the bidirectional threaded rod 9. A connecting rod 6 is rotatably connected inside the sliders 7, driving the connecting rod 6 to move. A first fixing block 5 is rotatably connected to the end of the connecting rod 6 away from the slider 7. A support plate 4 is fixedly connected to the lower surface of the first fixing block 5, with a rubber anti-slip pad on the lower surface of the support plate 4, supporting the device and making it more stable during operation. Wheels 3 are provided on the lower surface of the device body 1, enabling the device to move.
[0028] Furthermore, such as Figure 2 , Figure 4 As shown, a support base 2 is fixedly connected to the upper surface of the device body 1. The support base 2 serves to support subsequent components. A limit box 21 is fixedly connected to the upper surface of the support base 2. A rubber block 20 is provided inside the limit box 21. The rubber block 20 serves to wrap the air tube 19 and reduce the vibration of the air tube 19.
[0029] Furthermore, such as Figure 2 , Figure 4 As shown, an air tube 19 is fixedly connected to the upper surface of the device body 1, and the outer surface of the air tube 19 is fixedly connected to the inside of the rubber block 20.
[0030] Furthermore, such as Figure 4 As shown, multiple dampers 24 arranged linearly are fixedly connected to the inner wall of the limiting box 21. Each damper 24 is fixedly connected to a limiting plate 22 at the end away from the limiting box 21. One side of the limiting plate 22 is in contact with the surface of the rubber block 20. The limiting plate 22 is used to limit the position of the rubber block 20.
[0031] Furthermore, such as Figure 4As shown, a second spring 23 is fitted on the outer surface of each damper 24. The two ends of the second spring 23 are fixedly connected to the inner wall of the limiting box 21 and one side of the limiting plate 22, respectively. The second spring 23 and the damper 24 work together to reduce the vibration of the air pipe 19.
[0032] Furthermore, such as Figure 1 , Figure 3 As shown, a slot 13 is provided on the upper surface of the support base 2, and a protective frame 11 is provided on the upper surface of the support base 2. The protective frame 11 is used to protect the internal device. A locking block 12 is fixedly connected to the lower surface of the protective frame 11. The outer surface of the locking block 12 is in contact with the inner wall of the slot 13. The slot 13 is used to limit the position of the locking block 12.
[0033] Furthermore, such as Figure 1 , Figure 3 As shown, the support base 2 has a sliding groove 14 inside, and two limiting posts 18 are slidably connected inside the sliding groove 14. The outer surfaces of the two limiting posts 18 are fixedly connected to limiting blocks 16, and the limiting posts 18 are used to limit the position of the locking block 12.
[0034] Furthermore, such as Figure 1 , Figure 3 As shown, the two limiting posts 18 are fixedly connected to the near ends of each other with a first spring 15. The support base 2 has a limiting groove 17 on the side near the first spring 15. The first spring 15 is used to push the limiting posts 18 to both sides.
[0035] The operation of the piston-type oxygen compressor vibration damping device provided by this utility model is as follows: During use, the limiting block 16 is moved towards the middle position of the support base 2, causing the limiting block 16 to slide the limiting post 18 inside the slide groove 14 and compress the first spring 15. When the limiting block 16 moves to the position of the limiting groove 17, the limiting block 16 is pressed down to limit it inside the limiting groove 17. Then, the slot 13 below the protective frame 11 is inserted into the slot 13 from the front, using the slot 13 to limit the locking block 12 and the protective frame 11. After the locking block 12 is fully inside the slot 13, the limiting block 16 is moved upward to move it out of the limiting groove 17. The first spring 15 returns to its original position, pushing the limiting post 18 towards one end of the support base 2 and inserting it into the locking block 12, thus limiting and fixing the locking block 12 and the protective frame 11. 1. The protective frame 11 protects the internal components from damage caused by external impacts. Then, the wheels 3 are used to move the device to the desired location. The rotating disk 10 is rotated, which drives the bidirectional threaded rod 9 to rotate, causing the bidirectional threaded rod 9 to engage in threaded transmission with the two sliders 7. The two sliders 7 move towards the center, gradually turning the connecting rod 6, which was originally horizontal, into a vertical position. At this time, the support plate 4 slowly moves downward until it is in close contact with the ground, making the device more stable and preventing it from slipping due to vibration during operation, which would affect the normal use of the device. At the same time, the rubber block 20, the second spring 23, and the damper 24 are used to limit and fix the air pipe 19 to reduce the vibration that the air pipe 19 may generate during use, preventing inaccurate temperature detection due to the vibration of the air pipe 19.
