Description

Technical Field

[0001] This utility model relates to the field of gas spring technology, and in particular to a gas spring inner tube surface cleaning device. Background Technology

[0002] The inner tube of a gas spring refers to the pressure tube, which is usually made of high-strength steel or aluminum alloy. As the outer shell of the gas spring, it bears the internal pressure of the gas spring and the influence of the external environment, protecting the internal mechanism from damage. During the production process, burrs and stains may adhere to the inner surface of the inner tube, requiring cleaning equipment for cleaning.

[0003] In existing technologies, cleaning devices use brushes that extend into the inner tube and rotate to clean its inner surface. However, the brush holder is designed for specific inner tube sizes. When faced with gas spring inner tubes of different sizes, existing cleaning devices may not be able to effectively adjust or adapt, resulting in a significant reduction in cleaning effectiveness or even failure to complete the cleaning task. This necessitates frequent replacement of brushes of different sizes to meet the cleaning requirements. Specifically, if the size of the brush holder does not match the gas spring inner tube, the cleaning brush may not be able to fully contact the inner surface of the tube, leaving cleaning dead zones and resulting in incomplete cleaning and poor cleaning effect. Therefore, an improved gas spring inner tube surface cleaning device is needed to solve the above problems. Utility Model Content

[0004] To overcome the problem that the size of the brush fixing rod of the cleaning device does not match the inner tube of the gas spring, thus leaving cleaning dead corners and resulting in incomplete cleaning.

[0005] The technical solution of this utility model is as follows: a gas spring inner tube surface cleaning device, including a mounting plate, a connecting plate and a mounting mechanism. The mounting plate is provided with a mounting mechanism to fix the position of the mounting plate. An electric telescopic rod is fixedly connected to the top of the mounting plate. A connecting plate is fixedly connected to the top of the electric telescopic rod. A rotating block is rotatably connected inside the connecting plate. A slider is slidably connected inside the rotating block. A mounting rod is fixedly connected to the bottom of the slider. A brush is snapped into the inside of the mounting rod. The slider slides to adjust the position of the brush.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 6 This utility model provides an embodiment of a gas spring inner tube surface cleaning device, including a mounting plate 1, a connecting plate 21, and a mounting mechanism. The mounting plate 1 has a mounting mechanism inside to fix its position. An electric telescopic rod 4 is fixedly connected to the top of the mounting plate 1, and the connecting plate 21 is fixedly connected to the top of the electric telescopic rod 4. A rotating block 23 is rotatably connected inside the connecting plate 21, and a slider 25 is slidably connected inside the rotating block 23. A mounting rod 26 is fixedly connected to the bottom of the slider 25, and a brush 27 is engaged inside the mounting rod 26. The slider 25 slides to adjust the position of the brush 27. The slider 25 slides within the groove of the rotating block 23, driving the mounting rod 26. The mounting rod 26 then adjusts the brush 27 to a position suitable for the inner tube size. The rotating block 23 drives the mounting rod 26 via the slider 25, and the mounting rod 26 drives the brush 27. The brush 27 rotates to clean the inner surface of the inner tube. The height of the brush 27 can be adjusted by raising and lowering the electric telescopic rod 4. The mounting mechanism allows the mounting plate 1 to be installed in a suitable position.

[0022] Please see Figure 1 - Figure 4In this embodiment, the rotating block 23 has a matching groove at the corresponding position of the slider 25, and the slider 25 slides inside the matching groove. The groove limits the slider 25, ensuring that it can only slide inside the groove, making the sliding smoother and preventing deviation. The mounting rod 26 has a matching slot at the corresponding position of the brush 27, and the brush 27 is engaged inside the slot. The slot provides initial positioning of the brush 27, and then the first bolt 28 is used to fix the position of the brush 27, facilitating the replacement of the brush 27 and ensuring its normal operation. The top of the connecting plate 21 is fixedly connected to the drive motor 22, and the rotating block 23 is fixedly connected to the output end of the drive motor 22. The inside of the rotating block 23 is fixedly connected to the limit rod 24, and the slider 25 is slidably connected to the outside of the limit rod 24. The inside of the mounting rod 26 is threaded with... The first bolt 28 is engaged inside the brush 27. A threaded cylinder 29 is fixedly connected to the front of the rotating block 23. A first threaded rod 210 is threadedly connected inside the threaded cylinder 29. A hinge seat 211 is rotatably connected to the bottom of the first threaded rod 210. The hinge seat 211 is slidably connected inside the rotating block 23. A connecting rod 212 is rotatably connected between the hinge seat 211 and the slider 25. The position of the two brushes 27 can be adjusted by rotating the first threaded rod 210, so that the two brushes 27 can be adjusted synchronously to adapt to inner tubes of different sizes. The rotating block 23 has a matching groove at the corresponding position of the hinge seat 211, and the hinge seat 211 slides inside the groove. The groove guides and positions the hinge seat 211 to prevent it from rotating. The first threaded rod 210 can be rotated to push the hinge seat 211 to slide.

[0023] Please see Figure 1 , Figure 5 - Figure 6 In this embodiment, the installation mechanism includes a sliding frame 31, which is slidably connected to the inside of the mounting plate 1. A second threaded rod 32 is rotatably connected inside the sliding frame 31, and a clamping plate 33 is threadedly connected to the outside of the second threaded rod 32. The clamping plate 33 is slidably connected to the inside of the sliding frame 31, and a second bolt 34 is threadedly connected inside the sliding frame 31. The position of the sliding frame 31 is adjusted according to the usage environment and then fixed by the clamping plate 33. The clamping plate 33 can cooperate with the mounting plate 1 to fix the position of the mounting plate 1, stabilize the entire fixing device, and thus perform cleaning work. The mounting plate 1 has a matching groove at the corresponding position of the sliding frame 31, and the sliding frame 31 slides inside the groove. The second bolt 34 is in contact with the mounting plate 1. The sliding frame 31 has a groove at the corresponding position of the clamping plate 33, and the clamping plate 33 slides inside the groove. The second bolt 34 can fix the adjusted position of the sliding frame 31, thereby stabilizing the position of the sliding frame 31 and preventing the sliding frame 31 from sliding on its own.

[0024] During operation, the sliding frame 31 is pushed to slide inside the groove of the mounting plate 1, causing the sliding frame 31 to move the clamping plate 33 to a suitable fixed position. The second bolt 34 is twisted to abut against the mounting plate 1, increasing the friction between the second bolt 34 and the mounting plate 1, thereby fixing the position of the sliding frame 31 inside the groove. Then, the edge of the worktable is locked between the mounting plate 1 and the clamping plate 33. The second threaded rod 32 is twisted to raise the clamping plate 33, which, together with the mounting plate 1, clamps the edge of the worktable, thereby fixing the position of the mounting plate 1. The electric telescopic rod 4 drives the connecting plate 21 to rise and fall, allowing the brush 27 to be inserted into the inner tube. The drive motor 22 drives the rotating block 2. 3. The rotating block 23 drives the mounting rod 26 via the slider 25, which in turn drives the brush 27 to rotate and clean the inner surface of the inner tube. Twisting the first threaded rod 210 causes it to rotate and move up and down inside the threaded cylinder 29. The movement of the first threaded rod 210 drives the hinge seat 211, which pushes the slider 25 via the connecting rod 212. The slider 25 slides outside the limiting rod 24, which drives the mounting rod 26. The mounting rod 26 drives the brush 27, and the distance between the two brushes 27 is adjusted synchronously. Twisting and unscrewing the first bolt 28 allows the brush 27 to be unrestrained and removed for replacement.

[0025] Through the above steps, the distance between the two brushes 27 can be flexibly adjusted so that the two brushes 27 are adjusted to a suitable position according to the inner size of the inner tube, thereby fully contacting the inner surface of the inner tube. This solves the problem of mismatch between the size of the fixing rod and the inner tube of the gas spring, which leaves cleaning dead corners and results in incomplete cleaning.
