[0002] Pneumatic rods have a wide range of applications in the field of clamps. Whether it is a height-adjustable swivel chair in the office, a comfortable bed in the bedroom, or even a practical cabinet in the kitchen, they all rely on the support of pneumatic rods. Pneumatic rods and their components may vibrate under the action of gas pressure. If there is an installation deviation or wear of the components, the vibration will be aggravated and accompanied by abnormal noise. In order to improve the user experience of furniture that uses pneumatic rods, it is necessary to design a buffer and noise reduction structure for them.

[0003] However, the following problems were found in the implementation of the relevant technologies: Although the existing pneumatic rod body has achieved noise reduction through structural optimization, the structure used for noise reduction is prone to wear after long-term use and is not convenient to replace. Utility Model Content

[0016] 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.

[0017] like Figures 1 to 5 As shown, this utility model provides a furniture pneumatic rod with a buffer and noise reduction structure, including a pneumatic rod body 1 and a buffer and noise reduction mechanism installed on the outside of the pneumatic rod body 1. The buffer and noise reduction mechanism includes two support shells 2, a first support pad 3, a support plate 4, a support block 5, two support rods 6, a spring 7, and multiple diagonal braces 8. The support shells 2 are sleeved on the outside of the pneumatic rod body 1, and the rear sides of the two support shells 2 are connected by hinges. The front sides of both support shells 2 are connected to connectors 15. A fixing screw is screwed between the two connecting parts 15. Unscrewing the fixing screw allows the two connecting parts 15 to be separated to open the two support housings 2. The first support pad 3 is located at the bottom inner side of the support housing 2, and the pneumatic rod body 1 is supported on top of the first support pad 3. The first support pad 3, together with the support housing 2, provides longitudinal cushioning for the pneumatic rod body 1, reducing noise caused by vibration. Two positioning blocks 14 are symmetrically bonded to the bottom of the first support pad 3, and the bottom inner side of the support housing 2 has positioning holes for inserting the positioning blocks 14. The first support pad 3 can be directly... Lift it upwards to remove it. The new first support pad 3 is aligned with the positioning hole by the positioning block 14 and then pressed to complete the installation. The support plate 4 is supported on the right side of the pneumatic rod body 1. The support plate 4 has an arc-shaped structure to ensure that it can fit close to the pneumatic rod body 1. The support plate 4 is made of sound-absorbing material, which can absorb and eliminate some of the noise of the pneumatic rod body 1. The support block 5 is integrally formed on the right side of the support plate 4. Two support rods 6 are threadedly connected side by side to the right side of the support block 5. The threaded connection method is convenient for disassembly and assembly, and is more convenient for subsequent maintenance. The support rods 6 can be movably inserted into the support. On the corresponding side of the support housing 2, the spring 7 is sleeved on the side wall of the support rod 6, and the spring 7 is connected between the support block 5 and the corresponding side of the support housing 2. The spring 7 buffers the support block 5 and the support plate 4 through its own elastic deformation. Together with the corresponding side of the support housing 2, it can provide lateral buffering for the pneumatic rod body 1. Multiple inclined support blocks 8 are distributed in a ring shape and connected to the corresponding side of the outer wall of the support housing 2. The multiple inclined support blocks 8 can stably support the support housing 2, ensuring that the support housing 2 will not shake, improving the overall stability, and helping to improve the buffering performance.

[0018] Specifically, a clamping rod 9 is screwed onto the right side wall of the support housing 2, and the clamping rod 9 is located between the two support rods 6. Tightening the clamping rod 9 can make its left end press against the support block 5, so that the support plate 4 can work with the support housing 2 to completely press against the pneumatic rod body 1. In scenarios where there are higher stability requirements for the pneumatic rod body 1, its stability can be increased, but the lateral buffering performance will be worse and the noise will be slightly increased.

[0019] Furthermore, the right end of the clamping rod 9 is connected to a gripper 10 by a screw, which facilitates the application of force to tighten the clamping rod 9, making it easier to tighten the clamping rod 9. The right end of the support rod 6 is connected to a limiter by a screw, ensuring that the support rod 6 can always be inserted into the corresponding side of the support housing 2.

[0020] It is worth noting that the side of the diagonal brace 8 away from the supporting shell 2 is integrally formed with a fixing member 16, and the middle part of the fixing member 16 has a fixing hole 12. Adding screws in the fixing hole 12 can increase the stability of the diagonal brace 8. The combination of multiple structures can further increase the overall stability.

[0021] It is worth noting that the support block 5 and the support plate 4, as well as the diagonal brace 8 and the fixing part 16, are all injection molded as a single unit. The injection molded as a single unit has a more stable structure and is not easily damaged after long-term use.

[0022] It is worth mentioning that a second support pad 11 is bonded to the bottom of the support housing 2, and the second support pad 11 is flush with the bottom of the diagonal brace 8 and the fixing member 16, which can improve the longitudinal buffer and help improve the buffer performance.

[0023] It is worth emphasizing that a label 13 is attached to the front outer wall of the support housing 2. The label 13 is marked with the current specifications of the pneumatic rod body 1, which makes it easy for maintenance personnel to understand quickly. In addition, a protective film is attached to the surface of the label 13, which can prevent the specification information from becoming blurred due to wear and tear.

[0024] The front, back, left, and right perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0025] Working principle: The pneumatic rod body 1 is installed inside the support housing 2 (e.g., Figure 1 The support housing 2, together with the first support pad 3 and the second support pad 11, provides longitudinal buffering for the pneumatic rod body 1. The two springs 7 can buffer the support block 5 and the support plate 4 through their own elastic deformation. Together with the corresponding side of the support housing 2, they can provide lateral buffering for the pneumatic rod body 1. In addition, multiple diagonal braces 8, together with the fixing parts 16, can stably support the support housing 2, which can help improve the buffering performance. The above structure can provide sufficient buffering for the pneumatic rod body 1 and further reduce the noise generated by vibration.

[0026] When the buffer-related structure needs to be replaced, first unscrew the fixing screws to separate the two connecting parts 15 to open the two support housings 2. Then unscrew the support rod 6 to remove the support block 5, support plate 4, and spring 7. After removing the pneumatic rod body 1, lift it up to remove the first support pad 3. Close the two support housings 2 and screw in the fixing screws to fix them. After the new first support pad 3 is aligned with the positioning hole by the positioning block 14, press it to complete the installation. Then, put the new spring 7 on the side wall of the support rod 6 and screw it into the right side of the new support block 5. Temporarily press the support plate 4 to the right and hold it. After placing the pneumatic rod body 1 on its left side, release it. The support plate 4 will then press against the right side of the pneumatic rod body 1 due to the spring 7 returning to its original position. This completes the replacement of the noise reduction structure.
