Description

Technical Field

[0001] This utility model relates to the field of viscous damper technology, specifically a viscous damper with a protective structure. Background Technology

[0002] A viscous damper is a passive vibration damping device that uses the damping properties of viscous fluids such as silicone oil or polymer materials to dissipate energy. It is widely used in construction, bridges, machinery and other fields to reduce the impact of vibration or impact loads. When the piston in the inner plate of the damper moves in the cylinder filled with viscous fluid, the fluid generates shear friction through small holes or gaps, converting mechanical energy into heat energy and dissipating it.

[0003] When the piston rod extends or retracts, the rod becomes sticky with adhesive, causing the sticky piston rod to be exposed and prone to dust and impurities from adhering to it. Therefore, we propose a viscous damper with a protective structure to improve upon the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a viscous damper with a protective structure to solve the problems mentioned in the background art.

[0006] As a further technical solution of this utility model, the protective sleeve carrying the connecting sleeve seat is sleeved on the outside of the piston rod, and the connecting sleeve seats at the top and bottom of the protective sleeve are sequentially sleeved with the bottom of the damping sleeve and the top of the movable lug.

[0007] As a further technical solution of this utility model, the fixing clamp is sleeved on the outside of the connecting sleeve, and the connecting sleeve is fixed to the bottom of the damping sleeve and the top of the movable lug.

[0009] As a further technical solution of this utility model, the aerogel layer is filled in the interlayer between the stainless steel outer layer and the copper alloy inner layer, and the copper alloy inner layer is arranged around the inside of the damping sleeve.

[0010] As a further technical solution of this utility model, the inner layer of the copper alloy is provided with a movable inner cavity, the movable inner cavity is filled with a viscous agent, a piston block is sleeved on the outside of the piston rod, a liquid guide port is opened inside the damping sleeve, and an outer sealing cap is sleeved on the outside of the liquid guide port.

[0011] As a further technical solution of this utility model, the piston rod carrying the piston block is inserted into the interior of the movable inner cavity, and the two sides of the piston block are filled with adhesive.

[0012] As a further technical solution of this utility model, the movable inner cavity is connected to the outside through the liquid guide port inside the damping sleeve, and two sets of liquid guide ports and outer sealing caps are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this kind of viscous damper with protective structure not only realizes the functions of telescopic protection and thermal insulation protection, but also realizes the function of easy replacement; (1) By setting a telescopic protective structure, the present invention is beneficial as follows: when in use, the protective sleeve is put on the outside of the piston rod at the bottom of the damping sleeve, and then the connecting sleeve at the upper and lower ends of the protective sleeve is put on the bottom of the damping sleeve and the top of the movable ear in sequence. Then, the connecting sleeve on the damping sleeve and the movable ear is fixed by the fixing clamp. When the movable ear extends and retracts at the bottom of the damping sleeve through the piston rod, the protective sleeve will also extend and retract outside the piston rod with the extension and retraction of the movable ear, thereby realizing the telescopic protective function. (2) By setting up a thermal insulation and protection structure, the advantages of this utility model are: the stainless steel outer layer set on the outside of the damping sleeve during use increases the protection of the outside of the damping sleeve, and the aerogel layer filled inside the damping sleeve has ultra-low thermal conductivity, which reduces the influence of external temperature on the viscous agent filled inside the active cavity, thereby realizing the thermal insulation and protection function. (3) By setting up a structure that is easy to replace, the present invention is beneficial in that: after long-term use of the viscous, the fluid may fail due to oxidation, pollution or leakage, and needs to be checked and replaced regularly. When in use, the outer sealing cap at the front end of the damping sleeve is separated from the liquid guide port.

[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] Please see Figure 1-4 An embodiment of this utility model is provided: a viscous damper with a protective structure, including a damping sleeve 2, a fixed lug 1 installed on the top of the damping sleeve 2, a piston rod 8 inserted into the bottom of the damping sleeve 2, a movable lug 4 connected to the bottom of the piston rod 8, an inner movable ring 5 installed inside the movable lug 4, a protective sleeve 3 sleeved on the outside of the piston rod 8, a connecting sleeve seat 6 provided at the top and bottom of the protective sleeve 3, and a fixed clamp 7 sleeved on the outside of the connecting sleeve seat 6; The protective sleeve 3, carrying the connecting sleeve 6, is fitted onto the outside of the piston rod 8. The connecting sleeve 6 at the top and bottom of the protective sleeve 3 is fitted onto the bottom of the damping sleeve 2 and the top of the movable lug 4 in sequence. The fixing clamp 7 is fitted onto the outside of the connecting sleeve 6. The connecting sleeve 6 is fixed to the bottom of the damping sleeve 2 and the top of the movable lug 4. Specifically, such as Figure 1 and Figure 2 As shown, by setting a telescopic protective structure, in use, the protective sleeve 3 is fitted onto the outside of the piston rod 8 at the bottom of the damping sleeve 2. Then, the connecting sleeve 6 at the upper and lower ends of the protective sleeve 3 is sequentially fitted onto the bottom of the damping sleeve 2 and the top of the movable lug 4. Then, the connecting sleeve 6 on the damping sleeve 2 and the movable lug 4 is fixed by the fixing clamp 7. When the movable lug 4 extends and retracts at the bottom of the damping sleeve 2 through the piston rod 8, the protective sleeve 3 will also extend and retract outside the piston rod 8 along with the extension and retraction of the movable lug 4, thereby realizing the telescopic protective function.

[0018] The damping sleeve 2 is fitted with a stainless steel outer layer 9, and the inner side of the damping sleeve 2 is provided with a copper alloy inner layer 11. The inner side of the stainless steel outer layer 9 is provided with an aerogel layer 10. Aerogel layer 10 is filled in the interlayer between stainless steel outer layer 9 and copper alloy inner layer 11, with copper alloy inner layer 11 surrounding the inside of damping sleeve 2. Specifically, such as Figure 1 and Figure 3 As shown, by setting up a thermal insulation and protection structure, the outer stainless steel layer 9 of the damping sleeve 2 during use increases the external protection of the damping sleeve 2. The inside of the damping sleeve 2 is filled with an aerogel layer 10, which has ultra-low thermal conductivity, reducing the influence of external temperature on the adhesive 13 filled inside the movable inner cavity 12, thereby achieving the thermal insulation and protection function.

[0019] The inner layer 11 of copper alloy has a movable inner cavity 12, which is filled with a viscous agent 13. The piston rod 8 is fitted with a piston block 15. The damping sleeve 2 has a liquid guide port 14 inside, and an outer sealing cap 16 is fitted outside the liquid guide port 14. The piston rod 8 carries the piston block 15 and is inserted into the interior of the movable inner cavity 12. The two sides of the piston block 15 are filled with adhesive 13. The movable inner cavity 12 is connected to the outside through the liquid guide port 14 inside the damping sleeve 2. Two sets of liquid guide ports 14 and outer sealing caps 16 are provided. Specifically, such as Figure 1 and Figure 4 As shown, by setting up a structure that facilitates replacement, after long-term use of the viscous 13, the fluid may fail due to oxidation, contamination or leakage, requiring regular inspection and replacement. During use, the outer sealing cap 16 at the front end of the damping sleeve 2 is separated from the liquid guide port 14. The viscous 13 on both sides of the piston block 15 inside the movable inner cavity 12 is discharged through the liquid guide port 14. After the new viscous 13 is injected into the movable inner cavity 12, the liquid guide port 14 is sealed again through the outer sealing cap 16, thus achieving the function of easy replacement.

[0020] Working Principle: This invention uses a protective sleeve 3 fitted over the piston rod 8 at the bottom of the damping sleeve 2. Then, the connecting sleeves 6 at the upper and lower ends of the protective sleeve 3 are sequentially fitted onto the bottom of the damping sleeve 2 and the top of the movable lug 4. The connecting sleeves 6 on the damping sleeve 2 and the movable lug 4 are then fixed with a fixing clamp 7. When the movable lug 4 extends and retracts at the bottom of the damping sleeve 2 via the piston rod 8, the protective sleeve 3 also extends and retracts outside the piston rod 8, connecting the fixed lug 1 and the movable lug 4 at the top of the damping sleeve 2. Finally, the stainless steel outer layer 9 on the outside of the damping sleeve 2 further enhances the damping effect. 2. External protection: The damping sleeve 2 is filled with an aerogel layer 10, which has ultra-low thermal conductivity, reducing the influence of external temperature on the viscous agent 13 filled inside the movable inner cavity 12. After long-term use, the fluid may fail due to oxidation, contamination or leakage, and needs to be checked and replaced regularly. When in use, the outer sealing cap 16 at the front end of the damping sleeve 2 is separated from the liquid guide port 14. The viscous agent 13 on both sides of the piston block 15 inside the movable inner cavity 12 is discharged through the liquid guide port 14. After the new viscous agent 13 is injected into the movable inner cavity 12, the liquid guide port 14 is sealed again through the outer sealing cap 16.
