Description

Technical Field

[0001] The utility model relates to the field of shock-absorbing rods, in particular to a shock-absorbing rod capable of preventing friction between a piston and a bottom cylinder. Background Art

[0002] A shock absorber, also known as a shock absorber, is a device used to reduce vibration in machinery or structures. It absorbs and dissipates energy to reduce vibration amplitude, thereby protecting the equipment or structure from damage caused by excessive vibration. It also improves the user experience, such as reducing noise and discomfort. When an object vibrates, the internal structure of the shock absorber undergoes relative motion. For example, a common hydraulic shock absorber consists primarily of a piston, a cylinder, and oil. As the piston moves up and down within the cylinder, the oil flows through small holes or valves in the piston. This flow creates resistance, converting the mechanical energy of the vibration into heat energy, thereby achieving the desired shock absorption effect.

[0003] The traditional piston currently used will rub against the bottom cylinder for a long time, causing the shock absorber rod to become sticky and extremely inconvenient to use.

[0004] In view of this, research and improvements are conducted on the existing problems, and a shock absorber rod is provided to prevent friction between the piston and the bottom cylinder. The shock absorber rod has a reasonable structural design, eliminates the traditional piston structure, avoids friction between the piston and the bottom cylinder, and thus eliminates the phenomenon of the shock absorber rod becoming sticky and stuck. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a shock-absorbing rod which can prevent friction between a piston and a bottom cylinder.

[0007] As a further description of the above technical solution:

[0008] The rotating shaft seat is rotatably connected to the bottom of the bottom cylinder, and the size of the rotating shaft seat is adapted to the size of the bottom cylinder. The end cover body is detachably mounted on the top of the front fork tube, and the size of the end cover body is adapted to the size of the front fork tube.

[0009] As a further description of the above technical solution:

The guide plug A and the guide plug B have the same size, and the guide plug A and the guide plug B are arranged between the front fork tube and the base tube.

[0011] As a further description of the above technical solution:

[0012] The oil seal is slidably connected to the inner wall of the support tube, and the oil seal is movably connected to one side of the guide plug B. The wire loop is wound between the front fork tube and the bottom tube, and the shape of the wire loop is cylindrical.

[0014] The dust seal is fixedly connected to the top of the wire ring, the dust seal is arranged on the outside of the front fork tube, and the built-in damper is movably connected to the inside of the front fork tube.

[0015] The utility model has the following beneficial effects:

[0016] The shock absorber's structural design significantly reduces friction between the plug and the base barrel during use, thereby reducing heat and wear caused by friction. The built-in damper effectively absorbs and disperses vibration energy, enhancing the shock absorber's damping effectiveness. A dust seal effectively prevents dust and impurities from entering the shock absorber, ensuring clean and normal operation of the equipment.

[0017] The use of an oil seal not only prevents lubricant leakage but also ensures that the shock absorber rod remains well lubricated in all conditions.

[0024] Reference Figure 1-2 The utility model provides an embodiment: a shock absorber rod for preventing friction between a piston and a bottom cylinder, comprising a bottom cylinder 1, a rotating shaft seat 11 being installed at the bottom of the bottom cylinder 1, a support cylinder 2 being provided on the inner side of the bottom cylinder 1, a guide plug A3 being provided at the bottom of the support cylinder 2, a guide plug B4 being installed at the top of the support cylinder 2, an oil seal 5 being provided above the guide plug B4, a wire ring 6 being installed at the upper end of the oil seal 5, a dust seal 7 being provided on the surface of the wire ring 6, a front fork tube 9 being provided on the inner side of the support cylinder 2, a built-in damper 8 being installed inside the front fork tube 9, and an end cover body 10 being installed on the top of the front fork tube 9.

[0025] In the present invention, the shaft seat 11 is rotatably connected to the bottom of the base tube 1. The size of the shaft seat 11 is compatible with the size of the base tube 1. The end cap 10 is removably mounted on the top of the front fork tube 9. The size of the end cap 10 is compatible with the size of the front fork tube 9. When the built-in damper 8 needs to be replaced or maintained, the end cap 10 can be easily removed without disassembling the entire shock absorber structure. The adaptive design of the shaft seat 11 ensures a stable connection between the base tube 1 and the shaft seat 11, thereby improving the durability and reliability of the entire shock absorber.

[0026] Furthermore, the support tube 2 is movably connected to the interior of the base tube 1. The support tube 2 is cylindrical in shape. The guide plug A3 is fixedly connected to the bottom of the support tube 2, and the guide plug B4 is fixedly connected to the top of the support tube 2. The guide plugs A3 and B4 are identical in size. They are positioned between the front fork tube 9 and the base tube 1, effectively guiding the movement of the shock absorber rod during operation and ensuring smooth operation. Furthermore, because the guide plugs A3 and B4 are identical in size, they can be used interchangeably, increasing the maintenance flexibility and cost-effectiveness of the shock absorber rod. This design also reduces wear caused by friction and extends the service life of the shock absorber rod.

[0027] Furthermore, the oil seal 5 is slidably connected to the inner wall of the support tube 2. The oil seal 5 is movably connected to one side of the guide plug B4. The wire coil 6 is wound between the front fork tube 9 and the bottom tube 1. The wire coil 6 is cylindrical in shape, which can effectively prevent oil leakage and maintain the lubrication state inside the shock absorber rod. The sliding connection design of the oil seal 5 allows it to move freely on the inner wall of the support tube 2, so that when the shock absorber rod is working, the oil seal 5 can adapt to different movement states and ensure the sealing effect. At the same time, the movably connected oil seal 5 and the guide plug B4 means that when the guide plug B4 guides the movement of the shock absorber rod, the oil seal 5 will not hinder the movement of the guide plug B4, ensuring the smooth operation of the shock absorber rod. The provision of the wire coil 6 further strengthens the fixation between the front fork tube 9 and the bottom tube 1, preventing relative displacement between the two, thereby improving the stability of the entire shock absorber rod structure.

[0028] Furthermore, the dust seal 7 is fixedly connected to the top of the wire loop 6 and is disposed on the outside of the front fork tube 9. The built-in damper 8 is movably connected to the inside of the front fork tube 9. The dust seal 7 can effectively prevent external dust and impurities from entering the shock absorber rod, keeping the internal environment clean, thereby extending the service life of the shock absorber rod. The built-in damper 8 automatically adjusts the damping force according to the operating status of the shock absorber rod to ensure the stability and reliability of the shock absorption effect. When the shock absorber rod is impacted, the built-in damper 8 can respond quickly and provide appropriate resistance to absorb and disperse the impact energy, protecting the mechanical structure from damage.

[0029] Working principle and usage process:

[0030] In this utility model, the shock absorber rod operates by absorbing and dissipating vibration energy through a built-in damper 8, thereby reducing friction between the plug and the base tube. When external vibration is applied, the built-in damper 8 effectively absorbs the vibration energy, reducing the transmission of vibration to the support tube 2 and the guide plugs A3 and B4. The consistent dimensions of the guide plugs A3 and B4 ensure that they can slide stably between the front fork tube 9 and the base tube 1 during vibration without generating excessive friction.

[0031] The sliding connection of oil seal 5 allows it to move freely on the inner wall of support tube 2 while maintaining a seal to prevent liquids and impurities from entering the internal structure. The winding method of wire ring 6 provides a certain degree of elasticity for the shock absorber rod, further reducing the impact of vibration on base tube 1. Dust seal 7 is fixed on the top of wire ring 6 to protect the internal structure from the intrusion of dust and foreign matter.

[0032] To use the device, first install the shock absorber on the equipment requiring vibration damping, ensuring that the shaft seat 11 fits snugly and securely into the equipment's connection. Then, adjust the end cap 10 on the front fork tube 9 as needed to suit different operating environments and requirements. During operation, the built-in damper 8 begins to absorb and dissipate vibration energy. Guide plugs A3 and B4 slide between the front fork tube 9 and the base barrel 1. The oil seal 5 and wire ring 6 work together to maintain stable operation, while the dust seal 7 ensures cleanliness of the internal structure. Through this workflow, the shock absorber effectively protects the equipment and extends its service life.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
