Description

Technical Field

[0001] This utility model relates to the field of shock absorber recovery valve technology, and in particular to a shock absorber recovery valve with an improved structure. Background Technology

[0002] Shock absorbers are used to suppress the oscillations when the springs absorb shocks and the impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the car. When driving over uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves will still have reciprocating motion. Shock absorbers are used to suppress this spring jumping, and shock absorbers require the use of a return valve body.

[0003] The currently published patent, CN221097308U, discloses a recovery valve for a shock absorber. The recovery valve has multiple sealing components inside, which can seal the hydraulic oil inside the shock absorber. When the shock absorber is subjected to external impact force, the hydraulic oil can flow slowly under the action of the sealing components, thereby achieving the shock absorption effect. It can also restore the flow of hydraulic oil during the shock absorber's reset operation.

[0004] Based on the above search results, the recovery valve allows hydraulic oil to flow slowly under the action of the sealing components, thereby achieving a shock absorption effect. It also allows for the return flow of hydraulic oil during the shock absorber's reset operation. Although the shock absorber recovery valve ensures the discharge of hydraulic oil, the compression degree of the spring installed inside the valve is fixed. Therefore, the clamping force generated by the spring inside the shock absorber recovery valve is fixed. Since the pressure requirements for discharging hydraulic oil differ for hydraulic shock absorbers on different vehicles, a single shock absorber recovery valve can only be applied to hydraulic shock absorbers of the same vehicle class. This makes it inconvenient for users to adjust according to actual usage needs, resulting in a limited range of applicability and reduced practicality. Utility Model Content

This solves the problem that a shock absorber recovery valve can only be applied to hydraulic shock absorbers of the same vehicle class, which is inconvenient for users to adjust according to actual usage needs, resulting in a small range of application for the shock absorber recovery valve and reducing its practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock absorber recovery valve with an improved structure, comprising a cylinder and a recovery valve pressure regulating device; the recovery valve pressure regulating device comprises a through-hole block, a sliding plate, a guide rod, a sealing plug, a spring, and a long bolt. The through-hole block is fixedly connected to the inside of the cylinder, and a drain hole is opened on the surface of the through-hole block. Two grooves are opened on the inner wall of the cylinder, and the sliding plate is slidably connected to the inside of the two grooves. The guide rod is slidably sleeved inside the sliding plate. The sealing plug is fixedly connected to the upper end of the guide rod and slidably connected to the inside of the drain hole. The spring is slidably sleeved on the surface of the guide rod.

[0007] Preferably, a first fixing plate is fixedly connected to the surface of the cylinder, and a second fixing plate is provided on the right side of the first fixing plate.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-4This utility model provides a technical solution: a shock absorber recovery valve with an improved structure, including a cylinder 1 and a recovery valve pressure regulating device. A first fixed pressure plate 2 is fixedly connected to the surface of the cylinder 1, and a second fixed pressure plate 3 is provided on the right side of the first fixed pressure plate 2. A shock absorber 4 is installed inside the first fixed pressure plate 2 and the second fixed pressure plate 3. Two fixing bolts 5 are installed on the surface of the second fixed pressure plate 3, and two protrusions 6 are fixedly connected to the surface of the first fixed pressure plate 2. The two fixing bolts 5 are respectively installed inside the two protrusions 6.

[0026] After the worker takes out the cylinder 1, the first fixing plate 2 is installed on the surface of the shock absorber 4, and the second fixing plate 3 is installed on the surface of the shock absorber 4. The worker then uses a wrench to rotate the two fixing bolts 5, so that the two fixing bolts 5 are rotated and installed into the interior of the two protrusions 6, thereby fixing the first fixing plate 2 and the second fixing plate 3 together. The cylinder 1 can be fixedly installed on the surface of the shock absorber 4 by the first fixing plate 2 and the second fixing plate 3, which improves the convenience of the worker in installing the shock absorber's recovery valve.

[0027] The top of the cylinder 1 is fixedly connected to the inlet pipe 7, and the bottom of the cylinder 1 is fixedly connected to the outlet pipe 8. The pressure regulating device of the recovery valve includes a through-hole block 9, a sliding plate 12, a guide slide rod 13, a sealing plug 14, a spring 15, and a long bolt 16. The through-hole block 9 is fixedly connected to the inside of the cylinder 1. The surface of the through-hole block 9 is provided with an outlet hole 10. The inner wall of the cylinder 1 is provided with two slide grooves 11. The sliding plate 12 is slidably connected to the inside of the two slide grooves 11. The guide slide rod 13 is slidably sleeved inside the sliding plate 12. The sealing plug 14 is fixedly connected to the upper end of the guide slide rod 13 and slidably connected inside the outlet hole 10. The spring 15 is slidably sleeved on the surface of the guide slide rod 13. The upper end of the spring 15 is fixedly connected to the bottom of the sealing plug 14, and the lower end of the spring 15 is fixedly connected to the top of the sliding plate 12. The long bolt 16 is rotatably installed at the lower end of the cylinder 1, and the upper end of the long bolt 16 is threadedly installed inside the sliding plate 12.

[0028] When the operator needs to adjust the oil inlet pressure inside the cylinder 1 according to the requirements of the shock absorber 4, the operator can rotate the long bolt 16 with a wrench. The rotation of the long bolt 16 causes the slide plate 12 to slide up and down, and the slide plate 12 is positioned by the two sliding grooves 11 to ensure that the slide plate 12 slides vertically up and down inside the cylinder 1. When the slide plate 12 slides upward, it compresses the spring 15, increasing the degree of compression of the spring 15, which in turn increases the elastic force of the spring 15 on the sealing plug 14. The pressure of the sealing plug 14 pressing against the inside of the drain hole 10 increases. At this time, the operator can increase the hydraulic oil to push the sealing plug 14 downward and through. The pressure discharged into the cylinder 1 through the drain hole 10 is reduced. Conversely, the slide plate 12 slides downward, the compression of the spring 15 decreases, and the elastic force of the spring 15 on the sealing plug 14 decreases. The pressure required for the external hydraulic oil to be discharged into the cylinder 1 through the drain hole 10 is reduced. Through this adjustment method, the operator can adjust the pressure of the sealing plug 14 against the drain hole 10 to achieve the pressure required by the shock absorber 4. Therefore, this shock absorber return valve can be applied to hydraulic shock absorbers of different vehicle models, making it convenient for users to adjust according to actual usage needs, increasing the applicability of the shock absorber return valve and improving its practicality.
