Description

Technical Field

[0001] This utility model relates to the field of vibration damping equipment, specifically to an improved vibration damper. Background Technology

[0002] Spring vibration dampers employ a multi-spring combination design and can be customized to different specifications according to user needs. They are suitable for heavy machinery, cooling towers, fire pumps and valves, electrical equipment, and other applications. They offer advantages such as high flexibility, good stability, low natural frequency, and significant vibration reduction effect, and can be directly placed under equipment during installation.

[0003] Existing shock absorbers are guided only by guide rods (or studs) on both sides, making them prone to bending or breaking under large lateral forces.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The main purpose of this invention is to provide an improved vibration damper that can resist greater lateral forces and improve the stability of the vibration damper.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] An improved vibration damper includes a lower seat, an upper seat, and a damping spring located between the upper seat and the lower seat. Guide posts are respectively provided on both sides of the lower seat, and a transverse limiting plate is provided on the upper part of each guide post. A limiting groove is provided on the side of the transverse limiting plate facing away from the damping spring. Downward-extending limiting plates are respectively provided on both sides of the upper seat, and the limiting plates are slidably disposed in the limiting grooves of the corresponding transverse limiting plates. The transverse limiting plates have limiting ear plates located on both sides of the limiting plates.

[0008] Furthermore, the upper end of the limiting plate is welded to the upper seat; the transverse limiting plate, guide column and lower seat are welded together.

[0009] Furthermore, the lateral limiting plate has a limiting block extending laterally to the side of the guide post, the limiting block being located at the edge of the limiting groove; a limiting screw is installed on the limiting plate, the end of the limiting screw being located below the limiting block to limit the maximum upward stroke of the upper body.

[0010] Furthermore, each limiting plate is provided with two screw holes, and each screw hole is equipped with a limiting screw; the two screw holes are at the same horizontal height.

[0011] Furthermore, the distance between the edge of the limiting plate and the edge of the corresponding limiting groove is 1-3mm.

[0012] Furthermore, a transverse connecting plate is welded between the two guide posts; the damping spring is located in the area enclosed by the guide posts and the transverse connecting plate.

[0013] Furthermore, the upper and lower ends of the damping spring are respectively provided with an upper pressure plate and a lower pressure plate. The lower pressure plate is fixedly connected to the lower seat body, and the upper pressure plate is fixedly connected to the connecting plate. The upper seat body extends downward and is provided with a first screw. The first screw passes through the upper pressure plate and the connecting plate and is fixedly connected by a first nut on the first screw.

[0014] Furthermore, the first screw has two parts, and each first screw is provided with two first nuts, which are located on the upper surface of the connecting plate and the lower surface of the pressure plate, respectively.

[0015] Furthermore, there are two damping springs arranged side by side between the upper pressure plate and the lower pressure plate; two second screws extend upward from the lower base, the second screws pass through the lower pressure plate and are fixedly connected by a second nut on the second screw; each damping spring is coaxially arranged with the first screw and the second screw.

[0017] With the above structure, the improved vibration damper of this utility model has at least the following beneficial effects:

[0018] 1. Through the lateral limiting effect of the limiting plate and the limiting groove of the lateral limiting plate, when the upper body receives a large lateral force, the lateral limiting plate will abut against the limiting plate to limit the lateral displacement of the upper body, thus making the shock absorber more stable.

[0019] 2. Lateral displacement in the front-to-back direction is limited by two limiting lugs. Lateral displacement in the left-to-right direction is limited by a limiting upright plate and two guide posts located between the two limiting upright plates.

[0020] Third, by using the limiting screw and the limiting block of the transverse limiting plate below, the maximum stroke of the upper seat body relative to the lower seat body is limited, thus preventing the upper seat body from coming off.

[0021] Fourth, the transverse connecting plate improves the stability of the two guide pillars, and the area formed limits the damping spring to prevent it from coming off laterally.

[0022] 5. The upper pressure plate and the connecting plate are fixedly connected and formed into a stable whole by the upper and lower locking of the first nut. The position of the first nut on the first screw can be changed to adjust the height of the upper body relative to the lower body to adapt to the on-site installation environment.

[0023] Compared with the prior art, this utility model has a sliding connection between the limiting plate and the limiting groove on the transverse limiting plate, which can withstand a larger transverse force and improve the transverse stability of the upper body. Attached Figure Description

[0035] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0036] like Figures 1 to 7As shown, this is an improved vibration damper according to the present invention, including a lower seat 1, an upper seat 2, and a damping spring 3 located between the upper seat 2 and the lower seat 1. Guide posts 11 are respectively provided on both sides of the lower seat 1, and a transverse limiting plate 12 is provided on the upper part of each guide post 11. A limiting groove 121 is provided on the side of the transverse limiting plate 12 facing away from the damping spring 3. A downwardly extending limiting plate 21 is respectively provided on both sides of the upper seat 2. The limiting plate 21 is slidably disposed in the limiting groove 121 of the corresponding transverse limiting plate 12. The transverse limiting plate 12 has limiting ear plates 122 located on both sides of the limiting plate 21. Preferably, the upper end of the limiting plate 21 is welded to the upper seat 2; the transverse limiting plate 12, the guide posts 11, and the lower seat 1 are welded together integrally.

[0037] Thus, the improved vibration damper of this utility model, through the lateral limiting effect of the limiting plate 21 and the limiting groove 121 of the lateral limiting plate 12, when the upper body 2 receives a large lateral force, the lateral limiting plate 12 will abut against the limiting plate 21 to limit the lateral displacement of the upper body 2, thereby making the vibration damper have better stability.

[0038] Lateral displacement in the front-to-back direction is limited by two limiting lugs 122. Lateral displacement in the left-to-right direction is limited by limiting uprights 21 and two guide posts 11 located between the two limiting uprights 21.

[0039] Preferably, the transverse limiting plate 12 has a limiting block 123 extending laterally to the side of the guide post 11, the limiting block 123 being located at the edge of the limiting groove 121; a limiting screw 212 is installed on the limiting plate 21, the end of the limiting screw 212 being located below the limiting block 123 to limit the maximum upward stroke of the upper seat 2. By using the limiting screw 212 and the limiting block 123 of the transverse limiting plate 12, the maximum stroke of the upper seat 2 relative to the lower seat 1 is limited, preventing the upper seat 2 from dislodging.

[0040] Furthermore, each limiting plate 21 is provided with two screw holes 211, and each screw hole 211 is fitted with a limiting screw 212; the two screw holes 211 are at the same horizontal height. By providing two limiting screws 212 on the limiting plate 21, which work together with the limiting block 123, the system is safer and more stable.

[0041] Preferably, the distance between the edge of the limiting plate 21 and the edge of the corresponding limiting groove 121 is 1-3mm. Specifically, the distance between the limiting plate 21 and the limiting ear plate 122 and the limiting block 123 is 1-3mm; this ensures the smoothness of the upper body 2 during its up-and-down movement, and also restricts lateral movement in a timely manner when subjected to lateral force, avoiding excessive lateral movement.

[0042] Preferably, a transverse connecting plate 13 is welded between the two guide posts 11; the damping spring 3 is located within the area enclosed by the guide posts 11 and the transverse connecting plate 13. The transverse connecting plate 13 improves the stability of the two guide posts 11, and the area it forms limits the damping spring 3, preventing it from coming off laterally. The lower seat 1 is connected to the ground or a fixed object through the mounting hole 16.

[0043] Preferably, the damping spring 3 has an upper pressure plate 31 and a lower pressure plate 32 at its upper and lower ends, respectively. The lower pressure plate 32 is fixedly connected to the lower seat 1, and the upper pressure plate 31 is fixedly connected to the connecting plate 311. The upper seat 2 extends downward and is provided with a first screw 22. The first screw 22 passes through the upper pressure plate 31 and the connecting plate 311 and is fixedly connected by a first nut 221 on the first screw 22. There are two first screws 22, and each first screw 22 is provided with two first nuts 221. The two first nuts 221 are located on the upper surface of the connecting plate 311 and the lower surface of the lower pressure plate 32, respectively.

[0044] The upper pressure plate 31 is fixedly connected to the connecting plate 311, and a stable whole is formed by the upper and lower locking of the first nut 221. By changing the position of the first nut 221 on the first screw 22, the height of the upper seat 2 relative to the lower seat 1 can be adjusted to adapt to the on-site installation environment.

[0045] Preferably, two damping springs 3 are arranged side-by-side between the upper pressure plate 31 and the lower pressure plate 32; two second screws 14 extend upward from the lower base 1, passing through the lower pressure plate 32 and fixedly connected by a second nut 141 on the second screw 14; each damping spring 3 is coaxially arranged with the first screw 22 and the second screw 14. The two damping springs 3 work together to withstand greater vertical force.

[0046] Preferably, the upper seat 2 is provided with a connecting hole 23, and a connecting bolt is provided in the connecting hole 23; a first rubber pad 24 and a second rubber pad 15 are respectively provided on the upper part of the upper seat 2 and the lower part of the lower seat 1. The connection to the equipment is achieved through the connecting hole 23. The first rubber pad 24 and the second rubber pad 15 serve a cushioning function.

[0047] Compared with the prior art, the present invention, by setting the limiting plate 21 to slide and connect with the limiting groove 121 on the transverse limiting plate 12, can withstand a larger transverse force and improve the transverse stability of the upper body 2.

[0048] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
