Description

Technical Field

[0001] This utility model relates to the field of damper technology, and in particular to a damper. Background Technology

[0002] Application number CN202420185920.4 discloses a vibration damper, comprising a base plate with two symmetrical curved plates welded to its upper surface. A vertically movable sliding plate is provided on the inner side of each curved plate. A receiving plate is fixedly installed at the top of the sliding plate, and rubber strips are fixedly installed on the outer side of the sliding plate. Grooves matching the number of rubber strips are formed on the inner side of each curved plate. A threaded rod is spirally installed on the receiving plate, with a first positioning plate at the bottom end of the threaded rod. A second positioning plate is provided on the upper surface of the base plate, and a spring is fixedly installed between the first and second positioning plates. This invention, by incorporating the sliding plate, curved plates, rubber strips, and grooves, reduces friction between the sliding plate and curved plates during vibration damping operation through the guidance of the rubber strips and grooves, thereby reducing damage and noise.

[0003] The existing dampers reduce friction between the sliding plate and the curved plate by guiding the rubber strip and the groove, thus reducing damage and noise. However, the rubber strip will wear out severely after repeated use because a single spring is insufficient to offset the pressure on the support plate. To solve this problem, we propose a damper with multi-stage buffering effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a damper to solve the technical problem that "when the existing damper is used for shock absorption, the friction between the slide plate and the curved plate is reduced by the guidance of the rubber strip and the groove, which reduces damage and noise. However, the rubber strip will wear out severely after repeated use because a single spring is insufficient to offset the pressure on the support plate. To solve this problem, we propose a damper with multi-stage buffering effect."

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A damper includes a receiving plate and an anti-slip pad.

[0007] Multiple No. 2 damping springs are arranged in a ring at equal intervals between the receiving plate and the anti-slip pad. The lower end of each No. 2 damping spring is fixedly installed on the anti-slip pad, and the upper end of each No. 2 damping spring is fixedly installed on the receiving plate. The No. 2 damping springs improve the buffering capacity of the damper. A sliding sleeve is fixedly installed on the lower end face of the receiving plate. A sliding column is vertically slidably connected inside the sliding sleeve. A fixing plate is fixedly installed on the side wall of the sliding column. The fixing plate is vertically slidably connected in the inner wall of the sliding sleeve. The fixing plate is used to limit the movement trajectory of the sliding sleeve, so that it slides up and down along the limiting groove. A limiting groove matching the fixing plate is opened on the inner wall of the sliding sleeve. The fixing plate is slidably connected in the limiting groove, so that there is vertical relative movement between the sliding column and the sliding sleeve.

[0008] The upper end face of the sliding column is provided with a threaded groove, and a matching threaded rod is threadedly connected in the threaded groove. A connecting column is fixedly installed at the upper end of the threaded rod. The upper end of the connecting column passes through the upper end face of the receiving plate and is fixedly installed with a knob. By rotating the threaded rod, the sliding sleeve is driven to rise or fall, thereby adjusting the distance between the receiving plate and the anti-slip pad.

[0009] A pressure plate is slidably connected inside the anti-slip pad. Multiple No. 1 damping springs are fixedly installed in a ring on the lower end face of the pressure plate. The lower end of each No. 1 damping spring is fixedly installed on the bottom end face inside the mounting sleeve. The upper end of the pressure plate is fixedly connected to the lower end of the sliding column. The lower end of the sliding column extends through the upper end face of the mounting sleeve into the mounting sleeve and is slidably connected to the mounting sleeve.

[0010] The upper end face of the connecting column is provided with a threaded groove, and a matching threaded rod is threadedly connected in the threaded groove. The upper end of the threaded rod is fixedly installed with the connecting column. The upper end of the connecting column passes through the upper end face of the receiving plate and is fixedly installed with a knob. By rotating the threaded rod, the sliding sleeve is driven to rise or fall, thereby adjusting the distance between the receiving plate and the anti-slip pad.

[0011] A pressure plate is slidably connected inside the anti-slip pad. Multiple No. 1 damping springs are fixedly installed in a ring on the lower end face of the pressure plate. The lower end of each No. 1 damping spring is fixedly installed on the bottom end face inside the support plate. The upper end of the pressure plate is fixedly connected to the lower end of the connecting column. The lower end of the connecting column extends through the upper end face of the support plate into the support plate and is slidably connected to the support plate.

[0012] As a preferred embodiment of this utility model, the diameter of the sliding column is smaller than the inner diameter of the sliding sleeve, so that there is a gap between the sliding sleeve and the sliding column, which facilitates the air circulation inside the sliding sleeve.

[0013] As a preferred embodiment of this utility model, the connecting column and the receiving plate are rotatably connected, and the receiving plate is provided with a through hole that matches the connecting column, and the connecting column and the through hole are rotatably connected.

[0014] As a preferred embodiment of this utility model, the number of the first damping spring and the second damping spring is set to one, and the first damping spring and the second damping spring together provide buffering for the receiving plate.

[0015] As a preferred embodiment of this utility model, the connecting post and the threaded rod are integrally formed, and the connecting post is welded to the center of the bottom end face of the knob.

[0016] As a preferred embodiment of this utility model, the diameter of the pressure plate is smaller than the inner diameter of the mounting sleeve, and there is a gap between the pressure plate and the inner wall of the mounting sleeve.

[0017] This utility model provides a damper with the following beneficial effects:

[0018] The No. 2 damping spring provides primary buffering for the support plate and anti-slip pad, while the No. 1 damping spring provides secondary buffering for both the anti-slip pad and support plate. Through multiple levels of buffering, the damping effect of the damper is increased. Attached Figure Description

[0023] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0025] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments:

[0026] refer to Figure 1-3 A damper includes a receiving plate 7 and an anti-slip pad 13.

[0027] Multiple second-order damping springs 12 are arranged in a ring at equal intervals between the receiving plate 7 and the anti-slip pad 13. The lower end of each second-order damping spring 12 is fixedly installed on the anti-slip pad 13, and the upper end of each second-order damping spring 12 is fixedly installed on the receiving plate 7. The second-order damping springs 12 improve the buffering capacity of the damper. A sliding sleeve 8 is fixedly installed on the lower end face of the receiving plate 7. A sliding column 14 is vertically slidably connected inside the sliding sleeve 8. A fixing plate 4 is fixedly installed on the side wall of the sliding column 14. The fixing plate 4 is vertically slidably connected in the inner wall of the sliding sleeve 8. The fixing plate 4 is used to limit the movement trajectory of the sliding sleeve 8, so that it slides up and down along the limiting groove 9. A limiting groove 9 matching the fixing plate 4 is opened on the inner wall of the sliding sleeve 8. The fixing plate 4 is slidably connected in the limiting groove 9, so that there is vertical relative movement between the sliding column 14 and the sliding sleeve 8.

[0028] The upper end face of the sliding column 14 is provided with a threaded groove 2, and a matching threaded rod 3 is threadedly connected in the threaded groove 2. A connecting column 5 is fixedly installed at the upper end of the threaded rod 3. The upper end of the connecting column 5 passes through the upper end face of the receiving plate 7 and a knob 6 is fixedly installed. By rotating the threaded rod 3, the sliding sleeve 8 is driven to rise or fall, thereby adjusting the distance between the receiving plate 7 and the anti-slip pad 13.

[0029] A pressure plate 11 is slidably connected inside the anti-slip pad 13. Multiple first-order damping springs 10 are fixedly installed in a ring on the lower end face of the pressure plate 11. The lower end of each first-order damping spring 10 is fixedly installed on the bottom end face inside the mounting sleeve 1. The upper end of the pressure plate 11 is fixedly connected to the lower end of the sliding column 14. The lower end of the sliding column 14 extends through the upper end face of the mounting sleeve 1 into the mounting sleeve 1 and is slidably connected to the mounting sleeve 1. By rotating the knob 6, the knob 6 drives the connecting column 5 to rotate, and the connecting column 5 drives the threaded rod 3 to rotate, so that the sliding column 14 can move up and down in the sliding sleeve 8, thereby adjusting the distance between the receiving plate 7 and the anti-slip pad 13 and changing the shape of the second-order damping spring 12, so that the damper buffer strength can be adjusted as needed.

[0030] The diameter of the sliding column 14 is smaller than the inner diameter of the sliding sleeve 8, so that there is a gap between the sliding sleeve 8 and the sliding column 14, which facilitates the air circulation inside the sliding sleeve 8.

[0031] The connecting column 5 is rotatably connected to the receiving plate 7, and the receiving plate 7 has a through hole that matches the connecting column 5. The connecting column 5 is rotatably connected to the through hole.

[0032] The number of damping springs 10 and 12 is set to 4 each. The damping springs 10 and 12 together buffer the receiving plate 7, enhancing the effect of the damper.

[0033] The connecting post 5 and the threaded rod 3 are integrally formed, and the connecting post 5 is welded to the center of the bottom end face of the knob 6, which enhances the connection strength between the connecting post 5 and the threaded rod 3 and extends the service life of the threaded rod 3.

[0034] The diameter of the pressure plate 11 is smaller than the inner diameter of the mounting sleeve 1, and there is a gap between the pressure plate 11 and the inner wall of the mounting sleeve 1 to ensure pressure balance inside the mounting sleeve 1.

[0035] Specifically, when the receiving plate 7 and the anti-slip pad 13 are under pressure, they will compress the second damping spring 12 in the middle. The second damping spring 12 provides a first-level buffer for the receiving plate 7 and the anti-slip pad 13. Then, the receiving plate 7 and the anti-slip pad 13 compress the middle sliding sleeve 8 and the mounting sleeve 1. The sliding sleeve 8 compresses the first damping spring 10 through the pressure plate 11 at the lower end of the sliding column 14. The first damping spring 10 simultaneously provides a second-level buffer for the anti-slip pad 13 and the receiving plate 7. Through multiple levels of buffering, the buffering effect of the damper is increased.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
