Description

Technical Field

[0001] This utility model relates to the field of display rack technology, and specifically to a display rack vibration damping device. Background Technology

[0002] The existing display racks do not have good mobility and mostly rely on manual moving for relocation, which is physically demanding. Some display racks do have mobility, but once moved to the appropriate position, they mostly do not have good fixation. When someone accidentally bumps into the display rack, it will shake.

[0003] For example, utility model patent CN222565485U describes a display rack with a shock-absorbing structure, including a display rack body, a display support frame, and display placement boards. Support seats are installed around the bottom of the display support frame, and casters are installed on the bottom of each support seat. Fixed sliders are symmetrically installed on the bottom of the front and rear faces of the outer walls of the support seats. Limiting and fixing mechanisms are slidably installed on the support seats via these fixed sliders. Shock-absorbing spring mechanisms are vertically connected downwards to the middle of both sides of the bottom of the display support frame, and a fixing mechanism is vertically connected downwards at the bottom of the shock-absorbing spring mechanisms. In this utility model, the stability of the display rack body when not moving is achieved through the limiting and fixing mechanisms, preventing displacement and shaking. The shock-absorbing spring mechanisms then provide shock absorption for the display rack body and the items on the display placement boards.

[0004] In this technical solution, the shock-absorbing spring mechanism is unable to quickly buffer and offset the vibration when it is used to dampen the items on the display board.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a display rack vibration damping device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a display rack vibration damping device, comprising: a base, and a vibration damping mechanism for buffering the vibration of the display rack; The vibration damping mechanism includes: a mounting frame, a limiting groove on the mounting frame, and a limiting rod sliding through the mounting frame; a mounting plate fixedly connected to the limiting rod; and an elastic metal sheet fixedly mounted on the mounting plate; a sliding block slidably mounted in the limiting groove; and a V-shaped plate fixedly mounted on the sliding block.

[0008] Furthermore, the inner side of the V-shaped plate is in close contact with the elastic metal sheet.

[0009] Furthermore, the sliding block is provided with multiple through holes, and the mounting bracket is provided with multiple threaded holes.

[0010] Furthermore, the diameter of the through hole is larger than that of the threaded hole.

[0011] Furthermore, a bolt is threaded into the threaded hole.

[0012] Furthermore, a brake plate is installed on the inner side of the V-shaped plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a display rack vibration damping device, which uses the bending deformation of the elastic metal plate to make the elastic metal sheet tightly adhere to the inner side of the V-shaped plate. When the device is subjected to vibration, the elastic metal sheet further deforms to buffer the vibration. At the same time, friction is generated between the elastic metal sheet and the inner side of the V-shaped plate to consume the energy generated by the vibration and quickly eliminate the vibration.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 3 As shown, this utility model discloses a display rack vibration damping device, comprising: a base 1; a vibration damping mechanism 4 for buffering the vibration of the display rack; an electric telescopic rod 2 is installed at the center of the top of the base 1, and a placement plate 3 is installed on the movable rod of the electric telescopic rod 2. The height of the placement plate 3 can be adjusted by the electric telescopic rod 2, so that the height of the display rack can be freely changed to accommodate different people or display items; when the display rack vibrates due to external force, the vibration damping mechanism 4 quickly eliminates the vibration of the placement plate 3, thereby protecting the display items.

[0022] The vibration damping mechanism 4 includes: a mounting frame 41, which is fixedly mounted on the base 1, with two mounting frames 41 symmetrically distributed. Each mounting frame 41 has a limiting groove 42, and a vertical limiting rod 43 slides through and passes through the mounting frame 41. The upper end of the limiting rod 43 is fixedly connected to the bottom of the display panel, limiting the display panel to prevent rotation or shaking. The lower end of the limiting rod 43 is fixedly connected to a horizontal mounting plate 44, and an elastic metal sheet 45 is fixedly mounted on the top of the mounting plate 44 near the mounting frame 41. A sliding block 47 is slidably mounted in the limiting groove 42, and a V-shaped plate 46 is fixedly mounted on the sliding block 47. The inner side of the V-shaped plate 46 contacts the elastic metal sheet 45, causing the elastic metal sheet 45 to bend and contact both inner surfaces of the V-shaped plate 46. The elasticity ensures tight contact between the sliding block 47 and the inner side of the V-shaped plate 46. Multiple through holes are provided on the sliding block 47, and multiple threaded holes 48 are provided on the mounting bracket 41. Bolts 49 are threaded into the threaded holes 48. By aligning the through holes with the threaded holes 48, and then screwing the bolts 49 through the through holes and into the threaded holes 48, the position of the sliding block 47 is fixed. When the display rack is subjected to vibration, the vibration on the display plate is transmitted to the limiting rod 43. The vertical vibration of the limiting rod 43 is transmitted to the mounting plate 44, and the vibration on the mounting plate 44 is then transmitted to the elastic metal sheet 45. The elastic metal sheet 45 vibrates and further deforms, increasing the frictional resistance between the elastic metal sheet 45 and the inner side of the V-shaped plate 46. Simultaneously, friction is generated between the V-shaped plate 46 and the elastic metal sheet 45, rapidly dissipating the energy of the vibration, stabilizing the display plate, and protecting the displayed items.

[0023] Furthermore, the diameter of the through hole is larger than that of the threaded hole 48, allowing the bolt 49 to pass smoothly through the through hole and lowering the standard for alignment between the through hole and the threaded hole 48, making it easier to fix the sliding block 47. The diameter of the nut of the bolt 49 is larger than that of the through hole, allowing the bolt 49 to fix the sliding block 47.

[0024] It should be added that a brake plate is installed on the inner side of the V-shaped plate 46. When the elastic metal sheet 45 is attached to the brake plate, the frictional resistance between the brake plate and the elastic metal sheet 45 increases as the elastic force provided by the elastic metal sheet 45 increases, and the brake plate can provide a high coefficient of friction.

[0025] Working principle: By bending and deforming the elastic metal plate, the elastic metal sheet 45 is pressed tightly against the brake pad on the inner side of the V-shaped plate 46. When the device is vibrated, the vibration on the display plate is transmitted to the limiting rod 43. The vertical vibration of the limiting rod 43 is transmitted to the mounting plate 44, and the vibration on the mounting plate 44 is transmitted to the elastic metal sheet 45. The elastic metal sheet 45 is further deformed to buffer the vibration. At the same time, friction is generated between the elastic metal sheet 45 and the brake pad on the inner side of the V-shaped plate 46 to consume the energy generated by the vibration and quickly eliminate the vibration, thereby achieving the purpose of buffering the vibration and quickly eliminating the vibration to protect the display.
