Description

Technical Field

[0001] This utility model relates to the field of LED digital display technology, and in particular to a shelf with adjustable height and distance. Background Technology

[0002] LED digital display is a digital display technology that uses light-emitting diodes as a light source. It is widely used in the display of digital information in electronic devices, from small indoor instruments to large outdoor displays. According to the packaging form, it can be divided into two types: common anode and common cathode. In actual use, it needs to be used with corresponding driving circuits to achieve stable and clear digital display.

[0003] A shelving unit is a multifunctional storage structure integrating LED digital display functionality. It not only serves the traditional storage function of a shelving unit but also displays real-time information such as time, temperature, and humidity via its LED digital display module. However, the position of the shelving unit often needs to be adjusted. With technological advancements, the adjustment mechanism is the core component enabling its flexible use. It is mainly used to adjust shelf height, display angle, or overall structural shape. Common adjustment methods include snap-on, knob, and sliding rail types. Snap-on types quickly fix shelf positions using pre-set slots and protrusions, suitable for frequent adjustments. Knob types achieve precise height adjustment using a threaded structure, offering greater stability. However, this type of adjustment mechanism is relatively complex in design and cumbersome to operate, hindering quick and convenient adjustments. Furthermore, it cannot flexibly adjust the distance between shelves, which to some extent limits its efficiency and applicability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a shelf with adjustable height and distance, aiming to improve the problems of the existing technology where the adjustment mechanism is relatively cumbersome, cannot be adjusted quickly, and cannot adjust the distance of the baffle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable shelf with adjustable height and distance, including a support column, an adjustment mechanism on the inner side of the support column, the adjustment mechanism being suitable for adjusting the distance and height of the shelf, and a vibration damping mechanism at the bottom of the support column for vibration reduction;

[0006] The adjustment mechanism includes an adjustment plate, the inner side of which is fixedly connected to the outer side of the support column. The adjustment plate has an elongated groove inside, and a threaded rod is slidably connected to the inner wall of the groove. A knob is fixedly connected to the outer wall of the threaded rod, and a fixing plate is threadedly connected to the outer wall of the threaded rod. A slot assembly is provided on the front side of the fixing plate.

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

[0008] The vibration damping mechanism includes a connecting plate, the top of which is fixedly connected to the bottom of a support column. A circular hole is provided at the bottom of the connecting plate, and a connecting rod is slidably connected to the inner wall of the circular hole. A second baffle is fixedly connected to the outer wall of the connecting rod, and a threaded column is fixedly connected to the bottom of the second baffle. A spring is provided on the outer wall of the threaded column, and a base assembly is provided on the outer wall of the threaded column.

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

[0010] The card slot assembly includes a card plate, the rear side of which is fixedly connected to the front side of a fixing plate. A long card slot is provided on the front side of the card plate, and a storage component is provided on the inner wall of the long card slot.

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

[0012] The storage assembly includes a baffle, the rear side of which is slidably connected to the inner wall of the elongated slot, and the front side of the baffle has multiple serrated holes.

[0013] As a further description of the above technical solution:

[0014] The base assembly includes a conical base, the inner wall of which is slidably connected to the outer wall of a threaded column, and a nut is threadedly connected to the outer wall of the threaded column.

[0015] As a further description of the above technical solution:

[0016] The front side of each support column is provided with multiple support holes, and the inner wall of each support hole is slidably connected to the side of the baffle.

[0017] As a further description of the above technical solution:

[0018] The upper and lower ends of the support column are provided with multiple trapezoidal support blocks, which are used to fix the shelf.

[0019] As a further description of the above technical solution:

[0020] The outer side of the support column is provided with a connecting strip, and the rear side of the connecting strip is fixedly connected to the front side of the adjustment plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the knob is turned, the knob drives the threaded rod away from the fixed plate. At this time, the threaded rod can slide inside the long groove on the adjustment plate. When the adjustment is made to a suitable position, the knob is turned back. The knob will drive the threaded rod back into the fixed plate. The knob and the fixed plate will lock the adjustment plate again. Then, the baffle is inserted into the long groove. At the same time, the side of the baffle will be locked into the support hole, realizing the ability to freely adjust the distance and height of the baffle according to the actual use.

[0023] 2. In this utility model, during installation, the connecting plate is first installed on the support column, and then the connecting rod is installed along the circular hole in the connecting plate. Subsequently, the conical base and nut are installed on the threaded column at the bottom of the connecting rod. When vibration occurs, the vibration is transmitted to the conical base, and then to the spring through the conical base. At this time, the spring will stretch and contract to buffer the vibration. At the same time, the baffle plate will automatically adjust along the outer wall of the connecting rod to keep the whole in balance, thus achieving the function of supporting the whole and reducing vibration.
