Description
Technical Field
[0001] This utility model relates to the field of shelving technology, and in particular to a shelving unit with inter-layer lifting device. Background Technology
[0002] Shelving is a type of rack used to store goods. It plays an important role in warehousing and commerce. It is made of different materials, such as steel and wood, and has various structures, including light, medium and heavy-duty. Shelving can make full use of space, arrange goods in layers and categories, make warehouses or stores more tidy and orderly, and facilitate the management and inventory of goods.
[0003] Existing technologies, such as the utility model with publication number CN204363359U, relate to the field of shelving, specifically a type of shelving that solves the problems of non-adjustable shelf spacing and inconvenient shelving assembly and disassembly. The key technical point is that a shelving unit includes several support frames, each support frame including a fixed rod. Each fixed rod has a stamped forming part distributed along the length of the fixed rod, and the forming part protrudes from the surface of the fixed rod to form a snap-fit groove. Adjacent support frames are fixedly connected by a connecting rod, and the connecting rod has a stamped opening for the forming part to be inserted into. A snap-fit block is provided in the opening to engage with the snap-fit groove, and the opening and snap-fit block are distributed along the length of the connecting rod. The advantage of this utility model is that the shelf spacing is adjustable through the cooperation of the snap-fit block and the fixed groove, greatly improving the utilization rate of the shelving unit, and it is convenient to install and disassemble. However, the spacing between the shelving units is fixed, making it difficult to flexibly adjust according to the height of the goods, affecting the normal use of the equipment.
[0004] To address the issue of uniform spacing between shelves and racks, making it difficult to flexibly adjust according to the height of goods and affecting the normal use of the equipment, the existing technology involves purchasing shelves of different heights. However, this increases the user's financial expenditure and leads to inconvenience in using the equipment. Utility Model Content
[0005] The purpose of this utility model is to solve the shortcomings of existing technology, such as the single spacing between shelves and racks, which makes it difficult to flexibly adjust according to the height of goods and affects the normal use of equipment. Therefore, this utility model proposes a shelf with an inter-layer lifting device.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a shelf with an inter-layer lifting device, comprising a steel frame and an adjusting device. Shelves are provided on the surface of the steel frame, and the adjusting device is disposed on the surface of the steel frame. The adjusting device includes a motor, which is fixedly connected to the steel frame. The drive end of the motor passes through the steel frame and is fixedly connected to a threaded rod. A retainer is fixedly connected to one side of the shelf, and a threaded hole is formed on the surface of the retainer. The threaded rod is threadedly connected to the retainer. A sliding groove is formed on the inner wall of the steel frame. By setting the adjusting device, the spacing between the shelves can be easily adjusted, facilitating the storage of goods of different heights, increasing the flexibility of the equipment, and reducing the mismatch between goods and shelves.
[0007] Preferably, a rotating rod is fixedly connected to one side of the shelf, and a movable wheel is rotatably connected to the surface of the rotating rod. By setting the movable wheel, it is easy to move the shelf, which increases the ease of use of the equipment, reduces the difficulty of operation, and improves the safety of the equipment.
[0008] Preferably, there are two movable wheels, which are arranged in a mirror-symmetric manner. By setting the movable wheels, it is easier to move the auxiliary shelf, which increases the stability of the equipment, reduces the difficulty of operation, and makes it convenient to use.
[0009] Preferably, the movable wheel is installed in the groove of the inner wall of the steel frame, and a pad is fixedly connected to the side of the threaded rod away from the motor. By setting the motor, it is easy for the motor to cooperate with the threaded rod to drive the shelf to move during use, which increases the ease of use of the equipment and reduces the difficulty in adjusting the spacing of the shelves.
[0010] Preferably, the surface of the shelf is provided with a stabilizing device, which includes a fixing sleeve that is fixedly connected to the shelf. The surface of the fixing sleeve is threaded, and a lead rod is threadedly connected to the inner wall of the fixing sleeve. By setting up the stabilizing device, it is easy to restrict the goods, reduce the possibility of the goods falling, and increase the safety of the equipment.
[0011] Preferably, a knob is fixedly connected to the lower surface of the lead screw. There are four lead screws arranged in a mirror-symmetrical manner. By setting the lead screws, it is easy to restrict the goods during use, which increases the ease of use of the equipment and reduces the difficulty of operating the equipment.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, by setting an adjustment device and a stabilizing device, when it is necessary to adjust the spacing of the shelves, the motor is started, the motor drives the threaded rod, and the threaded rod rotates while cooperating with the clamp to drive the shelf to move downward. At this time, the moving wheel cooperates with the shelf to move. When the goods are placed on the shelf, the knob is turned, the knob drives the screw to rise and abut against the goods, reducing the risk of the goods falling. By setting this invention, it is easy to adjust the spacing between the shelves, which is convenient for the equipment to store goods of different heights, increases the flexibility of the equipment, and reduces the situation of goods not matching the shelves.
