Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically to a shelving unit that is easy to expand and adjust. Background Technology

[0002] The shelving used in the warehouse is all fixed and immovable. Loading and moving the shelving requires the joint work of a large number of people, which increases the consumption in the process.

[0003] According to patent document CN222248664U, a logistics storage rack that is easy to adjust includes two fixed plates. A first extension rack and a second extension rack are slidably fitted onto the two end surfaces of the two fixed plates, respectively. Each of the first and second extension racks has a fixing groove inside. A compression spring is fixedly connected to one side of the inner wall of the fixing groove, and a push plate is fixedly connected to one end of the compression spring. Both sides of the fixed plates are fixedly connected to the push plate. A fixing component is provided at the top of each of the first and second extension racks. An installation groove is provided on the inner surface of each of the first and second extension racks. A fixing rod is fixedly connected inside the installation groove. Multiple sliding sleeves are slidably fitted onto the surface of the fixing rod. A connecting component is provided on one side surface of each of the multiple sliding sleeves, and a telescopic plate is fixedly connected to one end of each connecting component.

[0004] Currently, traditional, easily expandable and adjustable shelving systems have limitations when storing goods and packages. When the vertical dimensions of the packages exceed the spacing between adjacent shelves, the packages cannot be placed neatly, resulting in poor versatility. Furthermore, since the shelf area is fixed and cannot be adjusted, packages placed on shelves that extend significantly beyond the front and rear edges of the shelf can become unstable, increasing the risk of the packages falling and getting damaged. Utility Model Content

[0005] The purpose of this utility model is to provide an easily expandable and adjustable shelf to solve the problem mentioned in the background art. In the process of placing goods and packages, when the vertical dimensions of the goods and packages exceed the spacing between adjacent shelves, the goods and packages cannot be placed neatly, resulting in poor versatility of logistics shelves. At the same time, since the surface area of ​​the shelves is fixed and cannot be adjusted, when the goods and packages placed on the shelves significantly exceed the front and rear edges of the shelf surface, the placement will be unstable, leading to the risk of the goods and packages falling and being damaged.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a column, wherein a locking block is provided on the inner side wall of the column, and an installation mechanism is provided on the inner wall of the column, wherein an expansion mechanism is detachably connected to the lower end of the installation mechanism;

[0007] The installation mechanism includes a horizontal frame, one side of which is engaged with one side of the column, and a support frame is provided on the other side of the horizontal frame. Sliding grooves are provided on both sides of the support frame, and slots are provided on both sides of the front end of the support frame. A support bracket is detachably connected to the inner side wall of the support frame. A shelf is movably connected to the upper end of the support bracket, and a nut is movably connected to the lower end of the shelf. A bolt is threaded onto the inner wall of the nut.

[0008] Preferably, one side of the horizontal frame is movably connected to one side of the support frame, and the support frame has sliding grooves on both sides.

[0009] Preferably, the upper end of the bolt passes through the bottom wall of the support frame and is connected to the nut via the support frame.

[0010] Preferably, one side of the card block is fixedly connected to the inner wall of the column, and the outer wall of the mounting mechanism is detachably connected to the inner wall of the column.

[0011] Preferably, the extension mechanism includes a sliding rod, the outer wall of which is slidably connected to the inner wall of the sliding groove, an inclined rod is provided on the outer wall of the sliding rod, an adjusting member is provided at the rear end of the sliding rod, a fixed rod is rotatably connected to one end of the inclined rod, and an extension plate is fixedly connected to one end of the fixed rod.

[0012] Preferably, the outer wall of the sliding rod is inserted into one end of the inclined rod, and the rear end of the sliding rod is threadedly connected to the front end of the adjusting member.

[0013] Preferably, the outer diameter of the sliding rod is adapted to the inner diameter of the sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The installation mechanism allows for flexible adjustment of shelf spacing and shelf area according to different specifications and placement requirements of goods. When adjusting the shelf spacing, simply engage the clips in the uprights using the slots. The movable connection between the shelves and the support frame ensures stability and prevents wobbling during adjustment. Furthermore, expanding the shelf area can be achieved by operating the expansion mechanism. The sliding rod moves within the sliding groove, moving the diagonal rod and the fixed rod, thus expanding or retracting the expansion panel to accommodate packages of different sizes. The adjustable mechanism allows users to quickly and easily adjust the position of the sliding rod, achieving precise control over the expansion panel's extent.

[0016] 2. The extension mechanism allows the equipment to more flexibly adapt to goods of different sizes and weights. Furthermore, when placing larger goods on the shelf, the sliding rod in the extension mechanism can be adjusted to slide forward or backward within the sliding groove, thereby moving the diagonal rod and fixed rod, which in turn pushes the extension plate to unfold, increasing the shelf area and ensuring stable placement of goods. Simultaneously, the adjustable mechanism allows users to precisely control the unfolding degree of the extension plate according to actual needs, meeting the placement requirements of goods of different sizes. In addition, the extension mechanism also allows the shelf to distribute the weight of heavier goods through the support of the extension plate, improving the shelf's load-bearing capacity and stability.
