Description

Technical Field

[0001] This utility model relates to a limiting plate and a shelf, specifically to a limiting plate with a limiting track and a foldable shelf. Background Technology

[0002] A storage rack is a shelf used to hold utensils, supporting them to a certain height for easy access. However, the large size of storage racks causes significant inconvenience during transportation and when not in use, especially with the rapid development of e-commerce in the last decade, increasing the need for smaller racks for transport. Therefore, providing a foldable storage rack is essential.

[0003] Existing technology, such as Chinese utility model patent CN202420711598.4, describes a multi-directional folding storage rack, which includes several rotating structures. Each rotating structure includes two symmetrically arranged cross-support members, each cross-support member comprising two rotating rods hinged together at their midpoints. Connecting rods are provided between corresponding ends of the rotating rods of two different cross-support members within the same rotating structure. The ends of two adjacent rotating rods in adjacent rotating structures are hinged together. A support plate is also included, with slots on two parallel edges below the support plate, corresponding to the connecting rods. It is evident that this structure employs a vertical folding method, resulting in a relatively complex structure. Furthermore, this structure is prone to instability in the support frame. Utility Model Content

[0004] This invention overcomes the above-mentioned defects by providing a foldable storage rack with a limiting track and limiting plate. This foldable storage rack with a limiting track and limiting plate has a foldable function, effectively reducing its volume during transportation and storage.

[0005] The technical solution of this utility model is as follows.

[0006] A limiting plate with a limiting track is provided. The main body of the limiting plate is a sheet-like structure with three convex structures. A central fixing hole is provided at the center of the main body of the limiting plate. One of the convex structures has 1 to 3 bracket fixing holes. The other two convex structures have limiting track openings and bracket fixing holes.

[0007] More preferably, the opening of the limiting track is arc-shaped.

[0008] A foldable shelf using the aforementioned limiting rail and limiting plate includes a movable bracket, a fixed bracket, a connecting rod, and a limiting rail and limiting plate; the connecting rod is fixedly connected to the fixed bracket, and the two ends of the connecting rod are respectively fixed with limiting rails and limiting plates; the movable bracket is connected to the limiting rail opening of the limiting rail and limiting plate by screws.

[0009] More preferably, the number of movable supports is two; the number of fixed supports is one.

[0010] More preferably, the connecting rod and the fixed bracket are fixedly connected by fixing screws.

[0011] More preferably, the screw is a wing screw.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] The present invention incorporates a design with a limiting track and limiting plate, which enables the storage rack connected to the limiting track and limiting plate to have a foldable function, effectively reducing its volume during transportation and storage, and facilitating storage and transportation.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Example 1

[0021] like Figure 1As shown, this embodiment provides a limiting plate with a limiting track. The limiting plate body 1.1 of the limiting plate 1 is a sheet-like structure with three convex structures. A central fixing hole 1.2 is provided at the center of the limiting plate body 1.1; two bracket fixing holes 1.3 are provided on one of the convex structures; and the other two convex structures each have a limiting track opening 1.4 and one bracket fixing hole 1.3. In this embodiment, the limiting track opening 1.4 is arc-shaped.

[0022] Example 2

[0023] like Figures 2-4 As shown, this embodiment provides a foldable storage rack with a limiting track and limiting plate, including two movable supports 2.1, one fixed support 2.2, a connecting rod 3, and a limiting track and limiting plate 1; the connecting rod 3 and the fixed support 2.2 are fixedly connected by fixing screws 4; specifically, as shown... Figure 2 and Figure 3 As shown, the two ends of the connecting rod 3 are respectively fixed with limiting plates 1 with limiting tracks between them and the fixed bracket 2.2, that is, a foldable shelf contains two limiting plates 1 with limiting tracks; the movable bracket 2.1 is connected to the limiting track opening 1.4 of the limiting track 1 with limiting track by a wing screw 5. When the wing screw 5 is not tightened, the two movable brackets 2.1 can move in the arc-shaped limiting track opening 1.4 through the wing screw 5.

[0024] It should be noted that the central fixing hole 1.2 is the fixing screw 4 that passes through the connecting rod 3 and the fixing bracket 2.2, as shown. Figure 4 The fixing screw 4 is used in the middle. During use, the two bracket fixing holes 1.3 on one of the convex structures of the limiting plate 1 with the limiting track are fixed to the fixed bracket 2.2 by the fixing screw 4. This is to make the fixed bracket 2.2 more secure with the limiting plate 1 with the limiting track. Two movable brackets 2.1 are connected to the limiting track opening 1.4 of the limiting plate 1 with the limiting track by wing screws 5. Because the limiting track opening 1.4 is arc-shaped, the two movable brackets can rotate relative to the fixed bracket 2.2, thus achieving a foldable function. If needed, pull the two movable brackets along the limiting track opening 1.4 to the end, tighten the wing screws 5 connected to the limiting track opening 1.4, and then connect the wing screws 5 to the bracket fixing holes 1.3 next to the limiting track opening 1.4 to fix the limiting plate 1 with the limiting track to the movable brackets 2.1, thus achieving a non-folded state, such as... Figure 2 As shown. To fold it up, remove the wing screw 5 inside the bracket fixing hole 1.3 next to the limit track opening 1.4, and then loosen the wing screw 5 on the limit track opening 1.4, so that the two movable brackets are pulled along the limit track opening 1.4 to the other end, thus folding it up. The folded version is as shown. Figure 4 As shown.

[0025] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
