[0023] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0024] According to Figure 1 、 2 As shown in Figures 3, 4, and 5, a combined wooden frame is proposed in this embodiment, which includes a vertical frame 2 and a plurality of rectangular frames 1 arranged on the vertical frame 2. The vertical frame 2 includes four columns 21;

[0025] The four columns 21 are fixed at the four corners of the rectangular frame 1 for supporting the rectangular frame 1. Each rectangular frame 1 is arranged in an up-and-down order, and the adjacent upper and lower rectangular frames 1 form a cell for storing items.

[0026] Regarding the rectangular frame 1:

[0027] The rectangular frame 1 includes two relatively arranged first frame plates 11 and two relatively arranged second frame plates 12. The two ends of the first frame plate 11 are provided with first inclined surfaces, and the two ends of the second frame plate 12 are provided with second inclined surfaces. The first inclined surface is attached to the second inclined surface, and a mortise and tenon structure A is provided at the joint of the first inclined surface and the second inclined surface;

[0028] The rectangular frame 1 is composed of two first frame plates 11 and two second frame plates 12. The adjacent first frame plate 11 and second frame plate 12 are fixed through the mortise and tenon structure A. While ensuring the structural strength at the joint of the first frame plate 11 and the second frame plate 12, this connection structure can effectively increase the use length of the wood, reduce the dependence on large-sized logs, improve the wood utilization rate, and reduce waste.

[0029] A 90-degree angle is formed between the first frame plate 11 and the second frame plate 12. A slot 13 is provided at the joint where the first frame plate 11 and the second frame plate 12 are in contact. The column 21 passes through the slot 13 and is detachably connected to the first frame plate 11 and the second frame plate 12 through a bolt positioning member.

[0030] The rectangular frame 1 composed of the first frame plate 11 and the second frame plate 12 is fixed to the column 21 through a bolt positioning member. The detachable connection method facilitates the operator to replace the problematic rectangular frame 1 separately, reducing the maintenance cost.

[0031] For the specific content of the mortise and tenon structure A, please refer to the following description.

[0032] The mortise and tenon structure A includes a first convex block 16 and a third card slot 17. The first convex block 16 is placed on the first inclined surface. The first convex block 16 is fixedly connected to both ends of the first frame plate 11. The third card slot 17 is provided on the second inclined surface. The first convex block 16 is engaged with the third card slot 17.

[0033] Between the first frame plate 11 and the second frame plate 12, the assembly method of the mortise and tenon structure A is as follows:

[0034] Align the first frame plate 11 with the second frame plate 12. The first convex blocks 16 at both ends of the first frame plate 11 will be stuck into the third card slots 17 provided at both ends of the second frame plate 12. These convex and concave parts are closely fitted together, and then glued to enhance the connection strength, thus forming a continuous and flat frame.

[0035] It should be noted that the cross-section of the first convex block 16 is trapezoidal, and the third card slot 17 is a trapezoidal slot matching the first convex block 16. In this way, a dovetail joint structure is formed between the first convex block 16 and the third card slot 17. Due to the extrusion between the inclined surfaces on both sides of the first convex block 16, the joint between the first frame plate 11 and the second frame plate 12 can withstand forces from different directions of the rectangular frame 1, making the overall structure of the rectangular frame 1 more stable.

[0036] Regarding the bolt positioning member:

[0037] The bolt positioning member includes a plurality of pin holes 18. The pin holes 18 are provided on one side of the two first frame plates 11 facing each other and on the side of the two second frame plates 12 away from each other. Each pin hole 18 communicates with each slot 13 respectively. A positioning pin 19 is assembled in the pin hole 18. The positioning pin 19 penetrates into the slot 13 and is threadedly connected to the positioning hole 22 provided on the outer side of the column 21.

[0038] The fixing method of the bolt positioning member is as follows:

[0039] When installing the rectangular frame 1 on the column 21, the column 21 passes through the slot 13 opened at the connection between the first frame plate 11 and the second frame plate 12. Adjust the positions of the first frame plate 11 and the second frame plate 12 so that a certain positioning hole 22 on the outer side of the second frame plate 12 is in a corresponding state with the pin holes 18 on the outer sides of the first frame plate 11 and the second frame plate 12. Then, insert the positioning pin 19 through them, and the fixation between the rectangular frame 1 and the column 21 can be completed.

[0040] In a relatively good implementation manner, four triangular ribs 3 are provided inside the rectangular frame 1. The triangular ribs 3 are placed at the included angle between the first frame plate 11 and the second frame plate 12. The triangular ribs 3 are detachably connected to the first frame plate 11 and the second frame plate 12 through the mortise and tenon structure B. The triangular ribs 3 arranged at the included angle between the first frame plate 11 and the second frame plate 12 are fixed to the first frame plate 11 and the second frame plate 12 through the mortise and tenon structure B, which can play the role of a reinforcing rib and be used to further strengthen the structure at the connection of the first frame plate 11 and the second frame plate 12.

[0041] It is worth further supplementing that the mortise and tenon structure B includes a second convex block 31 and a third convex block 32. The second convex block 31 is fixedly connected to the side of the triangular rib 3 facing the first frame plate 11, and the third convex block 32 is fixedly connected to the side of the triangular rib 3 facing the second frame plate 12. The second convex block 31 is engaged with the first card slot 14 opened on the outer side of the first frame plate 11, and the third convex block 32 is engaged with the second card slot 15 opened on the outer side of the second frame plate 12. The installation method of the mortise and tenon structure B is the same as that of the mortise and tenon structure A, and no more detailed description will be given here.

[0042] It should be noted that the cross-sections of the second convex block 31 and the third convex block 32 are both trapezoidal, and the first card slot 14 and the second card slot 15 are both trapezoidal grooves that match the second convex block 31 and the third convex block 32. Similarly, the first card slot 14 and the second card slot 15 are also designed as dovetail tenon structures to strengthen the structural strength of the connection parts between the triangular rib 3 and the first frame plate 11 and the second frame plate 12, and no more detailed description will be given here.

[0043] The working principle of this application:

[0044] Four columns 21 are fixed at the four corners of the rectangular frame 1 to support the rectangular frame 1. Each rectangular frame 1 is arranged in an up-and-down order, and the adjacent upper and lower rectangular frames 1 form cells for storing items.

[0045] The rectangular frame 1 is composed of two first frame plates 11 and two second frame plates 12. The adjacent first frame plate 11 and the second frame plate 12 are fixed through the mortise and tenon structure A. The rectangular frame 1 composed of the first frame plate 11 and the second frame plate 12 is fixed to the column 21 through a bolt positioning member. The detachable connection method facilitates the operator to replace the problematic rectangular frame 1 alone and reduces the maintenance cost.
