Description

Technical Field

[0001] This utility model belongs to the field of assembled wooden frame technology, and particularly relates to a three-sided assembled wooden frame. Background Technology

[0002] In furniture manufacturing, decoration projects, and handicrafts, triangular wooden frames are widely used due to their structural stability and excellent load-bearing capacity. Currently, the forming of traditional triangular wooden frames generally relies on two methods: screw fastening or glue bonding. When using screws, the loose texture of the wood can easily lead to stripping, reducing the connection strength of the wooden frame and even causing structural loosening. While glue bonding is simple to operate, the overall connection strength is limited. Under high temperature and high humidity environments, the glue is prone to aging and delamination, causing the wooden frame to fall apart. In addition, both methods lack a quick and convenient assembly design, which not only increases production and installation time and costs but also hinders product transportation and repeated disassembly and reassembly.

[0003] Therefore, it is essential to invent a three-sided assembled wooden frame. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a three-sided assembled wooden frame, including an assembly support, an outer wedge groove, an inner wedge groove, a pin hole, a positioning wedge, a reinforcing wedge, an inner corner block, and a wooden pin. The assembly support is provided in three parts, and each assembly support has an outer wedge groove, an inner wedge groove, and a pin hole at both ends. Each positioning wedge is tenoned in two of the outer wedge grooves, and each wooden pin is wedged into the pin hole of the assembly support. The two reinforcing wedges provided on the inner corner block are tenoned in the inner wedge grooves of the corresponding assembly supports.

[0005] Preferably, the two ends of the three assembled supports have the same slope angle, the interior angle between two of the assembled supports is 60 degrees, and the three assembled supports together construct an equilateral triangle structure.

[0006] Preferably, after the inclined surfaces of the two assembled supports come into contact with each other, their outer wedge grooves form a wedge groove body that matches the positioning wedge block. The positioning wedge block has a funnel-shaped structure, and a through hole concentric with the pin hole of the assembled support is opened through the center of the positioning wedge block.

[0007] Preferably, three wooden pins are provided. Each wooden pin is sequentially wedged into the pin hole of one of the assembly supports, the through hole of the positioning wedge, and the pin hole of the other assembly support, and the positioning wedge and the two assembly supports are fixed together with mortise and tenon joints.

[0008] Preferably, the outer wedge groove and the inner wedge groove have the same shape, the inner wedge groove is located inside the outer wedge groove, the inner wedge groove is an equilateral trapezoidal groove, and the reinforcing wedges of the inner corner blocks are respectively wedgeed into the inner wedge grooves of the adjacent assembly supports.

[0009] Preferably, the inner corner block has a triangular structure, with each inner corner block located at the inner corner of the two assembly supports, and the inner surface of the assembly support in close contact with the hypotenuse of the inner corner block.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model achieves rapid mortise and tenon splicing of a three-sided wooden frame through the combination design of outer wedge groove, inner wedge groove, positioning wedge block and wooden dowel, without the need for screw fastening or glue bonding, which significantly improves installation efficiency, reduces labor costs, and facilitates transportation and repeated disassembly and assembly, meeting the needs of modular use.

[0012] The funnel-shaped structure of the positioning wedge block of this utility model forms a tight wedge with the outer wedge groove, and the wooden pin passes through to lock it. Together with the inner corner block to reinforce the inner corner of the assembly support, the wooden frame forms multi-dimensional force support at each splicing point. Compared with the traditional connection method, it significantly improves the structural stability and effectively avoids the problems of loosening and falling apart.

[0013] Furthermore, this invention eliminates the reliance on glue for fixing, avoids the impact of high temperature and high humidity on the connection strength, and allows the wooden mortise and tenon structure to be partially repaired by replacing positioning wedges, wooden dowels, and other components, thus extending the service life of the wooden frame and combining environmental protection and economy.

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides a three-sided assembled wooden frame, including an assembly support 1, an outer wedge groove 2, an inner wedge groove 3, a pin hole 4, a positioning wedge 5, an inner corner block 6, a reinforcing wedge 7, and a wooden pin 8. The assembly support 1 is provided in three parts, and each assembly support 1 has an outer wedge groove 2, an inner wedge groove 3, and a pin hole 4 at both ends. Each positioning wedge 5 is tenoned in two of the outer wedge grooves 2, and each wooden pin 8 is wedged into the pin hole 4 of the assembly support 1. The two reinforcing wedges 7 provided on the inner corner block 6 are tenoned in the corresponding inner wedge grooves 3 of the assembly support 1.

[0023] Furthermore, all three assembly supports 1 are made of solid wood, with both ends cut into bevels at the same angle. The interior angle formed by splicing any two assembly supports 1 is 60 degrees, thus constructing a standard equilateral triangle frame. The bevel cutting precision is controlled within ±0.5 degrees to ensure accurate angles after splicing, meeting the geometric requirements of an equilateral triangle structure.

[0024] Furthermore, after the inclined surfaces of the two assembly supports 1 are joined together, their outer wedge grooves 2 combine to form a wedge groove body that fits the funnel-shaped positioning wedge block 5. The positioning wedge block 5 is made of high-strength engineering plastic or hardwood, and its central through hole is concentric with the pin hole 4 on the assembly support 1. When the positioning wedge block 5 is embedded in the wedge groove body, its funnel-shaped conical surface fits tightly against the inner wall of the outer wedge groove 2, providing circumferential positioning and anti-detachment effects.

[0025] Furthermore, the three wooden dowels 8 are made of cylindrical hardwood, with diameters matching the dowel holes 4 and the through holes of the positioning wedges 5. During installation, the wooden dowels 8 pass sequentially through the dowel holes 4 of one assembly support 1, the through holes of the positioning wedges 5, and the dowel holes 4 of another assembly support 1, achieving mortise and tenon fixation through interference fit. The surface of the wooden dowels 8 has anti-slip textures to enhance the tightening force after wedging and prevent loosening and falling off.

[0026] Furthermore, both the outer wedge groove 2 and the inner wedge groove 3 are equilateral trapezoidal grooves, with the inner wedge groove 3 located inside the outer wedge groove 2. The shapes of the two ends of the reinforcing wedge block 7 match those of the inner wedge groove 3, and it is made of solid wood of the same material as the assembly support 1. When the two assembly supports 1 are spliced, the reinforcing wedge block 7 is wedged into the corresponding inner wedge groove 3, and the wedge-shaped self-locking characteristic of the trapezoidal groove further enhances the stability and pull-out resistance of the splice.

[0027] Furthermore, the inner corner block 6 is an equilateral triangle structure made of solid wood, with its hypotenuse angle matching the inner angle of the assembly support 1. Each inner corner block 6 is embedded in the inner corner of two assembly supports 1, with the inner surface of the assembly support 1 in close contact with the hypotenuse surface of the inner corner block 6, forming a surface contact support. The inner corner block 6 cooperates with the reinforcing wedge block 7 to reinforce the joint from both the inside and outside, effectively dispersing the stress at the inner corner and improving the overall structural strength.

[0028] The working principle is as follows: First, three solid wood assembly supports 1 with inclined surfaces are joined together in pairs to form a 60-degree interior angle, constituting an equilateral triangular frame foundation. At this time, the outer wedge grooves 2 of adjacent assembly supports 1 combine to form a wedge groove body, which is adapted to the funnel-shaped positioning wedge block 5. After the positioning wedge block 5 is embedded, its conical surface fits against the inner wall of the outer wedge groove 2, completing the circumferential positioning.

[0029] Next, the cylindrical wooden dowel 8 passes through the dowel hole 4 of the assembly support 1 and the through hole of the positioning wedge 5 in sequence, and the three are fixed together by interference fit to prevent the positioning wedge 5 from coming out, thus realizing the initial connection between the assembly supports 1.

[0030] Then, the two ends of the reinforcing wedge 7 are embedded in the inner wedge grooves 3 of the adjacent assembly support 1. With the help of the wedge-shaped self-locking characteristics of the equilateral trapezoidal groove, the stability and pull-out resistance of the splice are enhanced from the inside.

[0031] Finally, the inner corner block 6 of the equilateral triangle structure is embedded in the inner corner of the assembly support 1, and its hypotenuse is in close contact with the inner surface of the assembly support 1. Together with the reinforcing wedge block 7, it disperses the inner corner stress from both the inner and outer sides, further improving the overall strength and stability of the three-sided assembled wooden frame.

[0032] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
