Description

Technical Field

[0001] The invention relates to a mortise and tenon structure. Background Art

[0002] The mortise and tenon structure requires delicate and strong connections, and needs to be made by skilled craftsmen using special tools. It is difficult for ordinary people to make mortise and tenon joints that meet the precision requirements. Poor precision will cause the mortise and tenon structure to become skewed, loose, and swollen. Summary of the invention

[0003] The invention provides a prefabricated mortise and tenon component, and ordinary people can assemble various mortise and tenon structures by cutting the component.

[0004] Figure 1 The invention is a locking mortise and tenon structural member obtained by drilling holes and making mortises on a circular steel pipe, hereinafter referred to as the structural member, and the present invention is described by taking this as an example. The hole drilled on the structural member is called a mortise hole, the circular part of the mortise hole is matched with the outer diameter of the steel pipe, the mortise hole and the part of the circular steel pipe deformed by drilling the mortise hole are collectively called a mortise, and the circular steel pipe between the mortise and the mortise on the steel pipe that is not deformed is called a tenon.

[0005] Figure 2 It is a mortise and tenon structure formed by connecting the tenon of component one with the mortise of component two. The mortise on component one stuck in the left side of the mortise hole of component two acts as a tenon shoulder and forms the tenon of component one with the tenon head extending into the mortise hole of component two. Figure 2 It shows that the locking mortise and tenon structure uses the raw material between the mortise and the tenon on the structure as the tenon head, and forms the tenon of the structure with the tenon shoulder, so when the tenon is made on the round steel tube, the tenon is also formed on the round steel tube. For the convenience of the following, the positions of the tenons on the left and right sides of the mortise holes of the second structure on the first structure are named "tenon position" and "through position" respectively, and the tenons on the first structure and the second structure are called each other.

[0006] The first component can pass through the mortise hole of the second component as the mortise on it is rotated to the passing position in sequence. After passing into the position, the mortise of the first component is rotated to the tenon position and stuck on the mortise hole through which it passes to act as a tenon shoulder and form a tenon with the tenon head inserted into the mortise hole of the second component. It can then be connected with the mortise of the second component to form a mortise and tenon structure. Therefore, this component can be intercepted to assemble various mortise and tenon structures.

[0007] Figure 3 It is a mortise and tenon ring, which is elastic and can slide on the member as the member deforms elastically, thus pushing the Figure 2 The mortise ring 3 on the member 1 slides to the Figure 4 In the position shown, the mortise ring 3 is buckled on the mortise of the second component. Figure 7 It is an articulated lever. Figure 5 As shown in the figure, extend into the two ends of the mortise ring 3, and then move along the arrow to Figure 6The position shown in the figure, during this process, the hinged lever 4 hinges the two ends of the mortise ring 3 that are clasped on the mortise of the second member together. The two ends of the mortise ring 3 are elastically stretched during the process of being hinged together, and the generated tension tightens the mortise of the second member on the tenon of the first member. At the same time, the mortise ring 3 also blocks the mortise hole of the second member and squeezes the tenon shoulder of the first member, preventing the tenon of the first member from moving axially in the mortise of the second member.

[0008] After the hinged mortise ring 3 is hinged, the C-shaped ring on the hinged lever 4 is Figure 6 As shown, it is fixed on the tenon of member 1 by elastic clip. Remove the hinged lever 4 clipped on member 1 to release the mortise and tenon ring 3 and disassemble the mortise and tenon structure.

[0009] The present invention prevents the tenon from axially moving in the mortise by "locking" the tenon on the tenon and "locking" the tenon hole, so it is named "locking tenon and tenon structure".

[0010] Its advantages are as follows:

[0011] 1. Ordinary people can assemble various mortise and tenon structures by cutting this material, such as shelves, fences, tables, stools, wall cabinets, closets, stoves, etc. It can also be used to assemble building formwork brackets, making the mortise and tenon structure with delicate and firm connection more convenient to use.

[0012] 2. The manufactured mortise and tenon structure can be easily disassembled and assembled repeatedly.

[0013] 3. No material is removed when making mortise and tenon joints, so the weakening of material strength is less than that of traditional mortise and tenon joints.

[0014] 4. After the mortise and tenon are made, the tenon is formed on the structural member.

[0015] 5. The materials used to make the components include but are not limited to steel pipes, which expands the application field of mortise and tenon structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The mortise holes are made using a stamping process, which consists of two steps: cutting and extrusion.

[0025] The cutting die is pushed toward the steel pipe axis from both the upper and lower directions along the upper and lower generatrixes symmetrical to the steel pipe axis, so that the blades of the upper and lower cutting dies meet at the steel pipe axis. In this process, the cutting die first squeezes the steel pipe into shape, and then cuts the steel pipe into two symmetrical parts at the steel pipe axis. The cross-sectional shapes of the two symmetrical parts are the same. Figure 1 After the cut is completed, the cut is sent to the mortise forming station, and the mortise forming die also uses the method of pushing into the cut from both the upper and lower directions toward the axis of the steel pipe to make the cut expand radially and shorten axially, squeezing the cut into Figure 1 The reason why the mold is pushed up and down toward the axis of the steel pipe at the same time is to make the seam of the inward flange after the mortise is formed. Figure 2 As shown in the AA section view, in the middle of the inner side of the mortise.

[0026] The mortise ring is bent into shape using 8# steel wire and then welded at both ends, then quenched and tempered at medium temperature; the articulated lever is bent into shape using φ6 steel wire and then flame quenched or normalized.
