Technical Field

[0001] The invention belongs to the field of mortise and tenon joint reinforcement, in particular to a mortise and tenon joint reinforcement device which is convenient for assembly and disassembly. Background Art

[0002] The mortise and tenon joint is a unique connection method in traditional Chinese wooden structures. It does not use modern connection materials such as nails or glue, but relies on the shape and size of the wooden components themselves for precise matching and connection. Specifically, the mortise and tenon joint consists of two parts: the tenon and the mortise. The tenon refers to the protruding part of the wooden component, usually in the shape of a tenon head; while the mortise refers to the recessed part reserved on the wooden component, usually in the shape of a mortise eye or mortise mouth. When connecting, the tenon is inserted into the mortise eye, and a firm connection between the wooden components is achieved through precise matching and friction.

[0003] The traditional simple mortise and tenon connection method may have problems such as loose connection and easy loosening, which affects the stability and safety of the overall structure. Summary of the invention

[0011] The first trapezoidal clamping block is slidably embedded in the first trapezoidal slide groove, and the second trapezoidal clamping block is slidably embedded in the second trapezoidal slide groove.

[0012] Preferably, when the L-shaped reinforcement frame limit card is embedded in the connecting frame 1 and the connecting frame 2, the L-shaped reinforcement frame and the connecting frame 1 and the connecting frame 2 are flush with each other.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown:

[0028] Embodiment 1: The present invention provides a mortise and tenon joint reinforcement device that is convenient for assembly and disassembly, comprising a first connecting frame mechanism 1, a second connecting frame mechanism 2, a reinforcement mechanism 3 and a positioning cylinder 4:

[0029] The first connecting frame mechanism 1 comprises a connecting frame 11, and a trapezoidal groove 12 is formed at one end of the connecting frame 11;

[0030] The second connecting frame mechanism 2 includes a second connecting frame 21, one end of which is fixedly connected to a trapezoidal wedge 22;

[0031] The trapezoidal wedge 22 is limitedly slidably embedded in the trapezoidal groove 12 , the reinforcement mechanism 3 is limitedly slidably embedded in the first connecting frame mechanism 1 and the second connecting frame mechanism 2 , and the positioning cylinder 4 penetrates the second connecting frame mechanism 2 and is embedded in the reinforcement mechanism 3 .

[0032] As can be seen from the above, when in use, the trapezoidal wedge 22 on the connecting frame 21 of the second connecting frame mechanism 2 is aligned downward with the trapezoidal groove 12 and pushed in to achieve a preliminary mortise and tenon connection;

[0033] Then, the reinforcing mechanism 3 is limitedly slidably embedded into the connected first connecting frame mechanism 1 and the second connecting frame mechanism 2 to further enhance the stability of the connection;

[0034] Finally, the whole device is assembled by passing the positioning cylinder 4 through the second connecting frame mechanism 2 and snapping it onto the reinforcing mechanism 3, ensuring that the connection is both firm and easy to disassemble and maintain.

[0035] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a trapezoidal slide groove 13 is further provided on the connecting frame 11, and a trapezoidal slide groove 23 is further provided on the connecting frame 21;

[0036] The reinforcement mechanism 3 includes an L-shaped reinforcement frame 31, one end of the L-shaped reinforcement frame 31 is fixedly connected to a trapezoidal block 1 32, and the other end of the L-shaped reinforcement frame 31 is fixedly connected to a trapezoidal block 2 33;

[0037] The trapezoidal clamping block 1 32 is slidably embedded in the trapezoidal slide groove 13 , and the trapezoidal clamping block 2 33 is slidably embedded in the trapezoidal slide groove 23 .

[0038] Specifically, when the L-shaped reinforcement frame 31 is limitedly embedded in the first connecting frame 11 and the second connecting frame 21 , the L-shaped reinforcement frame 31 and the first connecting frame 11 and the second connecting frame 21 are flush with each other.

[0039] As can be seen from the above, the L-shaped reinforcement frame 31 of the reinforcement mechanism 3 is aligned so that the trapezoidal block 1 32 at one end thereof is slidably inserted into the trapezoidal slide groove 1 13, and the trapezoidal block 2 33 at the other end thereof is slidably inserted into the trapezoidal slide groove 2 23. In this way, the L-shaped reinforcement frame 31 is not only limitedly inserted into the connection frame 1 11 and the connection frame 2 21, but also flush with them, thereby ensuring the stability of the connection and the overall aesthetics.

[0040] Finally, the positioning cylinder 4 is passed through the second connecting frame mechanism 2 and is snapped onto the reinforcing mechanism 3 to complete the assembly of the entire device.

[0041] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that a first positioning hole 24 is further provided through the second connection frame 21, and a second positioning hole 34 is further provided on the L-shaped reinforcement frame 31;

[0042] When the L-shaped reinforcing frame 31 is embedded in the connecting frame 1 11 and the connecting frame 2 21 , the positioning hole 1 24 and the positioning hole 2 34 overlap each other; the positioning cylinder 4 penetrates the positioning hole 1 24 and then embeds into the positioning hole 2 34 .

[0043] Specifically, the diameter of the positioning cylinder 4 is the same as the inner diameter of the positioning hole 1 24 , and the inner diameter of the positioning hole 2 34 is the same as the inner diameter of the positioning hole 1 24 .

[0044] Specifically, an ejection hole 35 is formed through the bottom of the second positioning hole 34 on the L-shaped reinforcement frame 31 , and the inner diameter of the ejection hole 35 is smaller than the inner diameter of the second positioning hole 34 .

[0045] As can be seen from the above, the positioning cylinder 4 is passed through the positioning hole 1 24. Since its diameter is the same as the inner diameter of the positioning hole 1 24 and the positioning hole 2 34, the positioning cylinder 4 can be smoothly embedded in the positioning hole 2 34, thereby further stabilizing the connection between the L-shaped reinforcement frame 31 and the connecting frame 1 11 and the connecting frame 21;

[0046] When disassembly is required, the positioning cylinder 4 can be ejected from the bottom of the L-shaped reinforcement frame 31 through the ejection hole 35 using appropriate tools. Since the inner diameter of the ejection hole 35 is smaller than the inner diameter of the second positioning hole 34, it can effectively limit the falling of the positioning cylinder 4, but allows the ejection operation when necessary, thereby realizing convenient disassembly and assembly of the device.
