Description

Technical Field

[0001] This utility model relates to the field of component connection technology, and in particular to a mortise and tenon connection structure. Background Technology

[0002] Mortise and tenon joints are widely used in building materials, home furnishings, and handicrafts, especially in timber-framed structures, due to their advantages such as strong connections, ease of assembly and disassembly, flexibility, good earthquake resistance, no need for nails, and environmental pollution. Various types of mortise and tenon joints exist, the most common being the dovetail joint. Like other mortise and tenon joints, the dovetail joint provides a strong connection. However, assembling and disassembling a dovetail joint presents challenges. First, it requires moving one of the components to align the tenon (or tenon head) with the mortise (or tenon hole). Given the large size and weight of this component, this is time-consuming, labor-intensive, and difficult to assemble. Second, to allow the tenon (or tenon head) to enter the mortise (or tenon hole) for assembly, or to allow it to exit for disassembly, it is often necessary to strike the component, applying force. Directly striking or applying force to the component can easily cause damage, even permanent damage. Utility Model Content

[0003] The purpose of this utility model is to provide a mortise and tenon connection structure.

[0004] The technical solution to achieve the purpose of this utility model is: a mortise and tenon connection structure, including a first connector, a second connector, and a positioning block; the connecting end of the first connector has a first boss protruding outward in a direction perpendicular to the end face, the non-protruding part of the connecting end of the first connector forms a first recessed platform, the first boss is located at the edge of the connecting end of the first connector and forms a two-step structure with the first recessed platform, the first boss is provided with a first tenon protruding outward, the first recessed platform is provided with a first mortise groove, and a first groove is provided on the first step wall formed between the first boss and the first recessed platform; the connecting end of the second connector has a second boss protruding outward in a direction perpendicular to the end face, the non-protruding part of the connecting end of the second connector forms a second recessed platform, the second boss is located at the edge of the connecting end of the second connector and forms a two-step structure with the second recessed platform, the second boss is provided with a second tenon protruding outward, the second recessed platform is provided with a second mortise groove, and a second groove is provided on the second step wall formed between the second boss and the second recessed platform.

[0005] The first boss of the first connector is opposite to and fits against the second countersunk of the second connector. The first tenon is located in the second mortise and engages with the second mortise. The first countersunk of the first connector is opposite to and fits against the second boss of the second connector. The second tenon is located in the first mortise and engages with the first mortise. The first groove and the second groove are opposite to each other and surround to form a positioning hole with at least one end through. The positioning block is inserted into the positioning hole and fits with the positioning hole.

[0006] Furthermore, the first tenon is located on the side edge of the first boss near the first countersunk platform. This structure is not only easy to manufacture, but also allows for quick alignment of the first tenon and the second mortise during assembly through the contact between the first step wall and the second step wall, making assembly more convenient.

[0007] Furthermore, the second tenon is located on the side edge of the second boss near the second countersunk platform. This structure is not only easy to manufacture, but also allows for quick alignment of the second tenon and the first mortise during assembly through the contact between the first and second step walls, making assembly more convenient.

[0008] Furthermore, the positioning hole is a through hole extending from both ends. The positioning hole is perpendicular to the two side surfaces of the first connector and the second connector. This design facilitates the insertion and installation of the positioning block.

[0009] Furthermore, both the first connector and the second connector are wooden connectors, and the positioning block is a wooden positioning block.

[0010] In this utility model, during the assembly process of the mortise and tenon connection structure, the cooperation between the first tenon and the second mortise, and the second tenon and the first mortise, during the assembly of the first and second connecting parts, completes the longitudinal positioning of the first and second connecting parts. After the first and second connecting parts are assembled, the positioning block is inserted into the positioning hole formed by the assembly of the first and second connecting parts. The positioning block and the positioning hole limit the lateral positioning of the first and second connecting parts, thus achieving connection between the first and second connecting parts with longitudinal and lateral positioning. In this connection structure, the longitudinal and lateral positioning of the first and second connecting parts is not completed by the first and second connecting parts in one step, but in two steps. The assembly of the first and second connecting parts is responsible for the longitudinal positioning; the insertion of the positioning block is responsible for the lateral positioning. Since the first and second connectors are only responsible for longitudinal positioning during assembly, they can be quickly assembled once aligned in one direction. The assembly of the first and second connectors is quick and labor-saving. Furthermore, during the final connection, the force applied by the impact is to the positioning block, not the first and second connectors, to achieve engagement. Therefore, the first and second connectors will not be damaged by the impact, resulting in better stability and higher quality after connection. Even if the positioning block is damaged by the impact, it can be easily replaced. Attached Figure Description

[0014] The preferred embodiment of the mortise and tenon connection structure of this utility model will be described in detail below with reference to the accompanying drawings:

[0015] like Figures 1 to 3As shown, a mortise and tenon joint structure includes a first connector 1, a second connector 2, and a positioning block 3. The connecting end of the first connector 1 has a first boss 11 protruding outward in a direction perpendicular to its end face. The non-protruding portion of the connecting end of the first connector 1 forms a first countersunk platform 12. The first boss 11 is located at the edge of the connecting end of the first connector 1 and forms a two-step structure with the first countersunk platform 12. The first boss 11 has a first tenon 13 protruding outward, and the first countersunk platform 12 has a first mortise 14. The first boss 11 and the first countersunk platform 12 form a first tenon 13 protruding outward. A first groove 15 is provided on a stepped wall 10; a second boss 21 protrudes outward from the connecting end of the second connector 2 in a direction perpendicular to the end face; the non-protruding part of the connecting end of the second connector 2 forms a second recessed platform 22; the second boss 21 is located at the edge of the connecting end of the second connector 2 and forms a two-step structure with the second recessed platform 22; a second tenon 23 protrudes outward from the second boss 21; a second mortise 24 is provided on the second recessed platform 22; a second groove 25 is provided on the second stepped wall 20 formed between the second boss 21 and the second recessed platform 22.

[0016] The first boss 11 of the first connector 1 is opposite to and fits against the second countersunk 22 of the second connector 2. The first tenon 13 is located in the second mortise 24 and engages with the second mortise 24. The first countersunk 12 of the first connector 1 is opposite to and fits against the second boss 21 of the second connector 2. The second tenon 23 is located in the first mortise 14 and engages with the first mortise 14. The first groove 15 and the second groove 25 are opposite to each other and surround to form a positioning hole 30 with at least one end through. The positioning block 3 is inserted into the positioning hole 30 and fits with the positioning hole 30.

[0017] In this utility model, the mortise and tenon connection structure is assembled by first assembling the first connector 1 and the second connector 2, inserting the first tenon 13 into the second mortise 24 and the second tenon 23 into the first mortise 14; then, the positioning block 3 is inserted into the positioning hole 30 to complete the connection. For disassembly, the positioning block 3 is removed first, and then the first connector 1 and the second connector 2 are separated.

[0018] This utility model relates to a mortise and tenon connection structure. The first tenon 13 is located within and engages with the second mortise 24, serving to longitudinally limit the movement of the first connector 1 and the second connector 2. The second tenon 23 is located within and engages with the first mortise 14, also serving to longitudinally limit the movement of the first connector 1 and the second connector 2. The positioning block 3 is inserted into and engages with the positioning hole 30, serving to laterally limit the movement of the first connector 1 and the second connector 2. With both longitudinal and lateral limits, the first connector 1 and the second connector 2 form a stable connection.

[0019] In this utility model, during the assembly process of the mortise and tenon connection structure, when the first connecting piece 1 and the second connecting piece 2 are assembled, the cooperation of the first tenon 13 and the second mortise 24, and the second tenon 23 and the first mortise 14, completes the longitudinal limiting of the first connecting piece 1 and the second connecting piece 2. After the first connecting piece 1 and the second connecting piece 2 are assembled, the positioning block 3 is inserted into the positioning hole 30 formed by the assembly of the first connecting piece 1 and the second connecting piece 2. The positioning block 3 and the positioning hole 30 are used to limit the lateral movement of the first connecting piece 1 and the second connecting piece 2. The first connecting piece 1 and the second connecting piece 2 are thus connected by the longitudinal and lateral limiting. In this connection structure, the longitudinal and lateral limiting of the first connecting piece 1 and the second connecting piece 2 is not completed by the first connecting piece 1 and the second connecting piece 2 at one time, but in two stages. The assembly of the first connecting piece 1 and the second connecting piece 2 is responsible for the longitudinal limiting; the insertion of the positioning block 3 is responsible for the lateral limiting. Since the first connector 1 and the second connector 2 are only responsible for limiting the longitudinal direction during assembly, they can be quickly assembled after being aligned in one direction. The assembly of the first connector 1 and the second connector 2 is quick and labor-saving. Moreover, during the final connection, in order to achieve the locking, the force of the impact is on the positioning block 3, not the first connector 1 and the second connector 2. The first connector 1 and the second connector 2 will not be damaged by the impact. The first connector 1 and the second connector 2 have better stability when connected and the quality is more guaranteed after connection. Even if the positioning block 3 is damaged by the impact, it can be easily replaced.

[0020] In this utility model, the mortise and tenon connection structure uses two mating structures—the first tenon 13 and the second mortise 24, and the second tenon 23 and the first mortise 14—to longitudinally limit the first connector 1 and the second connector 2, ensuring reliable longitudinal positioning. Furthermore, the mating structures of the first tenon 13 and the second mortise 24, the second tenon 23 and the first mortise 14, the positioning block 3, and the positioning hole 30 are not only small and highly concealed, but also arranged in a cross shape, resulting in an aesthetically pleasing connection structure.

[0021] This utility model's mortise and tenon joint structure, through a scientific connection method, allows the first connector 1 and the second connector 2 to be more tightly connected together, forming a sturdy whole. This structure reduces the use of other connecting mechanisms, thereby lowering the probability of product failure and making transportation, installation, and use more stable and convenient. Furthermore, the disassembly and assembly scheme of this structure makes product maintenance more convenient, faster, and less labor-intensive.

[0022] In this utility model, the tenon and mortise connection structure preferably has the first tenon 13 located on the edge of the first boss 11 near the first countersunk platform 12. This structure is not only easy to process, but also allows for quick alignment of the first tenon 13 and the second mortise 24 during assembly through the contact between the first stepped wall 10 and the second stepped wall 20, making assembly more convenient.

[0023] In this utility model, the mortise and tenon connection structure preferably has the second tenon 23 located on the edge of the second boss 21 near the second countersunk platform 22. This structure is not only easy to process, but also allows for quick alignment of the second tenon 23 and the first mortise 14 during assembly through the contact between the first stepped wall 10 and the second stepped wall 20, making assembly more convenient.

[0024] In this utility model's mortise and tenon connection structure, preferably, the positioning hole 20 is a through hole extending from both ends. The positioning hole 20 is perpendicular to the two side surfaces of the first connector 1 and the second connector 2. This arrangement facilitates the insertion and installation of the positioning block 3.

[0025] The mortise and tenon connection structure of this utility model can be used, but is not limited to, as a connection structure for wooden components. It can also be used as a connection structure for steel components and stone components. Preferably, the first connector 1 and the second connector 2 are both wooden connectors, and the positioning block 3 is a wooden positioning block.

[0026] For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model, and all such deductions or substitutions should be considered to fall within the protection scope of this utility model.
