Description

Technical Field

[0001] The utility model belongs to the technical field of the connection of component structures, and particularly relates to a mortise and tenon sleeve connection structure. Background Art

[0002] At present, the connection processes for making wooden utensils mainly include several basic methods such as countersunk screws, right-angle corner brackets, wooden tenon gluing, and mortise and tenon structures. However, these methods all have obvious defects, which are specifically as follows:

[0003] The countersunk screw method requires pre-positioning holes, which not only increases the installation difficulty but also cannot achieve non-destructive disassembly, and it is difficult to ensure firmness due to the influence of materials and processes. The right-angle corner bracket method requires larger-sized wood materials, and it is not suitable for woods with softer textures and prone to deformation and cracking such as pine, and it will seriously damage the beauty of the overall utensil. The wooden tenon gluing method has high requirements for materials, and it is difficult and time-consuming to make. It not only requires professional techniques and experience but also increases the transportation cost of the whole set of utensils. The mortise and tenon structure method requires the use of high-quality solid wood, and each tenon and mortise must be joined according to the shape of the utensil. Therefore, the manufacturing process is complex and requires superb skills and rich experience, and the high processing accuracy requirements also increase the manufacturing difficulty and cost. The mortise and tenon structure is not easy to be mass-produced, resulting in low efficiency, not easy to disassemble, resulting in high transportation costs, and must have professional woodworking skills, resulting in difficult later maintenance. In addition, these methods are not convenient for making non-right-angle components with different included angles, thus further increasing the difficulty of making wooden utensils.

Therefore, it should not be construed as a limitation to the present utility model.

[0038] The present utility model will be further described below with reference to the drawings.

[0039] Embodiment 1

[0040] As shown in Figure 1 , 2 and 3, a mortise and tenon sleeve connection structure can connect the profile parts of components with various shapes, and then form a complete component. The profile parts of the component can be wooden strips, boards, etc. This connection structure includes a mortise and tenon joint and a connecting sleeve 4. Among them, a socket block 3 is provided at the rear end of the mortise and tenon joint. A socket block 3 is provided at the rear end of each of the tenon joint 1 and the mortise joint 2, and the inner sections of the two connecting sleeves 4 can be respectively sleeved on the two socket blocks 3. A profile part of a component is sleeved on the outer section of each of the two connecting sleeves 4.

[0041] Furthermore, the mortise and tenon joint includes a tenon joint 1 and a mortise joint 2. The front ends of the tenon joint 1 and the mortise joint 2 are insertion parts 5. A socket block 3 is provided at the rear end of each of the tenon joint 1 and the mortise joint 2, and the socket block 3 is the socket part. The protruding part of the insertion part 5 is provided on the tenon joint 1, while the concave part of the insertion part 5 that is inserted and matched is provided on the mortise joint 2. The two connecting sleeves 4 are sleeved on the two socket blocks 3, thereby realizing the connection of the two components of the tenon joint 1 assembly and the mortise joint 2 assembly.

[0042] During specific assembly, first, insert the convex part of the insertion portion 5 of the tenon joint 1 into the concave part of the insertion portion 5 of the mortise joint 2, and respectively sleeve two connecting sleeves 4 onto the socket blocks 3 at the rear ends of the tenon joint 1 and the mortise joint 2. Secondly, respectively sleeve the two connecting sleeves 4 onto the docking socket blocks at the front ends of the two component profile parts to be connected, thereby completing the rapid connection of the two component profile parts. Consumers can purchase tenon and mortise sleeve assemblies of specific types and specifications according to their personal needs, and then purchase matching wood according to the specifications. It is not only extremely simple to manufacture, but also can greatly reduce transportation costs. When a part in the component profile part or the connection structure is damaged, only need to disassemble the damaged part and replace it with a new one. The later maintenance is very easy, and almost everyone can do it by themselves.

[0043] In this embodiment, the socket block 3 can be a square column, a rectangular column, a polygonal column or a cylinder.

[0044] Furthermore, the tenon joint 1, the connecting sleeve 4 and the mortise joint 2 are formed by processes such as injection molding, extrusion and casting. Therefore, tenon and mortise sleeve assemblies of various types and various standard specifications can be mass-produced, effectively solving the problems of complex manufacturing process and high processing precision requirements of the tenon and mortise structure, which are inefficient and costly.

[0045] Embodiment 2

[0046] As Figure 1 shown, the difference between this embodiment and Embodiment 1 is that a mortise fixing hole 6 is provided on the insertion portion 5 of the tenon joint 1. A tenon fixing hole 7 that matches the mortise fixing hole 6 is provided on the insertion portion 5 of the mortise joint 2. When the convex part of the insertion portion 5 of the tenon joint 1 is inserted to the end of the concave part of the insertion portion 5 of the mortise joint 2, the tenon fixing hole 7 communicates with the mortise fixing hole 6. By inserting a first fixing member into the tenon fixing hole 7 and the mortise fixing hole 6, the relative position between the tenon joint 1 and the mortise joint 2 is locked.

[0047] Furthermore, sleeve fixing holes 8 are provided on both socket blocks 3 of the tenon joint 1 and the mortise joint 2. A socket fixing hole 9 that matches the sleeve fixing hole 8 on the socket block 3 is provided on the connecting sleeve 4. When the connecting sleeve 4 is sleeved on the socket block 3, the socket fixing hole 9 communicates with the sleeve fixing hole 8. By inserting a second fixing member into the socket fixing hole 9 and the sleeve fixing hole 8, the relative positions between the tenon joint 1 and the mortise joint 2 and their respective connecting sleeves 4 are locked.

[0048] In this embodiment, both the first fixing member and the second fixing member are dowel pins.

[0049] Further, a docking fixing hole 10 is provided in an outer section of the connecting sleeve 4. A mating connecting hole is provided on the docking socket block at the front end of the component profile part sleeved in the connecting sleeve 4. When the docking socket block at the front end of the component profile part is inserted into the connecting sleeve 4, the connecting hole communicates with the docking fixing hole 10. By inserting a pin into the connecting hole and the docking fixing hole 10, the relative position between the component profile part and the connecting sleeve 4 is locked.

[0050] Embodiment 3

[0051] As Figure 4 shown, the difference between this embodiment and Embodiment 2 is that the mortise and tenon joint has various basic types such as 90 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, 150 degrees, 155 degrees, 160 degrees, 165 degrees, 170 degrees, 175 degrees, and 180 degrees.

[0052] Among them, for the 90-degree mortise and tenon joint, the included angle between the central axis of the insertion part 5 of the mortise and tenon joint and the central axis of the connecting sleeve 4 is 90 degrees, so that when the component profile part is inserted into an outer section of the connecting sleeve 4, its central axis can form a fixed 90-degree included angle with the central axis of the insertion part 5 of the mortise and tenon joint.

[0053] For the 95-degree mortise and tenon joint, the included angle between the central axis of the insertion part 5 of the mortise and tenon joint and the central axis of the connecting sleeve 4 is 95 degrees, so that when the component profile part is inserted into an outer section of the connecting sleeve 4, its central axis can form a fixed 95-degree included angle with the central axis of the insertion part 5 of the mortise and tenon joint.

[0054] Similarly, for the 160-degree mortise and tenon joint, the included angle between the central axis of the insertion part 5 of the mortise and tenon joint and the central axis of the connecting sleeve 4 is 160 degrees, so that when the component profile part is inserted into an outer section of the connecting sleeve 4, its central axis can form a fixed 160-degree included angle with the central axis of the insertion part 5 of the mortise and tenon joint. For the subsequent types, it can be inferred by analogy. In this solution, when purchasing, consumers must buy mortise and tenon joints with specific angles according to current needs.

[0055] Embodiment 4

[0056] As Figure 5 and 6 shown, the difference between this embodiment and Embodiment 3 is that the cross-sections of both socket blocks 3 are right trapezoids, so that the socket blocks 3 can swing unidirectionally in the corresponding connecting sleeves 4, and thus the inclination angle of the insertion part 5 of the mortise and tenon joint relative to the connecting sleeve 4 can be adjusted.

[0057] In this embodiment, a plurality of sleeve fixing holes 8 are provided on the two socket blocks 3. During assembly, the socket block 3 is swung to the required angle. The sleeve fixing holes 8 on the socket block 3 communicate with the socket fixing holes 9 on the connecting sleeve 4. By inserting pins into the socket fixing holes 9 and the sleeve fixing holes 8, the locking of the angles and positions between the tenon joint 1 and the mortise joint 2 and their respective connecting sleeves 4 is achieved.

[0058] Furthermore, the tenon-mortise joint has multiple basic types such as 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, and 180 degrees.

[0059] Among them, the 100-degree tenon-mortise joint adopts the fixed angle of the 100-degree tenon-mortise joint in Embodiment 3, and through the adjustable angle of the socket block 3 with a right trapezoidal structure, a plurality of adjustable included angles from 90 degrees to 100 degrees can be synthesized between the tenon-mortise joint and the component profile part, such as 90-degree included angle, 92.5-degree included angle, 95-degree included angle, 97.5-degree included angle, and 100-degree included angle, etc.

[0060] The 110-degree tenon-mortise joint adopts the fixed angle of the 110-degree tenon-mortise joint in Embodiment 3, and through the adjustable angle of the socket block 3 with a right trapezoidal structure, a plurality of adjustable included angles from 100 degrees to 110 degrees can be synthesized between the tenon-mortise joint and the component profile part, such as 100-degree included angle, 102.5-degree included angle, 105-degree included angle, 107.5-degree included angle, and 110-degree included angle, etc. The subsequent types follow this analogy. Although there may be a problem of fine gaps affecting the appearance in this scheme, the manufacturer can significantly reduce the number of molds, improve production efficiency, and greatly reduce inventory. When purchasing, consumers can flexibly choose to buy a tenon-mortise joint at a certain angle according to current needs and future applications.

[0061] Embodiment 5

[0062] The difference between this embodiment and Embodiment 1 is that the tenon joint 1 and the mortise joint 2 are integrally formed with their respective connecting sleeves 4. The cross-sectional shape of a section of the inner cavity on the outer side of the connecting sleeve 4 can be selected as square, rectangular, polygonal, or circular.

[0063] Embodiment 6

[0064] As Figure 2 、 7 and shown in 8, the difference between this embodiment and Embodiment 1 is that between the insertion part 5 of the tenon joint 1 and the insertion part 5 of the mortise joint 2, and between the socket block 3 and the connecting sleeve 4, a first snap structure and a second snap structure are provided to further ensure the locking of the relative positions between the tenon joint 1, the mortise joint 2, and the connecting sleeve 4.

[0065] Specifically, the first snap structure includes a mortise snap 11 provided at the insertion part 5 of the tenon joint 1, and a tenon snap groove 12 opened at one side of the end of the concave part of the insertion part 5 of the mortise joint 2. Among them, the mortise snap 11 is integrally formed with the insertion part 5 of the tenon joint 1 and is made of plastic material. During assembly, by snapping the mortise snap 11 into the tenon snap groove 12, a limitation in the insertion and extraction direction between the tenon joint 1 and the mortise joint 2 is formed.

[0066] Furthermore, a relief groove is provided at the insertion part 5 of the tenon joint 1 and is matched with the mortise snap 11, which can provide a deformation space for the deformation of the mortise snap 11 during the process of the mortise snap 11 being inserted into the concave part of the insertion part 5 of the mortise joint 2.

[0067] The second snap structure includes a sleeve snap 13 provided on the socket part of the mortise and tenon joint, and a socket snap groove 14 opened on the connecting sleeve 4. An installation groove for cooperating with the sleeve snap 13 is provided on the socket block 3. The sleeve snap 13 is arranged in the installation groove and is integrally formed with the socket block 3. Among them, the bottom surface of the sleeve snap 13 is spaced from the bottom surface of the installation groove, providing a deformation space for the sleeve snap 13. During the process of the connecting sleeve 4 being sleeved on the socket block 3, the sleeve snap 13 deforms due to abutting against the inside of the connecting sleeve 4. When the sleeve snap 13 is aligned with the socket snap groove 14 on the connecting sleeve 4, the sleeve snap 13 resets and snaps into the socket snap groove 14, thereby realizing the position limitation in the insertion and extraction direction between the connecting sleeve 4 and the socket block 3.

[0068] Embodiment 7

[0069] The difference between this embodiment and Embodiment 4 is that the cross-section of the socket block 3 is in the shape of a right trapezoid. When the socket block 3 is inserted into the connecting sleeve 4, a space for vertical movement is left between the top surface of the socket block 3 and the connecting sleeve 4. The user can move the socket block 3 up and down according to needs. The top and bottom of the socket block 3 are fixed to the top and bottom surfaces of the connecting sleeve 4 through limit bolts.

[0070] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
