Description

Technical Field

[0001] This utility model relates to the field of gasket connection technology, and in particular to a tongue and groove tenon joint structure. Background Technology

[0002] The tenon and mortise joint, a common mechanical connection method, is widely used in machinery manufacturing, building component assembly, and composite material connection. This structure relies primarily on the geometric matching between the tenon and mortise to achieve connection, ensuring a certain level of assembly accuracy and overall stability without the need for additional fasteners. Therefore, it is highly suitable for applications requiring rapid assembly and repeated disassembly.

[0003] In existing technologies, the connection between gaskets and substrates is mostly achieved through bolting, welding, or adhesive bonding. These methods typically rely on mechanical fastening or material bonding to achieve the connection. The technical principle is to ensure the bonding strength between parts by applying external constraint force or the hardening reaction of the adhesive, thereby meeting the requirements for mechanical performance and stability.

[0004] However, existing connection methods still have certain problems in application. Since bolted connections, welding, or bonding all require additional fasteners, welding equipment, or adhesives, they are not only cumbersome to operate, but also difficult to guarantee high connection accuracy during assembly, especially in situations requiring multiple disassemblies or rapid reassemblies, resulting in low efficiency and inconvenience. Therefore, how to achieve a tenon joint structure that can guarantee connection accuracy while also possessing a self-locking effect has become a technical problem that needs to be solved. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tongue and groove tenon structure, which aims to improve the inconvenience of using bolts, welding or bonding to connect the gasket and the substrate.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tenon and mortise joint structure, comprising: The substrate and the liner, both of which are used to support the whole; A connecting assembly is disposed between the substrate and the gasket, and the connecting assembly is used to connect the substrate and the gasket; An auxiliary component is disposed inside the connecting component and is used to assist in connecting the base and the gasket. A reinforcing component is disposed inside the connecting component, and the reinforcing component is used to improve the connection strength between the substrate and the gasket.

[0007] The above technical solution achieves the effect of ensuring connection accuracy and realizing self-locking.

[0008] Preferably, the connecting component includes a tenon, one side of which is fixedly connected to the side of the pad, and a groove is provided inside the base, the tenon fitting into the groove, and the tenon being made of magnetic material.

[0009] The above technical solution achieves a self-locking connection.

[0010] Preferably, the auxiliary component includes a magnet disposed inside the base, the base having an installation groove, the magnet engaging with the installation groove, and the magnet attracting the tenon.

[0011] The above technical solution achieves the effect of magnetic-assisted connection.

[0012] Preferably, the reinforcing component includes a locking strip, one side of which is fixedly connected to the outer wall of the tenon, and a locking groove is provided inside the base, with the locking strip fitting into the locking groove.

[0013] The above technical solution achieves the effect of improving connection stability.

[0014] Preferably, the outer surface of the tenon is provided with a second inclined surface, and the outer surface of the substrate is provided with a first inclined surface.

[0015] The above technical solution achieves the effect of guiding the connection of the tenon.

[0016] Preferably, the first and second inclined surfaces are used to guide the tenon to be embedded in the base.

[0017] The above technical solution achieves the effect of assisted connection.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the tenon on the pad first slides into the groove on the base. The inclined surface 2 on the outer wall of the tenon and the inclined surface 1 on the base guide each other to insert and lock in the vertical direction, which achieves the effect of ensuring connection accuracy and realizing self-locking. This solves the problem that the pad and the base are usually connected by bolts, welding or bonding, which is inconvenient, and improves the connection convenience of the pad and the base.

[0019] 2. In this utility model, the magnet inside the groove is installed in the mounting groove on the base. The tenon is made of magnetic material so that the mounting groove and the tenon attract each other to assist in the connection. At the same time, the two outer walls of the inclined surface are fitted into the locking groove on the base by the locking strip, which achieves the effect of improving the connection stability, solves the problem of lateral slippage after the connection of the traditional tenon structure, and improves the connection strength of the tenon structure.

[0022] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0023] Reference Figures 1-4 One embodiment of this utility model provides a tenon-and-groove joint structure, comprising: The base 1 and the pad 2 are both used to support the whole. The base 1 is the main load-bearing body, and its interior can form a corresponding accommodating space to ensure the installation and positioning of subsequent fitting parts. The pad 2, as a component that cooperates with the base 1, plays the role of distributing the force and assisting in positioning in the whole. The base 1 and the pad 2 form the basic support structure in the whole. A connecting component is disposed between the base 1 and the gasket 2. The connecting component is used to connect the base 1 and the gasket 2 so that the two can form a stable joint relationship during the assembly process and prevent relative displacement between the two due to external force or vibration during use. The auxiliary component is located inside the connecting component. The auxiliary component is used to assist in connecting the base 1 and the pad 2, ensuring a higher fit during the process of the tenon 3 being inserted into the groove 4, and improving the stability of the fit through adsorption. The reinforcing component is located inside the connecting component. The reinforcing component is used to improve the connection strength between the base 1 and the pad 2, so that the two can still maintain a stable connection when there is a large load or impact force externally, and prevent problems such as loosening or separation.

[0024] The connecting component includes a tenon 3, one side of which is fixedly connected to one side of the pad 2. As the active component of the connection, the tenon 3 extends from the pad 2 towards the base 1 during overall assembly, and its shape matches the corresponding groove 4 inside the base 1. The base 1 has a groove 4 inside, and the tenon 3 engages with the groove 4. This engagement provides a preliminary mechanical restraint effect, ensuring that the pad 2 and the base 1 maintain a relatively fixed connection after assembly. To further enhance the stability of the engagement, the tenon 3 is made of magnetic material. When it interacts with the magnet 5 in the corresponding auxiliary component, it forms a reliable magnetic attraction effect, thus avoiding the shaking or loosening problems that occur when relying solely on mechanical engagement.

[0025] The auxiliary component includes a magnet 5, which is disposed inside the base 1. The magnet 5 acts as a passive mating component, interacting with the tenon 3 and fixed in position on the base 1. This ensures a precise correspondence between the magnet 5 and the tenon 3 during insertion into the groove 4. An installation groove 8 is provided inside the base 1, and the magnet 5 engages with it. The limiting effect of the installation groove 8 keeps the magnet 5 stationary, preventing displacement due to external forces or vibrations during long-term use. The magnet 5 attracts the tenon 3, and the magnetic force further enhances the attraction on top of the mechanical engagement, making the connection between the base 1 and the pad 2 more stable, thereby improving overall reliability.

[0026] The reinforcing component includes a locking strip 10, one side of which is fixedly connected to the outer wall of the tenon 3. As an anti-detachment element in the structure, the locking strip 10 further reinforces the connecting component by engaging with the inner part of the base 1 after the tenon 3 is inserted into the groove 4. A locking groove 7 is provided inside the base 1, and the locking strip 10 fits into the locking groove 7. Through the limiting effect of the fitting structure, it effectively prevents the tenon 3 from detaching from the groove 4 when subjected to external force, thereby significantly improving the safety and reliability of the connection. A second bevel 9 is provided on the outer surface of the tenon 3, and a first bevel 6 is provided on the outer surface of the base 1. The first bevel 6 and the second bevel 9 guide the tenon 3 into the base 1. Their cooperative design allows the tenon 3 to be gradually guided to the center position of the groove 4 during insertion, thereby reducing deviations and frictional resistance during assembly, and also improving assembly efficiency and accuracy.

[0027] Working principle: When using this tenon-and-groove joint structure, during the assembly and connection of the base 1 and the pad 2, the tenon 3 on the pad 2 gradually slides into the groove 4 set on the base 1 along the preset direction. During this insertion process, the inclined surface 9 on the outer wall of the tenon 3 interacts with the inclined surface 6 formed on the outer surface of the base 1. When they come into contact, they can form a guiding fit, so that the tenon 3 can be smoothly inserted into the groove 4 in the vertical direction under the guidance of the inclined surface. After the insertion is completed, a reliable locking effect is achieved. This structural design can not only ensure the connection accuracy between the base 1 and the pad 2, but also form a self-locking effect after the connection is completed, thereby preventing the connector from loosening or shifting in subsequent use. Secondly, a magnet 5 for auxiliary connection is provided inside the groove 4. The magnet 5 is pre-installed inside the mounting groove 8 opened on the base 1. The size and shape of the mounting groove 8 are adapted to the magnet 5, so that the magnet 5 can be stably fitted in the mounting groove 8. When the tenon 3 is inserted into the groove 4, since the tenon 3 is made of magnetic material, it can attract each other with the magnet 5 in the mounting groove 8, thereby further enhancing the connection effect between the base 1 and the pad 2. The setting of this magnetic attraction structure effectively improves the auxiliary fixing performance during the connection process, avoids the tenon 3 from shaking during the insertion process, and ensures the smoothness and reliability of the connection. Finally, to further enhance the connection strength, a reinforcing locking strip 10 is provided on the outer wall of the tenon 3. One side of the locking strip 10 is fixedly connected to the outer wall of the tenon 3, and a locking groove 7 corresponding to the locking strip 10 is opened inside the base 1. When the tenon 3 is inserted into the predetermined position of the groove 4, the locking strip 10 can form a fitting relationship with the locking groove 7 inside the base 1, thereby achieving stable locking of the tenon 3. In this process, the outer wall of the inclined surface 9 further improves the connection strength between the inclined surface 9 and the groove 4 through the fitting of the locking strip 10 and the locking groove 7. This makes the overall connection not only rely on magnetic adsorption to achieve initial positioning and auxiliary fixation, but also rely on the mechanical fitting structure to provide a high-strength fixing effect. Ultimately, this achieves the effect of improving the overall connection stability between the base 1 and the pad 2, ensuring the reliability and durability of the tenon joint structure in long-term use.
