[0005] This utility model is achieved using the following technical solution: a magnetic ring with a mortise and tenon joint structure, including a magnetic ring one, a mounting groove on the left side of the magnetic ring one, a connecting block slidably connected to the inner wall of the mounting groove, a magnetic ring two fixedly connected to the end of the connecting block away from the magnetic ring one, a clearance groove on the top of the magnetic ring one, a limiting groove at the bottom of the clearance groove, a limiting pin one slidably connected to the inner wall of the limiting groove, a limiting pin two slidably connected to the surface of the limiting pin one, a guide groove on the surface of the limiting pin one, and a mortise and tenon pin slidably connected to the inner wall of the guide groove.
[0006] As a further improvement to the above solution, the mortise and tenon pin penetrates the bottom of the first limiting pin and extends thereafter, the outer wall of the mortise and tenon pin is slidably connected to the inner wall of the second limiting pin, and the bottom of the mortise and tenon pin penetrates the inner wall of the second limiting pin and extends thereafter.
[0007] With the above technical solution, when the magnetic ring 2 drives the connecting block to be installed into the installation groove opened in the magnetic ring 1, the limiting pin 1 and the limiting pin 2 are installed into the clearance groove, so that the limiting pin 1 and the limiting pin 2 fall into the limiting groove. Then, the mortise and tenon pin is installed through the guide groove opened in the limiting pin 1 and the limiting pin 2, so that the mortise and tenon pin pushes the limiting pin 1 and the limiting pin 2 to both sides.
[0008] As a further improvement to the above solution, a T-shaped groove is provided at the bottom of the first limiting pin, and a T-shaped slider is slidably connected to the inner wall of the T-shaped groove. The bottom of the T-shaped slider is fixedly connected to the surface of the second limiting pin.
[0009] As a further improvement to the above solution, a T-shaped groove is provided on the top of the second limiting pin, and a T-shaped slider is slidably connected to the inner wall of the second T-shaped groove. The top of the second T-shaped slider is fixedly connected to the surface of the first limiting pin.
[0010] As a further improvement to the above solution, two T-shaped slides are provided, and the two T-shaped slides are symmetrically arranged with the mortise and tenon pin as the center. Two T-shaped slides are provided, and the two T-shaped slides are symmetrically arranged with the mortise and tenon pin as the center.
[0011] As a further improvement to the above solution, a disassembly hole is provided on the surface of the magnetic ring one, and a clearance groove two is provided on the left side of the magnetic ring one. A rotating rod is fixedly connected to the inner wall of the clearance groove two, and the outer wall of the rotating rod is rotatably connected to the inner wall of the magnetic ring two.
[0012] As a further improvement to the above solution, a limiting groove is provided at the top of the magnetic ring, and a malleable limiting buckle is provided on the inner wall of the limiting groove, and the surface of the malleable limiting buckle is provided on the top of the mortise and tenon pin.
[0013] Through the above technical solution, while the first and second limiting pins slide into the limiting groove, the first limiting pin drives the second T-shaped slider to slide along the second T-shaped slide groove, and the second limiting pin drives the second T-shaped slider to slide along the T-shaped slide groove, making the connection between the first and second limiting pins more stable.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention, when the connecting block is installed into the mounting groove of the first magnetic ring, the first magnetic ring and the second magnetic ring are installed into the clearance groove, allowing the first and second limiting pins to fall into the limiting groove. Then, the mortise and tenon pin is installed through the guide grooves of the first and second limiting pins, causing the mortise and tenon pin to push the first and second limiting pins to expand into the limiting groove. This expansion of the limiting pins limits the connecting block, preventing it from detaching from the mounting groove and improving the stability of the connection between the first and second magnetic rings. This structure makes the magnetic ring connection more secure. In environments requiring vibration or impact, the mortise and tenon joint structure of the magnetic ring provides a more stable connection than ordinary magnetic rings, preventing loosening or breakage. It also allows the magnetic ring to distribute stress under force or vibration, reducing material loss and extending its service life. In contrast, ordinary magnetic rings, if simply fixed with adhesive or mechanical means, may develop problems such as loosening and aging during long-term use.
[0016] This invention, by having limit pin one and limit pin two slide into the limit groove while limit pin one drives T-shaped slider two to slide along T-shaped slide groove two, and limit pin two drives T-shaped slider two to slide along T-shaped slide groove two, makes the connection between limit pin one and limit pin two more stable. When it is necessary to separate magnetic ring one and magnetic ring two, the plastic limit buckle can be removed outward, and then the mortise and tenon pin can be removed upward, so that the mortise and tenon pin loses its limit on limit pin one and limit pin two. Then, limit pin one and limit pin two can be pushed through the disassembly hole, so that limit pin one and limit pin two retract inward. Then, limit pin one and limit pin two can be removed upward along the clearance groove for easy operation of the product. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0029] Example:
[0030] Please combine Figure 1-9 This embodiment of a magnetic ring with a mortise and tenon joint structure includes a magnetic ring 1. A mounting groove 2 is provided on the left side of the magnetic ring 1. A connecting block 3 is slidably connected to the inner wall of the mounting groove 2. A magnetic ring 4 is fixedly connected to the end of the connecting block 3 away from the magnetic ring 1. A clearance groove 5 is provided on the top of the magnetic ring 1. A limiting groove 6 is provided at the bottom of the clearance groove 5. A limiting pin 7 is slidably connected to the inner wall of the limiting groove 6. A limiting pin 8 is slidably connected to the surface of the limiting pin 7. A guide groove 9 is provided on the surface of the limiting pin 7. A mortise and tenon pin 10 is slidably connected to the inner wall of the guide groove 9.
[0031] The mortise and tenon pin 10 penetrates the bottom of the limiting pin 1 7 and extends thereafter. The outer wall of the mortise and tenon pin 10 is slidably connected to the inner wall of the limiting pin 2 8. The bottom of the mortise and tenon pin 10 penetrates the inner wall of the limiting pin 2 8 and extends thereafter.
[0032] The bottom of the limiting pin 7 is provided with a T-shaped groove 11, and a T-shaped slider 12 is slidably connected to the inner wall of the T-shaped groove 11. The bottom of the T-shaped slider 12 is fixedly connected to the surface of the limiting pin 8.
[0033] The top of the limiting pin 8 is provided with a T-shaped groove 13, and a T-shaped slider 14 is slidably connected to the inner wall of the T-shaped groove 13. The top of the T-shaped slider 14 is fixedly connected to the surface of the limiting pin 7.
[0034] Two T-shaped slides 11 are provided, and the two T-shaped slides 11 are symmetrically arranged with the mortise and tenon pin 10 as the center. Two T-shaped slides 13 are provided, and the two T-shaped slides 13 are symmetrically arranged with the mortise and tenon pin 10 as the center.
[0035] The surface of magnetic ring 1 has a disassembly hole 15, and the left side of magnetic ring 1 has a relief groove 16. A rotating rod 17 is fixedly connected to the inner wall of relief groove 16, and the outer wall of rotating rod 17 is rotatably connected to the inner wall of magnetic ring 4.
[0036] A limiting groove 18 is provided at the top of the magnetic ring 1. A malleable limiting buckle 19 is provided in contact with the inner wall of the limiting groove 18. The surface of the malleable limiting buckle 19 is provided in contact with the top of the mortise and tenon pin 10.
[0037] The implementation principle of a magnetic ring with a mortise and tenon joint structure in this embodiment is as follows: By rotating the magnetic ring 4 around the rotating rod 17, the magnetic ring 4 rotates along the clearance groove 16, thereby causing the magnetic ring 4 to drive the connecting block 3 to slide towards the inner wall of the mounting groove 2 opened by the magnetic ring 1. By installing the limiting pin 7 and the limiting pin 8 into the clearance groove 5, the limiting pin 7 and the limiting pin 8 fall into the limiting groove 6. Then, the mortise and tenon pin 10 is installed through the guide groove 9 opened by the limiting pin 7 and the limiting pin 8, thereby making the mortise and tenon joint... The tenon pin 10 pushes the limiting pins 7 and 8 to both sides, causing them to expand into the limiting groove 6. Simultaneously, limiting pin 7 drives T-shaped slider 14 to slide along T-shaped groove 13, and limiting pin 8 drives T-shaped slider 12 to slide along T-shaped groove 11. This expands the limiting pins 7 and 8 to limit the connecting block 3, preventing it from detaching from the mounting groove 2 and improving the stability of the connection between magnetic ring 1 and magnetic ring 4. This structure makes the magnetic ring connection more robust. In environments requiring vibration or impact, the mortise and tenon joint structure provides a more stable connection than ordinary magnetic rings, preventing loosening or breakage. It also allows the magnetic ring to distribute stress under pressure or vibration, reducing material loss and extending its service life. In contrast, ordinary magnetic rings may loosen or age over long-term use if they are simply fixed with glue or mechanical means. By installing the malleable limiting buckle 19 into the limiting groove 18, the limiting groove 18 limits the malleable limiting buckle 19. At the same time, the bottom surface of the malleable limiting buckle 19 limits the top of the mortise and tenon pin 10, preventing the mortise and tenon pin 10 from dislodging from the limiting pin 7 and the limiting pin 8.
[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
