Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example

[0049] See Figures 1 to 6 As shown, a magnetic button-type top and bottom lock structure includes an upper magnetic lock structure 1, a lower magnetic lock structure 2, and a middle button assembly 3. An upper lever line 4 is provided between the middle button assembly and the upper magnetic lock structure; a lower lever line 5 is provided between the middle button assembly and the lower magnetic lock structure. In this embodiment, the upper and lower lever lines are brake lines, meaning the upper lever line includes a sleeve and a steel wire body movably disposed within the sleeve. This not only ensures the effectiveness and smooth reliability of the transmission but also enables the synchronous effectiveness and smooth reliability of unlocking the upper and lower magnetic lock structures through the middle button assembly.

[0050] In this embodiment, the central button assembly 3 includes a housing 31, a lower shaft 32, a pressing plate 33, a return spring 34, an upper shaft 35, two support rods 36, two rocker arms 37, and two pins 38; in this embodiment, the housing, upper shaft, lower shaft, support rods, rocker arms, and locking pins are all metal structures.

[0051] During installation, the housing is provided with a hollow pressing cavity 6, the lower part of the pressing cavity is provided with a shaft hole 7, and the upper part of the pressing cavity is provided with a vertical guide groove 8. Because it is provided with a hollow pressing cavity, the upper and lower bar lines can be loosened and detached from the bottom of the pressing cavity of the housing, which improves the convenience and stability of installation.

[0052] Meanwhile, the two ends of the lower shaft are rotatably connected to the shaft hole; the bottom ends of the two support rods are rotatably connected to the two ends of the lower shaft; the middle part of the rocker arm is rotatably connected to the top end of the support rod via a pin; the two ends of the upper shaft are vertically adjustable within the vertical guide groove; the top end of the rocker arm is rotatably connected to the end of the upper shaft; the return spring is located between the upper shaft and the lower shaft; the upper lever and the lower lever are respectively screwed and fixed to the bottom ends of the two rocker arms; during operation, the pressing plate is located in the pressing cavity of the housing, and the pressing plate rises and falls, causing the two rocker arms to rotate around the pin, and driving the upper lever and the lower lever to move. When in use, press the pressing plate down to compress the return spring. At this time, the rocker arm will rotate around the pin, causing the other end of the rocker arm to move, thereby pulling the upper and lower magnetic locks and disengaging them from the upper and lower lock seats to achieve the unlocking operation. It is convenient to operate, stable and reliable to use, and has fewer overall structural parts, which helps to reduce processing costs. It is highly applicable and practical.

[0053] In practical applications, a horizontal support plate 9 is provided in the middle of the bottom wall of the pressing cavity, and a hollow round shaft 10 is fixed on the horizontal support plate; a pressing column 11 is integrally formed at the center of the bottom surface of the pressing plate; during use, the pressing plate passes through the return spring and can be raised and lowered inside the hollow round shaft. This structure ensures the smoothness and reliability of the pressing plate's raising and lowering, and the return spring provides strong practicality.

[0054] In this embodiment, the upper magnetic lock structure 1 includes a lock shell 1-1, a lock cover 1-2, a lock tongue shell 1-3, a first magnet block 1-4, a connecting block 1-5, and two locking rods 1-6. During installation, the lock cover and lock shell are fixed with screws. The lock tongue shell has a cavity 12 with an open end face and a locking slot 13. During installation, the first magnet block and the connecting block are both placed in the cavity and positioned in the locking slot by the locking rods. The end of the upper lever is connected to the connecting block for positioning. This structure improves the ease of installation and the stability and reliability of the lock tongue, making it highly practical.

[0055] In practical applications, the connecting block is provided with locking holes 14; the end of the upper lever is fixed with a locking cylinder 15 and a pressure spring 16; during installation, the pressure spring is sleeved on the end of the upper lever, and the locking cylinder is engaged in the locking holes for positioning, with the end of the pressure spring abutting against the end face of the connecting block. The locking cylinder improves the ease of installation, while the pressure spring facilitates reset during pressing operations, improving usability and stability.

[0056] In practical applications, the lower magnetic lock structure is the same as the upper magnetic lock structure.

[0057] Furthermore, to improve reliability, an upper locking seat 17 and a lower locking seat 18 with identical structures are also provided; magnetic locking cavities 19 are provided on the sides of the upper and lower locking seats; a second magnetic block 20 is locked inside the magnetic locking cavity. The second magnetic block is mainly used to cooperate with the first magnetic block to realize the magnetic locking operation.

[0058] In this embodiment, a pressure frame 21 is snapped and fixed to the top surface of the housing; both ends of the upper shaft are located within the vertical guide groove and the top end is limited by the pressure frame; the pressing plate is located within the pressure frame. This structure ensures the smooth pressing of the pressing plate and prevents the internal structure from loosening or falling off, making it highly practical.

[0059] The present invention has positive effects: The structure of the present invention is reasonably designed. By setting up an upper magnetic lock structure, a lower magnetic lock structure, a middle button assembly, an upper bar line, and a lower bar line, the locking operation is achieved through magnetic attraction, which improves the convenience of locking. At the same time, by using the middle button assembly in conjunction with the upper and lower bar lines, the upper and lower magnetic lock structures are unlocked by pressing, which improves the stability of use.

[0060] Furthermore, in this invention, the central button assembly includes a housing, a lower shaft, a pressing plate, a return spring, an upper shaft, two support rods, two rocker arms, and two pins. The upper and lower rocker arms are respectively screwed and fixed to the bottom ends of the two rocker arms. It can effectively realize the pressing control operation, and it is also easy to disassemble and assemble, which helps to improve the convenience and stability of disassembly and assembly, and has strong applicability and good practicality.

[0061] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
