[0011] As a further improvement of the above technical solution, the base inner cavity of the base is provided with a first guide groove and a second guide groove to guide the buckle and the pressing piece respectively, the buckle is arranged in the first guide groove and can move in the first guide groove, and the pressing piece is arranged in the second guide groove and can move in the second guide groove.
[0012] As a further improvement of the above technical solution, the base inner cavity of the base is provided with two first guide plates, and the space between the two first guide plates forms the first guide groove; the base inner cavity of the base is provided with a second guide plate and a guide protrusion, and the space between the second guide plate and the guide protrusion forms the second guide groove.
[0013] As a further improvement of the above technical solution, the elastic reset piece includes a reset spring, the base inner cavity of the base is provided with a spring limiting plate, the inner end of the pressing piece is provided with a spring insertion part, one end of the reset spring abuts against the side wall of the spring limiting plate, and the other end of the reset spring is inserted into the spring insertion part of the pressing piece.
[0014] As a further improvement of the above technical solution, the base includes a base upper shell and a base lower shell, and the base upper shell and the base lower shell jointly form a U-shaped base, the U-shaped base has two extension parts, each extension part of the base is internally provided with independent long arm pieces, buckles, pressing pieces, and elastic reset pieces, and the long arm pieces, buckles, pressing pieces, and elastic reset pieces on the two extension parts are symmetrically arranged.
[0015] As a further improvement to the above technical solution, the base also includes a support frame and a base shell, wherein the support frame is fixedly installed on the base away from the pressing member through the base shell.
[0016] The beneficial effects of this invention are as follows: This invention provides a long-arm press-type buckle structure, which achieves the long-arm buckle function through a long-arm component, a buckle component, a pressing component, and an elastic reset component, and has the following advantages:
[0017] 1. Ease of operation: The long arm significantly increases the pressing stroke and reduces the operating force, making it easy to operate even in deep cavities and narrow spaces. This solves the problem of traditional buckles being "too hard to reach or press", improving the efficiency of equipment assembly and disassembly.
[0018] 2. Locking reliability: The precise locking structure and stable return spring ensure a firm connection after locking, resisting vibration and impact. It is suitable for product opening and closing and frequent equipment start-stop scenarios, reducing failures caused by loosening of the buckle and ensuring the stability of production and use.
[0019] 3. Structural adaptability: The symmetrical layout and modular design allow for adjustments to the long arm length, spring parameters, and locking structure based on equipment space and locking force requirements, adapting to various scenarios such as products, electronic equipment, and industrial cabinets, thus expanding the application scope.
[0020] 4. Durability: The material is made of wear-resistant and fatigue-resistant material. The spring has no significant attenuation during cyclic return. The hinge of the long arm is optimized (such as pin lubrication and wear-resistant coating). Under long-term high-frequency operation, the structure has a long service life and reduces maintenance and replacement costs.
[0021] In summary, this long-arm press-type buckle structure solves the technical defects of existing buckle structures, such as short operating stroke, difficulty in applying force in deep cavities or narrow spaces, difficulty in locking / unlocking, and the fact that the reliability of locking is greatly limited by the operating space, and is prone to buckle damage and connection failure due to uneven force application.

[0029] This invention provides:
[0030] A long-arm press-type buckle structure includes a base 1, the base 1 having an inner cavity and a long arm 2 disposed within the inner cavity, the long arm 2 being hinged within the inner cavity, a buckle 3 being disposed at a first end of the long arm 2 and having a buckle end 31 extending from the inner cavity of the base 1 to the outside of the base 1 for locking function, and a press member 4 being disposed at a second end of the long arm 2 and having a press end cap 41 extending from the inner cavity of the base 1 to the outside of the base 1 for locking function. Outside the base 1, an elastic reset member 5 is also provided in the inner cavity of the base. The elastic reset member 5 is used to drive the pressing end cap 41 of the pressing member 4 to always be in an outwardly extended state. Specifically, when the pressing end cap 41 is pressed, the pressing member 4 overcomes the reset elastic force of the elastic reset member 5 and drives the long arm member 2 to rotate around its hinge point. The latching end 31 retracts from the extended state into the base 1, thereby playing an unlocking function. When the pressing end cap 41 is not pressed, the latching end 31 of the latching member 3 is always extended outside the base 1, forming a latching effect. After pressing, due to the lever principle, the latching end 31 of the long arm member 2 retracts inward, which plays an unlocking role. Without pressing, the latching end 31 is in a latched state. In this embodiment, the base 1 is provided with a buckle end protrusion hole 102 adapted to the buckle end 31 of the buckle member 3, and the buckle end 31 can protrude from the buckle end protrusion hole 102; the base 1 is provided with an end cap protrusion hole 103 adapted to the pressing end cap 103 of the pressing member 4, and the pressing end cap 41 passes through the end cap protrusion hole 103 and extends to the outside of the base 1.
[0031] In a specific application of this invention, the elastic reset member 5 is fitted onto the inner end of the pressing member 4, and then the other end of the pressing member 4 (i.e., the pressing end cap 41) extends out from the corresponding circular hole in the base 1. When the pressing end cap 41 is pressed, the pressing end cap 41 drives the long arm member 2 to move inward, the elastic reset member 5 is compressed, and the long arm member 2 rotates around its hinge point. Under the action of the lever, the first end of the long arm 2 drives the locking unit (and locking end 31) of the buckle 3 to move away from the locking direction, which can realize the separation of the structure and realize the unlocking function. When it is necessary to lock, simply loosen the pressing end cover 41. Under the action of the reset spring of the elastic reset member 5, the elastic reset member 5 forms a reverse force on the pressing member 4 to push the pressing end cover 41 to move outward. The long arm 2 rotates in the opposite direction around the hinge point. Under the action of the lever, the first end of the long arm 2 drives the locking end 31 of the buckle 3 to move in the locking direction until the locking end 31 is engaged in the slot / interface (cc) of the adapter 6, thus completing the locking. The operation is convenient.
[0032] In this embodiment, the base 1 includes an upper base shell 11 and a lower base shell 12. The upper base shell 11 and the lower base shell 12 together form a U-shaped base. The U-shaped base 1 has two protruding parts 10.

The base 1 has a hinge shaft 101 adapted to the hinge hole 21 inside, the hinge shaft 101 extending into the hinge hole 21. The long arm 2 is hinged to the hinge shaft 101 through its hinge hole 21 and can rotate around the hinge shaft 101. In some other embodiments, a hinge shaft can be provided in the long arm 2, and a matching hinge hole can be provided inside the base 1. The specific positions of the hinge shaft and the hinge hole can be determined according to specific implementation requirements.

[0035] In some other embodiments, the buckle 3, the pressing member 4, and the long arm member 2 can also be configured as an integrally formed part.
[0036] In some embodiments, the base 1 has a first guide groove 104 and a second guide groove 105 in its base cavity, which respectively guide the snap fastener 31 and the pressing member 4. The snap fastener 31 is disposed in the first guide groove 104 and can move within the first guide groove 104, and the pressing member 4 is disposed in the second guide groove 105 and can move within the second guide groove 105. Specifically, the base 1 has two first guide plates 106 in its base cavity, and the space between the two first guide plates 106 forms the first guide groove 104. The base 1 also has a second guide plate 107 and a guide protrusion 108 in its base cavity, and the space between the second guide plate 107 and the guide protrusion 108 forms the second guide groove 105.
