[0026] Embodiment:

[0027] As Figures 1-4As shown, a spring buckle mechanism with a sliding key includes a bottom shell 100; the bottom shell 100 is provided with a key 110; the key 110 is connected with a push plate 111; the push plate 111 and the bottom shell 100 are provided with a first reset spring 120; the end of the push plate 111 away from the key 110 is provided with a first inclined surface 112; the first inclined surface 112 cooperates with a counterpart 130; the push plate 111 can move close to or away from the counterpart 130; the counterpart 130 is provided with an inclined block 131 cooperating with the first inclined surface 112; the counterpart 130 is rotationally connected with the bottom shell 100; the counterpart 130 is connected with a second reset spring 140; the second reset spring 140 acts on the counterpart 130 to make the inclined block 131 have a tendency to approach the first inclined surface 112.

[0028] The push plate 111 and the counterpart 130 cooperate through the first inclined surface 112 and the inclined block 131, and utilize the inclined surface sliding principle to realize force transmission and direction conversion. This design reduces frictional resistance, making operation smoother. The inclined surface cooperation structure is relatively uniform in stress during relative movement, reducing local stress concentration. The two reset springs reasonably share the reset force, reducing the pressure borne by individual components. Uniform stress distribution and reasonable reset force sharing reduce the degree of wear of each component during movement. Compared with traditional spring buckle mechanisms, the spring buckle mechanism with the sliding key 110 has a slower wear rate of each component, thereby prolonging the service life of the entire spring buckle mechanism and improving the reliability and economy of the product. At the same time, the first reset spring 120 (acting on the push plate 111) and the second reset spring 140 (acting on the counterpart 130) form a double reset mechanism: the former directly pushes the push plate 111 to reset, and the latter maintains the tightness of the inclined surface contact through the inclined block 131, ensuring the continuity and sensitivity of the reset action. This synergistic effect significantly improves the reset response speed, avoiding the reset delay caused by friction or jamming in traditional single-spring mechanisms;

[0029] The movement trajectory of the push plate 111 is constrained by the limiting design of the bottom shell 100, preventing the key 110 from deviating or being stuck, and reducing the dependence on processing precision. In an embodiment, the continuous pressure of the second reset spring 140 makes the inclined block 131 always tightly adhere to the first inclined surface 112, avoiding impact wear caused by gaps. In an embodiment, the continuous pressure of the second reset spring 140 makes the inclined block 131 have a tendency to approach the first inclined surface 112, and the bottom of the inclined block 131 can not contact the first inclined surface 112. Only when the first inclined surface 112 moves towards the inclined block 131, and after contacting the inclined block 131, the continuous pressure of the second reset spring 140 makes the inclined block 131 tightly adhere to the first inclined surface 112.

[0030] The direct connection of the button 110 and the push plate 111 simplifies the operation steps, and the user only needs to press in one direction to trigger the mechanism. The sliding fit of the push plate 111 and the counter 130 realizes force amplification effect through the inclined surface, reducing the force required for operation. The independent reset path of the double springs (horizontal reset of the push plate 111 and rotary reset of the counter 130) avoids the problem of mutual interference of multiple components in the traditional linkage structure, improving the action reliability.

[0031] The bottom shell 100 serves as an integrated carrier, modularly assembling the button 110, the push plate 111, the spring, etc. (such as the through hole and the fixing lug design), facilitating disassembly, maintenance or replacement of single components. At the same time, the independent setting of the spring (non-nested type) reduces the assembly difficulty, and when damaged, there is no need for overall replacement.

[0032] In an embodiment, the push plate 111 is provided with a limiting groove 114; the bottom shell 100 is provided with a guide column 103 matched with the limiting groove 114. The cooperation of the limiting groove 114 and the guide column 103 can accurately control the sliding stroke of the push plate 111, avoiding mechanism jamming or part damage caused by out-of-range movement. When the user pushes the button 110 to drive the push plate 111 to move, the push plate 111 can only move along the path defined by the guide column 103, ensuring the stable and accurate movement trajectory of the push plate 111. In this way, the first inclined surface 112 on the push plate 111 can accurately cooperate with the inclined block 131 on the opponent piece 130, avoiding the deviation or shaking of the push plate 111 during movement, ensuring that the action of the pop buckle mechanism can be accurately performed according to the design requirements, and improving the movement accuracy of the entire mechanism. The accurate movement trajectory helps to maintain the stable transmission relationship between the push plate 111 and the opponent piece 130. During the working process of the pop buckle mechanism, the cooperation of the push plate 111 and the opponent piece 130 is the key to realizing the pop buckle function. Through the guiding action of the guide column 103 and the limiting groove 114, the push plate 111 can stably transmit the pushing force of the button 110 to the opponent piece 130, so that the opponent piece 130 rotates as expected, thereby realizing the unlocking or locking function of the pop buckle, ensuring the stability and reliability of the mechanism transmission. The cooperation of the limiting groove 114 and the guide column 103 limits the freedom of the push plate 111 in other directions, so that the push plate 111 can only move linearly in a specific direction. This effectively prevents unnecessary shaking or tilting of the push plate 111 during movement, enhancing the installation stability of the push plate 111 in the bottom shell 100. The stable movement of the push plate 111 also helps to maintain the structural stability of the entire pop buckle mechanism, reducing the problems of mechanism loosening or damage that may be caused by the shaking of the push plate 111. During the movement of the push plate 111, the contact between the guide column 103 and the limiting groove 114 can disperse the force borne by the push plate 111. When the button 110 pushes the push plate 111, the force is not only transmitted through the push plate 111 itself, but also dispersed through the cooperation of the guide column 103 and the limiting groove 114, avoiding the case that the local force of the push plate 111 is too large.

[0033] In an embodiment, the top of the guide column 103 is fixedly connected with a limiting screw 104. The limiting screw 104 forms a limiting structure at the top of the guide column 103. The push plate 111 is sleeved on the guide column 103 to slide through the limiting groove 114. When the push plate 111 reaches the top limit position of the guide column 103 during movement, the limiting screw 104 can block the push plate 111 from moving upward, thereby preventing the push plate 111 from being detached from the guide column 103. The limiting screw 104 further limits the freedom of the push plate 111 in the vertical direction. When the push plate 111 slides along the guide column 103, the limiting screw 104 can reduce the shaking and swinging of the push plate 111 near the top of the guide column 103, making the movement of the push plate 111 more stable.

[0034] In an embodiment, the push plate 111 is provided with a connecting portion 115 matched with the first reset spring 120; one end of the first reset spring 120 away from the connecting portion 115 abuts against the side wall of the bottom shell 100; the push plate 111 is provided with a through observation hole 116 opposite to the connecting portion 115. The connecting portion 115 provided on the push plate 111 provides a precise installation position for the first reset spring 120. The connecting portion 115 can be a groove 113, a protrusion or other specific structure, which can be tightly matched with the end of the first reset spring 120, so that the spring is accurately installed on the push plate 111. In this way, during the working process of the buckle mechanism, the spring can stably follow the movement of the push plate 111, avoiding the displacement or falling off of the spring on the push plate 111, and ensuring the normal play of the spring reset function. The through observation hole 116 provided on the push plate 111 is opposite to the connecting portion 115, through which the operator can directly observe the state of the first reset spring 120. During the use of the buckle mechanism, the spring may be fatigued, deformed or damaged due to frequent compression and expansion. Through the observation hole 116, without disassembling the buckle mechanism, it can be found in time whether the spring is abnormal, such as whether the spring is broken, whether it is deformed too much, etc., so as to take measures such as replacement or repair in time, and ensure the normal operation of the buckle mechanism. During installation, it is also convenient for the installation of the first reset spring 120.

[0035] In an embodiment, the bottom of the inclined block 131 is formed with a second inclined surface 132 matched with the first inclined surface 112; a plurality of grooves 113 are arranged on one side of the first inclined surface 112 opposite to the second inclined surface 132 to reduce the contact area with the second inclined surface 132, so that the push plate 111 moves more smoothly when moving close to or away from the opponent tool 130, and is not easy to be stuck.

[0036] In an embodiment, the bottom of the inclined block 131 is formed with an arc surface matched with the first inclined surface 112. The arc surface matched with the inclined surface reduces the concentrated wear of the contact surface, prolonging the service life.

[0037] In an embodiment, the counter 130 is provided with a connecting cylinder 133; the second reset spring 140 is arranged in the connecting cylinder 133; the part of the second reset spring 140 extending out of the connecting cylinder 133 abuts against the face shell 101; and the face shell 101 is fixedly connected with the bottom shell 100 by a fixing screw 102. The connecting cylinder 133 on the counter 130 provides a precise mounting position and guide for the second reset spring 140. The spring is arranged in the connecting cylinder 133, and its extension direction is limited by the connecting cylinder 133, so that the spring can be compressed and extended along a predetermined direction, avoiding bending, twisting or deviation of the spring during operation, ensuring that the elastic force of the spring can accurately act on the counter 130, so that the counter 130 rotates and resets according to the design requirements, ensuring the stability and accuracy of the reset action of the snap mechanism. The connecting cylinder 133 can prevent the second reset spring 140 from falling off the counter 130 during movement. The face shell 101 provides a stable support point for the spring. When the counter 130 rotates, the spring is compressed to store elastic potential energy; when the external force disappears, the spring releases the elastic potential energy, and through the support action of the face shell 101, the reset force is accurately transmitted to the counter 130, so that the counter 130 can quickly and stably reset to the initial position, ensuring the reset sensitivity of the snap mechanism.

[0038] In an embodiment, the counter 130 is provided with an extension arm 134; and the end of the extension arm 134 away from the counter 130 is rotationally connected with the bottom shell 100 by a rotating shaft 135. The rotating shaft 135 provides a precise rotation center for the counter 130. The extension arm 134 forms a certain distance between the counter 130 and the rotating shaft 135, and when the inclined block 131 of the push plate 111 cooperates with the counter 130 to push the counter 130 to move, the counter 130 can stably and accurately rotate around the rotating shaft 135. The structural design of the extension arm 134 helps to reduce friction and jamming during rotation. Since the extension arm 134 properly separates the force point of the counter 130 from the rotation center, the force arm of the counter 130 during rotation is more reasonable, and the rotation action can be completed more smoothly. Compared with the structure without the extension arm 134, this design can reduce the force required during rotation, making the operation more comfortable and improving the user experience.

[0039] In an embodiment, two extension arms 134 are arranged on one side of the opponent piece 130, and the distance between the two extension arms 134 gradually increases in the direction away from the opponent piece 130. The two extension arms 134 provide double-point support for the opponent piece 130, which can better constrain the rotation of the opponent piece 130 and make the rotation more stable. When the inclined block 131 on the opponent piece 130 is pushed by the push plate 111 to rotate around the rotation shaft 135, the two extension arms 134 can jointly bear the external force, reduce the shaking and deviation of the opponent piece 130, and ensure the accuracy of the rotation. This is crucial for the unlocking and locking functions of the elastic buckle mechanism, and can improve the working reliability and accuracy of the mechanism. As the distance between the two extension arms 134 gradually increases in the direction away from the opponent piece 130, a relatively stable support structure is formed. This structure can enhance the anti-torsion capability of the opponent piece 130. When the opponent piece 130 is subjected to a torsion force, the two extension arms 134 can jointly resist the torsion, prevent the opponent piece 130 from being damaged or affecting its normal rotation due to the torsion, and further improve the stability and durability of the elastic buckle mechanism.

[0040] In an embodiment, the distance between the connecting cylinder 133 and the extension arm 134 is greater than the distance between the inclined block 131 and the extension arm 134. When the inclined block 131 is pushed by the push plate 111 to rotate around the rotation shaft 135 at the end of the extension arm 134, the second return spring 140 is installed in the connecting cylinder 133, and the action point of the return force generated by the second return spring 140 on the opponent piece 130 is relatively far from the rotation shaft 135. The larger force arm makes the return torque generated by the second return spring 140 larger. This means that under the same spring force, the opponent piece 130 can obtain greater return power, so as to be more quickly and stably returned to the initial position, and the sensitivity and reliability of the return of the elastic buckle mechanism are improved. The action point of the pushing force of the push plate 111 on the inclined block 131 is closer to the extension arm 134, and the action point of the return force of the second return spring 140 is farther from the extension arm 134. This layout helps to achieve better force balance during the rotation of the opponent piece 130. When the inclined block 131 is pushed by the push plate 111 to rotate the opponent piece 130, the reverse torque generated by the return spring can effectively balance the torque generated by the pushing force, reduce the shaking and deviation of the opponent piece 130 during the rotation, make the rotation process more stable, and ensure the working accuracy of the elastic buckle mechanism.
