Description

Technical Field

[0001] The utility model relates to the field of butterfly buckle structures, in particular to a split double-press butterfly buckle structure. Background Art

[0002] In the prior art, butterfly buckles, as a common connection device, are widely used in the field of detachable connections such as watch straps and backpack straps. Traditional butterfly buckles mostly adopt an integrated design, and their structure is relatively simple, but there are some inconveniences during use. Specifically, when a traditional butterfly buckle needs to be unlocked, the user usually needs to press the buttons on both sides at the same time. However, simply pressing the button is not enough to completely unlock the butterfly buckle. The user also needs to manually move the watch strap or buckle body after pressing the button to completely separate it. This unlocking method is relatively cumbersome, especially in emergency situations or when quick operation is required, which may cause inconvenience to the user. At the same time, due to its relatively fixed structure, once a component is damaged or fails, the entire butterfly buckle often needs to be replaced, which undoubtedly increases the cost of use and the difficulty of maintenance. Summary of the Invention

[0003] To address the aforementioned issues, the present invention provides a split, dual-press butterfly buckle structure. By incorporating a first elastic member and a second locking portion, the inner buckle automatically rebounds and disengages from its mounting space (i.e., automatically pops out) after the user pushes the button. This simplifies the unlocking process and improves operational efficiency. The relative independence of each component makes manufacturing and maintenance more flexible and convenient. If a component becomes damaged or fails, it can be replaced individually without having to replace the entire butterfly buckle.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a split double-press butterfly buckle structure, comprising two symmetrically arranged outer frames, and two inner guards movably arranged between the two outer frames, wherein one end of the inner guard is movably fitted in the fitting space between the two outer frames through a first elastic member, and a first snapping portion is provided at the other end of the inner guard, and a button is movably provided on the outer side of each outer frame, wherein one end of the button passes through the outer frame and is connected to a second locking portion; and the two second locking portions are connected by a second elastic member; wherein the first locking portion and the first snapping portion are disassembled by pushing the button, and the inner guard is detached from the fitting space under the action of the first elastic member.

[0005] Furthermore, the first elastic member includes a first rotating shaft and a torsion spring sleeved on the first rotating shaft, wherein the inner gear is mounted in the mounting space and the torsion spring is in a compressed state.

[0006] Furthermore, the first latch portion includes a first protrusion symmetrically arranged at the inner end, a locking channel arranged above the first protrusion, and a lock entry channel arranged between the two first protrusions, and the surfaces of the first protrusions close to each other are first inclined surfaces, and second protrusions are arranged on both sides of the first lock portion, and the second protrusion is provided with a second inclined surface matching the first inclined surface; the inner latch rotates and presses down around the first rotating shaft, so that the first inclined surface of the first protrusion squeezes the second inclined surface of the second protrusion, and at the same time forces the two first lock portions to approach each other; and the first lock portion moves to the lock entry channel, and the two first lock portions enter the locking channel under the action of the second elastic member.

[0007] Furthermore, the ends of the first locking portion are each provided with an elastic fitting groove, and the second elastic member is an ear pin, both ends of which are respectively clamped in the elastic fitting groove.

[0008] Furthermore, a button mounting slot and a first threading needle are provided on one side of the outer frame, wherein one end of the first threading needle is mounted on the button, and the other end of the first threading needle passes through the button mounting slot and is connected to the first locking portion.

[0009] Furthermore, a second filing needle is provided in the button assembly slot and is located on both sides of the first filing needle, and a positioning hole corresponding to the second filing needle is also provided at the end of the button.

[0010] Furthermore, a snap notch is provided below the inner frame, and a third filing needle for snapping into the snap notch is provided between the two outer frames.

[0011] The beneficial effect of the present invention is that the traditional butterfly buckle requires the user to press the buttons on both sides simultaneously and then manually turn the watchband or buckle body to fully unlock. However, by introducing the design of the first elastic member and the second locking part, the inner buckle can automatically rebound and disengage from the mounting space (i.e., automatically pop out) under the action of the first elastic member after the user pushes the button, thereby simplifying the unlocking process and improving operational efficiency. The traditional butterfly buckle unlocking process is cumbersome and may cause inconvenience to the user. However, by implementing the automatic unlocking function, the present technical solution allows users to complete the unlocking operation more quickly and conveniently, thereby enhancing the user experience.

[0012] The traditional one-piece butterfly buckle design results in high manufacturing and maintenance costs. However, the split, dual-press butterfly buckle structure of this technical solution offers greater flexibility and convenience in manufacturing and maintenance due to the relative independence of its components. If a component becomes damaged or ineffective, it can be replaced individually without having to replace the entire buckle. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1-7 As shown, the utility model relates to a split double-press butterfly buckle structure, comprising two symmetrically arranged outer frames 1, and two inner guards 2 movably arranged between the two outer frames 1, wherein one end of the inner guard 2 is movably fitted in the fitting space 4 between the two outer frames 1 through a first elastic member 3, and the other end of the inner guard 2 is provided with a first snap portion 21, and a button 5 is movably provided on the outer side of each outer frame 1, wherein one end of the button 5 passes through the outer frame 1 and is connected to a second locking portion 6; and the two second locking portions 6 are connected by a second elastic member; wherein the first locking portion and the first snap portion 21 are disassembled by pushing the button 5, and the inner guard 2 is separated from the fitting space 4 under the action of the first elastic member 3.

[0022] Furthermore, the first elastic member 3 includes a first rotating shaft and a torsion spring sleeved around the first rotating shaft. The inner rail 2 is mounted within the mounting space 4, and the torsion spring is compressed. When the inner rail 2 is locked, the torsion spring is compressed, providing stable support for the inner rail 2. At this point, the first latching portion 21 and the second locking portion 6 tightly mate, ensuring a secure connection between the watch strap and the inner rail. During the unlocking process, when the user pushes the button 5, the second locking portion 6 moves relative to the first locking portion, releasing their assembly. As the button 5 continues to be pushed, the inner rail 2 gradually rotates under the action of the first rotating shaft and the torsion spring and disengages from the mounting space 4, unlocking the watch strap. After unlocking, the torsion spring releases its stored energy, allowing the inner rail 2 to quickly return to its original position. During this process, the first rotating shaft plays a crucial supporting and guiding role, ensuring that the inner rail 2 moves smoothly and accurately returns to its original position. The elastic force of the torsion spring allows the inner rail 2 to quickly return to its original position after unlocking, providing a smoother and more convenient user experience.

[0023] Furthermore, the first latch portion 21 includes a first protrusion 211 symmetrically arranged at the end of the inner gear 2, a locking channel 212 arranged above the first protrusion 211, and a lock entry channel 213 arranged between the two first protrusions 211, and the surfaces of the first protrusions 211 close to each other are first inclined surfaces 214, and second protrusions 61 are arranged on both sides of the first lock portion, and the second protrusion 61 is provided with a second inclined surface 62 that cooperates with the first inclined surface 214; the inner buckle is rotated and pressed down around the first rotating shaft, so that the first inclined surface 214 of the first protrusion 211 squeezes the second inclined surface 62 of the second protrusion 61, and at the same time forces the two first lock portions to approach each other; and the first lock portion moves to the lock entry channel 213, and the two first lock portions enter the locking channel 212 under the action of the second elastic member.

[0024] The user operates the watch buckle by directly pressing down the two inner stops. This action causes the first inclined surface 214 of the first protrusion 211 on the first locking part to be squeezed with the second inclined surface 62 of the second protrusion 61. Due to this squeezing effect, the two first locking parts are forced to approach each other and move to the lock entry channel 213. Subsequently, the first locking part continues to press down, and the two first locking parts move further and enter the locking channel 212. At the same time, the second locking part 6 enters the locking channel 212 under the action of the second elastic member, forming a stable matching relationship with the first locking part. When the second locking part 6 completely enters the locking channel 212, the watch buckle is in a locked state, ensuring a stable connection of the watch strap.

[0025] Unlocking process: When the user needs to unlock the watch buckle, they push the buttons 5 on both sides again. This action causes the second locking portion 6 to begin moving, gradually leaving the locking channel 212 and entering the lock entry channel 213. At the same time, the first locking portion begins to rotate upward under the elastic force of the first rotating shaft and the torsion spring. As the second locking portion 6 continues to move, it eventually completely leaves the lock entry channel 213, at which point the first locking portion also returns to its initial position. Since the mating relationship between the first and second locking portions 6 is released, the watch buckle is now unlocked, and the user can easily detach the watch strap.

[0026] The beneficial effect is that the coordinated design of the first protrusion 211, the first inclined surface 214, the second protrusion 61, and the second inclined surface 62, along with the auxiliary function of the second elastic member, ensures extremely high stability when locked. This design effectively prevents the watch buckle from being accidentally unlocked by external forces. Furthermore, the user only needs to push the buttons 5 on both sides to unlock the watch buckle, making operation simple and labor-saving. Furthermore, the smooth movement of the first and second locking parts 6 also ensures a smooth unlocking process.

[0027] Furthermore, the ends of the first locking portion are each provided with an elastic fitting groove, and the second elastic member is an ear pin 74, both ends of which are respectively clamped in the elastic fitting groove.

[0028] The elastic fitting slots are an important component of the first locking part, and they are arranged at the ends of the first locking part. These slots are used to accommodate the insertion and fixation of the ear needles 74. Through this design, a firm connection between the ear needles 74 and the first locking part can be ensured, while facilitating the removal or replacement of the ear needles 74 when necessary. Moreover, as a common elastic connector, the ear needles 74 play a vital role in the split double-press butterfly buckle structure. It is used to connect two components that need to move relative to each other or maintain a certain distance. In this structure, the two ends of the ear needles 74 are respectively clamped in the elastic fitting slots of the two first locking parts. In this way, when the second locking part 6 (connected to the button 5) moves, the ear can be reset.

[0029] Moreover, compared to traditional springs, the ear pins 74 are less likely to permanently deform when subjected to force. This ensures the butterfly clasp maintains stable opening and closing force and performance over long-term use. Furthermore, replacing springs with ear pins 74 simplifies the butterfly clasp's internal structure, reducing the number of parts and assembly complexity, which helps lower production costs and improve efficiency.

[0030] Furthermore, a button fitting slot 11 and a first filing needle 71 are provided on one side of the outer frame 1, wherein one end of the first filing needle 71 is fitted with the button 5, and the other end of the first filing needle 71 passes through the button fitting slot 11 and is connected to the first locking portion.

[0031] The button fitting slot 11 is provided on one side of the outer frame 1 for accommodating and fixing the button 5. This design not only ensures the firm installation of the button 5, but also enables the user to easily find and push the button 5 during operation. The shape and size of the button fitting slot 11 match the button 5 to ensure a tight fit and smooth movement between them. The first filing needle 71 is a precision connector that acts as a bridge in the split double-press butterfly buckle structure. One end is fitted with the button 5 to ensure the stability and reliability of the button 5; the other end passes through the button fitting slot 11 and is tightly connected to the first locking part. Through this connection method, when the user pushes the button 5, the first filing needle 71 can accurately transfer force to the first locking part, thereby realizing the locking or unlocking function.

[0032] Furthermore, the button fitting slot 11 is provided with second filing needles 72 located on both sides of the first filing needle 71 , and the end of the button 5 is also provided with positioning holes 51 corresponding to the second filing needles 72 .

[0033] The second filing needles 72 are arranged in the button fitting slot 11, on both sides of the first filing needles 71. Together with the first filing needles 71, they constitute a stable connection system for fixing and supporting the button 5. At the end of the button 5, positioning holes 51 corresponding to the second filing needles 72 are provided. The shape and size of these positioning holes 51 are generally matched with the second filing needles 72 to ensure a close fit between them. When the user pushes the button 5, the second filing needles 72 will be inserted into these positioning holes 51, thereby further stabilizing the position of the button 5 and preventing it from shaking or falling off.

[0034] Furthermore, a snap notch 12 is provided below the inner rail 2, and a third file 73 is positioned between the two outer frames 1 to engage with the snap notch 12. The snap notch 12 and the third file 73 provide an additional stabilizing point when the watch buckle is locked, enhancing the overall structural stability. Their coordination does not aim for a tight clamping effect, but rather ensures that the inner rail 2 does not accidentally fall off or wobble when subjected to external forces. This design ensures the reliability of the watch buckle when locked while avoiding operational difficulties caused by overtightening.

[0035] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
