[0003] Existing quick-release buckles are either too complex in structure, making installation and disassembly cumbersome and time-consuming; or too simple, consisting only of a sliding groove and a stop structure, which makes it easy for the two fasteners to come loose accidentally during use, thus hindering stability. Summary of the Invention

[0004] This invention provides a quick-release buckle that improves the convenience of installation and disassembly, and ensures stability during use.

[0005] This invention discloses a quick-release buckle, comprising: a first buckle and a second buckle; the first buckle and the second buckle are magnetically connected; the first buckle has a receiving groove, and a snap-fit ​​structure is formed between the first buckle and the second buckle; the bottom of the receiving groove and one of the second buckles are provided with a positioning groove, and the other is provided with a positioning protrusion; when the second buckle is received in the receiving groove, it can be snapped into place by the snap-fit ​​structure, and the positioning protrusion can be held in the positioning groove; the first buckle is also provided with an unlocking mechanism, which, when activated, pushes one side of the second buckle away from the first buckle, thereby releasing the snap-fit ​​structure from the snap-fit ​​state.

[0006] Optionally, the snap-fit ​​structure includes a snap-fit ​​portion disposed at one end of the second fastener, and a protruding edge disposed on one side of the receiving groove and extending inward, wherein the snap-fit ​​portion can snap into the protruding edge.

[0007] Optionally, the first fastener has a receiving groove on the side opposite to the receiving groove, and the bottom of the receiving groove has a through hole communicating with the receiving groove; the unlocking mechanism includes a pusher disposed in the receiving groove, the pusher is provided with a protrusion, and the protrusion can pass through the through hole to lift the second fastener.

[0008] Optionally, the pusher is further provided with a connecting part, and a connecting shaft is connected to the connecting part. The two ends of the connecting shaft are respectively connected to the opposite sides of the receiving groove. A reset structure is also provided between the pusher and the first fastener. A limiting protrusion is provided at the end of the pusher away from the connecting part, and a limiting groove is provided on the side edge of the receiving groove. The limiting protrusion can be engaged with the limiting groove.

[0009] Optionally, the pushing member is slidably connected to the receiving groove, and a reset structure is also provided between the pushing member and the first fastener. A limiting platform is provided on the side edge of the receiving groove, and the side of the pushing member can be engaged with the limiting platform.

[0010] Optionally, the reset structure is an elastic element, or the reset structure is a magnet with magnetic poles facing each other respectively disposed on the pusher and the first fastener.

[0011] Optionally, when the first fastener and the second fastener are engaged by the snap-fit ​​structure, there is a preset distance between the side of the receiving groove away from the snap-fit ​​structure and the second fastener.

[0012] Optionally, the first fastener has an opening and a through groove at opposite ends, the through groove being used to connect the first connecting strap, the second fastener being able to connect the second connecting strap, and the second connecting strap being able to pass through the first fastener through the opening.

[0013] Optionally, the first fastener is provided with a first groove, and the first groove is located at the bottom of the receiving groove. The second fastener is provided with a second groove. A first magnetic element is provided in the first groove, and a second magnetic element is provided in the second groove. The first magnetic element and the second magnetic element can be magnetically attracted to each other.

[0014] Optionally, the second fastener is wedge-shaped, and the thickness of the side of the second fastener with the retaining portion is less than the thickness of the other side.

[0015] The beneficial effects of the quick-release buckle provided in this invention are as follows: When the first and second fasteners are snapped together, the magnetic connection between them allows for automatic adsorption and positioning, eliminating the need for manual alignment and reducing installation difficulty. Simultaneously, the cooperation of the positioning groove and the positioning protrusion forms a double-limiting mechanism, ensuring a stable snap-fit ​​between the first and second fasteners. Under the action of the snap-fit ​​structure, it can withstand a certain amount of tensile and impact forces, preventing accidental separation of the first and second fasteners. Furthermore, the cooperation of the positioning groove and the positioning protrusion further restricts the displacement of the second fastener within the receiving groove, ensuring the stability of the snap-fit ​​structure and reducing the risk of items falling (such as a camera) due to loosening. When it is necessary to separate the first and second fasteners, simply activating the unlocking mechanism pushes one side of the second fastener away from the first fastener, causing the positioning groove and positioning protrusion to disengage, thus quickly releasing the snap-fit ​​structure. The entire unlocking process requires no complex operation. By adopting the above method, the ease of installation and disassembly can be improved, while ensuring stability during use.

Detailed Implementation

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 5 As shown, this embodiment of the invention provides a quick-release buckle 100, including: a first buckle 110 and a second buckle 120; the first buckle 110 and the second buckle 120 can be magnetically connected; the first buckle 110 has a receiving groove 112, and a snap-fit ​​structure 130 is formed between the first buckle 110 and the second buckle 120; the bottom of the receiving groove 112 and one of the second buckle 120 are provided with a positioning groove 122, and the other is provided with a positioning protrusion 114; when the second buckle 120 is received in the receiving groove 112, it can be snapped together by the snap-fit ​​structure 130, and the positioning protrusion 114 can be held in the positioning groove 122; the first buckle 110 is also provided with an unlocking mechanism 140, when the unlocking mechanism 140 is activated, one side of the second buckle 120 can be pushed away from the first buckle 110, thereby releasing the snap-fit ​​structure 130 from the snap-fit ​​state.

[0021] Specifically, the first fastener 110 and the second fastener 120 can be magnetically connected. This magnetic connection allows for quick positioning of the first fastener 110 and the second fastener 120 during initial docking, while also enhancing the fit after connection and preventing misalignment during docking. The first fastener 110 has a receiving groove 112, the size of which is adapted to accommodate the second fastener 120, ensuring a compact fit and reducing overall size. This is suitable for applications requiring miniaturized accessories, such as cameras and backpacks. Simultaneously, a snap-fit ​​structure 130 is formed between the first fastener 110 and the second fastener 120, facilitating stable connection and limiting the weight and impact of hanging objects such as cameras, preventing the second fastener 120 from detaching from the first fastener 110 under pulling or impact forces. The bottom of the receiving groove 112 and the second fastener 120 are provided with a positioning groove 122 on one side and a positioning protrusion 114 on the other side. Alternatively, the receiving groove 112 may have a positioning groove 122 at the bottom and the second fastener 120 may have a positioning protrusion 114; or the receiving groove 112 may have a positioning protrusion 114 at the bottom and the second fastener 120 may have a positioning groove 122. When the second fastener 120 is received in the receiving groove 112, the positioning protrusion 114 can be held in place within the positioning groove 122, preventing the second fastener 120 from wobbling left or right or shifting forward or backward within the receiving groove 112. This ensures the stability of the locking structure 130. When it is necessary to release the latching state of the latching structure 130, the unlocking mechanism 140 can be activated. After activation, the unlocking mechanism 140 can push one side of the second fastener 120 away from the first fastener 110, causing the positioning protrusion 114 to disengage from the positioning groove 122, thereby releasing the latching structure 130 from the latching state, so as to achieve rapid separation of the first fastener 110 and the second fastener 120.

[0022] The quick-release buckle 100 provided in this embodiment of the application allows the first buckle 110 and the second buckle 120 to be automatically engaged and positioned by magnetic attraction, eliminating the need for manual alignment and reducing the difficulty of installation. Simultaneously, the cooperation between the positioning groove 122 and the positioning protrusion 114 forms a double-limiting mechanism with the snap-fit ​​structure 130, ensuring a stable engagement between the first buckle 110 and the second buckle 120. The snap-fit ​​structure 130 can withstand a certain amount of tension and impact, preventing accidental separation of the first buckle 110 and the second buckle 120. Furthermore, the cooperation between the positioning groove 122 and the positioning protrusion 114 further restricts the displacement of the second buckle 120 within the receiving groove 112, ensuring the stability of the engagement at the snap-fit ​​structure 130 and reducing the risk of items falling (such as a camera) due to loosening. When it is necessary to separate the first fastener 110 and the second fastener 120, simply activate the unlocking mechanism 140 to push one side of the second fastener 120 away from the first fastener 110. This causes the positioning groove 122 and the positioning protrusion 114 to disengage, thereby quickly releasing the locking structure 130 from its locking state. The entire unlocking process requires no complicated operation. This design improves the convenience of installation and disassembly while ensuring stability during use.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the snap-fit ​​structure 130 includes a snap-fit ​​portion 132 disposed at one end of the second fastener 120, and a protruding edge 134 disposed on one side of the receiving groove 112 and extending inward, wherein the snap-fit ​​portion 132 can snap into the protruding edge 134.

[0024] Specifically, the retaining part 132 can be integrally formed with the second fastener 120, and the protruding edge 134 can be integrally formed with the first fastener 110, eliminating the need for additional connecting parts or complex components. This simplifies the production process and reduces processing difficulty and manufacturing costs. Furthermore, the retaining part 132 can be simply designed as a boss, and the protruding edge 134 can cooperate with the bottom of the receiving groove 116 to limit the opposite sides of the retaining part 132 in the thickness direction. The sidewall of the receiving groove 116 can limit the corresponding side of the retaining part 132, thereby enabling the engaging surfaces of the retaining part 132 and the protruding edge 134 to form a stable limit and withstand greater tensile force. Moreover, the engaging form of the above-mentioned engaging structure 130 is relatively simple, facilitating subsequent separation of the engaged state.

[0025] like Figure 6 and Figure 7As shown, the first fastener 110 has a receiving groove 116 on the side opposite to the receiving groove 112, and the bottom of the receiving groove 116 has a through hole 117 communicating with the receiving groove 112; the unlocking mechanism 140 includes a pusher 142 disposed in the receiving groove 116, and a protrusion 143 is disposed on the pusher 142, which can pass through the through hole 117 to push up the second fastener 120.

[0026] Specifically, the first fastener 110 has a receiving groove 116 on the side opposite to the receiving groove 112, which hides the pusher 142 inside the first fastener 110, preventing it from protruding from the surface of the first fastener 110, reducing the risk of accidental activation, and making the overall structure of the quick-release buckle 100 more compact. The bottom of the receiving groove 116 has a through hole 117 communicating with the receiving groove 112. The size of the through hole 117 is adapted to the protrusion 143 on the pusher 142, providing a channel for the movement of the protrusion 143 and ensuring that the protrusion 143 can pass through the through hole 117 to act on the second fastener 120. In practical applications, the pusher 142 is the core trigger component of the unlocking mechanism 140, and its shape is adapted to the receiving groove 116, allowing it to move within the receiving groove 116. The protrusion 143 provided on the pusher 142 can be integrally formed with the pusher 142. The position of the protrusion 143 corresponds to the through hole 117. When the pusher 142 is touched (such as pressing the pusher 142), the pusher 142 drives the protrusion 143 to move downward (towards the receiving groove 112). After the protrusion 143 passes through the through hole 117, it pushes up one side of the second fastener 120, causing the second fastener 120 to tilt, thereby causing the positioning groove 122 and the positioning protrusion 114 to ensure that the holding part 132 can disengage from the protrusion 134 and achieve unlocking.

[0027] like Figure 6 , Figure 7 and Figure 8 As shown, the pusher 142 is also provided with a connecting part 144, and a connecting shaft 145 is connected to the connecting part 144. The two ends of the connecting shaft 145 are respectively connected to the opposite sides of the receiving groove 116. A reset structure 146 is also provided between the pusher 142 and the first fastener 110. A limiting protrusion 147 is provided at the end of the pusher 142 away from the connecting part 144. A limiting groove 118 is provided on the side edge of the receiving groove 116. The limiting protrusion 147 can be engaged with the limiting groove 118.

[0028] Specifically, the connecting part 144 is an extension structure on the push member 142, used to connect with the connecting shaft 145. Both ends of the connecting shaft 145 are connected to opposite sides of the receiving groove 116, allowing the push member 142 to be rotatably connected to the first fastener 110 via the connecting shaft 145. A reset structure 146 is also provided between the push member 142 and the first fastener 110. The function of the reset structure 146 is to restore the push member 142 to its initial position after the unlocking operation is completed, facilitating the next unlocking operation. A limiting protrusion 147 is provided at the end of the push member 142 away from the connecting part 144, and a limiting groove 118 is provided on the side edge of the receiving groove 116. The size of the limiting protrusion 147 and the limiting groove 118 are adapted to each other. When the push member 142 is in the initial position, the limiting protrusion 147 can be engaged with one side wall of the limiting groove 118 to limit the initial position of the push member 142 and prevent the push member 142 from shaking or rotating accidentally in the unlocked state. When the push member 142 is pressed and rotated, the limiting protrusion 147 can deflect away from the engaged position to ensure normal unlocking of the quick release buckle 100.

[0029] In another optional embodiment of this application, the pusher 142 is slidably connected to the receiving groove 116, and a reset structure 146 is also provided between the pusher 142 and the first fastener 110. A limiting platform is provided on the side edge of the receiving groove 116, and the side of the pusher 142 can be engaged with the limiting platform.

[0030] Specifically, the pusher 142 is slidably connected to the receiving groove 116, meaning the pusher 142 can slide along the depth direction of the receiving groove 116. A reset structure 146 is also provided between the pusher 142 and the first fastener 110. The function of the reset structure 146 is to restore the pusher 142 to its initial position after the unlocking action is completed, facilitating the next unlocking operation. The limiting platform can be engaged with the side edge of the receiving groove 116, or connected by fasteners such as screws, so that the side of the pusher 142 can be held by the limiting platform, preventing the pusher 142 from disengaging from the receiving groove 116 under the action of the reset structure 146.

[0031] In an optional embodiment of this application, the reset structure 146 is an elastic element, or the reset structure 146 is a magnet with opposing magnetic poles respectively disposed on the push member 142 and the first fastener 110.

[0032] Specifically, when the reset structure 146 is an elastic element, the elastic element can be a spring, installed between the push member 142 and the first fastener 110 (e.g., one end of the spring is connected to the push member 142, and the other end is connected to the bottom of the receiving groove 116). When the push member 142 is touched (rotated or slid), the elastic element deforms (e.g., is compressed), storing elastic potential energy; when the user releases the push member 142, the elastic element releases the elastic potential energy, pushing the push member 142 back to its initial position, thus achieving automatic reset. The elastic element can be directly fitted onto the protrusion 143 to restrict its free movement, which helps ensure the reliability of the connection.

[0033] When the reset structure 146 consists of magnets with opposite magnetic poles respectively disposed on the push member 142 and the first fastener 110, that is, one magnet is disposed on the push member 142 and another magnet is disposed at the corresponding position on the first fastener 110, and the magnetic poles of the two magnets are opposite (like poles opposite), the reset is achieved by utilizing the principle of like poles repulsion; when the push member 142 is touched, the distance between the two magnets decreases and the repulsive force increases; when the user releases the push member 142, under the action of magnetic force, the push member 142 is pushed back to the initial position, realizing automatic reset.

[0034] like Figure 1 As shown, when the first fastener 110 and the second fastener 120 are engaged by the snap-fit ​​structure 130, there is a preset distance d between the side of the receiving groove 112 away from the snap-fit ​​structure 130 and the second fastener 120.

[0035] Specifically, the preset gap d refers to the gap between one side of the receiving groove 112 (the side away from the receiving structure 130) and the corresponding side of the second fastener 120 when the first fastener 110 and the second fastener 120 are in a snap-fit ​​state through the snap-fit ​​structure 130. This gap can be designed according to actual unlocking requirements, such as 1mm-2mm. By setting the preset gap d, the side of the second fastener 120 away from the snap-fit ​​structure 130 has room to move, which makes it easier for the second fastener 120 to have a certain amount of room to move after being placed into the receiving groove 112 of the first fastener 110. This allows the positioning protrusion 114 and the positioning groove 122 to quickly align and fit together under the magnetic attraction of the first fastener 110 and the second fastener 120, thus ensuring the rapid and stable snap-fit ​​engagement of the first fastener 110 and the second fastener 120 through the snap-fit ​​structure 130. Similarly, by setting a preset gap d, when the unlocking mechanism 140 pushes the second fastener 120 away from the snap-fit ​​structure 130, the second fastener 120 can tilt smoothly, thereby releasing the positioning protrusion 114 and the positioning groove 122 from the snap-fit. On this basis, the second fastener 120 can move laterally so that the snap-fit ​​part 132 and the protrusion 134 are disengaged from the snap-fit ​​state.

[0036] like Figure 1 and Figure 2 As shown, the first fastener 110 has an opening 113 and a through groove 115 at its opposite ends. The through groove 115 is used to connect the first connecting strap. The second fastener 120 can connect the second connecting strap 160, and the second connecting strap 160 can pass through the first fastener 110 through the opening 113.

[0037] Specifically, the second connecting strap 160 connected to the second fastener 120 can pass through the first fastener 110 through the opening 113 on the first fastener 110, making the arrangement of the second connecting strap 160 more reasonable, smoother, and neater, facilitating connection with motor equipment such as cameras, and improving the user experience. The through-slot 115 is used to fix the first connecting strap, ensuring a firm connection that can withstand a certain amount of tension, preventing the first connecting strap from falling off the first fastener 110, thereby improving the reliability of the connection.

[0038] like Figure 4 and Figure 9 As shown, the first fastener 110 is provided with a first groove 1122, and the first groove 1122 is located at the bottom of the receiving groove 112. The second fastener 120 is provided with a second groove 124. A first magnetic element 1124 is provided in the first groove 1122, and a second magnetic element 126 is provided in the second groove 124. The first magnetic element 1124 and the second magnetic element 126 can be magnetically attracted.

[0039] Specifically, the first fastener 110 has a first groove 1122 located at the bottom of the receiving groove 112. The size of the first groove 1122 is adapted to accommodate the first magnetic component 1124. The second fastener 120 has a second groove 124 adapted to accommodate the second magnetic component 126. The first groove 1122 contains the first magnetic component 1124, and the second groove 124 contains the second magnetic component 126. Both the first magnetic component 1124 and the second magnetic component 126 can be magnets, or one can be a magnetic conductor and the other a magnet, thereby achieving a magnetic connection between the first fastener 110 and the second fastener 120. In addition, to avoid direct exposure of the first magnetic component 1124 and the second magnetic component 126, a first shielding pad 1126 can be attached to the corresponding position of the first magnetic component 1124. And attach the second shielding pad 128 to the corresponding position of the second magnetic component 126.

[0040] like Figure 3 As shown, the second fastener 120 is wedge-shaped, and the thickness of the side of the second fastener 120 with the holding part 132 is smaller than the thickness of the other side.

[0041] Specifically, the thickness of the wedge-shaped structure, i.e., the second fastener 120, gradually changes from one end to the other, forming an inclined side. The side with the retaining portion 132 (the side that engages with the protrusion 134) is thinner, while the other side (the side away from the retaining portion 132) is thicker. This facilitates the smooth engagement of the retaining portion 132 with the corresponding position on the protrusion 134. Furthermore, the wedge-shaped structure allows the second fastener 120 to move easily away from the engaging structure 130 for quick separation. It is understandable that anti-slip textures 129 can be provided on the second fastener 120 to improve ease of movement and prevent the smoothness of the second fastener 120 from increasing the difficulty of separating it from the first fastener 110.

[0042] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of the present invention.
