DETAILED DESCRIPTION

[0026] The embodiments will be described in detail in conjunction with the drawings of the present application, and all other embodiments obtained by those skilled in the art without creative labor on the basis of the embodiments in the present application shall fall within the scope of protection of the present application.

[0027] Embodiment:

[0028] The utility model provides a quick release buckle, please refer to Figure 1 - Figure 6 The quick release buckle mainly comprises a separation assembly 1, a fixed assembly 2 and a locking mechanism. The fixed assembly 2 comprises a fixed seat 21 and a cover plate 23, which cooperate with each other to form a fixed part of the quick release buckle. The ring body 22 is clamped between the fixed seat 21 and the cover plate 23, providing a rotatable connection point for the quick release buckle and increasing the flexibility of use.

[0029] The separation assembly 1 is fixed with two groups of symmetrical first magnetic blocks 4 on the side opposite to the fixed assembly 2, and the fixed assembly 2 is fixed with two groups of second magnetic blocks 6 corresponding to the first magnetic blocks 4 inside. The second magnetic blocks 6 have magnetic attraction to the locking tongue 5, and the first magnetic blocks 4 and the second magnetic blocks 6 have magnetic attraction. The two groups of magnetic blocks cooperate with each other to play a preliminary positioning and attracting role before the quick release buckle is connected, facilitating subsequent locking operation.

[0030] The locking mechanism is the key part for realizing the connection and disconnection of the quick release buckle, which comprises a locking pin 12 fixed on the separation assembly 1 and a locking tongue 5 arranged in the fixed assembly 2. The locking pin 12 is provided with an annular locking groove 121, the side of the cover plate 23 opposite to the fixed seat 21 is provided with a locking tube 231, the fixed seat 21 is provided with a movable groove 212 corresponding to the locking tongue 5, the top of the locking tongue 5 is provided with a hanging rope 3, and the top of the movable groove 212 is further provided with a rope passing groove 213 matched with the hanging rope 3. Through the cooperative work of these components, the locking and unlocking functions of the quick release buckle are realized.

[0031] Further, the top of the separation assembly 1 is fixed with a first hanging ring 11, and the bottom of the ring body 22 is fixed with a second hanging ring 221. The first hanging ring 11 facilitates the connection of the quick release buckle with other objects, such as being hung on the shoulder strap, waistband, etc. of a backpack; the second hanging ring 221 can be used to connect other fixed objects, such as tent ropes, tools, etc. This double-hanging ring design greatly increases the flexibility and versatility of the quick release buckle.

[0032] The fixing seat 21 is fixed on the cover plate 23 by screws, which is simple and reliable, and can ensure the stable connection between the fixing seat 21 and the cover plate 23, and is not easy to loosen. The ring body 22 is rotationally connected between the fixing seat 21 and the cover plate 23, so that the ring body 22 can freely rotate within a certain angle range. This design enables the quick release buckle to better adapt to the stress direction when connecting objects in different directions, avoiding insecure connection or damage due to improper angle.

[0033] The fixing seat 21 is provided with a corresponding matching groove 211 corresponding to the lock pipe 231, and the lock pipe 231 is a half-round pipe structure with a cross-section C. This shape design provides sufficient space for the lock tongue 5 to move smoothly within the lock pipe 231, enabling the lock tongue 5 to lock and unlock the lock pin 12. It also ensures the stability of the structure and can withstand certain external forces without deforming. The top of the lock pipe 231 is in communication with the movable groove 212, so that the lock tongue 5 can freely shuttle between the lock pipe 231 and the movable groove 212 to complete the corresponding action.

[0034] Two groups of assembly grooves 232 are symmetrically provided on both sides of the lock pipe 231, which are specially used for fixing the second magnetic block 6. This design makes the installation position of the second magnetic block 6 accurate and stable, and can accurately correspond to the first magnetic block 4 on the separation assembly 1, so as to fully play the role of magnetic attraction. When the quick release buckle is connected, the magnetic attraction can quickly align the separation assembly 1 and the fixing assembly 2, reducing the operation time and difficulty and improving the connection efficiency.

[0035] The cover plate 23 opposite to the fixing seat 21 is also fixed with a baffle 233, and the main function of the baffle 233 is to block the upper port of the rope passing groove 213 and extrude the hanging rope 3 in the rope passing groove 213. This can effectively prevent the hanging rope 3 from accidentally coming out of the rope passing groove 213, and ensure the stability and reliability of the hanging rope 3 during use. At the same time, the extrusion of the baffle 233 to the hanging rope 3 also plays a certain fixing role, avoiding the hanging rope 3 from shaking randomly when not in use, affecting the normal use of the quick release buckle.

[0036] One side of the movable slot 212 is provided with a guide protrusion 2121, and one side of the lock tongue 5 is provided with a guide groove 52 matched with the guide protrusion 2121. This guide structure can ensure that the moving track of the lock tongue 5 in the movable slot 212 is accurate and smooth, avoiding the phenomenon of deviation, jamming or jamming of the lock tongue 5 during movement, and ensuring the normal operation of the quick release buckle. The side of the lock tongue 5 away from the hanging rope 3 is provided with an arc-shaped clamping groove 51, and the arc-shaped clamping groove 51 is designed to accurately match the annular locking groove 121 on the lock pin 12. When the lock pin 12 is inserted into the lock tube 231, the magnetic attraction force of the second magnetic block 6 on the lock tongue 5 is used to make the lock tongue 5 move downward and close to the lock pin 12, and then the arc-shaped clamping groove 51 can be accurately clamped into the annular locking groove 121 through the cooperation of the guide groove 52 and the guide protrusion 2121, so that the quick release buckle is locked. Moreover, the inner diameter of the arc-shaped clamping groove 51 is not less than the outer diameter of the annular locking groove 121, and this accurate size design ensures the close clamping between the lock tongue 5 and the lock pin 12, greatly improving the stability and reliability of the quick release buckle connection.

[0037] Connection process: when it is needed to connect the separated component 1 with the fixed component 2, first, the separated component 1 is close to the fixed component 2. Because of the magnetic attraction force between the first magnetic block 4 on the separated component 1 and the second magnetic block 6 in the fixed component 2, the separated component 1 will automatically approach and preliminarily align with the fixed component 2 under the action of the magnetic attraction force. This magnetic attraction force assisted positioning method greatly improves the accuracy and convenience of connection, and reduces the time and difficulty of manual adjustment.

[0038] Then, the lock pin 12 on the separated component 1 is inserted into the lock tube 231 on the fixed seat 21. With the gradual deepening of the lock pin 12, the lock tongue 5 in the lock tube 231 is extruded by the lock pin 12 and moves into the movable slot 212 by overcoming a certain resistance. In this process, the guide groove 52 on one side of the lock tongue 5 moves along the guide protrusion 2121 on one side of the movable slot 212, ensuring that the direction of the lock tongue 5 movement is accurate.

[0039] When the annular locking groove 121 on the lock pin 12 moves to the position aligned with the arc-shaped clamping groove 51 on the lock tongue 5, the lock tongue 5 is quickly clamped into the annular locking groove 121 under the magnetic attraction force of the second magnetic block 6. At this time, the quick release buckle completes the locking process, and the separated component 1 and the fixed component 2 are firmly connected together and can withstand a certain pulling force and external force, meeting the connection requirements in actual use.

[0040] Disassembly process: when the quick release buckle needs to be disassembled, the operator pulls the hanging rope 3. The hanging rope 3 is connected to the top of the lock tongue 5, and pulling the hanging rope 3 will make the lock tongue 5 move upward in the movable slot 212. Because of the cooperation of the guide protrusion 2121 and the guide groove 52, the moving direction of the lock tongue 5 can be accurately controlled and deviation or jamming will not occur.

[0041] With the upward movement of the locking tongue 5, the arc-shaped clamping slot 51 gradually disengages from the annular locking slot 121. When the arc-shaped clamping slot 51 completely disengages from the annular locking slot 121, the locking pin 12 is no longer clamped by the locking tongue 5. At this time, the operator can easily pull the separation assembly 1 from the fixed assembly 2, completing the disassembly process of the quick-release buckle.

[0042] Regarding the assembly method of the quick-release buckle:

[0043] Magnetic block installation: First, carefully install the second magnetic block 6 in the assembly groove 232 on both sides of the locking tube 232. During installation, ensure that the polarity of the magnetic block is correct and firmly installed to avoid loose or magnetic interference. Appropriate glue or fixing device can be used to fix the magnetic block in the assembly groove to ensure that it does not move during use.

[0044] Locking tongue installation: Place the locking tongue 5 smoothly into the movable slot 212 of the fixed seat 21. When placing, ensure that the guide slot 52 on one side of the locking tongue 5 precisely matches the guide protrusion 2121 on one side of the movable slot 212, so that the locking tongue 5 can move smoothly up and down in the movable slot 212. The locking tongue 5 can be manually pushed to check if it moves smoothly. If there is any jamming or discomfort, adjust the position of the locking tongue 5 or the movable slot 212 in time.

[0045] Rope connection: Thread one end of the hanging rope 3 through the rope threading slot 213, and then firmly connect it to the top of the locking tongue 5. The connection method can use knotting, buckling, etc. to ensure that the hanging rope 3 is firmly connected to the locking tongue 5 and not easily detached. After the connection is completed, fix the baffle 233 on the cover plate 23 to block the upper port of the rope threading slot 213, and appropriately press the hanging rope 3 in the rope threading slot 213 to prevent it from coming out.

[0046] Ring body installation: Install the ring body 22 between the fixed seat 21 and the cover plate 23, so that the ring body 22 can freely rotate between them. A suitable amount of lubricant can be applied to the contact parts of the ring body 22, the fixed seat 21 and the cover plate 23 to reduce friction during rotation and ensure the flexibility of the ring body 22 rotation.

[0047] Fixed seat and cover plate fixation: Fix the fixed seat 21 and the cover plate 23 by screws. When tightening the screws, pay attention to uniform force to ensure that the fixed seat 21 and the cover plate 23 are tightly connected and do not loosen or shake.

[0048] Separation assembly assembly: Firmly fix the locking pin 12 on the separation assembly 1 to ensure that the position of the locking pin 12 is accurate and does not deviate. Then, install two sets of symmetrical first magnetic blocks 4 on the side of the separation assembly 1 relative to the fixed assembly 2. During installation, ensure that the first magnetic blocks 4 accurately correspond to the second magnetic blocks 6 in the fixed assembly 2 to achieve good magnetic attraction effect.

[0049] Use of quick release buckle:

[0050] Connection operation: When connection is needed, separate component 1 is close to fixed component 2. Due to the action of magnetic attraction, separate component 1 will automatically approach fixed component 2 and preliminarily align. Then, lock pin 12 on separate component 1 is slowly inserted into lock tube 231 on fixed seat 21 until it is felt that lock tongue 5 is clamped into annular lock groove 121, at which time the quick release buckle completes connection, and the connection state is stable and reliable.

[0051] Disassembly operation: When the quick release buckle needs to be disassembled, pull the hanging rope 3 gently to make the lock tongue 5 move upward and disengage from the annular lock groove 121. During the process of pulling the hanging rope 3, attention should be paid to uniform force to avoid excessive force causing damage to the hanging rope 3 or deformation of the lock tongue 5. When the lock tongue 5 completely disengages from the annular lock groove 121, separate component 1 can be easily pulled out of fixed component 2, completing the disassembly process.

[0052] Maintenance of quick release buckle:

[0053] Regular inspection: Regularly check the quick release buckle for wear, deformation, damage or looseness of each component. Key components such as lock tongue 5, lock pin 12, magnetic block and hanging rope 3 are checked. For severely worn or damaged components, replace them in time to ensure normal use of the quick release buckle.

[0054] Cleaning and maintenance: Keep the quick release buckle clean to avoid dust, debris and other foreign matter entering key parts such as lock tube 231 and movable groove 212. Clean the surface and interior of the quick release buckle with a clean cloth or brush to remove dirt and impurities. Avoid strong magnetic fields or impacts on the magnetic block to affect its magnetic properties.

[0055] Hanging rope maintenance: Regularly check the condition of the hanging rope 3. If signs of wear, breakage or aging are found, replace the hanging rope in time. Ensure that the length of the hanging rope 3 is moderate, convenient to operate and not too long to affect use or cause safety hazards.

[0056] The quick release buckle preliminarily positions through magnetic attraction, and then cooperates with the quick clamping design of the lock tongue and lock pin to make the connection and disassembly operation extremely simple. Users do not need to use any tools, just need to perform simple plug-in and pull actions to complete the connection and disassembly of the quick release buckle in a short time, greatly improving the use efficiency and meeting the user's demand for quick operation.

[0057] The precise matching of the locking tongue 5 and the locking pin 12, and the close engagement of the arc-shaped clamping groove 51 and the annular locking groove 121, ensure that the quick release buckle can withstand greater pulling force and external force in the connected state, and is not easy to loosen or fall off. At the same time, the auxiliary role of magnetic attraction further enhances the stability of the connection, so that the quick release buckle can maintain a reliable connection state in various complex environments and use conditions, providing higher safety protection for users.

[0058] The design of the first hanging ring 11 on the separation assembly 1 and the second hanging ring 221 at the bottom of the ring body 22 makes the quick release buckle can be conveniently connected with various different articles, whether it is a backpack, a tent, a tool or other equipment, can be easily adapted. Such versatility not only reduces the user's trouble of preparing multiple connection buckles for different connection needs, but also reduces the use cost, improves the practicability and market competitiveness of the product.

[0059] The overall structure of the quick release buckle is simple and clear, the functions of each component are clear, and they cooperate closely. Common connection methods such as screw fixation and rotary connection are used, making the assembly and maintenance of the quick release buckle more convenient. At the same time, appropriate materials are selected to manufacture each component, ensuring that the quick release buckle has high strength and durability, can withstand long-term use and various environmental conditions, and reduces the waste of resources and increase in cost caused by frequent replacement of connection buckles.

[0060] In summary, the quick release buckle of the utility model solves the problems existing in the prior art through unique structure design and working principle, has the advantages of simple operation, stable connection, strong versatility, simple structure, durability and the like, and has a wide application prospect.

[0061] The above describes only the best implementation mode adopted by the present application in combination with the current actual demand, but the protection scope of the present application is not limited thereto.
