The quick-mounting lock buckle is a connecting mechanism, which includes a buckle seat and a buckle. The buckle seat and the buckle are connected to the shoulder strap and the photography equipment respectively. Through the quick connection and disconnection of the buckle seat and the buckle, the quick connection and disconnection between the shoulder strap and the photography equipment are realized.

[0016] Reference Figure 1 and Figure 5As a quick mounting connecting mechanism provided by the embodiment of the application, the connecting seat 1, the locking assembly 2 and the connecting piece 3 are included. The connecting seat 1 includes a connecting head 11 and a movable sleeve 12. One end of the movable sleeve 12 is provided with an open end 121, and the other end is provided with a mounting position 122. The inside of the movable sleeve 12 is provided with a mounting cavity 123. The connecting head 11 extends into the mounting cavity 123 from the mounting position 122 and is slidingly connected to the movable sleeve 12. The locking assembly 2 includes a locking block 21, locking clamping arms 22 and a first suction accessory 23. The locking clamping arms 22 are at least two. The locking block 21 is located in the mounting cavity 123. The connecting head 11 is connected to the locking block 21. The locking clamping arms 22 are arranged close to the side wall of the mounting cavity 123. The locking clamping arms 22 are rotationally connected to the locking block 21. The locking clamping arms 22 are provided with locking grooves 24. The first suction accessory 23 is fixed on the locking block 21. The locking clamping arms 22 are arranged around the first suction accessory 23. The connecting piece 3 is provided with a second suction accessory 31. The second suction accessory 31 can be adsorbed to the first suction accessory 23 to drive the locking clamping arms 22 to rotate so that the connecting piece 3 is clamped and fixed in the locking groove 24.

[0017] The application discards the traditional pull rope unlocking mode and creatively uses magnetic attraction force as a driving source to automatically trigger mechanical clamping arms to lock. Once the connecting piece 3 is adsorbed and locked, it needs to overcome the combined action of magnetic attraction force and mechanical clamping force to be separated, and cannot be accidentally unlocked by simple straight pulling. It must be released by a specific pressing operation, which fundamentally avoids the risk of equipment falling caused by accidental pulling and significantly improves safety.

[0018] Specifically, the connecting seat 1 is mainly composed of the movable sleeve 12 and the connecting head 11. The movable sleeve 12 is a metal or high-strength plastic cylinder with two open ends. One end is an open end 121 for connecting the connecting piece 3, and the other end is a mounting position 122 provided with an opening. The connecting head 11 extends into the mounting cavity 123 from the mounting position 122 and is slidingly connected to the movable sleeve 12. The connecting head 11 and the mounting position 122 are provided with a limiting assembly, so that the connecting head 11 slides along the movable sleeve 12 and does not come off the movable sleeve 12. The inside of the movable sleeve 12 forms a mounting cavity 123.

[0019] In this embodiment, the first suction accessory 23 is fixed at the middle position of the locking block 21. The side wall of the locking block 21 is provided with a mounting groove 212. The locking clamping arms 22 are rotationally connected to the side wall of the mounting groove 212 through the setting of the rotating shaft 25. The two sides of the locking block 21 are symmetrically provided with the mounting groove 212. The locking clamping arms 22 are two and symmetrically arranged in the corresponding mounting grooves 212. The locking clamping arms 22 are rotationally connected to the locking block 21 through the rotating shaft 25.

[0020] Further, the locking clamping arms 22 include a clamping section 221 provided with a locking groove 24. The clamping section 221 can partially extend out of the open end 121 to open the locking groove 24.

[0021] Specifically, the locking clip arm 22 is generally long strip-shaped and can be divided into three sections, i.e., a clamping section 221, an intermediate section, and an abutting section 223. In the unlocked state, the clamping section 221 can partially extend out of the opening 121, so that the locking groove 24 is in an open posture, facilitating the entry of the connecting member 3. The end of the clamping section 221 close to the opening 121 is concave on the inner side (the side close to the first suction member 23) to form the locking groove 24, and the end of the outer side (the side away from the first suction member 23) is provided with a clamping block 222. When the clamping section 221 partially extends out of the opening 121, the clamping block 222 can be clamped to the inner side edge of the opening 121 or a specific clamping position, thereby temporarily limiting the locking clip arm 22 from retracting excessively. The intermediate section is the rotation center and is rotationally connected to the side wall of the mounting groove 212 through the rotation shaft 25. The abutting section 223 is arranged at the other end position, and the clamping section 221 and the abutting section 223 are respectively located at the two ends of the locking clip arm 22. The inner wall of the movable sleeve 12 is provided with a protruding abutting wall 124. When the clamping section 221 partially extends out of the opening 121, the abutting section 223 abuts against the abutting wall 124.

[0022] In order to be compatible with the two locking clip arms 22, two opposite protruding abutting walls 124 are arranged on the inner wall of the movable sleeve 12 at the side of the mounting cavity 123. The inner side (the side close to the center of the mounting cavity 123) of each abutting wall 124 is machined into an inclined guide surface 125. The inclination of the guide surface 125 forces the abutting section 223 to slide along the guide surface 125, so as to drive the clamping section 221 to rotate and retract into the mounting cavity 123, thereby achieving clamping of the connecting member 3.

[0023] Further, the locking assembly 2 further comprises an auxiliary elastic member 26. The movable sleeve 12 is provided with a support table 126. One end of the auxiliary elastic member 26 abuts against the support table 126, and the other end abuts against the connecting head 11. Pressing the connecting head 11 pushes the clamping section 221 to partially extend out of the opening 121, and the auxiliary elastic member 26 is squeezed and accumulates elastic force. The second suction member 31 is adsorbed to the first suction member 23 to drive the abutting section 223 to rotate, and the auxiliary elastic member 26 releases the elastic force to push the clamping section 221 to retract into the mounting cavity 123.

[0024] Specifically, in the installation cavity 123, near one end of the installation site 122, a support table 126 is arranged. The auxiliary elastic member 26 is preferably a compression spring, one end of which abuts against the support table 126, and the other end of which abuts against the connecting head 11 or a part connected with the connecting head 11. When the connecting head 11 is pressed to push the clamping section 221 to partially extend out of the opening 121, the inward movement of the connecting head 11 further compresses the auxiliary elastic member 26, so that the auxiliary elastic member 26 accumulates elastic potential energy. At this time, the clamping section 221 is in the open state, and the connecting member 3 is conveniently connected, which can be referred to the state diagram of Figure 3 and Figure 4 When the connecting member 3 is installed to the connecting seat 1, the second suction member 31 is adsorbed to the first suction member 23 and pushes the locking clamp arm 22 to rotate and fold, and in the process of rotating and folding, the abutting section 223 slides along the guide surface 125 into the installation cavity 123, at this time, the auxiliary elastic member 26 releases the accumulated elastic potential energy, pushes the connecting head 11 and the locking assembly 2 to quickly reset to the installation site 122 direction, so as to assist the clamping section 221 to be more tightly and quickly folded into the installation cavity 123 and complete the final locking.

[0025] The connecting head 11 is usually a cylindrical button, and a connecting hole 111 can be arranged at the top center for connecting an external back strap. The outer diameter of the connecting head 11 is slightly smaller than the inner diameter of the movable sleeve 12, so as to ensure smooth sliding. In order to facilitate the installation and positioning of the auxiliary elastic member 26, the locking block 21 is provided with a connecting column 211, the connecting head 11 extends into the installation cavity 123 from the installation site 122, the connecting head 11 and the connecting column 211 are connected by thread, buckle or interference fit, and the auxiliary elastic member 26 is sleeved on the connecting column 211. If the connecting member 3 is directly pulled without pressing the connecting head 11, the connecting member 3 has a tendency to move together with the locking block 21, but due to the existence of the auxiliary elastic member 26, the pulling force of the connecting member 3 is difficult to overcome the elastic force of the auxiliary elastic member 26, so that the connecting member 3 is stably fixed in the locking groove 24. When unlocking, the connecting head 11 can only be pressed to unlock.

[0026] By arranging the abutting wall 124 with the guide surface 125 and the auxiliary elastic member 26, the two actions of “pressing the connecting head 11, the locking clamp arm 22 is opened and ready to lock” and “magnetic adsorption, the locking clamp arm 22 is folded and locked” are perfectly connected. When releasing, pressing the connecting head 11 again can make the locking clamp arm 22 open and unlock.

[0027] Further, the first and second suction members 23 and 31 are both magnets, which can be neodymium iron boron magnets. The two suction surfaces are of different magnetic polarity, i.e. N pole vs. S pole. This achieves the quick connection process of "approaching to attract, attracting to lock". The user only needs to roughly align the connection piece 3 with the opening 121, and the magnetic force will guide the accurate alignment and automatically complete the complex mechanical locking action. The process is smooth, without the need for precise alignment or additional operations, greatly simplifying the connection steps and improving the use efficiency.

[0028] In other embodiments, the first and second suction members 23 and 31 can also be replaced by electromagnets or a combination of dissimilar metal materials that can be attracted to each other. The number of locking clamping arms 22 is not limited to two, but can also be three or more, uniformly distributed circumferentially.

[0029] The working principle and process of the quick installation connection mechanism in this embodiment are as follows: 1. Preparation / Release State: As shown in Figures 1 to 4 , in the initial state or after unlocking, the connection head 11 and the entire locking assembly 2 are pushed towards the opening 121 direction. At this time, the auxiliary elastic member 26 is compressed and accumulates elastic force. The clamping section 221 of the locking clamping arm 22 partially extends out of the opening 121. The clamping block 222 on the clamping section 221 is clamped on the edge of the opening 121 for limiting, and the abutting section 223 is abutted on the guide surface 125 of the abutting wall 124. The locking slot 24 is in an open state, and the first suction member 23 at the position of the opening 121 is exposed. The locking slot 24 is located at the front end position of the first suction member 23.

[0030] 2. Connection Process: As shown in Figures 5 to 8 , when connection is needed, the user sends the connection piece 3 with the second suction member 31 to the opening 121. When the second suction member 31 approaches the first suction member 23, under the action of the strong magnetic attraction of different poles, the magnetic force will quickly pull the two magnets close until they are tightly attracted. During this attraction process, since the second suction member 31 is fixed on the connection piece 3, and the first suction member 23 is fixed on the locking block 21, the front end of the connection piece 3 will first abut on the clamping section 221. Since the first and second suction members 23 and 31 are both cylindrical magnets, their end positions can be centered when they are attracted, which can enable the connection piece 3 to be accurately abutted on the side wall of the locking slot 24. During the rapid approach of the first and second suction members 23 and 31, a pushing force is applied to the clamping section 221, which promotes the rotation of the clamping section 221 and also promotes the movement of the locking block 21 towards the installation position 122.

[0031] When the connecting piece 3 is entering, its outer wall will contact the area of the opened locking slot 24. During the pushing process of magnetic adsorption, the continuous entering of the connecting piece 3 interacts with the inner side profile of the clamping section 221, the connecting piece 3 pushes the clamping section 221 to rotate around the rotating shaft 25, that is, the clamping section 221 starts to rotate and close to the center direction, at the same time, the auxiliary elastic member 26 which has accumulated elastic force also starts to release, pushing the connecting head 11 and the locking assembly 2 to reset to the direction of the mounting position 122, and the auxiliary elastic member 26 assists this closing process. When the two magnets are completely adsorbed in place, the clamping sections 221 of the two locking clamping arms 22 also rotate to the limit position, and the locking slots 24 on them are tightly clamped at the corresponding position of the connecting piece 3, as shown in Figure 7 、 8 . At this time, the connecting piece 3 is fixed by magnetic force and mechanical force, and is very firm. The abutting section 223 has been separated from the guide surface 125.

[0032] 3. Disassembly process: When it is necessary to disassemble the connecting piece 3, the user presses the connecting head 11, which drives the locking block 21 and the embedded first adsorption member 23 to move inside the mounting cavity 123 and slide towards the opening 121. When the clamping section 221 of the locking clamping arm 22 moves out of the opening 121, the connecting piece 3 can be pulled, and at this time, the part of the clamping section 221 that has moved out loses the limiting effect of the side wall. Under the action of the pulling force of the connecting piece 3, the second adsorption member 31 is separated from the first adsorption member 23, and at the same time, the end of the clamping section 221 is pulled to rotate, forcing the two clamping sections 221 to move away from the center, thereby realizing the opening of the locking slot 24, so that the locking slot 24 can be separated from the connecting piece 3. In the state that the magnetic force has been weakened and the mechanical clamping has been released, the user can easily pull out the connecting piece 3 from the opening 121, completing the disassembly.

[0033] In the rotating process of the clamping section 221, the abutting section 223 is a one-piece strip structure with the clamping section 221, and the abutting section 223 also rotates synchronously. After the abutting section 223 rotates, it starts to contact the abutting wall 124, and always contacts the abutting wall 124 in the subsequent rotating process. When the locking slot 24 is opened to the position, the clamping block 222 on the clamping section 221 is clamped to the side wall position of the opening 121, at this time, under the clamping action of the clamping block 222 and the abutting action of the abutting section 223, the locking assembly 2 is in a balanced state, and when it is not subjected to external force, the locking slot 24 is in an open state, facilitating the reconnection of the connecting piece 3.

[0034] The application discards the traditional pull rope unlocking mode, and creatively uses magnetic attraction as a driving source to automatically trigger the mechanical clamping arm to lock. Once the connecting piece 3 is adsorbed and locked, the magnetic attraction and the mechanical clamping force need to be overcome to separate the connecting piece 3, and the connecting piece 3 cannot be accidentally unlocked by simply pulling in a straight line. The connecting piece 3 must be released by a specific pressing operation, which fundamentally avoids the risk of equipment falling caused by accidental pulling and significantly improves safety.

[0035] The embodiments of the specific embodiment are the preferred embodiments of the application, but do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
