Detailed Implementation

[0051] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0052] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0053] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a trigger-type locking device, including a housing 2 that is generally in the shape of a cover. A baffle 1 is installed on the top of the housing 2. The baffle 1 can be two relatively independent clamps or a rectangular enclosure structure. An installation groove 23 is provided below the baffle 1. A locking member 3 is movably installed in the installation groove 23. When the quick-release plate is inserted into the baffle 1, the locking member 3 swings relative to the quick-release plate under the pressure of the quick-release plate, and cooperates with the baffle 1 to clamp the quick-release plate.

[0054] Please see Figure 2 and Figure 3 The locking member 3 is generally hook-shaped. The locking member 3 includes a mounting part 31 and a clamping part 32 integrally formed with the mounting part 31. The clamping part 32 and the mounting part 31 have an included angle α, which is between 60 and 90 degrees. This allows the locking member 3 to swing and clamp the quick-release plate by slightly swinging the mounting part 31 under the pressure of the quick-release plate when the mounting part 31 is in a horizontal state.

[0055] Please see Figure 2 and Figure 3 The inner top wall of the housing 2 is provided with a movable groove 24 that communicates with the mounting groove 23. The mounting part 31 is integrally formed with a rotating shaft 34 that rotatably cooperates with the movable groove 24. The rotating shaft 34 is located at the connection between the mounting part 31 and the clamping part 32, so that the rotation center of the locking member 3 is rearward. When the mounting part 31 moves downward under the action of external force, the locking member 3 can swing relative to the baffle 1 to perform a clamping action through the cooperation of the rotating shaft 34 and the movable groove 24, thereby clamping the quick-release plate.

[0056] Please see Figure 1 and Figure 2 A trigger 35 is inserted into the top surface of the mounting part 31. The trigger 35 is located near the front end of the mounting part 31. The surface of the housing 2 has a through hole 25 for the trigger 35 to extend to the front of the baffle 1. When the quick-release plate is installed in the baffle 1, the trigger 35 is pressed downward. At this time, the trigger 35 automatically drives the locking member 3 to swing and enter the clamping state.

[0057] Please see Figure 3 and Figure 4 The mounting part 31 has a groove 9 on the bottom surface of its front end, and an elastic element A5 is installed in the groove 9. When the locking part 3 is not subjected to external force, the locking part 3 swings from the clamping state to the unlocking state under the force generated by the deformation of the elastic element A5.

[0058] Please see Figures 1 to 6The inner wall of the top center of the housing 2 protrudes downward to form a frustum 7. A locking member 4 is movably fitted around the frustum 7. The locking member 4 includes an operating part 41 and a locking part 42 integrally formed with the operating part 41. In this embodiment, the operating part 41 is generally in the form of an annular handle structure or other structure that can rotate around the frustum 7. The rotation center of the operating part 41 coincides with the center line of the frustum 7. A bearing can be installed between the operating part 41 and the frustum 7 to make the rotation of the operating part 41 smoother. A strip hole 21 is opened on the outer circumferential surface of the housing 2. The operating end of the operating part 41 extends out of the housing 2 through the strip hole 21.

[0059] The locking part 42 is located on the side of the operating part 41 near the locking member 3. The bottom surface of the locking part 42 is an inclined slope 43. The top surface of the mounting part 31 near the locking part 42 is recessed to form a stop surface 33. When the locking member 3 is pressed and swings to clamp the quick-release plate, the operating part 41 can be manually rotated clockwise to drive the locking part 42 to rotate above the locking member 3. During the process of the locking part 42 being rotated in, the inclined slope 43 gradually inserts into and cooperates with the stop surface 33 to press down the locking member 3, limiting the upper and lower positions of the locking member 3, thereby driving the locking member 3 to lock the quick-release plate. When the locking member 4 rotates counterclockwise, the locking part 42 separates from the stop surface 33 of the locking member 3, at which time the locking member 3 switches to the unlocked state.

[0060] Please see Figure 3 , Figure 5 and Figure 6 The housing 2 has a receiving groove 22 on its top inner wall, and the operating part 41 has a support lug 44. An elastic element B6 is installed between the support lug 44 and the end wall of the receiving groove 22. In this embodiment, the elastic element B6 is a spring.

[0061] Unlocking process: By rotating the operating part 41 counterclockwise, the operating part 41 causes the locking part 42 to separate from the locking member 3. At this time, the locking member 3 swings and releases the quick-release plate under the action of the elastic member A5. When the locking member swings, the mounting part 31 flips and rises. The locking part 42 abuts against the side of the locking member 3 under the force generated by the compression deformation of the elastic member B6. The locking member 3 switches from the clamping state to the unlocked state. Thus, by rotating the operating part 41 counterclockwise, the quick-release plate can be unlocked. The final unlocked state is as follows. Figure 2 As shown;

[0062] Clamping and locking process: When the quick-release plate is inserted, it presses against the trigger 35. The locking member 3 swings around the pivot 34 to clamp the quick-release plate. At this time, the stop surface 33 of the locking member 3 descends, and the locking member 3 disengages from the locking part 42. The locking member 4 is pushed to rotate clockwise to reset under the action of the elastic member B6 returning to its original state after compression deformation. The inclined surface 43 at the bottom of the locking part 42 inserts between the housing 2 and the stop surface 33, and cooperates with the stop surface 33 to press down the locking member 3, limiting its upper and lower positions so that the locking member 3 locks the quick-release plate. The final state is as follows. Figure 7 and Figure 8 As shown;

[0063] Secondly, when the locking force of the locking member 3 is insufficient, the operating part 41 can be manually rotated clockwise to further drive the locking part 42 to abut against the locking member 3, thereby increasing the force between the locking part 42 and the locking member 3, so that the locking member 3 locks the quick-release plate.

[0064] Please see Figure 1 , Figure 2 and Figure 4 A base plate 10 is fixedly connected to the bottom opening of the housing 2. The base plate 10 and the truncated cone 7 are respectively provided with mounting holes through the top and bottom. Bolts can be inserted through the mounting holes to fix the locking device of this utility model to the gimbal. The base plate 10 and the groove 9 are provided with the same groove, which is conducive to the installation of the elastic element A5.

[0065] The base plate 10 has a support column for supporting and assisting the rotation of the rotating shaft 34. The housing 2 is threadedly connected to a sleeve 11 on the side facing the base plate 10. An elastic element C12 is installed in the sleeve 11. In this embodiment, the elastic element is a spring. The other end of the elastic element C12 is fixedly connected to a pin 13. The surface of the housing 2 is provided with a through hole 26 for the pin 13 to extend to the front of the baffle 1.

[0066] During assembly, the quick-release plate presses the pin 13 downwards. Once the quick-release plate is in place, the pin 13 extends into the groove of the quick-release plate under the action of the elastic member C12. Even if the locking member 3 is loose, the quick-release plate will not slip out, providing a second layer of protection for the use of the camera.

[0067] Example 2: Please refer to Figure 9 and Figure 10Unlike Embodiment 1, the inner top wall of the housing 2 near the locking member 3 protrudes downward to form a cylinder 8. The side of the operating part 41 near the locking part 42 is rotatably connected to the cylinder 8. In this embodiment, the operating part 41 is a ring-shaped structure with a handle, or it can be a rod structure with an arched arc. The cylinder 8 and the locking part 42 form a resistance arm, and the cylinder 8 and the attachment point of the elastic member B6 on the locking member 4 form a power arm, forming a lever structure. When the operating part 41 is manually moved to swing and drive the locking part 42 closer to the locking member 3, the operating part 41 can be rotated with only a small force, so that the locking part 42 exerts a large force on the locking member 3 to lock the quick-release plate. It is also easier to move the locking part 42 to separate from the stop surface 33 and switch to the unlocked state.

[0068] In addition, in this embodiment, the elastic element B6 is a tension spring. When the operating part 41 is in the unlocked state, the elastic element B6 is in a stretched state, and the locking part 42 abuts against the side of the locking member 3. This allows the operating part 41 to swing under the pull of the elastic element B6 when the locking member 3 moves under the pressure of the quick-release plate. The inclined surface 43 of the locking part 42 abuts against the stop surface 33, thereby automatically locking the locking member 3. Furthermore, the lever structure allows the elastic element B6 to provide a large locking force for the locking part 42.

[0069] Please see Figure 11 This utility model also provides another technical solution: a photography kit, including a quick-release gimbal 14, wherein the quick-release gimbal 14 adopts the trigger-type locking device as described in Embodiment 1 or Embodiment 2 above, and the locking device is connected to the top of the universal ball 16 rod of the quick-release gimbal 14 by connecting bolt A15.

[0070] Please see Figure 12 and Figure 13 This utility model also provides another technical solution: a photography kit, including a dovetail quick-release adapter 17. The dovetail quick-release adapter 17 adopts a trigger-type locking device as described in Embodiment 1 or Embodiment 2 above. The housing 2 of the dovetail quick-release adapter 17 has two dovetail grooves in different directions. The top dovetail groove A171 is used to install a quick plate, and the side dovetail groove B172 is used to install on other photography equipment.

[0071] Please see Figure 14 and Figure 15The present invention also provides another technical solution: a photography kit, including a stabilizer quick-release adapter 18, wherein the stabilizer quick-release adapter 18 adopts the trigger-type locking device as described in Embodiment 1 or Embodiment 2 above, so that the stabilizer quick-release adapter 18 can quickly and conveniently lock the quick-release plate.

[0072] Please see Figure 16 and Figure 17 The present invention also provides another technical solution: including a threaded adapter 19, wherein the threaded adapter 19 adopts the trigger-type locking device as described in Embodiment 1 or Embodiment 2 above.
