Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , a quick connection device for photographic equipment, including a quick connection mechanism and a clamping mechanism. The quick connection mechanism includes an outer shell 1. An installation groove 2 is opened inside the outer shell 1. A turntable 3 is arranged inside the installation groove 2. A first setting groove 4 is opened inside the turntable 3. An electric push rod 5 is fixedly installed inside the first setting groove 4. One end of the electric push rod 5 is fixedly connected to a moving block 6. A clamping frame 7 is fixedly connected to the upper side of the moving block 6. A pressure sensor 8 is fixedly installed inside the clamping frame 7. The pressure sensor 8 is electrically connected to the electric push rod 5. The turntable 3 is slidably connected to the installation groove 2. The moving block 6 is arranged inside the first setting groove 4 and is slidably connected to the first setting groove 4. When it is necessary to fix photographic equipment such as a camera on this connection device, place the photographic equipment at the position between the two clamping frames 7. The electric push rod 5 pushes the moving block 6 to slide inside the first setting groove 4 of the turntable 3. The moving block 6 drives the clamping frame 7 to move towards the photographic equipment until the photographic equipment is firmly clamped between the two clamping frames 7. After the pressure sensor 8 inside the clamping frame 7 senses the pressure of the photographic equipment, it transmits a signal to the electric push rod 5, causing the electric push rod 5 to stop, and enabling quick connection processing of the photographic equipment.

[0022] In one aspect of this embodiment, the turntable 3 is arranged inside the installation groove 2 of the outer shell 1 and is slidably connected to the installation groove 2, which enables the turntable 3 to freely rotate inside the installation groove 2. When it is necessary to adjust the shooting angle of the photographic equipment, the turntable 3 can be manually rotated. The turntable 3 drives the clamping frame 7 and the photographic equipment to rotate together, thereby realizing the shooting requirements at different angles. After adjusting the angle, the setscrew 9 can be screwed into the turntable 3 through the second setting groove 10, and the screwing end of the setscrew 9 is abutted against the upper surface of the outer shell 1, thereby fixing the turntable 3 inside the installation groove 2 to ensure that the angle of the photographic equipment does not change during the shooting process.

[0023] In one aspect of this embodiment, when it is necessary to fix the connecting device to the bracket, first place the connection part of the bracket at the position between the four clamping plates 14. A first rubber pad 15 is fixedly connected to the inner side of the clamping plate 14. On the one hand, it can increase the friction force to make the connection more firm. On the other hand, it can protect the connection part of the bracket and avoid scratching. The tension spring 12 inside the opening groove 11 generates a pulling force on the connecting block 13, and the connecting block 13 drives the clamping plate 14 to move towards the connection part of the bracket. Through the pulling force of the tension spring 12, the clamping plate 14 is tightly clamped outside the bracket connection, thereby realizing the rapid connection between the connecting device and the bracket.

[0024] In one aspect of this embodiment, when it is necessary to move the entire combination of the photographic equipment and the connecting device, or take it out from the storage position and place it at the shooting position, the user can operate by holding the handle 17. The position of the handle 17 is designed ergonomically to facilitate the application of force with both hands, making the process of taking and moving more labor-saving and convenient. During the use process, if the connecting device accidentally collides with other objects or is slightly impacted by external forces, the second rubber pad 16 can play a buffering role.

[0025] The working principle of the present utility model: When the quick connecting device for photographic equipment is in use, place the connection part of the bracket at the position between the four clamping plates 14. A first rubber pad 15 is fixedly connected to the inner side of the clamping plate 14. On the one hand, it can increase the friction force to make the connection more firm. On the other hand, it can protect the connection part of the bracket and avoid scratching. The tension spring 12 inside the opening groove 11 generates a pulling force on the connecting block 13, and the connecting block 13 drives the clamping plate 14 to move towards the connection part of the bracket. Through the pulling force of the tension spring 12, the clamping plate 14 is tightly clamped outside the bracket connection. Then, place the photographic equipment at the position between the two clamping frames 7. The electric push rod 5 pushes the moving block 6 to slide in the first setting groove 4 of the turntable 3, and the moving block 6 drives the clamping frame 7 to move towards the photographic equipment until the photographic equipment is firmly clamped between the two clamping frames 7. After the pressure sensor 8 inside the clamping frame 7 senses the pressure of the photographic equipment, it transmits a signal to the electric push rod 5 to make the electric push rod 5 stop, enabling rapid connection processing of the photographic equipment. When it is necessary to adjust the shooting angle of the photographic equipment, the turntable 3 can be manually rotated, and the turntable 3 drives the clamping frame 7 and the photographic equipment to rotate together, thereby realizing shooting requirements at different angles. After adjusting the angle, the top screw 9 can be screwed into the turntable 3 through the second setting groove 10, and the screwing end of the top screw 9 is abutted against the upper surface of the housing 1, thereby fixing the turntable 3 in the installation groove 2 to ensure that the angle of the photographic equipment does not change during the shooting process. All the electrical equipment in this solution is powered by a storage battery.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
