[0027] Exemplarily, a positioning groove 13 is provided in the mounting seat 1, and the first positioning member includes a first positioning rod 14 movably installed in the positioning groove 13, the positioning groove 13 is connected to the annular groove 12, one end of the first positioning rod 14 is located in the positioning groove 13, and the other end extends into the annular groove 12 and cooperates with the positioning hole. A mounting groove 11 is provided in the mounting seat 1, and a driving tube 4 is provided in the mounting groove 11. An opening 42 is provided at one end of the driving tube 4, and the opening 42 is connected to the outside of the mounting seat 1. A rotating plate 44 is provided at the opening 42 of the driving tube 4, and the rotating plate 44 is rotatably installed at the end of the driving tube 4. A connecting rod 43 is provided on the side of the first piston 41 close to the opening 42, and one end of the connecting rod 43 is hinged to the first piston 41, and the other end is hinged to the rotating plate 44. On the one hand, the rotating plate 44 can play a shielding role on the bayonet, and on the other hand, the rotating plate 44 is connected to the first piston 41 through the connecting rod 43. When the rotating plate 44 rotates, it can drive the first piston 41 to move in the horizontal direction, thereby driving the first piston 41.

[0028] Exemplarily, a limiting magnet 45 is provided at the end of the driving tube 4, and an iron sheet 46 cooperating with the limiting magnet 45 is provided on the rotating plate 44. When the limiting magnet 45 and the iron sheet 46 attract each other, the rotating plate 44 can be limited.

[0029] A first piston 41 is disposed in the driving tube 4, the first piston 41 abuts against the inner wall of the driving tube 4 and slides along the driving tube 4, and the first driving member includes a connecting tube connected to the driving tube 4 and a second piston 49 located in the connecting tube.

[0030] The driving tube 4 is connected to the connecting tube, and the first piston 41 and the second piston 49 are both movable. When the first piston 41 moves, the air pressure in the driving tube 4 and the connecting tube will be changed, and the air pressure will act on the second piston 49, so that the second piston 49 moves. In other words, when the first piston 41 moves, it will drive the second piston 49 to move, and when the second piston 49 moves, it will drive the first driving rod 15 to move. The first driving rod 15 is connected to the movable rod 16, so when the second piston 49 moves, it will drive the movable rod 16 to move. When the movable rod 16 moves, it will drive the first positioning rod 14 to move, so that the first positioning rod 14 and the first positioning hole 21 on the protective cover 2 are matched or separated. When the first positioning rod 14 and the first positioning hole 21 on the protective cover 2 are matched, the installation and positioning of the protective cover 2 is realized. When the first positioning rod 14 and the first positioning hole 21 are separated, it is convenient to disassemble the protective cover 2.

[0031] Exemplarily, a turntable 6 is provided in the mounting groove 11, and the turntable 6 is located below the driving tube 4. The bottom of the turntable 6 is rotatably connected to the mounting seat 1 through a rotating shaft. A curved arc groove 62 is provided at the bottom of the turntable 6. The bending direction of the arc groove 62 is gradually away from the center of the turntable 6 and bends toward the circumferential direction of the turntable 6. A clamping block 63 is provided in the arc groove 62. The clamping block 63 abuts against the inner wall of the arc groove 62 and can slide along the arc groove 62. The bottom of the clamping block 63 extends to the outside of the arc groove 62. The second positioning member includes a second positioning rod 64. The bottom of the clamping block 63 is connected to one end of the second positioning rod 64. A limiting plate 65 is provided in the mounting groove 11. The second positioning rod 64 passes through the limiting plate 65 and is movably connected to the limiting plate 65. The end of the second positioning rod 64 away from the center of the turntable 6 cooperates with the second positioning hole 32 to fix the plug-in board 31. The plug-in slot and the mounting slot 11 are connected to each other. After the plug-in board 31 is inserted into the plug-in slot, the top of the plug-in board 31 will be located in the mounting slot 11, so that the second positioning rod 64 and the second positioning hole 32 on the plug-in board 31 can cooperate with each other.

[0032] The turntable 6 is rotatably installed inside the mounting base 1, the arc groove 62 and the block 63 provided at the bottom of the turntable 6 cooperate with each other, the block 63 and the second positioning rod 64 cooperate with each other, the limit plate 65 in the mounting groove 11 cooperates with and limits the second positioning rod 64, when the turntable 6 rotates, the force is transmitted to the block 63 and the second positioning rod 64, because the second positioning rod 64 is limited, it can only slide in the horizontal direction, when the turntable 6 rotates forward, the second positioning rod 64 will be close to the plug-in board 31, so that it cooperates with the second positioning hole 32 on the plug-in board 31, when the turntable 6 rotates reversely, the second positioning rod 64 will be away from the plug-in board 31, at this time, the camera body 3 and the plug-in board 31 can be disassembled.

[0033] A first bevel gear 61 is provided on the top of the turntable 6, and a mounting plate 54 is provided at the bottom of the driving tube 4. A second bevel gear 55 is rotatably mounted on the mounting plate 54. The second bevel gear 55 meshes with the first bevel gear 61, and the axes of the second bevel gear 55 and the first bevel gear 61 coincide with each other.

[0034] The second driving member includes a movable block 5 disposed at the bottom of the driving tube 4 and a second driving rod 53 connected to the movable block 5. The movable block 5 is movably connected to the driving tube 4. A through hole matching the second driving rod 53 is disposed on the second bevel gear 55. The second driving rod 53 passes through the through hole and the mounting plate 54. A curved guide groove 56 is disposed on the second driving rod 53. A guide block 57 matching the guide groove 56 is disposed in the through hole. The guide groove 56 is curved. The bending direction of the guide groove 56 is along the length direction of the second driving rod 53 and bends toward the circumferential direction of the second driving rod 53. An inner magnet 51 is disposed on the first piston 41, and an outer magnet 52 is disposed on the movable block 5. The inner magnet 51 and the outer magnet 52 have opposite magnetic properties on the side where they are close to each other.

[0035] The inner magnet 51 is fixedly mounted on the first piston 41, and the outer magnet 52 is fixedly mounted on the movable block 5. The first piston 41 drives the movable block 5 through the inner magnet 51 and the outer magnet 52. When the first piston 41 moves, the outer magnet 52 and the movable block 5 are driven to move through the inner magnet 51. When the movable block 5 moves, the second driving rod 53 is driven to move. The guide groove 56 on the second driving rod 53 cooperates with the guide block 57 in the through hole to convert the horizontal moving force into the force for the second bevel gear 55 to rotate. When the second driving rod 53 moves, the second bevel gear 55 is driven to rotate. When the second bevel gear 55 rotates, the first bevel gear 61 is driven to rotate, thereby driving the turntable 6 to rotate. The rotation of the turntable 6 causes the second positioning rod 64 to move horizontally, thereby realizing the cooperation or separation of the second driving rod 53 and the second positioning hole 32 on the plug board 31. When the second positioning rod 64 and the second positioning hole 32 are separated, the plug board 31 and the camera body 3 can be disassembled.

[0036] The use principle of the embodiment of the present application is as follows: when installation is required, the rotating plate 44 is in an open state, first the plug-in plate 31 on the camera body 3 is inserted into the plug-in slot, and the rotating plate 44 is rotated to close it. When the rotating plate 44 is closed, the connecting rod 43 acts on the first piston 41 to move it. When the first piston 41 moves, the movable block 5 is driven to move through the inner magnet 51 and the outer magnet 52, and then the second driving rod 53 is driven to move. The second driving rod 53 acts on the through hole of the second bevel gear 55, and the guide groove 56 and the guide groove 56 are used to move the movable block 53. Block 57 causes the second bevel gear 55 to rotate. When the second bevel gear 55 rotates, it will drive the first bevel gear 61 to rotate, thereby realizing the rotation of the turntable 6. When the turntable 6 rotates, it will act on the second positioning rod 64 through the arc groove 62 and the bayonet. Because of the limitation of the limiting plate 65, the rotation force on the turntable 6 will be converted into a force for the horizontal movement of the second positioning rod 64, thereby causing the second positioning rod 64 to move horizontally. The end of the second positioning rod 64 cooperates with the second positioning hole 32 on the plug-in board 31 to realize the positioning of the plug-in board 31, thereby completing the installation of the camera body 3.

[0037] When the first piston 41 moves, the air pressure in the drive tube 4 and the connecting tube has been changed, but the end of the first positioning rod 14 has not yet matched with the first positioning hole 21. Continue to rotate the rotating plate 44 to make it completely closed. It should be noted that after the second positioning rod 64 and the plug-in plate 31 match, because the length of the arc groove 62 is limited, even if the turntable 6 is driven again, the second positioning rod 64 cannot continue to move. When the first piston 41 continues to move, because the movement of the movable block 5 is restricted, the inner magnet 51 and the outer magnet 52 will be temporarily separated, and the first piston 41 continues to move, but cannot drive the turntable 6 to continue to rotate. After this, the first piston 41 will continue to move and continue to change the air pressure in the connecting tube. The second piston 49 drives the first positioning rod 14 to move, and the end of the first positioning rod 14 matches with the first positioning hole 21 on the protective cover 2 to achieve the limit of the protective cover 2. At this point, the installation process is complete.

[0038] When disassembly is required, the rotating plate 44 is rotated to open it. When the rotating plate 44 moves, it drives the first piston 41 to move, changing the air pressure in the drive tube 4 and the connecting tube, so that the second piston 49 and the second positioning rod 64 move, so that the end of the second positioning rod 64 is separated from the protective cover 2, so that the protective cover 2 can be disassembled.

[0039] The rotating plate 44 continues to rotate, and the first piston 41 continues to move in the reverse direction. During this process, the inner magnet 51 on the first piston 41 and the outer magnet 52 on the movable block 5 cooperate again. When the first piston 41 moves in the reverse direction, it drives the second driving rod 53 to move in the reverse direction, drives the second bevel gear 55, the first bevel gear 61 and the turntable 6 to rotate, and the turntable 6 drives the second positioning rod 64 to move in the reverse direction. Finally, the second positioning rod 64 and the plug-in board 31 are separated, and the camera body 3 can be disassembled at this time. At this point, the disassembly process is completed.

[0040] Through the above process description, it can be seen that the present application has the effect of facilitating the installation and removal of the camera body 3 and the protective cover 2. In addition, because in conventional use, during the installation process, the camera body 3 is installed first and then the protective cover 2 is installed, and during removal, the protective cover 2 is removed first and then the camera body 3. The present embodiment of the present application can well fit the order of installation and removal through the above structure, and when in use, only the rotation of the rotating plate 44 is required to realize the positioning and removal of the protective cover 2 and the camera body 31, which is more convenient to use.

[0041] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
