[0023] As Figures 1 to 6As shown, the lens quick connection structure of the camera waterproof shell provided by the embodiment comprises a lens 1, a camera waterproof shell 2 and a connecting piece 3. The lens 1 is provided with at least two clamping protrusions 4 at the port. The camera waterproof shell 2 is provided with a ring groove 5 at the periphery of the window. The connecting piece 3 is provided with an avoidance hole 6 at the center for avoiding blocking the viewfinder line of sight. One end surface of the connecting piece 3 is provided with a butt joint groove 7. The butt joint groove 7 is provided with a corresponding number of L-shaped clamping grooves 8. The clamping protrusions 4 are inserted into the clamping grooves 8 and locked by rotating. The other end surface of the connecting piece 3 is provided with a first stop block 9 and a second stop block 10 at the adjacent edges of the avoidance hole 6. The connecting piece 3 is provided with a hinged seat 11 at the opposite side of the second stop block 10. The hinged seat 11 is hingedly connected with a locking block 12. The other end of the locking block 12 is provided with a plug-in plug 13. The outer end surface of the second stop block 10 is provided with a plug hole 14. The inner end surfaces of the first stop block 9, the second stop block 10, the hinged seat 11 and the locking block 12 are provided with rib strips 15 which can be clamped into the ring groove 5. The locking block 12 is rotated at the hinge point on the hinged seat 11 so that the plug 13 can be placed in the plug hole 14. After the plug 13 is inserted into the plug hole 14, the locking block 12 is inhibited from rotating.

[0024] The embodiment selects to abandon the traditional thread butt joint and relies on the rotating mode of the buckle to make the butt joint of the lens more quick. At the same time, a connecting piece 3 is added as an intermediate member and combined with the rib strips 15 to plug into the ring groove 5 along the periphery. After the locking between the plug 13 of the locking block 12 and the plug hole 14, the connection and locking between the camera waterproof shell 2 are realized. The whole can avoid the lengthening treatment at the window of the camera waterproof shell 2 so that the normal use of the camera waterproof shell 2 will not be affected after the whole is disassembled.

[0025] When assembling, the connecting piece 3 and the camera waterproof shell 2 can be assembled first. When the connecting piece 3 and the camera waterproof shell 2 are assembled, the locking block 12 is first in the open state. At this time, the area surrounded by the first stop block 9, the second stop block 10, the hinged seat 11 and the locking block 12 is opened. The opened port can accommodate the window of the camera waterproof shell 2. Therefore, the user only needs to push the window of the camera waterproof shell 2 into the port after the locking block 12 is opened. With the window of the camera waterproof shell 2 being pushed in, the ring groove 5 will be plugged into the corresponding rib strip 15. When the window cannot be pushed any more, the locking block 12 is only rotated back to embed the rib strip 15 of the locking block 12 into the ring groove 5 and insert the plug 13 into the plug hole 14. In this way, the assembly between the connecting piece 3 and the camera waterproof shell 2 is completed. The assembly between the connecting piece 3 and the lens 1 can be quickly completed by aligning and rotating the clamping protrusions 4 and the clamping grooves 8. Whether it is disassembled or replaced with another lens, the operation will be very simple.

[0026] Further, in order to meet the requirement of assembly stability of the lens, at least two circular clamping holes 16 are arranged on the same side of the lens 1 where the clamping protrusion 4 is arranged, and a spring ball 17 is arranged on the end face of the connecting piece 3 towards the lens 1, and after the clamping protrusion 4 is inserted into the clamping groove 8, the ball of the spring ball 17 is locked in the clamping hole 16. Thus, when the lens 1 is locked by the clamping protrusion 4 and the clamping groove 8, it is also locked by the spring ball 17, so that the locking of the clamping protrusion 4 and the clamping groove 8 is firm, and the phenomenon of automatic disengagement of the lens 1 does not occur.

[0027] Further, because it is used underwater, water is easy to enter the inside of the spring ball 17 in repeated movement of the spring ball 17, and in order to avoid water accumulation in the spring ball 17, a drain hole 100 is arranged on the side of the connecting piece 3, which is in communication with the inside of the spring ball 17, so that when there is water in the spring ball 17, the water inside can be drained through the drain hole, avoiding water accumulation.

[0028] Further, in order to avoid the operation of the bolt 13 during assembly, the bolt 13 is automatically locked, and in order to achieve the plug-in connection of the bolt 13, it can be threaded or directly pushed by elastic force, and here in order to avoid the operation of the bolt 13 during assembly, the bolt 13 is automatically locked, so that the locking block 12 is arranged with a through cavity 18 on the other end connected to the hinge seat 11, the bolt 13 is arranged in the through cavity 18, and the one end of the bolt 13 is arranged with a top cap 19 outside the through cavity 18, the minimum diameter of the top cap 19 is greater than the diameter of the through cavity 18, the other end of the bolt 13 is located at the inner end of the through cavity 18, the bolt 13 is arranged with a baffle 20 and a spring 21, one end of the spring 21 is in contact with the inner wall of the through cavity 18, the other end of the spring 21 is in contact with the baffle 20, and under the action of the spring 21, the bolt 13 is always arranged outside the through cavity 18 relative to the other end of the end head provided with the top cap 19. Thus, when the locking block 12 is screwed, the bolt 13 will first retreat when it touches the second stop block 10, and then the bolt 13 will be inserted into the bolt hole 14 under the reset action of the spring 21 after being aligned with the bolt hole 14, and the automatic locking is completed, and when unlocking is needed, the bolt 13 can be separated from the bolt hole 14 by holding the top cap 19 and pulling it outwards, achieving the purpose of unlocking, and the overall operation is very simple in structure and steps, which is beneficial to the user to quickly operate.

[0029] Further, in order to avoid the operation of the bolt 13 during assembly, the bolt 13 is automatically locked, and in order to achieve the plug-in connection of the bolt 13, it can be threaded or directly pushed by elastic force, and here in order to avoid the operation of the bolt 13 during assembly, the bolt 13 is automatically locked, so that the locking block 12 is arranged with a through cavity 18 on the other end connected to the hinge seat 11, the bolt 13 is arranged in the through cavity 18, and the one end of the bolt 13 is arranged with a top cap 19 outside the through cavity 18, the minimum diameter of the top cap 19 is greater than the diameter of the through cavity 18, the other end of the bolt 13 is located at the inner end of the through cavity 18, the bolt 13 is arranged with a baffle 20 and a spring 21, one end of the spring 21 is in contact with the inner wall of the through cavity 18, the other end of the spring 21 is in contact with the baffle 20, and under the action of the spring 21, the bolt 13 is always arranged outside the through cavity 18 relative to the other end of the end head provided with the top cap 19. Thus, when the locking block 12 is screwed, the bolt 13 will first retreat when it touches the second stop block 10, and then the bolt 13 will be inserted into the bolt hole 14 under the reset action of the spring 21 after being aligned with the bolt hole 14, and the automatic locking is completed, and when unlocking is needed, the bolt 13 can be separated from the bolt hole 14 by holding the top cap 19 and pulling it outwards, achieving the purpose of unlocking, and the overall operation is very simple in structure and steps, which is beneficial to the user to quickly operate.

[0030] Further, in order to facilitate the rollback of the bolt 13 when the bolt 13 is automatically locked during the screwing of the locking block, the top end of the bolt 13 is spherical, and the outer side of the second stop block 10 is provided as a circular arc surface. In this way, when the bolt 13 touches the second stop block 10, the bolt 13 can be more smoothly forced to roll back, and the phenomenon of jamming is not easy to occur.
