Description

Technical Field

[0001] The utility model relates to the technical field of underwater shooting auxiliary equipment, in particular to a shutter zoom composite key structure of a waterproof shell. Background Art

[0002] As we all know, underwater photography is one of the methods of film and television stunt photography (images), that is, photography (images) in water. During the shooting process, the photographer will carry shooting equipment (mobile phones, cameras, etc.) with waterproof shells and diving equipment, and dive into the water to shoot directly. However, general shooting equipment is not waterproof, so how to ensure the underwater shooting of the shooting equipment, the waterproof shell is one of the main key points of underwater photography.

[0003] At present, in order to realize the linkage of shooting, the existing waterproof shells are provided with corresponding buttons, such as shutter buttons and zoom buttons, and the linkage of these buttons with the shooting equipment is achieved by setting a mainboard with an integrated Bluetooth chip inside the waterproof shell, and then forming a Bluetooth connection between the Bluetooth chip and the shooting equipment, so that the shutter buttons and zoom buttons on the waterproof shell can be used to achieve linkage control. However, due to the different structures and pressing methods of the existing shutter buttons and zoom buttons, the shutter button is a downward pressing structure, and the zoom button is a left and right toggle structure, so they are independently set up at different positions of the waterproof shell, which will result in a larger design space in the waterproof shell structure, and the shutter button and zoom button will also occupy a larger area, which is not conducive to the design concept of a compact waterproof shell.

[0020] The design concept of this embodiment is mainly to design the shutter button switch 4 and the zoom switch 5 as one place, and combine the structural design to integrate the downward pressing of the shutter and the left and right sliding of the zoom into one place, so that one structure integrates multiple button structures, so that the shutter button switch 4 and the zoom switch 5 can work normally while effectively reducing the occupied area on the waterproof shell 100, which can well meet the design concept of a compact waterproof shell.

[0021] During specific operation, the shutter button is composed of the pressing cover 7, the spring 15, the top contact column 8, the key pad 14 and the shutter key switch 4. When the pressing cover 7 is pressed down, the spring 15 is compressed, and the top contact column 8 moves downward in the inner cavity of the rotating column 6, and the key pad 14 will press the shutter key switch 4, thereby completing the touch control of the shutter key switch 4. After releasing the hand, it will recover under the action of the spring 15. At the same time, the zoom button is composed of the zoom lever 10, the torsion spring 11, the rotating column 6, the rotating sleeve 12 and the zoom switch 5 (touch switch). When the zoom lever 10 is pushed left or right, the torsion spring 11 will be squeezed and deformed, and the rotating column 6 will rotate accordingly, and the rotating sleeve 12 located at the lower end of the rotating column 6 will also rotate. After the rotating sleeve 12 rotates, the touch head 13 on the rotating sleeve 12 will immediately touch the corresponding zoom switch 5, thereby completing the touch control of the zoom button. After releasing the hand, it will recover under the reaction of the torsion spring 11.

[0022] Furthermore, in order to prevent debris from entering or getting stuck at the opening of the installation cavity 2, the end of the zoom lever 10 of the present embodiment is placed outside the waterproof shell 100, and the cavity opening cover of the installation cavity 2 is provided with a blocking cover 17. The blocking cover 17 is provided with avoidance holes at the pressing cover 7 and the zoom lever 10. In this way, by covering the blocking cover 17, a shielding can be formed, which is both beautiful and can prevent foreign objects from entering.

[0023] Furthermore, in order to reduce the frictional resistance of the zoom lever 10 during movement, an arc-shaped convex strip 18 is provided at the cavity opening of the mounting cavity 2 of the present embodiment and below the zoom lever 10, and the bottom end surface of the zoom lever 10 is placed on the top end of the arc-shaped convex strip 18. In this design, only the top end of the arc-shaped convex strip 18 can contact the zoom lever 10, so that the contact area can be controlled to be very small, thereby reducing the frictional resistance.

[0024] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
