Technical Field

[0001] The utility model relates to the field of driving structures of camera waterproof shells, in particular to a knob driving structure applied to a custom button of a camera waterproof shell. Background Art

[0002] At present, underwater photography is a photography method that photography enthusiasts are keen on. The premise of realizing underwater photography with a camera is that the camera needs to be waterproof. There are many camera waterproof shells on the market, such as the camera waterproof shell information disclosed in the previous documents such as CN213124225U. However, the existing camera waterproof shells still have shortcomings. Specifically, since there are many function buttons on the camera, the camera waterproof shell also needs to be provided with corresponding buttons to trigger the function buttons in linkage. Therefore, there will be many transmission mechanisms in the camera waterproof shell; however, the transmission mechanism inside the existing camera waterproof shell is not reasonably arranged, resulting in further reduction of the internal space of the camera waterproof shell, making it difficult to arrange the positions of many transmission mechanisms, and also increasing the assembly cost; secondly, some existing combined transmission mechanisms are not designed cleverly enough, resulting in poor working stability.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] See attached Figures 1 to 8 In the embodiment of the utility model, a knob driving structure for a custom button of a camera waterproof shell includes a knob 10 that can rotate forward and reverse, the knob 10 is linked to a transmission shaft 20, a first toggle block 21 is installed on the transmission shaft 20, and the first toggle block 21 has a first toggle portion 211; the transmission shaft 20 is transmission-connected to a driving bar 30, the driving bar 30 is vertically arranged, and the driving bar 30 has a first driving hole 301 adapted to the first toggle portion 211;

[0037] The first button pin 40 and the second button pin 41 are arranged in the up-down direction.

The driving bar 30 has a first roller 31 adapted to the first push slope 401, and the driving bar 30 has a second roller 32 adapted to the second push slope 411.

[0038] When the knob 10 is rotated forward, the transmission shaft 20 drives the drive bar 30 to move upward, the first roller 31 contacts the first push slope 401, and pushes the first button needle 40 to move forward; when the knob 10 is rotated reversely, the transmission shaft 20 drives the drive bar 30 to move downward, the second roller 32 contacts the second push slope 411, and pushes the second button needle 41 to move forward.

The first rotating shaft 11 may be a square shaft, and the first gear 12 has an axial hole adapted to the square shaft.

[0042] Typically, the first toggle portion 211 is a toggle post adapted to the first drive hole 301; similarly, the second toggle portion 221 is a toggle post adapted to the second drive hole 131. The first gear 12 and the second gear 13 are typically incomplete gears. Both the first drive hole 211 and the second drive hole 131 have openings for the corresponding toggle posts to enter and assemble. Preferably, the first rotating shaft 11 is provided with a return torsion spring 14, so as to limit the angles at which the knob 10 can rotate in the positive and negative directions.

[0043] In practical application, a fixing column 50 is also included. The fixing column 50 is provided with a first through hole 51 adapted to the first button needle 40.

The second button needle 41 can be movably installed in the second through hole 52. Preferably, the fixing column 50 is also provided with a guide groove 54 adapted to the driving bar 30, so as to further improve the movement stability of the driving bar 30.

[0044] Preferably, the first button pin 40 and the second button pin 41 are both provided with a return spring 53. Specifically, the first button pin 40 has a first limit block 42 at its rear side, the first push slope 401 is provided on the first limit block 42, the second button pin 41 has a second limit block 43 at its rear side, the second push slope 411 is provided on the second limit block 43;
