Description

Technical Field

[0001] This utility model relates to the field of underwater shooting device technology, and in particular to a camera dial drive assembly with elastic clamping and elastic avoidance. Background Technology

[0002] As we all know, underwater photography equipment is mainly used to photograph underwater scenes, and the resulting scenes give a brand new artistic aesthetic. In recent years, it has become very popular among photographers. Underwater photography is basically done with the help of a camera, but it is necessary to put the camera into a waterproof shell to ensure that the camera can be used normally underwater. For waterproof housings, existing housings typically have a linkage mechanism on the outside to access camera function keys. For example, since cameras have focusing capabilities, existing waterproof housings usually have a drive component (control module) for moving the camera's focus dial. However, existing drive components for moving the camera's focus dial have some shortcomings. Specifically, for cameras like Canon and Panasonic, the focus dial is located on the top, and the existing drive component is also located on the top of the waterproof housing, which is inconvenient for users. The addition of the drive component increases the size of the housing, and underwater shooting requires both hands to hold the sides of the housing, so its top location makes operation difficult. Furthermore, existing drive components are prone to slippage between the camera and the dial due to loose mounting, resulting in ineffective operation and unresponsiveness. In addition, the camera's uneven surfaces can easily rub against the existing drive component when mounted in the waterproof housing, potentially damaging the camera. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a camera dial drive assembly with elastic pressing and elastic avoidance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A camera dial drive assembly with elastic clamping and elastic avoidance includes a mounting block fixedly installed inside a waterproof housing. A rotatable driven rod and an adjusting rod are shaft-connected to the mounting block. One end of the adjusting rod extends outside the waterproof housing and has an adjusting knob. The adjusting rod and the driven rod are linked. A rotating block is hinged to the upper end of the mounting block. A rotatable toggle lever is shaft-connected to the top of the upper half of the rotating block. A first elastic element is provided between the lower half of the rotating block and the mounting block, and can abut against the mounting block under external force. The actuating lever has a toothed part at one end, which is made of a flexible material. When the lower half of the rotating block is attached to the mounting block, the actuating lever and the driven lever are linked. The front of the lower half of the rotating block has a movable cavity. A movable block that cannot be separated from the movable cavity is placed inside the movable cavity. A second elastic element is provided between the bottom surface of the movable block and the bottom of the movable cavity. A top contact block is provided at the opening of the movable cavity, and the top of the top contact block is placed outside the movable cavity. The top contact block is made of a flexible material.

[0006] Preferably, the adjusting rod is located at the lower end of the mounting block and is arranged in the same plane or parallel to the mounting block; the driven rod is perpendicular to the adjusting rod; and the actuating rod is perpendicular to the driven rod.

[0007] Preferably, the driven rod is linked to the adjusting rod and the actuating rod through bevel gears.

[0008] Preferably, the teeth are made of plastic, and both the first and second elastic elements are springs.

[0009] Preferably, the top contact block is made of soft rubber.

[0010] Preferably, a waterproof bushing is provided between the adjusting rod and the waterproof shell, and a waterproof rubber ring is provided between the waterproof bushing and the adjusting rod or the waterproof shell.

[0011] Preferably, the rotating block has a slot in the movable cavity, a bolt is inserted into the slot, and the end of the bolt is connected to the movable block; or, the rotating block is locked with a bolt in the movable cavity, the movable block has a slot, and the end of the bolt is placed in the slot.

[0012] By adopting the above-mentioned solution, this utility model firstly moves the adjustment knob, which originally needed to be located on the upper surface of the waterproof housing, to the side of the waterproof housing by setting up the toggle lever, driven lever, and adjustment lever, thereby facilitating user operation. At the same time, relying on the rotatable design of the rotating block, after the camera is placed in, the protruding part in front of the camera elastically presses against the top contact block on the movable block, thereby causing the movable block to elastically press against the rotating block, allowing the teeth on the rotating block to automatically engage with the dial. The flexible design of the teeth, and the pressure formed by the flexibility, prevents slippage between the teeth and the dial. Furthermore, relying on the flexible top contact block and the second elastic element, the protruding part of the camera can be flexibly contacted when the camera is placed in, avoiding hard scratches and effectively protecting the camera.

[0022] like Figures 1 to 6 As shown, where Figure 4For ease of illustration, only half of the waterproof housing structure diagram is shown. This embodiment provides a camera dial drive assembly with elastic clamping and elastic avoidance, including a mounting block 1 fixedly installed inside the waterproof housing 100. A rotatable driven rod 2 and an adjusting rod 3 are shaft-connected to the mounting block 1. One end of the adjusting rod 3 extends outside the waterproof housing 100 and is equipped with an adjusting knob 4. The adjusting rod 3 and the driven rod 2 form a linkage relationship. A rotating block 5 is hinged to the upper end of the mounting block 1. A rotatable toggle rod 6 is shaft-connected to the top of the upper half of the rotating block 5. A first elastic element 20 is provided between the lower half of the rotating block 5 and the mounting block 1. Under external force, it can be attached to the mounting block 1. One end of the actuating rod 6 is provided with a tooth 7, which is made of flexible material. When the lower half of the rotating block 5 is attached to the mounting block 1, the actuating rod 6 and the driven rod 2 form a linkage relationship. The front of the lower half of the rotating block 5 is provided with a movable cavity 8. The movable block 9 that cannot be separated from the movable cavity 8 is placed inside the movable cavity 8. A second elastic element 10 is provided between the bottom surface of the movable block 9 and the bottom of the movable cavity 8. A top contact block 11 is provided at the opening of the movable block 9 in the movable cavity 8. The top of the top contact block 11 is placed outside the movable cavity 9. The top contact block 11 is made of flexible material.

[0023] In practical application, a certain space is required between the pawl 7 and the waterproof housing 100 to accommodate the movement of the rotating block 5 when it is turned open. Before the camera 101 is inserted, the first elastic element 20 installed between the mounting block 1 and the rotating block 5 will elastically rotate the rotating block and the movable block 9 outwards, causing the pawl 7 to retract. Then, the camera 101 can be aligned and inserted into the waterproof housing 100. As the camera 101 is gradually inserted, the protruding part of the camera 101 will first press against the top contact block 11, thereby applying force. The rotating block 5 is gradually moved back to its original position. Combined with the flexible design of the teeth 7, the rotating block 5 can continue to move after contacting the camera dial 102 until the teeth 7 and the camera dial 102 are pressed together. As the camera 101 continues to move, the top contact block 11 on the movable block 9 can retract within the movable cavity 8 under the action of the second elastic element 10, actively avoiding contact and forming an elastic pressure. The flexibility of the top contact block 11 itself prevents scratching of the camera 101. Once the camera 101 is installed between the camera and the waterproof housing 100, the dial drive operation can be performed. During dial drive operation, the user simply rotates the adjustment knob 4. After the adjustment rod 3 rotates, it drives the driven rod 2 to rotate. After the driven rod 2 rotates, the actuating rod 6 and the driven rod 2 form a linkage relationship, so the actuating rod 6 will also rotate synchronously. The teeth 7 at the other end of the actuating rod 6 will also rotate, thereby pushing the camera dial 102 to rotate.

[0024] Furthermore, in order to place the adjustment knob 4 on the side of the waterproof shell, the adjustment rod 3 in this embodiment is located at the lower end of the mounting block 1 and is arranged on the same plane or parallel to the mounting block 1. The driven rod 2 is arranged perpendicularly to the adjustment rod 3, and the toggle rod 6 is arranged perpendicularly to the driven rod 2. In this way, the adjustment knob 4 can be smoothly placed on the side of the waterproof shell 100 through multiple bending designs.

[0025] Furthermore, regarding the linkage relationship between the driven rod 2, the adjusting rod 3, and the actuating rod 6, it is only necessary to satisfy the transmission requirement. Specifically, the driven rod 2, the adjusting rod 3, and the actuating rod 6 can all form a linkage relationship through bevel gears 12.

[0026] Furthermore, in this embodiment, the material of the pry bar 7 can be plastic, the first elastic element 20 and the second elastic element 10 can be springs, and the material of the top contact block 11 can be soft rubber, specifically silicone.

[0027] Furthermore, since the adjusting rod 3 passes through the waterproof shell 100, it is necessary to ensure the waterproof effect and allow rotation. Therefore, in this embodiment, a waterproof bushing 13 is provided between the adjusting rod 3 and the waterproof shell 100. In order to ensure waterproofing, a waterproof rubber ring 14 is provided between the waterproof bushing 13 and the adjusting rod 3 or the waterproof shell 100.

[0028] Furthermore, in order to restrict the direction of movement of the movable block 9, the rotating block 5 in this embodiment is provided with a strip-shaped opening 15 on the movable cavity 8, and a bolt 16 is inserted into the strip-shaped opening 15, with the end of the bolt 16 connected to the movable block 9; or, the rotating block 5 is locked with a bolt 16 in the movable cavity 8, the movable block 9 is provided with a strip-shaped opening 15, and the end of the bolt 16 is placed in the strip-shaped opening 15.

[0029] Furthermore, it should be noted that the key point of this embodiment is that, by setting up the toggle lever 6, the driven lever 2, and the adjusting lever 3, the adjusting knob 4, which originally needed to be set on the upper surface of the waterproof housing 100, is set on the side of the waterproof housing 100, thereby facilitating user operation. At the same time, relying on the rotatable design of the rotating block 5 and the flexible design of the toggle tooth 7, it can avoid slippage when the camera 101 is placed in, and after the camera 101 is placed in, the toggle tooth 7 automatically fits onto the camera dial 102, and forms a top pressure by relying on flexibility and elasticity, avoiding slippage between the toggle tooth 7 and the camera dial 102. Moreover, under the action of the flexible top contact block 11 and the second elastic member 10, the protruding part of the camera 101 can be flexibly contacted when the camera 101 is placed in, avoiding hard scratches and effectively protecting the camera 101.

[0030] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
