Description

Technical Field

[0001] This utility model belongs to the field of underwater photography accessories, and specifically relates to an underwater flipping bracket. Background Technology

[0002] With the deepening of marine exploration and underwater scientific research, underwater photography technology has been widely applied, and high-quality underwater image recording is indispensable in fields ranging from marine biological research and underwater archaeology to diving tourism. When conducting underwater photography, different lenses are typically required depending on the subject being photographed. However, for underwater photography equipment, the use of a waterproof camera housing is necessary, and the lens is generally screwed onto the front port of the housing. Disassembly and assembly underwater is cumbersome, and the removed lens is not easy to store, resulting in inconvenient and slow lens switching. Utility Model Content

[0003] To solve the above problems, the primary objective of this utility model is to provide an underwater flip bracket, which allows for quick lens switching by pre-installing the lens on the underwater flip bracket, making lens switching more convenient.

[0004] Another objective of this invention is to provide an underwater tilting support that can reduce the probability of jamming.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This utility model provides an underwater tilting support, comprising:

[0007] The first connecting ring is used to install the camera's waterproof housing;

[0008] The second connecting ring is used to mount the lens;

[0009] A flipping structure includes a flipping base, a rotating component, and a rotating shaft. The flipping base is connected to one end of the first connecting ring, the rotating component is connected to one end of the second connecting ring, and the flipping base is rotatably connected to the rotating component via the rotating shaft.

[0010] The flip-up seat has a movable position, and the rotating component is movably mounted on the movable position. The movable position includes mutually perpendicular side walls and a bottom wall. The side wall of the movable position has a first rotating contact surface, and the bottom wall of the movable position has a mounting hole. The side wall of the rotating component has a mutually perpendicular second rotating contact surface and a limiting arc surface. The first rotating contact surface and the second rotating contact surface are arranged opposite to each other, and the mounting hole is arranged opposite to the limiting arc surface. An elastic component and a limiting component are provided in the mounting hole. One end of the elastic component abuts or connects to the bottom wall of the mounting hole, and the other end abuts or connects to the limiting component. One or more limiting holes are provided on the limiting arc surface. The end of the limiting component away from the elastic component can be movably locked into the limiting hole.

[0011] Furthermore, two limiting holes are provided, which are respectively located on opposite sides of the limiting arc surface and are both on the movement path of the limiting member. When the first connecting ring and the second connecting ring are folded together, the limiting member can be locked in one of the limiting holes. When the first connecting ring is unfolded relative to the second connecting ring, the limiting member can be locked in the other limiting hole.

[0012] In this application, when the first connecting ring is folded over the second connecting ring, the limiting hole on one side of the rotating member can be aligned with the mounting hole. The limiting member can enter the limiting hole under the compression of the elastic member, thereby achieving positioning between the rotating member and the flip base. This makes the folding between the first connecting ring and the second connecting ring more stable, thus improving the structural stability during lens use. When the first connecting ring is flipped 180 degrees and fully unfolded relative to the second connecting ring, the limiting hole on the other side of the rotating member can be aligned with the mounting hole. The limiting member can enter the limiting hole under the compression of the elastic member, thereby achieving positioning between the rotating member and the flip base. This makes the unfolding between the first connecting ring and the second connecting ring more stable, thus improving the structural stability after lens switching.

[0013] In existing flip-up brackets, the limiting component is typically mounted on the rotating contact surface. Due to structural interference between the limiting component and the rotating contact surface, jamming can easily occur during rotation. This application, through the above-described structural design, places the limiting component on a limiting arc surface perpendicular to the first and second rotating contact surfaces. This allows the limiting component to disengage from the first and second rotating contact surfaces, preventing structural interference with the relative movement of the first and second rotating contact surfaces and thus reducing the probability of jamming.

[0014] Furthermore, the limiting member includes a spherical bead, and the limiting hole is a concave spherical hole, with the spherical surface of the bead fitting into the spherical hole. Using the bead for limiting also provides a certain damping effect, improving structural stability.

[0015] Furthermore, the elastic element includes a spring.

[0016] Furthermore, the left and right side walls of the movable position are provided with first shaft holes in opposite positions, the rotating part is provided with a second shaft hole, the rotating shaft passes through the second shaft hole, and the two ends of the rotating shaft are respectively inserted into the two first shaft holes.

[0017] Furthermore, a threaded hole communicating with the outer side of the first shaft hole is provided, and a plug is installed in the threaded hole.

[0018] Furthermore, the second connecting ring has a positioning protrusion at the end away from the rotating member, and the first connecting ring has a clamping structure at the end away from the flipping seat that can clamp or release the positioning protrusion, with the positioning protrusion and the clamping structure corresponding to each other.

[0019] Furthermore, the clamping structure includes a clamping seat, a clamping handle, a torsion spring, and a clamping shaft. The clamping seat is fixed to one end of the flipping seat via the second connecting ring. The clamping handle is movably mounted on the clamping seat via the clamping shaft, and a clamping groove for limiting and positioning the protrusion is formed between the clamping handle and the first connecting ring. The torsion spring is sleeved on the clamping shaft, and one end of the torsion spring abuts against the clamping seat, while the other end abuts against the clamping handle.

[0020] The beneficial effects of this utility model are as follows: Compared with the prior art, the underwater flip bracket of this application is provided with a first connecting ring, a second connecting ring, and a flip structure. The first connecting ring can install a waterproof camera housing for underwater photography equipment, the second connecting ring can be used to install a lens, and the flip structure can realize the flip connection between the first connecting ring and the second connecting ring, thereby enabling the lens to flip relative to the waterproof camera housing, facilitating quick lens switching through flipping, and making lens switching more convenient.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To achieve the above objectives, the technical solution of this utility model is as follows:

[0031] See Figure 1-7 As shown, this embodiment provides an underwater tilting support, including:

[0032] The first connecting ring 1 is used to install the camera waterproof housing;

[0033] The second connecting ring 2 is used to mount the lens;

[0034] The flip structure 3 includes a flip base 31, a rotating component 32, and a rotating shaft 33. The flip base 31 is connected to one end of the first connecting ring 1, and the rotating component 32 is fixedly connected to the connecting post 21 at one end of the second connecting ring 2 by screws. The flip base 31 is rotatably connected to the rotating component 32 through the rotating shaft 33.

[0035] The flip-up seat 31 has a movable position 311, and the rotating member 32 is movably mounted on the movable position 311. The movable position 311 includes mutually perpendicular side walls and a bottom wall. The side wall of the movable position 311 has a first rotating contact surface 315, and the bottom wall of the movable position 311 has a mounting hole 314. The side wall of the rotating member 32 has a mutually perpendicular second rotating contact surface 323 and a limiting arc surface 324. The first rotating contact surface 315 and the second rotating contact surface 323 are arranged opposite to each other, and the mounting hole 314 is arranged opposite to the limiting arc surface 324. An elastic member and a limiting member are provided in the mounting hole 314. One end of the elastic member abuts or connects with the bottom wall of the mounting hole 314, and the other end abuts or connects with the limiting member. The limiting arc surface 324 has one or more limiting holes 322. The end of the limiting member away from the elastic member can be movably locked into the limiting hole.

[0036] Furthermore, two limiting holes 322 are provided. The two limiting holes 322 are respectively provided on opposite sides of the limiting arc surface 324, and both are on the movement path of the limiting member. When the first connecting ring 1 and the second connecting ring 2 are folded together, the limiting member can be locked in one of the limiting holes. When the first connecting ring 1 is unfolded relative to the second connecting ring 2, the limiting member can be locked in the other limiting hole.

[0037] In this application, when the first connecting ring 1 is folded over the second connecting ring 2, the limiting hole on one side of the rotating member 32 can be aligned with the mounting hole 314. The limiting member can enter the limiting hole under the compression of the elastic member, thereby achieving the positioning between the rotating member 32 and the flip base 31, making the folding between the first connecting ring 1 and the second connecting ring 2 more stable, thus improving the structural stability during lens use. When the first connecting ring 1 is flipped 180 degrees and fully unfolded relative to the second connecting ring 2, the limiting hole on the other side of the rotating member 32 can be aligned with the mounting hole 314. The limiting member can enter the limiting hole under the compression of the elastic member, thereby achieving the positioning between the rotating member 32 and the flip base 31, making the unfolding between the first connecting ring 1 and the second connecting ring 2 more stable, thus improving the structural stability after lens switching.

[0038] In existing flip-up brackets, the limiting component is usually installed on the rotating contact surface. Due to structural interference between the limiting component and the rotating contact surface, jamming is easily caused during rotation. This application, through the above-described structural design, places the limiting component on a limiting arc surface 324 perpendicular to the first rotating contact surface 315 and the second rotating contact surface 323. This allows the limiting component to disengage from the first rotating contact surface 315 and the second rotating contact surface 323, preventing structural interference between the limiting component and the relative movement of the first rotating contact surface 315 and the second rotating contact surface 323, thereby reducing the probability of jamming.

[0039] Furthermore, the limiting component adopts a spherical bead 36, and the limiting hole 322 is a concave spherical hole, with the spherical surface of the bead 36 fitting into the spherical hole. Using the bead 36 for limiting also provides a certain damping effect, improving structural stability.

[0040] Furthermore, the elastic element is a spring 35.

[0041] Furthermore, the left and right side walls of the movable position 311 are provided with first shaft holes 312 that are positioned opposite each other, the rotating part 32 is provided with a second shaft hole 321, the rotating shaft 33 passes through the second shaft hole 321, and the two ends of the rotating shaft 33 are respectively inserted into the two first shaft holes 312.

[0042] Furthermore, a threaded hole 313 communicating with the first shaft hole 312 is provided on the outer side of the first shaft hole 312, and a plug 34 is installed in the threaded hole 313. When installing the rotating shaft 33, the rotating shaft 33 is first inserted into the first shaft hole 312 and the second shaft hole 321 through the threaded hole 313, and then the plug 34 is installed in the threaded hole 313 to seal the rotating shaft 33; when disassembling the rotating shaft 33, the plug 34 in the threaded hole 313 is first removed, and then the rotating shaft 33 is removed. The above design can not only facilitate the disassembly and assembly of the rotating shaft 33, but also improve the stability of the rotating shaft 33.

[0043] Furthermore, the second connecting ring 2 has a positioning protrusion 22 at the end away from the rotating member 32, and the first connecting ring 1 has a clamping structure 4 at the end away from the flipping seat 31, which can clamp or release the positioning protrusion 22. The positioning protrusion 22 and the clamping structure 4 are positioned opposite each other. When the first connecting ring 1 is folded over the second connecting ring 2, the clamping structure 4 can clamp and fix it to the positioning protrusion 22, making the folding between the first connecting ring 1 and the second connecting ring 2 more stable; when the first connecting ring 1 needs to be unfolded relative to the second connecting ring 2, it is only necessary to release the positioning protrusion 22 by clamping structure 4.

[0044] Furthermore, the clamping structure 4 includes a clamping seat 41, a clamping handle 42, a torsion spring 43, and a clamping shaft 44. The clamping seat 41 is fixed to one end of the flipping seat 31 from the second connecting ring 2. The clamping handle 42 is movably mounted on the clamping seat 41 through the clamping shaft 44, and a clamping groove 45 for limiting and positioning the protrusion 22 is formed between the clamping handle 42 and the first connecting ring 1. The torsion spring 43 is sleeved on the clamping shaft 44, and one end of the torsion spring 43 abuts against the clamping seat 41, and the other end abuts against the clamping handle 42. In normal conditions, the clamping handle 42 is held against the clamping seat 41 by the torsion spring 43, so that the clamping groove 45 can clamp the positioning protrusion 22. When it is necessary to release or clamp the positioning protrusion 22, simply press the clamping handle 42 to move relative to the clamping seat 41, expand the clamping groove 45, and make it easier for the positioning protrusion 22 to enter into the clamping groove 45 or to disengage from the clamping groove 45.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
