Description

Technical Field

[0001] This utility model relates to the field of underwater photography equipment technology, and in particular to a fixing device for a submersible camera. Background Technology

[0002] When underwater cameras are used for filming, their stability, ease of operation, and environmental adaptability directly determine image quality and operational efficiency. Existing fixed devices have several shortcomings: buoyancy balance and current resistance are deficient. The floats of existing devices are mostly fixed, making it impossible to adjust their position along the crossbar to accommodate different camera weights. This leads to an unbalanced underwater buoyancy distribution, making them prone to tilting or capsizing. Furthermore, the lack of a freely rotating, streamlined rudder structure makes it difficult to counteract the impact of water currents through rudder movement, causing irregular swaying of the equipment in the current and severely affecting the stability of the shooting angle. Grip and operation comfort is also insufficient. Traditional grips are mostly symmetrical straight-bar designs that do not consider ergonomics. In particular, the right upright lacks a curved structure to accommodate forearm placement, causing forearm pressure during prolonged gripping and leading to operator fatigue. The lack of non-slip grips on the handles makes them prone to slipping in wet underwater environments, increasing the risk of the equipment falling. Utility Model Content

[0003] To address the aforementioned defects or one of the defects in existing underwater camera mounting devices, this utility model provides a mounting device that is structurally reliable, highly adaptable, and provides stable underwater shooting. The technical solution adopted by this utility model is:

[0004] A underwater camera mounting device includes:

[0005] The U-shaped grip has a connector for connecting to a camera fixed in the middle of the upper crossbar;

[0006] The rotating rudder plate is a horizontal sheet that is rotatably connected to the middle of the lower crossbar via a rotating shaft. The axis of the rotating shaft is orthogonal to the axis of the lower crossbar.

[0007] Two cylindrical floats are respectively fitted onto the lower crossbars on both sides of the rotating shaft, and their positions can be adjusted along the length of the lower crossbars. Furthermore, handle sleeves are respectively fitted onto the upper crossbars on both sides of the joint.

[0008] Furthermore, the upright on the right side of the U-shaped grip frame bulges out towards the human body to form a bend, and the human forearm passes over the bend and grips the upper horizontal bar on the right side.

[0009] Furthermore, the connector is rotatably mounted in the middle of the upper crossbar via a connector seat, and a fastening nut is screwed onto the lower part of the connector seat. The pitch angle of the camera can be adjusted via the connector seat, and the adjusted angle can be locked by the fastening nut.

[0010] Furthermore, the rotating shaft is rotatably mounted on the middle of the lower crossbar via a rotating shaft seat. A countersunk hole is provided on the rotating shaft seat, and a set screw is screwed into the countersunk hole. The pitch angle of the rotating shaft around an axis perpendicular to the axial direction of the lower crossbar can be adjusted via the rotating shaft seat, and the adjusted angle can be locked by the set screw.

[0011] Furthermore, the rotating rudder plate is a teardrop-shaped streamlined structure made of ABS engineering plastic, with a rotation angle range of ±45° and rotation damping ≤0.5N·m.

[0012] Furthermore, the cylindrical float is made of closed-cell EVA foam, with a single volume buoyancy ≥15N, and is fixed to the lower crossbar by Velcro straps.

[0013] Furthermore, the connector seat is provided with multiple threaded holes for connecting external supplementary lights, laser locators, or diving flashlights. Furthermore, the total length of the U-shaped grip is 45-55cm, the height is 10-20cm, and the diameter is 3-4cm; the cylindrical float has a diameter of 8cm and a length of 20cm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Achieving dynamic buoyancy balance: By adjusting the two cylindrical floats onto the lower crossbar, the position of the floats can be flexibly adjusted according to the weight of the camera and underwater conditions, solving the buoyancy imbalance problem caused by the fixed floats in existing devices, effectively preventing the device from tilting or flipping, and ensuring stable shooting angles.

[0016] Enhanced resistance to current: The device adopts a horizontally plated rotating rudder plate, which is connected to the lower crossbar by a rotating shaft. The streamlined structure allows for free rotation to counteract the impact of water flow and reduce the irregular swaying of the equipment in the water flow, significantly enhancing the underwater resistance to current compared to existing devices.

[0017] Optimized structural adaptability: The integrated structural design of the spiral grip, combined with the camera connector in the middle of the crossbar, ensures the overall rigidity of the device and, through the coordinated action of float adjustment and rudder rotation, adapts to different models of cameras and complex underwater environments, solving the problem of limited adaptability of existing devices.

[0018] Enhanced operational reliability: The overall structure is simple and the connections between components are stable. Compared with the cumbersome structure of existing devices, it reduces shooting interference caused by loose components. At the same time, it provides a basic framework for subsequent ergonomic optimization and functional expansion, improving the convenience and reliability of underwater operation.

[0022] Please see Figure 1 This embodiment of a submersible camera fixing device includes:

[0023] The U-shaped grip 1 has a connector 2 fixed in the middle of the upper crossbar for connecting to the camera;

[0024] The rotating rudder plate 3 is a horizontal plate and is rotatably connected to the middle of the lower crossbar via a rotating shaft 4. The axis of the rotating shaft 4 is orthogonal to the axis of the lower crossbar.

[0025] Two cylindrical floats 5 are respectively fitted onto the lower crossbars on both sides of the rotating shaft 4, and their positions can be adjusted along the length of the lower crossbars.

[0026] The underwater camera fixing device in Example 1 achieves stable underwater fixation through the structural design and synergistic effect of its components. The principle is as follows:

[0027] Basic support and connection: The U-shaped grip serves as the overall support structure, with the joint of the upper crossbar directly connecting to the camera, forming a stable installation base and ensuring a rigid connection between the camera and the device.

[0028] Anti-flow and vibration damping adjustment: The horizontally plated rotating rudder is rotatably connected by a rotating shaft that is orthogonal to the lower crossbar. It can rotate freely (within ±45°) when impacted by water flow. The streamlined structure disperses the water flow force, counteracts the disturbance of water flow on the device, and reduces the shaking of the camera caused by water flow impact.

[0029] Dynamic buoyancy balance: The two cylindrical floats can be freely adjusted in position along the lower crossbars on both sides of the pivot. By changing the distribution of the floats on the crossbars, it can adapt to cameras of different weights and changes in underwater depth, balance the overall center of gravity of the device, avoid tilting or flipping due to buoyancy imbalance, and ensure the stability of the camera's shooting angle.

[0030] Structural Synergy and Stability: The frame structure of the spiral grip provides rigid support for the adjustment of the float and the rotation of the rudder. The three work together to form an integrated stability system of "load-resistance-balance" to achieve dynamic stability control during underwater filming.

[0031] In another preferred embodiment, handle sleeves 6 are respectively fitted onto the upper crossbars on both sides of the connector 2. The handle sleeves on the upper crossbars on both sides of the connector can enhance the friction and comfort when gripping, especially in the slippery underwater environment, effectively preventing slippage, while reducing hand fatigue during long-term gripping and improving operational stability.

[0032] In another preferred embodiment, the right upright of the U-shaped grip 1 bulges outward toward the human body to form a bend 11. After the human forearm passes over the bend 11, it grips the upper horizontal bar on the right side. The U-shaped grip's right upright has a bend that bulges outward toward the human body, allowing the human forearm to naturally pass over the bend. When gripping, the hand can rely on the arm's strength instead of solely bearing the weight of the wrist, significantly reducing wrist stress and achieving a labor-saving effect. The stable support of the arm enhances the overall operational stability of the device and disperses the force points, avoiding muscle strain caused by prolonged operation and significantly reducing fatigue.

[0033] In another preferred embodiment, connector 2 is rotatably mounted in the middle of the upper crossbar via connector seat 7. A fastening nut 8 is screwed onto the lower part of connector seat 7. The tilt angle of the camera can be adjusted via connector seat 7, and the adjusted angle is locked by the fastening nut 8. The connector, connected via a rotatable connector seat and locked with the fastening nut, allows for flexible adjustment of the camera's tilt angle, and the locked angle is securely maintained, meeting the angle requirements of different shooting scenarios. The adjustment operation is convenient and the positioning is precise.

[0034] In another preferred embodiment, the rotating shaft 4 is rotatably mounted on the middle of the lower crossbar via a rotating shaft seat 9. A countersunk hole is formed on the rotating shaft seat 9, and a set screw 10 is screwed into the countersunk hole. The pitch angle of the rotating shaft 4 around an axis perpendicular to the axial direction of the lower crossbar can be adjusted via the rotating shaft seat 9, and the adjusted angle is locked by the set screw 10. The rotating shaft is connected via a rotating shaft seat with a set screw, allowing adjustment and locking of the pitch angle of the rotating shaft around the axial direction perpendicular to the lower crossbar. This allows adjustment of the rudder's angle of attack according to the water flow direction or shooting requirements, enhancing its resistance to current. The set screw locking ensures the angle remains stable and does not loosen.

[0035] In another preferred embodiment, the rotating rudder is a teardrop-shaped streamlined structure made of ABS engineering plastic, with a rotation angle range of ±45° and rotational damping ≤0.5 N·m. The use of ABS engineering plastic to create a teardrop-shaped streamlined structure, limiting the rotation angle to ±45° and damping to ≤0.5 N·m, minimizes water flow resistance, allows for rapid response to water flow disturbances and stable repositioning, and the material is resistant to seawater corrosion, extending its service life.

[0036] In another preferred embodiment, the cylindrical float is made of closed-cell EVA foam, with a single volume buoyancy ≥15N, and is fixed to the lower crossbar by Velcro straps 12. The cylindrical float, made of closed-cell EVA foam with a single volume buoyancy ≥15N, and secured with Velcro straps, provides sufficient buoyancy to balance the weight of the equipment, while also allowing for flexible position adjustment to accommodate different cameras. The Velcro design facilitates quick underwater assembly and disassembly.

[0037] In another preferred embodiment, the connector 7 is provided with multiple threaded holes 13 for connecting external supplementary lights, laser locators, or diving flashlights. The multiple threaded holes on the connector allow for the connection of auxiliary equipment such as supplementary lights and laser locators, expanding the device's functional versatility and enabling it to adapt to complex underwater shooting scenarios such as low light and precise positioning, thus improving image quality and practicality. In another preferred embodiment, the total length of the U-shaped grip 1 is 45-55cm, the height is 10-20cm, and the diameter is 3-4cm. The cylindrical float 5 has a diameter of 8cm and a length of 20cm. The dimensions of the U-shaped grip and float (total length 45-55cm, height 10-20cm, etc.) balance portability and structural stability. The rod diameter is adapted to hand grip, and the float size matches the buoyancy, ensuring overall center of gravity balance, making it suitable for divers to carry and operate.

[0038] 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.
