Description

Technical Field

[0001] This utility model relates to the field of camera technology, and more specifically to a camera suitable for shooting at sea. Background Technology

[0002] Navigational aid operators frequently need to photograph navigational aids at sea or on shore to record their condition, location, and any potential damage. However, in practice, the design of existing camera shoulder straps presents many inconveniences, especially in marine or complex terrain environments (such as islands and reefs).

[0003] Because the existing camera shoulder straps are too long, it is difficult for navigation beacon managers to secure the camera when they move around, and they are easily tripped by the shoulder straps. Whether on a ship or walking on islands and reefs, the camera will swing and sway freely, causing bumps and knocks, which also greatly affects work efficiency. Utility Model Content

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

[0005] A camera suitable for marine photography includes a camera body with a fixing assembly. The fixing assembly includes a bracket and two adjusting straps. One end of each adjusting strap is connected to the camera body, and the other end passes through the bracket, stacked on top of each other, and slidably connected to the bracket. A driven gear is rotatably connected inside the bracket. The adjusting straps are equipped with racks that mesh with the driven gear. The driven gear can drive the two adjusting straps to slide towards or away from each other, thereby adjusting the tightness of the fixing assembly. A drive rod for driving the driven gear to rotate is rotatably connected to the bracket. A one-way limiting component for limiting the rotation direction of the drive rod is provided between the drive rod and the bracket.

[0006] The present invention is further configured such that: a first crown gear is provided on the driven gear, and a second crown gear is provided on the drive rod that meshes with the first crown gear; the drive rod drives the driven gear to rotate through the cooperation of the second crown gear and the first crown gear.

[0007] The present invention is further configured such that: the one-way limiting component includes a ratchet coaxially disposed on the drive rod and a toothed groove disposed on the bracket, the toothed groove being disposed around the periphery of the drive rod, and the drive rod being unable to rotate in the reverse direction by the cooperation of the ratchet and the toothed groove, the drive rod being slidably connected to the bracket in a direction perpendicular to the driven gear, so that the second crown gear can be separated from the first crown gear.

[0008] The present invention is further configured such that: the drive rod is slidably connected to the bracket in a direction perpendicular to the driven gear, and a return spring is provided between the drive rod and the bracket; when the return spring is in the initial state, the second crown gear meshes with the first crown gear; when the drive rod moves away from the driven gear and separates the second crown gear from the first crown gear, the return spring is compressed.

[0009] The present invention is further configured such that: a top plate is provided above the second crown gear on the bracket, and a through hole is provided on the top plate for the drive rod to pass through; one end of the return spring abuts against the top plate and the other end abuts against the second crown gear; a limit block is provided below the second crown gear on the bracket; when the return spring is in the initial state, the bottom edge of the second crown gear is in contact with the limit block.

[0010] The present invention is further provided with an operating cover at the top of the drive rod for easy gripping.

[0011] The present invention is further configured such that: a sliding hole is provided on the adjusting belt along its length direction, the driven gear passes through the sliding hole, the rack is disposed on the inner wall of the sliding hole, and the two adjusting belts are symmetrical to each other.

[0012] The present invention is further configured such that: a hook is connected to the end of the adjustment belt, and a hanging hole is provided on the camera body, and the hook is inserted into the hanging hole, thereby realizing the connection between the adjustment belt and the camera body.

[0013] The present invention is further configured such that: the adjusting belt is made of PA material, and the hook is made of stainless steel.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. The user inserts their arm between the fixing component and the camera body. The drive rod rotates the driven gear, causing the adjustment belt to slide in opposite directions, thus securing the bracket against the user's arm and fixing the camera body in place. A one-way limiting component prevents the adjustment belt from being stretched open. This invention prevents the camera from swinging or being bumped, making it convenient and practical.

[0016] 2. When the second crown gear meshes with the first crown gear, the drive rod drives the driven gear to rotate, and under the action of the ratchet, the drive rod can only rotate in the tightening direction, so that the adjusting belt will not loosen during movement; when it is necessary to loosen the fixing component, pull the drive rod outward to separate the second crown gear from the first crown gear. At this time, the driven gear can support reverse rotation, so that the fixing component is loosened.

[0017] 3. The fixing components are connected to the camera body via hooks and can be freely disassembled and installed. The fixing straps are made of PA material, while the hooks are made of stainless steel, which has good corrosion resistance and is convenient for offshore operations. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] A camera suitable for shooting at sea, such as Figures 1 to 3 As shown, the device includes a camera body 1, on which a fixing component is provided. The fixing component includes a bracket 2 and two adjusting straps 3. One end of each adjusting strap 3 is connected to the camera body 1, and the other end passes through the bracket 2, stacks on top of each other, and is slidably connected to the bracket 2. A driven gear 4 is rotatably connected inside the bracket 2. A rack 5 that meshes with the driven gear 4 is provided on the adjusting strap 3. When the driven gear 4 rotates, it can drive the two adjusting straps 3 to slide towards or away from each other, thereby adjusting the tightness of the fixing component.

[0029] A drive rod 6 for driving the driven gear 4 to rotate is rotatably connected to the bracket 2. A one-way limiting component 9 for limiting the rotation direction of the drive rod 6 is provided between the drive rod 6 and the bracket 2. The user inserts his arm between the fixing component and the camera body 1, and by rotating the drive rod 6, the bracket 2 is pressed against the user's arm, thereby fixing the camera body 1. The one-way limiting component 9 prevents the drive rod 6 from reversing, thus preventing the adjustment belt 3 from being stretched open.

[0030] The driven gear 4 is provided with a first crown gear 7, which is integrally formed with the driven gear 4 and is coaxially arranged. The bottom end of the drive rod 6 is fixed with a second crown gear 8 that meshes with the first crown gear 7. The drive rod 6 drives the driven gear 4 to rotate through the cooperation of the second crown gear 8 and the first crown gear 7. Therefore, when the drive rod 6 cannot reverse, the driven gear 4 cannot reverse because the first crown gear 7 and the second crown gear 8 are meshed, and the adjusting belt 3 cannot be loosened.

[0031] like Figures 4 to 6 As shown, the one-way limiting component 9 includes a ratchet 901 coaxially mounted on the drive rod 6 and a toothed groove 902 mounted on the bracket 2. The toothed groove 902 surrounds the drive rod 6. The drive rod 6 is a square column, and the ratchet 901 is sleeved on the square column. Therefore, the drive rod 6 will rotate synchronously with the ratchet 901. The cooperation between the ratchet 901 and the toothed groove 902 prevents the drive rod 6 from rotating in the opposite direction. When the drive rod 6 rotates in the forward direction, the two adjusting belts 3 slide towards each other. The drive rod 6 slides on the bracket 2 in a direction perpendicular to the driven gear 4, so that the second crown gear 8 can separate from the first crown gear 7. After separation, the driven gear 4 can reverse, causing the two adjusting belts 3 to slide in opposite directions.

[0032] A return spring 10 is provided between the drive rod 6 and the bracket 2. When the return spring 10 is in the initial state, the second crown gear 8 meshes with the first crown gear 7. When the user uses external force to move the drive rod 6 away from the driven gear 4 to separate the second crown gear 8 from the first crown gear 7, the return spring 10 is compressed. After the user releases his hand, the return spring 10 rebounds, and the second crown gear 8 re-meshes with the first crown gear 7.

[0033] The cross-section of the tooth block of the crown gear is a right triangle. When the tooth blocks of the first crown gear 7 and the second crown gear 8 abut, the tooth blocks are in planar contact. When the first crown gear 7 rotates, it cannot push the second crown gear 8 upward. Separation can only be achieved by the user manually pulling the drive rod 6 outward.

[0034] A top plate 11 is provided on the bracket 2 above the second crown gear 8. The top plate 11 has a through hole for the drive rod 6 to pass through. The return spring 10 is located between the top plate 11 and the second crown gear 8 and is sleeved on the periphery of the drive rod 6. One end of the return spring 10 abuts against the top plate 11 and the other end abuts against the second crown gear 8, thereby providing a downward thrust for the drive rod 6 to return to its original position. A limit block 12 is provided on the bracket 2 below the second crown gear 8. When the return spring 10 is in the initial state, the bottom edge of the second crown gear 8 is in contact with the limit block 12. At this time, the second crown gear 8 is engaged with the first crown gear 7. Since the second crown gear 8 is located between the top plate 11 and the limit block 12, the drive rod 6 will not fall off the bracket 2 when it is pulled outward.

[0035] The top of the drive rod 6 is provided with an operation cover 13 for easy gripping. The operation cover 13 is integrally formed with the drive rod 6. The operation cover 13 makes it easier for users to perform the turning operation and also makes it easier to pull the drive rod 6 outward.

[0036] like Figure 1 and Figure 2 As shown, the bracket 2 includes an upper cover 201 and a lower cover 202. The upper cover 201 and the lower cover 202 extend along the length of the adjustment belt 3. When the fixing component is tightened, the lower cover 202 will be tightly attached to the user's arm to achieve fixation. Therefore, the surface of the lower cover 202 is frosted to increase friction.

[0037] There is a channel between the upper cover 201 and the lower cover 202. The adjusting belt 3 slides in the channel. The adjusting belt 3 enters from one end of the channel and exits from the other end. A sliding hole 14 is provided on the adjusting belt 3 along its length direction. The driven gear 4 enters the sliding hole 14. The rack 5 is set on the inner wall of the sliding hole 14. The two adjusting belts 3 are symmetrical to each other. The racks 5 of the two adjusting belts 3 are located on both sides of the driven gear 4.

[0038] The end of the adjustment belt 3 is connected to a hook 15. The left and right ends of the camera body 1 are respectively provided with hanging holes 16. The hooks 15 of the two adjustment belts 3 are respectively inserted into the hanging holes 16, thereby realizing the connection between the adjustment belt 3 and the camera body 1. The user can use the hooks 15 to fix the components and the camera body 1 at any time. The adjustment belt 3 is also provided with hanging holes 16. The connection method between the hooks 15 and the adjustment belt 3 is the same as that of the camera body 1.

[0039] To prevent corrosion in the marine environment and facilitate offshore operations, hook 15 is made of stainless steel to prevent corrosion and detachment after prolonged use in the marine environment. Adjustment belt 3 is made of PA material, which has a certain degree of elasticity, high strength, wear resistance and corrosion resistance.

[0040] The working process of this utility model is as follows:

[0041] When the camera needs to be fixed, insert your arm between the camera body 1 and the fixing component, rotate the drive rod 6 to tighten the adjustment band 3, so that the camera body 1 and the bracket 2 are clamped on your arm, thereby fixing the camera. The inside of the user's arm is against the bottom of the camera body 1, and the palm can hold the camera body 1. When the camera needs to be released, pull the drive rod 6 outward to separate the second crown gear 8 from the first crown gear 7, and then simply open the adjustment band 3 outward.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
