Description

Technical Field

[0001] This utility model relates to the field of helmet bracket technology, and in particular to a helmet bracket with multi-angle adjustment. Background Technology

[0002] Helmets, as an important type of head protection equipment, are widely used in military, cycling, skiing, firefighting, and other fields. With the development of technology and the diversification of people's needs, helmets are no longer just simple protective gear, but have gradually become multifunctional integrated platforms. People often need to install various devices such as night vision devices, cameras, and headlamps on helmets to meet the needs of different scenarios.

[0003] Currently, existing helmet brackets require two hands to adjust the tilt angle: one hand to hold the camera and the other to adjust and fix it, which is very inconvenient. Furthermore, they can only adjust the camera tilt angle, greatly limiting their applicability. Therefore, to better achieve convenient helmet bracket adjustment, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme for a helmet bracket with multi-angle adjustment, which differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenient and limited adjustment in existing helmet brackets, and to propose a multi-angle adjustable helmet bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-angle adjustable helmet bracket includes a support block and a camera. A rotating column is rotatably mounted on the top of the support block via an interlocking bearing. A worm gear is fixedly connected to the outer wall of the rotating column. A mounting plate is fixedly connected to the top of the rotating column. A mounting block is fixedly connected to the top of the support block. A worm gear is rotatably mounted between the two mounting blocks via an interlocking bearing, and the worm gear meshes with the worm gear. A fixing frame is provided on the top of the mounting plate. The camera is fixed within the fixing frame by bolts. Multiple rotating blocks are fixedly connected to the top of the mounting plate and the bottom of the fixing frame. The rotating blocks of the mounting plate and the rotating blocks of the fixing frame are rotatably connected via a rotating shaft. A connecting block is fixedly connected to one side of the fixing frame. A dovetail groove is provided on one side of the connecting block, and a slider is slidably connected within the dovetail groove. A support plate is fixedly connected to the top of the mounting plate. A second rotating rod is rotatably mounted on the support plate via an interlocking bearing. A threaded rod is fixedly connected to the top of the second rotating rod, and the threaded rod is threadedly connected to the slider.

[0007] Furthermore, one end of the support block is fixedly connected to an arc-shaped plate, and both sides of the arc-shaped plate are rotatably connected to connecting plates.

[0008] Furthermore, an adhesive layer is provided on one side of the connecting plate, and the adhesive layer is an epoxy resin adhesive layer.

[0009] Furthermore, a protective box is fixedly connected to the top of the support block, and the protective box covers the outside of the worm gear and worm.

[0010] Furthermore, one end of the worm gear extends out of the protective box and is fixedly connected to a first handle.

[0011] Furthermore, a second handle is fixedly connected to the bottom end of the second rotating rod.

[0012] Furthermore, a nut is threadedly connected to the top end of the threaded rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By turning the first handle, the worm gear is rotated, and the rotating column is rotated under the action of the worm gear and worm wheel meshing. This causes the mounting plate, the fixing bracket and the camera to rotate, thereby adjusting the direction of the camera and improving the applicability of the helmet bracket.

[0015] 2. By turning the second handle, the second rotating rod is driven to rotate, which in turn drives the threaded rod to rotate, causing the slider to move within the dovetail groove, thereby tilting the camera and adjusting its angle. This can be done with just one hand, making it convenient and quick. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A multi-angle adjustable helmet bracket includes a support block 4 and a camera 20. A rotating column 6 is rotatably mounted on the top of the support block 4 via an interlocking bearing. A worm gear 7 is keyed to the outer wall of the rotating column 6. A mounting plate 8 is welded to the top of the rotating column 6. A mounting block is integrally formed on the top of the support block 4. A worm 10 is rotatably mounted between the two mounting blocks via an interlocking bearing. The worm 10 meshes with the worm gear 7. The gap between the worm gear 7 and the worm 10 is 0.01-0.02mm. One end of the worm 20 is provided with a threaded groove. A fastening nut is threadedly connected to the threaded groove of the worm 20. Tightening the fastening nut makes it abut against the mounting block nearby, thereby fixing the worm 10. A fixing frame 13 is provided on the top of the mounting plate 8. The camera 20 is fixed in the fixing frame 13 by bolts. Under the action of the worm 10 meshing with the worm gear 7, the rotating column 6 is driven to rotate, thereby driving the mounting plate 8, the fixing frame 13 and the camera 20 to rotate, thereby adjusting the direction of the camera 20.

[0023] Multiple rotating blocks 12 are welded to the top of the mounting plate 8 and the bottom of the fixing frame 13. The rotating blocks 12 of the mounting plate 8 and the rotating blocks 12 of the fixing frame 13 are rotatably connected by rotating shafts. A connecting block 14 is fixed to one side of the fixing frame 13 by bolts. The connecting block 14 is inclined and has a dovetail groove 1401 on one side. A slider 18 is slidably connected in the dovetail groove 1401. A support plate 15 is welded to the top of the mounting plate 8. A second rotating rod 16 is rotatably mounted on the support plate 15 through an embedded bearing. A second handle 19 is welded to the bottom end, and a threaded rod 17 is welded to the top end of the second rotating rod 16. The threaded rod 17 is threadedly connected to the slider 18. Turning the second handle 19 causes the second rotating rod 16 to rotate, which in turn causes the threaded rod 17 to rotate, thereby causing the slider 18 to move. This causes the slider 18 to move within the dovetail groove 1401, thereby pushing the camera 20 to tilt and thus adjusting the angle of the camera 20. A nut is threadedly connected to the top end of the threaded rod 17. Tightening the nut fixes the threaded rod 17, thereby fixing the angle of the camera 20.

[0024] One end of the support block 4 is integrally formed with an arc-shaped plate 3. Both sides of the arc-shaped plate 3 are rotatably connected with connecting plates 1. The connecting plates 1 are elastic acrylic plates. Therefore, the connecting plates 1 can be bent into a shape that fits the arc surface of the helmet. One side of the connecting plates 1 is provided with an adhesive layer 2. The adhesive layer 2 is an epoxy resin adhesive layer. The helmet bracket is fixed to the helmet by bonding the adhesive layer 2 to the helmet.

[0025] A protective box 5 is bolted to the top of the support block 4. The protective box 5 covers the outside of the worm gear 7 and worm 10, thereby protecting the worm gear 7 and worm 10 and preventing them from being corroded.

[0026] One end of the worm gear 10 extends out of the protective box 5 and is welded with a first handle 11, which facilitates the operation of the worm gear 10.

[0027] The working principle of this embodiment is as follows: In use, firstly, the helmet bracket is fixed to the helmet by bonding the adhesive layer 2 to the helmet. Then, the first handle 11 is turned to drive the worm gear 10 to rotate. Under the action of the worm gear 10 meshing with the worm wheel 7, the rotating column 6 is driven to rotate, thereby driving the mounting plate 8, the fixing bracket 13 and the camera 20 to rotate, thereby adjusting the direction of the camera 20. Next, the second handle 19 is turned to drive the second rotating rod 16 to rotate, thereby driving the threaded rod 17 to rotate, thereby causing the slider 18 to move. This causes the slider 18 to move within the dovetail groove 1401, thereby pushing the camera 20 to tilt, thus adjusting the angle of the camera 20. Finally, the nut is tightened to fix the threaded rod 17, thereby fixing the angle of the camera 20.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
