Description

Technical Field

[0001] This utility model relates to the field of camera track technology, specifically to a sliding track for a camera device. Background Technology

[0002] In film and television production, advertising shooting, event recording, and social media creation, in order to obtain smooth and stable video effects, it is often necessary to use a sliding rail to assist the shooting device (such as camera, video camera, mobile phone gimbal, etc.) in translational movement. The core function of the sliding rail is to provide a precise and stable path for the shooting device.

[0003] Currently, the most common camera slide rails on the market are mainly divided into two categories: manual slide rails and electric slide rails. The first is the manual slide rail, where the operator directly pushes the slider carrying the camera device to move on the track. This method is simple in structure and low in cost, but its biggest drawback is that its stability is highly dependent on the operator's skill and stability. During the pushing process, it is difficult to avoid human-induced shaking. The second is the electric slide rail, which uses a motor to drive a synchronous belt and other structures to achieve automatic movement of the slider, reducing the reliance on manual operation. However, after a long period of use, the synchronous belt is prone to aging and loosening. When the drive end rotates to a certain angle, it often cannot completely transmit the signal to the driven end (the drive end needs to tighten the synchronous belt before it can move), resulting in accuracy errors. This requires a device to solve the above problems. Utility Model Content

[0016] This utility model provides a sliding track for a shooting device. Through the cooperation of a support plate, a guide rod, and a guide plate, the support plate supports the guide rod, allowing the guide plate to slide on the guide rod, resulting in more stable shooting and reduced shaking during shooting. Through the cooperation of a drive mechanism, guide wheels, and a synchronous belt, during shooting, the drive mechanism drives one of the guide wheels to rotate, causing the guide wheel to move the synchronous belt, which in turn carries the guide plate to slide on the guide rod, resulting in smoother shooting and reduced shaking. An adjustment mechanism located at the bottom of the first extension plate allows for adjustment of the synchronous belt tension, making the synchronous belt transmission more accurate and reducing the possibility of the drive mechanism moving without load.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 6 The present invention provides a technical solution: a sliding track for a shooting device, including a guide rod 1 and a support plate 2 fixed at both ends of the guide rod 1. A guide plate 3 is slidably connected to the surface of the guide rod 1, and an mounting plate 24 is provided on the upper surface of the guide plate 3 for mounting the shooting device.

[0026] There are two support plates 2. A first extension plate 4 and a second extension plate 5 are fixedly connected to one side of each support plate 2. Guide wheels 6 are provided on the lower surfaces of the first extension plate 4 and the second extension plate 5. A synchronous belt 7 is meshed with the outer surface of the guide wheel 6. One end of the synchronous belt 7 is fixedly connected to the lower surface of the guide plate 3 to drive the guide plate 3 to move. A drive mechanism is provided on the surface of the second extension plate 5 to drive the guide wheel 6 to rotate.

[0027] The lower surface of the first extension plate 4 is provided with an adjustment mechanism to adjust the tension of the synchronous belt 7.

[0028] Support plate 2 supports guide rod 1, and guide plate 3 can slide along guide rod 1. Support plate 24 has multiple bolt holes of different diameters and positions to accommodate different types of shooting equipment. The drive mechanism drives the bottom guide wheel 6 to rotate, and guide wheel 6 meshes with synchronous belt 7, so that when guide wheel 6 rotates, it can drive synchronous belt 7 to move. One end of synchronous belt 7 is fixed to guide plate 3, so that when synchronous belt 7 moves, it can drive guide plate 3 to slide along guide rod 1. By adjusting the adjustment mechanism, the tension of synchronous belt 7 can be adjusted to reduce the possibility of transmission deviation.

[0029] In this embodiment, as a preferred option, the driving mechanism is a drive motor 8, and the number of guide wheels 6 is four and arranged in a rectangular shape. The drive motor 8 is fixedly connected to the upper surface of the second extension plate 5, and the output end of the drive motor 8 passes through the second extension plate 5 and is fixedly connected to one of the guide wheels 6 to drive the guide wheel 6 to rotate.

[0030] The drive motor 8 drives the bottom guide wheel 6, which meshes with the external synchronous belt 7, thereby causing the guide wheel 6 to drive the synchronous belt 7 to move, which in turn causes the synchronous belt 7 to drive the guide plate 3 to move.

[0031] In this embodiment, as a preferred option, the adjustment mechanism includes a fixed plate 9, a threaded rod 10, and a connecting frame 11. The fixed plate 9 is fixedly connected to the lower surface of the first extension plate 4, the connecting frame 11 is slidably disposed on the lower surface of the first extension plate 4, the guide wheel 6 is rotatably disposed at both ends of the connecting frame 11, the threaded rod 10 is threadedly connected to the middle of the fixed plate 9, one end of the threaded rod 10 is rotatably connected to one side of the connecting frame 11, a guide groove 12 is provided on the lower surface of the first extension plate 4, and a guide block 13 is fixedly connected to the top of the connecting frame 11. The guide block 13 is slidably connected inside the guide groove 12.

[0032] When the threaded rod 10 is rotated, it pushes the connecting frame 11 to move to one side, thereby expanding the rectangular size enclosed by the four guide wheels 6, and thus tightening the externally meshing synchronous belt 7. This makes the rotation of the synchronous belt 7 more precise when the guide wheels 6 drive it, and reduces the idle angle when the drive wheel rotates. The guide groove 12 limits the movement direction of the first extension plate 4, so that the first extension plate 4 can only slide along the direction of the guide groove 12, reducing the occurrence of shaking of the first extension plate 4.

[0033] In this embodiment, as a preferred option, an L-shaped plate 14 is fixedly connected to the bottom of the guide plate 3, a compression spring 15 is fixedly connected to one side of the L-shaped plate 14, a mounting bracket 16 is fixedly connected to one end of the compression spring 15, and a tensioning wheel 17 is rotatably connected inside the mounting bracket 16. One side of the tensioning wheel 17 is in contact with the outer wall of the synchronous belt 7 to tension the synchronous belt 7.

[0034] The compression spring 15 pushes the mounting bracket 16 at one end to move towards the synchronous belt 7, so that the abutting wheel 17 on the mounting bracket 16 can push the synchronous belt 7 outward to further tighten the synchronous belt 7 and reduce the possibility of the drive wheel spinning freely.

[0035] In this embodiment, as a preferred option, an installation chamber 18 is provided on one side of the guide plate 3, and an auxiliary wheel 19 is provided inside the installation chamber 18. The auxiliary wheel 19 is in rolling connection with the outer surface of the guide rod 1.

[0036] The number of auxiliary wheels 19 is at least two, and in this embodiment there are two, which support the guide rod 1 on the upper and lower sides respectively, making the guide plate 3 slide more smoothly and reducing jamming. The number can also be four, which are respectively set on the upper, lower, left and right sides of the guide rod 1 to further improve the smoothness of sliding.

[0037] In this embodiment, as a preferred option, a support leg 20 is rotatably connected to one side of the support plate 2. A foot pad 21 is threadedly connected to the end of the support leg 20 away from the support plate 2. A fixing bolt 22 is threadedly connected to one side of the support leg 20. One end of the fixing bolt 22 is threadedly connected to the support plate 2. Both sides of the support leg 20 and the side of the support plate 2 near the support leg 20 are provided with protruding ridges 23. The protruding ridges 23 are used to increase the friction between the support leg 20 and the support plate 2.

[0038] The support leg 20 can rotate around the fixing bolt 22. When the surface is uneven, the support angle of the support leg 20 can be adjusted. After tightening the fixing bolt 22, the fixing bolt 22 can press the support leg 20 to move towards the support plate 2, so that the protrusion 23 on the support leg 20 engages with the protrusion 23 on the support plate 2, thereby preventing the support leg 20 from rotating. The foot pad 21 can be rotated out or retracted from the support leg 20, thereby adjusting the overall length of the support leg 20 and further facilitating the adjustment of the device to a horizontal position.

[0039] In this invention, the working steps of the device are as follows:

[0040] 1. When using, loosen the fixing bolt 22, adjust the support leg 20 to the appropriate position, and rotate the foot pad 21 at the bottom of the support leg 20 out. By adjusting the support leg 20 and the foot pad 21, the guide rod 1 is adjusted to a horizontal position.

[0041] 2. After adjustment, fix the camera on the mounting plate 24, start the drive motor 8 to drive the bottom guide wheel 6 to rotate, and the guide wheel 6 drives the synchronous belt 7 to move, thereby driving the camera on the mounting plate 24 to slide along the guide rod 1.

[0042] 3. After the timing belt 7 ages, rotate the threaded rod 10 on the fixed plate 9 to push the connecting frame 11 at one end outward, so that the guide wheels 6 at both ends of the connecting frame 11 tighten the timing belt 7 and improve the accuracy of transmission.

[0043] The specific embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
