Description

Technical Field

[0001] This utility model relates to the field of video shooting technology, specifically a gravity-balanced sliding track for video shooting. Background Technology

[0002] When creating video works, the shooting process is particularly important. It involves the comprehensive use of various shooting techniques and camera equipment. Among these tools, the slider is a very practical device that is widely used in video shooting. The slider can stably fix the camera on it, allowing the photographer to easily track the subject and achieve a shooting effect that moves synchronously with the subject. This shooting technique can not only capture smooth dynamic images, but also enhance the visual effects of the video, bringing a richer and more vivid visual experience to the audience.

[0003] A video shooting guide rail is disclosed in CN220453327U, which relates to the field of video shooting technology. The technical solution includes a base plate with a track on top. The track is connected to the base plate via an angle adjustment mechanism. A slider is slidably connected within the track. A driving component is also provided within the track to drive the slider to move along the track. A connecting plate is located on the top of the slider for connecting to an external camera. The connecting plate is connected to the slider via a steering component. The angle adjustment mechanism includes a fixed plate, a screw a, a movable block, a motor a, a guide plate, two support plates, two square plates, and two connecting rods. The fixed plate is fixedly connected to the center of the bottom of the track. The beneficial effect of this video shooting guide rail is that, by setting an angle adjustment mechanism, the fixed plate and track can be rotated along the support shaft under the drive of the motor a until a suitable angle is reached, facilitating shooting at an upward or oblique angle, effectively improving versatility and meeting shooting needs.

[0004] Currently, track-based equipment used for video shooting involves mounting sliding components on a slide rail for sliding and translation. The main force is on the slide rail. As the sliding distance increases, the weight on one end of the slide rail gradually shifts to the other, disrupting the rail's gravitational balance. This can lead to instability during video shooting, making the slide rail prone to tipping over. Furthermore, the imbalance, combined with the ground-fixed structure supporting the slide rail, causes the pressure to shift towards the moving end, pulling on the rail and potentially deforming its starting end.

[0005] Therefore, those skilled in the art have provided a gravity-balanced sliding track for video shooting to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a gravity-balanced sliding track for video shooting, in order to solve the problem of gravity imbalance that is prone to occur in existing sliding tracks for video shooting as mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A gravity-balanced sliding track for video shooting includes: a sliding track body, a groove fixedly formed inside the surface of the sliding track body, a movable base slidably mounted inside the sliding track body, drive rollers rotatably mounted on both sides of the movable base, a clamp fixedly mounted on the right side of the drive roller, an auxiliary wheel rotatably connected to the outer side of the clamp, a belt sleeved between the drive roller and the auxiliary wheel, a connecting gear rotatably mounted inside the movable base, a drive motor fixedly connected to the center line of the connecting gear, the connecting gear being fixedly connected to the drive roller via a coupling rod, a stabilizing platform mounted above the movable base, a bracket mounted on the upper surface of the stabilizing platform, and a shooting platform mounted on the top of the bracket.

[0009] As a further embodiment of this utility model: the connecting gear is fixedly connected to the driving roller through a coupling rod, and the coupling rod between the connecting gear and the driving roller passes through the slide groove to form a sliding structure.

[0010] As a further improvement of this utility model: the movable base forms a sliding structure between the clamp and the slide groove, and a screw is inserted above the clamp.

[0011] As a further improvement of this utility model: a ground stabilizing seat is installed at the bottom of the slide rail body by screws, and a gravity foot is fixedly installed at the bottom of the ground stabilizing seat. Screws for ground fixation are inserted at an angle on the surface of the gravity foot.

[0012] As a further embodiment of this utility model: the external structure of the ground stabilizing seat is triangular, and the ground stabilizing seats are symmetrical about the center line of the slide rail body.

[0013] As a further improvement of this utility model: the symmetrical points of the ground stabilizing seats coincide and intersect each other, and the two sets of ground stabilizing seats are fixedly connected.

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

[0015] A groove is provided inside the middle of the slide rail body. The two sides of the movable base form a sliding structure with the slide rail body through clamps. Drive rollers and auxiliary wheels are installed on both sides of the movable base. The drive rollers are rotated by a drive motor. The drive rollers and auxiliary wheels pass through the groove and contact the ground outside the slide rail body. In this way, the point of force of the movable base is on the ground, not entirely on the slide rail. The slide rail body and the groove guide the movement direction of the movable base. As the movable base moves forward along the slide rail, it gradually moves away from the starting end of the slide rail body. Because of the setting of drive rollers and auxiliary wheels, and the groove being opened in the middle of the slide rail body, it is easy for drive rollers and auxiliary wheels to pass through. This changes the original point of force on the slide rail body and moves the movable base away from the starting end of the slide rail body. Since the point of force is concentrated on the ground, there will be no situation of gravity imbalance on the ground as the movable base moves. Therefore, even if the movable base moves continuously and moves far away from the starting end, it will not cause gravity imbalance of the slide rail body. 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a gravity-balanced sliding track for video shooting, comprising: a sliding track body 1, a sliding groove 2 fixedly opened inside the surface of the sliding track body 1, a movable base 3 slidably installed inside the sliding track body 1, a ground stabilizing seat 4 installed at the bottom of the sliding track body 1 by screws, and a gravity foot 16 fixedly installed at the bottom of the ground stabilizing seat 4, with screws 15 for ground fixation inserted obliquely through the surface of the gravity foot 16, the external structure of the ground stabilizing seat 4 being triangular, and the ground stabilizing seats 4 being symmetrical about the center line of the sliding track body 1, the symmetrical points of the ground stabilizing seats 4 coinciding and intersecting each other, and the two sets of ground stabilizing seats 4 being fixedly connected;

[0023] Specifically, a triangular ground stabilizing seat 4 is installed at the bottom of the slide rail body 1. Two sets of triangular ground stabilizing seats 4 are symmetrically arranged, and the symmetrical points of the two sets are staggered and fixed. In this way, the stability of the bottom of the slide rail body 1 is increased by using the stabilizing structure of the triangle. When the moving base 3 moves along the slide rail body 1 to the middle of the slide rail body 1, the center of gravity is stabilized at the overlapping position in the middle due to the two sets of symmetrical ground stabilizing seats 4. As the moving base 3 moves continuously, the moving base 3 gradually moves from above the right set of ground stabilizing seats 4 to above the left set of ground stabilizing seats 4. The overlapping part in the middle is a stable transition point. In this way, the two sets of ground stabilizing seats 4 cooperate with each other, which greatly improves the stability of the bottom of the slide rail body 1.

[0024] Drive rollers 8 are rotatably mounted on both the left and right sides of the movable base 3. A clamp 11 is fixedly mounted on the right side of the drive roller 8. An auxiliary wheel 9 is rotatably connected to the outside of the clamp 11. A belt 10 is sleeved between the drive roller 8 and the auxiliary wheel 9. A connecting gear 14 is rotatably mounted inside the movable base 3. A drive motor 13 is fixedly connected to the center line of the connecting gear 14. The connecting gear 14 is fixedly connected to the drive roller 8 through a coupling rod. A stabilizing platform 5 is mounted on the top of the movable base 3. A bracket 6 is mounted on the upper surface of the stabilizing platform 5. A shooting platform 7 is mounted on the top of the bracket 6. The connecting gear 14 is fixedly connected to the drive roller 8 through a coupling rod. The coupling rod between the connecting gear 14 and the drive roller 8 passes through a slide groove 2 to form a sliding structure. The movable base 3 forms a sliding structure between the clamp 11 and the slide groove 2. A screw 12 is inserted above the clamp 11.

[0025] Specifically, the drive motor 13 drives the connecting gear 14 to rotate. The connecting gear 14 forms a rotating structure inside the movable base 3, which facilitates the rotation of the connecting gear 14 under the drive of the drive motor 13. At the same time, the connecting gear 14 is fixedly connected to the drive roller 8 through a set of coupling rods. In this way, when the drive motor 13 drives the connecting gear 14 to rotate, the drive roller 8 will rotate with the connecting gear 14. The drive roller 8 passes through the slide groove 2 and is located on the outside of the slide rail body 1, and is in contact with the ground. In this way, the point of force is transferred from the slide rail body 1 to the ground, reducing the number of points of force on the slide rail body 1. When rolling, the belt 10 drives the auxiliary wheel 9 to roll in conjunction with the drive roller 8, thereby driving the movable base 3 along the slide rail. The main body 1 moves. In addition, the drive roller 8 is connected to the connecting gear 14 and drive motor 13 inside the moving base 3 through a set of coupling rods, and forms a rotatable connection. A clamp 11 is set between the auxiliary wheel 9 and the moving base 3. The clamp 11 is slidably installed in the slide groove 2, and the upper part of the clamp 11 is connected and sealed by the screw 12, so that the clamp 11 is slidably installed on the slide groove 2. The auxiliary wheel 9 is rotatably installed on the clamp 11 and moves on the drive of the belt 10. The clamp 11 improves the connection stability between the moving base 3 and the slide groove 2. When the moving base 3 moves along the slide rail main body 1, it will drive the stabilizing platform 5 above the moving base 3 to move. The shooting platform 7 is installed on the stabilizing platform 5 through the bracket 6, thereby completing the video shooting.

[0026] The working principle of this utility model is as follows:

[0027] When using this utility model, first start the drive motor 13. The drive motor 13 drives the connecting gear 14 to rotate. The connecting gear 14 drives the coupling rod and the drive roller 8 to rotate. The drive roller 8 rolls on the ground and drives the auxiliary wheel 9 to roll synchronously through the belt 10. The auxiliary wheel 9 slides along the slide groove 2 through the clamp 11, thereby driving the movable base 3 to move smoothly along the slide rail body 1. The movement of the movable base 3 drives the upper stabilizing platform 5 and the shooting platform 7 on the bracket 6 to move synchronously, realizing a smooth translation effect for video shooting. At the same time, the ground stabilizing seat 4 at the bottom of the slide rail body 1 is fixed to the ground by the gravity feet 16 and screws 15. The triangular structure of the ground stabilizing seat 4 increases the stability of the slide rail body 1. Especially when the movable base 3 moves to the middle position of the slide rail body 1, the overlapping part of the two sets of ground stabilizing seats 4 provides stable transition support, ensuring the stability and balance of the entire slide rail translation track during the video shooting process.

[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.
