The camera track is made of high-strength stainless steel material, which is rust-proof, corrosion-resistant and bump-resistant, and is easy to transport and transfer. The quality, appearance and performance of the whole set of products have reached the level of similar foreign products, and are products that users can trust.

[0003] However, when used for some longer distance shooting, it is necessary to splice multiple shooting tracks into a long track. However, the track splicing mechanisms on the market currently mostly use threaded connection or embedded docking, and most of them are end-to-end docking methods, such as end-face threaded screw-in connection track, end-face embedded component connection track, etc. When using the end-face threaded screw-in connection track, the track end face is only processed on the two end faces, which cannot be applied to occasions where coaxial seamless connection is required for the spliced ​​track, or the connection stability is insufficient. When the embedded component connection track is used, the embedded installation is more complicated, and it is difficult to achieve a coaxial and seamless effect, and it has poor applicability for occasions requiring precise track splicing.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1:

[0023] according to Figure 1-4A track seamless splicing mechanism shown in the figure comprises a track plate 1, track rods 2 are arranged on both sides of the track plate 1, half of one side of the track rod 2 is fixedly embedded in the inner wall of the track plate 1, the track rods 2 are protruding at both ends of the track plate 1, a splicing device 3 is arranged between the two track plates 1, the splicing device 3 comprises an upper track clamping plate 4 and a lower track clamping plate 5, a plurality of countersunk screws 6 are arranged between the upper track clamping plate 4 and the lower track clamping plate 5, the front end faces and rear end faces of the upper track clamping plate 4 and the lower track clamping plate 5 are both arc-shaped, and are combined to form a semicircular arc setting, so The semicircular arc formed between the upper track clamp plate 4 and the lower track clamp plate 5 matches the half of the track rod 2 located inside the track plate 1, so that their radii are equal to achieve coaxial connection. The same basket screw 7 is arranged between the surfaces of the two track plates 1. By combining the upper track clamp plate 4 and the lower track clamp plate 5 and fixing them with the basket screw 7, a seamless connection between the two track plates 1 is achieved, which has a simple structure and convenient adjustment. In addition, the semicircular arcs of the upper track clamp plate 4 and the lower track clamp plate 5 match the track rod 2, so that the two track plates 1 are coaxially connected when connected.

[0024] Furthermore, in the above technical solution, the basket screw 7 includes a spiral adjustment sleeve 8 and two tightening screws 9, one end of the two tightening screws 9 is threadedly connected to one end of the spiral adjustment sleeve 8 respectively, and the tightening screw 9 is fixedly connected with a locking ring 10, and a locking screw 11 is movably inserted inside the locking ring 10. The locking screw 11 is located at a section of the top and bottom of the locking ring 10 and is threadedly sleeved with a limiting sleeve 12. The basket screw 7 is tightened to make the end faces of the two docking rails fully fit together to achieve a seamless connection effect.

[0025] Furthermore, in the above technical solution, the tensioning screw 9 is set in a Y shape, and one end of the tensioning screw 9 connected to the locking ring 10 is set as a double joint, and each is connected to a locking ring 10. By setting the tensioning screw 9 in a Y shape, the limiting force of the two track plates 1 is increased to prevent one of the tracks from being subjected to a larger force, causing damage to the track rod 2, thereby causing the splicing position to break.

[0026] Furthermore, in the above technical solution, both ends of the turnbuckle screw 7 are fixedly connected to the track plate 1 by means of locking screws 11 , and the locking screws 11 penetrate the track plate 1 and are sleeved with the locking ring 10 .

[0027] Furthermore, in the above technical solution, the length, width and height of the upper rail clamp 4 are equal to the length, width and height of the lower rail clamp 5, and the total height of the upper rail clamp 4 and the lower rail clamp 5 is equal to the thickness of the rail plate 1, which is conducive to forming the same structural dimensions as the rail plate 1 when the upper rail clamp 4 and the lower rail clamp 5 are combined, preventing the connection part from being uneven, thereby achieving seamless connection.

[0028] Furthermore, in the above technical solution, a section of the track rod 2 extending out of the end of the track plate 1 is 1 / 2 of the length of the upper track clamp 4 or the lower track clamp 5, and the widths of the upper track clamp 4 and the lower track clamp 5 are equal to the width of the track plate 1.

[0029] Furthermore, in the above technical solution, the length of the countersunk screw 6 is equal to the sum of the heights of the upper rail clamp 4 and the lower rail clamp 5, and the bottom end of the countersunk screw 6 extends to the internal setting of the lower surface of the lower rail clamp 5, thereby ensuring the flatness of the bottom of the overall packaging device.

[0030] Furthermore, in the above technical solution, the height of the limit sleeve 12 is greater than 1 / 2 of the height of the spiral adjustment sleeve 8 when the spiral adjustment sleeve 8 is perpendicular to the track plate 1, which is beneficial to prevent the spiral adjustment sleeve 8 from contacting the surface of the track plate 1 and the upper track clamp 4 during rotation, thereby affecting the rotation of the spiral adjustment sleeve 8.

[0031] Working principle of the present invention:

[0032] Refer to the instruction manual Figure 1-4 When the two track plates 1 are spliced, the upper track clamping plate 4 and the lower track clamping plate 5 are respectively clamped on the surface of the track rod 2 protruding between the two ends of the two track plates 1, and then the upper track clamping plate 4 and the lower track clamping plate 5 are fixed with countersunk screws 6. Since the semicircular arc formed by the front and rear sides of the upper track clamping plate 4 and the lower track clamping plate 5 matches half of the track rod 2, after the upper track clamping plate 4 and the lower track clamping plate 5 are fixed, they do not hinder sliding on the surface of the track rod 2. Then the two ends of the basket screw 7 are respectively fixed on the surfaces of the two track plates 1, and the spiral adjustment sleeve 8 is adjusted to change the length between the two ends of the basket screw 7 to reduce it, so that the two track clamping plates clamp the upper track clamping plate 4 and the lower track clamping plate 5. According to the size relationship between the upper track clamping plate 4 and the lower track clamping plate 5 and the track plate 1, the two track plates 1 are seamlessly connected, the structure is simple and the adjustment is convenient, and the semicircular arcs of the upper track clamping plate 4 and the lower track clamping plate 5 match the track rod 2, so that when connected, the two track plates 1 form a coaxial connection.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
