[0019] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0020] Embodiment:
[0021] A film and television track, as Figures 1 to 4 shown, includes two track rods 1 and several connecting rods. The two ends of the connecting rods are respectively arranged on the side walls of the two track rods 1 close to each other. The connecting rod includes a sleeve 2 and a sliding rod 3. The sliding rod 3 is slidably connected to the inside of the sleeve 2 in the horizontal direction. The ends of the sleeve 2 and the sliding rod 3 facing away from each other are respectively arranged on the two track rods 1. A fastening assembly for restricting the relative position of the sliding rod 3 and the sleeve 2 is arranged on the outer wall of the sleeve 2. The number of the fastening assemblies is less than the number of the sleeves 2. The fastening assembly includes a clamp 4, a cam handle 5, a metal rod 6 and a nut 7. The inner wall of the clamp 4 is installed on the outer peripheral wall of the sleeve 2 by screws. Two symmetrically arranged short grooves 13 are opened on the outer wall of the top of the sleeve 2. The metal rod 6 passes through the inside of the clamp 4 and is rotatably connected to the cam handle 5. The nut 7 is threadedly connected to the outer peripheral wall of the metal rod 6. An external thread is arranged on the outer peripheral wall of one end of the metal rod 6, and an internal thread matching the external thread is arranged in the nut 7. The nut 7 abuts against the clamp 4.
[0022] As Figures 1 to 4 shown, when the film and television track is in normal use, the bottom surfaces of the two track rods 1 are both in contact with the ground, and the sliding rod 3, the sleeve 2 and the fastening assembly are not in contact with the ground. When it is necessary to adjust the distance between the two track rods 1 for placing film and television track cars of different widths, by simultaneously sliding several sliding rods 3, the several sliding rods 3 slide in the sleeves 2 corresponding to them respectively. When the several sliding rods 3 slide, they will drive one of the track rods 1 connected to them to move horizontally, so that the distance between the two track rods 1 will change. When the distance between the two track rods 1 is adjusted to the required state, by rotating the nut 7 to rotate it at the end of the metal rod 6 with an external thread until the nut 7 abuts against the clamp 4, and then by rotating the cam handle 5 to rotate it in the direction close to the clamp 4 until the cam handle 5 abuts against the clamp 4. During the rotation of the cam handle 5, it will push the clamp 4, so that the clamp 4 gradually squeezes the sleeve 2. At the same time, due to the existence of the two short grooves 13, the end of the sleeve 2 close to the sliding rod 3 is gradually squeezed and deformed, and the inner wall of the sleeve 2 gradually abuts against the outer wall of the sliding rod 3, and the sliding rod 3 is clamped and locked in the sleeve 2 through friction, which can provide a clamping force for the sliding rod 3, improve the stability after the telescopic adjustment of the sliding rod 3 and the sleeve 2 and is convenient for operation. At the same time, the adjustment of multiple distances between the two track rods 1 can be realized. Then, the wheels of the film and television track car can be respectively in contact with the top surfaces of the two track rods 1. By sliding the sliding rod 3 to drive one of the track rods 1 connected to it, when the distance between the two track rods 1 becomes larger, it can be used to place a film and television track car with a larger width. The user can select a corresponding film and television track car for use according to the adjustment of the distance between the two track rods 1. Thus, the distance between the two track rods 1 can be adjusted by sliding several sliding rods 3, and then it can be used to adapt to some film and television track cars of different widths. The number of the fastening assemblies being less than the number of the sleeves 2 can save the use cost of the fastening assemblies.
[0023] As shown Figures 1 to 4 in the figure, connecting plates 8 are welded to the end faces of several sleeves 2 and sliding rods 3 facing away from each other. The bottom surfaces of the connecting plates 8 and the track rod 1 are on the same horizontal plane. The connecting plates 8 are detachably connected to the track rod 1. A number of threaded holes are provided on the side wall of the track rod 1, and a number of through holes 9 are provided on the connecting plates 8. A bolt 10 is jointly arranged in the threaded hole and the through hole 9. One end of the bolt 10 passes through the through hole 9 and is threadedly connected to the threaded hole. When the film and television track is in normal use, at this time, one end of the bolt 10 is accommodated in the through hole 9 and is threadedly connected to the threaded hole, and the film and television track vehicle moves and shoots on the top surfaces of the two track rods 1, and the wheels of the film and television track vehicle do not contact the top surface of the connecting plate 8. When the top surface of the track rod 1 is sunken or damaged, it will affect the movement of the film and television track vehicle. Therefore, the damaged track rod 1 needs to be disassembled. When the track rod 1 close to the sleeve 2 is damaged and needs to be disassembled and replaced, at this time, first disassemble the bolt 10 close to the sleeve 2 so that it is separated from the threaded hole and the through hole 9 close to the sleeve 2 respectively, and then the track rod 1 close to the sleeve 2 can be disassembled from the connecting plate 8 for replacement. When the track rod 1 close to the sliding rod 3 is damaged and needs to be disassembled and replaced, at this time, first disassemble the bolt 10 close to the sliding rod 3 so that it is separated from the threaded hole and the through hole 9 close to the sliding rod 3 respectively, and then the track rod 1 close to the sliding rod 3 can be disassembled from the connecting plate 8 for replacement. When both track rods 1 are disassembled, at this time, the two connecting plates 8 and several connecting rods are disassembled as a whole at the same time, which can save the time for disassembling the two track rods 1.
[0024] As shown Figures 1 to 4 in the figure, L-shaped blocks 11 are welded to the same side wall of the two connecting plates 8, and embedding grooves 12 for the L-shaped blocks 11 to be embedded are provided on the top surfaces of the other same sides of the two connecting plates 8. The inner wall cross-section of the embedding groove 12 is L-shaped. When multiple film and television tracks need to be spliced and used, at this time, the L-shaped blocks 11 on the two connecting plates 8 of one film and television track are embedded into the embedding grooves 12 on the two connecting plates 8 of other film and television tracks from top to bottom. At this time, the L-shaped blocks 11 are in mutual fit with the inner wall of the embedding groove 12, which can avoid the horizontal offset of adjacent two film and television tracks and play a role of horizontal limiting and pre-fixing for the two film and television tracks.
[0025] The track rod 1 and the connecting rod are both made of aluminum alloy material. Aluminum alloy has the characteristics of high strength and high hardness, which can increase the service strength of the track rod 1 and the connecting rod.
[0026] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
