Description

Technical Field

[0001] The utility model relates to the technical field of tracks, in particular to a portable film and television track. Background Art

[0002] Film and television tracks are important equipment for supporting and moving cameras in film and television production. They allow the camera to move along the track during shooting, thereby achieving a smooth moving shot effect, enhancing the dynamic sense and visual impact of the picture. There are various types of film and television tracks, including fixed sliding rails, portable film and television tracks, electric sliding rails, and professional camera track vehicles, etc. They are designed according to different usage scenarios and requirements. Portable film and television tracks are usually used in smaller shooting scenarios. They can provide basic moving shooting functions and are suitable for the production of micro films, advertising films, etc. They are usually made of aluminum alloy, which is convenient for movement. Portable film and television tracks are usually spliced together through connecting blocks for easy carrying. The design and material of portable film and television tracks are crucial for their stability and durability. However, for common portable film and television tracks on the market, when installed on an uneven surface, it will affect the stability of the track. Especially when the camera operator and the camera move, there will be bumps, which will affect the shooting picture. If the placement surface is relatively soft, after the splicing position of the portable film and television track is stressed, it is easy to be damaged or broken, affecting the splicing and fixing effect and the use.

The pulling member 104 tightens and fixes two adjacent track bodies 1 together, improving the strength of the splicing position of the track body 1. After the splicing position is pressed, it will not break or be damaged, enabling the track body 1 to be stably installed and used, improving stability. A pressing plate assembly 106 is fitted and installed at the top of the pulling member 104, a fixing block 107 is fixed at the bottom of the pressing plate assembly 106, and the side of the fixing block 107 is of an inclined structure; a support block structure 2; the support block structure 2 is located below the inside of the track body 1, and the bottom of the U-shaped support block structure 2 is welded and fixed to a bottom plate structure 204. A U-shaped insertion plate 201 is inserted into the side of the support block structure 2, enabling the bottom plate structure 204 to be installed and used together with the support block structure 2, stably supporting at the bottom of the track body 1, improving the stability of the track body 1, and avoiding jolting during photography.

[0025] In the embodiments of the present disclosure, as Figure 3 with Figure 4 shown, a uniformly arranged crossbar assembly 101 is fixed inside the track body 1. An arc-shaped groove is provided at the top of the crossbar assembly 101 to improve the strength of the track body 1. A support block structure 2 is installed at the bottom of the crossbar assembly 101. A long groove is penetrated and opened inside the crossbar assembly 101, and the insertion plate 201 is inserted into the long groove and slides freely, enabling the support block structure 2 to slide and displace freely to adjust the support position. A positioning block assembly 102 is welded and fixed to the bottom of the outer end of the side of the track body 1 for positioning and connecting with the pulling member 104; a clamping block assembly 103 is fixed above the outer end of the side of the track body 1, and the position of the clamping block assembly 103 corresponds to the position of the positioning block assembly 102 to improve the positioning and fixing effect on the pulling member 104. A clamping groove is provided at the top of the clamping block assembly 103, and a clamping block assembly 103 is inserted into the clamping groove. After the clamping block assembly 103 is fixed, it drives the pulling member 104 to be positioned and fixed, improving the splicing strength; an outer groove 105 is respectively opened on both sides of the bottom of the pulling member 104, enabling a guide rod assembly 108 to guide and displace inside it. The bottom end of the pressing plate assembly 106 is welded and fixed to the guide rod assembly 108. The guide rod assembly 108 penetrates the bottom of the pulling member 104 and is located inside the outer groove 105. A spring is sleeved outside the guide rod assembly 108, and the top of the spring contacts the top of the outer groove 105, continuously driving the guide rod assembly 108 to displace, so that the fixing block 107 is continuously forced to insert into the clamping groove for fixing.

[0026] In the embodiments of the present disclosure, as Figure 5 with Figure 6As shown, the side of the insertion plate 201 is welded and fixed to the fixing plate structure 202, so that the fixing plate structure 202 drives the insertion plate 201 to be spliced and used together. The fixing plate structure 202 is fixedly connected to the support block structure 2 by bolts, which facilitates the disassembly of the fixing plate structure 202, enabling the support block structure 2 to be freely disassembled and installed for use. A side groove 203 is provided on the side of the support block structure 2 to allow the fitting plate 208 to displace inside it; a bottom groove 205 is provided on each side of the bottom plate structure 204, and a limiting plate 206 made of elastic metal is fixed inside the bottom groove 205. A pyramidal rod is fixed to the bottom end of the limiting plate 206 for anti-slip contact and fixation with the placement surface; a pushing plate structure 207 made of elastic metal is fixed above the side of the bottom plate structure 204, and a fitting plate 208 is fixed above the two pushing plate structures 207.

After the position of the support block structure 2 is adjusted, the pushing plate structure 207 continuously pushes the fitting plate 208 to make anti-slip contact and fixation with the crossbar assembly 101.

[0027] The working principle of this embodiment: First, control the movement of multiple track bodies 1 for use, move the track bodies 1 to the positions where they are needed, then push the guide rod assembly 108 upward to compress the spring, control the pulling member 104 to be embedded inside the positioning block assembly 102 and the block assembly 103, and connect at the splicing position of the track bodies 1. Stop pulling the guide rod assembly 108, and the spring pushes the guide rod assembly 108, the pressing plate assembly 106, and the fixing block 107 to displace, so that the fixing block 107 is inserted into the card slot, enabling the track bodies 1 to be firmly spliced together for use. After the track bodies 1 are installed on the flexible ground, when the splicing position of the track bodies 1 is stressed, the pulling member 104 will not be damaged, effectively ensuring the connection strength of the track bodies 1. If the installation surface of the track bodies 1 is uneven, the support block structure 2 can be controlled to be installed, and then fixed through the fixing plate structure 202 and the insertion plate 201. Adjust the lateral movement of the support block structure 2 to adjust the use position of the bottom plate structure 204, and support the track bodies 1 at an appropriate position to improve the stability of the track bodies 1 and avoid jolts during photography.
