Description

Technical Field

[0001] The utility model relates to the technical field of film and television equipment, in particular to a film and television camera slide rail. Background Art

[0002] The shooting of TV dramas and movies is mainly divided into flying shooting, mobile shooting and fixed-point shooting. Among them, mobile shooting is mainly divided into two types. The first is to install the camera pan head and camera on a vehicle, and move the pan head and camera by the vehicle. It is mainly used for shooting driving scenes. The second is to install the camera pan head and camera on a rail car, and the rail car is guided by a film and television camera slide rail and moves horizontally on the ground by human propulsion or electric drive. It is mainly used for shooting large scenes of walking, running, fighting, etc.

[0003] When using existing film and television camera slides, it is necessary to check the cables of the photographic equipment at all times to prevent the cables from being pulled and falling on the track when the track car drives the camera to move. Otherwise, the cable will easily be broken by the track car during movement, and the stability of the track car will also be affected, resulting in picture jitter. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a film and television camera slide rail to solve the technical problem that cables are easy to fall on the rail.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a film and television camera slide rail, comprising a base and a linkage seat, wherein the bottom two sides of the linkage seat are respectively connected with a slider and a roller, the linkage seat is internally connected with a push frame through a spring, the linkage seat is internally connected with a friction wheel, and the friction wheel is externally sleeved with a gear, one end of the friction wheel and the roller are both connected with a synchronous wheel, and a synchronous belt is connected between the two synchronous wheels, the top of the linkage seat is connected with a connecting plate, and the top of the connecting plate is penetrated by bolts, and the top of the base is respectively provided with a partition and a wire groove.

[0006] By adopting the above technical solution, the rail car drives the linkage seat to move while moving. When the linkage seat moves, the roller contacts the base and starts to roll. After the roller rotates, a friction wheel rotates through the synchronous wheel and the synchronous belt transmission, and then the two friction wheels rotate in opposite directions through the meshing of two gears. When the rail car moves forward, the friction wheel pulls the cable out of the cable trough through the friction wheel. When the rail car moves backward, the friction wheel sends the cable into the cable trough through friction force, thereby preventing the cable on the camera equipment from being crushed by the wheels of the rail car.

[0007] Furthermore, two partitions are provided, and the wire duct is provided between the two partitions.

[0008] By adopting the above technical solution, when the rail vehicle moves backward, the friction wheel sends the cable into the cable trough through friction, and at the same time, the partition is used to prevent the cable from contacting the slider and the roller, thereby reducing the occurrence of cable damage.

[0009] Furthermore, the slider is slidably connected to the base, and the roller is in contact with the base.

[0010] By adopting the above technical solution, the rail car drives the linkage seat to move while moving. Since the slider is located inside the base, and the slider and the rail car are both connected to the linkage seat, the derailment of the rail car can be effectively avoided. When the linkage seat moves, the roller contacts the base and starts to roll.

[0011] Furthermore, the outer ring of the friction wheel is provided with a plurality of grooves, and the cross-section of the grooves on the friction wheel is semicircular.

[0012] By adopting the above technical solution, the staff passes one end of the cable through the gap between the two friction wheels and fits the cable into the groove. When the rail car moves forward, the friction wheel pulls the cable out of the cable groove through the friction wheel. When the rail car moves backward, the friction wheel sends the cable into the cable groove through friction force.

[0013] Furthermore, two friction wheels and two gears are provided, and the two gears are meshed with each other, and the two friction wheels are respectively connected to the linkage seat and the push frame.

[0014] By adopting the above technical solution, the spring drives the push frame to reset so that the two friction wheels are close to each other and the two gears resume the meshing state. If the teeth of the two gears fit together and cannot mesh, the staff can manually rotate the friction wheel on the push frame to make the gear rotate and cooperate with the spring to push the two gears to mesh.

[0015] Furthermore, tracks are connected to both sides of the top of the base, and the two tracks are symmetrically distributed.

[0016] By adopting the above technical solution, the staff places the rail car on the track and guides the rail car through the track, so that the rail car can run smoothly.

[0017] Furthermore, push plates are connected to both sides of the linkage seat, the two push plates are both compatible with the track, and the two push plates are symmetrically distributed.

[0018] By adopting the above technical solution, the debris on the track is pushed away by the push plate, thereby reducing the impact of the debris such as stones on the track on the rail vehicle.

[0019] Furthermore, the top of the push plate is sloped.

[0020] By adopting the above technical solution, the push plate is reduced in a slope shape so that when it collides with debris, the debris can be deflected, thereby pushing the debris away from the track.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] 1. The utility model drives the linkage seat to move while the rail car moves by setting rollers, partitions, wire grooves, friction wheels and gears. When the linkage seat moves, the roller contacts the base and starts to roll. After the roller rotates, a friction wheel rotates through the synchronous wheel and the synchronous belt transmission. Then, the two friction wheels rotate in opposite directions through the meshing of two gears. When the rail car moves forward, the friction wheel pulls the cable out of the wire groove through the friction wheel. When the rail car moves backward, the friction wheel sends the cable into the wire groove through friction, thereby preventing the cable on the camera equipment from being crushed by the wheels of the rail car; effectively protecting the cable, so there is no need to focus on the cable position;

[0023] 2. The utility model uses the arrangement of a push frame and a spring to push the friction wheel on the push frame so that the two friction wheels are moved apart, thereby preventing the cable from being unable to pass through the groove between the two friction wheels due to the connector being larger than the cable. After that, one end of the cable can be passed through the groove between the two friction wheels. After releasing the hand, the spring drives the push frame to reset so that the two friction wheels are close together, and the two gears resume the meshing state. If the teeth of the two gears fit together and cannot mesh, the friction wheel on the push frame can be manually rotated to rotate the gear and cooperate with the push of the spring to make the two gears mesh, so that the cable can be passed through conveniently.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1:

[0032] A video camera slide, such as Figure 1-Figure 4 As shown, it includes a base 1 and a linkage seat 3, and a slider 6 and a roller 7 are respectively connected to the two sides of the bottom of the linkage seat 3. The slider 6 is slidably connected to the base 1. Since the slider 6 is located inside the base 1, and the slider 6 and the rail car are connected to the linkage seat 3, the derailment of the rail car can be effectively avoided; the roller 7 is in contact with the base 1, and when the linkage seat 3 moves, the roller 7 contacts with the base 1 and starts to roll; the linkage seat 3 is internally connected to two push frames 15 through two springs 16, and two friction wheels 12 are respectively connected between the inside of the linkage seat 3 and the two push frames 15. The staff pushes the friction wheel 12 on the push frame 15 with one hand to displace the push frame 15 and the friction wheel 12 on the push frame 15, so that the two friction wheels 12 are away from each other, so as to facilitate the passage of the cable; the outer rings of the two friction wheels 12 are provided with a plurality of grooves, and the cross-section of the grooves on the friction wheels 12 is semicircular. One end of the cable is passed through the gap between the two friction wheels 12 and the cable is fitted with the groove, so that the friction wheels 12 pulls out the cable in the cable groove 11 through the friction wheel 12 or sends the cable into the cable groove 11 through friction; two gears 13 are respectively sleeved on the outside of the two friction wheels 12, and the two gears 13 are meshed with each other, and the two friction wheels 12 rotate in opposite directions through the meshing of the two gears 13; one end of the friction wheel 12 and the roller 7 are connected with a synchronous wheel 8, and a synchronous belt 9 is connected between the two synchronous wheels 8. When the linkage seat 3 moves, the roller 7 contacts with the base 1 and starts to roll. After the roller 7 rotates, one friction wheel 12 rotates through the synchronous wheel 8 and the synchronous belt 9; a connecting plate 4 is connected to the top of the linkage seat 3, and a bolt 5 passes through the top of the connecting plate 4. The table of the rail car enters the connecting plate 4, and then the staff tightens the bolt 5 to connect the rail car with the linkage seat 3; two partitions 10 and a cable groove 11 are respectively arranged on the top of the base 1, and the cable groove 11 is arranged between the two partitions 10. The cables are stored and protected by the arrangement of the partition 10 and the cable groove 11 to prevent the wheels of the rail car from crushing the cables.

[0033] See also Figure 1 In the above embodiment, tracks 2 are connected to both sides of the top of the base 1, and the two tracks 2 are symmetrically distributed, which is convenient for guiding the rail vehicle so that the rail vehicle can move smoothly.

[0034] Embodiment 2:

[0035] On the basis of the above-mentioned embodiment 1, although the cables can be effectively protected by setting the roller 7, the partition 10, the wire groove 11, the friction wheel 12 and the gear 13, there is no need to focus on the cable position; but there may be some impurities on the track 2 that affect the normal operation of the rail vehicle; now by setting the push plate 14, the debris on the track 2 can be pushed away.

[0036] See also Figure 1 , Figure 3 and Figure 4 In the above embodiment, push plates 14 are connected to both sides of the linkage seat 3. The two push plates 14 are adapted to the track 2. The two push plates 14 are symmetrically distributed. The top of the push plates 14 is sloped. The push plates 14 are used to push away debris on the track 2, thereby reducing the impact of debris such as stones on the track 2 on the rail vehicle.

[0037] The implementation principle of the utility model is as follows: first, the staff places the rail car on the track 2, and the table of the rail car enters the connecting plate 4, then the staff tightens the bolts 5 to connect the rail car with the linkage seat 3, and then the staff puts the cable into the cable groove 11. At this time, the staff pushes the friction wheel 12 on the push frame 15 with one hand to displace the push frame 15 and the friction wheel 12 on the push frame 15, so that the two friction wheels 12 are away from each other, and the two gears 13 end the meshing and the spring 16 is compressed. Then the staff passes one end of the cable through the gap between the two friction wheels 12 and fits the cable with the groove. After passing the cable, the staff stops pushing the friction wheel 12. At this time, the spring 16 drives the push frame 15 to reset so that the two friction wheels 12 are close to each other, and the two gears 13 resume the meshing state. If the teeth of the two gears 13 fit each other and cannot mesh, the staff can manually rotate the friction wheel 12 on the push frame 15 to rotate the gear 13 and cooperate with the push of the spring 16 to mesh the two gears 13;

[0038] When the rail car moves, it drives the linkage seat 3 to move. Since the slider 6 is located inside the base 1, and the slider 6 and the rail car are both connected to the linkage seat 3, the derailment of the rail car can be effectively avoided. When the linkage seat 3 moves, the roller 7 contacts the base 1 and starts to roll. After the roller 7 rotates, it drives a friction wheel 12 through the synchronous wheel 8 and the synchronous belt 9, and then the two friction wheels 12 rotate in opposite directions through the engagement of two gears 13. When the rail car moves forward, the friction wheel 12 pulls out the cable in the wire groove 11 through the friction wheel 12. When the rail car moves backward, the friction wheel 12 sends the cable into the wire groove 11 through friction, thereby avoiding the cable on the camera equipment from being crushed by the wheels of the rail car. At the same time, the push plate 14 pushes away the debris on the track 2, reducing the impact of debris such as stones on the track 2 on the rail car.
