Technical Field

[0001] The present invention relates to a photographic slide rail, and in particular to a photographic slide rail with a cleaning function for film and television production. Background Art

[0002] At present, film and television has become the most popular and influential media form, deeply affecting our world. During the film and television production process, a photographic slide rail is often used for shooting. The camera is installed on the photographic slide rail to shoot a moving video.

[0003] After the photographic slide rail has been used for a long time, some dust and impurities will adhere to its surface, resulting in jamming or shaking when the camera moves. Therefore, it is necessary to clean the dust and impurities on the surface of the photographic slide rail. Currently, it is generally to regularly use a vacuum cleaner to suck the dust and impurities on the surface of the photographic slide rail. During the actual shooting process, it is often necessary to shoot in different outdoor scenes. There is more dust and impurities outdoors, and sometimes there is wind. During the shooting process, dust and impurities are easily blown onto the photographic slide rail. At this time, it is necessary to stop the shooting work to clean the dust and impurities on the photographic slide rail, which will waste some time and thus delay the shooting work. Summary of the Invention

[0004] In order to overcome the disadvantage that stopping the shooting work to clean the dust and impurities on the photographic slide rail will waste some time and thus delay the shooting work, the present invention provides a photographic slide rail with a cleaning function for film and television production that does not delay the shooting work.

Detailed implementation manners

[0038] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0039] Embodiment 1: As Figures 1-12As shown in the figure, a camera slide rail with a cleaning function for film and television production includes a slide rail 1, a bracket 2, a slide table 3, a hollow slide plate 4, a first elastic member 5, a roller 6, a mounting box 7, a brush wheel 8, a transmission assembly, a dust suction mechanism, and a clamping mechanism. There are two slide rails 1, and the two slide rails 1 are arranged opposite to each other front and back. On both the left and right sides between the two slide rails 1, there are connected brackets 2. On both the left and right sides of the slide table 3, a set of hollow slide plates 4 are slidably provided. Each set has two hollow slide plates 4, and the two hollow slide plates 4 in each set are symmetrically arranged up and down. Four first elastic members 5 are connected between the two hollow slide plates 4 in each set. The first elastic member 5 is a spring. On both the front and back sides of the hollow slide plate 4, there are rotatably connected rollers 6. The rollers 6 slidably penetrate through the slide table 3. The rollers 6 are located within the slide rail 1, and the rollers 6 can roll along the slide rail 1. On both the front and back sides of the slide table 3, four mounting boxes 7 are connected. Inside each mounting box 7, there is rotatably connected a brush wheel 8. The brush wheel 8 is rotatably connected to the slide table 3. The brush wheel 8 contacts the inner wall of the slide rail 1. The rollers 6 drive the brush wheels 8 to rotate through the transmission assembly. The dust suction mechanism is used to extract dust and impurities within the slide rail 1, and the clamping mechanism is used to clamp the hollow slide plates 4.

[0040] As Figure 2 shown, the transmission assembly consists of a large transmission wheel, a small transmission wheel, and a transmission belt. Large transmission wheels are connected to the rollers 6, and small transmission wheels are connected to the brush wheels 8. The diameter of the large transmission wheel is 4 times larger than the diameter of the small transmission wheel. A transmission belt is wound around the large transmission wheel and the small transmission wheel.

[0041] As Figures 4-7 shown, the dust suction mechanism includes a dust suction pump 91, an air pipe 92, a dust suction hood 93, a dust suction pipe 94, and a collection assembly. The dust suction pump 91 is connected to the right side of the slide table 3. The dust suction end of the dust suction pump 91 is connected to an air pipe 92. The air pipe 92 is connected to the slide table 3. The air pipe 92 is U-shaped and surrounds the slide table 3. Two dust suction hoods 93 are connected to both the front and back sides of the top of the air pipe 92. Two dust suction pipes 94 are connected to both the front and back sides of the bottom of the air pipe 92. The collection assembly is used to collect the dust and impurities extracted by the dust suction pump 91.

[0042] As Figures 5-7 shown, the collection assembly includes a baffle 95, a groove block 96, and a clamping block 97. A collection chamber is opened at the bottom of the slide table 3. The dust outlet end of the dust suction pump 91 communicates with the collection chamber. On both the front and back sides of the bottom of the slide table 3, there are slidably provided baffles 95. On the rear side of the bottom of the front baffle 95, there are connected two groove blocks 96. On the front side of the bottom of the rear baffle 95, there are slidably provided two clamping blocks 97. The clamping blocks 97 are located within the groove blocks 96.

[0043] As Figures 8-12As shown, the clamping mechanism includes a triangular block 101, a second elastic member 102, a clamping shaft 103, a U-shaped plate 104, a third elastic member 105, and a pushing block 106. Triangular blocks 101 are slidably provided on the front and rear sides inside the hollow slide plate 4. A second elastic member 102 is connected between the triangular block 101 and the hollow slide plate 4. The second elastic member 102 is a spring. Clamping shafts 103 are connected to the triangular blocks 101. The clamping shafts 103 slidably penetrate through the hollow slide plate 4. Eight slots adapted to the clamping shafts 103 are opened in the slide table 3. The clamping shafts 103 are located in the slots. U-shaped plates 104 are slidably provided inside the hollow slide plate 4. Two third elastic members 105 are connected between the U-shaped plate 104 and the hollow slide plate 4. The third elastic member 105 is a spring. Pushing blocks 106 are connected to the front and rear sides of the bottom of the U-shaped plate 104.

[0044] As Figure 17 shown, it further includes a dial block 14, and the dial blocks 14 are connected inside the mounting boxes 7.

[0045] As Figure 18 shown, it further includes a rubber scraping block 15, and rubber scraping blocks 15 are connected to the lower ends of the dust suction pipes 94.

[0046] The user can install the camera on the slide 3 and use it. The roller 6 can roll along the slide rail 1, so that the camera can move along the slide rail 1 to shoot moving videos. The roller 6 drives the brush wheel 8 to rotate through the large transmission wheel, the small transmission wheel and the transmission belt. The brush wheel 8 cleans the inner wall of the slide rail 1, so that the camera moves more smoothly and can automatically clean during use without delaying the shooting work. The diameter of the large transmission wheel is 4 times larger than that of the small transmission wheel, so the rotation speed of the brush wheel 8 can be accelerated to improve the cleaning effect. The user can start the dust suction pump 91, and the dust and impurities in the slide rail 1 are sucked into the air pipe 92 through the dust suction cover 93 and the dust suction pipe 94. The dust and impurities enter the collection chamber for collection. The baffle 95 blocks the dust and impurities in the collection chamber. The card shaft 103 is located in the card slot, so that the hollow slide plate 4 cannot move. When it is necessary to clean the dust and impurities in the collection chamber, the user pushes the card block 97 to move the card block 97 out of the groove block 96 and releases the baffle 95. The lock is unlocked, and the user can open the baffle 95 to clean the dust and impurities in the collection chamber. Under the action of the shifting block 14, the impurities on the brush wheel 8 can be shifted off to prevent the brush wheel 8 from being stained with too many impurities. The rubber scraper 15 can scrape the impurities in the slide rail 1 to improve the cleaning effect. When the slide 3 needs to be removed, the user pushes the U-shaped plate 104 to move the U-shaped plate 104 away from the slide 3. The elastic member 105 is compressed, and the U-shaped plate 104 drives the push block 106 to move. Block 106 pushes triangular block 101 to move triangular block 101, elastic member 102 is compressed, triangular block 101 drives card shaft 103 to move, card shaft 103 is moved out of the card slot, and hollow slide plate 4 is released. The user then presses two hollow slide plates 4 of the same group toward each other to separate roller 6 and slide rail 1. Elastic member 1 5 is compressed, and transmission belt has certain elasticity and does not affect the movement of roller 6. Then slide table 3 is removed to facilitate inspection and maintenance of slide rail 1 and slide table 3.

[0047] Embodiment 2: Based on embodiment 1, Figure 13 and Figure 14 As shown, a collecting mechanism is also included, which includes a collecting box 111 and a pull rod 112. The collecting boxes 111 are slidably provided on the left and right sides of the bottom of the slide rail 1, and the collecting boxes 111 are connected to the pull rods 112.

[0048] Part of the impurities cleaned by the brush wheel 8 will fall into the collection box 111 for subsequent collection. Pulling the pull rod 112 can drive the collection box 111 to move, and the collection box 111 can be removed from the slide rail 1 to facilitate cleaning of the impurities in the collection box 111.

[0049] like Figure 15As shown in the figure, it further includes a fixing mechanism, which includes a connecting block 121 and a fastening screw 122. Connecting blocks 121 are connected to both the front and rear sides of the hollow slide plate 4. Threaded holes are formed in the connecting blocks 121, and the fastening screw 122 is provided in the upper threaded hole in a threaded manner.

[0050] The user presses the two hollow slide plates 4 of the same group towards each other. The connecting blocks 121 on the upper and lower sides also move towards each other. Then, the fastening screw 122 is screwed into the lower threaded hole to connect the two hollow slide plates 4 of the same group, without having to keep pressing the hollow slide plate 4, making it more convenient to use.

[0051] As Figure 16 shown in the figure, it further includes a foot pad mechanism, which includes a connecting rod 131 and a cushion block 132. Connecting rods 131 are connected to the lower ends of the fastening screws 122, and cushion blocks 132 are connected to the lower ends of the connecting rods 131. The cushion blocks 132 are located in the lower threaded holes.

[0052] When the fastening screw 122 is screwed into the lower threaded hole, the fastening screw 122 will drive the connecting rod 131 and the cushion block 132 to move downward. The cushion block 132 can lift the slide table 3, so that the brush wheel 8 will not contact the ground, avoiding extrusion between the brush wheel 8 and the ground, and thus being able to avoid damage to the brush wheel 8.
