Description

Technical Field

[0001] The invention relates to the technical field of camera equipment, in particular to a sliding type video information acquisition device with a multifunctional self-lubricating structure. Background Art

[0002] A rail camera is typically mounted on a rail and capable of moving along it for video capture. It's primarily used for video capture. This camera system is widely used in various filming scenarios, such as film and television production, event recording, and surveillance and security. A rail camera system typically consists of a rail, camera, a mobile mechanism (such as a camera cart), and a control system.

[0003] The utility model patent with the authorization announcement number CN201620166962.9 discloses a positionable guide rail camera, which includes a guide rail, a movable box, a telescopic rod and a fast ball. The fast ball is installed at the lower end of the telescopic rod, and the upper end of the telescopic rod is installed on the movable box. The movable box can slide freely on the guide rail. A stepper motor is installed in the movable box to drive the movable box to slide along the guide rail. A claw-pole permanent magnet synchronous motor is also installed in the movable box and the telescopic rod. The claw-pole permanent magnet synchronous motor drives the telescopic rod through a transmission belt. The retractable rod is used for vertical positioning of the speed dome camera. A controller is also installed within the movable housing to control the operation of the stepper motor and claw-pole permanent magnet synchronous motor. The controller includes a counter to count the distance traveled by the claw-pole permanent magnet synchronous motor. The retractable rod consists of an upper fixed portion connected to the movable housing and a lower, retractable, telescopic portion. A trigger switch is mounted on the rod, which is connected to the counter. When the telescopic portion is fully retracted into the fixed portion, the trigger switch is triggered, generating a signal that is transmitted to the counter, resetting it to zero. This approach achieves precise positioning of the rail camera at a low cost. The solution is simple and easy to retrofit, making it worthy of widespread adoption.

[0004] While this positionable rail camera facilitates precise positioning, it still presents a practical problem: it relies on a stepper motor to drive the movable housing along a rack-type rail. Frequent operation of this design generates significant friction between the movable housing and the rail, which lacks the necessary lubrication. This constant friction not only accelerates rail wear but also compromises the camera's stable operation. Long-term performance degradation and even damage to the device are inevitable. Therefore, we propose a sliding video information acquisition device with a multifunctional self-lubricating structure. Summary of the Invention

Example

[0020] See also Figure 1-Figure 5As shown, a sliding video information acquisition device with a multifunctional self-lubricating structure includes a guide part 1, which includes a base 10.

A pump body 25 is fixed at the bottom of the cavity 201, and a drainage pipe 26 that penetrates into the transmission cavity 200 is installed at the drainage port of the pump body 25. A U-shaped elbow 27 is fixed at the end of the drainage pipe 26, and nozzles 270 for spraying lubricating liquid to the gear 22 are fixed at both ends of the bottom of the elbow 27; a liquid inlet pipe 28 is installed at the liquid inlet of the pump body 25, and the liquid inlet pipe 28 extends to the rear side of the mounting frame 20; a camera 3 for video information collection is installed on the top of the mounting frame 20.

[0021] Furthermore, a liquid supply unit 4 is installed on the rear side of the mounting frame 20. The liquid supply unit 4 includes a fixing frame 40 fixedly connected to the rear end face of the mounting frame 20. The fixing frame 40 is provided with a fixing hole 400. A tank body 41 for storing lubricating liquid is fixed to the fixing hole 400. A limiting groove 410 is provided on the outer wall of the tank body 41. A socket 411 is provided on the top of the tank body 41. The liquid inlet pipe 28 passes through the socket 411 and is inserted into the inner bottom of the tank body 41. A threaded rod 42 is threadedly connected to the center of the rear end face of the fixing frame 40. A connecting plate 44 is rotatably mounted at the front end of the threaded rod 42. A limiting block 45 is fixed to the center of the front end face of the connecting plate 44. The limiting block 45 is inserted into the limiting groove 410. The provision of the liquid supply unit 4 is not only conducive to storing lubricating liquid, but also has the advantage of being easy to disassemble and assemble, making it convenient to replenish the lubricating liquid into the tank body 41 later.

[0022] In this embodiment, the connecting plate 44 and the stopper 45 are integrally formed, and both have arcuate cross-sections. This integral structure enhances structural integrity and stability, while the arcuate design facilitates the connection plate 44 and the stopper 45 to conform to the outer wall of the can body 41 and the outer wall of the stopper groove 410, respectively.

[0023] In this embodiment, the cross-section of the fixing frame 40 is U-shaped, and the fixing frame 40 is fixedly connected to the mounting frame 20 by bolts. The U-shaped design provides good support and stability, and the bolt fixing method ensures the installation stability between the fixing frame 40 and the mounting frame 20.

[0024] In this embodiment, two connecting rods 43 are fixed to the rear end surface of the connecting plate 44. The connecting rods 43 pass through the fixing frame 40 and are slidably connected to the fixing frame 40. The connecting rods 43 guide the horizontal movement of the fixing frame 40, ensuring the stability and smoothness of the horizontal movement of the fixing frame 40.

[0026] In this embodiment, support rods 15 are fixed at the four corners of the bottom of the base 10. A mounting base 16 is fixed between the bottom ends of two adjacent support rods 15. Both ends of the mounting base 16 have mounting holes 160. The design provides a bolt-on installation method, which facilitates fixing the device to different types of floors.

[0027] In this embodiment, two hanging plates are fixed to the inner top of the transmission chamber 200, and the elbow 27 passes through the hanging plates and is fixed to the hanging plates by bolts. This design ensures the stability and position accuracy of the elbow 27 and reduces displacement caused by vibration or external force.

[0028] In this embodiment, the top of the base 10 is provided with a strip-shaped groove 13, above which a guide rod 14 is fixed. A connecting block 202 is fixed to the inner bottom of the mounting bracket 20. The connecting block 202 passes through the strip-shaped groove 13, and the guide rod 14 passes through the connecting block 202 and is slidably connected thereto. This design improves the stability and smoothness of the horizontal movement of the mounting bracket 20, thereby ensuring the stability of the horizontal movement of the camera 3.

[0029] It should be added that the left and right side walls of the mounting frame 20 in this embodiment are fixedly connected with side plates 24 by bolts. The side plates 24 protect the gears 22 and other structures in the mounting frame 20, ensuring the stable movement of the gears 22 and other structures.

[0030] It is worth noting that the motor 23, camera 3 and pump body 25 involved in this embodiment are existing conventional technologies and will not be described in detail here. During use, the user first turns on the power supply of the motor 23, and the motor 23 starts to work. The output shaft of the motor 23 rotates, driving the rotating shaft 21 and the gear 22 to rotate. The gear 22 rolls along the rack 12, and the gear 22 simultaneously drives the mounting frame 20 to move horizontally. The connecting block 202 slides along the guide rod 14, and the mounting frame 20 drives the camera 3 to move horizontally. When lubrication of the gear 22 and the rack 12 is required, the user first turns on the power of the pump body 25, and the pump body 25 starts to work. At this time, the lubricating liquid in the tank body 41 enters the discharge pipe 26 through the liquid inlet pipe 28, and enters the elbow 27 through the discharge pipe 26. Finally, the lubricating liquid is sprayed onto the gear 22 through the nozzle 270, and the gear 22 and the rack 12 can be lubricated. Example

[0031] See also Figure 6 As shown, the top of the cavity 201 is fixedly connected with a timing control module 2010 by bolts, and the timing control module 2010 is connected in series to the connecting wire between the pump body 25 and the power supply; It is worth noting that, by setting the timing control module 2010, it is convenient to start and close the pump body 25 at a fixed time, thereby conveniently delivering the lubricating fluid to the gear 22 for lubrication at a fixed time, thereby ensuring the stable operation between the gear 22 and the rack 12.
