[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 2 This invention provides an embodiment of a lifting platform with a sliding roof device. The sliding roof device includes a worktable 11 surrounded by guardrails. A support column 10 is fixedly installed inside the worktable 11, and a top plate 1 is fixedly installed on the top of the support column 10. A telescopic plate 2 is slidably installed inside the top plate 1. Mounting caps 3 are fixedly installed on both sides and in the middle of the top of the telescopic plate 2. Rotatable ball bearings 4 are installed inside the mounting caps 3. An opening is provided at the top of the mounting caps 3, through which the ball bearings 4 protrude. Mounting caps 3 and ball bearings 4 are also provided on the side walls of the telescopic plate 2 that contact the inner wall of the top plate 1. A telescopic groove is provided at the bottom of the top plate 1. Mounting caps 3 and ball bearings 4 are also provided on the bottom sides of the telescopic plate 2 that contact the top plate 1. By designing the ball bearings 4, the friction between the telescopic plate 2 and the top plate 1 changes from sliding to rolling, ensuring smooth lifting or opening / closing without jamming. This allows for immediate fulfillment of needs for sunshade, rain protection, or ventilation without waiting or repeated operation. Because of the use of rolling friction, the harsh noise generated by friction between parts is reduced, and only a slight running sound is produced during operation, which can keep the surrounding environment quiet, making it especially suitable for use in scenarios that require low noise.

[0020] Specifically, a fixed plate 8 and a limiting plate 7 are fixedly installed on both sides of the bottom of the top plate 1, and a screw 6 is rotatably installed between the fixed plate 8 and the limiting plate 7. A slider 9 is also fixedly installed at the bottom of the telescopic plate 2. The slider 9 is threadedly connected to the screw 6. A telescopic motor 5 is fixedly installed on the outside of the fixed plate 8. The output shaft of the telescopic motor 5 passes through the fixed plate 8 and is fixedly connected to the screw 6.

[0021] Understandably, the telescopic motor 5 operates, driving the screw 6 to rotate, which in turn moves the slider 9, thus extending and retracting the telescopic plate 2. During operation, the telescopic plate 2 needs to be extended to prevent falling objects from the top from hitting the workers on the workbench 11.

[0022] Specifically, a base plate 21 is provided below the workbench 11, and a lifting assembly is provided at the bottom of the workbench 11. The lifting assembly includes two hinge seats 12 fixedly installed at the bottom of the workbench 11, and two drive blocks 15 slidably installed on the base plate 21. Lifting arms 13 are connected to the hinge seats 12 and drive blocks 15 located diagonally. The two ends of the lifting arms 13 are rotatably connected to the hinge seats 12 and drive blocks 15 respectively. The two lifting arms 13 are cross-hinged together. A drive rod 16 is threadedly connected to the drive blocks 15. The drive rod 16 is a bidirectional screw. The two drive blocks 15 are threadedly connected to the two threaded sections of the drive rod 16. A baffle 19 is fixedly installed on the base plate 21. The two ends of the drive rod 16 are rotatably connected to the baffle 19. A partition plate 18 is provided in the middle of the drive rod 16. The baffle 19 and the partition plate 19 limit the movement of the drive blocks 15. A lifting motor 17 installed on the base plate 21 is fixedly connected to one end of the drive rod 16.

[0023] Furthermore, two sets of lifting components are symmetrically arranged, and a connecting rod 14 is rotatably connected between the lifting arms 13 of the two sets of lifting components. The connecting rod 14 connects the four lifting arms 13 together, realizing the synchronous lifting of the two sets of lifting components.

[0024] Specifically, the bottom of the base plate 21 is provided with wheels 20. Preferably, the wheels 20 are omnidirectional wheels. The bottom of the base plate 21 is provided with a locking mechanism. When the device moves to a fixed position, the wheels 20 can be locked by the locking mechanism to improve the safety of the device.

[0025] During use, the device is moved to the designated position, the operator enters the workbench 11, starts the lifting motor 17, the drive rod 16 rotates, causing the two drive blocks 15 to move closer to each other, the lifting arm 13 raises the workbench 11, and after reaching the height, the telescopic motor 5 starts, causing the screw 6 to rotate, which in turn drives the slider 9 to move, causing the telescopic plate 2 to extend, so as to protect the top of the workbench 11.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
