Technical Field

[0001] This utility model relates to the technical field of sliding cover service vehicles, specifically a sliding cover service vehicle that can be raised and lowered. Background Technology

[0002] Sliding-cover service carts are common mobile auxiliary tools widely used in hospitals, restaurants, hotels, offices, and other locations. Their structure typically includes a body, a sliding cover, storage space, and casters. The sliding cover design not only prevents dust but also provides protection when not in use. Currently, most sliding-cover service carts on the market have a fixed height and lack height adjustment functionality. Due to varying heights of service personnel, operating a fixed-height cart can lead to discomfort at the operating angle, excessive bending, or raising of the arms. Prolonged use can exacerbate fatigue and reduce service efficiency. Therefore, there is an urgent need for a height-adjustable sliding-cover service cart to address these technical shortcomings.

[0013] (1) The vehicle is equipped with a cylinder, column, base, telescopic sleeve, slider, slide, box, and height adjustment bolt. The four corners of the vehicle are fixed by the connection between the cylinder and the column to adjust the height. When the height of the vehicle needs to be adjusted, loosen the height adjustment bolt in the box, grab the handle and lift the vehicle to the required position, and then tighten the height adjustment bolt. As the vehicle is raised, the telescopic sleeve at the bottom is pulled open and the slider slides to limit the vehicle and prevent the vehicle from falling out. The service vehicle can be adjusted in height as needed to suit different usage scenarios. For service personnel of different heights, it can reduce the fatigue of operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An embodiment of this utility model is provided: a liftable sliding cover service vehicle, including a base 6 and a column 5. The base 6 is welded with columns 5 at all four corners. A cylinder 4 is sleeved on the outside of the column 5. A vehicle body 1 is welded between the cylinders 4. A box 11 is fixedly connected to the outer wall of the cylinder 4. Multiple sets of fixing holes 15 are opened in the column 5. An adjusting bolt 12 is fixedly connected between the column 5 and the cylinder 4 through the fixing holes 15. The adjusting bolt 12 is located inside the box 11. The outer wall of the column 5 is processed with a protrusion 16. A reserved groove is opened on the inner wall of the cylinder 4 along its height direction. The protrusion 16 is embedded in the reserved groove. A sliding groove 10 is opened on each side of the bottom end of the vehicle body 1. A slider 9 is embedded in the sliding groove 10. A telescopic sleeve rod 8 is hinged between the slider 9 and the base 6. Two sets of telescopic sleeve rods 8 are provided. The two sets of telescopic sleeve rods 8 are symmetrically distributed about the vertical center line of the vehicle body 1.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the height of the vehicle body 1 is adjusted by connecting the four corners of the cylinder 4 and the column 5. When the height of the vehicle body 1 needs to be adjusted, loosen the height adjustment bolt 12 in the box 11, grab the handle 17 and lift the vehicle body 1 to the required position. The protrusion 16 is embedded in the reserved groove to ensure the stability of the lifting. Then tighten the height adjustment bolt 12. As the vehicle body 1 is raised, the telescopic sleeve 8 at its bottom is pulled open and cooperates with the sliding block 9 to limit the vehicle body 1 and prevent the vehicle body 1 from falling out.

[0024] The base 6 has four foot brake wheels 7 installed at the bottom corners, the vehicle body 1 has a handle 17 installed on one side, and the vehicle body 1 has multiple sets of slots 2. Each set of slots 2 has a partition 3 inserted into it, and the partitions 3 are evenly distributed.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, the vehicle body 1 is equipped with multiple sets of slots 2, and each set of slots 2 is connected to a set of partitions 3. Items can be retrieved directly by pulling out the partitions 3 without opening the top sliding cover 13 of the vehicle body 1, making mobile service convenient.

[0026] A lock hole 14 is provided on the upper front end of the vehicle body 1. A triangular rotating piece 19 is fixedly connected to one end of the lock hole 14. An arc-shaped groove is provided inside the triangular rotating piece 19. A front locking pin 20 is movably assembled on the triangular rotating piece 19 through the arc-shaped groove. Slide rails 18 are machined on the front and rear edges of the top of the vehicle body 1. Two sets of sliding covers 13 are slidably connected to the slide rails 18. A connecting rod 21 is provided on the top of the front locking pin 20. The connecting rod 21 is installed in the slide rail 18. A rear locking pin 22 is fixedly connected to the other end of the connecting rod 21.

[0027] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the vehicle body 1 locks the sliding cover 13 through the lock hole 14. During operation, the key inserted in the sliding cover 13 rotates, causing the triangular rotating piece 19 to rotate. The front locking pin 20 rises or falls under the action of the rotation of the triangular rotating piece 19. When the front locking pin 20 rises, the rear locking pin 22 falls under the action of the connecting rod 21. The front locking pin 20 rises to lock the connecting rod 21, and the rear locking pin 22 falls to lock the vehicle body 1, thereby locking the two sets of sliding covers 13 at the top of the vehicle body 1 at the same time.

[0028] Working principle: The height of the vehicle body 1 is adjusted by connecting the four corners of the cylinder 4 to the column 5. When the height of the vehicle body 1 needs to be adjusted, loosen the height adjustment bolt 12 inside the box 11, grasp the handle 17 to lift the entire vehicle body 1 to the required position, and then tighten the height adjustment bolt 12. As the vehicle body 1 rises, the telescopic sleeve 8 at its bottom opens and, together with the sliding block 9, limits the vehicle body 1 to prevent it from falling out. The service vehicle can be adjusted in height as needed to suit different usage scenarios. The vehicle body 1 is equipped with multiple sets of slots 2, and each set of slots 2 is fitted with a set of partitions 3. Without opening the top sliding cover 13 of the vehicle body 1, the partition 3 can be pulled out directly to retrieve items, facilitating mobile service. The vehicle body 1 locks the sliding cover 13 through the lock hole 14. During operation, the key inserted in the sliding cover 13 rotates, causing the triangular rotating piece 19 to rotate. The front locking pin 20 rises or falls under the action of the rotation of the triangular rotating piece 19. When the front locking pin 20 rises, the rear locking pin 22 falls under the action of the sliding cover 13. The front locking pin 20 rises to lock the connecting rod 21, and the rear locking pin 22 falls to lock the vehicle body 1, thereby locking both sets of sliding covers 13 at the top of the vehicle body 1 simultaneously, realizing one-step operation of the locking cover.
