DETAILED DESCRIPTION

[0019] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 4In the embodiment of the utility model, a scanning bed with a telescopic outer cover structure includes a telescopic cover composed of a fixed sleeve 1, a telescopic sleeve 2, and a connecting sleeve 3, and the fixed sleeve 1, the telescopic sleeve 2 and the connecting sleeve 3 are connected to each other, and the top of the connecting sleeve 3 is fixedly connected to a fixed bed 4, the telescopic sleeve 2 is connected to the inner wall of the fixed sleeve 1 by sliding up and down, and the connecting sleeve 3 is connected to the inner wall of the telescopic sleeve 2 by sliding up and down;

[0021] It also includes a sliding block 8, and the inner walls of the telescopic sleeve 2 and the fixed sleeve 1 are provided with a vertical groove 5 for the sliding block 8 to slide up and down;

[0022] The interior of the sliding block 8 is connected to a lubrication mechanism connected to an oil pump, and the lubrication mechanism is used to reduce the friction force of the sliding block 8 when it moves up and down on the inner wall of the vertical groove 5 .

[0023] In this embodiment: when the lifting device drives the fixed bed 4 to lift, the telescopic cover is lengthened or shortened, and the telescopic cover as a whole protects the lifting device, and the up and down movement of the fixed bed 4 can assist patients of different body sizes to perform CT scanning. During the movement of the telescopic cover, the lubrication mechanism can reduce the relative sliding friction of the fixed sleeve 1, the telescopic sleeve 2, and the connecting sleeve 3, avoiding abnormal noise problems caused by excessive friction.

[0024] Please refer to Figure 4 The lubrication mechanism includes an oil groove 11 opened in the wide body of the sliding block 8, and the bottom end surface of the oil groove 11 is formed with an inclined guide surface 12. An inclined oil guide pipe 13 is opened inside the narrow body of the sliding block 8, and the liquid inlet of the oil guide pipe 13 is located at the low point end of the inclined guide surface 12. A ball groove 9 connected to the output end of the oil guide pipe 13 is opened on the narrow body end surface of the sliding block 8, and a ball 10 is slidably connected to the inner wall of the ball groove 9.

[0025] In this embodiment: the lubricating liquid in the oil groove 11 enters the oil guide pipe 13 in an inclined state through the guidance of the inclined guide surface 12, and when the fixed sleeve 1, the telescopic sleeve 2, and the connecting sleeve 3 slide against each other, the ball 10 contacts the inner wall end surface of the vertical groove 5, so the ball 10 will rotate in the process of moving with the telescopic sleeve 2 and the connecting sleeve 3, and the rotating ball 10 contacts the lubricating oil in the oil guide pipe 13, and the rotating ball 10 brings out the lubricating oil, and the lubricating oil brought out is attached to the vertical groove 5, thereby further reducing the friction force when the ball 10 rotates, avoiding the abnormal noise problem of the telescopic cover caused by the large friction force during use.

[0026] Please refer to Figure 4A connecting groove 15 is vertically opened inside the wide body of the sliding block 8, and the connecting groove 15 is connected to the inner cavity of the oil groove 11. A one-way valve 16 is installed on the wide body part of the connecting groove 15 through a mounting frame. The output end of the one-way valve 16 is connected to an oil inlet pipe 14 fixedly connected to the inner wall of the narrow body of the connecting groove 15, and the input end of the one-way valve 16 is connected to a bellows 17 connected to the oil pump.

[0027] In this embodiment: when the lubricating oil in the oil tank 11 is insufficient, the oil pump is started to pump the lubricating oil into the oil tank 11. The one-way valve 16 can prevent the lubricating oil in the oil tank 11 from flowing back. In the sliding process of the telescopic sleeve 2 and the connecting sleeve 3 of the telescopic cover, the bellows 17 is stretched or stretched accordingly, and the pipeline will not be compressed and bent, resulting in poor oil supply.

[0028] Please refer to Figure 2 and Figure 3 The top and bottom ends of the inner walls of the fixed sleeve 1 and the telescopic sleeve 2 are integrally formed with a limiting portion 6 protruding inward.

[0029] In this embodiment, the limiting portion 6 protrudes inwardly to limit the maximum distance of upward or downward movement of the telescopic sleeve 2 and the connecting sleeve 3.

[0030] Please refer to Figure 2 and Figure 3 The bottom ends of the outer walls of the telescopic sleeve 2 and the connecting sleeve 3 are integrally formed with an anti-slip portion 7 protruding outward, and the sliding block 8 is integrally formed with the outer wall of the anti-slip portion 7.

[0031] In this embodiment, the limiting portion 6 is used to limit the moving range of the anti-detachment portion 7, so as to prevent the fixing sleeve 1 from being separated from the telescopic sleeve 2, and the telescopic sleeve 2 from being separated from the connecting sleeve 3.

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
