[0023] See also Figure 4 and Figure 5 , an embodiment provided by the present invention: a cart for placing an oral scanner, wherein a storage component is fixedly installed at the bottom of the outer wall of the lifting platform 11, and the storage component is movably installed at the bottom of the inner wall of the main box body 4; The storage assembly includes: a double-headed adjusting screw 27, a lifting rod 25 and a positioning shaft 24; A double-headed adjusting screw 27 driven by a servo motor is installed at the bottom of the inner wall of the main box body 4, and a sliding block 26 is sleeved on the outer wall of the double-headed adjusting screw 27, and the sliding block 26 is rotated and limited by a limit slide bar fixedly installed on the side of the inner wall of the main box body 4, and a lifting rod 25 is movably installed on the top of the outer wall of the sliding block 26 through a hinge, and the positioning shaft 24 passes through the lifting rods 25 and is fixedly connected, and the top of the outer wall of the lifting rod 25 is fixedly connected to the bottom of the outer wall of the lifting platform 11 through a hinge; A telescopic sleeve 28 is movably mounted on the outer wall side of the main box body 4, a tool box 6 is fixedly mounted on the outer wall side of the telescopic sleeve 28, a slide rail 29 is fixedly mounted inside the tool box 6, a drawer box 30 is movably mounted on the slide rail 29 via a pulley, and the drawer box 30 is used to store oral examination tools; A second fixing frame 9 is fixedly mounted on the front side of the outer wall of the main box body 4, and a fill light 10 is fixedly mounted on the side of the outer wall of the second fixing frame 9; Further, the double-headed adjusting screw 27 driven by the servo motor is started, and the double-headed adjusting screw 27 drives the sliding block 26 to move relative or oppositely, and the sliding block 26 drives the lifting rod 25 to unfold or cross-fold around the positioning shaft 24 through the hinge, and the lifting rod 25 pushes the lifting platform 11 to move up and down through the hinge. The lifting platform 11 moves up and down to store or extend the oral scanner 5 installed on the rotating table 12 inside and outside the main box 4. When the oral scanner 5 is needed to work, the oral scanner 5 is extended, and when it is used, the oral scanner 5 is stored in the main box 4 to prevent the oral scanner 5 from being damaged by external collisions, thereby improving the safety and life of the equipment; A drawer box 30 is movably installed in the tool box 6 through a slide rail 29 and a pulley. When medical staff examine the oral cavity, they can pull out the drawer box 30 from the tool box 6 to facilitate the placement of oral examination tools. The telescopic sleeve 28 can be telescoped left and right. When moving and storing the equipment, the tool box 6 is stored on the side of the main box 4, which reduces the space occupied by the equipment, reduces the size of the equipment, and prevents the equipment from falling and being damaged due to collision. The fill light 10 installed on the second fixing frame 9 plays a fill light role, providing sufficient light when examining the oral cavity, so that medical staff can use the oral scanner 5 to perform a comprehensive scanning examination of the patient's oral cavity.

[0024] See also Figure 6 and Figure 7 , an embodiment provided by the present invention: a cart for placing an oral scanner, wherein a hydraulic lifting and adjusting component is fixedly installed at the bottom of the inner wall of the base 1, and the hydraulic lifting and adjusting component is used to adjust the height of the main box 4 in real time; The hydraulic lifting and adjusting assembly includes: a PLC relay switch 7, a first hydraulic pump 32 and an electronic one-way valve 34; A hydraulic box 31 is fixedly installed at the bottom of the inner wall of the base 1, a first hydraulic pump 32 is fixedly installed at the bottom of the inner wall of the hydraulic box 31, a PLC relay switch 7 is fixedly installed at the top of the outer wall of the base 1, and the PLC relay switch 7 is connected to the first hydraulic pump 32 through a power signal line, a boosting channel 33 is fixedly installed at the top of the outer wall of the hydraulic box 31, a servo motor-driven electronic one-way valve 34 is fixedly installed on the side of the inner wall of the boosting channel 33, and the servo motor-driven electronic one-way valve 34 is connected to the PLC relay switch 7 through a power signal line, and a second adjusting column 2 is fixedly installed at the top of the outer wall of the boosting channel 33; A hydraulic groove is provided inside the second adjusting column 2, and the first adjusting column 3 is installed in the hydraulic groove; Further, when the medical staff needs to raise the height of the oral scanner 5, by stepping on the PLC relay switch 7, the PLC relay switch 7 starts the first hydraulic pump 32, and the first hydraulic pump 32 pumps the hydraulic oil in the hydraulic box 31 into the boosting channel 33. At this time, the PLC relay switch 7 starts the electronic one-way valve 34 to rotate and become a valve that opens upward. The hydraulic oil in the boosting channel 33 enters the hydraulic groove in the second adjusting column 2 through the electronic one-way valve 34. The pressure of the hydraulic oil in the hydraulic groove lifts the first adjusting column 3 and raises the oral scanner 5 to a certain height. When the height is adjusted to the height required by the medical staff, the medical staff steps on the PLC relay switch 7 again to cut off the power. At this time, the electronic one-way valve 34 stores the hydraulic oil in the second adjusting column 2. The pressure of the hydraulic oil ensures that the height of the first adjusting column 3 remains unchanged. When the height of the oral scanner 5 needs to be lowered, the PLC relay switch 7 is stepped on, and the PLC relay switch 7 starts the electronic one-way valve 34 to rotate and become a valve that opens downward. At this time, the hydraulic oil in the second adjusting column 2 and the boosting channel 33 flows back to the hydraulic box 31 through the electronic one-way valve 34. At this time, there is no more pressure support of hydraulic oil in the hydraulic empty groove in the second adjusting column 2. At this time, the first adjusting column 3 slowly descends in the second adjusting column 2; The height adjustment and fixation of the oral scanner 5 are realized without manual raising and lowering, which saves the operation time of medical staff and ensures that the hands of medical staff are in sterile conditions without direct contact with the equipment, thereby improving the safety and hygiene of oral examination.

Medical staff can quickly move the placement cart to the corresponding area for operation. When the placement cart moves to the fixed area, the second hydraulic pump 37 is started. The second hydraulic pump 37 uses the hydraulic oil pressure to determine the hydraulic telescopic rod 38. The hydraulic telescopic rod 38 extends, and the hydraulic telescopic rod 38 drives the fixed seat 39 to extend to the ground. An adsorption plate is installed on the surface of the fixed seat 39, so that the fixed seat 39 is firmly adsorbed on the ground, ensuring the stability of the placement cart. The placement cart is prevented from moving and tipping over due to collision and vibration, thereby improving the safety and service life of the equipment.

[0027] Working principle: first, the first adjustment column 3 is raised to a fixed height by stepping on the PLC relay switch 7, and then the oral scanner 5 is raised from the main box 4 through the storage component to prepare for oral scanning, and the oral scanner 5 is adjusted to the required scanning height through the hydraulic lifting adjustment component; Then, the circumferential angle and the pitch angle of the oral scanner 5 are adjusted by the second motor 35 and the pitch angle adjustment assembly to ensure a full range of scanning of the patient's oral cavity; Finally, after the oral examination is completed, the oral scanner 5 is stored in the main box 4 through the storage assembly, and then the placement cart is fixed by the fixing seat 39 to ensure the stable storage of the placement cart.
