[0043] In a specific use process, when the position of the display 3 needs to be adjusted, the control button is triggered, the control unit unlocks the first brake and the second brake, and then the control unit controls the first motor and / or the second motor to automatically adjust the position of the display 3; or the position of the display 3 can be adjusted manually. When the position of the display 3 is manually adjusted, the pin 29 is initially at the first positioning point a, and then the two handles 27 are pulled to slide the two sliding frames 28, thereby causing each pin 29 to slide in the corresponding sub-slot 21101 until the pin 29 slides to the second positioning point b, at which time the pin 29 can be manually controlled. The handle 27 can adjust the position of the display 3 forward, upward, or downward; pull the two handles 27 to slide the two sliding frames 28, so that each pin 29 can slide in the corresponding sub-slot 21101 until the pin 29 slides to the third positioning point c, and then the handle 27 can be manually controlled to adjust the position of the display 3 backward, upward, or downward; after adjusting the display 3 to a suitable position according to needs, pull the two handles 27 to slide the pin 29 to the first positioning point a, and then push the handle 27 back to the back of the display 3, so as to achieve the purpose of hiding the handle 27 and make the doctor's operating trolley 1 look beautiful. In the process of manually adjusting the position of the display 3, the first screw rod and the second screw rod are adaptively rotated.

A connection seat 2701 is fixedly connected to the left and right ends of the vertical plate respectively, and the two connection seats 2701 are arranged in a mirror symmetric manner. The connection seat 2701 includes a vertical connection plate and a horizontal plate connected to the upper and lower ends of the vertical connection plate. The vertical connection plate is fixed to the vertical plate of the assembly frame 25. A first mounting groove is provided on the lower surface of the upper horizontal plate, and the first mounting groove is a cylindrical groove. A second mounting groove is provided on the upper surface of the lower horizontal plate, and the second mounting groove includes a first groove 27011 and a second groove 27012 that are connected. The cross section of the first groove 27011 is It is in the shape of an arc, and the cross-section of the second groove 27012 includes an arc, and the arc corresponding to the first groove 27011 and the arc corresponding to the second groove 27012 are concentric circles, and the diameter of the arc corresponding to the first groove 27011 is smaller than the diameter of the arc corresponding to the second groove 27012, and an arc-shaped limit block 27013 is provided in the second groove 27012, and the limit block 27013 and the first groove 27011 form a circumferentially open cylindrical groove, and limit grooves are respectively formed between the two ends along the circumference of the limit block 27013 and the two side walls of the second groove 27012, which are respectively recorded as the first limit groove 27014 and the second limit groove 27015.

[0046] The handle 27 includes a first handle portion 2702 and a second handle portion 2703 that are used together. The upper end of the first handle portion 2702 is provided with a cylindrical pin 27021, and the cylindrical pin 27021 is used to cooperate with the first mounting groove. The first handle portion 2702 can rotate freely relative to the first mounting groove; the upper end of the second handle portion 2703 is hollow to form a accommodating cavity, and the lower end of the first handle portion 2702 is inserted into the accommodating cavity of the second handle portion 2703, and a spring 2704 is provided in the accommodating cavity of the second handle portion 2703, and the two ends of the spring 2704 are respectively abutted against the lower end surface of the first handle portion 2702 and the bottom surface of the accommodating cavity of the second handle portion 2703.

[0047] A cylindrical pin 27031 with a boss is provided at the lower end of the second handle portion 2703. The cylindrical pin 27031 with a boss is inserted into the first groove 27011. When the boss is limited at one of the limiting grooves, the handle 27 is in a folded state, that is, the handle 27 and the vertical connecting plate of the connecting seat 2701 are not in the same plane, and the two are perpendicular to each other. At this time, the handle 27 is hidden behind the display 3, and the medical staff cannot manipulate the handle 27 to manually adjust the display 3. When the boss is limited at another limiting groove, the handle 27 is in an unfolded state, that is, the handle 27 and the vertical connecting plate of the connecting seat 2701 are in the same plane. At this time, the medical staff can manipulate the handle 27 to manually adjust the display 3.

[0048] In a specific use process, when the position of the display 3 needs to be adjusted, the control button is triggered, the control unit unlocks the first brake and the second brake, and then the control unit controls the first motor and / or the second motor to automatically adjust the position of the display 3; or the position of the display 3 can be adjusted manually. When the handle 27 needs to be manually operated, the second handle portion 2703 is lifted upward to disengage the boss from one of the limit grooves. At this time, the spring 2704 is compressed, and then the second handle portion 2703 is slowly rotated so that the boss moves along the limit groove. The first handle portion 2702 rotates along the upper surface of the limit block 27013, and during this process, the spring 2704 continuously applies a downward force to the second handle portion 2703. When the boss slides to another limit groove, the boss is clamped at another limit groove under the action of the spring 2704. At this time, the handle 27 is in an unfolded state. During the above process, the first handle portion 2702 rotates. When the handle 27 is in the unfolded state, the position of the display 3 can be adjusted by pulling the handle 27. During the process of manually adjusting the position of the display 3, the first screw rod and the second screw rod make adaptive rotations.

[0049] The display adjustment mechanism of the doctor's operating trolley involved in the present application can automatically or manually adjust the position of the display to obtain a more comfortable operating posture and meet specific usage requirements. When there is no need to manually adjust the display position, the handle involved in the present application can be hidden behind the display, making the appearance of the doctor's operating trolley beautiful.
