[0027] The flip cover device 3 includes an L-shaped plate 31. The L-shaped plate 31 is fixedly connected to the upper left end of the full flip cover centrifuge 1. The front left end of the L-shaped plate 31 is fixedly connected to a motor 32. The L-shaped plate 31 facilitates the installation and fixation of the motor 32.

[0028] The right end output shaft of the motor 32 is fixedly connected to a turntable 33. The upper right end of the turntable 33 is rotatably connected to a rotating rod 34. The rear right end of the rotating rod 34 is rotatably connected to a moving rod 35. The moving rod 35 facilitates driving the inner tooth plate of the gear and tooth plate member 37 to move.

[0029] The moving rod 35 penetrates through the limiting block 36 and is slidably connected to its interior. The back of the moving rod 35 is fixedly connected to a gear and tooth plate member 37. The front end of the bottom of the inner tooth plate of the gear and tooth plate member 37 is fixedly connected to a first fixing block 38. The first fixing block 38 facilitates the installation and fixation of the spring 39.

[0030] The front end of the first fixing block 38 is fixedly connected to a spring 39. Resistance strain gauges 310 are adhesively connected to the spring 39 in the directions of the spring wire axes at ±45°. The resistance strain gauges 310 facilitate calculating the length change of the spring 39.

[0031] The front end of the spring 39 is fixedly connected to a second fixing block 311. The left end of the turntable 33 is rotatably connected to the front right end of the L-shaped plate 31. The turntable 33 and the rotating rod 34 are eccentrically arranged. The turntable 33 facilitates driving the rotating rod 34 to perform circular motion.

[0032] The resistance strain gauges 310 are electrically connected to an external electrical conversion device. The left end of the limiting block 36 is fixedly connected to the center of the right end of the L-shaped plate 31. The inner tooth plate of the gear and tooth plate member 37 is slidably connected to the L-shaped plate 31. The limiting block 36 facilitates the limiting movement of the moving rod 35.

[0033] The inner gear of the gear and tooth plate member 37 is rotatably connected to the L-shaped plate 31. The right end of the inner gear of the gear and tooth plate member 37 is fixedly connected to a cover plate 2 through a gear rod.

[0034] The working principle of the flip cover device of a full flip cover centrifuge based on Embodiment 1 is as follows:

[0035] First, when automatic flip cover needs to be realized, the motor 32 is started. The motor 32 drives the turntable 33 to rotate. The turntable 33 drives the rotating rod 34 to perform circular motion through eccentric arrangement. The rotating rod 34 drives the moving rod 35 to move forward in the limiting block 36. The moving rod 35 drives the inner tooth plate of the gear and tooth plate member 37 to move forward. The inner tooth plate of the gear and tooth plate member 37 drives the inner gear of the gear and tooth plate member 37 to rotate. The inner gear of the gear and tooth plate member 37 drives the cover plate 2 to rotate through a gear rod, realizing automatic flip cover, so as to facilitate maintenance personnel to inspect and repair the full flip cover centrifuge 1 and improve the use efficiency of the full flip cover centrifuge 1;

[0036] Second, energize the spring 39 through an external cable. During the movement of the inner tooth plate of the gear and tooth plate assembly 37, the spring 39 is driven to contract, and a stress field is generated around it. This stress field will affect the resistance value of the resistance strain gauge 310. Then, the resistance strain element inside the resistance strain gauge 310 deforms under the action of stress, and the change in the length of the spring 39 is calculated through the resistance value of the resistance strain gauge 310, thereby indirectly judging the rotation angle of the cover plate 2 and improving the safety and stability of the fully flip-open centrifuge 1.

[0037] Embodiment 2:

[0038] Please refer to Figure 4 , for a flip-open device of a fully flip-open centrifuge of the present utility model. Compared with Embodiment 1, this embodiment further includes: a detection mechanism 4. The detection mechanism 4 includes a pressure sensor 41, and the pressure sensor 41 is fixedly connected to the top of the cover plate 2.

[0039] A sealing ring 42 is adhesively connected to the bottom of the cover plate 2, a contact rod 43 is fixedly connected to the left end of the bottom of the cover plate 2, and a control switch 44 is fixedly connected to the upper left end inside the fully flip-open centrifuge 1. The control switch 44 is convenient for controlling the operation of the pressure sensor 41.

[0040] The control switch 44 is electrically connected to the pressure sensor 41, and the pressure sensor 41 is electrically connected to an external display screen.

[0041] In this embodiment:

[0042] When the cover plate 2 rotates downward, the cover plate 2 drives the contact rod 43 to move downward. The contact rod 43 squeezes the control switch 44, causing the control switch 44 to control the operation of the pressure sensor 41. And when the contact rod 43 squeezes the control switch 44, the cover plate 2 completes the downward rotation action. Then, the pressure sensor 41 detects the pressure inside the fully flip-open centrifuge 1. The pressure sensor 41 transmits an electrical signal to the external display screen, and the staff judges whether there is a leakage problem in the fully flip-open centrifuge 1 based on the pressure inside the fully flip-open centrifuge 1. When it is found that there is a leakage problem in the fully flip-open centrifuge 1, the staff replaces the sealing ring 42 to prevent the medium inside the fully flip-open centrifuge 1 from leaking into the external environment, causing waste of resources and affecting the surrounding environment and the normal operation of the fully flip-open centrifuge 1.
