Problems solved by technology
[0005] The disadvantages of the above-mentioned angle measuring mechanism are that, firstly, it is installed inside the seat arm 1 and the back plate arm 10, and the installation space is narrow and inconvenient to operate, resulting in time-consuming installation and inconvenient maintenance; secondly, the angle measuring mechanism is difficult to adjust to zero. position (the back plate and the seat plate are at zero position, and the angle measured by the potentiometer should be zero at this time), due to installation errors or the aging and deformation of the pull rope, the zero position will deviate. The control of the plate angle is inaccurate, which is not conducive to the smooth progress of the operation

The invention discloses a back plate angle measuring mechanism of an operation table. The back plate angle measuring mechanism comprises a hollow shaft (5) connected between a seat plate arm (1) and aback plate arm (10), a fixation assembly (2) connected to the seat plate arm (1), a clamping assembly (4) connected to the back plate arm (10), and a potentiometer (3) connected to the fixation assembly (2). The potentiometer (3) includes a measuring shaft (31), wherein the measuring shaft and the hollow shaft (5) are in a coaxial line state. The clamping assembly (4) clamps the measuring shaft (31). According to the invention, the measuring shaft can rotate by using a slot type screwdriver through the hollow shaft, so that the potentiometer is adjusted conveniently. The mechanism can be mounted on the outer sides of the seat plate arm and the back plate arm and is convenient to operate, mount or dismount.
Description
technical field [0001] The invention relates to a medical operating bed, in particular to a mechanism for measuring the angle of the backboard of the operating bed. Background technique [0002] The operating bed is an essential auxiliary tool for the surgical operation and diagnosis of various parts of the human body in the operating room of the hospital. Since the patient is anesthetized and unable to move, the doctor's position requirements for the patient are all controlled by the operating bed. of. The rotation angle of the backboard of the existing operating bed is usually measured by a potentiometer. [0003] Such as Figure 1 to Figure 3 As shown, the operating bed usually includes a seat board and a back board, wherein the seat board is installed on the seat board arm 1 , and the back board is installed on the back board arm 10 , and the two are connected by a rotating shaft 11 so that they can rotate with each other. The backplane angle measuring mechanism in the...
