Device for protecting rotation of clamping-slot type back plate of operating bed

Abstract

The invention relates to a device for protecting the rotation of a clamping-slot type back plate of an operating bed, wherein a main body comprises a back plate and a sitting plate which are rotationally connected through a rotating shaft; a hydraulic cylinder is arranged in the sitting plate; and a projecting shaft at the front end of the hydraulic cylinder is connected with the back plate through a connecting shaft. The device is characterized in that: a bending protective cover is arranged at the outer side of the connect joint of the back plate and the sitting plate; screw holes are arranged at two sides of one end of the protective cover; screws are used in the screw holes in a matching way to for fixing the protective cover on the back plate; and a U-shaped open slot is arranged in the middle of the other end of the protective cover. When the back plate is regulated, the open slot below the protective cover is used for preventing the back plate from mechanic interference with the projecting shaft at the front part of a piston rod of the hydraulic cylinder in a stretching process; and the parts and the components in the sitting plate are wrapped by the protective cover so that foreign matters are prevented from entering the sitting plate, so that the interior cleanliness is guaranteed and an aesthetic effect is achieved.

Description

technical field [0001] The invention relates to a protection device for a rotation part of an operating bed, in particular to a rotation protection device for a slot-type backboard of an operating bed. Background technique [0002] At present, the connection between the overall backboard of the operating bed and the seat board is connected through a rotating shaft, and the rotating connection is exposed to the outside to avoid mechanical interference with the piston rod of the hydraulic cylinder during the expansion and contraction process. The angle between the backboard of the operating bed and the seat board is adjusted by a hydraulic cylinder. During operation, the angle range is -40°-70°. When the angle of the backboard is between 0°-70°, an open gap appears at the connecting joint. And this gap is the position that the operator's hand can touch, if the backboard moves down again at this time, the operator will be pinched and cause injury, and the joint is exposed to th...

The angle between the backboard of the operating bed and the seat board is adjusted by a hydraulic cylinder. During operation, the angle range is -40°-70°. When the angle of the backboard is between 0°-70°, an open gap appears at the connecting joint. And this gap is the position that the operator's hand can touch, if the backboard moves down again at this time, the operator will be pinched and cause injury, and the joint is exposed to the outside, which is easy to cause dust, surgery, etc. Foreign matter such as blood in the body enters, causing internal mechanical wear and affecting the overall appearance
