Automatic-control elevating mechanism for bed

Abstract

The invention provides an automatic-control elevating mechanism for a bed. The automatic-control elevating mechanism comprises upper supports, columns, lower supports, rotary shafts of the elevating mechanism, a connecting rod, an electric push rod, a motor, optoelectronic switches and a photoelectric controller. The upper support is fixedly connected with a bed plate. The columns are located among the upper supports and the lower supports. Two ends of each column are rotatably connected with one upper support and one lower support. The lower supports are fixedly arranged to a bed frame. Each rotary shaft of the elevating mechanism is located between one column and one lower support. Two ends of each rotary shaft are fixedly connected with two columns. The electric push rod is movably connected with one swing rod. The swing rods are fixedly connected with the rotary shafts of the elevating mechanism. The connecting rod is connected with the rotary shafts of the elevating mechanism in order to keep the mechanism to elevate synchronously. The optoelectronic switches and the motor are connected with the photoelectric controller. The motor is connected with the electric push rod. The automatic-control elevating mechanism for the bed has following beneficial effects: the electric push rod is used for adjusting height of a bed body; only by shielding and breaking off photoelectric control circuits on either side around a treatment bed, height adjustments can be made; and only by treading any foot-controlled pedal on two sides of the treatment bed, the bed can move horizontally in a convenient and rapid mode.

Description

technical field [0001] The invention specifically relates to an automatic control lifting mechanism for a bed, which belongs to the field of medical equipment manufacturing. Background technique [0002] In order to make it easier for patients to sit or doctors to diagnose and treat patients, there is usually a lifting mechanism around the bed frame to adjust the height and inclination of the bed. At present, the common lifting mechanism is to install one or two manual buttons or feet at the head or end of the bed. During the operation, the doctor needs to stop the work at hand to press the manual button; or for some doctors, such as orthopedics and massage, they often need to run around because they often perform complex operations or manipulations at different positions on the bed. Step on the corresponding foot pedal to control the lifting of the bed. These methods will increase the complexity of the doctor's work, affect the accuracy of the operation or technique, and ar...

Problems solved by technology

When working, the translation of the bed body cannot be realized quickly. Every time before the bed body needs to be moved, the operator needs to stop the work at hand, step on the control pedals at the four bed legs respectively, and put down the four wheels one by one. To realize the movement of the whole bed, after the movement is completed, the four wheels must be fixed one by one, which is time-consuming and labor-intensive
