Description

a medical bed

technical field

The invention relates to the technical field of medical instruments, in particular to a medical bed.

Background technique

When the doctor massages the child, he places the child on the medical bed. The existing medical bed cannot be moved, which greatly occupies the space of the narrow treatment room. This kind of medical bed cannot be retracted freely, is bulky, and cannot be folded, which makes the originally narrow treatment room crowded. In such an environment, doctors cannot concentrate on treating patients.

Contents of the invention

The object of the present invention is to provide a medical bed that can save space, can be retracted freely and can be folded.

The present invention is achieved through the following measures: a medical bed, including a turning device, a locking device and a folding bed arranged on the turning device;

The overturning device includes an attachment plate arranged on the wall, the attachment plate is provided with a track A, the track A is h-shaped, the track A includes a vertical main channel and a branch channel, and the main channel Racks are provided on the two side walls of the main channel, a slider is provided in the main passage, a gear meshing with the rack is provided at one end of the slider, and a connecting plate is provided at the other end of the slider. The connecting plate is L-shaped, and the connecting plate includes two folded edges, and the joint parts of the two folded edges are hinged with the slider, and a flange is provided at the bottom of one of the folded edges, and the flange is arranged on the In the branch channel, the folding bed is arranged on the other of the folded edges;

The folding bed includes a base plate, brackets, rails arranged between the brackets and a bed board fixedly connected to the rails, the brackets are symmetrically arranged on both sides of the bottom plate, and the rails include a first rail wood and the second fence, the first fence is hinged with the bracket, the railing of the first fence is provided with a gear A, the second fence is hinged with the first fence, the A motor A is arranged on the bottom plate, a gear B is arranged on the output shaft of the motor A, and the gear B meshes with the gear A;

The attachment plate is provided with the locking device, the locking device is arranged on one side of the main channel, the locking device includes a support plate, the support plate is fixedly connected with the attachment plate, the A limiting block is arranged on the support plate, and a spring is arranged at the bottom of the limiting block, and one end of the spring is fixedly connected with the attachment plate, and the other end is fixedly connected with the limiting block.

Beneficial effects of the present invention: the technical scheme of the present invention is designed based on the idea of saving space, freely retractable and foldable. In order to save the floor space of the treatment room and realize the free retractability, the present invention is arranged on the wall of the treatment room. The present invention does not occupy the floor space of the treatment room and can solve the problem of crowded treatment rooms. The overturning device, locking device and folding bed in the present invention are all attached to the attachment plate in the overturning device, so as long as the attachment plate is set at a reasonable height, the position of the folding bed can be adjusted, the adjustment is quicker and the disassembly is more convenient, and the attachment The board plays the role of pulling a hair and moving the whole body. An h-shaped track A is set on the attachment plate, and the folding bed can be adjusted from a vertical placement state to a horizontal placement state through the h-shaped track A, so that the folding bed can be fully opened later, and the track A is divided into a main channel and a branch channel. The slider is set in the main channel, and the main channel plays the role of bearing, fixing, guiding the slider and reducing its friction. It is used to control the linear reciprocating movement of the slider, and the flange on the connecting plate is limited in the branch channel, which can Control the movement of the flange along the movement track of the branch channel, and the branch channel mainly plays the role of changing direction, so that the connecting plate can be adjusted from the vertical state to the horizontal state centered on the hinge axis, and finally the folding bed can be adjusted from vertical to horizontal. Placed horizontally, in order to prevent the overturning device and the folding bed from falling due to its own gravity during the movement, a rack is set in the track A, and a gear is set on the slider. Since the tooth profile of the rack is a straight line, each point on the tooth profile has the same The pressure angle is equal to the inclination angle of the tooth profile, so the gravity of the turning device and the folding bed itself is distributed to the rack through the gear. When the folding bed is set at a reasonable height, the rack and pinion stops working, and the turning device and the self gravity of the folding bed are distributed to the locking device. The folding bed adopts the combination of crank connecting rod and gear, which can perform retraction movement without track.

Further, the attachment plate is provided with a groove, the support plate is arranged in the groove, and the end surface of the support plate is lower than the end surface of the attachment plate.

With the above further beneficial effects: a groove is provided on the attachment plate, the support plate is placed in the groove, and the end surface of the support plate is lower than the end surface of the attachment plate, so that the other edge of the connecting plate can be vertically After the direction is adjusted to the horizontal direction, it can still continue to rise until the folding bed is adjusted to a suitable position.

Further, the limiting block is cylindrical, and one end surface of the limiting block is an inclined plane.

Adopting the above further beneficial effects: one end of the limit block is set as a slope, and the slope is conducive to the continuous rise of the connecting plate without being blocked. When the connecting plate rises above the limit block, due to the action of the spring, the limit block is initially In the position state, since the limit block is an inclined plane, the inclined plane can prevent the connecting plate from sliding down.

Further, the spring is arranged in the groove.

The further beneficial effect of adopting the above is: the spring is arranged in the groove, the spring can make the limit block perform telescopic reciprocating movement, and the groove can limit the position of the spring.

Further, the bottom plate is fixedly connected to the other one of the folded edges of the connecting plate.

The further beneficial effect of adopting the above is: the base plate is provided with a folding bed, and the base plate and the connection plate are fixedly connected, and the movement of the other folding edge of the connection plate can drive the movement of the folding bed.

Further, the slider is provided with a motor B, and the output shaft of the motor B is provided with the gear.

The further beneficial effect of adopting the above is that the gears are driven to rotate by the motor B, and the motor B mainly generates driving torque as a power source for electrical appliances or various machines.

Further, the flange is arranged tangent to the branch channel.

The further beneficial effect of adopting the above is that the flange is arranged tangentially to the branch channel, which can ensure the smooth movement of the flange in the branch channel.
