The control flange moves along the movement track of the branch channel, and the branch channel mainly plays the role of changing the direction, so that the other folded edge of the connecting plate is adjusted from the vertical state to the horizontal state, and finally the adjustment of the bed and chair from the vertical position to the horizontal state is realized. It is placed horizontally. In order to prevent the overturning device and the bed chair 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 rack profile is a straight line, all points on the profile have the same The pressure angle is equal to the inclination angle of the tooth profile, so the gravity of the turning device and the bed chair itself is dispersed to the rack through the gear. When the bed chair is set at a reasonable height, the rack and pinion stop working, and its turning device and the gravity of the bed chair are dispersed to the locking device. The bed chair is in the form of a crank connecting rod. Driven by the motor A, the bed chair can be adjusted to the form of a bed, and the bed chair can also be adjusted to the form of a chair, which is more convenient to adjust.

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

Using the above-mentioned further beneficial effects: a groove is provided on the attachment plate, the support plate is placed in the groove, and the end face of the support plate is lower than the end face of the attachment plate, so that the other folded edge of the connection plate can be vertically After the direction is adjusted to the horizontal direction, it can still continue to rise until the bed chair is adjusted to a suitable position.

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

The above-mentioned further beneficial effects are adopted: one end face of the limit block is set as an inclined plane, and the inclined plane 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 the initial 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.

A further beneficial effect of the above is that: the spring is arranged in the groove, the spring can make the limit block perform telescopic reciprocating motion, 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.

A further beneficial effect of the above is that: a bed chair is arranged on the bottom plate, and the bottom plate and the connecting plate are fixedly connected, and the movement of the bed and chair can be driven by the movement of another folded edge of the connecting plate.

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 tangentially to the branch channel.

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

Further, one end of the rotating shaft is provided with the movable pull rod, and the other end is provided with a motor A, and the output shaft of the motor A is connected with the rotating shaft through a coupling.

The further beneficial effects of the above are: the rotating shaft is driven to rotate by the motor A, and the motor A mainly generates driving torque as a power source for electrical appliances or various machines.
