Detailed Description

A vertical lifting invisible bed is composed of a driving part and a bed body part.

Wherein the driving part uses a tubular motor as a driving motor 1, the motor 1 is arranged on a ceiling, one end of four traction belts 3 is respectively arranged on the motor 1, the other end of the four traction belts hangs down through four self-locking pulleys 2 arranged on the ceiling respectively and is connected on a traction belt connecting rod 14 in the self-locking pulley 2 after bypassing a movable pulley 9 arranged on a bedstead 7.

The self-locking pulley 2 is a mechanism with the function of automatically locking the traction belt after exceeding the load, and is divided into an inclined groove type and a cam type according to the structure.

The structure of the chute type self-locking pulley is as follows: a fixed pulley 18 is arranged between two fixed frames 10 for fixing on a ceiling, a fixed plate 13 and a sliding plate 15 are arranged below the fixed pulley 18, and the traction belt 3 passes through a gap between the fixed plate 13 and the sliding plate 15 after passing through the fixed pulley 18. The fixed plate 13 is directly fixed on the fixed frame 10, the sliding plate 15 is provided with two guide rollers 11, the two fixed frames 10 are provided with inclined guide grooves 12, the guide rollers 11 can slide up and down in the guide grooves 12, and the sliding plate 15 can change the clearance with the fixed plate 13 when sliding up and down due to the action of the guide grooves 12. The sliding plate 15 is controlled by two driving arms 17 provided with springs 16 to slide downwards, a traction belt fixing rod 14 is arranged on the sliding plate 15, and one end of the traction belt 3 is fixed on the traction belt connecting rod 14 upwards after bypassing the movable pulley 9.

The structure of the cam self-locking pulley is as follows: a fixed pulley 18 is arranged between two fixed frames 10 for fixing on the ceiling, a fixed plate 13 and a cam 19 are arranged below the fixed pulley 18, and the traction belt 3 passes through the fixed pulley 18 and then passes through a gap between the fixed plate 13 and the cam 19. The fixed plate 13 is directly fixed on the fixed frame 10, the shaft 22 of the cam 19 is fixed on the fixed frame 10, and the clearance between the cam 19 and the fixed plate 13 can be changed by the rotation of the cam 19 around the shaft. The cam 19 is controlled by the spring 16 to rotate, a traction belt fixing rod 14 is arranged on the cam 19, and one end of the traction belt 3 is wound around the movable pulley 9, upwards and then fixed on the traction belt connecting rod 14.

Wherein the bed body part consists of a bed frame 7, a bed surrounding 5 and a mattress 4. Four pulleys are installed as movable pulleys 9 on the frame of the bed frame 7 at positions corresponding to the ceiling self-locking pulleys 2. The four angular positions of the bedstead 7 are provided with sleeves 8, bed legs 6 are arranged in the sleeves 8, the bed legs 6 can slide up and down in the sleeves 8, and the bed legs 6 are provided with upper positioning pins 21 and lower positioning pins 20. The bed frame 7 is provided with bed surrounds 5 around, and the bed surrounds 5 are connected with the bed legs 6 and can move up and down along with the bed legs 6.

When the bed is used in the air, the bed body is lifted by the four traction belts 3 through the motor 1, the self-locking pulley 2 and the movable pulley 9, the weight (about 30-60 KG) of the bed body is shared by the eight traction belts, when a person is not in the bed, the sliding plate 15 or the cam 19 cannot be pulled downwards because the acting force of the traction belts 3 connected to the sliding plate 15 or the cam 19 is smaller than the counter-acting force of the spring 16, and the traction belts 3 can freely penetrate through the sliding plate 15 or the cam 19 and the fixed plate 13 by enough distance, so that the motor 1 can drive the bed body to move up and down. After a person gets on the bed, the force acting on the sliding plate 15 or the cam 19 is larger than the counter force of the spring 16 due to the increase of the weight, the sliding plate 15 slides downwards or the cam 19 rotates downwards, the gap between the sliding plate 15 or the cam 19 and the fixed plate 13 is reduced due to the action of the guide groove 12 or the cam shaft 22, the traction belt 3 clamped between the sliding plate 15 or the cam 19 and the fixed plate is clamped, at the moment, all the force on the bed body only acts on the four self-locking pulleys 2 on the ceiling, the motor 1 is not stressed any more, and the damage to the motor 1 due to the increase of the weight of. When the bed is lifted after use, the weight of the bed body after the prisoner gets off the bed is reduced, and under the action of the lifting of the spring 16 and the traction belt 3, the sliding plate 15 moves upwards or the cam 19 rotates upwards, so that the traction belt 3 is not clamped any more, and the bed body can be lifted by the motor 1.

When the bed leg support is used, the bed body is lowered to a certain height, the motor 1 is stopped, the lower positioning pin 20 of the bed leg 6 is positioned at the upper part of the sleeve 8, the lower positioning pin 20 is controlled by hands to enable the bed leg 6 to fall until the sleeve 8 is positioned at the upper part of the upper positioning pin 21, the bed leg 6 extends downwards to the lower part of the bed frame 7 to form a support bed leg, and the other three bed legs 6 are sequentially carried out to finish the downward extending action of the bed leg. The bed mattress 4 is exposed from the bed periphery 5 when the bed periphery 5 descends together with the bed legs 6, and the motor 1 is started to make the bed body fall on the ground.

When the bed is lifted, the motor 1 is started to lift the bed to a certain height, and then the bed is stopped, the upper positioning pin 21 is controlled by hands, and the bed leg 6 is lifted upwards until the sleeve 8 is positioned at the lower part of the lower positioning pin 20, at the moment, the upper part of the bed leg 6 is positioned above the bed frame 7 and is basically consistent with the height of the mattress 4, the prisoner fence 5 is connected with the bed leg 6, and the fence 5 is also lifted upwards to enclose the mattress 4. When all four legs 6 are raised, the motor 1 is activated to raise the bed to the ceiling.

The telescopic leg lifting bed with the structure has the advantages of simple structure, convenience in operation, multiple functions and beautiful appearance, and is particularly suitable for being quickly installed and used in common families.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
