Abstract

The utility model discloses an automatic lifting bed with a safety device, comprising a bed body (1) and a bed body lifting mechanism, wherein the bed body lifting mechanism is positioned between a floor and a ceiling, is matched with the bed body and is provided with an electric driving control device. The ceiling is provided with a limit switch (2) at the position corresponding to the bed body (1), and the bed body lifting mechanism is also provided with a limit-position limit switch (4). The limit switch (2) is connected with the electric driving control device and limit boards (3), and the size of the limit boards (3) is corresponding to the bed surface of the bed body (1). In the lifting or declining process of the bed body, when the bed body or an object on the bed body hits the limit board on the ceiling or an object under the bed body hits the limit board under the bed body, the limit switch cuts off a power supply, a motor stops rotating, and the bed body also stops moving, thereby ensuring the safety of persons and goods.

Description

A kind of automatic lifting bed with safety device

Technical field

The utility model relates to a kind of automatic lifting bed, especially a kind of automatic lifting bed with safety device.

Background technology

Current, a variety of lifting beds are arranged, the lifting bed of electronic control is more, and its kind of drive that realizes elevating function also has a lot.Chinese patent 200720078348.8 discloses a kind of indoor activity dividing plate, comprises dividing plate, lowering or hoisting gear, support, rope traction device, and its lowering or hoisting gear comprises gear, pulley, steel wire rope.Chinese patent 02115520.8 discloses a kind of suspension lifting bed, comprise bed head frame, pallet, cabinet base frame, elevating mechanism, be fixed with nut-screw mechanism on the bed head frame, the nut kink is on elevating bracket, two steel wire ropes are being fixed in the elevating bracket both sides, on the cabinet base frame of both sides, nut makes elevating bracket lifting pulling steel wire rope by frictional force to steel wire rope, thereby bed head frame is moved up and down by two suspended on the bed head frame.The disclosed a kind of lifting bed of Chinese patent 01143905.X, it is a kind of lifting bed with bedstead of at least two stent support, each support all is supported in vertical guide rail movably, can mobile in vertical direction bedstead.Chinese patent 02281488.4 disclosed lifting bed, comprise tabular bed body and bedstead, said bedstead mullion is a hollow structure, and corresponding bed position is equipped with bar hole on munnion, is provided with fixed pulley in each munnion upper inside wall, in munnion, be placed with counterweight, be connected with stay cord on the counterweight, stay cord is through being drawn by the bar hole on the munnion behind the fixed pulley, and links to each other with bed body frame, corresponding bed position is equipped with baffle plate in the munnion bottom, and the baffle plate bottom surface is provided with magnet.

In the lifting bed of above several different kinds of drive, all do not relate to or only relate to any safety device for the bed body, like this when the lift bed body, if the bigger article of someone or valuable volume in bed, because operator's error may cause the infringement of personnel and article, if the excesssive gap between bed body and ceiling will influence indoor whole structure, equally when the bed body descends, if bed has the people to stand below the body or when object is arranged, also can damage human body and property.

The utility model content

Technical problem to be solved in the utility model provides a kind of automatic lifting bed with safety device, can solve the potential safety hazard that a body exists in process of rising or falling.

A kind of automatic lifting bed with safety device, it comprise a body, between floor and ceiling with the equipped mutually bed body elevating mechanism of bed body, the Vidacare corp and the control device of bed body elevating mechanism, be provided with limiting plate between below below and bed body, limiting plate is provided with limit switch, and limit switch is connected with motor-driven control device.

Safety device of the present utility model is a double security device, place, corresponding bed body position is provided with the limit switch below ceiling and bed body, also be provided with the extreme position limit switch on bed body elevating mechanism, the extreme position limit switch is connected with electric controller.After preventing that the ground floor limit switch is malfunctioning, and cause danger.

Further improvement of the utility model is: limiting plate hangs and is connected below ceiling or the bed body.Limiting plate below ceiling or the bed body can also hang by spring and connect, and spring perhaps is set on suspension arrangement.

Further improvement in the technical proposal is: the limiting plate that is provided with on the bottom surface of ceiling and bed body is one, the area of limiting plate is corresponding with the bed surface of bed body, be limiting plate area greater than or be equal to the horizontal area of a body, the area of limiting plate also can be slightly less than the horizontal area of a body.

Further improvement in the technical proposal is: four groups of limit switches at least evenly are set on the limiting plate.

Owing to adopted technique scheme, the obtained technological progress of the utility model is:

The utility model is owing to be provided with limit switch on the ceiling and on the bottom surface of bed body, in the process that the bed body rises or descends, when the object on the body is run into limit switch on the ceiling or the object below the bed body and is run into the limit switch of a body bottom surface when bed body or bed, the power supply of limit switch control motor, motor is stopped operating, the bed body no longer moves, and avoids the safety of personnel and article.The extreme position limit switch plays second layer protection guaranteeing role, prevent that limit switch on the limiting plate is malfunctioning after, and cause danger.

Limit switch is connected the upper limit plate, the one, can play decoration function, make the room more neat and artistic, mainly be in order to increase the triggering area of limit switch, when there is the object that exceeds bed surface or ground a certain position on the bed or under the bed, all can runs into limiting plate, thereby touch the limit switch of a certain position, the bed body is no longer action just, makes the security of lifting bed higher.The area of limiting plate is corresponding with the bed surface size, can avoid being exposed at outside object or person wounding outside the bed, guarantees safety.Limiting plate on the ceiling connects by spring, can play certain compression to the frivolous article on the bed.
