Abstract

The utility model discloses a counterweight-type electric assisting hoisting bed, comprising a bracket, an electric motor and a bed body. The bracket is fixed on the wall body by a fixed bolt; the bed body is fixed on the slideway of the bracket by a pulley; the bed body is connected with the electric motor by an electric motor towing belt. The utility model is characterized in that the counterweight-type electric assisting hoisting bed also comprises a counterweight body which is connected with the bed body by a counterweight towing belt after passing through the fixed pulley fixed on the upper part of the bracket. The top part of the bracket is provided with a cantilever beam on which the fixed trolley is fixed; the electric motor is arranged in a tank body arranged on the lower end of the bracket; the tank body, the cantilever beam and the bracket are integrated to a whole, so as to form a transverse U-shaped structure. The hoisting bed adopts the overload counterweight way, so that the counterweight body moment is larger than the moment generated by the bed body, and the moments are opposite, thus realizing the aim that the bed body only has the uplifting ability without the external force, and resolving the hidden trouble of unexpected falling of the bed body. In addition, the utility model has simple structure and low cost, which is suitable for being popularized in the family life.

Description

The electronic assistance for lifting bed of counter weight type

Technical field

The utility model relates to a kind of electric up-down bed, relates in particular to the electronic assistance for lifting bed of a kind of counter weight type.

Background technology

In order to increase floor space, the someone has invented a kind of electric up-down bedly, can be raised to ceiling or roof when not using so that save the space, can drop in bed and use height.But there is following problem in existing lifting bed:

1, there are many potential safety hazards and use inconvenience, have a body to fall unusually often and the accident of bed body abnormal motion takes place.

2, lose its lifting and positioning function in outage and the motor abnormal conditions body of leaving the bed.

3, its motor of bed body of inventing in the past and designed is in loaded state all the time, and reduced its service life greatly.

Summary of the invention

The utility model draws and develop a kind of employing balance weight body at the proposition of above problem, the electronic assistance for lifting bed of the counter weight type of electronic motor-driven assistance for lifting.The technological means that the utility model adopts is as follows:

The electronic assistance for lifting bed of a kind of counter weight type, comprise: support, motor and bed body, described support is fixed on the body of wall by set bolt, described bed body is fixed on the slideway of support by pulley, a body is slided up and down along the slideway of support, in addition, the bed body is connected on the motor by the motor traction belt; It is characterized in that also comprising balance weight body, described balance weight body is connected on the body after by the fixed pulley of counterweight traction belt through being fixed on support top.

The top of described support is provided with overarm, fixed thereon of fixed pulley; Described motor is arranged in the casing of support lower end; Described casing, overarm for being wholely set, have constituted " U " type structure of a traverse with support.

Be provided with stiff end on bed body top, and on the relative position on support top, be provided with and insure, after the bed body rises to the top, go up stiff end with the locking mutually of insuring.

Be provided with stiff end down in bed body bottom, and insurance down be set, stiff end insurance locking mutually down together down after the bed body drops to the bottom desired location at the relative position of described casing.

Described motor is the rolling screen door motor, is made up of motor, clutch, bottle gouard moved by hands, electromagnet brake and travel switch.Connect with the bed body by running block in described balance weight body.

Because electronic its advantage of assistance for lifting bed of counter weight type that has adopted technique scheme, the utility model to provide is conspicuous, and is specific as follows:

1, falls unusually and abnormal motion at the bed body, thereby invention taked its balance weight body moment of overload counter weight type method greater than bed body institute's moment that produces itself and the opposite body of having realized of the two moment at the potential energy that is not subjected to have only under the external force situation rising, thereby solved the accidental falling hidden danger of a body.

2, lose its function situation at the bed body in the outage situation, the method that the present invention adopts bottle gouard moved by hands and clutch electromechanics magnetic brake device to combine has realized the leave the bed continuity of body lifting and positioning function of powering-off state

3, the bed body is placed at 2 and adopted semi-automatic self-locking safety device in the use location, makes it before arming, and is unloaded fully when avoiding any abnormal displacements of a body and using motor to be in two positions.Thereby improved the security of device, prolonged the service life of motor.

Because it is simple in structure, not only be convenient to produce, and the extensively popularization placed in the middle that is suitable for being in low cost.
