Abstract

The utility model relates to an electric rise-and-fall bed which is characterized in that a pillow cushion is arranged on the top of the upper half section of a bed plate, and a power switch of a lifting device is arranged on the bed body of the upper half section of the bed plate. After a motor is started, and speed is changed, pull rods are driven by a worm and worm gear speed-changing and self locking device to support the upper half section of the bed plate to rise, stop and fall. The operation is simple. The utility model does not need to be rocked by other people or self who goes down the bed to rise and fall. The pillow cushion can be used as a pillow, and the bedding can be prevented from sliding down.

Description

Motor-driven rise-and-fall bed

The utility model belongs to furniture bed technique field, is a kind of electric up-down bed.

Existing lifting bed adopts the wind that is arranged on a body afterbody to drive screw rod and rotates in hold-down nut, and screw rod drives crank as connecting rod and supporting the lifting of bed board the upper half.Because the wind of this lowering or hoisting gear is located under the body afterbody, need by other people during lifting or leave the bed handly in person, and bedding easily glide when raising, and manipulate extremely inconvenient.

The purpose of this utility model is that a kind of sleeping of design operated the electric up-down bed of lifting by me in bed.

Technical solution adopted in the utility model is improved existing lifting bed, pacify the power switch of one or two one group of normally opened contacts at the bed body of bed board the upper half one side, motor drives pull bar through the back of slowing down by worm and gear speed change self-locking device, adopts above-mentioned lowering or hoisting gear supporting bed board the upper half liter, stopping, fall; And add a bolster at the top of bed board the upper half.

Of the present utility model this electric up-down bed, only need sleep in person and press one of them normally opened contact in bed, just commentaries on classics of motor, stall, counter-rotating, bed board the upper half can rise in 0-90 ° scope, stop, descends, and it is very convenient to operate; Owing to add a bolster, can make pillow when lying, can prevent during rising that bedding such as bedding, pillow cover from gliding.

Reach example in conjunction with the accompanying drawings and further specify the electric up-down bed specific structural features of the utility model.

Accompanying drawing is represented the structural representation that the utility model is electric up-down bed.

Referring to accompanying drawing, an electric up-down bed body 1, bed board the upper half 5, bolster 6 and the lowering or hoisting gear of comprising of the utility model.Lowering or hoisting gear comprises power switch 2, motor and speed changer (not shown), driving shaft 3, worm and gear speed change self-locking device 4, pull bar 7, worm-wheel shaft 8 etc.Bed board the upper half 5 links with rotating shaft with bed body 1, bolster 6 is located at the top of bed board the upper half 5, power switch 2 is located on the bed body of bed board the upper half 5, motor and speed changer, driving shaft 3, worm and gear speed change self-locking device 4 are contained under the body, the shaft extension of motor and speed changer is connected with driving shaft 3, the worm screw of worm and gear speed change self-locking device 4 with driving shaft 3 as rotating shaft, the lower beam of pull bar 7 and worm-wheel shaft 8 vertical bindings, the upper boom of pull bar 7 and bed board the upper half 5 are connected.

For preventing electromotor overload running, the limit switch (not shown) respectively is set at two extreme positions (a bed body position that contact with bed board the upper half 5 and a body position that contacts with pull bar 7 lower beams) of bed board the upper half 5.

During lifting, sleep and stretch out one's hand a contact of pressing power switch in bed, motor just changes, by speed changer, worm and gear speed change self-locking device speed change drives the pull bar lower beam and rises 90 ° from horizontal level, decontrols the contact, the motor stall, bed board the upper half keeps the certain angle position, another contact of pressing power switch, motor counter-rotating, make bed board the upper half drop to horizontal level, decontrol the contact, the motor stall can make bed board the upper half keep the certain angle position.Two alarm contacts that extreme position is provided with up and down of bed board the upper half, but alert operator is decontroled the power switch contact, prevents electromotor overload.

Claims

1, a kind of motor lifting bed, has a body, bed board the upper half, bed board the upper half links with rotating shaft with the bed body, and lowering or hoisting gear, the top that it is characterized in that bed board the upper half is provided with bolster, lowering or hoisting gear comprises power switch, motor and speed changer, driving shaft, worm and gear speed change self-locking device, worm-wheel shaft, pull bar, power switch is located on the bed body of bed board the upper half, the shaft extension and the driving shaft of motor and speed changer are connected, the worm screw of worm and gear speed change self-locking device with driving shaft as rotating shaft, the lower beam of pull bar is vertical with worm-wheel shaft to be linked, and the upper boom of pull bar and bed board the upper half are connected, and at the two limit positions up and down of bed board the upper half limit switch is set.
