Abstract

The utility model relates to a movable electric lift bed comprising a bed frame and fixed bed board arranged thereon. One end of the fixed bed board is articulated in sequence with a rear connection bed board and a rear bed board while the other end thereof with a front connection bed board and a headrest board; a front motor and a rear motor are respectively arranged under the bed frame and the shaft of each motor is of a worm and is matched correspondingly with rotary screw rods with a worm wheel at the head; each rotary screw rod is correspondingly matched through screws with a moving block, the end part of which is contacted with the end part of a bending rod, each of which is articulated on the bed frame; one end of a rear connection rod is relatively fixed in the same rod with the corresponding bending rod and the other end thereof is articulated with the front part and the rear part of the bed board to form a front part bed board lift mechanism and a rear part bed board lift mechanism. The utility model has reliable structure, silent operation, low power consumption in motor, high security and no pollution.

Description

The electric up-down pulldown bed

Technical field: the utility model relates to a kind of bed of liftable activity.

Background technology: many people like lying and read a book, see TV etc. on the bed, and the bed of general closed planar also is not suitable for, and makes people's posture unreasonable, is easy to fatigue.The lifting pulldown bed is arranged now, can make the lifting of bed board each several part, be fit to the needs of people's comings and goings, but general lifting activity actuation mechanism all adopts hydraulic mechanism, noise is all bigger with power consumption during operation, complex structure, and security is not high enough, and leakage of oil influences environment easily.

Summary of the invention: the utility model is to solve the deficiency that prior art adopts hydraulic mechanism, provides a kind of simple in structure, reliable, the electric up-down pulldown bed that operation is quiet, safe.Fixed bed board on the utility model comprises a pedestal and is connected it, before the fixed bed board two ends are hinged with respectively, connect bed board with after be connected bed board, this back connects bed board and the back bed board is hinged, after-poppet is located on the bed board of back, have rear motor at the bed pedestal, the axle of this rear motor is a worm screw, itself and head are that the rotary screw of worm gear cooperates, movable block and rotary screw threaded engagement, knee one end is hinged on the pedestal, the other end contacts with the movable block end, and back link one end is hinged on the after-poppet, and the coaxial relative fixed of the hinged end of the other end and knee constitutes rear portion bed board elevating mechanism; The preceding adjacent head splint that is provided with of bed board that connects, hinged preceding bed board that connects of fore-stock, the other end is connected with head splint, on the bed pedestal, also be provided with front motor, rotary screw, movable block, knee and the front rod identical with rear portion bed board elevating mechanism, the preceding hinged fore-stock of elevating lever one end, the hinged front rod of the other end constitutes anterior bed board elevating mechanism.

Utilize motor, rotary screw, movable block and knee etc. to form elevating mechanism, simple and reliable for structure, peace and quiet during operation, the required motor power consumption is very little, and is safe, do not pollute.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: accompanying drawing is the structural representation of embodiment.

Embodiment: as shown in the figure, fixed bed board 20 is located on the pedestal 1, connect before fixed bed board 20 two ends are hinged with respectively bed board 10 with after be connected bed board 2, this back connects bed board 2 and back bed board 3 is hinged, after-poppet 4 is located on the bed board 3 of back, have rear motor 5 at bed pedestal 1, the axle of this rear motor 5 is a worm screw, itself and head are that the rotary screw 6 of worm gear cooperates, movable block 7 and rotary screw 6 threaded engagement, knee 8 one ends are hinged on the pedestal 1, and the other end contacts with movable block 7 ends, back link 9 one ends are hinged on the after-poppet 4, and the coaxial relative fixed of the hinged end of the other end and knee 8 constitutes rear portion bed board elevating mechanism; The preceding bed board 10 adjacent head splints 11 that are provided with that connect, 12 1 hinged preceding bed boards 10 that connect of fore-stock, the other end is connected with head splint 11, on bed pedestal 1, also be provided with front motor 13, rotary screw 14, movable block 15, knee 16 and the front rod 17 identical with rear portion bed board elevating mechanism, the preceding hinged fore-stock 12 of elevating lever 18 1 ends, the hinged front rod 17 of the other end constitutes anterior bed board elevating mechanism.Can spread mattress 19 on bed board, be generally soft mattress, present embodiment is provided with the electric massage mattress, can also carry out therapeutic massage like this.

When wanting lifting,, can start rear motor 5 as rising back bed board 3, cooperate rotation rotary screw 6 by worm and wormwheel, movable block 7 is moved, and the end of knee 8 is pushed around hinged center and rotates, and back link 9 is simultaneously by coaxial rotation and lifting after-poppet 4 and back bed board 3.When wanting lifting preceding connection bed board 10 and head splint 11, then start front motor 13, same action.Present embodiment also can be set level on bed pedestal 1 fully, adapts to various situations.
