A kind of movable baseTechnical field
The invention belongs to household electrical appliance technical field of auxiliary equipment, more particularly to a kind of movable base.
Background technology
White goods equipment, air-conditioning, washing machine, sofa that existing white goods equipment includes etc., is all slided without Tape movementWheel, when causing the carrying of white goods equipment and be mobile, needs entirety to lift equipment, because weight needs many people to be grasped together againMake, waste time and energy, operation is also inconvenient.
The content of the invention
The purpose of the present invention, which is that, to be overcome the deficiencies in the prior art there is provided a kind of movable base, bottom of the inventionSeat is used for integral installation in the bottom of existing white goods equipment, facilitates the movement and carrying of white goods equipment, greatly improvesThe features of white goods equipment, the life given people brings great convenience.
To achieve these goals, the invention provides a kind of movable base, including pedestal, motor, screw mandrel, screw rod bushingAnd pulley；The motor is installed on the top of the base vivo wall, and the motor is connected with the top of the screw mandrel；The silkThe top of rod set is provided with internal thread hole, and the bottom of the screw rod bushing is provided with open slot, and the wire rod thread is connected to describedIn the internal thread hole of screw rod bushing, the pulley is rotatablely installed at the open slot of the screw rod bushing bottom by bearing pin, the seatThe bottom of body is provided with circular hole relative to the pulley position；The both sides that the pedestal is located at the circular hole are relatively set with short arcGroove and long arc groove, the right-hand member of the long arc groove are provided with electromagnet, and electromagnet is connected by spring with nahlock.
Beneficial effects of the present invention：The present invention base integral installation in the bottom of white goods equipment, during installation according toThe base of the different numbers of demand installation is placed in the bottom of white goods equipment, is ensureing the movement of white goods equipment and convenient in carryingWhile, do not influence the normal of white goods equipment to use；When white goods equipment is moved, electromagnet obtains electric, and electromagnet is inhaledDraw nahlock to be reduced in long arc groove, spring is compressed, and circular hole is opened, now motor rotate forward drive screw mandrel rotate, screw mandrel rotate withScrew rod bushing is driven to be moved down along screw mandrel, screw rod bushing is moved down to be worn to drive the pulley of screw rod bushing bottom to move down from the circular hole of pedestalMotor stop motion after out, now pulley contact ground, pulley realizes the movement and carrying of white goods equipment.When withoutDuring mobile or carrying large home appliance, motor reversal, screw mandrel is rotated to drive screw rod bushing to be moved up along screw mandrel, and screw rod bushing is moved upMotor stop motion after being risen to the pulley for driving screw rod bushing bottom in pulley retraction pedestal, now the bottom surface of pedestal is contiguouslyFace, white goods equipment is smoothly supported on the ground, is normally used；While electromagnet dead electricity, nahlock is made in the elastic force of springUnder, moved from long arc groove to short arc groove and cover circular hole completely, prevent dust and other impurities from entering from circular hole in pedestal and pollutingPart in pedestal.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existingThere is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only thisSome embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be withOther accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the base of the embodiment of the present invention.
Embodiment
Invention is further illustrated below in conjunction with the accompanying drawings, but is not limited to the scope of the present invention.
Embodiment
As shown in figure 1, a kind of movable base that the present invention is provided, including pedestal 51, motor 52, screw mandrel 53, screw rod bushing54 and pulley 55；The motor 52 is installed on the top of the inwall of pedestal 51, the top of the motor 52 and the screw mandrel 53It is connected；The top of the screw rod bushing 54 is provided with internal thread hole, and the bottom of the screw rod bushing 54 is provided with open slot, the silkBar 53 is threadedly connected in the internal thread hole of the screw rod bushing 54, and the pulley 55 is rotatablely installed in the screw mandrel by bearing pin 56At the open slot for covering 54 bottoms, the bottom of the pedestal 51 is provided with circular hole 58 relative to the position of pulley 55；The pedestal51 both sides for being located at the circular hole 58 are relatively set with short arc groove and long arc groove, and the right-hand member of the long arc groove is provided with electromagnet57, electromagnet 57 is connected by spring 60 with nahlock 59.
The base integral installation of the present invention installs different numbers according to demand in the bottom of white goods equipment during installationBase is placed in the bottom of white goods equipment, while the movement of white goods equipment and convenient in carrying is ensured, does not influence large-scaleThe normal of home appliance is used；When white goods equipment is moved, electromagnet 57 obtains electric, and electromagnet 57 attracts nahlock 59 to be reduced to lengthIn arc groove, spring 60 is compressed, and circular hole 58 is opened, and now motor 52, which is rotated forward, drives screw mandrel 53 to rotate, and screw mandrel 53 is rotated with bandDynamic screw rod bushing 54 is moved down along screw mandrel 53, and screw rod bushing 54 is moved down to drive the pulley 55 of the bottom of screw rod bushing 54 to move down from pedestal 51Circular hole 58 in wear out the rear stop motion of motor 52, the now contact of pulley 55 ground, pulley 55 realizes white goods equipmentMovement and carrying.When without mobile or carrying large home appliance, motor 52 is inverted, and screw mandrel 53 rotates to drive screw rod bushing54 move up along screw mandrel 53, and screw rod bushing 54 moves up to drive the pulley 55 of the bottom of screw rod bushing 54 to rise to the retraction pedestal 51 of pulley 55The bottom surface contact ground of the interior stop motion of rear motor 52, now pedestal 51, white goods equipment is smoothly supported on the ground, justOften use；Simultaneously the dead electricity of electromagnet 57, nahlock 59 spring 60 elastic force effect under, from long arc groove to short arc groove move and it is completeCircular hole 58 is covered, prevents dust and other impurities from entering from circular hole 58 in pedestal 51 and polluting the part in pedestal 51.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industryPersonnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originallyThe principle of invention, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these changesChange and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and itsEquivalent is defined.
