The specific embodiment
Fig. 1 is the overall structure schematic diagram of the utility model clothes hanger lifting hand-operated device.As shown in Figure 1, the utility model provides a kind of clothes hanger lifting hand-operated device, comprises the housing 200 that is fixed on the base 100, is provided with final drive shaft 1 in the housing 200, and the axle head of final drive shaft 1 links to each other with handle 16 by rocking arm 17.Final drive shaft 1 can move back and forth in housing 200 vertically, is arranged with driving gear 2 on it.Also be provided with in the housing 200 from power transmission shaft 4, be arranged in parallel, be arranged with in turn from the power transmission shaft 4 and be used for the driven gear 5, rope sheave 6 and the rotor assembly 7 that are meshed with driving gear 2 from power transmission shaft 4 and final drive shaft 1.Describedly be separately positioned on the both sides of final drive shaft 1 from power transmission shaft 4 and sheathed thereon driven gear 5, rope sheave 6 and rotor assembly 7, and its both sides that direction is set end to end is opposite each other.Final drive shaft 1 can axially move back and forth, and sheathed driving gear 2 thereon is meshing with each other with the driven gear 5 from power transmission shaft 4,9 that is arranged on both sides respectively.Housing 200 and base 100 are provided with sleeve block 15, are provided with axle sleeve 14 in sleeve block 15, carry out spacing to moving axially of driving gear 2.Driving gear 2 is fixedlyed connected by pin 3 with final drive shaft 1, and final drive shaft 1 is contained in axle sleeve 14 and the sleeve block 15, can slide vertically.14 pairs of driving gears 2 of axle sleeve have moved axially position-limiting action, promptly move axially to when propping up axle sleeve 14 when driving gear 2, its just with driven gear 5 engagements.In addition, the external end head of final drive shaft 1 is connected with rocking arm 17, and rocking arm 17 flexibly connects by pin 18 and handle 16, and handle 16 can fold 90 ° to rocking arm 17 when not using, save the space.
Fig. 2 is the overall structure schematic diagram of driving gear, driven gear; Fig. 3 is that the A of Fig. 2 middle gear teeth is to partial enlarged drawing.As Fig. 2, shown in Figure 3, the axial section configuration of the teeth of driving gear 2 and driven gear 5 is that two ends are taper, the middle part is the spindle shape of straight line or camber line, because the radial end face of teeth is not the plane of the approximate trapezoid of general gear, but has the taper of certain wedge angle, like this when driving gear 2 moves axially to two driven gears 5 that one of them contacts, because the teeth two sides of driving gear 2 and driven gear 5 have certain wedge angle, make mutual incision engagement meeting than being easier to, can avoid two plane teeth when contact, to collide and be difficult for the problem of incision.
Fig. 4, Fig. 5 are the internal structure schematic diagram of the utility model rotor assembly.As Fig. 4, Fig. 5 and in conjunction with shown in Figure 1, rotor assembly 7 comprises rotor 71, torsion spring 8 and anticreep box 11, fixedly connected with the end face of rope sheave 6 in the outer face of rotor 71, the inner face of rotor is provided with three uniform arcs and dials pin 72, two adjacent arcs are dialled and are 120 degree angles between the pin 72, arc is dialled the inner ring that pin 72 inserts torsion spring 8, two terminations of torsion spring 8,90 degree that curve inwardly in the side that two arcs are dialled pin 72 respectively become torsion spring and dial hook 81, torsion spring 8 is placed in the anticreep box 11, torsion spring 8 is when open configuration, its outer ring closely contacts with anticreep box 11 inwalls, and anticreep box 11 is fixed on base 100 or the housing 200.
As Fig. 4, Fig. 5 and in conjunction with shown in Figure 1, driven gear 5 with fixedly connected from power transmission shaft 4, pass rope sheave 6 from power transmission shaft 4 and fixedly connected with rotor 71 usefulness pins 9.On rope sheave 6, twine the halliard of clothes hanger.Torsion spring 8 diameter when open configuration rises and closely contacts with anticreep box 11 greatly, and reduced and anticreep box 11 disengage when being applied in twisting resistance.
In conjunction with Fig. 1-shown in Figure 4, the course of work of the present utility model is such: when wanting certain clothes hanger of lifting, move final drive shaft 1 by handle 16, just aim at corresponding driven gear 5 when its side props up axle sleeve 14 when driving gear 2 moves to.Turning handle 16 then, make driving gear 2 drive driven gear 5 and rotate; The rotation of driven gear 5 drives the rotation of rotor 71; Rotor 71 is when rotating, and near the torsion spring the side that arc disposed thereon is dialled pin 72 can prop up is dialled hook 81, and when continuing to reverse handle, torsionspring 8 can tighten up and break away from anticreep box 11, and rotor 71 can drive rope sheave 6 rotations that connect firmly with it simultaneously.Forward and backward rotation by rope sheave 6 make halliard decontrol and draw in, thereby clothes hanger are risen and decline.When stopping handle 16 rotations and unclamping, thereby rotor 7 can be subjected to clothes hanger gravity effect counter-rotating that torsionspring 8 is loosened and prop up anticreep box 11, another torsion spring was dialled near rotor arc that hook 81 can prop up it and was dialled pin 72 this moment, thereby stop that rotor 71 counter-rotatings are stopped it, and the rope sheave 6 that connects firmly with it is also stopped, clothes hanger will be parked in the desired position of people this moment.
When wanting another clothes hanger of lifting, move final drive shaft 1 by handle 16, when moving to, driving gear 2 just aims at another driven gear 5 when its side props up another axle sleeve 14.From and begin above-mentioned process.
Driving gear 2 is 1: 1.5～2 with the gear ratio scope of driven gear 5, and specific to present embodiment, the number of teeth of driving gear 2 is 28 teeth, and the number of teeth of driven gear 5 is 43 teeth.Therefore it is easily laborsaving to rotate sensation than the existing sheave shaft that hand crank is directly inserted halliard when rotating hand crank.
In a word, the utility model can make more easily laborsaving, stability and safety when hoisting clothes-horse, when the different clothes hanger of lifting the hand crank conversion convenient, solved existing hand-operated device and operated painstakingly, changed inconvenient problem sometimes.
It should be noted that at last: above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that, still can make amendment and be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of the technical program, it all should be encompassed in the middle of the claim scope of the present invention.
