Description

Lift-type clothes-drying rack

The utility model relates to a kind of lift-type clothes-drying rack, belongs to daily necessities.

Traditional clothes hanger that family is used for airing clothes is the metal frame that is fixedly mounted on the end face of balcony two ends, and the bamboo bar that needs during use to shine clothing by means of fork arm takes off or hangs up from fixed mount, and is very inconvenient.Though there is at present liftable clothes horse to hear generation, design unreasonablely mostly, the descending operation resistance is big, and reliability is relatively poor.

The novel purpose of this usefulness provides a kind of lift-type clothes-drying rack, and the work frictional force of making reduces, and operates lightly, uses reliable.

The utility model lift-type clothes-drying rack comprises two groups of rhombus four-link mechanisms, the a pair of mutually hinged upper boom of every group of rhombus four-bar linkage protrudes upward and is connected with a pair of chute on the fixed head separately, a pair of mutually hinged lower beam stretches out downwards and is fixed with several rings, on the lower beam jointed shaft movable pulley is housed, fixed pulley is housed on the fixed head, can stretch lifting by the while song by cable traction between two groups of four-bar linkage, said movable pulley is two coaxial pulleys that are fixed on lower beam jointed shaft two ends, the fixed pulley of a said fixed head contains two coaxial pulleys, the fixed pulley of another fixed head contains three coaxial pulleys, the rope locking mechanism should fixing also be housed, it comprises presses the rope roller, rope guarding plate and two side plates, biside plate is provided with the slotted hole of vertical direction, pressing rope roller two ends to stretch into respectively in the slotted hole of biside plate also can slide up and down in the hole, the upper end of rope guarding plate tilts to the slotted hole direction, and it makes progress decrescence with the spacing of slotted hole.A pair of chute on the fixed head is an oblique slot.Press the surperficial concave-convex surface of rope roller.The lower end of rope guarding plate is provided with the pawl type and divides prong.Be connected the riveting axle that the jointed shaft between bearing pin and each bar of rhombus four-bar linkage all adopts the end to rivet between the last rod end of rhombus four-bar linkage and the fixed head chute.

This clothes hanger is installed in the two ends of balcony end face by two fixed heads, be connected in rope between each pulley of two groups of rhombus four-link mechanisms by certain trend, work as rope for traction, when upwards promoting movable pulley, interlock takes place and makes vertical shortening of rhombus in each bar of four-bar linkage, laterally broadening, the preceding bar that dries in the air that is fixed in the ring rises thereupon; When stop pulling rope, the deadweight acting in opposition of system presses the rope roller promptly to slide to the top of slotted hole in rope, and it is locked that rope is pressed in the close gap of restricting between roller and the rope guarding plate, and four-bar linkage is in a high position and can fall.

In sum, the utility model lift-type clothes-drying rack adopts two drives, has reduced traction frictional force, and stress balance has reduced unnecessary component, thereby four-bar linkage can not produce crooked, lighter, more laborsaving during operation.

Below in conjunction with description of drawings example structure of the present utility model.

Fig. 1, Fig. 2 are the structure charts of forming two groups of rhombus four-link mechanisms of this lift-type clothes-drying rack.

Fig. 3 is the A-A profile of Fig. 1.

Fig. 4 is the B-B profile of Fig. 1.

Fig. 5 is the C-C profile of Fig. 1.

Fig. 6 is that the D of Fig. 1 is to the E of, Fig. 2 cable traction relation to view and two four-link mechanisms.

Fig. 7 is detour mode and the line alignment schematic diagram of rope between each pulley of two four-link mechanisms.

Fig. 1, Fig. 2 are two groups of rhombus four-link mechanisms forming this lift-type clothes-drying rack, the four-bar linkage of two groups of mechanisms is by two upper booms 4 and two lower beams 7 are hinged in twos forms, two movable pulleys 5,5 ' (referring to Fig. 6) is housed on the jointed shaft 14 between two lower beams 7, and the lower beam lower ends downward is stretched out and is provided with four rings 8; Two upper booms 4 protrude upward and are connected with a pair of oblique chute 3-2 of fixed head 3 by bearing pin 6 also can be along sliding in the groove, fixed head 3 has the square hole 3-1 that fixed pulley is installed, the two ends of the pulley spindle 2 of fixed pulley are semiaxis 2-1 (see figure 3), be fixed on the fixed head 3 by screw 16, be provided with two fixed pulleys 1 in the square hole of Fig. 1, be provided with in Fig. 2 square hole three fixed pulleys 1 ', Fig. 2 fixed head is equipped with the rope locking mechanism, this mechanism comprises pressure rope roller 9, rope guarding plate 10 and two side plates 11 (side plate is seen Fig. 6), side plate has the slotted hole 11-1 of vertical direction, the lower end of rope guarding plate 10 is claw type prong 10-1, can reduce the rope friction.Fig. 4 and Fig. 5 represent that rod end 4 is the riveting axle that the end rivets with the jointed shaft 14 that is connected between bearing pin 6 and two lower beams 7 of chute 3-2.In the utility model, the jointed shaft between each bar of rhombus four-bar linkage also all adopts the riveting axle.

Fig. 6 can further understand the structure of locking mechanism and the operation principle of this hoisting clothes-horse.The biside plate 11 of locking mechanism (can only see a side plate among the figure) has the slotted hole 11-1 of vertical direction, and the two ends of the pressure rope roller 9 of concave-convex surface are stretched in the slotted hole of biside plate, and rope 12 hangs downwards after striding across and pressing rope roller 9.When downward pull handle 13, movable pulley 5 and 5 ' risen by the traction of rope 12, the rhombus four-bar linkage is stressed and interlock takes place be bent upwards and rise, when stop pulling rope, the gravity that installs self make rope instantaneous oppositely move and drive press rope roller 9 to slide to the top of slotted hole 11-1, because the spacing 11-2 between slotted hole and the rope guarding plate is decrescence, so rope is pressed among the gap 11-2 that presses between rope roller 9 and the rope guarding plate 10 no longer mobilely, finished and once gone up lift operations.When needs descended clothes hanger, pull handle 13 once more, press rope roller 9 promptly to slide into the hole from slotted hole 11-1 at the bottom of, the rope release, movable pulley 5 and 5 ' fall because of deadweight, the rhombus four-bar linkage stretches downwards and descends, and finishes the step-down operation of this clothes hanger.

Fig. 7 represent rope 12 about trend between two groups of pulleys, the termination of 15 and 15 ' expression rope 12 and the end tail tieing on two fixed heads 3 respectively among the figure, rope detours in the direction of arrows from tieing 15, until tieing 15 '.
