Abstract

The utility model relates to a lifting and lowering airer, which belongs to a support object for airing clothes. The utility model is composed of two sets of identical fixed plates, a diamond-shaped four rod rise and fall mechanism, pulleys, a self-lock device, etc. An object airing transverse rod is erected on the welded round ring of a connecting rod under the rise and fall mechanism. The self-lock device is arranged near a pulley on a fixed plate. Pull ropes which control two lifting and lowering frames pass through corresponding pulleys, the pull ropes pass through the middle between the rope pressing wheel and the hanging plate of the self-lock device, and then, the pull ropes are controlled by hands. The utility model has easy rise and fall and can be fixed on a position with an appropriate height according to requests. The utility model is suitable to be used under home environment.

Description

The lift airer

The utility model belongs to a kind of supporter of airing clothes.

At present, with the fixing supporter as airing clothes of bamboo bar or clothes line two ends, supporter is low excessively, occupies bigger living space usually for people, and supporter is too high, makes troubles to airing clothes again.CN2138662 discloses a kind of indoor airing frame, and this airing frame can rise and can fall, and uses more conveniently, but it can not automatically lock adjustable height according to user's wish.CN2141425 is provided with a cover self-locking mechanism on the basis of this type of lift clothes horse, but this cover mechanism structure is comparatively complicated, has also improved cost of manufacture.

The purpose of this utility model provides a kind of lift airer simple in structure, easy to use.

The lift airer that the utility model proposes, comprise two groups of identical liftable framves of forming by fixed head, rhombus four bar elevating mechanisms, pulley etc., fixed head is made into 90 ° of curved parts, be provided with two chutes above, pulley is fixed in the middle of two chutes, the termination of the last connecting rod of four-bar mechanism is installed in the chute, and lower link is provided with annulus, shines the thing cross bar and just is erected in the annulus of two groups of correspondences; It also is provided with a fixedly self-locking device of lifting position, this device is made up of vertically disposed link plate and rotating fabric wheel, fabric wheel also can move up and down in tilting groove, one end of stay cord of control crane is fixed in the pin joint of two lower links of four-bar mechanism, and the other end passes behind the fabric wheel of pulley and self-locking device and the link plate by hand control.When needs put down airing frame, stay cord is pulled to link plate one side, at this moment, fabric wheel falls in chute, and self-locking device unclamps, and the own wt of airing frame and cross bar makes four-bar mechanism flare up rhombus; When needs promote airing frame, stay cord is spurred downwards, the rhombus four-bar mechanism shrinks, the airing frame vertical-lift that makes progress when rising to needed height, is unclamped stay cord, this moment, airing frame subsided a little, stay cord drives on the fabric wheel and moves on to the top of skewed slot, thereby makes fabric wheel compress stay cord, and airing frame automatically locks.Time spent not at ordinary times, can be locked near the roof part.

Owing to adopted said structure, the utility model lifting is easy, and can be fixed on suitable height as required, is particularly suitable for using under the home environment.

Below in conjunction with embodiment the utility model is further described.

Fig. 1 is the structural representation of one-sided elevating mechanism.

Fig. 2 is the structural representation of self-locking device.

Fig. 3 is a composite diagram of the present utility model.

Referring to accompanying drawing, the utility model is by two groups of identical fixed heads 3, rhombus four bar elevating mechanisms, pulley 4 compositions such as grade, the last connecting rod 2 of four bar elevating mechanisms, 6 termination is installed in the chute 5 that is provided with on the fixed head, shine thing cross bar 14 and be erected at four bar elevating mechanism lower links 1, in the annulus 10 that welds on 7, self-locking mechanism 13 is arranged on by the pulley on the side fixed head, one end of two stay cords 8 of two cranes of control is separately fixed at corresponding four-bar mechanism lower link 1, on 7 the riveting point 9, the other end passes behind the pulley together between the fabric wheel of self-locking device 13 and link plate and passes, then by hand control.When if solarization thing cross bar 14 of the present utility model adopts light materials, thereby the possible deficiency of himself weight reach the lifting limit self so that produce friction between fabric wheel and the stay cord, at this moment can add suitable counterweight on cross bar, and mass is added on setting up a little of cross bar.The utility model is lined with rubber ring in the annulus 10 of fixed transverse rod, its effect one is the damping action that vertically moved to cross bar, and another effect is to make that cross bar and metal ring are soft to be contacted.

Claims (3)
