Abstract

The utility model provides a baby automatic cradle chair, comprising a driving device, a suspending device, and a support part. The utility model is characterized in that the driving device mainly comprises a main body frame, a rotary shaft, a ratchet gear, a clamp pin, a spring, a cranking arm, and a cranking handle, etc.; during the run of the utility model, the rotary shaft is mainly drived by the elastic force of the spring, the ratchet gear moves in one direction, the cradle suspended at the cranking arm can automatically swing, and the shortcomings of the existing cradle that the cradle is manually drived to swing. The utility model has the advantages of convenient and practical use, automatic swing, labor and time saving, and convenient dismounting.

Description

Baby automatic cradle chair

At present, children's cradle of public use is to adopt the principle of swing to make basically on the market.It relatively simple for structure generally is made up of doss, support, lifting rope etc., specializes in baby sleep and movable usefulness.Be to be kept on the cradle limit by the special messenger ceaselessly to shake during use, cradle could ceaselessly be swung.This class cradle be owing to can not shake automatically for a long time, and therefore labor intensive not only increases labour intensity, and brings certain trouble to the user.

The purpose of this utility model provides and a kind ofly saves time, laborsaving, need not electric energy, can be at the long-time baby's automatic cradle chair of swing automatically of indoor and outdoor.

The purpose of this utility model is achieved by the following scheme: baby's automatic cradle chair is made of drive unit, suspension apparatus, holder part.Its solution is: drive unit comprises main frame, rotating shaft, ratchet-gear wheel, bayonet lock, rocking arm, tension spring, string power spring, loose string rope and crank.Wherein main frame is the Jiong type, respectively has axis hole and silk hole on the vertical plane at two ends, and this axis hole is passed at the rotating shaft two ends respectively, is fixed in the two ends of main frame by latch and Jie's sheet.Be installed with tension spring chord power spring in rotating shaft respectively, wherein string power spring is fixed on the middle part of rotating shaft by screw, and tension spring is separately positioned on string power both ends of the spring.Ratchet-gear wheel props up the two ends that withstand on axle respectively by bayonet lock and tension spring, the flank of tooth and bayonet lock interlock mutually, and the light face and the rocking arm of ratchet-gear wheel are integrally welded simultaneously, and loose string rope two ends are separately fixed on the rocking arm.

The utility model also realizes by following scheme, respectively is provided with several holes in the end face of main frame and rotating shaft, and wherein two of string power spring terminations are fixed on the place, silk hole of main frame and rotating shaft respectively by screw.

Suspension apparatus described in the utility model except that installing the doss, can also be installed seat and use on the basis that does not change existing structure.

The utility model has the advantages that: convenient and practical, dismounting simply, swing automatically, save time, laborsaving.

Following structure accompanying drawing is illustrated the utility model:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the drive unit schematic perspective view.

As shown in Figure 1: this automatic cradle chair, form by drive unit, suspension apparatus, support three parts.Wherein drive unit comprises main frame 1, rotating shaft 2, ratchet-gear wheel 3(2), bayonet lock 4(2), Rocker arm 5 (2), tension spring 6(2), torque spring 7(4-6 group), loose string rope 8, crank 9, Jie's sheet 11(2), latch 10(5).Suspension apparatus comprises suspension rod 12(4), doss 13, also comprise seat.Holder part is made up of four legs 14, front and back cross bar 15 and collapsible pole 16.

Embodiment is: main frame 1 is made the n type, and several little silk holes supply fixedly torque spring 7 usefulness on its end face bores.Axis hole of the Ge Kai up and down of main frame two ends vertical plane and two silk holes, the silk hole is used for fixing leg 14 usefulness.Rotating shaft 2 is passed from the axis hole of main frame, has drilled through some apertures in the rotating shaft, uses for latch and bayonet lock.The rotating shaft two ends are fixed on the main frame by Jie's sheet and latch 10.But rotating shaft is free to rotate.Rotating shaft one end top is square, and matches with crank 9 center square holes, after putting, can shake.The both sides symmetry is respectively assigned a bayonet lock 4 in the rotating shaft, with relative ratchet-gear wheel (being through in the rotating shaft) phase interlock, makes in the rotating shaft and can rotate by a direction.Two rocking arms have been welded at the ratchet-gear wheel back side (the no flank of tooth), and like this, rocking arm is swung simultaneously with rotating shaft.The back side of being close to rocking arm is by being equipped with two groups of compression springs (being through in the rotating shaft), the other end of compression spring be fixed by a latch 10 and Jie's sheet 11 respectively and make it and withstand on rocking arm and Jie's sheet between, impel coincideing of 4 of ratchet-gear wheel and bayonet locks, torque spring 7 is installed in the middle part of rotating shaft, one end of spring is fixed on the rotating shaft silk hole by screw, the other end is fixed on the main frame by screw, and rocking-turn crank, torque spring rotate with rotating shaft and tighten up.A hole is respectively established in the rocking arm lower end, supplies fixedly Song Lisuo 8 usefulness.

When the needs torque spring is lax, during reinstatement, need only press Song Lisuo, allow ratchet-gear wheel and bayonet lock separate, rotating shaft i.e. counter-rotating voluntarily, and spring restores, and leg 14 is fixed on below, main frame two ends in two combined moving type modes.The leg below is by fixedly pole 15 and folding type movable pole interconnect.Up press movable branching rod 16, leg can close extension.The rocking arm lower end has four holes, uses for fixed derrick 12.Doss is equipped with hook for 13 4 jiaos, so that suspension rod can tangle doss.Suspension rod also can change the extension seat.
