Abstract

The utility model relates to a hydraulic rocking bed, comprising a bed head, a mattress, a bed tail and a hydraulic cylinder arranged on a bed body at the side which is adjacent to the mattress. The mattress is driven by a piston-rod which moves up and down to swing up and down, and the swing is gentle and mild, which is particularly suitable for mental workers to have a rest. Besides, the bed can be rocked with the rhyme of music, and the rocking angles and directions are changeable.

Description

Hydraulic rocking bed

The utility model relates to a kind of hydraulic pressure rocking bed, belongs to a life bed class.

In order to solve the problem that people have difficulty in going to sleep after overstrain one's nerves, physical demands is excessive.A kind of electric cradle has been announced on the Chinese utility model patent communique on May 23rd, 90, this shaking table is that motor and transmission mechanism are placed on the bed support on every side, it is big so not only to vibrate big noise, and adopt motor to promote bed board through transmission mechanism, be difficult to make the action of bed board slight, soft and reach the comfortable effect of falling asleep fast.

The purpose of this utility model is to provide a kind of action slight, soft, the hydraulic pressure rocking bed that noise vibration is minimum.

The utility model is achieved in that at the lathe bed of common bed and the adjacent surface place of mattress body a hydraulic cylinder is housed at least, the cylinder body of this hydraulic cylinder is installed on the lathe bed, the piston rod of hydraulic cylinder is installed in submarginal place, mattress body bottom, and hydraulic oil is obtained through solenoid directional control valve by oil pump.

The signal of telecommunication of solenoid directional control valve is by selector switch or by the electronic switch control that can import various audio signals.When bed shakes quietly, adopt selector switch, when bed shakes with music, control by electronic switch.

As long as if mattress body is swung, can establish a swing fulcrum at the longitudinal center section place of bed surface, adorn a hydraulic cylinder in one of the mattress body bottom of arbitrary limit of this swing fulcrum, laterally close mattress body edge, the vertically close head of a bed and tailstock.

The swing fulcrum is preferably installed a longitudinal axis that passes through among mattress body or be close to the mattress body bottom on head of a bed tailstock like this, and this longitudinal axis also can be broken into two minor axises, if camber is done in the bottom surface of mattress body also can become the swing fulcrum certainly.

If make bed surface selectively all around, shake diagonally, then can respectively adorn a hydraulic cylinder at the place, four angles of lathe bed and mattress body.

Because the utility model adopts hydraulic cylinder to make executive component, so the action that mattress body waves is very steady and soft, and noise and vibration also be minimum, and it will be optimal a kind of in the shaking table.

Be described in detail below in conjunction with embodiment:

Fig. 1 is the longitudinal sectional view of embodiment 1;

Fig. 2 is the cutaway view of Fig. 1 along the A-A line;

Fig. 3 is the transverse sectional view of embodiment 1;

Fig. 4 is the hydraulic transmission principle figure of embodiment 1;

Fig. 5 is the electrical schematic diagram of embodiment 1;

Fig. 6 is the transverse sectional view of embodiment 2;

Fig. 7 is the transverse sectional view of embodiment three;

Fig. 8 is the electrical schematic diagram of embodiment three.

Fig. 1 illustrates, and respectively has a minor axis 8 to pass through the into head of a bed 1 and tailstock 4 respectively in the both ends of the surface of mattress body 3, and piston rod 7 links to each other with mattress body 3 bottoms.Cylinder body 6 is connected with lathe bed 2, and circuit printing plate and relevant electric elements 11 are installed in the head of a bed 1, and oil pump 9 and solenoid directional control valve 10 place outside the bed.

Fig. 2 and Fig. 3 clearly show that the installation site relation between minor axis 8, the hydraulic cylinder 5.

The as can be seen from Figure 4 operation principle of hydraulic cylinder 5, it is to go out by the oil pump of oil pump 9 with oil groove, arrive the epicoele or the cavity of resorption of hydraulic cylinder 5 through solenoid directional control valve 10, drive swinging up and down of mattress body 3 thus, certainly in this oil circuit, can also add choke valve, come the action speed of regulating piston bar 7.

Fig. 5 illustrates, K switch ₂Be in music shelves I place, various audio signals are through resistance R ₁, capacitor C ₁Lotus root is closed, diode D ₄, D ₂Voltage multiplying rectifier, capacitor C ₂Filtering becomes DC voltage, then by R ₂Add to triode BG ₁Base stage, make triode BG ₁, BG ₈Conducting, DC relay J ₁Must be electric, its contact JK ₁Action, make solenoid directional control valve 11 electric, this moment, pressure oil was injected into the cavity of resorption or the epicoele of

hydraulic cylinder

5,3 of mattress bodies are rotating shaft and along with the rhythm of music swings up and down with minor axis 8.Work as K switch ₂When being allocated to noiseless shelves II place, alternating current is through directly being added to behind the bridge rectifier on the solenoid directional control valve 11, and mattress body 3 will swing up and down quietly this moment.

As can be seen from Figure 6, present embodiment two has only been done conversion with the form of the swing fulcrum of embodiment one, removes two minor axises 8 on the mattress body 3, and camber is done in the bottom of mattress body 3, and it shakes effect will be constant.

In Fig. 7, mattress body 3 is provided with fixing swing fulcrum, and removes electromagnetism latch 9, and this is the difference of it and embodiment one and embodiment two, so it has respectively adorned a hydraulic cylinder 5 at four angles of mattress body 3 and lathe bed 2, can see in conjunction with Fig. 8 and work as K ₂When placing music shelves I, by K ₁Select a kind of audio signal through R ₁C ₁Lotus root is closed, D ₁D ₂Voltage multiplying rectifier, C ₂Filtering forms DC voltage, again through resistance R ₂Add to triode BG ₁Base stage, make triode BG ₁, BG ₃Conducting, relay J ₁Contact JK ₁Action, this moment first electromagnetic switch valve events, the piston rod 7 of first hydraulic cylinder is with one jiao of jack-up of mattress body 3 or put down, because the rhythm of music is strong and weak the fluctuating, so the variation that do not stop of signal voltage, as triode BG, during conducting, signal voltage passes through resistance R ₆Add to triode BG ₂Base stage on, make triode BG ₂, BG, conducting, it is electric that second solenoid directional control valve gets, so another angle of bed also begins to go up or earthquake down, the rest may be inferred, four angles of bed are just shaken rhythmically with the variation of the strong and weak fluctuating of signal, work as K ₂Dial when putting noiseless shelves II place, the break-make of four solenoid directional control valves and order are by the selector switch AB on each solenoid directional control valve ₁, AB ₂, AB ₃, AB ₄Control.The mode of shaking of present embodiment three is convertible various, as swing, swing, to angular oscillatory motion, if carry out assembled arrangement by these several citation forms, the form of shaking will be more, its effect is with extraordinary, and it will bring more high-level enjoyment to people.
