Abstract

The utility model relates to an automatic alarm giving transfusion frame, which is composed of a bottom frame, a vertical rod, a crosspiece and a hanging rod, wherein a power supply, a horn, a switch and a microswitch are arranged in the crosspiece; the middle part of the hanging rod is fixed to the crosspiece through a shaft; a screw rod and a spring penetrate through one end of a vertical hole of the crosspiece, and the one end is connected with the hanging rod; a contact point of the microswitch is opposite to the other side of the hanging rod; the switch, the microswitch, the horn and the power supply are connected through conductive wires. The utility model has the advantage that by the lever principle, an alarm circuit is artfully controlled by weight during transfusion through lever action, therefore the utility model has simple structure, small stress on the spring and the microswitch, damage difficulty, adjustment at any time according to transfusion quantity and the weight of a transfusion bottle, and convenient and flexible adjustment.

Description

Automatic warning drip stand

Technical field

This utility model relates to a kind of transfusion adnexa, particularly a kind of automatic warning drip stand.

Background technology

Existing warning drip stand is the purpose that reaches warning, often adopt the structure of more complicated, as the Chinese patent 95204146.4 disclosed suspension type guide rail cableways automatic warning drip stand that slides, it is by suspension rod, suspension hook, the infusion bottle suspension hook, pulley yoke, the metering extension spring, microswitch, display lamp, guide rail, rope assembles, suspension hook is connected on the suspension rod upper end, be hooked in the circular hole of pulley yoke bottom, pulley yoke is directly held adapter sleeve lifting handle on suspension rod by the infusion bottle suspension hook, the other end hooks infusion bottle, metering extension spring one end is hooked in infusion bottle suspension hook middle part, and the other end is hooked in extension spring levelling frame upper end.Gravity by infusion bottle is used for controlling microswitch to extension spring, thereby the control display lamp reminds transfusion to finish.In addition, adopt extension spring to control, touch switch, because extension spring frequently stretches, can influence its elasticity, until following the string, so also there is short, the not high shortcoming of sensitivity in service life in it.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and automatic warning drip stand is provided, and makes that it is simple in structure, regulate sensitive, long service life.

This utility model solves the problems of the technologies described above the technical scheme that is adopted:

Automatic warning drip stand, be made up of underframe, montant, crosspiece and peg, power supply, loudspeaker, switch, microswitch are housed in the crosspiece, the peg middle part is fixed on the crosspiece by axle, screw rod and spring pass the end that the crosspiece vertical core is connected peg, and the front contact of microswitch is facing to the opposite side of peg; Switch, microswitch, loudspeaker and power supply are connected by lead.

Compared with prior art, advantage of the present utility model is: according to lever principle, weight when utilizing transfusion is controlled warning circuit cleverly by leverage, therefore it is simple in structure, spring and microswitch stressed little, not fragile, and can be according to the weight of amount of infusion and infusion bottle and adjust at any time, regulate flexible.

Description of drawings

Fig. 1 is the structural representation of this utility model embodiment;

Fig. 2 is the circuit diagram of this utility model embodiment.

The specific embodiment

Embodiment describes in further detail this utility model below in conjunction with accompanying drawing.

As shown in Figure 1, automatic warning drip stand, it is made up of underframe 13, montant 11, crosspiece 3 and peg 8, battery 2, loudspeaker 4, switch 5, microswitch 6 are housed in the crosspiece 3, peg 8 middle parts are fixed on the crosspiece 3 by axle 9, become lever, screw rod 1 and spring 10 pass an end that is connected peg 8 in crosspiece 3 vertical cores, and the front contact of microswitch is facing to the opposite side of peg.

Whole warning circuit is seen Fig. 2, connects microswitch 6, loudspeaker 4 and power supply 2 by switch 5 and forms, and when closing a switch 5 the time, touches microswitch 6 again and just connects whole warning circuit, and loudspeaker 4 are just sounded.Loudspeaker also can be the equipment of playing melody.

During normal infusion, colluding of peg 87 hangs up infusion bottle 12, closes a switch 5, and the weight of infusion bottle 12 and liquid is heavier, and peg 8 just overcomes the effect of spring force and leaves microswitch 6, so warning circuit is not opened.When the liquid in the infusion bottle is totally lost, an end of spring 10 compressing pegs 8 and with infusion bottle 12 these ends toward upwarping and the microswitch 6 of closing, connect warning circuit, loudspeaker 4 just send chimes of doom, remind liquid to be totally lost.

Because what of the size of infusion bottle and amount of infusion can change the stressed of peg 8 these ends, therefore need adjust the stressed of the other end by screw rod 1.Screw screw rod 1, can holddown spring 10, thereby increase the elastic force of 10 pairs of pegs 8 of spring, otherwise, unscrew screw rod 1, then pull-off spring 10, thereby reduce the elastic force of 10 pairs of pegs 8 of spring, adapt to what of the size of infusion bottle and amount of infusion by such adjusting, make warning circuit all can play effect.

6 designs of above-mentioned microswitch are only exposed its front contact in crosspiece 3, can not run into whole microswitch 6 during peg 8 bumps like this, and run into crosspiece 3 and stop, and therefore can not damage microswitch because of peg 8 often clashes into microswitch.

Spring 10 other ends are enclosed within on the projection 14 of peg 8, easier like this qualification spring 10.

Underframe also is other forms, and as board-like, bar also can be telescopic.

Claims

1, the drip stand of reporting to the police automatically, form by underframe, montant, crosspiece, it is characterized in that: power supply, loudspeaker, switch, microswitch are housed on described crosspiece, under described crosspiece, peg is set, the peg middle part is fixed on the crosspiece by axle, screw rod and spring pass the end that the crosspiece vertical core is connected peg, and the front contact of microswitch is facing to the opposite side of peg; Switch, microswitch, loudspeaker and power supply are connected by lead.

2, automatic warning drip stand as claimed in claim 1, it is characterized in that: described microswitch is only exposed its front contact in crosspiece.
