The device has the advantages of sanitation and convenience.
Description
Technical field
The present invention relates to a kind of mechanical flow adjusting device.
Background technique
In some special occasions, such as infectious hospital, laboratory etc., a lot of people carry disease, if at this moment can be very unhygienic with hand, use instead foot-operated can be better.And device in the past is exactly that a permanent opening is set, the majority spring reset.Such drawback has: be at first that flow is uncontrollable, the people is as long as flow arrives maximum once stepping at once, and still, nowadays water resources is so valuable, and having does not many times need so large flow to wash in fact.Next is, if use spring reset, mean the people if the words of water want pin stepping on pedal always, but not all people is the short time water, need to fill one large water such as the cleaning personnel of hospital when the water receiving, and they are when the work of washing mop and so on, if pin of people also will stepped on pedal, must cause people's balance bad, not only can't work but also easily trample on pedal.It is controlled that this device can satisfy flow, and the people need not stepping on for a long time pedal.
And using water wisely to also have an important aspect be exactly the pass water of people after using, as the water tap with the hand adjustment joint, the somebody can be dirty etc. former thereby be not related to valve because being afraid of, and this device switch hygienic and convenient very all.
Summary of the invention
In order to overcome the unhygienic with hand of existing flow regulator, and pin need stepped on the deficiency of pedal always when using, the invention provides a kind of novel mechanical flow adjusting device, this device not only can be realized need not with hand only with riding water, and can allow the people by riding switch tap and adjust flux easily, need not the advantage that pin is being stepped on pedal always when possessing simultaneously use.
Mechanical flow adjusting device of the present invention comprises the spherical valve that is arranged on water pipe, it is characterized in that: described spherical valve is connected in the rotating shaft of rotating disk, and described rotating disk is driven by a brace and connecting rod framework; The connecting rod of described connecting rod is connected in a sliding sleeve, and described sliding sleeve is located on the right-hand tread plate connecting rod, and the end of described right-hand tread plate connecting rod connects right-hand tread plate, and the other end of described right-hand tread plate has two position limit pins that limit the sliding sleeve position; Described right-hand tread plate connecting rod and left-hand tread plate rod hinge connection, the end of described left-hand tread plate connecting rod connects left-hand tread plate; Another end connecting rope of described left-hand tread plate connecting rod, described rope are walked around on the limit stick of the described connecting rod of static pulley connection.
This product solving the scheme that its technical problem adopts is, allows a spherical valve first is installed in water pipe, and the above connects a slightly large rotating disk, adopts the screw rod connection of self-locking thread between them.Connect rotating disk with connecting rod.Two pedals connect respectively connecting rod indirectly.The connecting rod that the left-hand tread plate of control pass minor valve connects connects the rope by static pulley, and the other end of rope is connected on a stub, and this rod is welded on the connecting rod of vertical motion.This connecting rod is enclosed within a pair of retaining ring.Connect by slidercrank mechanism and control the right-hand tread plate of opening large valve.To be provided with two position limit pins on the bar of slide-block mechanism fixed establishing, and both can limit the stroke of slide block, can guarantee simultaneously again the angle of valve rotating disk.The most important thing is not allow that point of contact that connects rotating disk arrive peak or minimum point, because if point of contact just arrives peak or minimum point and stops, at this moment be equivalent at the dead point subsequent can't moving, namely enable motion, can't guarantee that also it is toward still motion counterclockwise clockwise.And for spherical valve, when arriving of flow is maximum, then changeover valve is also nonsensical.Above-described structure can guarantee that two pedals just in time are in opposite position, starting stage, open the right-hand tread plate of large valve upper, the left-hand tread plate that closes minor valve under, at this moment if step on out the right-hand tread plate of large valve, vertically connecting rod moves upward, the rope tension, the left-hand tread plate that closes minor valve will perk, and then user's left-hand tread plate of stepping on perk just can turn down the valve regulated flow, the direct throttle down of perhaps can disposablely flooring.Original state is got back in the position of two pedals.Simultaneously, indicate the sign of " opening " and " pass " on two pedals, be convenient to people's identification.So just can reach flow adjustable, need not long stepping on, switch is purpose easily.
The invention has the beneficial effects as follows, clean hygiene need not to touch with hand, and having can adjust flux, need not step on the advantage of pedal during use always; Be convenient to the user and use, can allow its using water wisely simultaneously.

Embodiment
With reference to accompanying drawing:
Mechanical flow adjusting device of the present invention comprises the spherical valve 17 that is arranged on water pipe 16, and described spherical valve 17 is connected in the rotating shaft of rotating disk 14, and described rotating disk 14 is driven by a brace and connecting rod framework; The connecting rod 13 of described connecting rod is connected in a sliding sleeve 10, described sliding sleeve 10 is located on right-hand tread plate connecting rod 6, the end of described right-hand tread plate connecting rod 6 connects right-hand tread plate 5, and the other end of described right-hand tread plate 5 has two position limit pins that limit sliding sleeve 10 positions: left limit pin 1 and right limit pin 9; Described right-hand tread plate connecting rod 6 is hinged with left-hand tread plate connecting rod 3, and the end of described left-hand tread plate connecting rod 3 connects left-hand tread plate 4; Another end connecting rope 8 of described left-hand tread plate connecting rod 3, described rope 8 are walked around static pulley 7 and are connected on the limit stick 12 of described connecting rod 3.
Described connecting rod is made of with small rod 15 connecting rod 13 that is hinged.
In Fig. 1, be original state, valve closing, people's pin is stepped on right-hand tread plate 5, and left-hand tread plate connecting rod 3 and right-hand tread plate connecting rod 6 rotate around its hinged dead axle 2, make connecting rod 13 upwards, promote small rod 15 motions, thereby drive rotating disk 14 motions, have opened spherical valve 17.
And when connecting rod 13 moves upward, rope 8 right-hand member tensions, rope is walked around static pulley 7, and the rope left end pulls left-hand tread plate connecting rod 3, makes its right-hand member downward, and left-hand tread plate 4 is upturned.When right-hand tread plate 5 was floored, sliding sleeve 10 was encountered position limit pin 9, and it is maximum that flow reaches.This moment as shown in Figure 2.
Then, then step on left-hand tread plate 4, rope 8 connecting rod 13 of leaving behind, thus small rod 15 rotates rotating disk 14, has turned down spherical valve 17.In this simultaneously, left-hand tread plate connecting rod 3 right-hand members are downward, right-hand tread plate 5 perks.When sliding sleeve 10 was encountered position limit pin 9 again, water tap was closed.Get back to state shown in Figure 1.
The described content of this specification embodiment is only enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also reaches conceives the equivalent technologies means that can expect according to the present invention in those skilled in the art.
