Description

The mechanical flow controlling device

Technical field

The utility model relates to a kind of mechanical flow controlling device.

Background technique

In some special occasions, such as infectious hospital, laboratory etc., much human is all carried 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, and majority is used spring reset.Such drawback has: at first be that flow can not be controlled, 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 big flow to wash in fact.Next is if use spring reset, then to mean the people if the words of water want pin stepping on pedal always; But not all people is the short time water, need fill one big 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 trample on pedal easily.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 have nothing to do with valve because of being afraid of, and this device switch hygienic and convenient very all.

Summary of the invention

In order to overcome the unhygienic of existing flow regulator with hand; And pin need stepped on the deficiency of pedal always when using; The utility model provides a kind of new mechanical formula flow regulator; This device not only can be realized need not with hand only with riding water, and can let the people through riding easily the switch tap and regulating flow, possesses when use simultaneously to need not the advantage that pin is being stepped on pedal always.

The described mechanical flow controlling device of the utility model comprises the spherical valve that is arranged on the 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; The terminal connecting rope of another of described left-hand tread plate connecting rod, described rope are walked around on the limit stick that static pulley connects described connecting rod.

This product solving the scheme that its technical problem adopted is, lets a spherical valve is installed earlier in water pipe, connects a big slightly rotating disk above, adopts the screw rod of self-locking thread to connect between them.Connect rotating disk with connecting rod.Two pedals connect connecting rod respectively indirectly.The connecting rod that left-hand tread plate connected that minor valve is closed in control connects the rope through static pulley, and the other end of rope is connected on the stub, and this rod is welded on the connecting rod of vertical motion.This connecting rod is enclosed within a pair of retaining ring.And control is opened the right-hand tread plate of big valve through the slidercrank mechanism connection.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 the angle of valve rotating disk again simultaneously.The most important thing is not allow that point of contact that connects rotating disk to arrive peak or minimum point; If, at this moment be equivalent at the dead point subsequent can't moving because point of contact just arrives peak or minimum point and stops; Promptly enable motion, can't guarantee that also it is toward still motion counterclockwise clockwise.And for spherical valve, when arriving of flow was maximum, changeover valve was also nonsensical again.Above-described structure can guarantee that two pedals just in time are in opposite position, and the starting stage, the right-hand tread plate of opening big valve is last; The left-hand tread plate that closes minor valve is down, at this moment if step on out the right-hand tread plate of big valve, vertically connecting rod moves upward; Rope is drawn; The left-hand tread plate that closes minor valve will perk, and 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 then.Original state is got back in the position of two pedals.Simultaneously, on two pedals, indicate the sign of " opening " and " pass ", be convenient to people's identification.It is adjustable so just to reach flow, need not long stepping on, and switch is purpose easily.

The beneficial effect of the utility model is that clean hygiene need not to bump with hand, has and can regulate flow, need not step on the advantage of pedal during use always; Person easy to use uses, and can let its using water wisely simultaneously.

Embodiment

With reference to accompanying drawing:

The described mechanical flow controlling device of the utility model comprises the spherical valve 17 that is arranged on the 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 the 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; The terminal connecting rope 8 of another 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 up of connecting rod that is hinged 13 and small rod 15.

Among 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 rotates around its hinged dead axle 2 with right-hand tread plate connecting rod 6, makes connecting rod 13 upwards, promotes small rod 15 motions, thereby drives rotating disk 14 motions, has opened spherical valve 17.

And when connecting rod 13 moved upward, rope 8 right-hand members were drawn, and rope is walked around static pulley 7, and rope left end pulling 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 run into position limit pin 9, and it is maximum that flow reaches.This moment is as shown in Figure 2.

Then, step on left-hand tread plate 4 again, 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 run into position limit pin 9 once more, water tap was closed.Get back to state shown in Figure 1.

The described content of this specification embodiment only is enumerating the way of realization of model utility design; Should not being regarded as of the protection domain of the utility model only limits to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
