Abstract

The utility model relates to a water fountain safety faucet composed of a valve body, a valve cover fixed on the top of the valve body, a piston matched with a valve seat inside the valve body, a valve rod penetrated through a through hole on the valve cover and a reset spring inflicting a deflective pressure on the piston. One side of the valve rod is fixed with the piston and the other side is hinged with a main handle. An auxiliary handle revolving in relation to the main handle is arranged between the main handle and the valve cover. When the auxiliary handle is switched at a first position, at least a portion of the auxiliary handle is positioned under the main handle to retard the action of the main handle; when the auxiliary handle is switched at a second position, a gap formed on the auxiliary handle is aligned with the main handle to allow that the main handle is operated. The safety performance of the water fountain can be enhanced by only adding a few parts on the faucet of a prior water fountain.

Description

Drinking machine is leading with safety

Technical field:

It is leading with safety that the utility model relates to a kind of drinking machine.

Background technique:

On the existing drinking machine, two depotition cocks are installed usually, a hot water tap and a cold water faucet, during use, only need press an end of main handle, by the cam mechanism on the main handle, main handle is produced to rotatablely move, by valve rod, promote the piston in the water tap, emit hot water or cold water.Though its operation is simple, there is potential scald children's hidden danger.

The model utility content:

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, a safety installations is set at existing drinking machine on tap, its main handle rotation relatively, main handle is locked in leading closed position, perhaps discharges main handle, but make tap be in opening state.

Leading according to drinking machine of the present utility model with safety, comprise a valve body, it has an intake tunnel that is communicated with the drinking machine heating container, one exhalant canal and one is communicated with the inner chamber of intake tunnel and exhalant canal, described inner chamber is formed with a valve seat that can match with a piston with the connecting part of exhalant canal, one valve gap is fixed on described valve body top, one valve rod passes the through hole on the described valve gap, one end and the piston of valve rod are fixed together, the other end of valve rod and a main handle are hinged, an and Returnning spring that described piston is applied bias voltage, it is characterized in that, between described main handle and the described valve gap, be provided with an assist handle that can rotate relative to main handle, when described assist handle rotates to primary importance, at least a portion of assist handle is positioned at the main handle below, stop the main handle action, rotate to the second place and work as described assist handle, the breach and the main handle that are formed on the assist handle align, and allow the operation main handle.

The utility model only needs just main handle to be locked in the position that tap is closed at the safety installations of existing drinking machine with a small amount of part formation of increase on the tap, perhaps discharges main handle, but makes tap be in opening state.Its operation is very simple, has greatly improved the Safety performance of drinking machine.

Description of drawings:

Fig. 1 is a perspective exploded view, schematically illustrates according to a kind of embodiment of drinking machine of the present utility model with the safety tap;

Fig. 2 is a signal erection drawing embodiment illustrated in fig. 1.

Embodiment:

Referring to Fig. 1 and 2, wherein schematically illustrate according to a kind of embodiment of drinking machine of the present utility model with the safety tap, comprise a valve body 1, it has the inner chamber 13 of an intake tunnel that is communicated with drinking machine heating container (not shown) 11, an exhalant canal 12 and a connection intake tunnel 11 and exhalant canal 12, and described inner chamber 13 is formed with a valve seat 14 that can match with a piston 2 with the connecting part of exhalant canal 12; One valve gap is fixed on described valve body 1 top, and it is made of with a back-up ring 8 that is fixed on described gland 3 inside a gland 3 that is screwed onto described valve body 1 top, and its guide ring 8 lower ends are fixed with a baffle plate 9; One valve rod 5 passes a through hole 81 and a through hole 93 that is formed on the described baffle plate 9 that is formed on the described back-up ring 8 respectively, and the inner of valve rod 5 and described piston 2 are fixed together, and the outer end of valve rod 5 and a main handle 4 are hinged; On the cylndrical surface of described valve rod 5, be equipped with one described piston 2 applied a Returnning spring 6 of bias voltage, make piston 2 have trend to the closing direction motion.

A notable feature of the present utility model is, between described main handle 4 and the described back-up ring 8, be provided with an assist handle 7 that can rotate relative to main handle 4, when described assist handle 7 rotates to primary importance, at least a portion of assist handle 7 is positioned at main handle 4 belows, causes main handle 4 to move, and makes tap keep closing, prevent that main handle 4 from being pressed by children accidentally, cause scald; Rotate to the second place and work as described assist handle 7, the breach and the main handle 4 that are formed on the assist handle 7 align, and allow to press main handle 4, the normal tap of handling.Described assist handle 7 can adopt horseshoe type, when it rotates to described primary importance, one side of horseshoe type leans below the projection 41 that main handle 4 stretches out downwards (referring to Fig. 2), and rotating to the described second place when it, the breach of horseshoe type and main handle 4 align, and allow operation main handle 4.

In a kind of preferred version, be fixed with a pin 71 on the described assist handle 7, it extends vertically, passes the corresponding arc-shaped slot 81 and 92 that is formed separately on back-up ring 8 and baffle plate 9 successively, and pin 71 lower ends are formed with a positive stop (referring to Fig. 1).In the space that forms between described back-up ring 8 and described baffle plate 9, be provided with the torsion spring 10 that a pair of described assist handle 7 applies unbalance loading, its end is fixed on the pin 91 that is formed on the described baffle plate 9, and the other end is fixed on the described pin 71.Its alternative is, an end of described torsion spring 10 is fixed on the described back-up ring 8, and the other end still is fixed on the described pin 71.Under torsion spring 10 drove, assist handle 7 had the trend of rotating to described primary importance, therefore did the time spent in no external force, can guarantee that tap do not opened by accident.

The foregoing description only for the usefulness that illustrates and understand the utility model, and is not to be to restriction of the present utility model, and scope of patent protection of the present utility model should be as the criterion with the content of claim.
