Description

The safety type water tap

Technical field

The utility model relates to water tap, and particularly a kind of safety type water tap is mainly used in household electric appliance such as drinking machine, hot-water bottle.

Background technique

At present, the various drinking machine that is used for that occurs on the market, the water tap of household electrical appliances such as hot-water bottle mostly exists certain unsafe factor, open switch because of carelessness such as children, cause scald etc., so people have invented safe water tap miscellaneous, for example the patent No. is that 00262760.4 model utility discloses a kind of safe water tap, the cavity of the bottom of its handle for constituting by two lower-left 1/4 plectanes, on the upper left corner of 1/4 plectane, small clevis pin with head is housed, suit locking plate on it, the top of locking plate is curved, and its curved gesture is consistent with the arc of handle, it is vertically tabular that the bottom of locking plate is, its base flushes with the end face of valve gap, and the button spring is housed on the small clevis pin with head, and this water tap has safe and practical, simple in structure, easy to operate advantage, but when pushing handle backward, still have current and come out.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of simple in structure, elegant in appearance and can effectively prevent the safety type water tap of misoperation.

The technological scheme that the utility model adopted is: the safety type water tap, has leading threeway, sealed valve core, valve shaft, the valve shaft spring, the tap lid, cock wrench and safety control bar, described sealed valve core, valve shaft is nested in leading threeway the inside successively according to the order of ecto-entad, the valve shaft spring housing is in the outside of valve shaft, one end withstands the valve shaft end, the other end withstands on the tap that is threaded with leading threeway and covers, described cock wrench is connected with the top pin of the valve shaft that stretches out the tap lid, the front portion of this cock wrench is shaped on a circular arc and pin is connected with a safety control bar, one torsion spring is housed on this bearing pin, a safety control lever lock not-go-end also is equipped with at the rear portion that it is characterized in that described cock wrench, its end is shaped on locking end hook, corresponding with the leading cover lock groove that tap covers, the rear corresponding to valve shaft in the cock wrench also is shaped on a spanner toward the rear position-arresting device.

Described leading threeway is shaped on screw thread and two round section joint ring grooves on an end that is connected with the water-supplying mouth.

The flange of described leading threeway is provided with a projection on the twelve-hour direction.

The spanner portion of described cock wrench and the intake pipe of leading threeway are perpendicular.

The beneficial effects of the utility model are: it is not only apparent to be contained in the anterior safety control bar of tap, and has only guaranteed that sealed valve core just can be opened under the situation that cock wrench and safety control bar are pinched simultaneously; The spanner of cock wrench one side is toward the rear position-arresting device, can prevent effectively that tap from when pusher, opening sealed valve core; Projection on the flange has been pinned tap in vertical position, has prevented leading bending; The cock wrench of vertical design makes more convenient to operate.

Embodiment

As Fig. 1, shown in Figure 2, present embodiment comprises leading threeway 1, sealed valve core 2, valve shaft 3, valve shaft spring 4, tap lid 5, the cock wrench 6 and the safety control bar 7 of spanner (handling knob) portion vertical design, described sealed valve core 2, valve shaft 3 is nested in leading threeway 1 the inside successively according to the order of ecto-entad, valve shaft spring 4 is enclosed within the outside of valve shaft 3, one end withstands valve shaft 3 ends, the other end withstands on the tap lid 5 that is threaded with leading threeway 1, described cock wrench 6 is connected with the top pin of the valve shaft 3 that stretches out tap lid 5, the front portion of this cock wrench 6 is shaped on a circular arc 6-1 and pin is connected with a safety control bar 7, one torsion spring 9 is housed on this bearing pin, after the power on the safety control bar 7 of being added in removed, safety control bar 7 can recover original state under the active force of torsion spring 9; Corresponding with the safety control bar, a safety control lever lock not-go-end 8 also is equipped with at the rear portion of cock wrench 6, its end is shaped on the sub-8-1 of a locking end hook, corresponding with the leading cover lock groove 5-1 on the tap lid 5, when not being subjected to external force, safety control bar 7 do not do the time spent, the sub-8-1 of locking end hook catches on leading cover lock groove 5-1, and this moment, cock wrench 6 can't lift valve shaft 3; The side plate on both sides, cock wrench 6 bottom forms a cavity, rear corresponding to valve shaft 3 in this cavity is shaped on a spanner toward rear position-arresting device 6-2, this stop bit device is a blend stop, links to each other with the side plate on both sides, and it can prevent that cock wrench 6 mistake backward operations from lifting valve shaft 3 to cause and leak; Described leading threeway 1 is shaped on screw thread 1-3 and two round section joint ring groove 1-4 that are used to place seal ring on an end that is connected with the water-supplying mouth.The flange 1-2 of described leading threeway 1 is provided with a protruding 1-2-1 on the twelve-hour direction, this projection embeds in drinking machine or the hot-water bottle, has pinned tap in vertical position, has prevented leading bending.

The working procedure of present embodiment is: as Fig. 3, shown in Figure 4, be subjected to the effect of external force when safety control bar 7 after, safety control lever lock not-go-end 8 is pushed out, the sub-8-1 of locking end hook also withdraws from from leading cover lock groove 5-1, at this moment, on cock wrench 6, add an external force and make it to turn forward that (cock wrench 6 is vertical design in the present embodiment, thereby significantly and easily pinch) than the spanner of " L " shape in the prior art, cock wrench 6 will lift, make valve shaft 3 compression valve shaft springs 4, and sealed valve core 2 lifted (as shown in Figure 4) from leading hole 1-1, at this moment water just can flow out.In case cock wrench 6 and safety control bar 7 have discharged, sealed valve core 2 and valve shaft 3 can be under the active forces of valve shaft spring 4, again with leading hole 1-1 sealing, and safety control bar 7 is under the effect of torsion spring 9, reply original state, safety control lever lock not-go-end 8 moves forward, and the sub-8-1 of locking end hook enters leading cover lock groove 5-1 simultaneously; At this moment, if pinch safety control bar 7 and cock wrench 6 simultaneously when promoting backward, promptly with opposite with normal operation (leaning forward), spanner will contact with valve shaft 3 toward rear position-arresting device 6-2, and stop cock wrench 6 to continue to promote, therefore, cock wrench 6 will can not lift valve shaft 3, and water is flowed out.
