Abstract

The utility model relates to a tap with a number checking locking device. A number checking locking device which is arranged above the valve shaft of a tap is used for opening and closing the water. The structure of the number checking locking device is that the interior of an external ring switch whose top end is provided with numbers is sheathed with a rotary body whose upper end is provided with graduation marks, and the rotary body is sheathed and engaged with the valve shaft. An internal ring switch whose upper end is provided with the numbers and a small flange for clamping a bolt in the rotary body is sheathed in the rotary body. When the numbers on the internal ring and the external ring are rotated to the mark position which is needed and is the same with the set position, the tap can be opened or closed. The tap is suitable for being mounted outdoors so as to prevent the other people from abusing the water.

Description

Tap with number checking locking device

The utility model relates to a kind of water tap that the check mark locking device is arranged, and especially suits to use at the outdoor open and close water of doing.

Water tap without is anti-public's abuse at present, often switch handle being shirked the back from water tap puts in addition, during use switch handle is placed in and opens water tap (seeing shown in Figure 1) on the valve shaft, the shortcoming of this structure: be easy to lose after (1) switch handle shirks.(2) need not use special-purpose switch handle, any instrument that makes it to rotate as long as can be placed in valve shaft all can be opened water tap, even special-purpose switch handle also all is general, therefore one of anyone portability can not prevent the purpose that other people abuse.

The purpose of this utility model is interior ring switch and set flange and the circular groove of outer shroud switch that a kind of utilization of design has number, cooperate the latch in the solid of rotation again, when number forwards required mark position to, with set identical the time could the rotary swivel valve shaft the water tap with check mark locking device.

switch 23 in solid of rotation 22 and one, wherein outer shroud switch 21 tops are provided with tactic 10 numbers of 0-9, and the centre of outer shroud switch 21 is provided with a circular groove 211, a positive inverted draw cut 210 bigger than circular groove 211 diameters established in these circular groove 211 tops, ccontaining solid of rotation 22 in it, bottom land at circular groove 211 is provided with an open-work 212, valve shaft 11 can be run through and with solid of rotation 22 sockets, be provided with two small cylindrical tanks 213 and 214 that cooperate the number permutation on outer shroud switch 21 tops in open-work 212 outsides, for making check mark locking device 2 when checking the number, the number on the number on outer shroud switch 21 tops and interior ring switch 23 tops, have only one group of corresponding number can open water tap, therefore wherein a small cylindrical tank 213 is located on the number, 214 centres of being located at any two numbers of another small cylindrical tank avoid two sets of numbers all can open the situation of water tap.Solid of rotation 22 be in the middle of having in one circular groove 223 and in circular groove 223 both sides, two small cylindrical tanks 222 that diameter is less, the top of solid of rotation 22 then is provided with a bulge loop 221, when utilizing this bulge loop 221 can make solid of rotation 22 place the circular groove of outer shroud switch 21, can block positive inverted draw cut 210 and make the bottom of the unlikely contact cylinder 211 in bottom of solid of rotation 22, be provided with the scale mark of relative one of them small cylindrical tank 222 vertical corresponding position on the surface of bulge loop 221, be provided with a perforation 224 more less than the diameter of small cylindrical tank 222 in the bottom of each small cylindrical tank 222, and 224 bottoms that are through to solid of rotation 22 of boring a hole, the position of this perforation 224 then cooperates the small cylindrical tank 213 and the 214 set positions of above-mentioned outer shroud switch 21, a spring 225 is respectively arranged in two small cylindrical tanks 222, above spring 225, establish a latch 226, latch 226 has two sections different latch diameters, less one section of diameter runs through spring 225, bigger one section then a little protrudes the top of small cylindrical tank 222 to diameter, bottom land at circular groove 223 is provided with a dentation open-work 227 that cooperates dentation valve shaft 11, these dentation open-work 227 meshing valve shafts 11 that entangle, when treating that solid of rotation 22 rotates, driven valve shaft 11 rotations.In ring switch 23 tops have equal angles and meet odd numbers or flange 231 that even numbers distributes is checked the number for rotation, on flange 231 and two flanges 231 between recessed shelves in all be provided with numeral, this numeral distributes in proper order with the 0-9 isogonism, below flange 231, be provided with two little flanges 232, the position that this little flange 232 is set, corresponding with the small cylindrical tank 213 of outer shroud switch 21 and 214 set positions, in the middle of interior ring switch 23, establish a circular groove 233, establish an open-work 234 littler at the groove bottom of circular groove 233 than circular groove 233 diameters, run through for valve shaft 11, a volute spring 235 places circular groove 233, the end that volute spring 235 external diameters are bigger places on the formed blocked part 236 of diameter difference of circular groove 233 and open-work 234, the volute spring the other end is then established a screw 237, this screw 237 locks with the interior threaded hole 12 of valve shaft 11, and then compressing volute spring 235 is established a cap 238 at the top of circular groove 233 and is covered with ring switch 23 in pressing solidly.During assembling, with the small cylindrical tank 213 of outer shroud switch relative number to the scale on the bulge loop 221 of last solid of rotation 22, the person that in addition the little flange 232(of interior ring switch 23 aligned the number) is threaded to and aligns the number that outer shroud switch 21 sets, because of the perforation 224 of solid of rotation 22 and in little flange 232 its position angles of ring switch 23 all consistent with the small cylindrical tank 213 of outer shroud switch 21, can press down latch 226 by little flange 232, latch diameter less one section is inserted in the small cylindrical tank 213 of outer shroud switch 21 (shown in Figure 6), only need this moment rotation outer shroud switch 21 can utilize latch 226 driven rotary bodies 22 to rotate, and then utilize dentation open-work 227 in the solid of rotation 22 to drive valve shafts 11 rotations and water tap is opened or closed.After closing water tap, ring switch 23 staggers relative number in only needing to rotate, the little flange 232 of ring switch 23 departs from the small cylindrical tank 222 of solid of rotation 22 then, latch 226 upspring (shown in Fig. 6 b), at this moment, latch 226 breaks away from fully with the outer shroud switch, and promptly the outer shroud switch can only dally this moment, and the tap of can't driven rotary body 22 fetching boiling water.
