Description

The water tap automatic switch device

The utility model relates to the moving opening and closing device of a kind of fire hose head.

At present, many cities and urban residents are because lack of water water vat commonly used is equipped with water, forget that sometimes closing the fire hose women's head-ornaments thing takes place in the family by the phenomenon of water logging, and the resident family of own and lower floor has all been brought unnecessary economic loss, have wasted a large amount of water sources simultaneously.Sometimes be equipped with not go up water and cause and seeing to pour water in drink water difficulty or the water vat and wasted valuable time, and on market, also lose sight of the water tap that can address the above problem.

The purpose of this utility model provides a kind of simple in structure, and is easy to use, the device of automatic opening-closing water tap.

The purpose of this utility model is achieved in that on the valve rod base of water tap has fixed valve cap, the water tap valve rod is placed in the valve cap, on the valve cap inner valve stem, fixed sprocket wheel, sprocket wheel and cutter chain bar engagement, one end of chain is connected with the recovery pull bar, the box that reclaims pull bar is equipped with the recovery spring for outer one section, and the other end of chain is connected with the upper end of line of pull; Last dish is connected with hinge with the two ends of 4 groups of hinge expanders respectively with the chassis, and the center portion is fixed with support spring between last dish and the chassis, and the lower end of line of pull is connected with stayed mast, and the not end of stayed mast is connected with the joint pin of the right expander.

When the bucket on coiling on placing is filled water, be compressed at action of gravity lower support spring, the hinge expander is folded and descends and the pulling stayed mast, be connected in the line of pull pulling chain movement of stayed mast, chain drives the sprocket wheel clockwise direction that is fixed on the water tap valve rod and rotates, water tap is closed, and at this moment reclaims spring and is in confined state.When the water in the bucket is reduced to certain degree, under the effect of support spring, last dish promotes line of pull together with the bucket stayed mast that raises, reclaiming spring simultaneously produces elastic force outward and chain is spurred to counterclockwise direction, the water tap valve rod rotates in company with the sprocket wheel counterclockwise direction, water tap is opened, and has reached the purpose that opens and closes water tap.

Excellent beneficial effect of the present utility model is: the tap of 1, can fetching boiling water can be closed water tap again, and the water but also can avoid not irritating water of not only can having avoided waste reaches the effect of killing two birds with one stone.2, simple in structure, implement easily.3, cost is low, and many parts can utilize existing part on the market, can replace with braking string as line of pull, chain can utilize motorcycle chain, and water tap can utilize existing water tap on the market, only faucet valve pole socket and valve rod is done to change slightly to get final product, remaining parts is all simpler, easy processing.

Fig. 1 is a structural representation of the present utility model.Fig. 2 is the part schematic representation of a pair of hinge expander.Fig. 3 is the schematic top plan view of lower wall.Fig. 4 is the schematic top plan view of chain and sprocket wheel.Fig. 5 is the schematic representation of faucet valve pole socket and valve rod.

Below in conjunction with description of drawings embodiment of the present utility model: the water tap automatic switch device comprise reclaim pull bar (1), reclaim spring (2), chain (3), sprocket wheel (5), water tap (7), bucket (8), expander (10), stayed mast (11), supporting bullet (12), line of pull (14).On the valve rod base of water tap (7), fixed valve cap (6), faucet valve pole socket and valve rod are placed in the valve cap, on the valve cap inner valve stem, fixed sprocket wheel (5), sprocket wheel (5) and a cutter chain bar (3) engagement, the recovery pull bar (1) that penetrates in the valve cap in the face of one end of chain (3) and valve cap left side is connected, recovery spring (2) is housed reclaiming one section that pull bar (1) stretches out valve cap outside, the upper end that penetrates the line of pull (10) in the box in the other end of chain (3) and the hole of valve cap left surface is connected, at this, recovery pull bar (1) and line of pull (14) the chain holder all the time and are play supporting role, and do not make chain break away from sprocket wheel; Last dish (9) is connected with hinge with the two ends of 4 groups of hinge expanders (10) (hinge) respectively with chassis (13).A slice of this expander has one section protruding section at its end of tearing the place's of closing hinge open, so this expander (hinge) has only an inside direction to amount to.The center portion is fixed with support spring (12) between last dish (9) and chassis (13); The lower end of line of pull (14) is connected with stayed mast (11) by the connecting tube (16) in the resistance trombone slide (15), stayed mast (11) is that an end has connecting ring, the threaded straight-bar of the other end, its connecting ring is connected with the joint pin that the right expander (10) is amounted to the position, and its end passes the radial hole of expander joint pin intermediate portion, the left side and being threaded of connecting tube (16).The bottom surface right-hand member centre bit of valve cap (6) be equipped with one with corresponding hexagon of valve rod base profile or square mounting hole, its left surface has and sprocket wheel height and joint enclose corresponding two sliding eyes of width.

Last dish (9) and chassis (13) are garden shape or square metal dish or duroplasts dish, edge and front and rear side about last dish (9) along the fritter catch is all arranged or go up dish (9) for around the dish of surrounding edge is arranged, in order to avoid bucket landing, the porose fixed plate of 4 group switching centres of all around correspondence is all arranged on the top of the bottom of last dish (9) and chassis (13), and 3 or 4 supporting legs are arranged at the bottom of lower wall (13).
