Abstract

A tap that is opened once pressed and automatically closed once released, wherein the gate valve in the water channel of the tap is closed at the top; below the gate valve, a spring is provided; under the action of the spring, the gate valve can automatically shutoff the water channel, and when pressed down by the link lever, the gate valve opens the channel.

Description

A kind of self-closing type water tap

The utility model belongs to a kind of water tap.

Before the utility model was worked it out, general water tap adopted rotary type or spiral shaft type switch, and these two kinds of water taps are all perishable, and spiral shaft type water tap will rotate a few when using, and Chang Yinwei closes the waste that causes water.

The purpose of this utility model is to provide a kind of one by promptly opening, and the water tap that can close automatically to reduce the waste of water, prolongs the working life of water tap, and reduces manufacture cost again.

The utility model is finished purpose in the following manner: a valve is set on the water tap internal water channel, and valve can be closed water channel automatically under the elastic material effect, just opens water channel under external force.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Figure l is the half-open shape sectional arrangement drawing of the utility model concrete structure (except the spring).

Fig. 2 is that the A of figure l is to view.

Fig. 3 is that the oblique tongue of arc, location card and location are latched in the B of Fig. 1 to amplification rearview.

Be most preferred embodiment of the present utility model below:

With reference to Fig. 1: swivel body [1] is made by metal or non-metal solid, on connecting rod movable span [2] is arranged, loam cake hole [3], inner water channel [4], [5], [6] that link to each other that form.Water channel [5] upper diameter is smaller, forms a bayonet socket [7] with the bottom, and to withstand valve [8], valve [8] must work to close water channel easily in water channel [5] bottom activity when being adjacent to bayonet socket [7].Valve [8] is upwards withstood by the spring that is difficult for getting rusty [9], valve [8] and connecting rod L10] link to each other (being made of one in this example), connecting rod [10] can only rotate and slide up and down in connecting rod movable span [2].It under the spring [9] lid [11], its internal diameter is identical with water channel [5] bottom internal diameter, the outside and loam cake hole [3] are with the spiral interlock, shell [1] is made the oblique tongue of arc [13] of a slice or two band location cards [12] in connecting rod movable span [2] below, to block the location door bolt [14] that is embedded on the connecting rod [10], stop valve [8] to automatically reset, finish long-time unlatching.During assembling with connecting rod L10], valve [8] and spring [9] are successively put into by loam cake hole [3], screw on and cover L11] get final product.Press lower link [10] during use, valve [8] is promptly opened, and water channel is unimpeded, decontrols connecting rod [10], and valve [8] is promptly closed water channel automatically; In the time of will opening for a long time, depress connecting rod [10] back and slightly rotate, location door bolt L14] be stuck in location card [12] and go up and get final product

, the connecting rod [10] that slightly reverses in the time of not, location door bolt [14] promptly breaks away from location card [12].Water tap joins with pipeline in a spiral manner.Method for making is identical with spiral shaft type water tap.

Claims

A kind of self-closing type water tap, comprise the oblique tongue of arc [13] of shell [1], valve [8], spring [9], lid [11], band location card [12] and the connecting rod [10] of band location door bolt [14], it is characterized in that having on it inner water channel that links to each other that forms of shell [1] of connecting rod movable span [2], loam cake hole [3], connecting rod [10] penetrates from the connecting rod movable span, and the lower end of connecting rod is to be between lid [11], valve [8] and the lid [11] spring to be housed on valve [8], loam cake hole [3].
