Abstract

The utility model relates to a water tap which is composed of a casing, a screw cover, a guiding coil, a pushing block and a rubber pad. The casing is connected with a water pipe, and an outer screw thread of the guiding coil is screwed with the inner screw thread arranged at the upper part of the casing. The pushing block is fixed in the guiding coil, the rubber pad is affixed on a plane of the lower end of the pushing block, and is over against a water outlet arranged in the casing, and the screw cover is screwed with the inner screw thread of the guiding coil. The rise and fall of the pushing block is controlled by rotating the screw cover of the utility model, and thus the open and close of the water outlet arranged in the casing are driven by the rubber pad. The rubber pad is pressure resistant and wear resistant as compared with the traditional rubber ring, the contact area is big, and thus the sealing performance can be enhanced. When the rubber pad is worn out or leaked, only one rubber pad needs to be changed, and the cost is low as compared with changing the water tap. The utility model has the characteristics of labor saving and beauty.

Description

Telescopic water tap

The utility model relates to a kind of water tap.

The popular at present water tap majority that generally uses is the screw type rotary switch, discharging water, close must the rotating screw bolt handle, by the left and right sides knob plug of water tap the inside is blocked (or unclamping) water outlet realizes closing or opening of water tap, this opening/shutting mode all is worn plug, screw rod, nut easily, water leakage phenomenon often appears, need often to change water tap or parts, so be inconvenient to use.

The purpose of this utility model is to provide a kind of good seal performance, long service life, water tap with low cost.

The purpose of this utility model be achieved in that it by shell stop, spiral cover, guiding screwed pipe, jacking block, rubber cushion five parts form, housing and water pipe join, the outside thread of guiding screwed pipe and the internal thread on housing top spin, jacking block is fixed in the guiding screwed pipe, rubber cushion is bonded under the jacking block on the Transverse plane, over against the water outlet of enclosure interior, spiral cover spins with the internal thread of guiding screwed pipe.

The utility model with above structure is controlled rising and falling of jacking block by the turn spiral cover, opens and closes the interior water outlet of housing thereby drive rubber cushion.Because of rubber cushion than traditional cushion rubber withstand voltage wear-resisting, area of contact is big, thereby sealability improves greatly; When leaking when the rubber cushion wearing and tearing occurring, only need to change a rubber cushion, a water tap is with low cost a lot of than changing; And the utlity model has characteristics laborsaving, attractive in appearance.

Below in conjunction with accompanying drawing the utility model being carried out the ocean describes in detail bright:

Fig. 1 is an erection drawing of the present utility model.

Referring to Fig. 1, the utility model is made up of housing (1), spiral cover (2), guiding screwed pipe (3), jacking block (4), rubber cushion (5) five parts.Housing (1) is a main body, is engaged togather with it and water pipe, and other parts are formed tap in the collocation; Spiral cover (2) is used for controlling the size and the switch of leading water displacement; Guiding screwed pipe (3) is used for installing spiral cover, and fixedly jacking block and rubber cushion, and is spun on the housing; Jacking block (4) is used for controlling the telescopic level of rubber cushion, gives switch and regulates drainage rate; Rubber cushion (5) is used for stopping up water outlet, sealing draining, and extension and contraction control water displacement up and down.

Working principle: when the turn spiral cover, because threaded function, spiral cover will rise by (boiling water) or descend (Guan Shui).Counterclockwise during turn, then spiral cover rises, because the pressure effect of water, rubber cushion is pressed, and to rising, tap is in hull-borne, and it is big that water displacement becomes along with the rising of spiral cover; Clockwise during turn, then spiral cover descends, and is pushing away jacking block rubber cushion is moved down, and water displacement diminishes thereupon, when the turn spiral cover promotes rubber cushion to the inner water outlet surface of contact contact of tap the time with jacking block, seals this water outlet, and tap just is in closed condition.

Claims

1, a kind of telescopic water tap, it is characterized in that forming by housing (1), spiral cover (2), guiding screwed pipe (3), jacking block (4), rubber cushion (5), housing (1) joins with water pipe, the outside thread of guiding screwed pipe (3) and the internal thread on housing (1) top spin, jacking block (4) is fixed in the guiding screwed pipe (3), rubber cushion (5) is bonded under the jacking block (4) on the Transverse plane, and over against the inner water outlet of housing (1), spiral cover (2) spins with the internal thread of guiding screwed pipe (3).
