Abstract
The utility model relates to a waterless self-locking tap, which comprises a tap body, a screw cap, a water tube, etc., wherein, the right upper end of the water inlet of the water tube is provided with a retractable rubber plug, the lower end of the rubber plug is made into a leather cup shape by the lower end of a top rod, the upper end of the top rod is provided with a cap-shaped top rod cap, and the lower end of a spring supports the upper end of the top rod cap; the lower end of a spring jaw clamps the lower end of the top rod cap, and a contact surface between the lower end of a spring jaw and the lower end of the top rod cap is cuneate. The utility model has reliable self-locking function, the utility model conducts self locking when no water exists, and when the water recovers, the utility model doesn't leak or drop; besides, the most parts of the utility model are made of ABS engineering plastics, and therefore, the cost of the utility model can be greatly reduced and metal can be saved.
Description
The utility model relates to a kind of anhydrous self-locking tap.
Chinese patent CN2144737Y has announced a kind of water-stopping self-closing tap, be one piston sealing device to be set, and push rod be set, can close automatically when under opening state, cutting off the water in the screw rod lower end in existing water tap bottom, its shortcoming is: close not tight, leakiness water droplet water.
The purpose of this utility model is to provide a kind of reliable in function, the anhydrous self-locking tap that locking effect is good.
For achieving the above object, the utility model adopts following technological scheme: it comprises faucet body, nut, water pipe etc., it is characterized in that: the positive upper end of the water intake of water pipe is provided with telescopic rubber stopper, the rubber stopper lower end is bowl-shape by top, push rod lower end cutification, top stem casing is installed in the faucet body, push rod can slide in the center hole of top stem casing, and the push rod upper end is provided with cap shape push rod cap, and the upper end of push rod cap is withstood in the spring lower end; The lower end of push rod cap is blocked in the lower end of spring detent, and the surface of contact between them is a wedge shape, and the upper end of spring and spring detent all is located on the nut, is connected for spiral between nut and the faucet body.The lower end overcoat jump ring of spring detent.
The utility model compared with prior art has advantage under the platform:
Auto-lock function is reliable, and self-locking when anhydrous is not leaked when coming water again, does not drip, and most of part can adopt the ABS engineering plastics to make, and can greatly reduce cost and save metal, and novel structure, easy to use, durable in use, acidproof, alkaline-resisting flexibly, oil resistant, corrosion-resistant.
Accompanying drawing is the utility model structural representation.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, the positive upper end of the water intake (11) of water pipe (10) is provided with telescopic rubber stopper (8), rubber stopper (8) lower end is bowl-shape by push rod (7) top, lower end cutification, top stem casing (6) is installed in the faucet body (9), push rod (7) can slide in the center hole of top stem casing (6), push rod (7) upper end is provided with cap shape push rod cap (4), and the upper end of push rod cap (4) is withstood in spring (3) lower end; The lower end of push rod cap (4) is blocked in the lower end of spring detent (2), and the surface of contact between them is a wedge shape, and the upper end of spring (3) and spring detent (2) all is located on the nut (1), is connected for spiral between nut (1) and the faucet body (9); The lower end overcoat jump ring (5) of spring detent (2); The elastic force of spring (3) is making a concerted effort less than hydraulic pressure and spring detent (2) elastic force greater than the elastic force of hydraulic pressure or spring detent (2).The utility model using method is as follows, in the time of as shown in the figure, it is the state that is out when water is arranged, when cutting off the water, because the elastic force of spring (3) is greater than the elastic force of spring detent (2), then spring (3) will eject push rod cap (4), push rod (7), reach rubber stopper (8) and block the self-locking purpose of water intake (11), when coming water again, because spring detent this moment (2) is inelastic to push rod cap (4), spring (3) continues to withstand push rod (7), make water can not pass through water intake (11), have only nut (1) is screwed onto the bottom, make spring detent (2) block push rod cap (4) again, then nut (1) is gone up and twisted, could open water tap again.
Claims (2)
1, a kind of anhydrous self-locking tap, it comprises faucet body, nut, water pipe etc., it is characterized in that: the positive upper end of the water intake (11) of water pipe (10) is provided with telescopic rubber stopper (8), rubber stopper (8) lower end is bowl-shape by push rod (7) top, lower end cutification, top stem casing (6) is installed in the faucet body (9), push rod (7) can slide in the center hole of top stem casing (6), and push rod (7) upper end is provided with cap shape push rod cap (4), and the upper end of push rod cap (4) is withstood in spring (3) lower end; The lower end of push rod cap (4) is blocked in the lower end of spring detent (2), and the surface of contact between them is a wedge shape, and the upper end of spring (3) and spring detent (2) all is located on the nut (1), is connected for spiral between nut (1) and the faucet body (9).
2, anhydrous self-locking tap according to claim 1 is characterized in that: the lower end overcoat jump ring (5) of spring detent (2).
