Description

Water tap joint device

Technical Field

The application belongs to a mechanical structure, and particularly relates to a faucet joint device.

Background

With the technological progress, more and more machine devices need to be externally connected with a water tap so as to be convenient for timely and intelligent water use, such as washing machines and the like. However, the existing faucet joint nozzle body often drops along with the conditions of prolonging the service time, aging and damaging the water pipe, shaking caused by water pressure change and the like, if nobody observes and pays attention to the faucet joint nozzle body in real time, water flows out all the time after the water pipe of the faucet joint drops, water resource waste is caused, and more importantly, potential safety hazards exist.

Disclosure of Invention

The purpose of the invention is as follows: to the problem that above-mentioned prior art exists, this application provides a tap piecing devices that can automatic stagnant water eliminates water wasting of resources and potential safety hazard.

The technical scheme is as follows: the application discloses a faucet joint device, which comprises a joint nozzle body and a water stop piece; the joint nozzle body comprises a water inlet section and a water outlet section, and the inner diameter of the water inlet section is larger than that of the water outlet section; the water stop piece consists of a pipe part accommodated in the water outlet section and a cover part clamped between the water inlet section and the water outlet section, and the pipe part of the water stop piece close to the cover part is in a hollow design; the length of the water stop pipe part is larger than that of the water outlet section of the joint nozzle body.

Furthermore, the cover part of the water stopping piece is circular, the diameter of the cover part is larger than the inner diameter of the water outlet section of the joint nozzle body and smaller than the inner diameter of the water inlet section of the joint nozzle body, and therefore the water stopping piece can play a role in blocking when needed.

Preferably, the device further comprises a sealing ring, wherein the sealing ring is arranged between the water stop cover part and the joint nozzle body. The sealing ring can be a rubber ring, and can be made of any known material capable of playing a sealing role.

Further, the pipe part and the cover part of the water stop piece are of detachable design. Specifically, the pipe portion extends two antennae towards the cover portion, the free end of each antenna extends outwards to form a convex block, and the water stop cover portion is correspondingly provided with a bayonet which can be matched and buckled with the convex block. The detachable design can facilitate the replacement of the water stopping cores with different diameters and different lengths, so that the water stopping core is suitable for the internal sizes of water pipe connectors with different models.

Furthermore, the water inlet section of the joint nozzle body is provided with threads for screwing the water tap.

Furthermore, the water outlet section of the joint nozzle body is in reducing arrangement and is used for being sleeved with a water outlet pipe. The reducing arrangement is convenient for increasing the firmness of the sleeving connection when the water outlet pipe is sleeved.

The size of each part can all set up according to market standard spare, also can do adaptability according to specific demand and adjust.

The working principle is as follows: when the water tap joint device is used, the water stopping pipe is firstly sleeved with the sealing ring and then placed in the water outlet section of the joint nozzle body, and the water stopping cover is arranged in the joint nozzle body. Then the water inlet section of the joint nozzle body is arranged on the corresponding water faucet, the external water outlet pipe is sleeved on the water outlet section of the joint nozzle body, the water stopping piece is jacked up, the water faucet is started, water flows in through the water inlet section of the joint nozzle body, and flows out after flowing into the water outlet section of the joint nozzle body through the hollow-out part of the jacked water stopping piece. When the external water outlet pipe falls off, the water stop cover part automatically presses the water outlet of the water receiving nozzle body under the water flow pressure of the water faucet, and the water outlet is blocked together with the sealing ring, so that the water flow is prevented from stopping when the water pipe falls off accidentally.

Has the advantages that: compared with the prior art, the water faucet joint device is simple and practical in structure, can realize timely water stopping after the water pipe is ensured to fall off through improved design, blocks a water outlet, prevents water flow after the water pipe is accidentally fallen off from being more than the phenomenon, eliminates potential safety hazards caused by the water pipe, and is obvious in effect.

Detailed Description

The present application will now be described in detail with reference to the drawings and specific examples.

A tap piecing devices as shown in fig. 1 and fig. 2, including the tubulose joint mouth body 1 and the water-stopping 5 of cover setting in the joint mouth body, wherein, the joint mouth body 1 is including the section 11 of intaking that is used for external tap and the play water section 12 that is used for external outlet pipe to the internal diameter of the section 11 of intaking is greater than a 12 internal diameters of play water section, and the section 11 of intaking is equipped with the screw thread in, the spiro union of being convenient for, and play water section 12 is reducing setting, and it is more firm to increase frictional connection when being convenient for the outside cup joints the water pipe. Referring to fig. 2, the water stop member 5 is composed of a tube portion 4 and a cap portion 2, wherein the diameter of the tube portion 4 is smaller than the inner diameter of the water outlet section 12 of the joint nozzle body, and the length of the tube portion is larger than the length of the water outlet section 12 of the joint nozzle body (at least 5mm beyond the water outlet section 12); the diameter of the cover part is larger than the inner diameter of the water outlet section 12 of the joint nozzle body and is smaller than the inner diameter of the water inlet section 11; two tentacles 42 extend upwards from the tube portion 4, and the free end of each tentacle 42 is provided with a convex block 42, and correspondingly, the cover portion 2 is provided with a bayonet 21 which can be matched and clamped with the convex block 42. The sealing ring 3 is arranged between the cover part 2 and the nipple body 1.

When the water tap joint device is applied between a water tap and a water receiving pipe of a washing machine, the pipe part 4 of the water stopping piece 5 is sleeved with the sealing ring 3 and is placed in the water outlet section 12 of the joint nozzle body 1, the pipe part 4 of the water stopping piece 5 is connected with the cover part 2 in a clamping mode, and then the water inlet section 11 of the joint nozzle body is connected with the water tap through threads. The water receiving pipe of the external washing machine is sleeved on the water outlet section 12 of the joint nozzle body through a joint (see general joints such as a 4-branch pipe and a 6-branch pipe which can be connected in the market), the water stopping piece 5 is jacked up by the internal structure of the water receiving pipe joint, the water faucet is started, water flows in through the water inlet section 11 of the joint nozzle body, and flows out after flowing into the water outlet section 12 of the joint nozzle body through the hollow part of the jacked water stopping piece 5. When the water receiving pipe of the washing machine drops, the water stopping piece cover part 2 automatically presses the water outlet of the water receiving nozzle body 1 under the pressure of water flow of the water faucet, and the water outlet is blocked together with the sealing ring 3, so that the water flow is prevented from stopping when the water pipe drops accidentally.
