Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to a faucet joint. Background Art

[0002] The faucet is an indispensable device in people's daily life. The existing faucet has a simple structure. When it is damaged, water will leak directly from the water pipe, causing great trouble to people. At the same time, when the faucet is replaced, water will also leak, causing trouble for the operator.

[0003] Therefore, a faucet joint becomes a problem that people need to solve urgently. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a faucet joint which can prevent the water flow in the water pipe from leaking wantonly when the faucet is damaged.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a faucet joint, comprising a connecting head and a piston; the connecting head comprises a water inlet part, a limiting part and a water outlet part which are connected in sequence and formed in one piece; the inner diameter of the water inlet part is larger than that of the limiting part, and the inner diameter of the limiting part is larger than that of the water outlet;

[0006] The piston comprises an outer seal and an inner seal, wherein the outer seal diameter matches the inner diameter of the water inlet, and the inner seal diameter matches the inner diameter of the limit portion; when the piston seals the connector, the outer seal is at the water inlet and the inner seal is at the limit portion.

[0007] Furthermore, an inclined platform is provided at the connection between the water inlet portion and the limiting portion, and a transition inclined surface parallel to the inclined surface of the inclined platform is provided at the connection between the outer plugging and the inner plugging.

[0008] Furthermore, the tilting platform tilts from the water inlet side to the limiting side so that the inner diameter of the connector gradually decreases.

[0009] Furthermore, a thickness difference between the water inlet portion and the limiting portion is greater than a thickness difference between the limiting portion and the water outlet portion.

[0010] The advantage of the present invention over the prior art is that after the faucet is damaged or disassembled, the present invention can automatically press the piston into the limiting part of the connector by water flow pressure, thereby blocking the water flow and effectively preventing uncontrolled and wanton leakage of water.

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inside", "outside", "vertical", "circumferential", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0016] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The following is a further detailed description of a faucet connector of the utility model in conjunction with the accompanying drawings.

[0018] Combined with Figure 1-3 , the utility model is introduced in detail.

[0019] Overall structure: The faucet connector of the utility model mainly includes two parts: a connector 1 and a piston 2; the connector 1 is composed of a water inlet part 101, a limit part 102 and a water outlet part 103 which are connected in sequence and integrally formed, and the transition between the parts is smooth without obvious seams.

[0020] Water inlet 101: As the inlet part of the joint, its inner diameter is designed to be relatively large to facilitate smooth water flow.

[0021] The limiting portion 102 is located between the water inlet portion 101 and the water outlet portion 103 , and has an inner diameter slightly smaller than that of the water inlet portion 101 . It is used to limit the movement position of the piston 2 and enhance the sealing effect after the faucet is disassembled.

[0022] Water outlet 103: As the outlet part of the joint, it has the smallest inner diameter, ensuring that the water flow is subjected to a certain pressure when passing through, thereby improving the water outlet efficiency.

[0023] Design of piston 2: Piston 2 is a key component for achieving sealing in the present invention, and is composed of two parts: an outer seal 201 and an inner seal 202.

[0024] External plug 201 : its diameter matches the inner diameter of the water inlet 101 .

[0025] Inner seal 202: Its diameter matches the inner diameter of the limiting portion 102. The inner seal 202 plays a role in further stabilizing the position of the piston 2 and enhancing the sealing performance in the limiting portion 102.

[0026] Special structure design:

[0027] Inclined platform 104 and transition slope 203: Inclined platform 104 is provided at the connection between water inlet 101 and limiter 102. Inclined platform 104 gradually slopes from the water inlet 101 side to the limiter 102 side, so that the inner diameter of connector 1 gradually decreases. Accordingly, a transition slope 203 parallel to the slope of inclined platform 104 is provided at the connection between outer seal 201 and inner seal 202 of piston 2. This design not only enhances the sealing between piston 2 and connector 1, but also makes piston 2 smoother during movement, reducing friction and wear.

[0028] Thickness difference design: the thickness difference between the water inlet part 101 and the limiting part 102 is greater than the thickness difference between the limiting part 102 and the water outlet part 103. This design not only optimizes the overall structure of the joint, but also enables the piston 2 to fit more closely to the inner wall of the connector 1 when sealing, thereby improving the sealing effect.

[0029] The specific implementation process of the faucet connector of the utility model is as follows:

[0030] After connecting the faucet to the connector of the utility model and then connecting the water pipe, the connecting end of the faucet will push the piston 2 backwards, and at this time, the water flow can flow into the faucet normally; when the faucet is broken, damaged or falls off, the impact force of the water flow will push the piston 2 to the water inlet part 101 and the limit part 102 of the connector 1, which can effectively prevent water leakage in the water pipe.

[0031] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
