CRANK CONNECTION STRUCTURE AND FAUCET USING THE STRUCTURE

Abstract

A crank connection structure includes a crank and a connection pipe. The crank and the connection pipe are connected in a plug-in manner and are rotatable relative to each other. A sealing ring is provided between the crank and the connection pipe. A faucet includes a body and the crank connection structure. The connection pipe is connected to the body. For the crank connection structure and the faucet using the structure, during the installation, only the angle relationship between the crank and the connection pipe needs to be adjusted, and the sealing ring is used for sealing the crank and the connection pipe without requiring raw material belt. The angles between the faucet body and the two cranks can be simultaneously adjusted to be at same level by rotating the faucet body, which abandons the traditional way of separately adjusting the cranks for leveling, achieving faster installation and adjustment.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Specific embodiments of the present disclosure are further described in detail with reference to the accompanying drawings below. In the drawings,

[0021] FIG. 1 is an exploded view of a crank connection structure according to an embodiment of the present disclosure; and

[0022] FIG. 2 is a schematic structural view of a faucet according to an embodiment of the present disclosure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

First embodiment

[0023] As shown in FIG. 1, a crank connection structure is provided, which includes cranks 1 and a connection pipe 2. The connection pipe 2 may be used for connection with a water supply port inside the wall, and may also he used for connection with a water inlet of a faucet body 4. The cranks 1 and the connection pipe 2 are connected in a plug-in manner and are rotatable relative to each other, and a sealing ring 3 is provided between the crank 1 and the connection pipe 2. During the installation process, only the angle relationship between the crank 1 and the connection pipe 2 needs to be adjusted, and the sealing ring 3 is used for sealing the crank 1 and the connection pipe 2 without the use of raw material belt, thus avoiding the problem that the raw material belt is easily loosened and worn, and improving the sealing effect.

[0024] Further, the connection pipe 2 includes a first mounting hole, and an end of the crank 1 is rotatably plugged into the first mounting hole. The crank 1 includes a first pipe portion and a second pipe portion, which are communicated with each other and are eccentrically arranged. The crank 1 is adjusted in width and level with the adjacent crank by rotating in the first mounting hole.

[0025] Further, the crank 1 is provided with a second groove for receiving the sealing ring 3. The sealing ring 3 is mounted on the crank 1, and may be conveniently detached and replaced.

[0026] Further, a depth at which the crank 1 and the connection pipe 2 are plug-connected is adjustable. Typically, there is no uniform or precise specification for the extending distance of the water outlet joint on the wall. Hence, the mounting operation can be completed smoothly by properly adjusting the depth at which the crank 1 and the connection pipe 2 are plug-connected.

[0027] As shown in FIG. 2, a faucet is provided, which includes a body 4 and the above-described crank connection structure. One end of the connection pipe 2 connected to the body 4 is connected onto the body 4, and the other end is connected onto the crank 1. One end of the connection pipe 2 connected to the water supply port inside the wall is connected onto crank 1, and the other end is connected onto the water supply port inside the wall. The connection pipe 2 connected to the water supply port inside the wall may be a water supply pipe. The connection pipe 2 may be screwed onto the body 4, or may also be integrally formed with the body 4. In this solution, the angles between the faucet body 4 and the two cranks 1 can be simultaneously adjusted to be at the same level by rotating the faucet body 4, which abandons the traditional way of separately adjusting the cranks 1 for leveling, thereby achieving faster installation and adjustment.

Second Embodiment

[0028] This embodiment differs from the first embodiment in that, the connection pipe 2 includes a first mounting hole, and an end of the crank 1 is rotatably plugged into the first mounting hole. The first mounting hole is provided with a first groove for receiving the sealing ring 3. The sealing ring 3 is mounted on the connection pipe 2.

Third Embodiment

[0029] This embodiment differs from the first embodiment in that, the crank 1 includes a second mounting hole, and an end of the connection pipe 2 is rotatably plugged into the second mounting hole.

[0030] Further, the second mounting hole is provided with a third groove for receiving a sealing ring 3. The sealing ring 3 is mounted on the crank 1.

Fourth Embodiment

[0031] This embodiment differs from the first embodiment in that, the crank 1 includes a second mounting hole, and an end of the connection pipe 2 is rotatably plugged into the second mounting hole. The connection pipe 2 is provided with a fourth groove for receiving the sealing ring 3. The sealing ring 3 is mounted on the connection pipe 2.

[0032] The above-mentioned embodiments are only used to illustrate the technical solutions of the present disclosure, and are not intended to limit the present disclosure. Any modification or equivalent substitution made without departing from the spirit and scope of the present disclosure will fall within the scope of the technical solutions of the present disclosure.
