The valve is used to control the entire faucet to be in a closed state and a water outlet state. The faucet body is connected to the water outlet pipe through a joint. Since the water outlet pipe needs to face different positions according to actual water usage, the water outlet pipe needs to be rotatable.

[0003] The Chinese patent document CN207777840U applied for and announced by the applicant discloses a rotating built-in faucet joint, wherein the inner tube and the outer tube also include a plurality of first balls and a plurality of second balls located between the inner tube and the outer appearance, the inner tube has a shaft portion inserted into the outer tube, and a first annular groove and a second annular groove are respectively formed between the shaft portion and the inner wall of the outer tube, and the first annular groove and the second annular groove together form an annular groove for accommodating a plurality of first balls. It does not get stuck like the traditional technology, and it is also very stable in use. However, in the actual production process, when the assembly workers install the first balls into the shaft portion and the inner wall of the outer tube, there is a defect of low assembly efficiency, which directly causes the cost of a single product to be unable to be further reduced.

[0004] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Summary of the invention

[0005] The main purpose of the present invention is to provide a rotating built-in faucet joint which is easy to assemble, so as to solve the problem of low efficiency in placing a ball in an annular groove on the inner wall of an outer tube in the prior art.

[0006] In order to achieve the above object, the solution of the present invention is:

[0028] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0029] like Figures 1 to 3 As shown, the present invention relates to a rotating built-in faucet joint that is easy to assemble, including an inner tube 10 and an outer tube 20. The inner tube 10 has a connecting end 11 for being fixedly connected to the faucet body, the inner tube 10 has a first through hole 12, and the outer tube 20 has a second through hole 21 connected to the first through hole 12 and together forming a water flow channel; the inner tube 10 has a shaft portion 13 inserted into the outer tube 20. The above features are basically the same as the functions and structures of the prior art, and will not be described in detail here.

[0030] The core improvement of the present invention is that the outer tube 20 adopts a split structure, specifically, it has an upper tube section 22, a lower tube section 23 and a sliding sleeve 24, the upper tube section 22 is provided with a connecting portion 221 for being fixedly connected to the water outlet pipe, the upper end of the lower tube section 23 is abutted against the upper tube section 22, and the lower end of the lower tube section 23 is sleeved on the periphery of the inner tube 10; the upper tube section 22 is formed with a through portion 222, and the through portion 222 is for the ball 30 to be installed from the outside to the inside, so as to abut against the shaft portion 13, and the sliding sleeve 24 can be slidably sleeved on the upper tube section 22 and block the entrance of the through portion 222.

[0031] Thus, the present invention relates to a rotating built-in faucet joint that is easy to assemble. When assembling, the upper outer tube 20, the sliding sleeve 24, the lower outer tube 20, the metal spring 50 and the inner tube 10 are assembled first, and then the ball 30 is installed. Since the upper outer tube 20 is formed with a through portion 222, the ball 30 can be installed from the outside to the inside. The ball 30 is inserted inward through the through portion 222 until it abuts against the shaft portion 13 of the inner tube 10. When all the required balls 30 are installed, the sliding sleeve 24 is moved so that the sliding sleeve 24 can block the outlet of the ball 30 leaking from the through portion 222. The outlet is the entrance when the through portion 222 is assembled with the ball 30, and the assembly of the entire faucet joint is completed.

[0032] Compared with the prior art, the present invention adopts an installation method from outside to inside for the installation of the ball 30, which greatly improves the assembly efficiency and reduces the cost of a single product.

[0033] In this embodiment, the through portion 222 is an annular through groove annularly arranged along the circumference of the upper tube section 22. The core purpose of the through portion 222 is to facilitate installation, that is, to install from the outside to the inside, and it can be a complete groove structure, a plurality of holes formed at intervals, or a partial groove and a partial hole, as long as it can achieve internal and external penetration and facilitate the installation of the ball 30.

[0034] Preferably, the shaft portion 13 is further formed with a stop groove 131 at a position corresponding to the through portion 222, and the sum of the depth of the stop groove 131 and the depth of the through portion 222 is equal to the diameter of the ball 30. In this way, when the ball 30 is installed, the position of the ball 30 will be relatively fixed, so that the rotation support function of the ball 30 can be fully exerted.

[0035] As a specific embodiment in which the sliding sleeve 24 can be slidably mounted on the upper pipe section 22 and block the entrance of the through portion 222, the sliding sleeve 24 is mounted outside the upper pipe section 22 and also mounted inside the lower pipe section 23. Please refer to Figure 2 and Figure 3 As shown, when the ball 30 needs to be installed, the sleeve 24 is located at a first working position relatively below, and when the ball 30 is installed, the sleeve 24 is located at a second working position relatively above. This is the simplest structure for positioning the sleeve 24:

[0036] The sliding sleeve 24 is positioned between the upper pipe section 22 and the lower pipe section 23 by a sealing ring 40. The sealing ring 40 is a sealing ring 40 used to seal the gap between the connecting portion 221 and the water outlet pipe. That is, when the installation of the ball bearing 30 is completed, the sealing ring 40 is installed and the width of the sealing ring 40 is used as support. The supporting relationship between the flange portion 241 on the sliding sleeve 24 and the sealing ring 40 allows the sliding sleeve 24 to be accurately positioned.

[0037] Preferably, as a preferred embodiment in which the outer tube 20 is fixedly connected to the water outlet pipe, a card interface 231 is also provided on the outer tube 20, and is fixedly connected to the water outlet pipe through a card seat, and the card seat is a metal spring 50, and the metal spring 50 is C-shaped, and the middle part of the metal spring 50 also has a boss 51.

[0038] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
