Detailed Description
In order to further explain the technical scheme of the invention, the invention is explained in detail by specific examples.
Referring to fig. 1 to 3, there is provided a rotary built-in faucet coupling according to the present invention, which is convenient to assemble, comprising an inner tube 10 and an outer tube 20, wherein the inner tube 10 has a connection end 11 for fixedly connecting with a faucet body, the inner tube 10 has a first through hole 12, the outer tube 20 has a second through hole 21 connected with the first through hole 12 and forming a water flow passage together, and the inner tube 10 has a shaft portion 13 inserted into the outer tube 20, and the above-mentioned features are substantially the same as those of the prior art and will not be described in detail herein.
The core improvement point of the invention is that the outer pipe 20 adopts a split structure, in particular to an upper pipe section 22, a lower pipe section 23 and a sliding sleeve 24, wherein the upper pipe section 22 is provided with a connecting part 221 for fixedly connecting with a water outlet pipe, the upper end of the lower pipe section 23 is abutted against the upper pipe section 22, the lower end of the lower pipe section 23 is sleeved on the periphery of the inner pipe 10, the upper pipe section 22 is provided with a through part 222, the through part 222 is used for installing a ball 30 from outside to inside, so as to be abutted against the shaft rod part 13, and the sliding sleeve 24 is slidably sleeved on the upper pipe section 22 and blocks the inlet of the through part 222.
In this way, the present invention relates to a rotary built-in tap joint which is convenient to assemble, when assembling, the upper outer tube 20, the sliding sleeve 24, the lower outer tube 20, the metal spring plate 50, the inner tube 10, etc. are assembled, and then the ball 30 is installed, because the upper outer tube 20 is formed with the through part 222, the ball 30 can be installed from outside to inside, the ball 30 is plugged into the through part 222 until being abutted against the shaft rod part 13 of the inner tube 10, after all the required ball 30 is 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 part 222, which is the inlet when the through part 222 is assembled with the ball 30, thus completing the assembly of the whole tap joint.
Compared with the prior art, the ball 30 is installed from outside to inside, so that the assembly efficiency is greatly improved, and the cost of a single product is reduced.
In this embodiment, the through portion 222 is an annular through groove disposed annularly along the circumference of the upper pipe section 22. The core purpose of the through portion 222 is to achieve convenient installation, that is, to install the ball 30 from outside to inside, as to whether it adopts a complete groove structure, or a plurality of holes formed at intervals, or a part of groove portions Kong Douhang, so long as the inner and outer through can be achieved, and the ball 30 can be installed conveniently.
Preferably, the shaft portion 13 is further formed with an abutment limit groove 131 at a position corresponding to the through portion 222, and a sum of a depth of the abutment limit groove 131 and a depth of the through portion 222 is equal to a diameter of the ball 30. Thus, after the ball 30 is mounted, the positions of the balls 30 are relatively fixed, so that the rotation supporting function of the balls 30 is exerted.
As a specific embodiment of the sliding sleeve 24 being slidably disposed on the upper pipe section 22 and blocking the entrance of the through portion 222, the sliding sleeve 24 is disposed outside the upper pipe section 22 and also disposed inside the lower pipe section 23, as shown in fig. 2 and 3, when the ball 30 needs to be installed, the sliding sleeve 24 is located at a first relatively lower working position, and when the ball 30 is installed, the sliding sleeve 24 is located at a second relatively upper working position, which is a simplest structure for positioning the sliding sleeve 24:
The sliding sleeve 24 is positioned with the upper pipe section 22 and the lower pipe section 23 through the sealing ring 40, the sealing ring 40 is used for sealing the gap between the connecting part 221 and the water outlet pipe, namely, when the ball 30 is installed, the width of the sealing ring 40 is used as a support, and the flange part 241 on the sliding sleeve 24 and the supporting relation of the sealing ring 40 allow the sliding sleeve 24 to be accurately positioned due to the sealing ring 40.
Preferably, as a preferred embodiment of the fixed connection between the outer tube 20 and the water outlet tube, the outer tube 20 is further provided with a clamping port 231 and is fixedly connected with the water outlet tube through a clamping seat, the clamping seat is a metal elastic sheet 50, the metal elastic sheet 50 is in a C shape, and a boss 51 is further provided in the middle of the metal elastic sheet 50.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
