Faucet outlet pipe assembly structure

The invention relates to a faucet structure, which refers to a faucet outlet pipe assembly structure.

According to the faucet structure in some places, in order to extend the scope of water use, an outlet pipe will be installed to extend the water to a farther place, but the outlet pipe will not hinder the use process and more convenient use. Therefore, the outlet pipes are all arranged to be rotatable to rotate the angle and position of the water outlet pipe. At present, the faucet is combined with the water outlet pipe structure. As shown in Figures 7 and 8, the faucet body 60 is provided with a control handle 61 at a side position thereof. The faucet body 60 is provided with a coupling groove chamber 62. One end of the outlet pipe 70 forms a coupling portion 71. The coupling portion 71 is provided with at least one set of ring grooves 711 for assembling the water stop ring 72, and the periphery of the coupling portion 71 is provided. The fixing ring groove 712 is provided with a C-shaped buckle 73, and the screw hole 63 is provided on the peripheral side of the faucet body 60. When the faucet body 60 is combined with the water outlet pipe 70, the connecting portion 71 of the water outlet pipe 70 is connected. It is disposed in the coupling groove chamber 62 of the faucet body 60, and is locked with the screw hole 63 of the faucet body 60 by using the bolt 64, so as to achieve the structure of the conventional faucet combined with the water outlet pipe.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reason is as follows: When the faucet body 60 is used, the screw hole 63 and the bolt 64 can be clearly seen, which is easy to cause the surface of the faucet body 60. Less aesthetically pleasing; again, the conventional faucet body 60 When the water outlet pipe 70 is combined, only the bolt 64 is used to reach the faucet body to lock and press the water outlet pipe 70, and only a little locking force is used, which may easily cause the bolt 64 to loosen under the long-term use condition, and the outlet pipe 70 is The C-shaped buckle 73 is pressed against the bolt 64. Although the outlet pipe 70 can be restrained from falling off and has a rotating effect, the C-shaped buckle 73 is easily pressed against the bolt 64 to be compressed and destroyed, and is discharged from the water pipe. 70 Long-term rotary friction, there will be more wear and tear, resulting in the C-type buckle 73 between the outlet pipe 70 and the combined groove chamber 62 to create a gap, and then there are doubts of shaking, falling off, resulting in reduced structural life, lack of practical Sex.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention is to provide a faucet outlet pipe assembly structure for the above-mentioned shortcomings existing in the prior art.

The utility model relates to a faucet outlet pipe assembly structure, which comprises: an outlet pipe, a connecting seat, a locking ring and a coupling seat, wherein the bottom of the outlet pipe has a plug portion and a block at the upper end of the plug portion a retaining portion, the outer ring of the plug portion is provided with at least one sliding slot and a plurality of annular grooves, and O-rings are sequentially sleeved in the annular grooves, and the outer diameter of the blocking portion is larger than the insertion portion, and the blocking portion The bottom of the stop portion is provided with a recessed groove in the inner ring, the connecting seat has a connecting sleeve and a connecting stud integrally extending from the bottom of the connecting sleeve, the connecting sleeve has a hollow interior having an accommodating space, and the outer wall is ring-shaped a threaded section, and at least one through hole in the threaded section is in communication with the accommodating space, and the through hole is assembled into a positioning steel ball, and the combined stud is also hollow and communicates with the accommodating space to provide a first-class road, the locking The ring fits over the connecting seat, and the inner diameter is provided with an internal thread to lock the threaded section of the connecting seat, The first steel channel is disposed in the upper half of the coupling seat from the top to the bottom, and a first flow passage hole is formed in the center of the bottom wall of the combined receiving groove. The inner diameter of the open end of the first-class hole is provided with a joint thread for the joint stud of the bottom of the joint to be locked, and the above structure is used to form a faucet outlet pipe assembly structure.

Compared with the effect of the prior art: since the connecting seat and the combined seat are screw-locked and assembled, the raft can be reliably and stably installed on the joint, and the outlet pipe is prevented from being detached from the joint, and the outlet pipe and the connection are connected. The seat is fixed by the positioning steel ball clamp, and the positioning steel ball is surely confined in the through hole through the locking ring, thereby preventing the water outlet pipe from being separated from the connecting seat, and the rotating water pipe and the connecting seat have a rotation effect, when the water outlet pipe is When the connecting seat is rotated and oscillated, not only can the lubrication degree of the rotating pipe of the water pipe be increased by positioning the steel ball, but also the strength of the structural combination can be increased, and the gap can be avoided by abrasion, thereby improving the use time limit and being practical.
