Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a water outlet for a rotary faucet. Background Technology

[0002] A rotary faucet generally consists of a faucet body, a rotary joint mounted on the outlet pipe of the faucet body, and a water outlet connected to the rotary joint. Therefore, the outer diameter of the water outlet must match the outer diameter of the faucet body, and the inner diameter must match the rotary joint. Currently, the water outlet is generally manufactured by welding a concave pipe fitting onto it. However, producing the water outlet by welding fixes the production material, increases production costs, and the welding yield cannot be guaranteed. Leakage testing is also required, leading to excessively high production costs for the water outlet and ultimately affecting overall economic efficiency. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a water outlet for a rotating faucet.

[0004] To achieve the above objectives, the technical solution of this utility model is to provide a water outlet for a rotary faucet, comprising: a protective shell matching the outer diameter of the faucet, the protective shell having a slot, and a rotary tube for connecting to a rotary joint being provided on the protective shell via a positioning device; The rotating tube includes: a connecting tube that matches the rotating joint, and the connecting tube is provided with an extension tube that communicates with the connecting tube; The extension tube is provided with a water outlet, and the protective shell is provided with a water outlet hole corresponding to the water outlet.

[0005] A further improvement is that the positioning device includes: at least one threaded seat inside the protective shell, a connecting seat corresponding to the threaded seat on the extension tube, and a connecting groove corresponding to the hole position of the threaded seat on the connecting seat.

[0006] A further improvement is that: the bottom of the protective shell is provided with a locking groove, the locking groove is provided with a locking ring that engages with the protective shell, the bottom of the connecting pipe is provided with an installation ring, the locking ring is provided with several through holes, the installation ring is provided with threaded holes corresponding to the through holes, and the through holes are also provided with countersunk holes.

[0007] A further improvement is that the locking ring is also provided with a stabilizing block that abuts against the connecting pipe.

[0008] A further improvement is that a cover plate is provided on the slot.

[0009] A further improvement is that the slot is also provided with a recessed groove that matches the cover plate, and the cover plate is located on the recessed groove.

[0010] A further improvement is that a stable positioning block that abuts against the inner wall of the protective shell is provided on the extension pipe at the water outlet.

[0011] A further improvement is that the rotating tube is provided with a first core-pulling hole corresponding to the extension tube at one end of the connecting tube. A plug is provided in the first core-pulling hole, and a limiting block is provided on the plug. One end of the limiting block abuts against the protective shell and the other end abuts against the rotating tube.

[0012] A further improvement is that a support block can be provided on the connecting pipe at the position of the first core-pulling hole.

[0013] A further improvement is that the rotating tube has a second core-pulling hole corresponding to the extension tube at one end of the outlet.

[0014] The advantages and beneficial effects of this utility model are as follows: With low production costs and high structural strength, the water outlet is manufactured by combining a rotating tube with a protective shell. This means that the material of the water outlet is no longer limited to metal, greatly improving production convenience. It also allows both the rotating tube and the protective shell to be made of plastic, significantly reducing material costs and thus lowering the overall production cost of the faucet.
