Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a pull-out faucet that can be raised and lowered. Background Technology

[0002] Pull-out faucets are frequently used bathroom products in people's lives. As people's living standards improve, the functions of pull-out faucets have become increasingly diverse and sophisticated. However, traditional pull-out faucets cannot be raised or lowered, occupying a significant amount of space when not in use, wasting space resources. They are also easily touched, making them inconvenient to use and resulting in a poor user experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a simple, easy-to-use, liftable pull-out faucet.

[0004] This utility model is achieved through the following technical solution:

[0005] A liftable pull-out faucet includes a threaded tube and a water outlet bend. The water outlet bend is fitted inside the threaded tube. A first O-ring is fitted on the outer side of the bottom of the water outlet bend. A first retaining ring is installed on the inner side of the lower part of the threaded tube. A second retaining ring is fitted on the outer side of the bottom of the water outlet bend. The first retaining ring is locked between the first O-ring and the second retaining ring.

[0006] Furthermore, a guide slope is provided on the inner side of the lower part of the dental tube.

[0007] Furthermore, a first buffer rubber ring is provided on the top of the first retaining ring.

[0008] Furthermore, a wear-resistant ring is installed on the inner side of the top of the dental tube, and a second buffer rubber ring is provided at the bottom of the wear-resistant ring.

[0009] Furthermore, a pull-out head is installed at the end of the water outlet bend.

[0010] Furthermore, a plastic sheath is installed at the bottom of the water outlet bend.

[0011] Furthermore, the bottom of the water outlet bend is provided with a connector for installing the first O-ring and the second retaining ring.

[0012] Furthermore, a mounting base is screwed to the outer side of the top of the dental tube, and a second O-ring is installed at the bottom of the mounting base.

[0013] Furthermore, a protective tube is installed at the bottom of the dental tube.

[0014] Furthermore, a mounting nut is screwed onto the outer side of the tooth tube, and a plastic washer and a metal washer are sequentially fitted onto the outer side of the tooth tube from top to bottom. A locking screw that abuts against the metal washer is screwed onto the mounting nut.

[0015] Compared to existing technologies, this utility model features a water outlet bend fitted inside the dental tube. A first O-ring is fitted on the outer side of the bottom of the water outlet bend, a first retaining ring is installed on the inner side of the lower part of the dental tube, and a second retaining ring is fitted on the outer side of the bottom of the water outlet bend. The first retaining ring is locked between the first O-ring and the second retaining ring, allowing the pull-out faucet to rise and fall. The first retaining ring supports the first O-ring to prevent the water outlet bend from descending, and the second retaining ring limits the upward pull of the water outlet bend. When not in use, the water outlet bend can be pressed down, and most of the water outlet bend is retracted under the countertop, occupying little space on the countertop, saving space resources, and is not easily touched, making it convenient to use and providing a better user experience.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 The present invention discloses a pull-out faucet with adjustable height, comprising a threaded tube 1 and a water outlet bend 2. The water outlet bend 2 is fitted inside the threaded tube 1. A first O-ring 3 is fitted on the outer side of the bottom of the water outlet bend 2. A first retaining ring 4 is installed on the inner side of the lower part of the threaded tube 1. A second retaining ring 5 is fitted on the outer side of the bottom of the water outlet bend 2. The first retaining ring 4 is locked between the first O-ring 3 and the second retaining ring 5. The pull-out faucet of this invention can be raised and lowered. The first retaining ring 4 supports the first O-ring 3 to prevent the water outlet bend 2 from descending. The second retaining ring 5 limits the upward pull of the water outlet bend 2. When not in use, the water outlet bend 2 can be pressed down, and most of the water outlet bend 2 is retracted under the countertop, occupying little space on the countertop, saving space resources, and is not easily touched, making it convenient to use and providing a good user experience.

[0023] A guide slope 6 is provided on the inner side of the lower part of the dental tube 1, which facilitates the smooth insertion of the first O-ring 3 and the second retainer 5 into the dental tube 1, and makes the upward pulling smoother and more stable.

[0024] The top of the first retaining ring 4 is provided with a first buffer rubber ring 7, which helps to buffer the force when the water outlet bend 2 is pressed down, and avoids damage to the first O-ring 3.

[0025] As a specific implementation method, the first retaining ring 4 is an open retaining ring, which improves the performance.

[0026] A wear-resistant ring 8 is installed on the inner side of the top of the toothed tube 1. A second buffer rubber ring 9 is provided at the bottom of the wear-resistant ring 8, which makes the water outlet bend 2 rotate more smoothly, stably and durable.

[0027] A pull-out head 10 is installed at the end of the water outlet bend 2. The end of the water outlet bend 2 is provided with an installation sleeve for the pull-out head 10 to be installed. The pull-out head 10 is connected to the pull-out pipe.

[0028] A plastic sleeve 11 is installed at the bottom of the outlet bend 2 to prevent the pull tube from contacting the bottom of the outlet bend 2 and damaging the pull tube.

[0029] The bottom of the water outlet bend 2 is provided with a connector 12 for installing the first O-ring 3 and the second retaining ring 4. The connector 12 is provided with a groove for installing the first O-ring 3 and the second retaining ring 4, making the installation of the first O-ring 3 and the second retaining ring 4 more stable.

[0030] A mounting base 13 is screwed onto the outer side of the top of the tooth tube 1 to facilitate the stable installation of the pull-out faucet. A second O-ring 14 is installed at the bottom of the mounting base 13 to make the installation of the pull-out faucet more stable.

[0031] A protective tube 15 is installed at the bottom of the tooth tube 1 to protect the pull tube, prevent the pull tube from getting tangled, and facilitate the installation of the return spring on the outside of the pull tube.

[0032] A mounting nut 16 is screwed onto the outside of the threaded tube 1. A plastic washer 17 and a metal washer 18 are sequentially fitted onto the outside of the threaded tube 1 from top to bottom. A locking screw 19 is screwed onto the mounting nut 16 to abut against the metal washer 18, making the installation of the pull-out faucet easy and secure.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
