However, the existing sink is usually close to the window, and the faucet that is too high can easily interfere with people opening and closing the window, making it inconvenient for people to use. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a concealed faucet, which has the function of being easy to adjust in height and having its adjusting device hidden, thereby improving the practicality and aesthetics of the faucet.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hidden faucet, comprising a control tube, a water inlet pipe is connected to the lower end of the control tube, a transfer pipe is connected to the upper end of the control tube, a control switch is installed on the control tube, an adjusting device is connected in the transfer pipe, and a water outlet pipe is connected above the adjusting device, characterized in that: the adjusting device comprises a lifting tube located in the transfer pipe, four guide blocks are evenly distributed in the circumferential direction in the transfer pipe, a slide groove for sliding the guide block is provided on the side wall of the upgrading tube, the water outlet pipe is rotatably positioned and connected to the upper end of the lifting tube, a bellows is fixed in the lifting tube, the bellows is connected to the water outlet pipe and the water inlet pipe, a telescopic groove is provided in the guide block, a positioning block is passed through the telescopic groove, a plurality of positioning grooves are evenly distributed from top to bottom in the slide groove, and the four positioning blocks are connected to the pushing mechanism.

[0005] By adopting the above technical solution, when it is necessary to use the sink to wash pots and bowls, the positioning block is moved by the pushing mechanism so that the positioning block is separated from the positioning groove, and then the lifting tube is moved upward. When the lifting tube moves to the required height, the positioning block is pushed by the pushing mechanism to make it cooperate with the adjacent positioning groove to fix the lifting tube. In this way, the position of the water outlet pipe can be adjusted to facilitate people to wash pots and bowls; when it is not necessary to wash pots and bowls, the lifting tube can be retracted into the transfer pipe to lower the height of the entire faucet, which is convenient for operating other items near the water pipe, such as windows, making it more convenient for people to use the faucet. At the same time, people can adjust the rotation angle of the water outlet pipe according to the use scenario, so as to adjust the water outlet of the water outlet pipe to a suitable position, and the bellows and the lifting tube can be hidden in the transfer pipe, making the entire water outlet pipe more beautiful.

When the positioning block abuts against the bottom of the positioning groove, the hand-tightening bolt and the locking groove are fixed in position. The operating ring can be fixed by partially rotating the hand-tightening bolt into the locking groove, so that the position of the positioning block is fixed, thereby preventing the lifting tube from being easily moved up and down. When the lifting tube needs to be moved, the hand-tightening bolt is separated from the locking block, and then the operating ring is returned under the action of the torsion spring. At this time, the positioning block can be returned under the action of the extrusion spring and separated from the positioning groove, thereby allowing the lifting tube to move up and down.

[0010] The utility model is further configured as follows: a plurality of rotating bars are evenly distributed on the outer side wall of the operating ring.

[0011] By adopting the above technical solution, the operating ring can be more easily rotated through the rotating bar, so that the operating ring can be rotated to move the positioning block, making the positioning block and the positioning groove cooperate more easily and conveniently.

[0012] The utility model is further configured as follows: the outer side of the lifting pipe is slidably positioned up and down and connected to a limit plate, two limit blocks are evenly distributed circumferentially on the upper end of the limit plate, an auxiliary plate is fixed on the water outlet pipe, a plurality of limit holes are evenly distributed circumferentially on the upper end of the auxiliary plate, and the limit holes are gap-matched with the limit blocks.

[0013] By adopting the above technical solution, when the water outlet pipe needs to be rotated, the limit plate is moved down and positioned so that the limit block is separated from the limit hole, and the water outlet pipe can be rotated to adjust the water outlet position. When the water outlet pipe is rotated to a suitable angle, the limit plate is moved up and positioned so that the limit block cooperates with the limit hole, so that the position of the water outlet pipe can be fixed and not easily rotated.

[0014] The utility model is further configured as follows: a limit plate interactively connected to the slide slot is provided at the upper end of the lifting tube, a support plate fixed to the lifting tube is provided at the lower side of the limit plate, and the support plate and the limit plate are connected by a support spring.

[0015] By adopting the above technical solution, when the water outlet pipe needs to be rotated, the limit plate is moved downward to separate the limit block from the limit hole, so that the water outlet pipe can be rotated to adjust the water outlet position. When the water outlet pipe is adjusted to the desired position, the limit plate is loosened, so that the limit plate moves upward under the action of the supporting spring, so that the limit block cooperates with the adjacent limit hole, so that the water outlet pipe can be positioned.

[0016] In summary, the utility model has the following beneficial effects:

[0017] When there is no need to use the faucet to wash pots and bowls, the lifting tube and the bellows can be retracted into the transfer tube, so that the overall height of the faucet is lower, thereby saving faucet space and facilitating the manipulation of other items near the faucet, and the lifting tube and the bellows are retracted into the transfer tube, making the entire faucet more beautiful; when the faucet is needed to wash pots and bowls, the clamping block can be separated from the clamping slot, and the positioning block can be separated from the positioning slot to move the lifting tube up and down. When the lifting tube moves to the required height, the operating ring can be rotated to simultaneously move the four positioning blocks to cooperate with the positioning slots, and the clamping block can be matched with the clamping slot, so as to fix the height of the lifting tube and support it stably and not easy to shake.
