Description

Technical Field

[0001] The present invention relates to the technical field of faucets, and in particular to a pull-out faucet. Background Art

[0002] Existing pull-out faucets usually adopt a pull-out tube structure. The user can pull out the head of the pull-out faucet together with the water pipe to facilitate the adjustment of the water outlet direction. It is flexible and convenient, and can easily clean sinks, countertops and other places. At the same time, the pull-out tube can be reset under the action of its own weight after the user has finished use, or a heavy hammer (counterweight block) can be installed at the tail end of the pull-out tube to assist its reset.

[0003] However, the head water outlet assembly of the existing pull-out faucet cannot hover after being pulled out, that is, the user needs to overcome the weight of the pull-out tube and the heavy hammer when using the pull-out tube, and continuously apply pulling force to the pull-out tube, which can easily cause arm fatigue in the user after long-term use. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a pull-out faucet to solve the above-mentioned problem.

[0029] Example

[0030] Combination Figures 1 to 6 As shown, this embodiment provides a pull-out faucet, including a pull-out tube 6, a guide tube 5, and a positioning member 8 rotatably arranged on the pull-out tube;

[0031] The inner wall of the guide tube 5 is provided with a curved track guide groove, and a positioning point 16 is provided on the track guide groove;

[0032] The positioning member 8 is configured as follows: when the pull-out tube 6 is pulled out, it can move upward along the track guide groove, and when the pull-out tube 6 is retracted, it can hover on the nearest positioning point 16 so that the pull-out tube 6 will not continue to retract; when the pull-out tube 6 is pulled out again, it can move upward along the track guide groove again, and can retract the pull-out tube 6 to its initial position.

[0033] Through the track guide groove on the inner wall of the guide tube 5 and the setting of the positioning point 16, the positioning member 8 can move upward along the track guide groove when the pull-out tube 6 is pulled out, and can hover on the nearest positioning point 16 when the pull-out tube 6 retreats, so that the pull-out tube 6 will not continue to retreat; when the pull-out tube 6 is pulled out again, it can move upward along the track guide groove again, and can retreat to the initial position. In this way, the pull-out tube 6 can hover at a certain position when it is pulled out, so that the user does not need to continuously apply pulling force to the pull-out tube 6 during use, avoiding the user's arm fatigue caused by long-term use.

[0034] Specifically, in this embodiment, the pull-out faucet includes a body 1, a water outlet elbow 2 connected to the body 1, a valve core provided on the body 1, and an operating handle 3 for controlling the valve core. The pull-out pipe 6 is placed in the body 1 and the water outlet elbow 2, and one end of the pull-out pipe 6 is connected to a water outlet nozzle 11. The pull-out pipe 6 is connected to a sleeve 4, and the sleeve 4 fixes the body 1 on the table through a fixing seat 12 and a nut.

[0035] In this embodiment, the guide tube 5 is disposed in the sleeve 4. Specifically, Figure 5 As shown, the guide tube 5 includes a first semi-ring guide tube and a second semi-ring guide tube provided with the first trajectory guide groove 13 and the second trajectory guide groove 14; and the trajectory guide groove on the first semi-ring guide tube is symmetrically arranged with the trajectory guide groove on the second semi-ring guide tube. Figure 4 As shown, the positioning member 8 is a swivel 9 rotatably connected to the drawing tube 6, and the side of the swivel 9 is provided with a boss 10 that can move in the track guide groove and hover on the positioning point 16. It should be noted that the first half-ring guide tube and the second half-ring guide tube have the same structure.

[0036] In this embodiment, the lower entrance openings of the first track guide groove 13 and the second track guide groove 14 are connected to form a trumpet-shaped entrance opening 20, and a first guide portion 21 is provided, which is used to enable the boss 10 to move upward along the first track guide groove 13 after entering the entrance opening 20. The trumpet-shaped entrance opening 20 can enable the boss 10 to enter the track guide groove more smoothly during the upward movement.

[0037] In this embodiment, a plurality of positioning islands 15 are arranged at intervals along the axial direction of the guide sleeve between the first track guide groove 13 and the second track guide groove 14, and a groove is arranged at the upper end of the positioning island 15 to form the positioning point 16. A second guide portion 17 is arranged at the lower end of the positioning island 15, and the second guide portion 17 includes a first guide edge 18 placed on one side of the first track guide groove 13 and a second guide edge 19 placed on one side of the second track guide groove 14; and the bottom end of the second guide portion 17 of the last positioning island 15 is located above the lowest point of the groove of the next positioning island 15 close to the first track guide groove 13, so that the lowest point of the groove is placed below the second guide edge 19. A counterweight block 7 is arranged below the pull-out tube 6 to facilitate the rapid retraction of the pull-out tube 6. In this way, when the pull-out tube 6 is pulled out, it can move upward along the first track guide groove 13, and under the action of the counterweight block 7, the boss 10 can fall and hover on the groove under the guidance of the first guide edge 18; and when the pull-out tube 6 is pulled out again, the boss 10 enters the second track guide groove 14 and moves upward under the guidance of the second guide edge 19, and can move along the second track guide groove 14 under the action of the counterweight block 7 and fall back to the initial position. And the upper end of the topmost positioning island 15 forms the closed end of the second track guide groove 14, so that when the pull-out tube 6 is pulled out again, the boss 10 will not be separated from the second track guide groove 14, so as to ensure that the boss 10 can fall back to the initial position along the second track guide groove 14. The arrangement of multiple positioning islands 15 in this way realizes that the pull-out tube 6 has multiple hovering gears.

[0038] In this embodiment, the first half-ring guide tube and the second half-ring guide tube are injection molded by plastic material. Of course, in other embodiments, the guide tube 5 and the sleeve 4 can also be integrated, and the first track guide groove 13 and the second track guide groove 14 are directly arranged in the sleeve 4. Since the sleeve 4 is usually made of metal, it can be divided into two parts along its axis and then welded after being molded separately, which will not be elaborated in detail.

[0039] In other embodiments, Figure 6 As shown, a positioning island 15 is provided between the first trajectory guide groove 13 and the second trajectory guide groove 14, and a second guide portion 17 is provided above the positioning point 16, and the upper end of the second guide portion 17 forms the closed end of the second trajectory guide groove 14. The guide pipe 5 is provided in the shaft sleeve 22 of the water outlet elbow 2 connected to the faucet body 1. This method realizes the single-gear suspension of the pull-out pipe 6.

[0040] Of course, the upper end of the first trajectory guide groove 13 can also form a trumpet-shaped opening, so that when the pulling tube 6 is pulled out longer and the boss 10 is separated from the first trajectory guide groove 13, it can fall more smoothly under the action of the counterweight block 7 and re-enter the first trajectory guide groove 13, and hover on the positioning point 16.
