Description

Technical Field

[0001] The utility model relates to the technical field of building sanitary ware devices, in particular to a quick installation structure of a liftable pull-out faucet. Background Art

[0002] The liftable pull-out faucet currently on the market generally has a thread machined at the connection between the main body and the lift joint straight pipe, and then a guide threaded tube is placed inside the main body, and the threaded connection is combined into a liftable pull-out faucet structure with the assistance of a swivel sleeve, a retaining ring and other parts. The entire liftable pull-out faucet requires many parts, the assembly process is difficult, and the cost is relatively high. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the prior art and to provide a quick installation structure of a liftable pull-out faucet, which has a simple and reliable structure, meets the functional requirements of liftability, uses fewer parts, is quick and convenient to install, is suitable for mass manufacturing, reduces costs and improves efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A quick installation structure of a liftable pull-out faucet comprises a shower head, a valve body assembly, a lifting joint, a limit sleeve and a shower hose, wherein a guide hole tube is arranged inside the valve body assembly, and a limit groove is arranged on the inner wall of the guide hole tube, the outer diameter of the limit sleeve matches the inner diameter of the guide hole tube, and a plurality of circumferentially distributed inwardly retracted undercuts are arranged thereon, the upper end of the lifting joint is connected to the rear end of the shower head, and a straight pipe is arranged at the lower part, and the outer diameter of the straight pipe matches the inner diameter of the limit sleeve, the upper end of the shower hose is connected to the water inlet end of the shower head, and passes through the lifting joint and the valve body assembly. During assembly, place the limit sleeve into the guide hole tube at the upper end of the valve body assembly, and then insert the straight tube of the lifting joint. When the straight tube is inserted into the limit sleeve, the inward buckle of the limit sleeve will be squeezed outward due to the action of the straight tube, thereby fixing the limit sleeve on the valve body assembly. Connect the lower end of the shower hose to the hot and cold water outlet pipes, and the water flows directly to the shower head along the shower hose. The straight tube can move up and down along the inner hole of the limit sleeve. The shower head or the upper part of the lifting joint can be lifted and lowered by holding it.

[0006] Preferably, a sink is provided on the valve body assembly at the top of the guide hole tube, and a corresponding boss is provided on the top of the limiting sleeve. After assembly, the boss falls into the sink, thereby playing the role of axial limiting of the limiting sleeve.

[0007] Preferably, the bottom outer wall of the straight pipe is provided with an O-ring groove, in which an O-ring is provided. The shower head moves up and down with the lifting joint, and when the lifting joint rises to the highest point, it will be blocked by the O-ring and cannot continue to rise, thereby achieving a limiting effect.

[0008] Preferably, a threaded tail pipe is provided at the bottom end of the valve body assembly for installation and fixation of the valve body assembly.

[0009] Preferably, a switch valve is provided on one side of the valve body assembly to control the water output from the faucet and the hotness or coldness of the water.

[0010] Preferably, the upper portion of the lifting joint is a curved structure to provide a transition for the angle change between the shower head and the valve body assembly.

[0011] The advantages of the utility model are: the utility model has a simple and reliable structure, meets the functional requirements of being able to be lifted and lowered, uses fewer parts, is quick and convenient to install, is suitable for batch manufacturing and production, reduces costs and improves efficiency.

[0028] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0029] Embodiment 1: Figure 1-2 As shown, a quick installation structure of a liftable pull-out faucet includes a shower head 10, a valve body assembly 20, a lift joint 30, a limit sleeve 40 and a shower hose 50.

[0030] Combination Figure 3 As shown, a guide hole pipe 21 is provided inside the valve body assembly 20, and a limit groove 22 is provided on the inner wall of the guide hole pipe 21. A switch valve is provided on one side of the valve body assembly 20.

[0031] Combination Figure 4-5 As shown, the outer diameter of the limiting sleeve 40 matches the inner diameter of the guide tube 21, and is provided with a plurality of circumferentially distributed inwardly recessed buckles 41.

[0032] Combination Figure 6 As shown, the upper end of the lifting joint 30 is connected to the rear end of the shower head 10 , the upper part thereof is a curved structure, and the lower part is provided with a straight pipe 31 , the outer diameter of the straight pipe 31 matches the inner diameter of the limiting sleeve 40 .

[0033] Combination Figure 7-8 As shown, the upper end of the shower hose 50 is connected to the water inlet end of the shower head 10, passes through the lifting joint 30 and the valve body assembly 20, and the lower end is connected to the hot and cold water outlet pipes.

[0034] In addition, combined Figure 1-2 As shown, a threaded tail pipe 70 is disposed at the bottom end of the valve body assembly 20 .

[0035] Embodiment 2: Figure 3-5 and Fig. 9 As shown, on the basis of the first embodiment, a sink 23 is provided on the valve body assembly 20 at the top of the guide hole tube 21 , and a corresponding boss 42 is provided on the top of the limit sleeve 40 .
