[0005] In the above-mentioned pull-out tube assembly, the anti-wear unit is a hollow connecting sleeve, and a convex shaft portion axially protruding outward is arranged on the end face of the connecting sleeve connected to the pull-out body. A recessed groove axially recessed inwardly for easy connection with the pull-out body is provided on the end face of the convex shaft portion. The convex shaft portion is divided into an outer shell and an inner shell through the recessed groove, and a hook portion is arranged on the outer peripheral wall of the inner shell to form a snap-fit ​​with the pull-out body.

[0006] In the above-mentioned pull-out tube assembly, the stabilizing unit is a stabilizing sleeve, which is arranged on the connecting sleeve. The inner wall of the stabilizing sleeve located at the upper end opening is provided with a convex ring portion which protrudes radially inward and forms a snap fit with the above-mentioned connecting sleeve. The outer wall of the connecting sleeve is provided with an outer convex ring which protrudes radially outward and contacts with the convex ring portion. The outer convex ring is used to leave a distance between the inner wall of the stabilizing sleeve and the outer wall of the connecting sleeve. Threads are provided on the inner and outer peripheral walls of the stabilizing sleeve.

[0007] In the above-mentioned pull-out tube assembly, a plurality of recessed grooves are provided on the outer peripheral wall of the connecting sleeve located at the stabilizing sleeve along the length direction thereof.

[0008] Compared with the prior art, the pull-out tube assembly has the following advantages:

[0009] 1. The front end of the pull-out body is provided with an anti-wear unit which is connected to it, reduces collision wear, and can be connected to other pipe structures. The pipe structure can be a water distribution pipe or a filter head. The anti-wear unit is provided with a stabilizing unit which is connected to it, has a limiting function, and improves the connection stability. The arrangement of the above structure has the advantages of easy disassembly and reduced replacement cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 As shown, the pull-out tube assembly includes a pull-out body 1, one end of which is connected to the faucet body and the other end of which extends out of the faucet body. A wear-resistant unit is arranged on the front end of the pull-out body 1, which is connected to the pull-out body 1, reduces collision wear, and can be connected to other pipe structures. The pipe structure can be a water distribution pipe or a filter head. The wear-resistant unit is arranged on the wear-resistant unit, which is connected to the pull-out body 1, has a limiting function, and improves the connection stability. The wear-resistant unit is a hollow connecting sleeve 2, and an axially outwardly protruding convex shaft portion 3 is arranged on the end surface of the connecting sleeve 2 connected to the pull-out body 1. A recessed groove is arranged on the end surface of the recessed shaft portion 3, which is axially inwardly recessed and convenient for connection with the pull-out body 1. The recessed groove divides the convex shaft portion 3 into an outer shell and an inner shell. The outer circumferential wall of the inner shell is provided with several layers of hook parts 4 arranged along its length direction and forming a snap fit with the pull-out body 1. The end face of the outer shell is provided with an extension part connected to it and fitted with the outer wall of the pull-out body 1, and the connection between the extension part and the outer shell is provided with a chamfer. The stabilizing unit is a stabilizing sleeve 5, which is sleeved on the connecting sleeve 2. The inner wall of the stabilizing sleeve 5 located at the upper end opening is provided with a convex ring part 6 that protrudes radially inward and forms a snap fit with the above-mentioned connecting sleeve 2. The outer wall of the connecting sleeve 2 is provided with an outer convex ring 7 that protrudes radially outward and conflicts with the convex ring part 6. The outer convex ring 7 is used to leave a distance between the inner wall of the stabilizing sleeve 5 and the outer wall of the connecting sleeve 2, and the inner and outer circumferential walls of the stabilizing sleeve 5 are provided with threads.

[0014] As a preferred structure, a plurality of recessed grooves are provided on the outer peripheral wall of the connecting sleeve 2 at the stabilizing sleeve 5 along the length direction thereof, and a sealing ring can be provided at the recessed groove of the connecting sleeve 2 to enhance the sealing performance.

[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0016] Although the terms such as the drawer body 1, the connecting sleeve 2, the convex shaft portion 3, the hook portion 4, the stabilizing sleeve 5, the convex ring portion 6, and the outer convex ring 7 are frequently used in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional limitation is contrary to the spirit of the utility model.
