The large-size threaded connecting tube is used to connect the shower head, and a threaded sleeve is installed at the end of the plastic tube core and fitted onto the outside of the small-size threaded tube. A leak-proof sleeve is slidably fitted on the outside of the inner tube.
[0009] As an improvement, the front end of the leak-proof kit is provided with a threaded cylinder, which is threadedly sleeved on the outside of the shower head connection end. The bottom end of the threaded cylinder is connected to a convex sleeve that fits through a large threaded connecting pipe, a threaded sleeve, and an inner pipe.
[0010] As an improvement, a sealing gasket is installed between the bottom of the threaded cylinder and the inner wall of the convex sleeve.
[0011] As an improvement, the outer wall radius of the large-size threaded connecting pipe is the same as the outer wall radius of the threaded sleeve.
[0012] As an improvement, a limiting ring is provided between the large-size threaded connecting pipe and the small-size threaded pipe. The inner radius of the limiting ring is smaller than the inner radius of the small-size threaded pipe. A retaining ring is integrally formed at the front end of the plastic tube core. The retaining ring is located inside the large-size threaded connecting pipe.
[0013] As an improvement, the retaining ring and the limiting ring are connected by adhesive sealing.
[0014] III. Beneficial Effects
[0015] The advantages of this utility model compared with the prior art are as follows: the inner pipe is connected to the shower head by an external threaded connector consisting of a large threaded connecting pipe and a small threaded pipe, and the inner pipe is fixedly installed inside the large threaded connecting pipe, so the connection is firm and will not loosen when the shower head pulls the inner pipe and the external threaded connector.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, a metal pull-out shower head connection device includes an inner tube 1 and an external threaded connector. A plastic core 2 passes through the inner tube 1. The external threaded connector is composed of a large threaded connecting tube 3 and a small threaded tube 4 connected together. The large threaded connecting tube 3 is used to connect the shower head. A threaded sleeve 7 is installed at the end of the plastic core 2 and is fitted onto the outside of the small threaded tube 4. A leak-proof sleeve 8 is slidably fitted on the outside of the inner tube 1.
[0025] With the above structure, the threaded sleeve 7 is threaded onto the outside of the small threaded tube 4, connecting the inner tube 1 to one end of the external threaded connector. The leak-proof kit 8 protects the connection between the small threaded tube 4 and the threaded sleeve 7 to prevent leakage. The specific structure is as follows:
[0026] As attached Figure 3 and attached Figure 4 As shown, a limiting ring 5 is provided between the large threaded connecting pipe 3 and the small threaded pipe 4. The inner radius of the limiting ring 5 is smaller than the inner radius of the small threaded pipe 4. A retaining ring 6 is integrally formed at the front end of the plastic tube core 2. The retaining ring 6 is located inside the large threaded connecting pipe 3. The retaining ring 6 and the limiting ring 5 are connected by adhesive sealing.
[0027] With the above structure, one end of the plastic core 2 passes through the large threaded connecting tube 3 and the small threaded tube 4. The retaining ring 6 is located inside the large threaded connecting tube 3. The retaining ring 6 is limited by the limiting ring 5. The retaining ring 6 and the limiting ring 5 are connected by adhesive sealing, and the plastic core 2 is fixedly installed inside the external thread connector. It will not fall off when pulled.
[0028] Combined with appendix Figure 2 Appendix Figure 5 and attached Figure 6As shown, the front end of the leak-proof kit 8 is provided with a threaded cylinder 9. The threaded cylinder 9 is threadedly sleeved on the outside of the shower head connection end. The bottom end of the threaded cylinder 9 is connected to a convex sleeve 10 through which the large threaded connecting pipe 3, the threaded sleeve 7 and the inner pipe 1 pass. A sealing gasket 11 is installed between the bottom of the threaded cylinder 9 and the inner wall of the convex sleeve 10. The outer radius of the large threaded connecting pipe 3 is the same as the outer radius of the threaded sleeve 7. After the threaded sleeve 7 is sleeved on the outside of the small threaded pipe 4, its outer wall is on the same curved surface as the large threaded connecting pipe 3, and can fit with the sealing gasket 11.
[0029] With the above structure, after the threaded sleeve 7 is fitted onto the outside of the small threaded pipe 4, the leak-proof kit 8 is moved to the front end of the inner pipe 1. The threaded sleeve 7 and the large threaded connecting pipe 3 are placed in the convex sleeve 10. The outer wall of the threaded sleeve 7 and the large threaded connecting pipe 3 is tightly wrapped by the sealing gasket 11 to prevent water leakage. The threaded cylinder 9 is fitted onto the outside of the large threaded connecting pipe 3. By rotating the leak-proof kit 8, the shower head connection end on the outside of the large threaded connecting pipe 3 is threaded and installed on the threaded cylinder 9, thus completing the stable connection and leak prevention between the inner pipe 1 and the external threaded connector.
