Description

Technical Field

[0001] The utility model relates to the field of faucets, and particularly to a leak-proof faucet. Background Art

[0002] A faucet is a common name for a water valve, which is used to control the size of the water flow switch and has the effect of saving water. The main body of the current faucet is usually composed of a metal shell and a plastic inner core. The valve core is installed on the inner core. Water flows into the inner core, is mixed by the valve core and then flows out from the outlet pipe of the shell. The inner core and the shell are sealed by a sealing ring. Since the side wall of the inner core is relatively thin, the sealing ring is installed between the side wall and the shell and is sealed by the extrusion between the side wall and the shell. Therefore, the problem of water leakage caused by the deformation of the side wall is likely to occur.

[0003] In view of this, the inventor of the present case has conducted in-depth research on the above-mentioned defects in the prior art, and thus this case has been developed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a leak-proof faucet, which has the advantages of preventing water leakage and good stability.

[0005] In order to achieve the above object, the solution of the utility model is:

[0006] A leak-proof faucet, which includes a shell and an inner core. The shell forms a cavity that is communicated at the upper and lower ends. The side wall of the shell forms an outlet pipe. The upper end of the inner core forms a side plate. The side plate and the inner wall of the shell enclose a water passage. The water passage is communicated with the outlet pipe and the water outlet of the inner core. A sealing ring is installed on the water passage. The sealing ring is installed between the side plate and the shell. The upper end of the shell forms a limiting groove, and the upper end of the side plate forms a limiting head. The limiting head abuts and is clamped in the limiting groove.

[0007] Further, the limiting groove is an inclined groove, the limiting head is an inclined block, and the inclined block is inserted and abuts in the inclined groove.

[0008] Further, the limiting groove is a flat-bottomed groove, the limiting head is a flat-topped convex head, and the convex head is inserted and abuts in the groove.

[0009] Further, a limiting strip is further formed on the upper part of the shell, and the limiting strip abuts against the side surface of the side plate.

[0010] Further, the side plate encloses a valve core cavity, and a valve core is installed in the valve core cavity.

[0011] Further, a positioning groove is further formed on the side plate, and a positioning strip is formed on the upper part of the shell. The positioning strip is inserted into the positioning groove.

[0012] Furthermore, the housing is made of metal material, and the inner core is made of plastic material.

[0013] Furthermore, an installation thread is formed at the upper end of the housing.

[0014] Furthermore, a sealing groove is also formed on the side plate, and the sealing ring is installed in the sealing groove.

[0015] After adopting the above structure, a leak-proof faucet involved in the present utility model has at least the following beneficial effects:

[0016] First, by inserting and abutting the limiting head against the limiting groove, support can be provided for the upper end of the side plate. In this way, when the sealing ring abuts between the side plate and the housing, the side plate is not easily deflected and deformed inward, which makes the sealing ring installed more tightly, avoids water leakage problems, and greatly improves the stability of the faucet.

[0017] Second, by abutting the limiting strip against the side plate, the support strength of the side plate can be improved, and the stability of the faucet can be further improved. And the limiting strip can also provide a positioning function when installing the inner core, which is convenient for docking the water passing channel and the water outlet pipe.

[0018] Third, by inserting and connecting the positioning groove and the positioning strip, the rotation of the inner core can be restricted when installing the inner core, which is convenient for docking the water passing channel and the water outlet pipe.

[0019] Compared with the prior art, the leak-proof faucet of the present utility model can improve the sealing effect of the faucet, avoid water leakage of the faucet, and greatly improve the stability of the faucet. Description of the Drawings

[0031] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0032] As Figures 1 to 5 shown, it is a leak-proof faucet related to the present invention, including a housing 1 and an inner core 2. The housing 1 forms a cavity 11 that is communicated at both the upper and lower ends. A water outlet pipe 12 is formed on the side wall of the housing 1. The upper end of the inner core 2 forms a side plate 21. The side plate 21 and the inner wall of the housing 1 enclose a water passage 22. The water passage 22 is communicated with the water outlet pipe 12, and the water passage 22 is communicated with the water outlet 27 of the inner core 2. A sealing ring 3 is installed on the water passage 22. The sealing ring 3 is installed between the side plate 21 and the housing 1. A limit groove 13 is formed at the upper end of the housing 1. A limit head 23 is formed at the upper end of the side plate 21. The limit head 23 is abutted and clamped in the limit groove 13. By inserting and abutting the limit head 23 against the limit groove 13, support can be provided for the upper end of the side plate 21. In this way, when the sealing ring 3 abuts between the side plate 21 and the housing 1, the side plate 21 is not easily deflected and deformed inward, which makes the sealing ring 3 installed more tightly, avoids water leakage problems, and greatly improves the stability of the faucet.

[0033] Preferably, as Figure 1 , Figure 2 and Figure 5 shown, the limit groove 13 is an inclined groove, and the limit head 23 is an inclined block. The inclined block is inserted and abutted in the inclined groove.

[0034] Preferably, as Figure 3 and Figure 4 shown, the limit groove 13 is a flat-bottomed groove, and the limit head 23 is a flat-topped convex head. The convex head is inserted and abutted in the groove.

[0035] Preferably, as Figure 1 and Figure 2As shown, a limiting strip 14 is further formed on the upper part of the housing 1, and the limiting strip 14 abuts against the side surface of the side plate 21. By abutting the limiting strip 14 against the side plate 21, the support strength of the side plate 21 can be improved, and the stability of the faucet can be further improved. And the limiting strip 14 can also provide a positioning function when installing the inner core 2, facilitating the docking of the water passage 22 and the water outlet pipe 12.

[0036] Preferably, the side plate 21 encloses a valve core cavity 24, and a valve core is installed in the valve core cavity 24. The valve core is installed on the inner core 2, and its periphery is wrapped by the side plate 21. Water flows into the inner core 2, is mixed by the valve core and then flows from the water outlet 27 into the water passage 22, and then flows from the water passage 22 to the water outlet pipe 12.

[0037] Preferably, a positioning groove 25 is further formed on the side plate 21, and a positioning strip 15 is formed on the upper part of the housing 1. The positioning strip 15 is inserted into the positioning groove 25. By the insertion of the positioning groove 25 and the positioning strip 15, the rotation of the inner core 2 can be restricted when installing the inner core 2, facilitating the docking of the water passage 22 and the water outlet pipe 12.

[0038] Preferably, the housing 1 is made of metal material, and the inner core 2 is made of plastic material. Therefore, compared with an integrally formed metal body, the split plastic inner core 2 has better economy.

[0039] Preferably, an installation thread 16 is formed at the upper end of the housing 1. Through the installation thread 16, the valve core can be installed on the inner core 2 with a gland.

[0040] Preferably, a sealing groove 26 is further formed on the side plate 21, and the sealing ring 3 is installed in the sealing groove 26. In this way, both sides of the sealing ring 3 abut against the side plate 21 and the housing 1 respectively, thereby sealing the water passage 22.
