Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bathroom, specifically relates to a water stop pipe fitting. BACKGROUND

[0002] When the angle valve is replaced, the water total valve needs to be closed, and after replacement is finished, the water total valve is opened again. The angle valve is used at a distance from the water total valve, and it is troublesome to operate the water total valve back and forth.

[0003] The water stop valve installed in two parts on the market is externally connected to the installation interface or occupies the thread in the installation interface, and needs to be separately installed in the installed pipe fitting, which is not convenient and also occupies the internal thread in the original installation interface. In view of this, the inventor of the present application has conducted in-depth research on the above-mentioned defects in the prior art, and thus the present case is produced. SUMMARY

[0004] The main purpose of the utility model is to provide a water stop pipe fitting, which can replace the angle valve without returning to close the water total valve, and also saves the trouble of separate installation later, and can reserve sufficient thread depth for thread connection of the angle valve and faucet.

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

[0006] A water stop pipe fitting, comprising a pipe fitting, a water stop valve is arranged in the opening of the pipe fitting; the water stop valve comprises a shell and a movable rod, a threaded seat is integrally formed on the shell, an internal thread is arranged in the threaded seat, the outer wall of the threaded seat has a slip-resistant and pull-resistant structure connected with the pipe fitting, and the threaded seat and the pipe fitting are integrally injection molded.

[0007] Further, the internal thread is G1 / 2 or G3 / 4 thread.

[0008] Further, the slip-resistant and pull-resistant structure comprises an annular groove on the outer sidewall of the threaded seat, and further comprises a protrusion distributed along the annular interval at the bottom of the threaded seat.

[0009] Further, the pipe fitting is a straight pipe fitting, an L-shaped pipe fitting or a T-shaped pipe fitting, and the water stop valve is arranged on the interface for outward water outlet.

[0010] Further, the internal thread extends to the edge of the inner cavity bottom surface of the threaded seat.

[0011] Further, a rubber pad is arranged on the movable rod in the inner cavity of the threaded seat, and the diameter of the rubber pad is smaller than the small diameter of the internal thread.

[0012] Further, the movable rod is provided with a water-stopping part made of rubber; one end of the shell is provided with a water inlet, and when the movable rod is in the water-stopping position, the water-stopping part blocks the water inlet; the water-stopping part is provided with a water-blocking conical surface at one end facing the water inlet, and is provided with a giving conical surface at one end away from the water inlet.

[0013] With the above structure, the water-stopping pipe fitting has at least the following beneficial effects:

[0014] I. The threaded seat is integrally arranged on the shell, and the threaded seat is integrally connected with the pipe fitting to install the angle valve and the faucet. Since the threaded seat is specially arranged on the shell, the length of the thread in the threaded seat can be longer than that of the internal thread in the traditional installation interface, so that the faucet or the angle valve has sufficient thread depth during installation. The anti-slip and anti-pull structure makes the threaded seat and the pipe fitting more firmly connected.

[0015] II. The shape of the pipe fitting can be a straight pipe fitting, an L-shaped pipe fitting or a T-shaped pipe fitting to meet different use requirements.

[0016] III. After the angle valve is installed in the pipe fitting, the movable rod is pushed inward, so that the water passage is opened and the water flows to the angle valve. After the angle valve is removed, the movable rod moves outward, so that the water passage is closed. The arrangement of the water-blocking conical surface enables the water-stopping part to fully block the water inlet, and also guides the water flow when the water passage is opened. The giving conical surface has the function of guiding the water flow, and for the L-shaped and T-shaped pipe fittings, the giving conical surface can also reduce the interference between the water-stopping part and the inner wall of the curved pipe fitting.

[0017] Compared with the prior art, the water-stopping valve is provided with a threaded seat, and the threaded seat is integrally connected with the pipe fitting through the anti-slip and anti-pull structure, so that the structure is stable. After the angle valve or the faucet is removed, the water-stopping valve can automatically stop water, avoiding the trouble of repeatedly closing the water valve. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0030] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0031] like Figures 1 to 10 As shown, this utility model relates to a water-stopping pipe fitting, comprising a pipe fitting 1, with a water-stopping valve 2 disposed within the opening of the pipe fitting 1; the water-stopping valve 2 includes a housing 21 and a movable rod 3, the housing 21 having an integrally formed threaded seat 22, the threaded seat 22 having an internal thread 221, and the outer wall of the threaded seat 22 having an anti-slip and anti-pull-out structure 24 connected to the pipe fitting 1, the threaded seat 22 being integrally injection molded to the pipe fitting 1. Preferably, the internal thread 221 is a G1 / 2 or G3 / 4 thread.

[0032] With the above structure, the water-stopping pipe fitting of this utility model has a threaded seat 22 integrally integrated on the outer shell 21. The threaded seat 22 is connected to the pipe fitting 1 as a whole for the installation of angle valves and faucets. Since the threaded seat 22 is specially formed on the outer shell 21, the thread length inside the threaded seat 22 can be made longer than the internal thread 221 in the traditional installation interface, ensuring sufficient thread depth when installing faucets or angle valves. The anti-slip and anti-pull-out structure 24 makes the connection between the threaded seat 22 and the pipe fitting 1 more secure.

[0033] Preferably, the anti-pulling structure 24 comprises an annular groove 241 on the outer wall of the threaded seat 22, and a plurality of protrusions 242 distributed annularly and spaced apart on the bottom of the threaded seat 22. The annular groove 241 mainly functions as an anti-pulling structure, and the material of the pipe 1 is embedded in the annular groove 241, so that the pipe 1 can provide sufficient axial resistance when the threaded seat 22 is subjected to an axial force. The protrusions 242 are distributed annularly and spaced apart, and the material of the pipe 1 is embedded in the groove between the protrusions 242, so that the threaded seat 22 can have sufficient connection strength with the pipe 1 in the circumferential direction.

[0034] Preferably, the pipe 1 is a straight, L-shaped or T-shaped pipe 1, and the stop valve 2 is arranged on the interface of the outward water outlet. In this way, different use requirements can be met. The pipe 1 is formed by injection molding of plastic material, and the outer shell 21 with the threaded seat 22 is used as an insert during injection molding. After injection molding, the stop valve 2 is integrally connected to the stop valve pipe.

[0035] Preferably, the internal thread 221 extends to the edge of the bottom surface of the inner cavity of the threaded seat 22. In this way, the axial length of the threaded seat 22 is fully utilized, and as many internal threads 221 as possible are arranged.

[0036] Preferably, the movable rod 3 is provided with a rubber pad 31 in the inner cavity of the threaded seat 22, and the diameter of the rubber pad 31 is less than the minor diameter of the internal thread 221, so that the rubber pad 31 is separated from the internal thread 221 and the axial movement of the movable rod 3 is smooth. When the movable rod 3 moves axially, it will inevitably sway left and right due to tolerances. If the rubber pad 31 is stuck in the internal thread 221 in the threaded seat 22, the movable rod 3 may not move smoothly outward. Preferably, the diameter of the rubber pad 31 is less than 0.95 times the minor diameter of the internal thread 221, so as to reduce the rubber pad 31 and the internal thread 221 as much as possible.

[0037] Preferably, the movable rod 3 is provided with a water stop part 32 made of rubber; one end of the shell 21 is provided with a water inlet 23, and when the movable rod 3 is in the water stop position, the water stop part 32 blocks the water inlet 23; the water stop part 32 is provided with a water blocking conical surface 321 at one end facing the water inlet 23, and is provided with a space conical surface 322 at one end away from the water inlet 23. After the angle valve is installed into the pipe 1, the movable rod 3 is pushed inward, so that the water path is opened, and water flows to the angle valve. After the angle valve is removed, the movable rod 3 moves outward, so that the water path is closed. The water blocking conical surface 321 is arranged to enable the water stop part 32 to sufficiently block the water inlet 23, and at the same time, to guide the water flow when the water path is opened. The space conical surface 322 has the function of guiding the water flow, and for L-shaped and T-shaped pipes 1, the space conical surface can also reduce the interference between the water stop part 32 and the inner wall of the curved pipe 1.

[0038] Compared with the prior art, the utility model discloses a threaded seat 22 is arranged on the water stop valve 2, the anti-skid and anti-pulling structure 24 is arranged on the threaded seat 22 and is integrally connected with the pipe 1, so that the stability of the structure is ensured. After the angle valve or the faucet is removed, the water stop valve 2 can automatically stop water, and the trouble of closing the water valve back and forth is avoided.

[0039] The above embodiment and drawing are not limited to the product shape and style of the utility model, and any ordinary technical personnel in the technical field can make appropriate changes or modifications, which should be regarded as not departing from the patent category of the utility model.
