Description

Technical Field

[0001] The utility model relates to the technical field of connecting devices, in particular to a water pipe connecting device. Background Art

[0002] In the prior art, the clamp ring used to clamp the pipe in the water pipe connecting device is generally a plastic copper clamp, which has strong applicability. However, the plastic copper clamp is at risk of breaking in the severe cold environment in northern my country, resulting in the problem of loose pipe clamping. In addition, the existing water pipe connecting device has a short lifespan, which affects the user experience. Therefore, a water pipe connecting device is needed to solve the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a water pipe connecting device to solve the problems in the background technology.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A water pipe connecting device includes a hollow internal thread head with external threads, a sealing ring, a clamping ring and a hollow compression sleeve base with internal threads, wherein the sealing ring is arranged in the internal thread head, the clamping ring is arranged in the compression sleeve base, the external thread of the internal thread head is matched and connected with the internal thread of the compression sleeve base, and the clamping ring is a copper clamping ring having a notch.

[0006] Preferably, the copper clamp ring includes an inclined side wall, and the compression sleeve base is provided with an inclined surface matching the inclined side wall.

[0007] Preferably, the sealing ring is a rubber sealing ring.

[0008] Preferably, a nut is fixedly sleeved on the inner thread head.

[0009] Preferably, the compression sleeve base includes a nut segment.

[0010] The above technical solution has the following beneficial effects:

[0011] By setting the copper clamp, it can be quickly inserted without wave, and the installation is easier;

[0012] Copper card rings are more applicable than the commonly used plastic-copper cards on the market. Plastic-copper cards are at risk of breaking in severe cold environments, while pure copper cards are not prone to breaking in severe cold environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] refer to Figure 1 to Figure 4 , the water pipe connecting device comprises an internal thread head 1 with an external thread and hollow, a sealing ring 5, a clamping ring and a compression sleeve base 2 with an internal thread and hollow, the sealing ring 5 is arranged in the internal thread head 1, the clamping ring is arranged in the compression sleeve base 2, the external thread of the internal thread head 1 is matched with the internal thread of the compression sleeve base 2, the internal thread head 1 and the compression sleeve base 2 are assembled by threaded connection, the internal thread head 1 comprises an external thread section 8, the external thread section 8 is connected to the compression sleeve base 2 by threaded connection, the clamping ring is a copper clamping ring 6, and a notch 7 is arranged on the copper clamping ring 6. After connection, the copper clamping ring 6 fits with the end of the external thread section 8, and pressure is applied to the copper clamping ring 6 through the end to deform and clamp the water pipe, and the end of the sealing ring 5 is partially or completely fitted with the copper clamping ring 6 to ensure sealing. When in use, the bellows is inserted into the hole of the compression sleeve base 2, and the copper clamping ring 6 is deformed by tightening the internal thread head 1 and the compression sleeve base 2, thereby clamping the bellows, thereby ensuring the connection reliability of the bellows;

[0019] The copper clamp ring 6 has a long service life and is not easy to break in a long-term severe cold environment, and can be used for a long time;

[0020] The copper clamp ring 6 includes an inclined side wall, and the compression sleeve base 2 is provided with an inclined surface matching the inclined side wall;

[0021] The sealing ring 5 is a rubber sealing ring, which plays a sealing role;

[0022] A nut 3 is provided on the fixing sleeve of the inner thread head 1, and the compression sleeve base 2 includes a nut section 4. The nut 3 and the nut section 4 are external hexagonal nuts. The nut 3 and the nut section 4 are provided to facilitate positioning and tightening or loosening during installation and connection.

[0023] By setting the copper clamp ring 6, it can be quickly inserted without wave, and the installation is relatively easy; compared with the common plastic copper clamp on the market, the copper clamp ring 6 has strong applicability on the one hand. The plastic copper clamp 6 has the risk of breaking in the severe cold environment in the north, while the pure copper clamp does not have this potential risk; on the other hand, it has low cost and is more conducive to promotion.
