Description

Technical Field

[0001] The utility model relates to the field of faucet accessories, in particular to an externally connected single-joint faucet body. Background Art

[0002] The valve core installed on the existing single-joint faucet body generally has a water outlet mode of bottom inlet and side outlet or side inlet and bottom outlet. Therefore, the water channel on the side needs to be transferred to the bottom to achieve bottom inlet and bottom outlet. In order to ensure the flow rate of the water channel and its reasonable layout, injection molding is currently mostly used for production. However, the problem that comes with it is that the plastic parts have poor pressure bearing capacity, low overall strength and are easy to break. Increasing the wall thickness will increase material costs, and there is also the problem of shrinkage. Utility Model Content

[0003] In view of the above problems, the present invention aims to provide an external single-joint faucet body with a compact structure, high strength and low production cost.

[0004] In response to the above problems, the following technical solutions are provided: an externally connected single-joint faucet body, comprising a main body sleeve, one end of which is provided with a first connecting internal thread; and also comprising a support baffle welded and fixed to the inner wall of the main body sleeve, the side of the support baffle facing away from the first connecting internal thread being welded with a first water diversion pipe coaxially arranged with its center and a second water diversion pipe offset from its center, the first water diversion pipe protruding outward from the support baffle at one end toward the first connecting internal thread and being welded and fixed with a bearing plate spaced apart from the support baffle, the outer diameter of the bearing plate being smaller than the outer diameter of the support baffle and forming a water-passing gap between the inner walls of the main body sleeve; the first water diversion pipe, the second water diversion pipe and the inner cavity of the main body sleeve on the side of the support baffle facing the first connecting internal thread are connected, the first water diversion pipe and the second water diversion pipe extend to the outside of the main body sleeve at one end away from the first connecting internal thread and are respectively welded with a first water inlet and a second water inlet.

[0005] In the above structure, the main sleeve is made of pipe cutting, so its length can be arbitrarily controlled according to actual needs; the first connecting internal thread is used to install the valve core, and the lower end of the valve core is against the bearing plate to form a partition against the first water diversion pipe and the second water diversion pipe facing the first connecting internal thread of the support baffle, thereby realizing the control of water passage; the welding of the support baffle and the main sleeve ensures the connection strength while ensuring the sealing and reliability; because the bearing plate is overhead, the first water diversion pipe and the bearing plate and the second water diversion pipe and the support baffle are misaligned, which provides the necessary conditions for good sealing contact between the lower end of the valve core and the bearing plate, and also avoids the first water diversion pipe and the second water diversion pipe being too close when they are located on the same support baffle, resulting in the effective contact sealing area of ​​the valve core bottom being too narrow, leading to water leakage.

[0006] The utility model is further configured such that the outer edge of the support baffle is provided with a reinforcement edge formed by stamping and stretching, and the reinforcement edge is welded and fixed to the inner wall of the main body sleeve.

[0007] In the above structure, the reinforcing edge not only improves the strength of the supporting baffle, but also increases the reliability when it is welded to the inner wall of the main casing.

[0008] The utility model is further configured such that the outer edge of the bearing plate is provided with a plurality of support ribs spaced apart along its circumferential direction and formed by stamping and stretching toward the support baffle, and the support ribs abut against the support baffle.

[0009] In the above structure, the supporting ribs provide stable support for the bearing plate to prevent it from being skewed. At the same time, the supporting ribs can be welded to the supporting baffles as needed, and the bearing plates arranged at intervals can ensure reliable conduction of water flow.

[0010] The present invention is further configured such that the first water inlet is provided with a second connecting internal thread.

[0011] The present invention is further configured such that the second water inlet is a quick water inlet.

[0012] In the above structure, the first water inlet and the second water inlet are both used to connect to the water inlet and outlet pipes.

[0013] The present invention is further configured such that the first water inlet pipe extends out of the main body sleeve and then tilts away from the second water inlet pipe to make way for the installation of the first water inlet.

[0014] In the above structure, the installation of the first water inlet is ensured to avoid interference.

[0015] The present invention is further configured to further include a threaded ring welded and fixed at the end of the main sleeve, and the first connecting internal thread is located on the inner surface of the threaded ring.

[0016] In the above structure, the threaded ring is connected to the main sleeve by welding, and there is no need to consider the extra wall thickness material required when processing the first connecting internal thread, ensuring that the wall thickness of the main sleeve is as thin as possible when selecting materials.

[0017] The present invention is further configured such that the main body sleeve, the supporting baffle, the first water diversion pipe, the second water diversion pipe, the bearing plate, the first water inlet, the second water inlet, and the threaded ring are all made of stainless steel.

[0018] In the above structure, corrosion resistance is ensured while strength is ensured.

[0019] The present invention is further configured such that an outer wall of the main sleeve is provided with a mounting thread.

[0020] In the above structure, the threaded fitting nut is installed to install the main sleeve.

[0021] The beneficial effects of the utility model are as follows: the overall structure is simple, the processing is flexible, the weight is light and the material loss is small, both the strength and the pressure bearing capacity are guaranteed, and the service life is effectively improved.
