Description

Technical Field

[0001] The utility model relates to the field of faucet accessories, in particular to an internally 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 internally connected 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 internally 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 inlet coaxially arranged with its center and a water diversion pipe offset from its center, the first water inlet, the 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 being connected, the water diversion pipe extending to the outside of the main body sleeve at one end away from the support baffle and being welded with 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 support baffle to form a partition with the first water inlet and the water diversion pipe on the side of the support baffle facing the first connecting internal thread, thereby realizing the control of water passage; the support baffle and the main sleeve are welded to ensure the connection strength while ensuring the sealing and reliability; since the first water inlet corresponds to the water outlet at the bottom center of the valve core, and the water outlet on the side wall of the valve core needs to guide the water passage to the support baffle position, the water diversion pipe is offset.

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

[0009] The present invention is further configured such that the second water inlet is a quick water inlet.

[0010] 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.

[0011] The present invention is further configured such that the cross-section of the water diversion pipe at the inner cavity of the main casing is spindle-shaped, elliptical, or waist-shaped, and the minor axis thereof points to the center of the support baffle.

[0012] In the above structure, due to the limitation of the inner diameter of the main casing, under the premise of ensuring the inlet and outlet water flow, if the cross-section of the water inlet pipe at the inner cavity of the main casing is circular, it will interfere with the first water inlet. Therefore, it is set to a spindle shape, an elliptical shape or a waist shape to make way for the first water inlet while ensuring the flow.

[0013] The utility model is further configured such that after the water diversion pipe passes through the inner cavity of the main casing, its cross section returns to a circular shape and is connected to the second water inlet.

[0014] In the above structure, a good docking transition between the water diversion pipe and the second water inlet is ensured.

[0015] The present invention is further configured such that a side of the support baffle facing the first connecting internal thread is formed with an annular sealing area located between the outer side of the first water inlet and the water diversion pipe.

[0016] In the above structure, the annular sealing area is used to abut and fit with the sealing ring at the lower end of the valve core to prevent water from jumping between the first water inlet and the water diversion pipe.

[0017] 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.

[0018] 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.

[0019] The utility model is further configured such that the main body sleeve, the support baffle, the first water inlet, the water diversion pipe, the second water inlet, and the threaded ring are all made of stainless steel.

[0020] In the above structure, corrosion resistance is ensured while strength is ensured.

[0021] The present invention is further configured such that an outer wall of the main sleeve is provided with a mounting thread.

[0022] In the above structure, the threaded fitting nut is installed to install the main sleeve.

[0023] 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.
