Field of the Invention
The present invention relates to a connecting structure, and more particularly to a connecting structure for an outlet pipe of a faucet.
Description of the Prior Art
A conventional faucet contains a body, and the body includes an outlet pipe connected therewith and a control valve accommodated therein, and an upper end of the control valve has a rotary lever fixed thereon, such that the rotary lever is rotated to drive the control valve, and the control valve turns on/off the faucet and controls water flow.
The body of the conventional faucet is casted from metal material, such as copper or stainless steel, but the body has many curved channels defined therein, so it is casted poorly and is manufactured complicatedly at a high cost. In addition, the faucet becomes a defective product, has a heavy weight, and cause environmental issues. To overcome such a problem, an outlet pipe is separated from a body of an assemblable faucet.
This assemblable faucet contains the body and the outlet pipe which are welded together along a connection seam, and then the body and the outlet pipe are polished, thus producing high processing cost. Furthermore, the body and the outlet pipe are polished roughly to cause air pores or false welding, so water leaks out of the air pores, and the body and the outlet pipe cannot be securely welded together because of the false welding. In a welding process, waste gas and high temperature will damage worker's health.
A connecting structure for an outlet pipe of a faucet is developed to solve above-mentioned defects and contains a hollow body in a cylinder shape, and the body includes at least one screwing orifice defined on a peripheral wall thereof to match with a connecting tube, a fitting tube, a connecting tube by which the outlet pipe is defined. The fitting tube has an outer screwing section to screw with the at least one screwing orifice of the body, and a stop ring is applied to stop water, such that the outlet pipe is in connection with the body.
However, the at least one screwing orifice is defined on the peripheral wall of the body, so the peripheral wall of the body has to be thick to arrange sufficient threads in the at least one screwing orifice so as to screw with outer threads of the fitting tube tightly. Nevertheless, the body is made of metal material to have high production cost, heavy weight, and inconvenient transportation.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a connecting structure for an outlet pipe of a faucet in which a circular orifice is stamped on an inner wall of the body, a fitting tube extends outward into the body from a peripheral side of the circular orifice, inner threads are formed in the circular orifice and the fitting tube, wherein the body is thin to form the inner threads for screwing with an outer threaded tube of a rotary connector of the outlet pipe securely, thus reducing manufacture material and cost of the body. Preferably, the faucet is lightweight and is conveyed easily.
Accordingly, a connecting structure for an outlet pipe of a faucet provided by the present invention contains: a body and an outlet pipe.
The body is a thinly hollow cylinder and includes a circular orifice stamped on an inner wall thereof, a fitting tube horizontally extending outward to the body from a peripheral side of the circular orifice, and inner threads formed in the circular orifice and the fitting tube as one piece.
The outlet pipe includes a connecting segment, an outlet segment, and a rotary connector fitted and limited in the connecting segment. The rotary connector has an outer threaded tube partially extending out of the connecting segment of the outlet pipe to screw with the inner threads formed in the circular orifice and the fitting tube, thus securely connecting the outlet pipe and the body together.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
With reference to
Referring to
Thereby, the connecting structure for the outlet pipe contains advantage as follows:
The circular orifice 11 is stamped on the inner wall of the body 1, the fitting tube 12 extends outward into the body 1 from the peripheral side of the circular orifice 11, the inner threads 13 are formed in the circular orifice 11 and the fitting tube 12 as one piece, wherein the body 1 is thin to form the inner threads 13, 13a for screwing with the outer threaded tube 233 of the rotary connector 23 of the outlet pipe 2 securely, thus reducing manufacture material and cost of the body 1. Preferably, the faucet is lightweight and is conveyed easily.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
