Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a structure of a faucet, and in particular to welding a water pipe to a conventional faucet. The present invention relates to a faucet structure in which a water discharge pipe is screwed with a structure that eliminates the above drawbacks.

[0002]

[Prior art]

  Most of the traditional faucets are molded, and the faucets are limited by the mold. The modeling of was extremely limited. In the process of molding, many environmental issues However, the improvement of the faucet appearance has been studied in recent years, and the well-known integral molding Fading faucets are no longer able to meet market demands. For this reason , The vendors actively tried to change the faucet molding, and the mainstream of the change was the faucet body and the water pipe. There is a change in shape between. For example, FIG. 1 is a typical one, and the faucet body 10 and the water discharge are shown. The pipe 11 is generally joined by welding the faucet body 10 and the outlet pipe 11 along the joining line. Are combined in a manner to form a faucet as shown in FIG. The structure is the faucet body The water discharge hole 12 of 10 and the water discharge pipe 11 are connected. However, such a joining method is There is such a drawback.   1. Between the faucet main body 10 and the water outlet pipe 11 in the cylindrical direction, two curved surfaces intersect each other. It is defined as a dimensional space curve intersection line, and the intersection angle of a certain part is defined as a blind spot. It is extremely difficult and costly to finish, and the appearance after polishing The quality does not meet the aesthetic requirements.   2. The problem of forming air holes during the welding process cannot be avoided, and the phenomenon of missing welds Occurs, the air holes form the phenomenon of water leakage or launching, and the lack of welding condition weakens the bond. A slight impact formed a fracture.   3. Waste gas and high temperature generated in the welding process cause occupational injury to employees.

[0003]

[Problems to be solved by the device]

  Therefore, it is a good snake that solves the above-mentioned drawbacks formed by welding the faucet. Providing a joint structure of the mouth is the problem solved by the present invention.

[0004]   The main purpose of the present invention is to provide a kind of tap pipe with a tap, which makes it difficult to use. Excessive polishing work process, greatly reduce the processing cost, It is to improve the view.

[0005]   The second object of the present invention is to provide a faucet with a kind of water pipe installed by screwing. Eliminates defective products that may cause air hole problems or weld loss phenomena depending on the composition, and improves yield. To effectively reduce the cost of defective product loss.

[0006]   Another object of the present invention is to provide a faucet screwed with a kind of water pipe, To eliminate occupational injuries that can be formed by the composition's high temperatures and waste gases in welding operations is there.
