Faucet pin combination structure

Abstract

The invention discloses a faucet pin assembling structure. An expansion cavity is formed at the position, matched with a valve element, in a pin. The pin comprises a pin body, an assembly part and a metal pipe sleeve, wherein the pin body and the assembling part are formed in an injection molding mode, the metal pipe sleeve is assembled with the outside of the pin body and is provided with outer threads, the pin body is provided with an opening at the position, where the pin is matched with the valve element, of the expansion cavity, the assembling part is formed right corresponding to the opening of the pin body, namely, the complete expansion cavity is formed when the assembling part is assembled with the opening of the pin body, and the assembling part is matched with a sealing piece, is assembled with the pin body in a sealed mode and meanwhile is assembled with the metal pipe sleeve. The pin body and the assembling part are independently formed and then are assembled to form the pin expansion cavity, the assembled integrality, firmness and matching strength of the pin body and the assembling part are guaranteed by the metal pipe sleeve, the faucet pin structure formed in a split mode can adopt plastic materials to form part components through moulds in an injection molding mode, and therefore the faucet pin assembling structure effectively reduces the manufacturing cost, meets the requirement for environmental protection and improves market competitiveness of markets.

Description

technical field [0001] The invention relates to a mounting part of a water outlet device, in particular to a combination structure of faucet pins. Background technique [0002] The pins of the faucet are parts used to match the faucet spool and the water supply pipe. figure 1 , 2 As shown, when the spool 2' is matched with the pin 1', in order to make the water flow passing through the spool 2' form a water passage in the pin 1', it is necessary to form a Enlarging cavity 11' to form a water channel. Pins with such a structure must be completed by casting or secondary machining. Therefore, although the current pin structure has better matching strength, it still has the following problems: [0003] 1. High material cost: It is completely made of metal copper, and the material cost remains high. [0004] 2. Poor environmental protection: Metal copper is used as a water passage, and there is a possibility that heavy metals exceed the standard. [0005] 3. High production...

AI Technical Summary

Problems solved by technology

[0003] 1. High material cost: it is completely made of metal copper, and the material cost remains high

[0004] 2. Poor environmental protection: metal copper is used as a water passage, and there is a possibility that heavy metals exceed the standard

[0005] 3. High production cost: secondary machining is required to form cavity expansion, which is time-consuming and labor-intensive, so the overall production cost is relatively high
