Sealing structure for plastic steel faucet

Abstract

The invention discloses a sealing structure for a plastic steel faucet. The sealing structure for the plastic steel faucet comprises a faucet main body; the faucet main body is composed of a plastic base and a metal shell wrapping the outer layer of the plastic base; a threaded joint is formed on a water inlet in the metal shell; and a sealing plug is arranged in the threaded joint, clings to the inner wall of the threaded joint, is provided with a water passing hole and is provided with a plug head in the water inlet direction of the water passing hole in an extending manner to be inserted into the water inlet. According to the sealing structure, as for the faucet main body of the plastic steel faucet, the inner layer is made of a plastic material, and the outer layer is made of a metal material, so that the problems of harmful substances, such as lead, contained in the faucet, quality of the faucet and the like are solved; and as the sealing plug is arranged at the water inlet, a water flow is prevented from seeping into a gap between the plastic base and the metal shell to cause the phenomena of dripping and leakage of the faucet, and the sealing structure is of a practical and reliable structure, is more beautiful and elegant in appearance and improves the quality of a product.

Description

technical field [0001] The invention relates to a faucet, in particular to a sealing structure of a plastic-steel faucet.

[0003] In the market, there are metal and plastic materials used to make the main body of the faucet. This type of faucet is called a plastic-steel faucet, which can solve the above-mentioned problems of the casting faucet. However, there is a gap between the metal shell and the plastic body in the plastic-steel faucet. When the pressure is large enough, the water flow will leak out from the gap, causing the faucet to drip and reduce the service life of the faucet
