Description

Two-handle faucet body structure

technical field

The utility model relates to the field of kitchen and bathroom, in particular to a body structure of a two-handle faucet.

Background technique

Existing two-handle faucets are equipped with an H-shaped faucet body. The horizontal tube in the middle of the faucet body is provided with an outwardly drawn water outlet, and each of the two ends of the horizontal tube is connected with an upwardly protruding tubular valve seat for installing a water regulating valve; the inner hole of the horizontal tube connects the water outlet with the The inner cavities of the two valve seats at both ends are connected; the outer circumference of the upper opening of each valve seat is equipped with external threads for the installation of water regulating valves; the bottom of each valve seat is provided with a water inlet and communicates with the water inlet and extends downward water inlet pipe. The outer circumference of each water inlet pipe is provided with external threads, so that the faucet body can be connected and fixed with the panel of the bathroom equipment through fasteners.

The faucet body of the early two-handle faucet was cast into a blank with copper, and then the blank was obtained by complex machining. Due to the shortage of copper resources, high machining cost and low yield rate, the copper faucet body is expensive. For this reason, people try to replace copper with plastic, and use injection molding process suitable for mass production instead of complex machining to produce a plastic faucet body of a double handle faucet. Due to the particularity and complexity of the plastic faucet body structure of the double-handle faucet, if the conventional injection molding process is used, the inner hole of the horizontal tube on the faucet body cannot be formed; therefore, an integrated plastic faucet body cannot be produced, and segmental injection molding must be used. It is a production method in which two side bodies and a central body are made, and then the three are spliced together. Since the side body is integrally injected with plastic, its strength is not as strong as that of a copper faucet. Therefore, excessive force should not be used when installing the side faucet body to the panel of the bathroom equipment through fasteners, otherwise the water inlet pipe of the side body will easily crack due to stress. , if it is not tightened forcefully, the body of the side faucet will not be stably fixed on the panel. Therefore, copper pins are embedded in the water inlet pipe of the side body or the side body is secondarily injected onto the copper pins to form a semi- Copper and semi-plastic faucet body; this kind of secondary injection molded half-copper and half-plastic faucet body cannot be completely combined to achieve the sealing effect due to the different materials between the water inlet pipe and the copper pin, and the copper pin is the same as the water inlet pipe. It is flush. In order to ensure the safe installation of the pipe fittings and the faucet body, the pipe glue and the pipe fittings are directly sealed in the water inlet pipe to avoid water leakage; but this connection method is easy to cause the side body of the plastic material to be damaged. The water inlet pipe is cracked by stress, and eventually the water will leak out, which will affect the use.
