Description

a faucet

technical field

The utility model relates to the field of faucets, in particular to a faucet body.

Background technique

During the design and assembly of the faucet, the connection structure between the valve core, the faucet shell and the water inlet and outlet pipes often determines most of the production cost. For example, the existing cast faucet shell is close to solid as a whole, so it will lead to excessive materials. , it is necessary to drill corresponding water channels on the faucet shell to connect the water inlet and outlet pipes and the valve core, and to process the inner and outer walls of the faucet shell, resulting in an increase in material costs and production and processing costs;

Therefore, there has been a valve core with its own connection interface (usually a threaded port), but the cost of this type of valve core is higher than that of an ordinary valve core, and the watertightness of the threaded port connection is weaker than that of the traditional valve core. The back cover of the traditional spool is often longer, resulting in the overall length of the spool being much longer than the traditional spool, which is not conducive to shortening the length of the installation position of the spool, and it is difficult to effectively control the dimensional parameters of the faucet shell.

Utility model content

Based on the above problems, the purpose of this utility model is to provide a faucet body with simple structure, convenient installation, reliable sealing and low manufacturing cost.

In view of the above problems, the following technical solutions are provided: a faucet body, including a faucet housing, the faucet housing is provided with a valve core installation position, and the inner cavity of the valve core installation position communicates with the inner cavity of the faucet housing. The bottom of the spool installation position is provided with a support part; the bottom of the spool installation position is also provided with a spool adapter piece, the spool installation position is provided with a spool, and the rear end of the spool and the spool adapter piece offset and press the valve core adapter piece on the support part to fix; the valve core adapter piece is provided with a water inlet hole and a water outlet hole, and the water inlet and water outlet of the valve core are connected with the water inlet hole and the water outlet hole respectively. Connected, the side of the valve core adapter piece facing away from the valve core is provided with a water inlet pipe and a water outlet pipe respectively connected with the water inlet hole and the water outlet hole.

In the above structure, the traditional connection method of punching a hole on the faucet shell to fit the valve core or using a valve core with a wire port is replaced with a valve core adapter piece, which is screwed to the valve core installation position port when the valve core is installed. The gland at the position presses the spool tightly, so that the spool and the spool adapter piece are tightly opposed, and the spool adapter piece is supported by the support part at the bottom of the spool installation position, ensuring the connection between the spool and the spool. Since this structure does not require a spool with a threaded port, and the waterway is laid out through the casting of the faucet shell, it can greatly save production costs, improve production and assembly efficiency, and ensure reliable sealing. The adapter piece of the spool directly diverts water through the water inlet pipe and the outlet pipe to connect the upstream and downstream pipelines; compared with the existing connection method of punching holes on the faucet shell to fit the spool or adopting a spool with a wire port , the connection point is often relatively inward (that is, close to the installation position of the valve core), so limited by the narrow space, it will also cause troublesome connections. This structure can directly connect the water inlet pipe and the water outlet pipe through the water inlet pipe and the water outlet pipe. The wire port is led to the outside or away from the installation position of the valve core, avoiding space restrictions and ensuring the convenience of pipeline connection.
