Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet assembly. Background Art

[0002] Faucets are often connected to water pipes in the wall using elbows. After assembly, one side of the faucet is against the wall, and the connection between the elbow and the faucet body requires a special method.

[0003] In the prior art, there is a Chinese utility model patent with a publication number of CN203413275U, which discloses an elbow connection assembly, including an elbow, a faucet body and a screw. The tail end of the elbow is connected to the wall, and the protruding end of the elbow is inserted into the inner cavity of the faucet body. The inner cavity accommodates a circular locking buckle, the locking buckle is sleeved on the elbow, a first locking hole is provided on the locking buckle, and a second locking hole is provided on the faucet body. The screw passes through the second locking hole and the first locking hole in sequence from the outside to the inside, and is used to lock the locking buckle and the elbow. The inner cavity accommodates a nut, and the nut is threadedly connected to the inner wall of the inner cavity to confine the locking buckle in the inner cavity.

[0004] The existing solutions have the following defects:

[0005] The nut is pressed against the locking buckle at the rear side of the locking buckle, which requires a sufficient platform to be left at the front side of the bent section of the elbow to fit the nut, extending the axial length of the elbow.
