Description

Tap locking assembly

Technical Field

The utility model relates to a tap technical field, concretely relates to be a tap locking Assembly.

Background

The traditional faucet mounting and locking assembly adopts an annular nut to mount and lock a faucet so as to mount and fix the faucet on a hand basin or a wash basin. When the water faucet is installed, the water faucet, the threaded pipe and the water inlet hose are assembled, then the water faucet penetrates through the hand basin or the water faucet installation hole from the end of the water inlet hose, the water faucet is placed on the installation hole, the locking nut is sleeved at the tail end of the water inlet hose, the locking nut is sleeved on the threaded pipe fixedly connected with the water faucet and in threaded connection with the threaded pipe, and the locking nut is screwed tightly, so that the basin body of the hand basin or the wash basin on the periphery of the threaded pipe is tightly clamped between the water faucet and the locking nut.

However, after the locking nut is locked, the locking nut is easy to loosen after long-term use, so that the faucet above the locking nut is easy to rotate and loosen, and the use feeling of the faucet is influenced. In order to solve the problem that the locking nut is easy to loosen, the chinese patent CN210265441U provides a mode for setting a locking screw hole to realize looseness prevention, which specifically comprises the following steps: the screw is screwed on the locking screw hole, so that the locking force of the locking nut can be further enhanced, and the installation of the faucet is more stable. The hard gasket is used for bearing upward locking thrust from a screw on the locking screw hole, so that the locking thrust is uniformly distributed, and the basin stand is uniformly stressed. The elastic gasket is used for protecting the basin stand and avoiding scraping flowers or damaging the basin stand.

However, once the screw in the lock screw hole is locked, the relative position between the screw and the lock nut is kept unchanged, that is, the distance between the upper end of the lock wire and the lock nut is kept unchanged, and once the lock nut is loosened on the screw tube, the screw descends along with the descending of the lock nut, that is, the upper end of the screw and the hard gasket are also loosened. Therefore, the lock nut of CN210265441U functions to make the nut not easy to change from the locked state to the loosened state, and once the lock nut is slightly loosened, the lock nut will be accelerated to change to the looser direction.

In view of the above, the present inventors have made extensive studies on the above-mentioned drawbacks of the prior art, and have made this invention.
