BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fastener, and more particularly to a quick-release and quick-installation nut.

2. Description of the Prior Art

A nut is a common fastener used to connect and fix a device. It is generally used in conjunction with a screw rod. Through the cooperation of the nut and the screw rod, a component or device is fastened. According to the needs of applications, nuts have various structures. When in use, a conventional nut is rotated from the end of a screw rod and slowly moved to the locking position for locking. It takes a long time for locking and cannot quickly install the nut and the screw rod. This is not beneficial for fast installation of nuts. Especially for the space where a faucet needs to be installed on the basin in the bathroom, if the nut and the screw rod are used for installing the faucet, it is quite inconvenient to install the faucet.

An inner wall of the first threaded block and an inner wall of the second threaded block are formed with inner threaded surfaces for cooperating with an outer threaded surface of the screw rod. A right end of the first threaded block is detachably connected to a right end of the second threaded block. A left end of the first threaded block is hingedly or detachably connected to a left end of the second threaded block.

Preferably, the right end of the first threaded block is detachably connected to the right end of the second threaded block through a first connecting member. One of the right end of the first threaded block and the right end of the second threaded block is provided with a first connecting portion. The other of the right end of the first threaded block and the right end of the second threaded block is provided with a second connecting portion. Two ends of the first connecting member are provided with a first elastic claw portion a second elastic claw portion, respectively. The first elastic claw portion is configured to clasp the first connecting portion. The second elastic claw portion is configured to clasp the second connecting portion.

Preferably, the first elastic claw portion is rotatable to clasp the first connecting portion.

Preferably, one end of the second elastic claw portion of the first connecting member is provided with a first pull piece.

Preferably, the left end of the first threaded block is detachably connected to the left end of the second threaded block through a second connecting member. One of the left end of the first threaded block and the left end of the second threaded block is provided with a first coupling portion. The other of the left end of the first threaded block and the left end of the second threaded block is provided with a second coupling portion. Two ends of the second connecting member are provided with a first elastic hook portion and a second elastic hook portion, respectively. The first elastic hook portion is configured to clasp the first coupling portion. The second elastic hook portion is configured to clasp the second coupling portion.

Preferably, one end of the first elastic hook portion of the second connecting member is provided with a second pull piece.

Preferably, one of the first threaded block and the second threaded block is provided with a positioning post on an end portion thereof, and the other of the first threaded block and the second threaded block is provided with a positioning hole or a positioning groove on an end portion thereof for insertion of the positioning post.

After adopting the above technical solutions, the right end of the first threaded block is detachably connected to the right end of the second threaded block, and the left end of the first threaded block is hingedly or detachably connected to the left end of the second threaded block. It is easy to disassemble and assemble the first threaded block and the second threaded block of the nut body.

When the nut body of the present invention is to be installed to the screw rod, first, the first threaded block and the second threaded block of the nut body are separated. Then, the first threaded block and the second threaded block are moved to both sides of the screw rod to be locked. Next, the first threaded block and the second threaded block are connected, so that the inner threaded surfaces of the first threaded block and the second threaded block are engaged with the screw rod.
