Description

TECHNICAL FIELD

[0001] The utility model relates to sanitary equipment technical field, especially a nut extender and assembly kit. BACKGROUND

[0002] In the field of sanitary equipment installation, including the installation of sanitary equipment such as water outlet faucet, water inlet valve and wash basin, an external thread is usually arranged on the water inlet pipe or the drain pipe of the sanitary equipment, and a nut is arranged on the water inlet pipe or the drain pipe for fixation, that is, the nut is connected and fixed by means of screw rod and nut cooperation.

[0003] For example, when installing a water outlet faucet, an external thread is arranged on the installation and fixation pipe of the water outlet faucet, and then the nut is screwed on the installation and fixation pipe of the water outlet faucet to fix the water outlet faucet on the installation panel. The nut is arranged in a cylindrical shape in order to be sleeved on the fixation pipe. Since other pipelines are also installed below the installation panel, the nut cannot be arranged too long, otherwise it is easy to interfere. However, when the nut is arranged relatively short, it is difficult to use a rotating tool below the installation panel, and the nut is rotated by relying on human power, so that the nut is relatively difficult to rotate, and it is easy to cause the loosening of the threaded connection.

[0004] Therefore, in order to solve the problem that the nut is difficult to rotate when the nut is arranged relatively short, the utility model provides a nut extender which overcomes the above-mentioned defects, and the utility model is generated accordingly. CONTENT OF THE UTILITY MODEL

The outer retaining edge 21 is set to a non-circular ring shape that matches the side wall of the nut 20 to limit the circumferential relative rotation of the outer retaining edge 21 and the side wall of the nut 20.

[0036] Optionally, the extension part 1 and the connecting part 2 are configured to be cylindrical, and the side walls of the extension part 1 and the connecting part 2 are provided with a groove 24 along the axial direction. The groove 24 can increase the clamping elasticity of the extension part 1 and the connecting part 2, and at the same time, can adapt to the clamping of nuts 20 with slightly different diameters.

[0037] Optionally, the outer side wall of the extension portion 1 is provided with ribs 11 along the circumferential direction to increase the friction of the extension portion 1 when held by hand, thereby making it easier to hold the extension portion 1.

[0039] In this embodiment, optionally, the outer retaining edge 21 is set to a polygon and the inner retaining edge 22 is set to a circular ring.

[0040] When rotating the nut 20, the side wall of the nut 20 is inserted into the limited space 23 formed between the outer retaining edge 21 and the inner retaining edge 22. The outer retaining edge 21 is configured to be non-circular (can be polygonal) in shape to match the side wall of the nut 20 to limit the circumferential relative rotation of the outer retaining edge 21 and the side wall of the nut 20. The rotation of the extension portion 1 drives the nut 20 to rotate, thereby locking the nut 20. Therefore, the rotation of the nut 20 is convenient, so that the nut 20 can be tightened by hand.
