Description

Welding-free, anti-seepage and anti-loosening water heater anode rod nut

Technical Field

The utility model relates to a nut, in particular to a welding-free, anti-seepage and anti-loosening nut for an anode bar of a water heater.

Background

The nut is a nut, and is screwed together with a bolt or a screw rod to play a role in fastening, and one element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and other types according to different materials. The nut is a part for tightly connecting mechanical equipment, and the nut and the bolt with the same specification can be connected together through the threads on the inner side.

The existing nut, especially the nut for the anode bar of the water heater, cannot well play a role in preventing water seepage, and needs to be welded during connection, so that the installation and the disassembly are very inconvenient. At present, the screw rod with the water seepage prevention structure has the torsion larger than 10N/requirement when the unloading can not be achieved, and the screw rod below M6 can be broken when the torsion is larger than 10N/M.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, the utility model provides a welding-free, anti-seepage and anti-loosening screw cap for the anode bar of the water heater. The utility model discloses a following technical scheme realizes.

A welding-free, seepage-proof and anti-loosening water heater anode rod nut comprises a nut body, wherein the nut body consists of a nut and a flange surface; the nut is a hexagon nut; the bottom end of the flange surface is fixedly provided with a mounting hole with internal threads; the internal thread is a built-in anti-skid rotary thread; a nut column is arranged inside the nut body; the interior of the nut body is of a wedge-shaped structure.

Preferably, the size model of the internal thread is G3/4; the internal thread is of a tooth-shaped structure.

Preferably, the inner diameter of the nut column is 6mm-12 mm; the height of the nut column is 6mm-12 mm.

The utility model has the advantages that: the utility model discloses rational in infrastructure, the modern design, the internal thread is built-in stealthy anti-skidding rotatory screw thread, adds built-in stealthy nut post simultaneously, and it is convenient to install, has prevention of seepage water, antiskid, locking moving, exempts from welded function, can popularize and apply by a large scale.
