Abstract

The invention relates to a novel pressure enclosing nut device which comprises a pressure enclosing nut and screws, wherein the pressure enclosing nut is provided with grooves in the circumference direction; and the end surface of the pressure enclosing nut is provided with two screw holes. Compared with the prior art, the pressure enclosing nut device has the advantages of bearing certain pressure in a long time and maintaining not to be loose and the like.

Description

technical field [0001] The invention relates to a nut, in particular to a novel sealing and pressing nut device. Background technique [0002] At present, the nuts available on the market are standard parts, and their function is only to cooperate with the bolts to connect two solids, which cannot bear a certain pressure, and are easy to fall off due to vibration during equipment use and transportation. Ordinary nuts cannot meet the needs in situations where it is necessary to withstand a certain pressure for a long time without loosening. Contents of the invention [0003] The object of the present invention is to overcome the defects of the above-mentioned prior art, and provide a new type of sealing nut device which is functional, capable of withstanding a certain pressure, safe and reliable. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A new sealing nut device, characterized in that the device inclu...
