Abstract
The utility model discloses a hexagon nut for sealed environment, including outer hexagon, screw hole, its characterized in that are established to outer hexagon center: the lower terminal surface of outer hexagon sets up the annular groove around the screw hole, and the tank bottom of annular groove is equipped with grease that through -hole and outer hexagon outer wall be equipped with and clamp -ons the hole and communicate with each other. The utility model is used for sealed environment is clamp -oned the grease and can be prevented effectively that the clearance in threaded connection hole from intaking after the installation.
Description
Technical field
The utility model relates to a kind of Fastener products, is specifically related to a kind of hexagon nut that can be used for sealed environment.
Background technique
In the nut series of Fastener products, the consumption of hexagon nut is maximum.The installation occasion prevented into water is needed at some threaded connection holes, often sealing gasket to be set at the bottom end face of nut when nut is installed, but obviously only just there is better sealing effect when fastening end face is more smooth, if thread pitch is larger simultaneously, that water can enter in threaded connection hole by thread pitch, and sealing gasket now does not just seal substantially.
Summary of the invention
In view of current known technology Problems existing, the technical problems to be solved in the utility model is to provide a kind of for sealed environment, clamp-ons grease and can effectively prevent from being threaded the hexagon nut of interporal lacuna water inlet after installation.
The utility model is implemented by the following technical programs:
For the hexagon nut of sealed environment, comprise outer-hexagonal body, tapped hole is established at outer-hexagonal body center, it is characterized in that: the lower end surface of outer-hexagonal body arranges annular groove around tapped hole, and the bottom land of annular groove is provided with through hole and clamp-ons hole with the grease that the external wall of outer-hexagonal is provided with and communicate.
Grease is clamp-oned hole and is positioned at outer-hexagonal body on the side outer wall of bottom.
Adopt the hexagon nut of technique scheme, after fastening installation, clamp-on hole by grease and clamp-on grease in annular groove, grease will void-free tight encirclement at the port of threaded connection hole, all good seal action can be played from direction, face, fastening end or from thread pitch direction, thus effectively can prevent the interporal lacuna water inlet that is threaded, structure is simple, is highly suitable for sealed environment.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is direction, the bottom surface view of Fig. 1.
Embodiment
Details and the working principle of the utility model specific embodiment is described in detail below in conjunction with accompanying drawing:
As shown in the figure, hexagon nut for sealed environment of the present utility model, comprise outer-hexagonal body 1, tapped hole 2 is established at outer-hexagonal body 1 center, the lower end surface of outer-hexagonal body 1 arranges annular groove 3 around tapped hole 2, the bottom land of annular groove 3 is provided with through hole 4 and clamp-ons hole 5 with grease and communicate, and grease is clamp-oned hole 5 and is positioned at outer-hexagonal body 1 on the side outer wall of bottom.
