And shield, the top of the hex nut body are equipped with fixing body, the outer wall of the fixing body is equipped with screw thread, the shield
Inner wall is equipped with installation convex edge, and the inner wall of the installation convex edge is equipped with screw thread, is threadedly coupled between the fixing body and installation convex edge
Cooperation, the lower end surface of the shield are equipped with the first sealing ring, offer annular mounting groove below the hex nut body,
The washer is mounted in annular mounting groove by spring, and the lower end surface of the washer is evenly distributed with anti-slop serrations.
Preferably, the outer ring of the fixing body sets stop bosses, under the retention bead portion and installation convex edge
End face matches, and seal groove is equipped between the retention bead portion and fixing body, is equipped with the second sealing ring in the seal groove,
The lower end surface of second sealing ring and installation convex edge is fitted close.
Preferably, the lower end surface of the hex nut body is equipped with third sealing ring, the third sealing ring is located at pad
In the inner ring of circle.
Preferably, the cross sectional shape of the shield is circle, diameter of a circle is greater than six where the shield section
The length of angle nut body diagonal cross section, the top of the shield are equipped with block cover, and the shape of the block cover is hemispherical.
Preferably, the two sides of the washer are symmetrically arranged with guide pad, the side wall of the annular mounting groove is offered and is led
The guiding slot matched to block, the guiding slot run through the side wall of hex nut body.
The utility model has the beneficial effects that the utility model is by tying hex nut body, washer, spring and shield etc.
It is combined use, by the way that the structure of multiple sealing rings is arranged on shield and nut body, can effectively be improved whole
Leakproofness effectively avoids the problem that nut gets rusty, and the cooperation of spring and washer can be improved between nut and bolt
Pretightning force, while anti-slop serrations are set in the bottom of gasket, the frictional force being capable of increasing between workpiece and washer reaches locking mesh
's.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
