Embodiment 1

[0015] Embodiment 1: as figure 1 , figure 2 As shown, design and manufacture a hexagonal nut with a sealing ring, including a nut body 1, a screw hole 4 is provided in the center of the nut body 1, and an internal thread is provided in the screw hole 4. The main features of the present invention are: the outer side of the screw hole 4 The nut end face 5 is provided with an inner annular groove 6 and an outer annular groove 2 with the same axis, and an inner sealing ring 7 and an outer sealing ring are respectively provided in the inner annular groove 6 and the outer annular groove 2 3. The height dimension of the inner sealing ring 7 and the outer sealing ring 3 is the same, but both are greater than the depth dimension of the groove bottom of the inner annular groove 6 and the groove bottom of the outer annular groove 2.

[0016] The material of the nut body 1 is a magnet-absorbing material, and the materials of the inner sealing ring 7 and the outer sealing ring 3 are rubb...

Abstract

The invention discloses a hexagonal nut with seal rings. A nut end face outside a screw hole is provided with an inner circular groove and an outer circular groove, the inner circular groove and the outer circular groove are axially identical, an inner seal ring and an outer seal ring are arranged in the inner circular groove and the outer circular groove respectively, and heights of the inner seal ring and the outer seal ring are equal and larger than depths of the bottoms of the inner circular groove and the outer circular groove. A nut body is made from a magnet attracting iron material, the inner seal ring and the outer seal ring are rubber soft magnets, and magnetic surfaces of the inner seal ring and the outer seal ring are positioned upwards to enable the inner seal ring and the outer seal ring to be attracted in the inner circular groove and the outer circular groove respectively under the magnetic action. The hexagonal nut with the seal rings has the advantages that excellent sealing effects are achieved since deflection and deformation of the seal rings are prevented, and the seal rings are protected from being lost resulted from shedding from a screw rod.

Description

technical field [0001] The invention relates to the technical field of hexagonal nuts, in particular to a hexagonal nut with a sealing ring. Background technique [0002] When using a hexagonal nut to cooperate with a screw rod to fasten a container for storing liquid, a sealing ring needs to be set on the screw rod in front of the hexagonal nut. There are two disadvantages in this method of operation: one is that when the hexagon nut is tightened, it is easily dislocated and deformed by the rotation and extrusion of the hexagon nut, which seriously affects the sealing effect; the other is that when the hexagon nut is removed, it is easy to fall off from the screw rod, lost. Contents of the invention [0003] The problem to be solved by the present invention lies in the deficiencies in the prior art. It provides a hexagonal nut, which can prevent misalignment and deformation of the sealing ring, achieve a good sealing effect, and prevent the sealing ring from falling off ...
