Abstract
The utility model discloses a nut is used in locking, including the flange, with flange complex bolt, the cover is equipped with the round nut on the bolt, little screw hole has evenly been arranged to the screw hole periphery of round nut, little threaded hole installs the screw, along radially being provided with the rotatory hole of spanner on the outer wall of round nut. The utility model discloses simple structure, operation facility, only need little moment spanner just can reach the requirement of pretightning force, the while can significantly reduce time of overhaul of the equipments.
Description
Technical field
The utility model relates to technical field of mechanical transmission, specifically refers to a kind of locking nut.
Background technology
Nut be screwed in bolt or screw rod together be used for the part that plays the role of fastening, be all manufacture machinery must a kind of element. In the work that we are usual, the nut exceeding certain specification needs very big screw-down torque in the process tightened, some needs the spanner being equipped with large size, some cannot be reached by the strength of a people, it is necessary to knocks with hammer, or many people come afterburning with boosting-rod, or even use dedicated hydraulic spanner, some to be reached by adding thermal expansion especially, is so just virtually adding manpower, the cost of material resources.
Therefore, a kind of structure of research and development simple, operate locking nut easily and seem very necessary.
Summary of the invention
The purpose of this utility model to be provided exactly a kind of structure simple, operate locking nut easily, only need little moment spanner just can reach the requirement of preliminary tension by this device, while can greatly reduce time of overhaul of the equipments.
For achieving the above object, locking nut designed by the utility model, comprise the bolt that flange coordinates with flange, bolt is arranged with round nut, the threaded hole periphery of round nut has been evenly arranged minor thread hole, minor thread is provided with screw in hole, and the outer wall of round nut has been disposed radially spanner rotating hole.
Preferably, the threaded hole periphery of round nut has been evenly arranged five minor thread holes, and screw is supported on hard gasket.
Further, hard gasket it is provided with between flange and round nut.
Advantage of the present utility model is mainly reflected in following several respects:
Its one, structure is simple, operation is convenient;
Its two, only need little moment spanner just can reach the requirement of preliminary tension, the time of overhaul of the equipments can be greatly reduced simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: round nut 1; Hard gasket 2; Screw 3; Flange 4; Bolt 5; Spanner rotating hole 6.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model.
Locking nut shown in figure, comprising the bolt 5 that flange 4 coordinates with flange 4, bolt 5 is arranged with round nut 1, the threaded hole periphery of round nut 1 has been evenly arranged minor thread hole, screw 3 is installed in minor thread hole, the outer wall of round nut 1 has been disposed radially spanner rotating hole 6.
The threaded hole periphery of round nut 1 has been evenly arranged five minor thread holes.
Being provided with hard gasket 2 between flange 4 and round nut 1, screw 3 is supported on hard gasket 2.
When the utility model works, bolt 5 inserts flange 4 through round nut 1, inserts spanner rotating hole 6 with spanner and is tightened by round nut 1, then is contained in the minor thread hole on nut 1 by screw 3, twisting screw 3 compresses the hard gasket 2 below round nut 1, makes bolt 5 reach preliminary tension requirement.
The content not being described in detail in this specification sheets, belongs to the known prior art of those skilled in the art.
