Abstract
The invention discloses a nut for locking operation. The nut comprises a flange and a bolt matched with the flange. The bolt is sleeved with a circular nut body. Small threaded holes are evenly distributed on the periphery of a threaded hole of the circular nut body. Screws are installed in the small threaded holes. A spanner rotation hole is formed in the outer wall of the circular nut body in the radial direction. The nut is simple in structure and convenient to operate; and the requirement for the pre-tightening force can be met only through a small-torque spanner, and meanwhile equipment overhaul time can be greatly shortened.
Description
Technical field
The present invention relates to technical field of mechanical transmission, specifically refer to a kind of locking nut.
Background technique
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 large screw-down torque in the process of tightening, some needs the spanner being equipped with large size, some strength by a people cannot reach, and needs to knock with hammer, or many people come afterburning with extension lever, or even use dedicated hydraulic spanner, some by adding thermal expansion to reach, so just will add manpower, the cost of material resources especially virtually.
Therefore, research and develop a kind of structure simple, operate locking nut easily and seem very necessary.
Summary of the invention
Object of the present invention to provide exactly a kind of structure simple, operate locking nut easily, only need little torque spanner just can reach the requirement of pretightening force by this device, while can greatly reduce time of overhaul of the equipments.
For achieving the above object, locking nut designed by the present invention, the bolt comprise flange, coordinating with flange, bolt is arranged with round nut, the tapped hole periphery of round nut has been evenly arranged minor thread hole, minor thread is provided with screw in hole, the outer wall of round nut has been disposed radially spanner rotating hole.
Preferably, the tapped hole periphery of round nut has been evenly arranged five minor thread holes, and screw is supported on hard gasket.
Further, hard gasket is provided with between flange and round nut.
Advantage of the present invention is mainly reflected in following several respects:
One, structure is simple, operation is convenient;
Its two, only need little torque spanner just can reach the requirement of pretightening force, the time of overhaul of the equipments can be greatly reduced simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 present invention is described in further detail, but this embodiment should not be construed limitation of the present invention.
Locking nut shown in figure, the bolt 5 comprise flange 4, coordinating with flange 4, bolt 5 is arranged with round nut 1, and the tapped 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 tapped hole periphery of round nut 1 has been evenly arranged five minor thread holes.
Be provided with hard gasket 2 between flange 4 and round nut 1, screw 3 is supported on hard gasket 2.
When the present invention works, bolt 5 inserts flange 4 through round nut 1, inserts spanner rotating hole 6 and is tightened by round nut 1, then be contained in by screw 3 in the minor thread hole on nut 1 with spanner, twisting screw 3 compresses the hard gasket 2 below round nut 1, makes bolt 5 reach pretightening force requirement.
The content be not described in detail in this specification, belongs to the known prior art of those skilled in the art.
