Description
【Technical field】
The utility model is related to the technical fields of the technical field of fastener, especially nut.
【Background technology】
Nut is a kind of common part, is widely used in the fields such as manufacture, machinery.Existing nut is after tightening
Loosening is easy tod produce in use so that the structure that nut is fastened becomes to loosen so that mechanism can not be transported normally
Sometimes even therefore accident can occur for row.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of steady nut, can
Nut is set to be not easy to loosen.
To achieve the above object, the utility model proposes a kind of steady nut, including main column, auxiliary rod,
Tighten lid, the main column center sets that there are one main thread holes, and main column is by the first cylinder and second on same axis
Cylinder forms, and the first cylinder is fixed on the upper end of the second cylinder, and the first main body is cylinder, and the second cylinder is in regular hexagonal prism shape,
First cylinder top is equipped with one section of first external screw thread, tightens in lid and is equipped with and spiral shell in the first external screw thread matched first
Line is tightened lid and is screwed on the first cylinder, tightens base portion and fixes there are one subring, subring inside is described in truncated cone
First column side wall is equipped with several through-holes for running through the first main body wall, is plugged with an auxiliary rod in through-hole, auxiliary rod it is outer
End is an inclined-plane, and the inclined-plane of auxiliary rod outer end mutually agrees with the inner wall of subring.
Preferably, the tightening direction of first internal thread is opposite with the tightening direction in main thread hole.
Preferably, described tighten is opened up at the top of lid there are one via hole, the internal diameter of via hole is more than main thread hole
Internal diameter.
Preferably, the through-hole rectangular in cross-section, through-hole is vertical with main thread hole and is directed toward the axis in main thread hole.
Preferably, the inner end of the auxiliary rod is fixed with one piece of elastomer block.
The beneficial effects of the utility model：The utility model is by matching auxiliary rod with subring so that after tightening
Main column screw on tighten lid after auxiliary rod screw thread can be blocked, be not easy to loosen；The setting of elastomer block makes auxiliary rod can be more
Good blocks screw thread, and is hardly damaged screw thread；The setting of second cylinder makes main column be easy to be tightened.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
【Description of the drawings】
Fig. 1 is a kind of front view of steady nut of the utility model.
In figure：1- main columns, 2- tighten lid, 3- auxiliary rods, 10- main threads hole, the first cylinders of 11-, the second cylinders of 12-,
The first external screw threads of 13-, 20- via holes, 21- subrings, the first internal threads of 23-, 30- through-holes, 31- elastomer blocks.
【Specific implementation mode】
Refering to fig. 1, a kind of steady nut of the utility model, including main column 1, auxiliary rod 3, lid 2 is tightened, it is described
1 center of main column is set there are one main thread hole 10, and main column 1 is by the first cylinder 11 and the second cylinder 12 on same axis
Composition, the first cylinder 11 are fixed on the upper end of the second cylinder 12, and the first main body is cylinder, and the second cylinder 12 is in regular hexagonal prism
Shape, 11 top of the first cylinder are equipped with one section of first external screw thread 13, tighten in lid 2 equipped with matched with the first external screw thread 13
First internal thread 23 is tightened lid 2 and is screwed on the first cylinder 11, tightens 2 bottom of lid and fixes there are one subring 21, in subring 21
Side is in truncated cone, and 11 side wall of the first cylinder is equipped with several through-holes 30 for running through the first main body wall, is filled in through-hole 30
There is an auxiliary rod 3, the outer end of auxiliary rod 3 is an inclined-plane, the inclined-plane of 3 outer end of auxiliary rod and the inner wall phase contract of subring 21
It closes, the tightening direction of first internal thread 23 is with the tightening direction in main thread hole 10 on the contrary, the top for tightening lid 2 opens up
There are one via hole 20, the internal diameter of via hole 20 is more than the internal diameter in main thread hole 10,30 rectangular in cross-section of the through-hole, through-hole 30
Axis that is vertical with main thread hole 10 and being directed toward main thread hole 10, the inner end of the auxiliary rod 3 is fixed with one piece of elastomer block 31.
Utility model works process：
During the work time, auxiliary rod 3 matches a kind of steady nut of the utility model with subring 21 so that
Main column 1 after tightening screw on tighten lid 2 after auxiliary rod 3 screw thread can be blocked, be not easy to loosen；The setting of elastomer block 31 makes
Auxiliary rod 3 can preferably block screw thread, and be hardly damaged screw thread；The setting of second cylinder 12 makes main column 1 be easy to be tightened.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, any new to this practicality
Scheme after type simple transformation belongs to the scope of protection of the utility model.
