Abstract
The utility model discloses a kind of nut assemblies for locking fastening, including polygonal nut, polygonal nut inner wall one end offers screw thread, the polygonal nut inner wall other end is shiny surface, it further include interior round nut, inner circle nut inner wall offers screw thread, and inner circle nut outer wall is shiny surface, and interior round nut one end can be embedded in one end of the shiny surface of polygonal nut；By two nut mating reactions, the loosening of nut can be effectively prevented, the safety of production is improved, to mitigate the work load of staff.
Description
Technical field
The utility model belongs to accessory tool technical field, and in particular to a kind of nut assembly for locking fastening.
Background technology
It is more universal in the use of field of coal mining, various big machineries, the safety of big machinery operation extremely closes weight
It wants.In order to prevent since vibrations cause the generation of nut loosening phenomenon, staff to be required for a cable daily in mechanical movement
Slot connecting plate (clamping plate) nut fastens one time, needs to consume a large amount of time；And there are cable trough connecting plates (clamping plate) to fall off
Possibility, such case very likely causes chain rupture accident, strong influence normally to produce.
Utility model content
The purpose of this utility model is to provide a kind of nut assemblies for locking fastening, can effectively prevent nut
Loosening, improve the safety of production.
The technical solution adopted in the utility model is a kind of nut assembly for locking fastening, including polygonal nut, more
Angle nut inner wall one end offers screw thread, and the polygonal nut inner wall other end is shiny surface, further includes interior round nut, interior round nut
Inner wall offers screw thread, and inner circle nut outer wall is shiny surface, and interior round nut one end can be embedded in the one of the shiny surface of polygonal nut
End.
The utility model is also characterized by：
The polygonal nut axis direction of outer wall vertical of polygonal nut offers threaded hole, and miniature spiral shell is provided in threaded hole
Nail, miniature screw thread can pass through polygonal nut.
The outer wall of interior round nut offers multiple grooves along interior round nut length direction, and the width of groove is more than miniature screw thread
Diameter.
Interior round nut uniformly successively decreases with the mutually embedding one end outer wall thickness of polygonal nut, and polygonal nut inner wall is one end of shiny surface
Outer wall thickness uniformly successively decreases.
Interior round nut maximum outside diameter is more than the maximum inner diameter of polygonal nut.
A kind of nut assembly advantageous effect for locking fastening of the utility model is：By two nut mating reactions,
The loosening that nut can effectively be prevented, improves the safety of production, to mitigate the work load of staff.
Description of the drawings
Fig. 1 is a kind of nut assembly structural schematic diagram for locking fastening of the utility model.
In figure, 1. polygonal nuts, round nut in 2., 3. threaded holes, 4. miniature screw threads, 5. grooves.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of nut assembly for locking fastening of the utility model, as shown in Figure 1, including polygonal nut 1, polygonal nut
1 inner wall one end offers screw thread, and the 1 inner wall other end of polygonal nut is shiny surface, further includes interior round nut 2, in interior round nut 2
Wall offers screw thread, and 2 outer wall of interior round nut is shiny surface, and 2 one end of interior round nut can be embedded in the one of the shiny surface of polygonal nut 1
End.
Polygonal 1 axis direction of nut of outer wall vertical of polygonal nut 1 offers threaded hole 3, is provided in threaded hole 3 miniature
Screw 4, miniature screw thread 4 can pass through polygonal nut 1.
The outer wall of interior round nut 2 offers multiple grooves 5 along 2 length direction of interior round nut, and the width of groove 5 is more than miniature
The diameter of screw 4 enables in 4 deep enough groove 5 of miniature screw thread.
Interior round nut 2 uniformly successively decreases with 1 mutually embedding one end outer wall thickness of polygonal nut, and 1 inner wall of polygonal nut is shiny surface
One end outer wall thickness uniformly successively decreases.
2 maximum outside diameter of interior round nut is more than the maximum inner diameter of polygonal nut 1.
A kind of application method of nut assembly for locking fastening of the utility model is as follows：
When installation, polygonal nut 1 is fixed on screw, then interior round nut 2 is screwed on same screw, and is embedded
In polygonal nut 1, miniature screw thread 4 is turned, miniature screw thread 4 is made to stretch in groove 5, completes the fixation of nut assembly at this time.
When dismounting, miniature screw thread 4 is turned, so that miniature screw thread 4 is detached from groove 5, then back-outs interior round nut 2, then turn
Polygonal nut 1 completes the dismounting of nut assembly.
By the above-mentioned means, a kind of nut assembly for locking fastening of the utility model, by two nuts with cooperation
With can effectively prevent the loosening of nut, improve the safety of production, to mitigate the work load of staff.
