Abstract
The present invention provides a kind of Novel threaded anti-loose structure, including bolt, nut is rotary with bolt, the bottom of nut is provided with stop nut, stop nut includes half-nut I and half-nut II, the inner side of half-nut I and half-nut II has the screw thread that is engaged with bolt, has at least one pair of screwed hole on two opposite faces of half-nut I and half-nut II, has the screw that half-nut I and half-nut II are connected as to a nut in screwed hole.The present invention can effectively prevent thread looseness, improve threaded connection reliability, can't destroy bolt arrangement, reduce intensity.
Description
Technical field
The present invention relates to a kind of Novel threaded anti-loose structure, belongs to machine-building art field.
Background technology
Because locking thread is unreliable in plant equipment, cause mechanical accident countless, especially in the speed of service
It is high, impact is big, vibrations are strong, easily causes bolt, nut loosening or comes off, often lead to unreliable equipment work, damage or safety
Accident.It is more than or equal to M30 for the diameter of thread, the locking locking occasion of mode of the tradition such as split pin, flanging pad should not be used, needed
Design a kind of new locking mode.
The content of the invention
The present invention provides a kind of stop nut of new structure, to solve the problems, such as that prior art is present.
The present invention uses following technical scheme:
A kind of Novel threaded anti-loose structure, including bolt 1, nut 4 are rotary with bolt 1, the bottom of nut 4 is provided with locking spiral shell
Mother, stop nut include half-nut I 1 and half-nut II 3, and the inner side of half-nut I 1 and half-nut II 3 has to be engaged with bolt 1
Screw thread, have at least one pair of screwed hole on two opposite faces of half-nut I 1 and half-nut II 3, having in screwed hole will
Half-nut I 1 and half-nut II 3 are connected as the screw 2 of a nut.
The internal diameter for the stop nut that the half-nut I 1 connected by screw 2 and half-nut II 3 are formed is less than bolt 1
Internal diameter.
Beneficial effects of the present invention:The present invention can effectively prevent thread looseness, improve threaded connection reliability, can't
Bolt arrangement is destroyed, reduces intensity.
Brief description of the drawings
Fig. 1 is the connection diagram of the present invention.
Fig. 2 loosens nut schematic diagram for the present invention's.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
The present invention is by nut, bolt-connection characteristic analysis, by eliminating fit clearance between nut, bolt, improving pre-
Clamp force, enhancing nut, the reliability of bolt-connection.
Specifically, as shown in figure 1, the threaded anti-loosing structure of the present invention, including bolt 1, nut 4, spiral shell are rotary with bolt 1
The bottom of mother 4 is provided with the stop nut for preventing that nut 4 from loosening, and stop nut includes half-nut I 1 and half-nut II 3, half-nut
I 1 and the inner side of half-nut II 3 there is screw thread identical screw thread with the outside of bolt 1, two of half-nut I 1 and half-nut II 3
At least one pair of screwed hole is had on opposite face, has in screwed hole and half-nut I 1 and half-nut II 3 is connected as a spiral shell
Female screw 2.After bolts and nuts connect, half-nut I 1 and the spiral-lock of half-nut II 3 are leaned on bolt, and with nut
Tightly, then the screw 2 on opposite face is uniformly tightened.
The internal diameter for the stop nut that the half-nut I 1 and half-nut II 3 connected by screw 2 is formed is less than in bolt 1
Footpath, half-nut Light deformation can be made after mounting, fastened on bolt, eliminated the gap between half-nut and bolt, prevent spiral shell
Female and bolt looseness.The pretightning force between nut and bolt can be improved, prevents from loosening.
The present invention procedure of processing be:
Step 1:The nut of processing screw thread identical with bolt, and nut is processed into two half-nuts, have 2~3 between two half-nuts
Millimeter gap, symmetrical machining is no less than two screwed holes on half-nut as shown in Figure 1.
Step 2:By two halves nut buckle on the bolt of institute's stop nut, and it is close to nut.
Step 3:With the half-nut of screw attachment two, and tighten.
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
