Description
Technical field
The utility model relates to technical field of engineering machinery, specially a kind of stop nut.
Background technique
Threaded connection be it is a kind of it is widely used removably is fixedly connected, have structure is simple, connection reliably, assembly and disassembly side
Just the advantages that.In real work, external applied load has vibration, variation, material at high temperature creep etc. to will cause frictional force reduction, in screw thread pair
Normal pressure loosens, such as through repeated action, threaded connection will in a certain pop-off, frictional force zero to make to be threadedly coupled
Loose and fail, nut will fall off.Therefore, it is necessary to it is locking to nut progress, it otherwise will affect normal work, cause the accident.
Presently, there are a kind of stop nuts to drill at the screw thread of nut end face, and pin shaft, pin shaft and through-hole are inserted into through-hole
Interference fit.Although the stop nut plays a role to the loosening of threaded connection, the pin shaft squeezed into can destroy original
There is screw thread, dismounting is inconvenient, secondary cannot use.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of stop nut, it fine can obtain and screw connection structure is risen
To locking effect, can repeated removal, good reliability.
Its technical solution is such that a kind of stop nut, including nut body, the nut body are equipped with inner hole, institute
Inner hole is stated equipped with screw thread, which is characterized in that the outer surface of the nut body is equipped with stage portion, and the stage portion is equipped with
The upper end of threaded hole, the stage portion is equipped with male cone (strobilus masculinus), further includes a pressure ring, the inner hole of the pressure ring is set as and the nut
The internal taper hole that male cone (strobilus masculinus) on ontology matches, the threaded hole corresponded on the pressure ring in the stage portion are equipped with screw hole, tightly
Determine screw and sequentially passes through the screw hole and the threaded hole for the pressure ring and nut body locking.
Further, the quantity of the screw hole and the threaded hole is the even number being respectively greater than equal to 4.
Further, symmetrically arranged round tube hole there are two being set in the stage portion.
Further, the screw hole includes thread segment and the nut counterbore that is arranged on thread segment.
Further, the surface roughness of the internal taper hole and the male cone (strobilus masculinus) is not less than Ra1.6 respectively.
Further, the inner hole of the nut body and the male cone (strobilus masculinus) form thin-wall part.
Further, radially through groove is provided in the inner hole of the nut body.
The stop nut of the utility model, structurally reasonable, the male cone (strobilus masculinus) on internal taper hole and nut body on pressing plate is matched
It closes, under the responsive to axial force of holding screw and pressing plate, the center of active force is overlapped with the center for being threadedly coupled active force, uniformly
It shrinks and is pressed on the thread spindle of stop nut installation, the loosening of nut body can be effectively prevented, threaded connection can be played
Real anti-loose effect, and the stop nut is compact-sized, repeats disassembly, the component of easy maintenance and replacement damage.
Detailed description of the invention
Fig. 1 is the half sectional view of stop nut provided by the utility model；
Fig. 2 is the top view of stop nut provided by the utility model；
Fig. 3 is the top view of the nut body of another embodiment provided by the utility model.
Specific embodiment
See that Fig. 1, Fig. 2, Fig. 3, a kind of stop nut of the utility model, including nut body 1, nut body 1 are equipped with interior
Hole 11, inner hole 11 are equipped with screw thread, and nut body 1 and thread spindle 2 are threadedly engaged installation, and the outer surface of nut body 1 is equipped with
Stage portion 12, stage portion 12 are equipped with threaded hole 13, and it further includes a pressure ring 3, pressure ring that the upper end of stage portion 12, which is equipped with male cone (strobilus masculinus) 14,
3 inner hole is set as the internal taper hole 31 to match with the male cone (strobilus masculinus) 14 on nut body 1, and the spiral shell in stage portion is corresponded on pressure ring 3
Pit is equipped with screw hole 4, and screw hole 4 includes thread segment 41 and the nut counterbore 42 that is arranged on thread segment 41, holding screw 5 according to
It is secondary pass through screw hole 4 pressure ring 2 and nut body 1 are locked with threaded hole 13, set in stage portion 12 there are two symmetrically arranged circle
Through-hole 15, in the present embodiment, the quantity of screw hole 4 and threaded hole 13 is respectively 6, the surface of internal taper hole 31 and male cone (strobilus masculinus) 14
Roughness is not less than Ra1.6 respectively, and the inner hole 11 and male cone (strobilus masculinus) 14 of nut body form thin-wall part.
When the wall thickness between the inner hole 11 and male cone (strobilus masculinus) 14 of nut body is larger, to guarantee anti-loosing effect, nut body
Radially through groove 6 is provided in inner hole 11.
Nut body is screwedly mounted on by the stop nut of the utility model in use, first passing through two symmetrically arranged round tube holes
On thread spindle, then pressing plate is sleeved on nut body, the threaded hole being aligned on the screw hole and stage portion on pressure ring, clamp screw
Nail sequentially passes through screw hole and threaded hole and locks pressure ring and nut body, using even number holding screw by regulation screw-down torque
By pressing plate axial locking, male cone (strobilus masculinus) stepless action is acted in the center of active force on thread spindle and threaded connection on nut body
The center of power is overlapped, and can play to threaded connection really locking, and the stop nut is compact-sized, repeats disassembly, side
Just repair and replace the component of damage.
Above embodiments only express one of embodiment of the utility model, and the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
