Description
Technical field
The invention belongs to machanical fastener field, and in particular to a kind of stop nut.
Background technology
Nut is widely used in various plant equipment, its operation principle is to use as a kind of common component of machine
Frictional force between nuts and bolt carries out self-locking.But the reliability of this self-locking will reduce in dynamic loading.It is anti-
The only loosening of nut, often in some special occasions, we will take some locking measures, ensure the reliability of nut check.
It is exactly a kind of locking measures therein wherein with locking nut.
At present, common anti-loose method has：
Rub locking：Including spring washer is locking, double nut is locking, self-locking nut is locking, elastic ring nut anti-looseness etc.；
Dismounting of this locking mode for nut is more convenient, but in the case of shock and vibration and varying load, easily releases, spiral shell
Line connection failure.
Machinery is locking：Including slotted nut and split pin nut anti-looseness, round nut are locking, locked spacer is locking, series connection steel
Silk is locking etc.；This mode causes dismounting inconvenient.
Riveting is rushed locking：Including trimming method is locking, bonding is locking etc.；The shortcomings that this mode is that screw rod is used only once,
And dismounting is very difficult, it is necessary to which destroying bolt pair can dismantle.
Structure is locking：Screw thread pair self structure is locking.This mode can be dismantled repeatedly, and anti-loosening property is good, but require
It is special, processing difficulties.
The content of the invention
It is an object of the invention to：Propose a kind of stop nut, with realize it is vibrated, impact when, nut is not easy
Voluntarily released along the screw thread on bolt or screw rod.
In order to solve the above technical problems, present invention employs following technical scheme：
A kind of stop nut, including nut body 1 and lock-screw 2, the cylinder of nut body 1 are provided perpendicular to axial
Locking slot 11, the end face center of nut body 1 are provided with tapped through hole 12, are provided with by tapped through hole 12 and match with lock-screw 2
The locking screw pit 13 of conjunction, locking screw pit are included in the counter sink 14 coaxial with locking screw pit of upper surface, nut body 1
Including upper surface and lower surface, the nut body 1 between upper surface and groove 11 is body upper part 15, and top wall thickness is nut sheet
1.5~2 times of the pitch of body screwed hole of centre 12,0.25~0.3 times of a diameter of nut body screwed hole of centre of locking screw pit.
Preferably, the tapped through hole 12 is parallel with the axle of locking screw pit 13.
Preferably, 0.5-0.75 times that groove depth is nut diameter is locked.
Preferably, the locking slot 11 is symmetrical relative to locking screw pit 13.
Preferably, the nut body 1 is sides nut.
Preferably, the nut body 1 is six square nuts.
Preferably, the nut body 1 is slotted round nut.
Preferably, the nut body 1 is round nut.
The beneficial effects of the present invention are：Combined using nut body 1 with the connection of lock-screw 2, it is locking to reach locking
Effect, specifically have it is following some：1. nut lock clamp force is parallel with screw thread Impact direction, field of load is threadedly coupled in locking nut
Interior, screw thread stress is bigger, and locking effect is better.2. simple in construction, installation and removal are convenient and swift, repeat and utilize.It is 3. described
Locking nut can reach locking anti-loosing effect in optional position on bolt or screw rod.

Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that institute
The embodiment of description is only part of the embodiment of the present invention, rather than whole embodiments.
Embodiment 1：Fig. 1 is that a kind of stop nut structure disassembles schematic diagram, and Fig. 2 is nut body top view, and Fig. 3 is nut
Body A-A sectional views.A kind of stop nut, including the word lock-screw 2 of six square nuts body 1 and one, the material of six square nuts body 1
For No. 45 steel or 30CrMnSi, quenching hardness is HRC35~40, and center screw thread is M16 × 2, and its cylinder is provided perpendicular to axle
To locking slot 11, the end face center of six square nuts body 1 is provided with tapped through hole 12, is provided with by tapped through hole 12 and a letter lock
The locking screw pit 13 that tight screw 2 is engaged, locking screw pit are included in the counter sink coaxial with locking screw pit of upper surface
14, six square nuts body 1 includes upper surface and lower surface, and the six square nuts body 1 between upper surface and groove 11 is on body
Portion 15, nut top 3~4mm of wall thickness, locking screw pit M4, tapped through hole is parallel with the axle of locking screw pit, locks groove depth
Spend for 0.5 times of nut diameter, locking slot is symmetrical relative to locking screw pit.
Embodiment 2：As shown in figure 4, six square nuts are sides nut in embodiment 1.
