Description
Technical field
This utility model relates to nut technical field, is specifically related to a kind of new type auto locking nut.
Background technology
In the prior art, self-locking nut has been widely used in fastener areas with the connection of bolt.At present
Self-locking nut be typically to be provided with the annular extension of protrusion in one end of plain nut, in the inside of extension
Having dug mosaic groove, nylon washer is fixed in mosaic groove, during assembling, because of bolt external screw thread large diameter-ratio Buddhist nun
Dragon aperture is big, can apply radial deformation pressure to nylon washer by screw thread during nylon cushion collar aperture, allow it produce
Radially micro-deformation, makes nylon washer produce deformation and reaches oneself's locking.
Actually used this self-locking nut when, because nylon washer smoother, frictional force is little, and
With contacting often because the careless mistake of processing method causes not having each other of the nut body of surrounding or extension
Fit completely, there is gap, therefore often it may happen that nylon washer spins, assembles difficulty situation, more
It is likely to result in nylon washer be ejected or come off, occurs to connect the situation loosening and losing efficacy.
Summary of the invention
The deficiency existed for prior art, the purpose of this utility model be to provide a kind of reasonable in design,
Simple in construction, easy to assembly, connect reliable, anti-loosing effect is good, the new type auto locking screw of length in service life
Female.
For achieving the above object, this utility model provides following technical scheme: a kind of new type auto locking screw
Mother, including nut body, the middle part of described nut body is provided with screwed hole, fixes setting in described screwed hole
It is equipped with a rubber positioning sleeve, the internal face of described rubber positioning sleeve has been wholely set multiple positioning convex,
And multiple positioning convex annular is uniformly distributed；A connecting screw hole it is provided with on the side of described nut body,
Being provided with spanner at described connecting screw hole, described spanner the inner has been wholely set one and described connecting screw hole
The connection screw rod joined, spanner by connect screw rod threaded with connecting screw hole, described spanner outer end integrally sets
Being equipped with a bulge loop, described bulge loop connects steel cable.
By using technique scheme, after arranging rubber positioning sleeve in nut body, when precession, rubber
Positioning convex in positioning sleeve is spacing with the external screw thread clamping on existing shank of bolt, and rubber positioning sleeve is in rotation
Compressed after crimp during entering, it is possible to play the effect of auto lock, easy to use；And spanner sets
Put rationally, be convenient to mount and dismount, and can be interconnected with neighbouring nut by steel wire rope, play locking slip-off preventing
Effect, reasonable in design, simple in construction, easy to assembly, connect reliable, anti-loosing effect is good, use
Life-span is long.
This utility model is further arranged to: the thickness of described rubber positioning sleeve is 0.6-1.2mm, described location
Projection is all in positive rectangular pyramid structure.By this setting, the thickness of rubber positioning sleeve arranges rationally, positioning convex
Structure arranges rationally, good positioning effect.
This utility model is further arranged to: the width of described rubber positioning sleeve is 2-4mm.By originally setting
Putting, rubber positioning sleeve width arranges rationally, and low cost of manufacture is easy to connect with screwed hole.
This utility model is further arranged to: described rubber positioning sleeve and the screwed hole internal face of nut body
Threaded or be adhesively fixed.By this setting, rubber positioning sleeve is fixing reliable.
This utility model is further arranged to: be bonded with caoutchouc elasticity circle on the inner face of described nut body,
And the aperture of caoutchouc elasticity circle is more than the aperture of screwed hole.By this setting, caoutchouc elasticity circle arranges rationally,
Nut is fixed relatively reliable.
The utility model has the advantages that: compared with prior art, this utility model structure arranges more reasonable,
After rubber positioning sleeve is set in nut body, when precession, the positioning convex in rubber positioning sleeve and existing spiral shell
External screw thread clamping on tightening latch is spacing, and rubber positioning sleeve is compressed after crimp during precession,
The effect of auto lock can be played, easy to use；And spanner is arranged rationally, it is convenient to mount and dismount, and can pass through
Steel wire rope interconnects with neighbouring nut, plays the effect of locking slip-off preventing, reasonable in design, structure
Simply, easy to assembly, connect reliable, anti-loosing effect is good, service life is long.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Seeing Fig. 1, a kind of new type auto locking nut disclosed in this utility model, including nut body 1, institute
The middle part stating nut body 1 is provided with screwed hole 11, is fixedly installed a rubber fixed in described screwed hole 11
Position set 2, the internal face of described rubber positioning sleeve 2 has been wholely set multiple positioning convex 21, and multiple fixed
Protruding 21 annulars in position are uniformly distributed；A connecting screw hole 12, institute it is provided with on the side of described nut body 1
Stating and be provided with spanner 3 at connecting screw hole 12, described spanner 3 the inner has been wholely set one and has been connected spiral shell with described
Hole 12 coupling connection screw rod 31, spanner 3 by connect screw rod 31 threaded with connecting screw hole 12, institute
