Description
Technical field
The utility model relates to recoil inserts field more particularly to a kind of scratch resistant recoil inserts.
Background technique
Recoil inserts is to screw in simultaneously tight for the insert protecting non-ferrous metal threaded hole and developing suitable for being threadedly coupled
Gu forming standard female in the threaded hole of one of connected piece, bolt (or screw) is screwed into wherein again.With cold-rolling stainless steel
Line manufacture spiral inside and outside body helical coil, cross section with one heart assume diamond in shape, and shape is similar to helical spring, with higher hard
Degree and preferable surface roughness, recoil inserts are loaded in screw hole or nut, are had and are mitigated thread unbalance stress and shock resistance vibration
The fatigue strength of screw thread can be improved in dynamic effect, reduces abrasion and the corrosion resistance of screw thread, extends the screw hole service life.
Prior art discloses a kind of recoil inserts structure, (application number: 201110393580.1), which is related to one kind
Recoil inserts structure, the recoil inserts structure are the recoil inserts formed using coil along the hand of spiral, including both ends by
It is close thread segment that coil intensively forms, looser relative to the close thread segment by coil between the close thread segment in both ends
The loose thread segment formed, any one end of recoil inserts are equipped with introduction segment.The present invention passes through coil around to formation two
It, in loose thread segment, realizes when repairing of the structure in reinforcement or threaded hole for screw, obtains in close thread segment and centre in end
To play elastic abutting by the structure, to reach preferably locking and anti-loosing effect, while having effects that certain precompressed,
And by the way that introduction segment is arranged at one end, to reach rapid importing, accurate, simplicity and locking effect.
Although can be arrived using the patent to good anti-loosing effect, in actual use, recoil inserts and screw are being torn open
During dress, recoil inserts port can generate certain abrasion to screw, be easy to cause the damage of screw thread.
Summary of the invention
Shortcoming present in view of the above technology, the purpose of the utility model is to provide a kind of scratch resistant recoil inserts,
The device when in use, to screw thread cause to scratch by the port that can be effectively prevented from sheath ontology, prevents screw thread
Damage, and the structure is simple, production cost is low.
To achieve the above object, the utility model is realized in this way:
A kind of scratch resistant recoil inserts comprising the sheath ontology formed using coil along the hand of spiral, feature are existed
In described sheath ontology at least one end is provided with scraping prevention structure.At least one end of sheath ontology is provided with scraping prevention structure, benefit
Screw thread is caused to scratch with the port that the scraping prevention structure can be effectively prevented from sheath ontology, prevents the damage of screw thread
It is bad.
Further, the scraping prevention structure is scarf, and the scarf is arranged on the inside of the port of sheath ontology.The shield
The port of set ontology is set as scarf, and the scarf is towards the inside of sheath ontology, compared with existing plumb cut, energy
Effectively reduce abrasion of the port to screw thread of sheath ontology.
Further, the scraping prevention structure is linear introduction segment, and the introduction segment is arranged at the port of sheath ontology.
Linear introduction segment is set, when screw thread is screwed into introduction segment, introduction segment will avoid outward, at this point, sheath ontology
Port and screw thread can pull open certain evaded distance, avoid the friction of sheath ontology and screw thread, and then avoid protecting
Screw thread is caused to scratch the port of set ontology.
Further, a quarter of of length no more than sheath ontology individual pen of the linear introduction segment.The importing
The length of section is unsuitable too long, otherwise will affect the actual use of sheath ontology.
Further, the end that fractures is additionally provided at the port of the linear introduction segment, the end that fractures is arc, and is fractureed
End is consistent with the spiral winding set direction of sheath ontology, and the end that fractures is connected with the installing handle on sheath ontology.It is described to fracture
The setting at end, is connected convenient for introduction segment with installing handle, while being conducive to accurate removal installing handle, does not influence the rotation of screw thread
Enter, and the length at the end that fractures is also unsuitable too long, otherwise will affect the practical effect of linear introduction segment.Specifically, institute
State introduction segment production technology can be sheath ontology preparatory processing molding after, a part at port is further processed into directly
The introduction segment of wire type.
Further, the scraping prevention structure is evacuation protrusion, in evacuation protrusion is arranged at sheath ontology port
Side.The setting of the evacuation protrusion when making screw and evacuation projection contacts, can be avoided outward at the port of sheath ontology, be kept away
Exempt from port to be in contact with screw thread, and then avoids the scratch of screw thread；Specifically, the evacuation protrusion is sheath sheet
A certain section at body end mouth is recessed inwardly to be formed, this processing method is convenient for being applied in production technology.
Further, the scratch resistant mechanism is the loose fillet of screw, and the interior tooth diameter of the pine fillet of screw is relative in intermediate coil
Tooth diameter is big, and the port that can avoid sheath ontology mutually rubs with screw thread.The setting of the pine fillet of screw, so that screw thread is twisted
When entering sheath ontology, because the interior tooth diameter of the loose fillet of screw is larger, the loose fillet of screw is looser winding, can be generated with screw thread certain
Evaded distance, the friction of port and screw thread is avoided, to achieve the purpose that scratch resistant.
Further, the circle number of the loose fillet of screw is at least 1 circle.
The advantage of the utility model is, when the utility model is used, the port of sheath ontology can be effectively prevented from
Screw thread is caused to scratch, prevents the damage of screw thread, and the structure is simple, production cost is low.
