Description
Technical field
The utility model belongs to self-locking nut field, and in particular to a kind of stop nut structure.
Background technique
Apply must firm thread technology be that the tooth bottom of negative thread (also known as interior triangular screw thread, i.e. nut thread) is provided with one
A 30 ° of tapered ramp, when bolts and nuts are mutually tightened, the external screw thread cusp of standard bolt just tightly withstands on negative thread
Tapered ramp on, generate screw thread interference locking to increasing coupling mechanism force to realize screw thread self-locking.
With the development of economic technology, requirement of the structure being fastenedly connected to screw thread self-locking ability is gradually increased, and is only adopted
With it is above-mentioned apply must firm screw thread be no longer satisfied actual needs.
Application No. is the Chinese utility model patents of CN201720788045.9 to disclose a kind of nut side band wedge block
The anti-loose anti-theft nut of external member, the anti-loose anti-theft nut include the nut body with internal thread hole, and the side of nut body is opened
Equipped with slot, the side of nut body is run through in the left and right ends of slot, and wedge block is embedded in slot, and the inside of wedge block is abutted in interior
The external screw thread of bolt in threaded hole.
The nut utilizes wedge block puller bolt, to must further increase nut and bolt on the basis of firm screw thread applying
Coupling mechanism force before.But disadvantage is that: wedge block is embedded on the outside of the nut body, this allows for wedge block to setting
The resistance of standby transverse vibration is poor, and when violent transverse vibration occurs for equipment, wedge block easily falls off from slot, causes to lock
Tight failure.
Utility model content
Present invention purpose is to provide a kind of stronger stop nut structure of lock ability.
For achieving the above object, the technical solution of the application is as follows:
A kind of stop nut structure, including nut body, the interior internal thread hole with for installing bolt of the nut body,
Annular groove is offered on the inner wall of the internal thread hole, is offered on the nut body and is extended to from the outside of nut body
Annular groove runs through threaded hole, and the lock-screw for puller bolt should be equipped in threaded hole.
The application opens up annular groove on the inner wall of nut body, and sets up in the week of annular groove through threaded hole,
By in the installation locking screw in the threaded hole, lock-screw gradually screw in can puller bolt external screw thread, to increase
Coupling mechanism force of the strong nut body to bolt.
It is described to have at least two through threaded hole in above-mentioned stop nut structure, it is all circumferential through threaded hole
It is uniformly arranged on nut body.The multiple threaded holes that run through being arranged in annular groove circumferential direction can be in the circumferentially upper shape of nut body
The coupling mechanism force of pairs of bolt, it is ensured that the coupling mechanism force is stablized.
In above-mentioned stop nut structure, the nut body is hex nut, and described has three through threaded hole
It is a.
In above-mentioned stop nut structure, described is arranged in a mutually vertical manner through threaded hole with internal thread hole.
In above-mentioned stop nut structure, the bolt penetrating end of the nut body is equipped with counterbore, the counterbore it is interior
Diameter is greater than the internal diameter of internal thread hole, is fixedly installed nylon ring in the counterbore.Nylon ring can form third road to bolt
Coupling mechanism force.
In above-mentioned stop nut structure, the bolt penetrating end of the nut body is had for limiting nylon ring position
The in-flanges set.Although nylon ring is firmly adhered in counterbore, nylon ring further can be limited in counterbore by in-flanges
Interior, avoiding the adhesion strength between nylon ring and counterbore inner wall from being destroyed causes nylon ring to fall off.
Compared with prior art, the utility model has the following beneficial effects:
The application opens up annular groove on the inner wall of nut body, and sets up in the week of annular groove through threaded hole,
By in the installation locking screw in the threaded hole, lock-screw gradually screw in can puller bolt external screw thread, to increase
Coupling mechanism force of the strong nut body to bolt.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of stop nut structure of the utility model；
Fig. 2 is a kind of cross-sectional view of stop nut structure of the utility model.
Specific embodiment
The technical solution of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment 1
As depicted in figs. 1 and 2, a kind of stop nut structure of the present embodiment, including nut body 1, band in the nut body 1
There is the internal thread hole 11 for installing bolt 2.
As shown in Figure 2, in conjunction with Fig. 1 as it can be seen that the bolt penetrating end of nut body 1 is equipped with counterbore 12, counterbore 12 is interior to be equipped with Buddhist nun
Dragon circle 3, the internal diameter of the counterbore 12 is greater than the internal diameter of internal thread hole 11, therefore nylon ring 3 can be against on the bottom surface of counterbore 12.Buddhist nun
Dragon circle 3 can form tension force around bolt 2, to firmly hold bolt 2 tightly, increase nut to the coupling mechanism force of bolt 2.
The fixation that both can be realized by means such as adhesives between nylon ring 3 and counterbore 12, additionally can be
In-flanges 13 is added on the end face of 2 penetrating end of bolt of nut body 1, to limit 3 forming position of nylon ring.
As depicted in figs. 1 and 2, it is offered on the middle-end of nut body 1 or bolt traversing through end, the inner wall of internal thread hole 11
Annular groove 14, offer on nut body 1 extended to from the outside of nut body 1 annular groove 14 several through threaded hole 15,
It is arranged in a mutually vertical manner through threaded hole 15 and internal thread hole 11, is each mounted in threaded hole 15 for puller bolt 2
Lock-screw 4.
By in the installation locking screw 4 in the threaded hole 15, lock-screw 4 gradually screws in can puller bolt 2
External screw thread, to enhance nut body 1 to the coupling mechanism force of bolt 2.
Multiple threaded holes 15 that run through should be circumferentially uniformly arranged on nut body 1, to ensure that nut body 1 is each
Coupling mechanism force in circumferential direction is consistent, it is ensured that locking is firm.The nut body 1 of the present embodiment is hex nut, and in hexagonal spiral shell
Three have been uniformly arranged on mother through threaded hole 15.
The groove width of annular groove 14 can be consistent with through the internal diameter of threaded hole 15, can also be than in threaded hole 15
Diameter is slightly larger.
A kind of working principle of stop nut structure of the present embodiment are as follows:
First nylon ring 3 is embedded in counterbore 12, it is correct to assemble；Then bolt 2 is penetrated again, after bolt 2 is installed in place, is being passed through
Installation locking screw 4 in threaded hole 15 is worn, until the end face of lock-screw 4 is resisted against on the external screw thread of bolt 2.
