Description
Technical field
This utility model relates to a kind of nut structure, particularly relates to a kind of embedded hexagon nut with flange, is specifically suitable for
In improving nut pretightning force and connection reliability.
Background technology
Hexagon nut with flange generally uses with bolt matching, is mainly used in being fastenedly connected two and two or more with leading to
The mechanical component in hole.Screw bolt and nut uses in commercial car in a large number, a lot of adnexaes such as fuel tank, urea tank and the rigidity of battery frame
Support all needs to be fixed on longitudinal beam by screw bolt and nut.Except the connection between stiffener, also part plastic is also
Can be connected with stiffener, such as mouldings such as the plastic mud fender of commercial car and plastics bumper bars.The part of injection mo(u)lding is for protecting
Demonstrate,prove enough intensity and need to increase at installing hole periphery the reinforcement of rule, cause part thickness larger at installing hole, separately
The outer Performance Characteristics of moulding material own determine it cannot machining internal thread, so needing to select the longer bolt of specification to come
Join nut fastening connection piece.Bolt easily falls moment of torsion during life-time service, loosens, in the case of connector is working of plastics more
Very.In vehicle traveling process, owing to the shake of vehicle easily makes the screw bolt and nut of fastening mud guard loosen, cause abnormal sound, very
Fall to the mud guard that gets loose due to bolt in the long-distance transport of vehicle, cause serious vehicle accident.
In sum, securing member tighten the most important with locking.It is initial that the effectiveness of threaded fastener generally depends on it
The degree being tightened, in the case of securing member and structure allow, pretightning force is the biggest, connects the most reliable, and structure fatigue life is more
High.During assembling, pretightning force is controlled by screw-down torque.Screw-down torque is equal to frictional resistance moment and the nut end of screw thread pair
Frictional resistance moment sum between face and connected piece supporting surface.Increase the length of action of screw thread pair and add between big nut and connector
Supporting surface all can increase screw-down torque, thus strengthen pretightning force, reach locking effect.
Chinese patent Authorization Notice No. is CN204553501U, and authorized announcement date is the utility model on August 12nd, 2015
Patent discloses a kind of retaining flange nut.It is characterized in including that hex nut, hex nut lower end are provided with ring flange, flange
It is provided with on dish and prevents the unidirectional inclined-plane ratchet of own rotation and securing member is executed stressed boss.Although this utility model energy
Increase pretightning force to a certain extent, but it still suffer from following defect:
The female thread length of action of this utility model is shorter, and pretightning force is less, easily falls moment of torsion during life-time service.
Summary of the invention
The purpose of this utility model is to overcome the engagement problem that reach is short, pretightning force is little present in prior art,
Provide and a kind of engage reach length, embedded hexagon nut with flange that pretightning force is big.
For realizing object above, technical solution of the present utility model is:
A kind of embedded hexagon nut with flange, including hex nut and flange, the bottom surface of described hex nut and flange
End face fixing connect；
Described hexagon nut with flange also includes embedded swivel nut, and the end face of described embedded swivel nut is solid with the bottom surface of flange
Determining to connect, described hex nut, flange and embedded swivel nut are coaxially disposed, described hex nut, flange and embedded swivel nut
Middle part is through offers same internal thread hole.
Length L of described embedded swivel nut is more than or equal to 20 millimeters, and the thickness d of described embedded swivel nut is more than or equal to 4 millis
Rice.
Described internal thread hole is connected with bolt thread, and described bolt includes screw head and screw rod, one end of described screw rod and spiral shell
Head is fixing to be connected, and the other end of described screw rod is threadeded with internal thread hole after passing thin plate, slab successively, described embedded spiral shell
Overlap the insertion of the installing hole with slab to coordinate.
Described thin plate is metal material manufacture, and described slab is nonmetallic materials manufacture.
The thickness of described slab is more than or equal to 20 millimeters.
The end face of described flange is globoidal structure.
Compared with prior art, the beneficial effects of the utility model are:
1, the embedded swivel nut in a kind of embedded hexagon nut with flange of this utility model can increase the screw thread of nut
Length of action, is effectively improved pretightning force.Therefore, the design pretightning force is big, and connection reliability is high.
2, the nut structure of a kind of embedded hexagon nut with flange of this utility model is applicable to connect two kinds of unlike materials
Structure, owing to slab its intrinsic frequency of vibration different from thin plate material is different, if slab directly contacts with bolt, hold
Easily cause bolt and fall moment of torsion, be that the connection between bolts and nuts loosens, and the embedded swivel nut of the design embeds in slab, excellent
Change the force environment of bolt, simultaneously on the premise of not increasing spiro rod length, increased engagement reach, saved cloth and be empty
Between.Therefore, the design the most effectively prevents nut loosening, and it is little to engage reach length, arrangement space.
