Fig. 4 is the nut top view of the utility model.
In figure:
Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is a kind of Novel bolt nut mechanism.
Embodiment:
A kind of Novel bolt nut mechanism, including screw bolt and nut 3, the bolt include bolt head 1, are molded over bolt Bolt neck 6 on first 1 and the shank of bolt 2 being molded on bolt neck 6, the bolt head 1 is in polygon, the bolt head Nuts 5 is provided on 1, the 1 upper surface center of bolt head is provided with polygonal grooves 11, the bolt head 1 Lower surface is provided with gasket 4, and 4 through-hole diameter of gasket matches with 2 diameter of shank of bolt, and 6 diameter of bolt neck is small In being provided on 2 diameter of shank of bolt, the shank of bolt 2 side is connect with bolt neck 6 from shank of bolt 2 extend to 2 bottom of shank of bolt The external screw thread 21 at end, the 2 lower surface center of shank of bolt are provided with the first internal screw thread 22, and the nut 3 includes the Two internal screw threads 31 and gasket 32, the spiral shell 3 are in polygon prism shape, and the second internal screw thread 31 perforation is set to nut 3 Inner hub location, the gasket 32 are glued to the upper and lower surfaces of nut.
Wherein, the nuts 5 uses rubber material, and the nuts 5 is internally provided with and 1 same shape of bolt head Inner cavity.Nuts 5 agrees with completely with bolt head 1, keeps nuts 5 not easily to fall off, and adequately protect bolt head 1, due to bolt head 1 Shape easily causes abrasion, needs safeguard measure.
Wherein, 11 depth of groove is less than 1 length of bolt head, and groove 11 is " ten " font, line-styled, quadrangle With one of hexagon flute profile.The depth of groove 11 can make if more than 1 length of bolt head under the intensity and toughness of bolt head 1 Drop, is easy to cause the fracture of bolt head 1.
Wherein, 4 lower surface of gasket is provided with circular wave of the multi-turn along 4 center of gasket to external diffusion.Protect bolt With bolt head 1, increase the pressure of bolt, the fastening force of strengthening stud.
Wherein, the drilling depth of first internal screw thread 22 is less than 2 length of shank of bolt.In order to guarantee the strong of shank of bolt 2 Degree and rigidity, the drilling depth of the first internal screw thread 22 are easy to cause the fracture of shank of bolt 2 if more than the length of shank of bolt 2.
Wherein, the external screw thread 21, the first internal screw thread 22 and 31 forming direction of the second internal screw thread are dextrorotation forward screw thread. First internal screw thread 22 is viewed as forward direction by 2 lower surface of shank of bolt, and positive first internal screw thread 22 of observation bolt is reverse thread, is Another means of demounting bolt.
Wherein, the upper and lower surfaces of the nut 3 are polygon, and polygon number of edges is odd number, polygon number of edges More than or equal to three.Number of edges is designed as odd number, is that must use to special tool in installation and removal nut 3, general tool can not Installing and dismounting nut 3.
Wherein, the gasket 32 uses rubber material, gasket 32 upper surface of fitting nut 3 and following table completely Face.Gasket 32 primarily serves waterproof action, and fitting completely can also adequately protect nut 3 and the second internal screw thread 31.
The application method of this example:
Check that bolt reeve fastening article with the presence or absence of damage, is accomplished fluently hole by the surface of screw bolt and nut 3 in advance, bolt with Installation and gasket 4 between fastening article, in stud base's precession nut 3, external screw thread 21 and the second internal screw thread 31 match, can be with It is smoothly threadedly coupled, due to the polygonal post design of bolt head 1, fastening work previous work personnel can be with hand first by bolt Precession nut 3, saves time and physical strength, using the one side of the closely fastening article of particular tool fixture nut 3, is rotated using spanner Bolt carries out fastening more further.Nuts 5 is installed after being installed on bolt head 1.In disassembly process, we Specific tool ejector nut 3 can only be used, since nut 3 is special nut, the tool of installation and removal is also special tool. Special nut can play good confidentiality.
If bolt is broken, bolt internal structure is leaked out, it is only necessary to some anti-using reversed bolt or reversed screw etc. To fastener, the inside of precession shank of bolt 3 is threadedly coupled with the first internal screw thread 22, precession can not be further when revolve again Turn, that is, can be taken off another part of the bolt of fracture.
One embodiment of the utility model is described in detail above, but the content is only the utility model Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
