Abstract
The invention provides an octagonal nut. The octagonal nut comprises an octagonal nut body, wherein the octagonal nut body is a regular eight-angular prism body and is provided with eight side arrises and eight side walls; the eight side arrises are vertical to the bottom surface; a central through hole is formed in the center of the octagonal nut body; round through holes are formed in the side walls; screw threads are formed on the inner surfaces of the round through holes; each round through hole is correspondingly provided with a bolt; identical bosses are arranged at every side arris of the octagonal nut body; the height of the bosses is equal to that of the side arrises; included angles between the outer surfaces of the bosses and the side walls are the same. The octagonal nut has the beneficial effects that the problem that the octagonal nut is not easy to reinforce is solved in the way of forming bolt holes in the side walls of the octagonal nut, and the nut is more convenient to use and is not easy to damage due to the fact that the bosses are arranged at the side arrises of the octagonal nut. The octagonal nut has the advantages of simple structure, easiness in operation, flexibility in use, uniform stress and uneasiness in deformation. The octagonal nut can also be designed into different shapes according to the shape of a fastening workpiece, so that the octagonal nut has the characteristic of wide application range.
Description
Technical field
The invention belongs to the metal fastenings technical field, especially relate to a kind of all directions nut be widely used in the machinery such as automobile, boats and ships.
Background technique
In nearly all machinery, all need various component are carried out to consolidation process, particularly more severe at the residing environment of component, during often in the face of mechanical shocks such as vibrations, consolidation process is more essential, in general, by nut and the direct frictional force of bolt, carries out the fastening effect that just can reach against shock, protecting against shock, even if need high-grade against shock effect, also can achieve the goal by many increases nut.
But in some particular component, existing nut can't play the effect of against shock, Drop-proof, when at needs, fastening parts are cylinder, need to carry out fastening to the concussion up and down of cylinder, also to the swing of cylinder be limited, when at needs, fastening cylinder body shape is non-common polygonal, most bolts can't be used more.
In addition, nut itself also has some shortcomings, as there is loosening risk etc. between nuts and bolt, the profile of nut mostly is Hexagon or Octagon, narrow at the residing environment of nut, and, during fastening nuts very tight, fastening nuts or the situation of slide fastener easily occurs while unclamping, cause component normally to use.
Therefore existing nuts and bolt structure exists inapplicable or is using difficulty, the poor shortcoming of using effect in specific environment, requires further improvement and perfect.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of all directions nut, especially is suitable for the special workpieces such as cylinder in fastening machines equipment.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of all directions nut, comprise nut body from all directions, and wherein, described all directions nut body is equilateral eight prisms, has eight inclines perpendicular to bottom surface and eight sidewalls; The center of described all directions nut body is provided with central through bore, and sidewall is provided with manhole, and described manhole internal surface is provided with screw thread, and each manhole correspondence is provided with a bolt.
Further, every incline place of described all directions nut body is provided with identical boss, and the height of described boss is identical with the incline height, and the outer surface of described boss is identical with the sidewall angle of all directions nut body.
Further, the internal surface of described central through bore is provided with screw thread.
Further, the shape of described central through bore is identical with the profile of required fixing workpiece.
Further, described eight sidewall Center Gap are provided with manhole.
Further, described all directions nut body and bolt have identical hardness.
Advantage and good effect that the present invention has are: the mode that the technical program is opened bolt hole by all directions nut sidewall has solved the difficult problem of reinforcing of cylinder, the boss that nut incline place arranges from all directions is convenient in the nut using process, not fragile, have simple in structure, easy operating, used flexibly stressed even on-deformable advantage, can also be designed to difformity according to the shape of the fastening workpiece of need, there are characteristics applied widely.

Embodiment
The present invention is a kind of all directions nut, as shown in Figure 1, comprises nut body 1 from all directions, and wherein, described all directions nut body 1 is equilateral eight prisms, has eight inclines perpendicular to bottom surface 8 and eight sidewalls 3;
The center of described all directions nut body 1 is provided with central through bore 2, and sidewall 3 is provided with manhole 4, and described manhole 4 internal surfaces are provided with screw thread, and each manhole 4 correspondence is provided with a bolt 5.Every incline 8 places of described all directions nut body 1 are provided with identical boss 6, and the height of described boss 6 is highly identical with incline 8, and the outer surface of described boss 6 is identical with sidewall 3 angles of all directions nut body 1.
In the technical program, incline 8 optimizations of nut body 1 from all directions are provided with the boss shape, this distinctive appearance can alleviate instrument in situation fastening or slide fastener while unclamping nut, and particularly in the situation that narrow space or nut are very tight, this design is more convenient, practical.
The internal surface of described central through bore 2 is provided with screw thread.
Central through bore 2 is provided with screw thread can further increase the frictional force between cylinder 7 and all directions nut body 1, be conducive to increase the locking effect of workpiece, but, increase screw thread and also can increase the equipment difficulty, particularly in small space, can increase the difficulty of construction of maintenance, need to whether select the screw thread of practical central through bore 2 internal surfaces according to different situations.
The preferred cross section of described all directions nut body as shown in Figure 3.Eight sidewall Center Gap of described all directions nut body are provided with manhole.Fig. 4 has shown the Octagon foundry goods profile schematic diagram of nut from all directions.
Side-wall hole can increase bolt 5, by the fastening cylinder 7 of more bolt 5, better effects if; Not perforate can reduce the casting cost and lower the complexity of construction, maintenance, can adjust flexibly according to actual service condition.
The cross section of described cylinder 7 can be circle, rectangle or other polygonals, and central through bore 2 shapes of described all directions nut body 1 are always corresponding with the cross section of cylinder 7.
Described all directions nut body 1 and bolt 5 have identical hardness, and arranging of this set, particularly bolt 2 intensity can guarantee that nut in use keeps stable, a high-intensity fastening effect from all directions, are difficult for occurring accident loosening and that come off.
