Abstract
The utility model discloses an anti-rotation quick-release self-locking nut. The anti-rotation quick-release self-locking nut comprises a 'Tu' (Tu is a chinese character, meaning convex)-shaped nut body composed of a rectangular solid (1) and a boss (2), wherein the center of the boss (2) is provided with an inner thread (3) running through the boss (2) and the rectangular solid (1); and the boss (2) is provided with two arc surfaces (4), two positive rotation limiting surfaces (5) and two negative rotation limiting surfaces (6). According to the anti-rotation quick-release self-locking nut disclosed by the utility model, quick connection and disconnection are realized under the matching effect of the rectangular solid on the quick-release nut and a T-shaped groove or a long hole; and the nut can be prevented from rotating with a bolt, the mounting and dismounting efficiency is improved, the production cost is reduced, and the working intensity is reduced. The quick mounting or dismounting requirements of the long hole or the T-shaped groove can be satisfied, and the application of the quick-release fastener in branch fields of cable clamps and the like can be met. Moreover, the anti-rotation quick-release self-locking nut is fast and simple to produce, has high safety and reliability and is convenient to maintain.
Description
Technical field
the utility model relates to a kind of anti-rotation quick-release self-locking nut, belongs to the link technical field.
Background technique
are in machining or machinery, or in some cables or pipeline fixing, the linkage structure that often can use bolts and nuts is in order to steady job or clip.Some occasion is awkward by space boundary, and also some has requirement to handling speed, so regular meeting adopts the quick-release mode.Common quick-release mode is high to the performance requirement of sheet material, and quick-release moment is unstable, poor reliability, and difficulty of processing is big, and cost of production is high; Often dismounting is used the most outstanding in this branch field of cable clip; Some oil pipe, tracheae etc. are stressed bigger; And need often dismounting; The fastening piece of common fast discharging method does not reach requirement, and the fatigue resistance aspect can not meet the demands, because of its fatigue resistance difference and poor reliability often cause the flight safety coefficient of aerospace vehicle low high with maintenance cost.
Summary of the invention
The purpose of
the utility model is, a kind of anti-rotation quick-release self-locking nut is provided.Can satisfy the quick mounting or the dismounting requirement of slotted hole or T-slot, satisfy the fastener application that cable clip five equilibrium props up the quick-release in field.And produce quick and easyly, safety reliability is high, and is easy to maintenance.
The technological scheme of the utility model
a kind of anti-rotation quick-release self-locking nut comprises " protruding " font nut body that is made up of cuboid and boss, and the boss center is provided with the internal thread that runs through boss and cuboid; Boss is provided with two arc surfaces, two dextrorotation confined planes and two derotation confined planes.
In
aforementioned anti-rotation quick-release self-locking nut, the radius R of said arc surface equals the width W of dextrorotation confined planes or derotation confined planes.
In
aforementioned anti-rotation quick-release self-locking nut, the end face of said cuboid is provided with restraining groove; Restraining groove is parallel with the length direction of cuboid, the both sides that are located at boss of symmetry.
In
aforementioned anti-rotation quick-release self-locking nut, said internal thread is provided with closing in, closes up to be positioned at the screw mouth place of cuboid bottom.
compared with prior art, the utility model cooperates through the cuboid on the fast removing nut and T-slot or slotted hole to be realized being connected fast and separating; And can prevent that nut from along with bolt rotates together, having improved installation and removal efficient, and reduced cost of production, alleviated working strength.Can satisfy the quick mounting or the dismounting requirement of slotted hole or T-slot, satisfy the fastener application that cable clip five equilibrium props up the quick-release in field.And produce quick and easyly, safety reliability is high, and is easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The spacing view of nut when Fig. 2 is dextrorotation;
spacing view of nut when Fig. 3 is derotation.
Being labeled as in
accompanying drawing: 1-cuboid, 2-boss, 3-internal thread, 4-arc surface, 5-dextrorotation confined planes, 6-derotation confined planes, 7-restraining groove, 8-slotted hole.
Embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.
a kind of anti-rotation quick-release self-locking nut, as shown in Figure 1.Comprise " protruding " font nut body that is made up of cuboid 1 and boss 2, boss 2 centers are provided with the internal thread 3 that runs through boss 2 and cuboid 1; Boss 2 is provided with two arc surfaces 4, two dextrorotation confined planes 5 and two derotation confined planes 6.The radius R of said arc surface 4 equals the width W of dextrorotation confined planes 5 or derotation confined planes 6.The end face of said cuboid 1 is provided with restraining groove 7; Restraining groove 7 is parallel with the length direction of cuboid 1, the both sides that are located at boss 2 of symmetry.Said internal thread 3 is provided with closing in, closes up to be positioned at the screw mouth place of cuboid 1 bottom.
The working principle of the utility model
the utility model is mainly used the quick connection of T-slot or slotted hole, below is the application example of anti-rotation quick-release self-locking nut when being connected fast with slotted hole.As shown in Figure 2 during quick mounting, the cuboid on the nut 1 is passed along slotted hole 8; As shown in Figure 3 then, cuboid 1 is rotated in the forward 90 degree, at this moment the dextrorotation confined planes on the boss 25 touches with the long edge joint of slotted hole 8, makes nut can not continue rotation, has played the anti-rotation effect.During fast quick-detach, under state as shown in Figure 2, the 1 counterclockwise counterrotating 90 of the cuboid on the nut is spent; Make cuboid 1 as as shown in Figure 3, go to, then cuboid 1 is taken out from slotted hole 8, realized quick disassembling function along the slotted hole direction.
Some explanation of the utility model:
the utility model most critical be the shape of protection nut, the one, " protruding " glyph shape that combines formation of protection cuboid 1 and boss 2; The 2nd, the shape of protection boss 2.The horizontal section of boss 2 is actually a square, and foursquare two diagonal angles are fallen into the shape that fillet forms.The radius of fillet should equal the half the of the square length of side.The foursquare length of side should equal the bond length of slotted hole.Through chamfering, on boss 2, form two arc surfaces 4, two dextrorotation confined planes 5 and two derotation confined planes 6.When dextrorotation confined planes 5 is bolt screw-in nut, the face that the long edge joint of boss side surfaces and slotted hole touched when boss 2 can not rotate.When derotation confined planes 6 is bolt back-out nut, the face that the long edge joint of boss side surfaces and slotted hole touched when boss 2 can not rotate.Be provided with restraining groove 7 on the cuboid 1, restraining groove 7 can cooperate by the positive stop lug boss of both sides below being located at slotted hole, prevents that cuboid 1 from freely rotating.The utility model can adopt disposable thermal rammer moulding, again fraising and attack internal thread.The oral area of internal thread is provided with at least one point and closes up (not drawing among the figure), plays self-locking action.
