Abstract
The invention discloses an anti-loosing steel wire thread sleeve, comprising a spring-shaped concentric body of inside thread and outside thread; the cross section of the outside thread in the concentric body of inside thread and outside thread is in the shape of triangle, and the outer angle is 60 degrees; the cross section of the inside thread in the concentric body of inside thread and outside thread is symmetrical to the cross section of the outside thread, the inside angle is 60 degrees, and one diagonal side closing to the tooth bottom is in the shape of wedge, and the wedge angle is beta. According to the anti-loosing steel wire thread sleeve, the self-locking between the inside thread of the thread sleeve and the thread of the connecting bolt can be realized by changing the sectional shape of the steel wire thread sleeve material; therefore, the anti-loosing steel wire thread sleeve has the performances of reliable shockproof and anti-loosening.
Description
Technical field
The present invention relates to a kind of threaded connector, particularly relate to a kind of locking shaped steel silk swivel nut.
Background technique
Steel-wire screw-socket is a kind of novel threaded fastener, and it is a kind of concentric body of a kind of spring-like internal and external threads that is accurately processed by the Stainless Steel Wire of highi degree of accuracy diamond-shaped cross-section.During use, on matrix, process thread Pilot hole, be installed in steel-wire screw-socket in the bottom outlet again, form and the identical standard female of regular screw threads size, can screw with the outside thread product of standard with special-purpose bottom outlet screw tap.It is embedded in the screw thread of low intensive engineering materials such as cast iron, glass fibre reinforced plastics, plastics, aluminium or magnesium alloy, have join strength, shock resistance and the anti abrasive function of increasing, and can protect the matrix screw thread by dispersive stress, prolong the working life of matrix greatly.In addition, the screw thread that steel-wire screw-socket can also be on protocorm is threaded off or during random tooth, as the reparation means, and the unlikely integral body that causes is scrapped, and easy to maintenance, fast, economical.At present, the steel-wire screw-socket technology has been widely used in industries such as Aeronautics and Astronautics, weapons, electrical equipment, instrument, automobile transportation, mine metallurgy, building, water pump, chemical fibre, chemical industry.
The ordinary steel wire swivel nut divides from its mounting type, and can be divided into two kinds: (1) has the mounting handle steel-wire screw-socket, also has been referred to as the handle swivel nut or the tail swivel nut is arranged; (2) no mounting handle steel-wire screw-socket is also referred to as stockless swivel nut or anury swivel nut.Having the tail steel-wire screw-socket can be divided into again has snap slot and does not have two kinds of snap slots, has the swivel nut of snap slot to be used for through hole, and the swivel nut of no snap slot is used for blind hole.The anury steel-wire screw-socket all has a similar ancistroid,ancistrous draw-in groove at two ends, when the anury swivel nut is installed, uses special-purpose setting tool, need not to distinguish the direction of swivel nut, directly installs to get final product.But the plain edition steel-wire screw-socket does not possess anti-loosening property, for this reason, on plain edition steel-wire screw-socket basis, develops a kind of lock type steel-wire screw-socket; There is the above polygonal clamp ring of a circle lock type steel-wire screw-socket intermediate portion, and when bolt is screwed into screw one half, bolt head is run into clamp ring; At this moment need to be screwed into the instrument reinforcing, the bolt spreading polygonal clamp ring of steel-wire screw-socket, conversely; The position, middle footpath of bolt has been blocked in the polygonal clamp ring, has played the locking effect.When being shaken and impact, screw can not become flexible, still; This lock type steel-wire screw-socket processing technology is complicated; Cost is high, also following problem can occur in the use: when (1) bolt screws in the polygonal clamp ring, receive the radially effect of chucking power; Improper like Deformation control, swivel nut can rotate with bolt; When (2) bolt screws out, receive the radially effect of chucking power equally, also can cause swivel nut to draw off with the bolt one.
Summary of the invention
The present invention seeks to provides a kind of locking shaped steel silk swivel nut to the defective that existing technology exists, and can realize effectively locking purpose.
The present invention adopts following technological scheme for realizing above-mentioned purpose: locking shaped steel silk swivel nut, comprise the concentric body of the internal and external threads that is spring-like, and the outside thread cross section shape triangular in shape of the concentric body of said internal and external threads, its exterior angle is 60 °; The internal thread cross section and the outside thread cross section of the concentric body of said internal and external threads are symmetrical set, and its interior angle is 60 °, and wherein a hypotenuse is being wedge shape near the tooth bottom, and its key groove is β.
As preferably, said β angle is between 25 °-35 °.
As preferably, said β angle is 30 °.
Beneficial effect of the present invention really is: through changing the sectional shape of steel-wire screw-socket silk material, just can realize the self-locking between swivel nut internal thread and the connecting bolt screw thread, have reliable antidetonation, anti-loosening property; Load evenly distributes, and improves fatigue strength; Do not receive the influence of temperature acute variation and environment; Need not any auxiliary locking original paper,, reduce overall cost like spring washer, lock washer etc.
Description of drawings
Fig. 1 is the plan view of the locking shaped steel silk of the present invention swivel nut;
Fig. 2 is an existing technology steel-wire screw-socket silk material sectional view;
Fig. 3 is the locking shaped steel silk of a present invention swivel nut silk material sectional view;
Fig. 4 is the locking shaped steel silk of a present invention swivel nut scheme of installation.
Among the figure, the locking shaped steel silk of 1-swivel nut, 2-matrix, 3-bolt, the concentric body of 12-internal and external threads.
Embodiment
Below in conjunction with accompanying drawing and embodiment, technological scheme of the present invention is done further to set forth.
Shown in Figure 2 is existing technology ordinary steel wire swivel nut silk material sectional view.As shown in figures 1 and 3, locking shaped steel silk swivel nut 1 comprises the concentric body 12 of the internal and external threads that is spring-like; The outside thread cross section shape triangular in shape of the concentric body 12 of said internal and external threads; Its exterior angle is 60 °, and internal thread cross section and outside thread cross section are symmetrical set, and its interior angle is 60 °; And wherein a hypotenuse is being wedge shape near the tooth bottom, and its key groove is β.Change between 25 °-35 ° at said β angle.Its optimal value β=30 °.Silk material cross section shown in Figure 3 has been applicable to tail locking shaped steel silk swivel nut and the locking shaped steel silk of anury swivel nut.
As shown in Figure 4; Locking shaped steel silk swivel nut 1 is screwed in the matrix 2; When bolt 3 and locking shaped steel silk swivel nut 1 are tightened; 30 ° of wedge shape inclined-planes that the crest threaded line total length of bolt 3 gets into the swivel nut internal thread are tightened, and put on the normal force that is produced on the wedge shape inclined-plane and become 60 ° of angles with the axis of bolt 3, rather than 30 ° of angles of common standard screw thread.The normal force that produces when therefore fastening has greatly anti-loose ability much larger than the common standard screw thread.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
