Abstract
The invention relates to a double-end locking nut which comprises two nuts, a connecting pipe and a plurality of steel balls, wherein the two nuts are arranged on the two ends of the connecting pipe, one side wall of the two nuts is provided with a thread through hole, and the nuts are provided with a plurality of grooves on the inner wall of the thread through hole; the steel balls are arranged in the grooves, the bottom surfaces of the grooves are arc faces circumferentially extending along the inner wall of the thread through hole, one circumferential end of the bottom surface of each of the grooves is directly connected with the interior of the thread through hole of each nut body, and the other circumferential end of the bottom surface of each of the grooves is a step plane which is vertical to a shaft line of the thread through hole; and the radial depth is gradually reduced along the thread rotation direction of the nuts, and the diameter of each steel ball is slightly greater than the size of the radial maximum depth. The double-end locking nut provided by the invention has the advantages of strong anti-theft performance, good security, strong fastening ability, low possibility of looseness, and long service life.
Description
Technical field
The present invention relates to a kind of nut, especially a kind of double-head lock jack panel.
Background technique
Existing plain nut is very extensive for the fastening applications of general stationary thing, uses also very convenient.But its existence adjusting polarization is poor and the shortcoming of less stable, and nut tends to produce loosening, brings very big insecurity for operation or machine.Particularly on some large-scale Work machines or machine, because the high speed of the roll shaft in machinery choosing dress and inside and outside vibrations, it is loosening to tend to make the built-in nut that is fixed on the roll shaft to produce; And machinery can not be run well and proper functioning; And existing nut theftproof performance is relatively poor, at some special occasions, and the phenomenon of again can the lawless person stealing and destroying; The lock ability that present locking nut has is not strong, the shortage theftproof performance that has.
Summary of the invention
In order to overcome above defective, the technical problem that the present invention will solve is: it is strong to propose a kind of theftproof performance, safe, the double-head lock jack panel that fastening ability is strong.
The technological scheme that the present invention adopted is: a kind of double-head lock jack panel; Comprise two nuts, connecting tube and some steel balls; Said two nuts are arranged on the two ends of connecting tube, in the sidewall of said two nuts a tapped through hole are set, and said nut has several trough on the screw inwall; Said steel ball is arranged in the groove; The bottom surface of said groove is the arc shaped surface along screw inwall extending circumferentially, and the screw of the circumferential end in the bottom surface of said groove and nut body is inner directly to be connected, and the circumferential the other end is one and the step surface of screw axis normal; Its radial depth reduces with the screw thread rotation direction of nut gradually, and the somewhat larger in diameter of said steel ball is in the size of maximum depth radially.
According to another preferred embodiment, comprise that further said groove is two, said groove circumferentially is symmetrically distributed along the screw inwall of nut body, and two step surfaces are on same center line of nut body.
According to another preferred embodiment, comprise that further said groove is arranged on apart from nut body upper-end surface 3-5 circle screw thread place.
According to another preferred embodiment, comprise that further said tapped through hole is the screw thread step through-hole.
According to another preferred embodiment, the vestibule that further comprises said connecting tube is a screw, and the screw aperture of said connecting tube equals the screw aperture of nut.
According to another preferred embodiment, comprise that further said connecting tube and nut are integrally formed.
The invention has the beneficial effects as follows: pass the tapped through hole on the nut through using screw, the mode that this superposition is fixing has ensured that nut can not become flexible, and safety coefficient is high, is arranged on groove and steel ball in the nut, has reached the purpose of antitheft.
Description of drawings
Fig. 1 is the plan view of the preferred embodiments of the present invention;
Fig. 2 is the plan view of the preferred embodiments of the present invention;
Among the figure: 1, nut, 2, connecting tube, 3, groove, 4, steel ball, 5, tapped through hole.
Embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1; A kind of double-head lock jack panel comprises two nuts 1, connecting tube 2 and some steel balls 4, and said two nuts 1 are arranged on the two ends of connecting tube 2; One tapped through hole 5 is set in one sidewall of said two nuts 1; Said nut 1 has several trough 3 on the screw inwall, said steel ball 4 is arranged in the groove 3, and the bottom surface of said groove 3 is the arc shaped surface along screw inwall extending circumferentially; The circumferential end in the bottom surface of said groove 3 directly is connected with the screw of nut 1 body is inner; Circumferentially the other end be one with the step surface of screw axis normal, its radial depth reduces with the screw thread rotation direction of nut 1 gradually, the somewhat larger in diameter of said steel ball 4 is in the size of maximum depth radially.
In addition, said groove 3 is two, and said groove 3 circumferentially is symmetrically distributed along the screw inwall of nut 1 body, and two step surfaces are on same center line of nut 1 body.
In addition, said groove 3 is arranged on apart from nut 1 body upper-end surface 3-5 circle screw thread place.
In addition, said tapped through hole 5 is the screw thread step through-hole.
In addition, the vestibule of said connecting tube 2 is screws, and the screw aperture of said connecting tube 2 equals the screw aperture of nut 1.
In addition, said connecting tube 2 is integrally formed with nut 1.
When installing and using, when the nut shin bone after on some mechanical parts, pass the screw through-hole on the nut with screw; And with screw be provided with in advance with nut on the corresponding tapped blind hole of screw through-hole in, the fixing mode of this superposition has guaranteed that nut can not become flexible, safety coefficient is high; At the dismounting nut be, repercussion screws out nut, and bolt thread applies the circumferential active force of repercussion to steel ball; Knowledge figure releases groove with steel ball and since the radial depth of groove year nut body screw thread choosing dress direction reduce gradually, steel ball is stuck in the groove; Thereby can't screw out nut, realize anti-theft feature.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
