Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of hold down gag of lock nut.
Background technique
Nut is one of fastening piece conventional in mechanical field, it usually and bolt or screw rod with the use of, for being fastenedly connected two parts with through hole.End face due to plain nut mostly is smooth plane, therefore, two are fastened on after on the part of through hole when this nut coordinates with bolt or screw rod, it and the frictional force be connected between part can be very little, especially when being subject to vibrating, this nut be easy to along the screw thread on bolt or screw rod voluntarily pine move back.Therefore, people improve nut, as on July 24th, 2012, " lock nut " of Ningbo Correspondent mechanical links Co., Ltd invention, its Chinese license notification number CN202732619 U, technological scheme disclosed in this patent: " sidewall of described nut body has two radial tapped through holes be screwed into for housing screws, the symmetrical and coaxial line of the radial tapped through hole described in two." this technological scheme also Shortcomings: at nut body, radial tapped through hole is set; and wear housing screw locking can only postpone lock nut voluntarily pine move back the time; Long-Time Service; housing screw can first voluntarily pine move back; then cause lock nut voluntarily pine move back, therefore can not prevent for a long time nut along the screw thread on bolt or screw rod voluntarily pine move back.
Summary of the invention
For the deficiency that prior art exists, it is good that the purpose of this utility model is to provide a kind of reasonable in design, anti-loosening property, and nut can be prevented for a long time along the hold down gag of lock nut that moves back of pine voluntarily of the screw thread on bolt or screw rod.
For achieving the above object, the utility model provides following technological scheme: a kind of hold down gag of lock nut, comprise housing screw, Returnning spring, contiguous block and rubber pad, described housing screw afterbody is provided with threading hole, anti-slack rope is equipped with in described threading hole, and anti-slack rope two ends are to threading hole extension, described Returnning spring one end is welded on housing screw head, the Returnning spring the other end is welded to connect block, described contiguous block deviates from Returnning spring end and is fixedly connected with rubber pad, described rubber pad deviates from the positioning part that contiguous block end is provided with arc, described positioning part is provided with several positioning convex.
By adopting technique scheme, when screwing housing screw, the positioning part of rubber pad compresses on existing bolt or screw rod, and under the effect of Returnning spring, the positioning convex of rubber pad can increasing friction force, the anti-slack rope of housing screw afterbody can be connected and fixed with existing lock nut and be integrally formed, when being subject to vibrating, housing screw can not move back by pine voluntarily, thus makes when being subject to vibrating, lock nut can not along the screw thread on existing bolt or screw rod voluntarily pine move back, anti-loosening property is good; Reasonable in design, can prevent for a long time nut along the screw thread on bolt or screw rod voluntarily pine move back.
The utility model is set to further: described housing screw is provided with glove groove near head position, and this glove groove built-in type is installed with magnet.By this setting, housing screw can be adsorbed on the hole wall of existing lock nut, connects more reliable, not easily loosens.
The utility model is also set to further: described housing screw arranges annular groove near tail position, is socketed with rubber buffer ring in described annular groove.By this setting, rubber buffer ring is arranged rationally, housing screw is connected more reliable.
The utility model is also set to further: be provided with two Returnning springs between described housing screw head and contiguous block, and two Returnning springs are separately positioned on two ends, contiguous block left and right.By this setting, Returnning spring quantity arranges rationally, and contiguous block locating effect is better.
The utility model is also set to further: described rubber pad and contiguous block are adhesively fixed.By this setting, rubber pad and contiguous block easy to connect, fixing reliable.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is reasonable, when screwing housing screw, the positioning part of rubber pad compresses on existing bolt or screw rod, under the effect of Returnning spring, the positioning convex of rubber pad can increasing friction force, the anti-slack rope of housing screw afterbody can be connected and fixed with existing lock nut and be integrally formed, when being subject to vibrating, housing screw can not move back by pine voluntarily, thus make when being subject to vibrating, lock nut can not along the screw thread on existing bolt or screw rod voluntarily pine move back, anti-loosening property is good; Reasonable in design, can prevent for a long time nut along the screw thread on bolt or screw rod voluntarily pine move back.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the enlarged diagram in I portion in Fig. 1.
Embodiment
See Fig. 1 and Fig. 2, the utility model discloses a kind of hold down gag of lock nut, comprise housing screw 1, Returnning spring 2, contiguous block 3 and rubber pad 4, described housing screw 1 afterbody is provided with threading hole 11, anti-slack rope 5 is equipped with in described threading hole 11, and anti-slack rope 5 two ends are to threading hole 11 extension, described Returnning spring 2 one end is welded on housing screw 1 head, Returnning spring 2 the other end is welded to connect block 3, described contiguous block 3 deviates from Returnning spring 2 end and is fixedly connected with rubber pad 4, described rubber pad 4 deviates from the positioning part 41 that contiguous block 3 end is provided with arc, described positioning part 41 is provided with several positioning convex 411.
As preferably, the length that threading hole 11 is stretched out at the present embodiment anti-slack rope 5 two ends is arranged arbitrarily according to actual needs, housing screw 1 is connected and fixed with existing lock nut by anti-slack rope 5 be integrally formed, this technological scheme, when being subject to vibrating, housing screw can not move back by pine voluntarily, thus makes when being subject to vibrating, lock nut can not along the screw thread on existing bolt or screw rod voluntarily pine move back.
For making the utility model structure more reasonable, as preferably, described in the present embodiment, housing screw 1 is provided with glove groove 12 near head position, and this glove groove 12 built-in type is installed with magnet 6.
