Description
Technical Field
The utility model relates to a locking fastener technical field especially relates to a novel check bolt.
Background
It is known that, in the mechanical field, some mechanical equipment through bolted connection have not hard up possibility when equipment moves, and in order to prevent that equipment from producing the bolt pine in the operation process and taking off, can use locknut to lock the position of easily taking off under most circumstances, but present locknut structure is various, considers the cost, and the locking mode that uses double-deck nut at present is comparatively general, and this kind of locking mode can reduce the possibility that mechanical equipment pine takes off to a certain extent, but can't avoid completely.
To sum up, to the drawback in prior art, as this trade technical staff, how through technical improvement, design a novel check bolt, its accessible improves screw rod and nut, makes it have stable locking effect of taking off to this kind of check bolt must not have great increase in cost than current check bolt, and can make and use widely in batches.
Disclosure of Invention
In view of the above drawbacks of the prior art, the present invention provides a novel anti-loosening bolt, which includes a threaded rod, wherein the threaded rod is designed into an anti-loosening section and a locking section; the anti-loosening section is designed on the outer side, and the locking end is designed on the inner side; the anti-loosening section is provided with a thread with a reverse rotation direction to that of the locking section; the diameter of the external thread of the anti-loosening section is smaller than that of the external thread of the locking section;
the locking section is provided with a locking nut, and the surface where the locking nut and the locking nut are combined is respectively provided with a locking convex tooth and a locking convex tooth.
The outer diameter of the locknut is the same as that of the locknut.
The locking convex teeth and the anti-loosening convex teeth are designed in a radial mode.
The tooth height of the locking convex teeth and the anti-loosening convex teeth is 0.5-2 mm.
The locking nut is provided with a counter bore on one side facing the locking nut, and the outer diameter of the counter bore is based on the standard that the locking section can be smoothly inserted and does not shake.
The utility model discloses following beneficial effect has: through the above design, the utility model adopts two-section design, and the diameter of the anti-loose section arranged on the outer side is smaller than that of the locking section, and the two-section screwing direction design is reverse, through the design, the locking nut locks and fixes the equipment by the anti-loose nut for the second time, if the loosening phenomenon occurs, the locking nut screws out to the outer side, the screwing direction is reverse to the screwing direction of the locking section screw thread, the locking nut can extrude the anti-loose nut, because the screwing direction of the anti-loose nut is opposite to that of the locking section, when the locking nut withdraws reversely, the screwing direction of the reverse withdrawal is the same as the locking direction of the anti-loose nut, under the condition, the loosening of the locking nut can directly drive the anti-loose nut to lock and prevent the locking nut from withdrawing outwards, through the mode, the utility model can realize stable anti-loose, the utility model has novel and simple structure design, but the restriction cost rises, and the utility model discloses locking effect is obvious, stable, is fit for promoting in batches in machinery.

FIG. 3 is a schematic view of the structure of the present invention;
in the figure, 1, a screw rod, 2, a locking section, 3, a locking section, 4, a locknut, 5, a locknut, 6, a locking convex tooth, 7, a locking convex tooth, 8 and a counter bore.
Detailed Description
Other advantages and effects of the present invention will be apparent to those skilled in the art from the disclosure of the present invention.
According to the attached drawings: a novel anti-loose bolt comprises a screw rod 1, wherein the screw rod 1 is designed into an anti-loose section 3 and a locking section 2; the anti-loosening section 3 is designed on the outer side, and the locking end 2 is designed on the inner side; the anti-loosening section 3 is provided with a thread with a reverse rotation direction to that of the locking section 2; the diameter of the external thread of the anti-loosening section 3 is smaller than that of the external thread of the locking section 2, and the optimal diameter is 2/3 of the locking section 2 set by the anti-loosening section 3; the locking section 3 on be provided with locknut 4, be provided with lock nut 5 on the locking section 2, the face of locknut 4 and lock nut 5 combination on be provided with locking convex tooth 6 and locking convex tooth 7 respectively.
When the utility model is used, the locking nut 5 locks and fixes the equipment and then locks for the second time through the locknut 4, as shown in figure 1 and figure 3, if the loosening phenomenon occurs, the locknut 5 is screwed out to the outside, the screwing direction when screwing out is the reverse direction of the screw screwing direction of the locking section 2, the locknut 5 can extrude the locknut 4, because the screwing direction of the locknut 4 is opposite to that of the locking section 2, when the locknut 5 is withdrawn reversely, the screwing direction of the reverse withdrawal is the same with the locking direction of the locknut 4, under the condition, the loosening of the locknut 5 can directly drive the locknut 4 to lock, the locknut 5 is prevented from withdrawing outwards, in order to further increase the locking occlusion degree of the locknut 5 and the locknut 4, the utility model further improves the following on the basis of the above structure, the locking convex teeth 7 are designed to be radial, the locknut convex teeth 6 are also designed to be radial, through the design, when the locking nut 5 is withdrawn, the locking convex teeth 7 above the locking nut can drive the anti-loosening convex teeth 6 to rotate, and the biting force of the locking nut and the anti-loosening convex teeth is further improved; through multiple researches and practical verification, on the premise of not influencing the locking effect, the tooth heights of the locking convex teeth 7 and the anti-loosening convex teeth 6 are preferably designed within the range of 0.5-2 mm, and the height of 0.5 mm is optimal.
Furthermore, on the basis of the structure, for the use of convenience of personnel, the external diameter sizes of the locknut 4 and the locknut 5 are designed to be the same, and a user can realize locking and anti-loosening double actions by one wrench.
Still further, the utility model discloses when using, because of screw rod 1 divide into two sections different external diameter designs, locknut 4 and lock nut 5 are behind fixed object and locking application of force, have between the two and can't revolve the phenomenon of twisting the laminating soon, the utility model discloses especially be provided with a counter bore 8 on locknut 4 towards one side of lock nut 5, counter bore 8 external diameter use locking section 2 can smoothly insert and do not rock as the standard, through this kind of design, can make locknut 4 and lock nut 5 laminating locking.
To sum up, the utility model discloses structural design is novel, simple, under the unchangeable prerequisite of preparation raw and other materials, can restrict the cost and rise, and the utility model discloses locking effect is obvious, stable, is fit for promoting in the machinery field big batch.
