Abstract
The utility model relates to an anti-disengaging screw plug, which comprises a stud, and is characterized by further comprising a cylinder or a circular truncated cone-shaped elastic cushion, wherein the inner end of the stud is fixedly connected with the elastic cushion, and an inner hexagon hole is arranged on the outer end of the stud. The elastic cushion is made from rubber materials. The anti-disengaging screw plug has the beneficial effects that the anti-disengaging screw plug can effectively adsorb vibration of connected pieces, and prevents loosing.
Description
Technical field
The utility model relates to technical field of fastening, relates in particular to a kind of anti-loose plug screw.
Background technique
At industrial field, fastening piece is one of basic fittings, and the common effect of fastening piece is to connect or locking machine parts, but getting loose in use appears in fastening piece is inevitable, in order to prevent that fastening piece from getting loose, people have adopted various measures, and it is exactly wherein a kind of for example adding bullet pad to bolt.But in some occasion, such as holding out against screw, it does not have nut just can not adopt bullet pad yet; especially at the environment of some dithers; such as the straight pin plug screw on percussive hammer, due to the high frequency action of percussive hammer, make straight pin vibration violent; for often getting loose gradually until deviate to the spacing common plug screw of straight pin; and then cause straight pin to depart from body, and cause mechanical disorder, leave potential safety hazard; how to make plug screw not occur becoming flexible, become the problem that needs solve.
Model utility content
The utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and can effectively cushion machine vibration, prevented the anti-loose plug screw that becomes flexible.
The technological scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of anti-loose plug screw, comprises double-screw bolt, it is characterized in that, also comprise cylinder or conical cushion, the inner end of described double-screw bolt is fixedly connected with cushion, and the outer end of described double-screw bolt is provided with interior hexagonal hole.
The beneficial effects of the utility model are, have adopted cushion, can reduce the vibration of connected element, have prevented the loose or dislocation of plug screw.
On the basis of technique scheme, this model utility can also be done following improvement.
Further, described double-screw bolt and cushion are provided with the concaveconvex structure that structure matches on junction plane.
Adopt the beneficial effect of above-mentioned further scheme to be, can make both closely connect, can mutually not depart from; Easy accessibility can be changed at any time in the time that elastomer weares and teares simultaneously.
Further, described cushion is quality of rubber materials.
Adopt the beneficial effect of above-mentioned further scheme to be, rubber is drawn materials conveniently, and effective absorbing vibrational energy, prevents from becoming flexible, and can also reduce the rigidity friction that is attached thereto parts.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
In Fig. 1,1, double-screw bolt; 2, cushion; 3, concaveconvex structure; 4, interior hexagonal hole.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining this model utility, is not intended to limit the scope of this model utility.
As shown in Figure 1, a kind of anti-loose plug screw, comprises double-screw bolt 1, also comprises cylinder or conical cushion 2, and the inner end of described double-screw bolt 1 is fixedly connected with cushion 2, and the outer end of described double-screw bolt is provided with interior hexagonal hole 4.
Described double-screw bolt 1 and cushion 2 are provided with the concaveconvex structure 3 that structure matches on junction plane.
Described cushion 2 is quality of rubber materials.
Anti-loose plug screw of the present utility model has double locking effect after tightening, the one, after screwing up stud, push anterior rubber pad, the rubber pad compressive strain that is squeezed produces a reverse thrust, and this thrust has increased the frictional force between double-screw bolt and thread hole, thereby plays locking effect; The 2nd, rubber pad and locked workpiece push mutually as the straight pin in percussive hammer, have eliminated the movement clearance of straight pin under the situation of vibrations, alleviate or have offset the vibratory impulse power that should act on described double-screw bolt, have played anti-loose effect.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. an anti-loose plug screw, comprises double-screw bolt, it is characterized in that, also comprises cylinder or conical cushion, and the inner end of described double-screw bolt is fixedly connected with cushion, and the outer end of described double-screw bolt is provided with interior hexagonal hole.
2. anti-loose plug screw according to claim 1, is characterized in that, described double-screw bolt and cushion are provided with the concaveconvex structure that structure matches on junction plane.
3. anti-loose plug screw according to claim 1 and 2, is characterized in that, described cushion is quality of rubber materials.
