Abstract
The utility model provides a kind of Dogbolt, comprises bolt countersunk head, bolt shank and screw thread.The bolt shank of this bolt has a groove at longitudinal middle part, and groove match is provided with packing.The afterbody of described packing is slightly thicker than front end.The advantage that the utility model has and good effect are: structure is simple, manufactures easy, effectively can solve the problem that nut comes off, and decrease the inconvenient phenomenon even caused the accident of the use produced because nut comes off.
Description
Technical field
The invention belongs to haberdashery and hardware field, particularly relates to a kind of Dogbolt.
Background technique
Common bolt can, because reasons such as the vibrations of object, make nut loosen gradually after fastening nut, and even last nut can come off from bolt, and impact uses and even causes the accident.Prevent nut from coming off is the problem that everybody studies always, but does not also have effective especially way at present.The invention of spring washer solves this problem to a certain extent, but under mechanical shock frequently, nut comes off and also happens occasionally.
Summary of the invention
The invention is the problem that will solve above-mentioned bolt falling, provides a kind of Dogbolt.
For solving the problems of the technologies described above, the technological scheme that the invention adopts is: a kind of Dogbolt, comprises bolt countersunk head, bolt shank and screw thread.The bolt shank of this bolt has a groove at longitudinal middle part, and groove match is provided with packing.
Further, the afterbody of described packing is slightly thicker than front end.
The advantage that the invention has and good effect are: structure is simple, manufactures easy, effectively can solve the problem that nut comes off, and decrease the inconvenient phenomenon even caused the accident of the use produced because nut comes off.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the invention.
In figure:
1, bolt countersunk head 2, bolt shank 3, screw thread
4, groove 5, packing
Embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
A kind of Dogbolt as shown in drawings, comprises bolt countersunk head 1, bolt shank 2 and screw thread 3.The bolt shank 2 of this bolt has a groove 4 at longitudinal middle part, and matching with groove 4 is provided with packing 5.
The afterbody of described packing 5 is slightly thicker than front end.
With reference to the friction factor of different materials, choose engineering plastics (ABS), rubber, wood as packing, insert in the groove of Dogbolt, the number of times that test loosens and distance, record data are also added up.
Conclusion: the friction factor of engineering plastics (ABS) is minimum, after causing that engineering plastics are inserted groove, repeatedly there occurs loosening phenomenon in an experiment.The effect of wood and rubber is better, and result is close.But wood is good as effectiveness comparison in the packing short time, and increasing progressively along with the time, the number of times occurring to loosen also increases progressively thereupon, this is because wood quality is comparatively hard, after service time is longer, the change of shape can occur wood, and retaining effect declines.Therefore, select rubber crop packing, loosening number of times is 0 time.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
Claims (2)
