Abstract
The utility model belongs to the technical field of fasteners, and particularly relates to a bolt additionally provided with a ring. The bolt comprises a screw cap and a screw rod, wherein the protruding round ring is arranged on the end face of the connection position between the screw cap and the screw rod, the round ring encircles the screw rod, and an annular groove is formed between the round ring and the screw rod; the center line of the groove, the center line of the round ring, the center line of the screw cap and the center line of the screw rod are located at the same axis. The round ring of the bolt prevents the screw rod from being harmed by other parts, increases the locking capacity, has the effect of fixing and reinforcing a device and enables other parts making contact with the bolt not to loosen easily in a special space; and the bolt is efficient and durable due to the fact that the round ring is additionally arranged.
Description
Technical field
The utility model belongs to technical field of fastening, refers in particular to a kind of collar bolt that adds.
Background technique
Existing technology is exactly common screw, its HEX HEAD CAP SCREWS is emitted with this one side of screw thread post smooth smooth, and such inferior position is that processing technology is coarse, and screw thread post bottom may have physical injury in course of working, cause the whole torsion of screw inadequate, stability is not all right.And the screw of this type is most of to be used in the specific parts of auto parts and components, this face between Bright Mild Steel Hexagonal Nuts and the screw thread post is to be in smooth smooth face, frictional force between screw and the parts is very little, relaxation effect is poor, cause like this stability between screw and the parts inadequate, and may cause skidding, directly or indirectly cause screw stability not, and cause the parts damages that contact.Tapped hole on using bolt and machine cooperates when locking component, lock again component after generally will overlapping first upper gasket, the elastic force of dependence packing ring increases the frictional force of the screw thread on the bolt, and then prevent the loosening of bolt, although this method can well play the effect of screw retention, also there is a deficiency, that is exactly before screwing on bolt, to overlap upper gasket at bolt first, use so just cumbersome.
Summary of the invention
The purpose of this utility model provides frictional force and the stability between a kind of effective increase bolt and parts, improves the collar bolt that adds of lock ability.
The purpose of this utility model is achieved in that a kind of collar bolt that adds, and comprises nut and screw rod, wherein, is provided with protruding circular ring on the end face of described nut and screw rod joint, and described annulus also and between screw rod forms annular groove around screw rod.
According to a kind of collar bolt that adds of the above, wherein, the centerline of described groove, annulus, nut and screw rod is on same axis.
According to a kind of collar bolt that adds of the above, wherein, described nut is the outer-hexagonal shape.
According to a kind of collar bolt that adds of the above, wherein, described screw rod end is provided with screw thread.
According to a kind of collar bolt that adds of the above, wherein, described nut and screw rod adopt stainless steel material to be made.
The utility model compared to existing technology outstanding and useful technique effect is: this protruding circular ring plays the effect that prevents that screw rod from being injured by miscellaneous part, the pad that is equivalent to increase, increased lock ability, play the fixedly effect of reinforcing device., so that other component that contact with its bolt are worked and are difficult for loosening in specific space; The annulus that increases is efficient, durable by bolt.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is front view of the present utility model;
Among the figure: 10-nut, 11-screw rod, 12-annulus, 13-groove.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3: a kind of collar bolt that adds, comprise nut 10 and screw rod 11, wherein, be provided with protruding circular ring 12 on the end face of described nut 10 and screw rod 11 joints, described annulus 12 is around screw rod 11 and and 11 formation of screw rod annular groove 13.
According to a kind of collar bolt that adds of the above, wherein, the centerline of described groove 13, annulus 12, nut 10 and screw rod 11 is on same axis.
According to a kind of collar bolt that adds of the above, wherein, described nut 10 is the outer-hexagonal shape.
According to a kind of collar bolt that adds of the above, wherein, described screw rod 11 ends are provided with screw thread.
According to a kind of collar bolt that adds of the above, wherein, described nut 10 and screw rod 11 adopt stainless steel material to be made.
Annulus 12 plays the effect that prevents that screw rod 11 from being injured by miscellaneous part in the utility model, the pad that is equivalent to increase, increased lock ability, played the fixedly effect of reinforcing device., so that other component that contact with its bolt are worked in specific space and are difficult for loosening; The annulus 12 that increases makes bolt efficient, durable.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
