Abstract

The utility model relates to a screw bolt and screw nut fastening element, which comprises a screw bolt and a screw nut, wherein the screw bolt is formed by connecting a screw bolt head and a screw rod, the tail end of the screw rod of the screw bolt is provided with a first groove, second grooves are arranged on the screw nut, the first groove and the second grooves are aligned, a pin block for preventing the screw nut from rotating is arranged in the first groove, the width of the first groove and the width of the second grooves are equal, and at least two second grooves are arranged on the screw nut. The screw bolt and screw nut fastening element provided by the utility model has the advantages that because the first groove is arranged at the tail end of the screw rod of the screw bolt, the second grooves are arranged on the screw nut, the pin block is inserted when the first groove and the second grooves are aligned, the screw nut can be prevented from being disengaged from the screw bolt through unscrewing via vibration, the work performance and the work stability of machinery are enhanced, and the occurrence rate of personnel accidents is reduced.

Description

A kind of bolt and nut fastening piece
Technical field
The utility model relates to a kind of bolt and nut fastening piece, and particularly a kind of nut that can prevent belongs to be fastenedly connected the part technical field because of the vibration turn breaks away from the bolt and nut fastening piece of bolt.
Background technique
Bolt is by head and screw rod (having externally threaded cylindrical body) one type of fastening piece dimerous, and common and nut is used, and is used to be fastenedly connected two mechanical parts that have through hole.But because some high-strength mechanical can produce violent vibration in the process of day-to-day operation; Nut is loosening easily; Again owing to of the carelessness of present enterprise for maintenance of machine; Can make nut break away from bolt after long-time the use, the service behaviour and the working stability of influence machinery have the hidden danger that human injury takes place.
The model utility content
The utility model purpose is to provide a kind of nut that can prevent to break away from the bolt and nut fastening piece of bolt because of the vibration turn for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of bolt and nut fastening piece, comprise screw bolt and nut, and said bolt is connected to form by bolt head and screw rod, and the screw rod tail end of said bolt has the groove I; Have the groove II on the said nut; After said groove I and the alignment of groove II, be provided with the pin block that prevents that nut from rotating in the said groove I.
Preferably, the width of said groove I and groove II equates.
Preferably, have two groove II on the said nut at least.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The bolt and nut fastening piece of the utility model; Because the screw rod tail end of bolt has the groove I, has the groove II on the nut, after groove I and the alignment of groove II; Insert pin block; Can prevent that nut from because of the vibration turn breaks away from bolt, having increased mechanical service behaviour and working stability, reduce the human injury odds.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the bolt and nut fastening piece of the utility model;
Accompanying drawing 2 is the stereogram of the bolt and nut fastening piece of the utility model;
Wherein: 1, bolt; 2, nut; 3, bolt head; 4, screw rod; 5, groove I; 6, groove II; 7, pin block.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of bolt and nut fastening piece of the utility model shown in accompanying drawing 1-2 comprises bolt 1 and nut 2, and said bolt 1 is connected to form by bolt head 3 and screw rod 4, and screw rod 4 tail ends of said bolt 1 have groove I 5; Have groove II 6 on the said nut 2; Said groove I 5 is provided with the pin block 7 that prevents that nut from rotating after aliging with groove II 6 in the said groove I 5; The width of said groove I 5 and groove II 6 equates; At least have two groove II 6 on the said nut 2.
During use, earlier bolt 1 is inserted in the positioning hole, screw on nut 2 then, after groove I 5 and groove II 6 were alignd, tool using inserted pin block 7.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The bolt and nut fastening piece of the utility model; Because the screw rod tail end of bolt has the groove I, has the groove II on the nut, after groove I and the alignment of groove II; Insert pin block; Can prevent that nut from because of the vibration turn breaks away from bolt, having increased mechanical service behaviour and working stability, reduce the human injury odds.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
