Abstract
The invention discloses a bolt and nut fastener which comprises a bolt and a nut. The bolt is formed by connecting of a bolt head and a screw. A groove I is formed at the tail end of the screw of the bolt. Grooves II are formed in the nut. After the groove I and the grooves II are aligned, a pin block for preventing the nut from rotating is arranged in the groove I. The width of the groove I is equal to the width of each groove II. The nut is provided with at least two grooves II. Due to the facts that the groove I is formed at the tail end of the screw, and the grooves II are formed in the nut, after the groove I and the grooves II are aligned, the pin block is inserted into the groove I to prevent the nut from separating from the bolt because of vibration and rotation, work property and work stability of a machine are increased, and probability of human injuries is reduced.
Description
Technical field
The present invention relates to a kind of bolt and nut fastening piece, particularly a kind ofly can prevent that nut breaks away from the bolt and nut fastening piece of bolt because of the vibration turn, belong to be fastenedly connected the part technical field.
Background technique
Bolt is by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, and common and nut is used in conjunction with, and is used for being fastenedly connected two with the mechanical parts of through hole.But because some high-strength mechanical can produce violent vibration in the process of day-to-day operation, nut is easily loosening, again due to the carelessness of present enterprise for maintenance of machine, can make nut break away from bolt after long-time the use, service behaviour and the working stability of impact machinery have the hidden danger that human injury occurs.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind ofly can prevent that nut breaks away from the bolt and nut fastening piece of bolt because of the vibration turn.
Technical solution of the present invention is achieved in that a kind of bolt and nut fastening piece, comprises screw bolt and nut, and described bolt is connected to form by bolt head and screw rod, and the screw rod tail end of described bolt has the groove I; Have the groove II on described nut; After described groove I and the alignment of groove II, be provided with the pin block that prevents nut rotation in described groove I.
Preferably, the width of described groove I and groove II equates.
Preferably, have at least two groove II on described nut.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Bolt and nut fastening piece of the present invention, because the screw rod tail end of bolt has the groove I, have the groove II on nut, after groove I and the alignment of groove II, insert pin block, can prevent that nut from because 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, technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of bolt and nut fastening piece of the present invention;
Accompanying drawing 2 is the stereogram of bolt and nut fastening piece of the present invention;
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, the present invention is described.
Be depicted as a kind of bolt and nut fastening piece of the present invention as accompanying drawing 1,2, comprise bolt 1 and nut 2, described bolt 1 is connected to form by bolt head 3 and screw rod 4, and screw rod 4 tail ends of described bolt 1 have groove I 5; Have groove II 6 on described nut 2; After described groove I 5 and 6 alignment of groove II, be provided with the pin block 7 that prevents nut rotation in described groove I 5; The width of described groove I 5 and groove II 6 equates; At least have two groove II 6 on described nut 2.
During use, first bolt 1 is inserted in positioning hole, then screw on nut 2, after groove I 5 and 6 alignment of groove II, tool using inserts pin block 7.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Bolt and nut fastening piece of the present invention, because the screw rod tail end of bolt has the groove I, have the groove II on nut, after groove I and the alignment of groove II, insert pin block, can prevent that nut from because the vibration turn breaks away from bolt, having increased mechanical service behaviour and working stability, reduce the human injury odds.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
