Abstract
The utility model discloses a bolt assembly, which comprises a bolt and a nut which are matched with each other, wherein the bolt comprises a head part and a screw; a cutting groove communicated with the excircle face of the screw is formed in the other end face, opposite to the head part, of the screw; the cutting groove extends to the head part; an antiskid piece connected with the cutting groove in a clamping manner is arranged on the other side surface, opposite to the head part, of the nut in threaded connection with the screw. The bolt assembly disclosed by the utility model has the characteristics of simple structure and capability of falling-off prevention.
Description
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to a kind of bolt assembly.
Background technique
Bolt is by head and a screw rod class fastening piece dimerous, and bolt is the mechanical parts that connect use, and bolt is with externally threaded cylindrical body, need coordinate with nut, can dismantle.
Bolt in the market, after nut screws, can be fixed two parts that are threaded hole, still, after fixing certain hour, due to the effect of external force, usually makes nut loosening, even comes off, and makes it to lose corresponding function.
Model utility content
For prior art exist deficiency, the purpose of this utility model is to provide a kind of bolt assembly, have simple in structure, the feature of Drop-proof.
For achieving the above object, the utility model provides following technological scheme:
A kind of bolt assembly, comprise suitable screw bolt and nut, described bolt comprises head and screw rod, the other end of the relative head of described screw rod offers the grooving that is communicated with its periphery, described grooving extends to head, the another side of the relative head of nut connecting with screw flight be connected with for the Non-slip material of grooving clamping.
By adopting technique scheme, the grooving offering on the periphery of screw rod, the another side of the relative head of nut connecting with screw flight be connected with for the Non-slip material of grooving clamping, nut and bolt are fixed object, while use under vibration environment, in order to prevent that nut from coming off from screw rod in vibrations process, only the Non-slip material connecting on nut need to be connected to and groove in, nut limits its rotation by Non-slip material and the grooving of clamping, ensure that its assembling is stable, reach again the effect of anticreep, therefore, this model utility has simple in structure, the feature of Drop-proof.
The utility model is further set to: described Non-slip material is made up of the metallic material of good toughness, and its cross section is rounded.
By adopting technique scheme, Non-slip material is made up of the good metallic material of toughness, easily bending is connected in grooving and is not easy fracture, long service life, because nut and screw rod are threaded connection, nut is in rundown process, connect thereon Non-slip material be not easy fixed position, the cross section of Non-slip material is rounded, easily towards different direction bending, easy to use.
The utility model is further set to: the grooving that described Non-slip material and cross section are rectangle is equipped with three, all being radially circumferentially and being uniformly distributed, the corresponding Non-slip material of each grooving along screw rod of three groovings.
By adopting technique scheme, the Non-slip material being connected on nut is provided with three, after fastening nut, by being connected in grooving with the nearest Non-slip material bending of grooving, multiple Non-slip materials and grooving is set, on the one hand, and easier clamping; On the other hand, reduce the length of Non-slip material, the moment of torsion that can bear is larger, locking, Drop-proof better effects if, and the cross section of grooving is rectangle, and Non-slip material and grooving clamping are more stable, and Non-slip material is not easy to skid off in grooving, affects clamping effect.
Brief description of the drawings
Fig. 1 is the utility model bolt assembly embodiment's schematic diagram.
In figure: 1, bolt; 11, head; 12, screw rod; 121, grooving; 2, nut; 21, Non-slip material.
Embodiment
With reference to Fig. 1, the utility model bolt assembly embodiment is described further.
A kind of bolt assembly, comprise suitable bolt 1 and nut 2, described bolt 1 comprises head 11 and screw rod 12, the other end of described screw rod 12 relative heads 11 offers the grooving 121 that is communicated with its periphery, described grooving 121 extends to head 11, the another side of the relative head 11 of nut 2 being threaded with screw rod 12 be connected with for the Non-slip material 21 of grooving clamping.The grooving 121 offering on the periphery of screw rod 12, the another side of the relative head 11 of nut 2 being threaded with screw rod 12 be connected with for the Non-slip material 21 of grooving clamping, nut 2 is fixed object with bolt 1, while use under vibration environment, in order to prevent that nut 2 from coming off from screw rod 12 in vibrations process, only the Non-slip material 21 connecting on nut 2 need to be connected to and groove in, nut 2 limits its rotation by Non-slip material 21 and the grooving 121 of clamping, ensure that its assembling is stable, reach again the effect of anticreep, therefore, this model utility has simple in structure, the feature of Drop-proof.
Non-slip material 21 its cross sections of being made up of the good metallic material of toughness are rounded.Non-slip material 21 is made up of the good metallic material of toughness, easily bending is connected in grooving 121 and is not easy fracture, long service life, because nut 2 is threaded connection with screw rod 12, nut 2 is in rundown process, connect thereon Non-slip material 21 be not easy fixed position, the cross section of Non-slip material 21 is rounded, easily towards different direction bending, it is easy to use that (Non-slip material 21 is made up of metallic copper material, bolt 1 can be selected stainless steel with nut 2, copper, iron material is made, make in order to reduce costs preferential selection iron material, Non-slip material 21 adopts argon arc welding to link together with nut 2).
The grooving 121 that described Non-slip material 21 and cross section are rectangle is equipped with three, three Non-slip materials 21 and all being radially circumferentially and being uniformly distributed along screw rod 12 of three groovings 121.The Non-slip material 21 being connected on nut 2 is provided with three, after fastening nut 2, by being connected in grooving 121 with nearest Non-slip material 21 bendings of grooving 121, multiple Non-slip materials 21 and grooving 121 is set, on the one hand, and easier clamping; On the other hand, reduce the length of Non-slip material 21, the moment of torsion that can bear is larger, locking, Drop-proof better effects if, the cross section of grooving 121 is rectangle, and Non-slip material 21 is more stable with grooving 121 clampings, Non-slip material 21 is not easy to skid off in grooving 121, affects clamping effect.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technological schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
