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 cause coming off from bolt, 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 the screw bolt and nut being threaded, described bolt comprises head and screw rod, also comprise anti-skidding assembly, the periphery of described screw rod axially offers along it grooving that cross section is rectangle, described anti-skidding assembly comprises for being placed on anti-falling piece in grooving, for anti-falling piece being fixed on to the nut for subsequent use in grooving, described fastener comprises the fixing rod that is placed in grooving and lever for inconsistent with the another side of the relative head of nut for subsequent use, and one end of described fixing rod is fixedly connected with lever.
By adopting technique scheme, after the part that is threaded hole is connected with screw flight, part is fixed with nut, bolt for subsequent use and screw rod are threaded connection, nut for subsequent use is arranged on nut and is relatively threaded the other end of the part in hole, then anti-falling piece is placed in grooving, bolt counterrotating for subsequent use is pushed down the fixing rod in grooving and is conflicted and be connected with lever, lever blocks the further counterrotating of bolt for subsequent use, play Drop-proof effect, when being given a shock, part occurs when loosening, baffle plate and nut for subsequent use coordinate prevention part to come off, therefore, this model utility has simple in structure, the feature of Drop-proof.
The utility model is further set to: the other end of the relative head of described fixing rod is L-type with lever and is fixedly connected with.
By adopting technique scheme, be the anti-falling piece that L-type is fixedly connected with, simple in structure, easily manufactured, when baffle plate and nut for subsequent use are inconsistent, baffle plate contacts with nut surface for subsequent use, on the one hand, and anticreep better effects if, on the other hand, the moment of torsion producing between baffle plate and fixing rod diminishes, and is not easy fracture, increases the working life of anti-falling piece.
The utility model is further set to: described lever and fixing rod joint are provided with stiffening rib.
By adopting technique scheme, the part vibrations extruding nut for subsequent use that comes off is transferred to power on lever, and lever bears excessive power or for a long time in colliding, easily rupture in lever and fixing rod joint, lever and fixing rod joint are provided with stiffening rib, increase the working life of fastener.
The utility model is further set to: the thickness of described fixing rod is less than or equal to the degree of depth of grooving, and the length of described fixing rod is less than the length of grooving.
By adopting technique scheme, the thickness of fixing rod is less than or equal to the degree of depth of grooving, reduces material, cost-saving, and the length of fixing rod is less than the length of grooving, when making fixing rod easily put into grooving, reduces costs.

In figure: 1, bolt; 11, head; 12, screw rod; 121, grooving; 2, anti-falling piece; 21, fixing rod; 22, lever; 3, nut for subsequent use, 4, stiffening rib.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of bolt assembly embodiment of the utility model is described further.
A kind of bolt 1 assembly, comprise the bolt 1 and the nut that are threaded, described bolt 1 comprises head 11 and screw rod 12, also comprise anti-skidding assembly, the periphery of described screw rod 12 axially offers along it grooving 121 that cross section is rectangle, described anti-skidding assembly comprises for being placed on the anti-falling piece 2 in grooving 121, for anti-falling piece 2 is fixed on to the nut for subsequent use 3 in grooving 121, described fastener comprises the fixing rod 21 that is placed in grooving 121 and lever 22 for inconsistent with the another side of the relative head 11 of nut 3 for subsequent use, one end of described fixing rod 21 is fixedly connected with lever 22.After the part that is threaded hole is threaded with screw rod 12, part is fixed with nut, bolt 1 for subsequent use is threaded connection with screw rod 12, nut 3 for subsequent use is arranged on nut and is relatively threaded the other end of the part in hole, then anti-falling piece 2 is placed in grooving 121, bolt 1 counterrotating for subsequent use is pushed down the fixing rod 21 in grooving 121 and is conflicted and be connected with lever 22, lever 22 blocks the further counterrotating of bolt 1 for subsequent use, play Drop-proof effect, when being given a shock, part occurs when loosening, baffle plate and nut for subsequent use 3 coordinate prevention part to come off, therefore, this model utility has simple in structure, (anti-falling piece 2 and nut for subsequent use 3 all adopt iron material to make to the feature of Drop-proof, the consistency of thickness of the length of fixing rod 21 and nut for subsequent use 3).
The other end of described fixing rod 21 relative heads 11 is L-type with lever 22 and is fixedly connected with.Be the anti-falling piece 2 that L-type is fixedly connected with, simple in structure, easily manufactured, when baffle plate and nut for subsequent use 3 are inconsistent, baffle plate contacts with 3, nut for subsequent use, on the one hand, anticreep better effects if, on the other hand, the moment of torsion producing between baffle plate and fixing rod 21 diminishes, be not easy fracture, increase the working life of anti-falling piece 2.
