Abstract
The utility model belongs to a loose-preventing fastening for locking a screw bolt and a nut. The nut of the utility model is a cap nut, and a through cavity whose diameter is larger than the diameter of an internal thread of an interface point is arranged in the cap of the cap nut; a handle hole is arranged on the wall of the through cavity, and a plug is arranged on the handle hole; a locking pin hole is arranged on the top end of the screw bolt, and an elastic cylindrical pin is installed in the locking pin hole. The detachable loose-preventing fastening has the functions of loose prevention, loss prevention, theft protection and rustiness prevention. The utility model can be disassembled easily when the utility model needs to be repaired; the utility model is especially suitable for traffic, railway tank cars, etc.
Description
The utility model belongs to a kind of securing means, refers in particular to the fastening piece that bolt or nut is had locking.
In known prior art, modal fastening piece is common screw bolt and nut, and the shortcoming of the bolt of this class routine, nut maximum is can not Drop-proof, anti-lost, anti-tamper and antitheft.Though the way that lock pin is installed in the expense hole on nuts and bolt is also arranged, can only solve anti-loose problem, can not overcome other shortcoming.
The purpose of this utility model provide a kind of can Drop-proof, anti-lost, anti-tamper and antitheft novel fastening piece.
Embodiment of the present utility model is that nut is designed to acorn nut, the internal thread of this acorn nut interface end and the outside thread of bolt coupling, in the lid of acorn nut is the cavity of diameter greater than the jointing internal thread diameter, on the cavity wall, have handling hole, have lockpin hole with the top of the bolt of acorn nut coupling, elastic cylindrical pin wherein is installed.During use bolt, nut being installed in needs fastening position, in screwing the process of acorn nut, when the handling hole that is screwed onto acorn nut is corresponding with the lockpin hole position on the bolt, from the handling hole of acorn nut, be inserted into elastic cylindrical pin in the lockpin hole of bolt, continue to screw acorn nut then, till tightening.When unscrewing acorn nut, because the two ends of the elastic cylindrical pin that has been equipped with can not screw in the internal thread of acorn nut on the bolt, and can not continue to unscrew, thereby reach Drop-proof, anti-lost and antitheft purpose.In the time must all dismantling, can from the loading hatch of acorn nut, elastic cylindrical pin be taken out from bolt.For more effective antitheft and antirust, obstruction can be installed on the handling hole of acorn nut.
The utility model has the advantages that the supporting bolt that a kind of novelty is provided, nut, it can not come off or lose, and has the antitheft and anti-function of getting rusty, when needs are dismantled, still can successfully take apart and carry out necessary M R, be a kind of scientific and reasonable for structure, novel fastening piece that purposes is wide, the utmost point has promotional value, is particularly suitable for using on communications and transportation and the Railway tank car.
Accompanying drawing is the utility model embodiment's a configuration state schematic representation.
The drawing explanation: the 1-bolt, the 2-internal thread, the 3-acorn nut, the 4-lockpin hole, the 5-elastic cylindrical pin, the 6-cavity, the 7-handling hole, 8-stops up.
Embodiment:
Now in conjunction with the accompanying drawings structure of the present utility model is described further, the internal thread 2 of acorn nut 3 interface end mates with the outside thread of bolt 1, in the lid of acorn nut 3 is the cavity 6 of diameter greater than its internal thread 2 diameters, have 2 handling holes 7 on the wall of cavity 6, install in the handling hole 7 and stop up 8, the top of bolt 1 has lockpin hole 4, and elastic cylindrical pin 5 wherein is installed.
