Description
【Technical field】
The utility model is related to the technical field of securing member, the technology neck of particularly a kind of nut with locking function
Domain.
【Background technology】
Screw bolt and nut is common securing member, traditional nut typically without fastening locking functions, due to a lot of spiral shells
Screw bolt and nut is all to use on machine, and after start machine, machine can occur a little vibrations, therefore when screw bolt and nut uses
Long, nut will come loose or even depart from bolt, cause important impact thus can to the normal operation of machine.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposing a kind of spiral shell with locking function
Mother, the utility model by adopting the locking mode that nut, spiral metal wire and pad three match, such that it is able to effective
Prevent screw bolt and nut because of long machine vibration, and cause nut to come loose, and then increased the lock ability of nut.
For achieving the above object, the utility model proposes a kind of nut with locking function, golden including nut, spiral
Belong to silk and pad, one end of described spiral metal wire is directly anchored on pad, and the other end of described spiral metal wire is directly inserted
To in nut, described nut includes nut body, centre bore and spiral through hole, and described nut body offers centre bore and spiral shell
Rotation through hole, described centre bore includes threaded bore portions and circular hole part, the hand of spiral of described spiral metal wire and nut check
In opposite direction, when nut is not locked, the other end of described spiral metal wire can not reach in centre bore, described spiral lead to
The one end in hole is opened on nut bottom surface, and the other end of described spiral through hole is directly connected with the circular hole part of centre bore.
Preferably, the depth of described circular hole part is not more than the 1/4 of nut depth of center hole, described spiral metal wire
Diameter should be less than the pitch of bolt thread used.
The beneficial effects of the utility model：The utility model is by adopting nut, spiral metal wire and pad three's phase
The locking mode of cooperation, such that it is able to effectively prevent screw bolt and nut because of long machine vibration, and causes nut to come loose,
And then increased the lock ability of nut.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
【Brief description】
Fig. 1 is a kind of structural representation of the nut with locking function of the utility model；
Fig. 2 is a kind of top view of the nut with locking function of the utility model；
Fig. 3 is the sectional view of the utility model nut；
In figure：1- nut, 2- spiral metal wire, 3- pad, 11- nut body, 12- centre bore, 13- spiral through hole,
121- threaded bore portions, 122- circular hole part.
【Specific embodiment】
Refering to Fig. 1-3, the utility model is a kind of nut with locking function, including nut 1, spiral metal wire 2 and
Pad 3, one end of described spiral metal wire 2 is directly anchored on pad 3, and the other end of described spiral metal wire 2 is directly inserted into
In nut 1, described nut 1 includes nut body 11, centre bore 12 and spiral through hole 13, during described nut body 11 offers
Heart hole 12 and spiral through hole 13, described centre bore 12 includes threaded bore portions 121 and circular hole part 122, described circular hole part 122
Depth be not more than nut centre bore 12 depth 1/4, the diameter of described spiral metal wire 2 should be less than the spiral shell of bolt thread used
Away from, the hand of spiral of described spiral metal wire 2 is in opposite direction with what nut 1 was locked, when nut 1 is not locked, described spiral gold
The other end belonging to silk 2 can not reach in centre bore 12, and one end of described spiral through hole 13 is opened on nut 1 bottom surface, institute
The other end stating spiral through hole 13 is directly connected with the circular hole part 122 of centre bore 12.
The course of work of the present utility model
The utility model be a kind of nut with locking function in the course of the work, first by the one of spiral metal wire 2
End is inserted in spiral through hole 13, then nut 1, spiral metal wire 2 and pad 3 is inserted in bolt used, locks in nut 1
During, due to the rotation of nut 1, spiral metal wire 2 will pass from the other end of spiral through hole 13, thus snapping into used
Between screw bolt and nut 1, and then play the effect of locking nut.
The utility model by adopting the locking mode that nut, spiral metal wire and pad three match, thus can
Effectively to prevent screw bolt and nut because of long machine vibration, and cause nut to come loose, and then increased the locking of nut
Ability.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
