In order to solve the problems, such as screw retention, occur various self-locking nuts in existing Investment in fastener industry,
Complicated, production cost is high, and installs inconvenience, and anti-loosing effect is undesirable.In addition, the work of existing self-locking nut is former
Reason is all the screw thread of nut or screw pitch to be made to generate distortion variation using external force, to obtain additional pretightning force, reaches anti-and uncages
Tight purpose.However, this mode not only make screw be screwed into torque increase, but also be twisted destruction screw thread or screw pitch without
Method is restored, and causes the nut after use or screw that cannot reuse, waste of resource.
Utility model content
In order to solve the above-mentioned technical problem, a kind of locking self-locking fastener of the offer of the utility model, can not only reach
The purpose of anti-loosening locking, and any damage is not caused to the screw after using and swivel nut, screw and swivel nut still can be after
It is continuous to use, it is cost-effective.
What the utility model was formed by：A kind of locking self-locking fastener, including screw, swivel nut, the first connector with
And second connector, the screw is made of head of screw and the screw rod being connected as one with head of screw, in the bar portion of screw rod
On be provided with right-handed thread, the swivel nut is made of round set and the thread bush being connected as one with round set, in screw thread
Left hand thread is provided on the outer wall of set, in the perforative through-hole that is provided centrally with of swivel nut, screw rod is passed through out of through-hole and screw rod
Thread bush end is stretched into, the head of screw is movably connected with circle set, makes screw and swivel nut formation one can phase
To the siamese part that rotates but can not separate；Centre bore is provided on the first connector, step is provided on the second connector
Hole is respectively arranged with the right-handed thread hole coordinated with the right-handed thread of screw rod and the left hand thread with thread bush on stepped hole
The left handed threaded hole of cooperation, after the centre bore of siamese part from the first connector is pierced by, the right-handed thread of screw rod and the second connector
On right-handed thread hole be threadedly coupled, the left hand thread of thread bush is threadedly coupled with the left handed threaded hole on the second connector.
Further, annular cone tank is offered on the end face of the head of screw, is provided on the end face of circle set and circle
The taper sheath that shape set is connected as one, taper sheath are fitted in annular cone tank and can not exit, so as to make head of screw and circle
Set is movably connected, and then screw and swivel nut is made to form a siamese part that can be relatively rotated but can not separate.
Further, the oral area outer rim of the taper sheath is provided with rounded corners.
Further, the right-handed thread is identical with the screw pitch of left hand thread, so as to enable screw and swivel nut synchronous rotary,
Ensure screw and swivel nut can synchronize be threaded in or out the second connector.
By adopting the above-described technical solution, the utility model has the advantage of：The utility model uses the phase of siamese part
Mutual restraining function and mutual barrier effect achieve the purpose that anti-loosening locking, not only easy to assembly, but also to the screw after using
Any damage is not caused with swivel nut, screw and swivel nut still can be continuing with, cost-effective.Therefore, the utility model is prevented
Loose locking effect is good, and simple in structure, and manufacture is at low cost, convenient for mass production.

Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
The embodiment of the utility model：As shown in Figures 1 and 2, the locking self-locking fastener of the utility model, including spiral shell
Nail, swivel nut, the first connector 3 and the second connector 4, the screw are connected as one by head of screw 1 and with head of screw 1
Screw rod 9 form, be provided with right-handed thread 5 in the bar portion of screw rod 9, the swivel nut connects by circle set 2 and with circle set 2
Be connected in integrated thread bush to form, left hand thread 8 be provided on the outer wall of thread bush, swivel nut be provided centrally with it is perforative
Through-hole 10, screw rod 9 is passed through out of through-hole 10 and screw rod 9 stretches into thread bush end, and annular is offered on the end face of the head of screw 1
Cone tank 12, is provided with the taper sheath 13 being connected as one with round set 2 on the end face of round set 2, and taper sheath 13 is fitted in
It can not be exited in annular cone tank 12, so as to which head of screw 1 be made to be movably connected, and then make screw and spiral shell with circle set 2
