Description of the drawings
Fig. 1 is a kind of locked connector connection status structure chart proposed by the present invention;
Fig. 2 is the locking state structure chart of Fig. 1;
Fig. 3 is nut sectional view in Fig. 1.
Specific implementation mode
Referring to Fig.1, a kind of locked connector proposed by the present invention, including:Bolt, nut 1, cylinder 2 and inserted link 3.
Bolt is made of the screw rod 4 being fixedly connected and head 5, and screw rod 4 is internally provided with the first cylindrical cavity 4-1, the first cylinder
Chamber 4-1 runs through end face of the screw rod 4 far from head, and inserted link 3 is mounted in the first cylindrical cavity 4-1 and positioned at the first cylindrical cavity 4-1's
On central axis.The central axis of first cylindrical cavity 4-1 is overlapped with the central axis of screw rod 4.
Nut 1 is threadedly coupled with screw rod 4, cylinder 2 be mounted on nut 1 threaded hole 1-1 in, the central axis of cylinder 2 with
The central axis of threaded hole 1-1 overlaps.The outer diameter of cylinder 2 be less than or equal to the first cylindrical cavity 4-1 internal diameter, inserted link 3 it is external
Circular diameter is less than the internal diameter of cylinder 2.In this way, nut 1 is under 4 screw thread rotation connection status of screw rod, screw rod 4 is inserted into threaded hole 1-1
Afterwards, cylinder 2 is inserted into the first cylindrical cavity 4-1, and inserted link 3 is inserted into 2 inner ring of cylinder.
On 2 inner wall of cylinder groove 2-1, one end hinge of the inserted link 3 far from head 5 are equipped with close to one end of the bottoms threaded hole 1-1
It connects and quarter butt 6 is installed.Under natural conditions, the angle between inserted link 3 is maximum, and the maximum angle is less than or equal to for quarter butt 6
90 degree.Quarter butt 6 is resisted against in the state of 2 inner wall of cylinder, the angle between inserted link 3 be less than quarter butt 6 under natural conditions with insert
Angle between bar 3.In this way, when inserted link 3 is inserted into cylinder 2, quarter butt 6 is extruded towards inserted link 3 and rotates, so that inserted link 3 is suitable
Profit is inserted into cylinder 2;In nut 1 and 4 relative rotation fastener cycle of screw rod, inserted link 3 gradually gos deep into cylinder, until quarter butt 6 is passing through
When crossing groove 2-1, groove 2-1 is inserted under deformation restitution, to limit the relative rotation of nut 1 and screw rod 4, to nut
1 carries out screens, prevents nut 1 from being taken off from screw rod 4 and moves back.
Specifically, in present embodiment, it is equipped with torsional spring between quarter butt 6 and inserted link 3, quarter butt 6 is realized will pass through torsional spring
It resets, so that quarter butt 6 is inserted into groove 2-1.When it is implemented, also can realize quarter butt by spring or other elastic constructions
6 reset.
In present embodiment, end face of the inserted link 3 far from head 5 is equipped with baffle 7, and baffle 7 is mounted on to be grown perpendicular to inserted link 3
It spends in the plane in direction, quarter butt 6 is resisted against under natural conditions on baffle 7.7 circumscribed circle diameter of baffle is less than 2 internal diameter of cylinder.Such as
This, is further ensured that quarter butt 6 is inserted into the stability of groove 2-1 by baffle 7, prevents 6 inordinate rotation of quarter butt from being exited from groove,
To ensure nut 1 and bolt composition connector stabilization.
In present embodiment, groove 2-1 length directions are parallel to 2 central shaft of cylinder, to improve groove 2-1 to 6 turns of quarter butt
Dynamic restriction effect, to prevent nut from being relatively rotated with screw rod.
The locked connector that present embodiment provides, sets that there are two groove 2-1, two groove 2-1 to be located on 2 inner wall of cylinder
On same plane by 2 central axis of cylinder, retaining is carried out to nut to ensure that quarter butt 6 is smoothly inserted into arbitrary groove 2-1.Tool
When body is implemented, 3 end of inserted link corresponds to two groove 2-1 and is respectively equipped with a quarter butt 6, and the rotary motion trace of two quarter butts 6 is located at together
In one plane.In this way, nut 1 is with 4 relative rotational motion of screw rod, two quarter butts 6 are inserted into corresponding groove 2-1 respectively, into
One step improves the effect of preventing nut 1 from rotating.
In present embodiment, cylinder 2 is integrally formed with nut 1, and screw rod 4, head 5 and inserted link 3 are integrally formed, to improve spiral shell
The fastening that cap is connected with screw rod.
The above, preferable specific implementation mode only of the present invention, but protection scope of the present invention not office
Be limited to this, any one skilled in the art in the technical scope disclosed by the present invention, the technique according to the invention
Scheme and its inventive concept are subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
