As.Publication number CN201934451 U patent discloses a kind of Telescopic rod locking structure, includes an outer rod tube；Rod tube in one, one
End is socketed with outer rod tube, and a relative linear displacement is carried out with outer rod tube；One collar, collar have an epimere portion and a hypomere portion,
Epimere portion is fixedly arranged on outer rod tube, and hypomere portion coats the outer rod tube and interior frame pipe sleeve connects place, and a pulling piece, has one to pull
Portion and at least an articulated section, hypomere portion are provided with an opening and an at least trunnion mount；And the articulated section of pulling piece is pivotally connected with trunnion mount, and
Articulated section is further provided with a protuberance, and after rotating pulling part as axle using articulated section, protuberance screws in opening.On expansion link
Collar is set, although expansion link can be locked effectively, Telescopic rod structure can be caused complicated, and lock operation process is complicated.
Utility model content
In view of this, the purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of expansion link, as detection
The aid of instrument, it is possible to achieve quick lock in after elongation, locking is firm, simple in construction, swift to operate；And can be flexible
The angle of detecting structure is adjusted, expands detection range.
To reach above-mentioned purpose, the utility model uses following technical scheme：A kind of expansion link, including some single-unit bars
Body, spherical hinge and mounting head；The single-unit body of rod is hollow-core construction, and the single-unit body of rod sets chute, neck and sliding block；Chute is along single-unit bar
Body length direction is set, and the bending extension of chute front end forms neck, and sliding block is arranged at the opposite of chute；Sliding block and its rear end single-unit
The chute of the body of rod and the matching size of neck close；The free end of the front end single-unit body of rod sets spherical hinge and mounting head.
The angle of bend of neck and chute is 90 °.
The width of chute 2 of each section single-unit body of rod 1 is identical.
The trough width of the front end single-unit body of rod is small compared with the trough width of the rear end single-unit body of rod.
The beneficial effects of the utility model are：
Expansion link of the present utility model sets sliding block and sliding groove structure, it is possible to achieve expansion link flexibly stretches；Expansion link
Neck is set, it is possible to achieve the quick secure lock of expansion link, without setting clamping structure, the utility model in expansion link periphery
Telescopic rod structure is simple, simple operation；Expansion link sets spherical hinge and mounting head, detecting structure to be installed in mounting head, passes through
Spherical hinge adjusts and the angle of fixed detecting structure, has been significantly expanded detection range.

Embodiment
It is specific embodiment of the utility model below, the technical solution of the utility model is further described, but
The utility model is not limited to these embodiments.
Embodiment 1
A kind of expansion link, including some single-unit bodies of rod 1, spherical hinge 5 and mounting head 6.It 1 is hollow-core construction that the single-unit body of rod, which is,
The single-unit body of rod 1 sets chute 2, neck 4 and sliding block 3；Chute 2 is set along the length direction of the single-unit body of rod 1, and the external part of expansion link is
Front end, the other end are rear end, and the bending extension of the front end of chute 2 forms neck 4, and sliding block 3 is arranged at the opposite of chute 2.Sliding block 3 and its
The matching size of rear end chute 2 and neck 4 close, sliding block 3 in its back-end in the chute 2 and neck 4 of the single-unit body of rod slidably.
The free end of the front end single-unit body of rod sets spherical hinge 5 and mounting head 6, detecting structure to be installed in mounting head 6, leads to
Cross the angle that spherical hinge 5 adjusted and fixed detecting structure.
Operation principle：When elongating expansion link, the front end single-unit body of rod 1 is dragged, the cunning with the single-unit body of rod in its back-end of movable slider 3
Slided in groove 2；Expansion link stretching terminates, and since rear end, rotates the single-unit body of rod 1 successively so that sliding block 3 slips into its rear end single-unit
In the neck 4 of the body of rod, gradually locked from flexible rod rear end to front end.When packing up expansion link, since front end, single-unit is rotated successively
The body of rod 1 so that sliding block 3 skids off the neck 4 of its rear end single-unit body of rod, is gradually unlocked from expansion link front end to rear end, then
The single-unit body of rod 1 is promoted to pack up expansion link.
Embodiment 2
A kind of expansion link, it is with the difference of embodiment 1：The angle of bend of neck 4 and chute 1 is 90 °.
Embodiment 3
A kind of expansion link, it is with the difference of embodiment 1：The width of chute 2 of each section single-unit body of rod 1 is identical.
Embodiment 4
A kind of expansion link, it is with the difference of embodiment 1：The width of chute 2 of the front end single-unit body of rod 1 is compared with rear end single-unit
The width of chute 2 of the body of rod 1 is small.
Finally illustrate, above example only to illustrate the technical solution of the utility model and unrestricted, this area
Other modifications or equivalent substitution that those of ordinary skill is made to the technical solution of the utility model, without departing from this practicality
The spirit and scope of new technique scheme, it all should cover among right of the present utility model.
