Wall, the elastic component other end contradict the check lock lever, and the fixed seat is hinged with the arc convex, and its hinged place forms axle
The heart, after the check lock lever exits the locking slot, the resilient element urges check lock lever is rotatably inserted into the first through hole around axle center
It is interior.
Further, the check lock lever end is provided with the first bending section of the pluggable first through hole.
Further, the check lock lever is provided with the second bending section by subterminal position.
Further, diameter of the check lock lever near described second bending section one end is less than the check lock lever near described
The diameter of locking slot one end.
Further, Magnet is provided with the first through hole.
Further, the insulating bar is provided with axially arranged third through-hole.
Beneficial effects of the present invention：
Insulating bar is provided with the operation head of the present invention, operation head is fixed on action bars by insulating bar.To keep away
Exempt to operate head to separate with crane, the operation head of the present invention also includes arc convex and latch assembly, wherein, latch assembly bag
Fixed seat, check lock lever and elastic component are included, fixed seat is hinged with arc convex, its hinged place forms axle center.When check lock lever catches on order
After gram, elastic component orders about check lock lever and rotates around axle center, and after check lock lever is rotatably inserted into first through hole, crane will be fastened to action bars
On head.
Description of the drawings
Fig. 1 is the structural representation of operation head in the present invention；
Fig. 2 is structural representation of the operation head at latch assembly in the present invention (after amplification).
Specific embodiment
With reference to Fig. 1, a kind of operation head, including insulating bar 1, arc convex 2 and latch assembly, insulating bar 1 and locking group
Part is separately fixed at the week side of boss of arc convex 2, and insulating bar 1 is used for attended operation bar, and latch assembly is used to win to hang upside down in high pressure
Crane on electric wire.
See figures.1.and.2, latch assembly includes fixed seat 3, check lock lever 4 and elastic component 5.Operation head also includes connecting rod
6, connecting rod 6 is also cross fixed seat 3 and arc convex 2, to realize that fixed seat 3 is hinged with arc convex 2, the central shaft of connecting rod 6
For fixed seat 3 and the axle center of 2 hinged place of arc convex.The second through hole 31 coordinated with check lock lever 4, lock are provided with fixed seat 3
Tight bar 4 can be moved axially along the second through hole 31.5 one end of elastic component is contradicted on the side wall of arc convex 2,5 other end of elastic component
Contradict on check lock lever 4, elastic component 5 can promote check lock lever 4, check lock lever 4 be driven solid by thrust under compression
Reservation 3 is rotated around connecting rod 6.
See figures.1.and.2, the centre position of arc convex 2 is provided with first through hole 21, and check lock lever 4 is rotated around connecting rod 6
Afterwards, the end of check lock lever 4 is can be inserted in first through hole 21, and the side wall of arc convex 2 is provided with axially arranged locking slot 22, lock
The top of tight bar 4 is can be inserted in locking slot 22, to avoid check lock lever 4 from rotating.
See figures.1.and.2, the operation principle of the present embodiment：First, insulating bar 1 is arranged on action bars；Then, no
Offset moves action bars, catches on crane in order to check lock lever 4；Finally, after check lock lever 4 catches on crane, pulling operation bar makes locking
The top of bar 4 is exited from locking slot 22, and in the state of check lock lever 4 is separated with locking slot 22, check lock lever 4 is rotated around connecting rod 6,
So that in the end insertion first through hole 21 of check lock lever 4, so as to realize that check lock lever 4 fixes crane.
With reference to Fig. 2, it is to realize that the end of check lock lever 4 is provided with the first bending section in the insertion first through hole 21 of check lock lever 4
41, check lock lever 4 is inserted in first through hole 21 by the first bending section 41.
With reference to Fig. 2, be to realize that check lock lever 4 catches on crane, the second bending is provided with check lock lever 4 is by subterminal position
Section 42, check lock lever 4 defines a draw-in groove 43 at the second bending section 42, after crane insertion draw-in groove 43, cable maintenance workman
Pulling operation bar, is separated with locking slot 22 with realizing that check lock lever 4 is moved up.To increase the connection of check lock lever 4 and locking slot 22
Intensity, in the present embodiment, check lock lever 4 makes tapered rod, and specifically, diameter of the check lock lever 4 near 42 one end of the second bending section is little
In check lock lever 4 near 22 one end of locking slot diameter, this structure is capable of achieving check lock lever 4 and 22 interference fit of locking slot.
In the present embodiment, check lock lever is tapered rod, in addition to it can increase the bonding strength of check lock lever and locking slot, tapered
The most important effect of bar is to limit the distance that check lock lever is moved along the second through hole, to avoid check lock lever displacement mistake
Greatly, so that the first bending section of check lock lever cannot be inserted in first through hole.
Cause the first bending section insert in first through hole to avoid check lock lever displacement excessive, the present embodiment
In, the diameter of first through hole is far longer than the width of the first bending section, and this structure realizes the first bending section with first through hole
Coordinate.But, this structure also brings hidden danger, and after the first bending section insertion first through hole, check lock lever is to be in elastic component
Detached state, it means that arc convex is easy for logical from first towards there is reversion or inclination, the first bending section
Exit in hole.To solve this problem, in the present embodiment, Magnet is provided with first through hole, and (certainly, corresponding first bending section is
Ironwork), to avoid the first bending section after arc convex occurs radial rotary, exit from first through hole.
With reference to Fig. 1, it is to realize that insulating bar 1 is connected with action bars, is provided with the axial direction of insulating bar 1 and coordinates with action bars
Third through-hole 11.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and is familiar with
Those skilled in the art should be understood that the present invention includes but is not limited to accompanying drawing and the content described in specific embodiment above.
The modification of any function and structure principle without departing from the present invention is intended to be included in the scope of claims.
