The radial direction of lug boss 3 offers two the first horizontally disposed grooves 5, and two first grooves 5 are on the Central Symmetry of lug boss 3, and two
The L-shaped pole 6 that can be moved left and right is separately installed with one groove 5, the yardarm of L-shaped pole 6 stretches out the lateral surface of lug boss 3, L-shaped
The montant end of pole 6 is placed in inner side, and the montant end of L-shaped pole 6 is the pyramidal structure that outside-in shrinks；
The described radial direction of lug boss 3 offers two second grooves 7 vertical with the first groove 5, and the second groove 7 is placed in
The lower section of one groove 5, two the second grooves 7 on the Central Symmetry of lug boss 3, be separately installed with two the second grooves 7 can before
The T-bar 8 moved afterwards, the yardarm of T-bar 8 be placed in the inner side of lug boss 3 and can with the montant end in contact of L-shaped pole 6, T-bar 8
The extended outside of lug boss 3 in montant end, moving inward for L-shaped pole 6 can promote T-bar 8 outside by the montant end of L-shaped pole 6
Move side；
Through hole 9 corresponding with L-shaped pole 6, the meeting mobile laterally of L-shaped pole 6 are offered in the described side wall of depressed part 4
Through through hole 9, threeth groove 10 corresponding with T-bar 8 is offered in the side wall of depressed part 4, being provided with the 3rd groove 10 can
Movable bullet block 11, the movement laterally of T-bar 8 can jack up bullet block 11.
The described lower end of lug boss 3 is cone structure, and the bottom surface of depressed part 4 is the conical surface being engaged with the lower end of lug boss 3
Structure.
Described the first groove 5 and the composition center of the second groove 7 has the structure of mandrel, the medial surface top of two L-shaped poles 6
The first spring 12 is connected to, the other end of each first spring 12 is connected to mandrel, and the medial surface of two T-bars 8 connects respectively
Be connected to second spring 13, the other end of each second spring 13 is connected to mandrel, the lateral surface of bullet block 11 through the 3rd spring 14 with
The lateral wall of 3rd groove 10 is connected.
The described upper end inner side edge of depressed part 4 is provided with the guiding groove 15 of axial direction, and the upper surface of described bullet block is circular arc
Face.
The utility model can assemble when specific as needed in arrester erecting bed to arrester, only need
Lightning arrester body 1 and lower lightning arrester body 2 in selection, and the lower end lug boss 3 of lightning arrester body 1 is placed on lower arrester
The upper end depressed part 4 of body 2, because lug boss 3 and depressed part 4 are shaft-hole match structure, and both terminations are the conical surface
Structure, in installation process, upper lightning arrester body 1 and the meeting self-centering of lower lightning arrester body 2, ensure that the two axis is in same
On bar straight line；When upper lightning arrester body 1 moves down, now in the presence of the side wall of depressed part 4, L-shaped pole 6 can inwardly receive
Contracting, now the montant end of L-shaped pole 6 can promote T-bar 8 to move laterally, and the montant end of T-bar 8 is moved farthest laterally
Position is at the lateral surface of lug boss 3, after the lower surface of lug boss 3 contacts with the bottom surface of depressed part 4, now rotates upper arrester sheet
Body 1, in rotation process, when L-shaped pole 6 is turned at through hole 9 corresponding on depressed part 4, L-shaped pole 6 can be the
Ejected in the presence of one spring 12, through depressed part 4 and the outside of depressed part 4 is stretched to, by upper lightning arrester body 1 and lower arrester sheet
Body 2 is connected as an entirety；Now T-bar 8 is also relative with the 3rd groove 10, after L-shaped pole 6 is ejected laterally, due to T-shaped
The yardarm of bar 8 departs from the montant end of L-shaped pole 6, and now T-bar 8 can shrink in the presence of second spring 13 to inner side,
And then the bullet block 11 in the 3rd groove 10 is upspring and stick into the second groove 7, lightning arrester body 1 and lower lightning arrester body in restriction
2 position, both positions are fixed with bullet block 11 by the L-shaped pole 6 in ten word directions, complete the assembling of the two
Operation.
When needing to dismantle upper lightning arrester body 1 and lower lightning arrester body 2, operating personnel are only needed L-shaped
The position that pole 6 is placed in the outside of depressed part 4 presses inward against, and moves inward L-shaped pole 6, while the inside shifting of L-shaped pole 6
It is dynamic that T-bar 8 can be promoted to move laterally, ejection bullet block 11, lug boss 3 is separated from depressed part 4, upper will can now take shelter from the thunder
Device body 1 takes out upwards, completes the dismantlement work of the two.
The utility model realizes the installation and dismounting of the two in installation process well, convenient by shaft-hole match
Be easy to the positioning of upper lightning arrester body 1 and lower lightning arrester body 2 when mounted, be easy to the two keep coaxial line, prevent the two
Inclination in installation process, and by the automatic positioning equipment of ten word directions, upper arrester can be achieved without other operation
Body 1 is fixedly connected with lower lightning arrester body 2, and fixed, when dismounting maintenance need to be carried out, convenient operation.
The utility model clever structure, effectively solve arrester scene when specifically used and be not easy to install, install
Fixation is not firm, the problem of being not easy to dismantle after installation.
