With vertically disposed first limited wall of axis of clamping part 1, it is to be understood that be open for rectangle limiting slot 11 tool there are two
The first limited wall being oppositely arranged.Fastening block 12 is additionally provided in limiting slot 11, the movable end 121 of fastening block 12 is out of limiting slot 11
It stretches out, for clamping insulator steel cap；The fixing end 122 of fastening block 12 is rotationally connected with limiting slot 11 by first rotating shaft, and
The axis of first rotating shaft and clamping part 1 is arranged in parallel, and fastening block 12 can be swung around first rotating shaft relative limit slot 11, therefore energy
Enough adapt to the insulator steel cap of different-diameter.The fixing end 122 of fastening block 12 also has the second limited wall 122a, it is preferred that tight
Gu there are two the second limited wall 122a for the tool of fixing end 122 of block 12, and two the second limited wall 122a are away from each other setting.First
Limited wall actively fits in the second limited wall 122a, i.e. the first limited wall and the second limited wall 122a are face contact and the two energy
Enough opposite slidings.When the fastening block 12 of clamping part 1 is clamped on insulator steel cap, insulator steel cap can be in the axis of clamping part 1
Pressure is generated to fastening block 12 on line direction, fastening block 12 and limiting slot 11 are face contact at this time, i.e. the first limited wall fits in
Second limited wall 122a, so the pressure that insulator steel cap generates fastening block 12 on the axis direction of clamping part 1 can be by the
Two limited wall 122a are transferred to the first limited wall, and compared to traditional closed fixture, the closed fixture of the utility model can be carried more
The insulator steel cap of weight, the fastening block 12 of the closed fixture can bear bigger pressure on the axis direction of clamping part 1 in other words
Power, and then first rotating shaft is avoided to deform by excessive external force, influence the normal use of the closed fixture.
The both ends of one of clamping part 1 are equipped with the installing handle 2 towards the extension of the lateral wall direction of clamping part 1, two peaces
The extending direction of hilt 2 is conllinear, and the end of installing handle 2 is equipped with one or more installation through-holes 21, and installing handle 2 can be used to clamp
Portion 1 is mounted on the power equipments bearing support such as power tower.Installing handle 2 is equipped with the vertically disposed spiral shell of axis with clamping part 1
Bolt 22, corresponding, the both ends of another clamping part 1 offer fastening slot 13, and bolt 22 passes through fastening slot 13 and passes through
Two clamping parts 1 are connected by the nut 3 in bolt 22 that is cooperatively connected, and are adjusted by adjusting nut 3 in the position of bolt 22
The size of the opening of two clamping parts 1, to be adapted to the insulator steel cap of different-diameter size.Further, bolt 22 passes through
Second shaft is rotationally connected with installing handle 2, and the axis of the second shaft and clamping part 1 is arranged in parallel, this enables bolt 22
It is swung around the second shaft with respect to installing handle 2, the one side wall of the fastening slot 13 on one of installing handle 2 is connected to the external world, is
There is the insulator steel cap of the different shapes of adaptation the clamping part 1 of fastening slot 13 can rotate around the axis of the clamping part 1
Certain angle is simultaneously connected to another clamping part 1, i.e., the opening of two clamping parts 1 by the cooperation of bolt 22 and nut 3
Setting is not faced, at this point, one of nut 3 is in the position and another position of nut 3 on bolt 22 on bolt 22
It sets not identical.
In order to which insulator steel cap is connected to securely on fastening block 12, the movable end 121 of fastening block 12 is equipped with clamping
Frame 14, the positive two sides of clamping frame 14 are equipped with the supporting parts 15 for support insulator steel cap, and the back side of clamping frame 14 is fixed
It is connected to the movable end 121 of fastening block 12, when clamping part 1 is held on the side wall of insulator steel cap, in each clamping frame 14
Two supporting parts 15 are connected to the side wall of insulator steel cap, therefore clamping frame 14 can firmly be connected to insulator steel cap
Lateral wall.The end of supporting parts 15 is additionally provided with the claw 151 extended towards 14 positive direction of clamping frame, due to insulator steel cap
A circle fixed ring is circumferentially equipped on lateral wall, therefore the claw 151 can be connected in the fixed ring of insulator steel cap.When
So, card slot, axis of the length direction of card slot perpendicular to clamping part 1, the fixation of insulator steel cap can be also opened up on supporting parts 15
Ring can be embedded in card slot, therefore supporting parts 15 can be bonded with insulator steel cap.
In order to increase the rigidity of installing handle 2, two reinforcing ribs 23 are additionally provided on each installing handle 2, two reinforcing ribs 23 divide
Not Wei Yu bolt 22 two sides, and reinforcing rib 23 arranges that bolt 22 is fixedly connected on second turn along the length direction of installing handle 2
The middle part of axis, the both ends of the second shaft are rotationally connected with two reinforcing ribs 23 respectively.
In conclusion the adjustable closed fixture of the utility model, the fastening block 12 on 1 inner sidewall of clamping part is for clamping absolutely
Edge steel cap adjusts the spacing of two clamping parts 1 by position of the adjusting nut 3 on bolt 22, so that the closed fixture
It can adapt to the insulator steel cap of sizes, the fixing end 122 of fastening block 12 is rotationally connected with limiting slot by first rotating shaft
11, and the second limited wall 122a in the fixing end 122 of fastening block 12 actively fits in the first limited wall of limiting slot 11,
When the fastening block 12 of the closed fixture is clamped on insulator steel cap, insulator steel cap will necessarily be in the axis direction of clamping part 1
On reaction force is applied to fastening block 12, at this time since the fixing end 122 of fastening block 12 and limiting slot 11 are face contact, i.e., first
Limited wall fits in the second limited wall 122a, therefore compared to traditional closed fixture, the adjustable closed fixture of the utility model can
Heavier insulator steel cap is carried, and also ensures that insulator steel cap applies fastening block 12 on the axis direction of clamping part 1
