Plate 2.1 contacts, and the fixed block 8.2 and fixed plate 6 are fixed.By using above-mentioned technical proposal, when needing to lock protective plate 2
When, 2.1 inner wall of lockplate compresses telescopic block 8.1, and telescopic block 8.1 is retracted into mounting hole 6.2, when user releases 44 He of latch fitting
After the locking of lockplate 2.1, telescopic block 8.1 pops up under the action of compressed spring 8.3, and lockplate 2.1 is flicked.
The mounting hole 6.2 is arranged near fore shaft 2.2 close to 4 side of latch fitting.By using above-mentioned technical proposal, work as lock
When part 4 is in the unlocked position, that is, when being in 2.2 position of fore shaft, after protective plate 2 pops up, elastic male member 8 stretches out, and extension elongation
Greater than 2 thickness of protective plate, the sticking department 4.3 of latch fitting 4 is by elastic 8 card resistance of male member, shifting of the latch fitting 4 without normal direction far from 5 direction of main shaft
Dynamic, the slide section 4.1 on latch fitting 4 is in gap 5.2, and main shaft 5 can not rotate, and is guaranteed when protective plate 2 is opened, 5 nothing of main shaft
Method rotation, electric brake 9 can not power on, and guarantee the safety of operator.
It further include multiple hinges 10, it is hinged by hinge 10 between the protective plate 2 and lower cabinet body 1.By using above-mentioned
Technical solution, protective plate 2 are realized hinged with ring network cabinet body by 10 structure of hinge, and structure is simple, convenient to carry out.
Embodiment 2
As shown in Fig. 5, Fig. 6 and Fig. 7, on the basis of embodiment 1, the lockplate 2.1 is equipped with bolt hole 2.1.1, under
Cabinet body 1 is equipped with fixed plate 6, and the fixed plate 6 is equipped with threaded hole 6.1, and threaded hole 6.1 is equipped with and 6.1 screw thread of threaded hole
The fixing bolt 7 of cooperation, the fixing bolt 7 pass through bolt hole 2.1.1, and fixing bolt 7 compresses lockplate 2.1.By adopting
With above-mentioned technical proposal, after latch fitting 4 locks protective plate 2, user can by 7 fixed protection plate 2 of fixing bolt, with reach into
The purpose of one step fixed protection plate 2.
The bolt hole 2.1.1 is strip-shaped hole.There are errors in size in processing for protective plate 2 and lockplate 2.1, can
The case where 7 difficulty of fixing bolt is worn can occur, and open up strip-shaped hole on lockplate 2.1, then convenient for operator according to reality
Situation is adjusted.
By using the present invention, when needing Maintenance and Repair executing agency, user will be in handle insertion operation hole 3.1.2
To rotate main shaft 5 to earthing position, at this time then 5.1 gap 5.2 of lantern ring pushes latch fitting 4 to 5 side of main shaft against sliding slot 3.1.1
To movement, 3.1.1 is mobile along the chute for slide section 4.1, into handle hole 3.1.2 and is caught in gap 5.2, sticking department 4.3 moves at this time
It moving to 2.2 position of fore shaft, sticking department 4.3 no longer compresses lockplate 2.1, so that the unlock operation of latch fitting 4 Yu protective plate 2 is completed,
Lockplate 2.1 is received elastic male member 8 and is bounced at this time, and protective plate 2 is opened.After elastic male member 8 bounces, 4.3 quilt of sticking department of latch fitting 4
The slide section 4.1 of 8.1 card resistance of telescopic block, movement of the latch fitting 4 without normal direction far from 5 direction of main shaft, latch fitting 4 is in gap 5.2, main
Axis 5 can not rotate, and guarantee that main shaft 5 can not power on, and guarantee the safety of operator when protective plate 2 is opened.It will be at ring network cabinet
