Description of the drawings
Fig. 1 is the structural representation of this utility model one embodiment.
Fig. 2 is the A in Fig. 1 to schematic diagram.
Fig. 3 is the structural representation of PT cabinet cable chamber doors.
Specific embodiment
As shown in Figure 1 and Figure 2, this on-load that the present embodiment is provided switchs the grounding interlocking device of PT cabinets, including pedestal
1st, first line of a couplet action-oriented seat 2, interlocking circular shaft 3, yoke plate 4, rubber hose 5, protection sleeve pipe 6, holding screw 7, the check washer 8, second line of a couplet
Action-oriented seat 9, switch circular shaft 10.
It is used as connector by rubber hose 5 between first line of a couplet action-oriented seat 2 and second line of a couplet action-oriented seat 9 to be connected as a single entity, rubber
There is protection sleeve pipe 6 outside flexible pipe 5, protect the length of sleeve pipe 6 less than the length of rubber hose 5.Interlocking circular shaft 3 is vertically connected at the first line of a couplet
Stretch out along its upside on action-oriented seat 2, the lower end of yoke plate 3 is connected on interlocking circular shaft 3, the operating shaft of upper end and earthed switch connects
It is integrated, makes interlocking circular shaft 3 and yoke plate 4 form linkage component.
Switch circular shaft 10 is vertically connected on second line of a couplet action-oriented seat 9 past its downside and stretches out as switch gate component.
Offer on two guide holders and have the length protection sleeve pipe 6 shorter than rubber hose outside draw-in groove, rubber hose 5, rubber is soft
Two ends are inserted respectively in the draw-in groove on corresponding guide holder after pipe 5 bends, and are then fastened by check washer 8 and holding screw 7.Protect
Protecting pipe 6 is also adopted by rubber tube, card ear is arranged on pedestal 1 and blocks at the two ends for protecting sleeve pipe 6, makes the rubber hose 5 can be along protection
Sleeve pipe 6 slides.
The top of pedestal 1 opens up rectangle chute 11 in the horizontal direction, and first line of a couplet action-oriented seat 2 is installed on rectangle chute 11
Place, the both sides of first line of a couplet action-oriented seat 2 have the chute can be along the sliding of rectangle chute 11 or so.
The middle cross beam of PT cabinets is installed in the horizontal direction, when this grounding interlocking device is installed, pedestal 1 is fixed in PT cabinets
The upside of crossbeam, makes the rectangle chute on first line of a couplet action-oriented seat top positioned at the inner side of middle cross beam, the correspondence pedestal on middle cross beam
