Preferably, second end of first connecting rod adopts the tenon fourth of the twelve Earthly Branches to be connected with the mode that first end of first locking bar articulates; Wherein, second end of first connecting rod is a fourth of the twelve Earthly Branches end, and first end of first locking bar is that second end of tenon end or first connecting rod is the tenon end, and first end of first locking bar is a fourth of the twelve Earthly Branches end.
Preferably, second end of second connecting rod adopts the tenon fourth of the twelve Earthly Branches to be connected with the mode that first end of second locking bar articulates; Wherein, second end of second connecting rod is a fourth of the twelve Earthly Branches end, and first end of second locking bar is that second end of tenon end or second connecting rod is the tenon end, and first end of second locking bar is a fourth of the twelve Earthly Branches end.
The advantage of the utility model: simple in structure, easy to operate, pure Machine Design does not influence the work of cabinet internal unit, and does not take the operating space.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Fig. 1 is structural representation Fig. 1 of the utility model.
Fig. 2 is structural representation Fig. 2 of the utility model.
Fig. 3 is the A place enlarged drawing of Fig. 1.
1, back doorframe 11, first fixing hole 12, second fixing hole 2, Rear Door 3, rotation axis 4, rotation pulling-on piece 51, first connecting rod 52, first holder 53, first locking bar 61, second connecting rod 62, second holder 63, second locking bar.
Embodiment
Fig. 1, shown in 2 be gate interlock safeguard structure behind a kind of switch cubicle, comprising: back doorframe and the Rear Door that is embedded in the doorframe of back is characterized in that: respectively be provided with first holder and second holder in Rear Door inner face both sides; Have first locking bar that can move horizontally in first holder, first fixing hole in second end of first locking bar and the back doorframe on first edge is corresponding, and when first locking bar moves to the first fixing hole direction, its second end can be located in the fixing hole; Have second locking bar that can move horizontally in second holder, second fixing hole in second end of second locking bar and the back doorframe on second edge is corresponding, and when second locking bar moves to the second fixing hole direction, its second end can be located in the fixing hole; The centre of Rear Door runs through and is provided with a rotation axis, and first end of rotation axis is fixedly connected with rotary knob, and its second end is connected with the center fixation of rotation pulling-on piece; First end of rotation pulling-on piece is fixedly connected with first end of first connecting rod, and second end of first connecting rod and first end of first locking bar articulate; Second end of rotation pulling-on piece is fixedly connected with first end of second connecting rod, and second end of second connecting rod and first end of second locking bar articulate.
Among Fig. 3, second end of first connecting rod adopts the tenon fourth of the twelve Earthly Branches to be connected with the mode that first end of first locking bar articulates; Wherein, second end of first connecting rod is a fourth of the twelve Earthly Branches end, and first end of first locking bar is the tenon end.
Second end of second connecting rod adopts the tenon fourth of the twelve Earthly Branches to be connected with the mode that first end of second locking bar articulates; Wherein, second end of second connecting rod is a fourth of the twelve Earthly Branches end, and first end of second locking bar is the tenon end.
At closing time; The staff only need turn rotary knob clockwise; Rotary knob is through rotating shaft, and the driven rotary pulling-on piece turns clockwise, and the rotation pulling-on piece promotes first pull bar and second pull bar moves to both sides; First pull bar promotes first locking bar again and outwards moves, and second end of first locking bar is located in the fixing hole.In like manner, second pull bar promotes second locking bar again and outwards moves, and second end of second locking bar is located in the fixing hole, and is as shown in Figure 1, has realized the fixing of Rear Door like this.When opening the door, turn rotary knob counterclockwise, rotary knob is through rotating shaft; The driven rotary pulling-on piece is rotated counterclockwise; The rotation pulling-on piece spurs first pull bar and second pull bar moves inwards, and first pull bar spurs first locking bar again and moves inward, and second end of first locking bar is extracted in fixing hole.In like manner, second pull bar spurs second locking bar again and moves inward, and second end of second locking bar is extracted in fixing hole, and is as shown in Figure 2.Rear Door does not have any constraint with the back doorframe like this, and the staff directly can extract door-plate out, has realized the unlatching of Rear Door.
