The specific embodiment
For the ease of those skilled in the art's understanding, the invention will be further described below in conjunction with accompanying drawing.
As shown in accompanying drawing 1,2, the present invention has disclosed a kind of for the Qianmen of switchboard and the closedown structure of cable chamber door, comprise cabinet 1 and be located at Qianmen 2 and cable chamber door 3 on this cabinet 1, cabinet 1 upper inside wall is provided with cabinet fixed head 4, cabinet fixed head 4 edges, bottoms laterally offer cross through hole, edge vertically offers vertical through holes, cross through hole and vertical through holes are interconnected, and are provided with back door locking bar 5 on cable chamber door 3.Be provided with jam plate 6 and jam plate location-plate 7 in cabinet 1, this jam plate location-plate 7 is fixed on cable chamber door 3 inwalls, back door locking bar 5 is positioned at 7 of jam plate location-plates, jam plate 6 bottom activities interted jam plate location-plate 7, movable upper end and interted in the vertical through holes of cabinet fixed head 4, also were provided with the left end activity in cabinet 1 and passed cross through hole on cabinet fixed head 4 and the slide rod device on jam plate 6 tops.
Described slide rod device comprises slide bar locating piece 8 and the movable slide bar 9 that interted this slide bar locating piece 8, slide bar locating piece 8 is fixed in the interior upper wall of cabinet 1, be provided with fixture block 10 on slide bar 9, be set with the stage clip 11 that is positioned at 8 of fixture block 10 and slide bar locating pieces on slide bar 9, these stage clip 11 1 ends are fixed on slide bar locating piece 8, the other end is fixed on fixture block 10.Slide bar 9 left ends interted cross through hole and jam plate 6 on cabinet fixed head 4.Also be provided with the block 12 of the vertical through holes that is positioned at cabinet fixed head 4 above jam plate 6 upper ends.Slide bar locating piece 8 can arrange as required one, two or three, above-mentioned enumerating is not restriction to technical solution of the present invention.
In addition,, in order to guarantee the motion circuit of jam plate, be provided with the jam plate guide pad 13 that is positioned at above jam plate location-plate 7 on the inwall of cable chamber door 3, this guide pad 13 is passed in jam plate 6 activities.
As shown in Figure 3, all open at cable chamber door 3 and Qianmen 2, carries out interruption maintenance.Back door locking bar 5 is in the state of pulling open at this moment, jam plate 6 is along guide pad 13 and jam plate location-plate 7 decline certain distances, and block 12 blocks the cross through hole of offering on cabinet fixed head 4, makes slide bar 9 can not intert cabinet fixed head 4, Qianmen 2 in slide bar 9 right-hand member ejections simultaneously, and Qianmen 2 can't be closed.
as shown in Figure 2, close cable chamber door 3, Qianmen 2 stays open, then upwards pull back door locking bar 5, thereby drive jam plate 6 upward slidings, intert in the vertical through holes of cabinet fixed head 4 jam plate 6 upper ends, and then with block 12 upwards ejections, the cross through hole of cabinet fixed head 4 can not stopped by block 12, also offer the through hole that passes for slide bar 9 due to jam plate 6 tops, jam plate 6 upward slidings block no longer and move up to the jam plate 6 when cross through hole on cabinet fixed head 4 is connected of the through hole on it, this moment, slide bar 9 can intert cabinet fixed head 4 and jam plate 6 tops.
As shown in Figure 1, close Qianmen 2, slide bar 9 slides left under the promotion at Qianmen 2, because block 12 has upwards been pushed open by jam plate 6 and do not blocked cross through hole on cabinet fixed head 4, therefore, slide bar 9 left ends can intert cabinet fixed head 4 and jam plate 6, stage clip 11 on slide bar 9 is constantly compressed under the compressing at Qianmen, when Qianmen 2 is closed, slide bar 9 left ends had interted cabinet fixed head 4 and jam plate 6, stage clip 11 on slide bar 9 is in compressive state at this moment, and cable chamber door 3 and Qianmen 2 all are in closed condition, can power.
When needs are opened Qianmen and cable chamber door and are carried out interruption maintenance, first open Qianmen, slide bar is subject to the elastic force of stage clip, move right, make the slide bar left end withdraw from jam plate and cabinet fixed head, then operate the back door locking bar, jam plate is glided, and then make block again stop the cross through hole of cabinet fixed head, and make slide bar can not intert the cabinet fixed head, guarantee that Qianmen backed down and can't close by slide bar.
Above-described embodiment be the better embodiment of the present invention it, need to prove, under the prerequisite that does not break away from inventive concept of the present invention, any apparent replacement is all within protection scope of the present invention.
