Abstract
The utility model relates to an interlock mechanism for an electric switch cabinet, in particular to a rear blanking plate interlock for a switch cabinet, which comprises a rotating shaft which passes through the horizontal midpoint of a rear blanking plate, wherein one end, which is positioned on outer lateral surface of the rear blanking plate, of the rotating shaft is connected with a rotary handle, and one end, which is positioned on inner lateral surface of the rear blanking plate, of the rotating shaft is fixedly connected to the middle of a rotary pulling sheet; the two corresponding ends of the rotary pulling sheet are coupled with the inner end of a movable lock rod respectively; and the outer end of the movable lock rod passes through guide holes of lock rod limit pieces which are fixedly arranged on left and right sides of the inner lateral surface of the rear blanking plate. By the rear blanking plate interlock, the technical problem that an electromagnetic lock structure used in the conventional switch cabinet of which the rear blanking plate can be opened is high in cost and exerts electromagnetic interference with other electric elements in the cabinet easily during running is solved, and when the rear blanking plate is opened, the rear blanking plate interlock does not occupy the large space and is easy to operate.
Description
Technical field
The utility model relates to the interlocking device of cabinet, shrouding interlocking behind particularly a kind of switch cubicle.
Background technology
As everyone knows, all have back shrouding on the cabinet of cabinet, generally speaking, back shrouding all is the fixing fixed connection structure that can not open.But also the back shrouding of some cabinet (as: KYN28 switch cubicle) is required to be set to openable.Generally, the structure that the mode of main employing electromagnetic lock realizes opening the back shrouding, but this electromagnetic lock structure but has following problem: the cost of (1) electromagnetic lock is than higher, and its electromagnetic structure produces electromagnetic interference during easily to other operation of electric element in the cabinet; (2) can only electromagnetic lock be set in a side of back shrouding usually, opposite side then is provided with the articulated structure between back shrouding and the cabinet, and during use, back shrouding just need take certain space when opening, this just implements relatively difficulty for the more limited power distribution room in space.
The utility model content
Shrouding was interlocked after the purpose of this utility model was to provide a kind of switch cubicle, mainly solve the openable switch cubicle of existing back shrouding and mainly adopt electromagnetic lock structure, not only cost is higher, and electromagnetic structure produces the technical problem of electromagnetic interference during easily to other operation of electric element in the cabinet, this product can not take bigger space when the back shrouding is opened, and operates fairly simple.
For achieving the above object, the utility model is to realize like this.
Shrouding interlocking behind a kind of switch cubicle, it is characterized in that: it comprises a rotating shaft that is located in shrouding horizontal mid-point place, back, this rotating shaft is positioned at back shrouding lateral surface one end and connects rotating handles, and this rotating shaft is positioned at the centre that back shrouding medial surface one end is fixedly connected on a rotation pulling-on piece; Be coupling respectively the inner of mobile locking bar of the opposite ends of this rotation pulling-on piece; The outer end of this mobile locking bar is located in respectively in the guide hole of the locking bar locating part that is fixedly installed on the shrouding medial surface left and right sides, back.
Shrouding interlocking behind the described switch cubicle is characterized in that: described mobile locking bar all is divided into two joints by the part that is coupling, and a joint that is located in the guide hole of locking bar locating part is shorter than a joint that connects the rotation pulling-on piece.
The utility model is created compared with prior art, and have following advantage and good effect: the utility model adopts pure mechanical structure, can not produce electric equipment in the cabinet during use and disturb.The utility model is simple in structure, and is easy to operate, do not take the operating space.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a user mode schematic diagram of the present utility model.
Embodiment:
See also Fig. 1, it is a shrouding interlocking behind a kind of switch cubicle of the utility model.As shown in the figure: it comprises a rotating shaft 2 that is located in shrouding 1 horizontal mid-point place, back, and this rotating shaft 2 is positioned at back shrouding 1 lateral surface one end and connects rotating handles, and this rotating shaft 2 is positioned at the centre that back shrouding 1 medial surface one end is fixedly connected on a rotation pulling-on piece 3; Be coupling respectively the inner of mobile locking bar 41,42 of the opposite ends of this rotation pulling-on piece 3; The outer end of this mobile locking bar 41,42 is located in respectively in the guide hole of the locking bar locating part 51,52 that is fixedly installed on the shrouding 1 medial surface left and right sides, back.
When the utility model uses as shown in Figure 2, the user is enclosed in the switch cubicle trailing flank with the back shrouding earlier, and afterwards passing through the rotation rotating handles outside the shrouding, rotating handles drives mobile locking bar 41,42 and carries out expanding-contracting action, mobile locking bar 41,42 can be further under the guide effect of the guide hole of locking bar locating part 51,52 behind switch cubicle the fixing hole of both sides or holddown groove direction insert to realize that the back shrouding fixes; Otherwise, then can open the back shrouding.
As a kind of preferred structure, described mobile locking bar 41,42 all is divided into two joints by the part that is coupling, and a joint that is located in the guide hole of locking bar locating part 51,52 is shorter than a joint that connects rotation pulling-on piece 3.It is more laborsaving so to operate.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model, and promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
