Abstract
The utility model discloses a switch cabinet with a back-off interlock device and belongs to the technical field of universal mechanical equipment. The switch cabinet comprises a cabinet body which is provided with a lower door plate, wherein an insert pin, which can be inserted into the lower door plate, is arranged in the cabinet body, a baffle plate, which can move and prevent the insert pin from being inserted into the lower door plate, is arranged in the cabinet body above a push plate, the top end of the lower door plate is provided with the push plate which can be inserted inside the cabinet body and push the baffle plate, and the baffle plate is provided with a spring member which is used for resetting the baffle plate. When the lower door plate is closed, the push plate is inserted into the cabinet body, the baffle plate is pushed to the backside of the cabinet body, and the insert pin is enabled to be inserted into the lower door plate, so that the lower door plate cannot be opened during equipment operation, the misoperation is prevented, and the use is safer; and the lower door plate can be opened after the insert pin leaves the lower door plate, the push plate is divorced from the cabinet body, the baffle plate moves forwards under the action of a resetting force of the spring member so as to baffle the insert pin, and the insert pin cannot move downwards, so that after the lower door plate is opened, an operator cannot operate the switch cabinet, and dangerous accidents are prevented.
Description
Technical field
The utility model relates to a kind of switchboard with rollback interlock, belongs to the general machinery equipment technical field.
Background technology
Switchboard is applicable to the electrical distribution system of the power consumers such as transformer station, power plant, industrial enterprise, as power, throw light on and be transported to electric equipment electric energy conversion, distribute and control, its inside is equipped with high voltage cable, so switchboard is in charged, can not open arbitrarily, otherwise just be easy to occur security incident.Existing equipment mostly is provided with interlock, prevents maloperation, but complex structure breaks down easily.
Summary of the invention
For addressing the above problem, it is a kind of simple in structure, easy to operate that the utility model provides, the safe and reliable switchboard with rollback interlock.
The utility model is that the technical scheme that its problem of solution adopts is:
Switchboard with rollback interlock, comprise the cabinet that is provided with lower door-plate, be provided with the latch that can insert lower door-plate in the described cabinet, the top that is positioned at top board in the cabinet is provided with removable and stops that latch inserts the baffle plate of lower door-plate, the top of lower door-plate is provided with the top board that can insert cabinet inside and promote baffle plate, and described baffle plate is provided with the spring part that baffle plate is resetted.
When door-plate cuts out instantly, top board on the lower door-plate inserts in the cabinet, and push baffle plate to the cabinet rear, baffle plate is drawn back, latch can freely be fallen, and insert in the lower door-plate, the upper end of latch is connected with operation panel, operation panel be used for opening or the closing switch cabinet panel on handle hole, after latch moved down, the operator just can insert action bars in the cabinet and operate, after the more important thing is that latch inserts lower door-plate, lower door-plate can't be opened when equipment moves, prevent maloperation, use safer.Only have when latch up mobile, leave lower door-plate after, lower door-plate just can be opened, after lower door-plate is opened, top board breaks away from cabinet, and baffle plate is mobile forward under the restoring force effect of spring part, blocks latch, it can't be moved down, after latch moved up, operation panel blocked handle hole, made action bars can't insert in the cabinet, thereby so that the operator can't be after lower door-plate be opened the console switch cabinet, prevent the generation of peril.
Preferably, the cross section of described baffle plate is T-shaped, and the one side arm is provided with the installing hole for mounting spring part one end, also is provided with fluting on this side arm, and spring part is free-extension in this fluting.
The beneficial effects of the utility model are: when door-plate cuts out instantly, top board on the lower door-plate inserts in the cabinet, and push baffle plate to the cabinet rear, baffle plate is drawn back, latch can freely be fallen, and insert in the lower door-plate, thereby lower door-plate can't be opened when equipment moves, prevent maloperation, use safer; Only have the latch of working as up mobile, after leaving lower door-plate, lower door-plate just can be opened, and after lower door-plate was opened, top board broke away from cabinet, baffle plate is mobile forward under the restoring force effect of spring part, block latch, it can't be moved down, thereby so that after door-plate is opened down, the operator can't the console switch cabinet, prevents the generation of peril.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is the enlarged drawing of A section among Fig. 1;
Fig. 3 is the structural representation of lower door-plate when opening;
Fig. 4 is the structural representation of the utility model baffle plate.
The specific embodiment
A kind of switchboard with rollback interlock shown in accompanying drawing 1, accompanying drawing 2, comprise the cabinet 2 that is provided with lower door-plate 1, be provided with the latch 3 that can insert in the lower door-plate 1 in the described cabinet 2, be provided with removable in the cabinet 2 and stop that latch 3 inserts the baffle plate 4 of lower door-plates 1, the top of lower door-plate 1 is provided with the top board 5 that can insert cabinet 2 inside and promote baffle plate 4, and described baffle plate 4 is provided with the spring part 6 that baffle plate 4 is resetted.
When door-plate cuts out instantly, top board 5 on the lower door-plate 1 inserts in the cabinet 2, and push baffle plate 4 to cabinet 2 rears, baffle plate 4 is drawn back, and latch 3 can freely be fallen, and inserts in the lower door-plate 1, the upper end of latch 3 is connected with operation panel, operation panel be used for opening or the closing switch cabinet panel on handle hole, after latch 3 moved down, the operator just can insert action bars in the cabinet 2 and operate.After the more important thing is that latch 3 inserts lower door-plate 1, lower door-plate 1 can't be opened when equipment moves, prevent maloperation, use safer.
As shown in Figure 3, only have when latch 3 up mobile, leave lower door-plate 1 after, lower door-plate 1 just can be opened, after lower door-plate 1 was opened, top board 5 broke away from cabinets 2, baffle plate 4 is mobile forward under the restoring force effect of spring part 6, blocks latch 3, and it can't be moved down.After latch 3 moved up, operation panel blocked handle hole, and action bars can't be inserted in the cabinet 2, thereby so that the operator can't be after lower door-plate 1 be opened the console switch cabinet, prevent the generation of peril.
Again as shown in Figure 4, the cross section of described baffle plate 4 is T-shaped, and the one side arm is provided with the installing hole 41 for mounting spring part 6 one ends, and the other end of spring part 6 is installed on the support of cabinet 2.Also be provided with fluting 42 on the above-mentioned side arm, spring part 6 is at these 42 interior free-extensions of slotting.Baffle plate 4 can pass through the compression mod moulding, but preferably by the sheet metal component punch forming, in moulding fluting 42, vertical section 43 of this T-shaped baffle plate 4 also forms out, and not only cost of production is low, and moulding is simple, and production efficiency is high.
