Abstract
The utility model provides a switch cabinet double-door multi-point locking structure which comprises a switch cabinet outer door frame, a left door body, a right door body, a door hinge, door lock mechanisms and a door middle frame. The switch cabinet double-door multi-point locking structure is characterized in that the door middle frame is detachably connected on the switch cabinet outer door frame, one side portions of the left door body and the right door body are symmetrically fixed on the left side frame and the right side frame of the outer door frame through the door hinge, a plurality of door lock mechanisms are arranged on the other side portions of the left door body and the right door body, and lock points which correspond to the plurality of door lock mechanisms are arranged on the door middle frame. The switch cabinet double-door multi-point locking structure is simple, the space in a switch cabinet is not occupied, interference on equipment in the switch cabinet cannot happen, and the switch cabinet double-door multi-point locking structure is especially suitable for being used in the rectifying project of original switch cabinets with the design which can not meet the anti-explosion requirements of electric power companies in various regions.
Description
Technical field
The utility model relates to a kind of switchboard clamshell doors multi-point locking structure.
Background technology
In recent years, along with expanding economy, China Power industry is keeping the situation of high speed development, is faced with unprecedented development as one of the guarantee of electric power industry development switchboard manufacturing industry.Simultaneously because the development of China Power, care to humanity also more and more obtains paying attention to, performance (particularly explosion-proof performance) to switchboard proposes more and more higher requirement, the special requirement cabinet door will be realized Multiple locking point locking, early stage a lot of switchboards are not owing to conform to requirement of explosion proof and be faced with and be eliminated, and this will cause very large waste to resource.Therefore the old rectification that does not conform to the target switchboard is made its Utilities Electric Co.s at different levels agenda of having put on up to standard.
Adopt at present its locking mechanism of door structure switchboard mainly to adopt at door and adopt upper and lower cotter joint lock form, there is following shortcoming in this structure:
1, the lock point is few, only has 2 lockings; 2, intensity is low, and when in the switchboard during arcing, thereby the high temperature and high pressure gas that arcing produces easily will lock and a little rush curved cabinet door is washed open and jeopardize operator safety on every side.
Summary of the invention
The utility model purpose is to overcome above-mentioned shortcoming, a kind of switchboard clamshell doors locking mechanism that provides, and this structure has former cabinet change amount few, other secondary device in the switchboard is not caused interference thereby do not take the interior space of former switchboard.
Switchboard clamshell doors multi-point locking structure of the present utility model, comprise switchboard exterior door frame, left-hand door body, right door body, door hinge, door lock mechanism, door center, described door center adopts detachable being connected on the switchboard exterior door frame, described left-hand door body and right Men Tiyi sidepiece are symmetrically fixed on the right and left frame of exterior door frame by door hinge, the other side of described left-hand door body and right door body is provided with a plurality of door lock mechanisms, and described door center is provided with a plurality of lock corresponding with door lock mechanism points.
Above-mentioned door lock mechanism comprises slide bar, and described slide bar cooperates with the lock point, in order to locking left-hand door body, right door body.
Two frame convexes of above-mentioned door center rise, and described lock point is arranged on two frames of a center.
The utility model advantage is:
1, in the clamshell doors of switchboard, realized the Multiple locking point locking function;
2, minimum to changing workload in the former switchboard.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is door center right view of the present utility model.
Fig. 3 is door center elevation of the present utility model.
Fig. 4 is door center top view of the present utility model.
Fig. 5 is that the slide bar of door lock mechanism of the present utility model is at the locking of door center and the releasing process schematic diagram that opens the door.
Among the figure: 1-door hinge, 2-left-hand door body, 3-door lock mechanism, 4-slide bar 5-right door body 6-switchboard exterior door frame 7-door center.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing 1 ~ 2, switchboard clamshell doors multi-point locking structure of the present utility model, comprise switchboard exterior door frame 6, left-hand door body 2, right door body 5, door hinge 1, door lock mechanism 3, door center 7, described door center 7 adopts detachable being connected on the switchboard exterior door frame 6, described left-hand door body 2 and right door body 5 one sidepieces are symmetrically fixed on the right and left frame of switch exterior door frame 6 by door hinge 1, the other side of described left-hand door body 2 and right door body 5 is provided with a plurality of door lock mechanisms 3, and described door center 7 is provided with a plurality of lock corresponding with door lock mechanism points.
Above-mentioned door lock mechanism comprises slide bar 4, and described slide bar 4 cooperates with the lock point, in order to locking left-hand door body 2, right door body 5.
Two frame convexes of above-mentioned door center 7 rise, and described lock point is arranged on two frames of a center 7.
This equipment specific implementation process is as follows: left-hand door body 2 and right door body 5 are fixed on the switchboard exterior door frame 6 by door hinge 1 and the left and right door body is rotated around door hinge 1, door center 7 is bolted on the switchboard exterior door frame 6, be installed with door lock mechanism 3 on left-hand door body 2 and the right door body 5, with can up and down slide bar 4, the slide bar 4 when the left and right door body is closed on the door lock mechanism 3 snaps in 3 slide bars 4 of (such as Fig. 3) rotary door latch mechanism move down in the lock point of a center 7 the lock point on the door center and has just hooked slide bar 4 left and right door can not be opened on the door lock mechanism 3.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
