Description
Technical field
It is especially a kind of protection screen the utility model relates to apply the protection screen cabinet in places such as substation, power plants
Cabinet link lock.
Background technique
With the intelligentized development of power industry, apply the occasions such as substation, power plant protection screen cabinet also increasingly
It is more, mainly for the protection of the safe operation of important equipment, and once shield the failure of the protective device in cabinet, it is necessary in time to it
It is handled, otherwise will cause the damage of important electric power facility.As the link lock being mounted on protection screen cabinet, usually in addition to
The cabinet door of protection screen cabinet is carried out outside effectively locking, when needing that device in cabinet is overhauled or repaired, it is necessary to guarantee
Cabinet door it is normally-open.
The connecting rod lockset of existing cabinet door is fixedly connected by one piece of screw mostly between connection sheet and locking bar, for a long time
After use, screw is very easy to fall off, when unlock when, locking bar will be unable to the movement with connection sheet and move, cause cabinet door without
Method is opened, and is caused protective device to be difficult to be overhauled or repaired in time, has been seriously affected the safe operation of power equipment, therefore,
Need to develop a kind of new link lock.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, installation is easy to operate, and in connection spiral shell
Nail can still drive locking bar mobile in the case where falling off, to guarantee the normally-open protection screen cabinet link lock of cabinet door.
The technical solution of the utility model is to provide a kind of protection screen cabinet link lock having following structure, packet
Lock body, connection sheet and locking bar are included, the upper and lower part of the lock body is mounted on a connection sheet, and the other end of each connection sheet is equal
It is connected with a locking bar, the end of the locking bar is equipped with the plate to fit with connection sheet, and the plate and connection sheet overlap
Position is equipped with the bending section to side bending, bending section through the through-hole penetrated for screw, the end of the connection sheet is offered
Both sides of the head wall on be equipped with barb, the middle part of bending section offers open slot along length direction, opens on the plate
Equipped with the connecting hole being inserted into for bending section, after in bending section insertion connecting hole, the plane of two barb rear ends is acted in elastic force
The lower edge that will ride upon connecting hole automatically, to prevent bending section from voluntarily deviating from out of connecting hole.
A kind of protection screen cabinet link lock described in the utility model, wherein the lock body is equipped with the vertical chute, vertically
It can slide up and down in sliding slot and slide plate is installed, be successively arranged red grooves and green grooves from top to bottom on the surface of slide plate,
Tension spring is equipped between one end and lock body of the slide plate, the other end is connected with pull rod, and the other end of the pull rod is equipped with for screw
The ring segment of insertion offers watch window on the lock body, after covering ring segment on screw, green grooves and observation window
Mouth face, and after ring segment falls off from screw, red grooves and watch window face.
After using the above structure, compared with prior art, a kind of protection screen cabinet of the utility model link lock has following
Advantage：Locking bar and connection sheet are attached outside by the utility model except through screw, and also bending section is inserted into connecting hole, and
The plane of rear end is set to ride upon connecting hole edge by the elastic force of barb, the structure of this dual connection realizes locking bar and company
Contact pin is reliably connected, and therefore, after toner screw, locking bar and connection sheet can still link together, and then ensure cabinet door
It is normally-open, solve the prior art after toner screw, locking bar can not realize unlocking with the movement of connection sheet, cause
The technical issues of cabinet door can not be opened, the maintenance of delay protective device or maintenance.In addition, the utility model structure is simple, installation behaviour
Facilitate.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view of protection screen cabinet link lock of the utility model；
Fig. 2 is a kind of top half broken section enlarged structure schematic diagram of protection screen cabinet link lock of the utility model；
Fig. 3 is vertical view enlarged structure schematic diagram when bending section is inserted into connecting hole in Fig. 1.
Specific embodiment
A kind of protection screen cabinet of the utility model is made with link lock with reference to the accompanying drawings and detailed description further detailed
It describes in detail bright：
As shown in Figures 1 to 3, in this embodiment, a kind of protection screen cabinet of the utility model link lock includes lock
Body 17, connection sheet 13 and locking bar 10, the upper and lower part of lock body 17 are mounted on a connection sheet 13 (specific mounting structure and existing
Have technology identical), the other end of each connection sheet 13 is respectively connected with a locking bar 10.The end of locking bar 10 is equipped with and 13 phase of connection sheet
The plate 101 of fitting, plate 101 and connection sheet 13 overlap position through offering the through-hole penetrated for screw 12；Connection sheet
13 end is equipped with the bending section 131 to side bending, is equipped with barb 132, bending section on the both sides of the head wall of bending section 131
131 middle part offers open slot 133 along length direction；The connecting hole being inserted into for bending section 131 is offered on plate 101
11, after bending section 131 is inserted into connecting hole 11, the plane of two 132 rear ends of barb will ride upon automatically under the effect of elasticity
The edge of connecting hole 11, to prevent bending section 131 from voluntarily deviating from out of connecting hole 11.
Lock body 17 is equipped with the vertical chute 20, can slide up and down in the vertical chute 20 and be equipped with slide plate 18, slide plate 18
