Abstract

The utility model relates to an anti-misoperation interlocking device for switch boxes. The utility model is composed of a frame, a driving plate, a sliding plate, a tongue plate, a lock hook, a door ring, a lock hook ring, a box door, a marking plate, a handle, a locking spanner, a gripper block, etc., wherein, the lock hook, the door ring and the lock hook ring are arranged on the box door, the frame is arranged on a switch with a plastic casing fixed on a bottom box, and the driving plate, the sliding plate, the tongue plate, etc., are arranged on the frame. The mechanisms are cooperated with each other; so if the switch with a plastic casing is used when the power is switched on, the box door and the switch with a plastic casing form a mechanical interlock; thereby, the switch box can not be opened, and the box door can be opened only when the power is switched off. The utility model has the advantages of reasonable structure, high safety and reliable anti-misoperation function.

Description

Anti-misoperation interlocking device for switch box

The utility model relates to a kind of interlocker, particularly a kind of switch-box anti-misoperation interlocker.

Moulding in the existing enclosed knife switch case all do not have anti-misoperation between shell appliance switch and the chamber door, promptly can both open chamber door under charged situation, causes danger easily, jeopardizes personal safety.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of reliable anti-misoperation function that has is provided, and simple and reasonable switch-box anti-misoperation interlocker.

The purpose of this utility model can reach by following measure: the utility model comprises skeleton, latch hook, Men Quan, latch hook ring, marking panel, handle, locking wrench, it is characterized in that: also have the plate of dialling, slide plate, hyoplastron, fixture block, latch hook, Men Quan, latch hook ring to be installed on the chamber door, skeleton is installed in to be moulded on the shell switch, dialling plate, slide plate, hyoplastron is loaded on the skeleton, latch hook can be pushed down hyoplastron, hyoplastron can be placed restrictions on the rotation of dialling plate, dial plate and can drive skateboarding, fixture block is housed on the slide plate, and fixture block can drive moulds shell switching manipulation handle.

Fig. 1 is internal structure signal of the present utility model (facing) figure;

Fig. 2 is internal structure signal of the present utility model (side-looking) figure;

Fig. 3 is that A-A of the present utility model is to structural representation.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 3, the utility model by skeleton 1, dial plate 2, slide plate 3, hyoplastron 4, latch hook 5, door circle 6, latch hook ring 7, chamber door 8, marking panel 9, handle 10, locking wrench 11, mould shell switch 14, fixture block 13 etc. and form.Latch hook 5, door circle 6 and latch hook ring 7 are installed on the chamber door 8; Skeleton 1 is mounted on the executive component (for example moulding shell switch 14) on the under casing, dials plate 2, slide plate 3, hyoplastron 4 etc. and is loaded on the skeleton 1.

Behind key operated lock, set level the locking wrench 11 on the handle, the alignment pin that then protrudes in handle 10 handle that rebounds, for the rotary manipulation of handle ready.

Figure 1 shows that gate-dividing state, chamber door 8 is not closed, and hyoplastron 4 is by on the skeleton 1

Block in the shape hole, and placed restrictions on the rotation of group plate 2, makes that moulding shell switch 14 can not close a floodgate.(see figure 2) after door is closed, the position that is chamber door moves to II by I, adjust the position of latch hook 5, make latch hook 5 press to hyoplastron 4 right-hand, then dial plate 2 rotatable motions, move upward thereby drive slide plate 3, by being fixed on the fixture block 13 on the slide plate 3, drive is moulded shell switch 14 operating grips 12 and is moved upward, thereby finishes feed motion.

Behind the combined floodgate, hyoplastron 4 moves downward to the L shaped slotted eye of latch hook 5, thereby after closing a floodgate, chamber door 8 can not be opened.

During separating brake, dial plate 2, slide plate 3(fixture block 13) counter motion, hyoplastron 4 is jumped out in the L shaped slotted eye of latch hook, and this moment, chamber door 8 could be opened, and along with the unlatching of door, hyoplastron 4 is returned to again on hyoplastron 4 and the skeleton 1 to left movement

The position of shape hole interlocking.

In emergency circumstances, or need under powering-off state, repair and check, can adopt specific purpose tool to open chamber door.

The utility model has following advantage compared to existing technology:

1. when moulding the shell switch when use is closed a floodgate in energising, chamber door and switch form mechanical interlocking and can not open, and only have behind the switch circuit breaking separating brake, and chamber door can be opened, and has reliable anti-misoperation function. Simultaneously, the locking wrench on the operating grip can be locked, and is positioned to close a floodgate or open position, to prevent non-designated personnel's operation.

2. simple and reasonable, safe and reliable, can be widely used in by handle the move up and down appliance switch element operated and the procedure operation between the chamber door.

Claims
