Abstract
The invention discloses a kind of adjustable error-proof device, it is made up of portable plate, fixed plate, portable plate is provided with longitudinally adjust mouth and combination baffle, fixed plate is provided with mounting hole and combination regulation mouth, portable plate can translate or rotate within the specific limits relative to fixed plate so that the device lock-in range is extremely wide.The present invention simplifies practicality, can solve the problems, such as grounding knife of switch cabinet connector without suitable blocking device, thus reduce potential safety hazard, bigger guarantee is provided for the safety of staff.
Description
Technical field
The present invention relates to a kind of high-tension electricity work safety device, more particularly, to a kind of adjustable error-proof device.
Background technology
At present switch cubicle in a non-operative state when that earthing knife-switch still can be operated arbitrarily be present, be likely in this case
Faulty operation can be caused, causes electric shock and other safety accidents.To avoid this kind of accident from occurring, it is necessary to take some modes to prevent.
Common method is to hang warning sign or eye-catching warning red cloth, but this method can not objectively debug operation possibility
Property；Error-proof device can additionally be increased on valve, most error-proof devices are all only applicable to small part model switch on the market
Cabinet, including so-called universal error-proof device also only apply to the switch cubicle of a part, and many switch cubicles are difficult to find that matching type
Number, the error-proof device of size.
The content of the invention
The present invention is in order to overcome prior art lower switch cabinet error-proof device can not adapt to all switch cubicles, so that part
Model switch cubicle can not carry out the problem of safety interlocking produces potential safety hazard, there is provided a kind of adjustable error-proof device, to meet not
The switch cubicle of demand with to(for) safety interlocking.
To achieve these goals, the present invention uses following technical scheme：A kind of adjustable error-proof device, especially can be with
In a wide range of interior adjustment grounding knife of switch cabinet connector closure and the device of open state, the device includes portable plate and fixed plate,
Both parts can be movable relative to each other, closure thus, it is possible to the grounding knife of switch cabinet connector in the range of control section and opens
Put, wherein portable plate has longitudinally adjust mouth and combination baffle, and fixed plate has combination regulation mouth.Pass through longitudinally adjust mouth and group
Regulation mouth is closed, portable plate can translate or rotate on portable plate and the faying surface of fixed plate relative to fixed plate, thus movable
Combination baffle on plate being capable of flexible modulation ' locked ' zone within the specific limits.
Preferably, fixed plate is L-type, mounting hole is arranged in the FX of L-shaped fixed plate.L-shaped fixed plate can pacify
At inside switch cabinet neck.
Preferably, combination baffle point a baffle plate and two baffle plates, a baffle plate, two baffle plates and portable plate are orthogonal.It is multiple
Baffle plate expands its lock-in range, and portable plate may also function as certain locking effect in itself, orthogonal to can reach with multi-angle
Locking acts on, and makes it can be with flexible modulation mounting plate.
Preferably, longitudinally adjust mouth and combination regulation mouth are Long Circle.The longitudinally adjust mouth of Long Circle and combination are adjusted
Save mouth and be beneficial to the fixed and movable of bolt and nut, improved to greatest extent in the case where not influenceing portable plate and fixed plate activity
The connective stability of two plates.
Preferably, combination regulation mouth at least has two.Two and more than two activity adjustment mouths provide activity
Plate is relative to the rotation regulating power of fixed plate, and two and two connections that further increase between two plates of combination regulation mouths are steady
It is qualitative.
Therefore, the present invention has the advantages that：Portable plate can by longitudinally adjust mouth and combination regulation mouth relative to
Fixed plate is adjusted angle, position, further according to required control lock-in range inside a larger scope；Mounting hole is in L
The FX of type fixed plate can be more convenient neatly mounting plate, have stronger universality in the selection of mount point；
Combination baffle is orthogonal, and lockable angle is more, has in a disguised form been further added by the lock-in range of the adjustable error-proof device.

Embodiment
The present invention will be further described with embodiment below in conjunction with the accompanying drawings.
In embodiment as shown in Figure 1, the present invention is a kind of adjustable error-proof device, especially can be in a wide range of interior tune
The device of the whole closure of grounding knife of switch cabinet connector 2 and open state, the device include portable plate 5 and fixed plate 3, both parts
Can be movable relative to each other, closure and opening thus, it is possible to the grounding knife of switch cabinet connector in the range of control section, wherein living
Dynamic plate has longitudinally adjust mouth 8 and combination baffle 7, and fixed plate has combination regulation mouth 10.The device is used for switch cubicle 1, passes through
Longitudinally adjust mouth and combination regulation mouth, portable plate can be translated relative to fixed plate on portable plate and the faying surface of fixed plate or
Rotate, thus the baffle plate on portable plate being capable of flexible modulation ' locked ' zone within the specific limits.Fixed plate is L-type, and mounting hole 6 is set
Put in the FX 9 of L-shaped fixed plate.Fixed plate is arranged inside switch cabinet neck by nut, and mounting means is
Be hinged, fixed plate can be rotated as origin using mounting hole but do not loosened.Combination baffle point a baffle plate and two baffle plates, a baffle plate, two
Baffle plate is orthogonal with portable plate.Multiple baffle plates expand its lock-in range, and portable plate may also function as certain locking and makees in itself
With, it is orthogonal to can reach the effect of locking with multi-angle, there can be more peaces in the case of without internal neck or installation difficulty
The selection of dress, make it can be with flexible modulation mounting plate.Longitudinally adjust mouth and combination regulation mouth are Long Circle.Long Circle
Longitudinally adjust mouth and combination regulation mouth are beneficial to the fixed and movable of bolt and nut, are not influenceing the feelings of portable plate and fixed plate activity
The connective stability of two plates is improved under condition to greatest extent., two combination regulation mouths provide portable plate relative to fixed plate
Regulating power is rotated, and two and two activity adjustment mouths further increase the connective stability between two plates.
In embodiment as shown in Figure 2 and Figure 3, the error-proof device is installed on switch cubicle, and combination baffle blocks switch cubicle
Earthing knife-switch connector, it is not connected and prevent potential safety hazard.When needing the connection work of grounding knife of switch cabinet connector, it is only necessary to open
Connection portable plate and the lock of lock hanging 4 can put down single unit system, and grounding knife of switch cabinet connector is unobstructed again, in can connect
State.
