Description

A kind of rear door of switch cabinet novel trans blocking device
Technical field
The present invention relates to a kind of switch cubicle accessory, be specifically related to a kind of switch cubicle backlocking device.
Background technology
Switch cubicle is a kind of equipment for power transmission and distribution, and therefore, the requirement in terms of its safety is higher. Under normal circumstances, when switch cubicle power-off inspecting state, back door is typically to open, but simultaneously, The situation that back door is opened, switch cubicle also can carry out power transmission, and this is a drawback.
At present, what the back door backlocking device in power distribution cabinet equipment had is not also equipped with, and some is equipped with Easy blocking device, such as the locking of electromagnetic type back door, the locking of plain type back door, 90 ° of rotations Door latch apparatus etc. after reversible.Electromagnetic lock mode, belongs to on-mechanical linkage mode, unreliable, External environmental factor is bigger on its impact, and the high-intensity magnetic field of controller switching equipment easily disturbs electromagnetism Lock, can cause misoperation, in the case of the improper dead electricity of secondary power supply, chain is failure to actuate, can make Become operation or maintenance difficult, chain unreliable.Use door latch apparatus after Simple rotary formula, nothing It is chain that method realizes reversible, i.e. shutting back door, master switch is when shifting operating position onto, can realize Back door is lockable, but when opening back door, entering service mode, it is impossible to realize preventing from driving into and , there is huge potential safety hazard in the chain function of operation master switch, chain unreliable.90 ° of rotations Door latch apparatus after reversible, simple in construction, action is reversible, but there is cabinet deformation, main shaft The defects such as lock dog dislocation, cause the adverse consequencess such as chain inefficacy, mechanism's clamping stagnation, the company of ultimately causing Lock unsuccessfully, poor stability, jeopardizes human life.Therefore, unreasonable, irreversible, invalid Backdoor interlocking device, can reduce reliability and the safety of switchgear, threatens personal safety.
Summary of the invention
Goal of the invention: the invention aims to overcome deficiency of the prior art, it is provided that one Planting simple in construction, easy to operate, the rear door of switch cabinet that can be greatly improved switch cubicle safety is novel Backlocking device.
Technical scheme: in order to solve above-mentioned technical problem, after a kind of switch cubicle of the present invention Door novel trans blocking device, it includes the big axle fixed block being located on cabinet door, solid at described big axle Determine block and be provided with the earthed switch big axle of operation, the earthed switch behaviour on the right side of described big axle fixed block Make big axle and be provided with big axle auxiliary member, be provided with connecting pin, in institute in described big axle fixed block bottom Stating connecting pin and be provided with swinging mounting, described swinging mounting is fixed on cabinet by rotating fixed support Men Shang, is provided with catch bar in described swinging mounting bottom, and described catch bar passes through catch bar support It is fixed on cabinet door, that section of catch bar in described catch bar support is provided with spring stop piece, It is provided with back-moving spring between described spring stop piece and catch bar support rear portion, auxiliary at described big axle Assistant piece bottom is provided with link slot, and described connecting pin is connected, at described connecting pin with link slot coupling It is provided with connection post, is provided with lower connection post in described catch bar rear end, at described swinging mounting It is respectively arranged at two ends with connection post groove and lower connection post groove up and down, in described swinging mounting and rotation Fixed support junction is provided with and is rotationally connected post.
Described earthed switch operates big axle, connecting pin and catch bar and be arranged in parallel two-by-two.
Described big axle auxiliary member is fixing with the earthed switch big axle of operation to be connected.
The present invention is when back door is shut, and before catch bar is pushed to, drives swinging mounting, rotates and prop up Frame drives connecting pin toward retraction again, makes connecting pin be in disconnected position, and earthed switch operates big axle Just can carry out sub-switching operation.
The present invention is enforceable shuts ability power transmission by back door, replaces original not closing the door just may be used With the serious loophole of power transmission, solve and open back door and still can enhance " five with the problem of power transmission Anti-" function, it is greatly improved safety in technology, during the use of electricity cabinet, more enters The perfect safety work of one step, solves root problem, makes product use safer, reliably, More humane.
Beneficial effect: compared with prior art, its remarkable advantage is the present invention: the present invention is overall Simple in construction, easy to operate, use safety, easy to maintenance, by connecting pin and earthed switch Operate big axle operation associated so that only have a back door connection and shut ability power transmission, substantially increase switch cubicle Security performance, without potential safety hazard, this product using effect is good, meets actual operation requirements.
