Description

A kind of PLC control cabinet

Technical field

The utility model relates to PLC to control apparatus field, and in particular to a kind of PLC control cabinet.

Background technique

PLC control cabinet is equipment very widely used in electric control system, automation control, electricity especially in industry In the industries such as power control and metallurgy.Because having the defencive functions such as overload, open circuit and open-phase protection, PLC control becomes PLC control cabinet The core of modern industry control.

Existing PLC control cabinet includes cabinet and the case lid that is hinged on cabinet, welds more support bars in cabinet, is supporting Mounting hole is opened up on item, separated time slot is opened up below support bar, the related component of PLC control cabinet is on support bar, Ge Geyuan The reserved conducting wire of device is placed in separated time slot, so that reserved arrangement of conductors is more orderly, heat release hole, Ge Geyuan are opened up on cabinet The heat that device generates when working is outside heat release hole export cabinet.

But when carrying out inspection maintenance to above-mentioned PLC control cabinet, only opening case lid can just see each of bottom in cabinet A component, meanwhile, cabinet internal cause is mounted with a variety of components, and has laid more conducting wire, and the intracorporal light of case is weaker, patrols It needs to be illuminated by other light sources when looking into maintenance, when attended operation is inconvenient.

Utility model content

The utility model is intended to provide a kind of PLC control cabinet, need to secretly be borrowed very much with solving the light when safeguarding PLC control cabinet The problem of helping other light sources to illuminate.

PLC control cabinet in this programme, the cabinet including offering mounting groove are installed on the inner wall of the mounting groove more Root installs the support bar of electric elements, offers mounting hole on the support bar, offers on the slot bottom below the support bar Separated time slot is hinged with case lid on the cabinet left side wall, offers peep hole on the case lid, in the inner bottom wall of the peep hole It is hinged with closure door, the closure door is equipped with handle towards the side outside cabinet, is installed with and prolongs on the bottom end on the right side of the closure door Boom；

Switch cylinder is installed on the right side wall of the mounting groove, the switch cylinder is closed for extension rod in closure door and case lid When be inserted into, fixed there are two conductive metal head on the inner wall of the switch cylinder, the position of the conductive metal head is mutually contradictory, institute It states and is equipped with conductive sheet between conductive metal head, pressure spring, the extension boom end are equipped between the conductive sheet and the inner bottom surface for switching cylinder It is installed with when closure door and case lid are closed to the insulated column for opening conductive sheet, has been electrically connected conducting wire on the conductive metal head, The mounting groove roof is equipped with headlamp and power supply, the headlamp, power supply, conducting wire and the series connection of conductive metal head.

The working principle and beneficial effect of this programme is: in installation casing, various components are mounted on support bar, respectively The circuit connection conducting wire of kind component is placed in separated time slot, closes case lid after the completion of installation and wiring, avoids different member devices The conducting wire of part is mutually obscured, and extends in the insulated column insertion switch cylinder of boom end, insulated column, which supports, opens conductive sheet, and pressure spring generates compression Elastic deformation, headlamp disconnect power supply, headlamp are avoided to light waste electric power resource always.

When whether staff needs the internal various components of inspection and route to work normally, it only need to haul handle and pull open Closure door can pass through the partial picture that peep hole sees box house, and handle facilitates staff to pull out closure door；Work as staff When needing the intracorporal component of Maintenance and Repair case and route, staff need to only pull open case lid i.e. and the entirety of box house can be seen Situation；While when pulling open closure door or case lid, because closure door is located on case lid, closure door or case lid drive extension rod mobile, extend The insulated column of boom end is routed up switch cylinder, and conductive sheet is arrived to conductive metal during pressure spring restores elasticity of compression deformation Between head, conductive sheet is connected to two conductive metal heads, allows headlamp connection power supply to light, headlamp carries out after being lit in cabinet Illumination, staff illuminate without other light sources, and operation when safeguarding cabinet is simpler, inspection, maintenance and maintenance When it is more convenient.

Compared with prior art, staff is pulling open closure door or case lid simultaneously, and headlamp is lit, and staff is not necessarily to It is illuminated by other light sources, attended operation is simpler, and staff is facilitated to use.

Further, the conductive metal head is embedded on the inner wall of switch cylinder, is installed at the both ends of the conductive sheet Spherical end, the conductive sheet are against the center of conductive metal head when pressure spring is under free state.

When opening closure door or case lid, pressure spring is not affected by the pressure of extension rod and is in free state, the end of conductive sheet Contact conductive metal head powers on headlamp, and conductive sheet is located at conductive metal centriciput, enables pressure spring by conductive sheet standard It is really pushed on conductive metal head and lights headlamp, guarantee that headlamp can be illuminated when pulling open closure door or case lid, spherical shape is disconnected Head does not have corner angle, and conductive sheet is avoided to be stuck in moving process.

Further, jack is offered on the roof of the peep hole, and L-shaped fixation hole is offered in the closure door, it is described Handle is threaded in the vertical section of fixation hole, and sphenocephaly is installed on the end that the handle is located in mounting hole, described It is equipped with the inserting column that can be inserted into jack in the horizontal segment of fixation hole, is installed with elastic string between the inserting column and the side wall of vertical section.

When closing closure door, handle is turned, the sphenocephaly of handle is screwed into the horizontal segment of fixation hole, sphenocephaly will be inserted Column supports in horizontal segment insertion jack, and elastic string generates tensile elasticity deformation, and closure door is fixed in peep hole, avoids peep hole Rainwater is flowed into when rainy；When needing to open closure door, vertical section a part that handle makes sphenocephaly exit fixation hole is screwed, he Elastic string restores elastic deformation and inserting column is retracted horizontal segment, closure door is opened, using simple.

Further, iron block is welded at the right side of the case lid, the cabinet is installed with forever in the right side wall of iron block Magnet.

The closing of closure door is attracted each other progress by iron block and permanent magnet, meanwhile, iron block maintains easily personnel and makees iron block It is easy to use for knob.

Further, gas vent is offered on the right side wall of the cabinet, and the row of electric connection of power supply is equipped in the gas vent Fan, is electrically connected with the conductive terminal that can be connected by conductive sheet between the exhaust fan and power supply, the conductive terminal is located at switch On side wall in cylinder between bottom and conductive metal head.

When closure door and case lid close when, extend boom end insulating segment insertion switch cylinder in by conductive sheet to switch cylinder in bottom To moving, conductive sheet convinces electric metal head by patient analysis by arrival & departure, between conductive sheet is arrived to conductive terminal, exhaust fan connection power supply is made to carry out work Make, exhaust fan closure door and case lid close when to radiating in cabinet, avoid box interior temperature excessively high, when open closure door or When case lid, exhaust fan stop working avoids accidentally touching exhaust fan after opening case lid or closure door and hurting staff.
