Existing rotary separation switch is arranged on cabinet inside (as shown in Figure 1) and switch lever extends in cabinet 2 outside, cabinet door 1 is hinged with in cabinet 2 side, and the opposite side of cabinet 2 is connected with cabinet door 1 by padlock (not shown), when keeping in repair the equipment being arranged on cabinet 2 inside, first maintenance personal needs first to disconnect the circuit breaker being arranged on cabinet 2 outside according to the rules, then manually the switch lever extending in cabinet outside is promoted downwards, thus make the rotating shaft 3 be arranged on rotary separation switch rotate counterclockwise (seeing from right to left) drive plug-in strip 4 open, and then open the padlock together with being locked in cabinet 2 by cabinet door 1, finally open cabinet door 1 to keep in repair the equipment being arranged on cabinet 2 inside, but in actual mechanical process, maintenance personal is after disconnection is arranged on the circuit breaker of cabinet 2 outside, usually can forget disconnection rotary separation switch, then just padlock is opened, but find not disconnect rotary separation switch when opening cabinet door, in this operating process, very easily there is security incident, there is larger potential safety hazard, the serious personal safety compromising maintenance personal.
But for the deficiencies in the prior art, developer is necessary that a kind of reasonable in design, structure of development is simple, can effectively avoid maintenance personal that the situation of operate miss occurs, and security performance is high, " five prevent " interlock be connected between rotary separation switch and cabinet door that performance is strong.
Utility model content
For solving prior art Problems existing, the utility model object provide a kind of reasonable in design, structure simple, can effectively prevent maintenance personal from the situation of operate miss occurring, security performance is high, " five prevent " interlock be connected between rotary separation switch and cabinet door that performance is strong.
For solving above technical problem, the utility model realizes by the following technical solutions:
A kind of interlock be connected between rotary separation switch and cabinet door, comprise guiding trestle and linkage support, one end of described guiding trestle is fixedly mounted on cabinet door, gathering sill is offered at the other end of described guiding trestle, described linkage support is fixedly mounted in the rotating shaft of rotary separation switch, described linkage support is provided with the lead matched with gathering sill, when rotary separation switch is from open mode to closure state, described lead is under the drive of rotating shaft, proceed in the gathering sill of described guiding trestle, when rotary separation switch is from closure state to open mode, described lead is under the drive of rotating shaft, produce in the gathering sill of described guiding trestle.
In a preferred embodiment of the present utility model, described linkage support is welded in the rotating shaft of rotary separation switch.
In a preferred embodiment of the present utility model, the global shape of described guiding trestle is " L " shape.
In a preferred embodiment of the present utility model, the entirety of described gathering sill is formed as " U " shape.
Compared with prior art, the utility model comprises guiding trestle and linkage support, one end of guiding trestle is fixedly mounted on cabinet door, offer gathering sill at the other end of guiding trestle, linkage support is fixedly mounted in the rotating shaft of rotary separation switch, and linkage support is provided with the lead matched with gathering sill, when rotary separation switch is from open mode to closure state, lead, under the drive of rotating shaft, proceeds in the gathering sill of described guiding trestle, and cabinet door cannot be opened; When rotary separation switch is from closure state to open mode, lead, under the drive of rotating shaft, produces in the gathering sill of guiding trestle, and cabinet door can be opened, this interlock can effectively prevent maintenance personal from the situation of operate miss occurring, and security performance is high, " five prevent " performance is strong.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of prior art.
Fig. 2 is closing structure schematic diagram of the present utility model.
