Description
Technical field
The utility model relates to indoor steel-clad switchbox, particularly a kind of Novel switch cabinet back door locking device.
Background technology
Indoor armored metal enclosed switch equipment is the widely used controller switching equipment of electric power system, for three-phase 50Hz in electric power system, can for the control and protection of the electric power system such as industrial and mining enterprises and transformer station, current existing switch cubicle, it is safeguarded, when checking and keep in repair, need first to close earthed switch, then just back door can be opened, the potential safety hazard caused due to the mistake of operating sequence can be prevented like this, but existing interlock, switch cabinet grounding switch cannot be realized upon installation, need back door to shut and just can carry out power transmission operation, therefore there is certain potential safety hazard.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, thus provides a kind of Novel switch cabinet back door locking device, and security performance is high.
The technical scheme that the utility model adopts is such: Novel switch cabinet back door locking device, comprise the blocking lock mechanism be arranged in switch cabinet body and the plate be arranged on back door, described switch cabinet body offers the perforation of passing for described plate, described blocking lock mechanism comprises U-shaped mounting bracket, to slide mutually the blocking pin arranged along horizontal direction and described mounting bracket, to rotate the earthed switch rotation axis arranged with described mounting bracket, described blocking pin is fixedly connected with stopper, described earthed switch rotation axis is fixedly installed stop connecting lever, described stopper and described stop connecting lever are all between described mounting bracket, described plate offers opening up locked groove, described locked groove matches with described stop connecting lever, return springs is provided with between described stopper and described mounting bracket.
Further improvement: described stopper have match with described stop connecting lever dodge inclined-plane.
Further improvement a: end of described blocking pin is fixedly installed limiting section, its other end is sticking department, and described return springs is between described limiting section and described stopper.
By adopting preceding solution, the beneficial effects of the utility model are: when back door is opened, the elastic force of return springs makes blocking pin stretch out switch cubicle, now stop that connecting lever is blocked by described stopper, now cannot rotate earthed switch rotation axis, when back door is closed, return springs is compressed, stop that connecting lever departs from the spacing draw-in groove of limiting plate, now switch motion can be grounded, now owing to stopping that connecting lever is positioned at locked groove, therefore before open back door, first rotate earthed switch rotation axis make to stop that connecting lever departs from locked groove, ability open back door, usage safety performance is higher.

Embodiment
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Fig. 1-Fig. 9, the utility model discloses a kind of Novel switch cabinet back door locking device, comprise the blocking lock mechanism be arranged in switch cabinet body 1 and the plate 3 be arranged on back door 2, described switch cabinet body 1 offers the perforation 4 of passing for described plate 3, described blocking lock mechanism comprises U-shaped mounting bracket 5, to slide the blocking pin 6 arranged along horizontal direction and described mounting bracket 5 phase, to rotate the earthed switch rotation axis 7 arranged with described mounting bracket 5, described blocking pin 6 is fixedly connected with stopper 8, described earthed switch rotation axis 7 is fixedly installed and stops connecting lever 9, described stopper 8 and described stop connecting lever 9 are all between described mounting bracket 5, described plate 3 offers opening up locked groove 10, described locked groove 10 matches with described stop connecting lever 9, return springs 11 is provided with between described stopper 8 and described mounting bracket 5.
Operation principle: when switch cubicle normally runs, earthed switch is in open position, and back door 2 is closed, blocking pin 6 is retracted in switch cabinet body 1 under the squeezing action of back door 2, and now return springs 11 is compressed, and stops that connecting lever 9 falls in the locked groove 10 of plate 3, back door 2 is locked, and back door 2 cannot be opened; When safeguarding switch cubicle, check and keep in repair, first must close earthed switch, namely rotate earthed switch rotation axis 7, make to stop that connecting lever 9 leaves mortise lock groove 10, ability open back door 2, to safeguard switch cubicle, to check and to keep in repair; After back door 2 is opened, under return springs 11 acts on, blocking pin 6 stretches out outside switch cabinet body 1, stopper 8 slides into blocking position thereupon, i.e. stopper 8 and the stop inconsistent position of connecting lever 9, stopper 8 blocks and stops connecting lever 9, and earthed switch rotation axis 7 cannot be rotated counterclockwise, namely cannot open earthed switch, thus need first closing back door 2 just can open earthed switch.
As shown in Fig. 4, Fig. 5, Fig. 7, Fig. 8, described stopper 8 have match with described stop connecting lever 9 dodge arcwall face, dodge inclined-plane be convenient to blocking pin 6 slide time, when namely stopper 8 slides thereupon, larger friction can not be produced with stop connecting lever 9, reduce wear.
As shown in Fig. 4, Fig. 5, Fig. 7, Fig. 8, the execution mode optimized in the present embodiment is, one end of described blocking pin 6 is fixedly installed limiting section 12, its the other end is sticking department, described return springs 11 is between described limiting section 12 and described stopper 8, limiting section 12 is for carrying out spacing to blocking pin 6, and what prevent its disengaging installing rack wears groove, and sticking department is used for coordinating with locked groove 10.
More than show and describe general principle of the present utility model and principal character and advantage thereof; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; above-described embodiment just illustrates principle of the present utility model with description in explanation; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
