Abstract
The utility model discloses a PLC high-voltage combination-switch door-opening mechanism, comprising a door body. The PLC high-voltage combination-switch door-opening mechanism is characterized by that a rotating handle is arranged on a front upper end of the door body, and the rotating handle passes the door body and is in connection with a handle umbrella-shaped gear on a back side of the door body; a dwang is arranged on the back side of the door body and an upper end of the dwang is equipped with a masthead umbrella-shaped gear. The masthead umbrella-shaped gear engages with the handle umbrella-shaped gear. A shifting block is arranged on a lower end of the dwang and the shifting block is in connection with a permanent magnetic breaker. The dwang is arranged on the back side of the door body by a plurality of buckles and can rotate by 180 degrees. By rotating the handle umbrella-shaped gear arranged on the back side, the handle umbrella-shaped gear engages with the umbrella-shaped gear of the dwang inside the door, the dwang connects a structure of the permanent magnetic breaker, an electrical change-over switch can shut off a power directly when the door is open and casualty accidents caused by power being on when the door is open can be avoided.
Description
Technical field:
The utility model relates to the high voltage switchgear field, relates in particular to a kind of PLC high pressure unit switch door-opening mechanism.
Background technology:
PLC high pressure unit switch is installed in the cabinet usually, is usually used in the switch control of high-voltage fence, because operational environment voltage is high; Energising is breakneck when therefore opening the door; Cause operating personnel's injures and deaths easily, PLC high pressure unit switch in the past, its cabinet door place does not have safety device; The inside work of still can switching on was abnormally dangerous when the cabinet door was opened.Therefore imagination provides a kind of new device, and direct outage can not be worked when electric reversing switch was opened the door, and solved this problem.
The utility model content:
The purpose of the utility model just provides a kind of PLC high pressure unit switch door-opening mechanism, solves PLC high pressure unit switch in the past, and its cabinet door place does not have safety device, the inside work of still can switching on when the cabinet door is opened, breakneck problem.
The technical scheme that the utility model adopts is:
A kind of PLC high pressure unit switch door-opening mechanism comprises a body, it is characterized in that: upper end, door body front is equipped with swing handle, and swing handle passes a body and is connected with the handle bevel gear at the door body back side; The door body back side is equipped with dwang, and the dwang upper end is equipped with the masthead bevel gear, and masthead bevel gear and handle bevel gear are meshing with each other, and the dwang lower end is equipped with shifting block, and shifting block is connected to permanent-magnet breaker.
Said dwang is installed in a body back side through some buckles, and dwang can 180 ° of rotations.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is installed bevel gear through the swing handle back side; Be meshing with each other with the bevel gear of dwang in the door; Dwang is connected to the structure of permanent-magnet breaker, and electric reversing switch is directly cut off the power supply when opening the door, and the accident that energising causes casualties when avoiding opening the door takes place.
Description of drawings:
Accompanying drawing 1 is the utility model door body Facad structure sketch map;
Accompanying drawing 2 is the utility model door body structure sketch map.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:
A kind of PLC high pressure unit switch door-opening mechanism comprises a body 1: door body 1 positive upper end is equipped with swing handle 2, and swing handle 2 passes a body 1 and is connected with handle bevel gear 3 at the door body back side; Door body 1 back side is equipped with dwang 4; Dwang 4 upper ends are equipped with masthead bevel gear 5; Masthead bevel gear 5 is meshing with each other with handle bevel gear 3, and dwang 4 lower ends are equipped with shifting block 6, and shifting block 6 is connected to permanent-magnet breaker 7; Dwang 4 is installed in a body 1 back side through some buckles, and dwang 4 can 180 ° of rotations.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous improvement and modification all should fall within the protection range of the utility model.
