Abstract
The utility model discloses an interlocking device for a switch cabinet door (1). The interlocking device comprises a cabinet door (1) and a valve upper bracket (2). The cabinet door (1) is provided with a lock ring (11). The utility model is characterized in that, a rotary lock pin (41) that can be screwed into the lock ring (11) is hinged to a side wall of the switch cabinet, a connecting rod (3) is mounted between the valve upper bracket (2) and the rotary lock pin (41), the valve upper bracket (2) drives the connecting rod (3), which pulls the rotary lock pin (41) to be screwed out of the lock ring (11). By disposing the valve upper bracket to drive the rotary lock pin to stretch into or screw out of the lock ring, the interlocking device for the switch cabinet door provided by the utility model plays a role of opening or closing the cabinet door.
Description
Technical field
The utility model relates to the electric equipment field, the interlock of especially a kind of switch cubicle chamber door.
Background technology
The circuit breaker of the switch cubicle that uses does not have interlock at present, no matter the interior circuit breaker of switch cubicle is closing a floodgate still at gate-dividing state, the door of breaker chamber can be opened, and using, safeguard, all having potential safety hazard when overhauling, might touch charged position and cause potential safety hazard.Coefficient of safety is lower.
The utility model content
For improving problems of the prior art, the utility model proposes the interlock of a kind of switch cubicle chamber door, be opened easily problem in order to solve the breaker chamber door.
The interlock of the switch cubicle chamber door that the utility model proposes, comprise chamber door and valve upper bracket, the chamber door is provided with lock ring, be hinged with the rotation lock pin that can screw in described lock ring on the sidewall of described switch cubicle, between described valve upper bracket and the described rotation lock pin connecting rod is installed, described connecting rod can be driven and be spurred described rotation lock pin and screw out described lock ring by described valve upper bracket.
Preferably, described rotation lock pin is provided with pull bar, is connected with extension spring between described pull bar and the described chamber door.
Preferably, the pin head of described rotation lock pin is arc.
The interlock of the switch cubicle chamber door that the utility model proposes stretches into or screws out lock ring by valve upper bracket pulling rotation lock pin is set, and has played the effect of unlatching or close chamber's door.
Description of drawings
Be clear the utility model and the beneficial effect thereof described, in conjunction with the following drawings to being described in detail of embodiment, wherein:
Fig. 1 is the structural representation of the interlock of the switch cubicle chamber door that provides of the utility model embodiment.
Embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical or similar label is represented identical or similar elements or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
As shown in Figure 1, the interlock of the switch cubicle chamber door 1 that the utility model proposes, comprise chamber door 1 and valve upper bracket 2, chamber door 1 is provided with lock ring 11, be hinged with the rotation lock pin 41 that can screw in lock ring 11 on the sidewall of switch cubicle, between valve upper bracket 2 and the rotation lock pin 41 connecting rod 3 is installed, connecting rod 3 can be driven and pulling rotation lock pin 41 back-out lock rings 11 by valve upper bracket 2.
End by articulated linkage 3 on the valve upper bracket 2, the other end of connecting rod 3 is hinged with rotation lock pin 41, when valve upper bracket 2 is opened, drivening rod 3 pulling rotation lock pins 41 are deviate from from lock ring 11, when valve upper bracket 2 is closed, the pin head of connecting rod 3 driven rotary lock pins 41 falls in the lockhole, and chamber door 1 is carried out locking.
Further, rotation lock pin 41 is provided with pull bar 42, is connected with extension spring 5 between pull bar 42 and the described chamber door 1.Can rotation lock pin 41 be dropped in the lock ring 11 auxiliary connecting rod 3 by extension spring 5.
Further, the pin head of rotation lock pin 41 is arc, and the pin head of arc is the easier lock ring 11 that falls into when rotated, saves the space.
The interlock of the switch cubicle chamber door that the utility model proposes stretches into or screws out lock ring by valve upper bracket pulling rotation lock pin is set, and has played the effect of unlatching or close chamber's door.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: under the situation that does not break away from principle of the present utility model and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
