Further, the cabinet door push rod mechanism comprises a mounting plate, movable push rods, a pressure spring and an elastic cylindrical pin, wherein the movable push rods are respectively arranged in guide plates on two sides of the mounting plate, the pressure spring is sleeved on the movable push rods between the two guide plates in the front of the mounting plate, one end of the pressure spring is abutted against the end face of the middle guide plate, and the other end of the pressure spring is in contact with the elastic cylindrical pin on the movable push rods.
Further, the cabinet door driving mechanism comprises a mounting baffle, a door panel operation hole mounting nut and a threaded cover plate, the mounting baffle is concave, two ends of the concave correspond to the two movable push rods, and the threaded cover plate is mounted at the bottom of the concave through the door panel operation hole mounting nut.
Furthermore, when the operation cabinet door is closed, the installation baffle begins to touch the movable push rod, the elastic cylindrical pin inwards compresses the pressure spring, and when the cabinet door is completely closed, the stroke of the movable push rod meets the requirement of unlocking the chassis vehicle operation device.
Further, the operation cabinet door is opened, the installation baffle is separated from the movable push rod, the pressure spring resets to drive the movable push rod to reset, the movable push rod is separated from the chassis, and the locking state of the chassis operation device is restored.
The utility model has the advantages that:
1. compared with the prior art, the utility model is more perfect, has remarkable universality and is suitable for various nonstandard centrally-mounted switch cabinets;
2. the main body parts of the pushing unlocking device are cut by laser, bent by numerical control, assembled and formed in an overlapping mode, the design precision is high, and the unlocking effect is obvious.
Drawings
Fig. 1 is an installation schematic diagram of the central-mounted type circuit breaker chassis propulsion unlocking device suitable for different cabinet depths of the utility model;
fig. 2 is the utility model discloses a well put formula circuit breaker chassis car propulsion unlocking device schematic structure suitable for different cabinets are dark.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in 1,2, the utility model discloses a well-arranged circuit breaker chassis propulsion unlocking device suitable for different cabinets are dark requires the design according to chassis closing door operating characteristic, including mounting panel 1, movable push rod 2, pressure spring 3, elasticity cylindric lock 4, door plant handle hole mounting nut 6, thread cover plate 7.
Mobilizable movable push rod 2 is set up respectively in the deflector of both sides on the mounting panel 1, has cup jointed the pressure spring 3 on the movable push rod 2 between two deflectors in being located the mounting panel 1, and 3 one end of pressure spring are supported and are leaned on middle deflector terminal surface, and the other end contacts with the elasticity cylindric lock 4 on the movable push rod 2, constitutes cabinet door push rod mechanism.
The installation baffle 5 is concave, two ends of the concave correspond to the two movable push rods 2, and the bottom of the concave is provided with a threaded cover plate 7 through a door plate operation hole installation nut 6 to form an operation cabinet door driving mechanism. The cabinet door driving mechanism is arranged on the door plate of the circuit breaker chamber.
The feedback elasticity of the pressure spring 3 is tested by closing the operation cabinet door, so that the door closing is not influenced, whether the stroke of the movable push rod 2 meets the unlocking requirement is tested, and if the requirement is not met, or the cabinet door is difficult to close, the pressure spring 3 and the movable push rod 2 can be replaced.
The utility model discloses an operation process:
1. the operation cabinet door is closed, and installation baffle 5, door plant handle hole mounting nut 6, thread cover 7 are close to advancing device, begin to touch movable push rod 2 when installation baffle 5, and elasticity cylindric lock 4 inwards compresses pressure spring 3, and when the cabinet door is closed completely, 2 strokes of movable push rod satisfy unblock chassis car operating means.
