Embodiment Construction
[0036] Below in conjunction with each accompanying drawing, the present invention is described in detail.
[0037] Such as Figure 1~3 As shown, an electric operation interlocking structure, including:
[0038] Substrate 1;
[0039] The micro switch 3 is relatively fixed with the substrate 1;
[0040] The push rod 4 is slidably arranged relative to the base plate 1, and the push rod 4 has a notch 19 matched with the operation hole 20 of the propulsion mechanism 5;
[0041] The rotating plate 2 is rotatably installed on the base plate 1, and the rotating plate 2 has a first arm 7 that cooperates with the micro switch 3 and a second arm 13 that cooperates with the push rod 4;
[0042] The torsion spring 11 is used to make the first arm 7 abut against the micro switch 3 when the rotating plate 2 is not subjected to external force;
[0043] The return spring 15 is used to push the push rod 4 so that the push rod 4 always abuts against the second arm 13;
[0044] The unlocking...

The invention discloses an electrical operation interlocking structure. The structure comprises a substrate, a microswitch, a push rod, a rotary plate, a torsion spring, a return spring and an unlocking piece. The push rod is arranged relative to the substrate in a sliding mode and provided with a notch matched with an operation hole of a pushing mechanism; the rotary plate is rotationally installed on the substrate and provided with a first arm matched with the microswitch and a second microswitch matched with the push rod; the torsion spring is used for the first arm to abut against the microswitch; the return spring is used for pushing the push rod so that the push rod can abut against the second arm all the time; the unlocking piece is rotationally installed on the rotary plate and used for driving the rotary plate to rotate, so that the first arm is separated from the microswitch, and meanwhile the push rod is moved, so the concave of the push rod is aligned to the operation hole. The push rod abuts against the second arm all the time through the push rod and the return spring which are matched. Compared with the prior art, the problems that an interlocking plate is too long and production efficiency is not high can be solved, production cost can be reduced, assembly is more convenient, and operation is more convenient.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to an electric operation interlocking structure. Background technique [0002] At present, the existing electric operation interlocking mechanism (application number is 201020254871.3) includes a base plate, a traction plate, an unlocking plate, an auxiliary switch for controlling the closing power supply to the electric operation mechanism, and an interlocking plate interlocked with the drawer propulsion mechanism. The auxiliary switch is installed on the base plate, the interlocking plate has a chute, and the base plate has a positioning sliding column. The interlocking plate is slidably installed on the base plate through the chute embedded in the positioning sliding column, and the traction plate is installed through the traction plate shaft on the base plate. On the base plate, there is a torsion spring between the traction plate and the base plate. On the traction plate, ther...
