Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of this utility model electrical apparatus release.
Detailed description of the invention
Below in conjunction with the embodiment that accompanying drawing 1 provides, further illustrate the detailed description of the invention of electrical apparatus release of the present utility model.Electrical apparatus release of the present utility model is not limited to the following description.
As shown in Figure 1, this utility model electrical apparatus release, including housing 1, it is fixed in housing 1 and exposed at the handle 5 outside housing 1, with the operating mechanism of handle 1 linkage and electromagnetic system 2, also including the push pedal 3 being pivotably attached in the middle part of housing 1, electromagnetic system 2 and operating mechanism lay respectively at the left and right sides of push pedal 3.
As it is shown in figure 1, operating mechanism includes and the U-shaped bar 6 of handle 5 linkage, snap close 4, tripping 7 and lever 8, one end of tripping 7 connects with U-shaped bar 6, and the other end is pivoted on lever 8；Snap close 4 medium position is pivoted on lever 8, and the other end end arms of snap close 4 is connected with tripping 7 hasp.
Specifically, striker 201 for ejecting when electromagnetic system 2 is provided with dropout towards the side of push pedal 3, the side of push pedal 3 and striker 201 offset, operating mechanism includes snap close 4, and one end end arms of snap close 4 is towards the opposite side of push pedal 3, when electrical apparatus release is threaded off, electromagnetic system 2 ejects striker and hits the side of push pedal 3, push pedal 3 rotation is backed down snap close 4, tripping 7 and snap close 4 and is tripped so that circuit disconnects.After electrical apparatus release is threaded off, the end, one end of lever 8 rotates the opposite side clashing into push pedal 3, and push pedal 3 reset pushes back the striker 201 ejected and electromagnetic system 2 is resetted.
As it is shown in figure 1, one end end arms of snap close 4 is provided with and is easy to contact the contact plane 401 diagonally downward coordinated with the opposite side of push pedal 3.This utility model electrical apparatus release, is provided with in one end end arms of snap close and contacts the contact plane diagonally downward coordinated with push pedal, it is simple to contact cooperation with push pedal so that coordinating between snap close with push pedal is relatively reliable stable；Additionally, due to arrange contact plane diagonally downward so that the angle between two end arms of snap close can diminish, reduce and latch in the internal shared volume of electrical apparatus release, being conducive to the miniaturization of electrical apparatus release, the length of one end end arms of snap close can also shorten relatively, conservation.
