Abstract
The invention provides a latching and interlocking device of a handcart type feed mechanism. The device comprises a baffle plate, a crank arm, a square shaft, a square sleeve, a latching electromagnet and a stop pin. The device is characterized in that the stop pin is a plate which is fixedly connected on the square sleeve, the face width of the plate is greater than the distance between the centre axis of the latching electromagnet iron core of the latching electromagnet and the revolving bottom dead center of the plate. The innovation of the invention lies in that the original stop pin with a circular cross-section shape is changed into the plate with a certain width, thus, when the control on the feed mechanism to take out a cranking handle is finished during the working, even if the electricity goes off or the latching electromagnet burns out and the like at the movement, the latching electromagnet iron core can led to automatically reset; since the working face at the back of the plate-type stop pin locates on the scalable track of the latching electromagnet iron core all the time, thus the path to counterclockwise running of the square shaft caused by the reset of the latching electromagnet iron core can be prevented, the timely reset of the baffle plate and further the close of the cranking handle hole can be ensured and the potential safety hazard of the later operation can be eliminated.

[summary of the invention]
For solving the problems referred to above that prior art exists, the present invention aims to provide the locking interlock of the novel handcart-type propulsive mechanism of a kind of structure, even this locking interlock runs into outage in operating process or latching electromagnet such as burns out at situation, the latching electromagnet iron core occurring automatically resets, baffle plate also can in time reset and seal the delthyrium of shaking the hand, thereby eliminates the potential safety hazard of back operation.
For achieving the above object, the present invention has adopted following technical scheme: the structure of the structure of the locking interlock of this handcart-type propulsive mechanism, comprise baffle plate, connecting lever, square shaft, square cover, latching electromagnet and backing pin, it is characterized in that: described backing pin is one and is fixedly connected on the flat board that described side puts that this dull and stereotyped face width is greater than the distance between the extremely dull and stereotyped rotation lower dead center in the latching electromagnet iron core axis of described latching electromagnet.
During concrete enforcement, described backing pin is a fan-shaped two-sided flat board.
During concrete enforcement, described backing pin and side's cover are fixedly connected for welded type.
Beneficial effect: compared with prior art, the present invention innovates part and is original cross sectional shape is circular backing pin, be modified into flat board with certain width, for example fan-shaped two-sided flat board, and make this dull and stereotyped face width greater than the distance between the extremely dull and stereotyped rotation lower dead center in the latching electromagnet iron core axis of described latching electromagnet, therefore, during operation, press lower baffle plate, crank handle is inserted in the delthyrium of shaking the hand, rotate crank handle, make connecting lever, square shaft, side's cover and backing pin are by clockwise rotating, finish when propulsive mechanism control taken out crank handle,, and cause latching electromagnet iron core automatically reset (stretching out) even this moment occurs situations such as outage or latching electromagnet burn out, because flat backing pin Background Job face is positioned on the flexible track of latching electromagnet iron core all the time, thereby avoided cutting the path that square shaft inhour is rotated, guaranteed in time resetting of baffle plate and seal the delthyrium of shaking the hand, eliminated the potential safety hazard of back operation because of the latching electromagnet iron core resets.In addition, backing pin and side cover adopt welded type to be fixedly connected, and have solved to improve the above two and adopt and be threaded, and square cover material requires high, and particularly square hole processing is loaded down with trivial details, not only wastes time and energy the problem that also needs special purpose machine tool just can finish.
