For solving the above problems, the specific technical scheme of the utility model is as follows: a motor protection and manual unlocking device for an electric mechanism is characterized in that a motor, a gear reduction box and an electromagnetic structure are fixedly connected to a support, a stop iron core is arranged below the support in parallel, an angle plate is vertically sleeved and connected on the outer circumference of the stop iron core, one end of the stop iron core is in contact with a micro switch, an iron core spring is wound on the outer circumference of the stop iron core, the iron core spring is stopped at the angle plate, the control end of the manual unlocking spring is in contact with the angle plate, and a crank arm of the gear reduction box is sleeved in a round hole at one end of the angle plate and moves.

The electromagnetic structure is as follows: the electromagnetic iron rack is welded with the support, and the electromagnet is arranged on the electromagnetic iron rack. After the power-on is triggered, the electromagnet is attracted, the angle plate arranged on the iron core moves along with the iron core, the spring is compressed, the microswitch is triggered by the angle plate, and the motor is started.

The lower end face of the support is vertically connected with a plurality of support plates, the support plates are a support plate I, a support plate II and a support plate III from left to right, and the stop iron core sequentially penetrates through the support plate I, the support plate II, the support plate III and the electromagnet frame and then contacts with the gear reduction box.

The iron core spring starts from the support plate II and ends at the angle plate.

The utility model discloses the beneficial effect who brings does: the installation is simple, the installation error is avoided, the misoperation is prevented, the motion track is accurate, and the damage is not easy to occur; branching; through the arrangement of the stop iron core and the iron core spring, the movement track is stable, and the failure rate is reduced.

Fig. 1 is a schematic structural diagram of a motor protection and manual unlocking device of an electric mechanism.

Detailed Description

As shown in figure 1, the motor protection and manual unlocking device for the electric mechanism is characterized in that a motor 1, a gear reduction box 4 and an electromagnetic structure are fixedly connected onto a support 2, a stop iron core 8 is arranged below the support 2 in parallel, an angle plate 10 is vertically sleeved and connected onto the outer circumference of the stop iron core 8, one end of the stop iron core 8 is in contact with a micro switch 7, an iron core spring 9 is wound on the outer circumference of the stop iron core 8, the iron core spring 9 is stopped at the angle plate 10, the control end of a manual unlocking spring 3 is in contact with the angle plate 10, and a crank arm of the gear reduction box 4 is sleeved in a round hole at one end of the angle plate.

The electromagnetic structure is as follows: the device comprises an electromagnet frame 5 and an electromagnet 6, wherein the electromagnet frame 5 is connected with a support 2 in a welding mode, and the electromagnet 6 is installed on the electromagnet frame 5.

The lower end face of the support 2 is vertically connected with a plurality of support plates, the support plates are a support plate I2-1, a support plate II2-2 and a support plate III2-2 from left to right, and the stop iron core 8 sequentially penetrates through the support plate I2-1, the support plate II2-2, the support plate III2-2 and the electromagnet frame 5 and then contacts with the gear reduction box 4.

The iron core spring 9 starts from the support plate II2-2 and ends at the angle plate 10.

The motor 1, the gear reduction box 4, the electromagnet support 5 and the microswitch 7 are fixed together through the bracket 2; the electromagnet 6 is arranged on the electromagnet frame 5; the right end of the stop iron core 8 penetrates through the electromagnet support 5, the outer circumference of the stop iron core 8 is vertically sleeved and connected with an angle plate 10, and the left end of the stop iron core is sleeved on the support 2; the crank arm of the gear reduction box 4 is sleeved in a round hole at one end of the angle plate 10 and can move transversely; two ends of the iron core spring 9 are respectively arranged on the bracket 2 and the angle plate 10; when the electromagnet 6 receives power, the stop iron core 8 and the angle plate 10 move rightwards, the microswitch 7 is compressed to switch the states, and the motor 1 receives power to operate; when the circuit is powered off, the motor 1 stops moving, the iron core spring 9 drives the stop iron core 8 to move leftwards, and due to the damping effect of the gear reduction box 4, the stop iron core 8 returns to the leftmost side within a few seconds to complete locking.
