Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model Monostable permanent magnetic mechanism;
Fig. 2 is the cutaway view of the utility model Monostable permanent magnetic mechanism.
Embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1 and Figure 2, at Monostable permanent magnetic mechanism of the present utility model, comprise guide rod 3, main tripping spring 2, upper magnet yoke 4, permanent magnet 6, outer yoke 8, divide-shut brake coil 9 and lower yoke 10.
Moving iron core 5 is set with and is fixed on guide rod 3 outsides, and guide rod 3 is through moving iron core 5, and guide rod 3 is fixedly connected with moving iron core 5.Divide-shut brake coil 9 is looped around moving iron core 5 outsides, between moving iron core 5 and divide-shut brake coil 9, is provided with inner yoke 7, and outer yoke 8 is wrapped in divide-shut brake coil 9 and inner yoke 7 outsides.Upper magnet yoke 4 and lower yoke 10 are separately fixed at the two ends up and down of outer yoke 8, between inner yoke 7 and outer yoke 8, are provided with permanent magnet 6, and permanent magnet 6 has the magnetic force of the moving iron core 5 of absorption.Main tripping spring 2 is socketed on guide rod 3, and the lower end of main tripping spring 2 is connected with the upper end of upper magnet yoke 4, and moving iron core 5 can move between upper magnet yoke 4 and lower yoke 10.Main tripping spring 2 provides the power that upper magnet yoke 4 is moved down, and main tripping spring 2 is Compress Spring.
Further, be provided with auxiliary tripping spring 11 between moving iron core 5 and lower yoke 10, auxiliary tripping spring 11 is enclosed within guide rod 3 outsides.The two ends of auxiliary tripping spring 11 are against respectively in moving iron core 5 and lower yoke 10, and auxiliary tripping spring 11 provides the power that iron core 5 is moved up, and auxiliary tripping spring 11 is Compress Spring.Auxiliary tripping spring 11 can be shared the power of a part of main tripping spring 2, can reduce like this volume of main tripping spring 2, further saves space.
Further, the upper end of guide rod 3 is also provided with nut 13 and spring compressor 1, and main tripping spring 2 is between spring compressor 1 and upper magnet yoke 4, and nut 13 is threaded with guide rod 3 and holddown spring cap 1.By the position of adjusting nut 13, regulate the initial compression length of main tripping spring 2, thereby regulate opening characteristic.
