detailed description:

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below through specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and not intended to limit the scope of the present invention. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present invention.

As shown in Figure 1, this specific embodiment adopts the following technical solutions: it includes an upper casing 1, a lower casing 2, a moving iron core 3, a fixed iron core 4, a guide rod 5, a guide sleeve 6, a return spring 7, a driver 8. Shock-absorbing airbag 9, shock absorber 10; the inside of the upper casing 1 is provided with a moving iron core 3, the inside of the lower casing 2 is provided with a fixed iron core 4, and the lower casing 1 The side is connected with the lower casing 2, the bottom of the fixed iron core 4 is connected to the inner side wall of the lower casing 2 through two shock absorbers 10 and the shock absorbing airbag 9, the moving iron core 3, the fixed iron core 4 A guide sleeve 6 is installed on the outer side wall, and the guide rod 5 is connected in the guide sleeve 6. Drivers 8 are installed on both inner side walls of the lower housing 2, and the driving rod of the driver 8 passes through the connecting block. Connected with the guide sleeve 6 of the moving iron core 3, the two drivers 8 and the coils installed on the fixed iron core 4 are electrically connected to the power supply through wires, the return spring 7 is sleeved on the guide rod 5, and the The return spring 7 is arranged between the two guide sleeves.

Further, the moving iron core 3 and the fixed iron core 4 are provided with longitudinal cooling holes.

Further, the outer surfaces of the shock-absorbing airbag 9 and the shock absorber 10 are provided with insulating sleeves.

The working principle of this specific embodiment is: when in use, the moving iron core 3 is driven to move by coil energization, and when the moving iron core moves, the guide sleeve 6 moves on the guide rod 5 to improve stability, so that the moving iron core High stability, at the same time, after the coil is energized, the driver 8 is also energized, and the driver 8 drives the moving iron core 3 to move downward, which can improve and speed up the speed and efficiency of the pull-in, and after the driver 8 is powered off, the driver 8 realizes automatic Extended reset, and the reset spring 7 can realize auxiliary reset, easy to use, easy to operate, improve stability, and when the fixed iron core is stressed, the shock absorber 9 and the shock absorber 10 can realize force buffering in a small range, The wear and tear of the fixed iron core is small, and the contact performance thereof can be guaranteed, and the efficiency is high.
