Detailed ways

Below, the utility model will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, on the premise of not conflicting, the various embodiments or technical features described below can be combined arbitrarily to form new implementations. example.

As shown in Figure 1, the dual-frequency switching generator includes a generator body 1 arranged on a mounting base, and a shock absorbing seat is provided at the bottom of the mounting base, and the shock absorbing seat includes an upper shock absorbing pad 2, a support ring 3 and the lower shock pad 4, the bottom of the upper shock pad 2 is provided with an upper accommodating groove 5, the top of the lower shock pad 4 is provided with a lower accommodating groove 6, and the upper accommodating groove 5 A sleeve 7 is provided, and a piston rod 8 is arranged in the lower accommodation groove 6, and the piston rod 8 is fitly inserted in the sleeve 7;

A baffle 9 is provided at the bottom of the sleeve 7 , and a spring 10 is provided between the baffle 9 and the lower accommodating groove 6 . The vibration generated by the operation of the generator body 1 is transmitted to the shock-absorbing seat, and the upper shock-absorbing pad 2 can absorb part of the energy, causing the upper shock-absorbing pad 2 to displace or vibrate, and form a downward pressure on the casing 7, thereby making the piston The rod 8 moves toward the inside of the casing 7, so that on the one hand, the piston rod 8 will squeeze the air in the casing 7 to achieve shock absorption, and on the other hand, the baffle 9 will press down the spring 10, so that the spring 10 is compressed, The shock absorption is realized, the structure is reasonable, the installation is reliable, and the effect of buffering and shock absorption is effectively improved.
