In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1-3, the present invention provides a technical solution: a transformer shell structure with a noise reduction function comprises a transformer main body 1 and a noise reduction frame 3, wherein a first sliding groove 2 is formed in the lower surface of the transformer main body 1, sound absorption cotton 4 is fixedly connected to the inner wall of the noise reduction frame 3, a corrugated plate 5 is fixedly connected to the bottom wall of the noise reduction frame 3, a second sliding groove 20 is formed in the bottom wall of the noise reduction frame 3, an expansion link 7 is arranged between the first sliding groove 2 and the second sliding groove 20, a first spring 8 is sleeved on the outer surface of the expansion link 7, a first sliding block 9 is fixedly connected to the top end of the expansion link 7, the first sliding block 9 is slidably connected with the first sliding groove 2, a second sliding block 6 is fixedly connected to the bottom end of the expansion link 7, the second sliding block 6 is slidably connected with the second sliding groove 20, a groove 10 is formed in the lower surface of the second sliding block 6, a through hole 11 is formed in the, the top fixedly connected with lug 14 of connecting rod 13, the surface cover of connecting rod 13 is equipped with second spring 15, falls the front of making an uproar frame 3 and is provided with shutter 18, and the outer fixed surface of shutter 18 is connected with the handle 19 and falls the inner wall fixedly connected with stopper 21 of making an uproar frame 3.

In this embodiment: the first sliding groove 2 is arranged on the lower surface of the transformer main body 1, the second sliding groove 20 is arranged on the bottom wall of the noise reduction frame 3, so that the telescopic rod 7 and the first spring 8 are stably inserted between the first sliding groove 2 and the second sliding groove 20, since the second spring 15 has a function of pushing up, the groove 10 and the projection 14 are separated by pulling the connection rod 13 downward, the protection door 18 is opened, the telescopic rod 7 and the first spring 8 can be drawn out for replacement, when the transformer main body 1 works, noise or vibration can be generated, the telescopic rod 7 can not only play a good role in jacking the transformer main body 1, when the transformer body 1 moves downwards, the limiting block 21 can prevent the transformer body 1 from moving downwards, and the noise is moved upward to collide the noise with each other, thereby attenuating the noise generated from the transformer body 1.

Specifically, the lower surface of the second slider is provided with a groove 10, the top end of the connecting rod 13 is fixedly connected with a convex block 14, and the groove 10 is attached to the convex block 14.

In this embodiment: the groove 10 is matched with the projection 14, so that the connecting rod 13 is clamped on the lower surface of the second sliding block 6 more stably under the action of the second spring 15.

Specifically, the outer surface of the connecting rod 13 is sleeved with a sponge sleeve 17.

In this embodiment: because the outer surface of the connecting rod 13 is smooth, when the connecting rod 13 is pulled downwards by a hand, good friction force does not exist, and then the connecting rod 13 needs to be pulled downwards by great force, and the sponge sleeve 17 can increase the friction force between the hand and the connecting rod 13, so that the effect of pulling the connecting rod 13 downwards is better.

Specifically, the number of the telescopic rods 7 is three, and the telescopic rods are uniformly distributed in the noise reduction frame 3.

In this embodiment: the transformer main body 1 can be effectively jacked up through the three telescopic rods 7.
