[0023] like Figure 1 and Figure 2 As shown, a large-capacity pre-assembled box-type mobile transformer with shock-absorbing function comprises a base 1, a shell 1.1 is fixedly connected to the upper outer wall of the base 1, a bearing plate 1.2 is slidably connected between the inner walls on both sides of the shell 1.1, a connecting block 1.3 is fixedly connected to the upper side wall of the bearing plate 1.2, the upper end of the connecting block 1.3 slides through the shell 1.1 and is fixedly connected to the transformer box 1.4, a shock-absorbing component 2 is arranged in the shell 1.1, and a telescopic component 3 is arranged in the base 1.

[0024] Specifically, Figure 2 and Figure 3As shown, a large-capacity pre-assembled box-type mobile transformer with shock-absorbing function, the shock-absorbing component 2 includes a cylinder 2.1, a sliding seat 2.2, a force plate 2.3, a support rod 2.4, a damper 2.5, a slider 2.6, a first shock-absorbing spring 2.7 and a hinged rod 2.8. The cylinder 2.1 is fixedly connected at the center of the upper outer wall of the base 1, and the sliding seats 2.2 are fixedly connected on both sides of the cylinder 2.1. A force plate 2.3 is slidably provided in the cylinder 2.1, and a support rod 2.4 is fixedly connected to the upper end of the force plate 2.3.

A slider 2.6 is slidably provided in the sliding seat 2.2, and a first shock-absorbing spring 2.7 is abutted between the slider 2.6 and the inner wall of the sliding seat 2.2 on the side away from the cylinder 2.1. An articulated rod 2.8 is hinged on the upper side wall of the slider 2.6, and the other end of the articulated rod 2.8 is hinged to the lower side wall of the bearing plate 1.2. When the movement encounters bumps, the transformer box 1.4 is forced to drive the connecting block 1.3 to move up and down, and the connecting block 1.3 drives the bearing plate 1.2 to move up and down. When the bearing plate 1.2 moves up and down, the two sliders 2.6 will move away from or close to each other under the drive of the articulated rod 2.8, so that the first shock-absorbing spring 2.7 is deformed to buffer the impact force.

The other end of the connecting arm 3.5 It extends into the accommodating groove 3.4 and is equipped with wheels 3.6. When the transformer box 1.4 needs to be moved, the driving motor 3.2 is started, and the output shaft of the driving motor 3.2 can drive one of the rotating rods 3.1 to rotate. After being transmitted by the two transmission gears 3.3, the other rotating rod 3.1 can be driven to rotate. When the rotating rod 3.1 rotates, it will drive the connecting arm 3.5 to rotate. When the connecting arm 3.5 rotates, the wheels 3.6 in the accommodating groove 3.4 can be extended and the base 1 can be propped up to move. After moving to the destination, the driving motor 3.2 is reversed. After transmission, the connecting arm 3.5 drives the wheels 3.6 to gradually retract into the accommodating groove 3.4, so that the bottom wall of the base 1 touches the ground, forming a stable support, avoiding displacement, and being more stable.

[0026] Specifically, Figure 2 As shown, a large-capacity pre-assembled box-type mobile transformer with shock-absorbing function is provided.

One end of the second shock-absorbing spring 1.6 is fixedly connected to the base 1 and the other end is fixedly connected to the bearing plate 1.2. When the bearing plate 1.2 moves up and down due to bumps, the second shock-absorbing spring 1.6 will undergo elastic deformation to further buffer the impact force of the road surface.

[0027] Specifically, Figure 1 As shown, a large-capacity pre-assembled box-type mobile transformer with a shock-absorbing function is provided. A protective box 4 is fixedly connected to the outer wall of one side of the shell 1.1. A battery is arranged in the protective box 4. The driving motor 3.2 is electrically connected to the battery, and the battery provides power for the driving motor 3.2.

[0028] Specifically, Figure 1 As shown, a large-capacity pre-assembled box-type mobile transformer with a shock-absorbing function is provided with a traction mechanism 5 on the outer wall of the base 1 away from the protective box 4, which is used to pull the base 1 to move.

When the movement encounters bumps, the transformer box 1.4 is forced to drive the connecting block 1.3 to move up and down, and when the connecting block 1.3 moves up and down, it drives the bearing plate 1.2 to move up and down. When the bearing plate 1.2 moves up and down, it compresses the third shock-absorbing spring 1.6, and the third shock-absorbing spring 1.6 undergoes elastic deformation to buffer and reduce shock, and the bearing plate 1 When the support plate 1.2 moves up and down, the two sliders 2.6 will move away from or close to each other under the drive of the hinge rod 2.8, so that the first shock-absorbing spring 2.7 will deform to buffer the impact force. The support rod 2.4 can drive the load-bearing plate 2.3 to move up and down as the load-bearing plate 1.2 moves up and down. When the load-bearing plate 2.3 moves up and down, the second shock-absorbing spring 2.11 reduces shock. The damper 2.5 can provide a certain resistance to enable the load-bearing plate 1.2 to drive the transformer box 1.4 to quickly stabilize in the bumps, fully protecting the transformer box 1.4 from the impact force of the road surface. After moving to the destination, the drive motor 3.2 is reversed. After transmission, the connecting arm 3.5 drives the wheel 3.6 to gradually retract into the accommodating groove 3.4, so that the bottom wall of the base 1 touches the ground, forming a stable support, avoiding displacement, and being more stable.
