This creates safety hazards. Furthermore, these houses are prone to tilting after vibration, and if adjustments are not made in time, it can significantly affect their normal use. Additionally, they are prone to lateral displacement during vibration, further impacting their functionality and ultimately severely affecting their overall performance. Summary of the Invention

[0053] During earthquake resistance testing: Workers move the prefabricated house 7 to its designated position using four pulleys 8, and install the air conditioner outdoor unit 9 on the upper surface of the prefabricated house 7. Then, the steel structure earthquake-resistant equipment for the prefabricated building is installed in the designated position. At this time, the four support plates 1 are fixed to the ground with bolts. When the prefabricated house 7 vibrates due to external forces, the prefabricated house 7 will move downwards. The movement of the prefabricated house 7 drives the four connecting blocks 201 to move, the movement of the connecting blocks 201 drives the support plate 202 to move, the movement of the support plate 202 drives the first sliding plate 203 to move, the movement of the first sliding plate 203 drives the top rod 204 to move, and the downward movement of the top rod 204 compresses the sliding block 205, causing the sliding block 205 to move along the fixed rod 3, thereby compressing the corresponding sleeve 209 and the first elastic element 210. The sleeve 209 and the first elastic element 210 then dampen the vibration, converting kinetic energy into elastic potential energy for shock absorption, thereby reducing the vibration of the prefabricated house 7 and the air conditioner outdoor unit 9.

[0054] When tilting occurs: The prefabricated house 7 is prone to tilting due to vibration. When the prefabricated house 7 tilts, it causes the connecting rod 6 to move. The movement of the connecting rod 6 causes the two fixed rods 3 to move. The movement of the two fixed rods 3 causes the corresponding electronic level 5 to move. The two electronic level 5 then detect the prefabricated house 7. When the prefabricated house 7 tilts, the left or right side will be lower than the horizontal line. At this time, the two first electric actuators 207 on the lower side are activated, causing the corresponding sliders 208 to move upward. The movement of the two sliders 208 causes the corresponding pressing plates 206 to move. The movement of the two pressing plates 206 causes the corresponding sliding blocks 205 to move. The movement of the two sliding blocks 205 causes the corresponding fixed rods 3 to move. The movement of the two fixed rods 3 causes the corresponding electronic level 5 to move, thus keeping the two electronic level 5 level again. In this way, the movement of the two fixed rods 3 keeps the prefabricated house 7 level and prevents it from tilting.

[0055] During reinforcement: When the prefabricated house 7 vibrates due to external force, causing the corresponding sliding block 205 to move, the movement of the four sliding blocks 205 drives the corresponding pressing plate 206 to move. The movement of the four pressing plates 206 each compresses one of the second sliding plates 302, causing the four second sliding plates 302 to move downward. The movement of the four second sliding plates 302 drives the corresponding first fixing block 303 to move downward. At the same time, the movement of the four second sliding plates 302 drives the corresponding first fixing plate 304 to move downward, thereby stretching the corresponding second elastic element 306. At this time, the four first fixing blocks 303 move downward and insert into the ground, thereby reinforcing the prefabricated house 7 through the four first fixing blocks 303, so that the prefabricated house 7 remains stable.

[0056] When locking: When the prefabricated house 7 vibrates due to external force, the movable parts 81 on the two pulleys 8 on the left are easily affected by external force and suddenly open, which can easily cause the prefabricated house 7 to move and shift laterally. At this time, the two second electric actuators 401 are controlled to drive the corresponding top blocks 402 to move downward. The movement of the two top blocks 402 drives the corresponding irregular plate 408 to move. At this time, the two irregular plates 408 rotate about a second connecting shaft 411, which in turn pulls the corresponding third elastic element 410 and the corresponding fourth elastic element. The movement of the two irregularly shaped plates 408 causes the corresponding first connecting shaft 407 to move downwards. The movement of the first connecting shaft 407 causes the corresponding vertical rod 404 to move downwards. The movement of the vertical rod 404 causes the corresponding buckle 405 to move downwards, thereby causing each of the two buckles 405 to lock a round rod 406, thus limiting the two movable parts 81 on the left and locking the two pulleys 8 on the left. This prevents the two movable parts 81 on the left from suddenly opening due to external force, which could cause the prefabricated house 7 to shift laterally.

[0057] During protection: When the prefabricated house 7 vibrates due to external forces, the air conditioner outdoor unit 9 is very likely to move. When the air conditioner outdoor unit 9 moves, it is protected by the protective frame 503 and damped by the four fifth elastic elements 504, thereby preventing the air conditioner outdoor unit 9 from moving over a large range and falling. When the air conditioner outdoor unit 9 moves, in order to prevent the air conditioning pipe 91 from detaching from the prefabricated house 7, the air conditioning pipe 91 is limited by the fourth fixing plate 507. When the air conditioner outdoor unit 9 moves, the second fixing block 505 moves synchronously, thereby compressing the sixth elastic element 508, thereby damping the vibration through the sixth elastic element 508, thus preventing the air conditioning pipe 91 from detaching from the prefabricated house 7 and preventing the air conditioning pipe 91 from pulling the prefabricated house 7 and causing deformation of the prefabricated house 7.
