[0047] like Figures 1 to 4 As shown, an embodiment of the utility model provides an earthquake-resistant safety structure of a mobile house, comprising: a house body 1 and a supporting base plate 6; further comprising: a first shock-absorbing part, arranged on the supporting base plate 6; a second shock-absorbing part, arranged on the first shock-absorbing part; cooperating with the first shock-absorbing part to achieve the purpose of multi-directional shock absorption; a supporting part, arranged at the top of the second shock-absorbing part and connected to the house body 1; to support the house body 1; a limiting part, arranged on the house body 1.

[0048] In the embodiment of the utility model, the first shock absorbing part is provided to achieve shock absorption in the horizontal direction, thereby reducing the horizontal vibration of the house body 1. At the same time, the second shock absorbing part is provided to achieve shock absorption in the vertical direction, thereby reducing the vertical vibration of the house body 1. The two parts cooperate to reduce the vibration of the house body 1, thereby preventing the mobile house from tipping over.

[0049] like Figures 1 to 4 As shown, the first shock absorbing part includes: a second connecting plate 401, which is arranged on the supporting base plate 6, and the top end of which is connected to the second shock absorbing part; a first buffer member, which is arranged on the supporting base plate 6 and connected to the second connecting plate 401; a second buffer member, which is arranged on the supporting base plate 6, connected to the second connecting plate 401, and cooperates with the first buffer member to achieve shock absorption in the horizontal direction.

[0050] In the embodiment of the utility model, when aftershocks occur, a certain stability is ensured by fixing the support base plate 6 on the ground; the first buffer is used to buffer the vibration in the front-to-back direction in the horizontal direction, and the second buffer is used to buffer the vibration in the left-to-right direction in the horizontal direction, thereby achieving overall vibration buffering in the horizontal direction.

[0051] like Figures 1 to 4 As shown, the first buffer member includes: a first sliding hole 402, which is opened on the second connecting plate 401; a first connecting rod 405, which is inserted into the first sliding hole 402; a first side plate 403, which is arranged at both ends of the supporting bottom plate 6; a first movable groove 404, which is opened on the inner side of the first side plate 403; a first connecting block 406, which slides in the first movable groove 404 and is connected to one end of the first connecting rod 405; a first damper 407, one end of which is connected to the first connecting block 406, and the other end is connected to the inner wall of the first movable groove 404.

[0052] like Figures 1 to 4 As shown, the second buffer member includes: a second sliding hole 501, which is opened on the second connecting plate 401, perpendicular to the direction of the first sliding hole 402, and located above the first sliding hole 402; a second connecting rod 504, which slides in the second sliding hole 501; a second side plate 502, which is arranged at both ends of the supporting bottom plate 6 and is perpendicular to the first side plate 403; a second movable groove 503, which is opened on the inner side of the second side plate 502; a second connecting block 505, which slides in the second movable groove 503 and is connected to one end of the second connecting rod 504; a second damper 506, one end of which is connected to the second connecting block 505, and the other end is connected to the inner wall of the second movable groove 503.

[0053] In the embodiment of the utility model, when aftershocks occur and generate forces in the front-to-back direction, the second connecting plate 401 will be driven to move along the direction of the second connecting rod 504. When the second connecting plate 401 moves, the first connecting rod 405 will be driven to move, thereby driving the first connecting block 406 to slide along the first movable groove 404. At this time, the first connecting block 406 will pull the first damper 407, and the first damper 407 will absorb the vibration, thereby driving the second connecting plate 401 to slow down the vibration through the first connecting rod 405, thereby reducing the vibration of the house body 1; so as to achieve shock absorption in the moving direction of the first connecting block 406;

[0054] When aftershocks occur and generate forces in the left and right directions, the second connecting plate 401 will be driven to move along the direction of the first connecting rod 405. When the second connecting plate 401 moves, the second connecting rod 504 will be driven to move, thereby driving the second connecting block 505 to slide along the second movable groove 503. At this time, the second connecting block 505 will pull the second damper 506, and the second damper 506 will absorb the vibration, thereby driving the second connecting plate 401 to slow down the vibration through the second connecting rod 504, thereby reducing the vibration of the room body 1; thereby achieving shock absorption in the moving direction of the second connecting block 505.

[0055] In reality, horizontal forces can be divided into two vertical forces, thereby achieving shock absorption in the entire horizontal direction.

[0056] like Figures 1 to 4 As shown, the second shock absorbing part includes: a first support plate 301, which is provided in four groups, and the bottom ends of the four groups of the first support plates 301 are connected to the second connecting plate 401; a spring damper 302, which is provided in four groups, corresponding to the four groups of the first support plates 301, and one end of the four groups of the spring dampers 302 is connected to the bottom end of the support part.

[0058] like Figures 1 to 4 As shown, the support portion includes: a first connecting plate 101, which is arranged at the bottom end of the room body 1, the top end of which is connected to the limiting portion, and the bottom end of which is connected to the spring damper 302.

[0059] In the embodiment of the utility model, the first connecting plate 101 is connected to the house body 1 after multiple shock absorption, so as to ensure the stability of the house body 1.

[0060] like Figures 1 to 4 As shown, the limiting part includes: a first connecting ear 201, which is arranged on the house body 1; a second connecting ear 203, which is arranged on the first connecting plate 101; and a chain 202, one end of which is connected to the first connecting ear 201, and the other end of which is connected to the second connecting ear 203.

[0061] In the embodiment of the utility model, when the aftershock is large and causes the house body 1 to still shake greatly, the first connecting ear 201 and the second connecting ear 203 are connected by the chain 202, which connects the house body 1 and the first connecting plate 101 together, thereby improving the vibration resistance of the house body 1.

[0062] Working principle: When aftershocks occur and generate forces in the front-to-back direction, the second connecting plate 401 will be driven to move along the direction of the second connecting rod 504. When the second connecting plate 401 moves, the first connecting rod 405 will be driven to move, thereby driving the first connecting block 406 to slide along the first movable groove 404. At this time, the first connecting block 406 will pull the first damper 407, and the first damper 407 will absorb the vibration, thereby driving the second connecting plate 401 to slow down the vibration through the first connecting rod 405, thereby reducing the vibration of the room body 1; so as to achieve shock absorption in the moving direction of the first connecting block 406;

[0063] When aftershocks occur and generate left-right forces, the second connecting plate 401 will be driven to move along the direction of the first connecting rod 405. When the second connecting plate 401 moves, the second connecting rod 504 will be driven to move, thereby driving the second connecting block 505 to slide along the second movable groove 503. At this time, the second connecting block 505 will pull the second damper 506, and the second damper 506 will absorb the vibration, thereby driving the second connecting plate 401 to slow down the vibration through the second connecting rod 504, thereby reducing the vibration of the house 1; thereby achieving shock absorption in the moving direction of the second connecting block 505. In reality, horizontal forces can be divided into two vertical forces, thereby achieving shock absorption in the entire horizontal direction.

[0064] When vertical vibration occurs, the spring damper 302 reduces the vibration effect of the room body 1. It cooperates with the first damper 407 and the second damper 506 to achieve all-round anti-vibration.

[0065] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
