[0002] Prefabricated cabins are prefabricated building modules or components, including wall panels, floors, roofs and other components. Prefabricated cabins have many advantages, such as optimizing production efficiency, reducing construction time, and reducing labor costs. For integrated prefabricated cabins, during transportation, the prefabricated cabins are easily damaged due to bumps in the transport compartment.

[0003] Among the existing patent documents, there is a patent application with an application date of 2018.10.02 and an authorization announcement number of CN108616068B, titled "A prefabricated cabin body and a prefabricated cabin". The prefabricated cabin body of this patent includes a bottom plate, an air inlet is provided on the bottom plate, an air supply device is connected to the air inlet, the air supply device is connected to an air supply duct, the air supply duct is provided with an air outlet for supplying air to each screen cabinet, there are multiple air outlets, and the multiple air outlets are spaced apart in the length direction of the air supply duct.

[0004] However, during transportation, the bottom of the patent will come into contact with the transport carriage, and it is easy for the bumps to be transferred to the prefabricated cabin body through the carriage, which may cause the prefabricated cabin body to become loose during assembly and cause damage to the prefabricated cabin body. Summary of the invention

[0005] The purpose of the invention is to solve the problems existing in the above-mentioned background technology and to propose a lightweight earthquake-resistant prefabricated cabin.

[0006] To achieve the above purpose, the invention provides the following technical solutions:

[0007] A lightweight, earthquake-resistant prefabricated cabin comprises cabin side walls, a cabin ceiling and a cabin base. The cabin ceiling and the cabin base are respectively fixedly mounted on the top and bottom of the cabin side walls. Earthquake-resistant support mechanisms are respectively hidden at the four corners of the cabin side walls. The prefabricated cabin is lifted as a whole by the earthquake-resistant support mechanisms to exert an earthquake-resistant effect in a transport compartment.

[0008] By adopting the above scheme, before transportation, the prefabricated cabin body is lifted as a whole by operating the anti-seismic support mechanism. At this time, the cabin body base is not in contact with the transport carriage, which can play an anti-seismic and shock-absorbing effect, and can effectively prevent the transmission of shocks through the carriage into the prefabricated cabin body due to bumps, so as to better protect the prefabricated cabin body. Moreover, the anti-seismic support mechanisms are hidden at the four corners of the cabin body side wall, respectively, which can effectively improve the space utilization rate of the prefabricated cabin body.

[0009] Further as a preferred embodiment, the seismic support mechanism includes a positioning tripod, which is fixedly mounted at the inner wall corners of the side wall of the cabin, and is rotated with the positioning tripod as a reference to cooperate with a lifting assembly, a seismic frame is movably mounted on the bottom of the lifting assembly, and support feet are movably mounted inside the seismic frame through the seismic assembly, and a support base is fixedly mounted on the bottom of the support feet.

[0010] The lifting assembly comprises a lifting turntable, which is fixedly equipped with a rotating slider through a lifting screw, and the rotating slider is rotatably matched with the top end of the earthquake-resistant frame.

[0011] The anti-seismic component comprises a guide rod which is fixedly assembled in the anti-seismic frame, a guide block fixed on the supporting foot is slidably matched on the guide rod, and an anti-seismic spring is sleeved on the guide rod.

[0012] By adopting the above scheme, before transportation, by rotating the lifting turntable, the rotating slider can be driven to rotate through the lifting screw, thereby driving the seismic frame to descend, so that the support base is lower than the cabin base, and the seismic support mechanism will lift the prefabricated cabin as a whole. Then, during transportation, the seismic component can play a seismic effect in the transport compartment; when in use, by rotating the lifting turntable, the rotating slider can be driven to rotate through the lifting screw, thereby driving the seismic frame to rise, so that the support base is higher than the cabin base, and then it can be placed for use.

[0013] As a further preferred solution, the seismic support mechanism also includes a seismic adjustment component, which is fixedly mounted on one side of the seismic frame, and the seismic strength of the seismic component is changed by the seismic adjustment component.

[0014] The seismic adjustment component includes two reference seats, an adjustment screw is fixed between the two reference seats, an adjustment screw is rotatably fitted with a combination of an adjustment nut and an adjustment seat, a lower abutment seat is rotatably fitted on the adjustment seat, and an upper abutment seat corresponding to the lower abutment seat is fixed on one side of the supporting foot, and the upper abutment seat is located in an avoidance groove opened on one side of the seismic frame.

[0015] By adopting the above scheme, during transportation, the seismic strength of the seismic assembly can be changed according to the degree of bumpiness of the road conditions. When adjusting, the adjusting nut is moved up and down along the adjusting screw by using a wrench in conjunction with the adjusting nut, and the lower abutment seat contacts the upper abutment seat, which can drive the supporting foot to rise through the upper abutment seat, thereby changing the compression state of the seismic spring and realizing the adjustment of the seismic strength.

[0016] Further as a preferred solution, the seismic support mechanism also includes an adsorption positioning structure, which is fixedly assembled on one side of the seismic frame, and the adsorption positioning structure is used to improve the stability of the support base when it contacts the transport carriage.

[0017] The adsorption positioning structure includes a mounting seat, on which an adsorption sleeve is fixed, and the adsorption sleeve is sealed with an adsorption bolt, and the adsorption sleeve is connected to the support foot through an air suction hose, and the air suction hose is located in the avoidance groove 2 opened on one side of the seismic frame;

[0018] The interiors of the supporting feet and the supporting base are both hollow, and a sealing ring is bonded to the lower surface of the supporting base.

[0019] By adopting the above solution, before transportation, after the sealing ring of the support base contacts the transport carriage, the gas inside the support foot and the support base can be extracted by rotating the adsorption bolt outward, so that the air pressure inside the support foot and the support base becomes smaller, which can promote the sealing ring to be fully adsorbed and fixed to the transport carriage, thereby ensuring stability and reliability during transportation.

[0020] As a further preferred solution, a drain rack is fixedly installed between the side wall of the cabin and the base of the cabin, and the drain rack

[0021] There are many water filtering tanks throughout the building.

[0022] By adopting the above solution, the water in the side wall of the cabin can flow into the cabin base through the drain rack to avoid

[0023] Water accumulates in the side walls.

[0024] As a further preferred solution, a door is movably installed on one side of the side wall of the cabin;

[0025] A drainage cavity is provided inside the cabin base, and one side of the drainage cavity is connected with a drainage pipe.

[0026] By adopting the above solution, the water that flows into the cabin base through the drain rack can be discharged through the drain pipe.

[0027] Compared with the prior art, the invention has the following beneficial effects:

[0028] By operating the anti-seismic support mechanism, the prefabricated cabin is lifted as a whole. At this time, the cabin base is not in contact with the transport carriage, which can play an anti-seismic and shock-absorbing effect, and can effectively prevent the bumps from being transmitted through the carriage to the prefabricated cabin, so as to better protect the prefabricated cabin.

[0029] The anti-seismic support mechanisms are hidden at the four corners of the side walls of the cabin, which can effectively improve the space utilization rate of the prefabricated cabin; the anti-seismic support mechanism can adjust the stiffness of its own shock-absorbing spring, and can change its anti-seismic strength to cope with different road conditions in turn; the anti-seismic support mechanism adopts negative pressure adsorption to be positioned in the transport compartment, which is more stable and reliable during transportation.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the invention.

[0048] Please refer to Figure 1-16 , the present invention provides a technical solution:

[0049] A lightweight, earthquake-resistant prefabricated cabin comprises a cabin side wall 1, a cabin ceiling 2 and a cabin base 4. The cabin ceiling 2 and the cabin base 4 are respectively fixedly mounted on the top and bottom of the cabin side wall 1. Earthquake-resistant support mechanisms 5 are respectively hidden at the four corners of the cabin side wall 1. The prefabricated cabin is lifted as a whole by the earthquake-resistant support mechanism 5 to exert an earthquake-resistant effect in the transport compartment.

[0050] Before transportation, the anti-seismic support mechanism 5 is operated to raise the prefabricated cabin as a whole. At this time, the cabin base 4 is not in contact with the transport carriage, which can play an anti-seismic and shock-absorbing effect, and can effectively prevent the vibration from being transmitted through the carriage into the prefabricated cabin, thereby better protecting the prefabricated cabin. Moreover, the anti-seismic support mechanisms 5 are hidden at the four corners of the cabin side wall 1, respectively, which can effectively improve the space utilization rate of the prefabricated cabin.

[0051] Specifically, the seismic support mechanism 5 includes a positioning tripod 501, which is fixedly installed at the inner wall corner of the cabin side wall 1, and is rotated with the positioning tripod 501 as a reference. A lifting component 51 is rotatably installed at the bottom of the lifting component 51, and a seismic frame 502 is movably installed inside the seismic frame 502 through the seismic component 52. A supporting foot 503 is movably installed at the bottom of the supporting foot 503 through the seismic component 52, and a supporting base 504 is fixedly installed at the bottom of the supporting foot 503.

[0052] The lifting assembly 51 includes a lifting turntable 5101 , and the lifting turntable 5101 is fixedly equipped with a rotating slider 5103 through a lifting screw 5102 . The rotating slider 5103 is rotatably matched with the top end of the earthquake-resistant frame 502 .

[0053] The anti-seismic component 52 includes a guide rod 5201 , which is fixedly assembled in the anti-seismic frame 502 , and a guide block 5202 fixed on the anti-seismic frame 503 is slidably matched on the guide rod 5201 , and an anti-seismic spring 5203 is sleeved on the guide rod 5201 .

[0054] Before transportation, by rotating the lifting turntable 5101, the lifting screw 5102 can drive the rotating slider 5103 to rotate, thereby driving the seismic frame 502 to descend, so that the support base 504 is lower than the cabin base 4, and the seismic support mechanism 5 will lift the prefabricated cabin as a whole. Then, during transportation, the seismic component 52 can play a seismic effect in the transport compartment; when in use, by rotating the lifting turntable 5101, the lifting screw 5102 can drive the rotating slider 5103 to rotate, thereby driving the seismic frame 502 to rise, so that the support base 504 is higher than the cabin base 4, and then it can be placed for use.

[0055] Specifically, the anti-seismic support mechanism 5 further includes an anti-seismic adjustment component 53 , which is fixedly mounted on one side of the anti-seismic frame 502 , and the anti-seismic strength of the anti-seismic component 52 is changed by the anti-seismic adjustment component.

[0056] The seismic adjustment component 53 includes two reference seats 5301, between which an adjustment screw 5302 is fixed, on which an adjustment screw 5302 is rotatably fitted a combination of an adjustment nut 5303 and an adjustment seat 5304, on which a lower abutment seat 5305 is rotatably fitted, and on one side of the supporting foot 503 an upper abutment seat 5306 corresponding to the lower abutment seat 5305 is fixed, and the upper abutment seat 5306 is located in an avoidance groove 5307 opened on one side of the seismic frame 502.

[0057] During transportation, the seismic strength of the seismic-resistant component 52 can be changed according to the degree of bumpiness of the road conditions. When adjusting, the adjusting nut 5303 is cooperated with the adjusting nut 5303 by a wrench to move the adjusting nut 5303 up and down along the adjusting screw 5302, and the lower abutment seat 5305 contacts the upper abutment seat 5306, so that the supporting foot 503 can be lifted up through the upper abutment seat 5306, thereby changing the compression state of the seismic-resistant spring 5203 and realizing the adjustment of the seismic strength.

[0058] Specifically, the anti-seismic support mechanism 5 further includes an adsorption positioning structure 54 , which is fixedly assembled on one side of the anti-seismic frame 502 , and the adsorption positioning structure 54 is used to lift the support base 504 to ensure stability when in contact with the transport carriage.

[0059] The adsorption positioning structure 54 includes a mounting seat 5401, on which an adsorption sleeve 5402 is fixed, and an adsorption bolt 5403 is sealed in the adsorption sleeve 5402. The adsorption sleeve 5402 is connected to the support foot 503 through an air suction hose 5404, and the air suction hose 5404 is located in the avoidance groove 2 5405 opened on one side of the earthquake-resistant frame 502;

[0060] The interiors of the supporting foot 503 and the supporting base 504 are both hollow, and a sealing ring 505 is bonded to the lower surface of the supporting base 504 .

[0061] Before transportation, after the sealing ring 505 of the support base 504 contacts the transport compartment, the gas inside the support foot 503 and the support base 504 can be extracted by rotating the adsorption bolt 5403 outward, so that the air pressure inside the support foot 503 and the support base 504 becomes smaller, which can promote the sealing ring 505 to be fully adsorbed and fixed to the transport compartment, thereby ensuring stability and reliability during transportation.

[0062] Specifically, a drain rack 3 is fixedly mounted between the cabin side wall 1 and the cabin base 4 , and a plurality of water filter grooves 301 are formed through the drain rack 3 .

[0063] The water in the side wall 1 of the cabin can flow into the cabin base 4 through the drain rack 3, so as to avoid water accumulation in the side wall 1 of the cabin.

[0064] Specifically, a door 101 is movably installed on one side of the cabin side wall 1;

[0065] A drainage cavity 401 is provided inside the cabin base 4 , and a drainage pipe 402 is connected to one side of the drainage cavity 401 .

[0066] The water that flows into the cabin base 4 through the drain rack 3 can be discharged through the drain pipe 402.

[0067] Working principle of the present invention:

[0068] During transportation, the anti-seismic support mechanism 5 is operated to raise the prefabricated cabin as a whole. At this time, the cabin base 4 is not in contact with the transport carriage, which can play an anti-seismic and shock-absorbing effect. It can effectively prevent the vibration from being transmitted through the carriage into the prefabricated cabin, and can better protect the prefabricated cabin. Moreover, the anti-seismic support mechanism 5 is hidden at the four corners of the cabin side wall 1, which can effectively improve the space utilization rate of the prefabricated cabin.

[0069] Before transportation, by rotating the lifting turntable 5101, the lifting screw 5102 can drive the rotating slider 5103 to rotate, thereby driving the seismic frame 502 to descend, so that the support base 504 is lower than the cabin base 4, and the seismic support mechanism 5 will lift the prefabricated cabin as a whole. Then, during transportation, the seismic component 52 can play a seismic effect in the transport compartment; when in use, by rotating the lifting turntable 5101, the lifting screw 5102 can drive the rotating slider 5103 to rotate, thereby driving the seismic frame 502 to rise, so that the support base 504 is higher than the cabin base 4, and then it can be placed for use.

[0070] During transportation, the seismic strength of the seismic-resistant component 52 can be changed according to the degree of bumpiness of the road conditions. When adjusting, the adjusting nut 5303 is cooperated with the adjusting nut 5303 by a wrench to move the adjusting nut 5303 up and down along the adjusting screw 5302, and the lower abutment seat 5305 contacts the upper abutment seat 5306, so that the supporting foot 503 can be lifted up through the upper abutment seat 5306, thereby changing the compression state of the seismic-resistant spring 5203 and realizing the adjustment of the seismic strength.

[0071] Before transportation, after the sealing ring 505 of the support base 504 contacts the transport compartment, the gas inside the support foot 503 and the support base 504 can be extracted by rotating the adsorption bolt 5403 outward, so that the air pressure inside the support foot 503 and the support base 504 becomes smaller, which can promote the sealing ring 505 to be fully adsorbed and fixed to the transport compartment, thereby ensuring stability and reliability during transportation.

[0072] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all changes within the meaning and range of equivalents of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
