Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated housing technology, specifically a foldable mobile prefabricated house. Background Technology
[0002] Prefabricated houses are a new type of environmentally friendly and economical mobile housing, using light steel as the frame, sandwich panels as the enclosure material, and standard modular assembly. The components are connected by bolts. They allow for convenient and quick assembly and disassembly, achieving universal standardization of temporary buildings. This establishes an environmentally friendly, energy-saving, fast, and efficient construction concept, bringing temporary housing into a realm of serialized development, integrated production, complete supply, and stockable, reusable standardized products.
[0003] In existing prefabricated house construction, the side panels are designed with a folding structure. This allows the side panels to unfold under tension after the top panel is lifted, thus securing the side panels and completing the construction. However, since the overall height of the prefabricated house is usually around three meters, the overall weight is heavy, requiring the use of cranes and other equipment to lift the top panel. This means that the construction of a folding prefabricated house requires the cooperation of multiple people and the crane. However, when there is no lifting equipment available (the prefabricated house is installed indoors, and the lifting equipment cannot enter), the construction difficulty increases. Therefore, we propose a foldable mobile prefabricated house. Utility Model Content
[0004] To address the shortcomings of existing foldable prefabricated houses, this utility model provides a foldable prefabricated house with the advantage that the first and second side panels are opened by rotating a screw, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a foldable prefabricated house, including a base plate, a first side plate and a second side plate movably sleeved on both sides of the base plate, a hinge installed between the first side plate and the second side plate, a top plate movably sleeved on the top of the second side plate, a set of door frame plates installed sequentially at the front and rear ends of the base plate, and a spreading device installed between the first side plate and the second side plate.
[0006] Preferably, a first limiting plate is installed on both sides of the bottom plate and the top plate, and a second limiting plate is fixedly connected to the upper part of the inner side of the first side plate to limit the movement angle of the second side plate, and the end of the second limiting plate is sleeved inside the second side plate.
[0007] Preferably, the spreading device includes two sets of mounting pins, which are installed on one side of the connection between the first side plate and the second side plate. A movable sleeve and a threaded sleeve are respectively fixedly connected to one side of the two sets of mounting pins. A screw is movably sleeved inside the movable sleeve, and the threaded sleeve is threaded onto the outside of the screw.
[0008] Preferably, a groove is provided on the outside of the connection between the first side plate and the second side plate, and a first limiting rod and a second limiting rod are sequentially installed inside the groove. A spring is installed between the first limiting rod and the second limiting rod, and the first limiting rod and the second limiting rod are sleeved together to limit each other.
[0009] Preferably, a limiting pin is installed through the interior of the side of the second side panel, and the limiting pin is movably sleeved inside the side of the door frame panel.
[0010] Preferably, the base plate, the first side plate, the two sets of second side plates and the top plate are assembled with the two sets of door frame plates to form an overall frame of the prefabricated house, and doors and windows are installed inside the door frame plates.
[0011] Preferably, a hanging ring is installed on the upper part of the top plate, and the hanging ring is installed in conjunction with the hook of the crane.
[0012] Compared with existing foldable prefabricated houses, this utility model has the following advantages:
[0013] 1. This foldable prefabricated house has a spreading device installed on the outside of the first and second side panels. By rotating the screw, the screw and the threaded sleeve move in a threaded motion, which can spread the first and second side panels apart. This ensures the ease of opening the prefabricated house and does not require a crane or multiple people to assist in the processing at the same time, thus improving the ease of installation.
[0014] 2. The foldable prefabricated house limits the range of extension between the first side panel and the second side panel through the first limiting plate and the second limiting plate. At the same time, the first limiting rod and the second limiting rod are installed inside the sides of the first side panel and the second side panel. The first limiting rod and the second limiting rod limit the adjustable angle between the first side panel and the second side panel, ensuring that the prefabricated house is convenient to use and position, and preventing the prefabricated house from collapsing later.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A foldable prefabricated house includes a base plate 1, with a first side plate 2 and a second side plate 4 movably sleeved on both sides of the base plate 1. After the first side plate 2 and the second side plate 4 are unfolded, they can support the position of the top plate 5. A hinge 3 is installed between the connection of the first side plate 2 and the second side plate 4. The top plate 5 is movably sleeved on the top of the second side plate 4. A set of door frame plates 7 are installed sequentially at the front and rear ends of the base plate 1. The door frame plates 7 seal the front and rear ends of the base plate 1 and the top plate 5. An opening device 13 is installed between the first side plate 2 and the second side plate 4. After the opening device 13 is installed between the connection of the first side plate 2 and the second side plate 4, the opening device 13 drives the connection of the first side plate 2 and the second side plate 4 to open.
[0023] Please see Figure 3Both sides of the bottom plate 1 and the top plate 5 are equipped with first limiting plates 6. The upper part of the inner side of the first side plate 2 is fixedly connected with a second limiting plate 9 to limit the movement angle of the second side plate 4. The end of the second limiting plate 9 is sleeved inside the second side plate 4. With the first limiting plates 6 installed on both sides of the bottom plate 1 and the top plate 5, when the equipment is turned on and the first side plate 2 and the second side plate 4 are in a vertical state, the second limiting plate 9 limits the position of the second side plate 4. The first limiting plate 6 and the second limiting plate 9 limit the maximum rotation angle of the first side plate 2 and the second side plate 4 to ensure that the first side plate 2 and the second side plate 4 maintain stability during the rotation process.
[0024] Please see Figure 4 The opening device 13 includes two sets of mounting pins 131, which are installed on one side of the connection between the first side plate 2 and the second side plate 4. A movable sleeve 132 and a threaded sleeve 133 are respectively fixedly connected to one side of the two sets of mounting pins 131. A screw 134 is movably sleeved inside the movable sleeve 132, and the threaded sleeve 133 is threadedly sleeved outside the screw 134. By installing the opening device 13 on one side of the first side plate 2 and the second side plate 4, when the control panel is opened, the screw 134 is rotated, and the screw 134 and the threaded sleeve 133 move threadedly, that is, the distance between the movable sleeve 132 and the threaded sleeve 133 is adjusted, which can drive the first side plate 2 and the second side plate 4 to open, ensuring that the structure is opened more conveniently and with less effort.
[0025] Please see Figure 1 A groove is provided on the outside of the connection between the first side plate 2 and the second side plate 4. A first limiting rod 10 and a second limiting rod 11 are installed sequentially inside the groove. A spring 12 is installed between the first limiting rod 10 and the second limiting rod 11. The first limiting rod 10 and the second limiting rod 11 are interlocked and limit each other. The first limiting rod 10 and the second limiting rod 11 are installed on the outside of the first side plate 2 and the second side plate 4. After the first side plate 2 and the second side plate 4 are opened, the first limiting rod 10 and the second limiting rod 11 are retracted. The first limiting rod 10 and the second limiting rod 11 are installed inside the groove. That is, the first limiting rod 10 and the second limiting rod 11 limit the position between the first side plate 2 and the second side plate 4, so as to prevent the connection between the first side plate 2 and the second side plate 4 from loosening, which would cause the prefabricated house to collapse when in use.
[0026] Please see Figure 1 A limiting pin 8 is installed through the inside of the second side plate 4. The limiting pin 8 is movably sleeved inside the door frame plate 7. After the top plate 5 is opened by the first side plate 2 and the second side plate 4, the door frame plate 7 is flipped, and the equipment is formed as a whole. At the same time, the limiting pin 8 is installed on the side of the second side plate 4. The limiting pin 8 limits the position between the door frame plate 7 and the second side plate 4 to ensure the structural integrity.
[0027] Please see Figure 1 The base plate 1, the first side plate 2, the two sets of second side plates 4 and the top plate 5 are assembled with the two sets of door frame plates 7 to form the overall frame of the prefabricated house. Doors and windows are installed inside the door frame plates 7. After the base plate 1, the first side plate 2, the two sets of second side plates 4 and the top plate 5 are assembled with the two sets of door frame plates 7, the main body of the prefabricated house is formed, ensuring the convenience of the prefabricated house construction. At the same time, door frames are installed inside the door frame plates 7 to facilitate the subsequent use of the prefabricated house.
[0028] Please see Figure 5 A hanging ring 14 is installed on the upper part of the top plate 5. The hanging ring 14 is installed in conjunction with the hook of the crane. With the hanging ring 14 installed on the upper part of the top plate 5, during the equipment construction, after the crane hook and the hanging ring 14 are installed together, the crane will move the top plate 5 upward, which can open up the prefabricated house and improve the convenience of the prefabricated house installation and use.
[0029] Working principle: During use, the base plate 1 is placed in the installation area. At the same time, a spreading device 13 is installed on the side of the connection between the first side plate 2 and the second side plate 4. It is installed inside the connection between the two ends by the mounting pin 131. At the same time, the screw 134 is rotated to spread the position between the movable sleeve 132 and the threaded sleeve 133. That is, with the simultaneous operation of two people, the first side plate 2 and the second side plate 4 can be spread open to ensure the convenience of assembly. After the first side plate 2 and the second side plate 4 are moved to a state parallel to the horizontal plane, the first limiting rod 10 and the second limiting rod 11 are installed on the outside of the first side plate 2 and the second side plate 4. The first limiting rod 10 and the second limiting rod 11 limit the position between the first side plate 2 and the second side plate 4. The door frame plate 7 is flipped over. The door frame plate 7 seals the front and rear ends between the base plate 1 and the top plate 5. The limiting pin 8 is installed on the side of the second side plate 4. The limiting pin 8 limits the position between the second side plate 4 and the door frame plate 7.
