[0040] Reference Figures 1-7For the embodiment of the utility model, propose a prefabricated component, including first connecting piece 1, first connecting piece 1 has first connecting portion 101 and second connecting portion 102, first connecting piece 1 is sequentially arranged with several, first connecting portion 101 and the second connecting portion 102 of adjacent another first connecting piece 1 form limiting hole 103, first connecting portion 101 has fixed ring 104, second connecting piece 2 is relatively rotatory and slidingly arranged in limiting hole 103, second connecting piece 2 slides into or slides out limiting hole 103 after sliding, second connecting piece 2 has sliding slot 201, third connecting piece 3 is slidingly arranged in sliding slot 201, third connecting piece 3 has first clamping slot 301, fourth connecting piece 4 is slidingly arranged in fixed ring 104, fourth connecting piece 4 has first clamping portion 401, fourth connecting piece 4 slides, and first clamping portion 401 is clamped with first clamping slot 301.

[0041] In the embodiment, a plurality of first connecting pieces 1 are sequentially arranged according to the layout requirements of the side plate or the top plate of the carriage, so that the fixed ring 104 of the first connecting portion 101 corresponds to the second connecting portion 102 of the adjacent another first connecting piece 1, forming the limiting hole 103. When arranging, the spacing between the first connecting pieces 1 should be uniform to ensure the stability of the carriage structure and the reliability of the connection. Insert the second connecting piece 2 into the limiting hole 103, pay attention to the insertion direction, so that the second connecting piece 2 can rotate and slide freely in the limiting hole 103. After insertion, check the flexibility of rotation and sliding. The first clamping slot 301 of the third connecting piece 3 is used for clamping operation with the fourth connecting piece 4. Insert the fourth connecting piece 4 into the fixed ring 104 of the first connecting portion 101 and make it slide in the fixed ring 104. When sliding to the appropriate position, make the first clamping portion 401 accurately clamped with the first clamping slot 301 of the third connecting piece 3, complete the assembly of the carriage part structure of the box car. The assembly process of the prefabricated house is similar, and corresponding adjustments are made according to the size and requirements of the house structure parts.

[0042] The rotation and sliding function of the second connecting piece 2 relative to the limiting hole 103 makes it possible to flexibly adjust the structure layout inside the carriage according to different cargo loading requirements and space utilization requirements when assembling the carriage. For example, when large cargo needs to be loaded, the space inside the carriage can be expanded by adjusting the position of the second connecting piece 2; when different types of goods need to be separated, temporary separation structures can be built by combining the second connecting piece 2 and other connecting pieces, improving the flexibility of the carriage. The connection mode of the entire prefabricated component in the carriage assembly process is simple and easy to understand, and the operator can quickly install it. When the vehicle is maintained or the carriage parts are replaced, the prefabricated component can be easily disassembled, greatly shortening the maintenance time and cost. For example, when the side plate of the carriage is damaged and needs to be replaced, only the relevant connecting pieces need to be sequentially disassembled, and the side plate can be easily replaced without the need to disassemble the entire carriage structure.

[0043] The first connecting piece 1 and the second connecting piece 2 are connected through the cooperation of the limiting hole 103, and the third connecting piece 3 and the fourth connecting piece 4 are connected through the cooperation of the limiting hole 103. The stable connection of the car structure is provided. During the driving of the vehicle, even if it is subjected to external forces such as extrusion and vibration of the goods, the car structure composed of prefabricated components can maintain good stability, ensuring the safe transportation of goods. At the same time, this stable structure also helps to prolong the service life of the car and reduce the number of repairs caused by structural deformation.

[0044] Due to the different types of goods that may be transported during the transportation process of the box truck, as well as the upgrading of vehicles, the reusability of prefabricated components is particularly important. This prefabricated component can be reused in different vehicles or different transportation tasks, reducing the manufacturing cost of the car. When a truck is scrapped, the prefabricated components on its car can be removed and installed on a new vehicle after simple detection and maintenance, realizing effective use of resources.

[0045] In the construction process of prefabricated houses, the rotation and sliding function of the second connecting piece 2 relative to the limiting hole 103 can flexibly adjust the structural layout and spatial form of the house according to different architectural design requirements and site conditions. For example, when designing houses with different house types, the length of the first connecting piece 1 can be changed to change the size and shape of the room, adjust the overall structure of the house, and make it better adapt to the terrain and improve land utilization. The assembly of prefabricated houses usually needs to be completed quickly on the construction site, and the installation and disassembly of this prefabricated component greatly improves the construction efficiency. Compared with traditional construction methods, it reduces the time and labor cost of on-site construction. When the house needs to be relocated or modified, the prefabricated components can be easily disassembled and reassembled into a new house structure, realizing the reuse and sustainable development of the house.

[0046] For prefabricated houses, structural stability is crucial. The stable connection of the first connecting piece 1 and the second connecting piece 2, as well as the cooperation of the third and fourth connecting pieces 4, provides reliable support and connection for the house structure. In the event of natural disasters such as earthquakes and wind disasters, this stable structure can effectively resist external forces and protect the lives of occupants. At the same time, good structural stability also helps to reduce deformation and damage to the house during long-term use, prolonging the service life of the house.

[0047] With the acceleration of urbanization and the changing needs of people for living environment, the reusability of prefabricated houses has important practical significance. Such prefabricated components can be reused in different construction sites or different projects, reducing the waste of building materials and the generation of construction waste. When the construction demand of an area changes, prefabricated houses can be disassembled and transported to other places for reassembly, adapting to different development needs and conforming to the concept of green building and sustainable development.

[0048] Further, the axial direction of the limiting hole 103 is perpendicular to the length direction of the first connecting piece 1.

[0049] In this embodiment, the perpendicular arrangement of the axial direction of the limiting hole 103 makes the movement of the second connecting piece 2 in the limiting hole 103 more stable. When subjected to external force, the second connecting piece 2 is not easy to deviate or shake along the length direction of the first connecting piece 1, thereby ensuring the stability of connection with other connecting pieces such as the third and fourth connecting pieces 4. During the driving process of the box-type truck, the vibration and bumping of the vehicle will not easily cause the loosening or misalignment between the connecting pieces, ensuring the integrity of the truck structure and the safe transportation of goods. In prefabricated houses, this stable connection can effectively resist lateral forces and torsional forces caused by natural disasters such as earthquakes and wind disasters, improving the overall safety of the house.

[0050] The vertically arranged limiting hole 103 also increases the contact area and friction between the connecting pieces, further improving the reliability of the connection. After assembly is completed, the connecting pieces can better support and constrain each other, reducing the risk of structural deformation or damage caused by improper sliding or rotation of the connecting pieces.

[0051] Further, the first connecting part 101 and the second connecting part 102 each have a limiting slot 105, adjacent two limiting slots 105 form a limiting hole 103, the limiting slot 105 has a first limiting clamping part 106, the first limiting clamping parts 106 of adjacent two first connecting pieces 1 form a giving slot 107, the second connecting piece 2 has a second limiting clamping part 202, the second connecting piece 2 is configured to slide, the second limiting clamping part 202 is located in the giving slot 107 or moves out of the giving slot 107, the first limiting clamping part 106 and the second limiting clamping part 202 are mutually clamped or unclamped after the second connecting piece 2 is rotated.

[0052] In this embodiment, the limiting groove 105 of the first connecting piece 1 cooperates with the second connecting piece 2 to form a precise limiting structure. When the second connecting piece 2 slides and rotates in the limiting hole 103, the limiting groove 105 can effectively limit its movement trajectory, so that it will not appear excessive deviation or shaking. The first limiting clamping part 106 of the adjacent two first connecting pieces 1 forms a giving slot 107, which interacts with the second limiting clamping part 202 of the second connecting piece 2. When the second connecting piece 2 slides, the second limiting clamping part 202 is located in the giving slot 107. This clamping design makes the second connecting piece 2 be stably supported and limited in all directions, greatly enhancing the stability of the connection.

[0053] In the actual application of the box truck carriage, when the vehicle drives on the bumpy road, this stable connection structure can ensure that the parts of the carriage will not loosen or separate due to vibration, ensuring the integrity of the carriage and the safe transportation of goods. In prefabricated houses, it can effectively resist the influence of natural forces such as wind and earthquake on the structure, so that the house can maintain stability under various environmental conditions.

[0054] When the second connecting piece 2 rotates, the first limiting clamping part 106 and the second limiting clamping part 202 are clamped with each other, forming a reliable locking mechanism. This clamping method increases the connection strength and friction between the connecting pieces, so that they can better withstand various external forces such as tension, pressure and shear force. After the prefabricated component is assembled, the connecting pieces are tightly combined to form an organic whole structure, improving the anti-deformation ability and carrying capacity of the whole prefabricated component. For example, when the structure is subjected to the pressure of heavy goods or the upper structure of the building, this clamping structure can ensure that the connecting pieces will not slide or dislocate relative to each other, ensuring the stability and safety of the structure.

[0055] The design of the giving slot 107 provides a clear position guide for the installation and operation of the second connecting piece 2. During assembly, the operator can easily align the second limiting clamping part 202 of the second connecting piece 2 with the giving slot 107 for installation, ensuring that the second connecting piece 2 can accurately slide into the limiting hole 103 and reach the predetermined position. This precise position control makes the assembly process more efficient and accurate, reducing the rework and adjustment work caused by inaccurate installation position.

[0056] In the face of various external forces, such as the impact of goods on the box truck compartment, wind and earthquake disasters suffered by prefabricated houses, and other natural disasters, the prefabricated component can evenly disperse external forces to the entire structural system through the coordinated action of the limiting groove 105 and the clamping part, avoiding structural damage caused by excessive local stress. This structural design makes the prefabricated component have better seismic and wind resistance performance, can maintain the integrity and stability of the structure in harsh environmental conditions, and provides more reliable safety protection for users. During the use of the prefabricated component, dangerous situations such as component shedding and structural instability caused by excessive gaps or insecure connections between connecting parts will not occur. This not only improves the safety of the prefabricated component itself, but also reduces the safety risks to surrounding personnel and the environment during use.

[0057] Further, the first limiting clamping part 106 and the second limiting clamping part 202 are arranged in several rows, and a second clamping groove 109 is formed between two adjacent first limiting clamping parts 106, and a third clamping groove 203 is formed between two adjacent second limiting clamping parts 202. The second connecting part 2 is configured such that after the second connecting part 2 is rotated, the first limiting clamping part 106 slides into or out of the third clamping groove 203, and the second limiting clamping part 202 slides into or out of the second clamping groove 109.

[0058] In this embodiment, the arrangement of multiple first limiting clamping parts 106 and second limiting clamping parts 202, and the cooperation of the corresponding clamping grooves, form a large number of clamping points. When connecting, these clamping points work together to greatly increase the stability and reliability of the connection. Compared with the traditional single clamping method, it can more effectively resist the action of various external forces and prevent relative displacement between connecting parts. For example, when a prefabricated house is subjected to horizontal forces such as earthquakes, multiple clamping points can evenly distribute forces to prevent local connection failure from causing overall structural instability and ensure the safety of the house.

[0059] For box truck compartments, which are frequently subjected to vibration and impact during transportation, multiple clamping points can ensure tight connection between the various components of the truck compartment and prevent loosening due to long-term jolting, ensuring safe transportation of goods and overall structural integrity of the truck compartment.

[0060] The second clamping groove 109 and the third clamping groove 203 formed by the adjacent limiting clamping parts are precisely matched with the corresponding clamping part size. When the second connecting piece 2 is rotated, the clamping part can be accurately slid into the clamping groove to achieve a close fit. This precise fit not only improves the stability of the connection, but also reduces the gap and looseness caused by inaccurate connection. The reduction of the gap reduces the possibility of impurities such as dust and moisture entering the connection part 303, thereby delaying the corrosion and wear of the connection part 303 and prolonging the service life of the prefabricated component. In actual application, whether it is the long-term use of prefabricated houses or the harsh transportation environment of box-type truck compartments, this precise connection can remain stable and ensure that the performance of the structure is not affected.

[0061] The operation mode of the second connecting piece 2, which can be first slid and then rotated, provides greater flexibility for the installation process. In the early stage of installation, the second connecting piece 2 is inserted into the limiting hole 103 by sliding, which facilitates the adjustment of its position to adapt to different installation scenarios and requirements. Then, the rotation is performed to realize the cooperation of the clamping part and the clamping groove. This step-by-step operation makes the installation process smoother and reduces installation errors caused by improper one-time operation. When subsequent adjustments or maintenance of the prefabricated component are required, the convenience of this step-by-step operation can also be utilized. First, the second connecting piece 2 is rotated to disengage the clamping part from the clamping groove, and then it is slid out for adjustment or replacement of parts, greatly reducing the operation difficulty and cost and improving the work efficiency.

[0062] Further, the third connecting piece 3 has a guide surface 302 located on one side of the first clamping groove 301 for guiding the first clamping part 401 to slide into the first clamping groove 301.

[0063] In this embodiment, the guide surface 302 of the third connecting piece 3 is located on one side of the first clamping groove 301, providing clear guidance for the first clamping part 401 of the fourth connecting piece 4 to slide into the first clamping groove 301. During assembly, the operator does not need to perform complex alignment operations, but only needs to move the fourth connecting piece 4 towards the third connecting piece 3. After the first clamping part 401 contacts the guide surface 302, it will naturally slide along the guide surface 302 towards the first clamping groove 301, greatly improving the accuracy and efficiency of the clamping.

[0064] For example, in the rapid assembly process of a box-type truck compartment, the worker can more quickly complete the clamping operation of the fourth connecting piece 4 and the third connecting piece 3, reducing the time wasted due to difficult alignment and improving the overall production efficiency. For the construction of prefabricated houses, the construction progress can also be accelerated, especially when large-scale prefabricated component assembly is performed, and the guiding effect is more significant.

[0065] The presence of the guide surface 302 reduces the requirement for the skill level of the operator. Even inexperienced workers can successfully complete the clamping of the first clamping part 401 with the first clamping groove 301 with the help of the guide surface 302. This makes the installation of prefabricated components more simple and easy to understand, reduces the problem of poor connection caused by human operation errors, and improves the stability of the installation quality.

[0066] When the first clamping part 401 slides into the first clamping groove 301 along the guide surface 302, the guide surface 302 can guide the first clamping part 401 to enter the clamping groove in a more stable manner, avoiding hard collision and friction between the first clamping part 401 and other parts of the third connecting piece 3. This can effectively reduce the wear and tear of the connecting piece during clamping, prolonging the service life of the prefabricated component.

[0067] For long-term use of box-type truck carriages and prefabricated houses, reducing wear and tear means less maintenance and replacement costs, improving overall economic efficiency. At the same time, the reduction of wear and tear also helps to maintain the tightness and stability of the connection, ensuring that there will be no loosening or connection failure due to wear and tear of the connecting piece during use.

[0068] Further, the fourth connecting piece 4 is slidingly and rotatably arranged in the fixed ring 104, the fourth connecting piece 4 has a connecting groove 402, the first clamping part 401 is located in the connecting groove 402, the third connecting piece 3 has a connecting part 303, the first clamping groove 301 and the guide surface 302 are located on the connecting part 303, and the connecting part 303 is configured to be clamped into the connecting groove 402 after the fourth connecting piece 4 slides.

[0069] In this embodiment, the sliding and rotating function of the fourth connecting piece 4 makes it easier to operate during installation. The operator can first make the fourth connecting piece 4 slide in the fixed ring 104, and then make appropriate rotating adjustment according to the position and angle of the third connecting piece 3, so that the first clamping part 401 can smoothly slide into the first clamping groove 301, and at the same time, the connecting part 303 of the third connecting piece 3 is clamped into the connecting groove 402. This installation method is simple and easy to understand, reduces the complexity of the installation steps, and improves the installation efficiency.

[0070] In large-scale prefabricated component assembly operations, such as batch construction of prefabricated houses or production line assembly of box-type truck carriages, this convenient installation process can significantly shorten the construction time, reduce labor costs, and improve production efficiency.

[0071] The connection groove 402 is connected with the first clamping part 401 and the third connecting part 3 connecting part 303. The design of the connection groove 402 has certain fault tolerance and self-adaptability to the installation precision. Even if there is a certain position deviation during installation, through the sliding and rotating adjustment of the fourth connecting part 4, each part can still be accurately clamped into the connection groove 402 to achieve good connection. This feature reduces the strict requirements on the operation precision of the installation workers and reduces the rework and adjustment work caused by installation errors.

[0072] Further, the elastic member 5 is arranged in the sliding groove 201, one end of the elastic member 5 acts on the bottom of the sliding groove 201, and the other end acts on the third connecting part 3 to provide the force for the third connecting part 3 to slide into the sliding groove 201.

[0073] In the embodiment, the elastic member 5 is arranged in the sliding groove 201 to provide the force for the third connecting part 3 to slide into the sliding groove 201. During the use of the prefabricated component, when subjected to external force interference or relative displacement between the connecting parts, the elastic member 5 can always keep the third connecting part 3 in a sliding trend into the sliding groove 201 to ensure the tightness of the connection with other connecting parts. For example, during the driving of the box truck, the vibration of the vehicle may cause the third connecting part 3 to have a tendency to slide outward. At this time, the force of the elastic member 5 can automatically reset it to the appropriate position to ensure the clamping with the fourth connecting part 4 and the stability in the sliding groove 201, thereby maintaining the stability of the entire prefabricated component structure, preventing the loosening of the connecting parts from affecting the overall performance of the vehicle compartment, and ensuring the safe transportation of goods.

[0074] For prefabricated houses, when subjected to external forces such as wind or slight earthquakes, the elastic member 5 can also play a similar role to keep the connection between the prefabricated components stable and enhance the overall seismic performance and structural reliability of the house.

[0075] During long-term use, the connecting parts may be deformed or displaced due to repeated stress. The continuous force of the elastic member 5 can effectively offset this trend, so that the third connecting part 3 is always in a good connection state. It can reduce the gap between the connecting parts, avoid the loosening caused by long-term wear or deformation, and prolong the service life of the prefabricated component. Whether in the frequent transportation task of the box truck or in the long-term use process of the prefabricated house, the elastic member 5 can provide strong guarantee for the durability of the connection and reduce the maintenance cost and replacement frequency.

[0076] Further, the first connecting part 1 has a connecting hole 108 for connecting other components in the vertical direction.

[0077] In this embodiment, the connection hole 108 on the first connecting piece 1 provides convenience for the connection of prefabricated components in the vertical direction with other components. In the design of the box truck compartment, different height compartment plates or frame structures can be connected vertically through the connection hole 108 to realize the layering or expansion of the compartment space. For example, when it is necessary to increase the storage space inside the compartment, a vertical partition or shelf can be installed using the connection hole 108 to flexibly adjust the layout inside the compartment and meet the loading needs of different goods.

[0078] For the construction of prefabricated houses, the connection hole 108 can reliably connect the wall components of different floors in the vertical direction. This not only helps to build multi-story building structures, but also provides more possibilities for the design and functional layout of the house. According to the living needs, the connection hole 108 can be used to connect vertical stairs, handrails and other auxiliary components to perfect the overall function of the house.

[0079] The presence of the connection hole 108 enables the prefabricated component to seamlessly connect with other components with corresponding connection structures, improving its versatility and compatibility in different building systems or industrial applications. Whether it is used in combination with other types of prefabricated components or connected with existing building structures or industrial equipment, the connection hole 108 provides a convenient interface.

[0080] In the field of construction, this versatility can promote the widespread use of prefabricated components in different building projects, reducing design and construction difficulties caused by incompatible components. In the industrial field, for example, when building temporary warehouses or industrial plants, prefabricated components can be combined with other industrial standard components through the connection hole 108 to quickly build structures that meet specific needs, improving construction efficiency and resource utilization.

[0081] Further, the first connecting piece 1 can be a right angle, a straight line or an angle.

[0082] In this embodiment, the right angle first connecting piece 1 can perfectly fit in the corners of the box truck compartment or the corners of the prefabricated house, providing stable connection. This shape makes it more convenient and efficient to build right angle structures without the need for complex angle adjustment or additional processing. For example, in the corners of the box truck compartment, the right angle first connecting piece 1 can ensure the tight connection between the side plate and the bottom plate, enhancing the overall stability of the compartment and preventing damage to the compartment structure when goods are stacked in the corners. In prefabricated houses, the right angle first connecting piece 1 can provide strong support for the corners, making the structure of the house more stable, and also facilitating the installation and layout of the wall.

[0083] The linear first connector 1 is suitable for scenarios that require long-distance connection, such as the long side of a box truck compartment or the long wall of a prefabricated house. It can quickly connect multiple identical or different components, achieving the extension and expansion of the structure. In a box truck compartment, the linear first connector 1 can be used to connect multiple side panels, increasing the length of the compartment to meet the transportation needs of different sizes of goods. In a prefabricated house, the linear first connector 1 can be used to build long walls, improving the overall stability and seismic performance of the house.

[0084] The angular first connector 1 has multiple angle options, which can meet the connection needs of different angles. For example, at the inclined parts of a box truck compartment or the sloping roof of a prefabricated house, the angular first connector 1 can be adjusted according to the specific angle requirements, achieving personalized structural design. In some special architectural designs, the angular first connector 1 can also be used to create unique spatial effects, increasing the aesthetic and artistic nature of the building.

[0085] Different shapes of the first connector 1 can be used in combination, providing more design possibilities for designers. In the design of a box truck compartment, the right-angle, linear, or angular first connector 1 can be flexibly selected and combined according to the shape and size of the goods to optimize the space utilization inside the compartment. In the construction of a prefabricated house, designers can skillfully use different shapes of the first connector 1 according to the architectural style and functional requirements, creating a variety of architectural forms.

[0086] Because the first connector 1 has multiple shape options, it makes the prefabricated component better meet the customization needs of customers. Whether it is a special size box truck compartment or a personalized prefabricated house design, it can be achieved by selecting the appropriate shape of the first connector 1. This customized design not only improves the applicability and competitiveness of the product, but also provides customers with more satisfactory solutions.

[0087] Different shapes of the first connector 1 provide specific support for different structural parts. The right-angle first connector 1 provides strong support at the corners, the linear first connector 1 shares external forces in long-distance connections, and the angular first connector 1 plays a role in stabilizing the structure at special angle parts. These targeted supports make the entire prefabricated component structure more stable and better able to withstand various external forces.

[0088] Reasonable use of different shapes of the first connecting piece 1 can make the stress more evenly distributed in the structure. For example, in prefabricated houses, by using different shapes of the first connecting piece 1 in different parts, it can avoid stress concentration in a certain area, thereby reducing the risk of deformation and damage of the structure. In the box truck compartment, different shapes of the first connecting piece 1 can be arranged according to the weight distribution of the goods and the stress in the driving process, improving the overall strength and durability of the compartment.

[0089] Further, the fourth connecting piece 4 has a handle part 403.

[0090] In this embodiment, the handle part on the fourth connecting piece 4 provides a convenient holding point for the operator, so that the fourth connecting piece 4 can be easily operated when assembling and disassembling the prefabricated component. During installation, the operator can hold the handle part to accurately insert the fourth connecting piece 4 into the fixing ring 104 of the first connecting part 101, and perform sliding, rotating and other operations, so that the first clamping part 401 is accurately clamped with the first clamping groove 301 of the third connecting piece 3. The convenience of this manual operation greatly improves the installation efficiency and reduces the installation time and labor cost.
