[0002] Modular housing, as an important form of modern industrialized construction, achieves rapid construction through on-site assembly of prefabricated housing modules. Reliable connections between modules are the core link to ensure the structural safety of the building. In the construction process of modular housing, each prefabricated module, such as walls, roofs, and floors, needs to be precisely assembled through connecting components.

[0003] Existing traditional modular housing connections mostly use bolt fixing or welding processes. These methods are not only cumbersome and time-consuming to install, but also require high construction precision. They are also prone to damaging modules during disassembly, making it difficult to meet the needs of modern industrialized construction for rapid assembly and flexible disassembly. As a result, they are inefficient and have certain shortcomings. Utility Model Content

By setting a limiting component, it can achieve rapid limiting connection between the limiting shell and the square block, thereby enabling fixed connection between the left and right prefabricated modules. By setting an ejection component, it can achieve rapid disassembly between the limiting shell and the square block, thereby enabling rapid separation between the left and right prefabricated modules.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1 to 4 As shown, a quick-installation modular house locking connector includes a left prefabricated module 1 and a right prefabricated module 2. A left T-shaped block 3 is slidably connected to the inner wall of the left prefabricated module 1, and a right T-shaped block 4 is slidably connected to the inner wall of the right prefabricated module 2. The left T-shaped block 3 and the right T-shaped block 4 are designed with a T-shaped cross-section and slide in conjunction with the T-shaped groove on the inner wall of the prefabricated module, which facilitates horizontal fine-tuning when aligning the modules. The T-shaped structure can withstand a large horizontal shear force and improve the connection strength.

[0022] A limiting shell 6 is provided on the right side of the adjusting component 5, and a square block 8 is slidably connected to the inner wall of the limiting shell 6.

[0023] An adjustment component 5 is provided on the right side of the left T-shaped block 3.

[0024] The adjustment component 5 includes a storage cylinder 501 fixedly connected to the outer surface of the left T-shaped block 3. The storage cylinder 501 has a hollow cylindrical structure with a smooth inner wall to ensure smooth sliding of the screw 502. It can limit the screw 502 to ensure its stability during movement.

[0025] The end of the screw 502 away from the storage cylinder 501 is fixedly connected to the outer surface of the limiting shell 6. Its outer surface is connected to the inner wall of the rotating cylinder 503 by a thread. Rotating the rotating cylinder 503 can drive the screw 502 to extend and retract, thereby achieving precise adjustment of the spacing between the prefabricated modules. The self-locking characteristic of the thread can prevent displacement due to vibration after connection, ensuring structural stability.

[0026] The screw 502 is threadedly connected to a rotating cylinder 503 on its outer surface, and the inner wall of the rotating cylinder 503 is rotatably connected to the outer surface of the storage cylinder 501. The outer surface of the rotating cylinder 503 is provided with anti-slip protrusions, which can improve the comfort and anti-slip properties of the operator. By rotating the rotating cylinder 503, the screw 502 is gradually extended out of the storage cylinder 501. The distance between the storage cylinder 501 and the limiting shell 6 is adjusted to achieve pre-alignment.

[0027] The limiting shell 6 has a set of ejection components 7 inside.

[0028] The ejection assembly 7 includes a slide rod 701 that is slidably connected to the inner wall of the limiting shell 6. One end of the slide rod 701 is fixedly connected to a circular flat pressing plate 702. The pressing plate 702 can be made of rubber, which facilitates construction and operation and provides high comfort.

[0029] The other end of the slide rod 701 is fixedly connected to the top plate 703. The top plate 703 is made of stainless steel and the surface is polished to make the sliding between it and the inner wall of the limiting shell 6 smoother and avoid jamming.

[0030] An elastic element 704 is fitted onto the outer surface of the slide rod 701. Its two ends are fixed to the outer surfaces of the pressing plate 702 and the limiting shell 6, respectively. When the pressing plate 702 is pressed, the slide rod 701 drives the top plate 703 to push the limiting component 9, and the elastic element 704 is compressed and stores energy. After being released, the elastic element 704 resets, driving the ejection component 7 to quickly return to its original position, thus achieving convenient disassembly.

[0031] The interior of the square block 8 is equipped with a set of limiting components 9.

[0032] The limiting component 9 includes a slider 901 slidably connected to the inner wall of the square block 8. One end of the slider 901 is fixedly connected to the wedge-shaped insert 902, and the other end is fixed to the elastic element 903. The other end of the elastic element 903 is fixed to the inner wall of the square block 8. When the square block 8 is inserted into the limiting shell 6, the insert 902 is squeezed by the inclined surface of the inner wall of the limiting shell 6, which drives the slider 901 to compress the elastic element 903. When it reaches the slot position, the elastic element 903 resets and pushes the insert 902 into the slot to achieve automatic locking. The self-locking effect of the wedge structure can enhance the connection reliability, and the elastic element 903 can buffer the small displacement of the module and avoid rigid damage.

[0033] Working principle: When connecting the left prefabricated module 1 and the right prefabricated module 2, push the left T-block 3 and the right T-block 4 closer together. The screw 502 in the adjusting assembly 5 is threaded into the rotating cylinder 503, allowing the rotating cylinder 503 to rotate. This gradually extends the screw 502 from the receiving cylinder 501, adjusting the distance between the receiving cylinder 501 and the limiting shell 6 to achieve pre-alignment. After alignment, the square block 8 is inserted into the limiting shell 6. The sliding piece 901 and the insert 902 slide into the square block 8 due to the pressure of the inner wall of the limiting shell 6 on the inclined surface of the insert 902. The sliding piece 901 compresses the elastic element 903. When the square block 8 is fully inserted into the limiting shell 6, the insert 902 also slides to the slot position inside the limiting shell 6. The elastic element 903 resets, pushing the insert 902 into the slot, completing the locking. During disassembly, pressing the pressing plate 702 of the ejector component 7 causes the sliding rod 701 to slide close to the insert block 902. The sliding rod 701 will cause the top plate 703 to move accordingly and push the insert block 902 into the square block 8. The insert block 902 will overcome the elastic force of the second elastic element 903 and push the insert block 902 out of the slot of the limiting shell 6, so that it returns to the square block 8. At this time, the square block 8 can be easily pulled out from the limiting shell 6, realizing module separation. At the same time, the first elastic element 704 is compressed and stores energy. When the pressing plate 702 is released, the first elastic element 704 will push the pressing plate 702, the sliding rod 701 and the top plate 703 to move quickly in the opposite direction, realizing quick reset and facilitating the normal operation of the next disassembly. The whole process realizes the functions of quick locking and convenient disassembly through mechanical linkage and elastic element cooperation.
