Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated cabin technology, and in particular to a modular prefabricated cabin. Background Technology
[0002] Modular prefabricated modules refer to prefabricated building units designed, manufactured, and assembled according to specific standardized modules (i.e., "modules"). These prefabricated modules are generally composed of multiple standardized components that can be flexibly spliced, combined, or disassembled to meet different uses, structural, and dimensional requirements. Modular prefabricated modules are commonly used in warehousing, temporary housing, office spaces, and sanitation facilities.
[0003] When assembling existing prefabricated modules, different wall panels are usually spliced together at predetermined positions. However, since existing wall panels are usually manufactured according to standardized dimensions and production processes, the splicing spacing is usually fixed. Wall panels with fixed spacing cannot adapt to the needs of different sites, especially in irregular building environments, which may lead to construction errors and unsuitable structures.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0026] Example 1:
[0027] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a modular prefabricated cabin, including an adjustment mechanism 6. First, when the user splices the prefabricated wall panel 1 with the retractable shell 2, and needs to fine-tune the distance between the prefabricated wall panel 1 and other wall panels, the user first pulls the pull ring 612 to make the pull rod 611 drive the positioning ring 610 to squeeze the spring 613. Then, the insertion rod 609 disengages from the limiting groove 603 on the gear 602. Then, the lever is inserted through the groove 614, and the rotating rod 601 drives the gear 602 to rotate. At this time, the toothed plate 604 will drive the retractable shell 2 to move relative to each other. When the toothed plate 604 moves, it will drive the sliding plate 605 to move on the surface of the limiting rod 606 to improve the stability of the toothed plate 604 when it moves. After the adjustment is completed, the pull ring 612 is loosened, and the spring 613 drives the positioning ring 610 to reset the insertion rod 609 and insert it into the limiting groove 603.
[0028] A retractable shell 2 is provided on one side of the precast wall panel 1. Slots 3 are provided on both the front and rear sides of the precast wall panel 1. Connecting grooves 4 are provided on the top and bottom of both sides of the precast wall panel 1. A limit frame 5 is fixedly connected inside the retractable shell 2. An adjustment mechanism 6 is provided inside the limit frame 5.
[0029] Firstly, the retractable shell 2 facilitates the splicing of two prefabricated wall panels 1 on both sides of the retractable shell 2. The retractable shell 2 has a certain degree of retraction on both sides, and the slots 3 and connecting grooves 4 facilitate the positioning of the prefabricated wall panels 1.
[0030] The adjustment mechanism 6 includes a rotating rod 601, a gear 602, and a limiting groove 603. The rotating rod 601 is rotatably connected to the inside of the limiting frame 5. The gear 602 is fixed to the surface of the rotating rod 601. The limiting groove 603 is arranged in a ring array inside the gear 602. The top and bottom of the gear 602 are respectively meshed with toothed plates 604. The opposite sides of the two toothed plates 604 are fixedly connected to the inner wall of the retractable shell 2. The opposite sides of the two toothed plates 604 are fixedly connected to sliding plates 605. The sliding plate 605 is slidably connected to a limiting rod 606. One end of the limiting rod 606 is fixedly connected to the inner wall of the retractable shell 2. One side of the limiting rod 606 is fixedly connected to a positioning plate 607. One side of the positioning plate 607 is fixedly connected to the limiting frame 5. One end of the rotating rod 601 extends to the outside of the retractable shell 2. A groove 614 is provided at one end of the rotating rod 601.
[0031] When the user splices the prefabricated wall panel 1 with the retractable shell 2, and needs to fine-tune the distance between the prefabricated wall panel 1 and other wall panels, a lever is inserted into the groove 614, and the rotating rod 601 drives the gear 602 to rotate. As the gear 602 rotates, the toothed plate 604 will drive the retractable shell 2 to move relative to it. When the toothed plate 604 moves, it will drive the sliding plate 605 to move in a limited position on the surface of the limiting rod 606, thereby improving the stability of the toothed plate 604 during movement and adjusting the prefabricated wall panel 1.
[0032] Example 2:
[0033] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0034] Specifically, a reinforcing block 608 is fixedly connected to one side of the toothed plate 604, and one side of the reinforcing block 608 is fixedly connected to the inner wall of the retractable shell 2.
[0035] By fixing the reinforcing block 608 to the retractable shell 2, the connection strength between the toothed plate 604 and the retractable shell 2 can be improved.
[0036] Specifically, a rod 609 is inserted into the inside of the limiting groove 603. A positioning ring 610 is fixedly connected to one side of the rod 609. A pull rod 611 is fixedly connected to one side of the positioning ring 610. One end of the pull rod 611 extends through to the outside of the retractable shell 2 and is fixedly connected to a pull ring 612. A spring 613 is fixedly connected between one side of the positioning ring 610 and the limiting frame 5.
[0037] By setting the insertion rod 609, pulling the pull ring 612 causes the pull rod 611 to drive the positioning ring 610 to squeeze the spring 613. Then the insertion rod 609 disengages from the limiting groove 603 on the gear 602, thereby facilitating the rotation of the gear 602. When it is necessary to limit the position of the adjusted gear 602, the pull ring 612 is loosened, and the spring 613 drives the positioning ring 610 to reset the insertion rod 609 and insert it into the limiting groove 603.
[0038] Specifically, a reinforcing plate 7 is fixedly connected to one side of the limiting frame 5, and one side of the reinforcing plate 7 is fixedly connected to the inner wall of the retractable shell 2.
[0039] By fixing the reinforcing plate 7 to the retractable shell 2, the connection strength between the limiting frame 5 and the retractable shell 2 can be improved.
[0040] Specifically, two retaining rods 8 are fixedly connected to the two sides inside the retractable shell 2, and retaining plates 9 are fixedly connected to opposite ends of the two retaining rods 8. One side of the retaining plate 9 is fixedly connected to the limiting frame 5, and a retaining bracket 10 is sleeved between the surfaces of the two retaining rods 8.
[0041] By fixing the retaining rod 8 to the retractable shell 2, when the retractable shell 2 moves and retracts, it will drive the retaining rod 8 to move relative to each other. In conjunction with the retaining frame 10, the stability between the two retaining rods 8 can be improved, so that the retaining rod 8 is limited to move relative to each other.
[0042] Specifically, both sides of the retractable shell 2 are fixedly connected with insert plates 11 for use with slots 3, the top and bottom of both sides of the retractable shell 2 are fixedly connected with insert blocks 12 for use with connecting grooves 4, both sides of the retractable shell 2 are fixedly connected with reinforcing ribs 13, and both sides of the precast wall panel 1 are provided with column grooves 14 for use with reinforcing ribs 13.
[0043] The insert plate 11 is conveniently inserted into the slot 3, and the insert block 12 is inserted into the connecting groove 4, which facilitates the assembly and fixing between the prefabricated wall panel 1 and the retractable shell 2. The setting of the reinforcing rib 13 and the column groove 14 can improve the strength of the lateral installation of the prefabricated wall panel 1 and the retractable shell 2.
[0044] In use, firstly, the slot 3 of the precast wall panel 1 is aligned with the insert plate 11 and the insert block 12 is aligned with the connecting groove 4 and inserted, and then fixed with screws. At this time, the reinforcing rib 13 is inserted into the column groove 14 on the precast wall panel 1, thereby improving the strength of the precast wall panel 1. After the precast wall panels 1 on both sides of the retractable shell 2 are installed, the distance between the precast wall panels 1 and the wall panels needs to be adjusted to facilitate replacement. During assembly, the pull ring 612 can be pulled to make the pull rod 611 drive the positioning ring 610 to squeeze the spring 613. Then, the insert rod 609 disengages from the limiting groove 603 on the gear 602, and then inserts the lever through the groove 614, causing the rotating rod 601 to drive the gear 602 to rotate. The rotating toothed plate 604 of 602 will drive the retractable shell 2 to move relative to each other. When the toothed plate 604 moves, it will drive the sliding plate 605 to move relative to the surface of the limiting rod 606, thereby improving the stability of the toothed plate 604 during movement and adjusting the precast wall panel 1. At the same time, through the fixation of the retaining rod 8 to the retractable shell 2, when the retractable shell 2 moves relative to each other and retracts, it will drive the retaining rod 8 to move relative to each other. In conjunction with the retaining frame 10, it can improve the stability between the two retaining rods 8 and limit the relative movement of the retaining rod 8. Then, the pull ring 612 is loosened, and the spring 613 drives the positioning ring 610 to reset the insertion rod 609 and insert it into the limiting groove 603, thereby positioning the adjusted position.
