Description

Technical Field

[0001] This utility model belongs to the field of modular building, and specifically relates to a pull-out building. Background Technology

[0002] Pull-out structures are increasingly used in daily life due to their ease of transportation and ability to be used individually or in combination. While there are many types of pull-out structures on the market, most use container-like pull-out boxes, assembled in a nesting-doll style. During assembly, other pull-out boxes are pulled out and installed from a fixed main box that serves as the building's core. These pull-out boxes typically come in two types: with a bottom and without a bottom.

[0003] When using a bottomless pull-out box, the side wall of the fixed box serves as the base when pulling it outwards. This method has the following characteristics: 1. Because the side wall of the fixed box is used as the base, the depth of the pull-out box is limited by the height of the fixed box; 2. There is usually a gap between the slide rail at the bottom of the pull-out box and the rollers installed on the fixed box, which requires secondary finishing to seal the gap to ensure that the pull-out box can slide out smoothly; 3. Side wall bases are mostly single boxes with single pull-outs, and the facade structure of buildings is mostly square boxes, resulting in a lack of structural variety; 4. The pull-out box is installed in the fixed box through a sliding structure formed by the slide rail and rollers. The pull-out box and the fixed box structure are detached and have no direct connection. The overall structural support of the pull-out box relies entirely on the bottom slide rail, which may result in insufficient structural stability.

[0004] When using pull-out boxes with bottoms, the boxes are generally assembled on-site using sliding rails. This method has the following characteristics: 1. The sliding rails inside the fixed box are not the same as the extended sliding rails installed on-site, requiring the rails to be positioned first during installation; 2. The pull-out box is installed inside the fixed box through a sliding structure formed by the sliding rails and rollers. The pull-out box is detached from the fixed box structure and has no direct connection. The overall structural support of the pull-out box relies entirely on the bottom sliding rails, which may result in insufficient structural stability; 3. Pull-out boxes are generally single-box structures, and the facade structure of buildings is mostly square, leading to a lack of structural variety. Summary of the Invention

[0005] To address the aforementioned problems, the primary objective of this utility model is to provide a pull-out building that allows for convenient and reasonable adjustment of the building's dimensions and height based on the spatial layout.

[0006] Another objective of this invention is to provide a pull-out building that is easier and faster to install and allows for more diverse installation methods.

[0007] Another objective of this invention is to provide a pull-out building with a more stable overall structure.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] This utility model provides a pull-out building, including:

[0010] Fixed box, including one or more pull-out spaces;

[0011] One or more pull-out boxes, each of which is movably arranged in one or more pull-out spaces;

[0012] The bottom of the pull-out space is provided with a slide rail, and the bottom of the pull-out box is provided with a support beam. One end of the support beam is provided with an inner roller, which is slidably connected to the slide rail. The bottom of the outlet of the pull-out space is also provided with a fixed pulley, which is supported on the bottom of the support beam and can slide relative to the support beam.

[0013] Furthermore, an outer roller is provided at the other end of the supporting bottom beam. The outer roller is located outside the pull-out space, and the bottom of the outer roller is level with the bottom of the fixed box.

[0014] Furthermore, the slide rail, fixed pulley, supporting bottom beam, inner roller, and outer roller are all on the same vertical plane.

[0015] Furthermore, the fixed box, slide rail, and fixed pulley are integrally formed, and the three are prefabricated as a whole at the factory.

[0016] Furthermore, the pull-out box is also equipped with a locking component. The fixed box is fixedly connected to the pull-out box through the locking component. The pull-out box and the locking component are prefabricated as one piece at the factory. After the pull-out box is unfolded and pulled out, the fixed box and the pull-out box can be locked together by the locking component to ensure the structural stability of the two.

[0017] Furthermore, the locking element includes a connection to the fixed housing via a screw.

[0018] Furthermore, the top of the fixed box and the pull-out box has an arc-shaped sloping structure.

[0019] The superior effect of this utility model is that, compared with the technology:

[0020] First, the pull-out box of this application does not need to rely on the side wall of the fixed box as its base, and the pull-out box does not depend on the size of the fixed box, which can conveniently adjust the size and height of the building according to the layout of the building space.

[0021] Secondly, the inner rollers of the pull-out box can slide on the slide rail, and the outer rollers can slide on the ground. Without the need for secondary installation of guide rails on site, the pull-out box can be stably pulled out, making the installation of pull-out buildings more convenient and faster. The pull-out box can be pushed out and fixed and then hoisted together with the fixed box, or it can be pushed out and pulled out after hoisting, making the installation methods more diverse.

[0022] Furthermore, during the pulling-out process, the pull-out box can utilize fixed pulleys to support the bottom beam of the pull-out box, making the overall structure more stable;

[0023] Finally, the top of the fixed box and the pull-out box in this application can be set as an arc-shaped sloping structure, which changes the original single shape and makes it more aesthetically pleasing. Attached Figure Description
