[0002] In outdoor work fields such as engineering cost estimation, engineering surveying, and construction site management, professionals need to carry and frequently use various surveying tools, calculators, drawings, and documents. Traditionally, workers typically use general-purpose toolboxes or tool bags to store these items. However, these conventional toolboxes are limited in function, only solving the problems of tool storage and transportation, and cannot meet the further needs of on-site work. Existing engineering cost estimation toolboxes still suffer from problems such as inconvenience in carrying them, inability to quickly retrieve and place tools, and inability to form a stable surveying platform.

[0003] Therefore, it is essential to invent a portable toolbox for engineering cost estimation. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a portable engineering cost estimation toolbox, solving the issues that existing engineering cost estimation toolboxes still suffer from being inconvenient to carry, unable to quickly retrieve and store tools, and unable to form a stable surveying platform. A portable engineering cost estimation toolbox includes a first box body, a second box body, protective edges, auxiliary plates, buckles, and a portable handle. The first and second box bodies are rotatably connected by hinges, and the protective edges are respectively fixedly installed on the outer sides of the first and second box bodies. The auxiliary plates are respectively snapped into the interiors of the first and second box bodies. The buckles are fixedly installed on the outer side of the second box body, and the portable handle is fixedly installed on the outer sides of both the first and second box bodies.

[0005] The first housing includes a housing shell, a protective bottom patch, a sliding compartment, a support rod, and a stabilizing foot. The protective bottom patch is fixedly installed on the bottom surface of the housing shell, and the sliding compartment is fixedly installed at two corners of the housing shell away from the hinge. The support rod is threaded into the interior of the sliding compartment, and the stabilizing foot is fixedly installed at the bottom of the support rod.

[0006] The auxiliary plate includes a base plate surface, positioning buckles, and pick-and-place holes. The positioning buckles are located on the outer side of the base plate surface and engage with the interior of the first and second housings. The pick-and-place holes are located on the surface of the base plate surface.

[0007] The internal structure of the first housing is completely identical to that of the second housing, and the first housing and the second housing can be opened and closed by hinges and by buckles; after the first housing and the second housing are opened by hinges, they can form a plane to support the surveying instrument, and are connected together by buckles at the rear ends of the first housing and the second housing; the support rod and the stabilizing foot can be extended and retracted to adapt to different terrains.

[0008] The auxiliary plate is made of two sets of stainless steel metal plates and can enclose the first box and the second box. After the first box and the second box are unfolded, the auxiliary plate forms a platform to support the surveying instrument. The auxiliary plate can be taken out through the pick-up and put-out hole and expose the items inside the first box and the second box.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The first box of this utility model is designed to be closed with the second box by snaps when carried, and to form a closed storage space by using the internal auxiliary plate and its positioning buckles. At the same time, the protective bottom patch of the outer shell of the box provides wear-resistant protection, and the portable handle on the outside is used for carrying. When in working condition, the first box and the second box are unfolded, and the upper surface of the outer shell of the box becomes part of the support platform. The adjustable support leg system composed of the sliding compartment, support rod and stabilizing feet at the bottom adapts to the terrain and ensures the stability of the entire platform.

[0010] 2. The auxiliary plate of this utility model is designed such that when the first and second boxes are in a closed carrying state, the auxiliary plate is respectively engaged inside the first and second boxes by its positioning buckles, with its base plate surface serving as an inner cover to seal and protect the items stored inside the outer shell of the boxes. When the first and second boxes are unfolded into a working platform by hinges, the user can easily remove the auxiliary plate through the access hole and place it on the outer shell of the unfolded first and second boxes. At this time, the base plate surfaces of the two auxiliary plates together form a complete, flat and stable platform for accurately supporting surveying instruments. At the same time, removing the auxiliary plate also fully exposes the tools stored inside the first and second boxes, making them easy to access directly. Attached Figure Description
