Detachable office table for engineering cost

Abstract

This utility model relates to the field of engineering cost estimation, and in particular to a detachable desk for engineering cost estimation, including a tabletop. An installation assembly is mounted on the bottom of the tabletop, and a reinforcing shell is mounted on the surface of the installation assembly. A reinforcing rod is provided inside the cavity of the reinforcing shell. This utility model utilizes a support shell, positioning strip, positioning block, pull rod, support frame, connecting spring, and moving plate to achieve the advantage of detachability. By pulling the pull rod, the moving plate compresses the connecting spring, causing the connecting spring to contract, thus allowing the pull rod to move out of the positioning block and no longer fix it. Pulling the tabletop upwards allows the positioning block to move out of the support shell, thereby disassembling the tabletop for easy handling and improved transport convenience. Furthermore, the use of a male magnet, placement plate, rotating plate, short rod, positioning bolt, female magnet, and connecting nut facilitates the placement and viewing of drawings.

Technical Field

[0001] This utility model relates to the field of engineering cost technology, specifically a detachable desk for engineering cost estimation. Background Technology

[0002] Construction cost refers to the total cost incurred throughout the entire construction and building process of a project. It includes investment estimates, design estimates, revised estimates, construction drawing budgets, project settlement, and final settlement. It helps project managers understand the project's costs and make reasonable decisions. A desk is needed in construction cost estimation.

[0003] A search revealed that the patent number CN214855131U, entitled "Utility Model of an Office Desk for Engineering Cost Management," includes a desktop. Research and analysis revealed that while it avoids excessive height adjustment and improves the practicality of the device, it also has the following drawbacks to some extent.

[0004] For example, because it is not detachable during use, it is inconvenient to disassemble and move it later, increasing the difficulty of transportation. Moreover, it does not have a convenient function for placing and viewing drawings. Therefore, when it is necessary to place and view the drawings, they can only be placed on the desktop, occupying desktop space, and the staff have to look down to view them, reducing viewing comfort. In order to solve the above technical problems, we have designed a detachable desk for engineering cost estimation. Utility Model Content
