Description

Technical Field

[0001] This utility model relates to the field of drawing equipment technology, and in particular to an engineering cost drawing equipment. Background Technology

[0002] Construction cost drafting is a crucial aspect of construction cost management. Traditional drafting methods rely heavily on manual drawing or general-purpose drafting software, which suffers from low efficiency, poor accuracy, and inconvenience in making modifications. With the development of information technology in the construction industry, the demand for specialized drafting equipment is increasing. However, most drafting equipment on the market is geared towards the design field, lacking specialized tools tailored to the characteristics of construction cost.

[0003] A search revealed Chinese Patent Publication No. CN213786046U, which discloses an engineering cost drawing device. This utility model includes: a fixed plate, with hollow rods fixed to the bottom of the fixed plate near both side edges; a base plate fixed between the front surfaces of the two hollow rods near the top edge; a hollow fixing rod fixed to the top of the base plate; and two springs fixed inside the hollow fixing rod near both side edges. This utility model uses a clamping plate to initially fix different base plates, and then tightens the fixing plate by turning the nut, greatly improving the practicality of the device. Pushing the connecting rod into the hollow rod reduces the size of the device, and then lifting the rubber pull rope allows for movement, making the device more convenient and easy to move, achieving the most satisfactory results for different users.

[0004] However, in practical use, there are also significant problems with folding and moving the drawing table. After the drawing work is completed, it is necessary to organize and store the drawing tools, drawings, and other items. However, fixed drawing tables often take up a lot of space and are difficult to fold up quickly and effectively. At the same time, if it is necessary to change work locations, moving the heavy drawing table is not only laborious but may also damage the equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an engineering cost drawing device, which aims to improve the problem that fixed drawing tables often occupy a lot of space and are difficult to fold up quickly and effectively.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an engineering cost drawing device, comprising a housing, a partition fixedly connected inside the housing, a lead screw rotatably connected inside the partition, a driving mechanism provided at the bottom end of the lead screw, a lifting bracket threadedly connected to the outer wall of the lead screw, a push block fixedly connected to the outer wall of the lifting bracket, a sliding component slidably connected to the outer wall of the lifting bracket, the outer wall of the lifting bracket being fixedly connected to the inside of the housing, a rotating shaft being provided inside the housing, a torsion spring being provided on the outer wall of the rotating shaft, one end of the torsion spring being located inside the housing, and a top plate being fixedly connected to the other end of the torsion spring, the lower surface of the top plate being attached to the upper surface of the housing, a connecting rod rotatably connected to the lower surface of the top plate, a sliding frame rotatably connected to the outer wall of the connecting rod, the outer wall of the sliding frame being slidably connected to the inside of the housing, and a moving component being provided on the lower surface of the housing.

[0007] The above technical solution provides protection by using a drive mechanism to rotate a lead screw, which in turn raises and lowers the lifting bracket, thus changing the drawing height. When the equipment is retracted, the lifting bracket can be lowered, and the lifting bracket pushes the sliding frame to slide via a push block. The sliding frame pulls the top plate to rotate via a connecting rod. After the lifting bracket is retracted into the housing, the top plate can be closed. When the lifting bracket rises, a torsion spring opens the top plate, making it easy to retract the equipment and move it.
