Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost display, in particular to an engineering cost display tool. Background Art

[0002] Project cost, as a core indicator for measuring the economic feasibility of a project, covers the total amount of all anticipated or actual expenses from project planning to final acceptance. From the investor's perspective, project cost is directly equivalent to construction cost, i.e., the total fixed asset investment planned or actually invested to complete a project. Its core task is to accurately calculate all costs included in the project based on design drawings, quota standards, and list specifications to ensure the accuracy and effectiveness of investment control.

[0003] In the practice of engineering cost analysis, drawings serve as a bridge between design and construction, and their importance is self-evident. However, traditional drawing display methods have many inconveniences. Common drawing display racks on the market often include a display board that is larger than the drawing itself. When using it, workers lay the drawings flat on the display board for viewing. While this display method is intuitive, its portability is greatly reduced due to the large size and fixed nature of the display board. Therefore, we have sought to improve this by proposing a tool for displaying engineering cost. Summary of the Invention

[0034] It should be noted that the embodiments in the present application and the features and technical schemes in the embodiments can be combined with each other without conflict.

[0035] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0036] Embodiment 1, please refer to Figure 1-Figure 2 The engineering cost display tool has the advantages that the rotatable connecting pieces are rotatably arranged between the first support frames 2 and the display board body 208, and the rotatable connecting pieces are liftably arranged between the first support frames 2 and the display board body 208, the engineering cost display tool is folded and stored when not in use, the overall volume is greatly reduced, and the portability of the tool is greatly improved.

[0037] Further, as Figure 1 and Figure 2As shown, a gripping rod 203 is fixedly connected between the two second support frames 202. The gripping rod 203 connects the two second support frames 202 together to improve the overall stability. The gripping rod 203 can also be folded for the user to hold when carrying.

[0038] Example 2 further optimizes the engineering cost display tool provided in Example 1. Specifically, a limiting member is set between the display board body 208 and the second support frame 202. The limiting member is used to limit the position of the display board body 208, so as to fix the position of the display board body 208 after adjusting the height of the display board body 208.

[0039] Further, such as Figure 1-Figure 2 As shown, the limiting member includes a plurality of third limiting holes 209 provided on the display board body 208, and a third hand-tightening bolt 210 is provided on the second support frame 202. One end of the third hand-tightening bolt 210 is plugged into one of the third limiting holes 209. The position of the display board body 208 is fixed by the mutual cooperation between the third hand-tightening bolt 210 and the third limiting hole 209. After the third hand-tightening bolt 210 is rotated to separate the third hand-tightening bolt 210 from the third limiting hole 209, the display board body 208 can be pulled to adjust the position of the display board body 208. A notch is provided on the side of the first support frame 2 close to the support structure 1, and the notch is used to avoid the third hand-tightening bolt 210 in the folded state.

[0040] Further, such as Figure 1-Figure 2 As shown, the two second support frames 202 are fixedly connected to a connecting shaft 201 on one side away from each other, and the ends of the two connecting shafts 201 away from each other pass through the two first support frames 2 respectively. The connection between the second support frame 202 and the first support frame 2 can be achieved through the connecting shaft 201, and the second support frame 202 can be rotated.

[0041] Further, such as Figure 1-Figure 2 As shown, two second limiting holes 205 are provided on the connecting shaft 201, respectively located on both sides of the connecting shaft 201, and a first limiting hole 204 is provided on the second support frame 202. A second hand-tightening bolt 206 is connected between the first limiting hole 204 and one of the second limiting holes 205. The position of the second support frame 202 can be fixed by the mutual cooperation between the second hand-tightening bolt 206 and the first limiting hole 204.

[0042] Example 3 further optimizes the project cost display tool provided in Example 1 or 2. Specifically, Figure 1-Figure 3 As shown, the support structure 1 includes a first support plate 101 , the top of the first support plate 101 is fixedly connected to the bottom of the two first support frames 2 , and the two first support frames 2 can be supported by the support structure 1 .

[0043] Further, such as Figure 3 As shown, a limiting groove 103 is provided at the bottom of the first support plate 101 , and a second support plate 106 is inserted into the limiting groove 103 . The second support plate 106 can improve the stability of the first support plate 101 .

[0044] Further, such as Figure 1 and Figure 2 As shown, a groove 104 is provided on the top of the first support plate 101, and a first hand-tightening bolt 105 is threadedly connected between the first support plate 101 and the second support plate 106. The position of the first hand-tightening bolt 105 corresponds to the position of the groove 104. The second support plate 106 and the first support plate 101 can be connected together through the first hand-tightening bolt 105. The setting of the groove 104 prevents the top of the first hand-tightening bolt 105 from protruding.

[0045] Further, such as Figure 3 As shown, a receiving groove 102 is further provided at the bottom of the first support plate 101 . The size of the receiving groove 102 matches the size of the second support plate 106 , so that the second support plate 106 can be received in the receiving groove 102 after being folded as a whole.

[0046] The usage process of the engineering cost display tool provided by this utility model is as follows:

[0047] Reference Figure 1 When in use, the drawing paper is attached to the display board body 208 for display. After use, the third hand-tightening bolt 210 is screwed to separate the third hand-tightening bolt 210 from the third limiting hole 209, and the display board body 208 is pushed downward to the lowest point. The third hand-tightening bolt 210 is screwed, and the first hand-tightening bolt 105 is rotated to separate the first hand-tightening bolt 105 from the second support plate 106. The second support plate 106 is placed in the storage groove 102 and then connected by the first hand-tightening bolt 105. The second hand-tightening bolt 206 is loosened to separate the second hand-tightening bolt 206 from the first limiting hole 204 and the second limiting hole 205. The second support frame 202 is rotated downward with the connecting shaft 201 as the center, and then the second hand-tightening bolt 206 is screwed. Figure 4 As shown, the overall volume is reduced, so that it is easy to carry, and the gripping rod 203 can be held for hand-carrying;

[0048] When using again, unscrew the second hand-tightening bolt 206, rotate the second support frame 202 upward, then screw on the second hand-tightening bolt 206, rotate the first hand-tightening bolt 105 to separate the first hand-tightening bolt 105 from the second support plate 106, take the second support plate 106 out of the storage slot 102, insert it into the limiting slot 103, and then fix it with the first hand-tightening bolt 105.
