[0002] When it comes to budgeting for interior renovations or furniture purchases, it's often necessary to bring paper, pen, and other tools to conduct on-site surveys and measurements, and record accurate data. Since the house is not yet furnished, there is no place for users to place paper and pen. Some simple data can be recorded by holding a pen in one hand and paper in the other, but it becomes inconvenient when drawing or using drawing tools such as rulers.

[0003] According to CN215076199U, a construction cost estimation device based on house area is disclosed, including a base with fixing devices on both sides. A groove is opened in the middle of the top surface of the base, and a lifting device is connected in the groove. The lifting device can be locked after rotating at any angle in the groove. A support plate is provided at the upper end of the movable part of the lifting device. There are mounting plates on the left and right side walls of the base, and connecting rods are connected between the mounting plates. The outer side of the connecting rods is connected to a suction cup through a limiting rotation structure. This device fixes the base to the wall or ground through the fixing devices. Paper, pens, drawing tools, etc. can be placed on the support plate or the base. When writing or drawing is needed, the user can rotate the support plate to face different places in the room for drawing or recording data. When rotation is not needed, the support plate can be fixed by the suction cup. At the same time, the lifting device can adjust the height of the support plate to adapt to different situations and reduce the discomfort caused to the user when writing or drawing.

[0004] In the above scheme, the overall structure composed of the lifting device is not easy to carry and use, and the overall usage mode is limited, which cannot meet the actual needs of the structure. Utility Model Content

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0035] For ease of description, this utility model is described in detail. Figure 1 and Figure 2 The central axis is depicted as a double-dotted line.

[0036] Example 1:

[0037] refer to Figures 1-4 A construction cost budgeting device based on building area includes a main board 10, a first sub-board 20, and a second sub-board 30.

[0038] The main board 10, the first sub-board 20, and the second sub-board 30 are assembled together;

[0039] The motherboard 10 is an isosceles right triangle;

[0040] The motherboard 10 is symmetrically cut along a double-dotted line in the center, which equals the first sub-board 20 and the second sub-board 30.

[0041] The motherboard 10 has symmetrical extension heads 103 and extension slots 104 on both isosceles sides. The first sub-board 20 and the second sub-board 30 are also provided with extension heads 103 and extension slots 104 at the corresponding parts of the motherboard 10 on both isosceles sides. The first sub-board 20 and the second sub-board 30 are respectively spliced ​​on the motherboard 10 on both isosceles sides.

[0042] In the above scheme, the extension slot 104 of the first sub-board 20 and the extension head 103 of the second sub-board 30 are respectively spliced ​​on the extension head 103 and extension slot 104 on both sides of the isosceles of the main board 10, that is, the first sub-board 20 and the second sub-board 30 are respectively spliced ​​on both sides of the isosceles of the main board 10.

[0043] During use, Figure 2 To use the state diagram, the drawing is placed on the surface of three boards (main board 10, first sub-board 20 and second sub-board 30) for drawing or recording data, reducing the discomfort caused to the user when writing and drawing.

[0044] In the preferred configuration, the first sub-board 20 and the second sub-board 30 are respectively spliced ​​onto the two isosceles sides of the main board 10 to form a rectangle. The rectangle increases the overall area, making it easier for staff to lay out larger sheets of paper, thus providing them with more drawing space. It should be noted that the rectangle here is a long rectangle.

[0045] Example 2:

[0046] refer to Figure 5 The main board 10 has several first magnetic grooves 101 on one side, and the first sub-board 20 and the second sub-board 30 have adsorption heads 205 at the corners of their surfaces. The adsorption heads 205 are attracted to the first magnetic grooves 101.

[0047] The first sub-board 20 and the second sub-board 30 are both mounted on the surface of the main board 10 to form an isosceles right triangle;

[0048] In the above scheme, the first sub-board 20 and the second sub-board 30 are symmetrically flipped on both sides of the main board 10 isosceles, forming Figure 5 The diagram shows the usage status of the components. The splicing combination between them is attracted to each other by the adsorption head 205 and the first magnetic groove 101, thereby preventing the first sub-board 20 and the second sub-board 30 from detaching from the surface of the main board 10.

[0049] In this embodiment, the main board 10, the first sub-board 20, and the second sub-board 30 form an isosceles right triangle for carrying and use. This shape also makes it convenient for users to test the right angle of a corner. In specific use, simply place the right-angled side at the corner position.

[0050] Example 3:

[0051] refer to Figure 6 The first sub-board 20 and the second sub-board 30 are combined and spliced ​​together.

[0052] The extension groove 104 of the first sub-plate 20 and the extension head 103 of the second sub-plate 30 cooperate with each other.

[0053] The first sub-board 20 and the second sub-board 30 are combined and spliced ​​to form a square;

[0054] In the above scheme, the combined use of the first sub-board 20 and the second sub-board 30 allows the main board 10 to be separated. In this way, the surfaces of the first sub-board 20 and the second sub-board 30 can be used to place paper for drawing, and the isosceles right-angled triangle main board 10 can be used for independent measurement.

[0055] Further reference Figures 7-9 The first sub-plate 20 and the second sub-plate 30 are both provided with a second magnetic groove 201, and a corner leg 204 is fitted inside the second magnetic groove 201.

[0056] In a further embodiment, the first sub-plate 20 and the second sub-plate 30, which are easily combined using corner legs 204, are supported on the ground for use.

[0057] Reference in the preferred solution Figure 8 and Figure 9 The first sub-plate 20 and the second sub-plate 30 are both provided with a recessed groove 202 near the second magnetic groove 201. The recessed groove 202 is hinged to an L-shaped support angle 203, which is used to support the corner leg 204.

[0058] In a preferred embodiment, when the combination of the first sub-plate 20 and the second sub-plate 30 is supported by the corner leg 204, the support corner 203 is first rotated out and removed from the sinking groove 202. The bend of the support corner 203 is supported at the corner of the corner leg 204, which can improve the support stability of the corner leg 204.

[0059] Example 4:

[0060] refer to Figure 10 The motherboard 10 has symmetrically arranged mounting slots 102 on opposite sides, and the mounting slots 102 cooperate with the corner legs 204.

[0061] In the above solution, based on Embodiment 2, when the main board 10, the first sub-board 20, and the second sub-board 30 form an isosceles right triangle, the corner leg 204 can be removed from the second magnetic groove 201 and placed in the assembly groove 102. The assembly groove 102 can completely enclose the corner leg 204 without affecting the assembly between the three boards. The assembly groove 102 and the corner leg 204 are magnetically engaged.

[0062] Example 5:

[0063] refer to Figure 3 The main board 10 has scale bars 40 on its isosceles opposite side surface, and the first sub-board 20 and the second sub-board 30 also have scale bars 40 on both sides. The scale bars 40 are used to facilitate surveying.

[0064] Here, the mainboard 10, the first sub-board 20, and the second sub-board 30 can all be regarded as independent entities and can be used separately.

[0065] In summary, it should be noted that the first sub-plate 20 and the second sub-plate 30 of the present invention are identical in all positions except for the extension head 103 and the extension groove 104. The magnetic attraction method improved in this invention refers to the ability of one object to be attracted by the other, which can be summarized as the mutual attraction mode between a magnet and iron. Specifically, this can be manifested as a magnet fixed inside the groove, and the other object being a metal that can be attracted by the magnet, or having a surface covered with metal.

[0066] The specific implementation process of this utility model is as follows:

[0067] Method 1: The extension slot 104 of the first sub-board 20 and the extension head 103 of the second sub-board 30 are respectively spliced ​​on the extension head 103 and extension slot 104 on the two isosceles sides of the main board 10, that is, the first sub-board 20 and the second sub-board 30 are respectively spliced ​​on the two isosceles sides of the main board 10 to form a rectangle.

[0068] Method 2: The first sub-board 20 and the second sub-board 30 are both mounted on the surface of the main board 10 to form an isosceles right triangle; the splicing combination between them is mutually attracted to the first magnetic groove 101 by the adsorption head 205;

[0069] Method 3: The first sub-board 20 and the second sub-board 30 are combined to form a square, which allows the main board 10 to be separated. In this way, the surfaces of the first sub-board 20 and the second sub-board 30 can be used to place paper for drawing, and the isosceles right-angled triangle main board 10 can be used for independent measurement.
