Description

Technical Field

[0001] This utility model relates to the field of engineering cost technology, and in particular to a portable cost auditing instrument. Background Technology

[0002] Construction cost refers to all expenses incurred in carrying out a construction project. The construction budget is particularly important for the smooth progress of the entire construction plan. In the process of construction cost estimation, it is usually necessary to use a calculation board to calculate and display the costs.

[0003] Currently, the cost calculation board is bulky and inconvenient to carry. It cannot be folded to reduce its overall length, which can lead to damage during transportation, causing the board to bend and affecting its performance in later use.

[0004] Therefore, this utility model proposes a portable cost auditing instrument. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a portable cost auditing device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a portable cost auditing instrument, comprising:

[0007] The calculation board assembly consists of two boards. Each of the two boards has a snap-fit ​​groove at one end that is close to the other. A reserved groove is provided on the side of the two snap-fit ​​grooves that is away from the snap-fit ​​grooves. A limit protrusion is provided on the reserved groove.

[0008] The connecting folding assembly consists of a connecting plate and a connecting seat that are slidably connected to the limiting protrusion. There are two connecting plates, and each connecting plate is connected to a corresponding plate body. The ends of the two connecting plates that are close to each other are rotatably connected to the connecting seat.

[0009] Furthermore, the pressure strip assembly consists of a sliding snap-fit ​​seat, an elastic rope, and a pressure strip disposed inside the snap-fit ​​groove. The two ends of the pressure strip are connected to the two sliding snap-fit ​​seats via the elastic rope.

[0010] The beneficial effects of adopting the above-mentioned further solution are: under the action of the pressure strip assembly, when using the calculation board assembly later, the drawing can be fixed on the board body through the pressure strip assembly. By attaching the drawing to the surface of the board body through the pressure strip, it is convenient to unfold the drawing for calculation. Furthermore, under the action of the elastic rope, tension is applied to the pressure strip to prevent the drawing from separating from the elastic rope through the gap.

[0011] Furthermore, a limiting groove is provided on the snap-fit ​​groove, and a protrusion is provided on the sliding snap-fit ​​base that penetrates the limiting groove. The sliding snap-fit ​​base is slidably connected to the limiting groove through the protrusion.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the protrusion is limited by the limiting groove, which prevents the protrusion from separating from the plate during the use of the quota, causing the drawing to lose downward pressure and fall. In addition, the limiting groove is a strip structure, and the pressure strip assembly can be slid to a suitable position to fix the drawing as needed during use.

[0013] Furthermore, the connecting plate is provided with a limiting bolt that penetrates through the connecting plate and connects to the plate body.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the limiting bolt, the connecting plate and the plate body are limited and fixed, avoiding gaps between the two plates after they are connected, which would affect the normal use of the calculation board.

[0015] Furthermore, limiting grooves are provided on both sides of the connecting plate, and the connecting plate is slidably connected between the corresponding limiting protrusions through the limiting grooves.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the limiting grooves on both sides of the connecting plate cooperate with the limiting protrusions to accurately limit the sliding direction of the connecting plate, ensuring the stable operation of the connecting structure, reducing the risk of component shaking during operation, and improving the overall stability and reliability of the plate.

[0017] Furthermore, the width of the reserved slot is greater than the width of the connecting plate and the connecting seat.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, since the width of the reserved groove is greater than the width of the connecting seat and the connecting plate, when the two plates are close to each other, they will not get stuck when they are close together due to the connecting seat or the connecting plate, thus improving the stability of the device during use.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, the calculation board assembly can be folded and stored during use due to the connecting folding component. Furthermore, the two boards are seamless during assembly, improving both usability and aesthetics. By placing the two boards horizontally and pushing them inward to make them fit together, the limiting protrusion moves from one end of the limiting groove to the other until the hole on the connecting plate fits the empty space on the board. Then, the connecting plate and the board are connected by the limiting bolt.

[0021] 2. In this utility model, under the action of the pressure strip assembly, when using the calculation board assembly later, the drawing can be fixed on the board body by the pressure strip assembly. By attaching the drawing to the surface of the board body through the pressure strip, it is easy to unfold the drawing for calculation. Furthermore, under the action of the elastic rope, a pulling force is applied to the pressure strip to prevent the drawing from separating from the elastic rope through the gap.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1-5 As shown, this utility model provides a technical solution: a portable cost auditing instrument, comprising:

[0033] The calculation board assembly 1 is composed of two plates 11. Each of the two plates 11 has a snap-fit ​​groove 12 at one end that is close to each other. A reserved groove 14 is provided on the side of the two snap-fit ​​grooves 12 away from the snap-fit ​​grooves 12. A limit protrusion 15 is provided on the reserved groove 14.

[0034] The connecting folding assembly 2 consists of a connecting plate 22 and a connecting seat 21 that are slidably connected to the limiting protrusion 15. Two connecting plates 22 are provided, and each connecting plate 22 is connected to its corresponding plate body 11. The ends of the two connecting plates 22 that are close to each other are rotatably connected to the connecting seat 21. A limiting groove 13 is provided on the snap-fit ​​groove 12. A protrusion 34 penetrating the limiting groove 13 is provided on the sliding snap-fit ​​seat 33. The sliding snap-fit ​​seat 33 is slidably connected to the limiting groove 13 through the protrusion 34. A through-hole is provided on the connecting plate 22 that connects to the plate body. The limiting bolt 24 connected to 11, under the action of the connecting folding component 2, allows the calculation board component 1 to be folded and stored during use, and improves the use effect and aesthetics by eliminating gaps between the two boards 11 during assembly. After the two boards 11 are placed horizontally, the boards 11 are pushed inward to make them fit together. At this time, the limiting protrusion 15 moves from one end of the limiting slide groove 23 to the other end until the hole on the connecting plate 22 fits with the empty space on the board 11. Then, the connecting plate 22 and the board 11 are connected by the limiting bolt 24.

[0035] Furthermore, such as Figure 2 - Figure 5 As shown: Pressure strip assembly 3, which consists of a sliding snap-fit ​​seat 33, an elastic rope 32 and a pressure strip 31 disposed inside the snap-fit ​​groove 12. The two ends of the pressure strip 31 are connected to the two sliding snap-fit ​​seats 33 through the elastic rope 32. Under the action of the pressure strip assembly 3, when using the calculation board assembly 1 later, the drawing can be fixed on the board body 11 through the pressure strip assembly 3. By attaching the drawing to the surface of the board body 11 through the pressure strip 31, the drawing can be unfolded for calculation. Furthermore, under the action of the elastic rope 32, a pulling force is applied to the pressure strip 31 to prevent the drawing from separating from the elastic rope 32 through the gap.

[0036] The above solution also has the problem of sliding separation between plate 11 and connecting plate 22 during use, such as... Figure 4 As shown: In this solution, limiting grooves 23 are provided on both sides of the connecting plate 22. The connecting plate 22 is slidably connected between the corresponding limiting protrusions 15 through the limiting grooves 23. The limiting grooves 23 on both sides of the connecting plate 22 cooperate with the limiting protrusions 15 to accurately limit the sliding direction of the connecting plate 22, ensuring the stable operation of the connection structure. During operation, it reduces the risk of component shaking and improves the overall stability and reliability of the plate 11.

[0037] The above solutions also have the problem of jamming when the two plates 11 come into contact with the connecting seat 21 or the connecting plate 22 during splicing. Figure 4 As shown: In this solution, the width of the reserved groove 14 is greater than the width of the connecting plate 22 and the connecting seat 21. Since the width of the reserved groove 14 is greater than the width of the connecting seat 21 and the connecting plate 22, when the two plates 11 are close to each other, they will not get stuck when they are attached due to the connecting seat 21 or the connecting plate 22, thus improving the stability of the device during use.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
