Description
Technical Field
[0001] This utility model relates to the field of engineering cost recording technology, and in particular to a classification and statistical recording device for engineering costs. Background Technology
[0002] Construction cost refers to the calculation and determination of all expenses required for a construction project during the construction process. It covers all costs from project planning, design, construction to final acceptance. When preparing a cost budget, it is necessary to record and compare different types of data. Categorized and statistical records make the budget document structure clear, identify potential errors or unreasonable aspects, and also help to classify and organize the data. In this process, it is necessary to use a categorized and statistical recording device to improve work efficiency. Technicians can use the categorized recording device to quickly record key information such as material usage and required data at the construction site and during on-site inspections.
[0003] Existing classification and statistical recording devices consist of a book clip and a load-bearing plate. Paper is then fixed to the load-bearing plate for engineering data statistics and recording. However, when it is necessary to view information such as the price, quantity, and specifications of multiple materials at the same time, the recording area is not large enough, and these data cannot be displayed simultaneously. Especially when dealing with a large number of numbers and complex formulas, frequent switching between different pages can easily lead to misreading or incorrect data recording. Therefore, a classification and statistical recording device for engineering cost is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a classification and statistical recording device for engineering cost, which aims to improve the problems of existing devices having relatively simple functions, difficulty in displaying comprehensive information, inconvenient data comparison and page turning, and thus affecting the accuracy of overall engineering cost budget.

[0006] The adjustment assembly includes a second connecting rod, one end of which is fixedly connected to the side wall of the second writing board. The outer wall of the second connecting rod is slidably connected to the inner wall of the first limiting groove. A retaining plate is fixedly connected to the outer wall of the second writing board, and a telescopic plate is fixedly connected to the outer wall of the retaining plate. A second limiting groove is formed on the side wall of the second writing board, and a fastener is slidably connected to the outer wall of the second limiting groove. A third spring is provided on the outer wall of the fastener, one end of which is fixedly connected to the inner wall of the first writing board. A fixing assembly is provided on the upper surface of the first writing board.
[0007] Furthermore, the fixing component includes a sliding block, which is slidably connected to a sliding groove. The outer wall of the sliding groove is formed on the upper surface of the writing board. A connecting post is fixedly connected to the upper surface of the sliding block. A spring is provided inside the connecting post, and a connecting rod is fixedly connected to one end of the spring.
[0008] Furthermore, the lower surface of the connecting rod is slidably connected to the upper surface of the writing board, and the connecting rod is used to assist the writing board in fixing the paper.
[0009] Furthermore, a connecting block two is fixedly connected to the upper surface of the writing board one, and a connecting rod three is connected through the interior of the connecting block two.
[0010] Furthermore, a connecting block is rotatably connected to the outer wall of the connecting rod three, and a fixing clamp is fixedly connected to the top of the connecting block one.
[0011] Furthermore, a second spring is provided on the lower surface of the fixing fixture, and one end of the second spring is fixedly connected to the upper surface of the writing board.
[0012] Furthermore, a fixing clamp two is fixedly connected to the top of the second spring, and the second spring is used to assist the fixing clamp one and the fixing clamp two in clamping and fixing the paper.
[0013] Furthermore, the bottom of the second fixing clamp is rotatably connected to the upper surface of the card plate, and the card plate is used to assist in the connection between the first writing board and the second writing board.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by pulling the buckle outward to disengage from the limiting groove 2, and then pulling the card plate outward to drive the writing board 2 out, the connecting rod 2 fixedly connected to the writing board 2 moves horizontally on the limiting groove opened on the outer wall of the writing board 1. At the same time, the telescopic plate fixedly connected to the card plate plays a role in stabilizing the writing board 2, thereby increasing the usable area of the work panel, allowing multiple data to be viewed at the same time, and reducing the risk of information omission.
[0016] 2. In this utility model, by lifting the connecting rod upward and sliding it to the desired position on the paper, the connecting rod is subjected to a force that drives the connecting column. The slider fixedly connected to the bottom of the connecting column moves in the groove to achieve the effect of adjustable size and preventing paper from curling. This keeps the writing surface flat, ensuring that all recorded information is clearly visible and reducing the possibility of information loss. Attached Figure Description

[0023] 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.
[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a classification and statistical recording device for engineering cost, including a writing board 1, a limiting groove 4 is provided on the side wall of the writing board 1, a writing board 2 9 is slidably connected inside the writing board 1, the writing board 2 9 is used to expand the recording work area, and an adjustment component is fixedly connected to the outer wall of the writing board 2 9.
[0025] The adjustment assembly includes a connecting rod 210, one end of which is fixedly connected to the side wall of the writing board 29, and the outer wall of the connecting rod 210 is slidably connected to the inner wall of the limiting groove 14. A locking plate 12 is fixedly connected to the outer wall of the writing board 29, and a telescopic plate 13 is fixedly connected to the outer wall of the locking plate 12. The telescopic plate 13 is used to stably connect the writing board 29 and the writing board 11. A limiting groove 20 is opened on the side wall of the writing board 29, and a fastener 18 is slidably connected to the outer wall of the limiting groove 20. A spring 319 is provided on the outer wall of the fastener 18, one end of which is fixedly connected to the inner wall of the writing board 11. A fixing assembly is provided on the upper surface of the writing board 11.
[0026] Specifically, by pulling outwards, the latches 18 on both sides of the writing board 29 disengage from the limiting groove 20. Then, the latch plate 12 is pulled outwards, causing the writing board 29 to be pulled out. The connecting rod 210, which is fixedly connected to the writing board 29, moves horizontally on the limiting groove 4 opened on the outer wall of the writing board 11. At the same time, the telescopic plate 13, which is fixedly connected to the latch plate 12, stabilizes the writing board 29. When the required size is reached, the latches 18 are released. The spring 319, which is slidably connected to the outer wall of the latches 18, drives the latches into the limiting groove 20, achieving the effect of fixing the size. Then, the fixing clamp 211 is pressed down to place the recording paper in the middle position between the fixing clamp 211 and the writing board 29. Then, the fixing clamp 211 is released. The spring 16 loses its compressive force and releases its elasticity upwards, causing the fixing clamp 211 to fix the recording paper. The unfolded writing board 29 achieves the effect of data comparison and classification and expands the working area.
[0027] Reference Figure 2 and Figure 3 The fixing component includes a sliding block 6, which is slidably connected to a groove 5. The outer wall of the groove 5 is opened on the upper surface of the writing board 1. The groove 5 is used to help the sliding block 6 slide and limit its position on the upper surface of the writing board 1. A connecting post 8 is fixedly connected to the upper surface of the sliding block 6. A spring 7 is provided inside the connecting post 8. A connecting rod 3 is fixedly connected to one end of the spring 7. The connecting rod 3 is used to fix the edge of the paper to prevent it from curling.
[0028] Specifically, by lifting the connecting rod 3 upwards and sliding it to the desired position on the paper, the connecting rod 3 is subjected to a force that drives the connecting column 8. The slider 6, which is fixedly connected to the bottom of the connecting column 8, moves within the groove 5 to achieve the effect of adjustable size and preventing paper curling.
[0029] Working principle: First, press down on the fixing clamp 1 to place the recording paper between the fixing clamp 1 and the writing board 1. Then, release the fixing clamp 1. The spring 16 loses its compressive force and releases its elasticity upward, which drives the fixing clamp 1 to fix the recording paper and form a fixed effect. Then, lift the connecting rod 3 upward and slide it to the required position of the paper. The connecting rod 3 is driven by the force to drive the connecting column 8. The slider 6 fixedly connected to the bottom of the connecting column 8 moves in the slide groove 5 to achieve the effect of adjustable size and preventing the paper from curling.
[0030] Secondly, when it is necessary to expand the recording area, pull the buckles 18 on both sides of the writing board 29 outward to disengage from the limiting groove 20. Then, pull the clamp 12 outward to pull out the writing board 29. The connecting rod 210 fixedly connected to the writing board 29 moves horizontally on the limiting groove 4 opened on the outer wall of the writing board 11. At the same time, the telescopic plate 13 fixedly connected to the clamp 12 stabilizes the writing board 29. When the required size is reached, release the buckles 18. The spring 3 19 slidably connected to the outer wall of the buckles 18 drives the buckles into the limiting groove 20 to achieve the effect of fixing the size. Then, press down on the fixing clamp 211 to place the recording paper in the middle position between the fixing clamp 211 and the writing board 29. Then, release the fixing clamp 211. The spring 16 loses its compressive force and releases its elasticity upward, driving the fixing clamp 211 to fix the recording paper. The expanded writing board 29 achieves the effect of expanding the working area for data comparison and classification.
