Description
Technical Field
[0001] This utility model relates to the field of engineering budgeting technology, and in particular to a construction engineering management engineering budget drawing device. Background Technology
[0002] A project budget is a plan for the income and expenditure of a project over a certain period in the future. It can evaluate the investment in a project in monetary terms and reflect the economic effect of the project. It serves as the basis for strengthening enterprise management, implementing economic accounting, assessing project costs, and preparing construction plans; it is also the main basis for project bidding and pricing and determining project costs. When preparing project budgets at some construction sites, staff need to draw up drawings on-site, thus requiring a portable drawing device.
[0003] Most existing drawing devices involve workers holding a drawing board to support the drawings. On the construction site, workers either hold the drawing board or place it on the ground to draw. When drawing with the drawing board held by hand, the stability is not high, resulting in poor drawing quality. When drawing on the ground, workers need to constantly change their body position to complete the drawing operation, which reduces the drawing efficiency. Therefore, there is room for improvement. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction project management and budget drawing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A construction project management budget drawing device includes a drawing board. A rotating groove is formed on the upper surface of the drawing board. Two clamping assemblies are rotatably connected to the inner wall of the rotating groove. Each clamping assembly includes a rotating column. A fixed frame is fixedly connected to the surface of the rotating column. Sliding grooves are formed on the opposite sides of the two fixed frames. Two sliders are slidably connected to the inner wall of the sliding groove. An arc-shaped gripper is fixedly connected to the side of the slider away from the inner wall of the sliding groove. A positive and negative threaded rod is rotatably connected to the inner wall of the sliding groove. A first bevel gear is fixedly connected to the surface of the positive and negative threaded rod. A rotating shaft is rotatably connected to the upper surface of the fixed frame. A second bevel gear is fixedly connected to the bottom end of the rotating shaft. A circular shaft is fixedly connected to the rear end of the rotating column. A rectangular groove is formed on the surface of the circular shaft. A movable plate is slidably connected to the inner wall of the rectangular groove. A limit block is fixedly connected to the upper surface of the movable plate. A first spring is fixedly connected to the inner bottom wall of the rectangular groove.
[0007] Preferably, the two sliders are threaded to the positive and negative threads on the surface of the positive and negative threaded rods, respectively, and the bottom end of the rotating shaft extends into the interior of the groove, with the first bevel gear meshing with the second bevel gear.
[0008] Preferably, the inner rear wall of the rotating groove has two circular grooves adapted to the circular shaft, the upper surface of the drawing board has two limiting holes adapted to the limiting block, and the end of the first spring away from the inner bottom wall of the rectangular groove is fixedly connected to the lower surface of the movable plate.
[0009] Preferably, the front of the drawing board has a storage slot, the inner wall of the storage slot is slidably connected to a drawing storage frame, and the front of the drawing storage frame is fixedly connected to a handle.
[0010] Preferably, the left and right inner walls of the storage slot are provided with movable slots, the inner walls of the two movable slots are fixedly connected with locking rods, the surfaces of the two locking rods are fitted with second springs, and the inner walls of the two movable slots are slidably connected with movable blocks.
[0011] Preferably, the opposite surfaces of the two movable blocks are fixedly connected to the left and right sides of the drawing storage frame, the two movable blocks are slidably connected to the surfaces of the two locking rods, the rear end of the second spring overlaps with the front end of the movable block, and the front end of the second spring overlaps with the inner front wall of the movable groove.
[0012] The beneficial effects of this utility model are as follows:
[0013] By using the clamping components, the reaction force generated by the first spring can lock the position of the rotating column by engaging the limiting block within the limiting hole. Simultaneously, the rotating shaft and the second bevel gear drive the first bevel gear and the forward and reverse threaded rods to rotate, thereby causing the two sets of arc-shaped grippers to move closer together and fix the drawing board on the surface of the columnar part. This allows workers to draw on the drawing board without needing to hold it by hand or draw on the ground, greatly improving drawing efficiency and quality. In addition, the drawing storage frame makes it easy to protect and store the drawings, preventing them from being lost or damaged. It is also portable, eliminating the need for workers to carry it.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example:
[0021] Reference Figure 1-4 A construction project management budget drawing device includes a drawing board 1. The upper surface of the drawing board 1 has a rotating groove. The inner wall of the rotating groove is rotatably connected to two clamping components. The clamping components include a rotating column 2. The surface of the rotating column 2 is fixedly connected to a fixed frame 3. The opposite surfaces of the two fixed frames 3 are each provided with a sliding groove. The inner wall of the sliding groove is slidably connected to two sliders 4. The side of the slider 4 away from the inner wall of the sliding groove is fixedly connected to an arc-shaped gripper 5. The inner wall of the sliding groove is rotatably connected to a positive and negative threaded rod 6. The surface of the positive and negative threaded rod 6 is fixedly connected to a first bevel gear 7. The upper surface of the fixed frame 3 is rotatably connected to a rotating shaft 8. The bottom end of the rotating shaft 8 is fixedly connected to a second bevel gear 9. The rear end of the rotating column 2 is fixedly connected to a circular shaft 10. The surface of the circular shaft 10 has a rectangular groove. The inner wall of the rectangular groove is slidably connected to a movable plate 11. The upper surface of the movable plate 11 is fixedly connected to a limit block 12. The inner bottom wall of the rectangular groove is fixedly connected to a first spring 13.
[0022] Two sliders 4 are threaded to the positive and negative threads on the surface of the positive and negative threaded rods 6 respectively, and the bottom end of the rotating shaft 8 extends into the interior of the groove. The first bevel gear 7 meshes with the second bevel gear 9. Two circular grooves adapted to the circular shaft 10 are opened on the inner rear wall of the rotating groove. Two limiting holes adapted to the limiting block 12 are opened on the upper surface of the drawing board 1. The end of the first spring 13 away from the bottom wall of the rectangular groove is fixedly connected to the lower surface of the movable plate 11.
[0023] When drawing operations are required on the construction site, first rotate the two rotating columns 2 so that the rotating columns 2 drive the fixed frame 3 to be perpendicular to the drawing board 1. At this time, the two rotating columns 2 can drive the circular shaft 10 to rotate. When the fixed frame 3 is perpendicular to the drawing board 1, the two limiting blocks 12 rotate to the limiting hole position. At this time, the two first springs 13 lose their restriction. Through the reaction force, the movable plate 11 drives the limiting blocks 12 to pass through the limiting hole, thereby locking the position of the circular shaft 10 and the rotating column 2. At this time, align the two sets of arc-shaped grippers 5 with the columnar part position, rotate the two rotating shafts 8 so that the second bevel gear 9 drives the first bevel gear 7 and the positive and negative threaded rod 6 to rotate. Thus, the two sliders 4 can drive the two arc-shaped grippers 5 to move closer to each other. The two sets of arc-shaped grippers 5 can be used to fix the drawing board 1 on the surface of the columnar part, which makes it convenient for the staff to draw on the drawing board 1 without the staff holding the drawing board 1 or drawing on the ground, which greatly improves the drawing efficiency and quality.
[0024] The front of the drawing board 1 has a storage slot, and the inner wall of the storage slot is slidably connected to a drawing storage frame 14. The front of the drawing storage frame 14 is fixedly connected to a handle 15. The left and right inner walls of the storage slot are each provided with a moving slot. The inner walls of the two moving slots are each fixedly connected to a locking rod 16. The surface of the two locking rods 16 is fitted with a second spring 17. The inner walls of the two moving slots are each slidably connected to a moving block 18. The opposite surfaces of the two moving blocks 18 are fixedly connected to the left and right sides of the drawing storage frame 14, respectively. The two moving blocks 18 are slidably connected to the surfaces of the two locking rods 16, respectively. The rear end of the second spring 17 overlaps with the front of the moving block 18, and the front end of the second spring 17 overlaps with the inner front wall of the moving slot.
[0025] The handle 15 moves the drawing storage frame 14 forward within the storage slot. Once the drawing storage frame 14 comes out, the drawing can be placed inside. When the handle 15 is released, the second spring 17 generates a reaction force, which, through the two moving blocks 18, moves the drawing storage frame 14 back into the storage slot. This provides some protection for the drawing and eliminates the need for staff to hold it, making it highly portable.
[0026] Working principle: First, when drawing is required at the construction site, rotate the two rotating columns 2 so that the two fixed frames 3 are perpendicular to the drawing board 1. At this time, the limiting blocks 12 on the surface of the two circular shafts 10 rotate to the limiting hole position, the first spring 13 loses its restraint, and through the reaction force, drives the movable plate 11 and the limiting block 12 to pop outward through the limiting hole, so that the limiting block 12 is stuck in the limiting hole position, thereby locking the position of the rotating column 2. Then, rotate the two rotating shafts 8, which drive the first bevel gear 7 in the slide groove to rotate through the second bevel gear 9, thereby driving the two sliders 4 and the arc-shaped grippers 5 to move closer to each other through the positive and negative threaded rods 6, until the two arc-shaped grippers 5 clamp the drawing board 1 into the fixed position on the columnar part. The design allows staff to easily draw on the drawing board 1 to depict the construction site without needing to hold the board or draw on the ground, improving drawing efficiency and quality. Furthermore, after drawing, pulling the handle 15 forward causes the drawing storage frame 14 to pop out of the storage slot. At this time, the two moving blocks 18 can move forward within the slot, squeezing the second spring 17 on the surface of the locking rod 16. After placing the drawing in the drawing storage frame 14 and releasing the handle 15, the second spring 17 generates a reaction force, causing the moving blocks 18 and the drawing storage frame 14 to return to their original positions, thus protecting the drawing and ensuring it is not lost. It also eliminates the need for staff to hold it, making it highly portable.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
