Description

Technical Field

[0001] This utility model belongs to the field of engineering cost, and more specifically, it relates to a cost settlement and recording device. Background Technology

[0002] Cost settlement in engineering project management is the process of systematically reviewing, verifying, summarizing, and analyzing all costs incurred throughout the entire project after its completion. It provides a basis for project settlement, financial auditing, performance evaluation, and subsequent project management. Currently, the cost settlement recording process requires engineering cost personnel to conduct analysis and calculations on multiple sheets of paper during on-site inspections. Since these sheets are typically independent and scattered, the analysis and calculation process cannot be continuously recorded. After each calculation, the cost cost personnel must arrange and stack the sheets according to the analysis process for subsequent cost verification. Therefore, this method of writing calculation records on multiple sheets cannot ensure the continuity of the analysis process, and the process of organizing and arranging the sheets after calculation is cumbersome and complex.

[0044] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0045] like Figures 1-10As shown, this utility model provides a cost settlement and recording device, including a housing 2; a writing board 20 is welded to the upper side of the housing 2, and a flip cover 1 is hinged to the rear side of the housing 2; an iron sheet 8 is glued to the upper side of the flip cover 1, and an iron strip 6 is glued to the front side of the flip cover 1; it also includes a transmission rod 10, a paper rolling device 13, and a guide rod 18; the housing 2 is welded to both the front and rear ends of the guide rod 18, and a sliding plate 15 is slidably connected to the outer side of the guide rod 18; clamps are rotatably connected to the front side of the sliding plate 15 near the left and right ends. The outer side of the mounting column 14 and guide rod 18 is welded with a vertical plate 17. The front side of the vertical plate 17 is rotatably connected to the left and right ends of the column 17. The center of the vertical plate 17 is provided with a through hole. The threaded rotating rod 16 is rotatably connected in the through hole of the vertical plate 17. The front end of the threaded rotating rod 16 is welded with a clamping knob 4. The outer side of the transmission rod 10 is welded with a helical gear 11. The left end of the transmission rod 10 is welded with a paper conveying knob 3. The outer side of the transmission rod 10 is rotatably connected to the housing 2. The upper side of the housing 2 is glued with a magnetic sheet 9.

[0046] In this embodiment of the utility model, the paper rolling device 13 includes a pressure cylinder 1301, a locking post 1302, a sleeve 1303, and a support rod 1304. The outer side of the support rod 1304 is provided with two sets of protruding plates. Locking posts 1302 are welded to both the front and rear ends of the support rod 1304. The outer side of the locking post 1302 is provided with a threaded structure, and a rectangular groove is provided at the center of the end of each set of locking posts 1302. There are two sets of sleeves 1303, each set being a semi-circular curved plate structure. Wrapping paper 19 is wound around the outer side of the semi-circular curved plate structure of the sleeve 1303. A long groove is provided on the inner side of the semi-circular curved plate structure of the sleeve 1303. The two sets of protruding plates of the support rod 1304 are respectively embedded in the long groove of the sleeve 1303. The outer side of the sleeve 1303... A ring plate is provided on the side near the front and rear ends. The ring plate of the support rod 1304 has a protrusion with a bevel structure. The inner side of the pressure cylinder 1301 has a threaded structure. The inner side of the pressure cylinder 1301 is threadedly engaged with the outer side of the locking post 1302. During the rotation of the pressure cylinder 1301, it rotates and moves back and forth along the locking post 1302. The end of the pressure cylinder 1301 pushes the protrusion and bevel structure of the clamp 1303, so that the two sets of clamps 1303 clamp the end of the draft paper 19 from left to right. This makes it easier for the paper winding device 13 to drive the draft paper 19 to be stably wound on the outer side of the clamp 1303, avoiding slippage of the draft paper 19 when it is wrapped on the outer side of the clamp 1303, and ensuring that the draft paper 19 can be wound and moved left and right between the paper winding devices 13.

[0047] In this embodiment of the utility model, a threaded through hole is provided at the center of the front side of the slide plate 15. The outer side of the threaded rotating rod 16 is threadedly engaged with the threaded through hole of the slide plate 15. Both sides of the threaded through hole of the slide plate 15 are provided with through holes that pass through from front to back. The guide rod 18 is inserted into the through hole structure of the slide plate 15. During the process of the clamping knob 4 driving the threaded rotating rod 16 to rotate, the threaded rotating rod 16 drives the outer side of the slide plate 15 to move back and forth along the guide rod 18. The slide plate 15 drives the cuboid protrusion of the clamping column 14 connected to the rotating rod to penetrate into the rectangular groove of the clamping column 1302, so that the rotating column 12 connected to the upright plate 17 cooperates with the clamping column 14 to clamp the paper rolling device 13 from front to back. The paper rolling device 13 is easy and quick to assemble and disassemble. When the writing paper 19 is full, the paper rolling device 13 can be quickly replaced between the rotating column 12 and the clamping column 14 with the wrapped writing paper 19.

[0048] In this embodiment of the utility model, the flip cover 1 is a rectangular groove structure. A partition is provided at the center of the rectangular groove structure of the flip cover 1. A digital calculator 21 is installed on the left side of the partition. The digital calculator 21 facilitates the cost estimator to quickly calculate the project cost, reducing the mental calculation activity of the cost estimator and making it easier for the cost estimator to quickly obtain the calculation results. The front side of the flip cover 1 is provided with a long through groove. A sliding cover 5 is inserted in the long through groove of the flip cover 1. The sliding cover 5 is an L-shaped structure. A magnetic strip 7 is glued to the bent part of the L-shaped structure of the sliding cover 5. When the magnetic strip 7 is attracted to the iron strip 6, the sliding cover 5 forms a closed space on the right side of the partition of the rectangular groove structure of the flip cover 1, thereby sealing and storing the draft paper 19 wound by the paper rolling device 13 that is replaced and disassembled.

[0049] In this embodiment of the utility model, there are two sets of rotating columns 12. Each set of rotating columns 12 has a cylindrical protrusion on its rear side and a helical external tooth structure on its outer side. Two sets of helical gears 11 welded to the outer side of the transmission rod 10 are respectively meshed and connected to the helical external tooth structure of the protrusion of the two sets of rotating columns 12. The front side of the rotating column 12 has a cuboid protrusion. The cuboid protrusion of the rotating column 12 is embedded in the rectangular groove of the clamping column 1302. During the process of the paper conveying knob 3 driving the transmission rod 10 to rotate, the transmission rod 10 drives the two sets of rotating columns 12 to rotate synchronously in the through hole of the upright plate 17 through the two sets of helical gears 11 welded to its outer side. This causes the cuboid protrusion of the rotating column 12 to drive the two sets of clamping columns 1302 of the paper winding device 13 to rotate synchronously, thus completing the left and right movement and conveying of the draft paper 19 between the two sets of paper winding devices 13.

[0050] In this embodiment of the utility model, there are two sets of clamping columns 14. Each set of clamping columns 14 has a cuboid protrusion on its rear side. The cuboid protrusion of the clamping column 14 is embedded in the rectangular groove of the clamping column 1302. When the rotating column 12 drives the paper winding device 13 to rotate, the clamping column 1302, which is welded to the front end of the support rod 1304, drives the clamping column 14 to rotate synchronously. This effectively avoids relative sliding or offset between the paper winding device 13 and the clamping column 14 and the clamping column 1302, so that the tension of the draft paper 19 can remain stable during the paper winding process. This prevents the draft paper 19 from being too loose or too tight due to transmission deviation, and ensures the neatness of the draft paper 19 winding for cost settlement records.

[0051] Specific usage and function of this utility model embodiment:

[0052] In this invention, when the paper winding device 13 is clamped between the clamping column 14 and the rotating column 12, the rectangular groove of the locking post 1302 at the rear end of the support rod 1304 in the paper winding device 13 is first inserted into the outer side of the cuboid protrusion of the rotating column 12. Then, the clamping knob 4 is manually rotated to drive the threaded rotating rod 16 to rotate. Since the threaded rotating rod 16 is engaged in the threaded through hole of the slide plate 15, the rotation of the threaded rotating rod 16 drives the slide plate 15 to move backward along the guide rod 18 until the cuboid protrusion of the clamping column 14, which is rotatably connected to the slide plate 15, penetrates into the rectangular groove of the locking post 1302 at the front end of the support rod 1304, thereby... After completing the clamping operation of the paper winding device 13 between the clamping column 14 and the rotating column 12, when clamping the end of the draft paper 19 between the paper winding device 13, the end of the draft paper 19 is inserted between the two sets of clamping sleeves 1303. Then, the two sets of pressure cylinders 1301 are manually rotated. Since the inner surface of the pressure cylinder 1301 is threadedly engaged with the outer surface of the clamping column 1302, the two sets of pressure cylinders 1301 move forward and backward along the thread structure of the two sets of clamping columns 1302 during rotation. This causes the pressure cylinders 1301 to push against the inclined surface structure of the ring plate protrusion of the clamping sleeve 1303, allowing the two sets of clamping sleeves 1303 to clamp the end of the draft paper 19 from left to right. After the draft paper 19 is clamped between the paper rolling device 13, when the cost estimator is performing continuous calculations and analyses on the draft paper 19, if the current writing area of ​​the draft paper 19 is used up, the paper feed knob 3 is manually turned. The paper feed knob 3 drives the two sets of helical gears 11 welded to the outer side of the transmission rod 10 to rotate. Since the two sets of helical gears 11 are respectively meshed with the helical external tooth structure of the two sets of rotating columns 12, the two sets of helical gears 11 of the transmission rod 10 drive the two sets of rotating columns 12 to rotate synchronously. The cuboid protrusions of the two sets of rotating columns 12 drive the support rod 1304 to rotate through the rectangular groove of the locking post 1302, thus completing the process. The two sets of paper rolling devices 13 convey and move the draft paper 19 wrapped around the outer sides of the two sets of jackets 1303 from left to right. If it is necessary to review the calculation and analysis process, the paper conveying knob 3 is rotated in the opposite direction. The paper conveying knob 3 drives the two sets of spiral gears 11 welded to the outer side of the transmission rod 10 to rotate in the opposite direction. The two sets of spiral gears 11 of the transmission rod 10 drive the two sets of rotating columns 12 to rotate in the opposite direction synchronously. The cuboid protrusions of the two sets of rotating columns 12 drive the support rod 1304 to rotate in the opposite direction through the rectangular groove of the locking column 1302, thereby completing the conveying and moving of the two sets of paper rolling devices 13 to the outer sides of the two sets of jackets 1303 from right to left.

[0053] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies. Any method that achieves the desired effect can be implemented. The digital calculators 21 used above are all common market components. Upon purchase, they can be used simply by connecting them according to the instruction manual purchased with the product; therefore, further details are omitted here.
