Description

Technical Field

[0001] This application relates to the technical field of engineering cost estimation tools, specifically an engineering cost estimation file management cabinet. Background Technology

[0002] In the field of engineering cost estimation, evaluating the rationality and investment efficiency of total investment and individual investments, or assessing the management level and operating results of construction and installation companies, all require preliminary calculations of the proposed project. This process is inseparable from the analysis of relevant data such as land prices, construction and installation product prices, and equipment prices. This data is mostly stored in archival form, and to facilitate comparison, budgeting, and other statistical work, filing cabinets are typically used to store the relevant statistical data archives.

[0003] Currently, the application of filing cabinets is quite mature, and there are various types of filing cabinets on the market to meet different storage needs. For example, Chinese utility model patent CN214386684U discloses a filing cabinet for engineering cost, which reduces the risk of workers falling when placing a large number of documents on the top shelf of the cabinet by setting up a liftable and rotating basket. At the same time, when the basket is not in use, it can limit the movement of the basket to prevent workers from tripping, thus improving the convenience and safety of file storage to a certain extent.

[0004] However, in most existing filing cabinets, including those mentioned in the patent, the files are usually neatly arranged inside. When a file is taken out, the other files on either side of it often tip over due to loss of support. This means that when the file needs to be put back in its original position, the tilted files obstruct the process, making it difficult to place the file back in its original location. Users often need to manually right the tilted files before they can be put back in, causing considerable inconvenience and affecting the efficiency of file storage and retrieval.

[0005] Therefore, this application provides a file management cabinet for engineering cost estimates to solve the above problems. Utility Model Content

[0006] This application provides a file management cabinet for engineering cost estimation, aiming to solve the problems mentioned in the background art, such as the tendency of files on both sides to tip over after files are taken out, making it difficult to put the retrieved files back in their initial position due to the tilt of the adjacent files. This requires manual straightening of the tilted files to complete the return, causing inconvenience to users and affecting the efficiency of file storage and retrieval.

[0007] To achieve the above objectives, this application provides the following technical solution: a file management cabinet for engineering cost estimates, comprising a cabinet body and multiple partitions disposed within the cabinet body. The partitions divide the cabinet body into multiple storage layers for storing engineering cost estimates files. The cabinet body has a double door hinged to its open end, and each double door has a viewing mirror corresponding to a storage layer. To prevent files from tipping over within the storage layers, a straightening mechanism is provided within each storage layer. This mechanism includes multiple straightening plates arranged along the length of the storage layer. A horizontal plate is disposed on the storage layer away from its opening. An L-plate is fixedly connected to one end of each straightening plate near the horizontal plate, forming an n-shaped groove with an opening downwards to fit the horizontal plate. When placing files, the files are placed between two straightening plates, with the files contacting one of the straightening plates near the edge. Then, the other straightening plate is pushed towards the files, causing both straightening plates to clamp the files together, thereby fixing them in a vertical position. During the movement of the straightening plate, the n-shaped groove formed by the L-plate slides laterally along the surface of the horizontal plate. With the cooperation between the n-shaped groove and the horizontal plate, the straightening plate is prevented from undergoing large-scale displacement, thereby ensuring the straightening effect of the straightening plate on the archives.

[0008] Preferably, the straightening plate is trapezoidal in shape, wider at the front and narrower at the back. The larger front area allows for more stable contact with the archives, enhancing the gripping stability and preventing the archives from slipping off the front of the straightening plate during storage and retrieval. The smaller rear design reduces the space occupied and interference between the straightening plate and other structures within the storage layer, allowing for a more rational layout of multiple straightening plates within the storage layer and improving the utilization rate of storage space.

[0009] Preferably, to reduce the weight of the straightening plate: the straightening plate is a perforated plate made of stainless steel or plastic. The perforated design significantly reduces the weight of the straightening plate, lessens the pressure on the partition plates and cross plates during movement, reduces wear, and extends the service life of each component. At the same time, the lightweight straightening plate is easier for users to push and operate, saving physical effort.

[0010] Preferably, to reduce wear between the straightening plate and the partition plate, the lower end of the straightening plate is rotatably fitted with a plurality of first ball bearings for contacting the partition plate. The arrangement of the first ball bearings transforms the sliding friction between the straightening plate and the partition plate into rolling friction, greatly reducing the frictional force between the two, thereby reducing wear and extending the service life of the straightening plate and the partition plate.

[0011] Preferably, to reduce wear between the n-shaped groove and the horizontal plate, a plurality of second ball bearings are rotatably embedded within the n-shaped groove for contacting the horizontal plate. These second ball bearings convert the sliding friction between the n-shaped groove and the horizontal plate into rolling friction, reducing wear between them, protecting the structural integrity of the horizontal plate and the L-plate, and extending their service life.

[0012] Preferably, to reduce the stress on the front side of the straightening plate: a guide groove is formed on the partition plate near its front side, and a guide rod extending into the guide groove is fixedly connected to the lower end of the straightening plate near its front side. A bearing adapted to the guide groove is fitted onto the guide rod. The guide rod moves within the guide groove, guiding and supporting the front side of the straightening plate, preventing tilting or swaying during movement, and ensuring the straightening plate maintains a stable posture. The bearing converts the sliding friction between the guide rod and the guide groove into rolling friction, reducing frictional resistance and making the movement of the straightening plate smoother. It also reduces wear on the guide rod and guide groove, extending their service life.

[0013] Preferably, to prevent the archives from getting damp, a moisture-proof component is also included inside the cabinet. This component includes two grid panels disposed opposite each other within the cabinet. Both ends of the partition plate are fixedly connected to the two grid panels, forming a through groove between the grid panels and the cabinet body. A drying groove communicating with this through groove is provided at the bottom of the cabinet body, and a desiccant is placed within the through groove. This moisture-proof component effectively prevents the archives inside the cabinet from getting damp, maintaining their dryness and integrity, preventing mold growth and blurred writing due to moisture, and extending the lifespan of the archives. The desiccant absorbs and dries the air within the storage layer through the through groove and grid panels, and the drying groove facilitates desiccant replacement, ensuring the continuity of the moisture-proof effect.

[0014] This application effectively prevents files from tipping over within the storage layer, ensuring they remain upright at all times. This facilitates the accurate return of retrieved files to their initial position without the need for manual righting, reducing operational steps and improving the efficiency and convenience of file storage and retrieval. Furthermore, the combination of the n-shaped groove and the horizontal plate restricts the displacement of the straightening plate, guaranteeing a stable and reliable uprighting effect on the files.

[0015] This application, through the design of moisture-proof components, effectively prevents the archives inside the cabinet from getting damp, maintaining their dryness and integrity, avoiding problems such as mold and blurred writing caused by moisture, and extending the preservation life of the archives. The desiccant absorbs and dries the air within the storage layer through the channels and grilles, and the drying compartment facilitates desiccant replacement, ensuring the continuity of the moisture-proof effect.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 This embodiment provides a file management cabinet for engineering cost estimation, such as... Figure 1-4As shown, the file management cabinet includes a cabinet body 1 and multiple partitions 2 installed inside the cabinet body 1. The partitions 2 divide the cabinet body 1 into multiple storage layers 11 for storing engineering cost files. The cabinet body 1 has a double door 5 hinged to its open end. The double door 5 is equipped with a viewing mirror 51 corresponding to the storage layer 11. To prevent the files from tipping over inside the storage layer 11, a straightening mechanism 3 is installed inside the storage layer 11. The straightening mechanism 3 includes multiple straightening plates 31 arranged along the length of the storage layer 11. A horizontal plate 32 is installed on the storage layer 11 away from its opening. An L-plate 33 is fixedly connected to one end of the straightening plate 31 near the horizontal plate 32. An n-shaped groove 34 with an opening facing downwards is formed between the L-plate 33 and the straightening plate 31 to fit the horizontal plate 32. This system effectively prevents files from tipping over within the storage layer 11, ensuring they remain upright at all times. This facilitates the accurate return of retrieved files to their initial positions without the need for manual straightening, reducing operational steps and improving the efficiency and convenience of file storage and retrieval. Simultaneously, the cooperation between the n-shaped groove 34 and the horizontal plate 32 restricts the displacement of the straightening plate 31, ensuring a stable and reliable straightening effect on the files. When placing a file, it is positioned between the two straightening plates 31, with the file contacting one of the plates near the edge. The other straightening plate 31 is then pushed towards the file, causing both plates to clamp the file together, thus fixing it in a vertical position. During the movement of the straightening plate 31, the n-shaped groove 34 formed by the L-plate 33 slides laterally along the surface of the horizontal plate 32. The cooperation between the n-shaped groove 34 and the horizontal plate 32 prevents significant displacement of the straightening plate 31, thereby ensuring its effective straightening effect on the files.

[0020] The straightening plate 31 is trapezoidal in shape, wider at the front and narrower at the back. The larger front area allows for more stable contact with the files, enhancing the gripping stability and preventing files from slipping off the front of the straightening plate 31 during storage and retrieval. The smaller rear design reduces the space occupied and interference between the straightening plate 31 and other structures within the storage layer 11, allowing for a more rational layout of multiple straightening plates 31 within the storage layer 11 and improving the utilization rate of storage space. Due to the trapezoidal shape of the straightening plate 31, when gripping files, the larger front portion forms a wider contact area with the files, increasing friction and thus gripping the files more securely. The smaller rear portion reduces the possibility of collisions or obstructions with other structures such as the horizontal plate 32 and the inner wall of the cabinet 1 during movement or arrangement, making the movement of the straightening plate 31 smoother.

[0021] To reduce the weight of the straightening plate 31: The straightening plate 31 is a perforated plate, made of stainless steel or plastic. The perforated design significantly reduces the weight of the straightening plate 31, lessening the pressure on the partition plate 2 and cross plate 32 during movement, reducing wear, and extending the service life of each component. At the same time, the lightweight straightening plate 31 is easier for users to push and operate, saving physical effort. Using stainless steel improves the corrosion resistance and strength of the straightening plate 31, while using plastic further reduces cost and weight. Both materials have good durability, meeting the long-term use requirements of the filing cabinet. The perforated structure reduces the amount of material used in the straightening plate 31, thus directly reducing its overall weight. When the user pushes the straightening plate 31, the lighter weight reduces the pushing force required, making operation easier. Stainless steel, with its inherent chemical stability, resists corrosion from moisture and impurities in the air; plastic, with its lighter density and lower production cost, achieves weight reduction and cost reduction. Furthermore, the structural strength of both materials is sufficient to support the clamping force on the files.

[0022] To reduce wear between the straightening plate 31 and the partition plate 2, a plurality of first ball bearings 311 are rotatably embedded at the lower end of the straightening plate 31 for contacting the partition plate 2. The arrangement of the first ball bearings 311 transforms the sliding friction between the straightening plate 31 and the partition plate 2 into rolling friction, significantly reducing the frictional force between them, thereby reducing wear and extending the service life of both the straightening plate 31 and the partition plate 2. Simultaneously, the reduced friction makes the movement of the straightening plate 31 on the partition plate 2 smoother and more flexible, allowing users to quickly adjust the position of the straightening plate 31 according to the number and size of files. When the straightening plate 31 moves on the partition plate 2, the first ball bearings 311 at the lower end of the straightening plate 31 contact the surface of the partition plate 2. As the straightening plate 31 moves, the first ball bearings 311 rotate, converting the original sliding friction into rolling friction. Since the coefficient of friction of rolling friction is much smaller than that of sliding friction, it effectively reduces the frictional resistance between the two, reduces wear, and makes the movement of the straightening plate 31 more effortless and smooth.

[0023] To reduce wear between the n-shaped groove 34 and the horizontal plate 32, multiple second ball bearings 341 are rotatably embedded within the n-shaped groove 34 to abut against the horizontal plate 32. These second ball bearings 341 convert the sliding friction between the n-shaped groove 34 and the horizontal plate 32 into rolling friction, reducing wear, protecting the structural integrity of the horizontal plate 32 and the L-plate 33, and extending their service life. Simultaneously, the reduced friction makes it smoother for the centering plate 31 to slide along the horizontal plate 32, improving the ease of adjusting the position of the centering plate 31. When the n-shaped groove 34 slides along the surface of the horizontal plate 32, the second ball bearings 341 within the n-shaped groove 34 contact and roll against the surface of the horizontal plate 32, converting the sliding friction between the n-shaped groove 34 and the horizontal plate 32 into rolling friction. The rolling friction generates less resistance, thus reducing wear and making the movement of the centering plate 31 easier and smoother.

[0024] To reduce the stress on the front side of the straightening plate 31, a guide groove 21 is provided on the partition plate 2 near its front side. A guide rod 312 extending into the guide groove 21 is fixedly connected to the lower end of the straightening plate 31 near its front side. A bearing 313 adapted to the guide groove 21 is fitted on the guide rod 312. The guide rod 312 moves within the guide groove 21, guiding and supporting the front side of the straightening plate 31, preventing the front side of the straightening plate 31 from tilting or swaying during movement, and ensuring that the straightening plate 31 always maintains a stable posture. The bearing 313 converts the sliding friction between the guide rod 312 and the guide groove 21 into rolling friction, reducing frictional resistance and making the movement of the straightening plate 31 smoother. At the same time, it reduces the wear of the guide rod 312 and the guide groove 21, extending their service life. When the straightening plate 31 moves, the guide rod 312 on its lower front side moves synchronously with the straightening plate 31 within the guide groove 21 on the partition plate 2. The guide groove 21 restricts the direction of movement of the guide rod 312, thereby guiding the front side of the straightening plate 31 and preventing it from deviating. The bearing 313 on the guide rod 312 contacts the inner wall of the guide groove 21. When the guide rod 312 moves, the bearing 313 rolls, converting sliding friction into rolling friction, reducing the moving resistance, and making the movement of the straightening plate 31 smoother.

[0025] Example 2 Unlike Embodiment 1, to prevent the archives from getting damp, a moisture-proof component 4 is also included inside the cabinet 1. The moisture-proof component 4 includes two grid panels 41 positioned opposite each other inside the cabinet 1. The two ends of the partition plate 2 are fixedly connected to the two grid panels 41 respectively, forming a through groove 12 between the grid panels 41 and the cabinet 1. A drying groove 13 communicating with the through groove 12 is provided at the bottom of the cabinet 1, and a desiccant 42 is placed inside the through groove 12. This effectively prevents the archives inside the cabinet 1 from getting damp, maintaining the dryness and integrity of the archives, avoiding problems such as mold growth and blurred writing due to moisture, and extending the preservation life of the archives. The desiccant 42 can absorb moisture and dry the air inside the storage layer 11 through the through groove 12 and the grid panels 41, and the drying groove 13 facilitates the replacement of the desiccant 42, ensuring the continuity of the moisture-proof effect. Two opposing grid panels 41 are arranged inside the cabinet 1, forming a through groove 12 between the cabinet 1 and the cabinet body 1. The drying groove 13 at the bottom of the cabinet 1 is connected to the through groove 12. The desiccant 42 placed in the through groove 12 absorbs moisture from the air inside the through groove 12. Because the grid panels 41 are breathable, the air in the storage layer 11 circulates with the air in the through groove 12 through the grid panels 41, allowing the desiccant 42 to continuously absorb moisture from the air in the storage layer 11, reducing the humidity inside the cabinet 1 and preventing the archives from getting damp. When the desiccant 42 becomes saturated with moisture, it can be replaced through the drying groove 13 to maintain a good moisture-proof effect.

[0026] Among them, desiccant 42 can be common types such as silica gel desiccant and calcium chloride desiccant. Silica gel desiccant is a highly active adsorbent material, usually produced by reacting sodium silicate with sulfuric acid, followed by a series of post-treatment processes such as aging and acid soaking. It has the characteristics of high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. It can adsorb moisture in the air, and after adsorption saturation, it can be regenerated and reused by heating. Calcium chloride desiccant's main component is calcium chloride, which has a strong moisture absorption capacity. Its moisture absorption process is a chemical reaction, combining with water to form hydrates, thereby achieving the purpose of drying the air, making it suitable for use in high humidity environments.

[0027] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0028] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
