Description

Technical Field

[0001] This invention relates to the field of engineering cost technology, specifically to a file storage device for engineering cost. Background Technology

[0002] Construction cost estimation is a process that comprehensively utilizes knowledge and skills from management, economics, and engineering technology to predict, plan, control, calculate, analyze, and evaluate construction costs. It involves predicting or determining construction costs and their components in accordance with the procedures, methods, and bases stipulated by laws, regulations, and standards.

[0003] In their daily work, construction cost engineers often use document storage devices to organize and store important documents. Taking office desks as an example, while traditional desks provide a good desktop working environment and can utilize storage boxes to provide document storage space, they still have certain shortcomings in actual use. In construction cost engineering, staff often need to review and stamp documents of different formats. Due to the large number of documents that need to be reviewed in construction cost engineering, the traditional stamping process is quite inconvenient and brings a huge workload to the staff. Moreover, if the stamped area is not handled carefully after the documents are stamped, the documents may be stacked, which can easily cause the stamped area to be scratched, resulting in unclear documents and making them difficult to store.

[0004] The existing patent technology CN103802108A relates to a remote assisted office robot, which consists of a robot body and functional components such as a main camera, microphone, display, and speaker attached to the robot. A video display platform and a guide rail sleeve type electric stamping device are also fixed on the robot body. Through the design of the electromagnet's working stroke and the stamp installation position, when the authorization is energized, the stamp moves downward instantly under the force of the electromagnet, and the stamp working surface briefly contacts the paper on the text display platform to complete the stamping action. When the electromagnet is de-energized, the stamp working surface retracts back to above the lower end face of the stamp guide rail sleeve, returning to the normal position. Although this design can achieve barrier-free and efficient stamping of stored documents, it requires a spacious document storage device to accommodate the entry and exit of the electronic stamping module, so the applicable scenarios are relatively narrow. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-11 One embodiment provided by the present invention:

[0032] A document storage device for engineering cost estimates includes a storage assembly 100, which includes a desk 110. One end of the desk 110 has a first movement compartment 111, a second movement compartment 112, and a collection compartment 114. The second movement compartment 112 is located to the right of the first movement compartment 111, and the collection compartment 114 is located to the right of the second movement compartment 112. A connecting compartment 113 is formed on the inner wall of one side of the collection compartment 114, and the interior of the connecting compartment 113 is connected to the interior of the second movement compartment 112. The desk 110 has a storage compartment 115 inside. A stamping mechanism assembly 200 is fixedly connected to one end of the desk 110. The stamping mechanism assembly 200 includes an operating chamber 210, one end of which is fixedly connected to the surface of one end of the desk 110. A first fixed plate 211 is provided inside the first motion chamber 111, and a motion groove 212 is formed on the surface of the first fixed plate 211. A first motor 213 is installed on the inner wall of one side of the first motion chamber 111, and the output shaft of the first motor 213 extends through the first fixed plate 211 to one side of the first fixed plate 211. One side of the surface of the output shaft of the first motor 213 is connected by a shaft. The support frame is connected to the inner wall of one end of the first motion chamber 111. A first connecting rod 214 is hinged to one side of the output shaft of the first motor 213 via a hinge shaft. A first ball 225 is fitted inside one end of the motion groove 212, and one side of the central axis of the first ball 225 is hinged to one end of the first connecting rod 214 via a hinge shaft. A second connecting rod 215 is hinged to one side of the central axis of the first ball 225 via a hinge shaft, and one end of the second connecting rod 215 is hinged to a first pull rod 216 via a hinge shaft. One end of the first pull rod 216 is fixedly connected to a pusher. Block 218, one end of push block 218 extends through the first motion chamber 111 into the interior of the operation chamber 210, the surface of the first pull rod 216 is fitted with a sliding sleeve 217, and both sides of the sliding sleeve 217 are fixedly connected with sliding rods, the inner walls on both sides of the first motion chamber 111 are provided with sliding grooves that cooperate with the sliding rods, the operation chamber 210 is provided with a stamping motion mechanism assembly 230, the second motion chamber 112 is installed with a conveyor belt 227, the collection chamber 114 is provided with a pressing mechanism assembly 250, and the storage chamber 115 is provided with a sorting mechanism assembly 300;

[0033] Furthermore, a rubber pad is fixedly connected to the surface of one end of the push block 218, and the surface of the rubber pad is provided with anti-slip texture. Through the rubber pad fixedly connected to the surface of one end of the push block 218, when the push block 218 moves horizontally, the push block 218 can make good contact with the bottom of the document. The rubber pad can effectively increase the friction generated when the push block 218 moves and contacts the surface of the document, so that the document can be moved under force.

[0034] Furthermore, the operating chamber 210 is equipped with two sets of rollers 219, which are symmetrically distributed. One set of rollers 219 is located inside the first motion chamber 111. A third motion chamber 226 is opened at one end of the office desk 110. The interior of the third motion chamber 226 is connected to the interior of one side of the operating chamber 210. One side of the central shaft of one set of rollers 219 is connected to the inner wall of one side of the first motion chamber 111 through an embedded bearing. The other side of the central shaft of one set of rollers 219 extends through the first motion chamber 111 into the interior of the third motion chamber 226 and is connected to the inner wall of one side of the third motion chamber 226 through an embedded bearing. One side of the central shaft of the other set of rollers 219 is connected to the inner wall of one side of the operating chamber 210 through an embedded bearing. The other side of the central shaft of the other set of rollers 219 extends through the operating chamber 210 into the interior of the operating chamber 210 and is connected to the inner wall of the operating chamber 210 through an embedded bearing. A second motor 220 is installed at one end of one side of the 210, and the output end of the second motor 220 extends through the operating chamber 210 into the interior of the operating chamber 210. Gears 221 are sleeved on one side of the surface of the output shaft of the second motor 220 and one side of the central shaft surface of the two sets of rollers 219, and the gears 221 mesh with each other. The rollers 219, the second motor 220 and the gears 221 constitute a smoothing mechanism. When the document is pushed to the position between the rollers 219, the user turns on the second motor 220. Due to the turning on of the second motor 220, the output shaft of the second motor 220 can drive one set of gears 221 to continuously mesh with another set of gears 221 inside the operating chamber 210. After the other set of gears 221 is subjected to force, it drives the rollers 219 to rotate. Similarly, the meshing between the gears 221 can make the two sets of rollers 219 rotate in opposite directions. The rollers 219 can quickly roll the document placed in the middle and transfer it to the surface of the conveyor belt 227.

[0035] Furthermore, a pressing plate 222 is provided on one side of the operating chamber 210, and balls are evenly embedded on the surface of one end of the pressing plate 222. A second pull rod 223 is fixedly connected to the middle of the other end of the pressing plate 222, and one end of the second pull rod 223 extends through the operating chamber 210 to the outside of the operating chamber 210. Connecting springs 224 are provided on both sides of the surface of the pressing plate 222, and one end of each connecting spring 224 is fixedly connected to the surface of the pressing plate 222, while the other end of each connecting spring 224 is fixedly connected to the inner wall of one end of the operating chamber 210. The pressing plate 222 and the second pull rod 223 are... The compression mechanism is formed by the connecting spring 224. The user can quickly adjust the distance between the compression plate 222 and the desk 110 by pulling the second pull rod 223 according to the number and thickness of the documents to be stamped. The user pulls the compression plate 222 to adjust the distance between the compression plate 222 and the desk 110 to a suitable position. The user places the documents to be reviewed under the compression plate 222. Then the user releases the pull rod 223, and the compression plate 222 can contact the surface of the documents to compress them. This ensures the stability of the other documents when the push block 218 pushes the documents.

[0036] Furthermore, the stamping motion mechanism assembly 230 includes a third motor 231. The output shaft of the third motor 231 extends through the operating chamber 210 and into its interior. A rotating disk 232 is fixedly connected to one side of the output shaft of the third motor 231. A printing ink collection tank 233 is fixedly connected to one end of the operating chamber 210. A fixing sleeve 234 is fixedly connected to the inner wall of one end of the operating chamber 210. A first connecting groove 235 is formed inside the fixing sleeve 234, and the interior of the first connecting groove 235 communicates with the interior of the printing ink collection tank 233. A moving rod 236 is inserted into one end of the fixing sleeve 234, and one end of the moving rod 236 extends through the fixing sleeve 234 into the interior of the first connecting groove 235. The moving rod 236 further extends into the first connecting groove 235. A sponge stamp 237 is embedded inside one end of the moving rod 236. A second connecting groove 238 is opened inside the moving rod 236. A second ball 239 is connected to one side of the moving rod 236 through an embedded shaft. One side of the second ball 239 extends through the rotating disk 232 into the interior of the rotating disk 232. One end of one side of the second ball 239 abuts against one end of the inner wall of the rotating disk 232. A second fixing plate 240 is fixedly connected to the inner wall of one end of the first connecting groove 235. A first sealing plate 241 is inserted into one end of the second fixing plate 240. One end of the first sealing plate 241 extends through the second fixing plate 240 into the interior of the second fixing plate 240. A torsion spring is sleeved on one end of the surface of the second fixing plate 240. One end of the torsion spring is connected to the second fixing plate 240. The surface of the first sealing plate 241 is fixedly connected to the surface of the second connecting groove 238. A third fixing plate 242 is fixedly connected to the inner wall of one end of the second connecting groove 238. A second sealing plate 243 is inserted into one end of the third fixing plate 242, and one end of the second sealing plate 243 extends through the third fixing plate 242 into its interior. A torsion spring is fitted onto one end of the surface of the third fixing plate 242, with one end fixedly connected to the surface of the third fixing plate 242 and the other end fixedly connected to one end of the second sealing plate 243. When the document is conveyed by the conveyor belt 227 to the area below the sponge stamp 237, the user can turn on the third motor 231. The output end of the third motor 231... The rotating disk 232 rotates inside the operating chamber 210, causing the moving rod 236 to reciprocate inside the first connecting groove 235. When the moving rod 236 moves downward, it drives the sponge stamp 237 to quickly stamp the document. The downward movement of the moving rod 236 causes a pressure change inside the first connecting groove 235. Through this pressure difference, the first sealing plate 241 quickly moves downward inside the first connecting groove 235, causing the ink stored in the ink collection box 233 to flow rapidly into the first connecting groove 235. When the document retracts upward, the moving rod 236 quickly retracts inside the first connecting groove 235.This allows the pressure inside the first connecting groove 235 to be restored, and the second sealing plate 243 to move downwards inside the second connecting groove 238. This allows the oil collected inside the first connecting groove 235 to flow smoothly through the second connecting groove 238 to the inside of one end of the moving rod 236, thus impregnating the sponge stamp 237 and replenishing the ink in the sponge stamp 237.

[0037] Furthermore, sliders are fixedly connected to one end of both sides of the moving rod 236, and grooves that cooperate with the sliders are opened on the inner walls of both sides of the first connecting groove 235. Springs are installed inside the grooves, one end of the springs is fixedly connected to the sliders, and the other end of the springs is fixedly connected to the inner wall of one end of the groove. When the moving rod 236 moves inside the first connecting groove 235 through the sliders fixed to one end of both sides of the moving rod 236, the moving rod 236 can drive the sliders to slide inside the grooves. Through the cooperation between the sliders and the grooves, the movement trajectory of the moving rod 236 can be well limited. When the moving rod 236 moves downward and causes the sponge stamp 237 to come into contact with the document, the moving rod 236 contracts to a certain extent inside the first connecting groove 235, and the slider moves inside the groove, squeezing the springs and causing the springs to deform, thus effectively buffering the squeezing force of the sponge stamp 237.

[0038] Furthermore, the pressing mechanism assembly 250 includes a connecting plate 251, inside which a plastic film 252 is disposed, and both sides of the plastic film 252 are fixedly connected to the inner wall of the connecting plate 251. A fourth motion chamber 253 is formed on the inner wall of one side of the collection chamber 114, and a threaded rod 254 is disposed inside the fourth motion chamber 253. One end of the threaded rod 254 is connected to the inner wall of one end of the fourth motion chamber 253 through an embedded bearing. The other end of the threaded rod 254 extends through the desk 110 to the outside of the desk 110. A threaded sleeve 255 is fitted on one end of the surface of the threaded rod 254, and one side of the threaded sleeve 255 extends through the fourth motion chamber 253 to the inside of the collection chamber 114 and is fixedly connected to the connecting plate 251. A movable plate 256 is disposed at one end of the connecting plate 251, and both sides of one end of the movable plate 256 are fixed. The connecting plate 251 is connected to a slider. The surfaces on both sides of one end of the connecting plate 251 are provided with grooves that cooperate with the slider. The moving plate 256 is provided with a rolling rod 257 inside. Both ends of the central shaft of the rolling rod 257 are connected to the inner walls on both sides of the moving plate 256 through embedded bearings. When the document slides into the collection chamber 114, the user can simply turn the threaded rod 254 to move the connecting plate 251 inside the collection chamber 114 until the moving connecting plate 251 moves and drives the plastic film 252 to the document surface. Then, the user can simply pull the moving plate 256 to make the moving plate 256 quickly move across the surface of the connecting plate 251, so that the plastic film 252 can quickly come into contact with the surface of the plastic film 252 and roll, thereby effectively pressing the document stamping position and absorbing excess oil at the document stamping position.

[0039] Furthermore, the sorting mechanism component 300 includes a first partition plate 310 located at the center of the storage compartment 115. Both ends of the first partition plate 310 are fixedly connected to the inner walls at both ends of the storage compartment 115. A second partition plate 311 is uniformly fixedly connected to one side of the surface of the first partition plate 310. One side of each second partition plate 311 is fixedly connected to one side of the inner wall of the storage compartment 115. Abutment plates 313 are uniformly provided on the inner walls at both ends of the storage compartment 115 and on the surfaces at both ends of the second partition plate 311. Four sets of abutment plates 313 are provided on one side of the first partition plate 310, and the four sets of abutment plates 313 are longitudinally distributed. Sliding blocks 314 are fixedly connected to both ends of each abutment plate 313, and one end of each sliding block 314 passes through a sliding groove 3. 12 extends into the interior of the sliding groove 312. A door panel 315 is provided on one side of the storage compartment 115, and the surface of the door panel 315 is hinged to the surface of the desk 110 via a hinge shaft. Users can classify and store documents and office supplies according to the capacity of the internal space of the storage compartments 115 on both sides of the first partition 310. For some smaller documents, users can simply pull the abutment plate 313 to adjust its position. Users can arrange the documents on the surface of the second partition 311 and the inner wall of one end of the storage compartment 115 according to the number of documents to be stored. Then, users insert the sliding block 314 into the interior of the sliding groove 312 so that the sliding block 314 can make good contact with the documents and clamp the documents to ensure the stability of the documents.

[0040] Working Principle: When using this device to stamp documents for approval, the user can connect the first motor 213, the second motor 220, and the third motor 231 to an external power source, enabling them to operate normally. Then, depending on the quantity and thickness of the documents to be stamped, the user can quickly pull the second lever 223. Under pressure, the second lever 223 moves the pressing plate 222 upwards within the operating chamber 210. Simultaneously, as the pressing plate 222 moves upwards, it presses the connecting spring 224. Under pressure, the connecting spring 224 deforms rapidly, allowing the user to easily adjust the distance between the pressing plate 222 and the desk 110. Until the user pulls the compression plate 222 to adjust the distance between the compression plate 222 and the desk 110 to a suitable position, the user places the document to be reviewed under the compression plate 222, with the bottom of the document abutting against the surface of the push block 218. Then, the user releases the pull rod 223. Through the rebound force of the connecting spring 224, the connecting spring 224 can quickly drive the compression plate 222 to automatically reset. The compression plate 222 can then contact the surface of the document, compressing the document. Subsequently, the user can turn on the first motor 213. After the first motor 213 is turned on, its output end drives the first connecting rod 214 to rotate on the surface of the first fixed plate 211. While the first connecting rod 214 is rotating, The first ball 225 can be pulled to roll rapidly inside the second motion chamber 112. Due to the movement of the first ball 225, the first ball 225 can exert a pulling force on the first pull rod 216 through the second linkage 215, causing the first pull rod 216 to be stressed and drive the push block 218 to translate inside the first motion chamber 111. The push block 218 can quickly push the bottom document to the position between the rollers 219. Then the user turns on the second motor 220. Due to the activation of the second motor 220, the output shaft of the second motor 220 can drive a set of gears 221 to continuously mesh with another set of gears 221 inside one side of the operating chamber 210, causing the other set of gears 221 to be stressed and drive the rollers 219. 9. Similarly, the meshing of gears 221 allows the two sets of conveyor rollers 219 to rotate in opposite directions. The conveyor rollers 219 can quickly roll the document placed in the middle, transferring it to the surface of the conveyor belt 227. Then, the user turns on the conveyor belt 227, which quickly transfers the document to below the sponge stamp 237. Subsequently, the user can turn on the third motor 231. After the third motor 231 is turned on, its output end drives the rotating disk 232 to rotate inside the operating chamber 210. When the rotating disk 232 rotates, the inner wall of one end of it always contacts the second ball 239, causing the second ball 239 to roll and rotate. The second ball 239 rotates with the rotating disk 232.The moving rod 236 reciprocates inside the first connecting groove 235. When the moving rod 236 moves downward, it can drive the sponge stamp 237 to quickly stamp the document. The downward movement of the moving rod 236 causes a change in pressure inside the first connecting groove 235. Through the pressure difference created inside the first connecting groove 235, the first sealing plate 241 quickly moves downward inside the first connecting groove 235, causing the ink stored inside the ink collection box 233 to flow rapidly. When the document retracts upwards, the moving rod 236 rapidly retracts inside the first connecting groove 235, causing the pressure inside the first connecting groove 235 to re-emerge. The second sealing plate 243 then displaces downwards inside the second connecting groove 238, allowing the oil collected inside the first connecting groove 235 to flow smoothly through the second connecting groove 238 to the inside of one end of the moving rod 236, thus impregnating the sponge stamp 237 and replenishing the ink. After the document is stamped, the document... The item can be moved to the interior of the connecting chamber 113 via the conveyor belt 227, and finally slides into the collection chamber 114 for proper collection. Then, the user can easily rotate the threaded rod 254 by twisting it, causing it to rotate within the fourth motion chamber 253. During rotation, the threaded rod 254 and the threaded sleeve 255 engage through their threaded structure, allowing the threaded sleeve 255 to slide quickly on the surface of the threaded rod 254. When the threaded sleeve 255 moves, it drives the connecting plate 251 to move inside the collection chamber 114 until the connecting plate 251 moves and causes the plastic film 252 to adhere to the document surface. Then, the user can simply pull the moving plate 256, causing it to quickly slide across the surface of the connecting plate 251. This causes the rolling rod 257 to quickly contact the surface of the plastic film 252 and roll, effectively pressing down on the document's stamping area and absorbing excess oil.

[0041] Next, when using the device, the user can classify and store documents and office supplies according to the capacity of the storage compartments 115 on both sides of the first partition 310. For some smaller documents, the user can simply pull the contact plate 313, so that the contact plate 313 is under force and quickly drives the sliding block 314 to slide inside the sliding groove 312 until the sliding block 314 slides out of the sliding groove 312. The user can then arrange the documents on the surface of the second partition 311 and the inner wall of one end of the storage compartment 115 according to the number of documents to be stored. Then, the user inserts the sliding block 314 into the sliding groove 312 again, so that the sliding block 314 can make good contact with the documents and hold them in place, ensuring the stability of the documents.

[0042] With its categorization mechanism, the device effectively divides the storage compartment using a first partition and a sliding groove. This allows users to adjust the storage based on the required volume and quantity of files, facilitating file categorization. Simultaneously, users can adjust the position of the files on the second partition by pulling a stop plate. The stop plate effectively clamps and secures the files, ensuring stability and preventing tilting that could affect storage quality.
