Technical Field

[0001] This invention relates to the field of accounting device technology, specifically to an accounting device and method. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN209690803U, which discloses an accounting device including a calculation table and a display screen. This not only improves replacement efficiency but also reduces equipment damage. The existing technical solutions mentioned above have the following drawbacks: they are all flat and cannot be adjusted to suit different usage angles. This leads to glare on the screen when there is light or sunlight, making it difficult for accounting personnel to see the data displayed on the screen, which can easily result in accounting errors. Furthermore, there is no corresponding dustproof structure, and dust adheres to the surface after prolonged use, making the device inconvenient to use. Therefore, an accounting device and method are proposed to solve the above-mentioned problems. Summary of the Invention

[0010] Preferably, the cleaning mechanism includes support rails, with support rails fixedly installed on both the front and rear sides of the inner wall of the protective cover. A sliding frame is slidably installed between the two support rails. A cleaning roller extending to the bottom of the inner wall of the sliding frame is slidably installed between the front and rear sides of the inner wall of the sliding frame.

[0015] Preferably, the inner top wall of the outer box is designed to be open, the protective cover is rotatably connected to the outer box via a hinge, a fixing lock connected to the outer box is provided on the rear side of the protective cover, and a carrying handle is provided on the rear side of the outer box.

[0016] Preferably, a method of using an accounting device includes the following steps:

[0017] S: Locate the locking mechanism on the back of the outer box that connects to the protective cover, open it, and then rotate the protective cover using the hinges to fully expose the opening in the top wall of the outer box for subsequent operations and access to the contents.

[0018] S: Adjust the tilt angle of the calculator as needed. First, adjust the angle of the base plate using the handle, and then adjust the strip plate to a suitable height under the support of the rotating cylinder and crossbar. Locate the pull ring on the strip plate and pull it outward. The pull ring will drive the pull rod to move outward in the through hole of the strip plate. The circular plate at one end of the pull rod will slide outward in the fixed cylinder. At the same time, the locking rod on the other side of the circular plate will move outward, and the telescopic spring will be stretched. When the strip plate is rotated to the appropriate position, release the pull ring. Under the elastic force of the telescopic spring, the circular plate will move inward, driving the locking rod to move inward until the locking rod is engaged in the corresponding circular groove on the base plate, thereby fixing the position of the strip plate.

[0019] S: When the calculator needs to be shaded, pull the ring upwards. The ring will cause the U-shaped rod to slide upwards within the rack. When the bottom of the U-shaped rod disengages from the slot on the bottom wall of the limiting frame, the ring can be pushed back and forth. The ring will cause the rack to slide within the limiting frame. Since the rack meshes with the bottom of the gear, the movement of the rack will cause the gear to rotate. The gear is fixed on the support rod, so the support rod will rotate accordingly. The connecting cylinder and baffle on the outside of the support rod will also rotate. After rotating the baffle to the appropriate shading position, push the U-shaped rod downwards so that its bottom re-engages into the corresponding slot on the bottom wall of the limiting frame, thereby fixing the position of the baffle. Then, accounting can be performed.

[0020] S: After the calculation is completed, when there is dust or stains on the surface of the calculator that need to be cleaned, first reset the sunshade mechanism, support mechanism and fixing mechanism, close the protective cover, find the pull bar at the top of the protective cover, hold the anti-slip sleeve on the pull bar, and push the pull bar back and forth. The pull bar drives the sliding frame to slide back and forth between the two support rails through the two vertical plates. The cleaning roller in the sliding frame is always in close contact with the top of the calculator under the action of the telescopic rod and connecting spring. As the sliding frame moves, the cleaning roller rolls on the top of the calculator, thereby cleaning the surface of the calculator. After cleaning, the whole device can be stored and carried easily through the carrying handle.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides an accounting device with the following advantages:

[0023] 1. This accounting device, through the setting of a fixing mechanism, a sunshade mechanism, and a support mechanism, utilizes the elasticity of a fixed spring to cause a pull rod to drive a limit block to clamp and fix the calculator. When the calculator needs to be placed, pull the strip plate, which drives two pull rods to move to the left. The pull rods drive the limit block to compress the fixing spring, at which point the calculator is placed into the base, so that the calculator is in contact with the bottom of the baffle. Then release the strip plate, the fixing spring returns to its original position, and push the limit block to move to the right until the limit block is in contact with the outside of the calculator, fixing the calculator. To remove the calculator, simply reverse the above steps. The angle of the baffle is adjusted through the meshing transmission of the rack and pinion. When sunshade is needed, pull the pull ring, which moves the U-shaped rod upward. The U-shaped rod disengages from the slot on the bottom wall of the limit frame. At this time, the rack can be pushed or pulled to slide within the limit frame. The rack drives the gear to rotate, and the gear drives the support rod to rotate. The support rod is connected to... The cylinder drives the baffle to rotate, thereby adjusting the baffle's angle to achieve a sunshade effect. After adjustment, the U-shaped rod is moved downwards to insert into the slot on the bottom wall of the limiting frame, fixing the position of the rack and thus fixing the baffle's angle. Utilizing the elasticity of the telescopic spring, the locking rod engages with the circular groove on the base plate, achieving both fixing and adjusting the baffle angle. When the baffle angle needs adjustment, the pull ring is pulled, causing the pull ring to slide the circular plate within the fixed cylinder via the pull rod. The circular plate compresses the telescopic spring, simultaneously moving the locking rod into the mounting hole, disengaging it from the circular groove on the base plate. At this point, the baffle can be rotated, rotating on the crossbar via the rotating cylinder. After adjusting to the appropriate angle, the pull ring is released, the telescopic spring returns to its original position, and the circular plate moves outwards. The circular plate then drives the locking rod to insert into the corresponding circular groove on the base plate, fixing the baffle angle. This achieves the purpose of easy angle adjustment and, through the design of the sunshade mechanism, makes the device more convenient to use.

[0024] 2. This accounting device, through the setting of a cleaning mechanism, relies on the elasticity of the connecting spring to keep the cleaning roller always in contact with the top of the calculator. The sliding frame slides on the support rail, driving the cleaning roller to clean the calculator surface. When it is necessary to clean the calculator surface, hold and pull the horizontal bar, pull the horizontal bar to move the vertical plate, the vertical plate drives the sliding frame to slide on the support rail, the sliding frame drives the cleaning roller to roll on the top of the calculator. Under the action of the connecting spring, the cleaning roller always maintains a tight contact with the top of the calculator, thereby cleaning away dust and other debris from the calculator surface, achieving the purpose of having a dustproof structure.

[0039] The fixing mechanism 3 includes a rotating seat 301. The rotating seat 301 is fixedly installed on the right side of the inner wall of the outer box 1, providing fixed support for the base 302, allowing the base 302 to rotate around it at a certain angle, which facilitates the adjustment of the tilt angle of the calculator 4. The base 302 is fixedly installed on the left side of the rotating seat 301. Two stop bars 303 are fixedly installed on the inner top wall of the base 302. The stop bars 303 limit the calculator 4 and prevent the calculator 4 from moving freely within the base 302. Connecting plates 304 are fixedly installed on both the front and rear sides of the base 302. A fixing plate 305 is fixedly installed between the left sides of the two connecting plates 304. A pull rod 306 extending to the right side of the fixing plate 305 is slidably installed on the left side of the fixing plate 305. The right side of the pull rod 306 is fixedly installed... A limit block 307 is installed, and the calculator 4 is movably installed on the inner side of the base 302 and attached to the bottom of the stop bar 303. The limit block 307 is attached to the outer side of the calculator 4. A fixing spring 308 is fixedly installed on the left side of the limit block 307 and is fixedly connected to the fixing plate 305 and sleeved on the outside of the pull rod 306. The spring 308 sleeved on the outside of the pull rod 306, and its elasticity makes the limit block 307 always maintain the limiting pressure on the calculator 4, ensuring the stable placement of the calculator 4. A strip plate 309 is fixedly installed between the left sides of the two pull rods 306. A base plate 310 is fixedly installed on the bottom of the base 302. A handle 311 is fixedly installed on the top of the base plate 310, which makes it convenient for the operator to adjust the angle of the base plate 310, thereby adjusting the tilt angle of the calculator 4.

[0040] The base plate 310 has at least five circular grooves on both the front and rear sides. The size of the circular grooves is adapted to the size of the locking rod 609. The inner side of the limiting block 307 is provided with a sponge pad. The inner side of the fixing plate 305 is provided with a through hole adapted to the pull rod 306.

[0041] The shading mechanism 5 includes a support plate 51. Two support plates 51 are fixedly installed on the top left side of the base plate 310. A support rod 52 is rotatably connected between the two support plates 51. A connecting cylinder 53 is fixedly installed on the outside of the support rod 52. A baffle 54 located on the left side of the fixed plate 305 is fixedly installed on one side of the connecting cylinder 53. By rotating, the connecting cylinder 53 and the baffle 54 can be rotated to adjust the shading angle. A gear 55 located behind the connecting cylinder 53 is fixedly installed on the outside of the support rod 52. A limiting frame 56 located below the gear 55 is fixedly installed on the top of the base plate 310. A rack 57 that meshes with the bottom of the gear 55 is slidably installed on the inner side of the limiting frame 56 to provide a track for the sliding of the rack 57. A groove is opened on its inner bottom wall to cooperate with a U-shaped rod 58 to fix the position of the rack 57. A U-shaped rod 58 extending to its bottom is slidably installed on the top of the rack 57. A pull ring 59 is fixedly installed on the top of the U-shaped rod 58.

[0042] The inner bottom wall of the limiting frame 56 is provided with a slot that matches the U-shaped rod 58. The inner side of the rack 57 is provided with a mounting hole that matches the U-shaped rod 58. The outer side of the pull ring 59 is covered with a sponge sleeve to facilitate the operator to pull the U-shaped rod 58. The sponge sleeve on its outer side increases the comfort of operation.

[0043] The support mechanism 6 includes a crossbar 601. The crossbar 601 is fixedly installed between the front and rear sides of the inner wall of the outer box 1. A rotating cylinder 602 is rotatably connected to the outer side of the crossbar 601, which drives the strip 603 to rotate, making it easy to adjust the angle of the strip 603. The strip 603 is fixedly installed on the right side of the rotating cylinder 602. A mounting hole 604 is opened on the inner side of the strip 603. A fixing cylinder 605 is fixedly installed on the inner wall of the mounting hole 604 near the bottom plate 310. A circular plate 606 is slidably installed on the inner side of the fixing cylinder 605. A pull rod 607 extending to the outside of the strip 603 is fixedly installed on one side of the circular plate 606. A pull ring 608 is fixedly installed at one end of the pull rod 607. A locking rod 609 penetrating the fixing cylinder 605 and extending to the outside of the strip 603 is fixedly installed on the other side of the circular plate 606. A telescopic spring 610 fixedly connected to the inner wall of the fixing cylinder 605 and sleeved on the outside of the locking rod 609 is fixedly installed on one side of the circular plate 606. Its elasticity makes the locking rod 609 always maintain the tendency to move into the circular groove of the bottom plate 310, ensuring the fixation of the position of the strip 603.

[0044] The inner side of the strip 603 is provided with a through hole that matches the pull rod 607. The size of the through hole is connected to the inner wall of the mounting hole 604. The inner side of the strip 603 is provided with a circular through hole that matches the clamp rod 609. The circular through hole is connected to the inner wall of the mounting hole 604.

[0045] The cleaning mechanism 7 includes support rails 71. Support rails 71 are fixedly installed on both the front and rear sides of the inner wall of the protective cover 2 to provide a track for the sliding frame 72 to slide and ensure the stability of the sliding frame 72. The sliding frame 72 is slidably installed between the two support rails 71. A cleaning roller 73 extending to the bottom of the inner wall of the sliding frame 72 is slidably installed between the front and rear sides of the inner wall of the sliding frame 72. When the sliding frame 72 moves, it rolls on the top of the calculator 4 to clean the surface of the calculator 4. The cleaning roller 72 is in contact with the top of the calculator 4. A telescopic rod 74 fixedly connected to the inner top wall of the sliding frame 72 is fixedly installed on the top of the cleaning roller 73. A connecting spring 75 sleeved on the outside of the telescopic rod 74 is fixedly installed between the sliding frame 72 and the cleaning roller 73. Its elasticity keeps the cleaning roller 73 in close contact with the top of the calculator 4 to ensure the cleaning effect. Two vertical plates 76 extending to the top of the protective cover 2 are fixedly installed on the top of the sliding frame 72. A pull bar 77 is fixedly installed between the two vertical plates 76.

[0046] The inner top wall of the protective cover 2 has two strip holes, the size of which is adapted to the moving trajectory of the vertical plate 76. The outer side of the pull bar 77 is provided with an anti-slip sleeve to increase the friction during operation and prevent slippage. The front and rear sides of the sliding frame 72 are provided with grooves that are adapted to the support rail 71.

[0047] An accounting apparatus and method, comprising the following steps:

[0048] S1: Locate the locking mechanism on the back of the outer box 1 that connects to the protective cover 2, open it, and then rotate the protective cover 2 using the hinge to fully expose the opening on the inner top wall of the outer box 1 for subsequent operations and access to the internal items.

[0049] S2: Adjust the tilt angle of the calculator 4 as needed. First, adjust the angle of the base plate 310 using the handle 311, and then adjust the strip 603 to rotate to a suitable height under the support of the rotating cylinder 603 and the crossbar 601. Locate the pull ring 608 on the strip 603 and pull it outward. The pull ring 608 drives the pull rod 607 to move outward in the through hole of the strip 603. The circular plate 606 at one end of the pull rod 607 slides outward in the fixed cylinder 605. At the same time, the locking rod 609 on the other side of the circular plate 606 moves outward, and the telescopic spring 610 is stretched. When the strip 603 rotates to the appropriate position, release the pull ring 608. Under the elastic force of the telescopic spring 610, the circular plate 606 moves inward, driving the locking rod 609 to move inward until the locking rod 609 is engaged in the corresponding circular groove on the base plate 310, thereby fixing the position of the strip 603.

[0050] S3: When it is necessary to shade the calculator 4, pull the pull ring 59 upward. The pull ring 59 drives the U-shaped rod 58 to slide upward in the rack 57. When the bottom of the U-shaped rod 58 disengages from the slot on the inner bottom wall of the limiting frame 56, the pull ring 59 can be pushed back and forth. The pull ring 59 drives the rack 57 to slide in the limiting frame 56. Since the rack 57 meshes with the bottom of the gear 55, the movement of the rack 57 will drive the gear 55 to rotate. The gear 55 is fixed on the support rod 52, so the support rod 52 will rotate accordingly. The connecting cylinder 53 and the baffle 54 on the outside of the support rod 52 will also rotate accordingly. After rotating the baffle 54 to the appropriate shading position, push the U-shaped rod 58 downward so that its bottom is re-engaged into the corresponding slot on the inner bottom wall of the limiting frame 56, thereby fixing the position of the baffle 54, and then accounting can be performed.

[0051] S4: After the calculation is completed, when there is dust or stains on the surface of the calculator 4 that need to be cleaned, first reset the sunshade mechanism 5, support mechanism 6 and fixing mechanism 3, close the protective cover 2, find the pull bar 77 at the top of the protective cover 2, hold the anti-slip sleeve on the pull bar 77, and push the pull bar 77 back and forth. The pull bar 77 drives the sliding frame 72 to slide back and forth between the two support rails 71 through the two vertical plates 76. The cleaning roller 73 in the sliding frame 72 is always in close contact with the top of the calculator 4 under the action of the telescopic rod 74 and the connecting spring 75. As the sliding frame 72 moves, the cleaning roller 73 rolls on the top of the calculator 4, thereby cleaning the surface of the calculator 4. After cleaning, the whole device can be stored and carried easily through the carrying handle.

[0052] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0053] In summary, this accounting device, through the setting of a fixing mechanism 3, a sunshade mechanism 5, and a support mechanism 6, utilizes the elasticity of a fixing spring 308 to cause the pull rod 306 to drive the limiting block 307 to clamp and fix the calculator 4. When it is necessary to place the calculator 4, pull the strip plate 309. The strip plate 309 drives the two pull rods 306 to move to the left. The pull rods 306 drive the limiting block 307 to compress the fixing spring 308. At this time, the calculator 4 is placed into the base 302, so that the calculator 4 is in contact with the bottom of the stop bar 303. Then, release the strip plate 309, the fixing spring 308 returns to its original position, and push the limiting block 307 to move to the right until the limiting block 307 is in contact with the outside of the calculator 4, thus fixing the calculator 4. To remove the calculator 4, simply reverse the above steps. The angle of the baffle 54 is adjusted by the meshing transmission of the rack 57 and the gear 55. When shading is needed, pull the ring 59 to move the U-shaped rod 58 upward. The U-shaped rod 58 disengages from the slot in the inner bottom wall of the limiting frame 56. At this time, the rack 57 can be pushed or pulled to slide within the limiting frame 56. The rack 57 drives the gear 55 to rotate, and the gear 55 drives the support rod 52 to rotate. The support rod 52 drives the baffle 54 to rotate through the connecting cylinder 53, thereby adjusting the angle of the baffle 54 to achieve the shading effect. After adjustment, the U-shaped rod 58 is moved downward to insert into the slot in the inner bottom wall of the limiting frame 56, fixing the position of the rack 57 and thus fixing the angle of the baffle 54. The elasticity of the telescopic spring 610 is used to make the locking rod 609 engage with the circular groove on the base plate 310. The mechanism works in conjunction with the control ring 608 to fix and adjust the angle of the strip 603. When the angle of the strip 603 needs to be adjusted, the pull ring 608 is pulled. The pull ring 608 drives the circular plate 606 to slide within the fixed cylinder 605 via the pull rod 607. The circular plate 606 compresses the telescopic spring 610, simultaneously moving the locking rod 609 into the mounting hole 604, causing the locking rod 609 to disengage from the circular groove on the base plate 310. At this point, the strip 603 can be rotated. The strip 603 rotates on the crossbar 601 via the rotating cylinder 602. After adjusting to the appropriate angle, the pull ring 608 is released, the telescopic spring 610 returns to its original position, and the circular plate 606 moves outward. The circular plate 606 drives the locking rod 609 to insert into the corresponding circular groove on the base plate 310, fixing the angle of the strip 603 and facilitating easy adjustment of the operating angle. The purpose of this dustproof structure is to facilitate the use of the device by setting up the sunshade mechanism 5. The cleaning mechanism 7, relying on the elasticity of the connecting spring 75, ensures that the cleaning roller 73 remains in contact with the top of the calculator 4. The sliding frame 72 slides on the support rail 71, driving the cleaning roller 73 to clean the surface of the calculator 4. When cleaning the surface of the calculator 4 is required, the pull bar 77 is grasped and pulled, causing the vertical plate 76 to move. The vertical plate 76 then causes the sliding frame 72 to slide on the support rail 71, and the sliding frame 72 causes the cleaning roller 73 to roll on the top of the calculator 4. Under the action of the connecting spring 75, the cleaning roller 73 always remains in close contact with the top of the calculator 4, thereby cleaning away dust and other debris from the surface of the calculator 4, achieving the purpose of the dustproof structure.This solves the problem of devices being flat and unable to be adjusted for different viewing angles. This caused glare on the screen under bright light or sunlight, making it difficult for operators to see the displayed data and leading to calculation errors. Furthermore, the lack of a dustproof structure resulted in dust accumulation on the surface over time, hindering the device's operation.
