Detailed implementation manners

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0036] Referring to Figures 1-9 , the present invention provides a technical solution: an accounting audit verification device, including a verification board 1. The top of the verification board 1 is open. A verification mechanism is provided on the verification board 1. The verification mechanism includes a chute 201, a rotating plate 203, a first marking needle 206, and a first lead screw 210. Two chutes 201 are provided, and the two chutes 201 are symmetrically provided at the top of the verification board 1. A sliding plate 202 is slidably sleeved inside the chute 201. Two rotating plates 203 are provided, and the rotating plates 203 are rotatably installed on the opposite sides of the two sliding plates 202. Two first limiting rods 204 and two second limiting rods 205 are fixedly installed between the two rotating plates 203. The first marking needle 206 is slidably sleeved between the two first limiting rods 204. A second marking needle 207 is slidably sleeved between the two second limiting rods 205. A first gear 208 and a second gear 209 are rotatably installed on one side of one of the rotating plates 203 close to the first marking needle 206. The first lead screw 210 is fixedly installed on the right side of the first gear 208. The first lead screw 210 is threadedly sleeved inside the first marking needle 206. A second lead screw 211 is fixedly installed on the right side of the second gear 209. The second lead screw 211 is threadedly sleeved inside the second marking needle 207. The bottom wall of the verification board 1 is made of a magnetic material. A magnetic attraction block 218 is provided on the top of the verification board 1, and the two are magnetically attracted to each other. By setting the marking mechanism, the content to be verified is placed above the verification board 1 and its four corners are fixed by the magnetic attraction block 218. When the first gear 208 rotates, it drives the first lead screw 210 to rotate. Under the threaded connection between the first lead screw 210 and the first marking needle 206 and the limiting cooperation of the first limiting rod 204, the first marking needle 206 gradually moves from the left side to the right side of the first limiting rod 204, enabling the user to follow the guidance of the first marking needle 206 for verification, thus assisting the user to concentrate attention. At the same time, the second gear 209 rotates. Similarly, the second marking needle 207 gradually moves from the rightmost side to the leftmost side. When the user finishes reading a line of content, the rotating plate 203 is flipped 180 degrees, and at the same time, the sliding plate 202 moves inside the chute 201. At this time, the user gradually verifies from left to right according to the guidance of the second marking needle 207. Repeating this way, the user's attention is more concentrated during verification and it is not easy to make mistakes.

[0037] Refer to Figures 1-9 , the thread directions of the first lead screw 210 and the second lead screw 211 are opposite, the first marking needle 206 and the second marking needle 207 are arranged in a mirror image. A third gear 212 is rotatably installed on one side of one turntable 203 close to the first marking needle 206. The first gear 208 and the second gear 209 are both meshed and connected with the third gear 212. A first handwheel 213 is rotatably installed on the left side of one slide plate 202. A connecting rod 214 is fixedly installed on the right side of the first handwheel 213. The right side of the connecting rod 214 is fixedly connected with the left side of the third gear 212. By setting the third gear 212, when the user rotates the first handwheel 213, the third gear 212 is driven to rotate through the connecting rod 214. Since the first gear 208 and the second gear 209 are both meshed and connected with the third gear 212, and the first gear 208 and the second gear 209 are respectively located on both sides of the third gear 212, the first gear 208 and the second gear 209 rotate in the same direction at the same time. Since the thread directions of the first lead screw 210 and the second lead screw 211 are opposite, when the first lead screw 210 and the second lead screw 211 rotate in the same direction at the same time, the moving trajectories of the first marking needle 206 and the second marking needle 207 are opposite;

[0038] Refer to Figures 1-9 , a third lead screw 215 is rotatably installed inside one of the chutes 201, and a slide bar 216 is fixedly installed inside the other chute 201. The third lead screw 215 and the slide bar 216 are respectively sleeved inside the two slide plates 202. A second handwheel 217 is fixedly installed on the rear side of the third lead screw 215. By setting the third lead screw 215, when the user rotates the second handwheel 217, the third lead screw 215 is driven to rotate. Through the threaded connection between the third lead screw 215 and one of the slide plates 202, the sliding connection between the other slide plate 202 and the slide bar 216, and the cooperation of the chute 201, the two slide plates 202 move simultaneously to assist the user in checking the content of the next line;

[0039] Refer to Figures 1-9, a toothed plate 219 is fixedly installed at the bottom of the check plate 1. A fourth gear 220 is rotatably installed on the right side of one of the sliding plates 202. The fourth gear 220 is meshed and connected with the toothed plate 219. A first transmission rod 221 is fixedly installed on the left side of the fourth gear 220. A second transmission rod 222 is fixedly installed on the left side of one of the rotating plates 203. The second transmission rod 222 is hollow. The second transmission rod 222 and the connecting rod 214 are coaxially arranged. Rotating wheels are fixedly sleeved on the surfaces of the first transmission rod 221 and the second transmission rod 222. A transmission belt 223 is sleeved between the first transmission rod 221 and the second transmission rod 222 through the rotating wheels. By setting the toothed plate 219, when the two sliding plates 202 move, the fourth gear 220 is driven to move. Since the fourth gear 220 is meshed and connected with the toothed plate 219, the fourth gear 220 drives the first transmission rod 221 to rotate. Through the cooperation of the transmission belt 223, the second transmission rod 222 is driven to rotate, so that the rotating plate 203 rotates 180 degrees, and the relative positions of the first marking needle 206 and the second marking needle 207 are interchanged;

[0040] Refer to Figures 1-9 , a check mechanism is arranged between the two rotating plates 203. The check mechanism includes a follower rod 301. The follower rod 301 is fixedly installed on the right side of the fourth gear 220. A ratchet wheel 302 is rotatably installed on the left side of one of the rotating plates 203. The ratchet wheel 302 is fixedly sleeved on the surface of the follower rod 301. A fixed buckle 303 is fixedly installed on the left side of one of the rotating plates 203. A ratchet pawl 304 is rotatably sleeved on the surface of the fixed buckle 303. A torsion spring 305 is installed between the fixed buckle 303 and the ratchet pawl 304. By setting the check mechanism, when the fourth gear 220 rotates, the ratchet wheel 302 is driven to rotate through the follower rod 301. After the ratchet teeth on the ratchet wheel 302 squeeze the ratchet pawl 304, the ratchet pawl 304 rotates and the torsion spring 305 accumulates elastic potential energy. Until the ratchet teeth and the ratchet pawl 304 are misaligned, the ratchet pawl 304 returns to its original position through the resilience of the torsion spring 305. Repeating like this, when the ratchet wheel 302 attempts to rotate in the reverse direction, the ratchet wheel 302 cannot rotate in the reverse direction due to the abutment between the ratchet teeth on the ratchet wheel 302 and the ratchet pawl 304, thereby preventing the sliding plate 202 from returning to the position of the previous row;

[0041] Refer to Figures 1-9, an angle adjustment mechanism is provided at the bottom of the check board 1, and the angle adjustment mechanism includes a support box 401, the support box 401 is rotatably mounted on the surface of the check board 1 through a hinge, the top of the support box 401 is open, and a fixed block 402 is fixedly installed at the bottom of the check board 1, and a through slot 403 is provided on both sides of the support box 401. A driving rod 404 is slidably sleeved inside the through slot 403, and a driving shaft 405 is fixedly installed between the two driving rods 404. A rotating rod 406 is provided between the driving shaft 405 and the fixed block 402, and one end of the rotating rod 406 is rotatably sleeved inside the fixed block 402, and the other end of the rotating rod 406 is rotatably sleeved inside the fixed block 402. The surface of the driving shaft 405 is provided with an angle adjustment mechanism. When the user needs to adjust the angle of the check plate 1, the user pulls the driving rods 404 on both sides forward, so that the driving rods 404 drive the driving shaft 405 to move forward. The driving shaft 405 squeezes the rotating rod 406, and the rotating rod 406, the driving shaft 405 and the fixed block 402 are rotatably connected. When the rotating rod 406 rotates, the check plate 1 rotates with the hinge as the center of the circle, so that the angle of the check plate 1 can be adjusted. The user can adjust the check plate 1 to a suitable angle according to his own needs, which helps to improve the user's comfort when using it.

[0042] Reference Figures 1-9 A moving cavity 407 is provided at the bottom of the driving rod 404, and a wedge 408 is provided inside the sliding sleeve of the moving cavity 407. A spring 409 is fixedly installed at the bottom of the inner wall of the moving cavity 407, and the other end of the spring 409 is fixedly connected to the top of the wedge 408. A fixing bar 410 is fixedly installed at the top of the inner wall of the support box 401, and a plurality of locking grooves 411 are provided on the top of the fixing bar 410. A yielding groove 412 is provided on the side of the moving cavity 407 away from the driving shaft 405, and an unlocking rod 413 is provided inside the sliding sleeve of the yielding groove 412. The unlocking rod 413 is fixedly connected to the wedge 408. By setting the wedge 408, when the driving rod 404 moves forward, the wedge 408 is driven to move forward until it reaches Above the first locking groove 411, the wedge block 408 is rebounded into the interior of the first locking groove 411 by the rebound force of the spring 409. At this time, the interior of the locking groove 411 is against the flat side of the wedge block 408, so that the check plate 1 will not fall back to its original position due to its own gravity. If the user needs to adjust the angle of the check plate 1, the wedge block 408 continues to be moved forward. The wedge block 408 is squeezed by the inner wall of the first locking groove 411 and retracts into the interior of the moving groove until it reaches the next locking groove 411. This is repeated. When the check plate 1 needs to be placed back into the interior of the support box 401, the unlocking rod 413 is moved upward to drive the wedge block 408 to move upward, thereby releasing the lock of the check plate 1.

[0043] Specifically, the working process or principle of this accounting audit verification device is as follows: When in use, place the content to be verified above the verification board 1 and fix its four corners through the magnetic attraction blocks 218. When the user rotates the first handwheel 213, the third gear 212 is driven to rotate through the connecting rod 214. Since both the first gear 208 and the second gear 209 are meshed with the third gear 212, and the first gear 208 and the second gear 209 are respectively located on both sides of the third gear 212, the first gear 208 and the second gear 209 rotate simultaneously in the same direction. When the first gear 208 rotates, it drives the first lead screw 210 to rotate. Through the threaded connection between the first lead screw 210 and the first marking needle 206, and the limiting cooperation of the first limiting rod 204, the first marking needle 206 gradually moves from the left side of the first limiting rod 204 to the right side, enabling the user to perform verification following the guidance of the first marking needle 206, thus assisting the user to concentrate. At the same time, the second gear 209 rotates, and similarly, the second marking needle 207 gradually moves from the rightmost side to the leftmost side. When the user rotates the second handwheel 217, it drives the third lead screw 215 to rotate. Through the threaded connection between the third lead screw 215 and one of the sliding plates 202, the sliding connection between the other sliding plate 202 and the sliding rod 216, and the cooperation of the sliding groove 201, the two sliding plates 202 move simultaneously. When the two sliding plates 202 move, they drive the fourth gear 220 to move. Since the fourth gear 220 is meshed with the toothed plate 219, the fourth gear 220 drives the first transmission rod 221 to rotate. Through the cooperation of the transmission belt 223, the second transmission rod 222 is driven to rotate, thereby causing the rotating plate 203 to rotate 180 degrees, making the relative positions of the first marking needle 206 and the second marking needle 207 swapped. At this time, the user gradually performs verification from left to right following the guidance of the second marking needle 207. Repeating this process, when the user needs to adjust the angle of the verification board 1, the user pulls the driving rods 404 on both sides forward, causing the driving rods 404 to drive the driving shaft 405 to move forward. Through the extrusion of the driving shaft 405 on the rotating rod 406, and the rotational connection between the rotating rod 406, the driving shaft 405, and the fixed block 402, while the rotating rod 406 rotates, the verification board 1 rotates with the hinge as the center, thereby enabling the angle of the verification board 1 to be adjusted. When the driving rod 404 moves forward, it drives the wedge block 408 to move forward until it reaches above the first locking groove 411. The wedge block 408 pops into the interior of the first locking groove 411 through the resilience of the spring 409. At this time, the flat side of the wedge block 408 is abutted against the interior of the locking groove 411, preventing the verification board 1 from falling back to its original position due to its own gravity. If the user needs to adjust the angle of the verification board 1, continue to move the wedge block 408 forward. After being squeezed by the inner wall of the first locking groove 411, the wedge block 408 retracts into the interior of the moving groove until it reaches the next locking groove 411,Repeat this process. When it is necessary to place the verification plate 1 back inside the support box 401, moving the unlocking lever 413 upward can drive the wedge block 408 upward, thereby unlocking the verification plate 1.
