Abstract
Description
Technical Field
[0001] This utility model relates to the field of auditing technology, specifically an auxiliary device for auditing. Background Technology
[0002] Auditing refers to an independent economic oversight activity conducted by a specialized agency in accordance with the law to review the major projects and financial revenues and expenditures of governments at all levels, financial institutions, and enterprises before and after the fact. Auditing work requires stamping a large number of paper documents, and currently, most of these stamping tasks are done manually by auditors, which can easily lead to wrist fatigue among staff.
[0003] A search revealed that patent CN221698310U discloses an improved financial auxiliary auditing device. This device utilizes a fixed card holder, rubber pads installed on the inner wall of the fixed card holder, a compression screw, a compression plate, and rubber pads installed on the side of the compression plate to secure different types of stamps, thus improving the device's adaptability. Furthermore, by using an electric hydraulic push rod, the stamp can be driven downwards for stamping, facilitating the device's use.
[0004] While the above solution can use an electric hydraulic push rod to move the stamp up and down to complete the stamping action, it lacks a reference, making it inconvenient for staff to accurately place the stamping position on the document directly below the stamp. Furthermore, when using traditional stamps (non-returnable stamps or flip-up stamps), since the stamp itself cannot store ink, after each few stamps, the ink pad needs to be manually placed on the stamp surface to pick up the ink, making it cumbersome to use and requiring improvement. Utility Model Content
[0005] The purpose of this invention is to provide an auxiliary device for auditing to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An auditing auxiliary device includes a base, a housing fixedly connected to the top of the base via a column, a vertical rod connected to the housing via a parallelogram linkage mechanism, a stamp detachably connected to the lower end of the vertical rod, a speed-reducing stepper motor for driving the parallelogram linkage mechanism fixedly installed on the outer wall of the housing, a switch installed on the outer wall of the housing, a laser pointer inserted through the bottom of the housing, an ink pad embedded in the top of the base via a groove, a support block movably inserted through the top of the base via a movable slot, a spring provided at the bottom of the support block, the ink pad and the support block being located on the movement path of the stamp, and the light spot emitted by the laser pointer being located at the center of the top surface of the support block.
[0008] As a further embodiment of this utility model: the parallelogram linkage mechanism includes a rotating shaft rotatably installed inside the housing, and a connecting rod is fixedly sleeved on one end of each of the two rotating shafts after extending out of the housing. The ends of the two connecting rods away from the rotating shafts are rotatably connected to a horizontal bar. The top end of the vertical bar is fixedly connected to the horizontal bar. Both rotating shafts are drively connected to the output shaft of the deceleration stepper motor.
[0009] As a further embodiment of this utility model: the rotating shaft is fixedly sleeved with gears on the outer wall inside the housing; a slider is slidably installed inside the housing; a rack is fixedly installed at the bottom of the slider; all gears mesh with the rack; the output shaft of the deceleration stepper motor passes through the housing and is fixedly connected to a lead screw; the lead screw is rotatably connected to the housing through a bearing seat; a lead screw nut is fitted onto the outer wall of the lead screw; and the lead screw nut is fixedly connected to the slider.
[0010] As a further embodiment of this utility model: both outer walls of the slider are provided with grooves, and guide rods are slidably inserted in the grooves, and the guide rods are fixedly connected to the inner wall of the housing.
[0011] As a further embodiment of this utility model: a connecting sleeve is fixedly connected to the lower end of the vertical rod, the top end of the seal is located inside the connecting sleeve, and a hand-tightening bolt is installed on the outer wall of the connecting sleeve through a threaded hole.
[0012] As a further improvement of this utility model: a protective cover is fixedly installed on the outer wall of the housing, and the tops of the connecting rod, the horizontal rod and the vertical rod are all located inside the protective cover.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention features a stamp driven by a parallelogram linkage mechanism, enabling the stamp to reciprocate in an arc between the inkpad and the support block. Therefore, when stamping, simply place the document on the support block, align the area to be stamped with the laser pointer's spot, and then activate the speed-reducing stepper motor to move the stamp onto the document and stamp the area. Press the support block down to utilize the spring force to ensure tight contact between the stamp and the document, thus guaranteeing a good stamping effect. Afterward, the stamp moves in the reverse direction and presses against the inkpad to replenish ink, eliminating the need for manual ink application and making it more convenient to use.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 In this embodiment of the present invention, an auditing auxiliary device includes a base 1. A housing 3 is fixedly connected to the top of the base 1 via a column 2. A vertical rod 7 is connected to the housing 3 via a parallelogram linkage mechanism. A stamp 10 is detachably connected to the lower end of the vertical rod 7. A deceleration stepper motor 16 for driving the parallelogram linkage mechanism is fixedly installed on the outer wall of the housing 3. A switch 19 is installed on the outer wall of the housing 3. A laser pointer 25 is installed through the bottom of the housing 3. An ink pad 21 is embedded in the top of the base 1 via a groove. A support block 23 is movably installed through the top of the base 1 via a movable slot 22. A spring 24 is provided at the bottom of the support block 23. The ink pad 21 and the support block 23 are both located on the moving path of the stamp 10, and the light spot emitted by the laser pointer 25 is located at the center of the top surface of the support block 23.
[0023] Furthermore, the parallelogram linkage mechanism includes a rotating shaft 4 rotatably installed inside the housing 3. One end of each of the two rotating shafts 4 extends out of the housing 3 and is fixedly sleeved with a connecting rod 5. The ends of the two connecting rods 5 away from the rotating shafts 4 are rotatably connected to a horizontal rod 6. The top end of the vertical rod 7 is fixedly connected to the horizontal rod 6. Both rotating shafts 4 are drively connected to the output shaft of the deceleration stepper motor 16.
[0024] By adopting the above-described scheme, this utility model activates the stepper motor 16 to drive the two rotating shafts 4 of the parallelogram linkage mechanism to rotate at the same speed and in the same direction. This causes the horizontal bar 6, the vertical bar 7, and the stamp 10 to move along an arc-shaped trajectory. The ink pad 21 and the support block 23 are both located on this arc-shaped trajectory. Therefore, when it is necessary to stamp a document during auditing, simply place the document on the support block 23 and align the area to be stamped with the light spot emitted by the laser pointer 25. Then, by activating the stepper motor 16, the stamp 10 can be moved onto the document for stamping. The support block 23 is then pressed down to ensure that the stamp 10 is in close contact with the document using the elasticity of the spring 24, thus ensuring the stamping effect. Afterward, the stamp 10 is driven to move in the opposite direction to press it onto the ink pad 21 to pick up ink. This eliminates the need for manual ink dipping, making it more convenient to use.
[0025] Specific combination Figure 3 In one embodiment of this utility model, the rotating shaft 4 is fixedly sleeved with a gear 11 on the outer wall inside the housing 3. A slider 12 is slidably installed inside the housing 3. A rack 15 is fixedly installed at the bottom of the slider 12. The gear 11 meshes with the rack 15. The output shaft of the deceleration stepper motor 16 passes through the housing 3 and is fixedly connected to a lead screw 17. The lead screw 17 is rotatably connected to the housing 3 through a bearing seat. A lead screw nut 18 is fitted onto the outer wall of the lead screw 17. The lead screw 17 is a reciprocating lead screw so that the lead screw nut 18 can make reciprocating linear motion within a certain range without changing the direction of rotation of the deceleration stepper motor 16. The lead screw nut 18 is fixedly connected to the slider 12.
[0026] By starting the deceleration stepper motor 16, the lead screw 17 can be driven to rotate, thereby using the cooperation between the lead screw 17 and the lead screw nut 18 to drive the slider 12 to perform reciprocating linear motion. In turn, the cooperation between the rack 15 and the gear 11 drives the two rotating shafts 4 to perform reciprocating rotational motion within a certain angle range. The parallelogram linkage mechanism is used to realize the reciprocating arc motion of the stamp 10 between the ink pad 21 and the support block 23.
[0027] Specific combination Figure 3 In one embodiment of the present invention, the outer walls on both sides of the slider 12 are provided with grooves 14, and a guide rod 13 is slidably inserted in the grooves 14. The guide rod 13 is fixedly connected to the inner wall of the housing 3.
[0028] The cooperation between the slide groove 14 and the guide rod 13 ensures the stability of the slider 12 sliding within the housing 3.
[0029] Specific combination Figure 1In one embodiment of this utility model, a connecting sleeve 8 is fixedly connected to the lower end of the vertical rod 7, and the top end of the seal 10 is located inside the connecting sleeve 8. A hand-tightening bolt 9 is installed through a threaded hole on the outer wall of the connecting sleeve 8. With the setting of the connecting sleeve 8 and the hand-tightening bolt 9, the seal 10 can be fixed simply by inserting the top end of the seal 10 into the connecting sleeve 8 and tightening the hand-tightening bolt 9. The operation is simple and convenient.
[0030] Specific combination Figure 1 and Figure 2 In one embodiment of this utility model, a protective cover 20 is fixedly installed on the outer wall of the housing 3, and the top ends of the connecting rod 5, the horizontal rod 6 and the vertical rod 7 are all located inside the protective cover 20 to improve the safety of equipment operation.
