Description

Technical Field

[0001] This invention relates to the field of office technology, and more specifically to a corporate credit rating device. Background Technology

[0002] Corporate credit rating, as a complete system, includes elements and indicators of credit rating, credit rating levels and standards, credit rating methods and models, etc. Among them, credit rating indicators and credit rating methods are the two most core components of the credit rating system, and also the two most closely related and profoundly influential components.

[0003] In the prior art, such as the enterprise credit rating device described in Chinese Patent No. CN214396163U, a desktop is provided. A mounting groove is formed on the top of the desktop, and the rating device body is movably mounted on the top of the mounting groove. A fixing block is fixedly connected to the side of the rating device body, and a slot is formed on the side of the fixing block. A writing pen is movably mounted on the inner wall of the slot, and a traction wire is fixedly mounted to the end of the writing pen. A left fixing plate is fixedly connected to the top of the desktop. In this enterprise credit rating device, the rating device body is placed on the top of the desktop through the mounting groove. A slider moves within a groove to push the right fixing plate towards the rating device body. The left and right fixing plates, a limiting spring, and a rubber limiting plate provide limiting and protective contact for the rating device body, effectively ensuring that the rating device will not fall off during long-term use and providing a certain degree of safety for the user.

[0004] However, while the aforementioned patents have the advantages mentioned above, their disadvantages are that, when using them, the pen still needs to be tied to the platform via a tether. The tether limits the pen's writing range and writing experience. The platform itself has a fixed structure, making it difficult to process a large number of documents simultaneously. When rating enterprises, many people are needed to analyze a large number of documents at the same time. The aforementioned patents have certain limitations and prerequisites for use, making it difficult to achieve ratings for large enterprises. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: a corporate credit rating device, comprising a base plate, a top plate, a magnetic suction device, and a magnetic suction groove. The magnetic suction groove is formed in the wall of the top plate. The lower surface of the magnetic suction device is magnetically attracted to the upper surface of the top plate. The entire device is folded, and personnel perform risk assessment and calculation on the upper surfaces of the base plate and the top plate. A pen is inserted inside the magnetic suction device and placed inside the magnetic suction groove along with the magnetic suction device. When the desktop area needs to be expanded, the base plate and the top plate are stretched to the left and right. A protruding strip is fixedly connected to the upper surface of the base plate. An air inlet pipe is provided at the bottom of the base plate. A U-shaped tube is fixedly connected to the right end of the air inlet pipe. A movable plate is provided at the top of the U-shaped tube. A limit block is fixedly connected to the outer surface of the left side of the movable plate, and a sliding rod is provided on the right side of the limit block.

[0006] The magnetic suction device includes a pen holder, a counterweight ring slidably connected to the inner surface of the pen holder, a nut at the bottom of the counterweight ring, an elliptical block at the bottom of the nut, and a rubber sleeve at the bottom of the elliptical block. Under the constraint of the sliding rod, the two are kept apart. Three movable plates are provided at the bottom of the top plate, each corresponding to a U-shaped tube. The device can expand outwards in three positions from left to right when folded and combined. An anti-slip ring is fixedly connected to the outer surface of the rubber sleeve, and a suction cup is provided at the bottom of the anti-slip ring. A ball head is rotatably connected to the inner surface of the suction cup, and a magnetic suction piece is fixedly connected to the outer surface of the bottom of the ball head.

[0007] Preferably, the left end of the slide rod is fixedly connected to the outer surface of the right side of the base plate, and the upper surface of the base plate is slidably connected to the lower surface of the top plate. When the inclined opening at the bottom left side of the top plate passes the outer surface of the right side of the leftmost movable plate, the compression spring pushes the piston to slide to the right along the inner surface of the gas cylinder. The high-pressure air inside the gas cylinder is injected into the U-shaped tube through the air inlet pipe. The inner surface of the base plate is slidably connected to the outer surface of the slide rod, and the outer surfaces of the limiting block and the movable plate are slidably connected to the inner surface of the base plate.

[0008] Preferably, the inner surface of the pen holder is movably connected to the outer surface of the elliptical block, the outer surface of the pen holder is threadedly connected to the inner surface of the nut, the push rod pushes the movable plate upward until the upper surface of the movable plate is horizontally aligned with the upper surface of the top plate, as the top plate continues to move to the right, the outer surface of the left side of the top plate passes over the upper surface of the protrusion, the pressure on the right side of the slider decreases, the outer surface of the pen holder is slidably connected to the inner surface of the rubber sleeve, the bottom end of the pen holder is fixedly connected to the upper surface of the suction cup, and the lower surface of the suction cup is in contact with the upper surface of the top plate.

[0009] Preferably, a piston is provided on the left side of the air intake pipe, and a graduated ring is provided in the wall of the piston. A compression spring is provided on the right side of the graduated ring. The spring pushes the slider to the right through a horizontal rod, so that the lower surface of the slider slides along the upper surface of the convex strip. During this process, as the slider moves to the right, the folding plate is pulled to the right, and the downward folding plate gradually becomes horizontal. A gas cylinder is fixedly connected to the left end of the compression spring.

[0010] Preferably, the outer surface of the piston is fixedly connected to the right end of the compression spring. Since the bottom corner of the folding plate initially abuts against the top of the support tube, the downward pressure forces the middle of the support tube to be sealed, and the high-pressure gas inside the airbag is isolated. As the folding plate is stretched, the inside of the support tube is connected. With the assistance of the spring sheet, the gas inside the airbag is injected into the inside of the support tube. The outer surface of the piston is slidably connected to the inner surface of the gas cylinder, and the right end of the gas cylinder is fixedly connected to the left end of the air inlet pipe.

[0011] Preferably, a top rod is slidably connected to the inner surface of the U-shaped tube, a horizontal rod is provided at the top of the top rod, and a storage spring is provided outside the horizontal rod. The support tube is taut and abuts against the bottom of the folding plate. The folding plate eliminates the gap on the left side when the slider slides to the right. The folding plate and the slider eliminate the gap at the top of the protrusion. Together with the spring-loaded movable plate, they ensure that the gap between the bottom plate and the top plate is not too large when stretched, ensuring that the writing surface is flat. The right end of the storage spring is fixedly connected to the slider.

[0012] Preferably, the outer surface of the top rod is slidably connected to the inner surface of the U-shaped tube, and the top end of the top rod is fixedly connected to the lower surface of the movable plate. The top end of the pen that meets the maximum inner diameter of the pen holder is inserted into the pen holder. By rotating the nut, under the action of the threaded connection, the bevel at the bottom of the nut contacts and presses against the outer surface of the elliptical block. The elliptical block rotates at a certain angle and tilts. The tilted elliptical block abuts against and jams the outer surface of the pen. Then, the rubber sleeve slides upward so that the rubber sleeve is inserted into the annular groove. The upper surface of the movable plate is slidably connected to the lower surface of the top plate, and the left end of the energy storage spring is fixedly connected to the inner surface of the movable plate.

[0013] Preferably, a folding plate is fixedly connected to the outer surface of the left side of the slider, and an anti-slip ring prevents the pen holder from slipping on the hand. Since the pen tip is covered by a magnetic suction device, the tip is relatively heavy. To improve adaptability during writing, the counterweight ring can be removed to avoid top-heavy writing. When writing, the pen tip faces upward, and the magnetic suction piece flips into the inside of the suction cup under the action of gravity, causing the ball head to rotate. A support tube is provided at the bottom of the folding plate, and air bladders are fixedly connected to both ends of the support tube. When not in use, the magnetic suction device and the pen can be placed horizontally or vertically on the table, with the magnetic suction piece partially exposed to provide magnetic attraction and prevent the pen from rolling off. The suction cup can also be attached to the table to prevent it from falling. If the pen and the magnetic suction device are accidentally dropped, a spring is fixedly connected to the inner surface of the air bladder.

[0014] Preferably, the outer surface of the left side of the folding plate is rotatably connected to the inner surface of the movable plate, and the lower surface of the folding plate is in contact with the upper surface of the support tube. During the fall, because the mass of the pen tip is greater than the mass of the pen nib, the pen will automatically flip in the air so that the nib faces upward. At the moment of landing, the suction cup can play a buffering role, so the pen suffers less damage. The pen can move freely while preventing it from falling. If it does fall, it can automatically flip during the fall. At the same time, the pen holder can quickly replace different sizes of pens, and the device has strong versatility. The inner surface of the movable plate is fixedly connected to the outer surface of the airbag.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention features a base plate and a top plate. When the two plates are close together, the entire device folds. Personnel perform risk assessments and calculations on the upper surfaces of the base and top plates. A pen is inserted inside the magnetic suction device and placed inside the magnetic suction slot along with the device. When the desktop area needs to be expanded, the base and top plates are pulled left and right, moving away from each other under the constraint of a sliding rod. The bottom of the top plate has three movable plates, each corresponding to a U-shaped tube. The device can expand outwards in three increments while folded. From left to right, when the slanted opening at the bottom left side of the top plate passes the outer surface of the right side of the leftmost movable plate, the compression spring pushes the piston to slide to the right along the inner surface of the gas cylinder. High-pressure air from inside the gas cylinder is injected into the U-shaped tube through the air inlet pipe. The push rod lifts the movable plate upwards until the upper surface of the movable plate is horizontally aligned with the upper surface of the top plate. As the top plate continues to move to the right, the outer surface of the left side of the top plate passes the convex... On the upper surface of the strip, the pressure on the right side of the slider decreases, and the storage spring pushes the slider to the right through the horizontal rod, causing the lower surface of the slider to slide along the upper surface of the convex strip. During this process, as the slider moves to the right, the folding plate is pulled to the right, and the downward-folding folding plate gradually becomes horizontal. Since the bottom corner of the folding plate initially abuts against the top of the support tube, the downward pressure forces the middle of the support tube to be sealed, isolating the high-pressure gas inside the airbag. As the folding plate stretches, the inside of the support tube becomes connected. With the assistance of the spring plate, the gas inside the airbag is injected into the inside of the support tube, the support tube straightens, and abuts against the bottom of the folding plate. The folding plate eliminates the gap on the left side when the slider slides to the right. The folding plate and slider eliminate the gap at the top of the convex strip. Together with the upper spring movable plate, they ensure that the gap between the bottom plate and the top plate is not too large when stretched, ensuring the flatness of the writing surface. This solves the problem of the traditional writing platform structure being fixed and having large gaps at the connection points when the structure is changed.

[0017] 2. This invention utilizes a magnetic suction device. When in use, the tip of a pen that meets the maximum inner diameter of the pen holder is inserted into the pen holder. Rotating the nut causes the beveled end of the nut to contact and press against the outer surface of the elliptical block due to the threaded connection. The elliptical block rotates at a certain angle, tilting and pressing against the outer surface of the pen. Then, the rubber sleeve slides upwards, engaging the annular groove. The anti-slip ring prevents the pen holder from slipping on the hand. Because the pen tip is covered by the magnetic suction device, it is relatively heavy. To improve writing comfort, the counterweight ring can be removed to avoid top-heavy writing. When writing, with the pen tip facing upwards, the magnetic suction plate flips under gravity into the suction cup, and the ball head rotates... When not in use, the magnetic device and pen can be placed horizontally or vertically on the table, with the magnetic plate exposed to provide magnetic attraction and prevent the pen from rolling off. Alternatively, the suction cup can be attached to the table to prevent it from falling. If the pen and magnetic device are accidentally dropped, the pen will automatically flip in mid-air, with the tip facing upwards, due to the greater mass of the pen tip than the pen nib. Upon impact, the suction cup provides cushioning, minimizing damage to the pen. The device allows for free movement while preventing drops. Even if it does fall, it will automatically flip during the fall. Furthermore, the pen holder allows for quick replacement of pens of different sizes, making the device highly versatile.

[0031] A piston 26 is located on the left side of the air intake pipe 20. A graduated ring 27 is formed in the wall of the piston 26. A compression spring 28 is located on the right side of the graduated ring 27. A gas cylinder 29 is fixedly connected to the left end of the compression spring 28. The outer surface of the piston 26 is fixedly connected to the right end of the compression spring 28, and the outer surface of the piston 26 is slidably connected to the inner surface of the gas cylinder 29. The right end of the gas cylinder 29 is fixedly connected to the left end of the air intake pipe 20.

[0032] A push rod 30 is slidably connected to the inner surface of the U-shaped tube 21. A horizontal rod 31 is provided at the top of the push rod 30, and a storage spring 32 is provided on the outside of the horizontal rod 31. A slider 33 is fixedly connected to the right end of the storage spring 32. The outer surface of the push rod 30 is slidably connected to the inner surface of the U-shaped tube 21, the top end of the push rod 30 is fixedly connected to the lower surface of the movable plate 22, the upper surface of the movable plate 22 is slidably connected to the lower surface of the top plate 2, and the left end of the storage spring 32 is fixedly connected to the inner surface of the movable plate 22.

[0033] A folding plate 34 is fixedly connected to the outer surface of the left side of the slider 33. A support tube 35 is provided at the bottom of the folding plate 34. Airbags 36 are fixedly connected to both ends of the support tube 35. Spring pieces 37 are fixedly connected to the inner surface of the airbags 36.

The lower surface of the folding plate 34 is in contact with the upper surface of the support tube 35. The inner surface of the movable plate 22 is fixedly connected to the outer surface of the airbags 36.

[0034] In use, when the base plate 1 and top plate 2 are close together, the entire device folds. Personnel perform risk assessments and calculations on the upper surfaces of the base plate 1 and top plate 2. A pen is inserted inside the magnetic suction device 3, and the pen is placed inside the magnetic suction slot 4 along with the magnetic suction device 3. When the desktop area needs to be expanded, the base plate 1 and top plate 2 are stretched to the left and right. Under the restriction of the sliding rod 24, the two move away from each other. The bottom of the top plate 2 is equipped with three movable plates 22, each corresponding to a U-shaped tube 21. The device can expand outwards by three levels based on the folded and combined structure. From left to right, when the slanted opening at the bottom left of the top plate 2 passes the outer surface of the right side of the leftmost movable plate 22, the compression spring 28 pushes the piston 26 to slide to the right along the inner surface of the gas cylinder 29. The high-pressure air inside the gas cylinder 29 is injected into the U-shaped tube 21 through the air inlet pipe 20. The push rod 30 pushes the movable plate 22 upwards until the upper surface of the movable plate 22 is horizontally aligned with the upper surface of the top plate 2. As the top plate 2 continues to move to the right, the top plate 2 moves to the left and right. As the outer surface of the slider 33 passes over the upper surface of the protrusion 25, the pressure on the right side of the slider 33 decreases. The storage spring 32 pushes the slider 33 to the right via the horizontal rod 31, causing the lower surface of the slider 33 to slide along the upper surface of the protrusion 25. During this process, as the slider 33 moves to the right, the folding plate 34 is pulled to the right, and the downward-folding folding plate 34 gradually becomes horizontal. Since the bottom corner of the folding plate 34 initially abuts against the top of the support tube 35, the downward pressure forces the middle of the support tube 35 to seal, and the high pressure inside the airbag 36... The gas is isolated. As the folding plate 34 is stretched, the inside of the support tube 35 is connected. With the assistance of the spring piece 37, the gas inside the airbag 36 is injected into the inside of the support tube 35. The support tube 35 straightens and abuts against the bottom of the folding plate 34. The folding plate 34 eliminates the gap on the left side when the slider 33 slides to the right. The folding plate 34 and the slider 33 eliminate the gap at the top of the protrusion 25. Together with the spring-loaded movable plate 22, they ensure that the gap between the bottom plate 1 and the top plate 2 is not too large when stretched, ensuring that the writing surface is flat.

[0035] Insert the tip of a pen that meets the maximum inner diameter of the pen holder 10 into the pen holder 10. Rotate the nut 12; under the action of the threaded connection, the beveled opening at the bottom of the nut 12 contacts and presses against the outer surface of the elliptical block 13. The elliptical block 13 rotates at a certain angle, tilting, and the tilted elliptical block 13 presses against and locks the outer surface of the pen. Then slide the rubber sleeve 14 upwards, causing it to engage with the annular groove. The anti-slip ring 15 prevents the pen holder 10 from slipping from the hand. Because the pen tip is fitted with the magnetic suction device 3, the tip is relatively heavy. To improve writing comfort, the counterweight ring 11 can be removed to avoid top-heavy writing. When writing, with the pen tip facing upwards, the magnetic suction piece 18 flips under gravity into the suction cup 16, and the ball tip 17... When not in use, the magnetic suction device 3 and the pen can be placed horizontally or vertically on the table, with the magnetic suction plate 18 partially exposed, providing magnetic attraction to prevent the pen from rolling off. The suction cup 16 can also be attached to the table to prevent it from falling. If the pen and magnetic suction device 3 are accidentally dropped, the pen will automatically flip in mid-air during the fall because the mass of the pen tip is greater than that of the pen nib, so that the nib faces upward. At the moment of impact, the suction cup 16 can act as a buffer, minimizing damage to the pen. The pen can move freely while also preventing it from falling. If it does fall, it will automatically flip during the fall. In addition, the pen holder 10 can quickly replace pens of different sizes, making the device highly versatile.

[0036] Working principle:

[0037] The base plate 1 and top plate 2 fold together when they are close to each other. Personnel can then perform risk assessments and calculations on the upper surfaces of the base plate 1 and top plate 2. A pen is inserted inside the magnetic suction device 3, and the pen is placed inside the magnetic suction slot 4 along with the magnetic suction device 3. When the desktop area needs to be expanded, the base plate 1 and top plate 2 are pulled left and right, moving away from each other under the constraint of the sliding rod 24. Three movable plates 22 are located at the bottom of the top plate 2, each corresponding to a U-shaped tube 21. The equipment can be extended while folded and combined. The expansion has three positions, from left to right. When the slanted opening at the bottom left side of the top plate 2 passes the outer surface of the right side of the leftmost movable plate 22, the compression spring 28 pushes the piston 26 to slide to the right along the inner surface of the gas cylinder 29. The high-pressure air inside the gas cylinder 29 is injected into the U-shaped tube 21 through the air inlet pipe 20. The push rod 30 pushes the movable plate 22 upward until the upper surface of the movable plate 22 is horizontally aligned with the upper surface of the top plate 2. As the top plate 2 continues to move to the right, the outer surface of the left side of the top plate 2 passes the upper surface of the protrusion 25, and the slider 33... As the pressure on the right side decreases, the storage spring 32 pushes the slider 33 to the right via the horizontal rod 31, causing the lower surface of the slider 33 to slide along the upper surface of the protrusion 25. During this process, as the slider 33 moves to the right, the folding plate 34 is pulled to the right, and the downward-folded folding plate 34 gradually becomes horizontal. Since the bottom corner of the folding plate 34 initially abuts against the top of the support tube 35, the downward pressure forces the middle of the support tube 35 to seal, isolating the high-pressure gas inside the airbag 36. As the folding plate 34 stretches, the inside of the support tube 35 becomes connected. With the assistance of the spring 37, the gas inside the airbag 36 is injected into the support tube 35, the support tube 35 is straightened and abuts against the bottom of the folding plate 34. The folding plate 34 eliminates the gap on the left side when the slider 33 slides to the right. The folding plate 34 and the slider 33 eliminate the gap at the top of the protrusion 25. Together with the spring-loaded movable plate 22, they ensure that the gap between the bottom plate 1 and the top plate 2 is not too large when stretched, ensuring the flatness of the writing surface. This solves the problem of the traditional writing platform structure being fixed and having a large gap at the connection when the structure is changed.

[0038] Insert the tip of a pen that meets the maximum inner diameter of the pen holder 10 into the pen holder 10. Rotate the nut 12; under the action of the threaded connection, the beveled opening at the bottom of the nut 12 contacts and presses against the outer surface of the elliptical block 13. The elliptical block 13 rotates at a certain angle, tilting, and the tilted elliptical block 13 presses against and locks the outer surface of the pen. Then slide the rubber sleeve 14 upwards, causing it to engage with the annular groove. The anti-slip ring 15 prevents the pen holder 10 from slipping from the hand. Because the pen tip is fitted with the magnetic suction device 3, the tip is relatively heavy. To improve writing comfort, the counterweight ring 11 can be removed to avoid top-heavy writing. When writing, with the pen tip facing upwards, the magnetic suction piece 18 flips under gravity into the suction cup 16, and the ball tip 17... When not in use, the magnetic suction device 3 and the pen can be placed horizontally or vertically on the table, with the magnetic suction plate 18 partially exposed, providing magnetic attraction to prevent the pen from rolling off. The suction cup 16 can also be attached to the table to prevent it from falling. If the pen and magnetic suction device 3 are accidentally dropped, the pen will automatically flip in mid-air during the fall because the mass of the pen tip is greater than that of the pen nib, so that the nib faces upward. At the moment of impact, the suction cup 16 can act as a buffer, minimizing damage to the pen. The pen can move freely while also preventing it from falling. If it does fall, it will automatically flip during the fall. In addition, the pen holder 10 can quickly replace pens of different sizes, making the device highly versatile.
