Financial tax document safety box

Abstract

The invention discloses a financial and tax document safety box which is mainly composed of a safety box body, a cooling block, a torsion bar, a drawing box and the like. The safety box has the advantages that the temperature rise speed of the safety box is slowed down when a fire occurs, and when the fire occurs outside the safety box, the temperature of external flames can bake the safety box, so that the temperature of the safety box rises rapidly, and water in a circulating cavity and a cooling cavity is heated; the water slowly flows and exchanges heat in the circulating cavity and the cooling cavity after being heated, so that the water in the circulating cavity and the cooling cavity is heated together, when the water temperature reaches the temperature at which the wax ring can be dissolved, the wax ring is heated to be dissolved and decomposed, so that the ammonia block can penetrate through the wax ring to be fused with the water, and when the ammonia block is fused with the water, the ammonia block can penetrate through the cooling cavity to be fused with the water. The ammonia blocks can absorb heat in water, so that the temperature of the water is reduced, and the effect of delaying the water temperature rising speed is achieved.

Description

Technical Field

[0001] The present application relates to the technical field of safes, and in particular to a financial and tax document safe. Background Art

[0002] The fiscal and tax document safe is a confidential device specially designed for storing and protecting fiscal and tax related documents. This safe is not only used to physically protect the documents, but also to ensure the security of the documents through encryption technology. All information will be saved in the corresponding folder in a 256-bit encrypted way and set a label to prevent unauthorized access or leakage.

[0003] Based on this, document safes have certain shortcomings. For example, in the event of a fire, the external temperature heats the safe, making the temperature of the safe very high. Although the flame and temperature cannot break the safe, the temperature can be used to bake the internal temperature of the safe to reach the ignition point of the paper, causing the documents inside the safe to burn. In this way, the internal stored documents can be damaged without destroying the appearance of the safe.

[0004] When storing files, open cells or secondary encryption cells are usually used. In certain circumstances, such as when the safe user opens the safe, someone else writes down the password, or cracks the password, or when someone threatens to open the safe, the files inside will be visible, and it is impossible to hide important files. Summary of the invention

[0005] The present application proposes a financial and tax document safe, which has the advantages of increasing the storage life of documents in the event of a fire and multi-level concealment, so as to solve the above-mentioned background technical problems.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a financial and tax document safe, comprising a safe, a cabinet door movably installed on the front of the safe, a circulation chamber and a cooling chamber are opened inside the two sides and the rear side of the safe, water for cooling is arranged inside the circulation chamber and the cooling chamber, the circulation chamber is located at the outer circle of the cooling chamber, the circulation chamber and the cooling chamber are communicated with each other, and adjacent circulation chambers are communicated with each other, cooling blocks are evenly and fixedly installed inside the cooling chamber, a vertical slot is opened inside the safe, a first empty slot, a first draw slot, a second draw slot, and a second empty slot are opened in a linear array on one side of the vertical slot, the first empty slot is located above the inside of the safe, the second empty slot is located below the inside of the safe, a moving chamber is opened between the first draw slot, the second draw slot and the vertical slot, a sliding hole is opened inside the safe on one side of the top of the moving chamber, the sliding hole is communicated with the moving chamber, a torsion bar is rotatably installed at the bottom of the moving chamber, a draw box is slidably installed inside the first draw slot and the second draw slot, and a vertical draw box is slidably installed inside the vertical slot.

[0007] Through the above-mentioned structural arrangement, when a fire occurs outside the safe, the temperature of the water can be lowered, slowing down the rate at which the water temperature rises, thereby delaying time for the safe to preserve its internal files. While personnel are rescuing the fire, the files inside the safe will not be burned by the fire, thereby extending the storage time of the files inside the safe.

[0008] Furthermore, the cooling block includes a first sealing ring and a second sealing ring. The first sealing ring and the second sealing ring are respectively fixedly installed on the side of the cooling chamber close to the inside of the safe and the side of the circulation chamber close to the outside. A wax ring is fixedly installed between the first sealing ring and the second sealing ring. The wax ring is specifically precision cast low-temperature wax. The melting point of the wax ring is specifically in the range of 48°C-60°C. An ammonia block is fixedly installed on the inner ring of the wax ring between the first sealing ring and the second sealing ring. The ammonia block is specifically ammonium chloride (NH4Cl).

[0009] Through the above-mentioned structural setting, when the water temperature reaches a temperature that can dissolve the wax ring, the wax ring will be dissolved and decomposed by the heat, so that the ammonia block can pass through the wax ring and blend with the water. When the ammonia block blends with water, the ammonia block will absorb the heat in the water, causing the water temperature to drop and slowing down the rate at which the water temperature rises.

[0010] Furthermore, the outer ring of the torsion bar located inside the moving cavity is provided with a thread, and a slider is slidably installed above the torsion bar inside the moving cavity, a thread groove is opened at the bottom of the slider, the outer ring thread of the torsion bar is adapted to the thread groove at the bottom of the slider, and the slider is meshed with the torsion bar.

[0011] Furthermore, the slider is provided with two magnetic blocks of N pole and S pole on one side facing the sliding hole, and a magnetic column is slidably installed inside the sliding hole. The magnetic column is attracted to one of the two magnetic blocks of N pole and S pole by opposite polarity, and repels the other magnetic block by the same polarity.

[0012] Through the above-mentioned structural arrangement, when the torsion bar is twisted to rotate forward and drive the slider to move toward the inside of the safe, the slider and the magnetic column are attracted by opposite poles, causing the magnetic column to slide toward the slider; when the torsion bar is twisted to rotate backward and drive the slider to move toward the outside of the safe, the slider and the magnetic column are repelled by the same poles, causing the magnetic column to slide away from the slider.

[0013] Furthermore, the drawer box includes a first hidden box and a second hidden box, the first hidden box is movably installed on the top of the drawer box, the sliding hole is opened between the movable cavity and the interior of the first hidden box, a first magnetic surface is provided on one side of the drawer box close to one side of the first hidden box, a second magnetic surface is provided on one side of the first hidden box close to the drawer box at a position corresponding to the position of the first magnetic surface, and the second magnetic surface and the first magnetic surface are attracted to each other by opposite charges.

[0014] With the above-mentioned structural arrangement, half of the magnetic column slides into the first hidden box according to the magnetic repulsion, and the other half is stuck in the inside of the safe, so as to limit the position of the first hidden box. When the position of the first hidden box is limited by the magnetic column, the first hidden box cannot be taken out when the box is pulled out even if there is magnetic attraction between the first magnetic surface and the rotating strip. For example, if more important documents are placed in the first hidden box, secondary concealment can be achieved.

[0015] Furthermore, a second hidden box is slidably installed at the bottom of the drawer box, a rotating strip is rotatably installed on one side of the bottom of the drawer box, sliding grooves are provided on both sides of the bottom of the drawer box, the second hidden box is slidably installed between the sliding grooves, a retaining groove is provided on the ground at the end of the second hidden box close to the rotating strip, and column heads are provided on both sides of the end of the second hidden box away from the rotating strip, and the column heads are adapted to the sliding grooves.

[0016] Through the above-mentioned structural arrangement, when the drawer box is pulled out, the rotating bar is turned 90 degrees to release the position restriction of the second hidden box by the rotating bar. At this time, the second hidden box begins to droop around the column head due to gravity, so that the documents inside the second hidden box can be viewed or taken out. Placing more important documents inside the second hidden box can achieve secondary hiding, thereby achieving more secure placement of important documents.

[0017] The present application provides a financial and tax document safe, which can slow down the temperature rise rate of the safe when a fire occurs by setting up structures such as a circulation chamber, a cooling chamber, and a cooling block. When a fire occurs outside the safe, the temperature of the external flame will bake the safe, causing the temperature of the safe to rise rapidly, heating the water inside the circulation chamber and the cooling chamber. After the water is heated, it will slowly flow and exchange heat inside the circulation chamber and the cooling chamber, causing the water inside the circulation chamber and the cooling chamber to heat up together. When the water temperature reaches a temperature that can dissolve the wax ring, the wax ring will dissolve and decompose when heated, allowing the ammonia block to pass through the wax ring and blend with water. When the ammonia block blends with water, the ammonia block will absorb heat in the water to reduce the temperature of the water, thereby achieving the effect of slowing down the rate at which the water temperature rises.

[0018] The present application provides a financial and tax document safe, which realizes secondary hiding of more important documents by setting structures such as a drawer box, a first hidden box, and a second hidden box. When the torsion bar is twisted to rotate in the opposite direction to drive the slider to move toward the outside of the safe, the slider and the magnetic column repel each other with the same polarity, causing the magnetic column to slide in the direction away from the slider. According to the magnetic repulsion, half of the magnetic column slides to the inside of the first hidden box, and the other half is stuck in the inside of the safe to limit the position of the first hidden box. When the drawer box is pulled conventionally without turning the rotating strip, the second hidden box will not fall or move due to the position limit of the rotating strip. Placing more important documents in the second hidden box can achieve secondary hiding, thereby protecting important documents. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] See also Figure 1-Figure 8, comprising a safe 1, a cabinet door 11 is movably installed on the front of the safe 1, a circulation chamber 12 and a cooling chamber 13 are opened inside the two sides and the rear side of the safe 1, water for cooling is arranged inside the circulation chamber 12 and the cooling chamber 13, the circulation chamber 12 is located at the outer circle of the cooling chamber 13, the circulation chamber 12 and the cooling chamber 13 are communicated with each other, adjacent circulation chambers 12 are communicated with each other, cooling blocks 2 are evenly fixedly installed inside the cooling chamber 13, a vertical groove 141 is opened inside the safe 1, and a first empty groove 142 and a first drawer are opened in a linear array on one side of the vertical groove 141 inside the safe 1 Slot 143, second draw slot 144, second empty slot 145, the first empty slot 142 is located at the upper part of the safe 1, the second empty slot 145 is located at the lower part of the safe 1, a movable cavity 15 is opened between the first draw slot 143, the second draw slot 144 and the vertical slot 141, a sliding hole 16 is opened on one side of the top of the movable cavity 15 inside the safe 1, the sliding hole 16 is communicated with the movable cavity 15, a torsion bar 3 is rotatably installed at the bottom of the movable cavity 15, a draw box 4 is slidably installed inside the first draw slot 143 and the second draw slot 144, and a vertical draw box 5 is slidably installed inside the vertical slot 141.

[0024] See also Figure 1-Figure 5 The cooling block 2 includes a first sealing ring 21 and a second sealing ring 22. The first sealing ring 21 and the second sealing ring 22 are respectively fixedly mounted on the cooling chamber 13 near the inside of the safe 1 and the circulation chamber 12 near the outside. A wax ring 23 is fixedly mounted between the first sealing ring 21 and the second sealing ring 22. The wax ring 23 is specifically precision cast low-temperature wax. The melting point of the wax ring 23 is specifically in the range of 48°C-60°C. An ammonia block 24 is fixedly mounted on the inner ring of the wax ring 23 between the first sealing ring 21 and the second sealing ring 22. The ammonia block 24 is specifically ammonium chloride (NH4Cl). The reason why ammonium chloride absorbs heat when dissolved in water is that its ionization process requires energy absorption. Ammonium chloride is an ammonium salt. When it is dissolved in water, it will undergo ionization to generate ammonium ions and chloride ions. This process requires energy to destroy the ionic bonds in the ammonium chloride molecules, so it absorbs heat, causing the solution temperature to drop.

[0025] When a fire occurs outside the safe, the temperature of the external flame will bake the safe, causing the temperature of the safe to rise rapidly, heating the water inside the circulation chamber 12 and the cooling chamber 13. After the water is heated, it will slowly flow and exchange heat inside the circulation chamber 12 and the cooling chamber 13, causing the water inside the circulation chamber 12 and the cooling chamber 13 to heat up together. When the water temperature reaches a temperature capable of dissolving the wax ring 23, the wax ring 23 will be dissolved and decomposed by the heat, allowing the ammonia block 24 to pass through the wax ring 23 and blend with the water. When the ammonia block 24 blends with the water, the ammonia block 24 will absorb the heat in the water, causing the temperature of the water to drop, slowing down the rate at which the water temperature rises, and delaying time for the safe to save its internal documents. While personnel are rescuing the fire, the documents inside the safe will not be burned by the fire, thereby extending the storage time of the documents inside the safe.

[0026] See also Figure 1-Figure 8 The outer ring of the torsion bar 3 located inside the moving cavity 15 is provided with a thread, and a slider 31 is slidably installed above the torsion bar 3 inside the moving cavity 15. A thread groove is provided at the bottom of the slider 31. The outer ring thread of the torsion bar 3 is adapted to the thread groove at the bottom of the slider 31. The slider 31 is meshed with the torsion bar 3. When the torsion bar 3 rotates, the position of the slider 31 inside the moving cavity 15 can be changed. The side of the slider 31 facing the sliding hole 16 is provided with two magnetic blocks of N pole and S pole. A magnetic column 32 is slidably installed inside the sliding hole 16. The column 32 and one of the two magnetic blocks, the N pole and the S pole, are attracted by opposite poles, and repelled by the other. According to the principle of magnetic attraction, when the torsion bar 3 is rotated in the forward direction to drive the slider 31 to move toward the inside of the safe 1, the slider 31 and the magnetic column 32 are attracted by opposite poles, causing the magnetic column 32 to slide toward the slider 31. When the torsion bar 3 is rotated in the reverse direction to drive the slider 31 to move toward the outside of the safe 1, the slider 31 and the magnetic column 32 are repelled by the same pole, causing the magnetic column 32 to slide away from the slider 31.

[0027] See also Figure 1-Figure 10 The drawer box 4 includes a first hidden box 42 and a second hidden box 43. The first hidden box 42 is movably installed on the top of the drawer box 4. The sliding hole 16 is opened between the movable cavity 15 and the inside of the first hidden box 42. The second hidden box 43 is slidably installed on the bottom of the drawer box 4. A first magnetic surface 411 is provided on one side of the drawer box 4 close to the first hidden box 42. A second magnetic surface 421 is provided on the one side of the drawer box 4 close to the drawer box 4 at a position corresponding to the position of the first magnetic surface 411. The second magnetic surface 421 and the first magnetic surface 411 are oppositely attracted to each other. A rotating strip 412 is rotatably installed on one side of the bottom of the drawer box 4. Slide grooves 413 are opened on both sides of the bottom of the drawer box 4. The second hidden box 43 is slidably installed between the slide grooves 413. A retaining groove 431 is opened on the ground at the end of the second hidden box 43 close to the rotating strip 412. Column heads 432 are provided on both sides of the end of the second hidden box 43 away from the rotating strip 412, and the column heads 432 are adapted to the slide grooves 413.

[0028] When the torsion bar 3 is twisted to rotate in the opposite direction to drive the slider 31 to move toward the outside of the safe 1, the slider 31 and the magnetic column 32 repel each other, causing the magnetic column 32 to slide away from the slider 31. The magnetic column 32 slides halfway into the first hidden box 42 according to the magnetic repulsion, and the other half is stuck in the inside of the safe 1 to limit the position of the first hidden box 42. When the position of the first hidden box 42 is limited by the magnetic column 32, when the drawer 4 is pulled out, even if the first magnetic surface 411 and the rotating strip 412 are magnetically attracted, the first hidden box 42 cannot be pulled out. The hiding box 42 is taken out. For example, more important documents are placed inside the first hiding box 42 to achieve secondary hiding. The torsion bar 3 is twisted to rotate in the positive direction to slide the slider 31. The magnetic column 32 and the slider 31 are attracted to each other in different shapes. When the magnetic column 32 slides to fit with the slider 31, the position restriction of the first hiding box 42 is released. At this time, the drawer box 4 is pulled out again. Due to the magnetic attraction between the first magnetic surface 411 and the second magnetic surface 421, the drawer box 4 slides and drives the first hiding box 42 to slide together, so that the documents inside the first hiding box 42 can be viewed or taken out.

[0029] When the drawer 4 is pulled out, the turning bar 412 is moved 90 degrees to release the position restriction of the turning bar 412 on the second hidden box 43. At this time, the second hidden box 43 begins to droop around the column head 432 due to gravity, so that the documents inside the second hidden box 43 can be viewed or taken out. If the drawer 4 is pulled out normally without moving the turning bar 412, the second hidden box 43 will not fall or move due to the position restriction of the turning bar 412. Placing more important documents inside the second hidden box 43 can achieve secondary hiding. Through the secondary hiding setting of the first hidden box 42 and the second hidden box 43, more secure placement of important documents can be achieved, so that when others open the safe to view and take internal documents, more important documents will not be easily found.

[0030] The working principle is as follows: if more important documents are placed inside the first hidden box 42, secondary hiding can be achieved. When the torsion bar 3 is twisted to rotate in the opposite direction to drive the slider 31 to move toward the outside of the safe 1, the slider 31 and the magnetic column 32 repel each other with the same polarity, causing the magnetic column 32 to slide away from the slider 31. The magnetic column 32 slides halfway into the first hidden box according to the magnetic repulsion, and the other half is stuck in the inside of the safe 1, so as to limit the position of the first hidden box 42. When the position of the first hidden box 42 is limited by the magnetic column 32, the drawer box 42 can be pulled out. When the first hidden box 42 is pulled out, even if the first magnetic surface 411 and the rotating strip 412 are magnetically attracted, the first hidden box 42 cannot be taken out. The torsion bar 3 is twisted to rotate in the positive direction to slide the slider 31. The magnetic column 32 and the slider 31 are attracted to each other in different shapes. When the magnetic column 32 slides to fit the slider 31, the position restriction of the first hidden box 42 is released. At this time, the drawer box 4 is pulled out again. Due to the magnetic attraction between the first magnetic surface 411 and the second magnetic surface 421, the drawer box 4 will drive the first hidden box 42 to slide together when sliding, so that the files in the first hidden box 42 can be viewed or taken out. The more important documents can be placed in the second hidden box 43 to achieve secondary hiding. When the drawer 4 is pulled out, the rotating bar 412 is turned 90 degrees to release the position restriction of the second hidden box 43 by the rotating bar 412. At this time, the second hidden box 43 begins to sag around the column head 432 due to gravity, so that the documents in the second hidden box 43 can be viewed or taken out. If the drawer 4 is pulled out conventionally without turning the rotating bar 412, the second hidden box 43 will not fall or move due to the position restriction of the rotating bar 412. The secondary hiding setting of the first hidden box 42 and the second hidden box 43 can realize a more secure placement of important documents, so that when others open the safe to view and take the documents inside, the more important documents will not be easily found. When a fire occurs outside the safe, the temperature of the external flame will bake the safe, causing the temperature of the safe to rise rapidly. The flame will heat the water inside the circulation chamber 12 and the cooling chamber 13. After the water is heated, it will slowly flow and exchange heat inside the circulation chamber 12 and the cooling chamber 13, causing the water inside the circulation chamber 12 and the cooling chamber 13 to heat up together. When the water temperature reaches a temperature that can dissolve the wax ring 23, the wax ring 23 will dissolve and decompose when heated, allowing the ammonia block 24 to pass through the wax ring 23 and blend with the water. When the ammonia block 24 blends with the water, the ammonia block 24 will absorb the heat in the water, causing the temperature of the water to drop, slowing down the rate at which the water temperature rises, and delaying time for the safe to save its internal files.
