Description

Technical Field

[0001] This invention relates to the field of mobile shelving technology, specifically to a mobile shelving unit for storing evidence with anti-theft functionality. Background Technology

[0002] Mobile shelving, generally referring to mobile shelving units, offers a large storage capacity and effectively saves space. The shelving units are movable, and each row is equipped with a handbrake (self-locking handle). Multiple rows or a single row can move on guide rails. In use, mobile shelving is typically used for storing and retrieving archives and documents, offering advantages such as space saving, large storage capacity, aesthetic appeal, stability, security, and high confidentiality. However, existing mobile shelving systems lack effective anti-theft features. For example, the security and anti-theft capabilities of mobile shelving units used for storing evidence directly impact the handling of cases.

[0003] The existing devices and equipment still have the following defects:

[0004] ① Firstly, the unlocking panels of existing mobile shelving units are mostly exposed on the surface. If someone intends to steal evidence or documents, they can easily damage the unlocking panel and forcibly open the mobile shelving unit. This type of mobile shelving unit has poor anti-theft function. If some evidence is stored in the mobile shelving unit, it is easy for the case to be mishandled due to the theft of the evidence. In addition, there are no corresponding alarm reminder measures during the theft of evidence. Therefore, the security of existing mobile shelving units for storing evidence is low.

[0005] Secondly, during the use of mobile shelving, operators need to open and close the storage boxes. However, the damage caused by light to some paper evidence and archives during storage is not negligible. In particular, ultraviolet radiation has a great destructive effect on the cellulose and lignin in the paper, which will reduce the strength of the paper. Furthermore, direct sunlight and artificial light will damage the paper, which will not only shorten the shelf life of the paper, but also affect the normal access to the evidence.

[0006] ③ Thirdly, some paper-based evidence materials are extremely prone to mold growth in humid environments. Once mold grows on the paper, it is very difficult to treat. The penetration of mold will make the paper brittle and discolored, and even the writing will become blurred. The durability will decrease within a few days. Since the storage temperature of the archives is below 24 degrees Celsius, which is lower than the human body temperature, the temperature difference between the human body and the storage will increase the internal humidity of the archives when the person opens and closes the cabinet, thus affecting the storage of the paper.

[0007] Therefore, in view of this, the present invention proposes a mobile shelving unit for storing physical evidence with anti-theft function to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects achieved by the technical solution of the present invention are:

[0020] (1) Through the combined action of the cover plate, bottom cover, bottom hole, pull ring, bottom hole and tension spring, only professionals can operate the cover plate to slide upward to unlock it, while non-professionals cannot open the cover plate. Therefore, the unlocked panel has a good concealment function and anti-theft effect, thereby reducing the possibility of theft of physical evidence and materials inside the mobile shelving.

[0021] (2) Through the cooperation of slide rail, push rod one, limit hole and alarm button, if some non-professionals forcibly open the cover, the alarm will be triggered directly through the alarm button, so that the device has a good early warning function, and can promptly notify the management personnel to take countermeasures, which can effectively prevent the theft of physical evidence.

[0022] (3) Through the joint cooperation of the fixed plate, swing rod 1, light shield and connecting rod, the synchronous movement between the light shield and the cabinet door is realized. Since the light shield is a transparent plate with nano titanium dioxide coating on the surface, it has a good ultraviolet shielding function. Therefore, in the process of storing and taking out the archives, the light shield can effectively isolate the ultraviolet rays in the light, thereby avoiding the ultraviolet radiation from causing great damage to the paper, thus extending the preservation period of the paper archives.

[0023] (4) At the same time, opening and closing the cabinet door can drive the fan blades to blow the desiccant for drying, which can effectively prevent the user from affecting the humidity inside the storage box when opening and closing the cabinet door, thereby strictly controlling the humidity inside the mobile shelving and avoiding adverse effects such as mold and discoloration on the archives caused by humidity changes.

[0046] The complete usage steps and working principle of the above embodiments are as follows:

[0047] Before use: The device should be in the locked position, such as... Figure 1 and Figure 2As shown, one cabinet door 21 is open, while the other cabinet doors 21 are closed. The cover 24 on the left side of cabinet door 21 is at its lowest point, covering the fingerprint panel 22. The bottom cover 26 is perpendicular to the cabinet door 21, and its upper surface abuts against the linear guide rail 23. Figure 6 As shown, push rod 215 is located to the right of alarm button 217, as... Figure 7 The image shown is an overall view of the storage box 14 before use. At this time, the surface of the light shield 37 is parallel to the cabinet door 21, and as shown... Figure 9 As shown, the initial state of the rotating shaft 42 connected to the elastic torsion rope 410 is a stationary state, so the gear meshing part does not perform transmission, and therefore the fan blade 46 is stationary.

[0048] Depend on Figure 4 As shown, since the bottom of the bottom cover 26 is flush with the bottom of the cover plate 24, and the left side of the bottom cover 26 is flush with the left side of the cover plate 24, and the bottom cover 26 is restricted by the linear guide rail 23, and since the bottom cover 26 and the cover plate 24 are connected by a hinge 28, and since the hinge 28 and the cover plate 24 are not fixedly connected, and the hinge 28 can slide relative to the cover plate 24 along the connecting shaft 29, and since the bottom surface of the bottom cover 26 is flush with the bottom surface of the cover plate 24, and the bottom cover 26 is subjected to the elastic force of the tension spring 212, at this time the right side of the bottom cover 26 coincides with the left side of the cover plate 24, so the bottom cover 26 is fixed without external force. Therefore, the cover plate 24 and the bottom cover 26 are jointly fixed to the outside of the fingerprint panel 22. Therefore, only a professional operator can pull the bottom cover 26 down from the bottom hole 27 with their finger. 6. The cover plate 24 can slide up and down along the linear guide rail 23 so that it can slide down the connecting shaft 29. Since the bottom cover 26 is located inside the bottom of the cover plate 24, it has a good concealment effect, making it difficult for non-professionals to open the cover plate 24 directly. Since the tension spring 212 is elastic, it can automatically reset when no external force is applied. Therefore, after the cover plate 24 is used up and down, the tension spring 212 will automatically pull the bottom cover 26 back to its initial state due to the elastic force. Thus, through the combined action of the cover plate 24, bottom cover 26, bottom hole 27, pull ring 211, bottom hole 27 and tension spring 212, only professionals can operate the cover plate 24 to slide up and use the fingerprint panel 22 to unlock it. Therefore, it has a good concealment and anti-theft effect.

[0049] Depend on Figure 6As shown, the end of push rod 215 furthest from cabinet door 21 moves with cover plate 24. When cover plate 24 slides up and down and cabinet door 21 rotates, push rod 215 rotates with cabinet door 21 and will not touch alarm button 217, thus not triggering an alarm. When a non-professional forcibly pulls cover plate 24 outward, push rod 215 will move outward with cover plate 24 and touch alarm button 217, triggering an alarm. The panel protection mechanism 2 is used in two ways: First, when cover plate 24 is opened correctly and cabinet door 21 is opened by entering a password or fingerprint, push rod 215 will rotate with cabinet door 21 and will not touch alarm button 217. Second, when a thief forcibly opens cover plate 24 outward incorrectly, push rod 215 will move outward with cover plate 24 and touch alarm button, triggering an alarm. ， Through the cooperation of slide rail 214, push rod 215, limit hole 216 and alarm button 217, the alarm 217 will be triggered when a non-professional forces open the cover 24. The device has a good alarm function, which can promptly notify the management personnel to protect the evidence and effectively prevent theft.

[0050] Depend on Figure 8 As shown, since the fixing plate 31 is fixed to the inner wall of the storage box 14, and the mounting block 312 is located on the right side of the cabinet door 21, and the swing rod 32 is connected to the mounting block 312 by a connecting rod, when the cabinet door 21 is opened, that is, when the operator rotates the cabinet door 21, the mounting block 312 will drive the connecting rod 311 to rotate, and the connecting rod 311 will drive the right-angle rod 38 to rotate, and the right-angle rod 38 will drive the connecting rod 35 and the connecting rod 34 to rotate. The connecting rod 34 will drive the swing rod 32 to rotate. At this time, the connecting rod 35 and the swing rod 312 will rotate. The first 32 together drive the connecting plate 36 to move, thereby driving the light-shielding plate 37 fixedly installed on the inner wall of the connecting plate 36 to move, thus realizing the synchronous movement between the light-shielding plate 37 and the cabinet door 21. The light-shielding plate 37 is a transparent plate with a nano titanium dioxide coating on its surface, which has a good ultraviolet shielding function. Since ultraviolet radiation in the light has a great damaging effect on paper during the storage of archives, it will reduce the strength of the paper. Therefore, the light-shielding plate 37 can effectively remove the damage caused by direct ultraviolet radiation to the archives, thereby extending the preservation period of the paper archives.

[0051] Depend on Figure 9 and Figure 11As shown, since the elastic torsion rope 410 is movably connected to the inner wall of the connecting hole 412, and the connecting hole 412 is fixed on the right side of the cabinet door 21, when the cabinet door 21 is opened, the rotation of the cabinet door 21 will drive the elastic torsion rope 410 to move. Since the elastic torsion rope 410 passes through the through hole 411, and the through hole 411 is opened on the fixed base plate 41 fixed on the surface of the storage box 14, and since the elastic torsion rope 410 is movably connected to the outer wall of the rotating shaft 42, and the outer wall of the rotating shaft 42 is fixedly connected to the large gear 43 with a shaft, the moving elastic torsion rope 410 will drive the rotating shaft 42 to rotate, thereby driving the synchronous belt 44 to mesh with the large gear 43 with a shaft, and then driving the small gear 47 with a shaft to mesh, thereby driving the fan blade 46 fixed on the outer wall of the small gear 47 to rotate. Since the desiccant is placed inside the cavity 45 of the drying box 48, and the drying box 48 can be removed for desiccant replacement, and since ventilation openings 413 are installed on both the front and rear sides of the storage box 14, the fan blades 46 will blow the desiccant to dry the inside of the storage box 14. Because the human body temperature is high, the ambient air temperature is high when the evidence is taken out, which creates a temperature difference with the temperature inside the cabinet, which can easily cause water vapor to form inside the cabinet and increase the humidity inside the cabinet, causing the stored evidence to become damp and damaged. Therefore, opening and closing the cabinet door 21 can drive the fan blades 46 to blow the desiccant for drying, which can effectively prevent the user from affecting the humidity inside the storage box 14 when opening and closing the cabinet door 21, thereby strictly controlling the humidity inside the mobile shelving and avoiding adverse effects such as mold and discoloration of the archives caused by humidity changes.

[0052] Since the two ends of the spherical connecting rod 415 are rotatably connected to the inner wall of the fixed block 414 and the spherical guide rail 416, and the spherical guide rail 416 is located on the right side of the cabinet door 21, rotating the cabinet door 21 will drive the spherical connecting rod 415 to move up and down. When the cabinet door 21 rotates to a certain angle, the end of the spherical connecting rod 415 near the spherical guide rail 416 will move to the bottom of the spherical guide rail 416, thereby fixing the angle of the cabinet door 21. This prevents the cabinet door 21 from automatically closing due to the elastic reset of the elastic torsion rope 410 during the opening process. Furthermore, since the bottom of the spherical guide rail 416 has a feature that allows the push rod 41 to move... 7. The small hole moves up and down, and the inner wall of the push rod 417 is rotatably connected to the outer wall of the fixed shaft 418. The fixed shaft 418 is fixed on the cabinet door 21. Therefore, when the spherical connecting rod 415 fixes the opening angle of the cabinet door 21, only the push rod 417 needs to be pushed to push the spherical connecting rod 415 upward, thereby realizing the automatic reset of the cabinet door 21. Through the cooperation between the fixed block 414, the spherical connecting rod 415, the spherical guide rail 416, the push rod 417 and the fixed shaft 418, the cabinet door 21 will not automatically close due to the elasticity of the elastic torsion rope 410, which can prevent the operator from being injured by the automatic closing of the cabinet door 21.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
