Description

Technical Field

[0001] The utility model relates to the technical field of filing cabinets, in particular to a confidential filing cabinet. Background Art

[0002] In the office, there are often many important internal documents of the company, and these documents need to be protected by confidential filing cabinets to ensure the security of the company's internal information; traditional confidential filing cabinets generally use mechanical password locks, which are troublesome to unlock and easy to crack, and can no longer meet the more stringent confidentiality needs. At the same time, the existing digital lock filing cabinets such as fingerprint password filing cabinets are often too simple in structure. All documents will be exposed if only one layer of security password is cracked. Therefore, a confidential filing cabinet that can easily and quickly unlock, increase the security level and increase the difficulty of cracking and the degree of confidentiality is needed to solve the problems that traditional confidential filing cabinets cannot solve.

[0003] For example, the patent with announcement number CN216741163U provides a filing cabinet with a confidentiality function, which includes a cabinet body, an opening and closing door, and a password lock. The opening and closing door is locked by a first locking device and a second locking device, and the cabinet body is used to store files by placing a plate, a partition and a storage box. The application has a simple structure and can achieve the purpose of protecting files from theft with simple operations. However, this solution still belongs to a single-layer confidentiality-level confidential filing cabinet. After the first-layer password is cracked, the filing cabinet can be opened. After the first-level password is cracked, the second-level insurance cannot be automatically generated without increasing the cost and complexity of the structure. This also makes it impossible for this solution to further increase security; this solution also cannot achieve free adjustment of the internal space, and cannot freely adjust the height and width of each compartment according to actual needs; this solution has a low level of confidentiality and cannot hide the most important archival documents, so that archival documents of different importance levels are placed in a large space, which can easily cause confusion and loss; this solution also cannot achieve adsorption of the confidential filing cabinet to the ground, so that the filing cabinet can be moved and kicked over at will, which can easily cause the loss of the safe.

The posture control of the confidentiality working process of the filing cabinet is determined by the suction and adhesion fixing device 1, the double-door sequential interlocking device 2 and the variable-distance double-space storage device 3. The posture of the suction and adhesion fixing device 1 is determined by the double-door sequential interlocking device 2, and the posture of the variable-distance double-space storage device 3 is determined by the double-door sequential interlocking device 2. Therefore, the double-door sequential interlocking device 2 is the core of the confidentiality working process of the filing cabinet.

[0032] Taking the first embodiment as an example, during the locking process, the fingerprint password lock of the left safety door 201 on the double-door sequential interlocking device 2 drives the locking electric push rod 203 to drive the first locking slider 202 to slide horizontally, and the first locking slider 202 drives the second locking slider 207 to slide horizontally as a whole, thereby realizing the function of the first locking slider 202 pushing the second locking slider 207 open. At this time, the safety spring 206 will be compressed; when the second locking slider 207 slides horizontally, the second locking slider 207 drives the locking short pin 209 to slide downward through the first locking link 208, and is inserted into the first locking slider 202 in the vertical direction.

The second locking slider 207 is manually pushed inward, and the second locking slider 207 drives the locking short pin 209 and the pin latch assembly 210 to slide through the first locking link 208 and the second locking link 211, so that the locking short pin 209 and the pin latch assembly 210 are locked. Component 210 is pulled out from the outer safe body 204 to realize the complete unlocking function; when the internal space needs to be adjusted, the position and number of the first magnetic sliding partition 302 and the second magnetic sliding partition 303 on the variable-distance dual-space storage device 3 are adjusted to adjust the compartment space. At the same time, the separation function of the separation adjustment component 304 and the up and down sliding of the variable-distance support plate 30401 are used to adjust the compartment space and separate the hidden space.

In the through hole, the second locking slide 207 also drives the locking long pin 21001 of the pin latch assembly 210 to be inserted into the through hole of the first locking slide 202 along the vertical direction through the second locking link 211, and at the same time, the pin latch electric push rod 21003 on the locking long pin 21001 will be further extended to increase the length of the first locking slide 202, thereby realizing the simultaneous locking function of the left safety door 201 and the right safety door 205; during the opening process, after the fingerprint unlocks the fingerprint password lock of the left safety door 201, the locking electric push rod 203 drives the first locking slide 202 The second locking slider 207 is retracted, and the safety spring 206 drives the second locking slide 207 to rebound. The second locking slide 207 drives the locking short pin 209 and the pin plug lock assembly 210 to slide through the first locking link 208 and the second locking link 211, so that the pin head of the locking short pin 209 and the pin plug lock head 21002 of the pin plug lock assembly 210 are inserted into the locking hole of the outer safe body 204, thereby unlocking the left safety door 201. At the same time, after the second locking slide 207 rebounds, the electromagnet in the second locking slide 207 is energized and magnetically fixed to the right safety door 205, thereby locking The separate locking function of the right safety door 205 is realized, so that the second safety level is automatically generated after the first safety level is unlocked; then the fingerprint unlocks the fingerprint password lock of the right safety door 205, so that the electromagnet in the second locking slider 207 is powered off, and then the second locking slider 207 is manually pushed inward, and the second locking slider 207 drives the locking short pin 209 and the pin latch assembly 210 to slide through the first locking link 208 and the second locking link 211, so that the locking short pin 209 and the pin latch assembly 210 are pulled out from the outer safe body 204 to realize the complete unlocking function.

[0035] like Figure 6 , Figure 7 and Figure 8As shown, the most important documents are placed on the fixed support plate 30407 of the separation and adjustment assembly 304, and then the space partition plate 30406 and the fixed support plate 30407 on the separation and adjustment assembly 304 are slidably installed on the inner safe body 301, so that the space partition plate 30406, the fixed support plate 30407 and the inner safe body 301 form a closed hidden space to achieve the concealment function of the most important documents; manually lift the variable pitch brake pad 30403, and then manually rotate the variable pitch wheel 30405, the variable pitch wheel 30405 drives the variable pitch lead screw 30402 to rotate, and the variable pitch lead screw 30402 drives The variable pitch support plate 30401 moves up and down, and the variable pitch brake pad 30403 is manually released. The variable pitch spring 30404 drives the variable pitch brake pad 30403 to clamp the variable pitch wheel 30405. Then, according to the upper and lower spaces of the compartment, a certain number of first magnetic sliding partitions 302 and second magnetic sliding partitions 303 are magnetically attracted to the inner safe body 301 and the variable pitch support plate 30401. At the same time, the first magnetic sliding partition 302 and the second magnetic sliding partition 303 in the middle position are used to divide the internal space into two independent spaces on the left and right to cooperate with the two confidentiality levels, thereby realizing the free adjustment function of the internal compartment space.
