Description

Technical Field

[0001] This invention relates to the field of filing cabinet technology, and in particular to a filing cabinet with anti-theft function and its usage method. Background Technology

[0002] When using filing cabinets to store important documents, relying on a single locking method for theft prevention is easily cracked, has low security, and is unlikely to be effective in preventing theft. Therefore, a different filing cabinet design is needed.

[0003] Patent application number CN213882340U discloses an anti-theft filing cabinet for office use. By closing the first cabinet door and pressing the pressure switch, the first electric push rod extends the fixing pin into the hole on the right side of the first placement slot, thereby closing the first cabinet door with the extension baffle and the cabinet body. At the same time, the sealing plate extends from the mounting slot into the insertion slot by the second electric push rod, thereby dividing the first placement slot. The filing cabinet is locked by the fixing pin being inserted into the hole. This locking method is relatively simple and has low security.

[0004] We designed a filing cabinet with dual locking mechanisms and anti-theft features, along with its usage method, to overcome the limitations of existing filing cabinets with relatively simple locking mechanisms and low security. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a filing cabinet with anti-theft function and a method of use with dual locking mechanism, so as to overcome the disadvantage of the relatively simple locking mechanism of the existing filing cabinet.

[0006] To achieve the above objectives, the present invention provides the following solution: a filing cabinet with anti-theft function, comprising a filing cabinet, an anti-theft door, and a password electronic screen. The anti-theft door is hinged to the front of the filing cabinet, and the password electronic screen is installed on the right side of the front wall of the anti-theft door. The filing cabinet also includes an anti-theft mechanism and a locking mechanism. The anti-theft mechanism for locking the anti-theft door is provided on the right side of the anti-theft door, and the locking mechanism for locking the anti-theft door is provided between the anti-theft door and the filing cabinet.

[0007] As an improvement to the above solution, the anti-theft mechanism includes a handle, gear, pointer, first anti-theft lock, first limit block, fixing block, second anti-theft lock, and first compression spring. The handle is rotatably connected to the right side of the anti-theft door. The pointer is connected to the front top of the handle, and the gear is connected to the rear of the handle. The first limit block is connected to the right side of the rear wall of the anti-theft door. The first anti-theft lock is slidably connected to the first limit block. The first anti-theft lock is slidably connected to the gear. A first slot is opened on the front right side of the inner right wall of the filing cabinet. After the first anti-theft lock moves, it engages with the first slot on the upper side. A fixing block is connected to the right side of the rear wall of the anti-theft door. The second anti-theft lock is slidably connected to the fixing block. The second anti-theft lock meshes with the gear. After the second anti-theft lock moves, it engages with the first slot on the lower side. A first compression spring is connected between the second anti-theft lock and the fixing block. The first compression spring is wound around the second anti-theft lock. When the handle is rotated, it drives the pointer and gear to rotate. The first anti-theft lock moves to the right, and the second anti-theft lock moves to the left, away from the first slot on the lower side.

[0008] As an improvement to the above solution, the locking mechanism includes a locking rod, a second limiting block, and a second compression spring. The second limiting block is connected to the right side of the rear wall of the security door. The locking rod is slidably connected to the second limiting block. The second compression spring is connected between the locking rod and the second limiting block. The second compression spring is wrapped around the locking rod. A second slot is opened on the front side of the bottom of the filing cabinet. After the locking rod moves, it engages with the second slot.

[0009] As an improvement to the above solution, an unlocking stabilizing mechanism for locking the handle is also included. The unlocking stabilizing mechanism includes a style button, a locking pin, and a third compression spring. Style buttons are evenly connected to the left side of the front wall of the handle. A locking pin is slidably connected to the lower left side of the handle. A third compression spring is connected between the locking pin and the handle. The third compression spring is wrapped around the front side of the locking pin. A third slot is evenly opened on the right side of the front wall of the security door. After the locking pin moves, it engages with the third slot.

[0010] As an improvement to the above solution, it also includes an unlocking security mechanism for locking the support rod. The unlocking security mechanism includes a security unlocking pin and a fourth compression spring. The security unlocking pin is slidably connected to the right side of the security door. The security unlocking pin is connected to the security door and the fourth compression spring is wound around the security unlocking pin. A fourth slot is opened on the lower side of the support rod.

[0011] As an improvement to the above solution, it also includes a hidden lock mechanism for locking the security door. The hidden lock mechanism includes a hidden shaft, a through groove on the upper right side of the filing cabinet, a hidden shaft slidably connected to the through groove, and a fifth slot on the upper rear wall of the security door. After the hidden shaft moves, it engages with the fifth slot.

[0012] As an improvement to the above solution, a deception locking mechanism for limiting the anti-theft door is also included. The deception locking mechanism includes a stop, a rotating pin, a stop pin, and a fifth compression spring. The stop is connected to the upper right wall of the anti-theft door, the rotating pin is rotatably connected to the front right wall of the filing cabinet, the stop pin is slidably connected to the front of the rotating pin, and the fifth compression spring is connected between the stop pin and the rotating pin. The fifth compression spring is located inside the stop pin, and a locking square hole is opened on the right side of the rear wall of the anti-theft door. After the rotating pin rotates, it engages with the locking square hole.

[0013] The steps for using a filing cabinet are as follows:

[0014] Step 1: Place the filing cabinet in a suitable location;

[0015] Step 2: Enter the correct password on the combination lock to unlock the security door;

[0016] Step 3: Manually turn the security door to open the filing cabinet, and place the important documents inside. After placing the documents, manually turn the security door in the opposite direction to close the filing cabinet.

[0017] The advantages of this invention are: 1. This invention unlocks the security door by having people press the correct password on the electronic password screen, and then people manually turn the handle to move the second anti-theft lock to the left away from the first slot on the lower side, thereby achieving a double locking effect and a high level of security;

[0018] 2. By rotating the handle, the locking pin is driven to rotate. When the handle is rotated to the appropriate position, people manually move the locking pin backward, thereby compressing the third compression spring. Then the locking pin engages with the third slot, thus achieving the locking effect and preventing the handle from rotating easily.

[0019] 3. By manually moving the hidden shaft forward, when the hidden shaft moves forward and engages with the fifth slot, people release the hidden shaft, thus achieving a locking effect, strengthening the protection of documents and preventing the security door from being easily opened.

Detailed Implementation

[0036] The present invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0037] Example 1

[0038] A filing cabinet with anti-theft function, now for reference. Figures 1-3 It includes a filing cabinet 1, a security door 2, a password electronic screen 3, a security mechanism 4, and a locking mechanism 5. The front of the filing cabinet 1 is hinged to the security door 2. The security mechanism 4 is located on the right side of the security door 2. The locking mechanism 5 is located between the security door 2 and the filing cabinet 1. The password electronic screen 3 is installed on the right side of the front wall of the security door 2.

[0039] For reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The anti-theft mechanism 4 includes a handle 41, a gear 42, a pointer 421, a first anti-theft lock 43, a first limiting block 44, a fixing block 46, a second anti-theft lock 47, and a first compression spring 48. The handle 41 is rotatably connected to the right side of the anti-theft door 2. The pointer 421 is welded to the front top of the handle 41, and the gear 42 is welded to the rear of the handle 41. The first limiting block 44 is welded to the right side of the rear wall of the anti-theft door 2. The first anti-theft lock 43 is slidably connected to the first limiting block 44, and the first anti-theft lock 43 slides with the gear 42. The filing cabinet 1 has two first slots 45 on the front right side of the inner right wall. After the first anti-theft lock 43 moves, it engages with the first slot 45 on the upper side. The right side of the rear wall of the anti-theft door 2 is welded with a fixing block 46. The fixing block 46 is slidably connected to the second anti-theft lock 47. The second anti-theft lock 47 meshes with the gear 42. After the second anti-theft lock 47 moves, it engages with the first slot 45 on the lower side. A first compression spring 48 is connected between the second anti-theft lock 47 and the fixing block 46. The first compression spring 48 is wrapped around the second anti-theft lock 47.

[0040] For reference Figure 3 and Figure 7 The locking mechanism 5 includes a locking rod 51, a second limiting block 52, and a second compression spring 53. The second limiting block 52 is welded to the right side of the rear wall of the anti-theft door 2. The locking rod 51 is slidably connected to the second limiting block 52. After the second anti-theft lock 47 moves, it contacts the locking rod 51. The second compression spring 53 is connected between the locking rod 51 and the second limiting block 52. The second compression spring 53 is wrapped around the locking rod 51. A second slot 54 is opened on the front side of the bottom of the filing cabinet 1. After the locking rod 51 moves, it engages with the second slot 54.

[0041] When people need to use filing cabinet 1, they can use this anti-theft filing cabinet. First, they place the anti-theft filing cabinet in a suitable position. Then, they manually enter the correct password on the electronic password screen 3. After entering the password, the anti-theft door 2 unlocks. Then, they manually turn the handle 41, causing the pointer 421 to rotate, which in turn rotates the gear 42. This causes the first anti-theft lock 43 to move upward and then to the right, while the second anti-theft lock 47 moves to the left, away from the lower first slot 45. The first compression spring 48 is compressed. When the second anti-theft lock 47 moves to the left and contacts the holding rod 51, the second anti-theft lock 47 drives the holding rod 51 to move downward, and the second compression spring 53 is compressed. When the pointer 421 rotates beyond a suitable angle, the first anti-theft lock 43 moves into the upper first slot 45, and at the same time, the holding rod 51 moves downward into the second slot 54. This achieves a stronger anti-theft effect, preventing criminals from easily breaking into the anti-theft door. 2. When the pointer 421 rotates to the appropriate angle, the first anti-theft lock 43 and the second anti-theft lock 47 are both away from the first slot 45, and the retaining rod 51 is not engaged with the second slot 54. People can manually turn the anti-theft door 2 clockwise to open the filing cabinet 1. Then, people put the documents into the filing cabinet 1. After placing them, people manually turn the anti-theft door 2 counterclockwise. When the anti-theft door 2 closes the filing cabinet 1, people manually turn the handle 41 in the opposite direction, so that the pointer 421 and the gear 42 rotate in the opposite direction, thereby causing the first anti-theft lock 43 to move to the left and then downward, causing the second anti-theft lock 47 to move to the right. Then, the second compression spring 53 resets and drives the retaining rod 51 to move upward. When the pointer 421 rotates to the appropriate position in the opposite direction, the second anti-theft lock 47 engages with the first slot 45 on the lower side, thus achieving a reinforcement effect, which is beneficial for the preservation of documents. When people need to take out the documents, they can manually turn the anti-theft door 2 clockwise according to the above steps and take out the documents.

[0042] Example 2

[0043] Based on Example 1, now refer to Figure 1 , Figure 8 and Figure 9 It also includes an unlocking stabilizing mechanism 6, which includes style buttons 61, latches 62 and third compression springs 64. Five style buttons 61 are evenly welded on the left side of the front wall of the handle 41. A latch 62 is slidably connected to the lower left side of the handle 41. A third compression spring 64 is connected between the latch 62 and the handle 41. The third compression spring 64 is wrapped around the front side of the latch 62. Six third slots 63 are evenly opened on the right side of the front wall of the security door 2. After the latch 62 moves, it engages with the third slots 63.

[0044] For reference Figure 1 , Figure 3 , Figure 10 and Figure 11It also includes an unlocking security mechanism 7, which includes a security unlocking pin 71 and a fourth compression spring 72. A fourth slot 73 is opened on the lower side of the support rod 51. The security unlocking pin 71 is slidably connected to the right side of the security door 2. The fourth compression spring 72 is connected between the security unlocking pin 71 and the security door 2. The fourth compression spring 72 is wrapped around the security unlocking pin 71.

[0045] For reference Figure 2 , Figure 12 and Figure 15 It also includes a hidden lock mechanism 8, which includes a hidden shaft 81. A through groove 82 is opened on the upper right side of the filing cabinet 1, and a fifth slot 83 is opened on the upper rear wall of the anti-theft door 2. The hidden shaft 81 is slidably connected to the through groove 82. After the hidden shaft 81 moves, it engages with the fifth slot 83.

[0046] For reference Figure 2 , Figure 13 , Figure 14 and Figure 15 It also includes a deception locking mechanism 9, which includes a stop 91, a rotating pin 92, a stop pin 93, and a fifth compression spring 94. The stop 91 is welded to the upper right wall of the security door 2. The rotating pin 92 is rotatably connected to the front right wall of the filing cabinet 1. The stop pin 93 is slidably connected to the front of the rotating pin 92. The stop pin 93 is in contact with the stop 91. Two fifth compression springs 94 are connected between the stop pin 93 and the rotating pin 92. The fifth compression springs 94 are located inside the stop pin 93. A locking square hole 95 is opened on the right side of the rear wall of the security door 2. After the rotating pin 92 rotates, it engages with the locking square hole 95.

[0047] When handle 41 is rotated, it causes the locking pin 62 to rotate. When the pointer 421 rotates to the appropriate position, people can manually move the locking pin 62 backward, thereby compressing the third compression spring 64. When the locking pin 62 moves backward into the third slot 63, people can stop moving the locking pin 62 backward, thus achieving the effect of limiting the movement and preventing the handle 41 from rotating excessively after the filing cabinet 1 is opened. When people need to rotate handle 41 in the opposite direction, they can release the locking pin 62, thereby causing the third compression spring 64 to reset and drive the locking pin 62 to move forward and reset away from the third slot 63. Then people can manually rotate handle 41 in the opposite direction.

[0048] In the initial state, the fourth compression spring 72 is compressed, and the holding rod 51 moves downward, causing the fourth slot 73 to move downward. When the security unlocking pin 71 contacts the fourth slot 73, the fourth compression spring 72 resets, causing the security unlocking pin 71 to move backward and engage with the fourth slot 73, thus achieving the locking effect. Before people turn the handle 41 in the opposite direction, they can manually move the security unlocking pin 71 forward, causing the fourth compression spring 72 to be compressed. When the security unlocking pin 71 moves forward away from the fourth slot 73, people can manually turn the handle 41 in the opposite direction. Then, the holding rod 51 moves upward, causing the fourth slot 73 to move upward, and then people can release the security unlocking pin 71.

[0049] When people need to turn the security door 2 clockwise, they can manually move the hidden shaft 81 backward. When the hidden shaft 81 moves backward away from the fifth slot 83, people can turn the security door 2 clockwise. After the security door 2 closes the filing cabinet 1, people can manually move the hidden shaft 81 forward. When the hidden shaft 81 moves forward and engages with the fifth slot 83, people can release the hidden shaft 81, thus achieving the locking effect.

[0050] When people need to turn the security door 2 clockwise, they can manually move the stop pin 93 backward, which will compress the fifth compression spring 94. After the stop pin 93 moves backward away from the stop frame 91, people can manually turn the security door 2 clockwise, which will cause the stop frame 91 to rotate clockwise. The counterclockwise rotation of the security door 2 will cause the stop frame 91 to rotate counterclockwise. After the security door 2 closes the filing cabinet 1, people can release the stop pin 93, which will cause the fifth compression spring 94 to reset and drive the stop pin 93 to move forward and reset, locking the stop frame 91. When criminals manually turn the rotating pin 92, the rotating pin 92 will engage with the locking square hole 95, thus achieving an indirect anti-theft effect. After being discovered, people can manually turn the rotating pin 92 counterclockwise back to the initial position.

[0051] The steps for using a filing cabinet are as follows:

[0052] Step 1: Place the filing cabinet in a suitable location;

[0053] Step 2: Enter the correct password on the combination lock to unlock the security door;

[0054] Step 3: Manually turn the security door to open the filing cabinet, and place the important documents inside. After placing the documents, manually turn the security door in the opposite direction to close the filing cabinet.

[0055] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
