Description

Technical Field

[0001] This utility model relates to the technical field of door bolt structure devices, and in particular to a dual-control safe door bolt mechanism. Background Technology

[0002] Definition of cabinet: A container used for storing clothes, documents, books, etc., usually square or rectangular, and generally made of wood or iron. A cabinet is a type of rectangular furniture or office supply, tall in shape, used for storing items.

[0003] The use of cabinets began in the Xia, Shang, and Zhou dynasties, when they were called "du". By the Ming and Qing dynasties, cabinets had become essential furniture in the home, and their forms had become standardized. Ming and Qing cabinets can be categorized by shape into square-corner cabinets, round-corner cabinets, and open-shelf cabinets; different shapes result in different components. Cabinet furniture mainly refers to various types of cabinets made of materials such as wood, engineered wood, or metal, serving different purposes.

[0004] To make the safe more secure, a double-lock mechanism is used to lock it.

[0005] A typical double-lock safe uses a key to extend the bolt and lock the safe.

[0006] However, the existing key mounting points are easily disassembled or the lock parts are easily opened by thieves, so they are not very secure.

[0007] To address this, a dual-control safe bolt mechanism was designed, which allows the safe to be self-locked from the inside by an external controller, thus making the safe more secure. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a dual-control safe door bolt mechanism, which can control the door bolt to lock the safe from the inside through an external controller, thereby making the safe safe safer.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dual-control safe door bolt mechanism, comprising: A door panel, on which a lock plate and a mechanism frame are fixedly connected; The top and bottom of the mechanism frame are respectively limited by sliding connections of an upper door bolt and a lower door bolt; An electric telescopic device and a guide positioning block are fixedly installed on the locking plate. The telescopic end of the electric telescopic device is provided with a telescopic rod. The connecting rod is placed in the rectangular through hole of the guide positioning block. The center of the connecting rod is provided with a central hole that matches the linkage pin, and the upper and lower parts are symmetrically provided with slot-shaped holes that match the shaft screw. The shaft screw is fixedly connected to the end of the telescopic rod. The upper slide plate is provided with an upper drive groove that cooperates with the linkage pin. The upper slide plate is fixedly connected to an upper connecting angle iron, and the upper connecting angle iron is fixedly connected to an upper door bolt. The lower sliding plate is provided with a lower drive groove that cooperates with the linkage pin. The lower sliding plate is fixedly connected to a lower connecting angle iron, and the lower connecting angle iron is fixedly connected to a lower door bolt. When the electric telescopic device retracts, the upper door bolt and the lower door bolt move up and down respectively to lock the door. The electric telescopic device is electrically connected to an external controller.

[0010] Furthermore, the locking plate is fixedly connected with a first guide boss, a second guide boss, and two heavy locking pins; The first guide boss post is provided with a first guide boss; The second guide boss post is provided with a second guide boss; The two aforementioned locking pin seats are provided with pin holes adapted to the locking pins and limiting grooves adapted to the resilient cotter pins. The pin hole is connected to a locking pin by a compression spring. The elastic cotter pin passes through the limiting groove and is fixed on the locking pin; Two locking plates are fixedly connected to the telescopic rod. The locking plates are provided with locking holes that can accommodate elastic cotter pins. When the electric telescopic device is attacked and damaged, the locking plates can disengage from the elastic cotter pins. The upper slide plate is provided with a first vertical guide groove, a first upper bend stop, and a first lower bend stop that cooperate with the first guide boss; the two locking pins can respectively block the first upper bend stop and the first lower bend stop to prevent the upper slide plate from moving downward. The lower slide plate is provided with a second vertical guide groove, a second upper bend stop, and a second lower bend stop that cooperate with the first guide boss; The two locking pins can respectively block the upper stop of the second bend and the lower stop of the second bend, thereby preventing the slide from moving upward.

[0011] Furthermore, it also includes a safe lock, which is fixedly installed on a lock plate. The safe lock is provided with a lock tongue, and a third switch touch panel is fixedly connected to the end of the lock tongue. When the lock tongue extends, it can drive the third switch touch panel to move down and press the third micro switch.

[0012] Furthermore, an anti-drilling disc is placed inside the guide positioning block, and in the locked state, the anti-drilling disc is coaxial with the linkage pin.

[0013] Furthermore, the first switch bracket and the second switch bracket are fixedly mounted on the lock plate; The first switch bracket is equipped with a first micro switch and a second micro switch, and the second switch bracket is equipped with a third micro switch; The upper slide plate is equipped with a first switch touch panel. When the upper door bolt moves up to the closed position, it causes the first switch touch panel to press the first micro switch. When the upper door bolt moves down in the opening direction, it causes the first switch touch panel to disengage from the first micro switch.

[0014] Furthermore, a shaft positioning sleeve is fixedly connected to the door panel, and the lock plate is provided with a positioning sleeve hole that matches the shaft positioning sleeve; The right side of the mechanism frame is limited by a sliding door bolt; A handle is fixed to one end of the handle shaft, and the other end passes through the door panel and the shaft positioning sleeve. A lever is installed on one end of the handle shaft through a locking nut, and a drive pin is fixed on the lever. The lower sliding plate is fixedly connected to a blocking square block; The horizontal slide plate is provided with a first horizontal guide groove that mates with the first guide boss, a second horizontal guide groove that mates with the second guide boss, a vertical groove that matches the drive pin, a vertical and horizontal groove that matches the blocking square block, a first clearance groove, a second clearance groove, and a locking bend. The horizontal slide plate is equipped with a second switch touch panel, and the horizontal slide plate is fixedly connected to a side door bolt. The horizontal sliding plate is located above the lower sliding plate. In the locked state, the blocking square block is located in the vertical square groove, blocking the movement of the horizontal sliding plate and thus preventing the side door bolt from moving in the opening direction. When the upper and lower door bolts are in the open position, the blocking square block is located at the intersection of the vertical and horizontal square grooves, and the horizontal sliding plate can move. When the handle shaft is rotated, the driving pin of the lever acts on the vertical groove, driving the horizontal sliding plate to move left and right, thereby moving the side door bolt to the open or closed position. In the locked state, the lock tongue of the safe lock blocks the lock bend, and the horizontal sliding plate cannot move, also preventing the side door bolt from moving in the opening direction, thus achieving double locking of the side door bolt.

[0015] Furthermore, a second switch touch panel is installed on the horizontal sliding plate. When the side door bolt moves to the right to the closed position, it causes the second switch touch panel to press the second micro switch; when the side door bolt moves to the left in the opening direction, it causes the second switch touch panel to disengage from the second micro switch.

[0016] Furthermore, it also includes a mechanism pressure plate, which is provided with a vertical blocking square groove adapted to the blocking square block and a horizontal blocking groove adapted to the linkage pin. The mechanism pressure plate is located above the horizontal slide plate and is fixedly installed on the first guide boss and the second guide boss. The blocking square block is located in the vertical blocking square groove, and the linkage pin is located in the horizontal blocking groove.

[0017] Furthermore, a vibration alarm is installed on the lock plate.

[0018] Compared with the prior art, the beneficial effects of this utility model include: The safe door bolts can be automatically opened or closed via an internal electric telescopic mechanism, thus protecting the safety of the safe. It adopts a dual authentication mechanism for on-site operators and remote administrators, which represents a key technological breakthrough compared to traditional and ordinary smart safe door bolt mechanisms, providing solid and reliable technical support for remote monitoring of safes; Dual Authentication and Collaborative Opening: Traditional safes typically rely on a single physical key, password, or a simple combination of both, which presents significant security limitations. This safe's mechanism employs an innovative dual authentication opening system. In practice, the on-site operator performs actions on the display screen while simultaneously operating the safe's lock; concurrently, a remote administrator authorizes the operation remotely via a designated device and precisely controls the electric extension mechanism. The safe door only opens when both the on-site operator and the remote administrator have completed their collaborative actions. This design significantly enhances the safe's security, effectively preventing security risks caused by single-person operational errors, forced entry, or insider intrusion. Furthermore, the separation of physical operation and remote authorization further elevates the safe's overall security level.

[0019] Linked Electric Drive and Re-lock Trigger: In this bolt mechanism, the electric telescopic device is tightly connected to the linkage pin at the bolt drive core point via a connecting rod, thereby achieving precise control over the movement of the upper and lower bolts. When the electric telescopic device is violently damaged, its locking hole separates from the elastic cotter pin. At this time, the compression spring is released instantly, driving the re-lock pin to pop out, thus triggering the re-locking mechanism to firmly lock the upper and lower bolts. Compared with the traditional method of directly driving the bolt with a motor, this design significantly enhances the safe's resistance to damage, providing more reliable protection.

[0020] Multi-dimensional and multi-layered bolt locking and anti-vandalism structure: This bolt mechanism is designed with multiple independent and complementary locking methods, providing comprehensive protection for the side bolt, top bolt, and bottom bolt. For the side bolt, three methods are used to achieve locking: mechanical blocking, bolt locking, and pressure plate limiting. Specifically, the blocking square block of the bottom slide plate falls into the vertical square groove of the horizontal slide plate (this locking state requires the top and bottom bolts to be opened first to release), while the bolt of the safe lock directly blocks the bending of the horizontal slide plate, and the blocking square block is also located in the vertical blocking square groove of the mechanism pressure plate. For the top and bottom bolts, their safety and anti-vandalism capabilities are ensured by the blocking of the relocking pin, the protection of the linkage pin, and the limiting of the linkage pin. The bending blocking of the top / bottom slide plates is blocked by the relocking pin, and the anti-drilling disc is coaxial with the linkage pin in the locked state, effectively protecting its core drive point. The movement of the linkage pin is limited by the linkage pin guide groove of the lock plate and the horizontal blocking groove of the mechanism pressure plate, which can resist attacks from the top and bottom. This multi-dimensional, multi-layered protective structure forms a tight three-dimensional security network. Any attack from a single direction or method will be blocked by at least one or even multiple layers of the structure, or will trigger a relocking mechanism, thus significantly improving the safe's resistance to damage.

[0021] Reliable Execution Unit: Considering various potential malfunctions during actual use, this door latch mechanism incorporates a hot backup in the main drive unit (electric expansion joint). The two electric expansion joints are arranged horizontally symmetrically and share a single connecting rod and linkage pin. Under normal circumstances, only one electric expansion joint needs to be used. If the main electric expansion joint fails, the backup electric expansion joint can be immediately activated to continue remote operation. This design significantly improves system reliability, ensuring that the door latch can still be operated remotely in unexpected situations, avoiding the problem of the safe failing to open due to a single component failure, and providing users with greater peace of mind.

[0022] Real-time Electronic Monitoring and Feedback: This door bolt mechanism digitizes and remotely transmits key information such as bolt position, latch status, relock status, and whether the safe has been attacked. Multiple microswitches and corresponding touch panels accurately detect the open / closed positions of the top and side bolts, as well as the open / closed status of the safe's latch. Simultaneously, combined with door status limit switches and vibration alarms, it can also detect the opening and closing of the door panel and whether the safe has been attacked. All these status changes are fed back to the operation display screen and designated devices in real time, providing clear operational guidance and security status confirmation for on-site operators and remote administrators, truly achieving remote monitoring. Whether it's opening or closing the safe, or an abnormal situation, users can obtain relevant information immediately, making it safer and more worry-free to use. Attached Figure Description

Vibration alarm. Detailed Implementation

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] like Figures 1 to 7 As shown, the structure of this device is as follows.

[0027] Door panel 1: A mechanism frame 110 and a shaft positioning sleeve 120 are fixedly connected, and a vibration alarm 13 is installed. The mechanism frame 110 has a guide positioning hole (not shown in the figure) on its right side that matches the side door bolt 61, and guide positioning holes (not shown in the figure) at its upper and lower ends that match the upper door bolt 62 and lower door bolt 63, respectively. The shaft positioning sleeve 120 is coaxial with the handle hole (not shown in the figure) on the door panel 1.

[0028] Lock plate 2: Fixedly installed on door panel 1, it has a positioning sleeve hole 21 that matches the shaft positioning sleeve 120, and is fixedly connected to a first guide boss 22, a second guide boss 23, a heavy lock pin seat 24, and a guide positioning block 25. The first guide boss 22 is provided with a first guide boss 221. The second guide boss 23 is provided with a second guide boss 231.

[0029] The guide positioning block 25 contains an anti-drill disc 26 and is equipped with a linkage pin guide groove 251 that matches the linkage pin 94, a rectangular through hole 252 that matches the connecting rod 93, and a hole for installing the anti-drill disc 26 (not shown in the figure). In the locked state, the anti-drill disc 26 is coaxial with the linkage pin 94, protecting the linkage pin 94 from attack and damage.

[0030] The locking pin seat 24 has a pin hole 241 adapted to the locking pin 10 and a limiting groove 242 adapted to the elastic cotter pin 101. A compression spring 102 and the locking pin 10 are sequentially installed in the pin hole 241. The elastic cotter pin 101 passes through the limiting groove 242 and is fixed in the corresponding hole (not shown in the figure) of the locking pin 10. The two are fixed together, restricting the axial movement of the locking pin 10 by the limiting groove 242.

[0031] Electric telescopic device 9: Fixedly installed on locking plate 2, equipped with telescopic rod 91, and fixedly connected with locking plates 92 symmetrically distributed vertically. Locking plate 92 is provided with locking hole 921.

[0032] A microcontroller is installed at the bottom of the safe. The microcontroller includes a power supply, a control board, a wireless signal receiver, and a wireless signal transmitter. The electric telescopic device is connected to the control board. An external signal controller is electrically connected to the wireless signal receiver and transmitter to control the operation of the electric telescopic device. The vibration alarm 13 is electrically connected to the control board on the microcontroller and is powered by the power supply.

[0033] In normal operation, the locking hole 921 accommodates the elastic cotter pin 101, constraining the re-locking pin 10 within the re-locking pin seat 24. The compression spring 102 is compressed, and the re-locking mechanism is locked. When the electric telescopic device 9 is attacked and damaged, the locking hole 921 disengages from the elastic cotter pin 101, the compression spring 102 rebounds, driving one end of the re-locking pin 10 to pop out of the re-locking pin seat 24, releasing (triggering) the re-locking mechanism. The re-locking mechanisms located at the upper and lower ends of the locking plate 2 are the upper re-lock and the lower re-lock, respectively, and their structures are symmetrical.

[0034] Linkage 93: It has a central hole 931 that matches the linkage pin 94, and symmetrically arranged slotted holes 932 that match the shaft screws 95. Linkage 93 is placed within the rectangular through hole 252 of the guide positioning block 25. The linkage pin 94 passes through the linkage pin guide groove 251 and is fixed within the central hole 931 of the linkage 93, the two being integrally connected. The linkage pin 94 moves horizontally left and right as the linkage 93 rotates. The shaft screws 95 pass through the slotted holes 932 and are fixed to the end of the telescopic rod 91 of the electric telescopic device 9. Linkage 93 moves in conjunction with the electric telescopic device 9.

[0035] The stroke of the electric telescopic device 9 corresponds to its open (link 93 extends outward) and closed (link 93 retracts inward) states. The two electric telescopic devices 9 are arranged horizontally and symmetrically with the center of the link 93. The lower electric telescopic device 9 serves as a backup and is activated in case of failure of the main electric telescopic device 9 (the upper one) to ensure remote operation.

[0036] The first switch bracket 111 and the second switch bracket 112 are fixedly installed on the lock plate 2. The first switch bracket 111 is equipped with a first micro switch 1131 and a second micro switch 1132, and the second switch bracket 112 is equipped with a third micro switch 1133.

[0037] Safe lock 8: Fixedly mounted on lock plate 2, equipped with a latch 81. A third switch touch panel 82 is fixedly connected to the end of the latch 81. When locked, the latch 81 extends, causing the third switch touch panel 82 to move down and press the third micro switch 1133 (power off). When unlocked, the latch 81 retracts, causing the third switch touch panel 82 to move up and disengage from the third micro switch 1133 (power on).

[0038] Upper slide plate 3: It is provided with a first vertical guide groove 31 that mates with the first guide boss 221, an upper drive groove 32 that mates with the linkage pin 94, a first upper bend stop 33 and a first lower bend stop 34, and is fixedly connected to an upper connecting angle iron 35. The upper connecting angle iron 35 is fixedly connected to an upper door bolt 62 and is equipped with a first switch touch panel 36.

[0039] The upper sliding plate 3 is located above the guide positioning block 25 and is positioned by the first guide boss 22, allowing it to move vertically up and down. The linkage pin 94 is located within the upper drive groove 32. The left and right movement of the linkage pin 94 acts on the upper drive groove 32, driving the upper sliding plate 3 to move up and down, thereby moving the upper door bolt 62 to the open or closed position. If the upper heavy lock is triggered, the heavy lock pin 10 blocks the first bend upper block 33; if the lower heavy lock is triggered, the heavy lock pin 10 blocks the first bend lower block 34; in both cases, the upper sliding plate 3 is prevented from moving down, i.e., the upper door bolt 62 is prevented from moving in the opening direction.

[0040] When the upper door bolt 62 moves up to the closed position, it causes the first switch touch panel 36 to press the first micro switch 1131 (power off); when the upper door bolt 62 moves down in the opening direction, it causes the first switch touch panel 36 to disengage from the first micro switch 1131 (power on).

[0041] The lower slide plate 4 is provided with a second vertical guide groove 41 that cooperates with the first guide boss 221, a lower drive groove 42 that cooperates with the linkage pin 94, a second upper bend stop 43 and a second lower bend stop 44, and is fixedly connected with a lower connecting angle iron 45 and a blocking square block 46.

[0042] The lower connecting angle iron 45 is fixed with the lower door bolt 63.

[0043] The lower slide plate 4 is located above the upper slide plate 3 and is positioned by the first guide boss 22, allowing it to move vertically up and down. The linkage pin 94 is located within the lower drive groove 42. The left and right movement of the linkage pin 94 acts on the lower drive groove 42, driving the lower slide plate 4 to move up and down, thereby causing the lower door bolt 63 to reach the open or closed position. If the upper locking mechanism is triggered, the locking pin 10 blocks the second bend upper block 43; if the lower locking mechanism is triggered, the locking pin 10 blocks the second bend lower block 44; in both cases, the lower slide plate 4 is prevented from moving upwards, i.e., the lower door bolt 63 is prevented from moving in the opening direction.

[0044] One end of the handle shaft 7 is fixed with a handle, and the other end passes through the door panel 1 and the shaft positioning sleeve 120. After the toggle block 71 is installed, it is fixed with a locking nut 72. A drive pin 711 is fixed on the toggle block 71, which can rotate with the handle shaft 7.

[0045] Horizontal slide plate 5: It is provided with a first horizontal guide groove 51 that cooperates with the first guide boss 221, a second horizontal guide groove 52 that cooperates with the second guide boss 231, a vertical groove 53 that is adapted to the drive pin 711, a vertical square groove 541 and a horizontal square groove 542 (the two intersect to form an inverted L shape) that are adapted to the blocking square block 46, a first clearance groove 55 (used to avoid the locking nut 72 when opening and closing the door), a second clearance groove 56 (used to avoid the linkage pin 94 when opening and closing the door) and a locking bend 57, a second switch touch panel 58 is installed, and a side door bolt 61 is fixedly connected.

[0046] The horizontal sliding plate 5 is located above the lower sliding plate 4 and is positioned by the first guide boss 22 and the second guide boss 23, allowing it to move horizontally left and right. In the locked state, the blocking square block 46 is located within the vertical square groove 541, preventing the horizontal sliding plate 5 from moving and thus preventing the side door bolt 61 from moving in the opening direction. When the upper door bolt 62 and the lower door bolt 63 are in the open position, the blocking square block 46 is located at the intersection of the vertical square groove 541 and the horizontal square groove 542, allowing the horizontal sliding plate 5 to move. When the handle shaft 7 is rotated, the drive pin 711 of the lever 71 acts on the vertical groove 53, driving the horizontal sliding plate 5 to move left and right, thereby moving the side door bolt 61 to the open or closed position. In addition, in the locked state, the latch 81 of the safe lock 8 blocks the lock bend 57, preventing the horizontal sliding plate 5 from moving and also preventing the side door bolt 61 from moving in the opening direction, achieving double locking of the side door bolt 61.

[0047] When the side door bolt 61 moves to the right to the closed position, it causes the second switch touch panel 58 to press the second micro switch 1132 (power off); when the side door bolt 61 moves to the left in the opening direction, it causes the second switch touch panel 58 to disengage from the second micro switch 1132 (power on).

[0048] Mechanism pressure plate 12: It is provided with a vertical blocking square groove 121 that is adapted to the blocking square block 46 and a horizontal blocking groove 122 that is adapted to the linkage pin 94.

[0049] The mechanism pressure plate 12 is located above the horizontal slide plate 5 and is fixedly installed on the first guide boss 22 and the second guide boss 23. The blocking square block 46 is located in the vertical blocking square groove 121, and the linkage pin 94 is located in the horizontal blocking groove 122.

[0050] The blocking square block 46 of the lower slide plate 4 is one of the mechanisms for locking the side bolt 61, and its movement is restricted by the vertical blocking square groove 121 of the mechanism pressure plate 12. The linkage pin 94 of the connecting rod 93 both drives and locks the upper bolt 62 and the lower bolt 63, and its movement is restricted by the linkage pin guide groove 251 of the guide positioning block 25 on the lock plate 2 and the horizontal blocking groove 122 of the mechanism pressure plate 12. This security protection mechanism design can effectively resist attacks on the side bolt 61, upper bolt 62 and lower bolt 63 by the tools allowed to break into high-security safes.

[0051] Door opening and closing operation: The on-site operator operates on the "operation display screen" of door panel 1, while the remote administrator operates on the "designated device" (such as a mobile phone, computer, etc.). The safe is equipped with a door status limit switch. When the door panel is closed, the limit switch is pressed (power off), and when door panel 1 is opened, door panel 1 is disengaged from the limit switch (power on).

[0052] Door opening procedure: The on-site operator issues an opening command, which is confirmed by the remote administrator, who then turns off the vibration alarm 13.

[0053] On-site personnel unlock the safe lock 8, the bolt 81 retracts, causing the third switch touch panel 82 to disengage from the third micro switch 1133 (powered on). The "Operation Display Screen" and "Designated Equipment" display "Unlocked".

[0054] When the remote administrator activates the electric telescopic device 9, the telescopic rod 91 extends outward, and the shaft screw 95 acts on the slot hole 932, driving the connecting rod 93 to rotate clockwise. The linkage pin 94, fixed to the center of the connecting rod 93, moves to the right accordingly. Simultaneously, the linkage pin 94 acts on the upper drive slot 32 of the upper slide plate 3 and the lower drive slot 42 of the lower slide plate 4, driving the upper slide plate 3 to move downward and the lower slide plate 4 to move upward. The upper and lower door bolts 62 and 63 are moved inward toward the mechanism frame 110 until they reach the open position. The first switch touch panel 36 on the upper slide plate 3 disengages from the first micro switch 1131 (powered on), and the "Operation Display" and "Designated Device" display "Open Upper and Lower Door Bolts".

[0055] The operator turns the handle in the direction of door opening, and the drive pin 711 of the toggle block 71 acts on the vertical groove 53 of the horizontal slide plate 5, driving the horizontal slide plate 5 to move to the left. The side door bolt 61 is driven to move inward to the inside of the mechanism frame 110 until it reaches the door opening position. The second switch touch panel 58 on the horizontal slide plate 5 disengages from the second micro switch 1132 (powered on), and "Open side door bolt" is displayed on the "Operation Display" and "Designated Equipment".

[0056] The on-site operator opens door panel 1, and the "Operation Display Screen" and "Designated Equipment" display "Door Open" ( Figure 5 , Figure 6 , Figure 7 ).

[0057] If the backup electric telescopic device 9 is activated, when the telescopic rod 91 extends outward, the shaft screw 95 acts on the slotted hole 932, driving the connecting rod 93 to rotate counterclockwise. The linkage pin 94 fixed in the center of the connecting rod 93 moves to the right, similarly driving the upper slide plate 3 to move down and the lower slide plate 4 to move up, so that the upper door bolt 62 and the lower door bolt 63 reach the open position.
