Description

Technical Field

[0001] This utility model relates to the field of outdoor cabinet protection technology, and in particular to a hidden lock mechanism for outdoor cabinets. Background Technology

[0002] With the rapid development of information technology, outdoor server racks, as key carriers of communication equipment, power facilities, and other critical infrastructure, are receiving increasing attention for their security and reliability. Traditional outdoor server rack lock solutions often focus on basic security functions; however, in practical applications, these locks have some significant shortcomings: First, existing rack locks are typically designed to be highly visible, which not only affects the overall aesthetics of the rack but also provides a clear target for potential vandals, increasing the risk of unauthorized entry. Second, many traditional locks rely on a single locking point. This design is prone to structural weaknesses when facing complex environmental conditions and high-intensity usage demands, leading to reduced security. Furthermore, the lack of an effective synchronized control mechanism makes operating multiple independent locks time-consuming and inconvenient for large racks or those requiring multiple locking points, significantly diminishing the user experience.

[0003] In order to solve the above-mentioned technical problems, this utility model designs an outdoor cabinet hidden lock mechanism. Utility Model Content

[0004] This utility model provides a hidden lock mechanism for outdoor cabinets, which aims to solve the problems of existing locks being conspicuous, having low security due to a single locking point, and lacking an effective synchronous control mechanism, resulting in inconvenient operation.

[0005] An outdoor cabinet concealed lock mechanism includes two lock bodies, each lock body comprising a lock body shell, a pull rod rotatably mounted inside the lock body shell, and a lock tongue; a buckle fixedly mounted on the cabinet door frame, having a stop shaft on it; a first pull cable and a second pull cable respectively connected to the pull rods of the two lock bodies; a pull cable adapter plate fixedly connected to the free ends of the first and second pull cables; and a main pull cable, one end connected to the pull cable adapter plate and the other end connected to the unlocking handle; wherein, the lock tongue has a locking port that cooperates with the stop shaft of the buckle, and the pull rod drives the locking port of the lock tongue to disengage or engage with the stop shaft by rotation, thereby unlocking or locking the lock body.

[0006] Based on the above technical solution, the lock body shell is provided with a pull rod pivot and a latch pivot; the pull rod is rotatably connected to the lock body shell through the pull rod pivot, and its end is provided with a pull rod locking block; the latch is rotatably connected to the lock body shell through the latch pivot, and its end is provided with a latch locking block.

[0007] Based on the above technical solution, the pull rod and the locking tongue are respectively provided with a pull rod torsion spring and a locking tongue torsion spring for a reset function.

[0008] Furthermore, the lock body housing is also provided with a limiting top plate to limit the rotation angle of the lock tongue.

[0009] Preferably, the retaining shaft of the buckle is a cylindrical structure, and its axis is perpendicular to the movement direction of the locking opening of the locking tongue.

[0010] Beneficial effects Compared with existing technologies, the advantages of this invention are as follows: Firstly, by utilizing a pull-wire system, synchronous control of the two lock bodies is achieved, allowing users to complete the unlocking or locking process simply by operating one unlocking handle, greatly simplifying the operation process and improving convenience and efficiency. Secondly, by designing the lock bodies as concealed, the risk of the locks being easily discovered and damaged is reduced, improving the overall security of the cabinet. Simultaneously, the dual-lock body design provides an additional layer of security. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] like Figure 1 and Figure 2 As shown, an outdoor cabinet concealed lock mechanism includes two lock bodies 1, each lock body 1 including a lock body housing 11, a pull rod 12 rotatably installed in the lock body housing 11, and a lock tongue 13; The latch 2 is fixedly mounted on the cabinet door frame and has a stop shaft 21 on it. The latch 13 has a locking port 130 that engages with the stop shaft 21 of the latch 2. The pull rod 12 rotates to drive the locking port 130 of the latch 13 to disengage from or engage with the stop shaft 21, thereby unlocking or locking the lock body. By designing the pull rod 12 and the latch 13 to be rotatably mounted within the lock body housing 11, a complex locking mechanism can be implemented in a small space. For example, the latch 13 can precisely engage with the stop shaft 21 on the latch 2, providing additional security and preventing unauthorized opening.

[0017] The stop shaft 21 of the latch 2 has a cylindrical structure, and its axis is perpendicular to the movement direction of the locking opening 130 of the latch 13. This design ensures that the stop shaft provides a stable and uniform contact surface when the latch enters or exits the locking position. This helps prevent locking failure or instability caused by angular mismatch, thus improving the reliability of the lock.

[0018] Two lock bodies 1 are installed on the outdoor cabinet, one above the other, with latches 2 installed at opposite positions on the cabinet door frame. By placing the lock bodies at different heights on the cabinet door, the difficulty of unauthorized entry is increased. Even if an attacker manages to break one lock body, they will still need to contend with the protection of the other. The vertically arranged lock bodies 1 can more evenly distribute the pressure when the door is closed, preventing damage to the door frame or lock body due to excessive force at a single point, thus extending the service life of the equipment.

[0019] The first pull cable 3 and the second pull cable 4 are respectively connected to the pull rods 12 of the two lock bodies 1; the pull cable adapter plate 5 is fixedly connected to the free ends of the first pull cable 3 and the second pull cable 4; by connecting the first pull cable 3 and the second pull cable 4 together through the pull cable adapter plate 5, synchronous control of the two lock bodies 1 can be achieved. It also includes a main pull cable 6, one end of which is connected to the pull cable adapter plate 5, and the other end is connected to the unlocking handle 7; The unlocking handle 7 drives the pull wire adapter plate 5 to move horizontally through the pull of the main pull wire 6, and then drives the pull rods 12 of the two lock bodies 1 to rotate synchronously through the first pull wire 3 and the second pull wire 4.

[0020] This means that when the unlocking handle 7 is operated, the main pull cable 6 will pull the pull cable adapter plate 5, which in turn will drive the pull rods 12 of both lock bodies simultaneously via the first pull cable 3 and the second pull cable 4. This ensures that both lock bodies can be unlocked or locked at the same time, improving the reliability and consistency of the system.

[0021] The first pull wire 3, the second pull wire 4, and the main pull wire 6 are steel wire sleeve pull wires. The steel wire sleeve pull wire includes a Teflon sleeve, a steel wire, and a connecting buckle. The steel wire is fitted with a Teflon sleeve, and the two ends of the steel wire are fixedly connected to the connecting buckle.

[0022] The steel wire, as the core material, provides high strength and excellent tensile properties, ensuring it won't easily break or deform during long-term use. This is crucial for locking mechanisms that require frequent operation or withstand significant external forces. The Teflon tubing has an extremely low coefficient of friction and self-lubricating properties, allowing the steel wire to move more smoothly within it, reducing operating resistance caused by friction, and improving the feel and stability of operation. The Teflon tubing is not only wear-resistant but also possesses excellent chemical stability and waterproof / dustproof capabilities, effectively protecting the internal steel wire from external environmental influences such as moisture, dust, and other corrosive substances, thereby extending the service life of the entire pull cable system.

[0023] The use of connecting clips allows for easy installation and removal of the cable, facilitating later inspection and maintenance. If a part needs replacement or repair, simply unfasten the corresponding connecting clip; no major adjustments to the entire system are required.

[0024] like Figures 3 to 5As shown, the lock body housing 11 is provided with a pull rod pivot 113 and a lock tongue pivot 114; The pull rod 12 is rotatably connected to the lock body shell 11 via the pull rod pivot 113, and its end is provided with a pull rod locking block 121; the pull rod locking block 121 and the lock tongue locking block 131 abut against each other in the locked state to form a linkage structure.

[0025] The latch 13 is rotatably connected to the lock body shell 11 via a latch pivot 114, and its end is provided with a latch block 131. The pull rod 12 and the latch 13 are respectively provided with a pull rod torsion spring 115 and a latch torsion spring 116 for a reset function.

[0026] The lock body shell 11 is also provided with a limiting top plate 112, which is used to limit the rotation angle of the lock tongue 13.

[0027] In locked state: like Figure 6 As shown, in the initial position: the latch 13, under the action of the latch torsion spring 116, always tends to spring upward, while the lever 12, under the action of the lever torsion spring 115, exerts a force pressing against the latch 13. The latch 13 is blocked by the lever catch 121 of the lever 12, and the locking port 130 is in a low position. The locking port 130 is located inside the lock body housing 11.

[0028] Unlocking the working process: Operating the unlocking handle 7: When the user turns the unlocking handle 7, the pull cable adapter plate 5 is pulled to move horizontally through the main pull cable 6, and the first pull cable 3 and the second pull cable 4 simultaneously pull the pull rods 12 of the two lock bodies 1.

[0029] like Figure 7 As shown, the lever disengages from the latch: the lever 12 rotates counterclockwise around the lever pivot 113, and the lever locking block 121 disengages from the latch locking block 131.

[0030] Locking tongue 13 pops up to unlock: Locking tongue 13 pops up quickly under the action of locking tongue torsion spring 116, locking port 130 separates from stop shaft 21, and cabinet door unlocks.

[0031] Lock operation: Method 1 (Direct Press-in Locking): When closing the cabinet door, the stop shaft 21 is directly pressed into the locking port 130 of the latch 13. At this time, external force forces the latch 13 to move downward against the elastic force of the latch torsion spring 116, and the locking port 130 engages with the stop shaft 21. At the same time, the pull rod block 121 of the pull rod 12 still abuts against the latch block 131 to prevent the latch from springing back.

[0032] Method 2 (Pre-release Locking): If the bolt position needs to be adjusted, the unlocking handle 7 can be operated to pull the pull cable adapter plate 5 through the main pull cable 6, simultaneously pulling the first pull cable 3 and the second pull cable 4, driving the pull rod 12 to rotate around the pull rod pivot 113. The pull rod locking block 121 disengages from the bolt locking block 131, and the bolt 13 springs up under the action of the bolt torsion spring 116, fully opening the locking port 130. At this time, after pressing in the stop shaft 21 and releasing the handle, the pull rod 12 returns to its original position under the action of the pull rod torsion spring 115, and once again presses against the bolt locking block 131, completing the locking.

[0033] Reset and Limit Protection Automatic reset: After releasing the unlocking handle 7, the lever 12 rotates and resets under the action of the lever torsion spring 115, the lever block 121 presses against the latch block 131 again, and the latch 13 returns to the lockable state.

[0034] Function of limiting top plate 112: The limiting top plate 112 inside the lock body shell 11 limits the rotation angle of the lock tongue 13 to avoid structural damage due to excessive displacement.

[0035] like Figure 8 As shown, a lock body assembly box 10 is provided outside the lock body 1. The lock body assembly box 10 is screwed to the rack, and a cable pass-through hole 101 is provided on the lock body assembly box 10. The lock body assembly box 10 provides an additional physical protective layer for the lock body, which can effectively prevent damage to the lock body caused by external environmental factors such as moisture, dust and mechanical impact, thereby extending the service life of the lock body. Directly connecting the lock body assembly box 10 to the rack with screws makes the installation process of the entire lock mechanism simpler and faster. This method not only provides a stable installation foundation but also facilitates the operation when adjusting or replacing the lock body later.

[0036] like Figure 9 As shown, when using it: Install the lock body assembly box 10: Select a suitable location on the cabinet door and drill holes using a drilling tool. Secure the lock body assembly box 10 to the cabinet door with screws, ensuring its stability. Note that the lock body assembly box has a cable pass-through hole 101 for subsequent wiring.

[0037] Install lock body 1: Install the two lock bodies 1 into their respective lock body assembly boxes 10. Adjust the pull rod 12 and the latch 13 so that they can work normally under the action of the pull rod torsion spring 115 and the latch torsion spring 116, and that the pull rod locking block 121 and the latch locking block 131 abut against each other in the locked state to form a linkage structure.

[0038] Install buckle 2: Based on the position of lock body 1, install buckle 2 at the corresponding position on the cabinet door frame, ensuring that the stop shaft 21 on it is a cylindrical structure and that its axis is perpendicular to the movement direction of the locking port 130 of the lock tongue 13.

[0039] Connecting the pull cable system: Connect the first pull cable 3 and the second pull cable 4 to the pull rods 12 of the two lock bodies 1 respectively. Use the pull cable adapter plate 5 to fix the free ends of the first pull cable 3 and the second pull cable 4 together. Connect one end of the main pull cable 6 to the pull cable adapter plate 5 and the other end to the unlocking handle 7.

[0040] Wiring arrangement: The wiring system is routed through the wire hole 101 on the lock body assembly box 10 to ensure that the wiring is neat and orderly and to avoid damage caused by excessive bending or friction.

[0041] The "concealed" nature of the hidden lock mechanism is primarily achieved by integrating the lock body and its related components into a closed assembly box, and using a specially designed pull-wire system for connection and operation. This achieves the goal of effectively concealing the lock without affecting its normal function. This design not only enhances the overall aesthetics of the cabinet, but more importantly, it improves security because the lock is difficult to detect, reducing the possibility of unauthorized opening.

[0042] It should be noted that the lock body 1 and the buckle 2 in this embodiment are general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0043] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
