Description

Technical Field

[0001] This utility model relates to the field of security technology, and in particular to an access control security device. Background Technology

[0002] Currently, in access control and security systems, electronic sensing elements (such as reed switches and Hall effect sensors) are typically used to detect the position of the latch or door leaf in order to monitor the opening and closing status of access control systems. While this type of solution can achieve status monitoring, its reliability is highly dependent on the stability of the circuit and the continuity of power supply. In practical applications, electronic components are easily affected by external electromagnetic interference, aging circuits, poor contact, or power outages, leading to false alarms, missed alarms, or even complete failure, failing to accurately reflect the mechanical action of the lock. Especially in situations requiring high security levels, if the electronic monitoring link malfunctions, management personnel cannot accurately determine whether the access control has been illegally opened, posing a significant security risk. Therefore, how to stably and reliably transmit the action status of the lock shaft synchronously through a mechanical feedback mechanism has become a key technical problem that urgently needs to be solved in this field. Utility Model Content

[0003] The purpose of this invention is to provide an access control security device to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An access control security device includes a lock for controlling the opening and closing of the access control, the lock including a locking shaft capable of reciprocating in a horizontal direction and a power source providing the driving force for the reciprocating movement of the locking shaft;

[0006] The lock is mounted on a mounting plate, and the mounting plate is provided with a passive block that can reciprocate in the vertical direction. A linkage component is provided between the lock shaft and the passive block, and the linkage component can drive the passive block to move in the vertical direction while the lock shaft moves in the horizontal direction.

[0007] It also includes a security alarm component that is separate from the lock. The security alarm component is located below the lock and includes a spring and a non-self-locking button inside itself. The security alarm component also includes a feedback shaft that extends out of itself and is positioned toward the passive block. The feedback shaft can press the button under the push of the passive block to make it conduct and generate an alarm signal. Under normal conditions, the feedback shaft will move away from the button by the elastic force of the spring, so that the button is in the off state.

[0008] When the locking shaft moves toward the access control side and locks the access control, the passive block will not push the feedback shaft to press the button; when the locking shaft moves away from the access control side and unlocks the access control, the passive block will push the feedback shaft to press the button.

[0009] By adopting the above technical solution, the lock and security alarm components are set up separately, and the horizontal movement of the lock shaft drives the passive block to move vertically, thereby controlling the pressing state of the feedback shaft on the non-self-locking button, realizing a reliable mechanical feedback of the access control locking and unlocking states. This structure not only avoids problems such as electromagnetic interference, circuit aging, or power failure that may occur in electronic components during long-term use, but also ensures that the alarm signal can be accurately triggered when the lock shaft unlocks the access control, but not when it is locked, thus greatly improving the stability and anti-interference capability of the security system. At the same time, since the security alarm component and the lock are independent of each other, it is easy to maintain and replace them later without affecting the normal operation of the lock.

[0010] A further provision is that the linkage component includes a guide seat disposed on the mounting plate and movable in the horizontal direction, the locking shaft is fixed to the guide seat, and the output end of the power source is connected to the guide seat to provide driving force thereto;

[0011] The guide seat has a guide oblique hole, and the upper end of the passive block is fixedly provided with a guide plate. The guide plate is fixedly provided with a guide shaft that can extend into and be confined in the guide oblique hole on the side facing the mounting plate. As the guide seat moves horizontally, it can drive the guide shaft to move along the guide oblique hole.

[0012] By adopting the above technical solution, the guide shaft slides in the guide inclined hole, which can smoothly convert the horizontal reciprocating movement of the lock shaft into the vertical movement of the passive block. This not only realizes the directional conversion of motion, but also ensures the reliable and stable linkage between the lock shaft and the passive block.

[0013] A further configuration is that two vertical first guide rails are fixedly mounted on the mounting plate, with the two first guide rails spaced apart, and the passive block is slidably mounted on the two first guide rails.

[0014] By adopting the above technical solution, the vertical displacement of the passive block can be effectively limited, ensuring its smooth movement under the drive of the linkage components.

[0015] A further configuration is that the two ends of the guide oblique hole are a low end and a high end, respectively, and the low end is located near the access control side. The low end and the high end are connected by an oblique connecting section, so that the guide shaft can change its position in the vertical direction along the oblique connecting section during horizontal movement.

[0016] By adopting the above technical solution, and by setting the guide oblique hole to include a low end, a high end, and an oblique connecting section, the guide shaft can generate vertical displacement along the oblique connecting section during horizontal movement, thereby accurately controlling the lifting and lowering of the passive block.

[0017] A further provision is that the lower end and the higher end are connected to the oblique connecting segment via a horizontally extending transition segment.

[0018] By adopting the above technical solution, the guide shaft can stop at the horizontal transition section when it reaches the end of the stroke, thereby ensuring that the passive block remains stable at the limit position of the stroke.

[0019] A further configuration is that the passive block has a downwardly extending passive protrusion that drives the feedback shaft.

[0020] A further configuration includes a housing, within which two partitions are fixedly installed, forming a groove between them. The bottom end of the feedback shaft is located in the groove, and an opening is provided at the top of the housing for the top end of the feedback shaft to extend out of the housing. A trigger push block is movably installed in the groove, and a trigger rod is fixedly installed on one side of the trigger push block. The button is fixed inside the housing and corresponds to the position of the trigger rod. The trigger push block can move downward under the push of the feedback shaft, causing the trigger rod to press the button to activate it and generate an alarm signal.

[0021] The spring is located in the slot and between the trigger push block and the bottom of the slot. The elastic force of the spring pushes the trigger push block upward, causing the trigger rod to move away from the button.

[0022] By adopting the above technical solution, two partitions are set inside the housing to form a groove, and a trigger push block and a spring are movably set in it, so that the downward action of the feedback shaft can be indirectly transmitted to the button through the trigger push block; the reset action of the spring ensures that the feedback shaft automatically disengages from the button when there is no external force, so that the button remains in the off state. This not only improves the service life of the button, but also ensures the clarity and reliability of each button trigger.

[0023] A further feature is that the end of the trigger push block facing the spring is fixedly provided with an embedded protrusion, which is embedded in the spring for limiting its position.

[0024] By adopting the above technical solution, the spring can be effectively prevented from shifting during use.

[0025] A further provision is that an inner fixing block is fixedly installed inside the housing, and the inner fixing block has an inner channel with a connecting opening and a partition groove, and the inner channel matches the feedback shaft.

[0026] By adopting the above technical solution, the movement of the feedback shaft is effectively limited through the internal channel.

[0027] In summary, this utility model has the following beneficial effects: by separating the lock and the security alarm components, and by utilizing the mechanical linkage structure between the lock shaft, the passive block, and the feedback shaft, the feedback shaft is accurately pushed to push the button to generate an alarm signal when the lock shaft unlocks the access control, while keeping the button off when locked. This achieves stable and reliable feedback on the access control status, effectively avoiding problems such as electronic components being susceptible to interference, aging, or power failure, and significantly improving the anti-interference capability and operational stability of the security system.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1-3 As shown;

[0034] This embodiment discloses an access control security device, the core of which lies in achieving the association triggering of access control status and security alarm through a clever mechanical linkage structure. Specifically, it includes a lock for controlling the opening and closing of the access control unit. The lock itself includes a locking shaft 11 capable of reciprocating horizontally and a power source 12 providing the reciprocating driving force for the locking shaft 11. The locking shaft 11 can extend into the access control unit to lock it. The power source 12 is preferably a cylinder. The lock is fixedly mounted on a mounting plate 21, which also has a passive block 22 capable of reciprocating vertically. A linkage component is provided between the locking shaft 11 and the passive block 22, which can drive the passive block 22 to move vertically while the locking shaft 11 moves horizontally. To achieve security monitoring functionality, a security alarm component, separate from the lock, is included. This component is located directly below the lock and contains a spring 32 and a non-self-locking button 33. The alarm component also includes a feedback shaft 34 extending from the internal housing 31 and facing the passive block 22. The feedback shaft 34, when pushed downwards by the passive block 22, presses the button 33, activating it and generating an alarm signal. Normally, the feedback shaft 34 returns to its original position under the elastic force of the spring 32, moving away from the button 33 and deactivating it. The operating logic is as follows: When the lock shaft 11 moves towards the access control side and locks the access control, the passive block 22 is in a position where it will not push the feedback shaft 34 to press the button 33. When the lock shaft 11 moves away from the access control side and unlocks the access control, the passive block 22 moves downwards, pushing the feedback shaft 34 to press the button 33, thus triggering the security alarm.

[0035] Furthermore, the linkage component for connecting the locking shaft 11 and the driven block 22 includes a guide seat 41 mounted on the mounting plate 21 and movable in the horizontal direction. The mounting plate 21 is equipped with a horizontal second guide rail (not shown in the figure) to guide and limit the guide seat 41. The locking shaft 11 is fixed on the guide seat 41, and the output end of the power source 12 is also connected to the guide seat 41 to provide driving force. A guide oblique hole 42 is provided on the guide seat 41, and a guide plate 43 is fixedly provided at the upper end of the driven block 22. A guide shaft 44 is fixedly provided on the side of the guide plate 43 facing the mounting plate 21, which can extend into and be limited in the guide oblique hole 42. In this way, as the guide seat 41 moves horizontally, it can drive the guide shaft 44 to move along the guide oblique hole 42, thereby converting the horizontal movement of the locking shaft 11 into the vertical movement of the driven block 22. To ensure the smooth movement of the passive block 22, two vertical first guide rails 51 are fixedly installed on the mounting plate 21. These two first guide rails 51 are arranged parallel to each other at intervals, and the passive block 22 is slidably set between the two first guide rails 51, ensuring precise guidance for its vertical movement.

[0036] Furthermore, the two ends of the guide oblique hole 42 are a lower end 61 and a higher end 62, with the lower end 61 located closer to the access control. The lower end 61 and the higher end 62 are connected by an oblique connecting section 63, allowing the guide shaft 44 to undergo vertical position changes along the oblique connecting section 63 during horizontal movement. To optimize the smoothness of the movement, the lower end 61 and the higher end 62 are connected to the oblique connecting section 63 by a horizontally extending transition section 64. This allows the guide shaft 44 to pause briefly in the horizontal transition section 64 at the beginning and end of the movement of the locking shaft 11, ensuring that the passive block 22 remains stable at the end of its stroke. The passive block 22 itself has a downwardly extending passive protrusion 221, which precisely pushes the feedback shaft 34 below.

[0037] The security alarm component specifically includes a housing 31. Two parallel, spaced-apart partitions 71 are fixedly installed inside the housing 31, forming a groove 72 between them. The bottom end of the feedback shaft 34 is located in this groove 72. An opening 73 is provided at the upper end of the housing 31 for the top end of the feedback shaft 34 to extend out of the housing 31. A trigger push block 81 is movably installed in the groove 72. A trigger rod 82 is fixedly installed on one side of the trigger push block 81. A button 33 is fixed inside the housing 31 and corresponds to the position of the trigger rod 82. Thus, the trigger push block 81 can move downwards under the push of the feedback shaft 34, causing the trigger rod 82 to press the button 33, activating it and generating an alarm signal. A spring 32 is located in the groove 72, between the trigger push block 81 and the bottom of the groove 72. The elastic force of the spring 32 pushes the trigger push block 81 upwards to reset, causing the trigger rod 82 to move away from the button 33. To ensure the stability of the spring 32, an embedded protrusion 83 is fixedly provided on one end of the trigger push block 81 facing the spring 32. The embedded protrusion 83 is embedded inside the spring 32 for effective limiting. In addition, an inner fixing block 91 is fixedly provided inside the housing 31. The inner fixing block 91 has an inner channel that connects the opening 73 and the slot 72. This inner channel matches the diameter of the feedback shaft 34, providing precise guidance for the up and down movement of the feedback shaft 34.

[0038] In actual operation, when the access control needs to be locked, the power source 12 drives the guide seat 41 to move horizontally towards the access control, and the locking shaft 11 fixed on the guide seat 41 extends to achieve locking. At this time, the guide oblique hole 42 on the guide seat 41 moves accordingly. Since the guide shaft 44 is confined within the guide oblique hole 42, as the guide seat 41 moves, the guide shaft 44 will move along the guide oblique hole 42 to the high end 62, so that the passive block 22 is in an upward position as a whole, and the passive protrusion 221 at its lower end will not touch the feedback shaft 34 below, so the security alarm component remains silent. When the access control needs to be unlocked, the power source 12 drives the guide seat 41 to move horizontally away from the access control, and the locking shaft 11 retracts to unlock. At this time, the guide oblique hole 42 moves in the opposite direction with the guide seat 41, and the guide shaft 44 moves from the high end 62 along the oblique connecting section 63 to the low end 61. The guide shaft 44 drives the entire passive block 22 to move downward along the first guide rail 51. The passive protrusion 221 at the lower end of the passive block 22 pushes the top of the feedback shaft 34 downward, causing the feedback shaft 34 to overcome the elastic force of the spring 32 and move downward. This pushes the trigger push block 81 downward, and the trigger rod 82 on the side of the trigger push block 81 will squeeze the non-self-locking button 33 to make it conduct momentarily, generating an alarm signal that is transmitted to the security host to realize the door opening alarm function. When the locking shaft 11 extends again to lock, the passive block 22 moves upward to release the pressure on the feedback shaft 34, the spring 32 pushes the trigger push block 81 and the feedback shaft 34 to reset, the button 33 is disengaged, and the alarm signal stops. This purely mechanical linkage structure design ensures the reliability and real-time nature of alarm triggering, and the security alarm components are set separately from the locks, making it easy to maintain and replace them independently.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
