Description

Technical Field

[0001] This utility model relates to the field of security access control technology, specifically a dustproof building security access control device. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of people's living standards, the requirements for the safety and comfort of living and working environments are increasing. As an important place for people's daily activities, the completeness of the security system of buildings is directly related to the life and property safety of residents and staff. As a key component of building security systems, access control devices bear the important responsibility of restricting unauthorized personnel from entering and ensuring the security of the building. At the same time, with the increasing prominence of environmental problems, the impact of dust and other pollutants on access control devices has gradually attracted attention. Therefore, dustproof building security access control devices have emerged on the market.

[0003] Currently, common dustproof building security access control devices mainly consist of an access control host, card reader, door lock, dustproof mechanism, and control system. The access control host handles data processing and command transmission, the card reader identifies personnel, and the door lock controls the door's opening and closing based on the host's commands. The dustproof mechanism primarily consists of a fan and a dust cover. The cover blocks dust falling from above, reducing dust accumulation on the device's exterior. The fan regularly cleans the device's exterior, minimizing the impact of dust on the user experience. The control system integrates all components to achieve intelligent access control management. In terms of security functions, existing access control devices offer multiple identification methods, such as card swiping, password input, fingerprint recognition, and facial recognition, effectively preventing unauthorized personnel from entering the building.

[0004] However, the aforementioned dustproof building security access control devices still have certain problems in actual use. For example, some users will directly slap their access cards onto the card reader when swiping their cards, which will cause some damage to the internal chips and modules of the card reader. The card reader is very easy to be damaged after being slapped repeatedly. If some users in the building have the habit of slapping their access cards onto the card reader, the lifespan of the access control device's card reader will be reduced. Therefore, it is urgent to improve the existing dustproof building security access control devices. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a dustproof building security access control device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof building security access control device, comprising a device body and a card reader panel disposed within the device body, wherein the device body is provided with a dustproof mechanism;

[0007] The device body has a protective plate slidably installed on its outer wall to protect the card reader panel. The top outer corner of the protective plate is designed with an angle. A limiting rod corresponding to the protective plate is slidably installed inside the device body. A spring corresponding to the protective plate is sleeved on the outer wall of the limiting rod to reset the protective plate.

[0008] The device body is provided with a limiting mechanism to restrict the sliding trajectory of the protective plate. When the protective plate slides into the device body, the limiting mechanism is used to restrict the protective plate to slide only to the state of being in contact with the outer wall of the card reader panel.

[0009] The outer wall of the protective panel is equipped with a protective mechanism that catches the access card during the access control process, preventing the access card from being accidentally dropped.

[0010] By adopting the above technical solutions, the product is guaranteed to have functions such as dust prevention, protection of the card reader panel, restriction of the sliding of the protective plate, and prevention of access cards from falling out, ensuring that the product can effectively solve the problems existing in the current access control device.

[0011] Furthermore, the outer wall of the device body is provided with a mounting groove for mounting a card reader panel, and the protective plate is slidably connected to the mounting groove.

[0012] By adopting the above technical solution, the sliding of the protective plate has a stable track, which facilitates the effective protection of the card reader panel.

[0013] Furthermore, the dustproof mechanism includes a dust cover installed on the outer wall of the device body, and a miniature fan for cleaning the surface of the device body is installed on the inner wall of the top of the dust cover.

[0014] By adopting the above technical solutions, the impact of dust on access control devices can be effectively reduced.

[0015] Furthermore, the limiting mechanism includes multiple sets of transmission blocks symmetrically installed on the outer wall of the protective plate, and a limiting groove opened on the outer wall of the device body and slidably connected to the transmission blocks. When the transmission block slides to a state of contact with the limiting groove, the inner wall of the protective plate is in contact with the outer wall of the card reader panel.

[0016] By adopting the above technical solution, the sliding trajectory of the protective plate is precisely controlled by limiting the sliding of the transmission block, ensuring that the protective plate can accurately slide to the position where it is in contact with the outer wall of the card reader panel. This ensures that the card reader panel can read the access card information normally during card swiping operations, while also preventing the card reader panel from being damaged due to excessive sliding of the protective plate, thus improving the stability and reliability of the access control device.

[0017] Furthermore, the limiting rod and the spring on its outer wall are both connected to the transmission block, and the inner wall of the device body is equipped with a storage groove corresponding to the spring.

[0018] By adopting the above technical solution, the limiting rod and spring can work together with the transmission block during the sliding process of the protective plate. The spring stores and releases elastic potential energy to realize the automatic reset function of the protective plate.

[0019] Furthermore, the protective mechanism includes a baffle installed on the outer wall of the transmission block, and the inner wall of the baffle does not contact the protective plate, and multiple sets of blocks that are attached to the outer wall of the protective plate are installed at equal intervals on the inner wall of the baffle.

[0020] By adopting the above technical solutions, the access control cards are effectively prevented from falling and being damaged, improving the user experience and ensuring the security of the access control cards, reflecting the humanized and practical design of the product.

[0021] Furthermore, the cross-section of the block is designed as an isosceles triangle, and the spacing between multiple sets of blocks is less than the length of the access card.

[0022] By adopting the above technical solution, the isosceles triangular design of the baffle facilitates the sliding of dust, preventing dust from accumulating between the baffle and the protective plate and affecting the normal operation of the device.

[0023] In summary, the present invention has the following main advantages:

[0024] This utility model incorporates a dustproof mechanism. The dustproof cover and miniature fan work together to effectively block and clean dust. The angled design at the top of the protective plate prevents dust accumulation. Furthermore, with the assistance of a limiting mechanism, the protective plate not only protects the card reader panel from dust when not in use, but also cushions the impact of access cards during use, reducing damage and extending its lifespan. The limiting mechanism precisely controls the sliding trajectory of the protective plate, ensuring stable and accurate card-swiping operations. The protective plate also automatically resets for user convenience. The baffle and specially designed stop in the protective mechanism can catch accidentally dropped access cards, preventing damage. The shape of the stop facilitates dust sliding off, preventing interference with device operation. Overall, this design comprehensively enhances the practicality, security, and reliability of the access control device. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] This utility model focuses on solving the problems of easy damage to card readers and easy loss of access cards in existing dustproof building security access control devices. Through a series of uniquely designed components, it achieves effective protection of the card reader panel, reduces the risk of access cards falling off, and enhances the dustproof function, thereby improving the overall performance of the access control device.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Dustproof building security access control devices, such as Figure 1 - Figure 4 As shown, it mainly consists of a device body 1 and a card reader panel 2. The device body 1 is equipped with a dustproof mechanism, a limit mechanism and a protective mechanism. The mechanisms work together to ensure the normal operation of the access control device.

[0034] The device body 1 serves as the basic carrier of the entire access control device, providing installation positions and support for other components. Its outer wall has an installation groove 21 for installing the card reader panel 2. At the same time, the device body 1 is also the installation base for components such as dust cover 3, limit rod 6, and limit groove 51, bearing and integrating various components to ensure the structural integrity of the entire device.

[0035] The card reader panel 2 in this utility model is responsible for reading access control card information and is a key component for realizing access control function. It is installed in the mounting slot 21 of the device body 1 and works with the access control card to complete the identity recognition work.

[0036] This utility model also provides a dustproof mechanism, which mainly includes:

[0037] The dust cover 3 installed on the outer wall of the device body 1 serves to block dust, reduce the amount of external dust falling directly onto the outer wall of the device body 1, and reduce the impact of dust on the user experience.

[0038] The miniature fan 31 installed on the inner wall of the top of the dust cover 3 can blow off the dust on the surface of the device body 1 when it is turned on periodically, keeping the device clean. Due to the angled design of the outer corner of the top of the protective plate 4, the air blown by the miniature fan 31 flows outward along the angle, preventing dust from accumulating on the top of the protective plate 4, and further enhancing the dustproof effect.

[0039] The protective plate 4, which is slidably connected to the mounting groove 21, is mainly used to protect the card reader panel 2. When not in use, it covers the card reader panel 2 under the action of the limit rod 6 and the spring 7 to prevent dust, flying lint, etc. from damaging the card reader panel 2. When in use, the user pushes the protective plate 4 into the device body 1 to slide it inward. Even if the access card is slapped onto the protective plate 4, it can effectively reduce the damage to the card reader panel 2 and extend the service life of the card reader panel 2.

[0040] This utility model also discloses a limiting mechanism, which mainly includes:

[0041] The transmission blocks 5 are symmetrically installed on the outer wall of the protective plate 4. The transmission blocks 5 are slidably connected to the limiting groove 51. When the protective plate 4 slides, the transmission blocks 5 are driven to move within the limiting groove 51, thereby limiting the sliding trajectory of the protective plate 4. At the same time, the transmission blocks 5 are connected to the limiting rod 6 and the spring 7. During the sliding process of the protective plate 4, the limiting rod 6 moves synchronously and compresses the spring 7, storing elastic potential energy.

[0042] The limiting groove 51 opened on the outer wall of the device body 1 cooperates with the transmission block 5 to precisely limit the sliding path of the transmission block 5, thereby ensuring that the protective plate 4 can only slide to the state of being in contact with the outer wall of the card reader panel 2, ensuring the accuracy and stability of the card swiping operation, while preventing the protective plate 4 from sliding excessively and causing collision damage to the card reader panel 2.

[0043] It also includes a limit rod 6 and a spring 7;

[0044] The limiting rod 6 is slidably installed inside the device body 1, and the outer wall is fitted with a spring 7, both of which are connected to the transmission block 5. The spring 7 is compressed when the protective plate 4 is pushed, storing elastic potential energy. After the user swipes the card to release the protective plate 4, the spring 7 releases the elastic potential energy, pushes the limiting rod 6 and the transmission block 5 to reset, and drives the protective plate 4 back to its initial position, realizing the automatic reset function of the protective plate 4. The storage groove 71 on the inner wall of the device body 1 is used to install the spring 7, which plays a role in positioning and protecting the spring 7, ensuring that the spring 7 works normally.

[0045] This utility model also discloses a protective mechanism, which mainly includes:

[0046] The baffle 8 installed on the outer wall of the transmission block 5 does not contact the protective plate 4. It mainly cooperates with the block 9 to catch the access card that is accidentally dropped. When the user swipes the card, if the access card is accidentally dropped, the baffle 8 will cooperate with the block 9 to catch the access card in time and prevent the access card from being damaged.

[0047] The blocks 9 are installed at equal intervals on the inner wall of the baffle 8 and attached to the outer wall of the protective plate 4. The cross-section is an isosceles triangle design, and the distance between multiple blocks 9 is less than the length of the access card. At the same time, the isosceles triangle design of the blocks 9 allows dust to fall down along the slope, preventing dust from accumulating between the baffle 8 and the protective plate 4 and affecting the normal use of the device.

[0048] The working principle of this utility model is as follows: When the access control device is not in use, the protective plate 4 is located outside the card reader panel 2 under the elastic force of the spring 7 on the outer wall of the limit rod 6, which protects the card reader panel 2. At this time, the dust cover 3 covers the device body 1, and the micro fan 31 can be started periodically according to the setting to blow off the dust on the surface of the device body 1, reduce dust accumulation, and keep the device clean.

[0049] Meanwhile, due to the angled design of the outer corner of the top of the protective plate 4, the air blown out by the micro fan 31 will flow outward along the angled top of the protective plate 4, preventing the dust blown down from accumulating on the top of the protective plate 4.

[0050] When using the access control system, the user places the access card against the protective plate 4 and pushes the protective plate 4 towards the device body 1. As the protective plate 4 slides, it drives the transmission block 5 connected to it to slide within the limiting groove 51 on the outer wall of the device body 1. The limiting groove 51 restricts the sliding trajectory of the transmission block 5, thereby restricting the sliding trajectory of the protective plate 4, ensuring that the protective plate 4 can only slide to the state of being in contact with the outer wall of the card reader panel 2. This effectively reduces damage to the card reader panel 2 even if the user slaps the access card onto the protective plate 4, effectively extending the service life of the access control device.

[0051] Furthermore, during the sliding of the protective plate 4, the limiting rod 6 will move together with the transmission block 5, and the spring 7 will begin to compress under the pressure of the transmission block 5, so that the spring 7 stores elastic potential energy.

[0052] Once the protective plate 4 is slid into place, the card reader panel 2 will recognize the access card, thus completing the card swiping operation;

[0053] Since the inner wall of the baffle 8 does not contact the protective plate 4, and the baffle blocks 9 are installed at equal intervals on the inner wall of the baffle 8 and are attached to the outer wall of the protective plate 4, if the access card is accidentally dropped when the user swipes the card, the baffle 8 can catch the access card; and the distance between the multiple sets of baffle blocks 9 is less than the length of the access card, which allows the baffle blocks 9 to block the access card and prevent the access card from falling through the gap between the baffle 8 and the protective plate 4, further ensuring the safety of the access card. At the same time, because the cross section of the baffle block 9 is an isosceles triangle design, dust can fall downwards through the baffle block 9.

[0054] After the user swipes their card, the protective plate 4 is released. At this time, the spring 7 releases its stored elastic potential energy, pushing the limit rod 6 and the transmission block 5 to reset, thereby causing the protective plate 4 to slide back to its initial position, re-protecting the card reader panel 2 and extending the service life of the card reader panel 2.
