Description

Technical Field

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

[0002] Access control devices are the core control equipment of access control systems. Using high-capacity FLASH memory as the storage medium, they offer reliable data storage, ensuring data integrity even in the event of power failure, and integrate management and automatic control. They are widely used in access control, attendance management, security alarms, parking control, elevator control, and building automation in smart buildings or smart communities.

[0003] A current type of optical touch-sensitive metal button access control machine, as described in patent CN210348578U, comprises: a panel, a middle shell, a circuit board, and a mounting plate, which are fixedly connected in sequence. The metal panel and the lower part of the middle shell have corresponding through holes, and a dome button is provided at a corresponding position on the lower part of the circuit board. It also includes an antenna box, a plastic button, an antenna board, and a silicone button, which are sequentially snapped together to form a whole. The whole assembly is fitted into the through holes and fixed to the dome button on the circuit board. The advantages of this invention are: compared to access control machines with non-metallic buttons, the product uses optical touch-sensitive metal buttons, which are less affected by water and oil stains, have fewer limitations on panel material, and have strong anti-electromagnetic interference capabilities. Furthermore, the product uses two main components directly assembled, making maintenance and replacement convenient; the button panel is integrated with the whole machine, resulting in better sealing.

[0004] Regarding the aforementioned technologies, the applicant discovered that in the use of a metal touch-screen access control device, the middle shell is fixed to the metal panel, circuit board, and mounting plate using screws. While screw fixing provides a secure hold, access control devices are often in direct contact with external objects, such as unlocking by entering a password or swiping a magnetic door sensor. This direct-touch unlocking inevitably leads to oil, wear, and water stains on the device's outer surface. Since existing access control devices are disassembled infrequently, oil and water stains can easily accumulate at the screw fixing points, causing rust and making disassembly inconvenient and potentially damaging the device's components. Therefore, we propose a metal touch-screen access control device. Utility Model Content

[0005] The purpose of this invention is to provide a device that facilitates easy disassembly of the outer casing, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal touch access control device, including an access control machine and an access control panel. A telescopic component is installed on one side of the outer wall of the access control panel. The telescopic component includes a housing, and two housings are provided. A stabilizing block is provided between the two housings. A limiting groove for sliding of the stabilizing block is opened on one side of the outer wall of the housing. A telescopic spring is provided between the two housings. A concealed groove for fixing the telescopic spring is opened on the outer side wall of the housing. Mounting grooves for sliding of the housing are opened at both ends of the access control panel.

[0030] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0031] Please see Figures 1-6The diagram illustrates a metal touch-sensitive access control device, including an access control machine 1 and an access control panel 101. A mounting base 102 is fixedly installed on the other side of the outer wall of the access control panel 101. Numeric buttons 103 are installed on the access control panel 101 near the outer casing 201. A doorbell 104 is installed at the bottom of the outer wall of the access control panel 101 near the numeric buttons 103. A display screen 105 is installed at the top of the outer wall of the access control panel 101 near the numeric buttons 103. Unlocking the access control device is achieved through the interaction of the numeric buttons 103, the doorbell 104, and the display screen 105. A telescopic component 2 is installed on one side of the outer wall of the access control panel 101. The telescopic component 2 includes the outer casing 201. The housing 201 has two shells, and a stabilizing block 202 is provided between the two shells 201. A limiting groove 2021 for sliding of the stabilizing block 202 is provided on one side of the outer wall of the shell 201. The two ends of the stabilizing block 202 are T-shaped. The stabilizing block 202 is slidably connected to the limiting groove 2021. A telescopic spring 203 is provided between the two shells 201. A hidden groove 2031 for fixing the telescopic spring 203 is provided on the outer side wall of the shell 201. The two ends of the access control panel 101 have mounting grooves 204 for sliding of the shell 201. The side of the shell 201 near the mounting groove 204 is L-shaped. The bottom of the mounting groove 204 is higher than the bottom of the access control panel 101.

[0032] When installing the telescopic assembly 2, the two outer shells 201 are pulled apart to the sides. Due to the stabilizing block 202 and the limiting groove 2021, the outer shells 201 move horizontally, and the telescopic spring 203 deforms and stretches at the same time. Then, the L-shaped parts on both sides of the outer shell 201 are aligned with the mounting groove 204, and the two outer shells 201 are brought together until the outer shell 201 and the mounting groove 204 are completely fitted. Through the pull-back between the telescopic spring 203 and the hidden groove 2031, and the limiting between the mounting groove 204 and the outer shell 201, the outer shell 201 is installed while the installed outer shell 201 is also limited, ensuring the stability of the telescopic assembly 2 after installation.

[0033] When disassembling the telescopic component 2, the outer casing 201 can be pulled open again to disassemble the outer casing 201. This not only improves the efficiency of installing and disassembling the telescopic component 2, but also avoids the inconvenience of separating the access control machine 1 and the telescopic component 2 when necessary, further improving the practicality of the telescopic component 2 in use.

[0034] Please see Figures 3-6As shown in the figure, a fixing component 3 is installed on the outer shell 201 near the mounting groove 204. The fixing component 3 includes a hemispherical locking block 301, which is fixedly connected to both sides of the L-shaped part of the outer shell 201. There are two sets of hemispherical locking blocks 301, and each set of hemispherical locking blocks 301 is arranged in an array. The inner wall of the mounting groove 204 has slots 302 on both sides for the hemispherical locking blocks 301 to engage. The slots 302 are made of elastic plastic. Anti-slip pads 303 are fixedly installed on the mounting groove 204 near the slots 302. There are two sets of anti-slip pads 303, and each set of anti-slip pads 303 is arranged adjacent to the hemispherical locking blocks 301.

[0035] During the installation of the telescopic assembly 2, as the outer shell 201 moves toward the mounting groove 204, the hemispherical locking block 301 moves toward the locking groove 302. As the outer shell 201 and the mounting groove 204 gradually fit together, the hemispherical locking block 301 undergoes compression deformation. When the outer shell 201 is fully inserted into the mounting groove 204, the hemispherical locking block 301 engages with the locking groove 302. The anti-slip pad 303 further secures the outer shell 201 by abutting against the side wall of the outer shell 201, improving the stability of the telescopic assembly 2 after installation and ensuring the safety of the access control machine 1 during use.
