Description

Technical Field

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

[0002] Currently, access control devices are widely used in residential buildings, office buildings, and public places. Their main function is to control personnel access through identity verification, thereby ensuring area security. However, traditional access control devices generally suffer from insufficient protective performance in actual use, mainly in the following aspects:

[0003] On the one hand, access control devices (such as facial recognition cameras and card readers) are usually exposed to the elements. Currently, most access control devices used in smart communities lack adequate protection. While some devices are waterproof, prolonged exposure to sun and rain can still reduce their lifespan. Furthermore, being exposed makes them susceptible to external damage, affecting equipment reliability. Based on this, we propose an access control device with protective features. Utility Model Content

[0004] To address the technical problem of access control readers lacking protection, this utility model provides an access control device with protective functions.

[0005] This utility model is achieved by the following technical solution: an access control device with protective function, including a mounting base plate, an outer telescopic column fixedly connected to the top of the mounting base plate, an inner telescopic column inserted into the inner side of the outer telescopic column, a screw positioning part installed at the connection between the outer telescopic column and the inner telescopic column, the screw positioning part including a screw and a handle, the screw passing through the connection hole between the outer telescopic column and the upper part, and the screw abutting against the outer side wall of the inner telescopic column.

[0006] The outer telescopic column and the inner telescopic column form a telescopic structure. The screw of the screw positioning part passes through the connecting hole of the outer and inner telescopic columns. Rotating the screw can tighten or loosen the outer wall of the inner telescopic column, thereby adjusting the height of the inner telescopic column extending out of the outer telescopic column.

[0007] A positioning frame is installed on the outer side of the screw positioning part; the positioning frame is a U-shaped bracket, and the open end of the positioning frame is welded to the outer side of the outer telescopic column. The screw positioning part passes through the middle through hole of the positioning frame. A connecting plate is fixedly connected to the top of the inner telescopic column, and a deflection shaft is hinged to the top of the connecting plate. The deflection shaft is installed on the support plate. A motion wheel is installed at the bottom of the support plate. The connecting plate and the support plate deflect around the deflection shaft. The motion wheel connected to the bottom of the support plate slides on the mounting base plate, thereby realizing the tilt angle of the support plate at the top of the inner telescopic column, thereby realizing the angle adjustment of the access control reader on the support plate to meet the needs of different application environments. A limit bushing is fixedly installed on the top of the support plate. A sliding rod passes through the inner side of the limit bushing. The two ends of the sliding rod are positioned on the limit bushing. A sliding block is sleeved on the surface of the sliding rod, and a protective plate is fixedly connected to the surface of the sliding block.

[0008] A limiting sleeve is fixed above the support plate, and a sliding rod passes through the limiting sleeve and is fixed at both ends, forming a transverse sliding track. A sliding block is fitted onto the surface of the sliding rod and can slide left and right along the rod. A transparent tempered glass protective plate is fixed to its surface. Two sets of protective plates cover the top of the access control reader and move with the sliding block. The protective plates resist external impacts, scratches, and exposure to sun and rain. When the access control reader needs to be used, the sliding protective plates move away, exposing the recognition area. The support plate and access control reader are tilted to optimize the sliding space of the protective plates and reduce water accumulation.

[0009] As a further optimization of this utility model, the mounting base plate is provided with multiple mounting holes, and expansion bolts are provided in the mounting holes. The expansion bolts are used to fix the mounting base plate to the outside.

[0010] As a further optimization of this utility model, the U-shaped bracket of the positioning frame is fixed to the outside of the outer telescopic column by bolts, and its through hole plays a guiding and supporting role for the rod body of the screw positioning part, ensuring the stability of the adjustment process.

[0011] As a further optimization of this utility model, an access control reader is installed above the support plate; both the support plate and the access control reader are inclined. Two sets of protective plates are provided, covering the access control reader.

[0012] As a further optimization of this utility model, when the access control device is covered by a protective plate, the inclined support plate guides rainwater to the outside, preventing water from seeping into the device and improving its waterproof performance.

[0013] As a further optimization of this utility model, the protective plate is made of transparent tempered glass, which has both high strength and light transmittance, and the surface can resist daily impacts and scratches; at the same time, the protective plate is made of transparent tempered glass, so that the internal situation of the access control device can be observed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the telescopic structure of the outer telescopic column and the inner telescopic column and the locking design of the screw positioning part, allows the extension height of the inner telescopic column to be easily adjusted by rotating the screw, and simultaneously changes the tilt angle of the support plate and the access control reader, so as to meet the recognition needs of users with different height differences in different scenarios such as kindergartens and middle schools, and improve the applicability and ease of operation of the device.

[0016] 2. This utility model features two sets of transparent tempered glass protective panels that are connected to a sliding rod via sliding blocks, allowing them to slide left and right to cover or expose the access control reader. The protective panels combine high strength with light transmittance, effectively resisting external impacts, scratches, and exposure to sun and rain. Combined with an inclined support plate, they guide rainwater outwards, preventing damage to the equipment due to water accumulation and extending its service life. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1:

[0023] Please combine Figures 1-2 This embodiment proposes an access control device with protective function, including a mounting base plate 1. The mounting base plate 1 has multiple mounting holes, and expansion bolts are provided in the mounting holes. The expansion bolts are used to fix the mounting base plate 1 to the outside.

[0024] An outer telescopic column 2 is fixedly connected to the top of the mounting base plate 1. An inner telescopic column 3 is inserted into the inner side of the outer telescopic column 2. A screw positioning part 4 is installed at the connection between the outer telescopic column 2 and the inner telescopic column 3. The screw positioning part 4 includes a screw and a handle. The screw passes through the connecting hole on the outer telescopic column 2 and abuts against the outer side wall of the inner telescopic column 3. A connecting plate 31 is fixedly connected to the top of the inner telescopic column 3. A deflection shaft 32 is hinged to the top of the connecting plate 31. The deflection shaft 32 is installed on the support plate 6. A motion wheel 61 is installed and connected to the bottom of the support plate 6.

[0025] The specific technical solution involves an outer telescopic column 2 and an inner telescopic column 3 forming a telescopic structure. The screw of the screw positioning part 4 passes through the connecting hole of the outer and inner telescopic columns. Rotating the screw can tighten or loosen the outer wall of the inner telescopic column 3. The connecting plate 31 and the support plate 6 deflect around the deflection axis 32. The motion wheel 61 connected to the bottom end of the support plate 6 slides on the mounting base plate 1, thereby adjusting the height of the inner telescopic column 3 extending beyond the outer telescopic column 2. This allows for the tilt angle of the support plate 6 at the top of the inner telescopic column 3, thereby adjusting the angle of the access control reader 11 on the support plate 6 to meet the needs of different application environments, such as kindergartens and middle schools where there are large differences in height.

[0026] A positioning frame 5 is installed on the outer side of the screw positioning part 4. The positioning frame 5 is a U-shaped bracket, with its open end welded to the outer side of the outer telescopic column 2. The screw positioning part 4 passes through the central through hole of the U-shaped bracket. The positioning frame 5 is fixed to the outer side of the outer telescopic column 2 by bolts, and its through hole guides and supports the screw positioning part 4, ensuring stability during the adjustment process.

[0027] A limiting bushing 7 is fixedly installed on the upper part of the support plate 6. A sliding rod 8 passes through the inner side of the limiting bushing 7. Both ends of the sliding rod 8 are positioned on the limiting bushing 7. A sliding block 9 is sleeved on the surface of the sliding rod 8. A protective plate 10 is fixedly connected to the surface of the sliding block 9.

[0028] An access control reader 11 is installed above the support plate 6; both the support plate 6 and the access control reader 11 are inclined. Two sets of protective plates 10 are provided, and the two sets of protective plates 10 cover the access control reader 11.

[0029] More specifically, the limiting sleeve 7 is fixed above the support plate 6, and the sliding rod 8 passes through the limiting sleeve 7 and is fixed at both ends to form a transverse sliding track. The sliding block 9 is sleeved on the surface of the sliding rod 8 and can slide left and right along the rod. The protective plate 10 is a transparent tempered glass plate fixed on its surface. The two sets of protective plates 10 cover the top of the access control reader 11 and move with the sliding block 9. The protective plates 10 resist external impacts, scratches, and sun and rain. When the access control reader 11 needs to be used, the sliding protective plates 10 are moved away to expose the recognition area. The support plate 6 and the access control reader 11 are set at an angle to optimize the sliding space of the protective plates 10 and reduce water accumulation.

[0030] Further explanation is needed: the protective panel 10 is made of transparent tempered glass, combining high strength and light transmittance. Its surface can withstand daily impacts and scratches. To improve the sealing performance when the two sets of protective panels 10 are in contact, sealing gaskets can be installed at the edges of adjacent sides of the two sets of protective panels 10. When the access control reader 11 is covered by the protective panel 10, the inclined support plate 6 guides rainwater to the outside, preventing water from seeping into the device and improving waterproof performance. Simultaneously, the transparent tempered glass of the protective panel 10 allows observation of the internal condition of the access control reader 11.

[0031] I. Overall Structure Installation and Height Adjustment Principles

[0032] Installation and fixing: Fix the device to the wall or bracket by using the mounting holes and expansion bolts on the mounting base plate 1 to ensure the overall structural stability.

[0033] Height Adjustment: The outer telescopic column 2 and the inner telescopic column 3 form a telescopic structure. The screw of the screw positioning part 4 passes through the connecting hole of the outer and inner telescopic columns. Rotating the screw can tighten or loosen the outer wall of the inner telescopic column 3, thereby adjusting the height of the inner telescopic column 3 extending out of the outer telescopic column 2. The connecting plate 31 and the support plate 6 deflect around the deflection axis 32. The motion wheel 61 connected to the bottom end of the support plate 6 slides on the mounting base plate 1, thereby realizing the tilt angle of the support plate 6 at the top of the inner telescopic column 3, thereby realizing the angle adjustment of the access control reader 11 on the support plate 6 to meet the needs of different application environments (such as kindergartens, middle schools and other environments with large height differences); the U-shaped bracket of the positioning frame 5 is fixed to the outside of the outer telescopic column 2 by bolts. Its through hole guides and supports the rod of the screw positioning part 4, ensuring the stability of the adjustment process.

[0034] II. Protective Panel Sliding and Access Control Device Protection Principle

[0035] Sliding assembly operation: The limiting bushing 7 is fixed above the support plate 6, and the sliding rod 8 passes through the limiting bushing 7 and is fixed at both ends to form a transverse sliding track. The sliding block 9 is sleeved on the surface of the sliding rod 8 and can slide left and right along the rod. The protective plate 10 fixed on its surface is a transparent tempered glass plate. Two sets of protective plates cover the top of the access control reader 11 and move with the sliding block 9 to achieve the blocking or exposure of the access control reader 11.

[0036] Protective function: When the access control reader 11 needs protection, the protective plate 10 is pushed to slide on the sliding rod 8 via the sliding block 9, covering the top of the access control reader 11 to resist external impacts, scratches, and sun and rain; when the access control reader 11 needs to be used, the sliding protective plate 10 is moved away to expose the recognition area. The support plate 6 is tilted relative to the access control reader 11, which optimizes the sliding space of the protective plate 10 and reduces water accumulation.

[0037] Material and Protective Design: The protective panel 10 is made of transparent tempered glass, combining high strength and light transmittance, and its surface can withstand daily impacts and scratches. When the access control reader 11 is covered by the protective panel 10, the inclined support plate 6 guides rainwater to the outside, preventing water from seeping into the device and improving waterproof performance. At the same time, the transparent tempered glass of the protective panel 10 allows observation of the inside of the access control reader 11.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
