Description

Technical Field

[0001] This utility model relates to the field of access control gate technology, specifically an access control gate with a wear-resistant guide rail structure. Background Technology

[0002] In public places such as subway stations, office buildings, shopping malls and other areas with high population flow, access control gates are key equipment for controlling the entry and exit of people. Their operational stability and service life directly affect the passage efficiency and management security. As the core component of access control gates, the guide structure undertakes the guiding role of the reciprocating movement of the movable gate, and its wear resistance and reliability are particularly important.

[0003] Most existing access control turnstiles use a sliding guide method where the sliding door directly slides into the guide rail. The bottom of the sliding door and the guide components are constantly in a state of sliding friction, which easily leads to severe wear due to frequent opening and closing. This can cause problems such as door misalignment, jamming, or even sinking during operation, affecting not only smooth passage but also potential safety hazards due to structural deformation. Furthermore, in traditional guide structures, the sliding door and guide components are often integrated or fixedly connected. Once the guide parts wear out beyond the acceptable range, the entire sliding door or guide assembly needs to be replaced, resulting in high maintenance costs, complex replacement processes, and prolonged equipment downtime, disrupting normal operation. In addition, while some turnstiles use a rolling guide structure, the fit between the rollers and the guide rail is not precise enough, leading to uneven wear after long-term use. This makes it difficult to balance guide stability and wear resistance, failing to meet the demands of high-frequency, long-term use. Therefore, improving the wear resistance, optimizing maintenance convenience, and enhancing operational stability of access control turnstile guide structures have become urgent technical problems to be solved in the industry.

[0013] (III) Beneficial Effects

[0014] This utility model provides an access control gate with a wear-resistant guide rail structure, which has the following advantages:

[0015] This access control gate with a wear-resistant guide rail structure uses a replacement plate that slides between the guide block and the lower part of the movable door. The guide block provides stable guidance and reduces deviation during the movement of the movable door. The replacement plate is bolted and can be disassembled and replaced individually after wear, without replacing the entire movable door, thus reducing maintenance costs and replacement difficulty.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a wear-resistant guide rail structure access control gate, including a protective shell 1, a positioning plate 2 connected to the inner bottom wall of the protective shell 1 by bolts, a guide block 3 fixedly connected to the top of the positioning plate 2, a movable door 11 slidably connected to the inner side wall of the protective shell 1, a plurality of rollers 14 connected to the upper surface of the outer surface of the movable door 11 by a rotating shaft, and a guide rail 15 fixedly installed on the upper surface of the inner side wall of the protective shell 1.

[0024] In this embodiment, the protective shell 1 serves as the external frame of the entire access control gate, supporting and protecting the internal components. It isolates the internal components such as the guide block 3, the movable door 11, and the guide rail 15 from the external environment, reducing the erosion of the internal structure by dust and impurities. It also prevents personnel from directly contacting the internal moving parts, improving the safety of the equipment and providing a stable installation foundation for the entire device. The positioning plate 2 is bolted to the inner bottom wall of the protective shell 1 and is mainly used to fix the guide block 3. Its stable installation method ensures that the guide block 3 will not be displaced during the sliding of the movable door 11, ensuring the accuracy of the position of the guide block 3. This provides a stable guiding reference for the movement of the movable door 11 and indirectly improves the smoothness of the movement of the movable door 11. The guide block 3 is fixed on the top of the positioning plate 2 and slides in cooperation with the replacement plate 13 below the movable door 11. It provides precise guidance for the reciprocating motion of the movable door 11, effectively reducing the deviation phenomenon during the movement of the movable door 11, ensuring that the movable door 11 runs along the predetermined trajectory, and improving the operational stability of the access control gate. The movable door 11 is a key component of the access control gate for controlling personnel entry and exit. It is opened and closed by sliding. The transparent plate 12 on its outer surface facilitates observation of the situation inside and outside the gate, increasing the safety and convenience of passage. The replacement plate 13 connected below undertakes the function of sliding cooperation with the guide block 3, and can also be replaced separately after wear, reducing maintenance costs. The roller 14 is connected to the upper surface of the movable door 11 through a rotating shaft. The guide rail 15, which works in conjunction with the inner wall of the protective shell 1, uses rolling friction instead of traditional sliding friction, greatly reducing the resistance of the moving door 11 during movement and reducing the wear between components. It also helps to prevent the moving door 11 from sinking significantly during long-term movement, thus extending the service life of the components. The guide rail 15 is fixedly installed on the upper part of the inner wall of the protective shell 1 and works in conjunction with the roller 14 above the moving door 11 to provide a rolling track for the roller 14, ensuring the accuracy of the roller 14's movement trajectory. This, in turn, helps the moving door 11 maintain stable movement. Together with the guide block 3, it improves the smoothness and reliability of the moving door 11's movement.

[0025] In the above embodiment, as a preferred solution, a partition 4 is fixedly connected to the end of the protective shell 1. A hydraulic rod 5 is fixedly installed below the outer surface of the partition 4. A protective shell 16 is fixedly installed on the outer surface of the partition 4 outside the hydraulic rod 5. The partition 4 is fixed to the end of the protective shell 1, serving as a separator and support. It provides a mounting carrier for components such as the hydraulic rod 5, the first positioning seat 6, and the second positioning seat 7, enabling these components to be installed in an orderly manner and work together, ensuring the stable operation of the drive structure of the movable door 11. The hydraulic rod 5 is installed below the outer surface of the partition 4, and its output end is fixed to the bottom of the first positioning seat 6. As the power source for the movement of the movable door 11, it drives the first positioning seat 6 to slide through extension and retraction, and then transmits power through components such as the connecting rod 8 to realize the opening and closing of the movable door 11. Its power output is stable, ensuring the smoothness of the movement of the movable door 11. The protective shell 16 is fixed on the outer surface of the partition 4 and located outside the hydraulic rod 5, mainly protecting the hydraulic rod 5. It can prevent damage to the hydraulic rod 5 from external collisions, dust and other factors, extend the service life of the hydraulic rod 5, and ensure the stability of its power output.

[0026] In the above embodiment, as a preferred solution, the outer surface of the partition 4 is slidably connected to a first positioning seat 6, and the output end of the hydraulic rod 5 is fixedly installed to the bottom of the first positioning seat 6. The first positioning seat 6 is slidably connected to the outer surface of the partition 4 and fixed to the output end of the hydraulic rod 5. Under the drive of the hydraulic rod 5, it slides to transmit the power of the hydraulic rod 5 to the connecting rod 8. It is an important intermediate component in the power transmission process, and the smoothness of its sliding directly affects the efficiency of power transmission.

[0027] In the above embodiment, as a preferred solution, a second positioning seat 7 is fixedly connected to the outer wall of the partition 4. The outer surfaces of the first positioning seat 6 and the second positioning seat 7 are respectively connected to a connecting rod 8 via a rotating shaft. The second positioning seat 7 is fixedly connected to the outer wall of the partition 4 and connected to the connecting rod 8 via a rotating shaft, serving as a fixed fulcrum for the connecting rod 8 and providing support for its movement. It cooperates with the first positioning seat 6 to enable the connecting rod 8 to move along a predetermined trajectory, thereby driving the movable door 11 to move accurately. The two ends of the connecting rod 8 are respectively connected to the first positioning seat 6, the second positioning seat 7, the third positioning seat 9, and the fourth positioning seat 10 via rotating shafts, playing the role of transmitting power and changing the direction of force. It transmits the movement of the first positioning seat 6 and the second positioning seat 7 to the third positioning seat 9 and the fourth positioning seat 10, thereby driving the movable door 11 to slide. Its structural design can ensure the high efficiency and stability of power transmission.

[0028] In the above embodiment, as a preferred solution, the other end of the connecting rod 8 is connected to a third positioning seat 9 and a fourth positioning seat 10 via a rotating shaft. One side of the third positioning seat 9 is fixedly installed to the outer wall of the movable door 11, and one side of the fourth positioning seat 10 is slidably connected to the outer wall of the movable door 11. By fixing one side of the third positioning seat 9 to the outer wall of the movable door 11 and connecting it to the connecting rod 8 via a rotating shaft, the power transmitted by the connecting rod 8 is directly applied to the movable door 11, causing the movable door 11 to move. Its fixed installation method ensures the directness and stability of power transmission. The fourth positioning seat 10 is slidably connected to the outer wall of the movable door 11 and connected to the connecting rod 8 via a rotating shaft. During the movement of the connecting rod 8, it can adapt to the sliding of the movable door 11 and assist the third positioning seat 9 in driving the movable door 11 to move, making the force on the movable door 11 more balanced and the movement more stable.

[0029] In the above embodiment, as a preferred solution, a transparent plate 12 is fixedly connected to the outer surface of the movable door 11, and a replacement plate 13 is bolted to the bottom of the movable door 11. The bottom of the replacement plate 13 is slidably connected to the top of the guide block 3. The transparent plate 12 is fixedly connected to the outer surface of the movable door 11, and the transparent material facilitates the observation of the inside and outside of the gate by the passers-by and the managers, which increases the security and transparency of the access control gate and also makes the gate more aesthetically pleasing. The replacement plate 13 is bolted to the bottom of the movable door 11, and the bottom is slidably connected to the top of the guide block 3. It directly contacts the guide block 3 and slides relative to it, undertaking the guiding and wear-resistant functions of the movable door 11 during movement. Since the bolted connection is used, when the replacement plate 13 is worn, it can be disassembled and replaced separately without replacing the entire movable door 11, which reduces maintenance costs and replacement difficulty.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0031] In this invention, the working steps of the device are as follows:

[0032] When the gate needs to be opened or closed, the hydraulic rod 5 is activated, and its output end extends and retracts, causing the first positioning seat 6, which is fixed thereto, to slide on the outer surface of the partition 4. When the first positioning seat 6 slides, it drives the connecting rod 8 to move through the rotating shaft. At the same time, the second positioning seat 7 serves as a fixed fulcrum to provide support for the connecting rod 8, so that the connecting rod 8 transmits power to the third positioning seat 9 and the fourth positioning seat 10 according to a predetermined trajectory. The third positioning seat 9 directly transmits power to the movable gate 11, and the fourth positioning seat 10 slides on the outer wall of the movable gate 11 to adapt to the movement. The two work together to drive the movable gate 11 to slide, thereby realizing the opening or closing of the gate.

[0033] During the movement of the movable door 11, the replacement plate 13 below slides in conjunction with the guide block 3 on the positioning plate 2. The guide block 3 provides stable guidance for the movable door 11 and reduces deviation. The roller 14 above rolls on the guide rail 15, reducing resistance and wear through rolling friction, while preventing the movable door 11 from sinking.

[0034] If the replacement plate 13 wears out due to long-term sliding, the replacement plate 13 can be replaced separately by removing the bolts, without replacing the entire movable door 11, thus ensuring the continuous and stable operation of the equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
