Description

Technical Field

[0001] This utility model relates to the field of access control gates, and in particular to a retractable access control gate. Background Technology

[0002] Access control gates, also known as vehicle barriers, are entrance and exit management devices specifically designed to restrict the movement of motor vehicles on roads. They are now widely used in highway toll stations and parking lots to manage vehicle entry and exit. Access control gates are an essential component of residential community construction. They can not only effectively control the speed of vehicles entering and exiting the community and improve pedestrian safety, but also effectively control the logistics situation within the community and provide a good anti-theft effect.

[0003] As disclosed in application number CN201920821189.9, a retractable access control barrier gate has a first gate and a second gate fixedly positioned on the ground at intervals. A rotary motor is installed inside the first gate, with its output end fixed to a rotating base. One end of the retractable access control gate is fixed to the rotating base, and a hydraulic press is installed on the rotating base. The output end of the hydraulic press is fixed to the other end of the retractable access control gate. Both the hydraulic press and the rotary motor are electrically connected to a controller. The advantages of this invention are: This invention includes a retractable access control gate, a hydraulic press, a rotating base, a controller, and a rotary motor. The hydraulic press drives the retractable access control gate to extend and retract, thus opening the gate, while the rotary motor drives the retractable access control gate to rise and fall.

[0004] However, when the above-mentioned device is in use, the end of the telescopic gate that is far from the first gate lacks effective support, which causes the telescopic gate to bend and deform after long-term use, making it difficult to extend and retract stably. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a retractable access control gate.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A retractable access control barrier includes: a gate, uprights, a cross telescopic rod assembly, a linear screw drive assembly, a drive slider, a driven slider, a deceleration plate, and a protective plate. Multiple sets of uprights are arranged side-by-side on one side of the gate. The cross telescopic rod assembly is movably disposed between adjacent uprights. The bottom of the upright furthest from the gate is fixedly connected to the drive slider, while the other uprights are fixedly connected to the driven slider. The drive slider and driven slider are slidably disposed on the linear screw drive assembly, which is threadedly connected. Deceleration plates are disposed on both sides of the linear screw drive assembly. The protective plate is disposed above the drive slider and driven slider and is fixedly connected to the deceleration plate.

[0008] Preferably, the cross telescopic rod assembly includes: a first diagonal rod, a second diagonal rod, a sliding hinge rod, and a central hinge shaft. The sliding hinge rod is provided in four sets, and the four sets of sliding hinge rods are rotatably connected to the ends of the first diagonal rod and the second diagonal rod respectively. The sliding hinge rod is slidably disposed in a sliding groove provided on the upright. The middle parts of the first diagonal rod and the second diagonal rod are hinged together by the central hinge shaft.

[0009] Preferably, the sliding hinge rod includes a hinge rod and a sliding limiting block. The hinge rod is rotatably connected to the ends of the first inclined rod and the second inclined rod, and the bottom of the hinge rod is slidably connected to the upright rod through the sliding limiting block.

[0010] Preferably, the pole includes: a pole body and a limiting buckle plate. The limiting buckle plate is provided in two sets. One end of the two sets of limiting buckle plates is fixedly connected to the pole body, and the other end of the two sets of limiting buckle plates is symmetrically arranged in a sliding groove provided on the pole body. The upper end of the limiting buckle plate and the top surface of the sliding groove are provided with an insertion gap.

[0011] Preferably, the linear screw drive assembly includes: a drive motor, a fixed base, a lead screw, a slide bar, and a guide plate. Two sets of fixed bases are provided, with the lead screw rotatably positioned between the two sets of fixed bases. The output end of the drive motor is fixedly connected to one end of the lead screw. The slide bar is fixedly installed between the two sets of fixed bases. Both ends of the guide plate are fixedly connected to the two sets of fixed bases respectively. The slide bar, lead screw, and guide plate are arranged side-by-side. One end of the drive slider is fitted onto the lead screw and connected to it via a thread. The other end of the drive slider is slidably mounted on the slide bar. One end of the driven slider is slidably connected to the slide bar, and the other end of the driven slider is fitted onto the lead screw but not in contact with it. The drive slider and the driven slider are slidably connected to the guide plate.

[0012] Preferably, the drive motor is located at the bottom of the gate and is electrically connected to the controller inside the gate.

[0013] Preferably, the protective platform includes a support plate and an insert, the support plate and the insert are an integral structure, the insert is disposed on the lower side of the support plate, and the insert is embedded in the drive slider or the driven slider.

[0014] The advantages of this utility model are as follows: This utility model forms a telescopic access control system by setting up a vertical pole and a cross telescopic rod assembly. The vertical pole supports the cross telescopic rod assembly, which in turn moves in a telescopic manner. By setting a drive slider, the vertical pole furthest from the gate can be moved. Subsequently, the vertical pole furthest from the gate moves the middle vertical pole through the cross telescopic rod assembly, thus achieving the telescopic effect. By setting a protective platform, a portion of the area above the drive slider and the driven slider can be blocked, thereby improving the stability of vehicle entry. Attached Figure Description

[0028] Example 1, combined with Figure 1 and Figure 2 Explanation:

[0029] A retractable access control barrier includes: a gate 1, uprights 2, a cross telescopic rod assembly 3, a linear screw drive assembly 4, a driving slider 5, a driven slider 6, a deceleration plate 7, and a protective plate 8. Multiple sets of uprights 2 are arranged side-by-side on one side of the gate 1. The cross telescopic rod assembly 3 is movably arranged between adjacent uprights 2. The bottom of the upright 2 furthest from the gate 1 is fixedly connected to the driving slider 5, while the other uprights 2 are fixedly connected to the driven slider 6. The driving slider 5 and the driven slider 6 are slidably mounted on the linear screw drive assembly 4, and the driving slider 5 is threadedly connected to the linear screw drive assembly 4. Deceleration plates 7 are arranged on both sides of the linear screw drive assembly 4. The protective plate 8 is positioned above the driving slider 5 and the driven slider 6 and is fixedly connected to the deceleration plate 7.

[0030] A telescopic access control system is constructed by setting up uprights 2 and a cross-shaped telescopic rod assembly 3. Uprights 2 support the cross-shaped telescopic rod assembly 3, which then performs telescopic movement. A drive slider 5 moves the upright 2 furthest from the gate 1, and subsequently, the middle upright 2 moves via the cross-shaped telescopic rod assembly 3, achieving the telescopic effect. A protective platform 8 shields the area above the drive slider 5 and driven slider 6, improving vehicle entry stability. Due to the modular design of each component, any damaged part can be replaced individually, facilitating maintenance and repair. Multiple uprights 2 are arranged in parallel and connected by a linear screw drive assembly 4, making the overall structure more stable and less prone to deformation under external forces.

[0031] Example 2, based on Example 1, combined with... Figure 3 and Figure 4 Explanation:

[0032] The cross telescopic rod assembly 3 includes: a first diagonal rod 31, a second diagonal rod 32, a sliding hinge rod 33, and a central hinge shaft 34. The sliding hinge rod 33 is provided in four sets, and the four sets of sliding hinge rods 33 are rotatably connected to the ends of the first diagonal rod 31 and the second diagonal rod 32 respectively. The sliding hinge rods 33 are slidably disposed in the sliding grooves provided on the upright 2. The middle parts of the first diagonal rod 31 and the second diagonal rod 32 are hinged together by the central hinge shaft 34.

[0033] The sliding hinge rod 33 includes a hinge rod 331 and a sliding limiting block 332. The hinge rod 331 is rotatably connected to the ends of the first inclined rod 31 and the second inclined rod 32. The bottom of the hinge rod 331 is slidably connected to the upright rod 2 through the sliding limiting block 332.

[0034] The sliding hinge rod 33 slides within a groove on the upright 2, and the first diagonal rod 31 and the second diagonal rod 32 are hinged together via the central hinge shaft 34, allowing the entire assembly to flexibly extend and retract to adapt to passages of varying widths. The four sets of sliding hinge rods 33 are evenly distributed at the ends of the first diagonal rod 31 and the second diagonal rod 32, resulting in more uniform force distribution during extension and retraction, reducing localized stress concentration, and improving structural stability and durability. The cross-shaped telescopic rod assembly has a relatively simple design, facilitating production and installation while reducing maintenance complexity. The hinged connection of the central hinge shaft 34 allows the rods to swing within a certain angle range, which helps absorb and disperse impacts from uneven ground or external forces during access control gate operation, enhancing the overall structural stability.

[0035] Example 3, based on Example 2, combined with Figure 5 Explanation:

[0036] The upright 2 includes an upright body 21 and a limiting buckle plate 22. The limiting buckle plate 22 is provided in two sets. One end of the two sets of limiting buckle plates 22 is fixedly connected to the upright body 21, and the other end of the two sets of limiting buckle plates 22 is symmetrically arranged in the sliding groove provided on the upright body 21. The upper end of the limiting buckle plate 22 and the top surface of the sliding groove are provided with an insertion gap.

[0037] The limiting plates 22 are symmetrically arranged within the slide groove, providing guidance for the sliding hinge rod 33 and ensuring the stability of the telescopic rod assembly during sliding. The presence of the limiting plates 22 prevents the sliding hinge rod 33 from accidentally detaching under external force, improving the overall structural reliability. A gap is provided between the upper end of the limiting plates 22 and the top surface of the slide groove, allowing the sliding hinge rod 33 to be inserted into the slide groove through the gap, facilitating installation.

[0038] Example 4, based on Example 3, combined with Figure 6 Explanation:

[0039] The linear screw drive assembly 4 includes: a drive motor 41, a fixed base 42, a lead screw 43, a slide rod 44, and a guide plate 45. Two sets of fixed bases 42 are provided. The lead screw 43 is rotatably disposed between the two sets of fixed bases 42. The output end of the drive motor 41 is fixedly connected to one end of the lead screw 43. The slide rod 44 is fixedly installed between the two sets of fixed bases 42. Both ends of the guide plate 45 are fixedly connected to the two sets of fixed bases 42 respectively. The slide rod 44, lead screw 43, and guide plate 45 are arranged side-by-side. One end of the drive slider 5 is fitted onto the lead screw 43 and connected to it via a thread. The other end of the drive slider 5 is slidably disposed on the slide rod 44. One end of the driven slider 6 is slidably connected to the slide rod 44, and the other end of the driven slider 6 is fitted onto the lead screw 43 but does not contact the lead screw 43. The drive slider 5 and the driven slider 6 are slidably connected to the guide plate 45.

[0040] The driven slider 6 is driven by the upright 2 to move linearly via the slide rod 44 and the guide plate 45, and the driving slider 5 is driven by the lead screw 43 to rotate linearly, thereby driving the upright 2 furthest from the gate 1 to move.

[0041] The drive motor 41 is located at the bottom of the gate 1 and is electrically connected to the controller inside the gate 1.

[0042] Example 5, based on Example 4, combined with Figure 7 Explanation:

[0043] The protective platform 8 includes a support plate 81 and an insert 82. The support plate 81 and the insert 82 are an integral structure. The insert 82 is disposed on the lower side of the support plate 81 and is embedded in the drive slider 5 or the driven slider 6.

[0044] The insert 82, embedded within the drive slider 5 or driven slider 6, increases the stability of the connection between the protective platform 8 and the slider, reducing swaying and displacement during movement. The integrated support plate 81 and insert 82 provide more comprehensive protection, preventing fingers or other objects from being trapped between the slider and the guide rail during movement, thus improving safety. The insert 82 can be made of a wear-resistant material to reduce wear between it and the slider, extending its service life.

[0045] The working principle of this utility model is as follows: When this device is in use, the drive motor 41 drives the lead screw 43 to rotate, thereby causing the drive slider 5 to move the pole 2 furthest from the gate 1 toward the gate 1. As the pole 2 furthest from the gate 1 moves, the other poles 2 move closer to each other under the cross telescopic rod assembly 3 to complete the function of opening the access control gate. The driven slider 6 plays a guiding role for the other poles 2. This utility model has a reasonable structure and is easy to use. It can effectively support the access control gate and improve the overall stability of the equipment operation.
