Description

Technical Field

[0001] This utility model relates to the field of traffic management technology, and more specifically, it relates to a double-bar barrier. Background Technology

[0002] In modern traffic management systems, especially in places such as large parking lots and highway toll booths, higher requirements are placed on the management of barrier gates. With the increase in traffic flow, the maintenance and management of barrier gate equipment has gradually become more complicated, especially when it is necessary to regularly inspect, replace the gate arm or carry out other maintenance.

[0003] Traditional barrier gate designs often require disassembly of the entire device or complex debugging operations. Because existing barrier gate designs often do not allow for easy disassembly of the gate arm, this can lead to excessively long maintenance and replacement times, and may even affect the normal operation of the entire passage system.

[0004] In the event of accidental damage or the need for temporary shutdown of the barrier gate, the disassembly and installation process of traditional barrier gates usually takes a long time. Since the barrier gate arm often adopts a fixed structure, the disassembly process may involve the removal of a large number of bolts and fasteners. These operations require highly skilled technicians and certain tools and equipment. This inconvenient disassembly method not only increases maintenance costs but may also affect traffic efficiency.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a double-bar barrier gate, which has the following beneficial effects:

[0018] 1. The quick-installation mechanism achieves a stable connection between the gate arm and the drive end by setting up a plug-in rod and connecting hole for interlocking, and combining multiple sets of interlocking relationships between the positioning groove and the force-bearing bar. At the same time, through the linkage device of the snap-fit ​​rod and the plug hole, in conjunction with the slide rod, connecting frame, slide groove and pressure plate structure, the gate arm can be quickly installed and fixed without the need for complicated tools, which effectively improves the installation efficiency, simplifies the operation process, and is suitable for scenarios with frequent disassembly or maintenance.

[0019] 2. The limiting mechanism achieves stable positioning of the connecting components in the installation state by setting multiple sets of plug-in relationships between the connecting rod and the limiting groove, and combining the linkage between the rotating sleeve and the limiting block. This prevents the gate arm from being accidentally loosened due to vibration or external force, thus improving the operational safety and reliability of the overall structure. The linkage between the connecting sleeve and the connecting frame ensures that all components of the system are tightly coordinated in the locked state, further enhancing the stability and durability after installation.

[0020] 3. The unlocking mechanism utilizes the sliding engagement of the arc-shaped slider within the annular groove, along with the linkage control between the connecting ring and the push spring, to allow the limiting structure to be quickly released when disassembly is required. Through the rotation of the squeezing block and compression spring in conjunction with the rotating sleeve, the entire limiting structure can be quickly released within a limited space, thereby simplifying the disassembly process and allowing the gate arm to be easily detached from the drive end, meeting the needs of efficient disassembly and maintenance, while also enhancing the system's intelligent and user-friendly operating experience.

[0031] The outer wall of the insertion rod 6 is provided with a positioning groove 15, and the inner wall of the fixing sleeve 8 is provided with a positioning strip 16. Multiple sets of positioning grooves 15 are provided and are slidably connected. The positioning grooves 15 and the positioning strips 16 achieve precise positioning and guidance between the insertion rod 6 and the fixing sleeve 8 through the sliding connection, thereby improving assembly stability and smooth operation.

[0032] A force-bearing strip 17 is fixedly provided on the inner wall of the connecting hole 7. Multiple sets of force-bearing strips 17 are provided and each is adapted to multiple sets of positioning grooves 15. By adapting to the positioning grooves 15, the force-bearing strips 17 share the force of the insertion rod 6, thereby enhancing the overall load-bearing capacity of the connecting hole 7 and improving its resistance to external deformation.

[0033] Each of the multiple sets of snap-fit ​​rods 9 has a guide groove 18, and a guide block 19 is fixedly provided at the top of the fixing sleeve 8. There are multiple sets of guide blocks 19, which are slidably connected.

[0034] A reset spring 20 is provided between the bottom surface of multiple guide blocks 19 and the inner wall of the guide groove 18. The reset spring 20 provides an elastic return force between the guide block 19 and the guide groove 18, so that the structure can automatically reset during use and maintain the good condition of the component.

[0035] The limiting mechanism includes a connecting sleeve 21, a connecting rod 22, a limiting block 23, a rotating sleeve 24, a limiting groove 25, and an unlocking mechanism. The connecting sleeve 21 is fixed to the outside of the connecting frame 12. Multiple sets of connecting rods 22 are fixed to the bottom surface of the connecting sleeve 21. The limiting block 23 is fixed to the bottom end of multiple sets of connecting rods 22. The rotating sleeve 24 rotates on the outer wall of the fixed sleeve 8. Multiple sets of limiting grooves 25 are distributed on the top surface of the rotating sleeve 24 and are slidably connected to multiple sets of connecting rods 22. The sliding cooperation between the connecting rods 22 and the limiting grooves 25 achieves multi-point limiting function through the rotating sleeve 24. The limiting block 23 plays a limiting and stopping role, ensuring the stable locking of the structure in different states.

[0036] The unlocking mechanism includes an unlocking groove 26, an annular groove 27, an arc-shaped slider 28, a connecting ring 29, and a push spring 30. The unlocking groove 26 is located at one end of multiple sets of limiting grooves 25. The arc-shaped groove is located on the top surface of the rotating sleeve 24. Multiple sets of arc-shaped sliders 28 slide within the annular groove 27. The connecting ring 29 is fixed to the top surface of the multiple sets of arc-shaped sliders 28 and located on the outside of the connecting rod 22. Multiple sets of push springs 30 are provided, with both ends fixedly connected to the bottom surface of the connecting sleeve 21 and the multiple sets of connecting rings 29, respectively. The unlocking mechanism uses the push spring 30 to push the arc-shaped slider 28 to move along the annular groove 27, thereby releasing the connecting rod 22 from the limiting groove 25 and facilitating a quick unlocking operation.

[0037] A pressing block 31 is fixedly mounted on the bottom surface of the rotating sleeve 24. Multiple sets of pressing blocks 31 are provided, each with an arc-shaped rod 32 fixedly mounted on its outer wall. Compression springs 33 are mounted on the outer sides of each set of arc-shaped rods 32, with one end of each compression spring fixedly connected to the outer wall of the pressing block 31. A side plate 34 is fixedly mounted on the outer wall of the fixed sleeve 8. Multiple sets of side plates 34 are provided, each with a sliding hole 35 on its outer wall. The sliding holes 35 are slidably connected to the arc-shaped rods 32. The pressing block 31 drives the arc-shaped rods 32 to slide within the sliding holes 35, and the compression springs 33 provide a restoring force, giving the structure good impact resistance and dynamic response capability.

[0038] In this embodiment, when the gate arm 4 needs to be installed, the connecting hole 7 is inserted into the insert rod 6, the multiple sets of force-bearing strips 17 are inserted into the positioning groove 15, and then the fixing sleeve 8 is inserted into the top of the insert rod 6 and pressed against the outer wall of the gate arm 4. The connecting sleeve 21 is pushed to drive the connecting frame 12 to slide along the slide groove 13. The connecting frame 12 drives the pressure plate 14 through the slide rod 11 to push the multiple sets of snap-fit ​​rods 9 to slide along the guide block 19 through the guide groove 18 so that the snap-fit ​​rods 9 are inserted into the insert hole 10. At this time, the connecting sleeve 21 pushes the connecting rod 22 to be inserted into the unlocking hole. The multiple sets of compression springs 33 push the squeezing block 31 to drive the rotating sleeve 24 to rotate, so that the multiple sets of connecting rods 22 slide in the limiting groove 25. The multiple sets of limiting blocks 23 abut against the inner wall of the rotating sleeve 24 to limit the connecting sleeve 21, thus completing the installation of the gate arm 4.

[0039] More specifically, when disassembly is required, rotating the rotating sleeve 24 compresses the compression spring 33 through the squeezing block 31, while causing multiple sets of connecting rods 22 to slide along the limiting groove 25 into the unlocking groove 26, releasing the restraining block 23 from abutting the inner wall of the rotating sleeve 24. At the same time, multiple sets of arc-shaped sliders 28 slide along the annular groove 27, and multiple sets of push springs 30 push the connecting sleeve 21 to drive the connecting frame 12 to slide, while driving the slide rod 11 to push the pressure plate 14 to release the abutment of multiple sets of locking rods 9. Multiple sets of reset springs 20 pull the locking rods 9 out of the insertion hole 10 to release the locking between the fixing sleeve 8 and the insertion rod 6. Then, the fixing sleeve 8 releases the abutment of the gate arm 4, and the gate arm 4 can be disassembled.

[0040] In summary, when the entire equipment is in use or operation: when the gate arm 4 needs to be installed, the connecting hole 7 is inserted into the insertion rod 6, the multiple sets of force-bearing strips 17 are inserted into the positioning groove 15, and then the fixing sleeve 8 is inserted into the top of the insertion rod 6 and pressed against the outer wall of the gate arm 4. The connecting sleeve 21 is pushed to drive the connecting frame 12 to slide along the slide groove 13. The connecting frame 12 drives the pressure plate 14 through the slide rod 11 to push the multiple sets of snap-fit ​​rods 9 to slide along the guide block 19 through the guide groove 18 so that the snap-fit ​​rods 9 are inserted into the insertion hole 10. At this time, the connecting sleeve 21 pushes the connecting rod 22 to be inserted into the unlocking hole. The multiple sets of compression springs 33 push the squeezing block 31 to drive the rotating sleeve 24 to rotate, so that the multiple sets of connecting rods 22 slide in the limiting groove 25. The multiple sets of limiting blocks 23 abut against the inner wall of the rotating sleeve 24 to limit the connecting sleeve 21, thus completing the installation of the gate arm 4.

[0041] When disassembly is required, rotating the rotating sleeve 24 compresses the compression spring 33 through the squeezing block 31, while causing multiple sets of connecting rods 22 to slide along the limiting groove 25 into the unlocking groove 26, releasing the restraining block 23 from abutting the inner wall of the rotating sleeve 24. At the same time, multiple sets of arc-shaped sliders 28 slide along the annular groove 27, and multiple sets of push springs 30 push the connecting sleeve 21 to drive the connecting frame 12 to slide. Simultaneously, the sliding rod 11 pushes the pressure plate 14 to release the abutment of multiple sets of locking rods 9. Multiple sets of reset springs 20 pull the locking rods 9 out of the insertion hole 10 to release the locking between the fixing sleeve 8 and the insertion rod 6. Then, the fixing sleeve 8 releases the abutment of the gate arm 4, and the gate arm 4 can be disassembled.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
