Description

Technical Field

[0001] The utility model relates to the technical field of barrier gate rods, in particular to a buffer barrier gate rod. Background Art

[0002] The barrier is an indispensable part of the parking system, helping to manage the orderly entry and exit of vehicles in the parking lot. It is mainly classified into straight-arm barriers, curved-arm barriers, fence barriers, etc. At the same time, the barrier is also called a vehicle blocker, which is widely used in highway toll stations, parking lots, communities, and the gates of enterprises and institutions to manage the entry and exit of vehicles. The electric barrier can be raised and lowered by remote control alone, and can also be automatically managed through the parking management system (i.e. IC card swiping management system).

[0003] After searching, the Chinese patent document application number: 202022561657.9 discloses a buffer assembly for a gate rod, including a gate rod, a column is arranged at one end of the gate rod away from the gate host, the lower end of the column is connected to the ground, an annular groove is provided on the peripheral side of the upper end of the column, a buffer spring is embedded in the annular groove, the upper end of the column is provided with a lifting sleeve that abuts against the upper end of the buffer spring, and a support seat is provided at the upper end of the lifting sleeve, and a bracket is provided on the support seat for the gate rod end to abut. The utility model has the following advantages and effects: when the gate rod falls, relying on the buffering effect of the buffer spring, the force generated when the gate rod falls can be slowly offset, and finally a better buffering effect on the fall of the gate rod can be achieved, thereby reducing the burden on the motor in the gate host, which is conducive to extending the service life of the motor.

[0004] However, the above-mentioned buffer assembly for a barrier rod still has the following defects:

[0005] The buffer assembly only uses the buffering effect of the buffer spring to offset the force generated when the gate rod falls. However, after long-term use, the buffer spring may lose its original elasticity due to fatigue, aging or corrosion, affecting the buffering effect. Therefore, we need a buffer gate rod to solve the above problem. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 and 2 The utility model provides a technical solution: a buffer barrier rod comprises a barrier chassis 1, a barrier rod body 5 is rotatably installed inside the barrier chassis 1, so as to adjust the position of the barrier rod body 5 relative to the barrier chassis 1, a cavity 501 is provided inside the barrier rod body 5, and a plurality of buffer components are arranged inside the cavity 501, the buffer component comprises a support rod 6, a cylinder 13 and a reset spring 16, the top end of the support rod 6 is connected with the inside of the cavity 501 by a rotating component, the bottom end of the support rod 6 is fixedly connected with the top end of the reset spring 16, a connecting block 603 is installed at the bottom end of the reset spring 16, the bottom end of the connecting block 603 is threadedly connected to the inside of the cylinder 13, a U-shaped groove 1302 is provided at the bottom end of the cylinder 13, a fixing pad 15 is installed at the bottom end of the U-shaped groove 1302, and the fixing pad 15 is arranged as a buffer pad, and a fixing component for placing the support rod 6 is arranged at one end of the support rod 6;

[0027] When in use, by designing the buffer component as an independent module including the support rod 6, the cylinder 13, the return spring 16 and the connecting block 603, these wearing parts can be easily replaced or maintained. When the return spring 16 is fatigued, aged or corroded due to long-term use, resulting in degradation of performance, there is no need to replace the barrier rod body 5 as a whole, but only need to replace the affected buffer component separately, which greatly reduces the maintenance cost and difficulty. A fixed pad 15 is arranged in the U-shaped groove 1302 at the bottom end of the cylinder 13 as a buffer pad, which not only provides an additional buffer layer, but also can reduce the impact force directly borne by the return spring 16 to a certain extent, further protect the return spring 16 and extend its service life.

[0028] See also Figure 1 and 4 A moving groove 401 is provided inside the barrier gate chassis 1, and a driving motor 3 is installed on the back of the barrier gate chassis 1. The output shaft of the driving motor 3 is fixedly connected with a threaded rod 301, and drives the threaded rod 301 to rotate. One end of the threaded rod 301 is rotatably installed on one side inner wall of the moving groove 401, and the surface of the threaded rod 301 is threadedly connected to the other end of the barrier gate rod body 5, so that the barrier gate rod body 5 rotates with the rotation of the threaded rod 301. Due to the characteristics of the threaded connection, the barrier gate rod body 5 can maintain a relatively stable state during the lifting process, reducing shaking and jitter, thereby improving the overall stability of the barrier gate system.

[0029] See also Figure 1 and 4 The inner wall of the moving groove 401 is provided with an inclined angle 4, and the upper part of the inclined angle 4 is fitted and connected with the bottom of one end of the barrier rod body 5. The design of the inclined angle 4 enables the barrier rod to slide along a smoother path when it is raised or lowered in the moving groove 401, reducing the direct contact area with the inner wall of the moving groove 401, thereby reducing friction and wear, and extending the service life of the barrier rod body 5 and the moving groove 401.

[0030] See also Figure 1 and 5 The rotating assembly includes a first rotating rod 601, both ends of which are rotatably mounted on the inner walls on both sides of the cavity 501, and the outer wall of the first rotating rod 601 passes through the top side wall of the support rod 6 and is slidably connected to the inside of the support rod 6. The first rotating rod 601 is rotatably mounted on the inner walls on both sides of the cavity 501 and is slidably connected to the support rod 6, so that the support rod 6 can rotate relative to the barrier rod body 5 through the first rotating rod 601, so that these components can be relatively easily disassembled and replaced when necessary.

[0031] See also Figure 5 The surface of the connecting block 603 is provided with an external thread 602, and the inner wall of the cylinder 13 is provided with an internal thread 1301. The external thread 602 is threadedly connected with the internal thread 1301. The threaded connection between the external thread 602 and the internal thread 1301 can form a tight engagement, providing a strong connection strength, ensuring a stable connection between the connecting block 603 and the cylinder 13, and is not easy to loosen or separate due to external force.

[0032] See also Figure 5 A second rotating rod 1401 is rotatably installed on the inner walls of both sides of the U-shaped groove 1302, and a fixed rod 14 is fixedly installed on the surface center of the fixed pad 15. The outer wall of the second rotating rod 1401 passes through the bottom end of the fixed rod 14 and is slidably connected with the fixed rod 14, so that the fixed pad 15 can be rotated relative to the cylinder 13 through the fixed rod 14 and the second rotating rod 1401, so as to adjust the position of the fixed pad 15 relative to the cylinder 13. When subjected to external force, the mutual cooperation between the U-shaped groove 1302, the second rotating rod 1401 and the fixed rod 14 can effectively disperse the stress, avoid structural damage caused by stress concentration, and improve the stability and durability of the entire structure.

[0033] See also Figure 4The fixing assembly includes a fixing seat 9, a spring plunger 10 and a mounting block 11. The bottom end of the fixing seat 9 is flush with the bottom end of the barrier gate chassis 1. The bottom ends of the spring plunger 10 are installed on both sides of the top end of the fixing seat 9. The top end of the spring plunger 10 is connected to the bottom end of the mounting block 11. One end of the barrier gate rod body 5 is placed on the top end of the mounting block 11. The spring plunger 10, as a key component connecting the fixing seat 9 and the mounting block 11, has good buffering and shock absorbing performance. When the barrier gate rod body 5 is impacted by external force or rapidly lifted and lowered, the spring plunger 10 can absorb part of the impact force, reduce damage to the fixing seat 9 and the barrier gate rod, and at the same time improve the stability and service life of the system.

[0034] See also Figure 4 A groove is provided at the top of the mounting block 11, and a buffer plate 12 is placed on the inner surface of the groove. The buffer plate 12 is fitted and connected to the bottom of one end of the barrier rod body 5. When the barrier rod body 5 encounters a sudden stop or is impacted by external force during the lifting process, the buffer plate 12 can absorb part of the impact force, reduce the direct impact on the barrier rod body 5 and the mounting block 11, and help protect the barrier rod body 5 and the mounting block 11 from damage and extend their service life.

[0035] See also Figure 1 and 3 A fixing plate 7 is fixedly installed on one side of the surface of the barrier pole body 5, and a plurality of buffer springs 701 are installed on the surface of the fixing plate 7. One end of the plurality of buffer springs 701 is fixedly connected to an anti-collision plate 8. The arrangement of the plurality of buffer springs 701 can absorb and disperse the impact force through the elastic deformation of the buffer springs 701 when the barrier pole body 5 is impacted, thereby significantly reducing the damage to the barrier pole body 5 and surrounding equipment caused by the impact.

[0036] See also Figure 1 A face recognition screen 2 is installed on the surface of the gate chassis 1, and a control panel is installed inside the face recognition screen 2. The control panel is electrically connected to the drive motor 3 and the face recognition screen 2. Through the linkage between the face recognition screen 2 and the control panel, the system can monitor the use of the channel in real time. Once abnormal behavior or unauthorized personnel attempt to enter, an alarm will be issued immediately to remind security personnel to take corresponding measures.
