Description

Technical Field

[0001] This utility model relates to the field of traffic facility technology, and more specifically, to a flexible column that can automatically rebound. Background Technology

[0002] Traffic facilities refer to various structures, equipment, and signs and markings installed in traffic locations such as roads, railways, ports, and airports to ensure traffic safety, maintain traffic order, improve traffic efficiency, provide information services, or assist the operation of vehicles and pedestrians. These include guardrails, traffic lights, signs, markings, barriers, bollards, electronic monitoring systems, lighting, toll stations, bus stops, etc.

[0003] A search revealed an existing patent (publication number: CN217325128U) that discloses a resilient anti-collision warning post, comprising: a tension spring (1), a connecting rod (2), and a post cavity (7). The bottom of the tension spring (1) is fixed to the foundation ground; the bottom end of the connecting rod (2) is fixed to the top of the tension spring (1), and the top end is limited to the top of the post cavity (7) by a mounting plate (4); the upper and lower parts of the connecting rod (2) and the tension spring (1) are installed inside the post cavity (7), and the connecting rod (2) and the tension spring (1) together determine the usable height of the resilient anti-collision warning post. The post cavity (7) serves as the external structure of the connecting rod (2) and the tension spring (1); the material of the post cavity (7) has a certain toughness, and due to the cavity structure, it has a certain stiffness in the height direction to bear force, and is malleable in the radial direction. The resilient anti-collision warning post provided by this utility model improves the existing warning post structure, overcomes the shortcomings of the prior art, protects the safety of vehicles and passengers, has a long service life, and requires less unnecessary manual maintenance.

[0004] However, the above-mentioned device also revealed obvious defects in actual use: as the only rebound element, the tension spring 1 has a long rebound stroke and low damping. After the impact, it needs to undergo 3 to 5 low-frequency swings to fully reset, and the reset time is as long as 2 to 3 seconds. In the case of heavy traffic, the slow swing not only hinders the passage of subsequent vehicles, but also easily causes secondary collisions. At the same time, after repeated bending, the tension spring 1 produces residual deformation and its stiffness gradually decreases, causing the return angle of the column cavity 7 to shift, which requires manual adjustment. In addition, the lack of an energy dissipation structure means that almost all the impact energy is absorbed by the tension spring 1, which is prone to "overshoot". The instantaneous displacement of the top of the column can reach 120% of the initial position, which further prolongs the stabilization time. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a flexible column that can automatically rebound, so as to solve the problems of slow reset, easy overshoot, and large residual deformation caused by the device relying on only a single tension spring for rebound.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flexible column with automatic rebound capability, comprising: a base plate; a buffer absorption base assembly mounted on the base plate, the buffer absorption base assembly being used for support and auxiliary buffering; a stop rod assembly mounted on the buffer absorption base assembly, the stop rod assembly being used for blocking and support; and an automatic rebound assembly mounted inside the stop rod assembly, the automatic rebound assembly being used for auxiliary rebound.

[0007] Preferably, the buffer absorption base assembly includes: a buffer absorption plate fixedly installed on the top of the base plate, an installation base fixedly installed on the top of the buffer absorption plate, a bolt threaded onto the installation base, and the installation base fixedly installed on the buffer absorption plate by the bolt.

[0008] Preferably, there are four sets of bolts, and the four sets of bolts are equidistantly arranged on the mounting base.

[0009] Preferably, the stop assembly includes: a connecting plate fixedly installed on the top of the mounting base, a second bolt threadedly connected to the connecting plate, the connecting plate being fixedly installed on the mounting base by the second bolt, a housing being fixedly installed on the top of the connecting plate, and the bottom of the housing being fixedly connected to the mounting base.

[0010] Preferably, the automatic rebound assembly includes: a spring fixedly installed on the top of the second bolt, a rebound steel wire fixedly installed on the top of the spring, an installation sleeve fixedly installed on the top of the inner surface of the housing, one end of the rebound steel wire fixedly installed inside the installation sleeve, and a rubber ring movably sleeved on the outer surface of the rebound steel wire.

[0011] Preferably, the rubber bands are provided in two sets, and the two sets of rubber bands are equidistantly arranged inside the outer shell, and the two sets of rubber bands are fixedly installed inside the outer shell.

[0012] Preferably, the space between the mounting sleeve and the spring wire is filled with anchoring adhesive, and the spring wire is installed inside the mounting sleeve by means of the anchoring adhesive.

[0013] Preferably, the buffer absorption plate is fixedly mounted on the base plate by bolts.

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

[0015] This invention addresses the issue of energy loss when a vehicle accidentally collides with a pillar. The impact force is first transmitted through the outer shell to the connecting plate, where a buffer plate between the mounting base and the bottom plate reduces the initial energy. Subsequently, the compression spring and the rebound wire bend synchronously, while two sets of rubber rings provide radial damping, absorbing the remaining energy in stages and preventing overshoot. The adhesive within the mounting sleeve cures into an elastic pad, locking the rebound wire and providing additional flexibility, allowing the pillar to rebound and immediately return to its original position within a short time, eliminating multiple low-frequency oscillations over several seconds. The rubber rings and springs share the load, significantly reducing metal fatigue and preventing gradual deviation of the rebound angle. The entire energy dissipation-rebound system instantly controls the top displacement to its initial position, ensuring the pillar immediately returns to upright after the vehicle leaves, preventing secondary collisions and achieving truly maintenance-free, long-term stable use.

[0029] Based on Embodiment 1, a preferred embodiment of the automatically resilient flexible column provided by this utility model is, for example... Figures 1 to 4 As shown: The automatic rebound assembly 4 includes: a spring 401 fixedly installed on the top of the bolt 302, a rebound steel wire 402 fixedly installed on the top of the spring 401, an installation sleeve 403 fixedly installed on the top of the inner surface of the housing 303, one end of the rebound steel wire 402 fixedly installed inside the installation sleeve 403, and a rubber ring 404 movably sleeved on the outer surface of the rebound steel wire 402.
