Description

Technical Field

[0001] This utility model relates to a railing, and more particularly to a railing that can be tilted and reset. Background Technology

[0002] Handrails play a vital role in urban infrastructure, widely used in highways, bridges, and public places, primarily providing safety and guiding pedestrians. However, some handrails in certain road sections or scenic areas currently exhibit significant drawbacks, affecting their effectiveness and adaptability. Specifically, traditional handrails often employ fixed structures. While providing stable protection in daily use, in emergencies such as natural disasters like floods, fixed handrails can easily become obstacles, unable to flexibly adapt to environmental changes. For instance, fixed handrails may also be damaged by external forces under extreme weather conditions (such as strong winds and floods). Floodwaters carrying large amounts of debris are blocked by the handrails, increasing the stress surface area and potentially causing them to collapse, thus increasing maintenance costs and safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a railing that can be tilted and reset, so that it can be tilted to avoid damage in the event of sudden natural disasters such as strong winds, heavy rains and floods, thereby reducing maintenance costs and safety risks.

[0004] This utility model is achieved through the following technical solution: a railing that can be tilted and reset, which includes multiple handrail units arranged sequentially in the front-back direction. Each handrail unit includes a horizontal bar and a vertical post. The top of the vertical post is hinged to the horizontal bar, and the adjacent horizontal bars abut against each other.

[0005] It also includes a connecting base plate located at the bottom and extending in the front-to-back direction. Multiple fixed hinge pillars are provided on the connecting base plate in the front-to-back extension direction, and the bottom of the pillars are sequentially hinged to the corresponding fixed hinge pillars.

[0006] A torsion spring is also connected at the hinge joint between the column and the fixed hinge support. One end of the torsion spring is connected to the fixed hinge support, and the other end of the torsion spring is connected to the column.

[0007] It also includes two fixing plates, one of which is installed on the front side of the foremost crossbar and abuts against the crossbar; the other fixing plate is installed on the rear side of the last crossbar and abuts against the crossbar, to prevent the handrail unit from tipping over during daily use.

[0008] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0009] This invention can prevent damage to the plant by proactively tilting it before natural disasters such as typhoons and floods occur. After tilting, it can be easily restored to its original position using a torsion spring, without affecting subsequent normal use. This reduces maintenance costs, improves safety, and extends service life. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0016] like Figures 1 to 4 As shown, a railing that can be tilted and reset includes multiple handrail units 1 arranged sequentially in the front-back direction. Each handrail unit 1 includes a horizontal bar 11 and a post 12. The top of the post 12 is hinged to the horizontal bar 11, and adjacent horizontal bars 11 abut against each other.

[0017] It also includes a connecting base plate 13 located at the bottom and extending in the front-to-back direction. Multiple fixed hinge pillars 2 are provided on the connecting base plate 13 in the front-to-back extension direction. The bottom of the pillar 12 is sequentially hinged to the corresponding fixed hinge pillar 2.

[0018] A torsion spring 23 is also connected at the hinge joint between the column 12 and the fixed hinge support 2. One end of the torsion spring 23 is connected to the fixed hinge support 2, and the other end of the torsion spring 23 is connected to the column 12.

[0019] It also includes two fixing plates 3, one of which is installed on the front side of the foremost crossbar 11 and abuts against the crossbar 11; the other fixing plate 3 is installed on the rear side of the last crossbar 11 and abuts against the crossbar 11, to prevent the handrail unit 1 from falling over during daily use.

[0020] This invention can prevent damage to plants from natural disasters such as typhoons and floods by proactively allowing them to fall in advance. After falling, the plants can be restored to their original positions without affecting normal use. This reduces maintenance costs, improves safety, and extends service life.

[0021] The function of the fixing plate 3 is to prevent the handrail unit 1 from collapsing during use. When it is necessary to make the handrail unit 1 collapse, the fixing plate 3 must be removed to allow the handrail unit to collapse completely. When it is necessary to reset, since the handrail needs to be cleaned and scenic areas generally do not reopen immediately after floods, the foremost fixing plate 3 can be manually secured first. Then, the handrail can be lifted and cleaned sequentially from back to front, and finally the last fixing plate 3 can be secured, thus achieving a stable handrail structure. It is important to emphasize the structure of the torsion spring 23. Figure 2 As can be seen, one end of the torsion spring 23 is fixedly connected to the fixed hinge support 2, and the other end of the torsion spring 23 is fixedly connected to the column 12. This structure helps the handrail unit maintain balance during daily use, and the torsion spring 23 can provide elastic restoring force after the handrail unit 1 collapses, making it easier for the handrail unit 1 to return to its original position. Another function of the torsion spring 23 is to prevent excessive potential energy when the railing collapses, thus reducing the impact force of the railing collapsing.

[0022] Furthermore, a buffer pad 14 is installed on the top surface of the connecting base plate 13. The buffer pad 14 can alleviate the force on the handrail unit 1 and prevent the column 12 or the crossbar 11 from being deformed or damaged due to strong force during the fall.

[0023] Furthermore, the bottom surface of the crossbar 11 is provided with an inner groove 111, and a hinge shaft 112 is fixedly connected to the inner groove 111.

[0024] The top of the column 12 is provided with a hinge hole 121 that is connected to the hinge shaft 112.

[0025] It should be noted that the inner groove 111 is divided by the hinge shaft 112 into a structure where the front groove is larger than the rear groove. This design allows the entire utility model to only fall backward when it is overturned.

[0026] Specifically, before natural disasters such as typhoons and floods occur, the two fixing plates 3 are removed, and then the foremost handrail unit 1 is pushed backward. At this time, all the railings fall down in sequence due to the domino effect. Due to the structural design that the front groove is larger than the rear groove, the column 12 can sink into the front groove when it falls backward, ensuring a complete collapse. This solution can quickly achieve mass collapse of the railings in emergency situations. After the natural disasters such as typhoons and floods have ended, the railings are manually lifted up and cleaned in sequence. At this time, due to the structural design that the front groove is larger than the rear groove, when the applied force is too great and the column 12 has a tendency to tilt forward, the rear groove will restrain the column 12 with the rear side of the column 12, preventing the column 12 from falling forward, and thus preventing the entire device from falling forward. Then the two fixing plates 3 can be restored to their original positions, allowing the entire device to restore the original function of the railing.

[0027] Furthermore, the fixed hinge support includes a left connecting plate 21 and a right connecting plate 22 spaced apart, and the left connecting plate 21 and the right connecting plate 22 are fixedly connected to the connecting base plate 13;

[0028] A hinged column is fixedly connected between the left connecting plate 21 and the right connecting plate 22. The hinged column passes through the column 12 and is rotatably connected to the column 12.

[0029] The torsion spring 23 is sleeved on the outer periphery of the hinged column, with one end of the torsion spring 23 fixedly connected to the left connecting plate 21 or the right connecting plate 22, and the other end of the torsion spring 23 fixedly connected to the column 12. The structure of the fixed hinged column is a conventional technical method. It is important to emphasize the structure of the torsion spring 23 here. Figure 2 As can be seen, one end of the torsion spring 23 is fixedly connected to the left connecting plate 21 or the right connecting plate 22, and the other end of the torsion spring 23 is fixedly connected to the column 12. This structure helps the handrail unit maintain balance during daily use, and the torsion spring 23 can provide elastic restoring force after the handrail unit 1 falls over, making it easier for the handrail unit 1 to return to its original position.

[0030] The usage of this utility model has been described in detail above. It should also be noted that during installation, mounting grooves can be created in the ground so that the installed left connecting plate 21 and right connecting plate 22 are both below the horizontal plane of the mounting grooves. Furthermore, after the handrail unit 1 collapses, the upright 12 sinks into the mounting groove, and the crossbar 11 is either flush with or below the horizontal plane of the mounting groove. Specific design details are as follows: Figure 2 The diagram shows the effect of the ground being formed by the structure to the left of the left connecting plate 21 and to the right of the right connecting plate 22.

[0031] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
