Technical Field
[0001] This utility model relates to the field of safety railing technology, specifically to a safety railing designed to prevent knocking down. Background Technology
[0002] Currently, the guardrails used in municipal engineering are often simple railings. When they are hit by a car, they will be knocked down, and the guardrails next to them will also be damaged, causing road blockage, resulting in personal injury and economic loss. In this case, there is a need to design a guardrail that will not be easily knocked down when hit by a car, and the impact on adjacent guardrails will not cause traffic accidents.
[0003] In existing technology, the base of the guardrail is pre-embedded in the ground, and the fixing frame of the guardrail is fixed to the base with bolts. After all the fixing frames are installed, the guardrail panels are fixed to the fixing frames to protect the road.
[0004] However, in actual use, when the guardrail is impacted, it is subjected to great pressure, which can cause the guardrail to tilt and thus affect road traffic. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a safety guardrail that prevents tipping over, thus solving the problem that when the guardrail is impacted in actual use, it experiences significant pressure, leading to tipping over and impacting road traffic.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety guardrail for preventing collisions, comprising a mounting plate, a support seat mounted on one side of the outer wall of the mounting plate, and a buffer structure mounted on the other side of the mounting plate. The buffer structure includes: a compression wheel disposed on the outer wall of the mounting plate; a mounting shell disposed on the side of the mounting plate near the compression wheel and rotatably connected to the outer wall of the compression wheel via a damping bearing; a mounting block mounted on the side of the outer wall of the mounting shell away from the compression wheel and fixedly connected to the outer wall of the mounting plate; and a protective device installed between the mounting block and the mounting shell. The compression wheel and the mounting shell, through their cooperation, guide and decelerate the vehicle upon impact, while the protective device between the mounting block and the mounting shell provides a buffering effect.
[0007] Preferably, the protective device includes: a support rod rotatably connected to the outer wall of the mounting housing via a pin; a slider rotatably connected to the end of the support rod away from the mounting housing via a pin, and slidably engaged with the inner wall of the mounting block; a slide rod inserted into the inner wall of the slider and fixedly connected to the inner wall of the mounting block; and a spring sleeved on the outer wall of the slide rod and pressed against the slider and the mounting block; wherein, through the cooperation of the support rod and the slider, the spring moves on the outer wall of the slide rod, so that the support rod protects the mounting plate.
[0008] Preferably, an adjustment device is fixedly connected to the outer wall of the mounting shell. The adjustment device includes: a threaded rod, fixedly connected to the outer wall of the mounting shell and inserted into the inner wall of the mounting plate; and an adjusting nut, threadedly connected to one side of the threaded rod extending to the outer wall of the mounting plate. The position of the mounting shell is adjusted by the cooperation of the threaded rod and the adjusting threaded rod.
[0009] Preferably, a support rod is rotatably connected to the side of the mounting plate away from the extrusion wheel via a pin. An extension rod is installed on the outer wall of the support rod, and an angle device is installed at the bottom of the extension rod. The angle device includes: a rotating rod, fixedly connected to the bottom of the extension rod and rotatably connected to the top of the support base via a damping bearing; a locking block, inserted into the inner wall of the rotating rod and slidably locked into the inner wall of the support base; a return spring, pressed against one end of the locking block and conforming to the inner wall of the support base; and a pull rod, inserted into the inner wall of the return spring, fixedly connected to the end of the locking block away from the rotating rod, passing through the side wall of the support base, and movably connected to the support base. Through the cooperation of the rotating rod and the locking block, the pull rod drives the return spring to move, causing the locking block to move out of the rotating rod, thereby adjusting the angle of the support rod.
[0010] Preferably, the bottom of the mounting plate is fixedly connected to a base by bolts, and the top of the base is fixedly connected to a plug rod, the outer wall of which is inserted into the bottom of the mounting plate.
[0011] Beneficial effects
[0012] This utility model provides a safety barrier to prevent tipping over. It has the following advantages: The safety barrier, through the cooperation of a compression wheel, a mounting shell, and a mounting block, has a compression wheel installed on one side of the mounting plate. When the barrier is impacted, the rotation of the compression wheel reduces the impact force on the vehicle, thus preventing the safety barrier from tipping over and avoiding any impact on road traffic.
[0013] By using the combination of the locking block, the pull rod, and the return spring, when adjusting the angle of the support base and the support rod, pulling the pull rod causes the locking block to separate from the outer wall of the rotating rod, adjusting the angle of the support rod and the support base. After adjustment, releasing the pull rod causes the locking block to be inserted into the rotating rod under the action of the return spring, fixing the rotating rod and allowing the support base to support the mounting plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] In actual use, when the guardrail is impacted, it experiences significant pressure, which can cause it to tip over and disrupt road traffic.
[0022] In view of this, the present invention provides a safety guardrail that prevents knocking down, which solves the problem that when the guardrail is impacted in actual use, it is subjected to great pressure, which causes the guardrail to tilt and thus affects road traffic.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0024] Example 1: By Figure 1-5 It is known that a collision-prevention safety guardrail includes a mounting plate 1, a support base 14 installed on one side of the outer wall of the mounting plate 1, and a buffer structure 2 installed on the other side of the mounting plate 1. The buffer structure 2 includes: a compression wheel 21, disposed on the outer wall of the mounting plate 1; a mounting shell 22, disposed on the side of the mounting plate 1 near the compression wheel 21, and rotatably connected to the outer wall of the compression wheel 21 via a damping bearing; a mounting block 23, installed on the side of the outer wall of the mounting shell 22 away from the compression wheel 21, and fixedly connected to the outer wall of the mounting plate 1; and a protective device 24, installed between the mounting block 23 and the mounting shell 22. The compression wheel 21 and the mounting shell 22 work together to guide and decelerate the vehicle after impact, while the protective device 24 between the mounting block 23 and the mounting shell 22 provides a buffering effect.
[0025] In the specific implementation process, it is worth noting that with the cooperation of the extrusion wheel 21, the mounting shell 22 and the mounting block 23, the extrusion wheel 21 is installed on one side of the mounting plate 1. When the protective plate is hit, the vehicle will be reduced by the rotation of the extrusion wheel 21, so that the safety guardrail will not tilt when it is hit, thus avoiding the impact of the guardrail tilting on road traffic.
[0026] Furthermore, the protective device 24 includes: a support rod 241, rotatably connected to the outer wall of the mounting housing 22 via a pin; a slider 242, rotatably connected to the end of the support rod 241 away from the mounting housing 22 via a pin, and slidably engaged with the inner wall of the mounting block 23; a slide rod 243, inserted into the inner wall of the slider 242, and fixedly connected to the inner wall of the mounting block 23; and a spring 244, sleeved on the outer wall of the slide rod 243, and pressed against the slider 242 and the mounting block 23; wherein, through the cooperation of the support rod 241 and the slider 242, the spring 244 moves on the outer wall of the slide rod 243, so that the support rod 241 protects the mounting plate 1;
[0027] In the specific implementation process, it is worth noting that, with the cooperation of the support rod 241, the slider 242 and the spring 244, when the pressure on the extrusion wheel 21 is too great, the support rod 241 will drive the slider 242 to move on the outer wall of the slider 243 and squeeze the spring 244 to offset the impact force and play a protective role. When normally placed, the position of the extrusion wheel 21 is limited by the action of the spring 244.
[0028] Furthermore, an adjustment device 3 is fixedly connected to the outer wall of the mounting shell 22. The adjustment device 3 includes: a threaded rod 31, which is fixedly connected to the outer wall of the mounting shell 22 and inserted into the inner wall of the mounting plate 1; and an adjustment nut 32, which is threadedly connected to one side of the threaded rod 31 extending to the outer wall of the mounting plate 1. The position of the mounting shell 22 is adjusted by the cooperation of the threaded rod 31 and the adjustment nut 32.
[0029] In the specific implementation process, it is worth noting that, with the cooperation of the adjusting device 3, the mounting shell 22 and the threaded rod 31, the length of the threaded rod 31 can be shortened by rotating the adjusting nut 32, so that the extrusion force on the extrusion wheel 21 can be adjusted.
[0030] Specifically, when using this anti-collision safety barrier, after the barrier is installed, the length of the threaded rod 31 is shortened by rotating the adjusting nut 32, which adjusts the compressive force on the compression wheel 21. The compression wheel 21 is then installed on one side of the mounting plate 1. When the barrier is impacted, the impact force on the vehicle is reduced by the rotation of the compression wheel 21, thus preventing the safety barrier from tipping over and avoiding its impact on road traffic. When the pressure is too high, the support rod 241 will drive the slider 242 to move on the outer wall of the slider 243 and compress the spring 244 to offset the impact force, thus providing protection. When normally placed, the position of the compression wheel 21 is limited by the action of the spring 244.
[0031] Example 2: From Figure 1-5 It is known that a support rod 12 is rotatably connected to the side of the mounting plate 1 away from the extrusion wheel 21 via a pin. An extension rod 13 is installed on the outer wall of the support rod 12, and an angle device 4 is installed at the bottom of the extension rod 13. The angle device 4 includes: a rotating rod 41, which is fixedly connected to the bottom of the extension rod 13 and rotatably connected to the top of the support base 14 via a damping bearing; a locking block 42, which is inserted into the inner wall of the rotating rod 41 and slidably locked into the inner wall of the support base 14; a return spring 43, which abuts against one end of the locking block 42 and fits against the inner wall of the support base 14; and a pull rod 44, which is inserted into the inner wall of the return spring 43, fixedly connected to the end of the locking block 42 away from the rotating rod 41, and passes through the side wall of the support base 14 and is movably connected to the support base 14. Through the cooperation of the rotating rod 41 and the locking block 42, the pull rod 44 drives the return spring 43 to move, causing the locking block 42 to move out of the rotating rod 41, thereby adjusting the angle of the support rod 12.
[0032] In the specific implementation process, it is worth noting that, with the cooperation of the locking block 42, the pull rod 44 and the return spring 43, when adjusting the angle of the support base 14 and the support rod 12, the pull rod 44 is pulled, which causes the locking block 42 to separate from the outer wall of the rotating rod 41, adjusting the angle of the support rod 12 and the support base 14. After the adjustment is completed, the pull rod 44 is released, and the locking block 42, under the action of the return spring 43, is inserted into the rotating rod 41 to fix the rotating rod 41, so that the support base 14 supports the mounting plate 1.
[0033] Furthermore, a base 11 is fixedly connected to the bottom of the mounting plate 1 by bolts, and a plug rod 15 is fixedly connected to the top of the base 11. The outer wall of the plug rod 15 is inserted into the bottom of the mounting plate 1.
[0034] In the specific implementation process, it is worth noting that, with the cooperation of the base 11 and the plug rod 15, when installing the mounting plate 1, it is inserted into the top of the plug rod 15 to make the mounting plate 1 more stable during installation.
[0035] Specifically, based on the above embodiments, when installing the guardrail, the mounting plate 1 is inserted into the top of the insert rod 15 to make the mounting plate 1 more stable during installation. When installing the support base 14, the pull rod 44 is pulled to cause the locking block 42 to separate from the outer wall of the rotating rod 41, adjusting the angle between the support rod 12 and the support base 14. After adjustment, the pull rod 44 is released, and the locking block 42, under the action of the return spring 43, is inserted into the rotating rod 41 to fix the rotating rod 41, so that the support base 14 supports the mounting plate 1, making the guardrail able to withstand greater impact force and preventing it from tipping over.
