Technical Field
[0001] This utility model relates to the field of anti-collision road barrier technology, and in particular to an anti-collision road barrier for road construction. Background Technology
[0002] Road engineering refers to the entire process of planning, designing, constructing, maintaining and managing roads, as well as the engineering entities involved. During road construction, road barriers need to be installed in advance to ensure construction safety. Road barriers are obstacles set up on the road, and their main function is to prevent vehicles from entering.
[0003] A search of Chinese patent CN221501784U reveals a road construction anti-collision barrier, comprising a support frame and a warning sign rotatably mounted thereon. A support mechanism is provided between the support frame and the warning sign. The support mechanism includes a support column rotatably mounted on the support frame and a sliding block slidably mounted on the rear side of the warning sign. One end of the sliding block is equipped with a buffer spring, one end of which supports the warning sign. One end of the support column is slidably connected to a sliding post, one end of which is rotatably connected to the sliding block. The other end of the sliding post is equipped with a buffer plate, which is slidably mounted inside the support column. A support spring is provided inside the support column. Through this designed support mechanism, during use, the support mechanism supports the warning sign and the reinforcing frame. In the event of a collision, the buffer spring and the elastic support spring of the support mechanism provide effective protection, reducing damage to the barrier and minimizing further damage.
[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned anti-collision road barriers: the existing anti-collision road barriers use springs to absorb the impact force during the collision, but when the spring is compressed, the elastic potential energy inside the spring is released, which will give the impacting object a rebound force, thereby ejecting the impacting object, which may lead to a secondary impact. Based on this, this utility model designs a road construction anti-collision road barrier to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a road construction anti-collision barrier to solve the problem mentioned in the background art that the existing technology is prone to causing the impacting object to bounce out and cause secondary impact.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a road construction anti-collision barrier, comprising a fixed base frame, on the top outer wall of the fixed base frame respectively, a protective baffle rotatably connected to the supporting base, and buffer components for supporting the protective baffle respectively installed on one side wall of the protective baffle.
[0007] A U-shaped base is hinged to the protective baffle. A guide base is installed on one side wall of the U-shaped base. A U-shaped base is hinged to the fixed base frame. A support rod is installed on one side wall of the U-shaped base. The support rod is slidably engaged with the guide base. Fixed protrusions are installed on one side wall of the support rod. A locking assembly for limiting the fixed protrusions is installed on the guide base.
[0008] As a preferred embodiment, the snap-fit assembly includes a U-shaped frame located on the guide base. Guide rods are respectively installed on one side wall of the U-shaped frame, and a guide base plate is slidably snapped onto the guide rod. A limit vertical plate is installed on one side wall of the guide base plate, and a compression spring is provided on the side wall of the guide rod.
[0009] As a preferred embodiment, the buffer assembly includes a U-shaped base three and a U-shaped base four. The U-shaped base three is hinged to the protective baffle, and the U-shaped base four is hinged to the fixed base frame. A guide sleeve is installed on one side wall of the U-shaped base three, and a guide post is installed on one side wall of the U-shaped base four. The guide sleeve and the guide post are movably engaged. A buffer spring is provided inside the guide sleeve.
[0010] As a preferred embodiment, guide blocks are respectively installed on the side walls of the guide posts, and the guide blocks are slidably engaged with the guide sleeves.
[0011] As a preferred embodiment, guide shafts are slidably engaged on the protective baffle, a protective panel is installed at one end of the guide shaft, and a support spring is provided on the side wall of the guide shaft.
[0012] As a preferred embodiment, reflective stickers are provided on one side wall of the protective panel.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] The impact force can be absorbed by the compression of the buffer spring, preventing direct damage to the roadblock. At the same time, the support rod can slide inside the guide base. Whenever the fixed protrusion on the support rod passes through the limiting vertical plate, the compression spring can drive the guide base plate to descend, so that the limiting vertical plate can limit the fixed protrusion, thereby preventing the buffer spring from causing the protective baffle to rebound, which helps to prevent the object from bouncing up and causing a secondary impact.

[0022] 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.
[0023] This utility model provides, for example Figure 1-6The road construction anti-collision barrier shown includes a fixed base frame 1. Support bases 2 are installed on the top outer wall of the fixed base frame 1. Protective baffles 3 are rotatably connected to the support bases 2. Buffer components 4 for supporting the protective baffles 3 are installed on one side wall of each protective baffle 3. A U-shaped base 5 is hinged to the protective baffle 3. A guide base 7 is installed on one side wall of the U-shaped base 5. A second U-shaped base 6 is hinged to the fixed base frame 1. A guide base 7 is installed on one side wall of the second U-shaped base 6. There is a support rod 8, which is slidably engaged with the guide base 7. Fixing protrusions 9 are respectively installed on one side wall of the support rod 8. A locking assembly 10 for limiting the fixing protrusions 9 is installed on the guide base 7. The locking assembly 10 includes a U-shaped frame 1001 located on the guide base 7. Guide rods 1002 are respectively installed on one side wall of the U-shaped frame 1001. A guide base plate 1003 is slidably engaged on the guide rods 1002. One side wall of the guide base plate 1003... A limiting vertical plate 1004 is installed on the top. A compression spring 1005 is provided on the side wall of the guide rod 1002. The buffer assembly 4 includes a U-shaped base three 401 and a U-shaped base four 402. The U-shaped base three 401 is hinged to the protective baffle 3, and the U-shaped base four 402 is hinged to the fixed bottom frame 1. A guide sleeve 403 is installed on one side wall of the U-shaped base three 401, and a guide post 404 is installed on one side wall of the U-shaped base four 402. The guide sleeve 403 and the guide post 404 are flexibly connected. The guide sleeve 403 has a buffer spring 405 inside. When the roadblock is impacted, the impacting object causes the protective baffle 3 to rotate, allowing the guide post 404 to slide within the guide sleeve 403. This compresses the buffer spring 405, enabling it to absorb the impact force and prevent direct damage to the roadblock. Simultaneously, the support rod 8 can slide within the guide base 7. Furthermore, since both the limiting vertical plate 1004 and the fixing protrusion 9 are equipped with guide ramps, such as... Figure 6 As shown, when the buffer spring 405 is compressed, the fixed protrusion 9 can push up the limiting vertical plate 1004. Whenever the fixed protrusion 9 on a support rod 8 passes through the limiting vertical plate 1004, the compression spring 1005 will drive the guide base plate 1003 to descend. By limiting the fixed protrusion 9 through the limiting vertical plate 1004, the buffer spring 405 can prevent the protective baffle 3 from rebounding, which helps to prevent secondary impact of the object. When the device is reused, by pulling the guide base plate 1003, the limiting vertical plate 1004 will no longer limit the fixed protrusion 9, so that the buffer spring 405 can lift the protective baffle 3 again.
[0024] In this embodiment, guide blocks 406 are respectively installed on the side wall of the guide post 404. The guide blocks 406 are slidably engaged with the guide sleeve 403. The guide blocks 406 can restrict the position of the guide post 404 and prevent the guide post 404 from coming out of the inside of the guide sleeve 403.
[0025] In this embodiment, a guide shaft 11 is slidably engaged on the protective baffle 3. A protective panel 12 is installed at one end of the guide shaft 11. A support spring 13 is provided on the side wall of the guide shaft 11. When the roadblock is slightly impacted, it first contacts the protective panel 12. The protective panel 12 drives the support spring 13 to buffer the slight impact and prevent the roadblock from being damaged.
[0026] In this embodiment, reflective stickers 14 are provided on one side wall of the protective panel 12. The reflective stickers 14 can remind vehicles to notice the roadblock at night.
[0027] Working principle of this utility model: This utility model is a road construction anti-collision barrier. When an object impacts, it first contacts the protective panel 12, thereby causing the protective baffle 3 to rotate. The impact force can be absorbed by the compression of the buffer spring 405, thus preventing the barrier from being directly damaged.
[0028] Meanwhile, the support rod 8 can slide inside the guide base 7. Whenever the fixed protrusion 9 on the support rod 8 passes through the limiting vertical plate 1004, the compression spring 1005 can drive the guide base plate 1003 to descend, so that the limiting vertical plate 1004 can limit the fixed protrusion 9, thereby preventing the buffer spring 405 from causing the protective baffle 3 to rebound, which helps to prevent secondary impact of the item.
[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
