Description

Technical Field

[0001] This utility model relates to the field of traffic guardrail technology, specifically a traffic guardrail that is easy to assemble and disassemble. Background Technology

[0002] In the field of traffic facilities, traffic guardrails are important facilities for ensuring road traffic safety and regulating the passage of vehicles and pedestrians. They have a wide range of applications, covering various environments such as urban roads, highways, and construction sections. However, traditional traffic guardrails have many inconveniences in actual use, especially in the installation and dismantling process.

[0003] Traditional guardrails often have a complex structural design, with components connected by welding or multiple sets of bolts. This not only requires specialized tools and a lot of manpower to complete the installation, but also makes the disassembly process time-consuming and labor-intensive when temporary adjustments, relocations, or repairs are needed, which greatly affects construction efficiency and increases maintenance costs.

[0004] In addition, when some guardrails are spliced ​​and expanded, the connection stability between adjacent units is insufficient, which can easily lead to problems such as loosening and shaking, affecting the overall protective performance of the guardrails.

[0005] According to the description in the patent announcement (authorization announcement number: CN222513143U) of a traffic guardrail that is easy to assemble and disassemble, the traffic guardrail includes "posts, crossbars" etc. to realize the installation and disassembly of the guardrail.

[0006] Regarding the above description, the applicant believes the following issues exist:

[0007] This easy-to-assemble and disassemble traffic barrier uses posts and crossbars to facilitate installation and disassembly. During use, the barrier provides protection through the longitudinal and transverse bars. However, when the longitudinal bars are bent due to collisions, they cannot be replaced. Furthermore, the barrier cannot be spliced ​​or expanded and can only be used individually, which affects its versatility. Therefore, this barrier needs to be improved. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution: a traffic guardrail that is easy to assemble and disassemble, including a counterweight base, a protective mechanism on the top of the counterweight base, and a warning mechanism on the top of the protective mechanism;

[0010] The protective mechanism includes a column fixedly connected to the top of a counterweight base. A first connecting block is slidably connected inside the column, and a bidirectional threaded rod is rotatably connected inside the column. A movable frame is threadedly connected to the periphery of the bidirectional threaded rod. An insert is fixedly connected to the top right side of the movable frame, and the insert is inserted into the column and the first connecting block. A guardrail frame is fixedly connected to the right side of the first connecting block. An upper rail is threadedly connected to the top inner side of the guardrail frame, and a lower rail is slidably connected to the periphery of the upper rail. A second connecting block is fixedly connected to the right side of the guardrail frame, and a connecting seat is slidably connected to the periphery of the second connecting block. A limit frame is inserted into the connecting seat, and a fixed shaft is threadedly connected to the inside of the limit frame.

[0011] Preferably, the movable frame is slidably connected to the inside of the column, the lower railing is threaded to the bottom of the inner side of the guardrail frame, and the bottom of the fixed shaft passes through the top of the connecting seat, so as to facilitate the movement of the insert block by the movable frame.

[0012] Preferably, the limiting frame extends through the interior of the second connecting block, and the top of the limiting frame contacts the top of the connecting seat, which facilitates the stability between the second connecting block and the connecting seat through the limiting frame, thereby enabling the splicing of two sets of guardrail frames.

[0013] Preferably, the movable frame and the insert are provided in two sets, and are symmetrically distributed on the upper and lower sides of the outer periphery of the bidirectional threaded rod. By providing two sets, the stability of the guardrail frame during installation can be guaranteed.

[0014] Preferably, the counterweight base, column, guardrail frame, bidirectional threaded rod, movable frame, insert block, first connecting block, upper railing, lower railing and second connecting block are provided in two sets, and are symmetrically arranged on the left and right sides of the connecting base, so that multiple sets of guardrail frames can be assembled by setting two sets.

[0015] Preferably, the warning mechanism includes a protective frame, which is disposed on the top of the column. A first warning strip is adhered to the left and right sides of the protective frame, and a second warning strip is adhered to the front and rear sides of the protective frame. A rectangular plate is fixedly connected to the bottom of the front and rear sides of the protective frame, and a limit shaft is threaded inside the rectangular plate.

[0016] Preferably, the limiting shaft passes through the inside of the column, the bottom of the protective frame is in contact with the top of the column and is located on the outer periphery of the top of the bidirectional threaded rod, and the protective frame, the first warning strip, the second warning strip, the rectangular plate and the limiting shaft are provided in two sets and are symmetrically distributed on the top of the two sets of columns, so that by setting two sets, the warning effect of the guardrail frame during use can be improved.

[0017] Compared with the prior art, this utility model provides a traffic guardrail that is easy to assemble and disassemble, and has the following beneficial effects:

[0018] 1. This easily assembled and disassembled traffic barrier features a protective mechanism. When the barrier is needed in traffic, the first connecting block is slidably connected to the inside of the post. Simultaneously, the interlocking of the insert block within the post and the first connecting block is easily achieved through the cooperation of the bidirectional threaded rod and the movable frame, quickly assembling the barrier frame and the post. The upper rail is then slidably connected to the inside of the lower rail, ensuring both rails are simultaneously inside the barrier frame. The upper and lower rails are threaded to the top and bottom of the inner side of the barrier frame, respectively. This facilitates replacement in case of damage or deformation due to collisions. The cooperation of the second connecting block and the connecting seat, along with the function of the limiting frame and the fixing shaft, makes the connection and separation of adjacent barrier frames simple and efficient, greatly reducing reliance on tools and manpower during installation and disassembly. The main components, such as the counterweight, post, and barrier frame, are provided in two sets, symmetrically distributed, allowing for the installation and disassembly of a single barrier frame as well as the easy splicing of multiple frames, making operation convenient.

[0031] This utility model provides the following technical solution:

[0032] Example 1

[0033] Please see Figure 1-7 This utility model provides a technical solution: a traffic guardrail that is easy to assemble and disassemble, including a counterweight 1, a protective mechanism 2 on the top of the counterweight 1, and a warning mechanism 3 on the top of the protective mechanism 2;

[0034] The protective mechanism 2 includes a column 21, which is fixedly connected to the top of the counterweight 1. A first connecting block 26 is slidably connected inside the column 21. A bidirectional threaded rod 23 is rotatably connected inside the column 21. A movable frame 24 is threadedly connected to the outside of the bidirectional threaded rod 23. An insert block 25 is fixedly connected to the top right side of the movable frame 24. The insert block 25 is inserted into the column 21 and the first connecting block 26. A guardrail frame 22 is fixedly connected to the right side of the first connecting block 26. An upper railing 27 is threadedly connected to the top of the inner side of the guardrail frame 22. A lower railing 28 is slidably connected to the outside of the upper railing 27. A second connecting block 29 is fixedly connected to the right side of the guardrail frame 22. A connecting seat 291 is slidably connected to the outside of the second connecting block 29. A limit frame 292 is inserted into the connecting seat 291. A fixed shaft 293 is threadedly connected inside the limit frame 292.

[0035] The movable frame 24 is slidably connected to the inside of the column 21, the lower railing 28 is threaded to the bottom of the inner side of the guardrail frame 22, and the bottom of the fixed shaft 293 passes through the top of the connecting seat 291, so that the movable frame 24 can drive the insert 25 to move.

[0036] The limiting frame 292 extends through the interior of the second connecting block 29, and the top of the limiting frame 292 contacts the top of the connecting seat 291, so that the stability between the second connecting block 29 and the connecting seat 291 can be ensured by the limiting frame 292, thereby enabling the splicing between the two sets of guardrail frames 22.

[0037] Two sets of movable frames 24 and insert blocks 25 are provided and symmetrically distributed on the upper and lower sides of the outer periphery of the bidirectional threaded rod 23. By setting two sets, the stability of the guardrail frame 22 during installation can be guaranteed.

[0038] The counterweight base 1, column 21, guardrail frame 22, bidirectional threaded rod 23, movable frame 24, insert block 25, first connecting block 26, upper railing 27, lower railing 28 and second connecting block 29 are provided in two sets, and are symmetrically located on the left and right sides of the connecting base 291, so that multiple sets of guardrail frames 22 can be assembled by setting two sets.

[0039] Example 2

[0040] Please see Figure 1-7 Furthermore, based on Embodiment 1, the warning mechanism 3 includes a protective frame 31, which is disposed on the top of the column 21. A first warning strip 32 is attached to the left and right sides of the protective frame 31, and a second warning strip 33 is attached to the front and rear sides of the protective frame 31. A rectangular plate 34 is fixedly connected to the bottom of the front and rear sides of the protective frame 31, and a limit shaft 35 is threadedly connected inside the rectangular plate 34.

[0041] The limiting shaft 35 passes through the inside of the column 21. The bottom of the protective frame 31 is in contact with the top of the column 21 and is located on the outer periphery of the top of the bidirectional threaded rod 23. The protective frame 31, the first warning strip 32, the second warning strip 33, the rectangular plate 34 and the limiting shaft 35 are provided in two sets and are symmetrically distributed on the top of the two sets of columns 21. By setting two sets, the warning effect of the guardrail frame 22 during use can be improved.

[0042] In actual operation, when this device is used and guardrails are needed in traffic, firstly, the first connecting block 26 is slidably connected to the inside of the post 21. Then, the double-threaded rod 23 is rotated. Through the cooperation of the double-threaded rod 23 and the moving frame 24, the moving frame 24 drives the insert block 25 to move, so that the insert block 25 is inserted into the inside of the post 21 and the first connecting block 26. This quickly completes the assembly between the guardrail frame 22 and the post 21. At the same time, the upper railing 27 is slidably connected to the inside of the lower railing 28, and both railings are simultaneously located inside the guardrail frame 22. The upper railing 27 and the lower railing 28 are respectively threaded to the top and bottom of the inside of the guardrail frame 22. This facilitates replacement when damage or deformation occurs due to collision.

[0043] Simultaneously, the connecting seat 291 is slidably connected to the inside of the second connecting block 29. When it is necessary to splice two guardrail frames 22, the first connecting block 26 of another set of guardrail frames 22 can be slidably connected to the inside of the connecting seat 291 at the same time, and the limiting frame 292 is inserted into the inside of the connecting seat 291 and passes through the inside of the second connecting block 29 and the first connecting block 26 of another set of guardrail frames 22, which can ensure the stability of the guardrail frame 22. At the same time, the fixing shaft 293 is threadedly connected to the inside of the limiting frame 292, and its bottom passes through the top of the connecting seat 291, which can ensure the stability of the limiting frame 292.

[0044] The cooperation between the second connecting block 29 and the connecting seat 291, along with the function of the limiting frame 292 and the fixed shaft 293, makes the connection and separation operation between adjacent guardrail frames 22 simple and efficient, greatly reducing the reliance on tools and manpower during installation and disassembly. The counterweight seat 1, column 21, guardrail frame 22, bidirectional threaded rod 23, moving frame 24, insert block 25, first connecting block 26, upper railing 27, lower railing 28 and second connecting block 29 are provided in two sets and symmetrically distributed, which can not only realize the installation and disassembly of a guardrail frame 22, but also facilitate the splicing of multiple guardrail frames 22, making the operation convenient.

[0045] After the guardrail frame 22 is installed, the bottom of the guardrail frame 31 is brought into contact with the top of the post 21. At the same time, the limiting shaft 35 is threaded into the inside of the rectangular plate 34 and passes through the inside of the post 21, which ensures the stability of the rectangular plate 34 and the guardrail frame 31. The first warning strips 32 on the left and right sides of the guardrail frame 31 and the second warning strips 33 on the front and rear sides can form obvious visual prompts to passing vehicles and pedestrians in different directions, improve the visibility of the guardrail, and reduce the probability of collision accidents. The guardrail frame 31 is fixed to the top of the post 21 through the limiting shaft 35, which ensures that the warning strips can maintain a good warning effect for a long time. At the same time, the top part of the bidirectional threaded rod 23 can be protected under the action of the guardrail frame 31.

[0046] After installation, the counterweight base 1 can be fixed by external fixing equipment to ensure the stability of the column 21.
