Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a safety warning barrier. Background Technology

[0002] In subway construction, safety warning barriers are a key safety protection facility, mainly used to isolate dangerous areas, warn of operational risks, and regulate personnel behavior to ensure construction safety and subway operation safety.

[0003] In the current use of safety warning barriers, on construction sites, the barriers need to be flexibly assembled according to actual needs. The conventional assembly method involves pre-drilling bolt holes at the joints of the barrier posts or crossbars. During assembly, the corresponding parts of adjacent barriers are precisely aligned, and then bolts, nuts, and washers are used with tools to tighten the connection, thus completing the construction of the warning barrier. However, when the construction progress changes and the position of the warning barrier needs to be adjusted or it needs to be removed, new problems arise. At this time, it is necessary to unscrew the bolts one by one with tools. During the disassembly process, small parts such as bolts, nuts, and washers are easily lost, and the entire disassembly operation is complicated and time-consuming, which will adversely affect the orderly progress of construction and reduce construction efficiency.

[0015] 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.

[0016] Please see Figure 1-5 As shown, a safety warning barrier includes a first guardrail 1 and a second guardrail 2 located on the side away from the first guardrail 1. The first guardrail 1 and the second guardrail 2 have the same appearance and design, and are both warning barriers of the same specifications. It also includes a connecting mechanism 3 for quick assembly and disassembly of the warning barrier, located between the first guardrail 1 and the second guardrail 2. The connecting mechanism 3 includes a connecting seat 31, a mounting seat 32, a rotating component 34, a first locking block 35, a second locking block 36, and a limiting component 38. The connecting seat 31 is fixed to the outside of the first guardrail 1, the mounting seat 32 is fixed to the outside of the second guardrail 2, the rotating component 34 is located to the outside of the mounting seat 32, and the first locking block... The first guardrail 1 and the second guardrail 2 are both fixed to the right side of the rotating component 34 and the left side of the connecting seat 31. The first guardrail 1 and the second guardrail 2 are both fixed to the right side of the mounting seat 32 and the left side of the connecting seat 31. This design facilitates the splicing of the two warning guardrails. The limiting component 38 is located inside the second guardrail 36. The connecting mechanism 3 also includes a positioning component 33, a reset component 37 and an adjustment component 39. The positioning component 33 is located inside the first guardrail 35, the reset component 37 is located outside the second guardrail 36 and the adjustment component 39 is located outside the reset component 37.

[0017] The positioning component 33 includes a positioning block 331 fixed to the outside of the second locking block 36. A connecting groove 332 is provided on the inner wall of the first locking block 35. The outer side of the positioning block 331 engages with the inner wall of the connecting groove 332. When assembling the two sets of warning rails, the positioning block 331 is first aligned and inserted into the connecting groove 332 to position the connection between the first locking block 35 and the second locking block 36, allowing them to smoothly complete the rotational connection. The rotating component 34 includes a guide rail 341 fixed to the outside of the mounting base 32. A connecting ring 342 is rotatably connected to the outer side of the 1. Two first locking blocks 35 are fixedly connected to the outer side of the connecting ring 342. The first locking blocks 35 can rotate along the outer side of the guide rail 341 through the connecting ring 342, thereby forming a rotational engagement with the second locking block 36, so that the two sets of warning bars are fixed together. The reset assembly 37 includes a fixing frame 371 fixed to the outer side of the second locking block 36. Two guide rods 372 are slidably connected to the inner wall of the fixing frame 371. A spring 373 is fixedly connected to the inner side of the fixing frame 371. 2 can slide parallel to the inner wall of the fixed frame 371. Simultaneously, the spring 373, after being compressed, accumulates elastic force, pushing the object connected to one end to move. The limiting assembly 38 includes a locking block 381 fixed to one end of the guide rod 372, one side of which is fixedly connected to one end of the spring 373. A limiting groove 382 is formed through the inner wall of the first locking block 35. The outer side of the locking block 381 engages with the inner wall of the limiting groove 382. A limiting block is fixedly connected to one side of the second locking block 36 to limit the movement range of the first locking block 35. The locking block 381 is aligned with the limiting groove 382. When the locking block 381 enters the inner side of the limiting groove 382, ​​the second locking block 36 and the first locking block 35 will form a fixed connection. The adjusting assembly 39 includes a transmission rod 391 fixed to the other end of the guide rod 372. The other end of the transmission rod 391 is fixedly connected to an adjusting ring 392. The adjusting ring 392 is circular in shape and its outer side is connected to two sets of transmission rods 391. It is used to make the transmission rod 391 drive the locking block 381 to move through the guide rod 372.

[0018] Working principle: In use, when the warning barrier needs to be assembled, first align the positioning block 331 and insert it into the connecting slot 332 to complete the initial connection between the connecting seat 31 and the mounting seat 32. During this process, the first locking block 35 needs to be offset from the second locking block 36. Then, with the attached... Figure 3From the perspective of the first hand, rotate the first locking block 35 counterclockwise so that it rotates along the outside of the guide rail 341 through the connecting ring 342. With the other hand, pull the adjusting ring 392 towards the mounting base 32. Then, the first locking block 35 rotates into the inside of the second locking block 36. After the first locking block 35 touches the limit block, it stops rotating and engages with the second locking block 36. At this time, release the adjusting ring 392. The spring 373 loses its limit and pushes the locking block 381 into the inside of the limit groove 382 through its rebound force, so that the second locking block 36 and the first locking block 35 form a fixed connection, and the assembly of the warning barrier can be completed. When the warning barrier needs to be separated, first pull the adjusting ring 392 towards the mounting base 32 so that the transmission rod 391 drives the locking block 381 out of the inside of the limit groove 382 through the guide rod 372. Then, rotate the first locking block 35 clockwise, and the first locking block 35 will separate from the second locking block 36. Then, pull out the positioning block 331 to complete the disassembly.
