[0001] The utility model relates to the technical field of guardrails, in particular to a multifunctional safety guardrail for road construction. Background Art

[0002] Road construction guardrails are an important traffic safety facility, primarily used to protect construction sites during road construction, ensuring construction safety while minimizing traffic impacts. These guardrails are typically installed around construction areas to separate them from non-construction areas, preventing pedestrians or vehicles from mistakenly entering the construction site and causing accidents. The design and installation of road construction guardrails must comply with relevant safety standards and regulations to ensure their effectiveness and safety. There are various types of road construction guardrails, including corrugated guardrails, construction site safety guardrails, and engineering guardrails. These guardrails typically use anti-corrosion treatments such as paint or plastic spraying to increase their durability and service life. Furthermore, the installation and use of road construction guardrails must comply with strict safety regulations to ensure the safety of construction workers and passers-by.

[0003] In the prior art, a Chinese patent with publication number CN216949804U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A safety guardrail for road construction, comprising: a railing, both sides of the railing are fixedly connected with a column, the bottom end of the column is fixedly connected to a mounting plate; a clamping assembly for clamping and installing adjacent guardrails, the clamping assembly is arranged on the side of one of the columns; the clamping assembly can quickly clamp adjacent devices, avoid the use of traditional bolts, reduce the difficulty of installation, and save installation time, thereby improving installation efficiency and installation.

The reinforcement component can reinforce the snap-on component, thereby increasing the stability of the device. However, although the guardrail of the above-mentioned patent can connect two adjacent guardrails, when encountering special road conditions, it is not convenient to use the guardrails in an irregular manner. The applicable scenarios are relatively single, the scope of application of the guardrail is small, and it is inconvenient to use. Utility Model Content

[0004] The purpose of the present utility model is to provide a multifunctional safety guardrail for road construction to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A multifunctional safety guardrail for road construction comprises a guardrail, two upright posts, a mounting shell and two adjustment components.

[0007] The two posts are fixedly connected to the two sides of the railing respectively; the mounting shell is fixedly installed on the surface of one of the posts; the adjustment component is arranged inside the mounting shell; the adjustment component includes a turning wheel, a gear, a rack, a positioning slide, and a limit insert; one end of the turning wheel passes through the mounting shell and is fixedly connected to the gear, the gear is meshed with the rack, the rack is slidably connected to the positioning slide, the positioning slide is fixedly installed on the inner wall of the mounting shell, and the bottom end of the rack is fixedly installed with a limit insert.

[0008] By adopting the above technical solution, multiple adjacent guardrails can be enclosed into irregular shapes, so that they can be used for special maintenance sections. When multiple guardrails are combined and enclosed, the angle can be adjusted through the adjustment component, so that the guardrails can be used for different construction sites. By setting the adjustment component, it is convenient to adjust the angle of adjacent guardrails, which can expand the scope of use of the guardrails.

[0009] A further improvement of the technical solution of the present invention is that it also includes an "L"-shaped plug rod, which is fixedly installed on one side of another column; and a "cross" plug block is installed at the bottom end of the "L"-shaped plug rod.

[0010] The above technical solution is adopted, in which the "L"-shaped plug rod is "L"-shaped, which is convenient for assembly between two adjacent guardrails, and enables multiple guardrails to be used to enclose the road site, thereby leaving space for rotation and adjustment between adjacent guardrails.

[0011] A further improvement of the technical solution of the present invention is that it also includes a rotating clamping block, which is rotatably mounted on the bottom of the inner cavity of the mounting shell; and a limiting groove is provided on the surface of the rotating clamping block for engaging with the limiting inserting strip.

[0012] The above technical solution is adopted, in which the rotating clamp is rotatably connected to the bottom of the inner cavity of the installation shell through a movable shaft. Therefore, when two adjacent guardrails are clamped together, the angle of the guardrail can be adjusted by rotating the rotating clamp.

[0013] A further improvement of the technical solution of the present utility model is that a "cross" slot for engaging with the "cross" inserting block is provided on the surface of the rotating clamping block.

[0014] By adopting the above technical solution, two adjacent guardrails can be connected by snapping, and the shape of the "cross" plug-in block matches the opened "cross" slot. When the "cross" plug-in block is located inside the "cross" slot, it can be rotated and adjusted by turning the block, thereby facilitating the adjustment of the angle of the guardrail.

[0015] A further improvement of the technical solution of the present invention is that a limiting slot movably connected to the "L"-shaped plug rod is provided on the top of the installation shell.

[0016] By adopting the above technical solution, the limiting slot opened at the top of the mounting shell can just allow the "L"-shaped rod to be embedded in the interior of the mounting shell for installation. By opening the limiting slot, external impurities can be prevented from entering the interior of the mounting shell and affecting use.

[0017] A further improvement of the technical solution of the utility model is that it also includes a marking plate fixedly installed on the surface of the railing.

[0018] By adopting the above technical solution, the signboard is fixedly mounted on the railing, and warning signs can be posted on the signboard to serve as a warning to passers-by.

[0019] A further improvement of the technical solution of the utility model is that it also includes a reflector fixedly installed at the bottom end of the railing.

[0020] The above technical solution is adopted, in which a plurality of reflective strips are posted on the surface of the reflective plate, which can reflect the surrounding light at night, thereby playing a certain warning role for passers-by and drivers.

[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0022] 1. The utility model provides a multifunctional safety guardrail for road construction. By setting an adjustment component, the angle of the adjacent guardrails can be adjusted, so that it can be used for maintenance of different road conditions, so that multiple guardrails can be surrounded in an irregular manner, which can expand the scope of use of the guardrail and achieve better results.

[0023] 2. The utility model provides a multifunctional safety guardrail for road construction. By connecting the "cross" plug-in block to the inside of the "cross" slot, the guardrails can be rotated and adjusted under the action of the rotating block, so that the angle between the guardrails can be adjusted after the connection, which makes the operation more convenient.

[0032] The present invention is further described in detail below with reference to the embodiments:

[0033] Example 1

[0034] like Figure 1-6 As shown, the utility model provides a multifunctional safety guardrail for road construction, including a guardrail 1, two upright posts 2, a mounting shell 4, and two adjustment components 5.

[0035] The two columns 2 are fixedly connected to both sides of the railing 1 respectively; the mounting shell 4 is fixedly mounted on the surface of one of the columns 2 .

[0036] The adjusting assembly 5 is arranged inside the mounting shell 4; the adjusting assembly 5 includes a turning wheel 501, a gear 502, a rack 503, a positioning slide 504, and a limiting insert 505; one end of the turning wheel 501 passes through the mounting shell 4 and is fixedly connected to the gear 502, the gear 502 is meshed with the rack 503, the rack 503 is slidingly connected to the positioning slide 504, the positioning slide 504 is fixedly installed on the inner wall of the mounting shell 4, and the bottom end of the rack 503 is fixedly installed with the limiting insert 505.

[0037] In this embodiment, the columns 2 installed on both sides can support the installation of the railing 1 with stability. A mounting plate 3 is installed at the bottom of each column 2, which can be fixed to the road surface through the mounting plate 3 when the guardrail is used to protect the road construction site, and fixing bolts are installed at the four ends of the surface of each mounting plate 3, so that the fixing bolts can tighten the support of the column 2. The mounting shell 4 can protect the setting of the adjustment component 5 to prevent the adjustment component 5 from being damaged by long-term exposure to the outside world.

[0038] One end of the screw wheel 501 can pass through the mounting shell 4 and be fixedly connected with the gear 502. Therefore, by screwing the screw wheel 501, the gear 502 can be driven to rotate, and the gear 502 is meshed with the rack 503, so that the gear 502 can drive the rack 503 to move up and down while rotating. A groove is provided on one side of the positioning slide 504 for easy sliding of the rack 503. When the rack 503 is driven to move by the rotation of the gear 502, it can slide back and forth in the groove provided on the positioning slide 504. At this time, the positioning slide 504 can limit the rack 503. A limiting insert 505 is installed at the bottom end of the rack 503. The rack 503 can drive the limiting insert 505 to move and be used, which is convenient for locking between two adjacent guardrails.

[0039] like Figure 1-6 As shown, in this embodiment, preferably, an "L"-shaped plug rod 7 is further included, which is fixedly installed on one side of another column 2; a "cross" plug block 701 is installed at the bottom end of the "L"-shaped plug rod 7. The "L"-shaped plug rod 7 is in an "L" shape. When one end of the "L"-shaped plug rod 7 enters the mounting shell 4, so that two adjacent guardrails are clamped together, the angle generated by the "L"-shaped plug rod 7 can be sufficient to adjust the angle of the two guardrails after clamping, thereby facilitating multi-angle adjustment between the two guardrails. The bottom end of the "L"-shaped plug rod 7 is installed with a "cross" plug block 701. The "cross" plug block 701 is in a "cross" shape, which facilitates the clamping and assembly of two adjacent guardrails.

[0040] like Figure 1-6 As shown, preferably, it also includes a rotating block 6, which is rotatably mounted at the bottom of the inner cavity of the mounting shell 4; the surface of the rotating block 6 is provided with a limiting groove 602 that engages with the limiting insert 505. The rotating block 6 is rotatably connected to the bottom of the inner cavity of the mounting shell 4 via a movable shaft. At this time, the limiting groove 602 is provided at the top of the rotating block 6. When the guardrails between two adjacent guardrails are adjusted, the limiting insert 505 can be driven to insert into the limiting groove 602 by turning the wheel 501. Since the bottom end of the limiting insert 505 is rectangular and the limiting groove 602 is provided with a circular groove, the limiting insert 505 can be inserted into the limiting groove 602 to position the rotating block 6. The size of the limiting insert 505 can be just inserted into the limiting groove 602 provided below, so that after the rotating block 6 is rotated, it can be locked at any time.

[0041] like Figure 1-6 As shown, preferably, a "cross" slot 601 is provided on the surface of the rotating block 6 to be engaged with the "cross" plug-in block 701. The shape of the "cross" slot 601 provided on the surface of the rotating block 6 is consistent with that of the "cross" plug-in block 701, and the "cross" plug-in block 701 can match the "cross" slot 601, so that when the "cross" plug-in block 701 is inserted into the "cross" slot 601, the "L"-shaped plug-in rod 7 can be limited and placed. Since the "cross" plug-in block 701 is in a "cross" shape, when the "cross" plug-in block 701 is limited inside the "cross" slot 601, the "L"-shaped plug-in rod 7 can be rotated. At this time, after the "cross" plug-in block 701 is inside the "cross" slot 601, the rotating block 6 can be rotated, thereby facilitating the adjustment of the angle between adjacent engaged guardrails.

[0042] like Figure 1-6 As shown, preferably, a limiting slot 401 movably connected to the "L"-shaped plug rod 7 is provided on the top of the mounting shell 4. The limiting slot 401 is provided on the top of the mounting shell 4 to facilitate the connection between two guardrails, so that the "L"-shaped plug rod 7 is just embedded in the interior of the mounting shell 4. The size of the limiting slot 401 is only sufficient to allow the "L"-shaped plug rod 7 to be embedded. When adjacent guardrails are connected, the space in the limiting slot 401 is filled with the "L"-shaped plug rod 7, which can prevent impurities from falling into the interior of the mounting shell 4 during use of the guardrails, thereby preventing the internal components of the mounting shell 4 from being disturbed.

[0043] like Figure 1-6 As shown, preferably, a sign plate 8 is further included, which is fixedly mounted on the surface of the guardrail 1. The sign plate 8 is fixedly mounted on the guardrail 1, and the position where the sign plate 8 is mounted belongs to the front of the guardrail. When the guardrail protects the road site, a warning sign can be attached to the sign plate 8, thereby being able to warn passing pedestrians and vehicles.

[0044] like Figure 1-6 As shown, preferably, a reflector 9 is further included, which is fixedly mounted on the bottom end of the railing 1. A plurality of reflective strips are mounted on the surface of the reflector 9, which can be used at night to reflect ambient light, thereby providing a certain warning to passers-by and drivers.

[0045] The following is a detailed description of the working principle of the multifunctional safety guardrail for road construction.

[0046] like Figure 1-6As shown, after the guardrail is moved to the road construction site, the adjacent guardrails are connected, one of the guardrails is lifted, and the "L"-shaped plug rod 7 is inserted into the interior of the limit slot 401, so that the "cross" plug block 701 is embedded in the interior of the "cross" card slot 601. At this time, according to the needs of the on-site road construction, the angle of the adjacent guardrails is adjusted, and the guardrails are moved and adjusted. Since the "cross" plug block 701 is embedded in the interior of the "cross" card slot 601, the guardrail can be rotated by rotating the card block 6 during adjustment. After the adjustment is completed, the two twisting wheels 501 on both sides can be turned so that the twisting wheels 501 are moved. The movable gear 502 rotates and pushes the rack 503 to move downward, so that the limiting insert 505 at the bottom end of the rack 503 is embedded in the limiting groove 602. The two limiting inserts 505 can be respectively located on both sides of the limiting groove 602. At this time, the rotation of the rotating block 6 can be limited so that the rotating block 6 is no longer driven to rotate, thereby positioning and placing the adjacent guardrails. By setting the adjustment component 5, the angle between the guardrails can be adjusted for different road construction sites, and the angle between the adjacent guardrails can be fixed and locked after adjusting, so that the multiple guardrails are irregularly surrounded, thereby expanding the scope of use of the guardrails.

[0047] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
