Description

Technical Field

[0001] This utility model relates to the field of construction guardrail technology, and in particular to a foldable construction edge guardrail. Background Technology

[0002] During highway or bridge construction, guardrails are typically erected near the construction area to isolate and protect its edges, preventing unauthorized personnel or vehicles from entering and disrupting construction work. However, existing construction guardrails are inconvenient to assemble and disassemble. Each guardrail panel needs to be removed individually, leaving no connection between them. Subsequent assembly requires reinstalling each panel individually, which is quite cumbersome. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the existing technology requires all guardrail panels to be removed and installed one by one, which increases the difficulty of installation and removal work, and proposes a foldable construction edge protection railing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a foldable construction edge protection railing, including a guardrail panel and a railing. The guardrail panel has inserts fixedly installed on both sides, and the railing has fixed seats fixedly installed on both sides. The fixed seats have a rotating shaft rotatably installed inside. The rotating shaft extends through to both ends of the fixed seat and has a limit plate fixedly installed on each end. The upper limit plate is threaded with a first bolt. The lower end of the insert passes through the limit plate and the rotating shaft. The bottom of the railing is fixedly installed with a base.

[0006] Preferably, the outer edge cross-section of the rotating shaft is circular and the inner edge cross-section is square, and the cross-section of the insertion rod is square.

[0007] Preferably, the central axis of the rotating shaft coincides with the central axis of the lower end of the insertion rod.

[0008] Preferably, the first bolt is eccentrically disposed on the surface of the limiting disc, and at least three grooves are provided on the upper end face of the rotating shaft. The bottom of the first bolt is threadedly connected to the inside of the groove, and the grooves are distributed in a circumferential array along the central axis of the rotating shaft.

[0009] Preferably, both the rotating shaft and the lower end of the insertion rod extend to the bottom of the fixed base, and a second bolt is threaded onto one side of the rotating shaft, with the end of the second bolt abutting against the insertion rod.

[0010] Preferably, a positioning screw is threaded to one side of the base, the lower end of the railing extends into the interior of the base and is fixedly installed with a movable block, and a roller is fixedly installed on the lower surface of the movable block.

[0011] Preferably, a matching magnet block is fixedly installed on the inner wall surface of the lower end of the movable block that contacts the base.

[0012] Preferably, a lighting lamp is fixedly installed at the upper end of the railing.

[0013] The present invention proposes a foldable construction edge protection railing, the advantages of which are as follows: During installation, the insert rod on one side of the railing can be inserted into the rotating shaft on the other side of the railing. The insert rod is secured by a second bolt to prevent it from separating from the rotating shaft. The first bolt is threadedly connected to the groove, allowing the rotation direction of the rotating shaft to be adjusted according to specific installation requirements, thereby adjusting the installation angle of the railing. During installation, the angle of the railing can be adjusted as needed, making installation highly convenient. During dismantling, the first bolt is separated from the groove, allowing the railing to be rotated and folded at will. Multiple layers of the railing can be stacked sequentially, reducing the overall space occupied by the edge protection railing and facilitating transportation and storage. Of course, the number of railings stacked should not be excessive. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figures 1-4 and Figure 7 A foldable construction edge protection fence includes a guardrail panel 1 and a railing 2, both of which are standard features of existing guardrails. A base 3 is fixedly installed at the bottom of the railing 2, providing stable support. A lighting lamp 10 is fixedly installed at the top of the railing 2. At night, the lighting lamp 10 can roughly display the overall outline of the guardrail, allowing nearby pedestrians and vehicles to quickly identify its location.

[0024] The guardrail 1 has two fixedly installed insert rods 8 on both sides, and the guardrail 2 has two fixedly installed fixed seats 4 on both sides. A rotating shaft 5 is rotatably mounted inside the fixed seat 4. The lower end of the insert rod 8 passes through a limiting flange 6 and the rotating shaft 5. The central axis of the rotating shaft 5 coincides with the central axis of the lower end of the insert rod 8. The outer edge of the rotating shaft 5 has a circular cross-section, and the inner edge has a square cross-section. The insert rod 8 has a square cross-section. When the insert rod 8 is inserted inside the rotating shaft 5, it cannot rotate within the rotating shaft 5, but the rotation of the rotating shaft 5 can drive the insert rod 8 to rotate. Limiting flanges 6 are fixedly installed at both ends of the rotating shaft 5 extending to the outer side of the fixed seat 4. The limiting flanges 6 restrict the position of the rotating shaft 5, allowing it to rotate only within the fixed seat 4, and preventing it from detaching from the fixed seat 4.

[0025] A first bolt 7 is threaded onto the surface of the upper limiting edge disc 6. The first bolt 7 is eccentrically positioned on the surface of the limiting edge disc 6. At least three grooves 71 are formed on the upper end face of the rotating shaft 5. The bottom of the first bolt 7 is threaded into the inside of the groove 71, and the grooves 71 are arranged in a circumferential array along the central axis of the rotating shaft 5. When the first bolt 7 is threaded into any groove 71, the position of the upper limiting edge disc 6 is fixed, thereby fixing the rotating shaft 5 and preventing it from rotating within the fixing seat 4. Because the grooves 71 are arranged in different directions, the rotating shaft 5 can be fixed in different directions, thus limiting the installation angle of the guardrail 1. The angle between the two guardrails 1 can be 180°, 90°, or 270°, depending on the specific installation requirements. The number of grooves 71 can even be increased, allowing the angle between the two guardrails 1 to be 30°, 45°, or 135°, making the edge protection railing suitable for more special areas.

[0026] The lower ends of the rotating shaft 5 and the insert rod 8 both extend to the bottom of the fixed seat 4, and a second bolt 9 is threadedly connected to one side of the rotating shaft 5. The end of the second bolt 9 abuts against the insert rod 8. When the second bolt 9 abuts against the insert rod 8, the insert rod 8 is fixed inside the rotating shaft 5, so that the two guardrail panels 1 can be connected together.

[0027] Working Principle: During installation, the foldable construction edge protection railing inserts the rod 8 on one side of the guardrail panel 1 into the rotating shaft 5 on one side of the guardrail panel 2. The second bolt 9 secures the rod 8, preventing it from separating from the rotating shaft 5. The rod 8 is threadedly connected to the groove 71 via the first bolt 7. The rotation direction of the rotating shaft 5 can be adjusted according to specific installation requirements, thus adjusting the installation angle of the guardrail panel 1. During installation, the angle of the guardrail panel 1 can be adjusted as needed, offering high installation convenience. When dismantling the edge protection railing, the first bolt 7 can be rotated to separate it from the groove 71, allowing the guardrail panel 1 to be rotated freely. The rod 8 remains fixed within the rotating shaft 5 via the second bolt 9. Multiple guardrail panels 1 form a stable whole. With the guardrail panel 1 still attached to the guardrail panel 2, it can be folded by rotating it, allowing multiple layers of the guardrail panel 1 to be stacked sequentially. The top view of the folded guardrail panel 1 is shown in the attached figure. Figure 7 As shown, this design can reduce the overall space occupied by the edge protection railing, making it easier to transport and store. It is also more convenient during the later installation process. Of course, the number of railing panels 1 stacked should not be too many. After stacking an appropriate number of layers, the second bolt 9 can be removed, and the insert rod 8 can be moved out of the rotating shaft 5. The railing panel 1 can then be removed from the railing panel 2. The number of layers of the railing panel 1 can be adjusted according to the specific situation. All railing panels 1 can be disassembled to meet different disassembly, transportation, and storage needs.

[0028] Example 2: In Example 1, since the bottom of the base 3 is in contact with the ground, during the folding of the guardrail panel 1, the base 3 is generally pushed to move, causing the guardrail panels 1 to fold together. However, this results in excessive friction between the base 3 and the ground, which is not only laborious but also prone to damaging the ground. Therefore, this example is proposed. (Refer to...) Figures 5-6 As another preferred embodiment of this utility model, based on embodiment 1, a positioning screw 33 is threadedly connected to one side of the base 3. The depth of the positioning screw 33 into the base 3 can be adjusted by rotating the positioning screw 33. The lower end of the railing 2 extends into the interior of the base 3 and a movable block 31 is fixedly installed. A roller 32 is fixedly installed on the lower surface of the movable block 31. When the positioning screw 33 is rotated into the interior of the movable block 31, the roller 32 is hidden inside the base 3. When the positioning screw 33 is rotated away from the movable block 31, it will not affect the movement of the movable block 31.

[0029] As attached Figure 5 As shown, the movable block 31 is located at the top of the inner side of the base 3. At this time, the positioning bolt 33 can be inserted into the movable block 31. The roller 32 is hidden inside the base 3. The base 3 is in contact with the ground. The guardrail is supported by the base 3 and is relatively stable.

[0030] As attached Figure 6 As shown, at this point, the movable block 31 is disengaged from the positioning bolt 33, and the bottom of the roller 32 extends to below the base 3. A cooperating magnet 34 is fixedly installed on the inner wall surface of the movable block 31 where it contacts the base 3. The magnet 34 allows the base 3 and the movable block 31 to attract each other, preventing the base 3 from falling downwards and affecting the movement of the roller 32. At this point, the entire guardrail is supported by the roller 32, and pushing the guardrail makes it easy to fold.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
