[0002] At present, there are safety issues in the construction of trestles and deep foundation pits at construction sites. Protective structures need to be set up on the edges of the construction sites to remind relevant personnel not to approach them, so as to avoid accidents.

[0003] For example, the patent website discloses an assembled guardrail with a warning function (publication number: CN220790860U). When the guardrail is placed, the two guardrails are not connected and fixed, which leads to poor integrity of the assembled guardrail. When one guardrail tilts, the other guardrails cannot help, which can easily cause one guardrail to fall over. Therefore, those skilled in the art have proposed a multi-purpose and multi-angle guardrail. Utility Model Content

[0025] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0030] Figure 5 A cross-sectional view of a fixing mechanism for a multi-purpose, multi-angle guardrail;

[0031] like Figure 1-4 As shown, a multi-purpose and multi-angle guardrail disclosed in the present invention may include: a guardrail mechanism, a connecting mechanism, a fixing mechanism and other components;

[0032] like Figure 1-4As shown, the railing mechanism includes a base 1, a vertical rod 2, a strip groove 3, a horizontal rod 4, and a telescopic plate 5;

[0033] Two bases 1 are arranged in parallel, each vertical rod 2 is installed at the center of the upper surface of the corresponding base 1, each strip groove 3 is opened on the side of the corresponding vertical rod 2, the ends of the two cross bars 4 are hinged inside the corresponding strip groove 3 and the other ends are hinged inside the other strip groove 3, and multiple telescopic plates 5 are evenly hinged on the lower surface of the corresponding cross bars 4 and the lower ends are hinged to the cross bars 4 below;

[0034] When in use, multiple railing mechanisms are neatly placed at the required positions on the construction site to achieve a protective effect. At the same time, the railing mechanism can also be placed on an inclined ground. Due to the inclination of the ground, the two bases 1 are at different heights, which in turn makes the two vertical rods 2 at different heights, and the two horizontal rods 4 tilt around the hinge. At the same time, during the tilting process, each telescopic plate 5 contracts, thereby realizing multi-angle adjustment of the railing mechanism, so that the device can adapt to the ground at various angles, has multiple uses, and increases the practicality of the device.

[0035] like Figure 1-4 As shown, it includes a cavity 6, a card slot 7, a limit plate 8, a plug-in 9, a spring 10, a lower slot 11, a winding rod 12, a wire rope 13, a card 14, a slot 15, and a first knob 25;

[0036] The cavity 6 is opened in the interior of one of the bases 1, the card slot 7 is opened on the side of the base 1 with the cavity 6 and is above the cavity 6, the limit plate 8 is slidably set in the interior of the cavity 6, the two plug-ins 9 are correspondingly installed on the upper surface of the limit plate 8 and extend into the card slot 7, the two springs 10 are arranged in the interior of the cavity 6 and are below the limit plate 8, the lower groove 11 is opened in the interior of the base 1 and is below the cavity 6, the winding rod 12 is rotatably installed in the lower groove 11, the wire rope 13 is installed in the center of the lower surface of the limit plate 8 and the lower end extends into the lower groove 11 and is fixedly connected to the winding rod 12, the first knob 25 is installed on the end of the winding rod 12 extending to the outside of the base 1, the clamp 14 is installed on the side of the other base 1 and is adapted to the card slot 7, and the two slots 15 are opened on the upper surface of the clamp 14 and are adapted to the plug-in 9;

[0037] When two devices are connected, the first knob 25 on one device can be rotated to drive the winding rod 12 to rotate. The rotating winding rod 12 winds the wire rope 13, thereby pulling the limit plate 8 down. The lowered limit plate 8 compresses the spring 10 and drives the two plug-ins 9 into the cavity 6. Then, the clamping member 14 of the other device is inserted into the clamping slot 7 of this device. When it is fully inserted, the two slots 15 of the clamping member 14 are just aligned with the two plug-ins 9. Then, the first knob 25 is released to allow the two springs 10 to rebound and drive the limit plate 8 to restore its position, thereby driving the two plug-ins 9 to be inserted into the two slots 15, fixing the clamping member 14, and then the two devices are connected by snapping. This allows the devices to be connected and fixed in pairs, making the integrity of multiple devices stronger after connection. At the same time, installation or disassembly is simple, and only one first knob 25 needs to be rotated, which is convenient for operation.

[0038] like Figure 1-4 As shown, the fixing mechanism includes a threaded barrel 17, a screw 18, a pointed rod 19, a limit block 20, a synchronous wheel 21, a synchronous belt 22, a second knob 23, and a through slot 24;

[0039] Each group of two threaded barrels 17 is mounted on both sides of the corresponding base 1, each screw 18 is rotatably mounted on the upper surface of the corresponding threaded barrel 17, each screw 18 is disposed in a hole of the corresponding threaded barrel 17, each pointed rod 19 is mounted on the lower end of the corresponding screw 18, each limit block 20 is disposed on the upper end of the corresponding screw 18, each through slot 24 is opened on the side of the corresponding base 1 and is above the card slot 7, each synchronous wheel 21 is mounted on the side of the corresponding threaded barrel 17 and is on one side of the through slot 24, a synchronous belt 22 is disposed on the corresponding two synchronous wheels 21 and passes through the through slot 24, and each second knob 23 is mounted on the side of one of the threaded barrels 17 of the corresponding group and is above the synchronous wheel 21;

[0040] When the devices are placed at a predetermined location on a construction site and connected in pairs, rotating the second knob 23 on each base 1 drives the corresponding threaded cylinder 17 to rotate. Then, the rotating threaded cylinder 17 drives the other threaded cylinder 17 to rotate in the same direction through the synchronous wheel 21 and the synchronous belt 22, driving the two screws 18 to descend, driving the two pointed rods 19 to descend and insert into the soil, thereby fixing the device on the ground and enhancing the stability of the device.
