DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0023] like Figures 1 to 6 As shown, a portable detachable guardrail net includes a frame 1, and a first support column 3 and a second support column 4 are respectively arranged on both sides of the frame 1, and a placement slot 13 is opened on the side wall opposite to the first support column 3 and the second support column 4, and the two placement slots 13 are respectively provided with chamfers 14 on the first support column 3 and the second support column 4, and the inner cavity of the frame 1 is provided with two mutually symmetrical slots, and the guardrail net 2 is fixedly installed in the inner cavities of the two slots, and two mutually symmetrical clamping slots 8 are also opened on the top of the frame 1, a rotating mechanism is set on the side wall of the first support column 3 close to the second support column 4, and a clamping mechanism is set on the side wall of the second support column 4 close to the first support column 3. When disassembly is required, the arc plate 7 is pulled, and the plug-in slot 11 and the plug-in rod 12 provided in the fixed block 10 installed on the arc plate 7 are squeezed under the action of the squeezing force. At this time, the plug-in rod 12 slowly moves backwards with the assistance of the sliding mechanism until the plug-in rod 12 and the plug-in slot 11 are separated. At this time, the frame 1 can be disassembled, so it is more convenient to a certain extent than bolt installation.

[0024] In a specific embodiment, the rotating mechanism includes four arc-shaped plates 7, and a rotating shaft 6 is provided on one side wall of the four arc-shaped plates 7 close to the first supporting column 3. Both ends of the four rotating shafts 6 are rotatably connected to baffles 5, and each baffle 5 is fixedly connected to the first supporting column 3. In this configuration, the installation position and components of the rotating mechanism are determined.

[0025] Furthermore, a plurality of clamping rods 9 are fixedly mounted on each of the four arc-shaped plates 7 near one side wall of the frame 1, and the length of each clamping rod 9 gradually decreases from the middle to both sides, and each clamping rod 9 is respectively clamped in the inner cavity of the clamping slot 8. In this configuration, the installation position and components of the clamping rod 9, as well as the relationship between the clamping rod 9 and the clamping slot 8 are determined.

[0026] Furthermore, the clamping mechanism includes four rectangular slots 15, which are respectively opened on a side wall of the second support column 4 close to the first support column 3, and the inner cavities of the four rectangular slots 15 are all provided with sliding mechanisms and plug-in rods 12. In this configuration, the installation position and components of the clamping mechanism are determined.

[0027] Furthermore, the sliding mechanism includes a plurality of slide grooves 17, each of which is respectively provided on two opposite side walls of the inner cavity of the rectangular slot 15, each of which is symmetrical with each other, and each of which has a sliding block 18 slidably mounted in the inner cavity of each slide groove 17, each of which is symmetrical with each other, and one side wall of each of which is opposite to each other is connected to the plug-in rod 12. In this configuration, the installation position and components of the sliding mechanism are determined.

[0028] Furthermore, a fixing block 10 is fixedly installed on one end of the four arc-shaped plates 7 close to the second support column 4, and a plug-in groove 11 is opened on a side wall of the four fixing blocks 10 close to the second support column 4. Each plug-in groove 11 and the plug-in rod 12 fit together, and a return spring 16 is fixedly installed on a side wall of each plug-in rod 12 away from the plug-in groove 11, and one end of each return spring 16 away from the plug-in rod 12 is fixedly connected to the inner wall of the rectangular notch 15. In this setting, when the frame 1 is installed, the staff rotates the arc plate 7 (the arc plate 7 can rotate with the assistance of the rotating mechanism). When the arc plate 7 rotates, it can drive the fixed block 10 to rotate together. When the fixed block 10 rotates to a certain position, it can squeeze the plug rod 12 to move with the assistance of the sliding mechanism until the plug rod 12 and the plug groove 11 opened on the fixed block 10 fit each other. At this time, the plug rod 12 can be inserted into the plug groove 11 with the assistance of the reset spring 16 and the sliding mechanism for limiting. At the same time, when the arc plate 7 moves, it can drive the clamping rod 9 to clamp into the clamping groove 8 opened on the frame 1, so that the frame 1 can be limited, thereby facilitating its installation to a certain extent.

[0029] The implementation principle of a portable detachable guardrail net of this embodiment is as follows: first, the frame 1 is installed on the first support column 3 and the second support column 4. Because the first support column 3 and the second support column 4 are provided with placement slots 13, and the placement slots 13 are provided with chamfers 14, it is convenient to install the frame 1;

[0030] When the frame 1 is installed, the staff rotates the arc plate 7 (the arc plate 7 can be rotated with the assistance of the rotating mechanism). When the arc plate 7 rotates, it can drive the fixed block 10 to rotate together. When the fixed block 10 rotates to a certain position, it can squeeze the plug rod 12 to move with the assistance of the sliding mechanism until the plug rod 12 and the plug groove 11 provided on the fixed block 10 fit each other. At this time, the plug rod 12 can be inserted into the plug groove 11 with the assistance of the reset spring 16 and the sliding mechanism for limiting. At the same time, when the arc plate 7 moves, it can drive the clamping rod 9 to clamp in the clamping groove 8 provided on the frame 1, so that the frame 1 can be limited, thereby facilitating its installation to a certain extent.

[0031] When disassembly is required, the arc plate 7 is pulled, so that the plug-in slot 11 and the plug-in rod 12 opened in the fixed block 10 installed on the arc plate 7 are under the action of the extrusion force (because the inner wall of the plug-in slot 11 close to the frame 1 is inclined, so when the arc plate 7 is pulled, the plug-in rod 12 close to the frame 1 contacts the inclined surface of the plug-in slot 11, so the plug-in rod 12 can be subjected to the extrusion force). At this time, the plug-in rod 12 slowly moves backwards with the assistance of the sliding mechanism until the plug-in rod 12 and the plug-in slot 11 are separated. At this time, the frame 1 can be disassembled, so it is more convenient to a certain extent than the bolt installation.
