[0030] 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.

[0031] Reference Figures 1 to 3 This utility model provides an embodiment of a quick-assembly and disassembly edge protection railing structure, including a railing frame 1 with a railing 2 fixedly connected inside. The railing 2 is made of high-strength steel, which can effectively withstand the impact force when construction personnel lean on it, ensuring safety. A support plate 4 is fixedly connected to the lower end of the railing frame 1. The thickness of the support plate 4 is calculated mechanically to stably support the weight of the railing frame 1 and transfer the load to the structure below. A support shell 5 is slidably connected inside the support plate 4. The sliding fit between the support shell 5 and the support plate 4 has high precision, ensuring smooth movement and alignment during installation.

[0032] A rotating groove 11 is provided on the outer side of the housing 5. The rotating groove 11 is designed in a spiral shape to facilitate the fixing ring 12 to rotate along its trajectory for fixation. The outer side of the rotating groove 11 is threaded with the fixing ring 12. The thread of the fixing ring 12 is tightly engaged with the thread of the rotating groove 11 to ensure that it will not loosen due to vibration or other factors after fixation.

[0033] The fixed ring 12 is connected to rotating shafts 13 on all four sides. The rotating shafts 13 can rotate flexibly, making it convenient for construction personnel to rotate the fixed ring 12. The bottom of the fixed ring 12 is slidably connected to the top of the receiving plate 4. The contact surfaces of the two are polished to reduce friction during rotation. The bottom of the spring 8 is fixedly connected to the inside of the receiving shell 5. The spring 8 has good elastic restoring ability and can provide upward thrust after the pressing column 6 is pressed down. The pressing column 6 is slidably connected inside the receiving shell 5. The sliding gap between the pressing column 6 and the receiving shell 5 is controlled within a reasonable range to ensure smooth and non-jamming action when pressing. The top of the pressing column 6 is fixedly connected to the button 7. The surface of the button 7 is provided with anti-slip texture to facilitate the pressing operation of construction personnel. The outer side of the button 7 is slidably connected to the inside of the receiving shell 5. The receiving shell 5 plays a guiding and limiting role in the sliding of the button 7.

[0034] A cover 14 is fixedly connected to the outer side of the receiving shell 5. The cover 14 can prevent dust and debris from entering the interior of the receiving shell 5 and affecting the normal operation of the internal components. Springs 2 9 are fixedly connected to both sides of the pressing column 6. When not under force, the springs 2 9 are in a naturally extended state and can provide outward elastic force to the spring rod 10. The other end of the two springs 2 9 is fixedly connected to the spring rod 10. The spring rod 10 can lock the receiving plate 4 under the action of the springs 2 9 to fix the railing frame 1. The pressing column 6 is rotatably connected to the right side of the spring rod 10. The rotatable connection allows the spring rod 10 to rotate relative to the pressing column 6 to adapt to different working states. Spring 1 8 is fixedly connected to the lower end of the pressing column 6. The upper end of spring 1 8 is tightly connected to the pressing column 6 to ensure stable force transmission. A connecting assembly is fixedly connected to the outer side of the railing frame 1. The connecting assembly is used to realize the quick connection and disassembly between the two railing frames 1.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The connecting component includes a receiving shaft 15, the inner side of which is fixedly connected to the outer side of the railing frame 1. The length of the receiving shaft 15 is reasonably designed so that the connecting groove 16 can be correctly connected to the connecting component of another railing frame 1. The end of the receiving shaft 15 away from the railing frame 1 is fixedly connected to the connecting groove 16. The internal space of the connecting groove 16 is of moderate size and can accommodate components such as the buckle 17 to move within it. The end of the connecting groove 16 away from the receiving shaft 15 is fixedly connected to the connecting groove 3. The connecting groove 3 communicates with the connecting groove 16, providing a channel for the movement of components such as the buckle 17. A card 21 is slidably connected inside the connecting groove 3. The card 21 can slide within the connecting groove 3 to achieve locking and releasing of the buckle 17.

[0036] The top of the card 21 is fixedly connected to a fixing ring 23, which is used to fix the spring 3 22 to prevent it from shifting during operation. The outer side of the card 21 is fitted with the spring 3 22. The spring 3 22 will compress and store force when the buckle 1 17 is pressed. When the external force disappears, it releases the elastic force to push the buckle 1 17 to move. The bottom of the card 21 is slidably connected to the buckle 1 17. The buckle 1 17 can slide along the bottom of the card 21 to achieve engagement and disengagement with the card 21. The outer side of the buckle 1 17 is slidably connected to the buckle 2 18. The sliding cooperation between the buckle 2 18 and the buckle 1 17 allows the two to move together.

[0037] A third buckle 19 is fixedly connected to the right side of buckle 2 18. Buckle 3 19 is fixedly connected to buckle 2 18 and participates in the connection and disassembly process. Buckle 1 17 is slidably connected inside buckle 3 19. Buckle 1 17 can slide inside buckle 3 19 to adjust its position. The outer side of buckle 1 17 is slidably connected to the bottom of card 21 to ensure that buckle 1 17 will not detach when sliding at the bottom of card 21. A connecting shaft 20 is fixedly connected to the right side of buckle 1 17. The connecting shaft 20 is used to connect buckle 1 17 to the corresponding component of another railing frame 1 to realize the linkage between the two.

[0038] Working Principle: A quick-assembly and disassembly edge protection fence structure. The connecting device in the middle is activated by pressing the left side of one fence frame 1 and the right side of another fence frame 1. When pressed, buckle 17 moves into the connecting groove 26, and is locked in place by card 21 by spring 32, thus completing the connection between the two fences. When pressed again, spring 322 causes buckles 28 and 39 to slide into the left side of card 21, and buckle 17 moves to the far left of connecting groove 26. Then, the mechanism is released, and buckles 17, 28, and 39 slide together out of card 21 through the structure of buckle 319, finally leaving connecting groove 3, completing the disassembly of the two fences.

[0039] Pressing button 7 causes the pressing column 6 to press down on spring 8, bringing spring rod 10, which is rotatably connected to the pressing column 6, to the appropriate position. Spring 9 then activates, causing spring rod 10 to spring open and lock onto the receiving plate 4. The rotating shaft 13 then uses the fixing ring 12 to pass through the rotating groove 11 to the top of the receiving plate 4 for fixation. For disassembly, first rotate the rotating shaft 13 to return fixing ring 12 to the top of the receiving housing 5 through the rotating groove 11. Then press button 7 again to cause the pressing column 6 to press down on spring 8. At this time, spring 8 is in a compressed state, causing spring rod 10 to retract inwards into the receiving housing 5 due to the action of the receiving housing 5. Then, remove the spring rod from the receiving housing.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
