[0011] Preferably, rubber pads are fixedly connected to the outer walls of both side plates.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown, this utility model provides a technical solution, a connection structure for a stainless steel guardrail assembly, including a mounting plate 1. Two first rotating shafts 2 are symmetrically fixedly connected to the top of the mounting plate 1. Connecting brackets 3 are rotatably connected to the outer walls of the two first rotating shafts 2. A fixing bracket 4 is fixedly connected to one end of each of the two connecting brackets 3. A slot 5 is provided on the inner wall of the fixing bracket 4. Two locking blocks 6 are symmetrically slidably connected to the inner wall of the fixing bracket 4. One end of the locking block 6 is set as an inclined surface and extends into the interior of the slot 5. A first spring 7 is fixedly connected to the other end of the locking block 6. The first spring 7 is fixedly connected to the fixing bracket 4. An unlocking unit is provided inside the fixing bracket 4.

[0024] With the above technical solution, when splicing two fence panels, the fence panel is inserted into the slot 5. As the fence panel is inserted, it pushes the inclined surface of the outer wall of the two locking blocks 6 when they are pressed against the two locking blocks 6, so that the two locking blocks 6 move simultaneously and press against the first spring 7. After the fence panel is fully inserted into the slot 5, the squeezing of the fence panel is removed. Under the action of the first spring 7, the two locking blocks 6 are reset simultaneously. The fence panel is fixed in the fixing frame 4 by the two locking blocks 6, thus completing the splicing of the two fence panels. The position of the fence panel can be easily adjusted by rotating the first rotating shaft 2 and the connecting frame 3. When separating the two fence panels, the two locking blocks 6 are moved by the unlocking unit. After the two locking blocks 6 are removed, the fence panel can be easily taken out from the slot 5.

[0025] Specifically, the unlocking unit includes a second rotating shaft 8, which is located inside the fixed frame 4 and rotatably connected to the fixed frame 4. A gear 9 is fixedly connected to the outer wall of the second rotating shaft 8. Two racks 10 are symmetrically slidably connected to the inner wall of the fixed frame 4 with the second rotating shaft 8 as the center. Both racks 10 are meshed with the gear 9. A connecting plate 11 is fixedly connected to one end of each rack 10. Both connecting plates 11 are slidably connected to the fixed frame 4. The two connecting plates 11 are fixedly connected to two locking blocks 6 respectively. A knob 12 is fixedly connected to the top of the second rotating shaft 8 through the fixed frame 4.

[0026] With the above technical solution, when separating the two fence panels, rotating the knob 12 drives the second rotating shaft 8 to rotate, causing the gear 9 to rotate, which in turn drives the two racks 10 to move away from each other, causing the two connecting plates 11 to move away from each other, thereby causing the two locking blocks 6 to open up to each other.

[0027] Specifically, two limiting plates 25 are symmetrically fixedly connected to the top of the mounting plate 1.

[0028] Through the above technical solution, the rotation angle of the two connecting frames 3 can be limited by the setting limit plate 25, thereby limiting the rotation angle of the two fence panels.

[0029] Specifically, the outer walls of the two connecting frames 3 are each fixedly connected with several limiting teeth 19 at equal intervals. The inner wall of the mounting plate 1 is symmetrically slidably connected with two sliding shafts 20. The top of each sliding shaft 20 is fixedly connected with a top plate 21. The top of each top plate 21 is fixedly connected with limiting teeth 22. The limiting teeth 22 are used in conjunction with the limiting teeth 19. The bottom of each sliding shaft 20 is fixedly connected with a limiting block 24. The outer wall of the sliding shaft 20 is fitted with a third spring 23. The top of the third spring 23 is fixedly connected to the top plate 21, and the bottom of the third spring 23 is fixedly connected to the mounting plate 1.

[0030] Through the above technical solution, the third spring 23 is set to allow the limiting tooth 22 to be inserted between two adjacent limiting teeth 19. The limiting tooth 22 fixes the position of the limiting teeth 19, preventing the connecting frame 3 from rotating arbitrarily on the mounting plate 1, thereby improving the overall stability of the guardrail. When it is necessary to adjust the shape of the guardrail, press the limiting tooth 22 down to drive the top plate 21 to move downward and press the third spring 23. After the limiting tooth 22 moves downward, it separates from the limiting teeth 19, which makes it easier to rotate the connecting frame 3 on the first rotating shaft 2. After the shape of the guardrail is adjusted, the limiting tooth 22 is released, and the limiting tooth 22 fixes the angle of the connecting frame 3 again.

[0031] Specifically, a damping rod 13 is fixedly connected to the inner wall of slot 5. Two sliders 14 are symmetrically slidably connected to the outer wall of the damping rod 13. A connecting shaft 15 is rotatably connected to the outer wall of each slider 14. A side plate 17 is rotatably connected to one end of each connecting shaft 15. Two second springs 16 are symmetrically sleeved on the outer wall of the damping rod 13. One end of the second spring 16 is fixedly connected to the fixing frame 4, and the other end of the second spring 16 is fixedly connected to the slider 14.

[0032] With the above technical solution, when the fence panel is inserted into the slot 5, it pushes the side plate 17 to move, causing the two connecting shafts 15 to rotate simultaneously, so that the two sliders 14 slide on the damping rod 13 at the same time, pressing the two second springs 16. After the fence panel is fully inserted into the slot 5, the two second springs 16 make the side plate 17 press against the fence panel, preventing the fence panel from shaking in the slot 5.

[0033] Specifically, rubber pads 18 are fixedly connected to the outer walls of both side panels 17.

[0034] Through the above technical solution, the rubber pad 18 allows the side plate 17 to fit better against the fence panel and protect the fence panel. When the fence panel is hit, it avoids rigid collision between the fence panel and the fixing frame 4, thereby improving the firmness of the fence panel after splicing.

[0035] In use, when splicing two fence panels, the fence panel is inserted into the slot 5. As the fence panel is inserted, it presses against the two locking blocks 6, pushing the inclined surfaces of the outer walls of the two locking blocks 6, causing the two locking blocks 6 to move simultaneously and press against the first spring 7. After the fence panel is fully inserted into the slot 5, the pressure of the fence panel is released, and under the action of the first spring 7, the two locking blocks 6 return to their original positions. The two locking blocks 6 fix the fence panel in the fixing frame 4, thus completing the splicing of the two fence panels. When the fence panel is inserted into the slot 5, it pushes the side plate 17 to move. This causes the two connecting shafts 15 to rotate simultaneously, causing the two sliders 14 to slide simultaneously on the damping rod 13, pressing the two second springs 16. After the fence panel is fully inserted into the slot 5, the two second springs 16 press the side plate 17 against the fence panel, preventing the fence panel from shaking in the slot 5. The rubber pad 18 allows the side plate 17 to better fit the fence panel and protects it. In the event of an impact, it prevents the fence panel from rigidly colliding with the fixing frame 4, thus improving the firmness of the fence panel after splicing. The third spring... 23. The limiting tooth 22 is inserted between two adjacent limiting teeth 19. The limiting tooth 22 fixes the position of the limiting teeth 19, preventing the connecting frame 3 from rotating freely on the mounting plate 1, thereby improving the overall stability of the guardrail. When the shape of the guardrail needs to be adjusted, the limiting tooth 22 is pressed down, causing the top plate 21 to move downward and compressing the third spring 23. After the limiting tooth 22 moves downward, it separates from the limiting teeth 19, thus facilitating the rotation of the connecting frame 3 on the first rotating shaft 2, through the set limiting plate 25. This can limit the rotation angle of the two connecting frames 3, and thus limit the rotation angle of the two fence panels. After adjusting the shape of the guardrail, release the limiting tooth 22, so that the limiting tooth 22 fixes the angle of the connecting frame 3 again. When separating the two fence panels, turn the knob 12 to drive the second rotating shaft 8 to rotate, so that the gear 9 rotates and drives the two racks 10 to move away from each other, so that the two connecting plates 11 move away from each other. This causes the two locking blocks 6 to open up to each other. After the limiting of the two locking blocks 6 is lost, the fence panel can be easily removed from the slot 5.
