[0032] 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.

[0033] Please see Figure 1-11 In this embodiment of the present invention, a foldable portable guardrail includes a base rod 1, a top rod 2 above the base rod 1, and a plurality of rotating rods 3 evenly arranged between the top rod 2 and the base rod 1. One end of each of the plurality of rotating rods 3 is rotatably connected to a plurality of limiting connecting seats 4. The ends of two of the rotating rods 3 located at the end of the top rod 2 that are away from the limiting connecting seats 4 are rotatably connected to two positioning connecting seats 6, and the ends of the remaining plurality of rotating rods 3 that are away from the connecting seats 4 are rotatably connected to a plurality of connecting seats 5. The sides of the plurality of connecting seats 4 that are away from the rotating rods 3 are all fixedly connected to the base rod 1. The sides of the plurality of connecting seats 5 and the two positioning connecting seats 6 that are away from the rotating rods 3 are all fixedly connected to the top rod 2 4.

[0034] Both of the positioning connecting seats 6 are movably connected to the inner side of the two positioning connecting seats 6; both of the rotating rods 3 that are rotatably connected to the positioning connecting seats 6 are fixedly connected to the outer side of the end near the positioning connecting seat 6 with positioning components 8; and the bottom rod 1 is evenly fixedly connected to a pair of ball-shaped buckle components 9 near the buckling components 7.

[0035] The snap-fit ​​assembly 7 includes a movable block 71, with a snap-fit ​​post 72 fixedly connected to the bottom center of the movable block 71; multiple limiting rods 73 are symmetrically fixedly connected to the top of the movable block 71, and springs 74 are provided on the outer side of each of the multiple limiting rods 73, with one end of each spring 74 fitting against the top of the movable block 71 and the other end fitting against the top rod 2; the positioning assembly 8 includes a fixing member 81, with one end of the fixing member 81 fixedly connected to the rotating rod 3 and the other end having a positioning hole 82 penetrating through the fixing member 81, and the diameter of the positioning hole 82 being larger than the diameter of the snap-fit ​​post 72;

[0036] Each of the multiple limiting connecting seats 4 has a protruding plate on the side away from the movable block 71 to limit the range of motion of the rotating rod 3; the top rod 2 has multiple threaded holes for installing external accessories evenly distributed on the side away from the positioning connecting seat 6; the top rod 2 has a round hole for the limiting rod 73 to pass through at the position corresponding to the multiple limiting rods 73; the bottom rod 1 has a round hole for the locking post 72 to pass through at the position corresponding to the two spherical buckle assemblies 9.

[0037] The positioning connection seat 6 includes a seat body 61, which is T-shaped. The top end of the seat body 61 is rotatably connected to the rotating rod 3, and the inner side of the other end and the inner side of the lower end are provided with through grooves for accommodating the movable block 71. Both sides of the seat body 61 are provided with vertically arranged movable grooves 62.

[0038] By adopting the above technical solution, during the unfolding of the guardrail, the movable block 71 moves and rotates with the rotating rod 3 and approaches the fixing member 81. The end of the fixing member 81 away from the rotating rod 3 has an inclined surface. After the movable block 71 approaches the fixing member 81, the locking pin 72 can move upward along the inclined surface of the fixing member 81, thereby raising the movable block 71 as a whole and compressing multiple springs 74 until the locking pin 72 moves to the position of the positioning hole 82. At this time, the rotating rod 3 is in a vertical state, and the unfolding of the guardrail is completed. The elastic force generated by the multiple springs 74 can make the movable block 71 descend and reset, and the locking pin 72 falls into the positioning hole 82. The fixing member 81 can restrict the movable block 71 and prevent the movable block 71 from moving, thereby locking the rotating rod 3 and the top rod 2 to prevent the rotating rod 3 from rotating and displacing. The protrusions of the multiple limiting connecting seats 4 can further increase the stability of the rotating rod 3. Together with the fixing member 81, the rotating rod 3 is fixed from two directions, which can prevent the rotating rod 3 from rotating and displacing excessively when unfolding, and can also prevent the rotating rod 3 from resetting arbitrarily after unfolding.

[0039] In this embodiment, the movable block 71 is L-shaped and located in the through groove of the base 61; movable columns 76 are fixedly connected to both sides of the movable block 71, and the ends of the two movable columns 76 away from the movable block 71 are respectively located in the two movable slots 62; an auxiliary plate 75 is integrally provided on the inner side of the movable block 71, and the auxiliary plate 75 is located on the outer side of the base 61; arc-shaped slots 77 are provided on both sides of the middle section of the locking column 72.

[0040] The spherical buckle assembly 9 includes two spherical buckles 93, with a space between the two spherical buckles 93 for the pin 72 to pass through, and the curvature of the two slots 77 is the same as the curvature of the spherical buckles 93.

[0041] The two spherical buckles 93 are fixedly connected to the opposite sides of each other, and the inner sides of the two limiting cylinders 94 are provided with springs 95.

[0042] Both of the two spherical buckles 93 are coaxially and movably connected to sleeves 91 on their outer sides. The top of the outer side of the two sleeves 91 away from the spherical buckles 93 is integrally provided with a connecting plate 92. Both connecting plates 92 are fixedly connected to the bottom rod 1. One end of the spring 95 is fixedly connected to the spherical buckle 93, and the other end is fixedly connected to the inner wall of the sleeve 91.

[0043] By adopting the above technical solution, when the guardrail needs to be folded, the worker places their hand on the inside of the end of the movable block 71 away from the locking post 72, and then manually lifts the movable block 71, raising the locking post 72 above the positioning hole 82; the worker controls the rotating rod 3 to rotate back to its original position, while the bottom rod 1 and the top rod 2 move closer to each other; until the locking post 72 rotates and moves to the position of the two spherical buckles 93, the bottom of the locking post 72 is hemispherical, and the diameter of the locking post 72 is greater than the initial distance between the two spherical buckles 93; under the pushing of the locking post 72, the two spherical buckles 93 move away from each other and press the spring 95 that is fixedly connected to them, until the slots 77 on both sides of the locking post 72 move to the position of the spherical buckles 93. At this time, the elastic force generated by the spring 95 can push the spherical buckles 93 into the slots 77, so that the two spherical buckles 93 cooperate to clamp and fix the locking post 72, so that the folded guardrail will not unfold at will, making it convenient to carry and move.

[0044] The working principle of this utility model is as follows: During the unfolding of the guardrail, the movable block 71 moves and rotates with the rotating rod 3 and approaches the fixing member 81. The end of the fixing member 81 away from the rotating rod 3 has an inclined surface. After the movable block 71 approaches the fixing member 81, the locking post 72 can move upward along the inclined surface of the fixing member 81, thereby raising the movable block 71 as a whole and compressing multiple springs 74 until the locking post 72 moves to the position of the positioning hole 82. At this time, the rotating rod 3 is in a vertical state, and the unfolding of the guardrail is completed. The elastic force generated by the multiple springs 74 can make the movable block 71 descend and reset, and the locking post 72 falls into the positioning hole 82. The fixing member 81 can restrict the movable block 71 and prevent the movable block 71 from moving, thereby locking the rotating rod 3 and the top rod 2 and preventing the rotating rod 3 from rotating and displacing. The protrusions of the multiple limiting connecting seats 4 can further increase the stability of the rotating rod 3. Together with the fixing member 81, the rotating rod 3 is fixed from two directions, which can prevent the rotating rod 3 from rotating and displacing excessively when unfolding, and can also prevent the rotating rod 3 from resetting arbitrarily after unfolding.

[0045] When the guardrail needs to be folded, the worker places their hand on the inside of the movable block 71 away from the locking post 72, and then manually lifts the movable block 71, raising the locking post 72 above the positioning hole 82. The worker controls the rotating rod 3 to rotate back to its original position, while the bottom rod 1 and the top rod 2 move closer to each other. This continues until the locking post 72 rotates and moves to the position of the two spherical buckles 93. The bottom of the locking post 72 is hemispherical, and the diameter of the locking post 72 is larger than the initial distance between the two spherical buckles 93. Under the pushing action of the locking post 72, the two spherical buckles 93 move away from each other and press against the spring 95 that is fixedly connected to them, until the slots 77 on both sides of the locking post 72 move to the position of the spherical buckles 93. At this time, the elastic force generated by the spring 95 can push the spherical buckles 93 into the slots 77, so that the two spherical buckles 93 cooperate to clamp and fix the locking post 72, preventing the folded guardrail from unfolding at will and making it easy to carry and move.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
