[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this embodiment can be combined with each other. The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 6 As shown, the purpose of this embodiment is to be able to adjust according to the width of the road surface and cannot be conveniently stored. In view of this, a foldable roadblock structure is provided, including two support rods 1 and two opposing inclined rods 2 arranged on the two support rods 1: the tops of the two groups of opposing inclined rods 2 are provided with fixed rings 3, and a telescopic roadblock structure 5 is rotatably installed between the left and right fixed rings 3. Two telescopic roadblock structures 5 are symmetrically arranged up and down, and two independent blocking mechanisms 6 are rotatably installed on the telescopic roadblock structure 5. The blocking mechanism 6 is used to provide rigid support for the upper and lower telescopic roadblock structures 5. At the same time, the arrangement of multiple blocking mechanisms 6 can also achieve a blocking effect. Both ends of the telescopic roadblock structure 5 are smooth ends, and the smooth ends at both ends of the telescopic roadblock structure 5 are rotatably installed in the fixed ring 3.

[0032] In order to be able to adjust at will according to the width of the road surface and to be able to be conveniently stored, the telescopic roadblock structure 5 includes a blocking rod A501, on which a thread 7 is provided and a blocking rod B accommodating groove 5011 is opened in the blocking rod A501, and the blocking rod B accommodating groove 5011 is used to store and hide the blocking rod B502 in the blocking rod A501, and a fixed ring limiting groove A5012 is opened on the outer side of the other end of the blocking rod A501, which can be limited when the telescopic roadblock structure 5 is used, and the thread can be threadedly moved to adjust the size of the blocking rod A501 to adapt to different road surface widths.

[0033] In order to be able to adjust freely according to the width of the road surface and to be able to store it conveniently, one end of the blocking rod A501 is rotatably installed in the fixed ring 3 on the left side, and the other end of the blocking rod A501 is threadedly installed with a blocking rod B502. A blocking rod C accommodating groove 5023 is provided inside the blocking rod B502, and a thread 7 is provided on the blocking rod B502. A limiting ring B5021 is fixedly provided on the outer wall of one end of the blocking rod B502. The limiting ring B5021 is used for limiting the position of the foldable roadblock structure when in use, and a fixed ring limiting groove B5022 is provided on the outer wall of the other end of the blocking rod B502.

[0034] Among them, a blocking rod C503 is threadedly installed on one end of the blocking rod B502, a limiting ring C5031 is fixedly installed on one end of the blocking rod C503, and the other end of the top blocking rod C503 is rotatably installed in the fixed ring 3 on the right. When folding and storing, the blocking rod B502 is rotated to rotate the blocking rod B502 in the direction of the blocking rod A501, and the blocking rod B502 is folded and stored in the blocking rod A501.

[0035] Further, the blocking mechanism 6 includes a blocking rod 603, one end of which is fixedly mounted with a fixing ring B602, and the other end of which is fixedly mounted with a fixing ring A601. One of the blocking mechanisms 6 fixes and supports the upper and lower blocking rods A501, and the fixing ring B602 is rotatably mounted in the fixing ring limiting groove A5012 of the upper blocking rod A501, and the fixing ring A601 is rotatably mounted in the fixing ring limiting groove A5012 of the lower blocking rod A501. When the upper and lower blocking rods A501 rotate, it is ensured that the blocking mechanism 6 does not rotate together. Similarly, the other blocking mechanism 6 fixes and supports the upper and lower blocking rods B502.

[0036] Furthermore, a rotating shaft 4 is fixedly mounted on the side wall of the support rod 1 , wherein both ends of the telescopic roadblock structure 5 at the bottom are rotatably connected to the rotating shaft 4 .

[0037] It should be supplemented that the ends of the blocking rod A501 and the blocking rod B502 are respectively provided with through holes for the blocking rod B502 and the blocking rod C503 to be inserted, and the diameters of the two through holes are respectively smaller than the diameters of the blocking rod B accommodating groove 5011 and the blocking rod C accommodating groove 5023, the diameter of the limiting ring B5021 is larger than the diameter of the through hole on the blocking rod A501 and smaller than the diameter of the blocking rod B accommodating groove 5011; the diameter of the limiting ring C5031 is larger than the diameter of the through hole of the blocking rod B502 and smaller than the diameter of the blocking rod C accommodating groove 5023.

[0038] When the utility model is used, the blocking rod B502 and the blocking rod C503 are rotated. Since the blocking rod B502 and the blocking rod C503 are respectively threadedly connected to the blocking rod A501 and the blocking rod B502, the two will move horizontally to extend or shorten during the rotation, so the length of the entire telescopic roadblock structure 5 can be adjusted to meet the use requirements of roads of different widths. When using the foldable roadblock structure, if the folded and stored roadblock cannot block, we can rotate the blocking rod B502, and the fixing ring B602 is rotatably installed in the fixing ring limit groove A5012 of the upper blocking rod A501, so the blocking mechanism 6 will not rotate when the blocking rod B502 is rotated. If the blocking rod B502 is completely turned out, it still cannot completely block. The blocking rod B502 is provided with a limit ring B5021, and the blocking rod A501 is provided with a blocking rod B receiving groove 5011 with a diameter larger than the limit ring B5021, which can limit the blocking rod B502 when in use. Similarly, the blocking rod C503 is provided with a limit ring C5031, and the blocking rod B502 is provided with a blocking rod C receiving groove 5023 with a diameter larger than the limit ring C5031, which can limit the blocking rod C503 when in use.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
