Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a movable campus traffic guardrail. Background Art

[0002] Traffic guardrails are a type of traffic safety facility installed on both sides of the road or on the central dividing strip to protect the safety of pedestrians and vehicles and prevent vehicles from running off the road or entering the opposite lane. Traffic guardrails are usually made of steel, iron, aluminum alloy and other materials. They have certain impact resistance and buffering properties, can absorb collision energy, and reduce damage to occupants. They are widely used. Wherever there is a certain amount of traffic flow on the road, traffic guardrails can be installed according to usage needs. This patent is for traffic guardrails on campus.

[0003] After searching, the patent document with publication number CN107905151A discloses a traffic guardrail, including a first telescopic rod, a second telescopic rod and a first railing.

[0005] The existing campus traffic guardrails do not have good mobility when in use. In actual use, campus guardrails are often installed according to actual needs. When the needs change, the protection position of the guardrail often needs to be changed. This requires the guardrail to have convenient movement measures to move. At the same time, after the movement is completed, it must still have stability to ensure that the guardrail itself is fully utilized. At the same time, when the guardrail is in use, it basically does not appear alone, and it protects a section of road. This requires connection measures between the guardrails to improve the overall protection performance. Utility Model Content

The plurality of guide rods 12 are all slidably connected to the inner top surface of the base 6, and the bottom ends of the plurality of guide rods 12 are fixedly connected to a support plate 13, and the bottom surface of the support plate 13 is provided with four universal wheels 14. A No. 1 support partition is fixedly connected to the inner wall of the hollow connecting column 3, and a No. 1 rotating shaft 5 is rotatably connected to the side wall of the No. 1 support partition, and a plurality of No. 2 supporting partitions are fixedly provided in the No. 1 support column 1 and the No. 2 support column 2, and two No. 2 rotating shafts 9 are respectively rotatably connected to the surfaces of the plurality of No. 2 supporting partitions, and the No. 1 supporting partition and the No. 2 supporting partition are used to improve the running stability of the No. 1 rotating shaft 5 and the No. 2 rotating shaft 9, and sufficient support is provided. A turntable 22 is circumferentially fixedly connected to one end of the No. 1 rotating shaft 5 near the functional column 16, and a plurality of rotating rods are equidistantly fixedly connected to the circumferential side wall of the turntable 22, which is convenient for the staff to operate;

[0027] A connecting assembly is arranged at both ends of the No. 1 rotating shaft 5. The connecting assembly includes a sleeve 15 and a functional column 16 fixedly connected to both ends of the No. 1 rotating shaft 5. A plurality of connecting grooves 17 are arranged on the circumferential surface of the sleeve 15. A plurality of T-shaped grooves 18 are arranged in the functional column 16. T-shaped sliders 19 are slidably connected in the plurality of T-shaped grooves 18. The side walls of the plurality of T-shaped sliders 19 are fixedly connected with a mounting column 20. A plurality of connecting rods 21 are arranged in the circumference of the mounting column 20. The plurality of connecting grooves 17, T-shaped grooves 18, T-shaped sliders 19 and connecting rods 21 are the same in number and cooperate with each other so that the connecting assembly can operate normally. At the same time, the T-shaped grooves 18 and the T-shaped sliders 19 enable the functional column 16 and the mounting column 20 to have the ability to rotate relative to each other, and can also be tightly connected together.

[0028] The detailed working process of the utility model is as follows:

[0029] Before use, when it is necessary to connect two adjacent guardrails, place them in a straight line so that the adjacent mounting post 20 is aligned with the sleeve 15 of the other guardrail, and then continue to move closer and insert the mounting post 20 into the sleeve 15. If the position of the connecting rod 21 does not correspond to the position of the connecting slot 17 at this time, it can be adjusted directly by rotating the mounting post 20 or by slightly rotating the No. 1 rotating shaft 5 through the turntable 22. When the position of the connecting rod 21 corresponds to the connecting slot 17, the two guardrails are brought closer, and the mounting post 20 is gradually inserted into the sleeve 15. When it is fully inserted, since the connecting slot 17 is a multi-segment slot, after it is fully inserted, the mounting post 20 is slightly rotated and pulled out a section. At this time, the installation is achieved through the clamping effect of the connecting rod 21 and the connecting slot 17 bracket, so that the mounting post 20 and the sleeve 15 are more stably connected, thereby realizing the connection between the two adjacent guardrails;

[0030] After the connection between the guardrails on the road section is completed, if it is necessary to move them, the No. 1 rotating shaft 5 is rotated by the turntable 22, and the No. 1 rotating shaft 5 rotates, driving the No. 1 bevel gear 7 to rotate, and the meshing transmission between the bevel gear sets makes the No. 2 bevel gear 10 also rotate, thereby driving the No. 2 rotating shaft 9 and the threaded rod 8 to rotate. When the threaded rod 8 rotates, the nut 11 will not rotate under the restriction of multiple guide rods 12, and then move up and down along the threaded rod 8, and drive the support plate to move through the guide rod 12. When it needs to move, let the support plate 13 move downward so that the four universal wheels 14 contact the bottom surface and support, and the base 6 Leaving the bottom surface, the guardrail has a mobile function. At the same time, when the guardrails are connected together, the No. 1 rotating shaft 5 rotates, which will drive the sleeve to rotate, and then under the restriction of the connecting groove 17 and the connecting rod 21, the mounting column 20 of the adjacent guardrail and the No. 1 rotating shaft 5 are driven to rotate, which also makes the moving components of the adjacent guardrail work and is more convenient to move. In this way, the connecting section cannot be too long. The longer the section, the greater the force required. At the same time, the rigidity requirement of the material is also higher. However, it can basically meet the use needs on campus. After completing the movement, the moving component is folded up and the base 6 contacts the bottom surface again, so that the guardrail still has good stability and protection.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
