DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.
[0021] Embodiments of the present patent will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present patent and should not be construed as a limitation of the present patent.
[0022] In the description of the present patent, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings. These are only for the convenience of describing the present patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present patent.
[0023] In the description of the present patent, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "attachment", "setting" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present patent can be understood according to specific circumstances.
[0024] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a highway guardrail near a sidewalk includes a first column 1 and a second column 7. The first column 1 is higher than the second column 7. Upper crossbars 10 and lower crossbars 11 are fixedly connected to one side of both the first column 1 and the second column 7. Railings 13 are fixedly connected to the bottom outer wall of the upper crossbar 10 and the top outer wall of the lower crossbar 11. The height of the railing 13 gradually decreases along the direction approaching the second column 7. Since the height of the railing 13 in the guardrail gradually decreases along the direction approaching the second column 7, the height of the entire guardrail can be gradually decreased, making the driver's vision in the oncoming vehicles more open and reducing the incidence of traffic accidents at the sidewalk.
[0025] Preferably, bending portions are provided at one end of both the upper crossbar 10 and the lower crossbar 11, and the bending portions are fixedly connected to the second column 7. Bending portions are provided at one end of both the upper crossbar 10 and the lower crossbar 11 in the guardrail, making the end of the entire guardrail in a bent shape, which can cause the driver to actively avoid when approaching the sidewalk, achieving secondary protection for passing pedestrians.
[0026] Preferably, mounting seats 14 are inserted at the tops of the first upright column 1 and the second upright column 7. A reflector 3 is fixedly connected to the top of the mounting seat 14. A reflective strip 12 is provided on one outer wall of the railing 13. The vertical height of the reflective strip 12 gradually decreases in the direction close to the second upright column 7, which can play a good reflective warning role at night and further improve the safety of the entire guardrail.
[0027] Preferably, slots 2 are formed on both sides of the first upright column 1 and on one side of the second upright column 7. Both ends of the upper cross bar 10 and the lower cross bar 11 are inserted into the interior of the slots 2.
[0028] Preferably, round holes 15 are formed at both ends of the upper cross bar 10 and the lower cross bar 11. Through holes 5 are formed on both sides of the first upright column 1 and the second upright column 7. A fixing screw 4 is inserted into the through hole 5. Both ends of the fixing screw 4 pass through the interior of the round hole 15. Fixing nuts 6 are threadedly connected to both ends of the fixing screw 4. One side of the fixing nut 6 abuts against the outer wall of one side of the first upright column 1 or the second upright column 7. Through the combined action of the fixing screw 4 and the fixing nut 6, the upper cross bar 10 and the lower cross bar 11 can be firmly connected to the first upright column 1 and the second upright column 7.
[0029] Preferably, limiting ring plates 16 are fixedly connected to both ends of the upper cross bar 10 and the lower cross bar 11. One side of the limiting ring plate 16 abuts against the outer wall of one side of the first upright column 1 or the second upright column 7, which can play a limiting role during the process of inserting both ends of the upper cross bar 10 and the lower cross bar 11 into the interior of the slot 2, ensuring that the centers of the round hole 15 and the through hole 5 are the same and facilitating the subsequent insertion of the fixing screw 4.
[0030] Preferably, bases 9 are provided at the bottoms of the first upright column 1 and the second upright column 7. A mating groove 8 is formed at the top of the base 9. The first upright column 1 and the second upright column 7 are both engaged with the mating groove 8. Through the base 9, the stability of the bottom of the entire guardrail can be effectively ensured.
[0031] Working principle: Since the height of the railing 13 in the guardrail gradually decreases in the direction close to the second upright column 7, the height of the entire guardrail can be gradually reduced, making the driver's vision in the oncoming vehicle more open, reducing the incidence of traffic accidents at the sidewalk, and at the same time, one end of each of the upper cross bar 10 and the lower cross bar 11 in the guardrail is provided with a bent portion, making the end of the entire guardrail bent, which can cause the driver to actively avoid when approaching the sidewalk, realizing secondary protection for passing pedestrians. At the same time, a reflective strip 12 is pasted on one side of the railing 13, and reflectors 3 are provided at the tops of both the first upright column 1 and the second upright column 7, which can play a good reflective warning role at night and further improve the safety of the entire guardrail.
[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
