DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions 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.

[0029] like Figure 1~Figure 5 As shown, this embodiment provides a highway traffic guardrail, including

[0030] A pair of side columns 1 and a pair of inner grooves 2, wherein the inner grooves 2 are provided on the upper and lower ends of the surface of the side columns 1;

[0031] A sound insulation and noise reduction component 4, which is arranged in the inner groove 2;

[0032] A support moving assembly 5, wherein the support moving assembly 5 is arranged at the bottom of the side column 1;

[0033] A buffer protection component 3 is arranged outside the side column 1. The buffer protection component 3 includes a pair of outer grooves 3-1. The outer grooves 3-1 are opened on both sides of the surface of the side column 1. A connecting piece 3-2 is rotatably connected inside the outer groove 3-1. One end of the connecting piece 3-2 is rotatably connected to a side guardrail 3-3 through a pin shaft. A through cavity 3-4 is opened inside the side guardrail 3-3. A pair of round rods 3-5 are movably set together between the side guardrails 3-3. A buffer spring 3-6 is set together outside the round rod 3-5. A connecting plate 3-7 is fixedly connected outside the round rod 3-5. A protective plate 3-8 is fixedly connected outside the connecting plate 3-7.

[0034] In the present embodiment, in order to achieve a buffering protection effect for pedestrians or vehicles, a buffering protection component 3 is designed. Connecting rods are rotatably connected to the pin shafts on both sides of the side column 1, and one end of the connecting rod is rotatably connected to the side guardrail 3-3. A through cavity 3-4 is opened in the side guardrail 3-3, and a round rod 3-5 is movably mounted between the two connecting pieces 3-2. The round rod 3-5 is located in the through cavity 3-4, and the through cavity 3-4 allows the round rod 3-5 to have a movable space. A spring is mounted on the round rod 3-5. When the side guardrail 3-3 is collided or squeezed, a contraction effect is formed between the round rod 3-5 and the side guardrail 3-3, and the buffer spring 3-6 is cooperated to buffer the collision force. At the same time, the connecting piece 3-2 is rotated to change the matching angle at the connection, and a connecting plate 3-7 is fixedly connected to the round rod 3-5. The outside of the connecting plate 3-7 is fixedly connected to a protective plate 3-8, and further protection is provided by the protective plate 3-8.

[0035] Furthermore, the sound insulation and noise reduction component 4 includes a pair of sound insulation boards 4-1, and a connecting piece 4-4 is rotatably connected between the sound insulation boards 4-1 through a pin shaft. A connecting sleeve 4-2 is provided on the side end surface of the sound insulation board 4-1, and an insertion rod 4-3 is inserted and connected to the side surface of the side column 1. One end of the insertion rod 4-3 is located in the inner groove 2, and the insertion rod 4-3 is inserted and connected to the connecting sleeve 4-2.

[0036] In this embodiment, in order to achieve the effect of reducing the noise of passing vehicles, a sound insulation and noise reduction component 4 is designed. Two foldable sound insulation panels 4-1 are connected through a connecting piece 4-4. The side end face of the sound insulation panel 4-1 is provided with a connecting sleeve 4-2. The side surface of the side column 1 is plugged and connected with an insertion rod 4-3. The insertion rod 4-3 can be inserted into the connecting sleeve 4-2, so that the sound insulation panel 4-1 is installed between the side columns 1 by a split connection, can be selectively installed and used, and is easy to disassemble.

[0037] Furthermore, the supporting moving assembly 5 includes a supporting leg 5-1, which is fixed at the bottom of the side column 1. A pair of moving wheels 5-2 are arranged at the bottom of the supporting leg 5-1. A through opening 5-3 is opened on the side surface of the supporting leg 5-1. A pair of vertical rods 5-4 are fixedly connected to the bottom of the side column 1. The external sliding sleeve of the vertical rods 5-4 is connected to a stabilizing frame 5-5. The side surface of the stabilizing frame 5-5 is provided with an internal threaded tube 5-6. The internal threaded tube 5-6 is located in the through opening. A locking frame 5-7 is screwed inside the internal threaded tube 5-6.

[0038] In this embodiment, in order to achieve a stable support and movable effect for the overall structure, a supporting moving component 5 is designed. A supporting leg 5-1 is arranged at the bottom of the side column 1, and two moving wheels 5-2 are installed at the bottom of the supporting leg 5-1. The moving wheels 5-2 are supported on the ground and can be moved at will. Two vertical rods 5-4 are arranged on the bottom surface of the column on one side of the supporting leg 5-1, and a stabilizing frame 5-5 is vertically slidably connected to the outside of the vertical rod 5-4. The stabilizing frame 5-5 can move downward and be supported on the ground. A through hole 5-3 is opened on the side surface of the supporting leg 5-1, and an internal threaded tube 5-6 is arranged on the side surface of the stabilizing frame 5-5. The internal threaded tube 5-6 is in the through hole 5-3 and can slide vertically with the stabilizing frame 5-5. A locking frame 5-7 is screwed and connected in the internal threaded tube 5-6 through the through hole 5-3, so as to fix the locking frame 5-7 to the supporting leg 5-1.

[0039] Furthermore, the stabilizing frame 5 - 5 is in an L-shaped structure as a whole.

[0040] In this embodiment, the contact area between the bottom of the stabilizing frame 5 - 5 and the ground is increased through the L-shaped structure, thereby improving the stabilizing effect.

[0041] Furthermore, one end of the side guardrail 3 - 3 is bent inward to form an arc-shaped transition structure.

[0042] In this embodiment, the protection range and safety of the side guardrail 3-3 are increased by means of the arc-shaped structure bent inwardly.

[0043] Furthermore, the protective plate 3-8 has an arc-shaped structure, and the protective plate 3-8 is made of soft plastic material.

[0044] In this embodiment, the damage caused by the protective plates 3-8 to people and vehicles is minimized through the arc-shaped plastic material structure.

[0045] When it is needed, move it to the protective position via the moving wheel 5-2, loosen the locking frame 5-7 at the bottom, slide the stabilizing frame 5-5 downward on the vertical rod 5-4 and fit it on the ground, then tighten the locking frame 5-7 to fix the stabilizing frame 5-5. When sound insulation and noise reduction are needed, unfold the sound insulation board 4-1 through the connecting piece 4-4, place it in the inner groove 2, insert the insertion rod 4-3 on the surface of the side column 1 and enter into the connecting sleeve 4-2 of the sound insulation board 4-1. During use, when a human body or a vehicle touches the protective plate 3-8, the protective plate 3-8 will first be slightly deformed, and then the side guardrail 3-3 will contract through the round rod 3-5 and the buffer spring 3-6 to buffer a certain impact force and reduce the degree of damage to the human body and the vehicle after contact.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
