Description

Technical Field

[0001] This utility model relates to the field of roadblock technology, and more specifically to a temporary roadblock. Background Technology

[0002] Temporary roadblocks are obstacles temporarily erected to ensure safety or control traffic flow during road construction, accident scenes, special events, or emergencies. These roadblocks can take various forms, such as water-filled barriers, traffic cones, and movable guardrails.

[0003] The existing invention patent publication (announcement) number CN109371808B, published (announcement) date 2024-06-21, discloses a movable temporary guide roadblock, including two support mechanisms connected by a connecting column. Each support mechanism includes a support rod, a control cylinder, and a support base column. One support mechanism has several evenly distributed gripping devices on its support base column, while the other support mechanism has several evenly distributed rotating cylinders on its support base column. An arc column is fixedly connected to the middle of the support rod. Through the design of the gripping devices and rotating cylinders, the roadblock can achieve two modes: one is that after being impacted, the roadblock falls onto the bottom surface to ensure that vehicles can pass over it smoothly, minimizing the impact on the vehicles; the other is that the roadblock is firmly fixed to the ground, serving to stop vehicles.

[0004] However, in the prior art, including the aforementioned patents, the roadblock is directly impacted by the vehicle, thus generating a reaction force on the vehicle, which can cause serious damage to the vehicle. Utility Model Content

[0005] The purpose of this invention is to provide a temporary roadblock to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temporary roadblock, comprising a left support rod and a right support rod that are hinged to each other, and the left support rod and the right support rod have staggered positions maintained at a predetermined angle during their movement;

[0007] Anti-collision plates are set opposite to each other and fixedly connected to the left and right support rods respectively, and the anti-collision plates bulge under staggered work positions;

[0008] An expansion baffle is rotatably mounted to limit the opening of the left and right struts, and the expansion baffle expands in staggered positions to cover the bottom of the left and right struts.

[0009] Preferably, the expansion baffle includes a foot plate and a flap fixedly mounted on the foot plate, and the expansion baffle, the foot plate, and the flap form an expansion cavity.

[0010] Preferably, the system also includes folding rods disposed on the left and right support rods, the folding rods comprising a left-hand rotating rod rotatably disposed on the right support rod and a right-hand rotating rod rotatably disposed on the left support rod.

[0011] Preferably, an extension rod is slidably provided on the left rotating rod, and a limiting member for inserting the extension rod is fixedly provided on the right rotating rod.

[0012] Preferably, it also includes an air chamber that forms a piston-like engagement with the extension rod.

[0013] Preferably, the expansion chamber is connected to the air chamber.

[0014] In the above technical solution, the temporary road barrier provided by this utility model has the following beneficial effects: when the left and right support rods are not in use, they are plate-shaped as a whole and can be stored in a narrow space. When the left and right support rods are unfolded, the upper and lower ends of the anti-collision plate approach each other and squeeze the anti-collision plate, making the anti-collision plate bulge, which plays a good buffering role against the impact of oncoming vehicles. In addition, the expansion baffle expands and covers the bottom, preventing the wheels from crushing the bottom of the left and right support rods. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, a temporary roadblock includes a left support rod 1 and a right support rod 2 that are hinged to each other, and the left support rod 1 and the right support rod 2 have staggered positions that are maintained at a predetermined angle during their movement;

[0024] Anti-collision plates 3 are set opposite to each other and fixedly connected to the left support rod 1 and the right support rod 2 respectively, and the anti-collision plates 3 bulge under the staggered work positions;

[0025] The rotatable expansion baffle 4 is used to limit the opening of the left support rod 1 and the right support rod 2, and the expansion baffle 4 expands in the staggered position to cover the bottom of the left support rod 1 and the right support rod 2.

[0026] Specifically, the upper and lower ends of the crash barrier 3 are fixedly connected to the left support rod 1 and the right support rod 2, respectively. In the default state, the distance between the left support rod 1 and the right support rod 2 is the smallest, and the road barrier is plate-shaped and can be stored in a narrow space. When the road barrier needs to be used, the angle between the left support rod 1 and the right support rod 2 is increased, and the upper and lower ends of the crash barrier 3 move closer to each other and squeeze the crash barrier 3, causing the crash barrier 3 to bulge, which plays a better role in buffering the impact of oncoming vehicles.

[0027] Furthermore, the expansion baffle 4 is rotatably configured relative to the left support rod 1 and the right support rod 2, and the expansion baffle 4 is divided into a left wing and a right wing that are hinged to each other. As the angle between the left support rod 1 and the right support rod 2 increases, the expansion baffle 4 unfolds. The expansion baffle 4 blocks the bottom of the left support rod 1 and the right support rod 2, thereby limiting the opening of the left support rod 1 and the right support rod 2. At this opening, the left support rod 1 and the right support rod 2 reach the maximum angle, i.e., the predetermined angle. At this time, the expansion baffle 4 expands and covers the bottom, preventing the wheels from running over the bottom of the left support rod 1 and the right support rod 2. The expansion baffle 4 can be expanded by setting an inflatable bladder to drive it, or by setting an electric telescopic rod inside the expansion baffle 4 to push against the inner wall of the expansion baffle 4 to expand, or by other methods known to those skilled in the art.

[0028] In the above technology, the left support rod 1 and the right support rod 2 are plate-shaped when not in use and can be stored in a narrow space. When the left support rod 1 and the right support rod 2 are unfolded, the upper and lower ends of the anti-collision plate 3 approach each other and squeeze the anti-collision plate 3, causing the anti-collision plate 3 to bulge, which plays a good buffering role against the impact of oncoming vehicles. In addition, the expansion baffle 4 expands and covers the bottom, preventing the wheels from crushing the bottom of the left support rod 1 and the right support rod 2.

[0029] As a further embodiment of this utility model, the expansion baffle 4 includes a foot plate 42 and a flap 43 fixedly disposed on the foot plate 42, and the expansion baffle 4, the foot plate 42, and the flap 43 form an expansion cavity together.

[0030] Specifically, the angle between the left support rod 1 and the right support rod 2 increases, and the left support rod 1 and the right support rod 2 respectively abut against the foot plate 42, causing the expansion baffle 4 to unfold. During the unfolding process, the angle between the left support rod 1 and the foot plate 42, and between the right support rod 2 and the foot plate 42, decreases, causing the angle between the expansion baffle 4 and the left support rod 1, and between the expansion baffle 4 and the right support rod 2, to increase. The expansion chamber unfolds as follows: Figure 4 As shown, it can expand automatically without any other power source.

[0031] As a further embodiment of this utility model, it also includes a folding rod disposed on the left support rod 1 and the right support rod 2. The folding rod includes a left-turning rod 6 rotatably disposed on the right support rod 2 and a right-turning rod 5 rotatably disposed on the left support rod 1.

[0032] Specifically, when the left support rod 1 and the right support rod 2 are in staggered positions, the angle between the left rotating rod 6 and the right rotating rod 5 increases to 180°. At this time, the folding rod is located between the left support rod 1 and the right support rod 2 and provides internal support, so that the left support rod 1 and the right support rod 2 remain in staggered positions.

[0033] As another embodiment provided by this utility model, an extension rod 62 is slidably provided on the left-hand rotating rod 6, and a limiting member 51 for inserting the extension rod 62 is fixedly provided on the right-hand rotating rod 5.

[0034] Specifically, when the angle between the left turn lever 6 and the right turn lever 5 increases to 180°, the limiting member 51 is located on the extension path of the extension rod 62. At this time, the extension rod 62 is slid to engage with the limiting member 51, which further plays a retaining role. The left support rod 1 and the right support rod 2 are locked together to prevent the left support rod 1 and the right support rod 2 from folding under vehicle impact.

[0035] As another embodiment of the present invention, it also includes an air chamber 61 that forms a piston-like engagement with the extension rod 62.

[0036] Specifically, the expansion chamber is connected to the air chamber 61. The expansion baffle 4 also includes a fixed rod 41 rotatably connected to the pivots of the left rotating rod 6 and the right rotating rod 5, so that the movement of the expansion baffle 4 is synchronized with the opening of the left rotating rod 6 and the right rotating rod 5 through the pivots. The angle between the left support rod 1 and the right support rod 2 increases, and the left support rod 1 and the right support rod 2 respectively abut against the foot plate 42, causing the expansion baffle 4 to unfold, and the expansion chamber unfolds as shown. Figure 4As shown, the angle between the left turn lever 6 and the right turn lever 5 increases to 180°. The limiting member 51 is located on the extension path of the extension rod 62. When the vehicle crashes into the roadblock, the wheels will first crush the expansion chamber. The air in the expansion chamber is squeezed into the air chamber 61 and pushes the extension rod 62 to extend, so that the extension rod 62 is inserted into the limiting member 51, preventing the roadblock from closing under the impact. The roadblock is maintained in the staggered position, causing the anti-collision plate 3 to bulge, which has a better buffering effect on the vehicle that is crashing.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
