Description

Technical Field

[0001] The utility model relates to a roadblock, more specifically, it relates to a roadblock. Background Art

[0002] A roadblock is an obstacle that blocks road traffic. It can refer to a barrier used as a fence during road construction. In municipal construction, roadblocks are usually set up on existing roads to remind drivers to change routes due to the construction or reconstruction of roads.

[0003] At present, when isolating the location of municipal construction, it is necessary to place more roadblocks for isolation and warning, which wastes resources. Moreover, the roadblocks are placed at intervals, but pedestrians or vehicles can still pass through the empty space in the middle, which poses a great safety hazard. In order to solve the above problems, a municipal construction roadblock with announcement number: CN219327019U is proposed, which achieves the effect of blocking the middle by connecting two roadblocks to each other, thereby preventing pedestrians or vehicles from passing through the middle.

[0004] However, the following problems still exist: 1. The middle pole is not easily observed by the driving personnel, so the vehicle still passes through the middle of the roadblock, causing damage to the equipment. 2. Since the middle pole is straight, it cannot circle a curve. When the obstruction range is too large and unreasonable, it will cause traffic pressure and affect driving speed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a road barrier that can improve the visual effect and can flexibly circle the curve range of the road barrier.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a road barrier, comprising a base, a road barrier body and a connecting piece, wherein the road barrier body is installed on the base, and the connecting piece is used to connect two adjacent road barrier bodies;

[0007] The connecting member includes a central axis tube, a connecting rod and a sliding rod. The connecting rod and the sliding rod are both provided with two groups. A rotating shaft and a limiting screw are provided at both ends of the central axis tube. The two connecting rods are respectively rotatably connected to the rotating shafts on both sides. The limiting screw is used to limit the rotation of the connecting rod.

[0008] The sliding rod is slidably connected to an end of the connecting rod away from the central shaft tube;

[0009] The connecting rod and / or the sliding rod are provided with a reflective strip.

[0010] In summary, the utility model has the following beneficial effects: by utilizing the design of the central axis tube and the connecting rod, the connecting rod can be horizontally rotated around the rotation axis, thereby adjusting the angle between the two roadblock bodies, so that the arrangement of multiple roadblocks can be adjusted according to road conditions, thereby adapting to the terrain and avoiding excessively large circling areas that cause road congestion.

[0011] Then, the distance between the roadblock body and the connecting rod is adjusted by the sliding rod, thereby achieving the effect of adjusting the distance between the two roadblock bodies.

[0012] The device is not only provided with reflective strips on the roadblock body, but also on the connecting rod and / or the sliding rod, which can increase the visible area and prevent drivers from forcing through at night by thinking that there is no blocking member between the two roadblocks.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] Reference Figures 1 to 6 As shown, in order to achieve the above purpose, the utility model provides the following technical solutions: a road barrier, comprising a base 1, a road barrier body 2 and a connecting member 3, the road barrier body 2 is installed on the base 1, and the connecting member 3 is used to connect two adjacent road barrier bodies 2;

[0022] The connecting member 3 includes a central axis tube 31, a connecting rod 32 and a sliding rod 33. The connecting rod 32 and the sliding rod 33 are each provided with two groups. A rotating shaft and a limit screw 4 are provided at both ends of the central axis tube 31. The two connecting rods 32 are respectively rotatably connected to the rotating shafts on both sides. The limit screw 4 is used to limit the rotation of the connecting rod 32. When the angle of the connecting rod 32 needs to be adjusted, the limit screw 4 is rotated so that the limit screw 4 moves up and separates from the connecting rod 32. After the position of the connecting rod 32 is adjusted, the limit screw 4 is rotated downward so that the limit screw 4 abuts against the connecting rod 32, thereby limiting the rotation of the connecting rod 32.

[0023] The sliding rod 33 is slidably connected to one end of the connecting rod 32 away from the middle shaft tube 31;

[0024] The connecting rod 32 and / or the sliding rod 33 are provided with a reflective strip 5. In the first embodiment, the connecting rod is provided with a reflective strip; in the second embodiment, the sliding rod is provided with a reflective strip; and in the third embodiment, the connecting rod and the sliding rod are provided with a reflective strip.

[0025] The design of the utility model utilizes the design of the central axis tube 31 and the connecting rod 32, so that the connecting rod 32 can rotate horizontally around the rotation axis, thereby adjusting the angle between the two roadblock bodies 2, so that the arrangement of multiple roadblocks can be adjusted according to road conditions, thereby adapting to the terrain and avoiding excessively large circling areas that cause road congestion.

[0026] Then, the distance between the roadblock body 2 and the connecting rod 32 is adjusted by the sliding rod 33 , thereby achieving the effect of adjusting the distance between the two roadblock bodies 2 .

[0027] In this device, not only the roadblock body 2 is provided with a reflective strip 5, but also the connecting rod 32 and / or the sliding rod 33 are provided with a reflective strip 5, which can increase the visible area and prevent drivers from forcing through at night by thinking that there is no blocking member between the two roadblocks.

[0028] The sliding rod 33 is provided with a plurality of groups of limiting holes 331 along its length direction. The connecting rod 32 is provided with a positioning hole 321 . The positioning hole 321 and the limiting hole 331 are connected by a positioning member 6 .

[0029] The first embodiment of the positioning member: the positioning hole 321 is a threaded hole, and the positioning member 6 includes a threaded rod. The design of this structure is that the threaded rod is rotated and inserted into the corresponding limiting hole 331 to fix the sliding rod 33.

[0030] Second embodiment of the positioning member: The positioning member 6 includes a positioning column 61, a positioning plate 62 and a positioning spring 63. The positioning column 61 and the positioning plate 62 are enclosed to form a T-shaped structure. The positioning spring 63 is sleeved on the positioning column 61. One end of the positioning spring 63 is connected to the lower end of the positioning plate 62, and the other end is connected to the outer end of the connecting rod 32. The design of this structure requires that the positioning plate 62 is pulled upward so that the positioning spring 63 is stretched. When the limiting hole 331 moves to below the positioning hole 321, the positioning column 61 is pulled by the positioning spring 63 and inserted downward into the limiting hole 331, so that the connecting rod 32 and the sliding rod 33 are limited.

[0031] A limit plate 322 is provided in the connecting rod 32, and a positioning spring 323 is provided between the limit plate 322 and the sliding rod 33. The design of the positioning spring 323 can pull the sliding rod 33 to move toward the limit plate 322, so that when not in use, the length of the connecting member 3 can be automatically shortened, thereby reducing the floor space.

[0032] The outer side of the sliding rod 33 is provided with a positioning groove 332, and the positioning grooves 332 are provided in multiple groups and are arranged equidistantly along the length direction of the sliding rod 33;

[0033] An elastic block 324 adapted to the positioning groove 332 is disposed on the inner side of the connecting rod 32 .

[0034] There are multiple groups of elastic blocks 324 , which are arranged equidistantly along the length direction of the connecting rod 32 .

[0035] With the design of this structure, the spacing between the elastic blocks 324 is consistent with the spacing between the positioning grooves 332 and the spacing between the limiting holes 331, so that there is a sense of frustration when pulling the sliding rod 33, which facilitates the correspondence between the limiting holes 331 and the positioning holes 321 during the pulling process.

[0036] The roadblock body 2 is provided with a plug-in hole 21, and an elastic limiting sleeve 22 is provided in the plug-in hole 21. The limiting sleeve 22 forms a limited space 23, and the diameter length of the limited space 23 gradually decreases. The design of this structure can conveniently fix the sliding rod 33 to the roadblock body 2 by plugging, and improve the connection strength through the elastic limiting sleeve 22.

[0037] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
