Description

Technical Field

[0001] This utility model relates to the field of highway maintenance engineering technology, specifically a foldable warning barrier for highway maintenance engineering. Background Technology

[0002] Road maintenance is the upkeep and maintenance of highways. Upkeep focuses on the entire process of maintenance from the time the road is built and opened to traffic, while maintenance focuses on repairing the damaged parts. When the road surface needs to be repaired and maintained, construction workers use warning barriers to separate the area that needs to be repaired and maintained from the area that vehicles can pass through, so as to ensure the safety of construction workers and vehicles.

[0003] Existing foldable warning barriers are not convenient to adjust in length and angle according to the usage scenario, which greatly reduces their effectiveness and makes them inconvenient to use. Therefore, a foldable warning barrier for highway maintenance projects is proposed. Utility Model Content

[0004] In view of this, the present invention provides a foldable warning barrier for highway maintenance projects to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model is implemented as follows: a foldable warning barrier for highway maintenance engineering includes three connecting mechanisms and a folding mechanism. The connecting mechanism includes a column, and a fixing plate is rotatably connected to both sides of the column. A groove is opened on the front surface of the fixing plate, and two sliders are slidably connected to the inner side wall of the groove. The two sliders are respectively fixedly connected to a first threaded rod on the front surface and the rear surface.

[0006] The folding mechanism includes multiple first links and multiple second links. The multiple second links are respectively disposed on the front surface of the multiple first links. The front surfaces of the multiple first links and the multiple second links are symmetrically provided with three through holes. The inner sidewall of the through holes is inserted with a second threaded rod.

[0007] More preferably, the outer walls of the first threaded rod and the second threaded rod are threaded with nuts.

[0008] More preferably, a base is fixedly connected to the bottom of the column.

[0009] Preferably, a warning light is installed on the top of the column.

[0010] More preferably, the first threaded rod is inserted into the inner wall of the through hole.

[0011] The present invention has the following advantages due to the adoption of the above technical solution:

[0012] In the process of using this utility model, the number of the first link, the second link, and the column is selected according to the actual use scenario. Then, the column and the first and second links are assembled. The connection between the column and the first and second links can be rotated to adjust the angle between the column and the first and second links, thereby adapting to the use scenario and improving the use effect.

[0013] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figure 1-3As shown, this utility model embodiment provides a foldable warning barrier for highway maintenance engineering, including three connecting mechanisms 1 and a folding mechanism 2. The connecting mechanism 1 includes a column 11, and a fixing plate 12 is rotatably connected to both sides of the column 11. A groove 13 is provided on the front surface of the fixing plate 12. Two sliders 14 are slidably connected to the inner side wall of the groove 13. The two sliders 14 are respectively fixedly connected to a first threaded rod 15 on the front surface and the rear surface.

[0022] The folding mechanism 2 includes multiple first links 21 and multiple second links 22. The multiple second links 22 are respectively disposed on the front surface of the multiple first links 21. The front surfaces of the multiple first links 21 and the multiple second links 22 are symmetrically provided with three through holes 23. The inner sidewall of the through holes 23 is inserted with a second threaded rod 24.

[0023] In one embodiment, the outer walls of the first threaded rod 15 and the second threaded rod 24 are threaded with nuts 25. By setting the nuts 25, after the first connecting rod 21 and the second connecting rod 22 are connected by the first threaded rod 15 and the second threaded rod 24, the nuts 25 are installed on the first threaded rod 15 and the second threaded rod 24, which has the effect of limiting the position of the first connecting rod 21 and the second connecting rod 22.

[0024] In one embodiment, a base 16 is fixedly connected to the bottom of the column 11; the stability of the column 11 is improved by the setting of the base 16.

[0025] In one embodiment, a warning light 17 is installed on the top of the column 11; the warning light 17 serves to alert pedestrians and vehicles passing by.

[0026] In one embodiment, the first threaded rod 15 is inserted into the inner wall of the through hole 23; by inserting the first threaded rod 15 into the through hole 23 on the first connecting rod 21 and the second connecting rod 22, the first connecting rod 21 and the second connecting rod 22 are fixed.

[0027] In operation, this invention works as follows: First, the number of the first connecting rod 21, the second connecting rod 22, and the column 11 are selected according to the usage requirements. The first threaded rod 15 on the column 11 is inserted into the through hole 23 of the first connecting rod 21 and the second connecting rod 22 to fix the position of the first connecting rod 21 and the second connecting rod 22. Then, the first connecting rod 21 and the second connecting rod 22 are connected by the second threaded rod 24. After connecting the first connecting rod 21 and the second connecting rod 22 by the first threaded rod 15 and the second threaded rod 24, the nut 25 is installed on the first threaded rod 15 and the second threaded rod 24 to limit the position of the first connecting rod 21 and the second connecting rod 22. When folding the first connecting rod 21 and the second connecting rod 22, the position of the column 11 is adjusted so that the first connecting rod 21 and the second connecting rod 22 move closer to one side. The slider 14 slides on the slide groove 13 to adjust the position so that the first connecting rod 21 and the second connecting rod 22 are folded with the column 11.
