[0002] With the increase of modern population, in densely populated places, people and vehicles are mixed together, which easily leads to traffic paralysis; or road facilities are damaged due to long-term lack of maintenance; it is necessary to impose certain restrictions on people and vehicles in the area around the road. If long-term blocking facilities are built, it is easy to cause the defects of high economic pressure and low number of uses. At this time, a temporary blocking device is urgently needed to limit the traffic in the target range.

[0034] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0035] The working principle of the utility model is as follows Figure 1-Figure 7 As shown, a temporary blocking device for traffic engineering includes a column 1, an indicator light 101 is fixedly connected to the front end of the column 1, when the indicator light 101 is on, it indicates that traffic control is carried out in the area, grooves 2 are opened on both sides of the column 1, and cover plates 3 are rotatably connected to the front and rear end inner walls of the grooves 2 on both sides, and the cover plate 3 is connected to the inner wall of the groove 2 on the side close to each other by setting a supporting structure 4. When the cover plate 3 is lifted, the support structure 4 can be used to support the cover plate 3 in a fixed position to ensure that the cover plate 3 will not fall off halfway. The grooves 2 on both sides are A through groove 25 is provided at the bottom of the adjacent side of the inner wall, and telescopic structures 6 are provided on both sides of the bottom end of the inner wall of the groove 25, so that the telescopic structure 6 is hidden in the groove 25 and will not be damaged when not in use. The bottom end of the column 1 is rotatably connected to the supporting base plate 7, so that traffic control can be carried out in multiple directions by only limiting the device to one place. Stable structures 8 are provided on both sides of the front and rear ends of the supporting base plate 7, and the stable structure 8 can make the device run more stably. A plurality of universal wheels 701 are fixedly connected to the bottom end of the supporting base plate 7.

[0036] The above-mentioned structures together constitute the general appearance structure of a temporary blocking device for traffic engineering of the utility model.

[0037] To further explain the specific working principle of a temporary blocking device for traffic engineering of the utility model, the supporting structure 4 includes a supporting column 401 hinged to the upper part of the cover plate 3 close to the groove 2, and the end of the supporting column 401 away from the cover plate 3 is rotatably connected to the supporting column 2 402, and the supporting column 2 402 is hinged on the inner wall of the groove 2. When the supporting column 401 and the supporting column 2 402 are connected in a straight line, in order to ensure the supporting effect on the cover plate 3, a fixing sleeve 403 is threadedly connected to the supporting column 2 402, and the fixing sleeve 403 limits the rotation of the supporting column 401 and the supporting column 2 402 when the supporting column 401 and the supporting column 2 402 are connected in a straight line.

[0038] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the cover plate 3 is flipped upward, the support column 1 401 and the support column 2 402 will rotate. When they rotate to a straight line, the fixing sleeve 403 on the support column 2 402 is rotated, and when the fixing sleeve 403 is rotated to the connection between the support column 1 401 and the support column 2 402, the relative rotation of the support column 1 401 and the support column 2 402 can be limited, thereby achieving support for the cover plate 3.

[0039] In order to further explain the specific working principle of a temporary blocking device for traffic engineering of the utility model, the telescopic structure 6 includes a first-level telescopic rod 601 fixedly connected to both sides of the bottom end of the inner wall of the groove 2 5, and a second-level telescopic rod 602 is slidably connected inside the first-level telescopic rod 601. The second-level telescopic rod 602 and the first-level telescopic rod 601 are interconnected by a telescopic cylinder 603. When the telescopic cylinder 603 is extended, the second-level telescopic rod 602 is simultaneously brought out of the first-level telescopic rod 601, and a third-level telescopic rod 604 is slidably connected inside the second-level telescopic rod 602. The second-level telescopic rod 602 and the third-level telescopic rod 604 are interconnected by a fixing device 9. The fixing device 9 can ensure that the third-level telescopic rod 604 can only slide inside the second-level telescopic rod 602.

[0040] In order to allow the three-stage telescopic rod 604 to come out automatically, a spring 605 is fixedly connected to the middle of the inner wall on the side where the two-stage telescopic rods 602 on both sides are close to each other. The spring 605 can provide sufficient elastic force to bounce the three-stage telescopic rod 604 to a specified position. At the same time, a pushing block 606 is fixedly connected to a position of the spring 605 close to one end of the three-stage telescopic rod 604. The pushing block 606 and the three-stage telescopic rod 604 are movably connected. In order to ensure that the spring 605 does not shake randomly, a damper 607 is provided in the spring 605, and the two ends of the damper 607 are respectively fixedly connected to the two-stage telescopic rod 602 and the pushing block 606.

[0041] The technical effect achieved by the technical solution composed of the above-mentioned technical features is as follows: the first-stage telescopic rod 601 is fixed on the inner wall at the bottom end of the groove 2 5 and does not move. The telescopic cylinder 603 first extends to bring the second-stage telescopic rod 602 out of the first-stage telescopic rod 601. When the maximum stroke is reached, the fixing device 9 is released, and the spring 1 605 and the damper 1 607 push the pushing block 606 together. At the same time, the pushing block 606 pops out the third-stage telescopic rod 604 to the specified position.

[0042] In order to further explain the specific working principle of a temporary blocking device for traffic engineering of the utility model, the fixing device 9 includes a groove three 901 set at one side away from each other at the top of the secondary telescopic rod 602 on both sides, and the front part of the inner wall of the groove three 901 is rotatably connected with a positioning pin 902, and the upper end of the positioning pin 902 is fixedly connected with a rotating plate 903. In order to fix the three-stage telescopic rod 604, a fixed shaft 906 is fixedly connected to the rear end of the bottom end of the rotating plate 903. The fixed shaft 906 passes through the groove three 901 and extends to the outside of the groove three 901. It is worth noting that the groove three 901 reserves enough space to ensure the rotation of the rotating plate 903 and the rotation of the fixed shaft 906 around the positioning pin 902. At the same time, a number of evenly distributed grooves 907 are opened on the sides away from the top of the three-stage telescopic rod 604 on both sides. The several grooves 907 can make the three-stage telescopic rod 604 stay at different positions. The fixed shaft 906 and the grooves 907 are used in conjunction with each other. In order to allow the rotating plate 903 to be better reset after being pressed, a spring 904 is fixedly connected to the middle of the bottom end of the rotating plate 903. The bottom end of the spring 904 is fixedly connected to the bottom end of the inner wall of the groove 3 901. At the same time, a damper 905 with the same function as the damper 1 607 is also arranged in the spring 904. The upper and lower ends of the damper 905 are respectively hinged to the bottom end of the rotating plate 903 and the bottom end of the inner wall of the groove 3 901.

[0043] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the front end of the rotating plate 903 is pressed, the fixed shaft 906 at the rear bottom end of the rotating plate 903 is pulled out from the groove four 907. At this time, the three-stage telescopic rod 604 slides in the two-stage telescopic rod 602. When the three-stage telescopic rod 604 slides to the specified position, the groove three 901 and the next groove four 907 are aligned, the rotating plate 903 is released, the damper two 905 and the spring two 904 reset the rotating plate 903, and the fixed shaft 906 returns to the groove four 907.

[0044] In order to further explain the specific working principle of a temporary blocking device for traffic engineering of the utility model, the stabilizing structure 8 includes a rotating column 801 rotatably connected to the front and rear ends of the supporting base plate 7, the rotating column 801 can rotate freely within a range of 180°, and the side of the rotating columns 801 on the front and rear ends away from the supporting base plate 7 is plugged with a connecting column 802, the connecting column 802 slides freely in the rotating column 801, and the side of the connecting column 802 away from the rotating column 801 is fixedly connected with a fixed block 803, and the bottom end of the fixed block 803 is threadedly connected with a threaded column 804, the threaded column 804 can adjust the height of the entire device, and the bottom end of the threaded column 804 is fixedly connected with a support block 805 that supports the entire device, so that the device can be adjusted in multiple dimensions, so that the device can operate normally under a variety of different environments.

[0045] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: first, the four rotating columns 801 at the front and rear ends are respectively rotated to a suitable angle, and then the connecting column 802 is stretched from the rotating column 801 to a suitable position. When the height in the vertical direction needs to be adjusted, it is only necessary to rotate the threaded column 804 at the bottom end of the fixed block 803. Thus, the stabilizing device can enable the entire equipment to operate stably in different scenarios.

[0046] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
