Detailed implementation manners
[0026] The present application will be further described in detail below with reference to the accompanying drawings of the specification.
[0027] A road construction isolation warning device, comprising: a guardrail 100, the guardrail 100 includes a first upright post 1, a second upright post 2, two first horizontal pipes 3 vertically fixed at both ends of the first upright post 1, two second horizontal pipes 4 vertically fixed at both ends of the second upright post 2, multiple first railings 5 vertically fixed between the two first horizontal pipes 3 and multiple second railings 6 vertically fixed between the two second horizontal pipes 4. Support legs 7 are fixed at the lower ends of the first upright post 1 and the second upright post 2. The support legs 7 can be adjusted into a "cross" shape and a "one" shape. A solar warning light 200 is fixedly installed on the upper first horizontal pipe 3. The first railing 5 is placed in front of the second railing 6, and the second horizontal pipe 4 is slidably inserted into the first horizontal pipe 3.
[0028] Refer to Figures 1 - 8 , the solar warning light 200 is used to flash and warn the isolation area, and the second horizontal pipe 4 slides and inserts along the first horizontal pipe 3 to adjust the lateral width of the guardrail 100. With the cooperation of multiple first railings 5 and second railings 6, the isolation and protection effect of the guardrail 100 is ensured. And the second railing 6 is placed behind the first railing 5. Therefore, when storing, the first railing 5 does not affect the sliding of the second railing 6. At the same time, when the support legs 7 are in the "cross" shape, the support range of the support legs 7 is increased to improve the support stability. When the bottom support area of the support legs 7 is in the "one" shape, the space occupied by the support legs 7 is reduced to facilitate the overall storage.
[0029] Strip-shaped holes 31 are opened on opposite sides of the first horizontal pipe 3. One end of the strip-shaped hole 31 away from the first upright post 1 is an open structure. The strip-shaped hole 31 is placed behind the first railing 5. The second railing 6 slides along the strip-shaped hole 31. Multiple first screws 51 are threadedly connected to the first railing 5 on the side away from the first upright post 1. Positioning holes 61 corresponding to and adapted to the first screws 51 are opened on both outer second railings 6.
[0030] Refer to Figures 1 - 5 , the second horizontal pipe 4 is slidably inserted into the first horizontal pipe 3, and the second railing 6 corresponds to the strip-shaped hole 31. The first railing 5 is placed at one side edge of the strip-shaped hole 31. Therefore, when the second horizontal pipe 4 slides and adjusts in the first horizontal pipe 3, at this time the second railing 6 slides in the strip-shaped hole 31. And when the first screw 51 is inserted into the positioning hole 61 on the second railing 6 on the side away from the second upright post 2, the guardrail 100 with an increased lateral width can be fixed at this time (refer to Figure 1 ). When in the storage state, the first screw 51 is inserted into the positioning hole 61 on the second railing 6 on the side close to the second upright post 2, and the fixing of the guardrail 100 after storage can be completed at this time (refer to Figure 2 ).
[0031] On one side, a second screw rod 52 is threadedly connected to the first railing 5. An indicating arrow board 8 is installed on the second screw rod 52. The indicating arrow board 8 is provided with a mounting hole 82, and a reflective sticker 81 is pasted on the surface of the indicating arrow board 8.
[0032] Refer to Figure 2 and Figure 4 and Figure 7 , after the second screw rod 52 passes through the mounting hole 82, it is threadedly connected to the first railing 5. By flipping the indicating arrow board 8, the indicating direction of the arrow can be changed, so as to adjust the guiding direction according to the usage situation. After the adjustment is completed, by rotating the second screw rod 52 clockwise, under the action of extrusion and / or friction, the indicating arrow board 8 is fixed on the first railing 5.
[0033] The support leg 7 includes a U-shaped leg 71, a shaft rod 72 fixed at the center of the lower end of the U-shaped leg 71, and a support plate 73 rotatably arranged at the lower end of the shaft rod 72. A stepped hole 731 is provided at the center of the support plate 73. Two limiting rings 721 are fixed at the lower end of the shaft rod 72, and the limiting rings 721 are placed on the upper and lower sides of the support plate 73. The length of the support plate 73 is less than the opening distance of the U-shaped leg 71.
[0034] Refer to Figure 1 , Figure 2 , Figure 6 and Figure 8 , the shaft rod 72 passes through the stepped hole 731, and the limiting ring 721 is larger than the outer diameter of the stepped hole 731 to realize the rotational connection between the support plate 73 and the shaft rod 72 and prevent it from falling off the shaft rod 72. At the same time, the lower surface of the support plate 73 is coplanar with the lower end of the U-shaped leg 71. The support plate 73 rotates within the bottom opening of the U-shaped leg 71 and is parallel to the first cross tube 3. At this time, a cross state is formed between the U-shaped leg 71 and the support plate 73. When the support plate 73 is perpendicular to the first cross tube 3, the support plate 73 is received inside the opening of the U-shaped leg 71 to complete the storage.
[0035] A plurality of mounting sleeves 11 are fixed on the first column 1, and a plurality of L-shaped rods 21 matching the mounting sleeves 11 are fixed on the second column 2.
[0036] Refer to Figure 2 , insert the L-shaped rod 21 between adjacent two groups of guardrails 100 into the mounting sleeve 11 to facilitate the connection of adjacent two groups of guardrails 100.
[0037] L-shaped support frames 53 are fixed on the first railing 5 on both sides of the second screw rod 52, and the indicating arrow board 8 is placed on the support frames 53.
[0038] Refer to Figure 2 and Figure 4, after the indicating arrow board 8 is turned over, the indicating arrow board 8 can be placed on the support frame 53 on the corresponding side to improve the support stability of the indicating arrow board 8 and prevent the indicating arrow board 8 from deflecting due to the loosening of the second screw 52.
[0039] Working principle: When it is necessary to adjust the lateral width of the guardrail 100 to be lengthened, loosen the first screw 51, the first screw 51 disengages from the positioning hole 61, then separate and adjust the first upright post 1 and the second upright post 2, and make the first railing 5 and the second railing 6 away from the upright post coincide. At the same time, rotate the first screw 51 clockwise so that the first screw 51 is screwed into the positioning hole 61 on the second railing 6 on the side away from the second upright post 2 to complete the overall fixation of the guardrail 100. And by rotating the support plate 73, make the support plate 73 perpendicular to the first horizontal pipe 3. At this time, the U-shaped legs 71 and the support plate 73 are in a cross state to increase the overall bottom support area. Then, according to the direction of vehicle and / or pedestrian travel, turn over and adjust the indicating arrow board 8 and place it on the support frame 53 on the corresponding side so that the indicating arrow board 8 points to the direction of vehicle and / or pedestrian travel. Finally, rotate the second screw 52 clockwise, and complete the fixation of the indicating arrow board 8 by the extrusion of the second screw 52. Under the action of the solar warning light 200, the isolated and protected area is flashed and warned.
