Description

Technical Field

[0001] The utility model relates to the technical field of signboards, in particular to a safety signboard for highway engineering. Background Art

[0002] Highway engineering safety signs are used at highway construction or maintenance sites to direct traffic, warn of dangers, and provide information and instructions. The primary purpose of these signs is to ensure safety at the construction site, reduce the risk of accidents, and guide vehicles and pedestrians through the area safely.

[0003] The utility model patent with authorization announcement number CN219497245U in the prior art discloses a safety sign, comprising a support mechanism for quickly propping up the safety sign when in use, an indicator plate for quickly changing the safety sign content, the indicator plate being located in front of the support mechanism, a sweeping mechanism for cleaning dust accumulated on the surface of the safety sign during use, and a pulling mechanism driven by wind to reciprocate the sweeping mechanism. The utility model utilizes a wind wheel to drive the winding wheel to rotate by wind, and the rotation of the winding wheel drives the pulling rope to wind and stretch the coil spring. At this time, the sweeping bar cleans the sign board as the pulling rope is pulled. In addition, when the coil spring is fully stretched, the elastic force of the coil spring drives the sweeping bar to quickly clean the dust.

[0004] However, the patents under the existing technology have the following disadvantages:

[0005] (1) The indicator plate of this utility model safety sign is connected to the entire device and cannot be disassembled. According to different road conditions and different construction operations during highway construction, the safety signs need to be updated in a timely manner. If the indicator plate cannot be disassembled and replaced, the entire safety sign device needs to be replaced, which is cumbersome to operate and multiple safety sign devices are not easy to carry.

[0006] (2) The overall height of this utility model safety sign cannot be adjusted automatically. During highway construction, the overall height of this safety sign is relatively low and cannot be adjusted to a suitable placement height, making it inconvenient for vehicles on the road to observe in a timely manner. Utility Model Content

[0007] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a safety sign for highway engineering which can be disassembled and replaced and whose placement height can be quickly adjusted.

[0030] The lifting assembly 4 includes: a slide rail 1 401, a slide rail 2 402, a lifting frame 403, a connecting block 404, a screw rod 405 and a knob 406. There are two slide rails 1 401, which are fixedly connected to the two ends of the rear side of the frame 1 respectively. The slide rail 2 402 is fixedly connected to the central position of the rear side of the frame 1. The lifting frame 403 is arranged on one side of the slide rail 2 402 of the slide rail 1 401. The connecting block 404 is fixedly connected to the front side of the lifting frame 403. The connecting block 404 is slidingly connected to the slide rail 1 401 and the slide rail 2 402 respectively. The screw rod 405 is rotatably connected to the inner side of the slide rail 2 402. The screw rod 405 is threadedly connected to the connecting block 404. The knob 406 is fixedly connected to the top of the screw rod 405.

[0031] The support assembly 5 includes: a connecting shaft 501, a support rod 502, a support frame 503 and a second plug 504. The connecting shaft 501 is rotatably connected to the inner side of the top of the lifting frame 403. There are two support rods 502 and they are fixedly connected to the two ends of the connecting shaft 501 respectively. The support frame 503 is rotatably connected to the rear bottom of the lifting frame 403. Several second sockets 505 are provided on both sides of the support frame 503. The second plug 504 passes through the support rod 502 and the support frame 503 and is slidably connected to the inner side of the second socket 505. The second plug 504 can be pulled out and removed from the inner side of the second socket 505.

[0032] The locking assembly 3 includes: a pull ring 301, a bolt 302, a limit ring 303 and a spring 304.
