[0002] In road management, height limiting pole is the important device for guaranteeing the safety of road and overhead facilities. The traditional height limiting pole is mostly fixed height, and cannot adapt to the change of height limiting requirement in different periods and different sections. For example, during the construction of some roads, the height limiting may need to be temporarily lowered;Or when special vehicles (such as high engineering rescue vehicles) need to pass, the height limiting needs to be temporarily increased. However, the existing adjustable height limiting pole is often complicated in adjustment process, needs to be assisted by various tools, consumes a lot of time and manpower, and cannot meet the demand for quick adjustment in actual use.

[0003] The existing patent (authorized announcement number: CN221118313U) discloses a height-adjustable municipal road height limiting pole, which realizes the display of the elevation by setting a prompt component. The device is sleeved outside the fixed column through the sleeve, and the locking bolt can be rotated and moved, so that the shaft end of the locking bolt can be extruded outside the fixed column during movement, and then the prompt signboard can be fixed. The plug-in installation mode of the prompt signboard can improve the convenience of disassembly and assembly of the prompt signboard.

[0004] However, the above technical solution still has certain defects. In actual use, the height of the height limiting pole is adjusted at any time according to actual conditions, so the disassembly and assembly frequency of the prompt signboard is relatively high. The prompt signboard in the above device is fixed by bolt, which on the one hand leads to low disassembly and assembly efficiency of workers, and on the other hand is time-consuming and laborious every time. On the other hand, the height limiting pole is mostly used outdoors, and the bolt will rust after long time use, which affects the subsequent workers during disassembly.

[0028] In the embodiment, when the prompt signboard 180 is installed, the worker only needs to align the T-shaped clamping plate 370 at the back of the prompt signboard 180 with the clamping groove 320 on the fixing seat 310, and then push the prompt signboard 180 so that the T-shaped clamping plate 370 is inserted into the clamping groove 320. During the insertion process, the lower end of the T-shaped clamping plate 370 will press the arc surface of the trapezoidal clamping block 330, so that the trapezoidal clamping block 330 moves into the movable cavity. At this time, the limiting spring 350 is pressed. When the lower end of the T-shaped clamping plate 370 is inserted to the bottom end of the clamping groove 320, the elastic potential energy of the limiting spring 350 is used to push a part of the trapezoidal clamping block 330 to move out of the movable cavity and to the back of the bottom end of the T-shaped clamping plate 370, so that the T-shaped clamping plate 370 and the prompt signboard 180 can be quickly fixed. When it is necessary to disassemble, the pull rod 340 is moved by pulling the pull handle 360, and then a force is applied to the trapezoidal clamping block 330 to pull it backward, so that the trapezoidal clamping block 330 is separated from the back of the bottom end of the T-shaped clamping plate 370, and the limiting is released. By arranging the clamping assembly 300, the convenience of disassembling the prompt signboard 180 is improved, and the work efficiency is further improved.

The outer wall of the lower end of the lead screw 210 is fixedly sleeved with a worm gear 220. One side of the worm gear 220 is engaged with a worm 230. A motor 240 for driving the worm 230 to rotate is fixedly installed on the outer wall of the first support column 101. A threaded sleeve 250 is threadedly connected to the outer wall of the lead screw 210. One end of the threaded sleeve 250 extends to the outside of the first support column 101 and is fixedly connected with one end of the height limiting rod frame 130. A guide rod 260 is longitudinally arranged in the second support column 102. A sliding block 270 is slidingly connected to the outer wall of the guide rod 260. One end of the sliding block 270 extends to the outside of the second support column 102 and is fixedly connected with the other end of the height limiting rod frame 130. When it is necessary to adjust the height of the height limiting rod frame 130, the motor 240 is started. The output end of the motor 240 drives the worm 230 to rotate, thereby driving the worm gear 220 engaged therewith to rotate, so that the lead screw 210 rotates synchronously, thereby driving the threaded sleeve 250 to move up and down, and in turn driving the height limiting rod frame 130 fixedly connected with one end of the threaded sleeve 250 to move up and down until the specified height is reached. By arranging the lifting assembly 200, the height of the height limiting rod frame 130 can be adjusted according to the actual situation, thereby improving the practicality of the device.

[0033] The above embodiment discloses a road height limiting rod structure capable of being quickly adjusted. When the prompt signboard 180 is installed, the rear T-shaped clamping plate 370 is aligned with the clamping groove 320 on the fixing seat 310 and pushed, the T-shaped clamping plate 370 is inserted, the arc surface of the trapezoidal clamping block 330 is extruded, the trapezoidal clamping block 330 moves to the movable cavity, and the limiting spring 350 is extruded; when the lower end of the T-shaped clamping plate 370 is inserted into the bottom end of the clamping groove 320, the elastic potential energy of the limiting spring 350 pushes the trapezoidal clamping block 330 to move out of the movable cavity, and the trapezoidal clamping block 330 is clamped to the bottom end of the back of the T-shaped clamping plate 370, thereby realizing the quick fixing of the T-shaped clamping plate 370 and the prompt signboard 180. When disassembled, the pull rod 340 is moved by pulling the pull handle 360, the trapezoidal clamping block 330 is pulled backward, the trapezoidal clamping block 330 is separated from the bottom end of the back of the T-shaped clamping plate 370, and the limiting is released. Through the above principle of the clamping assembly 300, the convenience and working efficiency of disassembly and assembly of the prompt signboard 180 are improved.

[0034] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
