[0031] Municipal engineering refers to the construction of municipal infrastructure. In my country, municipal infrastructure refers to various buildings, structures, and equipment that are set up within the planning and construction scope of urban areas and towns to provide paid or free services to residents.

[0032] Current warning devices are generally composed of a support frame and a warning plate welded together. Due to their large space requirements and inability to be disassembled or folded, they are very inconvenient to transport and carry.

[0033] Reference Figures 1 to 4 This application provides a warning device for municipal construction, including a sleeve 100, a telescopic rod 200, an adjusting screw 300, a warning sign 400, and a bracket 500.

[0034] The telescopic rod 200 is slidably assembled in the sleeve 100. One end of the telescopic rod 200 extends out from one end of the sleeve 100, and the other end of the telescopic rod 200 is provided with a threaded hole 202. One end of the adjusting screw 300 passes through the sleeve 100 and is assembled in the threaded hole 202. The other end of the adjusting screw 300 is located outside the sleeve 100. The warning sign 400 is fixed to the end of the telescopic rod 200 that extends out of the sleeve 100. The bracket 500 includes a sliding sleeve 510, a connecting rod 520, and at least three support rods 530. One end of each support rod 530 is hinged to the sleeve 100, and the other end is used to support the ground. The support rods 530 are distributed at intervals around the sleeve 100. The sliding sleeve 510 is slidably assembled on the outer wall of the sleeve 100. Multiple connecting rods 520 are provided. A connecting rod 520 is provided between each support rod 530 and the sliding sleeve 510. One end of the connecting rod 520 is hinged to the sliding sleeve 510, and the other end is hinged to the support rod 530.

[0035] When using the device, the sliding sleeve 510 opens each support rod 530 to support it on the ground, keeping the sleeve 100 vertical. By rotating the adjusting screw 300, the telescopic rod 200 can drive the warning sign 400 to rise and fall. When transporting the device, the sliding sleeve 510 retracts each support rod 530. Therefore, this application has the function of folding and reducing size, occupying less space and facilitating transportation.

[0036] The sleeve 100 is vertically arranged, and the upper end of the sleeve 100 has an opening with the same inner diameter as the sleeve 100. The telescopic rod 200 can slide in the sleeve 100 to realize the lifting and lowering movement. The upper end of the telescopic rod 200 extends from the upper end of the sleeve 100, and a warning sign 400 is installed on the upper end of the telescopic rod 200.

[0037] To facilitate the disassembly and installation of the warning sign 400 and the telescopic pole 200, in some embodiments, a mounting groove is provided at one end of the telescopic pole 200 extending out of the sleeve 100, and a fixing bolt 201 passing through the mounting groove is provided at the same end of the telescopic pole 200 extending out of the sleeve 100. One side of the warning sign 400 is inserted into the mounting groove and fixed by the fixing bolt 201. This makes the installation of the warning sign 400 more convenient. During transportation, the warning sign 400 can be removed from the telescopic pole 200, and when needed, it can be reinstalled on the telescopic pole 200.

[0038] The lower end of the sleeve 100 is provided with a through hole 101 for cooperating with the adjusting screw 300. The lower end of the telescopic rod 200 is provided with a threaded hole 202 extending along the axial direction of the telescopic rod 200. The adjusting screw 300 passes through the through hole 101 at the lower end of the sleeve 100 and is connected to the threaded hole 202 of the telescopic rod 200. When it is necessary to adjust the height of the telescopic rod 200, the adjusting screw 300 is rotated, and the telescopic rod 200 is driven to slide up and down in the sleeve 100 by the adjusting screw 300, so as to realize the adjustment of the height of the warning sign 400.

[0039] A retaining ring 102 is installed at the lower end of the sleeve 100. The retaining ring 102 is used to block the sliding sleeve 510 and prevent the sliding sleeve 510 from sliding out from the lower end of the sleeve 100.

[0040] To facilitate the rotation of the adjusting screw 300 by the operator, in some embodiments, a knob 320 is fixedly installed at one end of the adjusting screw 300 outside the sleeve 100. Specifically, the knob 320 is vertically fixed to the end of the adjusting screw 300, and the knob 320 is provided with friction texture to increase the contact friction.

[0041] In the embodiment shown in this application, three support rods 530 are provided, and the three support rods 530 are arranged at equal intervals around the sleeve 100. Of course, the number of support rods 530 can also be set to four or more according to actual use needs, as long as the support ends of each support rod 530 form a plane.

[0042] In some embodiments, the bracket 500 further includes a fixing plate 540, which is fixed to the middle of the sleeve 100, and the support rod 530 is hinged to the fixing plate 540.

[0043] like Figure 1 As shown, the fixing plate 540 is vertically fixed to the outer wall of the sleeve 100 and located in the middle of the sleeve 100. One end of each support rod 530 is hinged to the fixing plate 540 through a pivot. The fixing plate 540 makes it easier to connect the support rods 530 to the sleeve 100.

[0044] To ensure that the telescopic rod 200 slides linearly within the sleeve 100, in some embodiments, a groove 110 is provided on the sleeve 100, extending through the sleeve wall. The groove 110 extends along the length of the sleeve 100, and both ends of the groove 110 are a certain distance from both ends of the sleeve 100. A slider 210 is provided on the outer wall of the telescopic rod 200, and the slider 210 engages with the groove 110. During the process of rotating the adjusting screw 300 to drive the telescopic rod 200 to rise and fall, the telescopic rod 200 can only slide linearly along the groove 110 due to the cooperation of the slider 210 and the groove 110, and will not rotate within the sleeve 100.

[0045] In this application, three sliding grooves 110 are provided on the sleeve 100, and the three sliding grooves 110 are arranged at equal intervals on the sleeve wall of the sleeve 100. Correspondingly, three sliders 210 are also provided at equal intervals on the outer wall of the telescopic rod 200.

[0046] To ensure that the sliding sleeve 510 slides linearly on the sleeve 100, in some embodiments, a guide rail 220 is provided on the wall of the sleeve 100. The guide rail 220 extends along the length of the sleeve 100, with one end extending to a certain distance from the fixed plate 540 and the other end extending to a certain distance from the end of the sleeve 100. The inner wall of the sliding sleeve 510 is provided with a guide groove 511 that matches the guide rail 220. During the sliding process on the outer wall of the sleeve 100, the sliding sleeve 510 can only maintain linear movement along the guide rail 220 with the cooperation of the guide rail 220 and the guide groove 511, avoiding the problem of rotation relative to the sleeve 100.

[0047] In this application, the inner wall of the sliding sleeve 510 is provided with three guide grooves 511 at equal intervals, and the outer wall of the sleeve 100 is provided with three guide rails 220 at equal intervals.

[0048] To make the support rod 530 more stable on the ground, in some embodiments, a support plate 600 is provided at the end of the support rod 530 that supports the ground, and the support plate 600 is hinged to the support rod 530. The support rod 530 has a larger contact area with the ground, resulting in more stable support. Furthermore, when the device needs to be stored, the support rod 530 can be rotated so that it is parallel and close to the ground, thus reducing the space occupied.

[0049] In other embodiments, the support plate 600 is provided with a first magnetic adsorption element 610, and the support rod 530 is provided with a second magnetic adsorption element 531 on the side near one end of the support plate 600. When the support plate 600 rotates to abut against the side of the support rod 530, the first magnetic adsorption element 610 and the second magnetic adsorption element 531 can attract each other. After the support plate 600 rotates to abut against the support rod 530, the attraction between the first magnetic adsorption element 610 and the second magnetic adsorption element 531 can keep the support plate 600 in position.

[0050] In some embodiments, a positioning pin 700 is provided on the sliding sleeve 510, and a support state positioning groove 120 and a retracted state positioning groove 130 are formed on the outer wall of the sleeve 100. An assembly hole is formed on the sliding sleeve 510 that penetrates its side wall. The positioning pin 700 is fitted in the assembly hole. One end of the positioning pin 700 is located outside the sliding sleeve 510, and the other end is located inside the sliding sleeve 510. The positioning pin 700 can move radially and retractably along the sliding sleeve 510. The end of the positioning pin 700 located inside the sliding sleeve 510 is used to insert into the support state positioning groove 120 or the retracted state positioning groove 130.

[0051] When the support rod 530 is needed to support the device, slide the sleeve 510 to the support state positioning groove 120, and then insert the positioning pin 700 into the support state positioning groove 120, so that the sleeve 510 is positioned in the support state positioning groove 120, ensuring that each support rod 530 is stably supported. When the support rod 530 needs to be retracted, slide the sleeve 510 to the retracted state positioning groove 130, and then insert the positioning pin 700 into the retracted state positioning groove 130, so that the sleeve 510 is positioned in the retracted state positioning groove 130, so that each support rod 530 remains stable in the retracted state.

[0052] In some embodiments, a connecting seat 800 is provided on the outer wall of the sliding sleeve 510 at the position corresponding to the assembly hole. A through hole is provided on the connecting seat 800, and the through hole is aligned with the assembly hole. A positioning pin 700 passes through the through hole and the assembly hole. A baffle 710 is provided at one end of the positioning pin 700 outside the sliding sleeve 510. An elastic member 720 is provided between the baffle 710 and the connecting seat 800. The elastic member 720 is sleeved on the positioning pin 700. One end of the elastic member 720 is fixedly connected to the baffle 710, and the other end is fixedly connected to the connecting seat 800.

[0053] Specifically, the elastic component 720 is a columnar spring. The elastic component 720 applies a force to the positioning pin 700, making the positioning pin 700 more secure when inserted into the positioning groove 120 in the supported state or the positioning groove 130 in the retracted state.
