[0044] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0045] like Figure 2 As shown, it includes a vertically arranged support tube 10, wherein the outer wall of the support tube 10 is fixedly connected to a support seat 102 by bolts, the outer side of the support tube 10 is sleeved with a sleeve 1, and the signpost 100 is fixedly installed on the sleeve 1, wherein the support seat 102 is located at the bottom of the support tube 10, and the sleeve 1 is rotatably connected to the support seat 102. Specifically, as shown in FIG. Figure 3 As shown, a support ring groove 1021 is provided on the support seat 102 , and the bottom of the sleeve 1 is inserted into the support ring groove 1021 . A driving mechanism 8 for driving the sleeve 1 to rotate is also provided in the support tube 10 .

[0046] Specifically, such as Figure 3 and Figure 4As shown, the driving mechanism 8 includes a gear 81 partially extending out of the outer wall of the support tube 10, and a ring gear 82 is fixedly connected to the inner wall of the sleeve 1. When the sleeve 1 is sleeved on the support tube 10, the ring gear 82 and the gear 81 are engaged with each other. The driving mechanism 8 also includes a motor, which is connected to the gear 81 by power. The gear 81 can drive the ring gear 82 to rotate, and then the sleeve 1 can be driven to rotate on the support seat 102 through the ring gear 82 to adjust the angle of the signpost 100 on the sleeve 1.

[0047] It is worth mentioning that the motor here is a driving source, which is well known to those skilled in the art. Therefore, the structure of the motor and the installation method of the motor are no longer shown in the accompanying drawings.

[0048] Under normal circumstances, the power of the signpost 100 is supplied through a cable. When the driving mechanism 8 drives the sleeve 1 to rotate, thereby adjusting the angle of the signpost 100, the cable will twist. When the angle of rotation of the sleeve 1 is too large, the cable will break. At the same time, the continued rotation of the sleeve 1 will be restricted, causing the sleeve 1 to be stuck on the support seat 102.

[0049] In order to solve the above problem, in this embodiment, Figure 3 and Figure 5 As shown, a conductive ring 41 is fixedly mounted on the sleeve 1, and a conductive brush 42 is provided on the inner wall of the sleeve 1, wherein the conductive brush 42 and the conductive ring 41 are electrically connected, thereby being able to conduct electricity on the support tube 10 to the sleeve 1, solving the problem of cable torsion.

[0050] Among them, the outer wall of the sleeve 1 is provided with a mounting seat 2, and the road sign 100 is fixedly installed on the mounting seat 2. Specifically, the mounting seat 2 is provided with a power supply connector 3 electrically connected to the conductive brush 42, such as Figure 4 As shown, the signpost 100 is provided with a plug 101 electrically connected to the power supply connector 3 .

[0051] It is worth noting here that the plug 101 is electrically connected to the signpost 100. After the power on the conductive ring 41 is transferred to the power supply connector 3 through the conductive brush 42, the plug 101 is used to transmit the power to the signpost 100 again, thereby supplying power to the signpost 100.

[0052] During road marking, the support tube 10 is not equipped with just one signpost 100. Usually, there are three pairs of signposts 100. When the power of the conductive ring 41 is transmitted to the signpost 100 on the sleeve 1, the conductive brush 42 must contact the corresponding conductive ring 41. If the conductive brush 42 is directly fixed on the inner wall of the sleeve 1, the power connection end of the conductive brush 42 needs to extend beyond the gear ring 82. Then, when the sleeve 1 is installed, the conductive brush 42 on the sleeve 1 is likely to contact the top gear 81 or the conductive ring 41, affecting the installation of multiple sleeves 1.

[0053] Therefore, in this embodiment, in order to be able to set multiple sets of sleeves 1 in the axial direction of the support tube 10, the conductive brush 42 is slidably connected to the sleeve 1, such as Figure 5 and Figure 6 As shown, the conductive brush 42 is slidably installed in the power supply connector 3, and also includes an adjustment mechanism 5 for switching the conductive brush 42 between a first state and a second state. Specifically, in the first state, the conductive brush 42 contacts the conductive ring 41 to achieve circuit connectivity. In the second state, the conductive brush 42 is separated from the conductive ring 41 to disconnect the circuit. At this time, the problem of the conductive brush 42 touching the gear 81 or the conductive ring 41 during installation is solved. When the sleeve 1 is installed to the specified position, the adjustment mechanism 5 is used to switch the conductive brush 42 to the first state to achieve contact between the conductive ring 41 and the conductive brush 42, thereby achieving circuit connectivity.

[0054] Specifically, such as Figure 6 and Figure 8 As shown, a sliding groove 32 is provided inside the power supply connector 3, wherein the opening of the sliding groove 32 faces the side of the conductive ring 41, and the side wall of the conductive brush 42 is slidingly connected to the inner wall of the sliding groove 32. The adjustment mechanism 5 includes an adjusting bolt 51, wherein the adjusting bolt 51 is rotatably connected to the power supply connector 3, and a threaded hole 421 is provided in the conductive brush 42, and the adjusting bolt 51 is threadedly connected to the threaded hole 421.

[0055] Through the above arrangement, before the sleeve 1 is installed in the support tube 10, the conductive brush 42 is adjusted to the second state by using the adjusting bolt 51, so that the conductive brush 42 is received in the sliding groove 32, thereby preventing the conductive brush 42 from interfering with the installation of the sleeve 1. After the sleeve 1 is installed in the corresponding position, the conductive brush 42 is adjusted to the first state by using the adjusting bolt 51. At this time, the conductive brush 42 moves out of the sliding groove 32 and contacts the conductive ring 41, thereby realizing circuit connectivity.

[0056] In order to realize the installation of the signpost 100, in this embodiment, as shown in FIG. Figure 4 and Figure 5As shown, the mounting seat 2 is provided with an upward-opening mounting groove 21, wherein the longitudinal section of the mounting groove 21 is U-shaped, the power supply connector 3 is installed in the mounting groove 21, and the side wall of the mounting groove 21 is provided with a plug-in rib 24 extending vertically upward, and the side wall of the signpost 100 is provided with a plug-in groove 103 for inserting the plug-in rib 24. When installing the signpost 100, align the plug-in rib 24 with the plug-in groove 103, and then insert the signpost 100 from top to bottom into the mounting groove 21, and then use the blocking cover 6 to encapsulate the end part of the signpost 100 in the mounting groove 21 to achieve the installation of the signpost 100.

[0057] It is worth mentioning here that Figure 6 and Figure 7 As shown, the bottom wall of the blocking cover 6 is provided with a blocking rib 62 extending vertically downward. After the blocking cover 6 is installed on the mounting seat 2, the blocking rib 62 of the blocking cover 6 abuts against the top wall of the signpost 100, thereby preventing external rainwater from flowing into the mounting groove 21 from the gap between the signpost 100 and the mounting groove 21, thereby reducing the risk of short circuit between the plug 101 and the power supply connector 3.

[0058] The arrangement of the plug-in ribs 24 and the plug-in grooves 103 here can not only realize the precise installation of the signpost 100, but also block the path of external rainwater entering the installation groove 21 along the gap between the side wall of the signpost 100 and the installation groove 21, thereby improving the barrier effect of external rainwater.

[0059] Specifically, in this embodiment, Figure 4 、 Figure 5 and Figure 6 As shown, the side wall of the mounting groove 21 is provided with a connecting sheet metal 22. After the blocking cover plate 6 is covered on the mounting seat 2, the bolt 61 passes through the blocking cover plate 6 and is threadedly connected to the connecting sheet metal 22, thereby fixing the blocking cover plate 6 on the mounting seat 2.

[0060] Since the blocking cover 6 and the mounting seat 2 are detachably connected by bolts 61 , a gap will be left between the blocking cover 6 and the outer wall of the sleeve 1 , and rainwater from the outside can penetrate into the mounting groove 21 through the gap between the blocking cover 6 and the sleeve 1 .

[0061] To solve the above problem, in this embodiment, Figure 5 and Figure 6As shown, a partition plate 23 is provided inside the mounting groove 21, which is vertically arranged upward and divides the inner cavity of the mounting groove 21 into a mounting cavity 211 and a drainage cavity 212, wherein the drainage cavity 212 is closer to the outer wall of the sleeve 1 than the mounting cavity 211, and a first through-hole 231 is provided on the partition plate 23, and a second through-hole 2122 opposite to the first through-hole 231 is provided on the inner wall of the drainage cavity 212, and a limiting rib 31 is provided on the outer wall of the power supply connector 3, wherein the outer diameter of the limiting rib 31 is smaller than the inner diameter of the first through-hole 231, and the outer diameter of the limiting rib 31 is larger than the inner diameter of the first through-hole 231. The inner diameter of the second through-hole 2122, during the installation process of the power supply connector 3, is inserted from the side of the installation cavity 211 into the drainage cavity 212, wherein the limiting rib 31 passes through the first through-hole 231 and enters the drainage cavity 212. Finally, the limiting rib 31 abuts against the inner wall of the drainage cavity 212 and blocks the second through-hole 2122; specifically, the power supply connector 3 passes through the drainage cavity 212, one end of the power supply connector 3 is located in the installation cavity 211, and the other end extends out of the mounting seat 2 and is located on the side of the inner wall of the sleeve 1, and the bottom wall of the drainage cavity 212 is provided with a guide hole 2121.

[0062] It also includes an inverted U-shaped blocking plate 7. After the power supply connector 3 is inserted into the drainage cavity 212, the blocking plate 7 is inserted between the limiting edge 31 and the partition plate 23. The side walls of the blocking plate 7 are respectively in contact with the side walls of the partition plate 23 and the side walls of the limiting edge 31. The blocking plate 7 blocks the first through-hole 231, which can prevent water in the drainage cavity 212 from entering the installation cavity 211 through the first through-hole 231, thereby enhancing the sealing of the installation cavity 211.

[0063] Specifically, such as Figure 6 and Figure 7 As shown, the bottom wall of the blocking cover plate 6 is further provided with a guide rib 63 which is plugged into the drainage cavity 212 .

[0064] Through the above arrangement, when rainwater appears on the blocking cover 6, the rainwater will flow into the drainage chamber 212 along the guide rib 63. Since the blocking plate 7 blocks the first perforation 231 and the limiting rib 31 blocks the second perforation 2122, the rainwater in the drainage chamber 212 will flow downward through the guide hole 2121, preventing rainwater from accumulating in the drainage chamber 212, thereby improving the safety of the connection between the plug 101 and the power connector 3.

For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved.
