Description

Technical Field

[0001] The present disclosure relates to the field of road signs, and in particular to a road sign angle adjustment mechanism. Background Art

[0002] Signposts are usually used at traffic intersections or inside scenic spots to guide pedestrians or tourists in the direction of travel.

[0003] Typically, a signpost is directly mounted on a pole through a clamp. After the signpost is installed, its angle cannot be moved. Furthermore, the information provided on the signpost is single and cannot meet the needs of tourists or pedestrians.

[0004] At present, a smart road sign includes multiple signboards that can receive destination information, as well as an interactive panel. Through human-computer interaction, the destination is uploaded and the destination information is then displayed on the signboard. At the same time, the signboard is rotated to the appropriate direction through a driving mechanism to guide pedestrians or tourists.

[0005] Among them, multiple groups of signboards are usually set on smart road signs. The driving mechanism can randomly switch power to one of the signboards to realize the rotation of the corresponding signboard. At the same time, the power transmission of the remaining signboards is disconnected from the driving mechanism. Here, the remaining signboards can rotate arbitrarily under the interference of strong winds, which can easily cause damage to the signboards.

[0006] Therefore, it is necessary to design a signpost angle adjustment mechanism to solve the problem that the signpost can be rotated at will when not in use. Utility Model Content

[0045] 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.

[0046] like Figure 1 and Figure 3 As shown, it includes a body 1, wherein a support tube 10 extending vertically upward is fixedly provided on the body 1, wherein the outer wall of the support tube 10 is rotatably connected to a sleeve 21, and the indicator sign 2 is fixedly installed on the sleeve 21, and also includes a driving mechanism 3 for driving the sleeve 21 to rotate around the axis of the support tube 10.

[0047] Specifically, the body 1 is further provided with an interactive panel and a central control unit, and the driving mechanism 3 and the interactive panel are electrically connected to the central control unit.

[0048] Through the above-mentioned setting, tourists or pedestrians input the destination on the interactive panel. After receiving the destination information, the central control unit processes the information and then transmits the guidance information to the destination to the signboard 2 for loop playback. At the same time, the driving mechanism 3 is used to change the direction of the signboard 2 so that the direction of the signboard 2 is consistent with the direction of the destination, thereby guiding the tourists.

[0049] In this embodiment, if Figure 2 and Figure 3 As shown, three groups of indicator signs 2 are provided and arranged along the axial direction of the support tube 10 , and two adjacent groups of indicator signs 2 are rotatably connected through the sleeve 21 .

[0050] In order to install the sleeve 21, in this embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, it includes a support seat 5, which is sleeved on the outside of the support tube 10 and fixed on the support tube 10 by screws. The upper end of the support seat 5 is provided with a support ring groove 51, and the bottom of the lowest sleeve 21 is inserted into the support ring groove 51 to realize the rotational connection between the sleeve 21 and the support ring groove 51, and the support seat 5 is used to support the sleeve 21.

[0051] Specifically, in order to realize the rotation connection between the sleeves 21 and the sleeves 21, in this embodiment, as shown in FIG. Figure 3 As shown, a plug-in portion 211 is provided at the bottom of the sleeve 21, and a supporting ring groove 212 is provided at the top of the sleeve 21. When the three groups of sleeves 21 are installed axially along the support tube 10, the plug-in portion 211 at the bottom of the sleeve 21 is inserted into the supporting ring groove 212 at the top of the lower sleeve 21, wherein the plug-in portion 211 is rotatably connected to the supporting ring groove 212.

[0052] In order to prevent rainwater from flowing back from the top sleeve 21, in this embodiment, Figure 3 As shown, an end cover 6 is installed on the top of the support tube 10 , wherein the lower edge of the end cover 6 is inserted into the supporting ring groove 212 of the uppermost sleeve 21 , thereby sealing the opening at the top of the sleeve 21 .

[0053] In order to prevent rainwater from accumulating in the supporting ring groove 212, in this embodiment, Figure 3 As shown, the bottom walls of the supporting ring groove 212 and the supporting ring groove 51 are both provided with a guide hole 7 extending radially outward along the support tube 10. When rainwater enters the supporting ring groove 212 or the supporting ring groove 51 along the outer wall of the sleeve 21, the rainwater will flow out along the guide hole 7.

[0054] In order to realize the rotation of the sleeve 21, in this embodiment, as shown in FIG. Figure 3 、 Figure 5 and Figure 6As shown, a gear ring 22 is fixedly provided on the inner wall of the sleeve 21, an avoidance opening 101 is provided on the peripheral wall of the support tube 10, and a supporting seat 102 is provided on the inner wall of the support tube 10. The supporting seat 102 is rotatably connected to a transmission gear 8 that can extend to the outside of the support tube 10 through the avoidance opening 101 via a rotating shaft, wherein the transmission gear 8 and the gear ring 22 are engaged with each other.

[0055] In order to enable the ring gear 22 to rotate stably, in this embodiment, as shown in FIG. Figure 5 As shown, three groups of avoidance openings 101 are provided on the same horizontal plane, wherein the avoidance openings 101 are evenly distributed along the circumference of the support tube 10, and three groups of transmission gears 8 are provided and extend outward from the corresponding avoidance openings 101, while meshing with the ring gear 22 to improve the rotation stability of the ring gear 22.

[0056] Specifically, such as Figure 3 、 Figure 4 and Figure 6 As shown, the driving mechanism 3 includes a motor 31, a driving shaft 32 and spline teeth 33, wherein the motor 31 is fixedly mounted on the body 1, the driving shaft 32 is arranged in the inner cavity of the support tube 10 and is arranged along the axial direction of the support tube 10, the driving shaft 32 is fixedly connected to the output shaft of the motor 31, and three groups of spline teeth 33 are provided and mounted on the driving shaft 32, each group of spline teeth 33 corresponds to a group of sleeves 21, and also includes a switching component 4, wherein the switching component 4 switches between a first state and a second state, and the first state, as shown in FIG. Figure 7 As shown, at this time, the switching assembly 4 is located between the transmission gear 8 and the spline teeth 33, and the power of the drive shaft 32 is transmitted to the transmission gear 8. In the second state, as shown in FIG. Figure 8 As shown, at this time, the switching assembly 4 disconnects the transmission between the transmission gear 8 and the spline teeth 33 , and uses the switching assembly 4 to lock the ring gear 22 and the support tube 10 to limit the rotation of the ring gear 22 .

[0057] Specifically, such as Figure 6 As shown, the switching assembly 4 includes an electric push rod 41, a switching gear 42 and a positioning ring gear 43, wherein a positioning seat 103 is provided on the inner wall of the support tube 10, the positioning ring gear 43 is fixedly mounted on the positioning seat 103, the electric push rod 41 is fixedly mounted on the positioning seat 103, and the switching gear 42 is rotatably connected to the output end of the electric push rod 41. In the first state, the switching gear 42 is engaged with the transmission gear 8 and the spline teeth 33 at the same time, and the switching gear 42 is disengaged from the positioning ring gear 43. Therefore, when the drive shaft 32 rotates, the spline teeth 33 can drive the switching gear 42 to rotate around the output end of the electric push rod 41. At this time, the switching gear 42 drives the transmission gear 8 to rotate, and then can drive the sleeve 21 to rotate through the ring gear 22, so that the angle of the indicator sign 2 changes.

[0058] When the switching gear 42 is in the second state, as shown in FIG. Figure 8 As shown, at this time, the switching gear 42 is engaged with the transmission gear 8 and the positioning ring gear 43 at the same time, and the switching gear 42 is disengaged from the spline teeth 33. At this time, the drive shaft 32 cannot transmit power to the transmission gear 8 through the switching gear 42. At the same time, since the switching gear 42 and the positioning ring gear 43 are engaged with each other, the positioning ring gear 43 is fixed on the support tube 10, thereby making the switching gear 42 unable to rotate. Even if the indicator sign 2 tends to rotate due to bad weather outside, it will be stopped by the switching gear 42, thereby achieving the locking of the indicator sign 2.

[0059] In this embodiment, three sets of switching assemblies 4 are provided, and each set of switching assemblies 4 is adapted to a set of sleeves 21. When the corresponding indicator sign 2 needs to be adjusted in angle, the corresponding switching assembly 4 is switched to the first state, and the remaining two switching assemblies 4 are switched to the second state, restricting the rotation of the other two indicator signs 2. Alternatively, all three sets of switching assemblies 4 can be switched to the first state, achieving simultaneous rotation of the indicator signs 2.

[0060] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. 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 application can be achieved.
