Description

Technical Field

[0001] The invention relates to the technical field of indication signs, and in particular to a rotatable and foldable wind-resistant indication sign. Background Art

[0002] This application is a divisional application of application number "2022113426632", application date October 31, 2022, and invention name "Rotatable wind-resistant indicating device".

[0003] With the development of technology, scenic spot signage has also undergone some changes, from traditional fixed signage to signage with rotating and electronic display functions. This type of signage is usually used in conjunction with a smart guide screen. When using it, tourists only need to click on the destination on the guide screen, and the corresponding signage will display the destination clicked by the user and rotate to the corresponding direction. This type of signage is more intelligent, has a strong sense of technology, and has a good user experience, and can be used by multiple people at the same time.

[0004] The above-mentioned signboard with rotation and display functions integrates a liquid crystal display function and a rotating structure, so the structure is more complicated than that of traditional signboards. On the other hand, since this type of display sign usually has multiple sign bodies, that is, there are usually multiple signs on the same column, its windward area is also larger. In order to ensure the strength of the sign, the strength of the column must be increased. Then, since the sign body integrates a display function and a rotating structure, it is best to reduce its windward area in windy weather. In response to this problem, the existing patent number "2021101304339" records that the sign is rotated to a horizontal state to reduce the windward area of ​​the sign, but the sign recorded in the patent does not have the ability to rotate around the column, and since the transmission rod that controls the sign is directly inserted into the interior of the column, it is also impossible to directly install the existing transmission structure on the column to drive the sign in the patent to rotate around the column as the axis.

[0005] Obviously, the signboard that can be rotated to a horizontal state in the above-mentioned prior art (patent number 2021101304339) cannot be combined with the signboard with rotation and display functions in the prior art. Summary of the invention

DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0040] Embodiment 1:

[0041] like Figures 1 to 4As shown: This embodiment discloses a rotatable and foldable wind-resistant sign: it includes a column 1, a rotating sleeve 2 and a sign body 3. The rotating sleeve 2 is sleeved on the column 1 and can rotate around the column 1. The end of the sign body 3 is connected to the rotating sleeve 2 through a central axis 31. The sign body 3 can be rotated to a horizontal state relative to the rotating sleeve 2. The sign body 3 is in a vertical state during normal indication, but can also be rotated 90 degrees to a horizontal state ( Figure 4 As shown in the figure), in the horizontal state, its windward area is greatly reduced, which can improve the wind resistance.

[0042] This embodiment is particularly suitable for indicating signs with multiple sign bodies 3, so there are multiple rotating sleeves 2, and the multiple rotating sleeves 2 are sequentially stacked along the column 1, and all the rotating sleeves 2 can rotate independently with the column 1 as the axis. The outside of the column 1 is provided with multiple bosses 11 for supporting the rotating sleeves 2. In order to ensure the appearance, the outer diameter of the bosses 11 is usually equal to the outer diameter of the rotating sleeve 2.

[0043] Specifically: the rotating sleeve 2 is provided with a rotating sleeve gear ring 23, and the rotating sleeve gear ring 23 is driven by a gear 4 installed on a motor 41, and the motor 41 is fixed inside the column 1. The side of the rotating sleeve 2 is provided with a sleeve 21 whose axis is perpendicular to the axis of the rotating sleeve 2, and the central shaft 31 is rotatably connected to the sleeve 21. The central shaft 31 is provided with a sign gear 312 coaxially arranged and located outside the rotating sleeve 2 with an arc of 90°. The column 1 is provided with an arc-shaped rack 12 with a tooth surface facing upward or downward. Usually, the arc-shaped rack 12 is fixed to the boss 11, and it is preferably designed with the tooth surface facing upward.

[0044] The sleeve 21 is provided with an arc groove 22 , and the position of the sign gear 1 312 matches the arc groove 22 , that is, when the rotating sleeve 2 rotates to the point where the sign gear 1 312 meshes with the arc rack 12 , the arc rack 12 passes through the arc groove 22 and matches with the sign gear 1 312 .

[0045] When the sign body 3 is working normally, it needs to be in a normal vertical state, so it is necessary to design a positioning mechanism between the central axis 31 and the sleeve 21. The positioning structure of this embodiment is as follows: the outer surface of the central axis 31 is provided with a positioning groove 311, and the positioning groove 311 is distributed along the circumference of the outer surface of the central axis 31. Its arc is usually 90 degrees, and the depth is usually deeper and the width is larger at both ends. The sleeve 21 cooperates with the positioning groove 311 through the steel ball top screw 27. When the sign body 3 is in the indicating state or the horizontal state, the steel ball top screw 27 is located at a deeper position at the end of the positioning groove 311 to achieve positioning. The steel ball top screw 27 in this embodiment belongs to the prior art, including a top screw arranged on the outside, a spring and a steel ball arranged inside the top screw, and the spring drives the steel ball to be elastically connected to the inside of the positioning groove 311.

[0046] The end of the central shaft 31 is also provided with a limit ring 313, which is used to prevent the central shaft 31 from being separated from the sleeve 21. The limit ring 313 and the central shaft 31 are usually connected in a detachable manner, for example, a commonly used external retaining spring can be used. Furthermore, the central axis of the central shaft 31 can also have a central hole at the axial position, which is used for the cables inside the column 1 to pass through the sign body 3 to realize the power supply of the sign body 3.

[0047] When the rotating sleeve 2 rotates until the sign gear 1 312 is meshed with the arc rack 12, the arc rack 12 can drive the sign body 3 to rotate to a horizontal state with the central axis 31 as the axis. When the rotating sleeve 2 rotates until the sign gear 1 312 is disengaged from the arc rack 12, the arc rack 12 can drive the sign body 3 to rotate to an indicating state with the central axis 31 as the axis.

[0048] It can be seen from the above description that when the rotating sleeve 2 is rotating normally, the sign gear 1 312 cannot contact the arc rack 12, and the arc rack 12 only needs to be able to drive the sign gear 1 312 to rotate 90 degrees, so its arc does not need to be very large (depending on the diameter of the column), usually 1 / 12π to 1 / 6π degrees, so the rotation angle of the rotating sleeve 2 relative to the column 1 can usually reach 5 / 6π to 11 / 12π, and this embodiment has multiple sign bodies 3, so 360-degree indication without dead angles can be achieved. In actual application, multiple arc racks 12 are preferably evenly distributed along the column 1.

[0049] In this embodiment, the cable can pass through the column 1 from the bottom to the top, and then pass through the side of the column 1 above or below the corresponding rotating sleeve 2 to connect with the sign body 3. Therefore, in order to ensure the appearance, a sheath is usually provided on the outside of the column 1, and the user covers the gear 1 4, the rotating sleeve gear ring 23, the arc-shaped rack 12 and the above-mentioned cables.

[0050] Generally, scenic spot signs are divided into eight directions: east, southeast, south, southwest, west, northwest, north, and northeast. In this embodiment, there are four sign bodies 3 (attached Figure 1Only three of the sign bodies are shown in the figure. The flip positions of the four sign bodies 3 (the positions of the arc-shaped racks 12) are evenly distributed with the column 1 as the center. Each sign body 3 can rotate under the drive of the motor 141 and the gear 14. Through the circumference ratio of the gear 14 and the rotating sleeve gear ring 23, the relationship between the rotation angle of the sign body 3 along the column 1 and the number of turns that the motor 141 needs to rotate can be calculated to ensure the correct indication of the sign body 3. Assume that the lowest sign body 3 is in a horizontal state (i.e., a windproof state) when pointing to the east, that is, the lowest sign body 3 cannot indicate in the east direction. At this time, the arc-shaped rack 12 corresponding to the lowest sign body 3 is set at the position between the northeast direction and the east direction of the column 1. When the lowest sign body 3 rotates from the northeast direction to the east direction, it completes a 90° rotation. The other three sign bodies 3 from bottom to top are in a horizontal state when pointing to the south, west, and north directions, respectively, and the positions of the corresponding arc-shaped racks 12 are also adjusted accordingly. That is to say, when the four sign bodies 3 are in a windproof state, they are in a circumferential direction centered on the column 1, so that when the sign bodies 3 are in a display state, the four sign bodies 3 can also cover all indication directions 360 degrees.

[0051] When tourists operate the guide screen to rotate to the desired destination, if the selected destination is in the east, south, west or north direction, any one of the three sign bodies 3 with indication working status in the direction is controlled to indicate, and the sign body can be lit to remind tourists, and the lower sign body 3 is preferentially selected for indication, which is convenient for tourists to observe. When tourists select destinations in multiple directions, they can select the appropriate sign body 3 to rotate the angle and light it up to indicate tourists.

[0052] When the sign body 3 is in the indicating state, it is still assumed that the lowest sign body 3 is in a horizontal state (i.e., a windproof state) when pointing to the east. Then, the sign body 3 can only rotate in a clockwise direction from east to northeast, or in a counterclockwise direction from northeast to east, through the control of motor 1 41. That is, unless there are special circumstances such as strong winds, the sign body 3 will not be in a horizontal state.

[0053] When encountering strong wind weather, when the wind direction sensor on the column detects that the wind force reaches the set value, each sign body 3 is driven to rotate to a horizontal state through a motor 41 and a gear 4, and then returns to the indicating state after the strong wind passes.

[0054] Embodiment 2:

[0055] Compared with the first embodiment, the sign body 3 of this embodiment is folded to achieve the effect of reducing the windward area. Figures 5 to 8As shown: the central shaft 31 is fixedly connected to the side of the rotating sleeve 2 (non-rotatable) as the rotation axis of the sign body 3. A turbine 24 is provided at the end of the central shaft 31, and the turbine 24 is engaged with the worm 5 installed on the sign body 3. The worm 5 is driven by a worm motor 51 installed on the sign body 3, so that when the worm motor 51 rotates, the rotation drive of the sign body 3 can be achieved through the torque generated by the turbine and worm. A wire hole 241 is also provided at the axis of the central shaft 31 and the turbine 24 for the wire to pass through. It is best to use a smaller motor for the worm motor 51, which is protected by a protective cover 32 on the outside. Since the worm gear transmission has self-locking properties, the worm motor 51 does not need to be kept in the energized state at all times when the sign body 3 is in the normal indication state.

[0056] Since the present embodiment adopts a folding method to reduce the windward area of ​​the sign body 3, the cross section of the column 1 of the present embodiment is preferably rectangular, so that the fit between the sign body 3 and the column 1 can be improved. Considering the installation and rotation of the rotating sleeve 2, the column 1 of the present embodiment includes a rectangular section with a rectangular cross section and a circular section with a circular cross section. The rotating sleeve 2 is sleeved on the circular section, and the circular section is provided with a column gear ring 13. The column gear ring 13 can play the role of limiting the rotating sleeve 2 by the boss 11 in the first embodiment. The axial position of the rotating sleeve 2 relative to the column 1 is limited by the column gear ring 13. The rotating sleeve 2 is rotated by the transmission cooperation between the gear 14 and the column gear ring 13. When the gear 14 rotates, the gear 14 rotates with the column gear ring 13 as the center, and then drives the rotating sleeve 2 to rotate relative to the column 1.

[0057] like Figure 6 and Figure 7 As shown: the rotating sleeve 2 includes a circular sleeve arranged inside and matching the circular segment, and a rectangular sleeve arranged outside and matching the rectangular segment. The circular sleeve and the rectangular sleeve are connected by vertical ribs, so that the rotating sleeve 2 forms a fixed profile, which is easy to produce and manufacture.

[0058] A cavity 25 located inside the four corners of the rectangular sleeve is provided between the rectangular sleeve and the circular sleeve. The gear 4 is driven by a motor 41 provided inside the cavity 25. As shown in the figure, a circuit board 251 and a battery 252 can also be installed inside the cavity 25 if necessary.

[0059] When in a strong wind environment, the worm motor 51 rotates, and the cooperation of the worm and worm gear can make the sign body 3 rotate downward. Since the cross section of the column 1 is also rectangular, the sign body 3 after folding downward can be in a state of being in contact and overlapping with the column 1. It should be noted that since the outer contour cross section of the rotating sleeve 2 and the outer contour cross section of the column 1 are both square, when the sign body 3 is in the storage state, the rotating sleeve 2 and the column 1 are preferably in a state of being parallel to each other. Figure 8Compared with the first embodiment, the windproof effect of this embodiment is better and the appearance is more beautiful.

[0060] In this embodiment, the cable of the sign body 3 preferably uses an electric slip ring in the prior art to connect the internal electrical signal of the column 1 with the sign body 3. The specific connection method can be configured by those skilled in the art according to actual conditions.

[0061] Embodiment three:

[0062] like Figures 9 to 11 As shown: This embodiment is similar to the first embodiment, the side of the rotating sleeve 2 is provided with a sleeve 21 whose axis is perpendicular to the axis of the rotating sleeve 2, and the central shaft 31 is rotatably connected to the sleeve 21. A collar 6 with a diameter larger than that of the column 1 is provided on the outer surface of the column 1, the rotating sleeve 2 is sleeved on the collar 6, and both the upper and lower ends are provided with inner flanges 26 that match the ends of the collar 6, and the rotating sleeve gear ring 23 is arranged on the inner edge of the inner flange 26. That is to say, the inner flange 26 is equivalent to the inner limit structure of the rotating sleeve 2, which is used to prevent the rotating sleeve 2 from moving up and down relative to the column 1, and plays the role of the boss 11 in the first embodiment.

[0063] Two horizontal annular grooves 1 61 are provided on the side of the collar 6, and a horizontal annular groove 2 63 is provided in the middle of the two horizontal annular grooves 1 61, which is staggered with the horizontal annular groove 1 61 in the circumferential direction. The two horizontal annular grooves 1 61 are connected to the same end of the horizontal annular groove 2 62 through the oblique annular groove 62, and the two ends of the oblique annular groove 62 are connected to the horizontal annular groove 1 61 and the horizontal annular groove 2 63 in a smooth transition manner. Two guide pins 33 are provided at the end of the central shaft 31, and the distribution direction of the two guide pins 33 is consistent with the width direction of the sign body 3.

[0064] The outer diameter of the guide pin 33 matches the above-mentioned annular grooves (horizontal annular groove 1 61, oblique annular groove 62 and horizontal annular groove 2 63), and can slide in the annular grooves. Furthermore, a rotatable rotating ring (such as a nylon sleeve) can be provided on the outer side of the guide pin 33 to convert sliding friction into rolling friction. When the sign body 3 is in the indicating state, the guide pins 33 are respectively located inside the two horizontal annular grooves 1 61, that is, the two guide pins 33 are distributed up and down, so as to ensure that the sign body 3 is in the display state.

[0065] When the rotating sleeve 2 rotates until the guide pin 33 enters the oblique annular groove 62, the distance between the two guide pins 33 in the vertical position becomes smaller, and the sign body 3 rotates around the central axis 31. When the two guide pins 33 successively enter the interior of the horizontal annular groove 63, the sign body 3 enters the storage state.

[0066] It should be noted that: in the process of the guide pin 33 entering from the horizontal annular groove 61 to the oblique annular groove 62, it is possible (theoretically possible) that the two guide pins 33 are squeezed at the junction of the horizontal annular groove 61 and the oblique annular groove 62 at the same time. Fig.12 As shown: the upper and lower intersections can be staggered in the circumferential direction. Fig.12 D in is not zero, and when the rotating sleeve 2 rotates, one of the guide pins 33 can enter the interior of the oblique annular groove 62 first.

[0067] There are also steel ball screws 27 and positioning grooves 311 between the sleeve 21 and the central axis 31 , which are the same as those in the first embodiment, for ensuring the stability of the sign body 3 .

[0068] In addition, in order to prevent the two guide pins 33 from sliding out of the horizontal ring groove 63 and entering the same oblique ring groove 62, a torsion spring (not shown in the figure) is provided between the sleeve 21 and the center shaft 31 for driving the center shaft 31 to rotate relative to the sleeve 21. Due to the presence of the torsion spring, the center shaft 31 has a certain elastic torque relative to the sleeve 21, which prevents the two guide pins 33 from entering the same oblique ring groove 62 at the same time, thereby ensuring the normal rotation of the sign body 3 when it is reset from the horizontal state to the indicating state.

[0069] When in use, the user inputs the target scenic spot, and the system displays the target scenic spot on the sign body 3, and under the action of the motor 1 41, drives the sign body 3 to rotate to the corresponding indication angle with the column 1 as the axis. In addition, the display area of ​​the sign body 3 can also display information such as the distance, walking time, and traffic mode of the target scenic spot, which is particularly suitable for application scenarios with many forks in the road. When no user is using it, multiple sign bodies 3 can also be rotated to the same plane, so that multiple sign bodies 3 can form a whole display area for broadcasting scenic spot information, thereby enhancing the sense of technology, playability and user experience.

[0070] When the external wind force reaches a certain value, the sign body 3 can be rotated to a horizontal state (Example 1, Example 3) or a folded state (Example 2), so as to reduce the windward area of ​​the entire sign, reduce the thrust of the wind on the sign, and prevent the sign body 3 from being subjected to a large thrust or violent shaking.

[0071] Compared with the prior art, the present invention can rotate the rotatable sign in the prior art to a horizontal state or fold it toward the column 1 to achieve the purpose of reducing the windward area, thereby reducing the thrust of the wind on the sign and preventing the sign body 3 from being subjected to a large thrust or violent shaking.

[0072] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
