DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1-3 A sign-guiding device with a road sign switching structure comprises a support 1, an installation box 2, a motor 4 and two groups of sign components 3. The motor 4 and the two groups of sign components 3 are installed in the installation box 2, and the installation box 2 is supported by the support 1. When in use, the support 1 is placed in a suitable position, and pedestrians and vehicles are guided by the sign components 3. The sign style can be changed by driving the sign components 3 through the motor 4 to realize road sign switching.

[0030] The support 1 includes a base 11 and a mounting rod 12. A plurality of movable wheels 13 are arranged at the bottom of the base 11. The base 11 ensures the stability of the entire sign and guide device and reduces the risk of rollover. Road signs are generally unchanged. Usually, only roads in a semi-construction state will change road signs in a timely manner according to road surface adjustments. Therefore, the use scenario of the sign and guide device with a road sign switching structure is usually a temporary indication of a construction road surface. In order to improve the convenience of use, movable wheels 13 are installed at the bottom of the base 11 to facilitate the adjustment of the position of the sign and guide device. The movable wheels 13 are locking universal wheels, and the movable wheels 13 can be self-locked to maintain stability.

[0031] The installation box 2 is fixedly installed on the top of the installation rod 12, and two symmetrically arranged display openings 21 are opened on the installation box 2. The identification component 3 located in the installation box 2 can be exposed through the display openings 21, and a light box 22 corresponding to the display openings 21 is fixedly installed in the installation box 2. The light box 22 can emit bright light, thereby improving the recognition of the identification component 3.

[0032] The identification component 3 includes two transmission shafts 31, which are rotatably arranged in the installation box 2, and the two transmission shafts 31 are parallel to each other. A chain transmission mechanism is arranged between the two transmission shafts 31. Under the action of the chain transmission mechanism, when one of the transmission shafts 31 rotates, the other transmission shaft 31 is driven to rotate synchronously. The identification component 3 also includes an identification belt 32, and different types of guide logos 33 are distributed on the identification belt 32 at intervals. The two ends of the identification belt 32 are respectively wound on different transmission shafts 31, so that the identification belt 32 is in a taut state. The taut part of the identification belt 32 corresponds to the guide logo 33 and is displayed through the display port 21, which is used to guide pedestrians and vehicles. The motor 4 is fixedly installed in the installation box 2. The motor 4 is used to drive the transmission shaft 31 to rotate and reel in the identification tape 32, and switch the guide logo 33 displayed at the display port 21. When the motor 4 drives the transmission shaft 31 to rotate, one of the transmission shafts 31 starts to reel in, and the other transmission shaft 31 unwinds synchronously, so that the position of the guide logo 33 on the identification tape 32 changes, and different guide logos 33 are switched to be displayed at the display port 21, which meets a wider range of guidance needs, reduces the cost of replacing logos, and saves costs. In addition, by printing different types of guide logos 33 on the identification tape 32, more types of switchable logos are available, not just limited to direction logos, and the use effect is better.

[0033] The guide mark 33 on the identification tape 32 is made of a light-transmitting material, and the other parts of the identification tape 32 except the guide mark 33 are made of a non-light-transmitting material. A light box 22 is arranged in the installation box 2. The light emitted by the light box 22 passes through the identification tape 32 and passes through the guide mark 33 part, so that the brightness contrast between the guide mark 33 and the rest of the parts is increased, making it more eye-catching and clear.

[0034] Reference Figure 1-3 The outer contour of the guide sign 33 is adapted to the display opening 21. When one of the guide signs 33 is located at the center of the display opening 21, the guide sign 33 at the adjacent position is not within the display range of the display opening 21, thereby ensuring the accuracy of the content displayed in the display opening 21 and preventing multiple guide signs 33 from appearing in the display opening 21, thereby affecting the driver's judgment of the road traffic conditions.

[0035] Reference Figure 4-5 A worm gear 36 is fixedly provided on the transmission shaft 31 located below, and a worm 41 is fixedly provided on the output end of the motor 4. The worm 41 is meshed and connected with the two worm gears 36 at the same time. After the motor 4 is started, the worm 41 is driven to rotate, thereby driving the worm wheel 36 to rotate, driving the transmission shaft 31 to rotate, and realizing the winding and unwinding of the identification tape 32. Through the cooperation of the worm wheel 36 and the worm 41, the transmission shaft 31 can have a self-locking effect. After the motor 4 stops rotating, under the limiting action of the worm 41, the worm wheel 36 cannot rotate, thereby ensuring the position stability of the transmission shaft 31, and then ensuring the accurate position of the guide mark 33.

[0036] Reference Figure 4-5 The chain transmission mechanism includes a sprocket 34 fixedly set on the transmission shaft 31. The two sprockets 34 are connected by a chain 35. When the transmission shaft 31 rotates, the sprocket 34 is driven to rotate, and the other transmission shaft 31 is driven to rotate through the chain 35, so that the two transmission shafts 31 keep rotating synchronously, so that the two ends of the identification belt 32 are retracted and unwound synchronously, thereby keeping it in a taut state.

[0037] The two groups of identification components 3 are symmetrically distributed on both sides of the light box 22, and the guide signs 33 at corresponding positions on the two identification tapes 32 are mirror-symmetrical, ensuring that the contents displayed by the two groups of identification components 3 are consistent. By setting up two groups of identification tapes 32, pedestrians and vehicles can observe corresponding guidance information in different driving directions, thereby improving the guidance effect and safety. It should be noted that the guidance signs 33 with direction signs are in opposite directions when they are mirror-symmetrical. For example, when the identification and guidance device is placed along the east-west direction, pedestrians on the south side observe that the guidance sign 33 points to the right, while pedestrians on the north side observe that the guidance sign 33 points to the left. In fact, the guidance signs 33 on the two identification tapes 32 both point to the east.

[0038] Reference Figure 1 and 6 The identification guide device also includes a brush strip 5 fixedly arranged on the upper and lower sides of the display port 21. The brush strip 5 is in contact with the outer surface of the identification tape 32. During the winding and unwinding process of the identification tape 32, the part of the identification tape 32 exposed in the display port 21 will rub against the brush strip 5. The surface of the identification tape 32 is decontaminated by the brush strip 5 to ensure the cleanliness of the surface of the identification tape 32.

[0039] Working principle:

[0040] When in use, place the support 1 in a suitable position so that the plane where the installation box 2 is located is placed perpendicular to the road surface to ensure that the two identification tapes 32 are facing the oncoming traffic, and start the motor 4. After the motor 4 is started, the worm 41 is driven to rotate, thereby driving the worm wheel 36 to rotate and driving the transmission shaft 31 to rotate. When the motor 4 drives the transmission shaft 31 to rotate, one of the transmission shafts 31 begins to reel in and the other transmission shaft 31 unwinds synchronously, so that the position of the guide mark 33 on the identification tape 32 changes, and different guide marks 33 are switched to be displayed in the display port 21 to meet a wider range of guidance needs. The light emitted by the light box 22 passes through the identification tape 32 and partially passes through the guide mark 33, so that the brightness contrast between the guide mark 33 and the rest is increased, making it more eye-catching and clear. During the process of reeling and unreeling the identification tape 32, the part of the identification tape 32 exposed in the display port 21 will rub against the brush strip 5, and the surface of the identification tape 32 is decontaminated by the brush strip 5 to ensure the cleanliness of the surface of the identification tape 32.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
