Description

Technical Field

[0001] The utility model relates to the technical field of indication signs, in particular to an indication sign for a highway. Background Art

[0002] Signs have the function of marking and warning. Signs mainly express their functions through vision, such as text communication, and symbols have symbolic, directional, suggestive and other functions. Signs are a kind of information transmission media, which have the functions of advertising and warning. With the development of society, various signs have been put into the market.

[0003] After searching, a Chinese patent with announcement number CN219908657U discloses a signboard, including a signboard, both ends of the signboard are fixed with fixed rods, the lower ends of the fixed rods are fixed with fixed shafts, two rotating sleeves are sleeved on the fixed shafts, two support rods are respectively arranged on both sides of the fixed shaft, one end of the two support rods on the same side is respectively fixed to a rotating sleeve, and the two support rods on the same rotating sleeve are centrally symmetrically distributed with the fixed rod as the center. When the support rods are separated into a V shape, it is suitable for situations with high wind speeds, and it is convenient for users to press the support rods with heavy objects. At the same time, the gaps between the support rods can clamp the heavy objects, preventing the heavy objects from falling due to uneven force, or the support rods from losing fixation due to external force offset. Prevent the signboard from tipping over. The signboard of the present application solves the problem of the difficulty in fixing the signboard.

[0004] When building roads in villages, signboards are needed to indicate or warn passing vehicles or pedestrians to prevent them from entering the road construction area. Although the above solution can solve the problem of the difficulty in fixing the signboards, it is difficult to adjust the height of the signboards according to different environments, and the indication effect is poor, which can easily cause unnecessary accidents at the road construction site. To this end, we provide a road sign to solve the above problems. Utility Model Content

[0011] Furthermore, one end of the upper surface of the first base is fixedly connected to one end of the fixed plate, and a slide groove on one side of the fixed plate is slidably connected to one side of the slide rail, which plays a supporting role and can support the lifting mechanism to prevent shaking during lifting.

[0012] Furthermore, one end of the lifting plate is connected to an indication mechanism, which includes a flashing warning light, one end of which is fixedly connected to the outside of the indication box, and an inner slide rail of the indication box is fixedly connected to one end of a hydraulic telescopic rod, so that on rainy days, water mist will not appear on the sign, making it impossible to see the indication information clearly.

[0013] Furthermore, the other end of the hydraulic telescopic rod is fixedly connected to one end of the sliding plate, one side of the sliding plate is fixedly connected to one side of the sponge, and the other side of the sponge is slidably connected to the surface of the signboard. The surface of the signboard can be quickly wiped through the sensor to prevent the information on the signboard from being unable to be transmitted in time.

[0014] Compared with the prior art, the highway sign has the following beneficial effects:

[0015] 1. The utility model is provided with a lifting mechanism, and the second motor drives the third rotating shaft to rotate, so that the second bevel gear and the first bevel gear work synchronously to drive the first threaded rod to lift the lifting plate up and down, so as to provide an indication information to passing vehicles on different roads, and prevent passing vehicles from missing the indication information due to untimely observation.

[0016] 2. The utility model is provided with a supporting and fixing mechanism, and moves the mobile bracket to the road surface to be indicated. The first motor drives the second rotating shaft, and the first belt drives the first rotating shaft to rotate so that the first rotating screw can be fixed on the road surface, thereby preventing the danger of the signboard collapsing when passing vehicles are driving at high speed.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] See also Figure 1 , Figure 2 and Figure 3 A road sign includes a lifting mechanism 2, the lifting mechanism 2 includes a second support plate 201, one end of the second support plate 201 is connected to the supporting and fixing mechanism 1, the supporting and fixing mechanism 1 includes a movable bracket 101, one end of the movable bracket 101 is fixedly connected to one end of the lower surface of the first base 102, one end of the upper surface of the first base 102 is fixedly connected to one end of the fixed plate 208, a side slide groove of the fixed plate 208 is slidably connected to one side of the slide rail 203, and a lifting plate 206 is supported to prevent the lifting plate 206 from shaking when sliding up and down, resulting in the sign 305 being unable to be lifted normally, and the middle part of the upper surface of the first base 102 is fixedly connected to one end of the first support plate 103, playing a supporting role. When indicating on the road, road information will be played to passing vehicles to prevent passing drivers from failing to find the message ahead in time.

[0028] One side of the first support plate 103 is fixedly connected to the first motor 104, and the output shaft of the first motor 104 is fixedly connected to one end of the second shaft 108. The second shaft 108 is driven by the first motor 104 to rotate so that the sign 305 can be quickly fixed on the road. The middle part of the outer cylindrical surface of the second shaft 108 is transmission-connected to one end of the first belt 105, and the other end of the first belt 105 is transmission-connected to the middle part of the outer cylindrical surface of the first shaft 106. One end of the first shaft 106 is fixedly connected to one end of the first rotating screw nail 107. Generally, the road construction site is a soil ground, and the existing sign is not convenient to be fixed on the soil road. The first belt 105 drives the first rotating screw nail 107 to be quickly fixed on the soil ground under the drive of the first motor 104, which effectively prevents the sign 305 from collapsing. The upper surface of the second support plate 201 is fixedly connected to the second motor 202, and the output shaft of the second motor 202 is fixedly connected to one end of the third shaft 213.

[0029] Referring to FIG. 4 , the third rotating shaft 213 is set to be circular, and a right angle bracket 212 is rotatably set in the middle of one end of the third rotating shaft 213. The circular width value of the third rotating shaft 213 is smaller than the width value of the right angle bracket 212, which plays a role of fixing the third rotating shaft 213 when the second motor 202 drives the third rotating shaft 213 to rotate, so as to prevent the rotating shaft from shaking and affecting the indicator sign 305. One end of the third rotating shaft 213 is fixedly connected to one side of the second bevel gear 211, and the teeth on one side of the outer circumference of the second bevel gear 211 are meshed with the teeth on one side of the outer circumference of the first bevel gear 210, and one side of the first bevel gear 210 is connected to the first threaded rod 204. One end of the first threaded rod 204 is fixedly connected, the other end of the first slider 205 is rotatably connected, the other end of the first slider 205 is fixedly connected to the lower end of one side of the lifting plate 206, one end of the lifting plate 206 is connected to the indicating mechanism 3, the indicating mechanism 3 includes a flashing warning light 304, one end of the flashing warning light 304 is fixedly connected to the outer side of the indicating box 303, the inner side slide rail 203 of the indicating box 303 is fixedly connected to one end of the hydraulic telescopic rod 301, and the lifting mechanism 2 can be automatically controlled to lift and lower automatically through the drive of the second motor 202, so as to effectively prevent the sign 305 from falling in windy weather.

[0030] See also Figure 5The other end of the hydraulic telescopic rod 301 is fixedly connected to one end of the sliding plate 302, one side of the sliding plate 302 is fixedly connected to one side of the sponge 306, and the other side of the sponge 306 is slidably connected to the surface of the sign 305. On rainy days, the rain, fog and dust on the surface of the sign 305 can be automatically cleaned by the sensor to prevent the sign 305 from having unclear information due to long-term storage. The lower end of the other side of the lifting plate 206 is fixedly connected to one end of the second slider 207, and the other end of the second slider 207 is slidably connected to the outer circular surface of one end of the sliding rod 209, which can be automatically raised and lowered according to different roads, so as to facilitate timely message indication to passing vehicles.

[0031] Working principle: The mobile bracket 101 is pushed to the designated location by the worker. When the first motor 104 drives the second rotating shaft 108 to rotate, the first belt 105 drives the first rotating shaft 106 to rotate, so that the first rotating screw 107 can be quickly fixed at the designated location, effectively preventing the sign 305 from suddenly falling due to strong winds and causing damage to passing vehicles, affecting driving safety. The second motor 202 drives the third rotating shaft 213 to rotate, so that the second bevel gear 211 and the first bevel gear 210 rotate synchronously, driving the first threaded rod 204 to The lifting plate 206 can be adjusted up and down to automatically control different lifting heights and different usage methods. The flashing warning light 304 can flash at night and when visibility is poor to prevent passing vehicles from failing to find the sign 305 in time. The hydraulic telescopic rod 301 pushes the sliding plate 302 to slide back and forth, so that dust can be quickly cleaned on rainy days and for a long time, effectively increasing the service life of the sign 305. The sponge 306 wipes the sign 305 back and forth as the hydraulic telescopic rod 301 and the sliding plate 302 slide back and forth.
