Description

Technical Field

[0001] This invention relates to the field of signage technology, specifically to a folding and lifting signage with an automatic cleaning function. Background Technology

[0002] The materials used for signs are generally aluminum plates, aluminum composite panels, PVC panels, galvanized plates, and fiberglass panels. They are classified by purpose as: safety signs, power signs, fire safety signs, cartoon signs, and evacuation signs. Safety signs are directional signs installed for safety reasons to reduce safety hazards and can be seen at factory gates, inside factories, and on roads. Traffic safety signs required by the transportation department are divided into prohibition signs and warning signs. Various traffic safety signs are generally erected on both sides of the road, with various slogans on the signs to provide guidance to drivers.

[0003] When existing signs are in use, vehicles passing by on the road raise a lot of dust, which adheres to the sign surface. After a long period of use, the driver in the driver's seat can no longer see the warning messages on the sign, making it difficult for the driver to make driving judgments, thus posing a safety hazard. At the same time, the existing signs are all fixed in height, which increases the difficulty and danger for technical maintenance workers when repairing the signs or changing the information on the panel. To address the above problems, the existing equipment needs to be improved. Summary of the Invention

A vertical and horizontal moving device is set inside the front of the fixed frame near the support frame mechanism, and a cleaning mechanism is set on the side of the vertical and horizontal moving device near the sign body. The cleaning mechanism is located in front of the sign body. A through hole is opened on the side of the fixed frame near the support frame mechanism, and the position of the through hole is at the same level as the sign body.

[0007] Preferably, the support frame mechanism includes a base, an electric telescopic bracket, a lifting base plate, a lifting support column, an extension rod, a connecting rod, and a fixed connecting piece. The upper middle of the base is connected to the lower middle of the lifting base plate via the electric telescopic bracket. An extension rod is installed in the upper middle of the lifting base plate. Connecting rods are symmetrically arranged at the upper and lower ends of the extension rod. The other end of the connecting rod is connected to the back of the fixed frame via a fixed connecting piece and a fixing screw.

[0008] Preferably, lifting support columns are symmetrically arranged on the front and rear sides between the base and the lifting base plate, and the lifting support column includes a sleeve and a lifting rod. Guide rods are arranged on both sides inside the sleeve, and a moving plate is slidably connected to the two guide rods. At the same time, the lifting rod arranged at the upper end of the moving plate passes through the sleeve and connects to the lower end of the lifting base plate. A limit rod is arranged in the middle of the lower end inside the sleeve, and the upper end of the limit rod extends through the moving plate into the lifting rod. Meanwhile, a buffer spring is sleeved on the outside of the limit rod located between the moving plate and the lower end inside the sleeve.

[0009] Preferably, the sign body includes a base plate, the upper and lower ends of which are engaged and fixedly connected to the transverse engaging seats, and vertical support plates are symmetrically installed on both sides between the two transverse engaging seats.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-8 This invention provides a technical solution: a folding and lifting sign with an automatic cleaning function, based on... Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, an electronic display screen 101 is installed on one side of the front of the fixed frame 1 for video playback. This allows the sign body 3 to serve as a warning during cleaning by playing a video instead of the sign body 3, thus improving its practicality. The two ends of the back of the fixed frame 1 are connected to the ground through the support frame mechanism 2. At the same time, a control box 102 is installed in the middle of the back of the fixed frame 1 for controlling the equipment in the device, thereby achieving automatic operation and improving intelligence.

[0027] Specifically, the support frame mechanism 2 includes a base 201, an electric telescopic bracket 202, a lifting base plate 203, a lifting support column 204, an extension rod 205, a connecting rod 206, and a fixed connecting piece 207. The upper middle of the base 201 is connected to the lower middle of the lifting base plate 203 via the electric telescopic bracket 202. An extension rod 205 is installed at the upper middle of the lifting base plate 203. Connecting rods 206 are symmetrically arranged at the upper and lower ends of the extension rod 205. The other end of the connecting rod 206 is connected to the back of the fixed frame 1 via the fixed connecting piece 207 and a fixing screw. The electric telescopic bracket 202 facilitates the adjustment of the height of the extension rod 205, so that the sign body 3 is at a height that the driver can see.

[0028] To further explain, lifting support columns 204 are symmetrically arranged on the front and rear sides between the base 201 and the lifting base plate 203. The lifting support column 204 includes a sleeve 2401 and a lifting rod 2044. Guide rods 2042 are arranged on both sides inside the sleeve 2401, and a moving plate 2043 is slidably connected to the two guide rods 2042. At the same time, the lifting rod 2044 arranged on the upper end of the moving plate 2043 passes through the sleeve 2401 and is connected to the lower end of the lifting base plate 203. A limit rod 204 is arranged in the middle of the lower end inside the sleeve 2401. 5. The upper end of the limiting rod 2045 extends through the moving plate 2043 into the interior of the lifting rod 2044. At the same time, a buffer spring 2406 is sleeved on the outside of the limiting rod 2045 located between the lower end of the moving plate 2043 and the sleeve 2401. When the height is adjusted by the electric telescopic bracket 202, the lifting rod 2044 drives the moving plate 2043 to slide on the guide rod 2042, so that the buffer spring 2406 is stretched to support the moving plate 2043 and improve the overall stability of the support frame mechanism 2 during use.

[0029] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sign body 3 is installed inside the fixed frame 1, and the outer sides of the sign body 3 away from the fixed frame 1 are connected to the collection box 5 and the connecting seat 6 installed at the upper and lower ends of the fixed frame 1 respectively through electric hydraulic cylinders 4.

[0030] Specifically, the sign body 3 includes a base plate 301. The upper and lower ends of the base plate 301 are engaged and fixedly connected to the transverse locking seats 302. Vertical support plates 303 are symmetrically installed on both sides between the two transverse locking seats 302. At the same time, one end of the outer side of the two transverse locking seats 302 is connected to the moving crossbar 305 through the fixing block 304. One end of the moving crossbar 305 passes through the fixing frame 1 and is connected to the threaded seat. The other end of the moving crossbar 305 is connected to the output end of the electric hydraulic cylinder 4 through the baffle 306. When the electric hydraulic cylinder 4 drives the baffle 306 to move, the moving crossbar 305 drives the transverse locking seats 302 to move horizontally, thereby moving the position of the base plate 301 horizontally, which facilitates the cleaning of the sign body 3 with dust adhering to it.

[0031] To further explain, the collection box 5 has an L-shaped structure and a rain storage chamber inside. A filter screen 501 is installed at the top of the rain storage chamber to prevent dust and leaves from entering. A connecting plate 502 is installed on one side of the collection box 5, and the connecting plate 502 is connected to one side of the mounting base 701 at the bottom of the solar panel 7 by fixing screws. At the same time, the other side of the lower end of the mounting base 701 is connected to the lower end of one side of the collection box 5 by a mounting bracket 702, which facilitates the utilization of solar energy and improves the practicality of the device.

[0032] according to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a vertical and horizontal moving device 103 is provided inside the fixed frame 1 on the side near the support rod mechanism 2. The vertical and horizontal moving device 103 facilitates the lifting and lowering of the cleaning mechanism 8, improving the cleaning effect. The cleaning mechanism 8 is provided on the side of the vertical and horizontal moving device 103 near the sign body 3. The cleaning mechanism 8 is located in front of the sign body 3. A through hole 104 is provided on the side of the fixed frame 1 near the support rod mechanism 2. The position of the through hole 104 is at the same level as the sign body 3, so that when cleaning, one end of the sign body 3 can pass through the through hole 104 to clean the other end of the sign body 3.

[0033] Specifically, the cleaning mechanism 8 includes a cleaning seat 802. The upper and lower ends of one side of the back of the cleaning seat 802 are provided with grooves. A spray device 804 is installed inside the upper groove. A fixed baffle 805 is engaged with one side of the front of the spray device 804. The upper end of the spray device 804 passes through the cleaning seat 802 and the lower bottom of the collection box 5 via a connecting pipe 801. A solenoid valve 803 is installed on the connecting pipe 801. The spray device 804 includes a delivery pipe and multiple spray heads. By opening the solenoid valve 803, rainwater enters the delivery pipe through the connecting pipe 801 and is finally sprayed out through the spray heads to rinse the sign body 3. A cleaning cotton block 806 is provided inside the lower groove for easy wiping and cleaning of dust.

[0034] To further explain, one side of the cleaning cotton pad 806 is engaged with the insert rods 808 provided on both sides inside the placement frame 807, and the other two ends of the placement frame 807 are connected to the lower groove through electric push rods 809. The electric push rods 809 push the placement frame 807 to move towards the sign body 3, so that the cleaning cotton pad 806 fits into the sign body 3, thereby cleaning the dust on the sign body 3.
