DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Embodiment 1:

[0025] See also Figure 1 , Figure 2The present invention shows a dual-screen information advertising machine, comprising an installation frame 1, a chassis 2 is arranged on the top of the installation frame 1, the interior of the chassis 2 is divided into a screen cavity 4 and installation cavities 5 located on the left and right sides of the screen cavity 4 by two vertical panels 3, tempered glass 6 connected to the interior of the screen cavity 4 is embedded in the middle of the front and rear side walls of the chassis 2, and two display screens 7 facing the two tempered glasses 6 are symmetrically arranged in a back-to-back manner in the screen cavity 4; the outer surfaces of the two tempered glasses 6 are slidably provided with a transversely arranged installation plate 8, and the two installation cavities 5 are provided with a drive installation device. The lifting mechanism for lifting the mounting plate 8 is also provided with a driving mechanism for driving the mounting plate 8 to move horizontally; a rubber scraper 9, a water spray pipe 10 and a cleaning brush 11 are horizontally provided from top to bottom on the side of the mounting plate 8 close to the chassis 2, and a plurality of water spray nozzles 12 connected to the water spray pipe 10 are provided at equal intervals along its length direction, and the water spray pipe 10 is connected with a water supply component. In actual use, by setting the lifting mechanism, the driving mechanism, the rubber scraper 9, the cleaning brush 11 and the water spray nozzle 12, the lifting mechanism can drive the mounting plate 8 to move up and down , thereby driving the rubber scraper 9, the cleaning brush 11 and the water nozzle 12 to move up and down. Before the lifting mechanism drives the rubber scraper 9, the cleaning brush 11 and the water nozzle 12 to move upward through the mounting plate 8, the driving mechanism has driven the mounting plate 8 to move horizontally away from the outer surface of the tempered glass 6, thereby preventing the rubber scraper 9 from contacting the outer surface of the tempered glass 6, preventing the rubber scraper 9 from directly contacting the dry dust during the process of the lifting mechanism driving the rubber scraper 9 to rise through the mounting plate 8, thereby causing the dust to rub against the tempered glass 6, thereby damaging the tempered glass. 6, which affects the display effect of the display screen 7 when viewing the tempered glass 6 later, and at the same time prevents the dry dust layer from damaging the surface of the rubber scraper 9 and affecting the normal operation of the rubber scraper 9. The lifting mechanism drives the rubber scraper 9, the cleaning brush 11 and the water spray nozzle 12 to move upward through the mounting plate 8. The rubber scraper 9 does not contact the outer surface of the tempered glass 6. The water supply component delivers cleaning liquid to the water spray pipe 10, so that the water spray nozzle 12 sprays cleaning liquid to wash the dust adhered to the outer surface of the tempered glass 6 and moisturize it.When the lifting mechanism drives the rubber scraper 9, the cleaning brush 11 and the water nozzle 12 to move to the highest point, the driving mechanism drives the mounting plate 8 to move horizontally and then move close to the outer surface of the tempered glass 6, so that the rubber scraper 9 and the cleaning brush 11 are in conflict with the outer surface of the tempered glass 6. At this time, the lifting mechanism drives the rubber scraper 9, the cleaning brush 11 and the water nozzle 12 to move downward, the cleaning brush 11 first brushes the outer surface of the tempered glass 6, and the cleaning liquid sprayed by the water nozzle 12 rinses and cleans the stains brushed by the cleaning brush 11, and the rubber scraper 9 is attached to the surface of the tempered glass 6 and the water nozzle 12. Scrape the water marks left after rinsing and cleaning, thereby avoiding the situation where water marks are left on the surface of the tempered glass 6 after cleaning, so as to clean the outer surface of the tempered glass 6. Through this structure, the outer surfaces of the tempered glass 6 on the front and rear sides of the chassis 2 can be cleaned at the same time, which improves practicality. By setting the tempered glass 6, the outside world can watch the display content of the two display screens 7 arranged in the screen cavity 4 through the tempered glass 6, avoiding the surface of the display screen 7 being directly exposed to the outside world, and avoiding the damage to the display screen 7 caused by the external environment, so as to better protect the display screen 7 and improve the service life of the product. ; Embodiment 2:

[0026] See also Figure 1 , Figure 2 As shown, both ends of the front and rear side walls of the chassis 2 are vertically provided with strip grooves 13 connected to the installation cavity 5; the lifting mechanism includes a driving block 14, and a reciprocating screw 15 is vertically rotated in the installation cavity 5. A synchronous motor 16 is provided on the bottom side of the chassis 2, and the output shaft of the synchronous motor 16 passes through the bottom side of the chassis 2 and is transmission-connected to the reciprocating screw 15, and the driving block 14 is threadedly connected to the reciprocating screw 15; both the front and rear side walls of the driving block 14 are horizontally provided with a telescopic rod 17, and the end of the telescopic rod 17 away from the driving block 14 passes through the strip groove 13 to pass through the installation cavity 5 and is connected to the mounting plate 8. By providing the strip groove 13, it can be ensured that the driving mechanism and the telescopic rod 17 can be smoothly raised or lowered under the drive of the lifting mechanism. In actual use, the synchronous motor 16 drives the reciprocating screw 15 to rotate, and the driving block 14 is threadedly engaged with the reciprocating screw 15, thereby driving the driving block 14 to move up and down. The synchronous motor 16 is provided to ensure the synchronization of the rotation of the reciprocating screws 15 in the two installation cavities 5.

[0027] See also Figure 4 , Figure 5As shown, the telescopic rod 17 includes a sleeve 18 and a support rod 19, the sleeve 18 is provided with a center groove 20, one end of the support rod 19 is connected to the mounting plate 8, and the other end is inserted into the center groove 20, and the end of the sleeve 18 away from the support rod 19 is connected to the driving block 14; a tension spring 21 is provided inside the center groove 20, one end of the tension spring 21 is connected to the support rod 19, and the other end is fixedly connected to the bottom of the center groove 20, and the driving mechanism drives the mounting plate 8 to move horizontally so that the rubber scraper 9 and the cleaning brush 11 are connected to the outer surface of the tempered glass 6 When the surfaces are in contact, the support rod 19 is completely placed in the center groove 20. By setting the support rod 19 and the sleeve 18, the support rod 19 is plugged and connected to the sleeve 18 through the center groove 20. When the driving mechanism drives the mounting plate 8 to move horizontally, the telescopic rod 17 is telescoped to support the mounting plate 8, thereby ensuring the stability of the mounting plate 8 during horizontal movement. By setting the tension spring 21, the support rod 19 is prevented from completely sliding out of the center groove 20 when the mounting plate 8 moves horizontally away from the outer surface of the tempered glass 6, thereby ensuring the stability of the connection.

[0028] See also Figures 2 to 5As shown, the driving mechanism includes a slider 22, the height of the slider 22 is higher than the height of the driving block 14, and a sliding groove 23 running through the upper and lower sides of the driving block 14 is vertically opened at one end of the driving block 14 away from the screen cavity 4, and the slider 22 is slidably connected to the driving block 14 through the sliding groove 23, and the bottom of the slider 22 away from the driving block 14 is rotatably connected to two movable rods 25 through a fixing bolt 24, and the ends of the two movable rods 25 away from the fixing bolt 24 respectively pass through the strip groove 13, and are rotatably connected to the end of the mounting plate 8 through a connecting bolt 26; the length of the movable rod 25 is longer than the length of the sleeve 18, and a limiting component for stopping the slider 22 from sliding along the sliding groove 23 is provided on the slider 22 of the driving block 14. In actual use, by setting the slider 22 and the movable rod 25 The movable rod 25 can automatically drive the mounting plate 8 away from or close to the front and rear sides of the chassis 2. The driving block 14 drives the slider 22 to move downward. When the bottom of the slider 22 contacts the bottom wall of the mounting cavity 5, the slider 22 stops moving. At this time, the driving block 14 continues to move downward, so that the movable rod 25 rotates with the fixing bolt 24 as the axis. Under the action of the connecting bolt 26, a supporting force is generated on the mounting plate 8, driving the two mounting plates 8 to move horizontally away from the outer surface of the tempered glass 6 respectively. At this time, the telescopic rod 17 is extended to continue to support the mounting plate 8, and at the same time, it plays a limiting role for the mounting plate 8 during horizontal movement. When the driving block 14 moves downward until its bottom is flush with the bottom of the slider 22, the limiting component limits the slider 22 to prevent the slider from 22 and the driving block 14 slide relative to each other so that the mounting plate 8 moves close to the chassis 2, thereby ensuring that the rubber scraper 9 and the cleaning brush 11 do not directly contact the transparent glass during the rise, preventing the rubber scraper 9 and the cleaning brush 11 from directly contacting the dry dust, thereby causing the dust to rub against the tempered glass 6, scratching the outer surface of the tempered glass 6, affecting the subsequent display effect of the display screen 7 viewed through the tempered glass 6, and preventing the dry dust layer from damaging the surface of the rubber scraper 9 and affecting the normal operation of the rubber scraper 9. When the driving block 14 drives the slider 22 up to the top of the slider 22 and contacts the top wall of the mounting cavity 5, the slider 22 stops moving. At this time, the driving block 14 continues to move upward, so that the movable rod 25 is fixed The bolt 24 rotates about the axis, generating a pulling force on the mounting plate 8, driving the two mounting plates 8 to move horizontally close to the tempered glass 6 respectively. At this time, the telescopic rod 17 is shortened to support the mounting plate 8, and at the same time, it plays a limiting role for the mounting plate 8 during horizontal movement. When the driving block 14 moves upward to the point where its top is flush with the top of the slider 22, the telescopic rod 17 retracts to the shortest length, so that the rubber scraper 9 and the cleaning brush are close to the outer surface of the tempered glass 6. At the same time, the limiting assembly limits the slider 22, so that there is no relative movement between the slider 22 and the driving block 14, ensuring that the cleaning brush 11 can fully scrub the surface of the tempered glass 6 when moving downward, and at the same time ensuring that the rubber scraper 9 can scrape off water marks when moving downward.

[0029] See also Figure 3 and Figure 7 As shown, a groove 27 is provided at the bottom of the sliding groove 23; the limiting assembly includes an upper protrusion 28 and a lower protrusion 29; an upper mounting groove 30 and a lower mounting groove 31 are provided on the side of the slider 22 close to the screen cavity 4; support springs 32 are provided in the upper mounting groove 30 and the lower mounting groove 31; one end of the two support springs 32 is respectively connected to the bottom of the upper mounting groove 30 and the lower mounting groove 31, and the other end is respectively connected to one end of the upper protrusion 28 and the lower protrusion 29; the other ends of the upper protrusion 28 and the lower protrusion 29 respectively pass through the notches of the upper mounting groove 30 and the lower mounting groove 31; when the bottom of the slider 22 is flush with the bottom of the driving block 14, the end of the lower protrusion 29 away from the support spring 32 is placed in the groove 27, and the top of the slider 22 is flush with the top of the driving block 14 Normally, the end of the upper protrusion 28 away from the support spring 32 is placed in the groove 27. By setting the groove 27, the upper protrusion 28 and the lower protrusion 29, when in use, when the driving block 14 drives the slider 22 to move upward, the end of the lower protrusion 29 away from the support spring 32 is placed in the groove 27 under the action of the support spring 32, and the slider 22 is limited. When the driving block 14 drives the slider 22 to move upward so that the top of the slider 22 contacts the top of the installation cavity 5, when the driving block 14 continues to move upward relative to the slider 22, the groove wall of the sliding groove 23 forms an extrusion force on the lower protrusion 29, so that the end of the lower protrusion 29 slides out of the groove 27 and retracts into the lower installation groove 31, and the slider 22 is no longer limited, so that the slider 22 and the sliding groove 23 are produced. When the top of the driving block 14 rises to be flush with the top of the slider 22, the upper protrusion 28 is caused to pass through the upper mounting groove 30 and is placed in the groove 27 under the elastic force of the support spring 32, thereby limiting the position of the slider 22. Conversely, when the driving block 14 drives the slider 22 to move downward so that the bottom of the slider 22 is flush with the bottom wall of the mounting cavity 5, when the driving block 14 continues to move downward relative to the slider 22, the groove of the sliding groove 23 is pressed against the slider 22, and the upper protrusion 28 is pressed against the upper mounting groove 30 and is pressed against the support spring 32. The wall forms an extrusion pressure on the upper protrusion 28, so that the end of the upper protrusion 28 slides out of the groove 27 and retracts into the upper mounting groove 30, and the slider 22 is no longer limited, so that the slider 22 and the sliding groove 23 slide relative to each other. At this time, the driving block 14 continues to move downward relative to the slider 22. When the groove wall of the sliding groove 23 contacts the lower protrusion 29, the groove wall produces an extrusion pressure on the lower protrusion 29, so that the lower protrusion 29 retracts into the upper mounting groove 30 and produces a pressure on the support spring 32. When the top of the driving block 14 drops to be flush with the top of the slider 22, the lower protrusion 29, under the elastic force of the support spring 32, makes the end away from the support spring 32 pass through the upper mounting groove 30 and be placed in the groove 27, thereby realizing the function of limiting the slider 22.

[0030] See also Figure 1 , Figure 2 As shown, the water supply assembly includes a water supply tank 33 and a telescopic pipe 34. The water supply tank 33 is arranged at the bottom of the installation frame 1. A water injection port is provided on the side wall of the water supply tank 33, through which clean water can be conveniently added to the inside of the water supply tank 33 for flushing. A water pump 35 is provided inside the water supply tank 33. One end of the elastic tube passes through the side wall of the water storage tank and is connected to the water outlet end of the water pump 35, and the other end is connected to the water spray pipe 10 through a water distribution pipe 36. In actual use, the water pump 35 can pump the clean water inside the water supply tank 33 to the elastic tube, and then send it to the water spray pipe 10 through the water distribution pipe 36, and finally spray it out through the water spray nozzle 12 for flushing and cleaning the screen.

A cross-flow fan 40 is provided on the bottom side of the chassis 2 opposite to the air vents 38, and a top cover 42 is provided on the top of the chassis 2 through a support frame 41. By setting the air inlet 37 for air intake, the cross-flow fan 40 can accelerate the air flow inside the screen cavity 4, and then the hot air in the screen cavity 4 flows to the top and is discharged through the air outlet 39, so as to replace all the hot air in the screen cavity 4 and achieve uniform heat dissipation. At the same time, the air outlet 39 is provided at the top of the screen cavity 4. Since the air rises when heated, it is easier to replace and discharge the hot air inside the screen cavity 4 to achieve heat dissipation and ensure the normal operation of the display screen 7 inside the screen cavity 4. By setting the top cover 42, rainwater is prevented from entering the interior of the screen cavity 4 through the air outlet 39 on the top of the chassis 2 and affecting the display screen 7.
