Description

Technical Field

[0001] This invention relates to the field of signage wall technology, and more specifically, to a signage wall for promoting resources and the environment and its usage method. Background Technology

[0002] The concept of resources and environment arises from a deeper understanding of natural resources and environmental resources. Almost all natural resources constitute environmental factors for human survival. Natural resources refer to various independent static substances and energies that are available for human use within a certain time and space. With social development, resources and environment are receiving increasing attention. In order to make more people aware of resources and environment, publicity is needed.

[0003] The prior art publication CN216305239U provides a signage wall for promoting resource and environmental protection. This device is equipped with a servo motor. When the servo motor is turned on, it drives a sliding block to move via a threaded rod. This causes the sliding block to disengage a locking block from its locking groove, facilitating the removal of the promotional signage. When replacing a new signage, an insertion rod is inserted into the insertion hole, and the servo motor is controlled to rotate in the opposite direction. This causes the threaded rod to move the sliding block in the opposite direction, and the sliding block engages the locking block in its locking groove, making the replacement of the promotional signage very convenient.

[0004] While the existing technical solutions have many beneficial effects, they still have the following drawbacks: When in use, the simple and fixed structure of the advertising signboard limits its display to a single environmental resource, making it difficult to change the displayed images; furthermore, the device makes it inconvenient to clean the advertising board, leading to the accumulation of dust and other contaminants, which affects its advertising effect. Therefore, we propose a signboard wall for advertising environmental resources. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this invention is to provide a signage wall for promoting resources and the environment, thereby solving the technical problems mentioned in the background section.

[0007] 2. Technical Solution

The outer end of the threaded rod is coaxially and fixedly connected to the output end of the motor. The movable frame is threadedly connected to the outer wall of the threaded rod.

[0020] As an optional solution to the technical solution of this application, a transmission bar is fixedly connected to one side of the mobile frame, and multiple transmission ratchet teeth are hinged to the lower inner wall of the transmission bar. The transmission ratchet teeth are fixedly connected to the transmission bar by springs.

[0021] One end of the worm gear is fixedly connected to a ratchet, which meshes with a transmission ratchet tooth for transmission.

[0022] As an optional solution to the technical solution of this application, the banner cleaning mechanism includes an L-shaped guide rod and a wiping plate, wherein the lower outer wall of the L-shaped guide rod is slidably fitted through the outer wall of the movable frame;

[0023] The bottom surface of the upper end of the signage wall is provided with a guide groove, which is set in a bent structure, with the bend of the guide groove corresponding to the guide groove.

[0024] The inner wall of the guide groove is slidably fitted with the outer wall of the L-shaped guide rod. The curved structure of the guide groove allows the banner cleaning mechanism to come into contact with the advertising banner.

[0025] A wiping plate is slidably fitted on the inner side of the other end of the L-shaped guide rod, and the outer wall of the wiping plate near the banner is in frictional contact with the outer wall of the banner.

[0027] A convex and concave plate is fixedly connected to the bottom surface of the upper end of the signage wall, and the outer wall of the convex and concave plate is slidably in contact with the upper end of the extrusion plug.

[0028] The L-shaped guide rod is slidably mounted at the lower end of the mobile frame.

[0029] A drive rod is provided through the inner wall of the other end of the L-shaped tube in a sealed sliding fit. One end of the drive rod located inside the L-shaped tube is connected and fixedly provided with a tension spring, and the other end of the tension spring is connected and fixedly provided with the inner wall of the L-shaped tube.

[0030] By adopting the above technical solution, the tension spring achieves the automatic reset function of the drive rod.

[0031] As an optional solution to the technical solution of this application, a sliding rod is fixedly connected to the outer wall of the other end of the drive rod;

[0032] The inner walls on both sides of the upper end of the wiping plate are provided with inclined guide grooves, and the inner walls of the inclined guide grooves are slidably fitted with the outer walls of the sliding rod.

[0033] This invention also provides a method for using a signboard wall to promote resources and the environment, comprising the following steps:

[0034] Step 1: Close and roll the banner printed with images of resources and the environment around the friction roller and support plate on the shelf;

[0035] Step 2: Insert the limiting baffle into the friction roller and fix it with screws;

[0036] Step 3: Then push the placement rack to fix the support plate in the placement slot; at this time, the promotional content of the banner can be seen through the front opening of the placement slot;

[0037] Step 4: When it is necessary to clean the banner, start the motor to drive the threaded rod to rotate, which in turn drives the moving frame to move. At this time, the moving frame will drive the banner cleaning mechanism to move. When the upper end of the L-shaped guide rod moves to the protrusion of the guide groove, the L-shaped guide rod will drive the wiping plate to move closer to the banner, so that it can contact the banner for cleaning.

[0038] Step 5: When the moving frame moves, the squeezing plug will contact the convex and concave plates, causing the squeezing plug to move down and squeeze the gas in the L-shaped tube towards the drive rod, thereby pushing the drive rod to move. Then, under the action of the sliding rod, it can slide in the inclined guide groove, thereby driving the wiping plate to move up and down reciprocally for wiping.

[0039] Step 6: When the transmission ratchet on the transmission bar contacts the ratchet, it will drive the ratchet to rotate, which in turn drives the connected worm gear to rotate. This causes the worm gear to drive the limit baffle connected to the worm gear to rotate, which in turn drives the friction roller to rotate, thereby driving the banner to rotate and changing the display of different resource environment pictures.

[0040] 3. Beneficial effects

[0041] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0042] 1. This application effectively solves the technical problems in the prior art by adopting a banner cleaning mechanism. When the device is in use, the wiping plate can come into contact with the banner under the drive of the transmission mechanism, thereby cleaning the exposed images of the banner and maintaining the promotional display effect of the device.

[0043] 2. By setting an adjustment mechanism on the transmission mechanism, this application allows the wiping plate to move up and down rapidly during movement, in conjunction with the concave and convex plates, thereby improving the cleaning effect on the advertising banner.

[0044] 3. This application utilizes a transmission ratchet. When the transmission mechanism drives the banner cleaning mechanism for moving and cleaning, the transmission ratchet can drive the worm gear to rotate, thereby driving the friction roller to rotate, which in turn drives the advertising banner to rotate. This achieves the function of automatically changing the advertising images of different resource environments, thus improving the practicality of the device. Attached Figure Description

[0071] Reference Figure 3 , Figure 6 and Figure 7 The adjusting mechanism 7 includes an L-shaped tube 701, a compression plug rod 702, a drive rod 703, and a sliding rod 705;

[0072] L-shaped tube 701 and L-shaped guide rod 601 are connected and fixedly installed. A compression plug 702 is provided through and slidably fitted on the inner wall of one end of L-shaped tube 701. A convex and concave plate 104 is fixedly installed on the bottom surface of the upper end of the marking wall 1.

The inclined guide grooves 603 enable the wiping plate 602 to move up and down reciprocally when the sliding rod 705 moves.

[0075] Working principle: When it is necessary to promote resources and the environment, the banner 4 printed with pictures of resources and the environment can be closed and rolled around the friction roller 301 and support plate 304 on the placement frame 3, and the limiting baffle 302 is inserted into the friction roller 301 and fixed with screws; then push the placement frame 3 to fix the support plate 304 in the placement groove 2.

[0076] At this time, the advertising banner 4, which is the content to be advertised, can be seen through the front opening of the placement slot 2. When the advertising banner 4 needs to be cleaned, the motor 502 can drive the threaded rod 501 to rotate, so that the threaded rod 501 can drive the moving frame 503 to move. At this time, the moving frame 503 will drive the banner cleaning mechanism 6 to move. When the upper end of the L-shaped guide rod 601 moves to the protrusion of the guide slot 103, the L-shaped guide rod 601 will drive the wiping plate 602 to move closer to the advertising banner 4, so that it can contact the advertising banner 4 for cleaning.

[0077] Meanwhile, when the moving frame 503 moves, the squeezing plug 702 will contact the convex and concave plate 104, thereby causing the squeezing plug 702 to move downward, squeezing the gas in the L-shaped tube 701 towards the driving rod 703, thereby pushing the driving rod 703 to move. Then, under the action of the sliding rod 705, it can slide in the inclined guide groove 603, thereby driving the wiping plate 602 to move up and down reciprocally for wiping.

[0078] When the transmission ratchet 505 on the transmission bar 504 contacts the ratchet 102, it will drive the ratchet 102 to rotate, thereby driving the connected worm gear 101 to rotate. The worm gear 101 will drive the limit baffle 302 connected to the worm wheel 303 to rotate, which will drive the friction roller 301 to rotate, and thus drive the advertising banner 4 to rotate, so as to change and display different resource environment pictures.

[0079] This application employs a banner cleaning mechanism, which, when in use, allows the wiping plate to contact the banner under the drive of the transmission mechanism, thereby cleaning the exposed images on the banner and maintaining the promotional display effect of the device.

[0080] When the transmission mechanism drives the banner cleaning mechanism to move and clean, it can also rotate the advertising banner, thereby automatically changing the advertising images of different resources and environments and improving the practicality of the device.

[0081] This invention also provides a method for using a signboard wall to promote resources and the environment, comprising the following steps:

[0082] Step 1: Close and roll the banner 4 printed with resource and environmental pictures onto the friction roller 301 and support plate 304 on the placement frame 3;

[0083] Step 2: Insert the limiting baffle 302 into the friction roller 301 and fix it with screws;

[0084] Step 3: Then push the placement rack 3 to fix the support plate 304 in the placement slot 2; at this time, the promotional content of the banner 4 can be seen through the front opening of the placement slot 2;

[0085] Step 4: When it is necessary to clean the banner 4, start the motor 502 to drive the threaded rod 501 to rotate, so that the threaded rod 501 drives the moving frame 503 to move. At this time, the moving frame 503 will drive the banner cleaning mechanism 6 to move. When the upper end of the L-shaped guide rod 601 moves to the protrusion of the guide groove 103, the L-shaped guide rod 601 will drive the wiping plate 602 to move closer to the banner 4, so that it can contact the banner 4 for cleaning.

[0086] Step 5: When the moving frame 503 moves, the squeezing plug 702 will contact the convex and concave plate 104, causing the squeezing plug 702 to move downward, squeezing the gas in the L-shaped tube 701 towards the driving rod 703, thereby pushing the driving rod 703 to move. Then, under the action of the sliding rod 705, it can slide in the inclined guide groove 603, thereby driving the wiping plate 602 to move up and down reciprocally for wiping.

[0087] Step 6: When the transmission ratchet 505 on the transmission bar 504 contacts the ratchet 102, it will drive the ratchet 102 to rotate, thereby driving the connected worm gear 101 to rotate. The worm gear 101 will drive the limit baffle 302 connected to the worm wheel 303 to rotate, which will drive the friction roller 301 to rotate, and thus drive the advertising banner 4 to rotate, so as to change and display pictures of different resource environments.
