Description
Technical Field
[0001] This application relates to the field of advertising machine technology, and in particular to an elevator wall-mounted advertising machine. Background Technology
[0002] Elevators are transportation devices used in buildings to stop at designated floors. Elevators are also places with high passenger flow, so many manufacturers may place advertisements in elevators. As a result, the use of advertising machines is also quite common. Advertising machines are a new generation of intelligent devices that form a complete advertising broadcasting and control system through software control. They can carry out advertising through multimedia materials such as pictures, text, and videos, and allow people to view advertisements in an interactive way.
[0003] In existing technology, most advertising machines installed in elevators are wall-mounted, primarily fixed directly to the inner wall of the elevator using expansion bolts. Because the surface of the elevator advertising machine's display screen easily accumulates dust, fingerprints, stains, and other contaminants, it requires regular cleaning. Cleaning the screen involves maintenance personnel spraying cleaning fluid onto the surface, then using a scraper to scrape off and wipe away the cleaning fluid, thus removing the stains.
[0004] However, existing wall-mounted advertising machines in elevators do not have a collection structure at the bottom to catch the cleaning fluid after it is scraped off. The cleaning fluid flows directly into the elevator car after being scraped off the screen, affecting the cleanliness of the elevator car and creating an extra cleaning workload. There is room for improvement. Utility Model Content
[0005] In order to reduce the occurrence of cleaning fluid scraped off the screen and falling into the elevator car during the cleaning process of the advertising machine, this application provides an elevator wall-mounted advertising machine.
[0006] The elevator wall-mounted advertising machine provided in this application adopts the following technical solution:
[0007] An elevator wall-mounted advertising machine includes an advertising machine body, an installation frame fixedly installed at the bottom of the advertising machine body, a placement frame slidably connected inside the installation frame, a sponge strip detachably installed inside the placement frame, a locking mechanism for locking the placement frame installed on the installation frame, and a cleaning scraper detachably installed on the placement frame.
[0008] By adopting the above technical solution, when maintenance personnel clean the screen of the advertising machine, they can release the placement rack through the locking mechanism, pull the placement rack out of the mounting frame, and expose the sponge strip inside the placement rack below the screen of the advertising machine. Then, the operator can take out the cleaning scraper inside the placement rack, spray cleaning fluid on the surface of the advertising machine screen, and then clean the screen of the advertising machine with the cleaning scraper. During the cleaning process, the cleaning fluid scraped off by the cleaning scraper flows down the screen and is absorbed by the sponge strip below the screen, thus preventing the cleaning fluid scraped off the screen from falling into the elevator car. After the cleaning operation is completed, the operator can take out the sponge strip in the placement slot, place the cleaned sponge strip in the placement rack, clean the cleaning scraper, put the cleaning scraper back into the placement rack, and then lock the placement rack back onto the mounting frame through the locking mechanism.
[0009] Preferably, the mounting frame includes a base plate and two side plates, the two side plates are respectively fixedly mounted on the side wall of the advertising machine body, and a mounting cavity adapted to the mounting frame is formed between the base plate and the bottom of the advertising machine body.
[0010] The placement rack has a placement groove extending axially through it, and the sponge strip can be detachably installed in the placement groove.
[0011] By adopting the above technical solution, the sponge strip is placed in the placement groove. When the operator pulls the placement frame, the placement frame is exposed from the mounting cavity of the mounting bracket, thereby exposing the sponge strip in the placement groove so that it can receive and absorb the cleaning liquid scraped off the screen.
[0012] Preferably, a connecting plate is fixedly connected to the bottom of the placement rack, and an clearance opening adapted to the connecting plate is provided on the bottom plate;
[0013] The mounting bracket is fixedly connected to the bottom of a mounting plate. The locking mechanism includes a locking screw and a locking nut. One end of the locking screw is fixedly connected to the mounting plate. A through hole is provided on the connecting plate for the locking screw to pass through. The locking nut is threaded onto the locking screw. The connecting plate is pressed against the mounting plate and the locking nut.
[0014] By adopting the above technical solution, when it is necessary to fix the placement slot on the mounting cavity, the operator can push the placement frame back into the mounting cavity of the mounting frame, so that the locking screw extends out from the locking hole on the connecting plate. Then, the operator installs the locking nut on the locking screw, so that the connecting plate at the bottom of the placement frame can be connected to the mounting plate at the bottom of the mounting frame. When the screen of the advertising machine needs to be cleaned, the operator can remove the nut and pull the connecting plate to simultaneously drive the placement frame to slide out from the mounting cavity of the mounting frame, thereby exposing the sponge strip in the placement slot.
[0015] Preferably, a limiting strip is fixedly connected to the outer wall surface of the base plate, and the limiting strip covers the opening of the clearance.
[0016] By adopting the above technical solution and setting the limit stop, the maximum sliding distance of the connecting plate can be limited, which can reduce the occurrence of the placement rack completely falling out of the mounting rack.
[0017] Preferably, the placement rack includes an outer plate, and a limiting frame is fixedly connected to the inner wall of the outer plate. An insertion slot adapted to the cleaning scraper is formed between the limiting frame and the inner side wall of the outer plate.
[0018] By adopting the above technical solution, the cleaning scraper can be easily placed by the operator through the insertion port in the limiting frame.
[0019] Preferably, a heat-equalizing film is fixedly connected to the inner wall surface of the mounting cavity.
[0020] By adopting the above technical solution and setting up a heat dissipation film, the heat generated during the operation of the advertising machine can be diffused to the entire mounting frame due to the good thermal conductivity of the heat dissipation film, thus ensuring the heat dissipation effect on the bottom of the advertising machine.
[0021] In summary, the elevator wall-mounted advertising machine of this application has at least one of the following beneficial technical effects:
[0022] 1. When maintenance personnel clean the screen of the advertising machine, the placement rack can be released through the locking mechanism and pulled out of the mounting bracket, so that the sponge strip inside the placement rack is exposed under the screen of the advertising machine. Then, the operator can take out the cleaning scraper inside the placement rack, spray cleaning fluid on the surface of the advertising machine screen, and then the operator can use the cleaning scraper to clean the screen of the advertising machine. During the cleaning process, the cleaning fluid scraped off by the cleaning scraper flows down the screen and is absorbed by the sponge strip under the screen, thus preventing the cleaning fluid scraped off the screen from falling into the elevator car.
[0023] 2. When it is necessary to fix the placement slot to the mounting cavity, the operator can push the placement frame back into the mounting cavity of the mounting frame, so that the locking screw protrudes from the locking hole on the connecting plate. Then, the operator can install the locking nut on the locking screw, so that the connecting plate at the bottom of the placement frame can be connected to the mounting plate at the bottom of the mounting frame. When the screen of the advertising machine needs to be cleaned, the operator can remove the nut and pull the connecting plate to simultaneously drive the placement frame to slide out of the mounting cavity of the mounting frame, thereby exposing the sponge strip in the placement slot.

[0028] The following combination Figures 1-3 This application will be described in further detail.
[0029] Example 1
[0030] This application discloses an elevator wall-mounted advertising machine. (See also...) Figure 1 and Figure 2 It mainly includes an advertising machine body 1, an installation frame 2 fixedly installed at the bottom of the advertising machine body 1, a placement frame 3 slidably connected inside the installation frame 2, a sponge strip 4 detachably installed inside the placement frame 3, a locking mechanism 5 for locking the placement frame 3 installed on the installation frame 2; and a cleaning scraper 6 detachably installed on the placement frame 3.
[0031] By adopting the above technical solution, when maintenance personnel clean the screen of the advertising machine, they can release the placement rack 3 through the locking mechanism 5, pull the placement rack 3 out of the mounting rack 2, and expose the sponge strip 4 inside the placement rack 3 below the screen of the advertising machine.
[0032] The operator can then remove the cleaning scraper 6 from the rack 3, spray cleaning fluid onto the screen surface of the advertising machine, and then clean the screen of the advertising machine with the cleaning scraper 6. During the cleaning process, the cleaning fluid scraped off by the cleaning scraper 6 flows down the screen and is absorbed by the sponge strip 4 below the screen, thus preventing the cleaning fluid scraped off the screen from falling into the elevator car.
[0033] After the cleaning operation is completed, the operator can take out the sponge strip 4 from the placement slot, place the cleaned sponge strip 4 in the placement rack 3, clean the cleaning scraper 6, put the cleaning scraper 6 back into the placement rack 3, and then lock the placement rack 3 back onto the mounting rack 2 through the locking structure.
[0034] Because the sponge strip 4 has good water absorption properties, it can quickly absorb the cleaning liquid after it is scraped off from the advertising machine body 1, and recycle and clean the sponge strip 4, so that the sponge strip 4 can be reused.
[0035] It should be noted that in this embodiment, a soft silicone part is fixedly connected to the cleaning scraper 6. The soft silicone part can better fit with the screen on the advertising machine body 1 during the cleaning process and scrape off the cleaning liquid, dust, stains and other substances on the screen of the advertising machine body 1. Moreover, since the soft silicone part is relatively soft, it can reduce the occurrence of screen scratches during the cleaning operation on the advertising machine body 1.
[0036] Reference Figure 1 The mounting frame 2 includes a base plate and two side plates. The two side plates are fixedly installed on the side wall of the advertising machine body 1 by welding. An installation cavity 21 adapted to the placement frame 3 is formed between the base plate and the bottom of the advertising machine body 1. A placement groove is provided through the placement frame 3 along the axial direction. The sponge strip 4 can be detachably installed in the placement groove.
[0037] The sponge strip 4 is placed in the placement groove. When the operator pulls the placement frame 3, the placement frame 3 is exposed from the mounting cavity 21 of the mounting frame 2, thereby exposing the sponge strip 4 in the placement groove so that the sponge strip 4 can receive and absorb the cleaning liquid scraped off the screen.
[0038] The bottom of the placement rack 3 is fixedly connected to a connecting plate 32, and the bottom plate has an clearance opening 23 that is adapted to the connecting plate 32; the bottom of the mounting rack 2 is fixedly connected to a mounting plate 22, and the locking mechanism 5 includes a locking screw 51 and a locking nut 52. One end of the locking screw 51 is fixedly connected to the mounting plate 22, and a through hole for the locking screw 51 to pass through is provided on the connecting plate 32. The locking nut 52 is threadedly connected to the locking screw 51, and the connecting plate 32 is pressed between the mounting plate 22 and the locking nut 52.
[0039] When it is necessary to fix the placement slot to the mounting cavity 21, the operator can push the placement frame 3 back into the mounting cavity 21 of the mounting frame 2, so that the locking screw 51 extends out from the locking hole on the connecting plate 32. Then, the operator installs the locking nut 52 on the locking screw 51, so that the connecting plate 32 at the bottom of the placement frame 3 can be connected to the mounting plate 22 at the bottom of the mounting frame 2.
[0040] When the screen of the advertising machine needs to be cleaned, the operator can remove the nut and pull the connecting plate 32 to simultaneously drive the placement rack 3 out of the mounting cavity 21 of the mounting rack 2, thereby exposing the sponge strip 4 in the placement groove.
[0041] Reference Figure 1 and Figure 2A limiting strip 24 is fixedly connected to the outer wall surface of the base plate, and the limiting strip 24 covers the opening of the clearance opening 23. By setting the limiting strip 24, the maximum sliding distance of the connecting plate 32 can be limited, which can reduce the occurrence of the placement rack 3 completely falling out of the mounting rack 2.
[0042] Reference Figure 2 and Figure 3 The placement rack 3 includes an outer plate, the outer side wall of which protrudes from the opening of the mounting cavity 21. A limiting frame 33 is fixedly connected to the inner wall of the outer plate, and an insertion slot adapted to the cleaning scraper 6 is formed between the limiting frame 33 and the inner side wall of the outer plate. The cleaning scraper 6 can be easily placed by the operator through the insertion slot in the limiting frame 33.
[0043] The implementation principle of the elevator wall-mounted advertising machine proposed in this application embodiment is as follows: When the maintenance personnel clean the screen of the advertising machine, the placement frame 3 can be released through the locking mechanism 5, and the placement frame 3 can be pulled out from the mounting frame 2, so that the sponge strip 4 inside the placement frame 3 is exposed below the screen of the advertising machine; then the operator can take out the cleaning scraper 6 inside the placement frame 3, spray cleaning liquid on the surface of the screen of the advertising machine, and the operator can clean the screen of the advertising machine through the cleaning scraper 6. During the cleaning process, the cleaning liquid scraped off by the cleaning scraper 6 flows down from the screen and is absorbed by the sponge strip 4 below the screen, thus preventing the cleaning liquid scraped off the screen from falling into the elevator car.
[0044] Example 2
[0045] In this embodiment, a heat-spreading film is fixedly connected to the inner wall surface of the mounting cavity. Part of the heat-spreading film is fixed to the bottom of the advertising machine body by adhesive bonding.
[0046] By using a heat dissipation film, which has excellent thermal conductivity, the heat generated during the operation of the advertising machine can be diffused throughout the mounting frame, ensuring effective heat dissipation at the bottom of the advertising machine.
[0047] It should be noted that the heat-spreading film used in this embodiment is a graphite heat-spreading film, which has good thermal conductivity and heat spreader effect. It is adhered to the inner wall of the mounting cavity by adhesive. In some other embodiments, other film materials with good thermal conductivity and heat spreader performance can be used according to actual needs, which will not be limited or described here.
[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
