Description

Technical Field

[0001] This invention relates to the field of elevator advertising display screen installation technology, specifically to an elevator advertising display screen installation device. Background Technology

[0002] Elevator advertising is a new type of advertising medium, referring to advertisements produced and displayed on the inner walls of elevators in urban buildings. Elevator advertisements come in various types, primarily in commercial elevators and building elevators. They are mainly installed in the form of picture frames inside the elevator car, or directly on the elevator doors.

[0003] Many elevator advertisements nowadays use networked displays to play ads in real time. Elevator advertising displays are usually installed in two ways. The first method uses expansion bolts to install the back panel on the surface of the elevator car, and then uses the hook holes on the back panel to cooperate with the hooks on the back of the display screen for installation. The second method uses double-sided tape to stick the back panel to the surface of the elevator car. This method does not damage the surface of the elevator wall compared to the first method, so many elevator advertising displays are installed in this way.

[0004] However, when using double-sided adhesive to attach the back panel to the elevator car, it is difficult to ensure that the back panel and the elevator car are level, which means that they are easily pasted crookedly. In addition, it is also easy for the back panel and the elevator car to not be parallel, that is, the surface of the back panel is uneven. Summary of the Invention

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] An elevator advertising display screen installation device, such as Figure 1 , 7 As shown, the system includes a vertical adjustment component and a positioning auxiliary component. The vertical adjustment component is used to adjust whether the installation equipment is vertical, and the positioning auxiliary component is used to limit the position of the display screen back panel, so that the display screen back panel remains stationary during installation, thereby preventing the display screen back panel from being misaligned. The vertical adjustment component includes a mounting frame 10, a rotating frame 11, a connecting rope 12, a calibration block 13, a conical block 14, a worm gear 32, a worm wheel 33, and a first motor 37. The rotating frame 11 is rotatably connected inside the mounting frame 10. The worm wheel 33 is fixedly connected to the bottom of the rotating frame 11 and is fixedly installed at the bottom of the rotating frame 11. The worm wheel 33 meshes with the worm gear 32. The first motor 37 is fixed to the bottom of the mounting frame 10, and the output end of the first motor 37 is fixedly connected to the worm gear 32. One end of the connecting rope 12 is tied to the top of the mounting frame 10, connecting... The other end of the rope 12 is connected to a conical block 14. The calibration block 13 is fixedly installed on the surface of the rotating frame 11. A gap is opened at the center of the calibration block 13. The connecting rope 12 corresponds to the gap. Sensing plates are set on both sides of the gap of the calibration block 13. The sensing plates are electrically connected to the first motor 37. The positioning auxiliary component includes a sliding plate 16, a fixed rail 17, a fixed cylinder 18, a T-shaped plate 19, and a third spring 41. The fixed rail 17 is fixedly installed on the inner wall of the rotating frame 11. The sliding plate 16 is slidably connected to the fixed rail 17. The fixed cylinder 18 is fixedly connected to the sliding plate 16. One end of the T-shaped plate 19 is slidably connected inside the fixed cylinder 18. The other end of the T-shaped plate 19 extends to the outside of the fixed cylinder 18. The display screen backplate is set between multiple T-shaped plates 19. A third spring 41 is set between the fixed cylinder 18 and the T-shaped plate 19.

[0030] Before installing the elevator display screen, the back panel of the display screen and the surface of the elevator car need to be installed first. Then, the elevator advertising display screen is installed by using the hook holes on the back panel and the hooks on the back of the display screen. When installing the back panel of the display screen, the position of the back panel of the display screen can be straightened by the set vertical adjustment component and positioning auxiliary component, so that the back panel of the display screen and the elevator car always remain parallel. Specifically, since the connecting rope 12 is always vertically downward under the action of the cone block 14, if the connecting rope 12 deviates, that is, if the mounting frame 10 and the elevator car are not perpendicular, for example, if the connecting rope 12 deviates to the left, the connecting rope 12 contacts the sensing plate on the left side of the calibration block 13. The sensing plate on the left side transmits the signal to the first motor 37. The first motor 37 starts and drives the worm gear 32 to rotate. The worm gear 32 further drives the worm wheel 33 and the rotating frame 11 to rotate to the right until the rotating frame 11 and the elevator car are perpendicular. Since the positioning auxiliary component is set on the rotating frame 11 and the back panel of the display screen is set on the positioning auxiliary component, the back panel of the display screen and the elevator car remain perpendicular.

[0031] like Figure 2 , 3 As shown in Figure 9, a mounting cylinder 22 is provided at the center of the rotating frame 11. A connecting plate 20 is fixedly provided between the sliding plate 16 and the mounting cylinder 22. A hydraulic rod 31 is fixedly provided on the inner wall of the rotating frame 11. The end of the hydraulic rod 31 is fixedly connected to the mounting cylinder 22. A second motor 38 is fixedly installed inside the mounting cylinder 22. A transmission rod 39 is fixedly connected to the output end of the second motor 38. A pressing rod 21 is fixedly connected to the end of the transmission rod 39 away from the second motor 38.

[0032] When the display screen back panel is adjusted to be perpendicular to the elevator car, the hydraulic rod 31 is activated to drive the sliding plate 16 to move. The sliding plate 16 further drives the T-shaped plate 19 and the display screen back panel to move. As the T-shaped plate 19 gradually comes into contact with the elevator car, the third spring 41 is compressed until the pressing rod 21 comes into contact with the display screen back panel. Then the pressing rod 21 pushes the display screen back panel into contact with the elevator car. Then the second motor 38 is activated to drive the transmission rod 39 and the pressing rod 21 to rotate. The pressing rod 21 continuously presses the display screen back panel, pressing the glue on the display screen back panel and the elevator car together tightly.

[0033] like Figure 1 , 2 As shown, a connecting component is provided below the mounting frame 10. The connecting component includes a mounting plate 1 and a suction cup 15. The suction cup 15 is set on the mounting plate 1 and is attached to the wall to fix the entire installation device. A folding component is provided between the mounting plate 1 and the mounting frame 10.

[0034] like Figure 1As shown, the folding assembly includes a slide rail 2, a push rod 3, a connecting rod 5, a lead screw 6, a fixing block 7, and a support plate 8. The slide rail 2 is fixedly connected to the mounting plate 1. The support plate 8 is rotatably connected to the end of the slide rail 2. One end of the push rod 3 is rotatably connected to the support plate 8, and the other end of the push rod 3 is slidably connected to the slide rail 2. A groove 4 is provided on the outer wall of the slide rail 2, and the push rod 3 is slidably connected in the groove 4. The connecting rod 5 is fixedly connected to the push rod 3. One end of the lead screw 6 is rotatably connected to the connecting rod 5. The fixing block 7 is connected to the surface of the mounting plate 1, and the other end of the lead screw 6 is threadedly connected to the fixing block 7. When the display screen back panel needs to be installed, the lead screw 6 is rotated to move the connecting rod 5. The connecting rod 5 drives the push rod 3 to rotate and open the support plate 8 until the support plate 8 is perpendicular to the mounting plate 1. Then the display screen back panel can be installed. When not in use, the base plate 9 and the support plate 8 can be folded using the above mechanism, thereby reducing the space occupied by the entire device and making it convenient to carry and transport.

[0035] like Figure 3 , 4 As shown, a base plate 9 is fixedly connected to the surface of the support plate 8, and a mounting frame 10 is movably connected to the surface of the base plate 9. The surface of the base plate 9 is provided with a quick-release mechanism for quickly removing the mounting frame 10. The quick-release mechanism includes a positioning block 23, a limiting plate 24, an elastic rope 26, and a pin 40. The positioning block 23 is fixedly connected to the surface of the base plate 9, and the limiting plate 24 and the positioning block 23 are rotatably connected. The surface of the positioning block 23 has a square cavity corresponding to the limiting plate 24. One end of the elastic rope 26 is tied to the top of the positioning block 23. The other end of the rope 26 is tied to the pin 40. The pin 40 is inserted into the top of the positioning block 23 and extends into the square cavity. The surface of the limiting plate 24 is provided with a socket 25 that mates with the pin 40. The quick-release mechanism enables the quick installation and removal of the mounting frame 10. When the mounting frame 10 needs to be removed, the pin 40 is pulled out from the socket 25, and then the limiting plate 24 is rotated to move the limiting plate 24 away from the top of the mounting frame 10 until another socket 25 on the surface of the limiting plate 24 corresponds to the pin 40.

[0036] like Figure 5 , 6As shown, the T-shaped plates 19 are divided into upper and lower groups, with two T-shaped plates 19 in each group. A baffle 28 is slidably connected inside the upper group of T-shaped plates 19, and a first spring 27 is fixedly connected inside the T-shaped plate 19. The first spring 27 and the baffle 28 are fixedly connected. A strip-shaped hole 30 is formed on the surface of the T-shaped plate 19, and the baffle 28 extends into the strip-shaped hole 30. A strip-shaped groove 29 corresponding to the strip-shaped hole 30 is formed on the top of the mounting frame 10. The bottom of the baffle 28 is flush with the bottom of the T-shaped plate 19. The baffle 28 and the T-shaped plate 19 are set to be flush. The function is to prevent the back panel of the display screen from being blocked by the baffle 28. The T-shaped plate 19 is provided with a slot, and the baffle 28 and the slot are slidably connected. With the cooperation of the strip hole 30, the baffle 28 and the first spring 27, the back panel of the display screen passes through the strip groove 29 and the strip hole 30 in sequence during installation, and then contacts and presses the baffle 28, causing the first spring 27 to be compressed, until the back panel of the display screen is placed between the T-shaped plates 19. At this time, the baffle 28 does not contact the back panel of the display screen, and the baffle 28 returns to its original position under the elastic force of the first spring 27.

[0037] like Figure 7 As shown, a support assembly is provided between the rotating frame 11 and the mounting frame 10. The support assembly includes an arc plate 43 and a roller 42. The arc plate 43 is fixedly connected to the bottom of the rotating frame 11, and the roller 42 is rotatably connected inside the arc plate 43 and slides in contact with the bottom of the mounting frame 10. The support assembly facilitates the stable connection between the rotating frame 11 and the mounting frame 10.

[0038] like Figure 2 , 8 As shown, two sets of T-shaped plates 19 are provided to position and support the back panel of the display screen. One set of T-shaped plates 19 has a clamping assembly on its surface. The clamping assembly includes a second spring 34, a fixing cavity 35, and a clamping block 36. The fixing cavity 35 is fixedly connected to the surface of the T-shaped plate 19. The clamping block 36 is slidably connected in the fixing cavity 35 and extends above the T-shaped plate 19. The second spring 34 is fixedly connected in the fixing cavity 35 and fixedly connected to the clamping block 36. A limit groove is provided on the inner wall of the fixing cavity 35. The clamping block 36 is slidably connected in the limit groove.
