[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 2 、 Figure 3 and Figure 4, the utility model provides an embodiment: an elevator car display panel disassembly and assembly structure, comprising: a wall-mounted fixing frame 1 for wall installation, the inner side of the wall-mounted fixing frame 1 is slidably connected to a display mounting frame 2, the front end of the display mounting frame 2 is fixedly connected to a display screen 3, the left side of the wall-mounted fixing frame 1 is slidably connected to a positioning block 5, the left side of the display mounting frame 2 is provided with a positioning notch 19, the outer side of the positioning block 5 is nested in the inner side of the positioning notch 19, the left side of the wall-mounted fixing frame 1 is connected to the rear side of the positioning block 5 by a rebound pressing component, so as to realize the flexible disassembly of the display mounting frame 2, the rebound pressing component includes a fixing plate 9 located on the left side of the wall-mounted fixing frame 1, and the left side of the wall-mounted fixing frame 1 is located at a fixed position The lower side of the fixed plate 9 is slidably connected with an upward push slider 12, and the top of the upward push slider 12 is fixedly connected to the fixed rod 11. The inner rotation of the upward push slider 12 is connected to the traction column 13, and the top of the traction column 13 is rotatably connected to the rear side of the positioning block 5. The top of the upward push slider 12 is located on the outside of the upward push slider 12 and is connected to the bottom end of the fixed plate 9 through the extrusion spring 10. The left notch of the wall-mounted fixing frame 1 is fixedly connected to the limit rod 6, and the middle part of the positioning block 5 is slidably connected to the outside of the limit rod 6. The inner sides of the wall-mounted fixing frame 1 are fixedly connected to the limit strips 15, and the notches on both sides of the display mounting frame 2 are respectively slidably connected to the outside of the limit strips 15, so as to realize the front and rear limit of the display mounting frame 2;

[0027] When performing the disassembly and maintenance operation of the display panel, the operator needs to press the push-up slider 12 upwards. At this time, the fixed rod 11 will slide upwards synchronously, effectively limiting the rising angle of the push-up slider 12. This makes the inner side of the traction column 13 subject to an upward thrust, which in turn causes the angle of the traction column 13 to change, thereby pushing the positioning block 5 to move forward. As the positioning block 5 slides on the outside of the limit rod 6, it successfully breaks away from the constraint of the positioning notch 19. At this time, gently lift the display mounting frame 2, and the display panel can be easily disassembled for maintenance. After the maintenance is completed, lift the push-up slider 12 again, and the display mounting frame 2 will be accurately positioned in the wall-mounted fixing frame 1 through the limit bar 15. Release the pressure on the push-up slider 12, and the positioning block 5 will be re-engaged in the positioning notch 19 to complete the installation of the display mounting frame 2. This process greatly improves the convenience of disassembly of the display panel and improves the maintenance efficiency.

[0028] Reference Figure 1 、 Figure 4 and Figure 5, used for the traction air frame 8 at the bottom end of the wall-mounted fixed frame 1, the right side of the traction air frame 8 is fixedly connected to the cooling fan 7, the top of the traction air frame 8 is fixedly connected to the air inlet frame 14, the inside of the wall-mounted fixed frame 1 is fixedly connected to the cooling frame 16, the front end of the cooling frame 16 is attached to the back side of the display mounting frame 2, and a cooling through groove is installed on the rear side of the display mounting frame 2 to achieve cooling protection of the display screen 3; the cooling through groove includes a cooling groove 20 opened inside the display mounting frame 2, a plurality of air inlet slots 17 are opened in the middle of the rear side of the display mounting frame 2, and external row slots 18 are opened on both sides of the rear end of the display mounting frame 2, and the cooling groove 20 is respectively connected with the external row slots 18 and the air inlet slots 17, and heat exhaust vents 4 are opened on both sides of the wall-mounted fixed frame 1 to improve the exhaust efficiency of the device, and the outside of the air inlet frame 14 passes through the bottom end of the wall-mounted fixed frame 1 and is located on the inner side of the cooling frame 16;

[0029] During normal operation of the display screen 3, the cooling fan 7 is activated to guide external air to flow into the interior of the traction air frame 8. The air is then introduced into the cooling frame 16 through the air inlet frame 14. The cooling frame 16 adopts a design that is wide at the bottom and narrow at the top, so that the airflow is squeezed and accelerated when passing through. This accelerated airflow enters the cooling tank 20 through the air inlet slot 17, and is discharged to the outside through the external discharge slot 18 under the action of wind pressure, thereby achieving effective cooling of the back of the display screen 3. This process significantly improves the cooling efficiency of the device for the display panel and ensures that the service life of the display panel is extended.

[0030] Working principle: When disassembling and inspecting the display panel, the push-up slider 12 is pressed upward, and the fixed rod 11 slides upward to limit the upward sliding angle of the push-up slider 12, thereby generating an upward thrust on the inner side of the traction column 13. The angle of the traction column 13 changes, thereby generating a forward thrust on the positioning block 5, and the positioning block 5 slides on the outside of the limit rod 6, thereby disengaging from the inside of the positioning notch 19. At this time, the display mounting frame 2 is lifted upward to disassemble the display panel. After the inspection is completed, the push-up slider 12 is lifted again, and the display mounting frame 2 passes through the limit of the limit bar 15. Place it inside the wall-mounted fixing frame 1, release the force on the upward push slider 12, and the positioning block 5 is again inserted into the positioning slot 19 to install the display mounting frame 2. When the display screen 3 is in normal use, start the cooling fan 7 to draw the external air into the interior of the traction wind frame 8, and transmit it to the interior of the cooling frame 16 through the air inlet frame 14. The interior of the cooling frame 16 is wide at the bottom and narrow at the top, and the flow air is accelerated by the squeezing of the cooling frame 16, thereby entering the interior of the cooling tank 20 through the air inlet slot 17, and is discharged to the outside through the outer exhaust slot 18 as the wind pressure acts, thereby completing the cooling of the back side of the display screen 3.
