Technical Field
[0001] This utility model relates to the field of sheet metal parts for elevator cars, specifically a high-stability sheet metal part for elevator cars. Background Technology
[0002] The elevator car is a box-shaped space used to carry and transport people and goods. The car is generally composed of main components such as the car floor, car walls, car top, and car doors. The car walls, as the inner protective layer of the elevator car, are usually assembled into an integrated car structure by using sheet metal parts processed through shearing, punching / cutting / composite, bending, welding, riveting, splicing, and forming processes. Sheet metal parts are especially essential for the elevator floor control panel.
[0003] In Chinese patent CN202223303595.7, this utility model provides a sheet metal part for an elevator car. The sheet metal frame has two sets of first bending ribs that are symmetrically bent at both ends in the forward and reverse directions. The rib ends of the two sets of first bending ribs are bent in the same direction to form two sets of second bending ribs. The sheet metal frame is pressed and fastened by a reinforcing rib mechanism installed inside its frame through a butt joint. This utility model replaces the traditional method of assembling and fixing two adjacent sheet metal parts using a single fold. The Z-shaped fold formed by the first and second bending ribs has dual assembly and fixing characteristics. On the one hand, it facilitates the assembly of two adjacent sheet metal parts by workers, reducing the labor intensity of the assembly. On the other hand, by using the plate surface support of the two sets of bending ribs, it can increase the contact area between the two adjacent sheet metal parts, thereby improving the stability of the integrated assembly of adjacent sheet metal parts.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example
[0026] Please see Figures 1 to 5 As shown, a high-stability elevator car sheet metal part includes a sheet metal body 1, an elevator control board 2 is disposed in the middle of the sheet metal body 1, and positioning plates 3 are fixedly connected to both sides of the inner wall of the sheet metal body 1. A positioning block 4 is integrally disposed in the middle of the outer wall of the positioning plate 3, and the positioning block 4 is hollow. A positioning spring 5 is fixedly connected to the middle of the inner wall of the positioning block 4. A sealing ring 17 is glued to the outer wall of the elevator control board 2, and the sealing ring 17 is tightly fitted to the inner wall of the sheet metal body 1. In this way, during multiple maintenance, only the four corner mounting screws 9 and fastening screws 13 on both sides of the elevator control board 2 need to be removed, which saves time and effort during disassembly. At the same time, it is easy to adjust the fixing strength of the mounting screws 9 according to the installation position, which has high stability. When the protective frame 12 is fixed, the sealing ring 17 can prevent dust from entering the interior of the sheet metal body 1 through the groove gap. The positioning spring 5 is away from the body. One end of the positioning block 4 is nested with a positioning ring 6, and the end of the positioning ring 6 away from the positioning spring 5 is fixedly connected with a positioning rod 7. The end of the positioning rod 7 away from the positioning ring 6 is integrally provided with a mounting plate 8. When the elevator control board 2 is removed outward, the positioning rod 7 is separated from the positioning ring 6, and the elevator control board 2 can be disassembled. When the elevator control board 2 is installed, the positioning spring 5 can assist in the installation and fixation of the mounting screw 9. The middle position of the mounting plate 8 has a reserved mounting groove, and the mounting screw 9 is connected through the inside of the mounting groove. The end of the mounting screw 9 is threadedly connected with a mounting tube 10, and the end of the mounting tube 10 away from the mounting screw 9 is fixedly connected to the outer wall of the positioning plate 3. The outer wall of the mounting plate 8 is welded with a mounting strip 11. The upper and lower ends of the mounting strip 11 on both sides of the outer wall of the elevator control board 2 are integrally provided with mounting plates 8. The mounting screws 9 at the four corners are removed in sequence, and the mounting screws 9 fix the mounting plate 8 and the mounting tube 10 respectively. Example
[0027] like Figures 1 to 2As shown, a protective frame 12 is fixedly installed on the front of the sheet metal body 1. Fastening screws 13 are threaded through each of the four corners of the protective frame 12 and are connected to the sheet metal body 1 by threads. During maintenance of the elevator control board 2, the fastening screws 13 at the four corners of the protective frame 12 are removed. The protective frame 12 improves the stability and safety of the elevator control board 2 during use, providing greater safety assurance. A first slot 14 is reserved in the middle of the bottom of the protective frame 12, and second slots 15 are reserved at equal intervals above the first slot 14. A third slot 16 is reserved above the second slot 15. (The last sentence appears to be unrelated and possibly a fragment: "Speaker 2...") The speaker 20 is located at the bottom center of the elevator control panel 2, and buttons 19 are evenly spaced above the speaker 20. A display screen 18 is located above the buttons 19. The first slot 14, the second slot 15, and the third slot 16 are respectively matched with the speaker 20, the buttons 19, and the display screen 18, without affecting the normal use of the speaker 20, the buttons 19, and the display screen 18. The speaker 20 is snap-fitted to the first slot 14, and the first slot 14 is recessed. The third slot 16 is snap-fitted to the display screen 18, and the display screen 18 is recessed.

Remove the mounting screws 9 at the four corners in sequence. The mounting screws 9 fix the mounting plates 8 and the mounting tubes 10 respectively. Take the elevator control board 2 outward to separate the positioning rod 7 from the positioning ring 6, and then the elevator control board 2 can be disassembled. When the elevator control board 2 is installed, the positioning spring 5 can assist in the installation and fixing of the mounting screws 9, which improves the installation stability of the sheet metal parts.
[0029] Secondly, when the protective frame 12 is fixed, the sealing ring 17 can squeeze the gaps on all four sides, thus preventing dust from entering the body of the sheet metal part 1 through the groove gaps, and has a certain dustproof function. The first groove 14, the second groove 15, and the third groove 16 respectively match the speaker 20, the button 19, and the display screen 18 without obstruction. The first groove 14 and the third groove 16 are recessed, which can reduce the direct plane being hit by collisions and prevent them from being damaged by external impacts during use.
