[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment: a high-strength back panel suitable for an elevator maintenance box, comprising a main panel 1, a secondary panel 2 is slidably connected to the rear side of the main panel 1, and the size of the entire back panel can be adjusted by sliding the secondary panel 2 on the rear side of the main panel 1 to meet the needs of different installation environments. A positioning rail 7 is provided in the middle of the secondary panel 2, a positioning slider 17 is fixedly connected to the rear side of the main panel 1, and the positioning slider 17 is slidably connected to the middle of the positioning rail 7. The position of the secondary panel 2 is limited by the positioning rail 7 and the positioning slider 17, so that the movement of the secondary panel 2 is more stable.
[0034] Reference Figure 2-Figure 4The main board 1 is fixedly connected with a mounting plate 4 at the top, and a snap-in plate 5 is fixedly connected with the middle of the mounting plate 4. The snap-in plate 5 is slidably connected with the middle of the positioning rail 7. When the secondary board 2 slides, it will also be restricted by the snap-in plate 5 to ensure the stability of the movement of the secondary board 2. The middle of the mounting plate 4 is threadedly connected with a locking bolt 6, and the other end of the locking bolt 6 is in contact with the front side of the secondary board 2. After adjusting the secondary board 2, the position of the secondary board 2 can be temporarily restricted by turning the locking bolt 6 to facilitate the installation of the backboard. The main board 1 and the secondary board 2 are fixedly connected with a grounding terminal 3 on the opposite side, and the grounding terminal 3 is used to achieve electrical connection with the maintenance box. The main board 1 is fixedly connected with a positioning rod 16 at the top, and the secondary board 2 is slidably connected to the periphery of the positioning rod 16. The positioning rod 16 is used to improve the stability of the movement of the secondary board 2 and increase the structural strength of the entire backboard.
[0035] Reference Figure 1-Figure 2 The front sides of the main board 1 and the secondary board 2 are fixedly connected with mounting components; the mounting components include mounting rail 2 10 and mounting rail 1 9, the mounting rail 2 10 is fixedly connected to the front side of the main board 1, and the mounting rail 1 9 is fixedly connected to the front side of the secondary board 2. External electronic components can be installed with the secondary board 2 and the main board 1 respectively through the mounting rail 2 10 and the mounting rail 1 9 to ensure the normal use of the backplane. The front side of the secondary board 2 is fixedly connected with a notch 8, and the mounting rail 1 9 is located in the middle of the notch 8. The mounting rail 1 9 can be stored through the notch 8. When adjusting the position of the secondary board 2, it will not affect the normal installation of the mounting rail 1 9, and reduce the connection corners caused by the adjustment of the position of the secondary board 2, thereby ensuring the tight and effective installation of electronic components.
[0036] Reference Figure 1 , Figure 2 and Figure 5 , the top of the main board component 1 is rotatably connected with a cover plate 11, and a clamping block 12 is fixedly connected to the outer side of the cover plate 11, and a clamping block 2 13 is fixedly connected to the outer side of the mounting plate 4, and the clamping block 12 and the clamping block 2 13 are clamped together. After the position of the secondary plate component 2 is stabilized, the cover plate 11 can be rotated and the clamping block 12 can be clamped with the clamping block 2 13 to block the locking bolt 6 to ensure the flatness of the back plate surface. A baffle 14 is fixedly connected to the outer side of the cover plate 11, and the baffle 14 matches the shape of the notch 8. When the cover plate 11 and the mounting plate 4 are clamped, the baffle 14 can reach the position of the positioning slide rail 7 to block the top of the locking bolt 6 to prevent dust from falling. A baffle 2 15 is fixedly connected to the top of the cover plate 11, and the shape of the baffle 2 15 matches the shape of the mounting guide rail 1 9. The baffle 2 15 can block the top opening of the notch 8 and prevent dust from entering the inside of the notch 8.
[0037] Working principle: When in use, first confirm the position of the bottom grounding terminal 3, then connect the main board 1 to the main frame of the maintenance box, and then pull the secondary board 2 upward to adjust the position of the top grounding terminal 3. After adjusting to the appropriate position, lock the secondary board 2 by turning the locking bolt 6, and connect the secondary board 2 to the main frame of the main board 1. Then, electrically connect the two grounding terminals 3 to the main frame of the maintenance box to complete the installation of the entire backplane. Then install the required electronic components in the middle of the installation guide rail 2 10 and the installation guide rail 1 9 for use. While ensuring normal installation, the size of the backplane can be adjusted according to the size of the installation position, thereby improving the applicability of the backplane and making it more convenient to use. Because the installation guide rail 1 9 is stored in the middle of the notch 8, when the secondary board 2 is extended or retracted, it will not affect the installation guide rail 1 9, so as to achieve the adjustable size of the backplane while ensuring the normal installation of electronic components.
[0038] At the same time, after adjusting the extended length of the secondary plate 2, the cover plate 11 can be rotated toward the mounting plate 4, and after contact, continue to apply force to push the clamping block 12 to the position of the clamping block 2 13, so that the clamping block 12 and the clamping block 2 13 are mutually engaged, thereby completing the connection between the cover plate 11 and the mounting plate 4. At this time, the baffle 14 can cover the top opening of the positioning slide rail 7, and the baffle 2 15 can cover the position of the notch 8, so as to prevent dust and other impurities from entering during use, so as to ensure the normal use of the mounting guide rail 1 9 and the locking bolt 6.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
