[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model is an elevator external call box that is easy to disassemble and maintain. The external call box mainly includes a base box 1 fixed to a wall or other mounting surface and a panel 2 covering the opening of the base box 1.

[0029] The bottom box 1 is roughly rectangular, and its bottom plate is provided with a mounting structure for fixing it to the mounting surface.

[0030] In this embodiment, the mounting structure consists of multiple parallel strip grooves 101.

[0031] During installation, screws can be passed through these slots 101 and screwed into the wall. The design of the slots 101 allows the base box 1 to be finely adjusted up or down or left or right during installation, which is convenient for alignment and leveling.

[0032] To accommodate the elevator's control and display cables, an inlet structure is provided on the base plate of the junction box 1. Specifically, the inlet structure is a through hole 102 on the outer side of the slot 101. This design allows the cable to enter the junction box from the side, avoiding the interference with the mounting screws that might occur if the hole is directly drilled in the base plate.

[0033] The opening of the bottom box 1 has a first connecting structure and a second connecting structure with different structures on its two opposite sides.

[0034] Specifically, the first connecting structure is a curved portion formed on the upper side of the opening of the bottom box 1 and bent inward. Furthermore, to improve installation stability, a limiting groove 105 is also provided on the opposite side.

[0035] The second connecting structure is located on the edge 103 at the opening of the bottom box 1. The edge 103 extends upward from the opening of the bottom box 1, and its length direction is consistent with the side. A groove 104 is formed on the edge 103 along its length direction.

[0036] The panel 2, which mates with the base box 1, has a third connecting structure and a fourth connecting structure on its inner side (i.e., the side facing the base box).

[0037] The fourth connecting structure is used to achieve a sliding guide engagement with the second connecting structure of the base box 1. It includes a surrounding plate 201 extending downward from the bottom surface of the panel 2. The outer side of the surrounding plate 201 is provided with a column 202 that corresponds to and is slidably engaged with the sliding groove 104. Preferably, the column 202 can be cylindrical or a guide block.

[0038] The third connecting structure is used to achieve a snap-fit ​​engagement with the first connecting structure of the bottom box 1. It includes an elastic element 3 installed on the inside of the panel 2. In order to provide a mounting base for the elastic element 3, an extension plate 203 extending toward the inside of the bottom box 1 is provided on the bottom surface of the panel 2, and the elastic element 3 (such as a spring clip, metal spring sheet, etc.) is fixedly installed on this extension plate 203.

[0039] To ensure a precise fit and good seal between panel 2 and base box 1, enclosure 201 fits inside body 103. Both enclosure 201 and body 103 are designed as "U"-shaped structures with three sides, nested together. Extension plate 203 is located inside the "U"-shaped opening formed by enclosure 201. In addition, as part of the third connecting structure, a protruding rib 204 is provided on the outer side of enclosure 201 to engage with limiting groove 105. This protruding rib 204 engages with limiting groove 105 when the panel is installed in place, providing further limiting and anti-loosening functions.

[0040] During installation:

[0041] First, fix the bottom box 1 to the predetermined position on the wall with screws and the strip 101, and then connect the elevator cable into the bottom box through the through hole 102.

[0042] Tilt panel 2 and align the column 202 on the lower side of panel 2 with the upper entrance of the groove 104 on the lower side of the body 103 of the base box 1.

[0043] Push panel 2 to slide column 202 to the end of slide groove 104. At this time, the protruding rib 204 on the outer side of enclosure 201 also engages in limiting groove 105.

[0044] Press the upper part of panel 2 towards the wall so that the end of the elastic element 3 on the inner side of panel 2 passes over the curved part on the upper side of the base box 1 and forms a snap-fit ​​with it. At this time, panel 2 is firmly fixed to the base box 1.

[0045] During disassembly and maintenance:

[0046] Push the panel 2 so that it moves toward the elastic member 3, compressing the elastic member 3, so that the column 202 slides to the opening of the slide groove 104, and at the same time the protruding edge 204 on the outside of the enclosure 201 disengages from the limiting groove 105.

[0047] Then tilt panel 2 outwards to completely remove it for maintenance or replacement of internal components.
