[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] The embodiments of this utility model relate to an elevator call box, such as... Figure 1-8As shown, the device includes a housing 1, which has an open-side structure. The housing 1 is thin and lightweight, with U-shaped and strip-shaped protrusions enhancing its overall strength and structural stability, and making it resistant to bending and torsion. The upper surface of the housing 1 is smooth, while the left and right sides are frosted to improve its aesthetics. A panel 2 is detachably mounted on the lower end of the housing 1. Symmetrically arranged at one end of the panel 2 are downwardly extending latching portions 3, each with a latching groove 4. Both sides of the lower end of the housing 1 have clearance notches 5, with buckles 6 on their sidewalls that engage with the latching grooves 4. The other end of the panel 2 is provided with a hook foot 7, which extends downward and backward. Both ends of the middle part of the housing 1 are provided with slots 8. When the panel 2 is placed on the housing 1, the hook foot 7 is engaged in the slot 8. The lower part of the housing 1 is provided with a control button 9 and a control lock 10. The two control buttons 9 and the control lock 10 are arranged in an up-down arrangement. The upper end of the housing 1 is equipped with a circuit board 11 connected to the control button 9 and the control lock 10. The panel 2 adopts a double detachable connection structure of hook foot and buckle. During installation, the hook foot 7 is first placed in the slot 8 for positioning, and then the buckle 6 is engaged and fixed through the slot 4, which is convenient for disassembly and assembly.

[0027] In this embodiment, as Figure 4 As shown, a U-shaped protrusion 12 is vertically arranged inside the upper end of the housing 1. The space enclosed by the U-shaped protrusion 12 forms a circuit board cavity. The U-shaped protrusion 12 is integrally formed with the housing 1, which increases the structural strength and provides an independent installation space for the circuit board 11, enabling precise positioning.

[0028] In this embodiment, as Figure 4 As shown, two snap-fit ​​protrusions 13 are arranged side by side on one side of the U-shaped protrusion 12. A support part 14 is fixedly arranged on the opposite inner side of the U-shaped protrusion 12. A threaded protrusion 15 is fixedly arranged on the housing 1 inside the U-shaped protrusion 12. Holes that mate with the threaded protrusions 15 are opened at the four corners of the circuit board 11. Through the synergistic effect of the snap-fit ​​protrusions 13, the support part 14 and the threaded protrusions 15, multiple fixation of the circuit board 11 is achieved.

[0029] In this embodiment, as Figure 4 As shown, vertical strip-shaped protrusions 16 are provided on both sides of the control button 9 inside the lower end of the housing 1 to increase the structural strength of the housing 1.

[0030] In this embodiment, as Figure 4 As shown, a plurality of first limiting parts 17 are fixedly provided on the inner side of the strip-shaped protrusion 16 along its length direction, and a second limiting part 18 is provided on one side of the first limiting part 17. The space between the first limiting part 17 and the second limiting part 18 is used to store the wires and realize the orderly arrangement of the wires.

[0031] In this embodiment, as Figure 4 and Figure 7 As shown, a base plate 19 is embedded in the back of the housing 1. Multiple insertion parts 20 are arranged side by side at the lower ends of both sides of the base plate 19. The inner side wall of the housing 1 is provided with a corresponding insertion port 21 that matches the insertion part 20. The base plate 19 and the housing 1 are initially fixed by the insertion.

[0032] In this embodiment, as Figure 7 As shown, the bottom plate 19 is provided with a bent portion 22 at its end, and the bottom of the housing 1 is provided with a bolt 23 that abuts against the bent portion 22. The bottom plate 19 and the housing 1 are fixed by the bolt 23, thereby improving the reliability of the connection.

[0033] In this embodiment, as Figure 7 As shown, the base plate 19 is made of galvanized steel sheet, which has certain corrosion resistance and structural strength, and can extend the service life of the base plate 19.

[0034] In this embodiment, as Figure 6 As shown, the panel 2 is made of brushed stainless steel. The panel 2 has a mounting groove 24 that matches the control button 9 and the control lock 10. The brushed stainless steel material can achieve the function of decoration and beauty, improve the wear resistance and corrosion resistance of the panel 2, and the mounting groove 24 can also ensure the precise installation of the control button 9 and the control lock 10.

[0035] In this embodiment, as Figure 1 As shown, first align the hook 7 at the top of panel 2 with and insert it into the slot 8 of housing 1. Press down the bottom of panel 2 so that the buckle 6 is engaged in the slot 4, completing the engagement and fixation. Place circuit board 11 into the cavity formed by the U-shaped protrusion 12 at the top of housing 1. The engagement protrusion 13 holds one end of circuit board 11. The bottom of circuit board 11 rests on the upper side of support 14 and threaded protrusion 15, preventing circuit board 11 from directly contacting housing 1, thus achieving better heat dissipation. The connection is completed by tightening the bolts and threaded protrusions. Connect circuit board 11 to housing 1 for easy operation; fix control button 9 and control lock 10 to housing 1 through mounting groove 24, and connect the wire of control button 9 to circuit board 11 through the gap between first limiting part 17 and second limiting part 18; insert the plug part 20 of base plate 19 into the plug 21 on the inner side wall of housing 1 to achieve initial fixation; then pass bolt 23 through the threaded hole at the bottom of housing 1 and abut against the bent part 22 of base plate 19 to complete the fixation of base plate 19 to housing 1.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
