Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a modular maintenance and operation device for elevators. Background Technology

[0002] For elevator maintenance control devices, maintenance buttons are typically installed directly on the cabinet. These buttons are installed and wired together with the electrical cabinet during the workshop installation. However, because the electrical cabinet requires numerous wiring connections, incorrect wiring of the maintenance buttons is prone to occur. Furthermore, modular stocking cannot be done in advance, hindering production efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to propose a modular maintenance and operation device for elevators. This device adopts a modular design and can be directly embedded into the control cabinet door, facilitating workshop installation and wiring, improving assembly efficiency, and reducing wiring error rates.

[0004] The technical solution of this utility model is implemented as follows: a modular maintenance operation device for elevators, including a housing, a first button switch, and a second button switch;

[0005] The box body is open at both ends, and a border is provided around one of the open ends on the outside of the box body.

[0006] The side of the box body is formed with several snap-fit ​​parts; each snap-fit ​​part has a fixed end that is fixedly connected to the box body, and a free end that moves in the inward and outward directions of the box body; the free end of the snap-fit ​​part is set facing the frame, and a limit gap is formed between the two.

[0007] The box body has an assembly plate inside; the assembly plate has several first through holes; the first button switch is detachably inserted and fixed in the first through holes; the assembly plate has several recesses; the bottom of the recesses has a second through hole; the second button switch is detachably inserted and fixed in the second through hole.

[0008] Furthermore, the box body, frame, buckle, and assembly plate are integrally formed.

[0009] Furthermore, the latching portion is arranged on both sides of the box body in the width direction.

[0010] Furthermore, the buckle portion has a guide slope on the side facing the outside of the box; the guide slope extends from the fixed end of the box to the free end and gradually moves away from the outer side of the box.

[0011] Furthermore, the latching portion has an end face formed on the free end; the end face and the guide slope are perpendicular to each other, and the two are smoothly connected.

[0012] Furthermore, the first button switch is an up button switch and / or a down button switch.

[0013] Furthermore, the second push-button switch is an emergency stop push-button switch and / or a maintenance rotary switch.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] This invention utilizes the cooperation of a frame and a snap-fit ​​mechanism to create a limiting gap between them. When the housing is installed on the control cabinet door, the door is confined within this limiting gap, allowing the housing to be securely installed. Several first and second through holes are machined on the assembly plate to facilitate the assembly of different types of first and second push-button switches into the housing, resulting in a modular structure. This combination of methods, employing a modular design, allows the overall structure to be directly embedded into the control cabinet door, facilitating workshop installation and wiring, improving assembly efficiency, and reducing wiring errors.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0025] like Figure 1-6 The diagram shows a modular maintenance operation device for an elevator as described in this embodiment. This modular maintenance operation device is located on the control cabinet door. The device includes a housing 1, a first push-button switch 3, and a second push-button switch 4. The housing 1 has an internal cavity with open top and bottom ends. A frame 11 is formed around the outer perimeter of the housing 1 around the top opening. The frame 11 protrudes outwards from the sides of the housing 1. Several latching portions 12 are formed on the sides of the housing 1. Each latching portion 12 has a strip-shaped structure with a fixed end and a free end. The fixed end of the latching portion 12 is fixedly connected to the housing 1, and the free end of the latching portion 12 can move in the inward and outward directions of the housing 1. The free end of the latching portion 12 faces the frame 11, forming a limiting gap 13 between them. This limiting gap 13 is adapted to the thickness of the control cabinet door. Through this structural design, a window is pre-machined on the control cabinet door. The box 1 is inserted into the window, and the edge of the window is engaged in the limiting gap 13 by the retraction and rebound of the buckle part 12, thereby realizing the installation and fixation of the box 1.

[0026] Specifically, the aforementioned latching portions 12 are arranged on both sides of the box body 1 in the width direction. A guide slope 121 is machined on the side of the latching portion 12 facing the outer side of the box body 1. The guide slope 121 extends from the fixed end of the box body 1 to the free end, gradually moving away from the outer side of the box body 1. When the box body 1 is inserted into the cabinet door of the control cabinet, the guide slope 121 contacts the cabinet door, allowing the latching portion 12 to pass smoothly. The aforementioned latching portion 12 has an end face formed on the free end. This end face forms a limiting gap 13 with the frame 11, and the end face and the guide slope 121 are perpendicular to each other, with a smooth transition between them. When the box body 1 is installed into the cabinet door of the control cabinet, this end face and the frame 11 abut against the opposite sides of the cabinet door.

[0027] An assembly plate 2 is fixed inside the housing 1. Several first through holes 14 are machined on the assembly plate 2. A first push-button switch 3 can be inserted into the first through holes 14, and a first retaining ring 31 is threaded onto the first push-button switch 3 to detachably fix the first push-button switch 3 to the assembly plate 2. Several recesses 15 are machined on the assembly plate 2, such that the bottom surface of the recesses 15 is recessed a certain distance below the surface of the assembly plate 2. A second through hole 16 is machined at the bottom of the recess 15. A second push-button switch 4 can be inserted into the second through hole 16, and a second retaining ring 41 is threaded onto the second push-button switch 4 to detachably fix the second push-button switch 4 to the assembly plate 2. The first push-button switch 3 and the second push-button switch 4 described above are conventional components of the prior art, and their corresponding first retaining rings 31 and 41 are also prior art. The first push-button switch 3 can be an up push-button switch, a run push-button switch, and / or a down push-button switch, selected according to actual needs. The second push-button switch 4 is an emergency stop push-button switch and / or a maintenance rotary switch, which can be selected according to actual needs.

[0028] By rationally designing the depth of the assembly plate 2 within the box 1 and the depth of each cavity 15, the head of each first button switch 3 after installation is not higher than the frame 11, while the head of the emergency stop button switch is higher than the frame 11, so that the head of the maintenance rotary switch is not higher than the frame 11.

[0029] In this embodiment, the aforementioned box body 1, frame 11, buckle part 12, and assembly plate 2 are integrally formed and are made of ABS material with a flame retardant rating of V0.

[0030] In practical use, each first button switch 3 is inserted into the first through hole 14 and locked onto the assembly plate 2 by the first fixing ring 31. Similarly, each second button switch 4 is inserted into the second through hole 16 and locked onto the assembly plate 2 by the second fixing ring 41, thus forming a modular structure. The housing 1 is then installed onto the control cabinet door. When the housing 1 is installed onto the control cabinet door, the snap-fit ​​part 12 retracts and springs back, causing the control cabinet door to snap into the limiting gap 13, thereby achieving the installation and fixation of the housing 1. Finally, the connecting cables are connected to the contacts 5 of each first button switch 3 and second button switch 4. This combination of methods, employing a modular design, allows the entire structure to be directly embedded into the control cabinet door, facilitating workshop installation and wiring, improving assembly efficiency, and reducing wiring error rates.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
