Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a power supply expansion wiring port installed at the top of an elevator. Background Technology

[0002] With the continuous improvement of the intelligence and informatization of elevators, the number of electronic devices that need to be installed and used inside the elevator car is increasing, such as monitoring cameras, multimedia displays, emergency call devices, lighting fixtures, advertising light boxes, and sensors. To meet the power supply needs of these devices, existing elevators generally have power supply expansion wiring ports installed in the top area of ​​the car (i.e., the car top). These ports usually provide a standardized power interface (such as an AC 220V socket or DC terminal block), allowing maintenance personnel or construction parties to conveniently provide power to the new equipment without having to directly run complex wiring from the elevator machine room or the bottom of the shaft. This greatly simplifies the equipment installation process, shortens the construction time, and significantly improves the convenience of elevator function expansion.

[0003] However, the installation and subsequent maintenance and replacement of the power supply extension wiring ports set on the car top in the existing technology are generally inconvenient. The common port structure is often rigidly fixed to the car top bracket or sheet metal by welding, riveting, or multiple fasteners (such as bolts). This fixing method makes it extremely cumbersome to disassemble and replace the port once it is installed. It requires the use of special tools (such as welding guns, wrenches, etc.), consumes a lot of time, and is prone to damaging the car top structure. In addition, the port is usually designed in a small space inside the car top, which makes the maintenance passage obstructed, further increasing the difficulty and risk of maintenance operations. When the port must be replaced due to aging, damage, or the need for upgrading, the elevator often needs to be shut down for a long time, which seriously affects the normal use efficiency of the elevator and the user experience.

[0004] Therefore, how to provide a power supply extension wiring port installed at the top of the elevator is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a power supply extension wiring port installed at the top of the elevator, which solves the problems mentioned in the background art.

[0006] According to an embodiment of the present invention, a power supply extension wiring port is provided on the top of the elevator interior, including a car and a wiring port body. A mounting bracket is provided on the top of the inner wall of the car body, and a limiting member is provided on the top of the inner wall of the car body at the position corresponding to the mounting bracket. Positioning plates are provided at both ends of the wiring port body. One positioning plate is movably inserted into the interior of the mounting bracket, and one end of the other positioning plate is movably connected to the side of the limiting member.

[0007] An elastic pad is provided on the inner wall of the mounting bracket, and the positioning plate is located at one end inside the mounting bracket and is movably connected to the surface of the elastic pad.

[0008] The limiting component includes a movable groove, a limiting rod, and a transverse strut. The movable groove is located at the top of the inner wall of the car body, near the positioning plate. The limiting rod is movably connected inside the movable groove, and the bottom end of the limiting rod extends out of the movable groove and movably fits against the end face of the positioning plate. The transverse strut is movably connected to the bottom end of the limiting rod and is perpendicular to the limiting rod. The top of the transverse strut is movably connected to the lower surface of the positioning plate.

[0009] The top of the inner wall of the car is provided with a placement slot that communicates with the movable slot at the position corresponding to the movable slot, and the size of the placement slot matches the size of the horizontal strut.

[0010] The end face of the horizontal support rod is provided with a protrusion, and the side of the limiting rod is provided with a storage groove corresponding to the position of the protrusion.

[0011] The limiting component also includes a guide groove, a spring, an extrusion head, and an extrusion groove. The guide groove is formed on the inner wall of the movable groove and is perpendicular to the movable groove. The spring and the extrusion head are both movably connected inside the guide groove. The extrusion groove is formed on the side of the limiting rod at the position of the extrusion head. One end of the spring is movably connected to one end of the extrusion head, and the other end of the extrusion head is movably inserted into the extrusion groove.

[0012] The beneficial effects of this utility model are:

[0013] The positioning plate and mounting bracket adopt a movable plug-in design, which, together with the multi-directional movable connection of the limiting component, allows for quick installation or removal of the wiring port without tools, adapting to the expansion needs of different models of equipment.

[0014] The elastic pads cushion the vibrations during car operation, preventing the positioning plate from hard contacting and wearing the card seat. The springs continuously press the extrusion head into the extrusion groove of the limit lever, forming a self-locking force while giving the limit lever an upward force, so that the horizontal support rod drives the positioning plate to stably fit against the top of the inner wall of the car, effectively resisting the displacement of components caused by elevator vibration.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] refer to Figure 1-3 In this embodiment, the car body 1 and the wiring port body 2 are included. The top of the inner wall of the car body 1 is provided with a mounting bracket 3. The top of the inner wall of the car body 1 is provided with a limiting member 4 at the position corresponding to the mounting bracket 3. The two ends of the wiring port body 2 are respectively provided with positioning plates 5. One positioning plate 5 is movably inserted into the inside of the mounting bracket 3, and one end of the other positioning plate 5 is movably connected to the side of the limiting member 4.

[0022] refer to Figure 1-3 In this embodiment, an elastic pad 6 is provided on the inner wall of the mounting base 3, and the end of the positioning plate 5 located inside the mounting base 3 is movably connected to the surface of the elastic pad 6.

[0023] The wiring port body 2 is compressed by the elastic pad 6, which improves the stability of the entire wiring port body 2 during installation.

[0024] refer to Figure 1-3 In this embodiment, the limiting member 4 includes a movable groove 7, a limiting rod 8, and a transverse strut 9. The movable groove 7 is located at the top of the inner wall of the car body 1 near the positioning plate 5. The limiting rod 8 is movably connected inside the movable groove 7, and the bottom end of the limiting rod 8 extends out of the movable groove 7 and movably fits against the end face of the positioning plate 5. The transverse strut 9 is movably connected to the bottom end of the limiting rod 8 and is perpendicular to the limiting rod 8. The top of the transverse strut 9 is movably connected to the lower surface of the positioning plate 5. A placement groove 10 is provided at the top of the inner wall of the car body corresponding to the movable groove 7, and the size of the placement groove 10 matches the size of the transverse strut 9.

[0025] refer to Figure 1-3 In this embodiment, the end face of the horizontal support rod 9 is provided with a protrusion 11, and the side of the limiting rod 8 is provided with a storage groove corresponding to the position of the protrusion 11.

[0026] This is used to store the protrusion 11, preventing the horizontal support rod 9 from extending after moving and affecting the removal of the wiring port body 2.

[0027] refer to Figure 1-3 In this embodiment, the limiting member 4 also includes a guide groove 12, a spring member 13, an extrusion head 14, and an extrusion groove 15. The guide groove 12 is opened on the inner wall of the movable groove 7 and is perpendicular to the movable groove 7. The spring member 13 and the extrusion head 14 are both movably connected inside the guide groove 12. The extrusion groove 15 is opened on the side of the limiting rod 8 at the position of the extrusion head 14. One end of the spring member 13 is movably connected to one end of the extrusion head 14, and the other end of the extrusion head 14 is movably inserted into the inside of the extrusion groove 15.

[0028] The working principle of this utility model is as follows:

[0029] During installation, first insert the positioning plate 5 at one end of the wiring port body 2 into the mounting bracket 3 at the top of the car 1. The elastic pad 6 on the inner wall of the bracket compensates for tolerances and buffers vibrations. Then, push the positioning plate 5 at the other end so that its side is close to the limiting member 4. Pull the transverse strut 9 so that it causes the limiting rod 8 to move down along the movable groove 7. The limiting rod 8 abuts against the end face of the positioning plate 5, cooperating with the mounting bracket 3 to pre-position the wiring port body 2. Simultaneously, move the transverse strut 9 laterally so that it is locked at the bottom of the positioning plate 5, thus preventing the wiring port body 2 from falling. During the locking process, the spring member 13 in the guide groove 12 pushes the pressing head 14 to embed into the limiting member. The compression groove 15 of the limit lever 8 generates a continuous pre-tightening force, ensuring that the limit lever 8 cannot spring back. Moreover, under compression, the limit lever 8 will have an upward force, causing it to push the transverse strut 9 upward. The upward movement of the transverse strut 9 will cause the positioning plate 5 to fit tightly against the top position of the inner wall of the car 1, improving the installation stability of the wiring port body 2. When disassembling, the transverse strut 9 is moved in the opposite direction to separate it from the positioning plate 5, and then the limit lever 8 is pushed upward to cause the transverse strut 9 to be stored inside the placement groove 10. The entire process is achieved through the combination of mechanical interlocking and elastic pre-tightening, realizing the stable power supply expansion interface function under vibration environment.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
