Description

Technical Field

[0001] This utility model relates to the field of elevator shaft lighting technology, and more specifically, to an elevator shaft lighting device. Background Technology

[0002] In existing elevator shaft lighting devices, shaft lights are important equipment for ensuring the safety of elevator maintenance personnel and daily maintenance. Their stability and reliability are of paramount importance. However, the current mainstream shaft lighting design has certain defects in the way the bulbs are fixed. Specifically, most shaft lights have a protective frame on the outside of the bulb, which is intended to protect the bulb from external physical damage and extend its service life. However, the protective frame is often fixed with multiple bolts. Although this ensures a stable connection between the protective frame and the bulb to a certain extent.

[0003] While bolt-fixing provides a secure connection, it requires maintenance personnel to disassemble and reassemble the protective frame using tools when a bulb needs replacement, a cumbersome and time-consuming process. Therefore, we propose an improved elevator shaft lighting device. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] For an example, please refer to... Figures 1-5An elevator shaft lighting device includes a light box 1, a lamp holder 101 connected to the bottom of the light box 1, a bulb body 102 connected to the lamp holder 101, a protective structure 2 provided at the bottom of the light box 1, the protective structure 2 including a connecting ring 201 that fits against the bottom of the light box 1, a plurality of protective rods 202 fixedly connected to the bottom of the connecting ring 201, the bulb body 102 located between the plurality of protective rods 202, a reinforcing ring 203 fixedly connected between the plurality of protective rods 202, a plurality of sliding grooves 204 and a plurality of through openings 205 provided on the connecting ring 201, the plurality of through openings 205 respectively connecting to the plurality of sliding grooves 204. A limiting rod 206 is inserted into the sliding groove 204. The bottom end of the limiting rod 206 is fixedly connected to a baffle 207 located below the connecting ring 201. The top end of the limiting rod 206 is fixedly connected to the bottom of the light box 1. By inserting the limiting rod 206 into the sliding groove 204 and combining it with the baffle 207 to limit the connecting ring 201, the installation of the protective structure 2 is realized. When disassembling, the reinforcing ring 203 is rotated so that the limiting rod 206 enters the through 205. Then, the reinforcing ring 203 is pulled away from the light box 1 to remove the protective structure 2, the reinforcing ring 203, and the protective rod 202, thereby facilitating the replacement of the bulb body 102.

[0031] Furthermore, the diameter of the baffle 207 is smaller than the diameter of the limiting rod 206, and the diameter of the baffle 207 is smaller than the size of the through 205, so that the baffle 207 can pass through the through 205 but cannot pass through the slide groove 204, thereby enabling the baffle 207 to limit the connecting ring 201.

[0032] Furthermore, a limiting hole 213 is provided at the bottom of the light box 1, and a limiting component is provided on one of the protective rods 202. The limiting component is connected to the limiting hole 213, and the limiting component and the limiting hole 213 cooperate with each other to limit the rotation of the connecting ring 201.

[0033] Furthermore, the limiting component includes a chamber 209 formed in one of the protective rods 202 and a notch 208 formed on the protective rod 202 and communicating with the chamber 209. A push plate 210 is slidably connected between the notch 208 and the chamber 209. A plug rod 211 is fixedly installed on the top of the push plate 210. The top end of the plug rod 211 passes through the connecting ring 201 and is inserted into the limiting hole 213. The insertion of the plug rod 211 and the limiting hole 213 can limit the rotation of the connecting ring 201.

[0034] Furthermore, a spring 212 located inside the chamber 209 is fitted on the outer surface of the insertion rod 211. The two ends of the spring 212 are fixedly connected to the chamber 209 and the push plate 210, respectively.

[0035] Furthermore, a power interface 104 is provided on the side of the light box 1, and a switch 103 is connected between the power interface 104 and the lamp holder 101. The switch 103 is installed on the outer surface of the light box 1 and is used to control the lighting of the bulb body 102.

[0036] Furthermore, a mounting structure is provided at the top of the light box 1 for mounting the light box 1.

[0037] Furthermore, the installation structure includes a handle 3 fixedly installed on the top of the light box 1. A connecting seat 301 is fixedly installed on the top of the handle 3. An insertion port 302 is provided on the connecting seat 301. An insertion plate 305 is inserted into the inner wall of the insertion port 302. A fixing seat 304 is fixedly connected to the bottom end of the insertion plate 305. The fixing seat 304 is used to install into the elevator shaft. The insertion of the insertion plate 305 into the insertion port 302 realizes the suspension installation of the connecting seat 301, thereby realizing the suspension installation of the light box 1. After the insertion plate 305 is separated from the insertion port 302, the handle 3 can be held to move the light box 1 so that it can be removed for use when in the elevator shaft.

[0038] Furthermore, the mounting base 304 has several mounting holes 306, which are used for mounting the mounting base 304. Expansion bolts can be used to pass through the mounting holes 306 to fix the mounting base 304 in the elevator shaft.

[0039] Furthermore, the insert plate 305 has a through hole 307, and the connecting seat 301 is threaded with a hand-tightening bolt 303. One end of the hand-tightening bolt 303 is inserted into the socket 302 and connected to the through hole 307. The through hole 307 and the hand-tightening bolt 303 cooperate to fix the insert plate 305 after it is connected to the socket 302.

[0040] The elevator shaft lighting device provided by this utility model is used as follows:

[0041] During installation, fix the mounting base 304 in the elevator shaft, insert the socket 302 into the socket plate 305, and turn the hand-tightening bolt 303 to connect the hand-tightening bolt 303 to the through hole 307.
