Abstract

[Problem] To provide a lamp lighting device that can be quickly removed. [Solution] A lamp lighting device 100 comprises a base 10, a lamp assembly 20, a locking assembly, and a locking plate, wherein the lamp assembly includes a base plate and a detachably connected lampshade. The locking assembly is located on the back surface of the base plate, and a torsion spring is wound around a support rod and has a first elastic arm and a second elastic arm with engaging retaining parts. The locking plate is provided on the base and has strip-shaped grooves at both ends from which two elastic arms protrude. During assembly, the engaging retaining parts elastically open and engage with the edge of the locking plate to achieve fixation, and during disassembly, the distal ends of the two elastic arms are brought closer together by pulling the lamp assembly vertically, the engaging retaining parts are released and disassembly is completed. This enables quick disassembly and assembly without tools and greatly improves maintenance efficiency. [Selection Diagram] Figure 1

Description

This application relates to the field of lamps, and more particularly to lamp lighting devices. In the field of lighting technology, lamps are essential equipment for daily life and industrial production. After a certain period of use, components such as lampshades and light sources require cleaning, replacement, or repair due to dust accumulation, light output reduction, and damage. Currently, commercially available lamps employ several typical forms of removable structures, each with its own inherent drawbacks. The most traditional is the screw-fastening method, where the lamp assembly is locked and secured to the base with multiple screws. While this method ensures a secure connection, removal requires specialized tools such as screwdrivers, resulting in a cumbersome operation, increased maintenance time and labor costs, and even greater inconvenience and safety risks during work at heights. Furthermore, frequent tightening of the screws can strip the threads, potentially damaging the connection structure. Therefore, there is a need for a lamp lighting system that can be quickly removed.

The embodiments of this application will be described below with reference to the drawings of the embodiments. It goes without saying that the embodiments described are only a part of the embodiments of this application, and not all of them. Furthermore, when one component is considered to be "connected" to another, that configuration may be directly connected to the other component, or an intermediary component may be present simultaneously. When one component is considered to be "placed" within another, that configuration may be directly placed within the other component, or an intermediary component may be present simultaneously. Terms such as "top," "bottom," "up," "down," "left," "right," "front," and "back" used herein are for illustrative purposes only. Several embodiments of this application will be described in detail below with reference to the drawings. Where there is no inconsistency, the following embodiments and their features can be combined with each other. According to Figures 1 to 9, the lamp lighting device 100 provided by the embodiment of this application comprises a base 10, a lamp assembly 20, a locking assembly 30, and a locking plate 40. Here, the lamp assembly 20 is removably connected to the base 10, and the lamp assembly 20 includes a base plate 21 and a lampshade 22, the lampshade 22 being removably connected to the base plate 21 along its extending direction. The locking assembly 30 is positioned on one side of the base plate 21 opposite to the lampshade 22. The locking assembly 30 includes a support rod 31 and a torsion spring 32 wound around the support rod 31. The torsion spring 32 has a first elastic arm 321 and a second elastic arm 322, both facing inward. Both distal ends of the first and second elastic arms 321 and 322 have engaging retaining portions 3211 extending toward the base plate 21. The locking plate 40 is positioned on the base 10. A strip-shaped groove 41 is provided in the locking plate 40, positioned to face the torsion spring 32. A first elastic arm 321 protrudes from one end of the strip-shaped groove 41, and a second elastic arm 322 protrudes from the other end of the strip-shaped groove 41. When the lamp assembly 20 is disassembled in the vertical direction F1, the distal ends of the first elastic arm 321 and the second elastic arm 322 move closer to each other so that the engaging retaining portion 3211 moves along the strip-shaped groove 41 and contacts the edge of the locking plate 40. Specifically, the process of attaching and detaching the lamp assembly 20 to the base 10 can be understood as a process in which the opening and closing of the first elastic arm 321 and the second elastic arm 322 cooperate with the strip-shaped groove 41 of the locking plate 40 by the drive of the torsion spring 32. This allows the first elastic arm 321 and the second elastic arm 322 to suspend the lamp assembly 20 and the base 10 along the vertical direction F1 when detached. Furthermore, the first elastic arm 321, the second elastic arm 322, and the torsion spring 32 are integrally structured. The engagement retaining portion 3211 is typically a bent or hook
