Description

Technical Field

[0001] The utility model relates to an emergency light source, also known as an emergency bulb, which has a built-in battery that can be flexibly removed. Background Art

[0002] The emergency bulb belongs to a lighting source, which is internally equipped with an independent power source to play an emergency lighting role during a power outage and can also be used independently as a lighting unit. Currently, there are various styles of emergency bulbs, and the corresponding structures for replacing the battery are also diverse. For example, the lampshade and the lamp cup are screwed open from each other. After using this method many times, the lamp cup and the lampshade are likely to become loose due to increased gaps, thus affecting the use of the bulb. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an emergency bulb with replaceable battery, and the technical problem to be solved is: optimizing the structure of the emergency bulb to facilitate battery replacement and avoid gaps between the lampshade and the lamp cup.

[0005] The interior of the lamp cup has a hollow inner circular plate, and the hollow position of the inner circular plate limits and fixes the battery.

[0006] The buckle and the second shaft connection part protrude from the lamp cover as a whole and extend towards the lamp cup.

[0007] There are two ring protrusions, and there is a limiting plate between the two ring protrusions. The lampshade has a limiting groove at the corresponding position, and the limiting plate and the limiting groove cooperate with each other.

[0008] The beneficial effect of the utility model is: by designing a hinged structure and a buckle structure, one end between the lamp cup and the lamp cover is connected by hinge, and the other end is separated by buckle, thus avoiding the need to use the traditional separation method, preventing the gap between the lamp cup and the lampshade from expanding, and being convenient for separation with easy operation; by adding the lamp cover structure, the connection between the lamp cup and the lampshade is realized through the lamp cover for transition.

[0024] Please refer to Figures 1 to 9 In, a battery - replaceable emergency light bulb in the figure mainly optimizes the design of components such as the lamp cup 1, the lamp cover 2, and the lampshade 3. This emergency light bulb also has existing components such as a driver and LED lamp beads. The core innovation point of this case is that the way of keeping one - end connection between the lamp cup 1 and the lamp cover 2 replaces the existing completely - detached way, thus simplifying the operation of removing the battery 5.

[0025] The lamp cup 1 in the figure adopts the conventional design of the lamp cup 1 as a whole. It has a lamp cap 11 at the top, and the middle and lower parts form a hollow horn structure. At the edge of the outermost end of the horn, that is, at the position of the cup mouth 12, the first shaft connection part 13 and the buckle groove 14 are symmetrically designed; among them, the first shaft connection part 13 is designed with two longitudinally arranged plates 131 with intervals. At the outer end of each longitudinally arranged plate 131 facing outward, a C-shaped cavity 1311 for clamping is designed. The cavity 1311 has an opening for the insertion of the second shaft connection part 21; the buckle groove 14 is a straight groove structure, which facilitates the direct clamping of the buckle 22 of the lamp cover 2 into the buckle groove 14. At the position beside the above-mentioned first shaft connection part 13 and buckle groove 14, a mounting post 15 structure is also designed, which facilitates the fixing of the inner circular plate 4 in the lamp cup 1 by screws. In order to facilitate the limit fixation of the battery 5, a structure of the above-mentioned inner circular plate 4 can be installed inside the lamp cup 1. The inner part of the inner circular plate 4 is hollow to facilitate the penetration and limit of the battery 5. In practical applications, the above-mentioned lamp cup 1 can be further optimized in design.

[0026] The lamp cover 2 in the figure is located between the lamp cup 1 and the lamp shade 3 and is used to connect and fix the above two components. The lamp cover 2 as a whole adopts a circular body structure design. At the edge of the end facing the lamp cup 1, the second shaft connection part 21 and the buckle 22 are symmetrically designed. These two components protrude and extend towards the lamp cup 1 as a whole and are respectively aligned with the positions of the first shaft connection part 13 and the buckle groove 14. The above-mentioned second shaft connection part 21 is a straight rod-shaped structure as a whole, and the buckle 22 is a conventional buckle 22 structure. Through the above configuration, when one end of the lamp cup 1 and the lamp cover 2 is in a separated state, the first shaft connection part 13 and the second shaft connection part 21 maintain a shaft connection relationship, and the buckle 22 and the buckle groove 14 maintain a separated state. The above-mentioned lamp cover 2 is designed with a porous structure inside, which facilitates heat dissipation and the penetration and installation of other components. The above-mentioned lamp cover 2 is designed with a symmetrically arranged annular ring protrusion 23 structure in the direction facing the lamp shade 3, which facilitates the rotational assembly with the lamp shade 3. At the same time, in order to facilitate the fixation of the lamp shade 3, a longitudinal limiting plate 24 structure can be designed between the two ring protrusions 23. In practical applications, the above-mentioned lamp cover 2 can be further optimized in design.

[0027] The main structure of the lamp shade 3 in the figure is the same as the existing one. In order to facilitate the assembly with the lamp cover 2, an annular ring groove 31 is designed at the position aligned with the ring protrusion 23 and maintains a concave-convex assembly. At the same time, in order to limit the position, a limiting groove 32 structure is designed at the position aligned with the limiting plate 24 to maintain a limiting cooperation relationship. In practical applications, the above-mentioned lamp shade 3 can be further optimized in design.
