Abstract
Description
Field of the invention
[0001] This utility model relates to the technical field of candle lamp structure and in particular to a bottom cover structure for candle lamp. State of the art
[0002] As a common lighting tool, the structural design of candle lamps has a significant impact on product performance and safety. The traditional base cover structure for candle lamps usually adopts a single cover design, which is connected to the candle body by threads. However, this design has some shortcomings. For example, the cover may become loose or even fall off due to accidental contact or collision during use, exposing internal components such as batteries. This not only affects the normal use of the candle lamp but may also pose a safety hazard due to battery detachment. In addition, the sealing performance of a single cover connected by threads is limited after loosening, which cannot effectively prevent external factors such as moisture and dust from corroding internal components.This shortens the lifespan of the candle lamp. The single cover with a tightly threaded connection makes it difficult for users to distinguish which direction the cover can be unscrewed. Object of the invention
[0003] A bottom cover structure for a candle lamp comprises a candle housing, an inner cover, and an outer cover, wherein a connecting portion is provided at a bottom of the candle housing, and wherein an external thread is provided at an outer side of the connecting portion, and wherein an internal thread is provided at an inner side of the inner cover, and wherein an anti-detachment portion is provided at an outer side of the inner cover, and wherein a plurality of first projections are arranged in an annular matrix arrangement at a bottom of the inner cover, and wherein a plurality of second projections are arranged in an annular matrix arrangement at a bottom in the outer cover, and wherein an inclined surface is provided on one side of the second projection, and wherein the inner cover is located inside the outer cover, and an anti-detachment structure is provided between the inner cover and the outer cover,and wherein the inner cover is connectable to the connecting portion by the thread.,
[0004] The anti-detachment structure comprises an anti-detachment ring and an anti-detachment groove, wherein the anti-detachment ring is provided on the outer side of the inner cover, and wherein the anti-detachment groove is provided on the inner side of the outer cover, and wherein the anti-detachment ring protrudes into the anti-detachment groove.
[0005] A first conical surface is provided below the anti-separation ring, a second conical surface is provided below the anti-separation groove, and the first conical surface and the second conical surface are adapted to each other.
[0006] The anti-detachment ring is made of deformable materials. Several anti-slip recesses are provided on the outside of the outer cover.
[0007] Six first protrusions and six second protrusions are provided. The positive effects of this utility model are as follows: The present utility model provides a spark plug housing, an inner cover, and an outer cover, the inner cover being located inside the outer cover, and the inner cover being threadably connected to the connecting portion of the spark plug housing. Under normal circumstances, the bottom of the inner cover is not in contact with the bottom of the outer cover, allowing the outer cover to rotate freely without the inner cover rotating. This prevents the cover from falling off under certain circumstances (such as accidental contact, contact collision, etc.) when using only a single cover, causing the inner battery to fall off and thus affecting use, or reducing the service life of the internal elements due to poor sealing.Therefore, a two-layer protection consisting of the inner cover and the outer cover can better protect and effectively seal the candle housing.
[0008] The utility model specifically discloses a bottom cover structure for a candle lamp. The bottom cover structure comprises a candle housing, an inner cover, and an outer cover. A connecting portion is provided on a bottom of the candle housing, and an external thread is provided on an outer side of the connecting portion. An internal thread is provided on an inner side of the inner cover, and an anti-detachment portion is provided on an outer side of the inner cover. A plurality of first projections are arranged in an annular matrix arrangement on a bottom of the inner cover. A plurality of second projections are arranged in an annular matrix arrangement on a bottom in the outer cover. A slanted surface is provided on one side of the second projection.and wherein the inner cover is located inside the outer cover, and an anti-detachment structure is provided between the inner cover and the outer cover, and wherein the inner cover is connectable to the connecting portion by the thread. In the bottom cover structure for a candle lamp, an inner cover and an outer cover are provided, wherein the inner cover is located inside the outer cover, and the inner cover is connected to the connecting portion of the candle housing by a thread. Under normal circumstances, the bottom of the inner cover is not in contact with the bottom of the outer cover, and so the outer cover can rotate freely, and the inner cover is not rotated with it. This can prevent loosening caused by accidental contact or collision.

[0010] A floor covering structure for candle lamp, as in Fig. 1 to 4, comprises a plug shell, an inner cover, and an outer cover. A connecting portion is provided at a bottom of the plug shell, and an external thread is provided at an outer side of the connecting portion. An internal thread is provided at an inner side of the inner cover, and an anti-separation portion is provided at an outer side of the inner cover. A plurality of first projections are arranged in an annular matrix arrangement at a bottom of the inner cover, and a plurality of second projections are arranged in an annular matrix arrangement at a bottom in the outer cover. A slope is provided at a side of the second projection. The inner cover is located inside the outer cover, and an anti-separation structure is provided between the inner cover and the outer cover. The inner cover may be connected to the connecting portion by the thread.
[0011] As in Fig. As shown in Figures 2 to 3, the anti-detachment structure includes an anti-detachment ring and an anti-detachment groove. The anti-detachment ring is provided on the outer side of the inner cover, and the anti-detachment groove is provided on the inner side of the outer cover. The anti-detachment ring protrudes into the anti-detachment groove, thereby achieving the anti-detachment connection between the inner cover and the outer cover.
[0012] As in Fig. 2 to 3, a first conical surface is provided below the anti-separation ring and a second conical surface is provided below the anti-separation groove, the first conical surface and the second conical surface being matched to each other.
[0013] The provision of the first conical surface facilitates the extension of the inner cover into the outer cover, thereby achieving a guiding and insertion function. By matching the second conical surface to the first conical surface, it can be ensured that when the outer cover is lifted upward, the inner cover is inserted into the bottom of the outer cover.
[0014] The anti-detachment ring is made of deformable materials, preferably rubber materials, to achieve the anti-detachment effect even when subjected to significant external forces. When the anti-detachment ring is subjected to significant external forces, the inner cover can be separated from the outer cover, allowing easy disassembly of the inner cover and outer cover during assembly or subsequent maintenance.
[0015] As in Fig. As shown in Figure 3, several anti-slip recesses are provided on the outside of the outer cover to increase the anti-slip property of the outer cover, making the outer cover easier for users to grip and rotate. Six first protrusions and six second protrusions are provided. Operation: The present utility model provides a spark plug housing, an inner cover, and an outer cover, the inner cover being located inside the outer cover, and the inner cover being connected to the connecting portion of the spark plug housing by a thread. Under normal circumstances, the bottom of the inner cover is not in contact with the bottom of the outer cover, allowing the outer cover to rotate freely without the inner cover rotating. This prevents the cover from falling off under certain circumstances (such as accidental contact, contact collision, etc.) when using only a single cover, causing the inner battery to fall off and thus affecting use, or reducing the service life of the internal elements due to poor sealing. Therefore, a two-layer protection consisting of the inner cover and the outer cover can better protect and effectively seal the candle housing.
[0016] When it is necessary to open the inner cover, the outer cover is simply moved upwards and placed against the inner cover so that the first and second projections are pressed against each other. The outer cover is then rotated. When rotated, it is ensured that the first projection is placed against a side of the second projection facing away from the inclined surface, and the outer cover is then rotated. By designing an inclined surface, the outer cover rotates above the inner cover when the first projection is rotated toward the inclined surface of the second projection. This prevents the inner cover from rotating. This makes it easier for users to distinguish which direction of rotation should be selected to rotate and open the inner cover, as shown in Fig.5 to 6. By providing the anti-detachment ring on the outer side of the inner cover, providing the anti-detachment groove in the outer cover, and using the material of the anti-detachment ring as a deformable material (rubber), the anti-detachment effect and rotation function can be achieved even when significant external force is applied. When the anti-detachment ring is subjected to significant external force, the inner cover can be separated from the outer cover, allowing the inner cover and outer cover to be easily disassembled during assembly or subsequent maintenance.
