Description

Technical Field

[0001] This utility model relates to the field of candle lamp structure technology, and more specifically to a candle lamp bottom cover structure. Background Technology

[0002] As a common lighting tool, the structural design of candle lamps significantly impacts their performance and safety. Traditional candle lamp caps typically employ a single cap design, connected to the candle shell via threads. However, this design has several drawbacks. For example, during use, the cap can easily loosen or detach due to accidental contact or impact, exposing internal components such as the battery. This not only affects the normal operation of the candle lamp but may also pose a safety hazard due to a dislodged battery. Furthermore, the single cap with a threaded connection offers limited sealing performance once loosened, failing to effectively prevent moisture, dust, and other external factors from corroding internal components, thus shortening the candle lamp's lifespan. Additionally, when the cap is tightened, it's difficult for users to determine which direction to turn to open it. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a candle lamp bottom cover structure. This structure consists of an inner cover and an outer cover, with the inner cover located inside the outer cover. The inner cover is threadedly connected to the candle shell via a connecting part. Under normal circumstances, when the bottom of the inner cover does not abut against the bottom of the outer cover, the outer cover can rotate freely without causing the inner cover to rotate. This avoids the loosening caused by accidental contact or collision that occurs with existing single covers, thus improving the overall protective performance.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A candle lamp base cover structure includes a candle shell, an inner cover, and an outer cover. The bottom of the candle shell is provided with a connecting part, and the outer side of the connecting part is provided with an external thread. The inner cover is provided with an internal thread, and the outer side of the inner cover is provided with an anti-detachment part. The bottom of the inner cover has a plurality of first protrusions arranged in a circular array. The bottom of the outer cover has a plurality of second protrusions arranged in a circular array. One side of each second protrusion is provided with a bevel. The inner cover is located inside the outer cover, and an anti-detachment structure is provided between the inner cover and the outer cover. The inner cover can be threadedly connected to the connecting part.

[0006] Furthermore, the anti-detachment structure includes an anti-detachment ring and an anti-detachment groove. The anti-detachment ring is located on the outer side of the inner cover, and the anti-detachment groove is located on the inner side of the outer cover. The anti-detachment ring extends into the anti-detachment groove.

[0007] Furthermore, a first conical surface is provided below the anti-detachment ring, and a second conical surface is provided below the anti-detachment groove, with the first and second conical surfaces engaging.

[0008] Furthermore, the anti-detachment ring is made of a deformable material.

[0009] Furthermore, the outer side of the outer cover is provided with several anti-slip grooves.

[0010] Furthermore, there are six of each of the first and second bumps.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model provides a candle shell, an inner cover, and an outer cover, with the inner cover located inside the outer cover and connected to the candle shell by a threaded connection. Under normal circumstances, when the bottom of the inner cover does not abut against the bottom of the outer cover, the outer cover can rotate freely without causing the inner cover to rotate. This avoids the problem of the existing single cover falling off under certain circumstances (such as accidental touch, contact, or collision), which could cause the internal battery to fall off and affect the use of the product or reduce the lifespan of internal components due to poor sealing. Thus, the double protection of the inner and outer covers provides good protection and effective sealing for the candle shell.

[0013] When the inner cover needs to be opened, simply press the outer cover upwards against the inner cover so that the first and second protrusions abut against each other, and then rotate the outer cover. When rotating, the first and second protrusions should be in contact with each other on the side away from the inclined surface. By setting the inclined surface, when the first protrusion rotates through the inclined surface of the second protrusion, it will pass over the second protrusion and will not drive the inner cover to rotate. This makes it easier for users to distinguish which direction of rotation will drive the inner cover to rotate and open.

[0014] Furthermore, by setting an anti-detachment ring on the outside of the inner cover and an anti-detachment groove on the inside of the outer cover, and by setting the anti-detachment ring to a deformable material (rubber), the anti-detachment effect and rotation function can be achieved without being subjected to a large external force, while the inner cover and outer cover can be separated under a large external force, making it easy to disassemble and assemble the inner cover and outer cover during installation or later maintenance.

[0025] A candle lamp base cover structure, such as Figure 1-4As shown, the candle includes a candle shell 1, an inner cover 3, and an outer cover 4. The bottom of the candle shell 1 is provided with a connecting part 2, and the outer side of the connecting part 2 is provided with an external thread. The inner side of the inner cover 3 is provided with an internal thread, and the outer side of the inner cover 3 is provided with an anti-detachment part. The bottom of the inner cover 3 has a plurality of first protrusions 303 arranged in a ring. The bottom of the outer cover 4 has a plurality of second protrusions 403 arranged in a ring. One side of the second protrusions 403 is provided with a slope 405. The inner cover 3 is located inside the outer cover 4, and an anti-detachment structure is provided between the inner cover 3 and the outer cover 4. The inner cover 3 can be threadedly connected to the connecting part 2.

[0026] Preferred, such as Figure 2-3 As shown, the anti-detachment structure includes an anti-detachment ring 301 and an anti-detachment groove 401. The anti-detachment ring 301 is disposed on the outer side of the inner cover 3, and the anti-detachment groove 401 is disposed on the inner side of the outer cover 4. The anti-detachment ring 301 extends into the anti-detachment groove 401, thereby realizing the anti-detachment connection between the inner cover 3 and the outer cover 4.

[0027] Preferred, such as Figure 2-3 As shown, a first conical surface 302 is provided below the anti-detachment ring 301, and a second conical surface 402 is provided below the anti-detachment groove 401. The first conical surface 302 and the second conical surface 402 cooperate with each other.

[0028] Specifically, by setting the first conical surface 302, the inner cover 3 can be easily inserted into the outer cover 4, which can play a guiding role in the insertion; while the second conical surface 402 is set to cooperate with the first conical surface 302, and at the same time, when the outer cover 4 is pushed up, it can ensure that the inner cover 3 is inserted into the bottom of the outer cover 4.

[0029] Preferably, the anti-detachment ring 301 is made of a deformable material, preferably rubber, so that it can achieve the anti-detachment effect without being subjected to a large external force, and can detach the inner cover 3 and the outer cover 4 under a large external force, so that the inner cover 3 and the outer cover 4 can be easily disassembled during installation or later maintenance.

[0030] Preferred, such as Figure 3 As shown, the outer cover 4 has several anti-slip grooves 404 on its outer side, thereby increasing the anti-slip performance of the outer cover 4 and making it easier for users to pinch and rotate it.

[0031] Preferably, there are six of each of the first protrusion 303 and the second protrusion 403.

[0032] Working principle:

[0033] This utility model provides a candle housing 1, an inner cover 3, and an outer cover 4. The inner cover 3 is located inside the outer cover 4 and is threadedly connected to the candle housing 1 via a connecting part 2. Under normal circumstances, when the bottom of the inner cover 3 does not abut against the bottom of the outer cover 4, the outer cover 4 can rotate freely without causing the inner cover 3 to rotate. This avoids the situation where a single cover is used and, under certain circumstances (such as accidental contact or collision), the cover falls off, causing the internal battery to fall out and affecting the use, or the internal components to be unable to achieve a good seal and thus reducing their service life. Therefore, with the double protection of the inner cover 3 and the outer cover 4, the candle housing 1 can be well protected and effectively sealed.

[0034] When it is necessary to open the inner cover 3, simply place the outer cover 4 upwards against the inner cover 3, so that the first protrusion 303 and the second protrusion 403 abut against each other, and then rotate the outer cover 4. During rotation, the side of the first protrusion 303 and the second protrusion 403 away from the side with the inclined surface 405 must be in contact and abut against each other. Because of the inclined surface 405, when the first protrusion 303 rotates along the inclined surface of the second protrusion 403, it will pass over the second protrusion 403 and will not cause the inner cover 3 to rotate. This makes it easier for the user to distinguish which direction of rotation will cause the inner cover 3 to rotate and open. Figure 5-6 As shown;

[0035] Furthermore, by setting an anti-detachment ring 301 on the outside of the inner cover 3 and an anti-detachment groove 401 in the inside of the outer cover 4, and by setting the material of the anti-detachment ring 301 to a deformable material (rubber), the anti-detachment effect and rotation function can be achieved without being subjected to a large external force, while the inner cover 3 and the outer cover 4 can be separated under a large external force, so that the inner cover 3 and the outer cover 4 can be easily disassembled during installation or later maintenance.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
