Description

Technical Field

[0001] The utility model belongs to the technical field of anti-seepage of lamp beads, and particularly relates to an LED lamp bead with an anti-seepage structure. Background Art

[0002] LED lamp bead is the English abbreviation of light-emitting diode, simply called LED, which is a common name. LED lamp beads use low-voltage power supply, so the power supply driving it is a safer power supply than high-voltage power supply, and it is especially suitable for public places. LED lamp beads are very small and can be prepared into devices of various shapes, suitable for variable environments. When the existing LED lamp beads are used outdoors, they are prone to water seepage in rainy days, which causes the LED lamp beads to be damaged, limits the use places of the LED lamp beads, shortens the service life of the LED lamp beads, and brings inconvenience to the users of the LED lamp beads.

[0003] In response to the challenge of the shortened service life of LED lamp beads caused by water seepage problems, LED lamp bead solutions with anti-seepage structures have been introduced on the market. For example, an LED lamp bead described in the Chinese utility model patent document with the publication number CN216079363U realizes sealing through a threaded connection and has the convenience of quick disassembly. However, this method has obvious deficiencies. In order to ensure the smooth meshing of the threads, its design will inevitably leave more or less gaps between the threads. Worse still, with frequent disassembly and installation operations, these gaps will gradually expand, resulting in a sharp decline in waterproof performance. More critically, once disturbed by external vibration, the threaded connection may become loose, seriously affecting its overall connection stability and waterproofness.

[0004] Therefore, it is very necessary to invent an LED lamp bead with an anti-seepage structure. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides an LED lamp bead with an anti-seepage structure, including a lamp bead base, a lamp bead and its anti-seepage structure, a clamping wheel, a clamping groove and a guiding chute. The lamp bead base is internally installed with the lamp bead and its anti-seepage structure in a transition fit manner, and they are clamped together through the clamping wheel; the clamping wheel is arranged in the clamping groove opened on the lamp bead base and the lamp bead and its anti-seepage structure, and is slidably installed in the clamping groove through the guiding chute;

[0006] The lamp bead and its anti-seepage structure include a buffer sleeve, a threaded groove, a gasket, a lamp bead, a thread, a sealing ring, a sealing platform and a clamping groove. The buffer sleeve is installed in the lamp bead base by transition fit. The threaded groove is arranged inside the buffer sleeve, and the gasket is embedded therein. The buffer sleeve is connected to the lamp bead by meshing through the threaded groove and the thread provided on the lamp bead. A sealing ring is embedded on the bottom surface of the lamp bead, a sealing platform is fixedly installed on the lamp bead, and a clamping groove is arranged on the sealing platform, which is flush with the clamping groove; the clamping groove and the guiding chute are arranged on the buffer sleeve.

[0007] Preferably, the clamping groove and the clamping slot provided on the lamp bead base and the buffer sleeve form a guiding groove, and the guiding groove is an inclined groove body; the wall thickness of the buffer sleeve is smaller than the diameter of the clamping wheel.

[0008] Preferably, the guiding chute provided on the inner surface of the clamping groove allows the clamping wheel to roll and displace inside it, and the upper half of the clamping wheel protrudes outside.

[0009] Preferably, the sealing ring provided on the bottom surface of the lamp bead is in close contact with the bottom surface of the buffer sleeve, and the lamp bead and the buffer sleeve are installed together through the gasket and the thread.

[0010] Preferably, the thread is located below the sealing platform. The sealing platform is a circular conical platform structure, and the inclined surface of the sealing platform is in interference contact with the sealing platform provided inside the buffer sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] On the basis of the original scheme, the utility model is innovated, and a clever sealing structure including a gasket, a sealing ring and a sealing platform is added. This design enables, after the thread is screwed in, an interference contact to be formed through pressure, thereby directly blocking the outside rainwater and effectively avoiding the possibility of rainwater seeping between the threads. Further, the setting of the sealing ring effectively prevents the rainwater that has seeped into the thread gap from further eroding the lamp bead structure, achieving a double-layer sealing effect and greatly improving the waterproof performance.

[0013] In addition, the utility model also cleverly designs the clamping wheel and the clamping groove structure. The combination of the two can firmly lock the lamp bead base, the lamp bead and its anti-seepage structure together. This design effectively prevents the problem of thread loosening caused by external vibration, and further improves the overall connection stability and waterproof performance.

[0021] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0022] An LED lamp bead with a water leakage prevention structure provided by the utility model comprises a lamp bead base 1, a lamp bead and its water leakage prevention structure 2, a clamping wheel 3, a clamping groove 4 and a guiding chute 5. The lamp bead and its water leakage prevention structure 2 are installed in the lamp bead base 1 with transitional fit and are clamped together through the clamping wheel 3. The clamping wheel 3 is arranged in the clamping groove 4 opened on the lamp bead base 1 and the lamp bead and its water leakage prevention structure 2 and is slidably installed in the clamping groove 4 through the guiding chute 5.

[0023] The lamp bead and its water leakage prevention structure 2 comprise a buffer sleeve 21, a threaded groove 22, a sealing gasket 23, a lamp bead 24, a thread 25, a sealing ring 26, a sealing platform 27 and a clamping groove 28. The buffer sleeve 21 is installed in the lamp bead base 1 with transitional fit. The threaded groove 22 is opened inside the buffer sleeve 21 and the sealing gasket 23 is embedded therein. The buffer sleeve 21 is meshed and connected with the lamp bead 24 through the threaded groove 22 and the thread 25 provided on the lamp bead 24. The sealing ring 26 is embedded on the bottom surface of the lamp bead 24. The sealing platform 27 is fixedly installed on the lamp bead 24. The clamping groove 28 is opened on the sealing platform 27 and is flush with the clamping groove 4. The clamping groove 4 and the guiding chute 5 are opened on the buffer sleeve 21, and the lamp bead and its water leakage prevention structure 2 achieve an efficient sealing effect. Embodiment 1:

[0024] Specifically, the clamping groove 4 and the clamping groove 28 opened on the lamp bead base 1 and the buffer sleeve 21 form a guiding groove, which is an inclined groove body to ensure that the clamping wheel 3 can accurately and quickly enter the clamping position (the clamping groove 28). The wall thickness of the buffer sleeve 21 is smaller than the diameter of the clamping wheel 3, which enables the clamping wheel 3 to closely fit in the clamping groove 4 after being clamped, forming a stable connection structure, which is used to limit the rotation of the buffer sleeve 21 and the sealing platform 27.

[0025] Specifically, the guiding chute 5 provided on the inner surface of the clamping groove 4 allows the clamping wheel 3 to roll and displace inside it. This design enables the clamping wheel 3 to smoothly slide along the guiding chute during the clamping process until it reaches the predetermined position, thereby ensuring the accuracy and stability of the clamping. And the upper half of the clamping wheel 3 protrudes outside.

[0026] Specifically, the sealing ring 26 provided on the bottom surface of the lamp bead 24 is in close contact with the bottom surface of the buffer sleeve 21. The lamp bead 24 and the buffer sleeve 21 are installed together through the sealing gasket 23 and the thread 25. The design of close contact can effectively prevent moisture from seeping in through the gap between the lamp bead 24 and the buffer sleeve 21, thus achieving the first layer of waterproof protection. In addition, the lamp bead 24 and the buffer sleeve 21 are also installed through the engagement of the sealing gasket 23 and the thread 25. The setting of the sealing gasket 23 further enhances the waterproof performance. It can fill the tiny gaps between the threads and prevent moisture from seeping into the interior through the threads. The engagement of the threads provides a firm connection, ensuring the stable combination between the lamp bead 24 and the buffer sleeve 21.

[0027] Specifically, the thread 25 is located below the sealing table 27. The sealing table 27 adopts a circular frustum structure, and its inclined surface forms an interference contact with the corresponding part (sealing gasket 23) inside the buffer sleeve 21. The design principle of this interference contact is that when two components come into contact with each other, due to a certain dimensional difference, a certain pressure is generated between them, thus forming a tight fit. This fit can not only effectively prevent the infiltration of moisture, but also resist external vibration and impact to a certain extent, ensuring the stability of the connection.

[0028] Working principle:

[0029] First of all, during the installation process, the lamp bead and its anti-seepage structure 2 are installed into the interior of the lamp bead base 1 with a transition fit. At this time, the thread groove 22 inside the buffer sleeve 21 meshes with the thread 25 on the lamp bead 24, and through a rotational movement, a tight connection between the two is achieved. During this process, the sealing gasket 23 is placed between the two, playing a role in filling the thread gaps and enhancing the waterproof performance. At the same time, the sealing ring 26 at the bottom of the lamp bead 24 is in close contact with the bottom surface of the buffer sleeve 21, forming an additional waterproof barrier. This double-sealing structure ensures that moisture is difficult to seep in through the gap between the lamp bead and the buffer sleeve. Next, the clamping wheel 3 is placed in the clamping groove 4 opened on the lamp bead base 1 and the buffer sleeve 21. Due to the special design of the clamping groove 4 and the guiding chute 5, the clamping wheel 3 can slide smoothly along the guiding chute 5 until the clamping wheel 3 reaches the predetermined position. At this time, the clamping wheel 3 not only plays a role in fixing the lamp bead and its anti-seepage structure 2, but also can effectively prevent it from loosening or rotating. During the clamping process, the circular frustum structure of the sealing table 27 plays a key role. Its inclined surface forms an interference contact with the sealing gasket 23 inside the buffer sleeve 21. This contact method not only increases the contact area, but also achieves a tight fit through the generated pressure. This interference contact not only further enhances the waterproof performance, but also can effectively resist external vibration and impact, ensuring the stability of the connection.

[0030] Any technical solution using the technical solution of the present utility model, or any technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
