Description

Technical Field

[0001] This invention relates to the field of LED bulb technology, specifically to an LED bulb with a quick-release lamp holder and body. Background Technology

[0002] In the current production, assembly, and daily disassembly and use of LED bulbs, the industry commonly uses either threaded connections or conventional elastic snap-fit ​​structures to combine the bulb base and body. Both of these assembly structures have significant drawbacks in practical applications. Threaded connections are not only cumbersome to install and remove, but frequent tightening can also lead to stripping and loosening of the threads. Traditional elastic snap-fit ​​structures require operators to spend considerable time repeatedly adjusting the relative positions of the elastic telescopic posts and corresponding snap-fit ​​ports to achieve proper alignment. This results in low overall assembly efficiency, significant alignment difficulties, and greatly impacts the convenience of LED bulb assembly. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide an LED bulb with a quick-release lamp head and lamp body, so as to solve the problem of difficult alignment when the lamp head and lamp body are connected and engaged as mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an LED bulb with a quick-release lamp head and lamp body, comprising a connecting tube fixed to the bottom of the lamp head structure, and a lamp body assembled with the lamp head structure via the connecting tube. The inner wall of the connecting tube is provided with a plurality of slots extending outward, and the inner wall of the connecting tube is provided with a plurality of sliding grooves spaced apart from the slots. Each sliding groove is vertically slidably installed with a guide plate, and the lower part of the guide plate is tapered from top to bottom. When the guide plate is in contact with the bottom wall of the sliding groove, the lower end extends below the connecting tube. The main body of the lamp includes a plug-in post that matches the inner diameter of the connecting pipe and a round bulb fixed to the bottom of the plug-in post. The surface of the plug-in post has fitting grooves that are consistent with the number, width and curvature of the guide plate. The plug-in post has outwardly extending spring posts inside. When the plug-in post is aligned and fitted with the guide plate through the fitting groove, the spring posts and the groove opening are on the same vertical line.

[0005] Preferably, the bottom of the connecting pipe is integrally formed with a conical ring whose diameter gradually increases from top to bottom, and when the spring post is in a naturally relaxed state, the distance between its outer end and the central axis of the plug post is less than the inner radius of the bottom of the conical ring.

[0006] Preferably, a sealing ring is fixedly fitted on the surface of the plug post, and the sealing ring tapers from the middle to the top. When the plug post is combined with the connecting pipe, the middle to the top of the sealing ring fits seamlessly with the inner wall of the conical ring.

[0007] Preferably, an arc-shaped step surface is formed between the top surface of the sealing ring and the fitting groove, and the radial width of the arc-shaped step surface is consistent with the radial thickness of the guide plate.

[0008] Preferably, when the spring post extends into the slot without being compressed, its outer end is between the middle and the outer side of the slot, and one corner of the outer end of the spring post is chamfered to form a guide slope, and the distance between the inner walls on both sides of the slot is greater than the width of the spring post.

[0009] Preferably, the surface of the connecting tube is slidably fitted with a dial ring structure, and the top of the dial ring structure is provided with a slider that is the same number as the number of spring pillars. Each slider is slidably installed with a pressing block on the side near the central axis of the connecting tube. The pressing block is located inside the groove, and the thickness of the pressing block gradually decreases from the side away from the spring pillar in the same groove to the other side.

[0010] Preferably, the surface of the connecting pipe is equipped with reinforcing ribs, which correspond one-to-one with the grooves opened on the inner wall of the connecting pipe, and the two are arranged facing each other inside and out.

[0011] Preferably, the bottom of the dial ring structure has an insertion interface, and the top of the reinforcing rib is fixed with a limiting strip that fits into the insertion interface. The height of the limiting strip is less than the sliding stroke of the dial ring structure relative to the slider. When the dial ring structure is in contact with the top surface of the reinforcing rib, the limiting strip is embedded in the insertion interface.

[0012] By employing the above technical solution, the present invention provides an LED bulb with a quick-release lamp holder and lamp body, which has at least the following beneficial effects: 1. This invention uses the exposed guide plate at the bottom of the connector as a visual positioning reference to align the fitting grooves on the outer wall of the plug-in post with the exposed guide plate. Then, the spring post is squeezed and the plug-in post is pushed upwards smoothly. With the cooperation of the spring post and the groove, the overall structure can be locked and fixed. This completely eliminates the tedious operation of repeatedly checking the position of the spring post and the groove in the traditional assembly method, effectively simplifies the assembly process, and can greatly improve the overall assembly efficiency and ease of use of LED bulbs.

[0013] 2. The present invention guides the spring column to retract inward on its own by means of the inclined inner wall of the conical ring, so that the spring column can be inserted into the connector without pressing it again. This makes the assembly of the lamp body and the connector smoother and more convenient.

[0014] 3. The present invention forms an arc-shaped stepped surface between the top surface of the sealing ring and the fitting groove. Following the upward trend of the plug-in post, the guide plate can be lifted upward along the sliding groove. Without the need for manual manipulation or additional driving structure, the vertical reset action of the guide plate can be completed in the synchronous action of assembly and plugging, thus ensuring the overall structural layout is neat.

[0015] 4. In this invention, by rotating the dial ring structure, the slider can drive several extrusion blocks to rotate in the direction of the spring column in the same slot. The several extrusion blocks simultaneously extrude the spring column in their respective slots inward, directly generating a downward pulling force on the round bulb, thereby realizing the separation between the lamp body and the connecting pipe.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] Example 1 Please see Figures 1-6The present invention describes an LED bulb with quick-release lamp head and lamp body. The LED bulb is composed of two main parts: lamp head structure 1 and lamp body 3. A connecting pipe 2 is fixedly installed at the bottom of the lamp head structure 1. The lamp body 3 mainly relies on the connecting pipe 2 to realize the combination and assembly between the lamp head structure 1 and the lamp body 3.

[0020] To provide guidance and positioning when the lamp body 3 is assembled with the connecting pipe 2, this embodiment features a through-groove on the wall of the connecting pipe 2, forming multiple slots 201. Simultaneously, multiple sliding grooves 202 are formed on the inner wall of the connecting pipe 2. All sliding grooves 202 and slots 201 are spaced apart and do not interfere with each other. Each sliding groove 202 has a vertically sliding guide plate 203 installed within it. Under external force, the guide plate 203 can smoothly slide vertically along the interior space of the sliding groove 202. The lower part of the guide plate 203 is designed with a tapering structure that gradually narrows from top to bottom. When the guide plate 203 naturally hangs down to fully fit and limit its position against the bottom of the sliding groove 202, its lower end will extend below the connecting pipe 2. The exposed guide plate 203 provides precise guidance during subsequent insertion and assembly, offering a clear positioning benchmark for the alignment and insertion of the lamp body 3.

[0021] As described above, the main body 3 of the lamp includes a plug-in post 301 and a circular bulb 302 fixed to the bottom of the plug-in post 301. The outer diameter of the plug-in post 301 matches the inner diameter of the connecting pipe 2, ensuring that the plug-in post 301 smoothly extends into the connecting pipe 2 to complete the assembly. Multiple fitting grooves 303 are formed on the surface of the plug-in post 301. The number, width, and overall curvature of the fitting grooves 303 are consistent with the guide plate 203 on the inner side of the connecting pipe 2, so as to form a tight fit with the upper part of the guide plate 203. The plug-in post 301 has an outwardly extending spring post 304 inside. During the process of the plug-in post 301 accurately aligning and fitting with the guide plate 203 using the fitting grooves 303, the spring post 304 inside the plug-in post 301 can naturally be aligned with the groove 201 on the inner wall of the connecting pipe 2. Automatic alignment can be achieved through the structural layout without manual adjustment or calibration.

[0022] It is worth mentioning that when actually assembling the lamp head structure 1 and the lamp body 3, the operator only needs to place the lamp body 3 directly below the connecting pipe 2, and use the exposed guide plate 203 at the bottom of the connecting pipe 2 as a visual positioning reference. Align the fitting grooves 303 on the outer wall of the plug-in post 301 with the exposed guide plate 203 one by one, then squeeze the spring post 304 and push the plug-in post 301 upwards smoothly, so that the plug-in post 301 gradually extends into the connecting pipe 2 until the plug-in post 301 and the connecting pipe 2 are completely fitted and connected.

[0023] In this assembly process, the spring post 304 is compressed by the inner wall of the connector 2, and is in a contracted state. After the insertion post 301 and the connector 2 are assembled in place, the spring post 304 is exactly aligned with the slot 201 on the connector 2. At this time, the compressive force on the spring post 304 is released, and it naturally extends outward into the slot 201. The overall structure is locked and fixed by the cooperation between the spring post 304 and the slot 201. The entire assembly process is simple and smooth, completely eliminating the tedious operation of repeatedly checking the position of the spring post 304 and the slot 201 required by traditional assembly methods. This effectively simplifies the assembly process and can greatly improve the overall assembly efficiency and ease of use of LED bulbs.

[0024] Example 2 Following the above embodiment, the bottom of the connecting tube 2 is integrally formed with a conical ring 204 whose diameter gradually increases from top to bottom. When the spring post 304 is in a naturally relaxed state, the distance between its outer end and the central axis of the insertion post 301 is less than the inner radius of the bottom of the conical ring 204. Therefore, in the initial stage of inserting the insertion post 301 into the connecting tube 2, there is no need to press the spring post 304. It can be directly aligned and then the insertion post 301 can be directly inserted upwards. During this process, the spring post 304 can retract inwards autonomously under the guidance of the inclined inner wall of the conical ring 204.

[0025] Example 3 like Figures 1-3 As shown, a sealing ring 305 is fixedly sleeved on the surface of the plug post 301. The sealing ring 305 is tapered from the middle to the top. When the plug post 301 is combined with the connecting pipe 2, the middle to the top of the sealing ring 305 fits seamlessly with the inner wall of the conical ring 204. The conical surface fit can form a circumferential uniform fitting constraint force, making the docking position between the plug post 301 and the connecting pipe 2 more stable, while improving the aesthetics.

[0026] An arc-shaped step surface is formed between the top surface of the sealing ring 305 and the fitting groove 303. The radial width of this arc-shaped step surface is consistent with the radial thickness of the guide plate 203. During the process of the plug-in post 301 gradually extending into the connector 2 from bottom to top to complete the fitting assembly, as the plug-in post 301 moves upward, the corresponding arc-shaped step surface will gradually abut against the bottom end of the guide plate 203, which is exposed below. Relying on the precisely matched thickness, a stable force support is formed, and the guide plate 203 is lifted upward along the slide groove 202 along the upward trend of the plug-in post 301. It can complete the vertical reset action of the guide plate 203 in the synchronous action of the assembly and plugging without the need for manual manipulation or additional driving structure. This allows the guide plate 203 to be smoothly stored in the slide groove 202, which will not obstruct or interfere with the upward assembly stroke of the plug-in post 301, and will also allow the guide plate 203 to return to the preset installation position after assembly, ensuring the overall structural layout is neat.

[0027] Example 4 In the above embodiment one, multiple spring posts 304 are provided. When the insertion post 301 is separated from the connecting pipe 2, it is inconvenient to press several spring posts 304 at the same time. In order to effectively solve this problem, as follows: Figure 2 , Figure 5 and Figure 6 As shown, when the spring post 304 extends into the slot 201 without being compressed, its outer end is between the middle and the outer side of the slot 201, and one corner of the outer end of the spring post 304 is chamfered to form a guide slope. The distance between the inner walls on both sides of the slot 201 is greater than the width of the spring post 304.

[0028] Following the above, a toggle structure 4 is slidably fitted onto the surface of the connecting pipe 2. The top of the toggle structure 4 has sliders 401, the same number as the spring pillars 304. Each slider 401 has a pressing block 402 slidably mounted on the side closest to the central axis of the connecting pipe 2. The pressing blocks 402 are located inside the slot 201, and their thickness gradually decreases from the side furthest from the spring pillars 304 in the same slot 201 to the other side. In practical application, by rotating the toggle structure 4, the sliders 401 drive several pressing blocks 402 to rotate towards the direction of the spring pillars 304 in the same slot 201. This causes the pressing blocks 402 with gradually changing thickness to simultaneously exert a pressing force on the spring pillars 304 towards the central axis of the connecting pillar 301. This causes the spring pillars 304 to contract inwards simultaneously, and then directly exert a downward pulling force on the circular bulb 302, thus achieving the separation of the lamp body 3 from the connecting pipe 2.

[0029] Example 5 The surface of the connecting pipe 2 is equipped with reinforcing ribs 205, which correspond one-to-one with the sliding grooves 202 opened on the inner wall of the connecting pipe 2, and the two are arranged facing each other inside and out, in order to enhance the structural strength of the connecting pipe 2 where the sliding grooves 202 are opened.

[0030] To prevent the dial mechanism 4 from rotating unnecessarily, such as Figure 5 and Figure 6 As shown, in this embodiment, an insertion interface 403 is provided at the bottom of the dial ring structure 4, and a limiting strip 206 that fits into the insertion interface 403 is fixed at the top of the reinforcing rib 205. The height of the limiting strip 206 is less than the sliding stroke of the dial ring structure 4 relative to the slider 401. When the dial ring structure 4 is in contact with the top surface of the reinforcing rib 205, the limiting strip 206 is embedded in the insertion interface 403, thereby preventing the dial ring structure 4 from rotating in case of accidental contact. When it is necessary to disassemble the lamp body 3 and the connecting pipe 2, the dial ring structure 4 is lifted upward to cause the insertion interface 403 to disengage from the limiting strip 206. At the same time, the slider 401 slides upward along the guide groove on the surface of the extrusion block 402, but does not disengage.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
