Description

Technical Field

[0001] This utility model relates to the field of LED indicator bulbs, and more particularly to an LED indicator bulb that is easy to disassemble. Background Technology

[0002] LED indicator bulbs are widely used in industrial control equipment, home appliances, instruments, and other fields to display the real-time operating status of equipment (such as power on / off, fault warnings, mode switching, etc.). In practical use, indicator bulbs may experience LED chip failure or circuit malfunction due to prolonged operation, requiring frequent disassembly and replacement. Furthermore, quick bulb removal is necessary during equipment maintenance to troubleshoot wiring problems. Therefore, the "ease of disassembly and assembly" and "connection stability" of indicator bulbs are of high importance.

[0003] Currently, most LED indicator bulbs on the market use threaded connections or simple snap-fit ​​connections. Threaded connections rely on a screw fit for fixation, but the threads are prone to wear due to frequent disassembly and assembly, or corrosion due to environmental dust and moisture, resulting in increased disassembly resistance or even jamming. Snap-fit ​​connections are easy to operate, but the snap-fit ​​structure is usually not strong enough and is prone to breakage after long-term use, causing the bulb to loosen and fall off, affecting the reliability of equipment status indication.

[0004] Therefore, to address the aforementioned problems, an easily detachable LED indicator bulb is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easily detachable LED indicator bulb, aiming to improve the reliability problems of existing LED indicator bulbs, such as easy wear, corrosion, breakage, and loosening.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An easily detachable LED indicator bulb includes an LED bulb, a mounting base, a locking mechanism, and a drive mechanism;

[0008] The top of the mounting base is detachably connected to an LED bulb, and a plug-in post is fixedly installed on the top of the mounting base. A snap-fit ​​ring is fitted on the bottom outer side of the LED bulb. The top of the mounting base has a mounting groove that matches the plug-in post. The locking mechanism includes four L-shaped locking rods distributed in a square. The horizontal end of the L-shaped locking rod is snapped with an arc-shaped rod. Its vertical section passes through the mounting base and is fixedly connected to a limit plate on the outside. A compression spring is fitted on the outside of the vertical section of the L-shaped locking rod. The two ends of the compression spring abut against the limit plate and the inner wall of the mounting base, respectively.

[0009] As a further description of the above technical solution:

[0010] The driving mechanism includes a rotating ring, which is rotatably sleeved on the outside of the mounting base. An extension plate is fixed to its outer peripheral wall, and a slot adapted to the vertical end of the L-shaped locking rod is opened at the top. The outer side of the L-shaped locking rod is slidably embedded in the slot.

[0011] As a further description of the above technical solution:

[0012] The fastening ring has an annular protrusion structure, and the horizontal end of the L-shaped locking rod has a hook-shaped structure that is adapted to the fastening ring.

[0013] As a further description of the above technical solution:

[0014] The mounting base has a concave stop groove on its outside, and a return spring is fixedly connected to the bottom of the mounting base. The end of the return spring away from the bottom of the mounting base abuts against the rotating ring.

[0015] As a further description of the above technical solution:

[0016] The outer side of the extension plate slides inside the concave stop groove, and the shapes of the two ends of the concave stop groove are adapted to the shape of the extension plate.

[0017] As a further description of the above technical solution:

[0018] The limiting plate is a square plate, and the mounting base has a movable cavity inside, in which the limiting plate slides vertically.

[0019] As a further description of the above technical solution:

[0020] The compression spring always applies an elastic thrust to the L-shaped locking rod towards the bottom of the mounting base;

[0021] As a further description of the above technical solution:

[0022] The horizontal section of the L-shaped locking rod is deformable.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the hook-shaped structure of the snap ring and the L-shaped locking rod cooperates. During installation, the snap ring squeezes the L-shaped locking rod to shrink and deform. Pressing down the extension plate drives the rotating ring to move down, and the compression spring resets and pushes the L-shaped locking rod into the snap ring. During disassembly, rotating the extension plate causes the slot to misalign with the L-shaped locking rod, and the reset spring pushes the rotating ring to push out the L-shaped locking rod. This achieves the beneficial effect of quickly disassembling and assembling LED bulbs by hand, without the need for tools, and significantly improves maintenance efficiency.

[0025] 2. In this utility model, a dual locking structure is used, consisting of a vertical limiting ring and a horizontal limiting ring. The hook-shaped structure of the L-shaped locking rod engages with the locking ring to restrict the vertical displacement of the LED bulb. The slot of the rotating ring engages with the vertical section of the L-shaped locking rod to restrict horizontal rotation. The matching design of the concave stop groove and the extension plate ensures a stable locking state. This achieves the beneficial effect of firmly fixing the LED bulb in two dimensions, effectively preventing loosening or falling off and extending its service life. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 4 One embodiment of this utility model is an easily detachable LED indicator bulb, comprising an LED bulb 4, a mounting base 1, a locking mechanism 2, and a driving mechanism 3.

[0034] The top of the mounting base 1 is detachably connected to an LED bulb 4, and a plug-in post 201 is fixedly installed on the top of the mounting base 1. The plug-in post 201 provides a coaxial positioning reference for the LED bulb 4 to ensure that the axes of the two are aligned during installation. A snap-fit ​​ring 202 is fitted on the outer bottom of the LED bulb 4. The snap-fit ​​ring 202 is an annular protrusion structure and serves as a vertical locking engagement surface, which cooperates with the hook-shaped structure of the L-shaped locking rod 204 to form a mechanical snap-fit. The top of the mounting base 1 has a mounting groove adapted to the plug-in post 201 to receive the plug-in post 201 and enhance coaxial positioning. The locking mechanism 2 includes four L-shaped locking rods 204 distributed in a square to ensure that the LED bulb 4 is subjected to uniform force in the circumference. The horizontal end of the L-shaped locking rod 204 is a hook-shaped structure adapted to the snap-fit ​​ring 202 and mechanically engages with the annular protrusion of the snap-fit ​​ring 202. The horizontal section of the L-shaped locking rod 204 is deformable so that it can be compressed radially by the snap ring 202 during installation to reduce insertion resistance. The end of its horizontal section is connected to an arc-shaped rod 203 to increase the contact area and fit with the snap ring 202. Its vertical section passes through the mounting base 1 and is fixed to the outside of the limiting plate 205 to transmit the elastic force of the compression spring 206 and provide axial constraint. The limiting plate 205 is a square plate to fit the movable cavity and prevent the L-shaped locking rod 204 from rotating or tilting. The movable cavity is provided inside the mounting base 1 to provide vertical guiding space for the limiting plate 205. The compression spring 206 is sleeved on the outside of the vertical section of the L-shaped locking rod 204 to provide the L-shaped locking rod 204 with a continuous downward elastic thrust. The compression spring 206 always applies an elastic thrust to the L-shaped locking rod 204 towards the bottom of the mounting base 1 to ensure that the locking posture is maintained when there is no external force. The two ends of the compression spring 206 abut against the limiting plate 205 and the inner wall of the mounting base 1 respectively to make the elastic force act stably in the axial direction.

[0035] The drive mechanism 3 includes a rotating ring 301 as the control core for horizontal locking. The rotating ring 301 is rotatably sleeved on the outside of the mounting base 1 to achieve free circumferential rotation. Its outer peripheral wall is fixedly connected to an extension plate 303 as a human-machine interaction operation part for easy gripping and force application. The top is provided with a slot 302 adapted to the vertical end of the L-shaped locking rod 204 to mechanically engage with the vertical end of the L-shaped locking rod 204. The outer side of the L-shaped locking rod 204 is slidably embedded in the slot 302 to allow vertical movement and constrain circumferential rotation.

[0036] The mounting base 1 has a concave stop groove 304 on its outside to provide circumferential travel restriction for the extension plate 303. The bottom of the mounting base 1 is fixed with a return spring 305 to provide axial return thrust for the rotating ring 301. The end of the return spring 305 away from the bottom of the mounting base 1 abuts against the rotating ring 301 to ensure that the elastic force acts directly on the axial direction of the rotating ring 301. The outer side of the extension plate 303 slides inside the concave stop groove 304 to move under the constraint of the stop groove. The shapes of the two ends of the concave stop groove 304 are adapted to the shape of the extension plate 303 so that the extension plate 303 automatically locks in the locked / unlocked position to form a mechanical limit.

[0037] Working principle: When installing LED bulb 4, first, align the bottom of LED bulb 4 with the insertion post 201 on the top of the mounting base 1 and insert it. The four L-shaped locking rods 204 arranged in a square on the top of the mounting base 1 have hook-like structures at their horizontal ends that correspond to the snap-fit ​​ring 202 on the outer ring protrusion at the bottom of the LED bulb 4. During installation, the L-shaped locking rods 204 are compressed and deformed by the snap-fit ​​ring 202, allowing the LED bulb 4 to be fully inserted into the top of the mounting base 1. Then, by pressing down on the extension plate 303, the entire rotating ring 301 moves downward, causing the compression spring 206 to recover its deformation and move the limiting plate 205 and the L-shaped locking rods 204 downward. This allows the hook-like structure of the horizontal section of the L-shaped locking rod 204 to engage with the arc-shaped rod 203 on the snap-fit ​​ring 202, so that the arc-shaped rod 203 is fully embedded in the horizontal end of the L-shaped locking rod 204. Then, by rotating... The extension plate 303 drives the rotating ring 301 to rotate until the slot 302 on the rotating ring 301 corresponds to the vertical section of the L-shaped locking rod 204. That is, when the extension plate 303 moves from one end of the concave stop groove 304 to the other end, the extension plate 303 is released. Under the push of the return spring 305, the rotating ring 301 and the extension plate 303 move upward and are precisely engaged with the L-shaped locking rod 204. In this way, the vertical restriction of the fastening ring 202 and the horizontal restriction of the rotating ring 301 ensure that the LED bulb 4 can remain stable in both dimensions after insertion.

[0038] To disassemble and maintain the LED bulb 4, the operator manually rotates the extension plate 303 of the ring 301 downwards, causing the ring 301 to move downwards. This separates the slot 302 on the ring 301 from the vertical section of the L-shaped locking rod 204. Rotating the extension plate 303 further rotates the ring 301, causing the slot 302 to misalign with the vertical section of the L-shaped locking rod 204. At this point, the limiting plate 205 is released, and the ring 301 moves upwards under the force of the return spring 305, pushing out the L-shaped locking rod 204. This causes the hook-like structure of the horizontal section of the L-shaped locking rod 204 to gradually disengage from the latching ring 202, and the compression spring 206 is compressed again. When the extension plate 303 slides to the other end of the concave stop groove 304 and engages, the hook-like structure of the horizontal section of the L-shaped locking rod 204 completely separates from the latching ring 202. The LED bulb 4 can then be pulled upwards, completing the disassembly. Through this series of mechanical structures, the LED indicator bulbs are made easy to disassemble and stably installed.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
