Description

Technical Field

[0001] This utility model relates to the field of lamp barrel technology, and in particular to an RGB lamp barrel with a pressure wire structure. Background Technology

[0002] An RGB downlight is a downlight that integrates red, green, and blue LED beads. Through electronic control, these three colors can be mixed in different proportions to create light of almost any color (including white light).

[0003] The downlight connects to the power supply and the control unit inside the downlight via a power cord. The downlight also requires a pressure plate to secure the power cord, ensuring a firm, safe, and reliable connection. For example, Chinese Patent Publication No. CN207569703U discloses a non-isolated power supply type integrated downlight, including a downlight housing, a circuit board inside the housing, several LED patches on the circuit board, a non-isolated power supply on the circuit board, a reflector on the housing, a light-transmitting cover on the reflector, a back cover on the right side of the housing, and a pressure plate on the back cover. The non-isolated power supply is electrically connected to each LED patch. The end connecting the reflector and the light-transmitting cover has m slots, where m is greater than 1. The light-transmitting cover is a circular horizontal plate with a smooth surface, and its edge has m mounting clips corresponding to each slot. This invention effectively reduces installation complexity, increases service life, and lowers production costs.

[0004] In actual operation, the wire clamping cover is fixed to the back cover with screws to clamp the wire. However, considering that the wire clamping cover may break after long-term use or the teeth of the wire clamping cover used to clamp the power cord may wear out, the wire clamping cover cannot be quickly disassembled and replaced, which makes it less practical. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to quickly disassemble and replace the wire clamping cover, and to propose an RGB lamp tube with a wire clamping structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design an RGB lamp tube with a pressure wire structure, including a top shell, a light-emitting component and a fixing component connected to the top of the top shell, a bottom shell connected to the bottom of the top shell, a control unit built into the bottom shell, and a power cord connected to the control unit; The bottom of the lower shell is detachably connected to a wire clamping cover via a connecting assembly. The connecting assembly also includes a locking structure, which circumferentially locks the wire clamping cover to clamp the power cord.

[0007] Furthermore, a threading cavity is provided on one side of the bottom of the lower shell, and a pressure cap is connected to the opening side of the threading cavity. The free end of the pressure cap and the outer wall of the threading cavity are provided with interlocking pressure teeth.

[0008] Furthermore, the connecting assembly includes two paddles, and the lower end face of the lower shell is provided with receiving grooves on both sides, as well as a stepped groove communicating with the threading cavity. The paddles are slidably connected in the receiving grooves, and the paddles are slidably connected to the insertion part by a compression spring in the stepped grooves.

[0009] Furthermore, the bottom cover for pressing the wire is provided with connecting parts on both sides of the rotating end, and the wire-passing cavity is also provided with relief grooves that communicate with the stepped grooves on both sides, and the connecting parts are placed in the relief grooves.

[0010] Furthermore, the end of the connecting part is provided with a guide slope, and the connecting part slides and inserts into the insertion part through the guide slope.

[0011] Furthermore, the locking structure includes a protrusion, at least one of the plug-in portions has the protrusion on its periphery, the end of the connecting portion has a locking groove, and the protrusion is inserted into the locking groove.

[0012] Furthermore, a smooth end is formed between the end of the insertion portion and the protrusion, the smooth end is inserted into the connecting portion, and the protrusion abuts against the end wall of the connecting portion.

[0013] The RGB lamp tube with a wire pressing structure proposed in this utility model has the following advantages: In this utility model, the lower bottom shell and the wire pressing bottom cover are fixed by two plug-in connecting parts. On the one hand, the wire pressing bottom cover can be directly connected to the plug-in part by the guide slope at both ends through the contact sliding method, without having to move the plug-in parts on both sides to make room. When the wire pressing bottom cover is connected to the plug-in part, the connecting part and the smooth end can be rotated to directly rotate the wire pressing bottom cover to close it. After closing, the wire pressing bottom cover is circumferentially locked by the locking structure. On the other hand, by moving the levers on both sides, the bottom cover of the wire clamp can be disassembled. This disassembly method prevents the need to replace the entire downlight in case the bottom cover is damaged or worn, thus avoiding waste. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 An RGB lamp tube with a pressure wire structure includes a top shell 1, a light-emitting component 2 and a fixing component 3 connected to the top of the top shell 1, a bottom shell 4 connected to the bottom of the top shell 1, a control unit built into the bottom shell 4, and a power cord 5 connected to the control unit. The bottom of the lower shell 4 is detachably connected to a wire pressing cover 7 via a connecting component 6. The connecting component 6 also includes a locking structure 8. The wire pressing cover 7 is circumferentially locked by the locking structure 8 to press the power cord 5.

[0018] In some embodiments, the lamp tube is existing technology. The light-emitting component 2 generally includes a diffuser plate, light-emitting paper, a lamp board, and a lamp body. The fixing component 3 includes a torsion spring and an ear bracket. The ear bracket is rotatably connected to both sides of the top shell 1 through the torsion spring. The ear bracket and the lamp body are fixed in the ear slot. The specific structure is not described in detail here. Specifically, the bottom cover 7 is used to press and fix the power cord 5 together with the bottom shell to prevent the power cord 5 from breaking due to pulling.

[0019] Furthermore, a threading cavity 41 is provided on one side of the bottom of the lower shell 4. A pressure bottom cover 7 is connected to the opening side of the threading cavity 41. The free end of the pressure bottom cover 7 and the outer wall of the threading cavity 41 are provided with interlocking pressure teeth 42.

[0020] It should be added that the upper and lower pressure teeth 42 are not completely closed with a tight fit. Ideally, there is a certain amount of engagement gap between the upper and lower pressure teeth 42. Furthermore, because the surface of the power cord 5 is covered with a rubber protective layer, the power cord 5 is pressed by causing a slight deformation of the rubber protective layer through compression.

[0021] Furthermore, the connecting component 6 includes two levers 61, and the lower end face of the lower shell 4 is provided with receiving grooves 43 on both sides, as well as a stepped groove 44 communicating with the threading cavity 41. The levers 61 are slidably connected in the receiving grooves 43, and the levers 61 are slidably connected to the insertion part 63 in the stepped groove 44 by a compression spring 62.

[0022] More specifically, the bottom cover 7 for pressing the wire is provided with connecting parts 64 on both sides of the rotating end, wherein the wire threading cavity 41 is also provided with relief grooves 45 that communicate with the stepped groove 44 on both sides, and the connecting parts 64 are placed in the relief grooves 45.

[0023] In this embodiment, as Figure 4 As shown, the cross-section of the plug part 63 is T-shaped. The compression spring 62 is sleeved around the rod-shaped part of the plug part 63, and the two ends of the compression spring 62 abut against the annular protrusion of the plug part 63 and the inner wall of the stepped groove 44, respectively. The compression spring 62 is used to drive the plug part 63 to reset. Specifically, the toggle block 61 is used to drive the plug part 63 to move, and can be used to unlock the wire clamping bottom cover 7. Also, the clearance groove 45 is used to avoid the connection part 64.

[0024] In general, the end of the connecting part 64 is provided with a guide slope 641, and the connecting part 64 slides and inserts into the insertion part 63 through the guide slope 641.

[0025] It is worth mentioning that, such as Figure 2 As shown, the bottom cover 7 of the wire pressing can directly contact and slide against the insertion part 63 through the guide slope 641. The insertion part 63 slides under force to avoid it. When it is inserted into place, because the protrusion 81 and the locking groove 82 are misaligned, the smooth end 631 is rotatably connected in the connection part 64. At this time, the bottom cover 7 of the wire pressing can be rotated freely. Specifically, when the bottom cover 7 is closed, the insertion part 63 is inserted into the connecting part 64 under the action of the compression spring 62, and the protrusion 81 is engaged in the locking groove 82, so that the bottom cover 7 can be circumferentially locked. The insertion part 63 itself is circumferentially locked under the action of the protrusion 81.

[0026] Finally, the locking structure 8 includes a protrusion 81, at least one of the plug-in portions 63 is provided with the protrusion 81 on its periphery, the end of the connecting portion 64 is provided with a locking groove 82, and the protrusion 81 is inserted into the locking groove 82.

[0027] Furthermore, a smooth end 631 is formed between the end of the insertion part 63 and the protrusion 81, the smooth end 631 is inserted into the connecting part 64, and the protrusion 81 abuts against the end wall of the connecting part 64.

[0028] Working method: During operation, after adjusting the position of the power cord 5, the bottom cover 7 is installed first. The bottom cover 7 slides against the plug part 63 through the guide slopes 641 on both sides. The plug part 63 slides under force to avoid it. After plugging in, because the protrusion 81 and the locking groove 82 are misaligned, the smooth end 631 is rotatably connected in the connecting part 64. At this time, the bottom cover 7 can be rotated freely. Then, when the bottom cover 7 is closed, the plug part 63, under the action of the compression spring 62, cooperates with the protrusion 81 to circumferentially lock the bottom cover 7, and the bottom cover 7 cooperates with the compression teeth 42 on the lower shell 4 to press the power cord 5. Finally, by simultaneously moving the levers 61 on both sides, the plug part 63 and the connecting part 64 are separated, allowing the wire clamping bottom cover 7 to be disassembled and replaced.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
