[0025] Below, in conjunction with specific implementation methods, the utility model is further described:

[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1-5 A waterproof light-guiding device is shown, comprising a shell 10, a light-guiding column 20 and a light source assembly, wherein the shell 10 has a light-guiding hole 11 and a mounting groove 12, wherein the light-guiding hole 11 is located at the top of the shell 10 and is connected to the mounting groove 12, and the light-guiding column 20 has a mounting end 21 and a light-guiding end 22, wherein during assembly, the mounting end 21 is embedded in the mounting groove 12, and the light-guiding end 22 extends into the light-guiding hole 11 after the mounting end 21 is embedded in the mounting groove 12, and a sealing rib 211 is arranged on the outer periphery of the light-guiding column 20, the sealing rib 211 is arranged along the periphery of the mounting end 21, and is used to abut against the inner wall of the mounting groove 12, and then the light source assembly is installed at the end of the light-guiding column 20 away from the mounting groove 12, and is used to release the light source.

[0029] On the basis of the above structure, during assembly, the mounting end 21 of the light guide column 20 can be embedded in the mounting groove 12 of the shell 10, and then the sealing rib 211 on the outer periphery of the mounting end 21 can be pressed against the inner wall of the mounting groove 12, so that the sealing rib 211 can be used to seal the gap between the outer periphery of the mounting end 21 and the inner wall of the mounting groove 12, so that the mounting end 21 is not easy to loosen after being embedded in the mounting groove 12, and has good sealing performance, and then the light source assembly is installed to the other end of the light guide column 20 away from the mounting groove 12 (that is, the bottom of the mounting end 21) to release the light source through the light source assembly. Since the light guide end 22 of the light guide column 20 extends into the light guide hole 11 after the mounting groove 12, the light released by the light source assembly can pass through the mounting end 21 and the light guide end 22 in turn, and finally be emitted to the outside through the light guide hole 11 for lighting indication.

[0030] In addition, since the sealing rib 211 is sealed in the gap between the outer periphery of the mounting end 21 and the inner wall of the mounting groove 12, if water flows into the mounting groove 12, the water will not flow from the mounting groove 12 to the light source assembly due to the presence of the sealing rib 211, thereby reducing the risk of the light source assembly getting damp. The entire structure has good sealing properties and an excellent waterproof effect.

[0031] In the field of maritime communications, communication equipment often needs to integrate many indicator lights, and the crew knows the current working status of the equipment through flashing lights. When assembling existing indicator lights, the light emitted by the LED lamp is usually transmitted to the surface of the shell through a light guide column 20, and then the gap around the light guide column 20 is sealed with adhesive to prevent water on the ship from entering the LED lamp through the assembly gap between the light guide column 20 and the shell, causing the LED to get damp. However, the glue dispensing process results in a long product assembly cycle, and it is not easy to disassemble and assemble in the later stage, making maintenance and repair difficult.

[0032] Therefore, when using the waterproof light-guiding device of the utility model, after the mounting end 21 of the light-guiding column 20 is embedded in the mounting groove 12 of the shell 10, the light-guiding end 22 of the light-guiding column 20 can extend into the light-guiding hole 11 to guide light. Since the sealing rib 211 on the periphery of the mounting end 21 of the light-guiding column 20 abuts against the inner wall of the mounting groove 12, the sealing rib 211 can seal the gap between the periphery of the mounting end 21 and the inner wall of the mounting groove 12, thereby reducing the risk of water flowing into the mounting groove 12 and then flowing into the light source assembly, thereby reducing the risk of the light source assembly being damaged by moisture, and improving the sealing and waterproofness of the entire device. In addition, since the light-guiding column 20 is directly embedded in the mounting groove 12, there is no need for glue dispensing processing, which shortens the product assembly cycle and makes later disassembly and assembly more convenient.

[0033] It should be noted that the light guide column 20 in the utility model is made of light-transmitting materials, such as transparent plastic or glass, so that it can guide the light from the light source to the outside for use, and the sealing rib 211 can be formed on the outer periphery of the mounting end 21 with a sealing rubber ring such as rubber or silicone, so that it can seal the gap between the mounting groove 12 and the outer periphery of the mounting end 21, and can also reduce the risk of the mounting end 21 slipping from the mounting groove 12 after the light guide column 20 is installed. The assembly is tight and the waterproof effect is good.

[0034] The light source assembly can be formed by lamp beads such as LED lamps or incandescent lamps. During the specific assembly, the light source assembly can be installed on the bottom of the mounting end 21 of the light guide column 20 by means of a snap connection or a detachable connection such as a connector (such as a screw or a screw) after the light guide column 20 and the shell 10 are assembled. Or it can be connected to the bottom of the shell 10 to cover the mounting groove 12 and stay away from the mounting groove 12. In this way, even if water flows into the mounting groove 12, due to the presence of the sealing rib 211, the water flow cannot pass through the sealing rib 211 and enter the light source assembly, and the entire structure is more waterproof.

[0035] Furthermore, a plurality of light guide columns 20 are provided. When a plurality of light guide columns 20 are provided, the housing 10 also has a plurality of light guide holes 11 and a plurality of mounting grooves 12. The plurality of mounting grooves 12 are arranged at intervals. The plurality of light guide holes 11 correspond to the plurality of light guide grooves one by one and are connected to each other. After the mounting ends 21 of the plurality of light guide columns 20 are embedded in the plurality of mounting grooves 12 one by one, the light guide ends 22 extend into the plurality of light guide holes 11 one by one.

[0036] Specifically, since multiple indicator lights may be required to indicate the working status during use, the present embodiment has multiple light guide columns 20, light guide holes 11 and mounting grooves 12. During assembly, the three are arranged one by one. After the mounting end 21 of each light guide column 20 is installed in the mounting groove 12, the light guide end 22 of the light guide column 20 extends into the light guide hole 11. After the multiple light guide columns 20 are assembled, the light source assembly can be sealed at the bottom of the shell 10 to prevent the multiple light guide columns 20 from sliding out of the multiple mounting grooves 12. In this way, the entire device can release light from the light source through multiple light guide columns 20 at the same time, so as to be suitable for situations where multiple indicator lights are required to indicate the working status. The scope of application is wider, and it can also reduce the phenomenon of missing an indicator light or causing product defects due to repeated assembly operations using a single light guide column 20.

[0037] More specifically, based on the above structure, the light source assembly can be a single lamp board, which can simultaneously cover multiple installation slots 12 and release light into multiple light guide columns 20. Of course, the light source assembly can also be provided with multiple lamp beads or lamp bodies 30, etc., by installing multiple lamp beads or lamp bodies 30 one by one to the bottom of the installation end 21 of the light guide column 20, and the multiple lamp beads can be connected through the circuit board 31. Then, when the circuit board 31 is assembled, it can be connected to the bottom of the shell 10 in a detachable manner such as snap-on or connector connection, and also cover the multiple installation slots 12 at the same time to prevent the multiple light guide columns 20 in the multiple installation slots 12 from moving left and right or sliding out of the installation slots 12.

[0038] Of course, every two adjacent light guide columns 20 can also be connected by a connecting plate 40. After the light guide columns 20 are assembled with the shell 10, the connecting plate 40 can be connected to the bottom of the shell 10 by a snap-fit ​​connection or a detachable connection such as a connector (screws or bolts, etc.). In the same way, multiple light guide columns 20 can be connected in series.

[0039] It should be noted that the multiple mounting grooves 12 in this embodiment can be integrally formed on the shell 10, or multiple mounting plates or mounting sheets and other structures can be processed on the shell 10 and arranged at intervals so that multiple mounting grooves 12 are formed on the shell 10. The specific assembly can be based on actual needs.

[0040] Furthermore, the specific shell 10 includes a plurality of shielding sheets 13, and the plurality of shielding sheets 13 are arranged at intervals, and the interval between each adjacent two shielding sheets 13 forms a mounting groove 12; wherein, after the plurality of light columns are installed in the mounting groove 12, the plurality of shielding sheets 13 are located between each adjacent two light guide columns 20 and extend to the bottom of the light guide columns 20.

[0041] During specific assembly, a plurality of shielding sheets 13 are arranged at intervals on the shell 10 to form a mounting groove 12. Then, after the mounting end 21 is embedded in the mounting groove 12, each shielding sheet 13 can also extend between each two adjacent light guide columns 20 and extend to the bottom of the light guide column 20, so that the light between each two adjacent light guide columns 20 can be blocked by the shielding sheet 13, thereby effectively suppressing the cross-light between adjacent light guide columns 20.

[0042] More specifically, in the preferred embodiment, compared with integrally forming a plurality of installation slots 12 on the shell 10, the method in the present embodiment can be completed without mold opening, which saves production costs to a certain extent. The number of installation slots 12 can also be adjusted by adjusting the number of shielding pieces 13 according to actual conditions, and the scope of application is wider.

[0043] It should be noted that the shielding sheet 13 can be mounted to the housing 10 by gluing or welding, and can be made of a light-shielding material (such as a non-transparent plastic plate or a metal plate, etc.).

[0044] In addition, in the present embodiment, the ends of the plurality of light guide columns 20 away from the mounting groove 12 are connected by a connecting plate 40, and a plurality of snap-in grooves 41 are provided on the connecting plate 40, wherein the plurality of snap-in grooves 41 are located between each two adjacent light guide columns 20. In this way, the plurality of shielding plates 13 can be snap-into the plurality of snap-in grooves 41 respectively for locking, making the assembly more stable and convenient for assembly and disassembly.

[0045] Furthermore, grooves 212 are provided at the bottom of the mounting ends 21 of the multiple light guide columns 20. The light source assembly includes multiple lamp bodies 30 and a circuit board 31. The multiple lamp bodies 30 are installed on the circuit board 31. The multiple lamp bodies 30 are embedded in the multiple grooves 212 one by one. The circuit board 31 can cover the multiple grooves 212 after the multiple lamp bodies 30 are embedded in the multiple grooves 212.

[0046] Specifically, the light source assembly in the present embodiment includes a plurality of lamp bodies 30 and a circuit board 31, and the lamp body 30 is connected to the circuit board 31 so that the lamp body 30 can release the light source when powered on. During assembly, a plurality of lamp beads or lamp bodies 30 are installed one by one into the groove 212 at the bottom of the mounting end 21 of the light guide column 20, and then the side of the circuit board 31 away from the lamp body 30 can be connected to the bottom of the housing 10 in a detachable manner such as snap-on or connector connection, so as to simultaneously cover the plurality of grooves 212 and the plurality of mounting grooves 12, to prevent the plurality of light guide columns 20 from loosening longitudinally or slipping from the mounting grooves 12, so that the light guide column 20 can be fixed without other assistance, and the structure is stable while facilitating later maintenance.

[0047] Preferably, in the present embodiment, the plurality of lamp bodies 30 are LED lamp beads, which are more energy-efficient and environmentally friendly than incandescent lamps or other lighting lamps and have a longer service life.

[0048] Furthermore, a plurality of sealing ribs 211 are disposed on the outer peripheries of the plurality of light guide pillars 20 . The plurality of sealing ribs 211 are disposed along the peripheries of the mounting ends 21 and are spaced apart along the axial direction of the light guide pillars 20 .

[0049] In order to ensure better sealing between the outer periphery of the mounting end 21 and the inner wall of the mounting groove 12 after the multiple light guide columns 20 are installed in the mounting groove 12, a plurality of sealing ribs 211 are provided in the present embodiment. By arranging the plurality of sealing ribs 211 along the periphery of the mounting end 21 and distributing them at intervals in the axial direction of the light guide column 20, the outer periphery of the mounting end 21 and the inner wall of the mounting groove 12 can be sealed layer by layer by the plurality of sealing ribs 211, thereby strengthening the sealing between the two and achieving a better waterproof effect.

[0050] Preferably, the plurality of sealing ribs 211 are made of silicone, which has excellent sealing properties and good tensile strength and is not easily deformed or damaged, thereby making the entire structure more sealed and durable.

[0051] More specifically, the light guide column 20 in the present embodiment is made of an elastic and light-transmitting material, such as transparent silicone or transparent rubber. Thus, when the light guide end 22 of the light guide column 20 is extended into the light guide hole 11, the contact area between the light guide end 22 and the light guide hole 11 can be increased through its own elastic deformation, thereby reducing the existence of the gap and making the light guide end 22 fit tightly with the inner wall of the light guide hole 11, thereby reducing the risk of water entering the mounting groove 12 from the light guide hole 11.

[0052] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
