[0017] In order to more clearly understand the technical content of the utility model, the following embodiments are specifically described in detail.

[0018] Please refer to Figures 1 to 3 as shown, which are respectively schematic external views of the elastic light-transmitting lamp cap and the light-transmitting inner column in the light guide column of the utility model.

[0019] In one embodiment, the light guide column is arranged in the indicating lamp through hole on the surface of the electronic device shell. It comprises an elastic light-transmitting lamp cap 1 and a light-transmitting inner column 2. The elastic light-transmitting lamp cap 1 can be made of silica gel material, and the light-transmitting inner column 2 can be made of PC material. The light source is arranged inside the light-transmitting inner column 2. The elastic light-transmitting lamp cap 1 is embedded in the indicating lamp through hole, and the light-transmitting inner column 2 is fixed on the inner side of the shell. The light-transmitting inner column 2 abuts against the elastic light-transmitting lamp cap 1 from the inner side to the outer side of the shell, and the elastic light-transmitting lamp cap 1 is tightly pressed in the indicating lamp through hole.

[0020] In a preferred embodiment, the elastic light-transmitting lamp cap 1 includes a lamp cap body 11 and an embedding groove 12 protruding outward from the lamp cap body 11. The lamp cap body 11 has a cylindrical inner contour. The light-transmitting inner column 2 includes a light source cylinder 21 and a rib 22 provided on the outer side of the light source cylinder 21, and the light source is arranged inside the light source cylinder 21. The light source cylinder 21 presses against and closely adheres to the cylindrical inner contour of the lamp cap body 11, so that the rib 22 is embedded into the embedding groove 12, and then the embedding groove 12 is slightly deformed and protrudes outward so as to tightly press against the indicator light through-hole. The lamp cap body 11 is located inside the shell, and the outer side of the embedding groove 12 serves as a light-transmitting surface of the light guide column on the outer surface of the electronic device shell.

[0021] In a more preferred embodiment, the light-transmitting inner column 2 further includes a positioning tongue 23, and the extending direction of the positioning tongue 23 is perpendicular to the central axis of the light source cylinder 21. A screw hole 24 is formed in the positioning tongue 23, and the light-transmitting inner column 2 can be fixed to the inner side of the shell by using a screw through the screw hole 24.

[0022] In practical applications, it is very convenient to install the light guide column of the present invention. First, place the elastic light-transmitting lamp cap at the position inside the indicator light through-hole, so that the embedding groove is embedded into the indicator light through-hole. Then, closely place the light-transmitting inner column on the inner side of the elastic light-transmitting lamp cap, and fix the light-transmitting inner column and the shell by using a plastic screw. At this time, the light-transmitting inner column closely adheres to the inner side (back surface) of the elastic light-transmitting lamp cap, and slightly presses the elastic light-transmitting lamp cap outward, so that the embedding groove is slightly deformed and completely embedded into the indicator light through-hole, thereby improving the sealing performance between the light guide column and the shell and preventing glue leakage. Then, install the light source in the light-transmitting inner column to complete the entire installation process.

[0023] The light guide column adopting the present invention includes an elastic light-transmitting lamp cap and a light-transmitting inner column. The elastic light-transmitting lamp cap is embedded in the indicator light through-hole, and the light-transmitting inner column is fixed to the inner side of the shell. The light-transmitting inner column abuts against the elastic light-transmitting lamp cap from the inner side to the outer side of the shell, and the elastic light-transmitting lamp cap tightly presses against the indicator light through-hole. Thereby, it can be ensured that the elastic light-transmitting lamp cap is in close contact with the shell around the indicator light through-hole, improving the sealing performance between the light guide column and the shell. Moreover, the light guide column of the present invention has a simple structure, is convenient to install, and has a wide application range.

[0024] In this specification, the present invention has been described with reference to its specific embodiments. However, it is obvious that various modifications and transformations can still be made without departing from the spirit and scope of the present invention. Therefore, the specification and drawings should be regarded as illustrative rather than restrictive.
