Detailed Embodiments

[0028] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0029] As Figures 1 to 3As shown in the figure, a lamp tube profile structure includes a tube body 1. Plug heads 2 are provided at both ends of the tube body 1. A cavity 1011 for placing electric wires is provided through the tube body 1 along the length direction. The plug head 2 includes an end cap 201. The end cap 201 is connected with an insertion plate 202. An opening 203 is provided on the upper surface of the insertion plate 202. A pressing member 204 is connected in the opening 203. The upper surface of the pressing member 204 faces the side opposite to the end cap 201 and is inclined from bottom to top to form a pressing end 2041. When the insertion plate 202 is inserted into the cavity 1011, the pressing end 2041 tightly abuts against the inner surface of the tube body 1 so that there is a pressing force between the plug head 2 and the tube body 1. In this embodiment, the plug head 2 is made of plastic material as a whole. Therefore, when the pressing member 204 is pressed, it will undergo slight deformation and movement. This change is to adapt to the pressed environment, and as Figure 2 shown, there is a reserved moving space between the periphery of the pressing member 204 and the inner edge of the opening 203. When the pressing member 204 is pressed (by the pressure of the top plate of the mounting shell 101) when inserted into the cavity 1011, the pressing member 204 will move slightly downward. Therefore, it is necessary to reserve a moving space between the pressing member 204 and the opening 203. The inclined setting of the upper surface of the pressing member 204 conforms to the gradual pushing and pressing of the top plate of the mounting shell 101. When the pressing member 204 is pushed into the cavity 1011, the pressing end 2041 of the pressing member 204 has a pressing force with the lower surface of the top plate of the mounting shell 101. Thus, while the plug head 2 and the tube body 1 are installed in a plug-in manner, the pressing force between the insertion plate 202 and the tube body 1 can be increased through the pressing member 204, so that the plug head 2 is tightly installed in the cavity 1011. The specific operation is that when the insertion plate 202 is inserted into the cavity 1011, the pressing end 2041 tightly abuts against the inner surface of the tube body 1 to fix the plug head 2, so that the connection between the plug head 2 and the tube body 1 is more firm, the plug head 2 is not easy to fall off, the installation is fast, and the structure is stable.

[0030] As Figure 4 shown, the end cap 201 is arranged in a semi-surrounding structure at the front end of the insertion plate 202. An insertion position 2011 is left between the end cap 201 and the insertion plate 202. The insertion position 2011 corresponds to the edge of the tube body 1. The insertion position 2011 extends downward to form an insertion space for inserting a light-transmitting lamp cover 3. During assembly, the insertion plate 202 is inserted into the cavity 1011, the edge of the tube body 1 is inserted into the insertion position 2011, and the light-transmitting lamp cover 3 is inserted into the insertion space, so as to install the plug head 2 and the tube body 1 as a whole.

[0031] Figures 5 to 7As shown in the figure, the tube body 1 includes an installation shell 101. The installation shell 1 is in a semi-enclosed shape. The lower end of the installation shell 1 is snap-connected to the light-transmitting lampshade 3. A support plate 102 is provided between the light-transmitting lampshade 3 and the installation shell 101. The support plate 102 includes a bottom plate 1021. On both sides of the bottom plate 1021, inclined reflective plates 1022 extend obliquely downward from top to bottom. The ends of the inclined reflective plates 1022 are connected to the installation shell 101. The inclination angle of the inclined reflective plates 1022 is α, and α is 30° to 40°. In this embodiment, α is taken as 35°. The two inclined reflective plates 1022 play a role in concentrating light, which helps to gather the light emitted to both sides to the middle.

[0032] On both sides below the bottom plate 1021, a first placement plate 1023 and a second placement plate 1024 are connected. The first placement plate 1023 and the second placement plate 1024 are arranged relatively obliquely. A placement position 1025 for installing the LED light strip is formed by surrounding between the bottom plate 1021, the first placement plate 1023 and the second placement plate 1024. When the LED light strip is installed in the placement position 1025, the bright light emitted by the LED lamp will be reflected to the light-transmitting lampshade 3 through the inclined reflective plates 1022, so that the light is concentrated in one place and the brightness of the lamp tube is improved.

[0033] On both sides of the lower end of the installation shell 101, snap connectors 1012 are provided. On both sides of the upper end of the light-transmitting lampshade 3, installation slots 301 are provided. The snap connectors 1012 are connected in cooperation with the installation slots 301, so that the installation shell 101 and the light-transmitting lampshade 3 are fixed together. It is not easy to fall off while the installation is fast, and the installation shell 101 and the light-transmitting lampshade 3 are detachably connected, which is convenient for lamp tube maintenance or replacement.

[0034] On both sides of the upper end of the installation shell 101, first rounded corners 1013 are provided. On both sides of the lower end of the light-transmitting lampshade 3, second rounded corners 302 are provided. The rounded corner design can make the corners of the installation shell 101 and the light-transmitting lampshade 3 relatively smooth, comfortable to touch, and not easy to be scratched due to sharpness.

[0035] An enhanced groove 1014 is formed by inward concavity below the first rounded corner 1013. The length direction of the enhanced groove 1014 is consistent with the length direction of the tube body 1. The enhanced groove 1014 can effectively enhance the strength and rigidity of the installation shell 101.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
