The linear light body has a strip-shaped groove parallel to the length of the linear light body on its symmetrical outer wall, and a C-shaped screw hole groove is provided at the bottom of the strip-shaped groove.
[0005] The plug has symmetrically formed locking protrusions on its inner side surface, and two mounting holes are provided on the plug.
[0006] The plug has a limiting protrusion fixed in the middle of its inner side surface, and a fitting protrusion is provided on the upper part of the inner side surface of the plug.
[0007] The inner side of the plug is attached to the end of the linear light body, the limiting protrusion is inserted into the lamp cavity of the linear light body, the locking protrusion is inserted into the strip groove, and the fitting protrusion is attached to the top surface of the linear light body and is threaded into the C-shaped screw hole groove by a screw passing through the mounting hole.
[0008] The connection between the plug and the linear light body is coated with a sealant layer.
[0009] A further preferred embodiment is that the lower part of the inner side of the plug is provided with a lens end clearance groove;
[0010] The lens end of the linear light body is inserted into the lens end edge recess.
[0011] A further preferred embodiment is that the heights of the positioning protrusion, the limiting protrusion, and the fitting protrusion are the same.
[0012] A further preferred embodiment is that the upper part of the symmetrical inner wall of the lamp cavity of the linear lamp body is provided with a light source plate slot;
[0013] The top of the symmetrical edge of the limiting protrusion is integrally formed with a stop protrusion that fits into the slot of the light source line.
[0014] The abutment protrusion is inserted into the slot of the light source board.
[0015] A further preferred embodiment is that the plug is an aluminum plug or a plastic plug.
[0016] This utility model has positive effects: The structure of this utility model is reasonably designed. Its plug is provided with a locking protrusion, a limiting protrusion and a fitting protrusion. During assembly, the locking protrusion and the limiting protrusion are locked into the corresponding slots of the linear light body, and the fitting protrusion is attached to the top surface of the linear light body.

[0022] 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.
[0023] Example
[0024] See Figures 1 to 3As shown, a snap-fit type linear light plug structure with adhesive sealing includes a linear light body 1 and a plug 2. A strip-shaped groove 3 parallel to the length of the linear light body is provided on the symmetrical outer wall of the linear light body. A C-shaped screw hole groove 4 is provided at the bottom of the strip-shaped groove. In this embodiment, the linear light body is a conventional structure of the prior art, simply applied. The plug is mainly used to seal both ends of the linear light body. The width of the strip-shaped groove can be machined and set as needed. The C-shaped screw hole groove is mainly used for positioning with the screw thread connection. The plug is an aluminum plug or a plastic plug.
[0025] In this embodiment, the plug has a locking protrusion 5 integrally formed at the symmetrical edges of its inner side surface, and the plug is provided with two mounting holes 6; in addition, a limiting protrusion 7 is fixed in the middle of the inner side surface of the plug, and a fitting protrusion 8 is provided on the upper part of the inner side surface of the plug; the locking protrusion, the limiting protrusion and the fitting protrusion are of the same height, and can be processed according to installation requirements.
[0026] During assembly, the inner side of the plug is attached to the end of the linear light body, the limiting protrusion is inserted into the lamp cavity of the linear light body, the locking protrusion is inserted into the strip groove, and the fitting protrusion is attached to the top surface of the linear light body. It is then threaded into the C-shaped screw hole groove by a screw passing through the mounting hole. The connection between the plug and the linear light body is coated with a sealant layer.
[0027] During assembly, a sealant layer is applied to the connection between the plug and the linear light body, such as the inner side of the plug, the surface of the locking protrusion, the inner wall of the mounting hole, the surface of the limiting protrusion, and the surface of the fitting protrusion. This sealant layer allows for bonding and sealing during installation, improving the sealing and waterproofing performance of the connection. Furthermore, when the external force exceeds the bonding force, the plug can be separated from the connection of the linear light body, facilitating the disassembly and replacement of the internal light source board and lens, ensuring stable and reliable operation.
[0028] In this embodiment, a lens end clearance groove 9 is provided on the lower inner side of the plug; the lens end of the linear light body is inserted into the lens end clearance groove. In this embodiment, the lens end clearance groove can also be coated with an adhesive layer to ensure the sealing and waterproofing of the connection between the lens and the plug.
[0029] In this embodiment, a light source plate slot 10 is provided on the upper part of the symmetrical inner wall of the lamp cavity of the linear lamp body; the top of the symmetrical edge of the limiting protrusion is integrally formed with a retaining protrusion 11 that fits into the light source plate slot; during assembly, the retaining protrusion is engaged in the light source plate slot. This ensures that the end cap is installed stably and reliably, preventing loosening or displacement.
[0030] This utility model has positive effects: The structure of this utility model is reasonably designed. Its plug is provided with a locking protrusion, a limiting protrusion and a fitting protrusion. During assembly, the locking protrusion and the limiting protrusion are locked into the corresponding slots of the linear light body, and the fitting protrusion is attached to the top surface of the linear light body. A sealant filling layer is injected at the connection to seal it, which helps to improve the sealing and waterproof performance of the connection between the plug and the linear light body. It is stable and reliable in use and has strong applicability.
[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
