Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically a structure in which a side-rotating switch and an LED light are placed on the same side. Background Technology

[0002] A flashlight is a handheld electronic lighting tool. Depending on different usage needs, existing flashlight products have shown a wide variety of changes in appearance, performance, and functions.

[0003] To meet the needs of close-range floodlighting, most flashlights on the market now have side lights added to the side. The function control buttons and side lights are usually placed at opposite ends of the lighting product. The existing flashlight body and head are generally assembled with threads, which makes it difficult to achieve precise and specific angle assembly during the assembly process. After assembly, it is difficult to ensure the consistency of the relative positions of the head and body, which affects the product's appearance and makes it difficult to achieve specific angle illumination from the side light. Therefore, it cannot meet the growing needs of users. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide an arrangement structure in which the side rotary switch and the LED light are placed on the same side.

[0005] The technical solution adopted by this utility model is as follows: an arrangement structure in which a side-rotating switch and an LED light are placed on the same side, including a cylindrical head and a cylindrical body, wherein the cylindrical head has a receiving cavity with a rear opening, a limiting ring is provided in the receiving cavity, and a positioning protrusion is provided on the limiting ring, and a positioning groove is formed by the inward indentation of the inner edge of the front end of the cylindrical body, and the cylindrical body can be screwed in and / or screwed out relative to the cylindrical head. When the cylindrical body is screwed in to a certain depth, the inner end face of the positioning groove abuts against the positioning protrusion to limit the relative position between the cylindrical body and the cylindrical head.

[0006] In a preferred embodiment, the inner wall of the receiving cavity is provided with an internal thread, and the outer wall of the cylinder is provided with an external thread that matches the internal thread.

[0007] In a preferred embodiment, the positioning groove and the positioning protrusion are respectively located in front of the external thread and the internal thread, and the distance between the positioning groove and the external thread is the same as the distance between the positioning protrusion and the internal thread.

[0008] In a preferred embodiment, the positioning groove is an arc-shaped groove, the length of the positioning groove is greater than the length of the positioning protrusion, and the positioning protrusion is located within the rotation trajectory of the positioning groove.

[0009] In a preferred embodiment, the limiting ring and the positioning protrusion are integrally formed.

[0010] In a preferred embodiment, the cylinder body is a hollow cylinder.

[0011] In a preferred embodiment, a side-rotating switch, a tail switch, and an auxiliary LED light are provided between the cylinder head and the cylinder body, and the side-rotating switch, tail switch, and auxiliary LED light are arranged on the same axis or staggered.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: positioning protrusions and positioning grooves are designed on the end faces of the cylinder head and cylinder body to limit their relative positions. During the process of the cylinder body being screwed into the cylinder head, the mutual constraint of the positioning mechanism and the threaded part can realize the assembly operation of the cylinder body and the cylinder head at a specific angle. After assembly, the consistency of the relative positions of the appearance features of the cylinder head and the cylinder body can be guaranteed, which has advantages that current lighting products do not have.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] A layout structure in which the side-rotating switch and the LED light are placed on the same side, as shown in the reference. Figure 1-4The device includes a head 1 and a body 4. The body 4 is a hollow cylinder. The head 1 has a receiving cavity with an open rear end. A limiting ring 2 is provided in the receiving cavity, and a positioning protrusion 7 is provided on the limiting ring 2. The inner edge of the front end of the body 4 is recessed inward to form a positioning groove 5. The body 4 can be screwed into and / or screwed out relative to the head 1. When the body 4 is screwed inward to a certain depth, the inner end face of the positioning groove 5 abuts against the positioning protrusion 7 to limit the relative position between the body 4 and the head 1. The inner wall of the receiving cavity is provided with an internal thread 3, and the outer wall of the body 4 is provided with an external thread 6 that matches the internal thread 3. Positioning protrusion 7 and positioning groove 5 are designed on the end faces of the head 1 and the body 4 to limit their relative position. During the process of the body 4 being screwed into the head 1 through the threaded part, the mutual constraint of the positioning protrusion 7, the positioning groove 5 and the threaded part can realize the assembly operation of the body 4 and the head 1 at a specific angle. After assembly, the consistency of the relative position of the appearance features of the head 1 and the body 4 can be guaranteed.

[0020] Furthermore, a side-rotating switch 8, a tail switch 10, and an auxiliary LED light 9 are provided between the head 1 and the body 4 (with a back-hanging bracket). The side-rotating switch 8, the tail switch 10, and the auxiliary LED light 9 are preferably arranged on the same axis. Placing the side-rotating switch 8, the tail switch 10, and the auxiliary LED light 9 on the same side facilitates one-handed operation under specific clamping methods (fixed to the backpack strap and waist belt), realizing the directional lighting function at a specific angle and freeing up both hands.

[0021] In other embodiments, the side-rotating switch 8, the tail switch 10, and the auxiliary LED light 9 can also be arranged at any different angles, which is not limited here.

[0022] Furthermore, the positioning groove 5 and the positioning protrusion 7 are located in front of the external thread 6 and the internal thread 3, respectively. The distance between the positioning groove 5 and the external thread 6 is the same as the distance between the positioning protrusion 7 and the internal thread 3. The positioning groove 5 is an arc-shaped groove, and the length of the positioning groove 5 is greater than the length of the positioning protrusion 7. The positioning protrusion 7 is located within the rotation trajectory of the positioning groove 5. With the above design, when the cylinder body 4 is assembled onto the cylinder head 1, the external thread 6 will be screwed into the internal thread 3 first. During the screwing process, the positioning protrusion 7 will enter the position of the positioning groove 5. When a specific angle is reached, the positioning protrusion 7 will abut against the positioning groove 5, thereby realizing the assembly operation at a specific angle.

[0023] Furthermore, the limiting ring 2 and the positioning protrusion 7 are integrally formed structures, which can ensure the strength between the limiting ring 2 and the positioning protrusion 7, while also saving mold opening and manufacturing costs. The limiting ring 2 has a hole in the middle to allow the conductive spring in the PCB motherboard inside the cylinder head 1 to protrude.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
