Description

Technical Field

[0001] This utility model relates to the field of flashlight technology, and in particular to a sliding rail high-intensity flashlight. Background Technology

[0002] As we all know, flashlights are mainly used to provide illumination. Due to their advantages such as portability, low power consumption, and unrestricted use, they are widely used. However, traditional flashlights have significant limitations. They require continuous manual operation, and when users must concentrate on their work, it is difficult to maintain stable lighting. In scenarios where lighting is crucial, such as nighttime cycling, traditional flashlights are easily limited by body movements, which can lead to safety accidents and necessitates improvement. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing a sliding rail high-intensity flashlight that achieves stable illumination.

[0004] In view of this, the present invention provides a sliding rail high-power flashlight, comprising:

[0005] A flashlight body, the flashlight body being used for illumination;

[0006] A holding device is connected to the flashlight body. The holding device includes a slide rail for connecting to a slide rail.

[0007] In this technical solution, the shape of the slide rail matches the shape of the slide rail. The slide rail can be fixed on the handlebars of a bicycle or on a cycling hat. By sliding the slide rail onto the slide rail, the flashlight body can be fixed, eliminating the need for the operator to hold it and freeing up the user's hands.

[0008] Furthermore, the holding device has a mounting hole that matches the outer periphery of the flashlight body, the flashlight body has a threaded hole, the holding device has a connecting hole, the locking bolt passes through the connecting hole and connects with the threaded hole, the outer periphery of the flashlight body is also provided with a flattened surface, the inner wall of the mounting hole is provided with a positioning plane that matches the flattened surface, and the angle between the threaded hole and the flattened surface in the circumferential direction is the same as the angle between the positioning plane and the connecting hole in the circumferential direction.

[0009] In this technical solution, the flashlight body is inserted into the mounting hole on the holding device. When inserting, the flattened surface is aligned with the positioning plane, so that the threaded hole and the connecting hole are aligned. This facilitates the connection of the locking bolt through the connecting hole and the threaded hole. By connecting the locking bolt through the connecting hole and the threaded hole, the flashlight body and the holding device can be fixedly connected. The matching of the positioning plane and the flattened surface can prevent the fixing structure between the holding device and the flashlight body from loosening due to loosening of the threads caused by environmental vibration.

[0010] Furthermore, the flashlight body includes:

[0011] The outer cylinder has a lampshade at one end, and a concave lens is provided on the cross-section of the lampshade.

[0012] An inner cylinder is slidably fitted inside an outer cylinder, and a lamp holder is provided at one end of the inner cylinder near the lamp cover.

[0013] The tail cap is sleeved on the outside of the inner cylinder and threadedly connected to the end of the inner cylinder away from the lamp head.

[0014] In this technical solution, the inner cylinder is assembled inside the outer cylinder. The inner cylinder is moved by moving the tail cap, which in turn moves the lamp head inside the outer cylinder, changing the relative distance between the lamp head and the concave lens, thus achieving stepless adjustment of the light from a focused state to a defocused state.

[0015] Furthermore, an annular positioning groove is provided on the outer side of the inner cylinder, and an O-ring seal is installed in the groove.

[0016] In this technical solution, the elastic deformation of the O-ring seal fills the gap between the outer and inner cylinders, preventing liquid from flowing in and causing safety hazards. Furthermore, by utilizing the inherent frictional properties of the O-ring seal material, a stable frictional interface is formed between the outer and inner cylinders, effectively offsetting the axial displacement of the inner cylinder caused by external forces such as gravity and vibration.

[0017] Furthermore, the inlet of the outer cylinder near the lamp cover is stepped, with a large-diameter section and a small-diameter section. The outer periphery of the inner cylinder near the lamp head is provided with a limiting annular boss. The outer diameter of the limiting annular boss is larger than the inner diameter of the small-diameter section and smaller than the large-diameter section. The outer diameter of the tail cap is larger than the outer diameter of the outer cylinder.

[0018] In this technical solution, when the limiting annular boss contacts the end face of the small-diameter section of the outer cylinder, it prevents the inner cylinder from moving towards the tail cover. When the tail cover contacts the outer cylinder, it prevents the inner cylinder from moving towards the lampshade, thus limiting the axial displacement of the lamp head within the outer cylinder. The moving distance is the contact distance between the limiting annular boss and the end face of the small-diameter section when the tail cover contacts the outer cylinder.

[0019] Furthermore, the end face of the tail cap away from the inner tube is provided with a button and a positioning protrusion higher than the button. The button is used to control the brightness of the flashlight.

[0020] In this technical solution, the support surface formed by the positioning boss provides protection for the button, preventing accidental button presses that could alter the flashlight's illumination state when the flashlight is accidentally squeezed.

[0021] Furthermore, the slide rail is threadedly connected to a fastening bolt on its side, with the small end of the fastening bolt extending to the inside of the slide rail.

[0022] In this technical solution, the slide rail and the slide track slide together. When the slide rail slides to the designated position on the slide track, the fastening bolt is tightened to lock the slide rail on the slide track, preventing the slide rail from shifting and affecting the stability of the lighting.

[0023] Furthermore, the outer cylinder has axial anti-slip texture on the outer side near the lampshade.

[0024] In this technical solution, the axial anti-slip texture increases the tangential friction force when the fingers grip, making it easier to install and remove the outer cylinder and the lamp cover.

[0025] Furthermore, the tail cap has axial anti-slip grooves on the outer side near the inner cylinder.

[0026] In this technical solution, the axial anti-slip texture increases the tangential friction force when the fingers grip, making it easier to install and remove the inner cylinder and the tail cap.

[0027] Furthermore, an annular anti-slip groove is provided on the outer side of the end of the tail cap away from the inner cylinder.

[0028] In this technical solution, by increasing the contact area, the radial friction force when the fingers are gripping is enhanced, thereby reducing the risk of slippage when adjusting the tail cap.

[0029] The beneficial effects of this utility model are:

[0030] 1. Insert the flashlight body into the mounting hole on the holding device. When inserting, make sure the flattened surface aligns with the positioning plane. This ensures that the threaded hole and the connecting hole are aligned, facilitating the connection of the locking bolt through the connecting hole and the threaded hole. By connecting the locking bolt through the connecting hole and the threaded hole, the flashlight body and the holding device can be fixedly connected. The matching of the positioning plane and the flattened surface can prevent the fixing structure between the holding device and the flashlight body from loosening due to environmental vibration. This meets the positioning requirements of different usage scenarios.

[0031] 2. Nowadays, most flashlights on the market adjust the focus by rotating or stretching the lamp head. When the flashlight is in use, the tail cap is usually closer to the user. By moving the tail cap, the inner tube moves, which in turn moves the lamp head inside the outer tube, changing the relative distance between the lamp head and the concave lens. This allows the user to more conveniently and quickly achieve stepless adjustment of the light from focused to defocused.

[0032] 3. The elastic deformation of the O-ring seal fills the gap between the outer and inner cylinders, preventing liquid from flowing in and causing safety hazards. It also utilizes the inherent frictional properties of the O-ring seal material to form a stable frictional interface between the outer and inner cylinders, effectively offsetting the axial displacement of the inner cylinder caused by external forces such as gravity and vibration.

[0033] 4. The support surface formed by the positioning boss forms a physical barrier around the button, preventing accidental button presses that could alter the flashlight's illumination status when the flashlight is accidentally squeezed. Attached Figure Description
