Description

Technical Field

[0001] This utility model relates to the field of flashlight technology, and more specifically, to a rotating back clip structure and a flashlight. Background Technology

[0002] Flashlights, as ordinary lighting devices, are generally used in places where there are no other lighting devices or where it is inconvenient to use a power source. They are widely used in places such as exploration, tourism, mining, and homes.

[0003] Some existing flashlights with clip-on backs have a rigid and non-rotatable connection between the clip and the flashlight housing, allowing them to be clipped to pockets, bag straps, or MOLLE systems in a fixed orientation (usually with the lamp head pointing up or down). This prevents users from changing the lamp head's orientation to a specific angle, making it impossible to flexibly adjust the angle when clipped to hat brims, backpacks, pockets, or other objects to illuminate the desired area. Furthermore, when clipped to a waist bag or chest bag, the fixed angle may cause the flashlight to dig into the body or other objects, affecting comfort. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a rotary back clip structure, including a housing and a back clip assembly disposed on one side of the housing. The back clip assembly includes a first clamping plate and a second clamping plate. A rotary connector connects the first clamping plate to the housing, allowing the first clamping plate to rotate 360 ​​degrees relative to the housing via the rotary connector. The second clamping plate is hinged to the side of the first clamping plate away from the housing. A hinge shaft connects the first and second clamping plates, and a torsion spring is sleeved on the hinge shaft. The spring force of the torsion spring clamps the first and second clamping plates together. A magnet is disposed on the side of the second clamping plate away from the first clamping plate. This rotary back clip structure is simple in structure and has low production cost. The rotatable back clip assembly improves the flashlight's clamping adaptability and versatility, enabling 360-degree multi-angle clamping and fixed lighting. The addition of a magnetic adsorption function further expands its application scenarios and provides high flexibility.

[0005] Optionally, the magnet is embedded in the second clamping plate, and the second clamping plate is provided with a mounting groove for mounting the magnet, wherein the magnet is recessed or flush with the opening of the mounting groove.

[0006] Optionally, the first clamping plate has a first axis of rotation when rotating relative to the housing, and the second clamping plate has a second axis of rotation when rotating relative to the first clamping plate, wherein the first axis of rotation is perpendicular or nearly perpendicular to the second axis of rotation.

[0007] Optionally, the rotating connector is a rivet, and the first clamping plate is provided with a groove for mounting the rivet head.

[0008] Optionally, the second clamping plate is provided with hook holes.

[0009] Optionally, the second clamping plate has a first thickening block at one end for pressing, and the magnet is embedded in the first thickening block.

[0010] Optionally, a second thickening block is provided at the end of the second clamping plate away from the first thickening block. A first plane is provided on the first thickening block, and a second plane is provided on the second thickening block. The first plane and the second plane are flush.

[0011] Optionally, the housing is provided with a back plate, and the back plate forms an angle with the first plane, the angle being 4°-8°.

[0012] Optionally, the first clamping plate has a plurality of first anti-slip protrusions on the side near the second clamping plate, and the second clamping plate has a plurality of second anti-slip protrusions on the side near the first clamping plate; when the first clamping plate and the second clamping plate are clamped together, the first anti-slip protrusions abut against the second anti-slip protrusions.

[0013] Compared to existing technologies, the rotary back clip structure of this utility model is simple in structure and low in production cost. It features a rotatable back clip assembly, improving the flashlight's clamping adaptability and versatility, enabling 360-degree multi-angle clamping and fixed lighting. It also adds a magnetic adsorption function, further expanding its application scenarios and offering high flexibility. The first clamping plate has multiple first anti-slip protrusions on the side near the second clamping plate, and the second clamping plate has multiple second anti-slip protrusions on the side near the first clamping plate. When the first and second clamping plates are clamped, the first and second anti-slip protrusions abut against each other. The anti-slip protrusions significantly increase static friction by "biting" into the surface of the clamped object, such as fabric, webbing, or belt, ensuring the flashlight is firmly clamped even in motion, running, or vibration environments, preventing loosening, displacement, or detachment, and ensuring reliable use.

[0014] In addition, this utility model also provides a flashlight, including the above-mentioned rotating back clip structure. This flashlight also has the same beneficial effects of the above-mentioned rotating back clip structure, which will not be described in detail here. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0024] See Figures 1-5This utility model provides a rotary back clip structure, including a housing 1 and a back clip assembly disposed on one side of the housing 1. The back clip assembly includes a first clamping plate 2 and a second clamping plate 3. A rotary connector 4 connects the first clamping plate 2 to the housing 1, allowing the first clamping plate 2 to rotate 360 ​​degrees relative to the housing 1 via the rotary connector 4. The second clamping plate 3 is hinged to the side of the first clamping plate 2 away from the housing 1. A hinge shaft 40 connects the first clamping plate 2 and the second clamping plate 3, and a torsion spring (not shown in the figure) is sleeved on the hinge shaft 40. The two elastic support legs of the torsion spring are... The first clamp 2 and the second clamp 3 are not pressed against each other to provide clamping force between them. The first clamp 2 and the second clamp 3 are clamped together by the elastic force of the torsion spring. A magnet 5 is provided on the side of the second clamp 3 away from the first clamp 2. The rotating back clip structure of this utility model has a simple structure and low production cost. The rotating back clip assembly improves the flashlight's clamping adaptability and scene versatility, and realizes 360-degree multi-angle clamping and fixing of lighting. It also adds a magnetic adsorption function, further expanding the application scenarios and making it highly flexible in use.

[0025] See Figure 2 and Figure 3 The magnet 5 is embedded in the second clamping plate 3. The second clamping plate 3 is provided with a mounting groove 301 for mounting the magnet 5. The magnet 5 is recessed or flush with the groove opening of the mounting groove 301. By embedding the magnet in the mounting groove and making its surface not protrude, the magnet can be prevented from falling off or being damaged by direct scratching or collision, which greatly enhances the reliability and durability of the structure.

[0026] See Figures 1-3 When the first clamping plate 2 rotates relative to the housing 1, it has a first axis of rotation, which is the axis of the rotating connector 4. When the second clamping plate 3 rotates relative to the first clamping plate 2, it has a second axis of rotation, which is the axis of the hinge shaft 40. The first axis of rotation and the second axis of rotation are perpendicular or nearly perpendicular. This orthogonal axis design ensures that the rotation and clamping functions of the clamping plate assembly do not interfere with each other, making it flexible to use. The rotating connector 4 is a rivet. The first clamping plate 2 is provided with a groove 202 for installing the rivet head. The groove 202 provides a precise receiving space for the head of the rotating connector (rivet), ensuring that the rivet can be correctly connected to the housing. It plays a positioning and limiting role, ensuring that the rivet axis is in the position required by the design and will not be skewed, thereby making the rotation smooth and stable.

[0027] See Figure 1 and Figure 2The second clamping plate 3 is provided with a hook hole 302; the hook hole 302 can expand the suspension function: the hole allows users to insert rope, ring, hook or cable tie, transforming the flashlight from traditional clamping use to hanging lighting, greatly expanding its application scenarios for lighting in fixed positions; it can also provide secondary safety: when using magnetic adsorption or back clip to hold it in a high or dangerous position, a hanging rope can be passed through and tied to the user's wrist or fixed object to prevent the flashlight from accidentally falling and being lost or damaged.

[0028] See Figures 1-4 The second clamping plate 3 has a first thickened block 31 at the pressing end, and the magnet 5 is embedded in the first thickened block 31. The first thickened block significantly enhances the structural strength and thickness of the pressing end, making it less prone to deformation under frequent thumb pressure and extending its service life. At the same time, the extra volume generated by the first thickened block 31 provides sufficient material depth for embedding the magnet 5 (which is usually thicker), ensuring that the strength of the second clamping plate 3 is not weakened, and perfectly wrapping the surface of the magnet, achieving a flush or concave protective effect, and preventing the magnet from directly bearing friction and impact. The second clamping plate 3 is far from the first thickened block 31. A second thickening block 32 is provided at one end of the first thickening block 31. A first plane 311 is provided on the first thickening block 31, and a second plane 321 is provided on the second thickening block 32. The first plane 311 and the second plane 321 are flush. By having the two thickening blocks flush, the first plane 311 and the second plane 321 can simultaneously abut against the metal plane when the flashlight is magnetically attached to the metal surface. This ensures that the flashlight can achieve a large area of ​​close contact when it is magnetically attached to the metal surface, thereby generating a stable and reliable magnetic attraction force and avoiding detachment due to wobbling of the fulcrum or uneven contact surface.

[0029] See Figure 4 The housing 1 is provided with a back plate 11, and an included angle A is formed between the back plate 11 and the first plane 311, which is 4°-8°. When the flashlight is attracted to a horizontal metal surface by a magnet, this included angle can make the flashlight housing automatically tilt up or down by a small angle, thereby ensuring that the light spot is better projected onto the lighting area required by the user. In this embodiment, the included angle A is 6°.

[0030] See Figures 3-5 The first clamping plate 2 has multiple first anti-slip protrusions 201 on the side near the second clamping plate 3, and the second clamping plate 3 has multiple second anti-slip protrusions 303 on the side near the first clamping plate 2. When the first clamping plate 2 and the second clamping plate 3 are clamped together, the first anti-slip protrusions 201 and the second anti-slip protrusions 303 abut against each other. The anti-slip protrusions significantly increase the static friction by "biting" into the surface of the clamped object (such as cloth, webbing, belt), so that the flashlight can be firmly clamped even in motion, running or vibration environment, and is not easy to loosen, shift or fall off, and is reliable in use.

[0031] The rotary back clip structure of this utility model is simple in structure and low in production cost. It features a rotatable back clip assembly, improving the flashlight's clamping adaptability and versatility, enabling 360-degree multi-angle clamping and fixed lighting. It also adds a magnetic adsorption function, further expanding its application scenarios and offering high flexibility. The first clamping plate has multiple first anti-slip protrusions on the side near the second clamping plate, and the second clamping plate has multiple second anti-slip protrusions on the side near the first clamping plate. When the first and second clamping plates are clamped, the first and second anti-slip protrusions abut against each other. The anti-slip protrusions significantly increase static friction by "biting" into the surface of the clamped object, such as fabric, webbing, or belt, ensuring the flashlight is firmly clamped even in motion, running, or vibration environments, preventing loosening, displacement, or detachment, and ensuring reliable use.

[0032] In addition, this utility model also provides a flashlight, including the above-mentioned rotating back clip structure. This flashlight also has the same beneficial effects of the above-mentioned rotating back clip structure, which will not be described in detail here.
