Description

Technical Field

[0001] This utility model relates to the field of flashlight technology, and in particular to a waterproof rechargeable flashlight. Background Technology

[0002] Most rechargeable flashlights on the market currently have the charging port located on the body or back cover. Due to dust and water resistance requirements, such as for outdoor use in rainy weather, a sealing plug is usually placed on the charging port. When not charging, the plug is used to seal the charging port; when charging is needed, the plug is pulled out and the charging connector is inserted. However, the sealing plug is usually made of silicone or soft rubber, which is prone to breakage over time. Furthermore, the plug is typically small, making pulling it out and putting it on inconvenient, especially in low light conditions. To address this, a rotating cap sealing structure has been designed. The rotating cap has a through-hole. When rotated until the through-hole is misaligned with the charging port, the tight fit between the rotating cap and the body seals the charging port, achieving a seal. When rotated until the through-hole aligns with the charging port, the seal is broken, and charging can then begin. However, current rotating cap sealing structures typically rely solely on the pressure of the tube body against the rotating cap to seal the charging port. To ensure smooth rotation, the cap and tube body cannot be too tightly fitted; otherwise, the cap becomes difficult to rotate, resulting in a less than ideal seal. Furthermore, the cap is prone to rotation under external force, potentially opening the charging port accidentally. Sometimes, the cap is only partially rotated, failing to completely cover the charging port. Additionally, current rotating caps are usually circular, resulting in a larger contact area with the tube body and greater friction, making rotation more difficult. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a waterproof charging interface flashlight with a more reasonable structural design that achieves a good sealing and waterproof effect while ensuring easier rotation of the rotating cover and more convenient operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a waterproof flashlight with a sealed charging interface, comprising a main body of the flashlight, the main body including a barrel and a charging interface, a mounting groove provided on the barrel, the charging interface being exposed in the mounting groove; a rotating cover installed in the mounting groove, the rotating cover being rotated to align with the charging interface to form a sealed waterproof structure; a fixing part is provided on the bottom surface of the mounting groove, the fixing part extending into the barrel; the rotating cover is movably installed in the mounting groove by a locking limit screw to form a rotatable structure, the limit screw being tightened in the fixing part; a spring is provided in the fixing part, the spring being connected to the rotating cover to form a tensioning structure for the rotating cover; a locking structure with a convex-concave fit is provided on the bottom surface of the rotating cover, when the rotating cover is rotated to cover the charging interface, the spring tightens the rotating cover so that the convex-concave parts of the locking structure interlock to achieve the rotating cover being tightly attached to the surface of the mounting groove.

[0005] Furthermore, the locking structure with a convex-concave fit includes locking teeth and locking sleeve. The locking teeth are disposed on the bottom surface of the rotating cover, and the locking sleeve is installed in the fixing part. The opposite end faces of the locking teeth and the locking sleeve are provided with matching tooth-like structures. When the rotating cover is pulled up, the locking teeth and the locking sleeve disengage from each other. When the rotating cover is released, the locking teeth and the locking sleeve engage with each other to tighten the rotating cover.

[0006] Furthermore, the toothed structure includes arc-shaped teeth respectively disposed on the bottom end face of the locking tooth portion and arc-shaped teeth disposed on the top end face of the locking sleeve, the arc-shaped teeth of both having the same curvature so that the locking tooth portion and the locking sleeve form a seamless connection.

[0007] Furthermore, the end of the limiting screw has a threaded head, which is tightened in the fixing part to lock the entire limiting screw. The rotating cover, locking teeth, spring and locking sleeve are together fitted on the main body of the limiting screw.

[0008] Furthermore, the spring passes through the locking sleeve and locking teeth and is connected and fixed to the rotating cover.

[0009] Furthermore, the rotating cover has a dumbbell-shaped structure that is wide at both ends and narrow in the middle. The middle parts of both sides of the rotating cover are concave in an arc shape towards the rotation center of the rotating cover, and the wide parts at both ends of the rotating cover are larger than the size of the charging interface, so as to completely cover the charging interface while reducing the contact area.

[0010] Furthermore, the charging interface is fixed on a mounting base, which is secured to the mounting part by fixing screws.

[0011] Preferably, the charging interface is a waterproof TYPE-C interface or MICRO-USB interface, and a sealing ring is provided around the charging interface.

[0012] This invention uses a limiting screw, spring, and toothed locking structure to fix the rotating cover, allowing it to fit tightly against the surface of the charging port's mounting groove under the action of the spring, thus achieving a good sealing and waterproof effect for the charging interface. Simultaneously, the spring's elasticity allows the rotating cover to be pulled up, enabling smoother rotation. Furthermore, the rotating cover employs a non-circular structure with recessed sides, resulting in a smaller area than a complete circular cover. This reduces the contact area with the mounting groove, decreasing friction and further improving the smoothness of rotation. Attached Figure Description

Detailed Implementation

[0018] In this embodiment, refer to Figures 1-4 The waterproof flashlight with a sealed charging interface includes a main body, comprising a tube body 1 and a charging interface 2. The tube body 1 has a mounting groove 11, with the charging interface 2 exposed within it. A rotating cover 3 is installed in the mounting groove 11, forming a sealed waterproof structure by rotating the rotating cover 3 to align with the charging interface 2. A fixing part 12 is provided on the bottom surface of the mounting groove 11, extending into the tube body 1. The rotating cover 3 is movably installed in the mounting groove 11 by a locking limit screw 4, forming a rotatable structure. The limit screw 4 is tightened in the fixing part 12. A spring 5 is provided in the fixing part 12, connected to the rotating cover 3 to form a tensioning structure. A locking structure with a convex-concave fit is provided on the bottom surface of the rotating cover 3. When the rotating cover 3 rotates to cover the charging interface 2, the spring 5 tightens the rotating cover 3, causing the convex and concave parts of the locking structure to interlock, ensuring the rotating cover 3 is tightly against the surface of the mounting groove 11, thus sealing the charging interface 2.

[0019] The locking structure with a convex-concave fit includes a locking tooth 31 and a locking sleeve 6. The locking tooth 31 is disposed on the bottom surface of the rotating cover 3, and the two are an integral structure. The locking sleeve 6 is installed in the fixing part 12. The opposite end faces of the locking tooth 31 and the locking sleeve 6 are provided with matching tooth-like structures. When the rotating cover 3 is pulled up, the locking tooth 31 and the locking sleeve 6 disengage from each other. When the rotating cover 3 is released, the rotating cover 3 is tightened under the pulling force of the spring 5 so that the locking tooth 31 and the locking sleeve 6 are engaged with each other.

[0020] Spring 5 passes through locking sleeve 6 and locking teeth 31 and is connected and fixed to rotating cover 3, generating a pulling force on rotating cover 3. The toothed structure includes arc-shaped teeth respectively provided on the bottom end face of locking teeth 31 and arc-shaped teeth provided on the top end face of locking sleeve 6. The arc-shaped teeth of both have the same curvature to make locking teeth 31 and locking sleeve 6 form a seamless connection. This structure has two functions: First, when rotating cover 3 is pushed by external force, it will tend to rotate. However, since locking teeth 31 and locking sleeve 6 are interlocked, it is difficult for locking teeth 31 to rotate relative to locking sleeve 6 without pulling up rotating cover 3, thus ensuring that rotating cover 3 is not easily pushed to open charging interface 2. Second, when rotating rotating cover 3 to close charging interface 2, sometimes the charging interface 2 may not be completely closed. At this time, due to the action of spring 5, locking teeth 31 is fully interlocked with locking sleeve 6, actively pushing rotating cover 3 to rotate until it just completely covers charging interface 2, thus solving the problem of accidental cover leakage.

[0021] The end of the limiting screw 4 has a threaded head 41, which is tightened in the fixing part 12 to lock the entire limiting screw 4. The rotating cover 3, the locking teeth 31, the spring 5, and the locking sleeve 6 are together fitted on the main body of the limiting screw 4.

[0022] The rotating cover 3 is a dumbbell-shaped structure that is wide at both ends and narrow in the middle. The middle parts of both sides of the rotating cover 3 are concave in an arc shape towards the rotation center of the rotating cover 3, and the wide parts at both ends of the rotating cover 3 are larger than the size of the charging interface 2, so as to completely cover the charging interface 2 while reducing the contact area.

[0023] The charging interface 2 is fixed on a fixed base 7, which is locked to the fixed part 12 by a fixing screw 8.

[0024] The charging port 2 uses a waterproof TYPE-C interface (or MICRO-USB interface), and a sealing ring is provided around the charging port 2, which can be used with the rotating cover 2 to achieve an IPX67 waterproof rating.

[0025] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
