DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a portable LED lamp with replaceable batteries, including an LED flashlight body 1, a battery slot 2 is provided on the top of the LED flashlight body 1, a battery 3 is installed in the battery slot 2, a rubber ring 4 is bonded to the top of the LED flashlight body 1, an internal thread ring 5 is screwed on the upper side of the outer wall of the LED flashlight body 1, a rotating cover 6 is integrally formed on the top of the internal thread ring 5, a pressing plate groove 7 is provided at the bottom of the rotating cover 6, a pressing plate 8 is provided in the pressing plate groove 7, and a limiter 9 is provided on both the left and right sides of the bottom of the pressing plate 8, the limiter 9 is connected to the top of the LED flashlight body 1, and the bottom of the pressing plate 8 is tightly fitted on the top of the rubber ring 4;

[0020] The limiting member 9 is used to limit the moving track of the pressing plate 8 so that the pressing plate 8 can only move up and down.

[0021] Conventional flashlights are also provided with a rotating cover, which can be directly rotated to make its bottom rotate and press against the rubber ring. The rotating contact with the rubber ring can easily cause wrinkles or even wear on the surface of the rubber ring, affecting the sealing effect.

[0022] A pressing block 10 is installed at the bottom of the pressing plate groove 7 , and the bottom of the pressing block 10 is attached to the top of the battery 3 .

[0023] Specifically, the limiting member 9 includes a limiting rod 11, the top of which is fixedly mounted on the bottom of the pressure plate 8, limiting slots 12 are provided on both sides of the top of the LED flashlight body 1, and the rubber ring 4 is provided with a through hole body matching the position of the limiting slot 12, the bottom end of the limiting rod 11 passes through the through hole body on the rubber ring 4 and is inserted into the limiting slot 12, and the side wall of the limiting rod 11 fits and slides relative to the inner wall of the limiting slot 12.

[0024] Specifically, the bottom end height of the limiting plug rod 11 is lower than the bottom height of the internal thread ring 5 .

[0025] like Figure 3 As shown, by making the bottom end height of the limiting rod 11 lower than the bottom height of the internal threaded ring 5, when the internal threaded ring 5 is not screwed onto the outer wall of the LED flashlight body 1, the bottom end of the limiting rod 11 has been inserted into the limiting slot 12 to first play a limiting role.

[0026] Specifically, a circular groove 13 is provided in the middle of the top wall of the pressure plate groove 7, and a bearing 14 is provided in the circular groove 13. The outer wall of the outer ring of the bearing 14 is fixedly installed on the inner wall of the circular groove 13, and a connecting column 15 is fixedly installed on the bottom end of the inner ring of the bearing 14. The bottom end of the connecting column 15 is fixedly installed in the middle of the top of the pressure plate 8.

[0027] By providing a bearing 14 and a connecting column 15 to connect the pressing plate 8 and the rotating cover 6, the pressing plate 8 and the rotating cover 6 can be integrated to prevent the pressing plate 8 from falling off from the pressing plate groove 7 when the rotating cover 6 is not installed on the LED flashlight body 1, and the rotating cover 6 and the pressing plate 8 can rotate relative to each other through the bearing 14.

[0028] Specifically, the side walls of the pressing plate 8 do not contact the inner side walls of the pressing plate groove 7 , and the top of the pressing plate 8 does not contact the top wall of the pressing plate groove 7 .

[0029] By ensuring that the side walls of the pressing plate 8 do not contact the inner side walls of the pressing plate groove 7 and the top of the pressing plate 8 does not contact the top wall of the pressing plate groove 7, it is possible to avoid large friction caused by the pressing plate 8 contacting the inside of the pressing plate groove 7 when the rotary cover 6 rotates.

[0030] Specifically, the pressing block 10 includes a block body 16, the top of the block body 16 does not contact the bottom of the pressing plate 8, mounting grooves 17 are provided on the left and right sides of the top of the block body 16, a spring 18 is fixedly installed on the inner bottom wall of the mounting groove 17, the top of the spring 18 is fixedly installed on the bottom of the pressing plate 8, and the bottom of the block body 16 is tightly fitted on the top of the battery 3.

[0031] Figure 4 The spring 18 shown is in a compressed state, and the bottom of the block 10 can be pressed against the battery 3 by the compression elasticity of the spring 18 to fix the battery 3 again.

[0032] By dividing the pressing block 10 into a block body 16 and a spring 18 , if the pressing block is directly pressed hard on the battery 3 , it is easy to cause damage to the battery 3 . The spring 18 can change the hard contact into a flexible pressing contact.

[0033] Working principle: When replacing the battery 3, the rotating cover 6 can be rotated to make the internal thread ring 5 detach from the LED flashlight body 1, and at the same time, the pressing block 10 detaches from the battery 3, and then the battery 3 in the battery slot 2 is replaced. Then, when installing the rotating cover 6, the bottom end of the limiting rod 11 is first inserted into the limiting slot 12, and the internal thread ring 5 is screwed onto the LED flashlight body 1 again, so that the bottom of the pressing plate 8 is pressed tightly against the rubber ring 4.
