However, during the charging process, if the charging device is not placed stably, it will shift, which may cause the alligator clips to separate from the battery. If the charging process is frequently interrupted, the unstable charging process may damage the internal structure of the battery and shorten its lifespan. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-4 Shown: Example

[0030] A battery charging device with a charging protection mechanism includes:

[0031] Body 1;

[0032] Wire 2 is electrically connected to the output terminal of body 1;

[0033] Alligator clip 3 is electrically connected to the end of wire 2 away from body 1;

[0034] The positioning mechanism 4 has multiple adjusting blocks 402 centrally symmetrically mounted on the middle part of the conductor 2. The middle part of the conductor 2 is provided with a limiting component for limiting the movement of the conductor 2, and the bottom of the limiting component is provided with a positioning element for fixing the position of the limiting component.

[0035] It should be noted that the device 1, the wire 2, and the alligator clip 3 are a battery charger of model XR12V12AH. In use, the two alligator clips 3 are clamped onto the two electrodes of the battery to complete the charging. The horizontal longitudinal section of the multiple adjustment blocks 402 is set as a ring, and they are all fixedly connected and sleeved on the outer wall of the wire 2. In use, the position of the limiting component is adjusted by adjusting the adjustment block 402, thereby adjusting the limiting component to the desired position, and the positioning component is used to fix the limiting component to that position.

[0036] Specifically, the limiting components include:

[0037] Restriction block 401 is disposed on one side of the body 1;

[0038] A limiting groove 408 is formed at the bottom of the limiting block 401, and an adjusting block 402 is inserted into the inside of the limiting groove 408;

[0039] A locking element is provided at the bottom of the limiting block 401.

[0040] Specifically, the inner walls on both sides of the limiting groove 408 are symmetrically provided with wire holes 409, and the wire 2 is inserted and connected inside the wire holes 409.

[0041] It should be noted that the horizontal longitudinal section of the adjustment block 402 is set as an annular shape, the diameter of its large circle is larger than the diameter of the conductor 2 section, and the limiting groove 408 is adapted to the adjustment block 402, and the wire hole 409 is adapted to the conductor 2, so that the adjustment block 402 can pass into the interior of the limiting groove 408, and the conductor 2 can pass into the interior of the wire hole 409. By limiting the wire hole 409, the adjustment block 402 cannot pass out of the limiting groove 408 through the wire hole 409. The locking member is used to block the position where the adjustment block 402 enters the limiting groove 408, thereby restricting the adjustment block 402 inside the limiting groove 408.

[0042] Specifically, the locking components include:

[0043] The base 407 is located at the bottom of the limiting block 401. The base 407 is used to limit the moving distance of the adjusting block 402. The positioning element is located at the bottom of the base 407.

[0044] A fixing part is provided at the connection between the limiting block 401 and the base 407. The fixing part is used to fix the position between the limiting block 401 and the base 407.

[0045] The fixing part includes slots 405 symmetrically opened on the front and back of the limiting block 401. A locking block 404 is inserted into the slot 405. A limiting cavity 403 is opened at the bottom of the limiting block 401. An elastic block 406 is fixedly connected to one side of the locking block 404. The elastic block 406 is inserted into the limiting cavity 403. The elastic block 406 is fixedly connected to the top of the base 407.

[0046] It should be noted that the elastic block 406 can be made of plastic, so that the elastic block 406 will deform when squeezed and will recover its deformation after the squeeze is released; the slot 405 is adapted to the slot 404, so that the slot 404 can be inserted into the interior of the slot 405.

[0047] Furthermore, when it is necessary to fix the base 407 and the limiting block 401, first press the locking block 404 against one side of the elastic block 406, causing the elastic block 406 to deform under pressure. Then, insert the elastic block 406 and the locking block 404 into the interior of the limiting cavity 403. After the locking block 404 is in contact with the inner wall of the limiting cavity 403, release the pressing of the locking block 404 and continue to move the position of the locking block 404. When the locking block 404 moves to be aligned with the slot 405, the elastic block 406 restores its deformation and drives the locking block 404 to move into the interior of the slot 405. The blocking of the slot 405 and the locking block 404 fixes the base 407 and the limiting block 401. The blocking of the fixed position base 407 prevents the adjusting block 402 from moving out of the limiting groove 408.

[0048] Example 2: A positioning element applied to the charging device in Example 1;

[0049] The positioning component comprises the aforementioned body 1, wire 2, alligator clip 3, and positioning mechanism 4.

[0050] The positioning component includes double-sided adhesive 5 set at the bottom of the base 407, which is used to fix the position of the base 407.

[0051] It should be noted that when it is necessary to fix the position of the limiting component, first stick the double-sided tape 5 to the bottom of the base 407, then stick the double-sided tape 5 to the desired position, and use the double-sided tape 5 to fix the position of the base 407, thereby fixing the position of the limiting component and preventing the limiting component from moving. After use, peel the double-sided tape 5 off the bottom of the base 407. When using it next time, take out a new double-sided tape 5 and stick it.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
