An installation frame 3 is provided on the outer side of the battery body 1 and can be fixedly mounted on it. A lower pressure frame is movably connected to the installation frame 3 and can move vertically relative to the installation frame 3. A horizontal groove is provided in the middle of the lower pressure frame, and a mounting plate 10 is detachably installed in the groove, allowing the mounting plate 10 to be adjusted according to the user's needs. The mounting plate 10 is set according to requirements, and its position can be adjusted. An electrolyte hydrometer 2 can be installed on the mounting plate 10. With the adjustment of the mounting plate 10, the electrolyte hydrometer 2 can be adjusted. A squeezing mechanism is movably connected to the top of the lower pressure frame. The lower pressure frame can move vertically relative to the squeezing mechanism. The top of the squeezing mechanism extends out of the top of the lower pressure frame, and the bottom of the squeezing mechanism can contact the electrolyte hydrometer 2. Under the squeezing of the squeezing mechanism, the electrolyte hydrometer 2 can squeeze and absorb electrolyte. That is, by pushing and squeezing, multiple electrolytes can be absorbed, making the detection more convenient.

[0023] Please see Figures 1 to 3 One side of the mounting frame 3 is threaded with a bolt 9. One end of the bolt 9 passes through the mounting frame 3 and abuts against the outside of the battery body 1. Under the action of screwing the mounting frame 3, the bolt 9 can limit the mounting frame 3.

[0024] Please see Figures 1 to 3 The lowering frame includes a limiting frame 4 and a mounting frame 5. The limiting frame 4 is a square frame structure with an opening at the top. The middle of the limiting frame 4 passes through the mounting frame 3 and is located below the mounting frame 3. The two ends of the limiting frame 4 are located above the mounting frame 3. The two ends of the two limiting frames 4 are fixed to the two mounting frames 5 respectively, and the mounting frames 5 are parallel to each other, so that the mounting plate 10 can be smoothly installed in the slide groove, and the limiting frame 4 and the mounting frame 5 can be linked relative to each other.

[0025] Please see Figures 1 to 3 The mounting frame 5 is square in shape, and the sliding groove is opened at the bottom of the inner side of the mounting frame 5. The top of the middle of the limiting frame 4 is fixedly connected to the second spring 12. The top of the second spring 12 is fixed to the bottom of the mounting frame 3. Under the action of the tension of the second spring 12, it can automatically return to its position, which is convenient for the next test and the observation after the electrolyte hydrometer 2 absorbs the electrolyte.

[0026] Please see Figures 1 to 4The electrolyte hydrometer 2 includes a balloon 13 and a limiting plate 14. The balloon 13 is located at the top of the mounting plate 10.

One end of the baffle 16 can extend out of the mounting plate 10 and abut against the inner wall of the slide groove, thereby assisting in the limitation of the mounting plate 10, so that the mounting plate 10 can be relatively stably placed in the slide groove. The other end of the baffle 16 is inside the mounting plate 10 and is fixedly connected to a third spring 17. One end of the third spring 17 is fixed to the mounting plate 10. Under the action of the elastic force of the third spring 17, the baffle 16 can abut against the slide groove and close the mounting opening 15. The baffle 16 has an opening that can coincide with the mounting opening 15, so that the limiting plate 14 can be smoothly installed in the slide cavity.

[0028] Please see Figures 1 to 3 The compression mechanism includes a compression press frame 6 and a compression plate 8. The compression press frame 6 is a square frame structure with an opening at the bottom. The middle of the compression press frame 6 is located at the top of the mounting frame 5, and the two ends of the compression press frame 6 are located inside the frame structure of the mounting frame 5. The two ends of the two compression press frames 6 are fixedly connected to the compression plate 8. The compression plate 8 is located directly above the balloon 13. Under the push of the compression press frame 6, the compression plate 8 can move down smoothly to compress the balloon 13.

[0029] Please see Figures 1 to 3 The top of the frame structure of the mounting bracket 5 is fixedly connected to a square frame structure finger holder 7 with an opening at the top. The finger holder 7 is located between the squeezing and pressing brackets 6, allowing the finger to pass smoothly between the finger holder 7 and the mounting bracket 5. When moving downwards, the finger holder 7 can push the mounting bracket 5 to move. The bottom of the middle of the squeezing and pressing bracket 6 is fixedly connected to a first spring 11. The bottom end of the first spring 11 is fixed to the top of the mounting bracket 5. Under the action of the elastic force of the first spring 11, the squeezing and pressing bracket 6 can return to its original position smoothly, so that the electrolyte hydrometer 2 can smoothly absorb liquid.

[0030] In summary, this automatic liquid aspiration device for detecting battery electrolyte concentration involves, during use, fitting the mounting frame 3 onto the battery body 1, then tightening the bolts 9 to ensure it abuts against the battery body 1, thus securing the mounting frame 3. Next, pressing the baffle 16 aligns the opening with the mounting port 15. Then, installing the limiting plate 14 within the sliding cavity, and finally inserting the mounting cross plate 10 into the sliding groove, allows the baffle 16 to close the mounting port 15 under the force of the third spring 17, and the baffle 16 abuts against the inner wall of the sliding groove, assisting in the installation... Position the horizontal plate 10, then pass your fingers between the finger sleeve 7 and the mounting bracket 5, place your thumb on the top of the middle of the squeezing and pressing bracket 6, and push the mounting bracket 5 downward so that the electrolyte hydrometer 2 can be inserted into the battery body 1 through the electrolyte port. Then squeeze the squeezing and pressing bracket 6 so that the squeezing and pressing bracket 6 can move relative to the mounting bracket 5. Under the push of the squeezing and pressing bracket 6, the squeezing plate 8 can be moved down, and then the balloon 13 can be squeezed so that the electrolyte hydrometer 2 can be inserted into the battery body 1 to extract the electrolyte.
