[0039] The gas injection mechanism 4 is used to continuously inject air into the lead-acid battery body 101 by manual traction; the gas injection mechanism 4 includes a gas cylinder 401, a gas hole 402, a connecting frame 403 and a sealing sheet 405;

[0042] Among them, one end of the one-way valve 202 is connected to the middle of the outer wall of the connecting pipe 201, the gas delivery pipe 203 is connected between the one-way valve 202 and the gas cylinder 401, the barometer 206 is installed on the outer wall of the connecting pipe 201, the outer wall of the inner sleeve 204 is slidably connected to the bottom of the inner wall of the connecting pipe 201, one end of the rubber sealing ring 205 is fixedly connected to the bottom of the connecting pipe 201, and the other end of the rubber sealing ring 205 is fixedly connected to the bottom of the outer wall of the inner sleeve 204;

[0043] Air is injected into the interior of the connecting tube 201 through the air cylinder 401 in cooperation with the one-way valve 202, and the one-way valve 202 is provided to prevent air backflow. The rubber sealing ring 205 is squeezed by the inner ring 204 to deform it, so that the deformed rubber sealing ring 205 can be used to seal between the connecting tube 201 and the electrolyte injection port 102.

[0044] In one embodiment, the driving mechanism 3 includes a driving handle 301, a traction rope 302, a piston plate 303, a bottom pad 304, a first spring 305, a traction pad 306 and a second spring 307;

[0045] The driving handle 301 is arranged at the top of the connecting tube 201, one end of the traction rope 302 is fixedly connected to the bottom of the driving handle 301, the other end of the traction rope 302 passes through the inner wall of the connecting tube 201 and is fixedly connected to the upper surface of the bottom pad 304, the outer wall of the bottom pad 304 is slidably connected to the inner wall of the connecting tube 201, the traction pad 306 is fixedly connected to the top of the inner ring 204, the outer wall of the traction pad 306 is slidably connected to the inner wall of the connecting tube 201, the first spring 305 is fixedly connected between the bottom pad 304 and the traction pad 306, one end of the second spring 307 is fixedly connected to the inner wall of the connecting tube 201, the other end of the second spring 307 is fixedly connected to the upper surface of the traction pad 306, the top of the connecting tube 201 is fixedly connected with the connecting seat 52, and the bottom of the driving handle 301 is hinged to the inner wall of the connecting seat 52 through a damping shaft;

[0046] By moving the driving handle 301 to rotate in the connecting seat 52, the moving driving handle 301 drives the traction rope 302 to move, and the moving traction rope 302 drives the piston plate 303 and the bottom pad 304 to move. The moving piston plate 303 slides in the connecting tube 201 to ensure the sealing between the connecting tube 201 and the traction rope 302. The moving bottom pad 304 drives the first spring 305 to be initially compressed. When the first spring 305 is initially compressed, it drives the traction pad 306 to move under the action of force, and the moving traction pad 306 drives the second spring 307 and the inner ring 204 to move.

[0047] In one embodiment, the gas injection mechanism 4 further includes a traction handle 404 and a third spring 406;

[0048] One end of the traction handle 404 is fixedly connected to one end of the connecting frame 403, the outer wall of the traction handle 404 is slidably connected to the inner wall of the gas cylinder 401 through a sealing ring, one end of the third spring 406 is fixedly connected to one side of the connecting frame 403, the other end of the third spring 406 is fixedly connected to the inner wall of the gas cylinder 401, and one side of the outer wall of the gas cylinder 401 is fixedly connected with a handle 51;

[0049] By holding the handle 51 and pulling the traction handle 404 to move, the moving traction handle 404 drives the sealing plate 405 and the third spring 406 to move. The moving sealing plate 405 presses the air on one side of the air cylinder 401 into the connecting pipe 201 and the interior of the lead-acid battery body 101 through the air supply pipe 203 and the one-way valve 202, and the moving third spring 406 is compressed.

[0050] When the utility model is working: first, the connecting tube 201 is moved to drive the inner sleeve 204 to be inserted into the electrolyte injection port 102, and then the threaded sleeve 103 is rotated to connect with the electrolyte injection port 102 by means of threads, so that the connecting tube 201 is fixed on the electrolyte injection port 102 as a whole.

[0051] After the connecting tube 201 is fixed as a whole, the driving handle 301 is moved to rotate in the connecting seat 52, and the moving driving handle 301 drives the traction rope 302 to move, and the moving traction rope 302 drives the piston plate 303 and the bottom pad 304 to move. The moving piston plate 303 slides in the connecting tube 201 to ensure the sealing between the connecting tube 201 and the traction rope 302, and the moving bottom pad 304 drives the first spring 305 to be initially compressed; when the first spring 305 is initially compressed, it drives the traction pad 306 to move under the action of force, and the moving traction pad 306 drives the second spring 307 and the inner ring 204 to move, and the moving second spring 307 is compressed, and the moving inner ring 204 squeezes the rubber sealing ring 205 to deform it, so as to seal the connecting tube 201 and the electrolyte injection port 102. When the movement of the inner ring 204 is blocked and the traction pad 306 cannot continue to move, the first spring 305 is further compressed through the bottom pad 304, so that the driving handle 301 can be smoothly rotated about 90°, preventing the driving handle 301 from resetting during the detection process due to insufficient rotation angle.

[0052] When the connection pipe 201 and the electrolyte injection port 102 are sealed, the handle 51 is held and the traction handle 404 is pulled to move. The moving traction handle 404 uses the traction handle 404 to drive the sealing sheet 405 and the third spring 406 to move. The moving sealing sheet 405 presses the air on one side of the air cylinder 401 into the connection pipe 201 and the lead-acid battery body 101 through the air delivery pipe 203 and the one-way valve 202, and the moving third spring 406 is compressed. When the traction handle 404 moves to the limit, the connection frame 403 is driven to move in the opposite direction through the compressed third spring 406, so that the sealing sheet 405 is deformed under the action of negative pressure so that The air on the side of the connecting frame 403 in the air cylinder 401 away from the traction handle 404 is sucked into the side close to the traction handle 404, so that the air can be continuously injected into the connecting tube 201 and the lead-acid battery body 101 by repeatedly pulling the traction handle 404, and the outside air can smoothly enter the air cylinder 401 through the arranged air holes 402 for air replenishment, and then the air pressure in the connecting tube 201 and the lead-acid battery body 101 is detected by the barometer 206. When the air pressure displayed by the barometer 206 reaches the sealing detection requirement, stop pulling the traction handle 404, and then the sealing of the lead-acid battery can be judged by observing the change of the air pressure displayed by the barometer 206.

[0053] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
