[0002] A storage battery generally refers to the general term of all chemical energy batteries that can be recharged and reused after the power is used to a certain extent. When the storage battery is in use, electrolyte needs to be injected into it. After long-term use, the liquid level of the electrolyte inside the storage battery will drop, and it is necessary to regularly supplement electrolyzed water to the storage battery. Usually, a liquid injection valve is used for liquid injection. The existing liquid injection valve is a component used for regularly injecting electrolyte into the storage battery. When in use, the liquid injection valve is directly fixed and installed by rotating its external thread installation structure with the internal thread structure inside the storage battery, and the fixed installation is strengthened during installation to improve the enhanced stability of the liquid injection valve installed on the storage battery;

Two tooth reinforcement clamping heads 1021 are arranged on one side of the moving plate 1023. Until the moving plate 1023 is moved to drive the tooth reinforcement clamping heads 1021 to move and squeeze and fix on the surface of the internal thread structure of the storage battery for reinforcement. An elastic block 1024 is arranged at the connection between the rear surface of the moving plate 1023 and the inner surface of the moving groove 1022. At the same time, when clamping, the elastic block 1024 is used to strengthen the elastic fastening of the moving plate 1023 and the tooth reinforcement clamping heads 1021 again.

When the moving plate 1023 is moved, the limiting block 1026 is driven to slide limit inside the limiting groove 1025 to facilitate stable movement adjustment.

[0027] In order to facilitate the moving and strengthening installation of the moving plate 1023 and the tooth reinforcement clamping heads 1021 through the screw-in adjustment component. In this embodiment, preferably, the screw-in adjustment component includes a threaded pull rod 1027 arranged on one side at the top end of the moving groove 1022. One end of the threaded pull rod 1027 is fixed to the end of the moving plate 1023 through a fixing screw. A nut 1028 is rotated on the surface of the other end of the threaded pull rod 1027. When the nut 1028 is rotated at the end of the threaded pull rod 1027, the threaded pull rod 1027 is driven to move. The threaded pull rod 1027 moves to drive the moving plate 1023 and the tooth reinforcement clamping heads 1021 to move and strengthen the installation.

[0028] Buffer protection mechanism, and the buffer protection mechanism includes a buffer protection component arranged on the outer surface of the main valve body 101. A fixed installation component is arranged at the bottom edge of the buffer protection component.

[0029] In order to facilitate the buffer protection of the top of the main valve body 101 and the surface of the bolt head 105 through the buffer protection component, in this embodiment, preferably, the buffer protection component includes a closed groove 1014 opened on the outer surface of the main valve body 101. An installation cover 1013 is arranged inside the closed groove 1014. An outer elastic rubber protection cover 1011 is arranged on the surface of the installation cover 1013. After closing the installation cover 1013 through the closed groove 1014, the outer elastic rubber protection cover 1011 is fixed. An outer rubber protection ring 1012 is fixed to the top of the bolt head 105 through a fixing screw. Fixing the outer rubber protection ring 1012 to the top of the bolt head 105 again facilitates the buffer protection of the top and rear end of the liquid injection valve body 100 by the outer elastic rubber protection cover 1011 and the outer rubber protection ring 1012.

[0030] In order to facilitate the fixed installation and protection of the installation cover 1013 and the outer elastic rubber protection cover 1011 through the fixed installation component, in this embodiment, preferably, the fixed installation component includes an installation screw 1015 arranged at the bottom edge of the installation cover 1013. An internal thread hole 1016 is opened at the bottom edge inside the closed groove 1014. The end of the installation screw 1015 matches the internal structure of the internal thread hole 1016. After closing the installation cover 1013 on the outer surface of the outer elastic rubber protection cover 1011, rotate the installation screw 1015 to embed it into the internal thread hole 1016 to fixedly install and buffer-protect the installation cover 1013 and the outer elastic rubber protection cover 1011.

After installation, inject liquid through the liquid injection port 103 and then enter the inside of the main valve body 101. Then, inject electrolyte into the battery through the liquid inlet, and it is convenient to use the liquid injection valve body 100 to inject electrolyte into the battery.

[0032] Then, when the liquid injection valve body 100 is rotationally fixed on the storage battery through the external thread mounting structure 102 for use, rotate the nut 1028 at the end of the threaded pull rod 1027 again to drive the threaded pull rod 1027 to move. When the threaded pull rod 1027 moves, it drives the moving plate 1023 to move. The bottom end of the moving plate 1023 drives the limiting block 1026 to slide limitally inside the limiting groove 1025, so as to stably move the moving plate 1023 to drive the tooth reinforcement chuck 1021 to move and squeeze and bite on the surface of the internal thread structure installed on the storage battery. Again, the elastic block 1024 strengthens the elastic pressing and fixing of the moving plate 1023 and the elastic block 1024, so as to strengthen the fixed installation after the liquid injection valve body 100 is installed. When the storage battery installation device vibrates during use, it is not easy to cause the liquid injection valve body 100 to have slight rotational loosening, the installation and use are more stable, and the enhanced stability of the liquid injection valve body 100 installed on the storage battery is improved;

[0033] Finally, before the liquid injection valve body 100 is installed and used, close the installation cover 1013 inside the closing groove 1014 so that the outer elastic rubber cover 1011 is on the outer surface of the main valve body 101. Rotate the installation screw 1015 and embed it into the internal thread hole 1016 to fix the outer elastic rubber cover 1011 and the installation cover 1013. Again, fix the outer rubber guard ring 1012 on the surface of the bolt head 105. When the top of the liquid injection valve body 100 is exposed to the outside when installed on the storage battery, when it is impacted at the top of the main valve body 101, it directly impacts on the surfaces of the outer elastic rubber cover 1011 and the outer rubber guard ring 1012, and the outer elastic rubber cover 1011 and the outer rubber guard ring 1012 deform to buffer the impacted object, reduce the impact, and are not easy to cause impact damage, improve the buffer protection effect of the liquid injection valve body 100 installed on the storage battery, and extend the service life.
