Embodiment 2

[0020] Embodiment 2: Compared with Embodiment 1, the difference lies in that the sealing parts of the sealing device are different, and the rest are the same.

[0021] see image 3 and Figure 4 , The liquid injection hole sealing device includes the ring-shaped No. 2 handle 101, and the inside of the No. 2 handle 101 is provided with rubber teeth, which can increase the friction with the hand and prevent the device from being damaged due to accidental slipping when the device is in use. The No. 2 handle 101 is provided with a No. 4 through hole 102 .

[0022] No. 3 connecting rods 103 and No. 4 connecting rods 104 are respectively fixed on the inner sides of the two ends of the No. 2 handle 101, and rubber layers are arranged on the outsides of the No. 3 connecting rods 103 and No. 4 connecting rods 104, which can strengthen the connection between the device and The sealing effect between the liquid injection holes prevents liquid leakage.

[0023] The No. 3 flexible part ...

Abstract

The invention belongs to a sealing device for a liquid filling port. The sealing device for the liquid filling port comprises a ring-shaped handle; a first connecting rod and a second connecting rod are respectively fixed on the inner sides of the end parts of the two ends of the handle; the end part of the other end of the first connecting rod and the other end part of the other end of the second connecting rod are matched to fixedly connect a soft ball; a first flexible piece is hinged to the inner side of the first connecting rod; a second flexible piece is hinged to the inner side of the second connecting rod; the first flexible piece and the second flexible piece are connected with each other through a first ball; a first flexible piece hinged point, a second flexible piece hinge point and the first ball are triangular; a pull rod is fixed with the first ball and is used for manual operation. The sealing device has a reasonable structure, and is good in sealing effect.

Description

technical field [0001] The invention belongs to a liquid injection hole sealing device. Background technique [0002] The top of the commonly used battery is equipped with a liquid injection hole. During the production and use of the battery, it is necessary to fill the battery electrolyte into the battery box. The liquid injection system passes through the liquid injection head and the liquid injection hole on the battery cover. Docking to achieve fluid injection. After liquid injection, the battery box needs to be sealed. If it is not sealed, not only will the liquid leak, but also the electrolyte is corrosive to a certain extent, which will cause unnecessary harm to the human body. The existing equipment has the defects of unreasonable structure in the sealing process, which causes lax airtightness and inconvenient operation, which affects the quality and service life of the storage battery. For example, the liquid injection hole of some lead-acid battery covers is gene...
