Description
Technical Field
The utility model relates to the technical field of air tightness detection devices, in particular to the technical field of air tightness detection devices for rivets.
Background
The lithium ion battery has the advantages of high energy density and power density, light weight, small volume, good safety, environmental protection and the like, is widely applied to the fields of mobile phones, digital cameras and the like, and is also applied to the fields of various electric tools, and along with the strong support of the state to new energy automobiles, the lithium ion battery also brings great opportunity for development in the field of electric automobiles, and among various lithium ion batteries, a cylindrical aluminum shell lithium ion battery is paid attention to due to the advantages of high energy density, good safety performance and the like.
After the liquid injection of the cylindrical aluminum shell lithium ion battery with the full tab is completed, the liquid injection hole on the cover plate needs to be plugged. The better plugging device used at present is a rivet, and the rivet shell and the rivet head of the rivet core are plugged at the liquid injection hole of the cover plate in a riveting mode. Not only can realize better shutoff effect, but also can play the fixed effect of connection to collecting tray and apron. However, such plugging devices currently do not have an effective and rapid detection device for detecting the sealing effect after plugging.
Disclosure of Invention
The utility model provides an air tightness detection tool for an all-aluminum external locking rivet for a battery, which aims to solve the defects. The sealing device can be used for effectively and rapidly detecting the air tightness of the sealing effect of the all-aluminum external locking rivet for the battery after the use, and is very convenient to use.
The technical solution adopted by the utility model for solving the technical problems is as follows:
the utility model provides a gas tightness detects frock with outer lock rivet of full aluminium, it mainly comprises main part, air cock and base, set up corresponding upper through-hole and lower through-hole in the main part, be provided with the internal thread in this upper through-hole, set up the upper air hole in the air cock, be provided with the external screw thread in the outside of this air cock, the air cock is installed in the internal thread department of through-hole in the main part through its external screw thread spiral, set up the lower gas hole corresponding with the upper air hole of air cock on the base, base movable mounting is in the lower through-hole department of main part.
Preferably, a boss is arranged at the lower end of the base, and the base is movably arranged at the lower through hole of the main body through the boss.
Preferably, an upper sealing ring is arranged on the lower end face of the air tap.
Preferably, the upper end face of the base is provided with a lower sealing ring.
Preferably, the main body is integrally C-shaped.
The beneficial effects achieved by adopting the technical proposal of the utility model are as follows: when the gas-liquid detecting tool is used, a plugged battery is placed on the base, the gas nozzle is rotated, the gas nozzle and the base are utilized to tightly clamp the current collecting disc and the cover plate of the battery required detecting part, then, gas with certain pressure is injected into the gas nozzle, finally, the detecting tool is placed in liquid, if gas is emitted from the bottom of the main body, the gas tightness is not met, otherwise, the gas tightness is met, the whole detecting process is quite convenient, and the operation is simple.
