Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of inflating equipment and relates to a plug assembly and inflating equipment. BACKGROUND

[0002] As a core component of a vehicle suspension system, the performance of a shock absorber directly affects the comfort, stability and safety of the vehicle. The shock absorber is usually filled with high-pressure gas to provide appropriate damping force and support force. Therefore, the inflating process of the shock absorber is a key link in manufacturing and maintenance. A conventional shock absorber inflator mainly injects gas into the interior of the shock absorber through a gas pump and a connecting device. However, in actual operation, the plug of the inflator often cannot follow the piston rod to move away from the sealing ring in the process of being inserted into the sealing contact area of the shock absorber, that is, in the process of being inserted between the piston rod and the sealing ring of the shock absorber, because the position of the plug is fixed. As a result, the plug can extrude the sealing ring, causing damage to the sealing ring and affecting the sealing of the shock absorber.

[0003] Therefore, how to provide a plug assembly and inflating equipment that can maintain the connection relationship between the plug and the piston rod of the shock absorber has become a technical problem to be solved. CONTENT OF THE INVENTION
