Abstract

The invention discloses a pump chuck for being connected with a valve stem of a tire valve. The pump chuck comprises a body, a pivot clamp, a spring, a rubber sealing component, an end cover and a connecting piece. The body is provided with a first hole, a second hole, a third hole and a channel, and the channel is connected with the first hole and the third hole; the pivot clamp is pivotally connected onto the body, a plurality of threads are arranged at an end of the pivot clamp, and the pivot clamp is provided with a sunken portion arranged in the bottom surface of the pivot clamp; the spring is compressed between the pivot clamp and the body; the rubber sealing component is accommodated in the first hole of the body; the end cover is fixed onto the top surface of the body and is positioned above the first hole; the connecting piece is accommodated in the third hole of the body and is used for being connected with a hose of a tire pump. The pump chuck has the advantage that airtight sealing can be affected by contact between the rubber sealing component and the valve stem.

Description

technical field [0001] This invention relates generally to a cartridge for connection to a pump for inflating a bicycle tire or other inflatable, and more particularly to a pump cartridge which can be easily connected to the valve stem of a tire valve and creates an airtight seal . Background technique [0002] When the tires of vehicles are inflated, especially when the tires of two-wheeled vehicles such as bicycles, locomotives, and motor-assisted locomotives are inflated, elastic connectors are generally used for inflation. One end of the connector is coupled to an air source such as a bicycle pump or hand pump and sealed under pressure, while the other end of the connector is sealed to the valve stem of the tire valve. Tire inflators generally have a substantially sealed collet for coupling to the valve stem of a tire valve (or other inflatable item). In order to properly inflate the item, the collet must seal against the air valve to prevent or limit air leakage from ...
