Description

Air tank filling connecting device Technical Field The application relates to the technical field of containers or parts for filling and discharging containers, in particular to a gas tank filling and connecting device. Background The patent document of CN217978356U describes a gas tank safety protection filling connecting device, which comprises a base frame, metal clamping blocks, a screw rod, a handle and a filling nozzle used for being connected with a filling pipeline, wherein the base frame is provided with two metal guide rods, the metal clamping blocks transversely span between the two metal guide rods and are provided with through holes, a plastic sleeve sleeved outside the metal guide rods is fixedly arranged in each through hole, one end of the screw rod is arranged on the metal clamping block, and the handle is arranged at the other end of the screw rod. The utility model uses the screw pair formed by the screw rod and the screw hole to realize the mechanical clamping of the air nozzle of the air tank, so that the air nozzle of the air tank is stably clamped between the metal clamping block and the air nozzle, the air inflation safety can be improved, and the risk of air leakage in the air inflation process is reduced. In the above patent document, therefore, the metal clamping block needs to be self-locked on the screw, the screw angle may reduce the self-locking performance, so that the screw angle on the screw is usually designed smaller in order to ensure that the metal clamping block can be self-locked on the screw, and the smaller the screw angle is, the smaller the axial movement distance ‌ caused by rotating the same angle is, so that when the gas tank safety protection filling connection device disclosed in the above patent document is used, the metal clamping block needs to be moved for a certain distance, the number of turns required to rotate the screw is more, and the dismounting efficiency is low. Disclosure of Invention The present utility model aims to solve at least one of the technical problems existing in the prior art.
