Abstract

The invention relates to a pouring gun head which comprises a pouring base and a connecting base connected with the pouring base. A pin end installing space is arranged on the connecting base, a pin end communication channel is arranged on the pouring base and the connecting base, the connecting base comprises a sleeve and a connecting drum sleeved outside the sleeve, and a clamping sleeve installing space is formed between the sleeve and the connecting drum. A clamping sleeve capable of sliding in a reciprocating mode along the axial direction is arranged in the clamping sleeve installing space. A first end of the clamping sleeve installing space is provided with a vent, and a second end is provided with a first elastic component enabling the clamping sleeve to reset towards the first end of the clamping sleeve installing space. The sleeve is provided with a locking piece channel penetrating through a sleeve wall transversely and a locking piece movably arranged in the locking piece channel and used for locking a pin end inserted in the sleeve. The clamping sleeve comprises a first inner diameter portion and a second inner diameter portion which are matched with the locking piece selectively in a corresponding mode so as to enable the locking piece to lock or unlock the pin end. Self locking of the pin end can be achieved by leading in compressed air, an automation degree is high, and labor is saved.

Description

technical field [0001] The invention relates to the field of fluid perfusion devices, in particular to a perfusion gun head. Background technique [0002] The air-tightness test of the device, especially the air-tightness test of the air conditioner is an important process after the assembly of the air conditioner in the production process. The air-tightness detection method of the air conditioner external unit is to pour the working medium such as refrigerant into the air conditioner external unit, and then increase the air pressure to a certain level to check whether the air conditioner is leaking. [0003] At present, the refrigerant injection of the external unit of the air conditioner mainly adopts the manual docking method, which has a low degree of automation and high labor intensity. Contents of the invention [0004] The present invention aims to provide a perfusion gun head capable of automatic docking, so as to solve the technical problems of low automation and...
