A quick coupler is a device used for quickly connecting and disconnecting two components or systems. The following is a detailed introduction to it:
working principle
Mechanical locking principle: By using mechanical structures such as buckles, threads, pins, etc., quick connection and fixation can be achieved. Taking the common bayonet type quick connector coupler as an example, the male and female heads are respectively designed with corresponding card slots and card blocks. When connecting, the male head is inserted into the female head, and the card block will automatically fit into the card slot, achieving quick connection. When disassembling, simply press the unlock button or operate the corresponding unlocking device, and the card block will be released from the card slot, completing the separation.
Fluid sealing principle:
In quick coupling couplings involving fluid transmission, sealing elements such as gaskets and O-rings are usually used to ensure the sealing of the connection. When the male and female heads are connected, the sealing element will be compressed and filled in the gap between the male and female heads to prevent fluid leakage. For example, in hydraulic systems, the sealing performance of quick couplings is crucial to ensure that hydraulic oil does not leak and to guarantee the normal operation of the system.
Application scenarios
In the industrial field, in the automated production line of automobile manufacturing workshops, the tool replacement system of robots often uses quick coupling couplings, which can quickly replace tools such as welding guns and paint guns; In chemical pipeline systems, quick coupling couplings facilitate quick connection and disassembly of pipelines, facilitating equipment maintenance and pipeline layout adjustments.
Medical field:
Gas or liquid pipeline connections between medical equipment such as ventilators, infusion pumps, etc. can be quickly and accurately connected using quick coupling couplers, ensuring the normal operation of the equipment and facilitating its movement and combination use.
In the aerospace field, quick connect couplings are commonly used to connect fuel pipelines, hydraulic pipelines, and electrical systems on aircraft. They can be quickly disassembled and assembled during aircraft maintenance and repair, improving maintenance efficiency and ensuring flight safety.
In daily life, the nozzle of the high-pressure cleaning machine is connected to the hose through a quick connector coupler, making it convenient for users to quickly replace different types of nozzles according to their cleaning needs; Some rechargeable household devices, such as electric toothbrushes, wireless chargers, etc., also use quick connect couplers to achieve fast charging and data transmission.
