Description

Technical Field

[0001] The utility model relates to the technical field of couplers, in particular to a novel coupler. Background Art

[0002] As we all know, a coupler is a device used to connect or disconnect two or more devices or systems. It can transfer signals, energy or fluid from one system to another. Couplers are widely used in power systems, communication systems, mechanical systems, fluid systems and other fields.

[0003] However, traditional couplers usually use a direct plug-in connection method, relying only on the contact between the pin and the socket to maintain the connection. This connection method is prone to cause the pin to loosen or fall off when subjected to vibration, impact or improper operation, thereby causing the coupler to fall off. In addition, the traditional coupler part is 1mm away from the exposed surface, which does not meet safety requirements and is easy for children to touch. There are 5 pins, one of which is the ground wire. This pin is idle, making the product look clumsy. Therefore, technical improvements are urgently needed. Utility Model Content

When the coupler is used, the limit rods on both sides are pressed, and the limit spring inside the cushion block is compressed by the force. When the pin is connected with the positioning interface, the limit rod is loosened, and the limit spring releases the force to drive the cushion block to rebound, thereby pushing the front end of the limit rod to make the clamping cushion block engage with the limit hole, thereby performing secondary limiting on the whole, thereby effectively preventing the coupler from loosening or falling off due to vibration or impact, and improving the reliability of the connection.
