Description

Technical Field

[0001] The utility model relates to the technical field of cable connection joints, in particular to a quick connector for welding cables of a welding machine. Background Art

[0002] At present, the welding cable of a welding machine is connected to a socket for power supply through a plug-in quick connector. Due to the plug-in connection, during use, affected by the dragging displacement of the welding cable, the contact of the connector is likely to become loose or even separated, and it will continuously burn and damage under the impact of the welding current. Especially when used in the wild or in an environment with an uneven working surface, the burning and damage situation is more serious. Such a connector poses a safety hazard to construction when burned. Since the burning directly affects the welding current, causing the welding current to be unstable, seriously affecting the welding quality. Content of the Utility Model

An insertion block is arranged on the plug body. A slot is formed in the upper wall of the insertion block, and a fixing structure is arranged on the insertion block.

[0004] The fixing structure includes an insertion plate matching the slot. The insertion plate is inserted into the slot. A connecting plate is installed on the upper wall of the insertion plate. A movable plate slidably penetrates through the connecting plate. A top plate is installed at the top end of the movable plate. A first screw rod is spirally penetrated through the top plate. The lower end of the first screw rod rotatably penetrates through the connecting plate.

[0005] The lower end of the movable plate slidably penetrates through a fixing plate. A vertical plate is installed at one end of the fixing plate. A second screw rod is spirally penetrated through the vertical plate. One end of the second screw rod is rotatably connected to the movable plate.

[0006] Preferably, insertion blocks are arranged on four side walls of the plug body.

[0007] Preferably, turntables are arranged on both the first screw rod and the second screw rod.

[0008] Preferably, rollers are embedded on both left and right side walls of the insertion plate, and the rollers are rotatably arranged on the insertion plate.

[0009] The utility model has the following beneficial effects: The structure of the utility model is reasonable and novel. When in use, insert the plug body into the socket, insert the insertion plate into the slot, rotate the second screw rod to drive the fixing plate to move so that the fixing plate is located below the socket, rotate the first screw rod to drive the top plate to rise, thereby driving the movable plate to rise. By the rising of the movable plate, drive the fixing plate to rise so that the fixing plate adheres to the lower wall of the socket, and the plug body can be fixed on the socket to avoid the plug body being separated from the socket due to pulling.
