DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a plug bidirectional extension cord with a quick-release function, comprising a socket row 1, a fixing bracket 2, a fixing bolt 3, a movable plate 4, a fixing splint 5, an extension harness 6, a connecting plug 7, a winding roller 8, a connecting bracket 9, a fixing mechanism 10, a spring 11, a connecting plate 12, a fixing pin 13 and a fixing groove 14.

[0028] When using the two-way extension cord with quick-release plug, Figure 1 and Figure 2As shown, both upper and lower ends of the socket row 1 are fixedly connected with fixed brackets 2. First, the fixed bracket 2 is placed on the mounting back plate. Then, the fixing bolt 3 threadedly connected to the upper end of the fixing bracket 2 is rotated, and the fixing bolt 3 and the movable plate 4 are rotated. The fixing bolt 3 drives the movable plate 4 to slide with the fixing bracket 2, and the rear end of the movable plate 4 is fixedly connected with a fixing clamping plate 5. The movable plate 4 drives the fixing clamping plate 5 to extend and retract, so that the fixing clamping plate 5 is clamped on the external bracket, thereby facilitating the disassembly and assembly of the socket row 1, preventing the socket row 1 from falling during use, and improving the stability of the socket row 1 during use. Figure 3 and Figure 4 As shown, a connection bracket 9 is fixedly connected to the left side of the socket row 1, a winding roller 8 is rotatably connected to the middle of the connection bracket 9, and the extended wire harness 6 is wound around the outer surface of the winding roller 8;

[0029] The winding roller 8 and the connecting bracket 9 are limited by a fixing mechanism 10, which includes a spring 11 sleeved on the outer surface of the connecting bracket 9, a connecting plate 12 fixedly connected to the movable end of the spring 11, a fixing pin 13 for limiting and a fixing groove 14 opened at the upper and lower ends of the winding roller 8. By pulling the connecting plate 12, the connecting plate 12 slides with the connecting bracket 9, and the connecting plate 12 squeezes the spring 11, so that the spring 11 undergoes elastic deformation. At this time, the connecting plate 12 drives the fixing pin 13 to be pulled out from the fixing groove 14. According to the actual length, by pulling the connecting plug 7, the connecting plug 7 drives the extension harness 6 to extend, and the extension harness 6 drives the winding roller 8 and the connecting bracket 9 to rotate. In addition, a spring is provided at the connection between the connecting bracket 9 and the winding roller 8, and the spring is deformed. When the connecting plug 7 is stretched to the corresponding length, the connecting plug 7 is plugged into an external power supply.

[0030] Then release the connecting plate 12, at which time the spring 11 restores its elastic deformation, driving the connecting plate 12 to slide with the connecting bracket 9, and the fixing grooves 14 are set at equal angles on the winding roller 8. The connecting plate 12 drives the fixing pin 13 to engage in the fixing grooves 14 at the corresponding positions, thereby facilitating the limiting of the winding roller 8 and the connecting bracket 9. By winding the extended wire harness 6 around the outer surface of the winding roller 8, it is convenient to wind up and store the extended wire harness 6 to prevent the extended wire harness 6 from being too messy.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
