DETAILED DESCRIPTION

[0023] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figure 1-6As shown, a quick-release electronic price tag includes a price tag body 10 arranged on a power supply track 100 and a positioning component 20 fixed to one side of the price tag body, the positioning component 20 is provided with a positioning bead 30 that can protrude from the surface of the positioning component and slide with the power supply track, the positioning bead 30 is connected to the positioning component 20 via a spring 310, and the power supply track 100 has a groove 101 for buckling the positioning bead.

[0025] In this embodiment, the positioning assembly includes an outer shell 210 , and the side of the outer shell has a groove 211 for limiting the positioning bead. One end of the spring 310 is fixedly connected to the inner cavity of the groove and the other end is fixedly connected to the positioning bead 30 .

[0026] In this embodiment, the upper portion of the positioning assembly 20 further comprises a pair of conductive springs 40 for obtaining electricity, and a conductive strip 102 in contact with the conductive springs is fixed in the power supply track 100 .

[0027] In this embodiment, the positioning component is located at the top of the electronic price tag, and the positioning beads 30 are located on both sides of the positioning component. The power supply track 100 has a track groove 103 under it for the electronic price tag positioning component to be placed in. The groove 101 is located on both sides of the track groove corresponding to the positioning beads 30.

[0028] When in use, the electronic price tag is pushed in from the bottom of the track groove 103 with force, and the positioning bead 30 and the spring 310 are connected. The spring 310 is connected to the groove 211. After the force is applied, the spring 310 is compressed to make the positioning bead 30 retract into the groove 211. When the positioning assembly goes deep into the track groove 103, the spring 310 is reset, and the positioning bead 30 is pushed out into the groove 101. The positioning bead 30 supports the price tag body 10 to prevent the price tag body 10 from falling. When disassembling, you only need to pull it down with force. After the force is applied, the spring 310 is compressed to make the positioning bead 30 retract into the groove 211, and the electronic price tag can be separated from the power supply track.
