[0033] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0034] Example 1

[0035] A retractable electrode sheet, such as Figures 1 to 4 As shown, a fitting ring layer 200 for fitting to the skin, a stretchable and foldable telescopic part 100, a conductive layer 300 and a button 400 for assembling with an external conductive line are provided. The fitting ring layer 200 is connected to the outer periphery of the telescopic part 100, the conductive layer 300 is provided on the lower surface of the telescopic part 100, the button 400 is assembled on the upper surface of the telescopic part 100, and the button 400 is electrically connected to the conductive layer 300.

[0036] It should be noted that when the retractable electrode sheet is in contact with the skin, the plane where the skin is located is defined as the lower surface.

[0037] When the telescopic part 100 is extended, the conductive layer 300 is not in contact with the skin, and the upper end of the telescopic part 100 is clamped with fingers to provide support for the button 400, so that the button 400 and the conductive thread can be easily fastened. Figure 1 and Figure 2 As shown; when the telescopic portion 100 is folded, the conductive layer 300 is in contact with the skin, and the conductive layer 300 can monitor and collect physiological parameters, or transmit electrical stimulation signals.

[0038] The telescopic part 100 is provided with multiple layers of ring bodies 110, and the diameters of all the ring bodies 110 decrease from the outside to the inside, and the ring bodies 110 are foldably connected with the outer and adjacent ring bodies 110. All the ring bodies 110 are distributed in concentric circles. All the ring bodies 110 are defined as inner ring bodies 110 and outer ring bodies 110, respectively. The upper ends of the inner ring bodies 110 and the outer ring bodies 110 are foldably connected, and the lower end of the outer ring body 110 is also connected to the bonding ring layer 200, and the conductive layer 300 is located at the center of the inner ring body 110.

[0039] It should be noted that all the ring bodies 110 are connected as one body, and the connection between the ring bodies 110 and the ring bodies 110 is deformed to achieve folding. When the telescopic part 100 is extended, the connection between the ring body 110 and the adjacent ring body 110 stretches upward, so that the ring body 110 stretches upward and the overall height is the largest; when the telescopic part 100 is folded, the connection between the ring body 110 and the adjacent ring body 110 shrinks between the ring body 110 and the adjacent ring body 110, so that all the ring bodies 110 are nested layer by layer, so that the height is the smallest. The material of the telescopic part 100 can be silicone, plastic, fiber, etc.

[0040] All the ring bodies 110 are respectively defined as an inner ring body 110, a middle ring body 110 and an outer ring body 110. The inner ring body 110 is foldably connected to the middle ring body 110. The upper end of the outer ring body 110 is foldably connected to the middle ring body 110. The lower end of the outer ring body 110 is also connected to the bonding ring layer 200. The conductive layer 300 is located at the center of the inner ring body 110.

[0041] The telescopic portion 100 is further provided with a top layer 120 , the inner ring body 110 surrounds and is connected to the outer periphery of the top layer 120 , the conductive layer 300 is provided on the lower surface of the top layer 120 , and the button 400 is fixedly assembled on the top layer 120 .

[0042] The conductive layer 300 protrudes from the lower end of the inner ring body 110; when the telescopic portion 100 is folded, the lower surface of the conductive layer 300 is flush with or protrudes from the lower surface of the fitting ring layer 200, such as Figure 5 and Figure 6 .

[0043] It should be noted that the function of the lower surface of the conductive layer 300 being flush with or protruding from the lower surface of the fitting ring layer 200 is to ensure that the conductive layer 300 is in contact with the skin when the fitting ring layer 200 is in contact with the skin.

[0044] The retractable electrode sheet of the present invention is further provided with a gasket 500, which is fixedly mounted on the lower surface of the top layer 120, and the conductive layer 300 is fixedly mounted on the lower surface of the gasket 500. The gasket 500 is provided with a through hole (not shown in the figure), and a conductor 600 is mounted inside the through hole, one end of the conductor 600 is electrically connected to the button 400, and the other end of the conductor 600 is electrically connected to the conductive layer 300.

[0045] It should be noted that the function of the gasket 500 of the present invention is to ensure that the thickness of the conductive layer 300 remains the same as that of the conductive layer 300 of the electrode sheet in the prior art, so that the conductive layer 300 can be in close contact with the skin.

[0046] The retractable electrode sheet can be retracted. Before the button 400 is assembled with the conductive wire, the retractable portion 100 can be stretched and clamped with fingers to provide support for the retractable portion 100 to buckle the button 400 with the conductive wire without squeezing the skin.

[0048] A retractable electrode sheet, such as Figure 7 As shown, other features are the same as those of Example 1, except that: all ring bodies 110 are respectively defined as inner ring bodies 110 and outer ring bodies 110, the upper ends of the inner ring bodies 110 and the outer ring bodies 110 are foldably connected, the lower end of the outer ring body 110 is also connected to the fitting ring layer 200, and the conductive layer 300 is located at the center of the inner ring body 110.

[0049] Compared with the first embodiment, the present embodiment simplifies the structure of the telescopic part 100 and reduces the production cost.

[0050] Example 3

This embodiment is described by taking two layers of middle ring bodies 110 as an example, and of course, the data of the middle ring bodies 110 can also be set according to actual conditions, such as three layers, five layers, etc.

[0052] Compared with the first embodiment, the present embodiment can increase the extension height of the telescopic portion 100, so as to facilitate the finger clamping of the button 400 when assembling the conductive wire.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
