DETAILED DESCRIPTION

[0025] 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.

[0026] The utility model provides Figure 1-Figure 3 An ultra-flexible titanium metal fiber fabric dry electrode is shown, characterized in that it includes an oil shell 1, hydraulic oil is arranged inside the oil shell 1 for transmission, a sticking ring 2 is clamped on the upper end of the oil shell 1, and an annular concave-convex spring piece is arranged inside the sticking ring 2 for compressing and stretching the internal space of the oil shell 1, a sealing ring 3 is fixedly clamped in the middle of the sticking ring 2 for sealing the gap between the sticking ring 2 and the telescopic sleeve 4, and for supporting the inner side of the sticking ring 2, a telescopic sleeve 4 is fixedly connected at the center of the lower end of the sealing ring 3 for telescoping the titanium fiber patch 6, a hydraulic conduction pipe 5 is fixedly connected at the center of the lower end of the telescopic sleeve 4 for guiding the hydraulic oil, a titanium fiber patch 6 is slidably connected inside the upper end of the telescopic sleeve 4, and the lower end of the titanium fiber patch 6 is connected to the detection mechanism through a connecting harness for collecting and conducting bioelectricity.

[0027] Preferably, the titanium fiber patch 6 is woven from titanium metal fibers and can collect bioelectricity. When the detection object is detected, the oil shell 1 is attached to the surface of the detection object, and the detection object will form a downward extrusion pressure on the sticking ring 2, and the sticking ring 2 will bounce downward into the oil shell 1. Since the upper end of the oil shell 1 is blocked by the connection between the sticking ring 2 and the sealing ring 3, the sticking ring 2 can compress the internal space between the oil shell 1 and the sticking ring 2 through the downward bounce of the internal annular concave and convex spring piece, allowing the hydraulic oil inside the oil shell 1 to enter the hydraulic conduction pipe 5, thereby acting on the titanium fiber patch 6 inside the telescopic sleeve 4, causing the titanium fiber patch 6 to pop up upward, thereby collecting bioelectricity and conducting the collected bioelectricity to the detection mechanism through the wiring harness.

[0028] like Figure 2-Figure 4As shown, the lower end of the titanium fiber patch 6 is fixedly connected to a telescopic head 7, and the telescopic head 7 is slidably connected to the inside of the telescopic sleeve 4, which is used to support the titanium fiber patch 6 and control the expansion and contraction of the titanium fiber patch 6. The titanium fiber patch 6 and the telescopic head 7 are both provided with air holes at the center, and the air holes are connected to the inside of the upper end of the hydraulic transmission tube 5, which is used to balance the internal and external air pressures of the telescopic sleeve 4. The center of the lower end of the telescopic head 7 is fixedly connected to a push-pull spring 8, and the push-pull spring 8 is located on the upper side of the hydraulic transmission tube 5, which is used to push and pull the telescopic head 7. The lower end of the push-pull spring 8 is fixedly connected to a conductive The slide block 9 is slidably connected to the lower side of the hydraulic transmission tube 5, and is used to compress and stretch the push-pull spring 8. The transmission slide block 9 is composed of a cone at the lower end and a cylinder at the upper end, and the cylinder at the upper end of the transmission slide block 9 is tightly fitted with the inner wall of the hydraulic transmission tube 5. The cone of the transmission slide block 9 can prevent the transmission slide block 9 from being adsorbed on the bottom of the oil shell 1. A plurality of through holes 10 are opened inside the lower end of the hydraulic transmission tube 5, and a plurality of through holes 10 are opened at the intersection of the hydraulic transmission tube 5 and the oil shell 1, and are used to introduce and export hydraulic oil into and out of the hydraulic transmission tube 5.

[0029] Preferably, when the concave and convex spring pieces of the sticking ring 2 bulge upward, the internal space between the oil shell 1 and the sticking ring 2 remains unchanged, and the telescopic head 7 and the conductive slider 9 are both located at the bottom. Since the push-pull spring 8 is in a relaxed state when the telescopic head 7 and the conductive slider 9 are both located at the bottom, the push-pull spring 8 will not generate elastic force on the telescopic head 7, so that the titanium fiber patch 6 and the telescopic head 7 are contracted inside the telescopic sleeve 4, preventing the titanium fiber patch 6 from being bumped.

[0030] Preferably, when the concave and convex spring pieces of the sticking ring 2 are subjected to downward squeezing force, the sticking ring 2 will bulge downward. At this time, the internal space between the oil shell 1 and the sticking ring 2 becomes smaller, so the sticking ring 2 will squeeze the hydraulic oil inside the oil shell 1. Under the squeezing of the sticking ring 2, the hydraulic oil enters the lower end of the hydraulic conduction tube 5 through multiple through holes 10, and pushes the conduction slider 9 to slide upward. The conduction slider 9 squeezes the push-pull spring 8 by sliding upward. The push-pull spring 8 pushes the titanium fiber patch 6 and the telescopic head 7 upward through elastic force, so that the titanium fiber patch 6 and the telescopic head 7 slide out of the telescopic sleeve 4 and protrude outside the oil shell 1 to contact the detection object. At the same time, the detection object will prevent the titanium fiber patch 6 from continuing to slide upward, so that the push-pull spring 8 is in a compressed state, so that the titanium fiber patch 6 can adjust the distance with the detection object through the push-pull spring 8, so that the titanium fiber patch 6 can stably contact the detection object, and then collect bioelectricity.

[0031] like Figure 5As shown, a limiting slide groove 11 is provided inside the upper side of the center of the left and right ends of the telescopic sleeve 4, and the limiting slide groove 11 is located on the lower side of the titanium fiber patch 6, which is used for the sliding of the linkage connecting rod 12. The linkage connecting rods 12 are fixedly connected at the centers of the left and right ends of the telescopic head 7, and the two linkage connecting rods 12 are respectively slidably connected in the two limiting slide grooves 11, which are used to connect the telescopic head 7 and the return push ring 13, so that the return push ring 13 can be linked with the telescopic head 7 and limit the sliding position of the titanium fiber patch 6 and the telescopic head 7. The upper ends of the two linkage connecting rods 12 are fixedly connected with the return push ring 13 through a vertical connecting rod, which is used to push the lower end of the convex sticker ring 2. The return push ring 13 is arranged in an annular shape and is coaxial with the telescopic sleeve 4, and the return push ring 13 is located directly below the annular concave and convex spring piece of the sticker ring 2.

[0032] Preferably, when the titanium fiber patch 6 is extended to contact the detection object, the titanium fiber patch 6 and the telescopic head 7 are blocked by the detection object and will not slide to the uppermost side. At this time, the return push ring 13 connected to the telescopic head 7 through the linkage link 12 cannot touch the bottom of the patch ring 2. When the detection object is separated from the titanium fiber patch 6, the upper end of the titanium fiber patch 6 is not blocked, so that the titanium fiber patch 6 and the telescopic head 7 will slide to the uppermost side under the action of the push-pull spring 8, and the push-pull spring 8 is in a relaxed state when the titanium fiber patch 6 and the telescopic head 7 slide to the uppermost side. At this time, the return push ring 13 will follow As the telescopic head 7 slides to the uppermost side, it will push upward on the bottom of the concave-convex spring sheet inside the sticking ring 2, causing the concave-convex spring sheet inside the sticking ring 2 to bounce upward, thereby increasing the internal space between the oil shell 1 and the sticking ring 2. The negative pressure inside the oil shell 1 will draw out all the hydraulic oil from the inside of the hydraulic conduction pipe 5. The conduction slider 9 will slide downward without the support of the hydraulic oil, and pull the push-pull spring 8 downward. The push-pull spring 8 will pull the titanium fiber patch 6 and the telescopic head 7 downward through the elastic force, so that the titanium fiber patch 6 and the telescopic head 7 will retract into the telescopic sliding sleeve 4 to prevent them from being bumped. Repeat the above steps for the next inspection.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
