[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] Reference Figure 1-3The utility model provides an embodiment: a head fixing mechanism of an electric stimulation device, comprising a support frame 1, a support leg 2 is fixedly connected to the bottom of the support frame 1, a rotating rod 6 is rotatably connected to the top of the support frame 1, a connecting frame 5 is fixedly connected to the right side of the top wall of the support frame 1, a fixing ring 12 is fixedly connected to the top of the connecting frame 5, an end face cam 9 is fixedly connected to the top wall of the rotating rod 6, a groove 7 is provided on the outer wall of the end face cam 9, a limiting ring 10 is fixedly connected to the top of the inner wall of the fixing ring 12, a telescopic rod 11 is slidably connected to the inside of the limiting ring 10, the end of the telescopic rod 11 is rotatably connected to a ball 8, the ball 8 is slidably connected to the inside of the groove 7, the top of the telescopic rod 11 is fixedly connected to an extension frame 4, and the right end of the extension frame 4 is fixedly connected to a wearing mechanism 3.
[0028] Specifically, rotating the rotating rod 6 drives the end face cam 9 to rotate. When the groove 7 rotates, it drives the ball 8 to move up and down along its direction. The limit ring 10 prevents the telescopic rod 11 from shaking left and right. When the telescopic rod 11 moves, it drives the extension frame 4 to move up and down, thereby changing the tension of the external wire 301. When the wearer's head is at a low height, the telescopic rod 11 slides downward, and the external wire 301 becomes looser when the extension frame 4 descends, preventing the external wire 301 from pulling the electrode sheet 303 and causing it to detach from the wearer's head.
[0029] The wearing mechanism 3 includes a support ring 306 and a fitting component. The left and right ends of the interior of the support ring 306 are fixedly connected with connecting plates 305, and the adjacent sides of the outer walls of the two connecting plates 305 are fixedly connected with support plates 313. The middle and lower part of the interior of the support ring 306 is fixedly connected with a support block 316, the front end of the support block 316 is fixedly connected with a second rotating shaft 317, the middle part of the second rotating shaft 317 is rotatably connected with a pillow pad 318, and the lower end of one side of the outer wall of the pillow pad 318 is fixedly connected with a third rotating shaft 319, the lower end of the inner wall of the support ring 306 is fixedly connected with a fixing box 314, the interior of the fixing box 314 is fixedly connected with a spring 323, the front end of the spring 323 is fixedly connected with a slider 320, the left end of the slider 320 is rotatably connected to the inside of the third rotating shaft 319, and the fitting component is fixedly connected to the front end of the outer wall of the support ring 306.
[0030] Specifically, the support ring 306 provides support on both sides of the wearer's head to prevent the wearer's head from squeezing the electrode sheet 303 and changing the fitting position of the electrode sheet 303. After the wearer's neck squeezes the pillow pad 318, the spring 323 contracts to make the slider 320 slide, so that the wearer's rest does not affect the fitting position of the electrode sheet 303.
[0031] The fitting component includes a first rotating shaft 307, and the two first rotating shafts 307 are respectively fixedly connected to the front sides of the outer walls of the two support plates 313; the inner rotation connection of the left end first rotating shaft 307 is connected to the second fitting ring 312, and the right end of the rear side of the outer wall of the second fitting ring 312 is fixedly connected to the buckle 315; the inner rotation connection of the right end first rotating shaft 307 is connected to the first fitting ring 308, and the outer wall of the first fitting ring 308 is fixedly connected with multiple snap rings 309 at equal intervals; the left end of the first fitting ring 308 is provided with a hollow groove 310, and the left side of the outer wall of the hollow groove 310 is provided with a limiting groove 311, and the right end of the second fitting ring 312 passes through the limiting groove 311.
[0032] Specifically, through the cooperation between the buckle 315 and different snap rings 309, the first snap ring 308 and the second snap ring 312 are more closely connected, and the limiting groove 311 gives the second snap ring 312 a more fixed snapping effect.
[0033] The wearing mechanism 3 also includes a card slot 321, and two card slots 321 are respectively opened on the front and rear sides of the outer wall of the slider 320, and the front and rear sides of the inner left end of the fixed box 314 are fixedly connected with a card block 322, and the two card blocks 322 are respectively slidably connected to the inside of the corresponding card slot 321.
[0034] Specifically, the sliding connection between the locking groove 321 and the locking block 322 provides a limiting effect on the slider 320 to prevent the slider 320 from being separated from the fixing box 314 .
[0035] The right end of the extension frame 4 is fixedly connected to an external wire 301, the end of the external wire 301 is fixedly connected to a connecting ring 302, the bottom of the outer wall of the connecting ring 302 is fixedly connected to an electrode sheet 303, the outer walls of the electrode sheet 303 are fixedly connected to telescopic bands 304 on the left and right, and the ends of the two telescopic bands 304 are respectively fixedly connected to the top walls of the two support plates 313.
[0036] Specifically, the electrode sheet 303 is fixed on the top of the wearer's head more closely by means of the retractable belt 304 , and after the electrode sheet 303 is worn on the patient's head, electromagnetic transmission is completed through electrical connection.
[0037] Working principle: rotating the rotating rod 6 drives the end face cam 9 to rotate, and the groove 7 rotates to drive the ball 8 to move up and down along its direction, thereby driving the telescopic rod 11 to move up and down, so that the electrode sheet 303 in the wearing mechanism 3 fits more closely to the wearer's head, avoiding the wearer's head squeezing the electrode sheet 303 and changing the fitting position of the electrode sheet 303, and after the wearer's neck squeezes the pillow pad 318, the spring 323 gives the slider 320 a force to slide toward the outside of the fixed box 314, so that the slider 320 supports the pillow pad 318 to fit the wearer's neck, so that the wearer's rest does not affect the fitting position of the electrode sheet 303.
[0038] 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.
