Description

Technical Field

[0001] The utility model relates to the technical field of electroencephalographic bionic electric stimulators, in particular to a supporting device for electroencephalographic bionic electric stimulators. Background Art

[0002] The EEG bionic electric stimulator is an electrotherapy device that uses direct digital frequency synthesis technology to synthesize EEG simulated low-frequency bioelectric current. Through electrodes attached to the skin of the mastoids, temples or Fengchi points on both sides of the ears, it uses bionic electric current to non-invasively penetrate the skull barrier from outside the skull to stimulate the cerebellar fastigial nucleus area. This current stimulation can activate the inherent neuroprotection mechanism of the brain, improve brain blood circulation, and accelerate the repair of brain damage.

[0003] In the existing technology, such as the document with publication number CN219655726U, a brain electro-mimetic electric stimulator stand is specifically disclosed. In this document, the device balances the center of gravity of the brain electro-mimetic electric stimulator placed on the top of the stand by setting a stabilizing device, lowers the center of gravity position of the entire device, and makes the device more stable when moving. During daily use, the stand is subject to accidental external collisions and may still topple over. At this time, the rated brain electro-mimetic electric stimulator installed on the top of the stand may still collide with the ground and be damaged. For this reason, we propose a brain electro-mimetic electric stimulator support device. Utility Model Content

Hold the handle and turn the crank to drive the fixed shaft to rotate, drive the gear to rotate, drive the gear to move the toothed plate up and down, and drive the telescopic rod to move through the toothed plate, so that the height of the EEG bionic electrical stimulator can be adjusted. After adjustment, release the shift block. Under the tension of the spring, the bottom of the positioning rod abuts against the outer wall of the fixed shaft. Slightly turn the crank to drive the fixed shaft to rotate, so that the positioning rod is stuck in the fixed shaft, thereby fixing the fixed shaft. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the support plate 5 located between the two extension plates 10 inside the support column 1 will drive the limit block 4 to rotate along the first rotating shaft 3. During the tipping process of the support column 1, the support plate 5 always remains vertical to the ground until the roller 8 on the support arm 6 contacts the ground. At this time, a triangular support is formed between the support plate 5 and the support column 1, and the upper end of the limit block 4 abuts against the outer wall of the support column 1 to form a limit. The weight of the counterweight plate 9 is greater than that of the electroencephalographic bionic electric stimulator 26. At this time, the electroencephalographic bionic electric stimulator 26 will not collide with the ground, thereby effectively protecting the electroencephalographic bionic electric stimulator 26.

[0023] Reference Figure 1 and Figure 2 The inner walls of the outer ends of the multiple extension plates 10 are rotatably connected with connecting shafts 11, and the bottoms of the multiple connecting shafts 11 are fixedly connected with rollers 8, and the rollers 8 are universal wheels, and a brake member is provided on one side of the universal wheel.

[0027] Working principle: When the supporting device falls over, the electroencephalographic bionic electric stimulator 26 will fall between the two extension plates 10 connected to the outer wall of the counterweight plate 9. At this time, the support plate 5 located between the two extension plates 10 inside the support column 1 will drive the limit block 4 to rotate along the first rotating shaft 3. The support plate 5 will always remain vertical to the ground during the tilting process of the support column 1 until the roller 8 on the support arm 6 contacts the ground. At this time, a triangular support is formed between the support plate 5 and the support column 1, and the upper end of the limit block 4 abuts against the outer wall of the support column 1 to form a limit. The weight of the counterweight plate 9 is greater than the electroencephalographic bionic electric stimulator 26. At this time, the electroencephalographic bionic electric stimulator 26 will not collide with the ground, thereby effectively protecting the electroencephalographic bionic electric stimulator 26.

After adjustment, the shift block 24 is released. Under the pulling force of the spring 23, the bottom of the positioning rod 21 is in contact with the outer wall of the fixed shaft 16. The crank 17 is slightly turned to drive the fixed shaft 16 to rotate, so that the positioning rod 21 is stuck in the fixed shaft 16, so that the fixed shaft 16 can be fixed.
