[0027] See also Figure 1-4 ,The utility model provides a technical solution:

[0028] A portable electroencephalogram signal acquisition device comprises a mounting ring 1, wherein a plurality of groups of storage frames 2 are fixedly arranged on the upper side of the mounting ring 1, a rotating rod 3 is rotatably arranged inside the plurality of storage frames 2, a mounting belt 4 is rolled up on the outer side of the rotating rod 3, a plurality of groups of electroencephalogram signal collectors 11 are fixedly arranged on the inner side of the mounting belt 4, and the mounting belt 4 movably penetrates the storage frame 2 and extends to the outside, a hook 5 is fixedly arranged on the outer side of the mounting belt 4 located at the outer side of the storage frame 2, a plurality of groups of fixing blocks 6 are fixedly arranged on the upper side of the mounting ring 1, and a hanging hole 7 with a docking hook 5 is penetrated on the outer side of the plurality of fixing blocks 6, and by arranging the mounting belt 4 for convenient storage, the electroencephalogram signal collector 11 can be conveniently stored, and while ensuring the normal use of the electroencephalogram signal collector 11, the overall device can be conveniently carried, thereby improving the flexibility of use of the device.

[0029] Specifically, limit plates 8 are fixedly provided on both sides of the mounting belt 4 outside the rotating rod 3 , and the two sets of limit plates 8 can limit the mounting belt 4 to prevent the mounting belt 4 from deviation, thereby ensuring the normal use and storage of the mounting belt 4 .

[0030] Furthermore, a coil spring 9 is sleeved on the outer side of the rotating rod 3, one end of the coil spring 9 is connected to the inner side of the storage frame 2, and the other end of the coil spring 9 is connected to the limit plate 8. The coil spring 9 does not deform in the initial state. When the installation belt 4 is pulled out of the storage frame 2 for use, the rotating rod 3 stretches the coil spring 9 to cause the coil spring 9 to deform. When the hook 5 hangs on the hanging hole 7, the elastic reset of the coil spring 9 can drive the rotating rod 3 to be reinstalled. At this time, the rotating rod 3 can tighten the installation belt 4, so that the EEG signal collector 11 fits the head of the subject better.

[0031] It is worth noting that a hole 10 for docking with the mounting belt 4 is provided through the upper side of the storage frame 2. The hole 10 can facilitate the movement of the mounting belt 4, making it convenient to use and easy to store and carry.

[0032] It is worth noting that a receiving module 12 for docking with the EEG signal collector 11 is fixedly arranged on the outside of the mounting ring 1, and an analyzing module 13 for docking with the receiving module 12 is fixedly arranged on the outside of the mounting ring 1. The EEG signal collector 11 has a built-in wireless signal transmitting device, and the receiving module 12 can receive the signal sent by the EEG signal collector 11 and transmit the signal to the analyzing module 13, and the analyzing module 13 can quickly analyze the signal, so as to obtain specific data.

[0033] In addition, a display 14 of the docking analysis module 13 is fixedly arranged on the outside of the mounting ring 1. The real-time data can be conveniently observed through the display 14 on the outside of the mounting ring 1, which is very convenient and flexible to use.

[0034] It has to be mentioned that an air bag 15 is fixedly provided on the inner side of the mounting ring 1, a connecting tube 16 is fixedly provided on the outer side of the air bag 15, and a balloon 17 is fixedly provided on the outer end of the connecting tube 16. The air bag 15 can be quickly manually inflated by pressing the balloon 17, thereby facilitating the fixation of the mounting ring 1, and after use, the gas in the air bag 15 can be quickly discharged by opening the air release valve on the balloon 17, thereby facilitating the disassembly of the entire device.

[0035] Working principle: first, the mounting ring 1 is put on the subject's head, and then the airbag 15 is inflated by pressing the balloon 17. The gas enters the airbag 15 through the connecting tube 16, thereby expanding the airbag. As the airbag 15 increases, the contact between the airbag 15 and the subject's head becomes closer and closer, so that the mounting ring 1 can be fixed. Then, the hooks 5 on the upper sides of the multiple groups of storage frames 2 are pulled outward, and the hooks 5 move to stretch the mounting belt 4, and the hooks 5 are hung in the hanging holes 7 on the corresponding fixing blocks 6. At this time, the mounting belt 4 fits the subject's head, so that the EEG signal collector 11 on the mounting belt 4 contacts the patient's head, and then the power is turned on to collect EEG signals. The receiving module 12 can receive the signal sent by the EEG signal collector 11, and then the receiving module 12 transmits the signal to the analysis module 13, and the analysis module 13 analyzes the signal, and then transmits the data to the display 14, through which specific information can be easily obtained.
