Psychological monitoring is mainly used in psychological counseling, case interrogation and other work.

[0003] In the prior art, a psychological monitoring device is usually composed of a wire network, a psychological monitoring module, a power supply and a signal relay module. When in use, the power supply supplies power to the psychological monitoring module through the wire network, and the psychological monitoring module then transmits the monitoring signal to an external computer through the signal relay module. After the device is used up, the wire network and the psychological monitoring module cannot be stored due to the lack of storage components, which makes the wire network and the psychological monitoring module easily damaged and reduces the service life of the device.

[0013] In summary, the beneficial effects of the utility model are:

[0014] 1. The utility model arranges a connecting belt below the wire net and an adjusting mechanism inside the placement groove. When the device is worn, the guide plate is pulled outward by the extension plate, and the guide plate pulls the control plate to move outward. The spring is compressed, and the control plate moves away from the connecting belt, and the lower end of the connecting belt is pulled to move, so as to adjust the stretching size of the wire net, so that the outer contour of the wire net coincides with the wearer's head, thereby ensuring that the brain wave monitoring module can fit the wearer's head to ensure the accuracy of the monitoring results.

[0015] 2. The utility model provides a placement slot on the second mounting block, and sets a limit strip inside the placement slot. After the device is used, the wire network and the EEG monitoring module are stored in the placement slot, and then the first mounting block is inserted into the placement slot. The limit strip can limit the depth of the first mounting block inserted into the placement slot to prevent the first mounting block from being inserted too deeply and squeezing the wire network. At the same time, since the limit strip is magnetic and the outer surface of the first mounting block is covered with an iron sheet, after the first mounting block is inserted into the placement slot, the limit strip can adsorb the first mounting block to prevent the first mounting block and the second mounting block from opening automatically, thereby realizing the storage and protection of the wire network and the EEG monitoring module and improving the service life of the device.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0022] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 A head-mounted EEG psychological monitoring device is shown.

[0023] The first embodiment of the utility model refers to Figure 1 A head-mounted brain wave psychological monitoring device includes a first mounting block 1 and a second mounting block 2. The first mounting block 1 and the second mounting block 2 are both arc-shaped structures. When the device is worn, the first mounting block 1 and the second mounting block 2 with arc-shaped structures can fit the wearer's head better, improving the comfort of using the device. A wire net 3 is arranged between the first mounting block 1 and the second mounting block 2. The wire net 3 is used for the transmission of current and signals. The crossover of the wire net 3 is provided with a brain wave monitoring module 4. The brain wave monitoring module 4 can monitor the brain waves of the wearer. An adjustment mechanism for stretching and fixing the wire net 3 is arranged inside the second mounting block 2. A battery 11 and a signal transfer module 12 are arranged in the installation groove provided on the outer arc surface of the first installation block 1. The input end of the brain wave monitoring module 4 is electrically connected to the output end of the battery 11 through the wire network 3. The battery supplies power to the brain wave monitoring module 4 through the wire network 3. The output end of the brain wave monitoring module 4 is electrically connected to the input end of the signal transfer module 12 through the wire network 3. The signal transfer module 12 is composed of a signal receiver and a signal transmitter. The brain wave monitoring module 4 transmits the monitored brain waves to the signal receiver inside the signal transfer module 12 through the wire network 3. The signal transmitter inside the signal transfer module 12 then transmits the signal to the outside through Bluetooth or WiFi, so that the external computer can receive the signal. As a preferred embodiment, Figure 2 and Figure 3As shown, a connecting belt 5 is provided inside the second mounting block 2, and the connecting belt 5 is a non-elastic nylon belt. The upper part of the connecting belt 5 is connected to the wire net 3, and the lower end of the connecting belt 5 passes through the avoidance opening opened at the bottom of the placement groove 201. The adjustment mechanism includes a guide plate 6, a control plate 8, a guide rod 9 and a spring 10. The guide plate 6 is slidably set in the sliding opening opened on the outer arc surface of the second mounting block 2, and the control plate 8 is fixedly set at the inner end of the guide plate 6. The connecting belt 5 is located between the inner arc plate of the second mounting block 2 and the control plate 8. The connecting belt 5 is fixed by the mutual compression of the control plate 8 and the inner arc plate of the second mounting block 2, so that the wire net 3 is connected and fixed to the second mounting block 2. The guide rod 9 is set inside the second mounting block 2, and the guide hole 801 opened on the control plate 8 is slidably connected to the guide rod 9. The outer sleeve of the guide rod 9 is provided with a spring 10, and the control plate 8 and the spring 10 are elastically connected. The outer end of the guide plate 6 is provided with an extension plate 7.

[0024] When the device is worn, the guide plate 6 is pulled outward by the extension plate 7, and the guide plate 6 pulls the control plate 8 outward, the spring 10 is compressed, the control plate 8 moves away from the connecting belt 5, and the lower end of the connecting belt 5 is pulled to move, so as to adjust the stretching size of the wire mesh 3 so that the outer contour of the wire mesh 3 matches the wearer's head, thereby ensuring that the brain wave monitoring module 4 can fit the wearer's head to ensure the accuracy of the monitoring results.

[0025] The second embodiment of the utility model refers to Figure 1 and Figure 4 As shown, a placement groove 201 is provided on the upper part of the second mounting block 2, and the upper opening of the placement groove 201 coincides with the mounting block 1. Preferably, a limit strip 202 is provided at the inner upper end of the placement groove 201, and the limit strip 202 is a magnetic limit strip. The outer surface of the first mounting block 1 is covered with an iron sheet.

[0026] After the device is used, the wire mesh 3 and the brain wave monitoring module 4 are placed in the placement groove 201, and then the first mounting block 1 is inserted into the placement groove 201. The limit bar 202 can limit the depth of the first mounting block 1 inserted into the placement groove 201 to prevent the first mounting block 1 from being inserted too deeply and squeezing the wire mesh 3. At the same time, since the limit bar 202 is magnetic and the outer surface of the first mounting block 1 is covered with iron sheets, after the first mounting block 1 is inserted into the placement groove 201, the limit bar 202 can adsorb the first mounting block 1 to prevent the first mounting block 1 and the second mounting block 2 from opening automatically, thereby providing protection for the wire mesh 3 and the brain wave monitoring module 4 and improving the service life of the device.
