DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1 Reference Figure 1-6, is the first embodiment of the present invention, which provides an educational classroom interactive device, including a wearing mechanism 100, which includes a first clamp 101 and a second clamp 102, the first clamp 101 and the second clamp 102 are connected by setting two binding members 103, the bottom surface of the first clamp 101 is vertically rotatably provided with a winding member 104, the top surface of the second clamp 102 is fixedly provided with an auxiliary belt 105, the end of the auxiliary belt 105 away from the second clamp 102 is inserted into the first clamp 101 and wound around the winding member 104, the winding member 104 includes a winding rod 104a, the lower end of the winding rod 104a extends out of the first clamp 101 and is fixedly sleeved with a cylinder 104b, the inner bottom wall of the cylinder 104b is fixedly provided with a first torsion spring 104c, the first One end of the torsion spring 104c away from the cylinder 104b is fixedly connected to the bottom surface of the first clamp 101, and the first torsion spring 104c is movably sleeved on the winding rod 104a. When the distance between the first clamp 101 and the second clamp 102 increases, the auxiliary belt 105 pulls the winding rod 104a and the cylinder 104b to rotate and causes the first torsion spring 104c to twist and deform. When the distance between the first clamp 101 and the second clamp 102 decreases, the auxiliary belt 105 loses its tension. At this time, the first torsion spring 104c drives the cylinder 104b and the winding rod 104a to rotate and wind the auxiliary belt 105. The cylinder 104b facilitates the isolation of the first torsion spring 104c from the user's hair, thereby reducing the possibility of the user's hair being caught in the first torsion spring 104c.

[0042] A neck stopper 106 is fixedly provided at the bottom of the first clamp 101. The neck stopper 106 is an arc-shaped plate. Both ends of the neck stopper 106 are hingedly provided with a neck fixing plate 106b through a hinge shaft 106a. A first steel cable 106c is wound around the upper end of the hinge shaft 106a. One end of the first steel cable 106c away from the hinge shaft 106a is wound around the winding member 104. A second spring 106d is fixedly provided on the outer wall of the neck fixing plate 106b. One end of the second spring 106d away from the neck fixing plate 106b is connected to the end of the neck stopper 106 plate. When the auxiliary belt 105 pulls the winding member 104 to rotate, the first steel cable 106c is pressed The neck fixing plate 106b is deflected and fits the neck of the user through the second spring 106d, and the first steel cable 106c is wound up through the hinge shaft 106a, so that the device is fixed to the patient's neck through the neck limiter 106 and the two neck fixing plates 106b. At the same time, the stability of the device when worn is increased in cooperation with the restraint 103 and the auxiliary belt 105. When the first torsion spring 104c drives the winding member 104 to rotate and reset, the first steel cable 106c is wound up, and then the first steel cable 106c pulls the hinge shaft 106a to drive the neck fixing plate 106b to deflect and open, so that the user can take the device off the head easily.

[0043] The first clamp 101, the second clamp 102 and the neck fixing plate 106b are all in the shape of arc-shaped plates, and the inner sides of the first clamp 101, the second clamp 102, the neck fixing plate 106b and the neck limiter 106 are all provided with cushions. The cushions can increase the comfort of the first clamp 101, the second clamp 102, the neck fixing plate 106b and the neck limiter 106 when they are in contact with the user, thereby increasing the comfort of the device when in use.

[0044] The fixing mechanism 200 includes an assembly frame 201 fixedly arranged on the outer wall of the second clamp 102, and a display screen 202 is movably arranged in the assembly frame 201. The assembly frame 201 includes a concave plate 201a, and connecting plates 201b are fixedly arranged at both ends of the concave plate 201a. The upper end of the connecting plate 201b is fixedly connected to the outer wall of the second clamp 102, and an arc-shaped limiting plate 201c for limiting the display screen 202 is fixedly arranged on the opposite side of the two connecting plates 201b. The inner side of the arc-shaped limiting plate 201c abuts against the outer wall of the display screen 202. The bottom of the display screen 202 is conveniently limited by the concave plate 201a, and both ends of the display screen 202 are limited by the connecting plate 201b. The outer wall of the display screen 202 is conveniently limited by the arc-shaped limiting plate 201c.

[0045] Text is displayed on the display screen 202, and the identity of the role played by the student is displayed on the display screen 202, and the lines of the role played by the student communicating with the student are displayed on the display screen 202, so that the student can view the line information prompted by the display screen 202 during the conversation, and then achieve the purpose of scene reproduction through role-playing, so that the students can more easily understand the content of the educational class, and cooperate with the prompt information displayed on the display screen 202, so that the students playing the role can make the entire classroom interaction content smoother during the communication process, so that the learning effect of students' learning education is improved, and the content displayed on the display screen 202 can be adjusted according to actual conditions.

[0046] Cavities 203 are provided at both ends of the second clamp 102, and the end of the restraining member 103 away from the first clamp 101 is inserted into the cavity 203 and fixedly connected with a piston block 204. The piston block 204 is connected to the inner bottom wall of the cavity 203 by setting a first spring 205. The height of the inner wall of the cavity 203 is the same as the height of the piston block 204. An opening for the restraining member 103 to pass through is provided at one end of the cavity 203 facing the end of the second arc plate, and the height of the opening is smaller than the height of the piston block 204. By setting the height of the opening to be smaller than the height of the piston block 204, the piston block 204 is limited, thereby reducing the possibility of the piston block 204 and the cavity 203 being separated.

[0047] A suction cup 206 corresponding to the cavity 203 is fixedly inserted on the outer wall of the second clamp 102, and the suction cup 206 is connected to the inner wall of the cavity 203. When the restraining member 103 pulls the piston block 204 to move, the air in the suction cup 206 is sucked into the cavity 203, so that the display screen 202 is adsorbed by the suction cup 206.

[0048] An assembly groove 207 is provided inside the second clamp 102, and a positioning piece 208 is rotatably arranged in the assembly groove 207, so that the positioning rib 208 can be easily assembled through the assembly groove 207; the end of the positioning piece 208 away from the second clamp 102 abuts against the outer wall of the display screen 202, and a second steel cable 209 is fixedly provided on the side of the piston block 204 facing the inner bottom wall of the cavity 203, and the end of the second steel cable 209 away from the piston block 204 is inserted into the assembly groove 207 and wound around the positioning piece 208. When the piston block 204 moves and pulls the second steel cable 209 to move, the second steel cable 209 pulls the positioning piece 208 to operate, so that the positioning piece 208 moves and abuts against the display screen 202, thereby fixing the display screen 202 inside the assembly frame 201.

[0049] One end of the positioning member 208 inserted into the assembly groove 207 is connected to the inner bottom wall of the assembly groove 207 by setting a second torsion spring 208e. The positioning member 208 includes an internal threaded tube 208a and a screw rod 208b. The internal threaded tube 208a is rotatably set in the assembly groove 207. One end of the screw rod 208b is inserted into the internal threaded tube 208a and is threadedly connected to the internal threaded tube 208a. The other end of the screw rod 208b extends out of the second clamp 102 and is fixedly provided with a rubber plate 208c. The rubber plate 208c abuts against the inner wall of the display screen 202. When the piston block 204 moves, the second steel cable 209 is pulled to move. The inner threaded tube 208a is moved, and then the second steel cable 209 is used to pull the inner threaded tube 208a to rotate, and the second torsion spring 208e is caused to twist and deform. As the inner threaded tube 208a rotates, the screw 208b drives the rubber plate 208c to move and contact the display screen 202, and cooperates with the arc-shaped limit plate 201c to fix the display screen 202 in the assembly frame 201. When the piston block 204 is reset, the second steel cable 209 loses its tension. At this time, the second torsion spring 208e recovers its deformation and drives the inner threaded tube 208a to rotate in the opposite direction, thereby causing the screw 208b to drive the rubber plate 208c to reset and separate from the display screen 202.

[0050] A limiting rod 208d is fixedly provided on one side of the rubber sheet 208c facing the second clamp 102, and the limiting rod 208d is movably inserted into the outer wall of the second clamp 102. When the internal threaded tube 208a rotates, the rubber sheet 208c is limited by the limiting rod 208d, thereby prompting the screw 208b to drive the rubber sheet 208c to move along the axial direction of the internal threaded tube 208a and contact the display screen 202, thereby fixing the display screen 202 in the assembly frame 201.

[0051] In summary, the display screen 202 is first inserted into the assembly frame 201, and then the device is placed on the user's head. As the device moves downward and is worn on the user's head, the distance between the first clamp 101 and the second clamp 102 increases, thereby prompting the binding member 103 to pull the piston block 204 to move and prompting the first spring 205 to stretch and deform. As the piston block 204 moves, the air in the suction cup 206 is sucked into the cavity 203, so that the display screen 202 is adsorbed by the suction cup 206, and as the piston block 204 moves, the second steel cable 209 is pulled to move, so that the positioning member 208 moves and conflicts with the display screen 202, thereby fixing the display screen 202 in the assembly frame 201. When the device is not used, it is taken off the user's head. At this time, the distance between the first clamp 101 and the second clamp 102 is reduced, and the first spring 205 pulls the piston block 204 to move and reset, thereby pushing the air in the cavity 203 into the suction cup 206, causing the suction cup 206 to lose suction. At the same time, as the piston block 204 moves, the second steel cable 209 loses its tension. At this time, the second torsion spring 208e drives the positioning member 208 to rotate and reset and separate from the display screen 202, thereby facilitating the operator to disassemble the display screen 202 and put it into a special storage device for protection.

[0052] Example 2 Reference Figure 7-9 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A first air guide cavity 106e is provided in the neck limiter 106. Two second air guide cavities 101a are symmetrically provided inside the first clamp 101. The two second air guide cavities 101a are connected to the first air guide cavity 106e by setting two air guide pipes 101b. The two ends of the two air guide pipes 101b are respectively fixedly inserted on the opposite sides of the neck limiter 106 and the first clamp 101. A fan 106f is fixedly provided on the outer wall of the neck limiter 106. The fan 106f is used to facilitate the delivery of external air to the first air guide cavity 106e. Then, the airflow is delivered to the second air guide cavity 101a through the air guide pipe 101b. As the airflow continuously passes through the first air guide cavity 106e and the second air guide cavity 101a, the neck limiter 106 and the first clamp 101 are cooled, thereby increasing the comfort of the user when using the device.

[0053] Furthermore, the top and bottom surfaces of the neck limiter 106 are fixedly connected with a first nozzle 106g, which is connected to the first air guide cavity 106e. The top and bottom surfaces of the first clamp 101 are fixedly connected with a second nozzle 101c, which is connected to the first air guide cavity 106e. When the airflow passes through the first air guide cavity 106e and the second air guide cavity 101a, the airflow is sprayed onto the patient's head through the first nozzle 106g and the second nozzle 101c, thereby blowing air to cool the user.

[0054] In summary, the fan 106f is used to conveniently transport external air to the interior of the first air guide cavity 106e, and then the airflow is transported to the interior of the second air guide cavity 101a through the air guide tube 101b. As the airflow continuously passes through the first air guide cavity 106e and the second air guide cavity 101a, the neck limiter 106 and the first clamp 101 are cooled, and then the airflow is sprayed on the patient's head through the first nozzle 106g and the second nozzle 101c, thereby blowing air to cool the user.
