[0001] The utility model relates to the field of behavior collection, in particular to a collection device for collecting videos of teachers and students' behaviors in a classroom. Background Art

[0002] In today's educational research field, in-depth understanding and analysis of the interaction patterns between teachers and students in the classroom, teaching behaviors, and students' learning behaviors are of great significance for improving teaching quality and learning outcomes. With the development of technology, video analysis methods have become an effective tool for educational researchers to obtain classroom behavior data because they can provide rich visual and audio information. Especially in the context of the increasing popularity of digital education and intelligent teaching environments, the use of video acquisition devices to systematically collect and analyze the behaviors of teachers and students in the classroom can provide more in-depth and detailed insights for educational research and teaching practice.

[0003] Video acquisition devices are needed to collect the behaviors of teachers and students in the classroom. Some key schools (high school entrance examination and college entrance examination test sites) have monitoring equipment installed in the classroom, which can be used to collect videos. Some schools do not have monitoring equipment installed in the classroom, and the classroom is generally equipped with a rotatable monitor. This type of monitoring equipment cannot collect data from multiple angles, resulting in poor collection effects. Arranging multiple fixed cameras in the classroom is likely to cause a waste of resources. Therefore, it is urgent to design a video acquisition device that can adjust the angle and has a disassembly and assembly solution. Utility Model Content

[0004] The purpose of the utility model is to provide a collection device for collecting videos of teacher and student behaviors in a classroom. The device is easy to install and disassemble, and the collection angle is easy to adjust. After adjustment, the shooting angle is fixed, so that the teacher and student behaviors at a specific angle can be collected. After disassembly, it can be applied to the next classroom to continue collecting, and the collected teacher and student behaviors are more diverse.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a collection device for collecting videos of teachers and students' behaviors in a classroom, including a mounting seat, to which a camera body is connected via a rotating structure, the camera body is equipped with a lens module, and a switch button is installed on the camera body, and an adhesive block is bonded to the bottom of the mounting seat, and is bonded to the wall through the adhesive block.

[0006] Preferably, a mounting screw hole is provided at the bottom of the mounting seat, and the mounting screw hole is fastened with a bolt to the bracket or the extension block.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model. Example 1

[0023] like Figure 1 and Figure 3-5 As shown, a collection device for collecting videos of teacher and student behaviors in a classroom includes a mounting base 1, to which a camera body 5 is connected via a rotating structure, a lens module 6 is mounted on the camera body 5, and a switch button 8 is mounted on the camera body 5, an adhesive block 11 is bonded to the bottom of the mounting base 1, and the mounting base 1 is bonded to the wall via the adhesive block 11, a mounting screw hole 12 is provided at the bottom of the mounting base 1, and the mounting screw hole 12 is matched with a bolt to lock with a bracket or an extension block.

[0024] When collecting teacher and student behaviors in the classroom, generally more than 10 classrooms are selected for collection. The collection time for each classroom is more than 2 hours, and generally the collection is for one or two days, that is, the collection device is installed in the morning before the students arrive, and the collection device is removed in the afternoon or evening when all the students leave. Specifically, the collection points are selected according to the number of students in the classroom and the arrangement of seats, generally the front two collection devices and the back two collection devices. In most cases, the installation is carried out through the adhesive block 11, so there is no need to drill holes in the wall. For example, if a speaker is installed in the classroom through a bracket, the camera can be installed on the bracket through the installation screw hole and the bolt. The specific installation of the adhesive block 11 is to tear off a piece of diaphragm 13 first, and then stick the side of the torn diaphragm under the mounting seat 1. In this way, the adhesive block 11 and the mounting block can be fitted together. When the collection device is installed as a whole, tear off the membrane 13 on the other side, and then press the adhesive block 11 against the wall to complete the overall installation. The adhesive block 11 is similar to a commonly used adhesive hook and can withstand a gravity of 2-5kg when pasted on the wall. It is smaller in size than the adhesive block 11 of the present application (most household ones are 100*100mm, while the size of the present application is generally 200*200 or more), so it can bear the overall weight of the collection device. After that, the inclination of the lens module is adjusted by rotating the structure to complete the installation of a collection device. Then, the switch button 8 can be pressed to collect the behavior of teachers and students in the classroom. After each disassembly and assembly, a adhesive block 11 will be replaced. Example 2

[0025] like Figure 1-2 As shown, compared with Example 1, the rotating structure of this embodiment includes a mounting sleeve 2 fixed on the mounting seat 1, the mounting sleeve 2 is sleeved with a rotating shaft 3, the camera body 5 is fixedly sleeved with the rotating shaft 3 through a rotating sleeve 4, and the rotating shaft 3 is locked with the mounting sleeve 2 through a locking bolt 10, and no less than two axial holes 9 are opened on the side of the rotating shaft 3 away from the mounting sleeve 2.

[0026] This embodiment specifically demonstrates the rotation structure, which adjusts the inclination of the box body 5 by loosening the locking bolt 10 to disengage it from the rotating shaft 3, so that the rotating shaft 3 can rotate. When the rotating shaft 3 rotates to the required angle, the locking bolt 10 is tightened again. When tightening the bolt, you can use your fingers or a tool rod to insert it into the shaft hole 9 to prevent the rotating shaft 3 from rotating again when tightening the bolt. Example 3

[0027] like Figure 1 and Figure 6-7As shown, compared with Example 1, the side of the camera body 5 of this embodiment is installed with a removable storage module 7, the rear of the camera body 5 is provided with a stepped opening 16, and the stepped opening 16 is matched with an opening and closing cover 15, a charging interface 17 electrically connected to the battery module in the camera body 5 is provided in the stepped opening 16, and a charger 18 matched with the charging interface 17 is also placed in the stepped opening 16, and the stepped opening 16 is provided with a limit block 19 for limiting the position of the plug and charging connector of the charger 18.

[0028] After completing one collection of teacher and student behaviors in a classroom, the storage module 7 can be removed, and then another storage module can be plugged in for the next collection. In this way, the experimenter can analyze the student behaviors through the removed storage module; the present application places the charging interface 17 and the charger in the stair entrance, which is convenient for carrying the charger and avoids temporarily looking for a charger when charging is needed. It can also be charged and collected on a wall with a socket. You only need to remove the opening and closing cover, plug the charger into the charging interface 17, and then insert the charger plug into the socket to charge.
