Description

Technical Field

[0001] This utility model relates to the field of recording device technology, and in particular to a sociological survey recording device. Background Technology

[0002] The main function of sociological survey recording devices is to record survey data, help sociologists conduct public opinion surveys better, preserve and organize sociological data, and provide more accurate basic information for academic research. At the same time, such devices also help improve the standardization and systematicness of sociological surveys and promote the scientific development of sociological research.

[0003] A search revealed a sociological survey recording device disclosed in utility model publication CN216253033U, but it still has some shortcomings in practical use:

[0004] 1. The device is equipped with a pen slot, but in actual use, after the pen is placed in the pen slot, the pen slot does not have a mechanism to restrain the pen. When the recorder and the cover cannot be closed, the pen will fall out.

[0005] 2. Paper writing is often used when conducting sociological surveys. Although this device holds the recording paper, the paper is not fixed in place and is easy to fall off, making it inconvenient to use. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the pen falling off when the recorder and cover cannot be closed, and the paper falling off easily even when it is placed, which makes the whole process inconvenient. Therefore, this invention proposes a sociological survey recording device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A sociological survey recording device includes a recorder and a cover plate. A plurality of connecting sleeves are fixedly connected to one side of the recorder. A plurality of irregular shafts are fixedly connected to one side of the cover plate via connecting shafts, and the connecting sleeves are sleeved on the irregular shafts. A clamping plate is provided on one side of the cover plate, and the clamping plate and the cover plate can clamp paper. A pen groove is provided on one side of the cover plate.

[0009] In one possible design, a contact plate is slidably connected inside the connecting sleeve. The connecting sleeve has a cylindrical groove, and the contact plate extends into the cylindrical groove. One side of the contact plate and one side of the inner wall of the connecting sleeve are provided with spring plates. The two sides of the spring plates are respectively in contact with the inner walls of the contact plate and the connecting sleeve. The irregular shaft passes through the connecting sleeve through a rotating connecting shaft and rotates in the cylindrical groove, contacting the contact plate.

[0010] In one possible design, sleeves are fixedly connected to both ends of the clamping plate, two limiting shafts are fixedly connected inside the cover plate, and the sleeves are slidably sleeved on the outer walls of the limiting shafts. A tension spring is sleeved on the outer wall of the limiting shaft, and the sleeves are sleeved on the outer wall of the tension spring. One end of the tension spring is fixedly connected to one side of the inner wall of the cover plate, and the other end of the tension spring is fixedly connected to the inner wall of the sleeve.

[0011] In one possible design, a limiting plate is provided on one side of the pen slot, and sliders are fixedly connected to both ends of the limiting plate. Two springs are fixedly connected inside the cover plate, and the top of the springs is fixedly connected to the bottom of the sliders, and the sliders slide inside the cover plate.

[0012] In one possible design, magnets are fixedly connected to the sides of the recorder and the cover plate that are in contact with each other, and the two magnets can be magnetically attracted to each other.

[0013] In one possible design, a handset is fixedly mounted on the top of the recorder, a first control panel is provided on one side of the cover, a second control panel is provided on one side of the recorder, a PLC controller is installed inside the recorder, and the PLC controller is electrically connected to the second control panel and the first control panel.

[0014] In this application, the recorder and the cover can be magnetically attracted by two magnets, while the cylindrical groove and the abutment plate can form abutment, limiting the cylindrical groove. During use, recording can be done via the earpiece, and filming can be done via the camera on one side of the recorder. Simple recording and video recording operations can be performed via the first control screen. Opening the cover releases the magnetic attraction between the two first control screens. Simultaneously, the irregular shaft rotates within the connecting sleeve. The irregular shaft forms a contact with the abutment plate through a parallel surface. During rotation, the irregular shaft pushes the abutment plate through its arc angle, causing the spring sheet to unfold and move out of position. When the arc angle disengages from contact with the abutment plate, the irregular shaft... The curved surface of the shaft pushes the contact plate, allowing the shaft to rotate freely. This allows the cover to open freely on one side of the recorder. The second control screen on the recorder allows for detailed operation of the earpiece and camera, as well as related investigation recording. The pen placed in the pen slot can be removed by pressing the limiting plate. The sliders at both ends of the limiting plate compress the spring, allowing the pen to be used for writing. At the same time, the clamping plate and the cover plate work together to hold the paper. The clamping plate and the cover plate are connected by a sleeve on the limiting shaft, and a tension spring creates tension between the clamping plate and the cover plate, holding the paper. Pulling the clamping plate removes the written paper.

[0015] Beneficial effects: In this utility model, the sociological survey recording device, through the cooperation of the clamping plate and the cover plate, as well as the tension design of the sleeve, the limiting shaft and the tension spring, can firmly clamp the paper and prevent the paper from moving or falling off during the writing process. At the same time, the design of the pen slot, the limiting plate, the slider and the spring allows the user to easily take out and put back the pen, further improving the convenience of use.

[0016] In this utility model, the sociological survey recording device uses the magnetic attraction design of two magnets between the recorder and the cover plate, as well as the ingenious design of the connecting shaft, the irregular shaft, the connecting sleeve, the cylindrical groove and the abutment plate, to make the closure between the recorder and the cover plate more secure. At the same time, the arc design of the irregular shaft allows the abutment plate to be pushed smoothly during rotation and to be opened by the spring plate to make way, ensuring the smoothness and stability of rotation.

[0017] This invention features a convenient magnetic opening and closing design, an innovative paper clamping and pen limiting mechanism, a flexible rotating structure design, multi-functional recording capabilities, and ease of operation and maintenance, providing users with a more efficient, convenient, and accurate survey recording experience.
