Description

Technical Field

[0001] The utility model relates to the field of life detectors, in particular to an audio and video life detector. Background Art

[0002] The life detector is a safety and life-saving system recently launched by Super Vision Safety Systems in the United States in 2005. David Seth, a famous physicist and Ph.D. from MIT, creatively applied radar ultra-wideband technology to the field of safety and life-saving, thus bringing a revolutionary new technology to the field. It is suitable for fire fighting, municipal administration, mine rescue and other agencies to use for rescue of ruins caused by earthquakes, collapses and building collapses. The audio and video life detector does not need to work uninterruptedly, but needs to be turned on intermittently for detection when needed.

[0003] According to a Chinese patent with publication number CN219322730U, an audio and video life detector is disclosed. This utility model is different from a traditional audio and video life detector. The audio and video life detector can be put on the wrist for carrying when it is not needed to work. It is convenient and simple to wear, thereby freeing the operator's hands to do other things, further reflecting the portability and practicality of the audio and video life detector.

[0004] Regarding the above-mentioned disclosed patent content, a display screen is provided so that the display screen can display information. However, when the life detector is carried and accidentally dropped to the ground, since the display screen is not protected, when one side of the display screen contacts the ground face down, the display screen will directly collide with the ground, causing damage to the display screen, thereby reducing the protection effect of the life detector and reducing the service life of the life detector. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an audio and video life detector to solve the technical problem that it is inconvenient to shield and protect the display screen on the detector when the life detector is not in use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an audio and video life detector, comprising a life detector body, a protective component is provided above the outer surface of the life detector body, and the protective component comprises a cavity opened inside the life detector body, a first rotating shaft and a second rotating shaft are respectively provided inside the cavity through bearings, a first gear is sleeved on the outer wall of the first rotating shaft, and a second gear is sleeved on the outer wall of the second rotating shaft, one end of the first rotating shaft extends to the outer surface of the life detector body and is connected to a first protective plate, one end of the second rotating shaft extends to the outer surface of the life detector body and is connected to a second protective plate, and a magnetic suction block is provided on one side of the bottom of the second protective plate and one side of the bottom of the first protective plate.

[0007] By adopting the above technical solution, when the first protective plate and the second protective plate are rotated and reset, the first protective plate and the second protective plate will fit together, and the two magnetic blocks will be adsorbed together to prevent the first protective plate and the second protective plate from rotating at will.

[0008] Furthermore, the outer walls of the first rotating shaft and the second rotating shaft are both sleeved with torsion springs, and one end of the torsion spring is connected to the inner wall of the cavity.

[0009] By adopting the above technical solution, the torsion spring is provided to facilitate the subsequent driving of the first rotating shaft and the second rotating shaft to return to rotation, thereby enabling the first protective plate and the second protective plate to be quickly reset.

[0010] Furthermore, a groove is provided on one side of the top of the first protective plate, and a spring is fixed inside the groove, and a clamping column is connected to the top of the spring.

[0011] By adopting the above technical solution, when the clamping column moves into the groove, the spring can be squeezed, so that the spring is compressed, which facilitates the subsequent pushing of the clamping column to reset and move.

[0012] Furthermore, a movable shaft is provided on one side of the top of the second protective plate, and a limit plate is sleeved on the outer wall of the movable shaft, and a clamping hole is opened on the limit plate.

[0013] By adopting the above technical solution, the limiting plate can be rotated through the movable shaft, and when the limiting plate rotates, it will drive the clamping hole to rotate, so that the clamping hole and the clamping column can be aligned.

[0014] Furthermore, the clamping column is adapted to the clamping hole, and the top end of the clamping column is arc-shaped.

[0015] By adopting the above technical solution, when the clamping column moves into the clamping hole, the limit plate can be limited to prevent the limit plate from rotating at will.

[0016] Furthermore, the first gear is meshed with the second gear, and the diameter of the first gear is the same as the diameter of the second gear.

[0017] By adopting the above technical solution, when the first gear rotates, it will drive the second gear to rotate in the opposite direction, so that the second rotating shaft rotates, thereby allowing the first protective plate and the second protective plate to rotate simultaneously.

[0018] Furthermore, a display screen is provided at a middle position of the outer surface of the life detector body, and buttons are provided on both sides of the outer surface of the life detector body.

[0019] By adopting the above technical solution, the display screen can display the detection information, making it convenient for the user to understand the detection information through the display screen.

[0020] Furthermore, the first protection plate is rotatably connected to the life detector body via a first rotating shaft, and the second protection plate is rotatably connected to the life detector body via a second rotating shaft.

[0021] By adopting the above technical solution, the arrangement of the first rotating shaft facilitates the rotation of the first protective plate, and the arrangement of the second rotating shaft facilitates the rotation of the second protective plate.

[0022] Furthermore, the outer surface of the first protective plate and the outer surface of the second protective plate are both provided with protrusions, and the outer walls of the protrusions are sleeved with anti-slip sleeves.

[0023] By adopting the above technical solution, when the first protective plate needs to be rotated, the user can push the first protective plate to rotate through the protrusion, so that the magnetic blocks on the first protective plate and the second protective plate are separated.

[0024] Furthermore, the sizes of the first protective plate and the second protective plate are both larger than half the size of the display screen.

[0025] By adopting the above technical solution, the first protective plate and the second protective plate can shield the display screen after being reset, thereby protecting the display screen.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with a protection component. When the life detector needs to be used, the user can push the first protection plate to rotate counterclockwise through the protrusion, so that the first shaft drives the first gear to rotate counterclockwise, and the first gear drives the second gear to rotate clockwise, and drives the second shaft to rotate clockwise, and then drives the second protection plate to rotate clockwise, so that the first protection plate and the second protection plate no longer block the display screen, so that the display screen can be used, and then the clamping column is clamped into the clamping hole to limit the position of the limit plate, and then the first protection plate and the second protection plate are limited to prevent the first protection plate and the second protection plate from rotating and resetting at will. When the life detector is not needed, When the user presses the card column, the card column is moved out of the card hole. At this time, the torsion spring is reset and drives the first rotating shaft and the second rotating shaft to reset and rotate, and then drives the first protective plate and the second protective plate to rotate and reset. When resetting, the first protective plate and the second protective plate will fit together. At this time, the two magnetic blocks will be adsorbed together to prevent the first protective plate and the second protective plate from rotating at will. In this way, the display screen and the buttons can be shielded by the first protective plate and the second protective plate to protect the display screen and the buttons, thereby preventing the display screen from colliding with external objects when the life detector body falls to the ground during carrying and causing damage, thereby increasing the service life of the display screen.

[0045] When the life detector is not needed, the user can press the card column 415 to move the card column 415 out of the card hole 416. At this time, the torsion spring 409 is reset and drives the first rotating shaft 407 and the second rotating shaft 408 to reset and rotate, and then drives the first protective plate 401 and the second protective plate 402 to rotate and reset. When resetting, the first protective plate 401 and the second protective plate 402 will fit together. At this time, the two magnetic blocks 410 will be adsorbed together to prevent the first protective plate 401 and the second protective plate 402 from rotating at will. In this way, the display screen 2 and the button 3 can be shielded by the first protective plate 401 and the second protective plate 402 to protect the display screen 2 and the button 3.
