Description

Technical Field

[0001] This utility model belongs to the field of elevator monitoring, specifically an in-elevator monitoring device. Background Technology

[0002] A camera is a video input device, also known as a computer camera or computer eye. It is widely used in video conferencing, telemedicine, real-time monitoring, digital imaging, audio-visual processing, and many other fields. The working principle of a camera is relatively simple. It mainly captures the light of the subject through the lens, and then focuses this light onto the camera's image sensor. The image sensor then converts the optical image into an electrical signal. After processing such as noise reduction and analog-to-digital conversion, the electrical signal is sent to the processor for decoding, and finally converted into an image that we can see.

[0003] Chinese utility model patent CN221295792U discloses an elevator IoT monitoring camera, including a threaded hollow tube. Both ends of the threaded hollow tube are provided with threaded rods, and the front ends of both sets of threaded rods are provided with rotating rings. The front ends of both sets of rotating rings are provided with pads, and the outer walls of the pads are provided with anti-slip rubber strips. The outer wall of the threaded hollow tube is provided with two sets of connecting rings. This utility model, through the threaded hollow tube, threaded rods, rotating rings, pads, and mounting plate, allows the camera to be easily installed inside the elevator without drilling holes or installing fixing screws. The installation process is very simple and easy. Disassembly is also very convenient when a malfunction occurs and repairs are needed, making installation and maintenance processes faster and more convenient.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the camera angle of the IoT surveillance camera is inconvenient to adjust during use, making it inconvenient to film blind spots inside the elevator.

[0005] To address the problems raised in the background art, those skilled in the art have proposed an elevator in-flight monitoring device. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an elevator monitoring device to solve the problem that existing IoT monitoring cameras are inconvenient to adjust their camera angles, making it difficult to monitor blind spots inside elevators.

[0007] An elevator monitoring device includes a mounting frame, an arc-shaped plate fixedly connected to the lower end of the mounting frame, a through groove opened in the arc-shaped plate, a mounting frame slidably connected to the surface of the arc-shaped plate, a camera body disposed below the mounting frame, and a mounting plate disposed above the mounting frame. The mounting frame has a "U" shaped structure. The mounting frame is provided with an adjustment component for adjusting the position of the mounting frame. The mounting frame is provided with a mounting component for mounting the camera body. The mounting frame is provided with a limiting component for limiting the camera body to the mounting plate.

[0008] The adjustment assembly includes a mounting slot formed in the mounting frame, a rotating rod rotatably connected in the mounting slot, and a connecting rod fixedly fitted onto the surface of the rotating rod. The lower end of the connecting rod is fixedly connected to the upper end of the mounting frame.

[0009] Preferably, a first helical bevel gear is fixedly mounted on the surface of the rotating rod, and a first servo motor is mounted on one end of the mounting bracket. The first servo motor includes a mounting shaft mounted on its output end and a second helical bevel gear fixedly connected to one end of the mounting shaft. The second helical bevel gear meshes with the first helical bevel gear.

[0010] Preferably, a limiting rod is slidably connected within the through groove, and the limiting rod is fixedly connected within the mounting frame.

[0011] Preferably, the limiting component includes a rotating column rotatably connected to the upper end of the mounting bracket, a toothed groove formed on the side of the rotating column, a second servo motor mounted on the upper end of the mounting bracket, and a gear mounted on the output end of the second servo motor. The gear meshes with the toothed groove, the upper end of the rotating column is rotatably connected to the lower surface of the mounting plate, and the mounting plate has a plurality of symmetrically arranged mounting holes.

[0012] With the above technical solution, the application scenario of this device is to facilitate the adjustment of the camera angle of the camera body. Specifically, the mounting plate is installed on the top of the elevator car, and the first and second servo motors are powered on. The output ends of the first and second servo motors rotate periodically, rotating half a turn and then rotating in the opposite direction. The upper end of the connecting rod matches the center of the arc plate. That is, when the output end of the first servo motor rotates, it can drive the rotating rod to rotate using the second and first helical bevel gears. This can achieve the effect of adjusting the position of the mounting frame and the camera body on it, making it convenient for the camera body to shoot at different positions. Furthermore, the rotation of the output end of the second servo motor can drive the rotating column to rotate using the gears, which can drive the mounting bracket to rotate below the mounting plate. Compared with existing IoT monitoring cameras, this device can expand the shooting range of the camera body, making it convenient to shoot blind spots in the elevator car.

[0013] Preferably, the mounting component includes a limiting groove formed at the lower end of the mounting frame, a limiting block slidably connected in the limiting groove, and an insert rod slidably connected in the limiting block and the mounting frame. The limiting groove and the limiting block are both "T" shaped structures, and the camera body is mounted at the lower end of the limiting block.

[0014] Preferably, a pull block is fixedly connected to one end of the insertion rod, and a spring is sleeved on the surface of the insertion rod. One end of the spring is fixedly connected to one side of the mounting frame, and the other end of the spring is fixedly connected to one side of the pull block.

[0015] With the above technical solution, when in use, the plug can be pulled out from the limiting block by pulling the pull block, thereby removing the restriction of the plug on the limiting block. Then, the limiting block on the camera body can be slid out from the limiting groove, thereby achieving the effect of convenient disassembly of the camera body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model connects the first and second servo motors to the power supply. The output ends of both the first and second servo motors rotate periodically, rotating half a turn and then rotating in the opposite direction. The upper end of the connecting rod matches the center of the arc plate. That is, when the output end of the first servo motor rotates, it can drive the rotating rod to rotate using the second and first helical bevel gears. This can achieve the effect of adjusting the position of the mounting frame and the camera body on it, making it convenient for the camera body to shoot at different positions. Furthermore, the rotation of the output end of the second servo motor can drive the rotating column to rotate using the gears, thereby driving the mounting bracket to rotate below the mounting plate. Compared with existing IoT monitoring cameras, this device can expand the shooting range of the camera body, making it convenient to shoot blind spots inside the elevator car.

[0018] 2. This utility model allows the insertion rod to be pulled out of the limiting block by pulling the pull block, thereby removing the restriction of the limiting block by the insertion rod. Then, the limiting block on the camera body can be slid out of the limiting groove, thereby achieving the effect of convenient disassembly of the camera body. Attached Figure Description

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides an elevator monitoring device, including a mounting frame 1, an arc-shaped plate 2 fixedly connected to the lower end of the mounting frame 1, a through groove 201 opened in the arc-shaped plate 2, a mounting frame 202 slidably connected to the surface of the arc-shaped plate 2, a camera body 3 disposed below the mounting frame 202, and a mounting plate 4 disposed above the mounting frame 1. The mounting frame 1 has a "U" shaped structure. The mounting frame 1 is provided with an adjustment component for adjusting the position of the mounting frame 202. The mounting frame 202 is provided with a mounting component for mounting the camera body 3. The mounting frame 1 is provided with a limiting component for limiting it on the mounting plate 4.

[0028] The adjustment assembly includes a mounting slot 101 formed in the mounting frame 1, a rotating rod 102 rotatably connected in the mounting slot 101, and a connecting rod 103 fixedly fitted on the surface of the rotating rod 102.

[0029] The surface of the rotating rod 102 is fixedly fitted with a first helical bevel gear 104, and a first servo motor 105 is mounted on one end of the mounting bracket 1. The first servo motor 105 includes a mounting shaft 106 mounted on its output end and a second helical bevel gear 107 fixedly connected to one end of the mounting shaft 106. The second helical bevel gear 107 meshes with the first helical bevel gear 104.

[0030] A limiting rod 203 is slidably connected inside the through groove 201, and the limiting rod 203 is fixedly connected inside the mounting frame 202.

[0031] The limiting component includes a rotating column 401 rotatably connected to the upper end of the mounting frame 1, a toothed groove 402 formed on the side of the rotating column 401, a second servo motor 403 mounted on the upper end of the mounting frame 1, and a gear 404 mounted on the output end of the second servo motor 403. The gear 404 meshes with the toothed groove 402. The upper end of the rotating column 401 is rotatably connected to the lower surface of the mounting plate 4. The mounting plate 4 has a plurality of symmetrically arranged mounting holes.

[0032] As can be seen from the above, the application scenario of this device is to facilitate the adjustment of the camera angle of the camera body 3. Specifically, the mounting plate 4 is installed on the top of the elevator car, and the first servo motor 105 and the second servo motor 403 are powered on. The output ends of both the first servo motor 105 and the second servo motor 403 rotate periodically. The output ends of the first servo motor 105 and the second servo motor 403 rotate half a turn and then rotate in the opposite direction. The upper end of the connecting rod 103 is aligned with the center of the arc plate 2. That is, when the output end of the first servo motor 105 rotates... The second helical bevel gear 107 and the first helical bevel gear 104 can be used to drive the rotating rod 102 to rotate, thereby adjusting the position of the mounting frame 202 and the camera body 3 on it, making it convenient for the camera body 3 to shoot at different positions. Furthermore, the rotation of the output end of the second servo motor 403 can drive the rotating column 401 to rotate through the gear 404, thereby driving the mounting bracket 1 to rotate under the mounting plate 4.

Then, the limiting block 205 on the camera body 3 can be slid out from the limiting groove 204, thereby achieving the effect of convenient disassembly of the camera body 3.
