Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1 The utility model provides an embodiment: a campus monitoring machine based on the Internet of Things, including a fixed frame 1, the bottom end of the fixed frame 1 can be provided with an automatic moving component, including a drive, wheels, connecting rods and other structures, which are used to facilitate the movement of the monitoring device. This is a simple prior art means in this field and will not be described in detail here. A linear screw 2 is arranged inside the fixed frame 1, and the linear screw 2 includes: a motor and a screw, the screw is rotatably connected to the inside of the fixed frame 1, the bottom output end of the motor passes through the fixed frame 1, and the bottom output end of the motor is fixedly connected to the upper end of the screw, and when the motor is started, the screw can be driven to rotate, fixed A limit plate 3 is slidably connected to the left side of the frame 1, and a slide groove is provided on the left side surface of the fixed frame 1. The limit plate 3 is slidably connected to the fixed frame 1 through the slide groove. A monitor 4 is fixedly connected to the upper right end of the limit plate 3. The left end of the monitor 4 is threadedly connected to the screw rod. When the motor is started, the monitor 4 can perform linear motion in the up and down directions under the limit of the limit plate 3, and then the height of the monitor 4 can be adjusted, and then the monitoring height is adjusted. A buzzer is set at the upper end of the monitor 4. When a biological approach is detected, the buzzer will be triggered to emit a red light buzzing warning, so as to carry out campus monitoring. A support component is set at the bottom of the monitor 4.
[0034] Reference Figure 1-Figure 3 The support assembly includes: a support plate 501 and a limit block 505. The support plate 501 is arranged below the monitor 4. The upper surface of the support plate 501 fits with the bottom surface of the monitor 4. The support plate 501 can support the bottom of the monitor 4. The bottom surface of the support plate 501 is fixedly connected with an inclined plate 502. An L-shaped through groove 503 is provided on the upper surface of the inclined plate 502. The screw rod can enter the interior of the inclined plate 502 through the L-shaped through groove 503. A threaded sleeve 504 is fixedly connected to the right inner wall surface of the L-shaped through groove 503. The left end of the threaded sleeve 504 is arranged in an open structure. The threaded sleeve 504 is threadedly connected to the screw rod. When the inclined plate 502 moves to the right, the screw rod will leave the connection with the threaded sleeve 504, and then the screw rod can leave the interior of the inclined plate 502 through the L-shaped through groove 503.
[0035] The left end of the inclined plate 502 is in contact with the right side surface of the limit plate 3. At this time, a triangular support structure is formed between the limit plate 3, the inclined plate 502, the support plate 501 and the monitor 4. The inclined plate 502 and the support plate 501 can support the bottom end of the monitor 4 at this time, reducing the situation where the monitor 4 is tilted relative to the limit plate 3 due to its own gravity, which will not only affect the monitoring range of the monitor 4, but also affect the threaded connection between the monitor 4 and the screw rod, causing the monitor 4 to be stuck and unable to move. When the screw rod rotates, it can drive the inclined plate 502 and the support plate 501 to move synchronously with the monitor 4 under the limit of the limit plate 3, so that the self-gravity of the inclined plate 502 and the support plate 501 is partially borne by the screw rod, reducing the influence of the self-gravity of the inclined plate 502 and the support plate 501 on the support effect, improving the support service life of the support assembly, and avoiding the inclined plate 502 and the support plate 501 The self-gravity is completely borne by themselves, which affects the service life of the support assembly.
[0036] The limit block 505 is fixedly connected to the left end of the inclined plate 502, and a mounting groove 506 is provided on the bottom surface of the limit block 505. A spring 507 is fixedly connected to the inner top surface of the mounting groove 506, and a clamping block 508 is fixedly connected to the bottom end of the spring 507. When the clamping block 508 moves upward, it will enter the interior of the mounting groove 506 and squeeze the spring 507, so that the spring 507 is compressed to generate elastic potential energy. The outer wall of the clamping block 508 is in contact with the inner wall of the mounting groove 506, and the bottom end of the left side surface of the clamping block 508 is rounded. A limit groove 509 is provided on the bottom end of the right side surface of the limit plate 3, and the limit block 505 is plugged into the inside of the limit groove 509.
[0037] When the limit block 505 is inserted into the limit groove 509, the inner wall of the limit groove 509 will squeeze the block 508 along the bottom arc surface of the clamping block 508, so that the clamping block 508 moves upward and enters the interior of the installation groove 506. The inner bottom surface of the limit groove 509 is provided with a clamping groove 510, and the bottom end of the clamping block 508 is clamped with the interior of the clamping groove 510. When the limit block 505 completely enters the limit groove 509, the clamping block 508 will move downward into the interior of the clamping groove 510 under the elastic potential energy of the spring 507. At this time, the limit block 505 and the inclined plate 506 can be clamped. 2 for card connection installation, a moving block 511 is arranged inside the card slot 510, and a moving rod 512 is fixedly connected to the bottom end of the moving block 511, and the bottom end of the moving rod 512 passes through the limit plate 3. When the inclined plate 502 and the support plate 501 are bent during long-term use, which affects the supporting effect on the monitor 4, the moving rod 512 can be moved upward to drive the moving block 511 to move upward synchronously to squeeze the card block 508 out of the card slot 510, and contact the card connection and fixation of the limit block 505, so that the inclined plate 502 and the support plate 501 can be quickly disassembled and replaced, and the operation is simple.
[0038] Reference Figure 1-Figure 4 The upper end of the monitor 4 is fixedly connected with a placement box 601, and the inner bottom surface of the placement box 601 is provided with a lower groove 602, the center of the lower groove 602 is depressed downward, and the inclination angles of the left and right ends of the lower groove 602 are small. When the monitor 4 is slightly tilted, it will drive the moving ball 603 to move. The inside of the placement box 601 is provided with a moving ball 603. When the monitor 4 is in a horizontal placement state, the moving ball 603 will be at the center of the lower groove 602 under the action of the inclined surface of the lower groove 602. The right inner wall surface of the placement box 601 is fixedly connected with a button 604, and the button There is an electrical connection between button 604 and the buzzer on the monitor 4. When the moving ball 603 moves to the right due to the tilt of the monitor 4, the button 604 will be squeezed and pressed. At this time, the button 604 will send a signal to the buzzer to remind the staff that the supporting component is damaged due to long-term use and needs to be replaced in time. A glass plate 605 is fixedly connected to the top of the placement box 601. The staff can observe the position of the moving ball 603 through the glass plate 605, and then judge whether the monitor 4 is in a balanced state after adjustment.
[0039] Working principle: Move the screw rod through the L-shaped through slot 503 into the interior of the inclined plate 502, and then fully insert the limit block 505 into the interior of the limit slot 509 to complete the clamping installation of the inclined plate 502 and the support plate 501. At this time, the threaded sleeve 504 will be threadedly connected with the screw rod, so that the screw rod bears part of the weight of the inclined plate 502 and the support plate 501, extending the service life of the support assembly. After the installation is completed, the support plate 501 will fit with the bottom surface of the monitor 4, through the triangle formed by the limit plate 3, the inclined plate 502 and the support plate 501. The stable structure provides limited support for the bottom end of the monitor 4, thereby extending the stable use time of the monitor 4 and reducing the downward tilt of the monitor 4 due to its own gravity. When the monitor 4 is cleaned, the moving ball 603 will move toward the button 604 and press the button 604, reminding the staff to replace the inclined plate 502 and the support plate 501. At this time, the staff can push the moving rod 512 upward to release the clamping fixation of the inclined plate 502, and quickly replace the inclined plate 502 and the support plate 501, which is easy to operate.
