[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figure 1-Figure 2 The utility model provides an embodiment: a campus security monitoring alarm device, comprising: a mounting bracket 1, an adjustable angle adjustment seat 2 is installed on the right end of the mounting bracket 1, the adjustment seat 2 has two movable joints, and the joints are connected by a bolt structure. After adjusting the angle of the adjustment seat 2, the bolts can be tightened to fix the adjustment seat 2, and a monitoring alarm 3 is installed on the top of the adjustment seat 2. The installation angle of the monitoring alarm 3 can be adjusted according to the adjustment seat 2. It is only necessary to adjust the angle of the adjustment seat 2, and the monitoring alarm 3 can be fixed to the adjustment seat 2 by the bolt structure. Interfaces 4 are provided on both sides of the bottom of the monitoring alarm 3, and terminal plugs 6 are inserted inside the interface 4. The terminal plugs 6 provide a channel for power and data transmission for the operation of the monitoring alarm 3, and the terminal plugs 6 and the circuit structure connected to the terminal plugs 6 provide effective power support for the operation of the monitoring alarm 3.

[0036] Reference Figures 1-4The limiting component is used to limit the terminal plug 6 to prevent it from separating from the interface 4. The limiting component includes a ring-shaped socket 5. The top of the ring-shaped socket 5 is fixedly connected to the bottom of the interface 4, and the inner wall of the ring-shaped socket 5 is sleeved on the outside of the terminal plug 6. The terminal plug 6 passes through the inside of the ring-shaped socket 5 and enters the interface 4. The ring-shaped socket 5 can provide a layer of protection for the connection between the terminal plug 6 and the interface 4 to ensure the stability of the connection. Four sliding grooves 7 are opened inside the ring-shaped socket 5. A limiting block 8 is slidably connected inside each sliding groove 7. An elastic rope 9 is fixedly connected between each limiting block 8 and the inner wall of the ring-shaped socket 5. Through the elastic properties of the elastic rope 9 itself, a force toward the outside of the sliding groove 7 can be applied to the limiting block 8 at all times, pushing the limiting block 8 tightly out of the sliding groove 7 and stuck at the bottom of the terminal plug 6, preventing the terminal plug 6 from accidentally falling off from the interface 4. The bottom of the limit block 8 is fixedly connected to a triangular block 10, and the bottom of the annular socket 5 is installed with a driving assembly for driving the triangular block 10 to move; the driving assembly includes a toggle ring 11, the top of the toggle ring 11 is rotatably connected to the bottom of the annular socket 5, and the top edge of the toggle ring 11 is fixedly connected to four wedge blocks 12, each wedge block 12 abuts against the corresponding triangular block 10 to drive the triangular block 10 to move inside the slide groove 7. When the toggle ring 11 rotates, the wedge block 12 will cooperate with the inclined surface structure on the side and the inclined surface structure on the side of the triangular block 10 through the action of force, so that the triangular block 10 can be driven by the movable wedge block 12 to move toward the inside of the slide groove 7, and then the limit block 8 at the top of the triangular block 10 is completely driven and retracted into the inside of the slide groove 7, opening the channel between the annular socket 5 and the toggle ring 11, making it convenient for the terminal plug 6 to enter and exit. The outer side of the wedge block 12 is arranged inside the slide groove 7, and the outer side of the limit block 8 is slidably connected to the inside of the slide groove 7. The wedge block 12 is restricted by the slide groove 7 to ensure that the wedge block 12 can only move within a fixed range, thereby preventing the toggle ring 11 from rotating too much.

[0037] Reference Figure 5-Figure 6The emergency backup assembly is used to provide backup circuit support when the main circuit of the monitoring alarm device is damaged. It is installed in the receiving cavity 13 defined within the mounting bracket 1. By installing the emergency backup assembly within the receiving cavity 13, the mounting bracket 1 effectively protects the assembly from damage and erosion caused by natural weather or disasters such as rain. The emergency backup assembly includes a fixed foam 14 and an elastic block 16. The outer side of the fixed foam 14 is fixedly connected to the inner wall of the receiving cavity 13. The interior of the fixed foam 14 is plugged into a backup connector 15. By inserting the terminal structure at the end of the backup connector 15 into the fixed foam 14, the terminal structure of the backup connector 15 can be effectively sealed and preserved, preventing it from rusting and affecting its use due to long-term idleness. The outer side of the elastic block 16 abuts against the middle side of the inner wall of the receiving cavity 13, and a pull ring 17 is fixedly connected to the side of the elastic block 16 away from the fixed foam 14. The elastic block 16 with its elastic structure cooperates with the inner wall of the receiving cavity 13 to effectively fix the elastic block 16 within the receiving cavity 13 and act as a partition, ensuring that the space where the spare connector 15 is located is sealed, further protecting the spare connector 15 from corrosion and increasing the life of the spare connector 15. A main data cable 20 is provided at the bottom of the terminal plug 6, and a spare data cable 21 is provided to the right side of the spare connector 15. Cable holes 18 are provided on the upper and lower sides of the interior of the mounting bracket 1. The main data cable 20 and the spare data cable 21 are both inserted into the cable holes 18. The cable holes 18 that pass through the interior of the receiving cavity 13 can effectively arrange and organize the main data cable 20 and the spare data cable 21. A tie frame 19 is fixedly connected to the bottom of the mounting bracket 1. It is located below the cable routing hole 18. The main data cable 20 and the backup data cable 21 are secured to the tie frame 19 via a binding structure, thereby restraining and organizing the wire harness and ensuring its aesthetics. The outer side of the backup data cable 21 passes through the bottom of the elastic block 16, and there is an interference fit between the outer side of the backup data cable 21 and the elastic block 16. The backup data cable 21 and the notch at the bottom of the elastic block 16 cooperate, allowing the backup data cable 21 to pass through the elastic block 16 while ensuring a tight seal at the bottom of the elastic block 16.

[0038] Working principle: The campus security monitoring alarm device is installed at a designated location on campus by using bolts and the mounting holes at the end of the mounting bracket 1. When assembling the circuit, the worker passes the main data line 20 at the bottom of the terminal plug 6 for power supply and information transmission through the cable hole 18, and then connects the end of the backup data line 21 to the power supply equipment. Then, the terminal plug 6 is inserted upward from the bottom of the toggle ring 11. At this time, the synchronous rotation of the toggle ring 11 drives the wedge block 12 at its top to move. When the wedge block 12 moves inside the chute 7, it pushes the triangular block 10 abutting against it. The inclined surfaces on the two structures cooperate with each other, so that when the toggle ring 11 rotates, it can drive the triangular block 10 to move inside the chute 7 through the wedge block 12, and then drive the upper limit block 8 to move toward the inside of the chute 7 through the triangular block 10. When the limit block 8 moves, it stretches the elastic rope 9. At this time, the channel between the toggle ring 11 and the annular socket 5 is opened. Push the terminal plug 6 upward until the terminal at the top of the terminal plug 6 is fully inserted into the interface 4. At this time, the monitoring alarm 3 and the terminal plug 6 are assembled. Then, release the toggle ring 11. The elastic cord 9 will deform under the action of the elastic force and push the limit block 8 outward from the inside of the slide groove 7. At the same time, the limit block 8 will move to reset the toggle ring 11 by pushing the triangular block 10 and the wedge block 12. At this time, the top of the limit block 8 and the bottom step structure of the terminal plug 6 abut against each other, completely confining the terminal plug 6 inside the interface 4.

[0039] When there is a fault in the circuit where one of the terminal plugs 6 is located, the maintenance personnel can extend their fingers into the receiving cavity 13 from the top of the cable hole 18 and hook the pull ring 17 with their fingers. Then, they pull the pull ring 17 to drive the elastic block 16 connected to it to move. Since the pull ring 17 is located on the side of the elastic block 16, the elastic block 16 will be loosened laterally from the inside of the receiving cavity 13. When the elastic block 16 falls off from the inside of the receiving cavity 13, the space inside the receiving cavity 13 will be opened, and the maintenance personnel can hook and pull the spare data line 21 so that the terminal on the spare connector 15 can be opened. It can be pulled out from the inside of the fixed foam 14, and then the spare connector 15 is continued to be pulled to the position of the cable hole 18, and the spare connector 15 is taken out upward from the inside of the cable hole 18, and then the above installation operation is repeated, and the spare connector 15 is plugged into the inside of an interface 4 with a damaged circuit to be used as an emergency backup line. This ensures that when the main circuit of the campus safety monitoring and alarm device fails again, the spare connector 15 can be used to ensure that the device can be put into work quickly, and there is no need to wait until the main circuit is maintained before it can be put into use, so that the device can further improve the monitoring and alarm functions of campus safety.
