[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1 See also Figure 1-6The present embodiment provides an industrial control network monitoring device that is easy to maintain, including a mounting plate 1, a mounting groove 2 is provided in the center of the top surface of the mounting plate 1, and handles 3 are provided on both the front and rear sides of the mounting plate 1, a monitoring alarm 4 is provided in the mounting groove 2, a cable groove 5 is provided at the bottom of the mounting groove 2, and positioning blocks 6 are provided in the center of both sides of the mounting groove 2, and adjustment rods 7 are fixedly connected at both ends of the positioning block 6, and an anti-mistaken collision mechanism 8 is provided in the center of the opposite surface of the positioning block 6 and the handle 3, and two sets of positioning blocks 6 are fixedly connected to the front side of the positioning block 6. Spring 9, one end of the adjusting rod 7 is fixedly connected with a group of tooth blocks 10, and a tooth ring 11 is centrally arranged on the opposite surfaces of two adjacent adjusting rods 7; the anti-accidental collision mechanism 8 includes a fixed block 12, a movable groove 13 is opened inside the fixed block 12, and adjustment grooves 14 are opened on both sides of the movable groove 13, and a movable rod 15 is movably connected inside the movable groove 13, and two limit blocks 16 are fixedly connected to the inner end of the movable rod 15. In order to avoid the loosening of the monitor due to accidental collision and ensure the normal progress of network monitoring, an anti-accidental collision mechanism 8 is provided.

[0030] See also Figure 2 In this embodiment, the lower end of the monitoring alarm 4 is provided with a snap-in groove on both sides, and the positioning block 6 is snap-in-place with the snap-in groove. The monitoring alarm 4 is installed and removed by adjusting the position of the positioning block 6 and the snap-in groove. The snap-in design of the positioning block 6 and the snap-in groove can realize fast and tool-free installation and removal, which greatly saves time and labor costs. By adjusting the position of the positioning block 6 on the installation surface, the installation requirements of different monitoring alarms can be met.

[0031] See also Figure 4 In this embodiment, one end of the positioning spring 9 away from the positioning block 6 is fixedly connected to the inner surface of the mounting plate 1, and the positioning block 6 is reset to engage with the monitoring alarm 4, and the pressure generated by the positioning spring 9 is cooperated to complete the installation of the monitoring alarm 4. The introduction of the positioning spring 9 adds additional stability and reliability to the installation process of the monitoring alarm 4. One end of the positioning spring 9 is fixedly connected to the inner surface of the mounting plate 1, which means that the fixed end of the spring is stable and will not move due to the installation or removal of the monitoring alarm. The other end is connected to the positioning block 6. When the positioning block 6 is separated from the engaging groove of the monitoring alarm 4, the positioning spring 9 will try to pull the positioning block 6 back to its original position (i.e., the position aligned with the engaging groove) due to its elastic potential energy.

[0032] See also Figure 5In this embodiment, the two adjustment rods 7 on the same side are staggered, the toothed ring 11 is meshed with the toothed block 10, and the movement of the positioning block 6 drives the corresponding two adjustment rods 7 to move. The two adjustment rods 7 are located on the same side but are staggered, which helps to achieve more complex mechanical movements without adding extra space. The staggered arrangement can also avoid mutual interference between the two adjustment rods during movement, ensuring smooth transmission.

[0033] See also Figure 5 In this embodiment, the two gear rings 11 are respectively located on both sides of the interior of the mounting plate 1, and the gear rings 11 are movably connected to the mounting plate 1. Under the action of the tooth block 10 and the gear ring 11, another set of positioning blocks 6 and the adjustment rod 7 are synchronously moved in the opposite direction, thereby making the second positioning block 6 synchronously separated from the outside of the monitoring alarm 4. The two gear rings 11 are respectively located on both sides of the interior of the mounting plate 1, which means that they are installed in the space inside the mounting plate to save external space and protect the transmission mechanism from external interference. The gear ring 11 is movably connected to the mounting plate 1, which allows the gear ring to rotate or translate relative to the mounting plate when subjected to external force.

[0034] See also Figure 6 In this embodiment, one side of the positioning block 6 passes through the mounting plate 1 and is fixedly connected to the inner end of the fixed block 12. When the handle 3 is pulled outward, the fixed block 12 drives the positioning block 6 to separate from the clamping groove on the outer side of the monitoring alarm 4 under the action of the limit block 16. One side of the positioning block 6 passes through the mounting plate 1 and is fixedly connected to the inner end of the fixed block 12 located on the inner side of the mounting plate. This connection method ensures that the positioning block 6 can move stably when subjected to external force, and its movement can be transmitted to the fixed block 12. The handle 3 is a component operated by the user, usually located on the outside of the mounting plate, which is convenient for the user to hold and pull. The limit block 16 is a component that plays a limiting or guiding role. It may be installed inside or outside the mounting plate and interact with a part of the fixed block 12 or the handle 3. When the user pulls the handle 3 outward, the limit block 16 will limit or guide the moving direction of the fixed block 12 to ensure that it moves along a predetermined trajectory.

[0035] See also Figure 6 In this embodiment, the outer end of the movable rod 15 passes through the fixed block 12 and is fixedly connected to the handle 3, and the movement of the handle 3 drives the movable rod 15 to move inside the movable groove 13. The outer end of the movable rod 15 passes through the fixed block 12 and is fixedly connected to the handle 3. This connection method ensures that when the handle 3 is subjected to an external force (such as being pulled by the user), the movable rod 15 can move accordingly. When the user holds the handle 3 and pulls it outward, since the handle 3 is fixedly connected to the movable rod 15, the movable rod 15 will move inside the movable groove 13 accordingly.

[0036] See also Figure 6 In this embodiment, two limit blocks 16 are respectively slidably connected to the adjustment slots 14 on both sides of the movable slot 13. This sliding connection allows the limit blocks 16 to move in a certain direction in the adjustment slot 14, thereby changing its position in the movable slot 13. By adjusting the position of the limit blocks 16 and the adjustment slot 14, the connection state of the movable rod 15 and the fixed block 12 can be adjusted. The adjustment slot 14 provides a moving path and a positioning point for the limit blocks 16. By adjusting the position of the limit blocks 16 in the adjustment slot 14, the moving range and trajectory of the movable rod 15 in the movable slot 13 can be indirectly controlled.

[0037] Example 2 See also Figure 1-6 , this embodiment provides an industrial control network monitoring device that is easy to maintain, including: The mounting plate 1 is fixed in the monitoring position, so that the power line of the monitoring alarm 4 passes through the cable trough 5 and is connected to the corresponding equipment, and the industrial network is monitored through the monitoring alarm 4. During this process, the handle 3 is in a horizontal state, and the limit blocks 16 on both sides of the movable rod 15 are respectively located inside the two adjustment grooves 14. When the handle 3 is accidentally touched due to external collision, the handle 3 drives the movable rod 15 to slide outward inside the movable groove 13 without affecting the position of the fixed block 12 and the positioning block 6. When the monitoring alarm 4 needs to be repaired and replaced, any one of the handles 3 is turned to a vertical state. At this time, the limit block 16 is separated from the adjustment groove 14, and the handle 3 is pulled outward. Under the action of the limit block 16, the fixed block 12 drives the positioning block 6 to separate from the card-jointing groove on the outside of the monitoring alarm 4, and the movement of the positioning block 6 drives the corresponding two adjusting rods 7 to move. Under the action of the tooth block 10 and the gear ring 11, the other set of positioning blocks 6 and the adjusting rods 7 move synchronously in the opposite direction, and then the second positioning block 6 is synchronously separated from the outside of the monitoring alarm 4. The monitoring alarm 4 can be removed for maintenance and inspection, and then the new monitoring alarm 4 is put back into the installation slot 2, and the handle 3 is pushed inward to drive the positioning block 6 to reset and engage with the monitoring alarm 4, and cooperate with the pressure generated by the positioning spring 9 to complete the installation of the monitoring alarm 4.
