Description

Technical Field

[0001] This utility model relates to the field of electrical communication technology, specifically to an easy-to-maintain Internet of Things (IoT) roadside monitoring terminal. Background Technology

[0002] With the deep integration of IoT technology and intelligent transportation systems, roadside monitoring terminals, as the core equipment of traffic sensing networks, are widely used in various traffic scenarios such as urban roads, highways, and national and provincial trunk roads. They mainly collect key data such as traffic flow, vehicle driving status, road environmental parameters, and traffic violations through various sensors, and realize real-time data uploading and interaction with the help of IoT communication modules. This provides accurate and comprehensive data source support for traffic control and scheduling, road operation and maintenance, and smart travel services, and is an important foundation for realizing intelligent and digital traffic management.

[0003] These types of terminals typically need to be deployed on mounting posts, brackets, or other carriers along roadsides, operating continuously and uninterruptedly in complex outdoor environments such as high temperatures, rain, snow, dust, and vibration. This places high demands on the structural stability, environmental adaptability, and anti-interference capabilities of the equipment. Furthermore, to ensure the continuous and reliable operation of roadside monitoring terminals, regular on-site maintenance, fault diagnosis, and sensor and component replacement have become standard practice in the industry. The unique characteristics of outdoor operations, however, create a practical need for convenient maintenance of the monitoring terminals.

[0004] However, existing IoT roadside monitoring terminals have the following drawbacks during operation: the terminals and mounting brackets mostly use fixed connection structures such as bolts and clips, and unlocking and resetting the fixed limit requires professional tools, which is cumbersome and time-consuming, greatly reducing the efficiency of outdoor maintenance. After the terminal is disassembled upwards, there is no stable temporary support structure, and maintenance requires continuous manual support, which is difficult for a single person to complete and consumes a lot of manpower. After the terminal is fixed, the orientation cannot be adjusted, making it difficult for maintenance personnel to adjust the terminal to a view that is easy to observe the internal components when working outdoors, which increases the difficulty of maintenance operations. Utility Model Content

[0005] The present invention aims to provide an easy-to-maintain IoT roadside monitoring terminal, mainly to solve the problems of cumbersome disassembly and assembly operations, lack of stable temporary support structure requiring manual lifting, and inability to adjust the orientation of the terminal during the maintenance of existing IoT roadside monitoring terminals.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An easy-to-maintain IoT roadside monitoring terminal includes a mounting base on which the terminal body is placed. Two support frames are fixedly connected to the top of the mounting base, with the terminal body positioned between the two support frames. A sliding ring is slidably mounted on each support frame, and a connecting ring is rotatably connected inside the sliding ring. Two limiting grooves are formed through the connecting ring. Two movable rods slide through the outer wall of the terminal body, and two limiting blocks are fixedly connected to the outer wall of each movable rod, with the two limiting blocks slidably penetrating the outer wall of the terminal body. A second tension spring is provided on the inner wall of the terminal body for the movement of the movable rods, and the movable rods can... The sliding passage is through the connecting ring. The outer walls of adjacent limiting blocks are respectively adapted to the adjacent limiting grooves. A placement cylinder is fixedly connected to the top of the support frame. A rotating plate is rotatably connected inside the placement cylinder. An embedding hole adapted to one end of the moving rod is opened on one side of the rotating plate. Two limiting grooves connected to the embedding holes are opened on one side of the rotating plate. The outer walls of adjacent limiting blocks are respectively adapted to the adjacent embedding holes. Several positioning holes are opened on the outer wall of the rotating plate. A positioning rod adapted to several positioning holes slides through the outer wall of the placement cylinder. A first tension spring for moving the positioning rod is provided on the outer wall of the placement cylinder.

[0008] The working principle and beneficial effects of this utility model:

[0009] 1. Working Principle: In the initial state, the terminal body is placed on the mounting base, and the second tension spring is in a naturally compressed state. Its elastic force pushes the moving rod to extend outward from the terminal body, allowing the moving rod to slide through the connecting ring. At the same time, the limiting block on the outer wall of the moving rod passes through the limiting groove on the connecting ring, realizing the engagement and limiting of the terminal body with the connecting ring and the sliding ring, thus restricting the terminal body between the two support frames. When maintenance of the terminal body is required, pull the terminal body upward, causing the sliding ring to slide vertically upward along the support frame. When the moving rod approaches the placement cylinder at the top of the support frame, press the moving rod inward into the terminal body. At this time, the second tension spring is stretched, causing the moving rod and the limiting block to engage and limit the connection between the terminal body and the connecting ring and the sliding ring. The block is retracted into the terminal body and released from the constraint of the connecting ring; the terminal body continues to move upward, so that the end of the moving rod is aligned with the embedding hole of the rotating plate inside the placement cylinder. The moving rod is released, the second tension spring returns to its original position and releases its elastic force, pushing the moving rod into the embedding hole. At the same time, the limiting block is locked into the limiting groove communicating with the embedding hole, realizing the temporary support of the terminal body at the placement cylinder; then the terminal body can be rotated, driving the rotating plate to rotate synchronously inside the placement cylinder. After adjusting to an angle that is convenient for maintenance personnel to operate, the elastic force of the first tension spring pulls the positioning rod into the positioning hole at the corresponding position of the rotating plate, realizing the angle positioning of the rotating plate, thereby fixing the maintenance viewing angle of the terminal body.

[0010] 2. Beneficial Effects: In the initial state, due to the force of the second tension spring, the moving rod and the limiting block pass through the connecting ring and the limiting groove respectively, thereby restricting the terminal body between the two support frames. Furthermore, pulling the terminal body upwards, when the moving rod approaches the placement cylinder, pushes the moving rod inwards, causing it to be housed inside the connecting rod. At this time, the second tension spring is compressed, continuously moving the terminal body upwards. When the moving rod moves to align with the embedding hole on one side of the rotating plate, it works with the second tension spring to move the moving rod and the limiting block into the embedding hole and the limiting groove respectively, thus supporting the position of the terminal body. Subsequently, the first tension spring facilitates the insertion of the positioning rod into positioning holes at different angles, thereby adjusting the rotation angle of the terminal body so that it faces the maintenance personnel, facilitating inspection of the internal condition of the terminal body and subsequent maintenance work.

[0011] Preferably, the support frame has sliding grooves on both sides, and sliders are slidably connected inside the two sliding grooves. One end of each slider is fixedly connected to the outer wall of the sliding ring. The sliding grooves provide vertical guidance and lateral limitation for the sliders, so that the sliding ring drives the connecting ring to slide smoothly up and down along the support frame, avoiding deviation and shaking.

[0012] Preferably, a fixed plate is fixedly connected to one end of the moving rod, and the second tension spring is sleeved on the outside of the moving rod and the outside of the adjacent limiting block. One end of the second tension spring is fixedly connected to one side of the fixed plate, and the other end is fixedly connected to the inner wall of the terminal body. The fixed plate provides stable force support for the second tension spring, and the tension spring sleeve structure restricts its extension and contraction direction to ensure that the elastic force is transmitted along the axial direction of the moving rod.

[0013] Preferably, one end of the moving rod and the adjacent limiting block both extend to the outside of the connecting ring; in the initial state, the limiting block is fully engaged with the limiting groove; during maintenance, it is convenient for the moving rod, the limiting block and the embedding hole and limiting groove of the rotating plate to be quickly aligned and engaged.

[0014] Preferably, a plurality of the positioning holes are arranged in a circular array at equal intervals along the periphery of the rotating plate, and a manhole is provided on one side of both the placement cylinder and the rotating plate; the circular array of equally spaced positioning holes enables precise multi-angle positioning of the rotating plate (terminal body) and adapts to different maintenance perspectives; the manhole facilitates maintenance personnel to move the moving rods inside the rotating plate.

[0015] Preferably, a baffle is fixedly connected to the top of the positioning rod, and the first tension spring is sleeved on the outside of the positioning rod. One end of the first tension spring is fixedly connected to the bottom of the baffle, and the other end is fixedly connected to the outer wall of the placement cylinder. The baffle provides force support for the first tension spring and limits the movement of the positioning rod to prevent it from sliding into the placement cylinder. The tension spring sleeve prevents extension and displacement, so that the positioning rod can be accurately inserted into or disengaged from the positioning hole to realize the positioning and unlocking of the rotating plate.

[0016] Preferably, the outer diameter of the sliding ring and the outer diameter of the connecting ring are the same as the width of the inner wall of the support frame; this ensures that the sliding ring and the connecting ring fit tightly against the inner wall of the support frame, eliminates lateral gaps, prevents them from shifting or swaying during sliding and rotation, and improves the stability of the structure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7An easy-to-maintain IoT roadside monitoring terminal includes a mounting base 1, on which a terminal body 2 is placed. Two support frames 3 are fixedly connected to the top of the mounting base 1, with the terminal body 2 located between the two support frames 3. A sliding ring 6 is slidably disposed on the support frame 3. Sliding grooves 4 are formed on both sides of the support frame 3, and sliders 5 are slidably connected inside each of the two sliding grooves 4. One end of each slider 5 is fixedly connected to the outer wall of the sliding ring 6. A connecting ring 7 is rotatably connected inside the sliding ring 6. The outer diameters of the sliding ring 6 and the connecting ring 7 are the same as the width of the inner wall of the support frame 3. Two limiting grooves 8 are formed through the connecting ring 7.

[0027] Two movable rods 19 slide through the outer wall of the terminal body 2. Two limiting blocks 16 are fixedly connected to the outer wall of the movable rods 19, and the two limiting blocks 16 can slide through the outer wall of the terminal body 2. A second tension spring 18 for moving the movable rods 19 is provided on the inner wall of the terminal body 2. A fixing plate 17 is fixedly connected to one end of the movable rods 19. The second tension spring 18 is sleeved on the outer side of the movable rods 19 and the outer side of the adjacent limiting blocks 16. One end of the second tension spring 18 is fixedly connected to one side of the fixing plate 17, and the other end is fixedly connected to the inner wall of the terminal body 2. The movable rods 19 can slide through the connecting ring 7. The outer walls of the adjacent limiting blocks 16 are respectively adapted to the adjacent limiting grooves 8. One end of the movable rods 19 and the adjacent limiting blocks 16 both extend to the outer side of the connecting ring 7.

[0028] In the initial state, the mounting base 1 is fixed to the external position to be fixed by bolts, and the terminal body 2 is located on the mounting base 1. The second tension spring 18 is naturally compressed, and its elastic force pushes the moving rod 19 to extend outward of the terminal body 2 through the fixing plate 17. The moving rod 19 slides through the connecting ring 7, and at the same time the limiting block 16 passes through the limiting groove 8 of the connecting ring 7 and extends to the outside, realizing the engagement and limiting of the terminal body 2 and the connecting ring 7. The sliding ring 6 cooperates with the sliding groove 4 of the support frame 3 through the slider 5, so that the terminal body 2 is limited between the two support frames 3. At this time, the terminal body 2 can normally collect and transmit traffic data.

[0029] A placement cylinder 9 is fixedly connected to the top of the support frame 3. A rotating plate 10 is rotatably connected inside the placement cylinder 9. Both the placement cylinder 9 and the rotating plate 10 have manholes on one side. An embedding hole 11 adapted to one end of the moving rod 19 is opened on one side of the rotating plate 10. Two limiting grooves 20 connected to the embedding holes 11 are opened on one side of the rotating plate 10. The outer walls of adjacent limiting blocks 16 are adapted to adjacent embedding holes 11. When the terminal body 2 needs to be maintained and repaired, the maintenance personnel pull the terminal body 2 directly upward. The terminal body 2 drives the connecting ring 7 and the sliding ring 6 to move upward synchronously. The slider 5 slides vertically upward along the sliding groove 4. When the end of the moving rod 19 is close to the placement cylinder 9 at the top of the support frame 3, the maintenance personnel press the moving rod 19 into the terminal body 2. The moving rod 19 drives the second tension spring 18 on one side of the fixed plate 17 to stretch, so that the moving rod 19 and the limiting block 16 move into the connecting ring 7 and the limiting groove 8.

[0030] Continue to pull the terminal body 2 upward so that the end of the moving rod 19 is precisely aligned with the insertion hole 11 of the rotating plate 10 inside the placement cylinder 9. Then release the moving rod 19, the second tension spring 18 resets and releases its elastic force, pushing the moving rod 19 into the insertion hole 11. At the same time, the limiting block 16 is engaged in the limiting groove 20 that communicates with the insertion hole 11, thus achieving temporary support for the terminal body 2 at the placement cylinder 9. No manual lifting is required, providing ample operating space for maintenance personnel.

[0031] The outer wall of the rotating plate 10 is provided with a plurality of positioning holes 12, which are arranged in a circular array at equal intervals along the periphery of the rotating plate 10. The outer wall of the placement cylinder 9 is slidably penetrated by a positioning rod 13 that is adapted to the plurality of positioning holes 12, and the outer wall of the placement cylinder 9 is provided with a first tension spring 15 for moving the positioning rod 13. A baffle 14 is fixedly connected to the top of the positioning rod 13, and the first tension spring 15 is sleeved on the outside of the positioning rod 13. One end of the first tension spring 15 is fixedly connected to the bottom end of the baffle 14, and the other end is fixedly connected to the outer wall of the placement cylinder 9.

[0032] If the orientation of the terminal body 2 needs to be adjusted, the maintenance personnel pull the baffle 14 at the top of the positioning rod 13 upwards. The baffle 14 stretches the first tension spring 15 and drives the positioning rod 13 to move upwards, so that the positioning rod 13 disengages from the positioning hole 12 of the rotating plate 10, thereby releasing the positioning restriction on the rotating plate 10. Then, the terminal body 2 is rotated, and the terminal body 2 drives the moving rod 19 and the limiting block 16 to rotate synchronously, thereby driving the rotating plate 10 to rotate inside the placement cylinder 9. After adjusting to an angle that is convenient for the maintenance personnel to observe and operate, the baffle 14 is released, the first tension spring 15 resets and pulls the positioning rod 13 downwards to slide into the positioning hole 12 at the corresponding position of the rotating plate 10, thereby achieving the angular positioning of the rotating plate 10 and fixing the maintenance viewing angle of the terminal body 2. The maintenance personnel can then begin to inspect, repair, or replace parts of the terminal body 2.

[0033] As can be seen from the above, the specific implementation of this utility model is as follows: In the initial state, the mounting base 1 is fixed to the external position that needs to be fixed by bolts, and the terminal body 2 is located on the mounting base 1. The second tension spring 18 is naturally compressed, and its elastic force pushes the moving rod 19 to extend outward to the outside of the terminal body 2 through the fixing plate 17. The moving rod 19 slides through the connecting ring 7, and at the same time, the limiting block 16 passes through the limiting groove 8 of the connecting ring 7 and extends to the outside, so as to realize the engagement and limiting of the terminal body 2 and the connecting ring 7. The sliding ring 6 cooperates with the sliding groove 4 of the support frame 3 through the slider 5, so that the terminal body 2 is limited between the two support frames 3. At this time, the terminal body 2 can normally collect and transmit traffic data.

[0034] When maintenance and repair of the terminal body 2 are required, the maintenance personnel pull the terminal body 2 directly upward. The terminal body 2 drives the connecting ring 7 and the sliding ring 6 to move upward synchronously, and the slider 5 slides vertically upward along the slide groove 4. When the end of the moving rod 19 approaches the placement cylinder 9 at the top of the support frame 3, the maintenance personnel press the moving rod 19 into the terminal body 2. The moving rod 19 drives the second tension spring 18 on one side of the fixed plate 17 to stretch, so that the moving rod 19 and the limiting block 16 move into the connecting ring 7 and the limiting groove 8.

[0035] Continue to pull the terminal body 2 upward so that the end of the moving rod 19 is precisely aligned with the insertion hole 11 of the rotating plate 10 inside the placement cylinder 9. Then release the moving rod 19, the second tension spring 18 resets and releases its elastic force, pushing the moving rod 19 into the insertion hole 11. At the same time, the limiting block 16 is engaged in the limiting groove 20 that communicates with the insertion hole 11, thus achieving temporary support for the terminal body 2 at the placement cylinder 9. No manual lifting is required, providing ample operating space for maintenance personnel.

[0036] If the orientation of the terminal body 2 needs to be adjusted, the maintenance personnel pull the baffle 14 at the top of the positioning rod 13 upwards. The baffle 14 stretches the first tension spring 15 and drives the positioning rod 13 to move upwards, so that the positioning rod 13 disengages from the positioning hole 12 of the rotating plate 10, thereby releasing the positioning restriction on the rotating plate 10. Then, the terminal body 2 is rotated, and the terminal body 2 drives the moving rod 19 and the limiting block 16 to rotate synchronously, thereby driving the rotating plate 10 to rotate inside the placement cylinder 9. After adjusting to an angle that is convenient for the maintenance personnel to observe and operate, the baffle 14 is released, the first tension spring 15 resets and pulls the positioning rod 13 downwards to slide into the positioning hole 12 at the corresponding position of the rotating plate 10, thereby achieving the angle positioning of the rotating plate 10 and fixing the maintenance viewing angle of the terminal body 2. The maintenance personnel can then begin to inspect, repair or replace parts of the terminal body 2.

[0037] After maintenance and repair work is completed, the maintenance personnel first pull the baffle 14 upward to disengage the positioning rod 13 from the positioning hole 12, and rotate the terminal body 2 back to the initial vertical position. Then, they press the moving rod 19 into the terminal body 2 to disengage the moving rod 19 and the limiting block 16 from the embedding hole 11 and the limiting groove 20. At this time, the moving rod 19 is still inside the connecting ring 7. The maintenance personnel can directly push the terminal body 2 downward to drive the connecting ring 7 and the sliding ring 6 to descend vertically along the sliding groove 4 of the support frame 3. When the moving rod 19 is separated from the placement cylinder 9, the moving rod 19 is released, and the second tension spring 18 resets and pushes the moving rod 19 and the limiting block 16 to pass through the limiting groove 8 of the connecting ring 7 again, realizing the re-engagement and limiting of the terminal body 2 and the connecting ring 7, and completing the entire maintenance and reset operation.

[0038] Alternatively, by pressing the moving rod 19 inside the terminal body 2, the moving rod 19 and the limiting block 16 can be completely disengaged from the connecting ring 7 and the limiting groove 8, thereby making it easy to disassemble the terminal body 2 from the two support frames 3 for subsequent replacement.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
