Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a remote terminal device. Background Technology

[0002] Traffic signal controllers are a type of remote terminal device. With economic development and improved living standards, the number of motor vehicles has increased dramatically, leading to a surge in traffic flow and increasingly severe traffic congestion. This places higher demands on traffic signal control, requiring traffic signal controllers to adjust traffic flow more precisely and flexibly, and optimize intersection efficiency. Traffic management departments can remotely control traffic lights at intersections through traffic signal controllers, such as adjusting signal timing schemes and forcibly switching signal light states, to cope with special situations, such as traffic congestion and emergencies.

[0003] Modern traffic signal controllers typically have communication capabilities, enabling them to communicate with the traffic management center's server via wired or wireless networks. This allows them to transmit collected data to the traffic management center and receive control commands and parameter adjustment information from the center, thus achieving remote monitoring and management.

[0004] Road traffic signal controllers are installed in dedicated cabinets near intersections. Typically, a dedicated signal controller cabinet is set up near the intersection at the pedestrian crossing. However, most existing road traffic signal controllers are installed using screws for fixing. This method of installation is inconvenient due to the confined space, and the limited space also prevents the use of certain installation tools, thus failing to achieve the maximum fixing effect. Furthermore, the frequent traffic of large vehicles at some intersections can cause the screws to loosen due to vibrations. Utility Model Content

[0005] Given that most of the existing road traffic signal controllers are installed using screws for fixing, this method is inconvenient to install in confined spaces. The limited space also makes it impossible to operate some installation tools, thus preventing the fixing effect from reaching its maximum.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Reference Figure 1-3 This first embodiment of the present invention discloses a remote terminal device, comprising: a rectangular protective cabinet body 1 and electronic components 2. The rectangular protective cabinet body 1 is provided with electronic components 2. The rectangular protective cabinet body 1 is also provided with a rectangular loading plate 3. A traffic signal 4 is also provided on the upper surface of the rectangular loading plate 3. The rectangular protective cabinet body 1 is also provided with a fixing structure 5. The fixing structure 5 includes: a rectangular mounting sleeve 6 and a rectangular fixing plate 7. The rectangular mounting sleeve 6 is provided on the upper surface of the rectangular loading plate 3. The rectangular fixing plate 7 is fixedly installed on the vertical surface of the rectangular mounting sleeve 6. Mounting blocks 8 of the same size are installed on the vertical surface of the rectangular fixing plate 7.

[0031] A pair of mounting blocks 8 are connected to the same cylindrical guide rod 9. A rectangular moving block 10 is slidably connected to the rod body of the cylindrical guide rod 9. A rectangular plate is also provided on the vertical surface of the rectangular moving block 10. A rectangular block 11 is also provided on the upper surface of the rectangular plate. Several teeth with the same spacing are provided on the lower surface of the rectangular block 11. An arc-shaped storage sleeve 12 is slidably connected to the end of the rectangular block 11 away from the rectangular moving block 10. A rectangular fixing plate 7 is temporarily fixedly connected to the end of the arc-shaped storage sleeve 12 away from the end of the rectangular block 11.

[0032] A rotating disk is installed through the vertical surface of the rectangular mounting sleeve 6, and a gear disk 13 is installed through the rod of the rotating disk. The teeth of the gear disk 13 are meshed with the teeth of the rectangular block 11. A pair of rectangular moving blocks 10 are fixedly connected to a pair of symmetrical L-shaped connecting plates 14. Fixing plates 15 are installed on the vertical surface of the pair of L-shaped connecting plates 14 away from the cylindrical guide rod 9. Anti-slip layers are provided on the opposite vertical surfaces of the pair of fixing plates 15. A controller 16 is also installed on the vertical surface inside the rectangular protective cabinet body 1. A hydraulic extension rod 17 is also installed on the vertical surface of the rectangular mounting sleeve 6 away from the rectangular fixing plate 7. A connecting block 18 is also installed through the rod of the hydraulic extension rod 17.

[0033] In use, first pick up the traffic signal 4 and place it in the placement slot on the upper surface of the rectangular loading plate 3. Then, directly start the controller 16, as the controller 16 is connected to a control line, and the other end of the control line is connected to the hydraulic extension rod 17. The hydraulic extension rod 17 has a through-connecting block 18, which is connected to the rectangular plate on the vertical surface of the rectangular moving block 10. A moving slot is provided at the intersection of the connecting block 18 and the rectangular mounting sleeve 6. As the hydraulic extension rod 17 retracts, one of the rectangular moving blocks 10 will move. Because the gear disk 13 and the teeth on the pair of rectangular blocks 11 are meshed, the L-shaped connecting plate 14 moves relative to each other, and finally the traffic signal 4 is clamped by a pair of fixing plates 15.

[0034] Example 2:

[0035] Reference Figure 1 and 4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a controller 16 is also provided on the vertical surface inside the rectangular protective cabinet body 1, and a hydraulic extension rod 17 is also installed on the vertical surface of the rectangular mounting sleeve 6 away from the rectangular fixing plate 7. A connecting block 18 that is penetrated is also provided on the rod body of the hydraulic extension rod 17.

[0036] The lower surface of the traffic signal controller 4 is also provided with a pair of arc-shaped sleeves 19. Each pair of arc-shaped sleeves 19 is provided with a pair of rectangular mating plates 20. One of the rectangular mating plates 20 is rotatably connected to a cylindrical fixing rod 21 on its vertical surface. The other rectangular mating plate 20 has a cylindrical hole 22 through its vertical surface, and a threaded groove is provided on the inner ring of the cylindrical hole 22.

[0037] When using it, first follow the operating steps in Example 1 to clamp the traffic signal 4, then pick up the connecting wire that needs to be connected to the traffic signal 4. After the connection is completed, push the arc-shaped clamp 19 with the cylindrical fixing rod 21. After the push is completed, because the vertical surface of another rectangular docking plate 20 has a cylindrical hole 22 through it, and the inner ring of the cylindrical hole 22 has a threaded groove, the threaded groove and the thread on the cylindrical fixing rod 21 are mutually engaged. After the rotation is completed, check whether it is temporarily fixed.

[0038] The remaining structure is the same as that in Example 1.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
