[0001] The utility model relates to the technical field of controllers, in particular to a multi-channel transmission controller. Background Art

[0002] A multi-channel transmission controller is a device with multiple channels that can simultaneously control or process multiple signal transmissions. It can be used in various different fields and application scenarios. In the field of wireless communication, it is applicable to ultra-low power wireless communication for gateways, smart speakers, and other smart home devices. The multi-channel transmission controller can collect data from various common external sensors, analyze and process the data, and give an alarm in a timely manner for abnormal data. With the continuous progress of society, in order to ensure that people can use various resources in a healthy and safe manner, it is necessary to monitor various resource supply devices in real time, such as power supply systems, industrial control systems, and networks.

[0003] When the existing multi-channel transmission controller works, it generally drives air flow through a built-in fan, so that the controller dissipates heat through the ventilation openings provided on the surface, thereby ensuring the normal operation of internal components. When it is necessary to maintain the internal components, it is necessary to remove the cover plate by turning bolts. This operation not only takes a long time, but also the connected cover plate is still prone to gaps, resulting in dust entering, reducing the practicability. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-7 , the present invention provides a technical solution: a multi-channel emission controller, including a controller housing 1, a circuit board body 2, a first installation groove 3, a second installation groove 4, a first cover plate 5, a second cover plate 6, a linkage slider 7, an auxiliary piston column 8, a first magnet 9, a second magnet 10, a positioning block 11, a limit slide plate 12, an air guide groove 13, a support baffle 14 and a sealing airbag 15. The side surface of the controller housing 1 is provided with heat dissipation holes, and a cavity is arranged inside the controller housing 1. The side surfaces at both ends of the first installation groove 3 are both inclined designs. The width of the upper opening of the first installation groove 3 is greater than the width of its lower opening. The width of the lower opening of the first installation groove 3 is the same as the opening width of the second installation groove 4. The side surfaces at both ends of the first cover plate 5 are both inclined designs. The width of the upper surface of the first cover plate 5 is greater than the width of its lower surface. The width of the lower surface of the first cover plate 5 is the same as the width of the second cover plate 6. When using this device, first slide the two limit slide plates 12 to facilitate unlocking the first cover plate 5 for disassembly. After removing the first cover plate 5 and the second cover plate 6, it is convenient to disassemble and maintain the circuit board body 2.

[0032] The bottom surface of the cavity of the controller housing 1 is fixedly installed with a circuit board body 2. A first installation groove 3 is opened on the upper surface of the controller housing 1. A second installation groove 4 is opened at the lower end of the first installation groove 3. The inner walls of the first installation groove 3 and the second installation groove 4 are provided with a first cover plate 5. One end of the linkage slider 7 is in an arc design. A spring is connected between the auxiliary piston column 8 and the inner wall of the opening of the first installation groove 3. When installing the first cover plate 5 and the second cover plate 6, the first cover plate 5 and the second cover plate 6 are inserted into the first installation groove 3 and the second installation groove 4. The inclination surfaces of the first cover plate 5 and the first installation groove 3 are used for limiting. At the same time, by pressing down the first cover plate 5, its inclined surface pushes the linkage slider 7 to slide, and the linkage slider 7 drives the first magnet 9 to move through the auxiliary piston column 8.

[0033] A second cover plate 6 is fixedly connected to the lower end of the first cover plate 5. There are two openings provided on the inner wall of the first installation groove 3, and a linkage slider 7 is slidably connected in the opening of the first installation groove 3. One end of the linkage slider 7 is fixedly connected to an auxiliary piston column 8. A first magnet 9 is fixed on the upper surface of one end of the auxiliary piston column 8. The opposite ends of the first magnet 9 and the second magnet 10 have opposite magnetic poles. The upper end of the positioning block 11 penetrates through the upper surface of the controller housing 1, and a spring is connected between the positioning block 11 and the inner wall of the opening of the first installation groove 3. A spring is connected between the limit slide plate 12 and the controller housing 1, and a groove is provided on the lower surface of the limit slide plate 12. The first magnet 9 slides horizontally close to and attracts the second magnet 10, so that the second magnet 10 drives the positioning block 11 to slide down to unlock the limit slide plate 12. The limit slide plate 12 is pushed by the spring on its surface to move, so that the limit slide plate 12 limits the first cover plate 5 to prevent the first cover plate 5 from loosening.

[0034] A positioning block 11 is slidably connected to the top surface of the opening of the first installation groove 3, and a second magnet 10 is fixed to the lower end of the positioning block 11. Two limit slide plates 12 are slidably connected to the upper surface of the controller housing 1. A support baffle 14 is fixedly connected to the inner wall of the second installation groove 4. An air guide groove 13 is provided between the controller housing 1 and the support baffle 14. A sealing airbag 15 is fixed to the upper surface of the support baffle 14. The air guide groove 13 is respectively communicated with the auxiliary piston column 8 and the sealing airbag 15. The support baffle 14 is of an annular design, and the sealing airbag 15 is of an annular design. While the auxiliary piston column 8 slides, the auxiliary piston column 8 pushes air into the air guide groove 13, and the air guide groove 13 then fills the air into the sealing airbag 15, so that the annular sealing airbag 15 expands, facilitating the sealing airbag 15 to fit and seal the lower surface of the second cover plate 6, thereby preventing external dust from entering.

[0035] Working principle: When using this multi-channel emission controller, by sliding the two limit slide plates 12, the first cover plate 5 and the second cover plate 6 are unlocked, which is convenient for maintaining the circuit board body 2. By pressing down the first cover plate 5 and the second cover plate 6, the linkage slider 7 and the auxiliary piston column 8 are pushed to slide, so that the first magnet 9 attracts the second magnet 10 to drive the positioning block 11 to release the limit slide plate 12, which is convenient for the spring to push the limit slide plate 12 to limit the first cover plate 5. The auxiliary piston column 8 fills the air into the sealing airbag 15 through the air guide groove 13, so that the sealing airbag 15 expands and fits the second cover plate 6, thereby preventing dust from entering and increasing the overall practicability.
