Description

Serial port expansion module supporting multi-protocol conversion Technical Field The utility model relates to the technical field of computer communication, in particular to a serial port expansion module supporting multi-protocol conversion. Background The serial port expansion module supporting multi-protocol conversion is a hardware component for expanding the serial port number of equipment and realizing conversion of different communication protocols, and is generally provided with a plurality of serial communication interfaces which can be connected with a plurality of equipment conforming to different communication protocols and convert data formats, electric characteristics or communication rules among different protocols so as to realize interconnection and intercommunication among heterogeneous equipment, the serial port expansion module is widely applied to equipment such as a connecting PLC, a sensor, an executor and the like and realizes cooperative work among different equipment, however, the traditional serial port expansion module has a plurality of defects in terms of a cover dismounting structure, the complicated disassembly mode of the device often requires specialized tools and complicated operation steps, such as disassembling a plurality of screws, opening a tightly attached shell by using a prying tool, and the like, which not only leads to that when equipment is maintained, maintenance personnel consume a great deal of time and energy to disassemble the cover and contact the components which are required to be maintained inside, but also can cause physical damage to the internal circuits and the components, such as line breakage, welding spot falling, interface deformation, and the like, in the operation process, thereby causing equipment failure, and causing the problems of production line stagnation, data acquisition interruption, network communication paralysis, and the like. In view of the above and related technologies, the inventor considers that there is often a defect that when an expansion module body needs maintenance, due to the complex disassembly structure, the traditional disassembly structure causes maintenance delay, so that a production line in an industrial automation scene is stopped, data acquisition is interrupted, or network communication is paralyzed in an internet of things system due to module failure, and therefore, a serial port expansion module supporting multi-protocol conversion is provided for the problem. Disclosure of utility model The utility model aims to solve the defects that when an expansion module body needs to be maintained, a traditional disassembly structure is complex, so that overhaul is delayed, a production line in an industrial automation scene is stopped, data acquisition is interrupted, or network communication is paralyzed in an Internet of things system due to module faults, and provides a serial port expansion module supporting multi-protocol conversion. In order to achieve the purpose, the serial port expansion module supporting multi-protocol conversion comprises an expansion module body and a machine cover, wherein the surface of the expansion module body is in sliding connection with the machine cover, a power supply interface is arranged on the surface of the machine cover, a plurality of communication interfaces are arranged on the surface of the machine cover, dismounting devices are arranged on two sides of the machine cover, each dismounting device comprises two fixing plates, the two fixing plates are fixedly connected with two sides of the machine cover respectively, fixing frames are fixedly connected to two sides of the expansion module body, the inner wall of each fixing frame is in sliding connection with the corresponding fixing plate, a groove is formed in the inner wall of each fixing frame, a first spring is fixedly connected to the inner wall of each groove, one end of each first spring is fixedly connected with a limiting block, a limiting groove is formed in the surface of each fixing plate, a through hole is formed in the surface of each fixing frame, a threaded rod penetrates through the inner wall of each threaded rod, and one end of each threaded rod is fixedly connected with a rotating plate. The effects achieved by the components are as follows: through setting up dismounting device, reached the effect to carrying out quick assembly disassembly to the cover on the extension module body, make things convenient for its maintenance, when the extension module body needs to maintain, the maintenance personal only need unscrew the threaded rod, press the stopper and break away from the spacing groove, can easily lift off the cover, the internal element of quick contact, compare in traditional complicated dismantlement structure, the device has shortened maintenance time by a wide margin, avoided leading to maintenance delay because of traditional dismantlement structure is complicated in industrial automation
