[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-3 , the utility model provides a technical solution:
[0019] A field distributed remote IO module includes an IO module body 1, a mounting notch 2 is provided in the middle position of the bottom end surface of the IO module body 1, and limiting guide grooves 5 are respectively provided on both sides of the mounting notch 2. A DIN guide rail body 3 is provided on the inner side of the mounting notch 2, which passes through the mounting notch 2 from front to back. A movable splint 4 is provided on the inner side of the DIN guide rail body 3, which is in contact with the vertical end of the DIN guide rail body 3. A central support block 6 is fixedly connected to the upper position of the inner side of the limiting guide groove 5, and a forward and reverse screw rod 15 is provided across the middle position of the central support block 6. A first slider 7 is externally threaded on one side of the forward and reverse screw rod 15, and a second slider 8 is externally threaded on the other side of the forward and reverse screw rod 15. The bottom of the second slider 8 is fixedly connected to a movable buckle body 9, and a shaft 10 is fixedly connected to the side of the forward and reverse screw rod 15 away from the middle position of the IO module body 1.
[0020] like Figure 1 As shown, a socket 13 is provided at the top front end of the IO module body 1, and there are two sockets 13 in total. A display light 14 is provided adjacent to one side of the socket 13. The display light 14 is fixedly installed at the top front end of the IO module body 1. After the IO module body 1 establishes a reliable wired connection with the external power supply, the display light 14 will light up to serve as a prompt.
[0021] like Figure 1 and Figure 2 As shown, the IO module body 1 and the limiting guide groove 5 are integrally formed, and the IO module body 1 and the shaft rod 10 are rotatably connected. The radius of the shaft rod 10 is smaller than the radius of the forward and reverse screw rods 15. The setting of the shaft rod 10 mainly serves to assist in extending the forward and reverse screw rods 15; notches 11 are respectively provided on the end faces of both sides of the IO module body 1, and an anti-slip handle 12 fixedly connected to one side end of the shaft rod 10 is provided on the inner side of the notch 11. The anti-slip handle 12 and the shaft rod 10 are coaxially arranged. Under the pre-embedded limitation of the notch 11, the screw rod limiting structure can be quickly adjusted by rotating the anti-slip handle 12.
[0022] like Figure 1 、 Figure 2 and Figure 3As shown, the forward and reverse screw rods 15 are rotatably connected by limiting the guide groove 5 and the IO module body 1, and the movable splint 4 and the first slider 7 are fixedly connected. The threaded axes on both sides of the surface of the forward and reverse screw rods 15 are set in opposite directions, and the outer shape of the movable buckle body 9 is set in an "L"-shaped structure. The height of the movable splint 4 is greater than the height of the movable buckle body 9. When the forward and reverse screw rods 15 are rotated, the movable buckle body 9 and the movable splint 4 will realize the same direction and reverse stretching operations toward the position of the center support block 6. In this way, a set of screw rod limiting structures can clamp and withdraw the DIN guide rail body 3.
[0023] Working process: The power required for the startup and operation of the device in the present invention all comes from an external power supply, and when the entire IO module body 1 is in use, an external output power supply can be connected by wire through one of the sockets 13. When the on-site distributed remote IO module is needed, first, after the DIN rail body 3 is pre-fastened and installed, the IO module body 1 can be clipped onto the DIN rail body 3 through the docking of the installation notch 2 and the DIN rail body 3. Then, under the connection of the notch 11, the upper and lower sets of shafts 10 are rotated respectively through the anti-slip handle 12. At this time, the shaft 10 realizes a rotary rotation with the forward and reverse screw rods 15, so that the first slider 7 carries the movable splint 4 and the second slider 8 carries the movable buckle body 9 to realize the same direction movement and stretching toward the position of the center support block 6, while moving to the center after being in place. The support block 6 will press against the inner side of the vertical end of the DIN rail body 3, and the movable snap body 9 will squeeze and limit the vertical end angle position of the DIN rail body 3, so that the IO module body 1 can be stably installed on the DIN rail body 3. When the IO module body 1 needs to be disassembled and maintained later, under the limiting effect of the notch 11, the anti-slip handle 12 is rotated in the opposite direction according to the above operation. While the shaft 10 rotates with the forward and reverse screws 15, the movable splint 4 will remove the pressure on the DIN rail body 3 and gradually retract to the middle position of the installation notch 2. The movable snap body 9 will remove the pressure on the DIN rail body 3 and gradually move away from the installation notch 2 and retract into the inside of the limiting guide groove 5, so that the operator can quickly remove the entire IO module body 1 without using tools.
[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
