[0020] The following is combined Figures 1 to 14 The following describes embodiments of the present invention.

[0021] According to an embodiment of the present invention, in one aspect, a device fixing structure 1 is provided, which is fixed on a device mounting base 2, including: a fixing buckle 11, the fixing buckle 11 including a first plate 1101 and a first clamping part 1102 disposed on the first plate 1101; a movable buckle 12, which is slidably connected to the fixing buckle 11, the movable buckle 12 including a second plate 1202, the second plate 1202 being provided with a second clamping part 1201; and a driving assembly connected to the movable buckle 12, which is used to drive the second plate 1202 to slide relative to the first plate 1101, so that different clamping spaces are formed between the first clamping part 1102 and the second clamping part 1201, wherein the first clamping part 1102 and the second clamping part 1201 are used to clamp a guide rail 3 so that the device is fixed to the guide rail 3.

[0022] The second plate 1202 slides relative to the first plate 1101 through a drive component connected to the movable latch 12, thereby creating different clamping spaces for the first clamping part 1102 and the second clamping part 1201 to accommodate guide rails 3 of different sizes. When dealing with guide rails 3 of different sizes, the first clamping part 1102 and the second clamping part 1201 are adjusted to engage and fix with the guide rail 3, offering advantages of wide adaptability and versatility. In this embodiment, the device is an I / O module, and the mounting base 2 is the mounting base 2 for the I / O module.

The first clamping portions 1102 are used to clamp the first side edge 301 of the guide rail 3. The provision of the two first clamping portions 1102 makes the engagement between the first plate 1101 and the guide rail 3 more stable.

[0024] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9As shown, the second plate 1202 includes a second base plate 12021, a third side plate 12022 and a fourth side plate 12023 connected to the second base plate 12021. The third side plate 12022 and the fourth side plate 12023 are respectively provided with a second clamping part 1201. The second clamping part 1201 is used to clamp the second side edge 302 of the guide rail 3. When the driving assembly drives the second plate 1202 to slide relative to the first plate 1101, the second base plate 12021 slides relative to the first base plate 11011, the third side plate 12022 slides relative to the first side plate 11012, and the fourth side plate 12023 slides relative to the second side plate 11013, so that the second plate 1202 slides relative to the first plate 1101, and the first clamping part 1102 and the second clamping part 1201 respectively clamp the two sides of the guide rail 3 from both sides.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 and Figure 9 As shown, both the first clamping part 1102 and the second clamping part 1201 are U-shaped grooves, and the opening direction of the first clamping part 1102 and the opening direction of the second clamping part 1201 are arranged opposite to each other.

The first bending portion 11014 is used to limit the sliding of the third side plate 12022, and the second bending portion 11015 is used to limit the sliding of the fourth side plate 12023. The first bending portion 11014, the first side plate 11012, and the first bottom plate 11011 form a semi-enclosed structure, allowing the third side plate 12022 to slide within the semi-enclosed structure, thereby limiting the sliding of the third side plate 12022; the second bending portion 11015, the second side plate 11013, and the second bottom plate 12021 form a semi-enclosed structure, allowing the fourth side plate 12023 to slide within the semi-enclosed structure, thereby limiting the sliding of the fourth side plate 12023 and ensuring the stability of the sliding. It should be noted that the first side plate 11012 and the second side plate 11013 in this embodiment have the same size specifications, and the end faces of the first clamping part 1102 of the first side plate 11012 and the first clamping part 1102 of the second side plate 11013 are flush and have the same size specifications.

The sliding groove and the slide rail 1205 are adapted to each other, realizing the sliding of the movable buckle 12 relative to the fixed buckle 11.

[0028] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 10 As shown, the driving assembly includes a guide rod 13, and the first plate 1101 also includes a guide plate 1103. The guide plate 1103 has a first guide hole 1104 and is connected to the first base plate 11011. The movable buckle 12 has a limiting plate 1203 and is connected to the second base plate 12021. The limiting plate 1203 has a second guide hole 1204. The first guide hole 1104 and the second guide hole 1204 are arranged along the same central axis. The guide rod 13 passes through the first guide hole 1104 and the second guide hole 1204 in sequence and is then fixedly connected to the movable buckle 12. In this embodiment, the inner diameters of the first guide hole 1104 and the second guide hole 1204 are the same, and the outer diameter of the guide rod 13 is slightly smaller than the inner diameter of the first guide hole 1104 to facilitate the movement of the guide rod 13 relative to the first guide hole 1104.

[0029] In one embodiment, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 12 As shown, it also includes a retaining ring 18. The guide rod 13 includes a guide end 1301, and the outer periphery of the guide end 1301 is provided with two spaced annular slots 1302. Each annular slot 1302 is connected to a retaining ring 18, and the space between the two retaining rings 18 is sufficient to accommodate the limiting plate 1203. In this embodiment, the retaining rings 18 have openings. After the guide end 1301 passes through the second guide hole 1204, the retaining rings 18 are engaged with the annular slots 1302 on both sides of the limiting plate 1203, so that the space between the two retaining rings 18 just accommodates the limiting plate 1203, and the guide rod 13 moves relative to the fixed buckle 11 to drive the movable buckle 12 to move. For ease of guidance, as... Figure 7 , Figure 10 As shown, the end of the guide end 1301 is tapered.

The elastic element 17 is disposed between the guide plate 1103 and the limiting plate 1203, and is sleeved on the outer periphery of the guide rod 13. The guide rod 13 also has a connecting end 1303, which extends out of the movable buckle 12 and is fixedly connected to the pull rod 14. Specifically, the elastic element 17 is a spring, and both the elastic element 17 and the retaining ring 18 are standard parts, easy to purchase and replace. In this embodiment, the spring is in a compressed state when the equipment fixing structure 1 is loose from the guide rail 3, and in a natural state when the equipment fixing structure 1 clamps the guide rail 3. In this embodiment, as Figure 10 , Figure 11 As shown, the pull rod 14 is "L" shaped, the connecting end 1303 is provided with an internal threaded hole 1304, and the pull rod 14 is provided with an external threaded end 1401. The internal threaded hole 1304 and the external threaded end 1401 are adapted to realize the rotational connection between the pull rod 14 and the guide rod 13.

[0031] In one embodiment, such as Figure 3 , Figure 8 As shown, the first base plate 11011 is provided with a mounting hole 1105 and a limiting hole 1106. A fastener 15 passes through the mounting hole 1105 to fix the first base plate 11011, and a positioning pin 16 passes through the limiting hole 1106. The mounting hole 1105 and the limiting hole 1106 are used to fix the equipment fixing structure 1 to the equipment mounting base 2. In this embodiment, there is one mounting hole 1105, and the fastener 15 is used to achieve a fixed connection between the fixing buckle 11 and the mounting base 2; there are two limiting holes 1106, and one positioning pin 16 is provided for each limiting hole 1106. Through the cooperation of the fastener 15 and the positioning pin 16, the movable buckle 12 can move between the mounting hole 1105 and the limiting hole 1106.

[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the mounting base 2 includes a mounting base plate 21. The mounting base plate 21 has fastening holes 26 and positioning holes 27. Mounting holes 1105 and fastening holes 26 are correspondingly arranged, and limiting holes 1106 and positioning holes 27 are correspondingly arranged. The mounting base plate 21 of the mounting base 2 has a first mounting boss 22 and a second mounting boss 24. The first mounting boss 22 has a first through hole 23, and the second mounting boss 24 has a second through hole 25. In this embodiment, as... Figure 4 , Figure 5As shown, the first through hole 23 is gourd-shaped, the second through hole 25 is open, the fastening hole 26 is a threaded hole, the mounting hole 1105 is a through hole, the fastener 15 is a bolt, the bolt passes through the mounting hole 1105 and is rotatably connected to the fastening hole 26 to realize the fixed connection between the fixing buckle 11 and the mounting base plate 21; the positioning hole 27 is a threaded hole, the limiting hole 1106 is a through hole, and the end of the positioning pin 16 is threaded so that the positioning pin 16 passes through the limiting hole 1106 and is threadedly connected to the positioning hole 27.

[0033] In this embodiment, as Figure 3 , Figure 4 , Figure 14 As shown, the first mounting boss 22 and the second mounting boss 24 are protruding from the mounting base plate 21. That is, the first mounting boss 22, the second mounting boss 24, and the mounting base plate 21 form a groove. The fixing structure 1 is disposed in the groove, and the first mounting boss 22 and the second mounting boss 24 are along the length direction ( Figure 4 The second mounting boss 24 (in the Z-axis direction) extends out of the mounting base 2 to meet the user's wall-mounting installation needs. It should be noted that the second through hole 25 of the second mounting boss 24 is "U"-shaped, and the bent end of the "L"-shaped pull rod 14 is located inside the second through hole 25.

[0034] To accommodate mounting bases 2 of different lengths, a series of pull rods 14 of different lengths will be provided to fit mounting bases 2 of different lengths.

[0035] According to an embodiment of the present invention, in a second aspect, an industrial control device is also provided, wherein the industrial control device is an I / O module, and the industrial control device includes a mounting base 2 and a device fixing structure 1 as described above.

[0036] According to an embodiment of the present invention, in a third aspect, an industrial control equipment system is also provided, including one or more of the above-mentioned industrial control equipment and a guide rail 3, wherein each industrial control equipment is mounted on the guide rail 3 through an equipment fixing structure 1.

[0037] In the specific implementation process, after the equipment fixing structure 1 is fixed to the mounting base 2, the on-site personnel pull the pull rod 14 by hand or with the help of tools. The pull rod 14 drives the guide rod 13, and the guide rod 13 drives the movable buckle 12 to move away from the first clamping part 1102. This causes the elastic element 17 to be in a compressed state. The distance between the first clamp and the second clamp is greater than the width of the guide rail 3. The first clamping part 1102 moves along the side wall of the guide rail 3 to the preset position. The pull rod 14 is released, and the compressed elastic element 17 drives the guide rod 13 to move towards the first clamping part 1102. This allows the first clamping part 1102 and the second clamping part 1201 to work together to clamp the two sides of the guide rail 3 respectively, thereby achieving a fixed connection with the guide rail 3. When it is necessary to separate the guide rail 3 from the equipment fixing structure 1, the pull rod 14 is pulled again, causing the movable buckle 12 to move away from the first clamping part 1102, thereby separating the second clamp from the guide rail 3.

[0038] It should be noted that when dealing with mounting bases of different lengths, such as... Figure 2 As shown, it is only necessary to find the corresponding length of the pull rod 14 and connect it to the guide rod 13. Furthermore, as... Figure 13 As shown, when it is not necessary to use the equipment fixing structure 1 to fix the mounting base 2 (when the user only needs to hang it on the wall), the mounting base 2 can be fixed by setting fastening screws in the first through hole 23 and the second through hole 25.

[0039] The device fixing structure 1 provided by this utility model has the following advantages: (1) By connecting the drive component with the movable buckle 12, the second plate 1202 slides relative to the first plate 1101, thereby forming different clamping spaces for the first clamping part 1102 and the second clamping part 1201 to adapt to guide rails 3 of different specifications, which has the advantages of wide adaptability and strong versatility; (2) By setting pull rods 14 of different lengths, it can be compatible with mounting bases 2 of different lengths, thus improving versatility; (3) It can be compatible with both wall-mounted and guide rail 3 working conditions, thus improving the compatibility of the entire device; (4) It has the advantages of high versatility, simple structure and low cost; (5) The pull rod 14 can be pulled without the aid of external tools to separate the device fixing structure 1 from the guide rail 3, thereby improving efficiency and enhancing customer experience.

[0040] As an alternative implementation, the movable buckle 12 is disposed between the mounting hole 1105 and the limiting hole 1106, and the fastener 15 and the positioning pin 16 are also used to slide and limit the movable buckle 12.

[0041] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
