Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to a PLC controller stabilization structure. Background Art

[0002] PLC controllers are core components in industrial automation, designed specifically to control and manage various mechanical equipment and production processes. They receive signals from input devices such as sensors and switches, rapidly process them according to pre-set logic, and precisely control the actions of output devices such as motors, valves, and lights. The PLC's powerful functionality stems from the efficient computational power of its central processing unit, the flexible configuration of its input / output modules, and the stability of its power supply and communication modules.

[0003] Announcement No. CN221010507U discloses a card-mounted PLC controller. The installation block, connecting slide rod, spherical slider and return spring are provided to facilitate sliding of the installation block. At the same time, the return spring can support the spherical slider and pull the installation block into the interior of the square slide groove, thereby facilitating the connection and disassembly of the PLC controller body.

[0004] However, in the above solution, the mounting block and the square groove clamp the controller mounting rod to fix the position of the PLC controller body, but the fitting surface between the mounting block and the controller mounting rod is relatively smooth. When subjected to external force vibration, the controller will slide horizontally on the controller mounting rod, causing the connection between the controller and the input and output devices to loosen, resulting in signal interruption.

[0005] Therefore, we propose a PLC controller stability structure to solve the above problems. Utility Model Content

[0006] (1) Technical problems solved

[0007] In view of the deficiencies of the prior art in the above background technology, the purpose of the present invention is to provide a PLC controller stabilization structure to solve the problems raised in the above background technology.

[0008] (2) Technical solution

[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A PLC controller stabilizing structure comprises a guide rail and a card holder arranged at the rear side of the controller body, wherein a fixing mechanism is arranged between the card holder and the guide rail;

[0011] The guide rail includes a U-shaped rail plate and extension plates arranged on both sides of the rail plate and extending outwards;

[0012] The card seat includes a seat plate and end plates fixed to the upper and lower ends of the seat plate and extending away from the controller body;

[0013] The fixing mechanism includes a baffle slidably mounted on one side of the end plate, the baffle forming a slot with the base plate and the end plate that is engaged with the extension plate, a connecting block is provided on one side of the baffle, an adjusting rod is rotatably mounted inside the base plate, both ends of the adjusting rod are provided with threaded sections that are threadedly connected to the connecting block, a plurality of protrusions are equidistantly arranged on the extension plate along its extension direction, and a groove that is adapted to the protrusion is provided at the bottom of the baffle.

[0014] Furthermore, the end plate is provided with a guide groove which is slidably connected to the connecting block.

[0015] Furthermore, the thread directions of the two thread segments are opposite.

[0016] Furthermore, an extension rod is provided at the top of the threaded section above the seat plate, and a knob is fixed at the top of the extension rod.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] By setting a fixing mechanism between the guide rail and the card seat, after rotating the adjusting rod in the fixing mechanism, the threaded section drives the baffle to move downward through the connecting block, and cooperates with the seat plate and the end plate to form a slot that is connected to the extension plate to prevent the card seat from falling off the rail. The protrusion of the baffle cooperates with the groove on the extension plate to prevent the card seat from sliding on the guide rail, thereby preventing the connection between the controller and the input and output devices from loosening, resulting in signal interruption.

[0025] 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.

[0026] See also Figure 1-4 As shown, the utility model provides a PLC controller stabilization structure, comprising a guide rail 1 and a holder 2 arranged on the rear side of a controller body 4, with a fixing mechanism 3 provided between the holder 2 and the guide rail 1; the guide rail 1 comprises a U-shaped rail plate 11 and extension plates 12 arranged on both sides of the rail plate 11 and extending outward; the holder 2 comprises a base plate 21 and end plates 22 fixed to the upper and lower ends of the base plate 21 and extending away from the controller body 4;

[0027] The fixing mechanism 3 includes a baffle 31 slidably mounted on one side of the end plate 22. The baffle 31, the seat plate 21 and the end plate 22 form a slot that is engaged with the extension plate 12. A connecting block 32 is provided on one side of the baffle 31. The end plate 22 is provided with a guide groove 5 that is slidably connected to the connecting block 32. An adjusting rod 33 is rotatably mounted inside the seat plate 21. Both ends of the adjusting rod 33 are provided with threaded sections 34 that are threadedly connected to the connecting block 32. The threads on the two threaded sections 34 are in opposite directions. A plurality of protrusions 35 are equidistantly arranged on the extension plate 12 along its extension direction. A groove 36 that is adapted to the protrusion 35 is provided at the bottom of the baffle 31.

[0028] When installing, the adjusting rod 33 is rotated forward. Since the threads on the two threaded sections 34 are in opposite directions, the adjusting rod 33 drives the connecting block 32 and the baffle 31 to move away from each other, and then the ends of the two extension plates 12 on the guide rail are respectively fitted into the two end plates 22. Then the adjusting rod 33 is flipped over, driving the connecting block 32 and the baffle 31 to move toward each other, forming a slot that engages with the extension plate 12 with the base plate 21 and the end plate 22, limiting the card seat 2 to prevent it from falling from the guide rail 1; when the baffle 31 clamps the extension plate 12, the protrusion 35 on the outside of the extension plate 12 is clamped into the groove 36 on the inside of the baffle 31, limiting the card seat 2 to prevent it from sliding on the guide rail 1
