[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0031] The embodiment of the utility model provides a PLC control module, which solves the technical problem that the control unit of the PLC control module in the prior art is inconvenient to disassemble, thereby facilitating the repair or replacement of a damaged control unit.

[0032] like Figure 1 As shown, the PLC control module provided in this embodiment includes a mounting frame 10, a PLC control unit 20 and a locking unit 30. The PLC control unit 20 is movably connected to the mounting frame 10; the locking unit 30 is installed on the PLC control unit 20, and the locking unit 30 has a switchable expanded state and a folded state. The locking unit 30 is used to connect the mounting frame 10 and limit the movement of the PLC control unit 20 relative to the mounting frame 10 in the folded state, and to disconnect from the mounting frame 10 in the expanded state.

[0033] Specifically, the PLC control module is provided with a mounting frame 10, a PLC control unit 20 and a locking unit 30. The PLC control unit 20 can be movably connected to the mounting frame 10, and the locking unit 30 is installed on the PLC control unit 20. The locking unit 30 can be switched between an expanded state and a folded state. When the locking unit 30 is switched to the folded state, it can be connected to the mounting frame 10 and limit the movement of the PLC control unit 20 relative to the mounting frame 10, and the PLC control unit 20 is locked to the mounting frame 10. When the PLC control unit 20 needs to be disassembled, it only needs to switch the locking unit 30 to the expanded state to disconnect it from the mounting frame 10, and the PLC control unit 20 can be disassembled from the mounting frame 10, thereby reducing the difficulty of disassembling the PLC control unit 20 and providing convenience for the disassembly of the PLC control unit 20.

[0034] In this embodiment, Figure 1 As shown, the mounting frame 10 is a plate, and a symmetrical fixing frame 11 is fixed to the rear side of the mounting frame 10 . Each fixing frame 11 is provided with a symmetrical threaded hole, and the fixing frame 11 can be fixed to the control cabinet by screws.

[0035] In this embodiment, Figure 1 As shown, a plurality of PLC control units 20 and locking units 30 are provided, wherein the number and type of PLC control units 20 can be adaptively set according to the actual control requirements of the PLC control module, and each PLC control unit 20 is arranged side by side on the mounting frame 10. When one of the PLC control units 20 is damaged, only the corresponding locking unit 30 needs to be switched to the expanded state, and the damaged PLC control unit 20 can be disassembled separately.

[0036] In this embodiment, Figure 1-2 As shown, each PLC control unit 20 is provided with a heat dissipation window 21 and a wiring port 22 , and the heat dissipation window 21 is used to fan the PLC control unit 20 .

[0037] It is understandable that the locking unit 30 can be directly placed on the surface of the mounting frame 10 and supported by the mounting frame 10, or can be movably arranged in a groove or cavity formed on the mounting frame 10 to achieve a movable connection with the mounting frame 10.

[0038] In one embodiment, Figure 1-3 As shown, the mounting frame 10 is provided with a supply slide 12, the PLC control unit 20 is slidably connected to the supply slide 12, and can slide out of the supply slide 12 along the supply slide 12, and the locking unit 30 can be connected to the supply slide 12 and limit the sliding of the PLC control unit 20 relative to the supply slide 12 when in the retracted state. Specifically, when the locking unit 30 is in the retracted state, it will act as a locking component to limit the sliding of the PLC control unit 20 relative to the supply slide 12, thereby realizing the locking of the PLC control unit 20. Through the sliding connection between the PLC control unit 20 and the supply slide 12, when the locking unit 30 is switched to the unfolded state, the PLC control unit 20 can slide relative to the supply slide 12, and slide out of the supply slide 12 to realize the disassembly of the PLC control unit 20, thereby facilitating the disassembly of the PLC control unit 20 and stabilizing the connection between the PLC control unit 20 and the mounting frame 10.

[0039] It can be understood that the sliding connection between the PLC control unit 20 and the sliding bracket 12 can be achieved by providing a sliding rod that passes through the PLC control unit 20, or providing a sliding groove for the PLC control unit 20 to slide.

[0040] In one embodiment, Figure 2 As shown, the supply slide 12 is provided with a supply slide cavity 121, and a slide plate 23 is fixed to the side of the PLC control unit 20. The slide plate 23 is slidably connected to the supply slide cavity 121, and can slide out of the supply slide cavity 121 along the supply slide cavity 121. Specifically, the PLC control unit 20 can achieve a sliding connection with the supply slide 12 through the cooperation of the slide plate 23 and the supply slide cavity 121, and at the same time, the supply slide cavity 121 can limit the slide plate 23, thereby improving the stability of the PLC control unit 20 and the mounting frame 10.

[0041] In this embodiment, Figure 2 As shown, an opening is provided at the upper end of the slide cavity 121 , and the slide plate 23 can slide out of the slide cavity 121 through the opening of the slide cavity 121 .

[0042] In one embodiment, to facilitate the disassembly of the PLC control unit 20, as shown in FIG. Figure 1-2As shown, a handle 24 is provided on the top of the PLC control unit 20. Specifically, when the locking unit 30 is switched to the unfolded state and is disconnected from the supply slide frame 12, the PLC control unit 20 can be slid out of the upper end opening of the supply slide cavity 121 through the slide plate 23 by simply pulling up the handle 24.

[0043] It can be understood that the locking unit 30 can limit the PLC control unit 20 by clamping the clamping force acting on the mounting frame 10 in the folded state or by being snap-connected with the mounting frame 10. The clamping end of the locking unit 30 can be connected by a spring, a screw or other connecting piece to achieve the folding or unfolding of the clamping end.

[0044] In one embodiment, Figure 2 As shown, the mounting bracket 10 is provided with a locking hole 13 , and the PLC control unit 20 can be connected to the locking hole 13 in the folded state, thereby achieving locking with the mounting bracket 10 .

[0045] It can be understood that the two clamping ends of the locking unit 30 can be connected to the PLC control unit 20 by sliding connection, hinge connection or other connection forms. The clamping ends of the locking unit 30 are moved closer to or unfolded by rotating or sliding, thereby switching the locking unit 30 between the unfolded state and the folded state.

[0046] In one embodiment, Figure 1-3 As shown, the locking unit 30 includes a control module 31 and two locking modules 32 arranged opposite to each other. The control module 31 is connected to the PLC control unit 20 and can be lifted and lowered relative to the PLC control unit 20. The two locking modules 32 are respectively located on both sides of the control module 31. One end of the two locking modules 32 is connected to the control module 31, and the other end of the two locking modules 32 can be connected to or separated from the mounting frame 10 by lifting and lowering the control module 31. Specifically, through the above settings, the locking and unlocking of the PLC control unit 20 can be achieved by lifting and lowering the control module 31, thereby facilitating the disassembly and installation of the PLC control unit 20.

[0047] In this embodiment, when disassembling the PLC control unit 20, it is only necessary to control the control module 31 to descend, so that the two locking modules 32 can be unfolded, forming an unfolded state of the locking unit 30, and realizing the unlocking of the PLC control unit 20. At the same time, the control module 31 can rise to retract the two locking modules 32, forming a locking unit 30 to realize the locking of the PLC control unit 20.

[0048] It can be understood that the control module 31 can be a screw threadedly connected to the PLC control unit 20. The control module 31 can be raised and lowered by rotating the screw. The two locking modules 32 can be opened or closed by being connected to the screw.

[0049] It can be understood that the locking module 32 can be hinged or slidably connected to the PLC control unit 20.

[0050] In one embodiment, Figure 1-3 As shown, the control module 31 includes an elastic member 311 and a connecting seat 312. One end of the elastic member 311 abuts against the PLC control unit 20, and the connecting seat 312 is fixed to the other end of the elastic member 311. One end of the two locking modules 32 close to the control module 31 is connected to the connecting seat 312. Specifically, the elastic member 311 generates an elastic effect on the connecting seat 312, so that the locking module 32 connected to the elastic seat is retracted to achieve the locking of the PLC control unit 20. When the PLC control unit 20 needs to be disassembled, it is only necessary to overcome the elastic force of the elastic member 311 and press the elastic member 311 to expand the locking module 32, so that the PLC control unit 20 can be unlocked, thereby facilitating the disassembly of the PLC control unit 20.

[0051] It can be understood that the elastic member 311 can be any elastic structure with elasticity such as a rubber member, a sponge, etc.

[0052] In one embodiment, Figure 1-3 As shown, the elastic member 311 is a spring.

[0053] In one embodiment, Figure 1-3 As shown, the locking module 32 includes a connecting rod 321 and a locking member 322. The locking member 322 is slidably connected to the PLC control unit 20 and can be connected to the mounting frame 10 by sliding along the PLC control unit 20. One end of the connecting rod 321 is hinged to the control module 31, and the other end of the connecting rod 321 is connected to the hinge. Specifically, by controlling the control module 31 to descend, the connecting rod 321 can be driven to rotate. During the rotation of the connecting rod 321, the locking member 322 will be driven to slide. The locking member 322 can be connected to the mounting frame 10 or disconnected from the mounting frame 10 by sliding, thereby locking or unlocking the PLC control unit 20.

[0054] In one embodiment, Figure 1-3 As shown, the PLC control unit 20 is provided with a limit frame 25, and the lock member 322 passes through the limit frame 25 and is slidably connected to the limit frame 25. Specifically, the limit frame 25 can provide a limit for the sliding of the lock member 322.

[0055] In this embodiment, the lock 322 can be connected to the lock hole 13 by sliding along the PLC control unit 20. Specifically, the lock 322 can lock the PLC control unit 20 by connecting to the lock hole 13, and at the same time, the PLC control unit 20 can be unlocked by disconnecting from the lock hole 13.

[0056] It can be understood that the shape and size of the locking element 322 can be adaptively set according to the position of the locking hole 13 .

[0057] In this embodiment, Figure 1-3 As shown, the locking hole 13 is arranged on the outer side of the supply slide 12, and the locking member 322 is a folding member. One side of the locking member 322 is in contact with the top surface of the supply slide 12 and is hinged to the connecting rod 321 through the limit frame. The other side of the locking member 322 is located on the side of the supply slide 12 and extends downward. The locking hole 13 can be connected by sliding the locking member 322 toward the slide 12.

[0058] The specific working principle of the PLC control module provided by the utility model is as follows: the elastic member 311 can generate a force acting on the lock member 322 in the direction of the lock hole 13 by generating an upward elastic force acting on the connecting seat 312, so that the lock member 322 is connected to the lock hole 13, and the PLC control unit 20 is locked. When the PLC control unit 20 is disassembled, it is only necessary to overcome the elastic force of the elastic member 311 to press the connecting seat 312, so that the connecting seat 312 drives the connecting rod 321 to rotate, so that the lock member 322 is moved away from the lock hole 13. The PLC control unit 20 can be unlocked by sliding in the right direction to disengage the lock member 322 from the lock hole 13. After the PLC control unit 20 is unlocked, the PLC control unit 20 is pulled up by the handle 24 to slide along the slide cavity 121 through the slide plate 23 and slide out of the slide cavity 121, thereby removing the PLC control unit 20 for maintenance or replacement. The PLC control unit 20 can be disassembled without any disassembly tools, thereby facilitating the disassembly of the PLC control unit 20.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
