Description

Technical Field

[0001] The utility model belongs to the technical field of modular PLC controllers, and in particular relates to a modular PLC controller installation structure with hidden slots. Background Art

[0002] A modular PLC controller is a programmable controller (PLC) with a modular structure, which is composed of different modules to achieve different control functions. This PLC controller adopts a universal module design, so that each module is independent, and the components are fixed on a standard rail through a bus for combination. This modular PLC controller has many advantages. First, due to its modular structure, users can choose different modules to combine according to actual needs to meet different control requirements. Secondly, since each module is independent, it can be easily expanded or modified without affecting other modules. In addition, due to its universal module design, PLC controllers of different brands can be easily interchanged, thereby reducing maintenance costs. The existing modular PLC controller has the following problems during use:

[0003] When using a modular PLC controller, the modular PLC controller needs to be docked and assembled with a mounting plate. Since the mounting plate is provided with a slot that matches the modular PLC controller, when the mounting plate is empty and not docked with the modular PLC controller, the slot on the mounting plate will be exposed, causing foreign dust and impurities to adhere to the inside of the slot, affecting the docking with the modular PLC controller. Utility Model Content

Since the mounting plate is provided with a slot that matches the modular PLC controller, when the mounting plate is empty and not docked with the modular PLC controller, the slot on the mounting plate will be exposed, resulting in external dust and impurities adhering to the inside of the slot, which affects the docking with the modular PLC controller.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, the utility model provides a modular PLC controller installation structure with a hidden slot, the installation structure comprising a mounting plate and a PLC control module, the PLC control module is mounted on the surface of the mounting plate, a docking plate is mounted at the recess of the mounting plate, and a slot is opened on the surface of the docking plate;

[0008] A sliding protection mechanism is arranged inside the docking plate, and a mounting mechanism is arranged on the side of the PLC control module.

[0009] When using the installation structure of the present technical solution, the PLC control module is docked with the docking plate on the surface of the mounting plate. When there is space, the adjustment block is pushed to cover and hide the slot with the protective plate to avoid dust accumulation inside the slot when not in use. Then, the assembly plates on both sides of the PLC control module are slidably docked with the fixing seat to facilitate quick and stable docking of the PLC control module, reduce the inconvenience of symmetrical disassembly of the threads, and improve assembly efficiency.

[0010] Preferably, the sliding protection mechanism comprises a protection plate, an adjustment block, an iron sheet and a weak magnet, and the protection plate is made of PVC.

[0012] Furthermore, an iron sheet is connected to the surface of one end of the protection plate close to the adjustment block, and a weak magnet is connected to the inner wall of the opening of the docking plate. The weak magnet is magnetically attracted to the iron sheet. By magnetically attracting the weak magnet to the iron sheet, the protection plate can be easily placed stably.

[0013] Furthermore, the mounting mechanism includes an assembly plate, a fixing seat, a sliding plate, a movable rod, a linkage plate, a linkage spring and a locking buckle, and the bottom ends of both sides of the PLC control module are connected with the assembly plate. By using the mounting mechanism, the complexity of the screw installation process can be reduced, thereby facilitating disassembly and assembly.

[0014] Furthermore, a fixing seat is installed on the surface of the mounting plate, and a sliding plate is connected to the bottom opening of the fixing seat, and the sliding plate and the sliding groove on the surface of the assembly plate form a sliding connection structure. By sliding the sliding plate along the sliding groove on the surface of the assembly plate, the assembly plate can be stably docked.

[0015] Furthermore, a movable rod is movably connected to the opening at one end of the fixing seat, a linkage plate is connected to the bottom end of the movable rod, a linkage spring is connected to the surface of the linkage plate, a locking buckle is connected to the other side of the linkage plate, and the locking buckle and the opening on the surface of the assembly plate form a chimeric structure. By docking the locking buckle with the opening on the surface of the assembly plate, the PLC control module can be installed firmly.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model connects the PLC control module with the docking plate on the surface of the mounting plate. When there is space, the adjustment block is pushed. Through the cooperation between the protection plate, the adjustment block, the iron sheet and the weak magnet, the protection plate covers and hides the slot, thereby avoiding the accumulation of dust inside the slot when not in use.

[0019] 2. The utility model facilitates the rapid and stable docking of the PLC control module by slidingly docking the assembly plates on both sides of the PLC control module with the fixed base, and then cooperates with the sliding plate, the movable rod, the linkage plate, the linkage spring and the locking buckle, thereby reducing the inconvenience of symmetrical disassembly of the thread and improving the assembly efficiency.

[0031] A sliding protection mechanism is arranged inside the docking plate 3 , and a mounting mechanism is arranged on the side of the PLC control module 2 .

[0032] Among them, the sliding protection mechanism includes a protection plate 5, an adjustment block 6, an iron sheet 7 and a weak magnet 8. The protection plate 5 is made of PVC. The surface of the protection plate 5 is connected to the adjustment block 6. The top surface of the adjustment block 6 is flush with the top surface of the docking plate 3. The surface of one end of the protection plate 5 close to the adjustment block 6 is connected to the iron sheet 7. The inner wall of the opening of the docking plate 3 is connected to the weak magnet 8, and the weak magnet 8 is magnetically attracted to the iron sheet 7.

[0033] In addition, the installation mechanism includes an assembly plate 9, a fixed seat 10, a sliding plate 11, a movable rod 12, a linkage plate 13, a linkage spring 14 and a locking buckle 15.

[0034] Working principle: When using the device of the present technical solution, the PLC control module 2 is docked with the docking plate 3 on the surface of the mounting plate 1. When there is space, the adjustment block 6 is pushed to drive the protection plate 5 to slide at the inner wall opening of the docking plate 3, and at the same time drive the protection plate 5 to gradually cover the surface of the slot 4. In addition, if the slot 4 is used, the adjustment block 6 is pushed in the opposite direction, so that the iron sheet 7 at one end of the protection plate 5 is attracted to the weak magnet 8, the slot 4 is opened, and the protection plate 5 covers and hides the slot 4 to avoid dust accumulation inside the slot 4 when not in use; further through The assembly plates 9 on both sides of the PLC control module 2 are slidably docked with the fixed seats 10, so that the sliding plates 11 on the bottom of the fixed seats 10 slide along the openings on the surface of the assembly plates 9.
