Description

Technical Field

[0001] This application relates to the field of programmable logic controller (PLC) devices, and more particularly to an adapter connection structure that allows for easy assembly and disassembly of modules. Background Technology

[0002] Currently, most control system products use mechanical screws or screws with clips for fastening. Installation requires specialized tools, resulting in low installation efficiency and a large operating space. This leads to a decrease in the overall volume ratio of the system within the control cabinet, and therefore needs improvement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides an adapter connection structure that allows for easy assembly and disassembly of modules, aiming to solve the aforementioned problems.

[0004] An adapter connection structure with easy modular assembly and disassembly includes a module and a base. The base has an installation slot for the module to snap into. A fixing component is installed in the installation slot. The fixing component includes a fixing seat and a flexible fixing arm. The fixing arm and the fixing seat are both connected to the bottom wall of the installation slot. A locking block is rotatably connected to the fixing seat. A locking lever is connected to the locking block. The module has a locking port for the locking lever to snap into. The fixing arm has a positioning slot. A locking block is connected to the inner side wall of the positioning slot. The module has a clearance slot for the fixing arm to snap into. A flexible positioning block is connected to the inner side wall of the clearance slot. The positioning block engages with the locking block.

[0005] By adopting the above technical solution and using a snap-fit ​​design, the module and the base can be connected without the use of screws or tools, which significantly improves the installation efficiency. The locking block and locking lever work together with the locking port for main positioning, and the combination of the snap-fit ​​block and the positioning block further enhances the connection stability. This reduces the operating space required for traditional screw connections, which is conducive to a compact layout inside the control cabinet and improves the volume ratio.

[0006] Optionally, a limiting block for inserting into the module is connected to the bottom wall of the mounting slot.

[0007] By adopting the above technical solution, the limiting block is inserted into the module, guiding the module to accurately enter the installation slot and preventing misalignment. The limiting block plays an auxiliary support role, improving the vibration resistance and offset resistance after connection. Users do not need to manually align precisely, reducing the difficulty of operation.

[0008] Optionally, a fastening block is connected to the side wall of the module, and the locking block has a fastening groove for the fastening block to be engaged.

[0009] By adopting the above technical solution, after the module is pressed into place, the fastening block is locked into the fastening groove, thereby adding an additional mechanical locking structure on the basis of the original locking and enhancing the reliability of the overall connection.

[0010] Optionally, the locking block is provided with a driving ramp, and a plurality of anti-slip strips are connected in parallel on the driving ramp.

[0011] By adopting the above technical solution, the driving slope can provide guidance when pressed, so that the locking block can be smoothly rotated and released. The anti-slip strip increases the friction between the finger and the driving surface, preventing slippage that could cause misoperation or injury, improving the user experience, facilitating operation by hand, and avoiding the use of tools.

[0012] Optionally, the upper edge of the card block is chamfered.

[0013] By adopting the above technical solution, the chamfer reduces the resistance when the block enters the relief groove, thus improving the smoothness of assembly.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. The snap-on design allows for connection between the module and the base without the need for screws or tools, significantly improving installation efficiency. The locking block and locking lever work together with the locking port for main positioning, while the combination of the snap-on block and the positioning block further enhances the connection stability. This reduces the operating space required for traditional screw connections, which is conducive to a compact layout inside the control cabinet and increases the volume ratio.

[0016] 2. After the module is pressed into place, the fastening block is inserted into the fastening groove, thereby adding an additional mechanical locking structure on the basis of the original locking, enhancing the reliability of the overall connection.

[0017] 3. The drive ramp provides guidance when pressed, allowing the locking block to rotate and release smoothly. The anti-slip strip increases the friction between the finger and the drive surface, preventing slippage that could cause misoperation or injury, improving the user experience, facilitating operation by hand and eliminating the need for tools.

[0027] This application discloses an adapter connection structure that facilitates modular assembly and disassembly. (Refer to...) Figure 1 It includes module 1 and base 2, and the base 2 has a mounting slot 21 for module 1 to be inserted.

[0028] Reference Figure 2 , Figure 3 and Figure 4The mounting slot 21 contains several fasteners, including a fixing base 3 and a fixing arm 4, both made of PC material. The fixing arm 4 and the fixing base 3 are fixedly connected to the bottom wall of the mounting slot 21. A locking block 31 is rotatably connected to the fixing base 3, and a locking lever 32 is fixedly connected to the locking block 31. A locking slot 11 is provided on the module 1 for the locking lever 32 to engage. A positioning slot 41 is provided on the fixing arm 4, and a locking block 42 is connected to the inner wall of the positioning slot 41. A clearance slot 12 is provided on the module 1 for the fixing arm 4 to engage, and a positioning block 121 is integrally formed on the inner wall of the clearance slot 12, engaging with the locking block 42. The snap-fit ​​design allows for the connection between module 1 and base 2 without the need for screws or tools, significantly improving installation efficiency. The locking block 31 and locking lever 32, along with the locking port 11, are used for main positioning. At the same time, the locking block 42 and positioning block 121 work together to further enhance connection stability, reducing the operating space required for traditional screw connections. This is conducive to a compact layout inside the control cabinet and increases the volume ratio.

[0029] Reference Figure 1 A limiting block 22 for inserting the module 1 is fixedly connected to the bottom wall of the mounting slot 21. The limiting block 22 is inserted into the module 1, guiding the module 1 to accurately enter the mounting slot 21 and preventing misalignment.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The upper edge of the locking block 42 is provided with a chamfer 421. The chamfer 421 reduces the resistance when the locking block 42 enters the relief groove 12, and improves the smoothness of assembly.

[0033] The implementation principle of the adapter connection structure for easy assembly and disassembly of the module in this application embodiment is as follows: Through the snap-on design, the connection between the module 1 and the base 2 can be completed without the use of screws or tools, which significantly improves the installation efficiency. The locking block 31 and the locking lever 32 are used in conjunction with the locking port 11 for main positioning. At the same time, the connection stability is further enhanced by the cooperation of the locking block 42 and the positioning block 121. The operation space required for traditional screw connection is reduced, which is conducive to the compact layout inside the control cabinet and improves the volume ratio.
