Description

Technical Field

[0001] This utility model relates to the field of controller installation technology, and in particular to a modular layered plug-in controller installation structure. Background Technology

[0002] In the early days of industrial automation control cabinet installation, the common method was to directly bolt the controller housing to the mounting backplate or crossbeam of the cabinet using multiple bolts. This method required installers to manually align, insert, and tighten the bolts one by one within the confined space of the cabinet, a cumbersome and time-consuming process. Especially when installing or removing multiple controllers, the extensive bolt tightening work resulted in low efficiency and caused inconvenience for routine maintenance, replacement, or system expansion.

[0003] ② To address the efficiency issues of bolt-fixing methods, a rail-based installation method has been widely adopted. The core of this approach is to first fix a standard-section slide rail to the mounting backplate, with a matching slot designed on the back of the controller. During installation, simply align the top of the slot on the back of the controller with the top of the slide rail, and then slide it downwards to suspend and initially position the controller on the rail. This method eliminates the need to tighten each bolt individually, enabling rapid mounting of the controller and significantly improving installation and disassembly efficiency.

[0004] ③ However, while this rail-mounted installation method improves efficiency, it also introduces new limitations. Its main drawback lies in the simplification of the installation method, making it unsuitable for diverse on-site installation conditions. When the control cabinet has a unique spatial layout, or when subsequent modifications result in the lack of suitable vertical walls or columns for mounting the rails, this rail-dependent installation method becomes impossible. Furthermore, for controllers that rely solely on sliding slots for mounting, the displacement constraint along the rail direction may be insufficient under vibration, posing a risk of loosening. This means that existing solutions lack a comprehensive approach that balances the convenience of rapid installation, stability under vibration, and flexibility in handling different installation scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a modular layered plug-in controller installation structure, which solves the technical problems of existing guide rail installation methods, such as the single installation form, inability to adapt to diverse installation scenarios, and poor stability due to insufficient displacement constraint in vibration environments.

[0006] To achieve the above objectives, this utility model provides a modular layered plug-in controller installation structure, including a controller body formed by multiple plug-in modules connected in series. A first sliding groove is provided on the rear side of the controller body, and the first sliding groove is slidably disposed on the outside of a slide rail. Storage grooves are respectively provided on the upper and lower sides of the sliding groove on the rear side of the controller body. Rotating plates are respectively installed in the storage grooves through pins, and assembly holes are respectively provided on the rotating plates.

[0007] The slide rail is also provided with two limiting blocks, which are respectively attached to both sides of the controller body.

[0008] The limiting block is provided with a second sliding groove on its rear side, and the second sliding groove is slidably disposed on the outside of the slide rail.

[0009] The limiting block has a locking screw hole in the middle of its front side, and the locking screw hole is connected to the second sliding groove.

[0010] The locking screws are threadedly installed in the locking screw holes, and the ends of the locking screws abut against the slide rails.

[0011] A fixing plate is fixedly installed on the rear side of the slide rail, and a number of fixing holes are spaced apart on the two sides of the fixing plate adjacent to the slide rail.

[0012] This utility model discloses a modular, layered plug-in controller installation structure. The main body of the structure is a controller body formed by multiple plug-in modules connected in series. Its core installation feature is a first sliding groove on the rear side of the controller body, allowing it to be easily slidably attached to a pre-fixed slide rail, achieving basic and rapid installation. To overcome the limitation of a single installation method, storage slots are cleverly designed on the upper and lower sides of the first sliding groove on the rear side of the controller body. Each storage slot contains a rotating plate hinged by a pin, and the rotating plate has assembly holes. This design allows the rotating plate to be flipped out of the storage slot and directly fixed using the assembly holes when slide rail installation is not possible, thus greatly enhancing the adaptability of the installation method to different site environments.

[0013] To further enhance installation stability, especially in preventing the controller body from shifting along the slide rail under vibration conditions, this structure introduces a limiting block mechanism. The limiting block is slidably mounted on the slide rail through its own structure and can be moved to a position close to both sides of the controller body. It is then fixed by a locking mechanism, thereby achieving effective clamping and limiting of the controller body. In summary, this installation structure, through the cooperation of the first sliding groove and the slide rail, the retractable rotating plate, and the adjustable limiting block, not only inherits the convenience of sliding installation but also integrates the flexibility of direct installation and enhances installation reliability, effectively solving the problems of limited installation methods and insufficient stability in existing technologies.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4 .

[0022] The present invention provides a modular layered plug-in controller installation structure, including a controller body 102 composed of multiple plug-in modules 101 connected in series. A first sliding groove 103 is machined on the rear shell of the controller body 102. The core function of the first sliding groove 103 is to enable it to be directly slidably installed on the outside of a slide rail 104 with a specific cross-sectional shape, thereby realizing the initial suspension and positioning of the controller body 102 on the slide rail 104.

[0023] To ensure the stability of the controller body 102 on the slide rail 104 and prevent it from sliding along the slide rail 104, two limiting blocks 108 are also installed on the slide rail 104. Each of these two limiting blocks 108 has a second sliding groove 109 on its rear side, allowing it to be slidably installed on the outside of the slide rail 104. During installation, the two limiting blocks 108 are moved along the slide rail 104 to a position that tightly fits against the left and right sides of the controller body 102, thus achieving approximately lateral movement of the controller body 102. To further lock the position of the limiting block 108, a locking screw hole 110 is provided in the middle of the front side of each limiting block 108. The locking screw hole 110 communicates with the interior of the second sliding groove 109. By screwing the locking screw 111 into the locking screw hole 110 and making its end tightly abut against the surface of the slide rail 104, the limiting block 108 can be firmly fixed to the desired position on the slide rail 104 by friction, thereby reliably clamping the controller body 102 onto the slide rail 104.

[0024] The foundation of the entire installation structure lies in the fixing of the slide rail 104; a fixing plate 112 is welded or fixed to the rear side of the slide rail 104 by screws. The function of the fixing plate 112 is to provide an installation base for the entire slide rail 104 system; on the fixing plate 112, on both sides adjacent to the length direction of the slide rail 104, a number of fixing holes 113 are spaced apart. These fixing holes 113 are used to insert screws or rivets to firmly install the entire installation structure on the back plate of the distribution cabinet or other installation base.

[0025] Furthermore, to address installation scenarios where the slide rail 104 cannot be used, this structure provides an alternative direct installation solution. Storage slots 105 are machined on the rear side of the controller body 102, on the upper and lower sides of the first sliding groove 103. Each storage slot 105 contains a rotating plate 106 hinged to it via a pin. In the default state, the rotating plate 106 can be rotated and retracted into the storage slot 105, maintaining the flatness of the controller body 102's side. When direct installation is required, the rotating plate 106 can be flipped out of the storage slot 105. Using the assembly holes 107 on the rotating plate 106, screws or other fasteners can be used to directly fix the controller body 102 to the mounting surface, greatly enhancing installation flexibility and environmental adaptability.

[0026] Working principle: The slide rail 104 is securely installed onto the target base, such as the mounting plate inside the power distribution cabinet, through the fixing holes 113 on the fixing plate 112 on its rear side; after the slide rail 104 is fixed, the controller body 102 slides from top to bottom or horizontally to the outside of the slide rail 104 through the first sliding groove 103 opened on its rear side, realizing the initial suspension or positioning of the controller body 102; subsequently, the two limiting blocks 108 slide onto the slide rail 104 through their own second sliding grooves 109, and move along the slide rail 104 to positions that are tightly fitted to the left and right sides of the controller body 102, thereby constraining the degree of freedom of the controller body 102 on the slide rail 104 and preventing it from sliding accidentally along the slide rail 104.

[0027] To ensure the absolute fixation of the position of the limit block 108, the locking screw 111, which is inserted into the locking screw hole 110 on the front side of the limit block 108, is rotated so that the end of the locking screw 111 directly abuts against the surface of the slide rail 104. The locking force generated by the thread is used to firmly lock the limit block 108 in the current position. This action completes the final clamping and fixing of the controller body 102, forming a stable mechanical structure composed of the slide rail 104, the controller body 102, and the limit blocks 108 on both sides, ensuring the reliable installation of the controller in a vibration environment.

[0028] Furthermore, this installation structure provides flexible alternative installation methods to adapt to different installation conditions. When the slide rail 104 cannot be used for installation, the rotating plate 106, which is mounted by a pin in the storage slot 105 located on the upper and lower sides of the first sliding groove 103 on the rear side of the controller body 102, can be rotated around the pin and flipped out of the storage slot 105. The assembly hole 107 on the flipped-out rotating plate 106 can then be used to directly fix the controller body 102 to the mounting surface using screws or other fasteners, achieving direct wall-mounted installation without the need for the slide rail 104. This design allows the same controller body 102 to be quickly and conveniently installed by the slide rail 104, and can also be converted to the traditional direct fixing method when space is limited or specific needs are required, greatly improving installation adaptability and flexibility. The entire working principle clearly demonstrates how the components work together, achieving convenient installation, stability, and adaptability to multiple scenarios.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
