Description

Technical Field

[0001] This utility model relates to the field of PLC control cabinet technology, specifically a PLC control cabinet with expansion function. Background Technology

[0002] A PLC control cabinet, or programmable control cabinet, is a complete control unit that controls motors, switches, and other components. This type of control cabinet features overload, short circuit, and phase loss protection functions, and is compact, stable, and fully functional. It can adapt to various sizes of industrial automation control applications and is widely used in industries such as power, metallurgy, chemical, papermaking, and environmental wastewater treatment. With the development of industrial automation, production lines and processes need continuous upgrading and expansion, thus placing higher demands on the flexibility and scalability of PLC control cabinets.

[0003] According to the patent application CN 221829297U, a PLC control cabinet with expansion function is described as follows: "A PLC control cabinet with expansion function includes a cabinet, wiring frame, junction box, wiring port, branch port, positioning mechanism, fixing plate, mounting plate and adjustment mechanism. Two wiring frames are provided, which are fixedly installed on both sides of the inner wall of the cabinet. Multiple junction boxes are provided, which are slidably installed between the wiring frames. Multiple wiring ports are provided, which are evenly distributed on the side wall of the wiring frame near the junction box."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, the operator simultaneously rotates the handwheels on both sides, causing the limiting post on the mounting plate to align the limiting block with the limiting opening. Then, the operator presses the adjusting ring, causing the limiting block to extend into the limiting cavity and reset under the action of the torsion spring, thus fixing the mounting plate. Pulling the positioning plate simultaneously causes the positioning block to fix the junction box, thus securing it. However, in actual use, adjusting the junction box and mounting plate requires simultaneously pulling the positioning plates on both sides to move the positioning blocks on both sides, or simultaneously pressing the adjusting ring to make the limiting block penetrate into the limiting cavity, to complete the fixing and addition of the junction box and mounting plate. This makes the installation process complex and difficult for workers to disassemble with one hand, increasing the workload and hindering the quick movement, fixing, and addition of the junction box and mounting plate. Therefore, an improved PLC control cabinet with expansion capabilities is needed. Utility Model Content

[0029] Example 1:

[0030] Please see Figure 1-6 This utility model provides a technical solution: a PLC control cabinet with expansion function, including a PLC control cabinet body 1, a cabinet door 2 rotatably connected to the front of the PLC control cabinet body 1, a connecting plate 5 fixedly connected to the inner side of the back of the PLC control cabinet body 1, a slot adjustment frame 6 fixedly connected to the front of the connecting plate 5, an expansion quick-connect synchronization mechanism 3 provided inside the slot adjustment frame 6, and an expansion and capacity increase mechanism 4 provided inside the bottom and top of the PLC control cabinet body 1;

[0031] The expansion quick-connect synchronization mechanism 3 includes an expansion quick-connect component 31 and a synchronization component 32, with the synchronization component 32 disposed inside the expansion quick-connect component 31.

[0032] The expansion quick-connect assembly 31 includes a locking block 311, which is inserted into the locking adjustment frame 6. A connecting post 312 is fixedly connected to the right side of the locking block 311. A limiting frame 314 is fixedly connected to the right side of the connecting post 312.

A junction box 317 is slidably connected to the outside of the push rod 316. A spring 313 is fixedly connected between the locking block and the junction box 317 to facilitate the rapid increase of the number of junction boxes 317 and the adjustment of the position of the junction boxes 317.

[0033] Furthermore, a slot is provided at the corresponding position of the card slot adjustment frame 6 and the card block 311, and the card block 311 is inserted into the slot to facilitate quick fixation of the junction box 317.

[0034] Furthermore, the limiting frame 314 is slidably connected inside the junction box 317, and a slanted groove is provided at the corresponding position of the limiting frame 314 and the limiting post 315, and the limiting post 315 is movably connected in the slanted groove, which facilitates pushing the limiting frame 314 to slide left and right.

[0035] Furthermore, the synchronization component 32 includes a synchronization rod 321, which is fixedly connected to the right side of the adjustment frame. An adjustment column 322 is fixedly connected to the front of the synchronization rod 321. An adjustment frame 323 is movably connected to the outside of the adjustment column 322. An adjustment column 324 is movably connected to the inside of the adjustment frame 323. A connecting block 325 is fixedly connected to the front of the adjustment column 324. A locking block 326 is fixedly connected to the right side of the connecting block 325, which facilitates the simultaneous sliding of the locking block 326 left and right.

[0036] Furthermore, the synchronizing rod 321 is slidably connected inside the junction box 317, and the adjusting frame 323 is rotatably connected inside the junction box 317. The locking adjusting frame 6 and the locking block 326 are provided with slots at corresponding positions, and the locking block 326 is inserted into the slots. The locking block 326 is slidably connected inside the junction box 317, which facilitates the adjustment of the moving position of the locking block 326.

[0037] Example 2:

[0038] Please see Figure 6 Furthermore, in conjunction with Embodiment 1, it is further obtained that the capacity expansion mechanism 4 includes a card frame 41, which is fixedly connected to the bottom and top inner sides of the PLC control cabinet body 1. A fixed inclined block 42 is slidably connected inside the card frame 41, and a spring 43 is fixedly connected between the fixed inclined block 42 and the card frame 41. A fixed frame 44 is inserted inside the card frame 41, and a mounting plate 45 is fixedly connected to the front of the fixed frame 44. A positioning block 46 is fixedly connected to the back of the mounting plate 45. A positioning frame 47 is provided on the bottom and top inner sides of the PLC control cabinet body 1 to facilitate the rapid increase of the number and movement position of the mounting plates 45, thereby expanding the internal capacity.

[0039] Furthermore, the positioning frame 47 and the positioning block 46 are provided with grooves at corresponding positions, and the positioning block 46 is inserted into the groove. The fixing frame 44 and the fixing inclined block 42 are provided with grooves at corresponding positions, and the fixing inclined block 42 is inserted into the groove, so as to facilitate the change of the moving position of the mounting plate 45.

[0040] In actual operation, when the device is used, firstly, through the expansion and extension mechanism 4, when installing the mounting plate 45, simply align the fixing frame 44 on the back of the mounting plate 45 with the corresponding slot of the card frame 41, and simultaneously insert the positioning block 46 into the positioning frame 47, thereby pushing the fixing frame 44 into the corresponding slot of the card frame 41. During the insertion process, the fixing inclined block 42 is pushed downwards. When the fixing frame 44 is fully inserted into the corresponding slot, under the elastic force of the spring 43, the fixing inclined block 42 is inserted into the corresponding slot of the fixing frame 44, thus quickly completing the alignment and fixing of the mounting plate 45. Then, through the expansion quick-connect synchronization mechanism 3, when installing the junction box 317, manually push the push rod 316 upwards. The push rod 316 simultaneously drives the limiting post 315 upwards. During the upward movement of the limiting post 315, since the limiting post 315 and the limiting frame 314 have inclined slots at their corresponding positions, the upward movement is achieved. During the movement, the limiting frame 314 is pushed to the right, causing the limiting frame 314 to synchronously drive the first locking block 311 to move to the right. Simultaneously, as the limiting frame 314 moves to the right, the synchronizing rod 321 is pushed to the right, and as the synchronizing rod 321 moves to the right, the adjusting column 322 moves to the right. This, in turn, causes the adjusting frame 323 to rotate around the connection point of the junction box 317, thereby synchronously driving the second adjusting column 324 to the left. The movement of the adjustment column 324 synchronously pulls the locking block 326 to the left, thereby completely disengaging the locking block 311 and the locking block 326 from the locking adjustment frame 6. Then, by pushing the junction box 317 up or down to move it to other positions, the locking block 311 and the locking block 326 are reset to complete the fixation of the junction box 317. This allows for rapid changes in the position of the junction box 317. When the number of junction boxes increases, the above operation is used to fix the junction box 317.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
