[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] This utility model embodiment provides a quick-release PLC module structure, such as Figures 1-3As shown, the system includes a mounting plate 1 and a PLC module 2. The mounting plate 1 is installed inside the control box. Both sides of the top of the mounting plate 1 have strip-shaped slots 11. The bottom of the PLC module 2 is fitted with a locking plate 3, which is respectively locked into the slots 11 on both sides of the top of the mounting plate 1. The PLC module structure also includes a locking assembly 4, which includes a fixing sleeve 41 mounted on the locking plate 3. A connecting rod 42 is movably mounted inside the fixing sleeve 41. A positioning block 43 is mounted on the lower end of the connecting rod 42. One end of the mounting plate 1 has a positioning groove 12 that matches the positioning block 43. The positioning block 43 is connected to the fixing sleeve 41 by an elastic element 44. A limiting block 45 is provided at the upper end of the connecting rod 42. An adjusting sleeve 46 is provided between the limiting block 45 and the fixing sleeve 41, and the adjusting sleeve 46 is fitted onto the connecting rod 42. The top of the 41 is provided with a first concave-convex structure 411, and the bottom of the adjusting sleeve 46 is provided with a second concave-convex structure 461 that cooperates with the first concave-convex structure 411. Through the cooperation of the first concave-convex structure 411 and the second concave-convex structure 461, the adjusting sleeve 46 can be rotated to raise and lower the adjusting sleeve 46. The adjusting sleeve 46 can drive the limiting block 45 to rise and fall. The limiting block 45 can drive the positioning block 43 to rise and fall through the connecting rod 42, so that the positioning block 43 can be fixed inside the positioning groove 12 or removed from the positioning groove 12. At the same time, the card plate 3 can be inserted into the strip card slot 11 or pulled out from the strip card slot 11. The operation is convenient, so the PLC module 2 can be easily installed inside the control box or removed from the control box. This makes it convenient to repair the PLC module 2 when it malfunctions, thus improving the repair efficiency of the PLC module 2.

[0018] It should be noted that the first concave-convex structure 411 includes a first protrusion and a first groove on the top of the fixed sleeve 41, and the first protrusion and the first groove are smoothly transitioned. The second concave-convex structure 461 includes a second protrusion and a second groove on the bottom of the adjusting sleeve 46, and the second protrusion and the second groove are smoothly transitioned. When the adjusting sleeve 46 is rotated to the point where the first protrusion and the second protrusion and the first groove and the second groove are opposite each other, the positioning block 43 rises and disengages from the positioning groove 12. When the adjusting sleeve 46 is rotated to the point where the first protrusion and the second groove and the first groove and the second protrusion are opposite each other, the positioning block 43 descends and is fixed inside the positioning groove 12. In addition, in order to facilitate the rotation of the adjusting sleeve 46, the outer wall of the adjusting sleeve 46 is provided with anti-slip ribs.

[0019] It should be noted that the mounting plate 1 has first mounting holes at each of its four corners, which makes it easy to install the mounting plate 1 on the control box; the PLC module 2 has second mounting holes at each of its four corners, and the card plate 3 has third mounting holes at each of its four corners, which makes it easy to install the card plate 3 on the bottom of the PLC module 2.

[0020] In this embodiment, the strip slot 11 is open at one end and closed at the other end. The card plate 3 can be inserted into the strip slot 11 from the open end. When the card plate 3 abuts against the closed end of the strip slot 11, the card plate 3 is locked in place, and at the same time the positioning block 43 is opposite to the positioning groove 12.

[0021] In order to facilitate fixing the positioning block 43 inside the positioning groove 12, in this embodiment, the lower end of the positioning block 43 is a conical structure. However, this utility model is not limited to designing the lower end of the positioning block 43 as a conical structure. For example, in some other embodiments, the lower end of the positioning block 43 is an arc-shaped structure.

[0022] In this embodiment, the elastic element 44 is a spring. When the elastic element 44 is a spring, the spring is sleeved on the connecting rod 42, and the two ends of the spring are in contact with the fixed sleeve 41 and the positioning block 43 respectively but are not fixed. The elastic element 44 of this utility model is not limited to the form of a spring. For example, in some other embodiments, the elastic element 44 is a metal sheet or other elastic object.

[0023] In order to facilitate the installation of the locking component 4 on the card plate 3, in this embodiment, the fixing sleeve 41 is a T-shaped structure, and the card plate 3 is provided with a fixing hole 31. The lower end of the fixing sleeve 41 passes through the fixing hole 31 and is threadedly connected to the first locking nut 47.

[0024] To facilitate the assembly of the locking assembly 4, in this embodiment, the upper end of the connecting rod 42 is provided with a threaded head 421, and the center of the limiting block 45 is provided with a through hole 451 and is sleeved on the threaded head 421. A second locking nut 48 is threadedly connected to the threaded head 421. When assembling the locking assembly 4, the upper end of the connecting rod 42 is passed through the spring, the fixing sleeve 41, the adjusting sleeve 46 and the limiting block 45 in sequence, and locked by the second locking nut 48. The operation is convenient, and the locking assembly 4 can be easily assembled.

[0025] Specific principle: During installation, the mounting plate 1 is installed inside the control box, the clamping plate 3 is installed at the bottom of the PLC module 2, and then the clamping plate 3 is inserted into the clamping groove 11 of the mounting plate 1. After the clamping is completed, the adjusting sleeve 46 is rotated. Under the elastic thrust of the elastic element 44, the positioning block 3 descends and is fixed inside the positioning groove 12, and the installation is completed.

[0026] When PLC module 2 malfunctions and needs maintenance, rotate the adjusting sleeve 46. The adjusting sleeve 46 can drive the limit block 45 to rise. The limit block 45 can drive the positioning block 43 to rise through the connecting rod 42, thereby allowing the positioning block 43 to disengage from the positioning groove 12. After the positioning block 43 disengages from the positioning groove 12, pull the card block 3 out of the strip card groove 11, and the PLC module 3 can be removed from the control box for maintenance.

[0027] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
