[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 4 A PLC controller that is easy to install includes: a fixed plate 2; two snap-fit ​​components 3 arranged opposite each other on the outer surface of the fixed plate 2 and a support edge 4 slidably connected to the outer surface of the fixed plate 2; the snap-fit ​​components 3 and the support edge 4 together clamp the controller body 1; the rear surface of the fixed plate 2 is provided with a snap-fit ​​edge 8 and a fixing component 9, and a fixing rail 7 is provided at the rear of the fixed plate 2; the fixed plate 2 is fixed to the fixing rail 7 through the snap-fit ​​edge 8 and the fixing component 9.

[0025] The snap-fit ​​assembly 3 includes a snap-fit ​​sleeve 31, the snap-fit ​​sleeve 31 has a square moving groove 33 inside, a lifting block 32 is sleeved inside the moving groove 33, the lifting block 32 is obliquely cut, a first spring 34 is provided inside the moving groove 33, the other end of the first spring 34 is fixedly connected to the lifting block 32, and is used to move the lifting block 32 upward; the lifting block 32 snaps into the inner wall of the through hole provided on the rear side of the controller body 1;

[0026] The snap-fit ​​assembly 3 also includes a slider 35. The fixing plate 2 has a first groove 5 inside, and the slider 35 is slidably connected to the inner wall of the first groove 5.

[0027] The outer wall of the fixing plate 2 is provided with a second sliding groove 6. The support along the rear wall of the 4 is slidably connected to the inside of the second sliding groove 6. The support along the inner wall of the 4 is threaded with a positioning screw 10. The end of the positioning screw 10 is in fixed contact with the fixing plate 2.

[0028] The fixing component 9 includes a fixing shell 91, which is fixedly connected to the rear wall of the fixing plate 2. The fixing shell 91 has multiple limiting grooves 93 inside, and a moving block 92 is sleeved inside the limiting groove 93.

[0029] The technical solution provided in this embodiment is as follows: In use, firstly, the distance between the two snap-fit ​​components 3 is adjusted to a suitable position. Then, the controller body 1 is placed above the fixing plate 2. Next, the fixing through hole at the rear of the controller body 1 is pushed into the snap-fit ​​component 3. When pushed in, the inclined lifting block 32 moves downward after being subjected to the force of the controller body 1. When the position of the through hole coincides with the position of the lifting block 32, the lifting block 32 will pop up under the action of the first spring 34, fixing one corner of the controller body 1. After both snap-fit ​​components 3 are fixed to the controller body 1, the support edge 4 is pushed so that the support edge 4 contacts the controller body 1. Then, the support edge 4 is fixed to the fixing plate 2 by the positioning screw 10. After the controller body 1 is fixed, the snap-fit ​​edge 8 is placed above the fixing rail 7 and then pushed inward. When pushed, the moving block 92 moves downward to compress the second spring 94. When the moving block 92 is fully snapped into the fixing rail 7, the moving block 92 pops up under the action of the second spring 94, fixing the fixing plate 2, thus completing the installation of the device.

[0030] Furthermore, the support along line 4 has a "Z" shaped structure, which is used to snap onto the rear edge of the controller body 1.

[0031] Specifically, the support edge 4 of the "Z"-shaped structure can effectively support the controller body 1 and can be engaged with the rear wall of the controller body 1 to prevent the controller body 1 from swaying during use.

[0032] Furthermore, the fixing component 9 also includes a second spring 94, which is disposed inside the limiting groove 93, and the other end of the second spring 94 is fixedly connected to the moving block 92.

[0033] Specifically, by setting the second spring 94, the moving block 92 can be moved upward quickly during the snap-fit ​​process, making the installation faster.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
