Technical Field

[0001] The utility model relates to the technical field of PLC controller shells, in particular to a PLC controller shell assembly which is not easily misplaced during installation. Background Art

[0002] The PLC controller housing assembly provides a physical barrier to protect the electronic components inside the PLC controller from the external environment. The PLC controller housing assembly plays an important role in protecting internal components, heat dissipation, installation and fixation, electromagnetic shielding, identification protection, and aesthetics.

[0003] Most existing PLC controller housings consist of two parts: a shell and a cover. The cover is vertically aligned with the top of the shell and then connected with bolts. However, due to the lack of restrictions on the position of the cover during installation, the cover often moves during installation, resulting in misalignment. This not only consumes a lot of time but also reduces installation efficiency.

[0004] Therefore, those skilled in the art provide a PLC controller housing assembly that is not easily misplaced during installation, so as to solve the problems raised in the above background technology. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-5 The utility model provides an embodiment of a PLC controller housing assembly that is not easy to be dislocated, including a housing 1 and a housing cover 2. Both sides of the top inner wall of the housing 1 are provided with sliding grooves 9, and the housing cover 2 is slidably clamped on the top of the housing 1. An iron sheet 8 is glued on one side of the inner wall of the housing 1, and a fixing groove 6 is opened on one side of the top of the housing cover 2. A magnetic sheet 7 is inlaid inside the fixing groove 6. By providing sliding grooves 9 at both ends of the top of the housing 1, the housing cover 2 is slidably clamped on the top of the housing 1, so that the horizontal position of the housing cover 2 to be installed is preliminarily fixed, and then an iron sheet 8 is glued on one side of the inner wall of the housing 1, and a fixing groove 6 is opened on one side of the top of the housing cover 2. A magnetic sheet 7 is inlaid inside the fixing groove 6. The magnetic sheet 7 attracts the iron sheet 8 to fix the longitudinal position of the housing cover 2, which solves the problem that there is no restriction on the position of the housing cover 2 during the installation process of the existing PLC controller housing, and the housing cover 2 often moves during the installation process, resulting in installation dislocation.

[0033] A fixing plate 12 is installed on the side of the housing 1 away from the iron sheet 8, and a hinge shaft 14 is fixedly provided on one side of the top of the fixing plate 12. A limit plate 15 is provided in the middle of the hinge shaft 14 for rotation. A return spring 16 is provided at the bottom end of the limit plate 15 and connected to the top side of the fixing plate 12. By fixing the hinge shaft 14 on one side of the top of the fixing plate 12, and rotating the limit plate 15 in the middle of the hinge shaft 14, the return spring 16 is provided by pressing the limit plate 15 so that its bottom end is connected to the top side of the fixing plate 12. 16 is compressed, and when the shell cover 2 is initially fixed, the limit plate 15 is released, and the limit plate 15 is reset by the rebound force of the reset spring 16. Since the installation height of the limit plate 15 is greater than the shell 1, the limit plate 15 after reset can further limit the position of the shell cover 2, thereby enhancing the stability of the shell cover 2. The top four corners of the shell 1 are provided with fixing holes 4, and the top four corners of the shell cover 2 are provided with half-body holes 3. The hole 3 is convenient for protecting the bolt head of the connecting bolt 5. A connecting bolt 5 is connected between the fixing hole 4 and the half-body hole 3 at the same vertical position, and a connecting bolt 5 is connected between the fixing hole 4 and the half-body hole 3 at the same vertical position, which is convenient for installing the shell cover 2 on the top of the shell 1. Mounting holes 11 are provided in the middle ends of the four side surfaces of the shell 1, and multiple ventilation holes 10 are provided on both sides of the shell 1. Mounting holes 11 are provided in the middle ends of the four side surfaces of the shell 1. Multiple ventilation holes 10 are provided on both sides of the shell 1 to facilitate ventilation and heat dissipation of the shell 1. The iron sheet 8 and the magnetic sheet 7 are located at the same end, and the iron sheet 8 and the magnetic sheet 7 can attract each other. The iron sheet 8 and the magnetic sheet 7 are located at the same end, and the iron sheet 8 and the magnetic sheet 7 can attract each other, which is convenient for fixing one end of the shell 1. A pair of fixing bolts 13 are fixed at the fitting position of the fixing plate 12 and the shell 1. A pair of fixing bolts 13 are fixed at the fitting position of the fixing plate 12 and the shell 1 to facilitate the installation of the fixing plate 12.

[0034] Working principle: By opening a slide groove 9 at both ends of the top of the shell 1, the shell cover 2 is slidably clamped on the top of the shell 1, thereby preliminarily fixing the horizontal position of the shell cover 2 to be installed, and then an iron sheet 8 is adhered to one side of the inner wall of the shell 1, and a fixing groove 6 is opened on one side of the top of the shell cover 2. A magnetic sheet 7 is embedded in the fixing groove 6. The magnetic sheet 7 attracts the iron sheet 8 to fix the longitudinal position of the shell cover 2, which solves the problem of lack of position restriction of the shell cover 2 during the installation process of the existing PLC controller shell, and the shell cover 2 often moves and then leads to the problem of the shell cover 2 being damaged during the installation process. In order to solve the defect of installation misalignment, a hinge shaft 14 is fixed on the top side of the fixed plate 12, and a limit plate 15 is rotatably set in the middle of the hinge shaft 14. By pressing the limit plate 15, the reset spring 16 connected to the bottom end of the fixed plate 12 is compressed. After the shell cover 2 is initially fixed, the limit plate 15 is released and the limit plate 15 is reset by the rebound force of the reset spring 16. Since the installation height of the limit plate 15 is greater than the shell 1, the limit plate 15 after reset can further limit the position of the shell cover 2, thereby enhancing the stability of the shell cover 2.
