[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1-8 As shown in the embodiment of this application, a detachable cabinet is disclosed, including a base 1. Four rectangular mounting brackets 2 extending vertically are detachably connected to the base 1. The top of the four mounting brackets 2 is connected to a top cover plate 3 to form a mounting frame. Side plates 4 are detachably connected between the two mounting brackets 2 on the left and right sides of the mounting frame. Front doors 5 and rear doors 6 that can be opened and closed are respectively connected between the two mounting brackets 2 on the front and rear sides of the mounting frame. More specifically, a control panel is also provided at the upper end of the front door 5 for controlling the electrical control equipment 20 inside the cabinet. In addition, at least one vertically extending mounting channel 8 is provided on each of the four mounting brackets 2 for accommodating nuts 7. An opening slot 9 communicating with the mounting channel 8 is provided on the mounting bracket 2 for the connecting screw 10 on the control equipment 20 to pass through until it is connected to the nut 7.

[0030] In the above structure, hinge shafts are respectively provided at the upper and lower ends of one side of the front door 5 and the rear door 6 in the width direction to realize the rotational connection with the upper cover plate 3 and the base 1. Specifically, the lower hinge shaft is a fixed pin and the upper hinge shaft is a spring pin, which facilitates disassembly and assembly. The other side of the front door 5 and the rear door 6 in the width direction is connected to the corresponding mounting bracket 2 through a door lock, thereby realizing the opening and closing of the front door 5 and the rear door 6.

[0031] In this embodiment, see Appendix Figure 2 , 3 Preferably, the openings of the slots 9 on the two mounting brackets 2 on the front side of the mounting frame face forward, and the openings of the slots 9 on the two mounting brackets 2 on the rear side of the mounting frame face backward. Therefore, after the main body of the cabinet is assembled, when the control equipment 20 needs to be installed, the front door 5 or the rear door 6 is opened, and the corresponding equipment 20 is installed horizontally. Multiple connection through holes are reserved on the equipment 20. Generally, a fixing plate is set on the outer wall of the equipment 20 near the door panel. Two connection through holes are opened at both ends of the fixing plate, that is, each equipment 20 is provided with four connection through holes. During installation, the nut 7 is first placed into the installation channel 8, ensuring that the through hole of the nut 7 corresponds to the opening of the slot 9. Then, the corresponding connecting screws 10 are inserted into the four connection through holes. The connecting screws 10 at both ends of the fixing plate pass through the corresponding slots 9 and connect to the nut 7 to realize the connection between the equipment 20 and the cabinet. The installation height of the equipment 20 can be adjusted in real time by moving the position of the nut 7 up and down, which is very convenient.

[0032] More specifically, in this embodiment, to facilitate the connection and fixing of the connecting screws 10 on the mounting bracket 2, multiple nuts 7 are pre-set in each mounting channel 8, and the positions of the nuts 7 in the mounting channel 8 can be adjusted vertically. Thus, when fixing the device 20, simply adjust the position of the nuts 7 according to the actual required positioning height of the device 20, and then screw the connecting screws 10 in the connecting through holes on the device 20 through the opening slots 9 and into the inner holes of the corresponding nuts 7. See Appendix for details. Figure 4 Each nut 7 has an annular mounting groove on its outer peripheral wall. A rubber ring 11 is fitted into the mounting groove, and the rubber ring 11 is interference-fitted with the inner wall of the mounting channel 8. With this setting, the nut 7 will not move up and down on its own in the mounting channel 8. When the position needs to be adjusted, a certain external force needs to be applied to it to deform the rubber ring 11 and move the nut 7. In this way, when fixing the equipment 20, the nut 7 will remain stationary after being adjusted to the corresponding height, which makes it easier to connect the screw 10.

[0033] In this embodiment, the mounting bracket 2 includes a flattened column body 12, and a mounting plate 13 perpendicular to it is provided protruding outward on one side wall of the column body 12.

In addition, the mounting plates 13 of the two mounting brackets 2 on the left side of the mounting frame extend to the right, and the mounting plates 13 of the two mounting brackets 2 on the right side of the mounting frame extend to the left. The mounting channel 8 is provided on each mounting plate 13. The front side wall of the mounting plates 13 of the two mounting brackets 2 on the front side of the mounting frame and the rear side wall of the mounting plates 13 of the two mounting brackets 2 on the rear side of the mounting frame are provided with opening slots 9 to facilitate the installation and fixation of the equipment 20 from the front door 5 position or the rear door 6 position.

[0034] See appendix for further details. Figure 3 and 7 The base 1 has positioning slots 14 on the upper surfaces of both sides. Locking components 15 are connected to the front and rear opposite side walls of the two mounting brackets 2 on both sides of the mounting frame. Positioning inserts 16 that engage with the corresponding positioning slots 14 are provided at the lower ends of the two side plates 4. Locking buckles 17 that are detachably connected to the corresponding locking components 15 are connected to both sides of the upper end of each side plate 4. More specifically, the locking components 15 in this structure include sheet metal parts connected to the column body 12. Locking grooves 21 are machined on the sheet metal parts, and the locking buckles 17 can be engaged in the locking grooves 21 to achieve locking. Preferably, the locking buckles 17 are made of plastic and can deform elastically, facilitating engagement and disengagement with the locking grooves 21.

[0035] In addition, in this embodiment, all four mounting brackets 2 are made of aluminum profiles, and each mounting bracket 2 has multiple connecting holes formed at both its upper and lower ends. Multiple connecting screws 10 for connecting to the corresponding connecting holes are connected to the four corners of the upper cover plate 3 and the base 1. The mounting bracket 2 is detachably connected to the base 1 and the upper cover plate 3 through the cooperation of the connecting screws 10 and the connecting holes, which is very convenient. Specifically, to ensure the accuracy of the connection position between the four mounting brackets 2 and the base 1, positioning pins are pre-installed on the base 1 at the corresponding positions of each mounting bracket 2. Correspondingly, corresponding positioning holes are pre-formed on the bottom of the mounting bracket 2. During installation, the bottom of the mounting bracket 2 is first inserted into the corresponding positioning pin on the base 1 for positioning, and then the connecting screws 10 are installed from below the base 1.

[0036] Preferably, both the top cover plate 3 and the base 1 are made of sheet metal using a bending process, which is convenient to process, aesthetically pleasing, and lighter than conventional welded iron plate structures. Furthermore, in this embodiment, the side panels 4 and door panels are made of aluminum alloy to minimize the overall weight and facilitate transportation. In addition, except for necessary disassembly points, all other components are reinforced by welding to enhance the overall shock resistance of the cabinet.
