DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-12 A detachable combined cabinet and an assembly method include a combined cabinet 1, wherein the combined cabinet 1 includes a plurality of middle unit cabinets 11 and end unit cabinets 12 and an assembly 15 for combining the plurality of middle unit cabinets 11 and the end unit cabinets 12 together, wherein the plurality of end unit cabinets 12 are respectively arranged at the top and the bottom of the middle unit cabinet 11, and the number of the end unit cabinets 12 can be 0 or plural. When the number of the end unit cabinets 12 is 0, the top plate 152 and the bottom plate 153 can be installed at the top and the bottom of the middle unit cabinet 11.

[0041] The middle unit cabinet 11 includes at least four column profiles 111 and three side panels 112 and a door panel 113 arranged between the four column profiles 111.

[0042] The end unit cabinet 12 includes at least four column profiles 121 , three side panels 122 and one door panel 123 disposed between the four column profiles 121 .

[0043] The column profile 1 111 and the column profile 2 121 have the same structure, and grooves 13 are provided on four sides of the column profile 1 111 and the column profile 2 121 .

[0044] The assembly 15 includes a profile connector 151 , a top plate 152 and a bottom plate 153 . The top plate 152 is disposed on the top of the modular cabinet 1 , and the bottom plate 153 is disposed on the bottom of the modular cabinet 1 .

[0045] The profile connector 151 is used for connecting the first column profile 111 with the second column profile 121 and for connecting the second column profile 121 with the top plate 152 .

[0046] As a specific technical solution of this embodiment, the shape of the profile connector 151 is the same as that of the column profile 111, but the length and width of the profile connector 151 are slightly smaller than the internal length and width of the column profile 111. The column profile 1 111 and the column profile 2 121 are jointly sleeved with the profile connector 151, and the profile connector 151 is fixed to the column profile 1 111 and the column profile 2 121 by screws.

[0047] In the present embodiment, the profile connector 151 has the same shape as the column profile 1 111 and the column profile 2 121, but is smaller in size. When the middle unit cabinet 11 and the end unit cabinet 12 are connected, the two ends of the profile connector 151 are respectively inserted into the relative column profile 1 111 and the column profile 2 121, and then screws are inserted from the inside of the cabinet to complete the connection and fixation of the profile connector 151 with the column profile 1 111 and the column profile 2 121. Since the screws face the inside of the cabinet, the screws cannot be seen from the outside of the middle unit cabinet 11 and the end unit cabinet 12, making the appearance of the modular cabinet 1 more beautiful and simple.

[0048] As a specific technical solution of this embodiment, the top, bottom and both ends of the side panel 112 are all provided with a folded edge 114, and the top, bottom and both ends of the side panel 2 122 are all provided with a folded edge 124. The folded edges 114 at both ends of the side panel 112 are respectively inserted into the grooves 13 of the column profile 111 at both ends of the side panel 112 and are fixed to the grooves 13 by screws, and the folded edges 124 at both ends of the side panel 2 122 are respectively inserted into the grooves 13 of the column profile 121 at both ends of the side panel 2 122 and are fixed to the grooves 13 by screws.

[0049] In this embodiment, since the middle unit cabinet 11 is located in the middle position of the modular cabinet 1, the top and bottom of the side panel 112 need to avoid the folded edges at the top and bottom of the side panel 2 122, so that only the two ends of the side panel 112 are provided with folded edges 114 to connect with the groove 13, and after the middle unit cabinet 11 is connected to the end unit cabinet 12, the folded edges 124 at the top and bottom of the side panel 2 122 will extend to the inner side of the middle unit cabinet 11, and the connection between the side panel 112 and the side panel 2 122 will be blocked, thereby further ensuring the overall structural strength of the product, and at the same time greatly increasing the sealing of the interior of the cabinet, thereby preventing dust from entering the interior of the cabinet through the connection between the side panel 112 and the side panel 2 122. Figure 5 The folded edge 114 and the folded edge 124 are adapted to the width of the groove 13, ensuring the stability of the folded edge 114 and the folded edge 124 after being inserted into the groove 13. The folded edge 114 and the folded edge 124 are further tightened and fixed by screws, so that the assembly between the side panels 112 and the side panels 122 and the column profiles 111 and the column profiles 121 is more stable and will not shake.

[0050] As a specific technical solution of this embodiment, one end of the door panel 113 is hinged to one side of one of the column profiles 111 through a hinge 14, and one end of the door panel 2 123 is hinged to one side of one of the column profiles 121 through a hinge 14, and the door panel 113 and the door panel 2 123 are fixed by screws.

[0051] In the present embodiment, when the middle unit cabinet 11 and the end unit cabinet 12 are combined, if the middle unit cabinet 11 and the end unit cabinet 12 need to be used as a whole, the connection between the door panel 113 and the door panel 2 123 can be fixed together with screws. If the middle unit cabinet 11 and the end unit cabinet 12 need to be used independently, there is no need to connect the door panel 113 and the door panel 2 123 together, and door locks 156 can be installed on each independently opened door panel 113 and door panel 2 123 to lock them independently.

[0052] As a specific technical solution of this embodiment, both ends of the door panel 113 are provided with edges 115, and the top and bottom of the door panel 113 are provided with bends 116. The edges 115 at both ends of the door panel 113 are respectively inserted into the grooves 13 of the column profiles 111 at both ends of the door panel 113. Both ends of the door panel 123 are provided with edges 125, and the top and bottom of the door panel 123 are provided with bends 126. The edges 125 at both ends of the door panel 123 are respectively inserted into the grooves 13 of the column profiles 121 at both ends of the door panel 123. The connection between the door panel 113 and the door panel 2 123 is fixed by screws to fix the bend 116 and the bend 126.

[0053] In this embodiment, the groove 13 can make way for and bury the edges of the door panel 1 113 and the door panel 2 123 so that there is no prying point on the buried edges. The limiting function of the groove 13 can also protect and prevent the prying of the door panel 1 113 and the door panel 2 123, thereby ensuring the safety of the modular cabinet 1.

[0054] As a specific technical solution of this embodiment, profile connectors 151 are welded to the four corners of the bottom of the top plate 152. The bottom end of the profile connector 151 at the bottom of the top plate 152 is inserted into the topmost column profile 121 and fixed to the column profile 121 by screws. The top plate 152 is fixed to the top of the topmost side plate 122 by screws.

[0055] In the present embodiment, the design of welding and fixing the top plate 152 and the profile connector 151 ensures the assembly stability of the top plate 152, and after the profile connector 151 at the bottom of the top plate 152 is fixed to the column profile 121, the folded edge at the bottom of the top plate 152 and the folded edge at the top of the side panel 122 are screwed together, further ensuring the assembly stability of the top plate 152, and the folded edge 124 at the top of the side panel 122 extends to the interior of the top plate 152, ensuring the sealing of the connection between the side panel 122 and the top plate 152.

[0056] As a specific technical solution of this embodiment, the bottom plate 153 is fixed to the bottom of the lowest side plate 122 by screws, and profile holes 154 are opened inside the four corners of the bottom plate 153, and the four profile holes 154 are respectively opposite to the bottom ends of the four lowest column profiles 121.

[0057] In this embodiment, after the bottom plate 153 and the second side plate 122 are fixed by screws, the folded edge 124 at the bottom of the second side plate 122 extends to the inner side of the bottom plate 153, ensuring the sealing of the connection between the second side plate 122 and the bottom plate 153. The profile hole 154 is used to avoid the support foot 155, which facilitates the installation of the support foot 155.

[0058] As a specific technical solution of this embodiment, the assembly 15 also includes a support leg 155 and a door lock 156. The support leg 155 has the same shape as the profile connector 151. The top of the support leg 155 passes through the profile hole 154 and extends to the interior of the column profile 121. A plurality of lifting adjustment holes 1551 are provided on both sides of the support leg 155. The support leg 155 and the column profile 121 are fixed by screws through the lifting adjustment holes 1551. A support plate 157 is fixed to the bottom end of the support leg 155.

[0059] In this embodiment, the support leg 155 passes through the profile hole 154 and enters the interior of the column profile 121. The height of the support leg 155 can be adjusted through multiple lifting adjustment holes 1551. After the adjustment is completed, the screw is screwed into the corresponding lifting adjustment hole 1551 to complete the fixation between the support leg 155 and the column profile 121.

[0061] In the present embodiment, after the door panel 113 and the door panel 2 123 are fixed together, it is only necessary to install the door lock 156 on one of the door panels 113 or the door panel 2 123. The specific position is determined according to the height of the modular cabinet 1, mainly for the convenience of the user to open it. The door lock 156 can be an electronic lock or a conventional key lock. The latch 1561 inside the latch assembly 1561 can be controlled by a password or a key through the latch control panel 1562 to disengage from the latch slot 1563 or enter the latch slot 1563 to achieve unlocking and locking.

[0062] A method for assembling a detachable combined cabinet comprises the following steps:

[0063] To assemble the middle unit cabinet 11, first drill screw holes in the two grooves 13 of the folded edges 114 at both ends of the side panel 112 and the column profile 111 facing the inside of the cabinet, and then fix the side panel 112 and the column profile 111 through the screw holes. Where screw holes are needed, rivet nuts can be drawn on the through holes;

[0064] To assemble the end unit cabinet 12, first drill screw holes in the two grooves 13 of the folded edges 124 at both ends of the side panel 122 and the column profile 121 facing the inside of the cabinet, and then fix the side panel 122 and the column profile 121 with screws through the screw holes;

[0065] On the assembled modular unit cabinet, screw holes corresponding to the column profile 1 111 and the column profile 2 121 are opened on the profile connector 151, and the profile connector 151 is inserted into the column profile 1 111 and the column profile 2 121 of the middle unit cabinet 11 and the end unit cabinet 12, and screws are inserted through the screw holes to complete the docking of the column profile 1 111 and the column profile 2 121, and then screw holes are opened at the overlapping parts of the side panels 1 112 and 122 and screws are inserted to fix them;

[0066] In the assembled modular unit cabinet, four profile connectors 151 are welded at the bottom of the top plate 152, and the bottom ends of the profile connectors 151 are inserted into the topmost column profile 121 and fixed by screws. Screw holes are opened on the bottom folded edge of the top plate 152, and the top plate 152 and the top of the top side plate 122 are fixed by screws through the screw holes. Screw holes are opened on the top folded edge of the bottom plate 153, and the bottom plate 153 and the bottom of the bottom side plate 122 are fixed by screws through the screw holes.
