During the installation of the cabinet door 70 and the first hinge bracket 30, the hinge post 73 protrudes to a certain extent from the inner side of the hinge plate 33, and this protruding part falls into the groove of the first hinge bracket 30, and the groove-shaped structure provides enough space for the installation of the hinge post 73 and protects the protruding part of the hinge post 73 after the installation. The hinge post 73 may be connected to the hinge plate 33 on the upper side of the base plate 32 or to the hinge plate 33 on the lower side of the base plate 32, i.e., the cabinet door 70 may be located above the first hinge frame 30 or below the first hinge frame 30.
Specifically, as to the second hinge frame 40, as shown in fig. 5, the second hinge frame 40 includes a veneer 41, a folded plate 42, a connecting plate 43, and a fixing plate 44 in this order, and the side cross section of the second hinge frame 40 is formed in a stepped shape after the four are connected, and the width of the first hinge frame 30 is gradually increased from the veneer 41 to the fixing plate 44, and the veneer 41 is completely adhered to the partition 20, and the width thereof is identical to the width in the partition 20. The folded plate 42 comprises two parts, one part is positioned in the partition 20, the other part extends out of the partition 20, the outline of the folded plate 42 which is sunk into the partition 20 is rectangular, the width of the folded plate is consistent with the width of the flitch 41, the outline of the folded plate 42 which extends out of the partition 20 is trapezoid, and one end far away from the partition 20 is a long side of the trapezoid. The flap 42 forms an angle with the pasting plate 41 and extends to the rear side of the partition 20 in order to smoothly fix the fixing plate 44 connected thereto to the bracket 10. The connection plate 43 has a trapezoid shape. The profile of the fixing plate 44 is trapezoid, one side of the fixing plate 44 connected with the folded plate 42 is a short side of the fixing plate 44, the fixing plate 44 is fixed on the bracket 10, and the trapezoid structure enables the fixing plate 44 to have a larger space for assembling with the bracket 10, so that the stability of connection between the second hinge bracket 40 and the bracket 10 is further improved.
Regarding the assembly of the first hinge frame 30, the partition board 20, and the second hinge frame 40, see fig. 1, 2, and 4, a first assembly hole 321 is formed in the first hinge frame 30, a second assembly hole 421 is formed in the second hinge frame 40, a third assembly hole is formed in the partition board 20, and the first fixing bolt 50 sequentially passes through the first assembly hole 321, the second assembly hole 421, and the third assembly hole to be fixed. In this embodiment, the first assembly hole 321, the second assembly hole 421 and the third assembly hole are all round holes, the first fixing bolt 50 is a structure of matching a bolt with a nut, and a screw portion of the bolt sequentially passes through the first assembly hole 321, the third assembly hole and the second assembly hole 421 until the head of the bolt abuts against the bottom plate 32 of the first hinge bracket 30, and then is fastened by the nut matched with the bolt, so that the first hinge bracket 30, the partition plate 20 and the second hinge bracket 40 are fixedly connected.
However, it is conceivable that the first hinge bracket 30 may be rotated about a bolt as an axis if it is fixed by only one bolt and a bolt hole, thereby affecting the assembly of the cabinet door 70, and thus, as a preferred embodiment, the partition 20 is provided with a positioning hole, the bottom plate 32 is provided with a positioning protrusion 31 engaged with the positioning hole, and the positioning protrusion 31 is recessed into the positioning hole. Thus, after assembly, at least two fixed assembly points exist between the first hinge bracket 30 and the partition board 20, so that rotation phenomenon can not occur, and the stability of subsequent assembly with the cabinet door 70 is further ensured.

As can be seen from the foregoing description, the end of the fixing plate 44 away from the folded plate 42 is a wider end, which has enough contact area with the bracket 10, so that the second mounting holes 441 can be provided on the bracket 10 and matched with the first mounting holes 111, as can be seen from the figure, the number of the second mounting holes 441 on the fixing plate 44 is a plurality, and the second fixing bolt 60 is also in a bolt and nut matched structure. After assembly, the nut is attached to the fixing plate 44, and the direction of assembly is selected so as to avoid that the redundant portion of the screw of the bolt is exposed to the outside of the bracket 10, which affects the aesthetic appearance, and the screw may collide with the user, thereby causing a problem of safety.
In this embodiment, the partition 20 is a cross plate mounted on the bracket 10, and its edge is folded over so as to form a sufficient contact area with the bracket 10, and is further fixed to the bracket 10 by the portions which are brought into contact with the bracket 10 after these folding-over. Specifically, the upper and lower ends of the partition board 20 are provided with folded edges turned back, and the width of the flitch 41 is identical to the width of the inner side of the partition board 20. The presence of the folds allows the partition 20 to form a channel-type structure, the width of the inner side of which is defined, and the width of the panel 41 is identical to the width of the inner side of the partition 20, so that after the panel 41 is attached to the partition 20, the position is defined by the folds on the upper and lower sides, and no upward and downward movement occurs, which also allows the first hinge frame 30 connected to the second hinge frame 40 to be further fixed.
