It will be appreciated that when the top and bottom hinges 3 are provided at both ends of the edging 25, the sum of the length D of the edging 25 and the length D of the two hinge bases 33 is equal to the length of the vertical frame 3 of the hinge; the phenomenon that the upper and lower hinges 3 exceed the edge of the door frame 2 after the upper and lower hinges 3 are arranged is avoided, and the material is saved and the door frame is attractive.

In some alternative embodiments, with continued reference to fig. 2 and 3, the length of the fixed base 31 is greater than the length of the hinge base 33 in the direction of the top plate 11 toward the bottom plate 13.

Specifically, fig. 2 only shows the lower left hinge for schematic illustration, and at this time, the length of the fixed base 31 is in the same plane with the bottom of the hinge base 33, and the hinge base 33 is lengthened in a direction away from the bottom plate 13, so that the length 31 of the fixed base is greater than the length of the hinge base 33; similarly, the length of the fixed base 31 of the upper left hinge is in the same plane as the top of the hinge base 33, and the hinge base 33 is lengthened in a direction away from the top plate 11 so that the length 31 of the fixed base is greater than the length of the hinge base 33.

It will be appreciated that the length of the fixed base 31 is large, increasing the contact area of the fixed base 31 with the top and bottom plates 11, 13 makes the connection more secure.

It will be appreciated that when the length of the fixed base 31 is greater than the length of the hinge base 33 in the direction in which the top plate 11 is directed toward the bottom plate 13, the length of the end of the connecting bar 32 connected to the fixed base 31 is greater than the length of the end of the connecting bar 32 connected to the hinge base 33, i.e., the length of the first end 321 is greater than the length of the second end 322. The length of the first end 321 is large, and the contact area between the connecting strip 32 and the fixed base 31 is increased, so that the connection is more fastened.

In some alternative embodiments, with continued reference to FIG. 3, the tie bars 32 are right angle trapezoidal shaped tie bars.

It will be appreciated that the connecting strip 32 is a right trapezoid connecting strip, and the length of the end of the connecting strip 32 connected with the fixed base 31 is longer than the length of the end of the connecting strip 32 connected with the hinge base 33, so that the contact area between the connecting strip 32 and the fixed base 31 is increased to enable the connection to be more secure.

In some alternative embodiments, with continued reference to fig. 5 and 6, a groove 252 is provided at the intersection of the side of the edging 25 remote from the handle upright frame 24 and the side of the edging 25 proximate to the hinge upright frame 22.

It will be appreciated that, when the connecting strip 32 is a right trapezoid connecting strip, since the length of the end of the connecting strip 32 connected with the fixed base 31 is longer than that of the end of the connecting strip 32 connected with the hinge base 33, a groove 252 needs to be formed at the intersection of the side of the receiving strip 25 away from the handle vertical frame 24 and the side of the receiving strip 25 close to the hinge vertical frame 22, so that the end of the connecting strip 32 connected with the fixed base can penetrate through the groove 252 of the hinge vertical frame 22 to be connected with the top plate 11 and the bottom plate 13, and deformation caused by collision between the connecting strip 32 and the hinge vertical frame 22 is avoided.

In some alternative embodiments, with continued reference to fig. 3, the width of the fixed base 31 is greater than the width of the hinged base 33 in a direction perpendicular to the plane of the connecting strip 32.

It will be appreciated that the large width of the mounting base 31 increases the contact area of the mounting base 31 with the top and bottom plates 11, 13 to provide a more secure connection. Meanwhile, the width of the fixed base 31 is large, correspondingly, the width of the protruding part 34 is large, a plurality of through holes 35 can be formed in the protruding part 34 according to actual requirements, the fixed base 31 and the top plate 11 are fixedly connected through a plurality of screws, and the connection is more stable.

In some alternative embodiments, referring to fig. 5 and 10, the handle vertical frame 24 is provided with an L-shaped handle bar 26 protruding from the handle vertical frame 24 in a direction perpendicular to the plane of the door frame 2.

It should be noted that, along the direction perpendicular to the plane of the door frame 2, the thickness of the handle bar 26 is not greater than the thickness of the edging 25, that is, the thickness of the handle bar is less than or equal to the thickness of the edging 25, so as to avoid the collision with the core boards of the side cabinets after the door frames 2 are arranged side by side and opened.

It will be appreciated that the handle vertical rim 24 is provided with an L-shaped handle bar 26 protruding from the handle vertical rim 24 to allow the handle vertical rim 24 to be self-locking to the handle slot. When the cabinet is additionally provided with the handle, the thickness of the handle is larger than that of the edge folding strip 25, and when the door frames of the plurality of cabinets are arranged side by side to open 180 degrees, the additionally provided handle can collide with the core plate of the side cabinet; the handle vertical frame 24 does not need to be additionally provided with a handle from the handle buckling groove, so that the glass core plate is prevented from being broken due to collision with the core plate.

In some alternative embodiments, with continued reference to FIG. 4, a spacer 38 is also provided between the screw 36 and the tab 34.

Specifically, in fig. 4, only the area of the spacer 38 is equal to the area of the hollowed-out area 37 as an example, the spacer 38 may be disposed only at the position of the screw 36, so that the area of the spacer 38 is equal to the area of the screw 36. It should be noted that, the spacer 38 may be a flat spacer, and increasing the contact area between the screw 36 and the protrusion 34 makes the connection more secure; the spacer 38 may also be a resilient spacer that reduces friction between the screw 36 and the tab 34 and also provides a release preventing effect.

According to the embodiment, the cabinet capable of being opened and closed at a large angle provided by the utility model has the following beneficial effects:
