[0002] Currently, existing aluminum-framed doors are generally equipped with floor hinges. Prior art (CN216240203U) discloses floor hinges for casement doors that can open 180 degrees. However, when floor hinges are used with heavy aluminum-framed doors, due to the large size and weight of large-format door panels, the upper hinge only serves to limit the door panel's position and does not bear any weight. The entire weight of the door panel falls on the lower hinge, which can gradually tilt or skew over time. The lower pin connecting the lower hinge and the aluminum-framed door is misaligned because the lower hinge axis hole is not aligned with the aluminum frame axis hole.

The upper left hinge and the upper right hinge are connected to the top plate 11, and the lower left hinge and the lower right hinge are connected to the bottom plate 13, and four hinge connecting seats 7 need to be provided accordingly. Figure 3 Only four hinge connection seats 7 are shown for schematic illustration. Figure 2 When the door frame 2 is fully opened, the angle between the upper horizontal frame 21 and the top plate 11 is about 260 degrees, and the angle between the lower horizontal frame 23 and the bottom plate 13 is about 260 degrees; compared with the prior art, the opening angle of the door frame 2 is increased, and the door frame 2 can be folded to the side of the left plate 12 or the right plate 14, which does not occupy the indoor activity space and is not easy to be bumped.
[0052] Reference Figure 5 The hinge connection seat 7 includes a clamping portion 71 and a limiting portion 72. The limiting portion 72 is perpendicular to the plane where the clamping portion 71 is located and is fixedly connected to one end of the clamping portion 71. The clamping portion 71 is arranged parallel to the door frame 2. The clamping portion 71 is provided with a groove 73 that is recessed in a direction away from the door frame 2.
[0053] It should be noted that, in the direction perpendicular to the plane of the door frame 2, the hinge connecting seat 7 does not exceed any edge of the top plate 11 and the bottom plate 13, and the hinge connecting seat 7 is completely embedded in the top plate 11 and the bottom plate 13. The hinge connecting seat 7 and the top plate 11 and the bottom plate 13 can also be connected by gluing or screwing to make the connection between the hinge connecting seat 7 and the top plate 11 and the bottom plate 13 more stable.
[0054] Reference Figure 4 、 Figure 5The top and bottom hinge 3 includes a fixed base 31, a connecting strip 32 and a hinge base 33 connected in sequence. The fixed base 31 and the hinge base 33 are arranged in parallel. The connecting strip 32 connects the fixed base 31 and the hinge base 33. The fixed base 31 is fixedly connected to the cabinet 1, and the door frame 2 is rotatably connected to the hinge base 33. The side of the fixed base 31 away from the hinge base 33 includes a protrusion 34 protruding from the fixed base 31. The side of the protrusion 34 away from the hinge base 33 is provided with at least one convex tooth 340. The convex tooth 340 includes a protrusion 340 extending in a direction from the top plate 11 to the bottom plate 13. The upper convex tooth 341 and the lower convex tooth 342 are arranged opposite each other, and the protrusion 34 is embedded in the groove 73 of the hinge connecting seat 7. The groove 73 includes an upper concave tooth group 711 and a lower concave tooth group 712 arranged opposite each other. The upper concave tooth group 711 includes 1-N concave teeth 710, and the lower concave tooth group 712 also includes 1-N concave teeth 710. When the upper convex tooth 341 is engaged with the i-th concave tooth 710 of the upper concave tooth group 711, the lower convex tooth 342 is engaged with the i-th concave tooth 710 of the lower concave tooth group 712, where 1≤i≤N and i and N are both positive integers.
[0055] It should be noted that large-sized aluminum frame doors are usually heavy, and all the weight falls on the lower hinge. The protrusion 34 is embedded in the groove 73, and the convex teeth on the protrusion 34 and the concave teeth in the hinge connecting seat 7 engage with each other, making the connection between the top and bottom hinges 3 and the hinge connecting seat 7 more stable, and can avoid the occurrence of tilting or skewing problems of the lower hinge; the protrusion 34 is embedded in the groove 73, and the fixed base 31 of the top and bottom hinges fits with the top plate 11 and the bottom plate 13 without any large gaps, which is more beautiful and safe.
[0056] Specifically, the convex teeth 340 include an upper convex tooth 341 and a lower convex tooth 342 arranged opposite to each other in the direction from the top plate 11 to the bottom plate 13. The protrusion 34 is embedded in the groove 73 of the hinge connecting seat 7. The groove 73 includes an upper concave tooth group 711 and a lower concave tooth group 712 arranged opposite to each other. The upper concave tooth group 711 includes 1-N concave teeth 710, and the lower concave tooth group 712 also includes 1-N concave teeth 710. When the upper convex tooth 341 is engaged with the i-th concave tooth 710 of the upper concave tooth group 711, the lower convex tooth 342 is engaged with the i-th concave tooth 710 of the lower concave tooth group 712, where 1≤i≤N and i and N are both positive integers.
[0057] For example, when both the upper concave tooth group 711 and the lower concave tooth group 712 include three concave teeth 710, when the upper convex tooth 341 is engaged with the first concave tooth of the upper concave tooth group 711, the lower convex tooth 342 is engaged with the first concave tooth 710 of the lower concave tooth group 712; when the upper convex tooth 341 is engaged with the second concave tooth 710 of the upper concave tooth group 711, the lower convex tooth 342 is engaged with the first concave tooth 710 of the lower concave tooth group 712. The second concave tooth of the tooth group 712 is engaged; when the upper convex tooth 341 is engaged with the second concave tooth 710 of the upper concave tooth group 711, the lower convex tooth 342 is engaged with the second concave tooth 710 of the lower concave tooth group 712; when the upper convex tooth 341 is engaged with the third concave tooth 710 of the upper concave tooth group 711, the lower convex tooth 342 is engaged with the third concave tooth 710 of the lower concave tooth group 712.
[0058] It can be understood that the upper concave tooth group 711 and the lower concave tooth group 712 both include a plurality of concave teeth 710, and the areas of the upper concave tooth group 711 and the lower concave tooth group 712 are larger than the areas of the upper convex teeth 341 and the lower convex teeth 342, that is, the upper convex teeth 341 are engaged with the concave teeth in the middle of the upper concave tooth group 711, and the lower convex teeth 342 are engaged with the concave teeth in the middle of the lower concave tooth group 712, leaving adjustment space for the upper convex teeth 341 and the lower convex teeth 342; during installation, the upper convex teeth 341 are engaged with the concave teeth 710 in the middle of the upper concave tooth group 711, and the lower convex teeth 342 are engaged with the concave teeth 710 in the middle of the lower concave tooth group 712, then the upper convex teeth 341 and the lower convex teeth 342 are engaged. The convex teeth 342 all have upward and downward adjustment space. For example, when the upper concave tooth group 711 includes 5 concave teeth 710 and the lower concave tooth group 712 includes 5 concave teeth 710, during installation, the upper convex tooth 341 is clamped with the third concave tooth 710 in the upper concave tooth group 711, and the lower convex tooth 342 is clamped with the third concave tooth 710 in the lower concave tooth group 712. If the spacing between each concave tooth 710 in the upper concave tooth group 711 and the lower concave tooth group 712 is 1 mm, then the upper convex teeth 341 and the lower convex teeth 342 both have an adjustment space of 2 mm upward or downward. There is no specific limitation on the number of concave teeth in the upper concave tooth group 711 and the lower concave tooth group 712. When the lower hinge 37 sinks and deviates due to the load, the engagement position of the convex teeth 340 in the upper hinge 30 and the concave teeth 710 in the hinge connecting seat 7 can be adjusted downward in time without adjusting the position of the hinge connecting seat 7 in the top plate 11 or reassembling the hinge connecting seat 7, thereby avoiding damage to the top plate 11 caused by repeated disassembly and assembly of the hinge connecting seat 7.
[0059] Reference Figure 4-Figure 6At least one through hole 35 is provided on the protrusion 34, and at least one connecting hole 713 is also provided on the clamping portion 71. The protrusion 34 is fixedly connected to the clamping portion 71 by passing a screw 38 through the through hole 35 and the connecting hole 713; a hollow area 36 is also provided on the fixed base 31, and the projection of the hollow area 36 along the direction from the hinge base 33 to the fixed base 31 at least partially overlaps with the protrusion 34.
[0060] Specifically, Figure 5 In the figure, only two through holes 35 are provided on the protrusion 34 for schematic illustration, and the number and shape of the through holes are not specifically limited. Figure 4 Only four connection holes 713 are provided for schematic illustration. The number and shape of the connection holes are not specifically limited. A plurality of connection holes are provided to facilitate the adjustment of the perforation position of the screw 38 when there is an error between the top and bottom hinge 3 and the hinge connection seat 7 during installation; Figure 1 When the door panel 2 is closed, the door frame 2 is embedded in the top and bottom hinge 3. When the protrusion 34 is connected to the top plate 11 and the bottom plate 13 by screws 38, the screws 38 are placed in the hollow area 36, and the vertical hinge frame 22 will not collide with the screws 38, thereby preventing the screws 38 from scratching the vertical hinge frame 22.

The convex teeth 340 of the top and bottom hinge 3 can be engaged with any concave teeth 710 in the hinge connecting seat 7, so that the position of the top and bottom hinge 3 can be adjusted; the top and bottom hinge 3 and the hinge connecting seat 7 are locked by screws 38, and the convex teeth 340 of the top and bottom hinge 3 are engaged with the concave teeth 710 in the hinge connecting seat 7 to avoid position displacement, so that the door frame 2 and the cabinet body 1 are fixed more firmly.
[0062] In some optional embodiments, referring to Figure 4 、 Figure 5 The through hole 35 is located between the upper convex tooth 341 and the lower convex tooth 342 , and the connecting hole 713 is located between the upper concave tooth group 711 and the lower concave tooth group 712 .
[0063] Specifically, the through hole 35 is located on the axis of the fixed base 31, and the connecting hole 713 is located on the axis of the clamping portion 71. Figure 5 In the figure, only two through holes 35 are provided for schematic illustration. Figure 4 Only four connection holes 713 are provided for schematic illustration, and a plurality of connection holes 713 are provided to facilitate connection with different connection holes 713 when the hinge is adjusted left and right;
[0064] It can be understood that, compared with the through hole 35 only being provided at the upper or lower end of the fixed base 31 and the connecting hole 713 only being provided at the upper or lower end of the clamping portion 71, the through hole 35 is located between the upper convex tooth 341 and the lower convex tooth 342, and the connecting hole 713 is located between the upper concave tooth group 711 and the lower concave tooth group 712, that is, the through hole 35 is provided at the center of the fixed base 31, and the connecting hole 713 is only provided at the center of the clamping portion 71. The screw 38 passes through the through hole 35 and the connecting hole 713 to make the fixed base 31 and the clamping portion 71 more firmly connected even if the top and bottom hinges 3 are connected to the hinge connecting base 7.
[0065] In some optional embodiments, referring to Figure 4 、 Figure 7 , along the direction away from the door frame 2, the top plate 11 and the bottom plate 13 are provided with a connecting groove 111 recessed into the inside of the top plate 11 and the bottom plate 13, the hinge connecting seat 7 is embedded in the connecting groove 111, and the side of the connecting groove 111 close to the limiting portion 72 is provided with at least one limiting blind hole 112, and along the direction perpendicular to the plane where the limiting portion 72 is located, the side of the limiting portion 72 close to the limiting blind hole 112 is provided with a limiting column 721 protruding from the limiting portion 72, and the limiting column 721 is inserted into the limiting blind hole 112 to limit the hinge connecting seat 7.
[0066] It can be understood that a limiting column 721 is provided on the limiting portion 72 of the hinge connecting seat 7, and a corresponding limiting blind hole 112 is provided on the connecting groove 111 of the top plate 11 and the bottom plate 13. The limiting column 721 is inserted into the limiting blind hole 112 to limit the hinge connecting seat 7, thereby further improving the connection stability between the hinge connecting seat 7 and the top plate 11 and the bottom plate 13. Figure 4 Only two limiting posts 721 are provided for schematic illustration.
[0067] In some optional embodiments, referring to Figure 1 、 Figure 2 、 Figures 6-10The door frame 2 includes an upper horizontal frame 21, a hinge vertical frame 22, a lower horizontal frame 23 and a handle vertical frame 24 connected in sequence; in a direction perpendicular to the plane of the door frame 2, the hinge vertical frame 22 is further provided with a trimming strip 25 protruding from the hinge vertical frame 22; along the extension direction of the trimming strip 25, the length of the trimming strip 25 is less than the length of the hinge vertical frame 22, and both ends of the trimming strip 25 are provided with a cylindrical groove 251 recessed into the interior of the trimming strip 25, and the hinge base 33 is also provided with a mounting groove 331 corresponding to the cylindrical groove 251, and the trimming strip 25 is rotatably connected to the hinge base 33 by inserting the pin 4 into the cylindrical grooves 251 at both ends of the trimming strip 25 and the mounting groove 331 on the hinge base 33;
[0068] When the cabinet is in the closed state, the upper horizontal frame 21 is in contact with the top plate 11, and the lower horizontal frame 23 is in contact with the bottom plate 13; when the cabinet is in the open state, the top and bottom hinges 3 are fixed to the hinge connecting seats 7 on the top plate 11 and the bottom plate 13, and the door frame 2 rotates around the central axis of the pin 4. The maximum angle between the upper horizontal frame 21 and the top plate 11 is greater than 180 degrees, and the maximum angle between the lower horizontal frame 23 and the bottom plate 13 is greater than 180 degrees.
[0069] It should be noted that the end of the edge strip 25 close to the top plate 11 is the top end, and the end of the edge strip 25 close to the bottom plate 13 is the bottom end; Figure 4 Only the cylindrical groove 251 at the top of the trim strip 25 is shown as an example. The cylindrical groove 251 at the top of the trim strip 25 is recessed into the trim strip 25 in the direction from the upper transverse frame 21 to the lower transverse frame 23. Similarly, the cylindrical groove 251 at the bottom of the trim strip 25 is recessed into the trim strip 25 in the direction from the lower transverse frame 23 to the upper transverse frame 21.
[0070] It can be understood that along the extension direction of the edge strip 25, the length of the edge strip 25 is less than the length of the vertical hinge frame 22, and the sum of the length of the edge strip 25 and the length of the upper hinge 30 and the lower hinge 37 is equal to the length of the vertical hinge frame 22, which avoids the top and bottom hinges 3 from exceeding the edge of the door frame 2 after the top and bottom hinges 3 are set, saving materials and being more beautiful.
[0071] In the cabinet with a wide-angle opening and closing device provided in this embodiment, when closed, the upper horizontal frame 21 abuts against the top panel 11, and the lower horizontal frame 23 abuts against the bottom panel 13. When open, the top and bottom hinges 3 are fixed to the cabinet body, while the door frame 2 and the pin 4 rotate about the central axis of the pin 4. The maximum angle between the upper horizontal frame 21 and the top panel 11 is greater than 180 degrees, and the maximum angle between the lower horizontal frame 23 and the bottom panel 13 is greater than 180 degrees. During the opening process of the door frame 2, the top and bottom hinges 3 remain fixed to the cabinet body 1, while only the door frame 2 and the pin 4 rotate without any obstruction or restriction, thereby increasing the opening angle of the door frame 2. When open, the door frame 2 has no exposed hinges, resulting in a clean, simple, and safe design. The door frame 2 can remain open for extended periods without affecting the indoor activity space or the overall aesthetic requirements of the interior.
[0072] In some optional embodiments, referring to Figures 8-15 The pin 4 includes a fixing portion 41, a transition portion 42 and a separation ring 43 connecting the fixing portion 41 and the transition portion 42. The outer periphery of the fixing portion 41 is provided with a plurality of barbs 411 protruding from the pin 4. The fixing portion 41 is inserted into the cylindrical groove 251 and fixedly connected to the edge trimming strip 25. The transition portion 42 is inserted into the mounting groove 331 and rotatably connected to the hinge base 33, so that the edge trimming strip 25 is rotatably connected to the hinge base 33.
[0073] It should be noted that the fixing portion 41 of the pin 4 is inserted into the cylindrical groove 251 and fixedly connected to the edge strip 25, so that the door frame 2 and the pin 4 are connected to rotate as a whole; the outer periphery of the fixing portion 41 is provided with a plurality of barbs 411 protruding from the pin 4, which can further prevent the relative position of the edge strip 25 and the pin 4 from sliding; the adapter portion 42 of the pin 4 is inserted into the mounting groove 331 and is rotatably connected to the hinge base 33. Specifically, the outer periphery of the adapter portion 42 is smooth, and the friction between the adapter portion 42 and the hinge base 33 can be further reduced by oil lubrication or grease lubrication.
[0074] It can be understood that when the hinge is used to connect the door frame and the cabinet in the prior art, the hinge is fixed on the door frame. When the door frame is opened, the hinge rotates together with the door frame, resulting in a limited opening angle of the door frame. When the door frame 2 is rotated in this embodiment, the top and bottom hinges 3 are fixed to the top plate 11 and the bottom plate 13 and are stationary. What actually rotates are the door frame 2 and the pin 4. The door frame 2 and the pin 4 rotate together in the hinge base 33 with the central axis of the pin 4 as the axis. The door frame 2 rotates without any limit or obstruction, so the opening angle of the door frame 2 is increased. Figure 2 When the door frame 2 is fully opened, the opening angle of the door frame is approximately 260 degrees.
[0075] In some optional embodiments, referring to Figures 8-12The top and bottom hinge 3 includes an upper hinge 30, the mounting groove 331 of the upper hinge 30 passes through the hinge base 33, and a limiting groove 332 connected to the mounting groove 331 is provided on the top of the hinge base 33, and the inner diameter of the mounting groove 331 is smaller than the inner diameter of the limiting groove 332; the pin 4 includes an upper pin 44, and the outer periphery of the adapter portion 42 of the upper pin 44 is provided with a circle of card grooves 421 recessed into the interior of the pin, and a limiting retaining ring 5 is provided in the limiting groove 332 and the card groove 421 to limit the upper pin 44; the adapter portion 42 of the upper pin 44 is inserted into the mounting groove 331 and rotatably connected to the upper hinge 30, and the fixing portion 41 of the upper pin 44 is inserted into the cylindrical groove 251 at the top of the edge strip 25 and fixedly connected to the edge strip 25, so that the edge strip 25 is rotatably connected to the upper hinge 30.
[0076] It should be noted that in the current prior art, the upper hinge only serves as a limiter, and the weight of the door frame falls on the lower hinge. If the lower hinge is loose, the door frame and the upper pin are easily separated from the upper hinge, causing the door panel to fall, posing a safety hazard. In this embodiment, a limit groove 332 is further provided in the hinge base 33 of the upper hinge 30. The inner diameter of the limit groove 332 is larger than the inner diameter of the installation groove 331. For details, refer to Figure 11 The limiting groove 332 and the mounting groove 331 are connected in a T-shape. The limiting retaining ring 5 is locked in the limiting groove 332 and will not slide out of the mounting groove 331, thereby limiting the position of the upper pin 44. Specifically, along the extension direction of the upper pin 44, the length of the locking groove 421 is greater than the thickness of the limiting retaining ring 5, leaving space for the door panel to sink and prevent the upper pin 44 from directly rubbing against the limiting retaining ring 5. When the lower hinge 37 is seriously loose, the upper pin 44 sinks together with the door frame 2. At this time, the top of the upper pin 44 contacts and rubs against the limiting retaining ring 5, generating noise, prompting the user to report the problem in a timely manner.
[0077] It can be understood that in this embodiment, a limiting groove 332 is further provided in the hinge base 33 of the upper hinge 30, and the outer periphery of the pin 44 adapter 42 is provided with a circle of card grooves 421 recessed into the interior of the pin 4. By providing a limiting retaining ring 5 between the limiting groove 332 and the card groove 421, the upper pin 44 is limited, thereby avoiding the problem of the upper pin 44 falling off from the upper hinge 30 due to the loosening of the lower hinge 37.
[0078] In some optional embodiments, referring to Figure 8 、 Figure 9 、 Figure 13-15 The top and bottom hinge 3 also includes a lower hinge 37, and the pin 4 also includes a lower pin 45. The adapter portion 42 of the lower pin 45 is inserted into the mounting groove 331 of the lower hinge 37 and is rotatably connected to the lower hinge 37. The fixing portion 41 of the lower pin 45 is inserted into the cylindrical groove 251 at the bottom of the edge strip 25 and is fixedly connected to the edge strip 25, thereby rotatably connecting the edge strip 25 to the lower hinge 37.
[0079] It can be understood that the mounting groove 331 of the lower hinge 37 does not pass through the hinge base 33, and the adapter part 42 of the lower pin 45 is inserted into the mounting groove 331 of the lower hinge 37 and is rotatably connected to the lower hinge 37; the fixing part 41 of the lower pin 45 is inserted into the cylindrical groove 251 at the bottom of the trim strip 25 and is connected to the trim strip 25 as a whole. When the door frame rotates, the adapter part 42 rotates in the mounting groove 331, and the adapter part 42 and the mounting groove 331 can be further reduced in friction through oil lubrication or grease lubrication.
[0080] In some optional embodiments, continue to refer to Figure 14 A steel ball 6 is further provided between the mounting groove 331 of the lower hinge 37 and the lower pin 45 .
[0081] It should be noted that in the existing technology, the adapter part of the lower pin falls directly into the installation groove of the lower hinge, and the separation ring on the pin contacts the top of the lower hinge to limit the pin. When the door frame is rotated, the friction between the separation ring and the lower hinge will produce a harsh friction sound. After long-term friction, burrs will be generated, causing the door panel to rotate unsmoothly.
[0082] It is understood that in this embodiment, a steel ball 6 is provided between the mounting groove 331 of the hinge 37 and the lower pin 45. The lower pin 45 rests on the steel ball 6, eliminating the need for a spacer ring 43 to limit the lower pin 45. The steel ball 6 is highly hard and smooth. After a suitable amount of solid lubricant is injected into the mounting groove 331, the rotational friction between the lower pin 45 and the steel ball 6 produces virtually no friction noise. Specifically, the end of the adapter portion 42 of the lower pin 45, facing away from the fixed portion 41, is curved, i.e., the side of the adapter portion 42 that contacts the steel ball 6 is curved, allowing the lower pin 45 to fit snugly with the steel ball, resulting in smoother rotation.
[0083] In some optional embodiments, continue to refer to Figure 9 In a direction perpendicular to the plane where the door frame 2 is located, the handle vertical frame 24 is provided with an L-shaped handle strip 26 protruding from the handle vertical frame 24.
[0084] It is understood that the handle frame 24 is provided with an L-shaped handle strip 26 protruding from the handle frame 24, so that the handle frame 24 has a built-in handle groove. When a cabinet is equipped with a handle, the thickness of the handle is greater than the thickness of the edge strip 25. When multiple cabinets are arranged side by side and the door frames are opened 180 degrees, the additional handle will collide with the core board of the adjacent cabinet. The built-in handle groove of the handle frame 24 does not require a separate handle, which prevents collision with the core board and the glass core board from breaking.
[0085] In some optional embodiments, continue to refer to Figure 6 A gasket 39 is provided between the screw 38 and the protrusion 34 .
[0086] Specifically, Figure 6In this example, the area of gasket 39 is equal to the area of hollowed-out area 37. Gasket 39 can also be provided only at the position of screw 38 so that the area of gasket 39 and screw 38 are equal. It should be noted that gasket 39 can be a flat gasket to increase the contact area between screw 38 and protrusion 34 to tighten the connection; gasket 39 can also be an elastic gasket to reduce friction between screw 38 and protrusion 34 and prevent loosening.
[0087] It can be seen from the above embodiments that the cabinet with an adjustable connecting seat provided by the present invention achieves at least the following beneficial effects:
[0088] The present invention provides a cabinet with an adjustable connecting seat, comprising a cabinet body, a door frame and a top and bottom hinge connecting the cabinet body and the door frame; the cabinet body comprises a top panel, a left panel, a bottom panel and a right panel connected in sequence; a hinge connecting seat is provided on the side of the top panel and the bottom panel close to the door frame, the hinge connecting seat is embedded in the top panel and the bottom panel, and the top and bottom hinges are fixedly connected to the hinge connecting seat; the top and bottom hinges comprise a fixed base, a connecting strip and a hinge base connected in sequence, the side of the fixed base away from the hinge base comprises a protrusion protruding from the fixed base, the side of the protrusion away from the hinge base is provided with at least one convex tooth, the hinge connecting seat comprises a clamping portion and a limiting portion, a plurality of concave teeth are provided in the groove of the clamping portion, the convex teeth are clamped with at least some of the concave teeth; at least one through hole is also provided on the protrusion of the top and bottom hinge, and at least one connecting hole is also provided on the clamping portion, and the protrusion is fixedly connected to the clamping portion by passing a screw through the through hole and the connecting hole. The convex teeth of the top and bottom hinges can engage with any concave teeth in the hinge connecting groove, making the position of the top and bottom hinges adjustable; the top and bottom hinges and the hinge connecting grooves are locked by screws, and the convex teeth of the top and bottom hinges engage with the concave teeth in the hinge connecting grooves to avoid position displacement, making the fixation of the door frame and the cabinet body more stable.
