Description

Technical Field

[0001] This utility model relates to the field of hinge structure technology, and in particular to an adjustable door hinge and an oven cabinet. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. In home appliances and kitchen appliances, common cabinet door hinges typically consist of two hinges and a pin. One hinge is fixed to the door leaf, and the other is fixed to the door frame, thus allowing the door leaf to rotate relative to the door frame. However, after the above hinge structure is installed, misalignment may occur between the door leaf and the door frame. If the gap between the door leaf and the door frame is too large, it will lead to poor sealing; conversely, if the gap is too small, it will cause movement interference between the door leaf and the door frame, affecting the use of the home appliance or kitchen appliance.

[0003] To address the aforementioned issues, related technologies provide adjustable door hinges. These hinges include a hinge, a hinge shaft, a first nut, and a second nut. The hinge shaft is located on one side of the hinge and is threadedly connected to the first and second nuts. A through hole is provided on the door frame to allow the hinge shaft to extend into it. During installation, the first nut is first fitted onto the hinge shaft. Then, the hinge shaft is extended into the through hole in the door frame, and the second nut is screwed onto the end of the hinge shaft extending into the door frame. Finally, tools are used to tighten the first and second nuts, pressing the first nut against the outer wall of the door frame and the second nut against the inner wall, thus fixing the hinge shaft to the door frame. When adjusting the gap between the door leaf and the door frame, tools are still needed to loosen the first and second nuts, then move the hinge shaft along the through hole to the corresponding position, and finally tighten the first and second nuts again. While these adjustable door hinges allow adjustment of the door leaf's position relative to the door frame, their complex structure and cumbersome installation and adjustment methods make them challenging to implement. Utility Model Content

[0004] The first technical problem solved by this utility model is to provide an adjustable door hinge that can adjust the gap between the door leaf and the door frame, and has a simpler structure, optimizes the installation and adjustment methods, and improves assembly and adjustment efficiency.

[0005] The second technical problem solved by this utility model is to provide an oven cabinet that can adjust the gap between the door and the cabinet opening, and has a simpler structure, optimized installation and adjustment methods, and improved assembly and adjustment efficiency.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] An adjustable door hinge includes:

[0008] Hinge assembly, including connecting posts;

[0009] A hinge base is disposed on one side of the hinge assembly and close to the connecting post. The hinge base has a through hole, and a screw sleeve is rotatably disposed in the through hole. A first limiting structure is provided on the inner wall of the through hole, and a second limiting structure is provided at one end of the screw sleeve. The first limiting structure and the second limiting structure are rotatably engaged, and the first limiting structure and the second limiting structure restrict the screw sleeve from moving axially along the through hole. The other end of the screw sleeve extends out of the first end of the through hole, and the connecting post extends into the second end of the through hole and is threadedly connected to the screw sleeve.

[0010] Compared with the prior art, the adjustable door hinge of this utility model has the following advantages: During installation, the hinge assembly can be installed on the door leaf, and the hinge base can be installed on the door frame. Then, the connecting post of the hinge assembly is inserted into the through hole of the hinge base and threadedly connected to the screw sleeve. Since the first and second limiting structures can restrict the axial movement of the screw sleeve along the through hole, rotating the screw sleeve can drive the connecting post to move along the through hole towards the hinge base until the connecting post is installed in place, thereby installing the hinge assembly. Similarly, when disassembling the hinge assembly, rotating the screw sleeve can drive the connecting post to move along the through hole away from the hinge base until the connecting post is disengaged from the screw sleeve, thereby disassembling the hinge assembly. At the same time, when it is necessary to adjust the relative position of the door leaf and the door frame, rotating the screw sleeve can drive the connecting post to move towards or away from the hinge base, thereby driving the door leaf to move towards or away from the door frame, so as to adjust the fit clearance between the door leaf and the door frame as needed.

[0011] Therefore, the adjustable door hinge provided by this utility model has the function of adjusting the gap between the door leaf and the door frame, has the advantage of simple structure, and simplifies the installation, disassembly and adjustment methods, thereby improving assembly efficiency and adjustment efficiency.

[0012] In one embodiment, the first limiting structure is a limiting annular groove, which is coaxially arranged with the through hole, and the second limiting structure is an annular flange, which extends into the limiting annular groove.

[0013] In one embodiment, the hinge base includes a first base and a second base. The first base has a through hole, and the second base has a stepped hole. The through hole and the stepped hole are correspondingly arranged and connected to form the through hole. The stepped hole includes a first inner hole and a second inner hole. The inner diameter of the first inner hole is larger than the inner diameter of the second inner hole. The first inner hole is close to the first base and forms the limiting ring groove.

[0014] In one embodiment, the inner diameter of the through hole matches the outer diameter of the connecting post, and the inner diameter of the second inner hole is larger than the inner diameter of the through hole.

[0015] In one embodiment, the first seat and the second seat are connected by fasteners.

[0016] In one embodiment, the outer wall of the other end of the screw sleeve is provided with knurling.

[0017] In one embodiment, a drive groove is provided on the end face of the other end of the screw sleeve.

[0018] In one embodiment, the hinge assembly further includes:

[0019] hinge;

[0020] Pin;

[0021] A hinge bushing, wherein the hinge is hinged to the hinge bushing via the pin, and the connecting post is connected to the side wall of the hinge bushing, and the extending direction of the connecting post is perpendicular to the length direction of the pin.

[0022] The second technical problem mentioned above is solved by the following technical solution:

[0023] An oven cabinet, comprising:

[0024] The aforementioned adjustable door hinge;

[0025] The cabinet includes an opening and a mounting frame located near the opening. The hinge base is mounted on the mounting frame. The side wall of the cabinet has a mounting hole that aligns with the through hole. The connecting post extends into the mounting hole and the through hole and is threadedly connected to the screw sleeve.

[0026] The door leaf has the hinge assembly installed on one side.

[0027] Compared with the prior art, the oven cabinet of this utility model has the following advantages: During installation, the hinge assembly can be installed on the door leaf, and the hinge base can be installed on the mounting frame, aligning the through hole of the hinge base with the mounting hole. Then, the connecting post of the hinge assembly is sequentially inserted into the mounting hole and the through hole and threadedly connected to the screw sleeve. Since the first and second limiting structures can restrict the axial movement of the screw sleeve along the through hole, rotating the screw sleeve can drive the connecting post to move along the through hole towards the hinge base until the connecting post is installed in place, thereby installing the hinge assembly in place, and thus installing the door leaf on the cabinet. The door leaf rotates relative to the cabinet through the hinge assembly. Similarly, when disassembling the door leaf, rotating the screw sleeve can drive the connecting post to move along the through hole away from the hinge base until the connecting post disengages from the screw sleeve, thereby removing the hinge assembly and the door leaf from the cabinet. Meanwhile, when it is necessary to adjust the relative position of the door leaf and the cabinet opening, the connecting column can be moved closer to or further away from the hinge base by rotating the screw sleeve, thereby moving the door leaf closer to or further away from the opening, so as to adjust the fitting gap between the door leaf and the opening as needed.

[0028] Therefore, the door of the oven cabinet provided by this utility model can be installed on the cabinet body by adjustable door hinges. The adjustable door hinges have the function of adjusting the gap between the door and the opening, and have the advantages of simple structure. At the same time, they simplify the installation, disassembly and adjustment methods, and improve the assembly efficiency and adjustment efficiency.

[0029] In one embodiment, the opening is located on the front side of the cabinet, and the mounting frame includes a connecting plate and a mounting plate. The outer surface of the mounting plate is parallel to the left and right side walls of the cabinet. One end of the connecting plate is connected to the mounting plate, and the other end extends toward the hinge assembly. A notch is provided on the side of the mounting plate opposite to the connecting plate. The notch is aligned with the mounting hole. The hinge base is mounted on the mounting plate by fasteners.

[0058] This utility model provides an adjustable door hinge and an oven cabinet, which will be described below in conjunction with... Figures 1 to 12 The embodiments of this utility model are described in detail.

[0059] See Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of the adjustable door hinge of this embodiment is shown. Figure 2 The front view of the adjustable door hinge of this embodiment is shown. Figure 3 A cross-sectional structural schematic diagram of the adjustable door hinge of this embodiment is shown. According to an embodiment of the present invention, in a first aspect, an adjustable door hinge is provided, comprising: a hinge assembly 1 and a hinge base 2.

[0060] Hinge assembly 1 includes a connecting post 1031;

[0061] The hinge base 2 is located on one side of the hinge assembly 1 and is positioned close to the connecting post 1031. The hinge base 2 has a through hole 201, and a screw sleeve 3 is rotatably disposed inside the through hole 201. A first limiting structure is provided on the inner wall of the through hole 201, and a second limiting structure is provided at one end of the screw sleeve 3. The first limiting structure and the second limiting structure are rotatably engaged, and the first limiting structure and the second limiting structure restrict the screw sleeve 3 from moving axially along the through hole 201. The other end of the screw sleeve 3 extends out of the first end of the through hole 201, and the connecting post 1031 extends into the second end of the through hole 201 and is threadedly connected to the screw sleeve 3.

[0062] During installation, the hinge assembly 1 can be installed on the door leaf, and the hinge base 2 can be installed on the door frame. Then, the connecting post 1031 of the hinge assembly 1 is inserted into the through hole 201 of the hinge base 2 and threadedly connected to the screw sleeve 3. Since the first limiting structure and the second limiting structure can restrict the axial movement of the screw sleeve 3 along the through hole 201, rotating the screw sleeve 3 can drive the connecting post 1031 to move along the through hole 201 towards the hinge base until the connecting post 1031 is installed in place, thereby installing the hinge assembly 1 in place. Similarly, when disassembling the hinge assembly 1, rotating the screw sleeve 3 can drive the connecting post 1031 to move along the through hole 201 away from the hinge base until the connecting post 1031 is disengaged from the screw sleeve 3, thereby disassembling the hinge assembly 1. Meanwhile, when it is necessary to adjust the relative position of the door leaf and the door frame, the connecting column 1031 can be moved closer to or further away from the hinge base by rotating the screw sleeve 3, thereby moving the door leaf closer to or further away from the door frame, so as to adjust the fit gap between the door leaf and the door frame as needed.

[0063] Therefore, the adjustable door hinge provided by this utility model has the function of adjusting the gap between the door leaf and the door frame, and has the advantages of simple structure. At the same time, it simplifies the installation, disassembly and adjustment methods, and improves the assembly efficiency and adjustment efficiency. In addition, the screw sleeve 3 has an axial limiting effect on the connecting post 1031, and the through hole 201 has a radial limiting effect on the connecting post 1031, which can prevent the connecting post 1031 from shaking relative to the hinge base 2.

[0064] See Figure 3 and Figure 4 , Figure 4 A schematic diagram of the hinge base of this embodiment is shown. In one embodiment, the first limiting structure is a limiting annular groove 202, which is coaxially arranged with the through hole 201, and the second limiting structure is an annular flange 301, which extends into the limiting annular groove 202.

[0065] In the axial direction of the through hole 201, the surfaces of the annular flange 301 and the limiting annular groove 202 abut and rotate, allowing the annular flange 301 to rotate only around the central axis of the through hole 201 relative to the limiting annular groove 202, and preventing it from moving relative to the limiting annular groove 202 in the axial direction of the through hole 201. This restricts the axial movement of the screwing sleeve 3 along the through hole 201, enabling the connecting column 1031 to move closer to or away from the hinge base 2 simply by rotating the screwing sleeve 3, simplifying the installation, disassembly, and adjustment methods. As an alternative implementation, the limiting annular groove can also be provided on the outer wall of the screwing sleeve 3, and the annular flange can also be provided on the inner wall of the through hole 201, providing the same limiting effect for the screwing sleeve 3.

[0066] See Figure 4 and Figure 6 In one embodiment, the connecting post 1031 is provided with an external thread 10311 on the outer wall of the end opposite to the hinge assembly 1, and the end of the screw sleeve 3 located in the through hole 201 is provided with a threaded hole 304, which is coaxial with the through hole 201.

[0067] See Figure 4 and Figure 5 , Figure 5 A schematic diagram of the through hole structure of this embodiment is shown. In one embodiment, the hinge base 2 includes a first base 203 and a second base 204. The first base 203 is provided with a through hole 2031, and the second base 204 is provided with a stepped hole 2041. The through hole 2031 and the stepped hole 2041 are correspondingly provided. The through hole 2031 and the stepped hole 2041 are connected to form a through hole 201. The stepped hole 2041 includes a first inner hole and a second inner hole. The inner diameter of the first inner hole is larger than the inner diameter of the second inner hole. The first inner hole is close to the first base 203 and forms a limiting annular groove 202.

[0068] When assembling the hinge base 2, the end of the screw sleeve 3 facing away from the annular flange 301 can be inserted into the first inner hole and the second inner hole. After the screw sleeve 3 is inserted into place, the annular flange 301 abuts against the first inner hole, and the end of the screw sleeve 3 facing away from the annular flange 301 extends out from the second inner hole. Then, while keeping the central axis of the through hole 2031 of the first base 203 aligned with the central axis of the stepped hole 2041, the first base 203 and the second base 204 are spliced ​​together. The part of the surface of the first base 203 facing the second base 204 abuts against the annular flange 301, thereby forming a limiting annular groove 202. The hinge base 2 has a simple structure and simple processing method. The limiting annular groove 202 formed by the stepped hole 2041 and the surface of the first base 203 further simplifies the processing method.

[0069] See Figure 5 In one embodiment, the inner diameter of the through hole 2031 matches the outer diameter of the connecting post 1031, and the inner diameter of the second inner hole is larger than that of the through hole 2031. This configuration allows the through hole 2031 to guide the connecting post 1031, eliminating the need for other guiding structures to direct the movement of the connecting post 1031. It also prevents the connecting post 1031 from wobbling relative to the hinge base 2, thereby preventing the door leaf from wobbling relative to the door frame. The size of the second inner hole prevents movement interference between the outer wall of the screw sleeve 3 and the second inner hole.

[0070] See Figure 5 In one embodiment, the first base 203 and the second base 204 are connected by fasteners. This facilitates the assembly and disassembly of the hinge base 2.

[0071] See Figure 5 and Figure 6 In one embodiment, the first base 203 is provided with a first connecting hole 2032 and a second connecting hole 2033, which are located on both sides of the through hole 2031. The second base 204 is provided with a third connecting hole 2042 and a fourth connecting hole 2043, which are aligned with the first connecting hole 2032 and the fourth connecting hole 2043. The hinge base 2 includes a first fastening bolt 205 and a second fastening bolt 206. The first fastening bolt 205 passes through the third connecting hole 2042 and is threadedly connected to the first connecting hole 2032. The second fastening bolt 206 passes through the fourth connecting hole 2043 and is threadedly connected to the second connecting hole 2033. After the first fastening bolt 205 and the second fastening bolt 206 are tightened into place, the first fastening bolt 205 and the second fastening bolt 206 can firmly fix the first seat 203 and the second seat 204. During subsequent disassembly, the first fastening bolt 205 and the second fastening bolt 206 can be removed to separate the first seat 203 and the second seat 204.

[0072] See Figure 5 In one embodiment, the first connecting hole 2032 and the second connecting hole 2033 are threaded holes, and the third connecting hole 2042 and the fourth connecting hole 2043 are through holes with smooth inner walls. During installation, the first fastening bolt 205 extends into the third connecting hole 2042 and is threadedly connected to the first connecting hole 2032, and the second fastening bolt 206 extends into the fourth connecting hole 2043 and is threadedly connected to the second connecting hole 2033. After the first fastening bolt 205 and the second fastening bolt 206 are tightened into place, the heads of the first fastening bolt 205 and the heads of the second fastening bolt 206 press the second seat 204 onto the first seat 203, thereby simplifying the processing method of the third connecting hole 2042 and the fourth connecting hole 2043.

[0073] See Figure 1 In one embodiment, the outer wall of the other end of the screw sleeve 3 is provided with knurling 302. Knurling 302 can increase friction, and installation can be completed by manually screwing on the knurling 302, which simplifies the installation method.

[0074] See Figure 1 In one embodiment, a driving groove 303 is provided on the end face of the other end of the screw sleeve 3. The other end of the screw sleeve 3 is a closed plane, and the driving groove 303 is provided on the plane. The driving groove 303 can be a cross groove, a slotted groove, or an inner corner groove, etc., which means that it can be installed with the corresponding screwdriver, simplifying the installation method.

[0075] See Figure 3 and Figure 6In one embodiment, the hinge assembly 1 further includes a hinge 101, a pin 102, and a hinge bushing 103. The hinge 101 is hinged to the hinge bushing 103 via the pin 102, and a connecting post 1031 is connected to the side wall of the hinge bushing 103, with the extending direction of the connecting post 1031 perpendicular to the length direction of the pin 102.

[0076] When the position of the door leaf needs to be adjusted, the connecting post 1031 can be moved closer to or further away from the hinge base 2 by rotating the screw sleeve 3. This, in turn, moves the pin 102 closer to or further away from the hinge base 2, thereby adjusting the relative position between the door leaf and the door frame. The principle is that the relative position between the hinge base 2 and the door frame is fixed, the relative position between the hinge 101 and the door leaf is fixed, the hinge sleeve 103 and the hinge 101 are hinged together by the pin 102, and the relative position between the pin 102 and the door leaf is also fixed. The connecting post 1031 is connected to the side wall of the hinge sleeve 103. When the rotating screw sleeve 3 drives the connecting column 1031 to move axially along the through hole 201, the pin 102 also moves axially along the through hole 201 simultaneously, causing the door leaf to move axially along the through hole 201. The mating position of the end of the door leaf away from the pin 102 and the door frame also changes synchronously, thereby adjusting the relative position between the door leaf and the door frame as needed, so that there is a suitable mating clearance between the door leaf and the door frame, ensuring the sealing of the door leaf when closed, and avoiding interference between the door leaf and the door frame when the door leaf moves, thus avoiding affecting the use of home appliances or kitchen appliances. Moreover, the adjustment method is simple and easy to operate.

[0077] See Figure 3 In one embodiment, the hinge 101 is provided with a first bushing 1011 and a second bushing 1012. The shaft holes of the first bushing 1011 and the second bushing 1012 are coaxially arranged, and there is a gap between the first bushing 1011 and the second bushing 1012. The hinge bushing 103 is disposed between the first bushing 1011 and the second bushing 1012. The pin 102 passes through the first bushing 1011, the hinge bushing 103 and the second bushing 1012, thereby improving the connection stability.

[0078] See Figure 6 In one embodiment, the hinge 101 is provided with a first positioning hole 1013 and a second positioning hole 1014, which are spaced apart. Two third fastening bolts 104 pass through the first positioning hole 1013 and the second positioning hole 1014 respectively to fix the hinge 101 to the door leaf.

[0079] See Figure 3 and Figure 6The pin 102 includes a first pin 1021 and a second pin 1022. The first pin 1021 has a pin hole at one end opposite to its head. The first pin 1021 passes through a first bushing 1011, a hinge bushing 103, and a second bushing 1012. The second pin 1022 is fixed to the pin hole. The head of the first pin 1021 abuts against the first bushing 1011, and the head of the second pin abuts against the second bushing 1012.

[0080] See Figure 7 , Figure 8 , Figure 9 and Figure 10 According to an embodiment of the present invention, in a second aspect, an oven cabinet is also provided, comprising: the aforementioned adjustable door hinge, cabinet body 41, and door leaf 42.

[0081] The cabinet 41 includes an opening and a mounting frame 43 located near the opening. The hinge base 2 is mounted on the mounting frame 43. The side wall of the cabinet 41 has a mounting hole 411 that aligns with the through hole 201. The connecting post 1031 extends into the mounting hole 411 and the through hole 201 and is threadedly connected to the screw sleeve 3.

[0082] A hinge assembly 1 is installed on one side of the door leaf 42.

[0083] During installation, the hinge assembly 1 can be installed on the door leaf 42, and the hinge base 2 can be installed on the mounting frame 43, so that the through hole 201 of the hinge base 2 is aligned with the mounting hole 411. Then, the connecting post 1031 of the hinge assembly 1 is inserted into the mounting hole 411 and the through hole 201 in sequence and threadedly connected to the screw sleeve 3. Since the first limiting structure and the second limiting structure can restrict the axial movement of the screw sleeve 3 along the through hole 201, the connecting post 1031 can be driven to move along the through hole 201 towards the hinge base by rotating the screw sleeve 3 until the connecting post 1031 is installed in place, thereby installing the hinge assembly 1 in place, and thus installing the door leaf 42 on the cabinet 41. The door leaf 42 rotates relative to the cabinet 41 through the hinge assembly 1. Similarly, when disassembling the door leaf 42, rotating the screw sleeve 3 will move the connecting post 1031 along the through hole 201 away from the hinge base until the connecting post 1031 disengages from the screw sleeve 3, thereby removing the hinge assembly 1 and the door leaf 42 from the cabinet 41. Simultaneously, when it is necessary to adjust the relative position of the door leaf 42 and the opening of the cabinet 41, rotating the screw sleeve 3 will move the connecting post 1031 closer to or further away from the hinge base, thereby moving the door leaf 42 closer to or further away from the opening, thus adjusting the fit clearance between the door leaf 42 and the opening as needed.

[0084] Therefore, the door 42 of the oven cabinet provided by this utility model can be installed on the cabinet body 41 by an adjustable door hinge. The adjustable door hinge has the function of adjusting the gap between the door and the opening, and has the advantages of simple structure. At the same time, it simplifies the installation, disassembly and adjustment methods, and improves the assembly efficiency and adjustment efficiency.

[0085] It should be noted that, in addition to the oven cabinet of this embodiment, adjustable door hinges can be used in other household appliances and kitchen appliances with cabinet structures, achieving the same technical effect, and will not be exemplified here. Furthermore, adjustable door hinges are suitable not only for flat door panels but also for door panels with curved edges.

[0086] See Figure 7 In one embodiment, the cabinet 41 is fitted with two doors 42, which together close the opening. Each door 42 is mounted on the left and right sides of the cabinet 41 via two adjustable hinges, which are spaced apart vertically. In this embodiment, the adjustable hinges can be used to move the door 42 horizontally to adjust the clearance between the two doors in the left-right direction.

[0087] See Figure 8 , Figure 10 , Figure 11 and Figure 12 In one embodiment, the opening is located on the front side of the cabinet 41. The mounting frame 43 includes a connecting plate 431 and a mounting plate 432. The outer surface of the mounting plate 432 is parallel to the left and right side walls of the cabinet 41. One end of the connecting plate 431 is connected to the mounting plate 432, and the other end extends towards the hinge assembly 1. A notch 4321 is provided on the side of the mounting plate 432 opposite to the connecting plate 431. The notch 4321 is aligned with the mounting hole 411. The hinge base 2 is mounted on the mounting plate 432 by fasteners. When installing the hinge base 2, since the notch 4321 and the mounting hole 411 are aligned, the installation position of the screw sleeve 3 can be positioned through the notch 4321, thereby facilitating the alignment of the through hole 201 and the mounting hole 411.

[0088] See Figure 10 and Figure 12In one embodiment, the mounting plate 432 is provided with a first through hole 4322 and a second through hole 4323. In the vertical direction, the first through hole 4322 and the second through hole 4323 are located on opposite sides of the notch 4321. The first through hole 4322 is aligned with the first connecting hole 2032 and the third connecting hole 2042, and the second through hole 4323 is aligned with the second connecting hole 2033 and the fourth connecting hole 2043. A first fastening bolt 205 passes through the first through hole 4322 and the third connecting hole 2042 and is threadedly connected to the first connecting hole 2032. A second fastening bolt 206 passes through the second through hole 4323 and the fourth connecting hole 2043 and is threadedly connected to the second connecting hole 2033. Thus, the hinge base 2 can be fixed to the mounting plate 432 by the first fastening bolt 205 and the second fastening bolt 206, eliminating the need for other fastening structures and simplifying the structure.

[0089] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0090] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
