Detailed Implementation

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] In related technologies, existing doors are generally connected to the door frame via hinges. Due to potential installation errors in the hinges, the gap between the door and the door frame can become excessive, affecting the normal use of the door. A hinge typically consists of a first hinge assembly and a second hinge assembly. The first hinge assembly connects to the door frame, and the second hinge assembly includes a connecting seat and a connecting lug connected to the connecting seat. The connecting lug connects to the door, and the connecting seat is hinged to the first hinge assembly. To adjust the gap between the door and the door frame, an adjusting bolt is usually installed between the connecting seat and the connecting lug. Users can adjust the gap by turning the adjusting bolt to change the installation angle of the door. However, when the existing door rotates, the weight of the door is transmitted to the connecting seat through the connecting lug, causing the connecting lug to tend to rotate relative to the connecting seat. The adjusting bolt needs to withstand shear force from the connecting lug, making it prone to breakage and affecting the lifespan of the hinge.

[0042] Reference Figures 1 to 5 According to a first aspect embodiment of the present invention, the hinge includes a first page assembly 100, a second page assembly 200, an adjusting bolt 300, and a limiting structure. The first page assembly 100 is used to connect with a door frame. The second page assembly 200 includes a connecting seat 210 and two connecting seats 210. The connecting seat 210 is hinged to the first page assembly 100. One of the two connecting ears 220 is located on one side of the axial direction of the hinge axis of the connecting seat 210, and the other is located on the other side of the axial direction of the hinge axis of the connecting seat 210. The adjusting bolt 300 is located between the connecting seat 210 and the corresponding connecting ear 220. The adjusting bolt 300 is used to move the connecting seat 210 along the axial direction of the adjusting bolt 300. The limiting structure is used to restrict the swing of the connecting ear 220 around the axis of the hinge axis of the connecting seat 210. Thus, by setting the limiting structure, the shear force on the adjusting bolt 300 can be reduced to avoid the adjusting bolt 300 breaking, thereby improving the service life of the hinge.

[0043] For example, the first hinge assembly 100 is connected to the door frame, and the connecting ear 220 is connected to the door body so that the door body can rotate. When it is necessary to adjust the relative position between the door frame and the door body, the connecting ear 220 and the connecting seat 210 can be unlocked by the locking member 400. Then, the user can turn the adjusting bolt 300 to make the connecting seat 210 move along the axial direction of the adjusting bolt 300, thereby adjusting the gap between the door frame and the door body to meet the preset requirements. When the door body rotates, the limiting structure can restrict the connecting ear 220 from swinging around the axis of the hinge shaft of the connecting seat 210, which can reduce the shear force on the adjusting bolt 300 to avoid the adjusting bolt 300 from breaking and improve the service life of the hinge.

[0044] Reference Figure 8 , Figure 9 In some embodiments of this utility model, the limiting structure includes a limiting groove 221 provided in the connecting ear 220 and a limiting protrusion 211 provided in the connecting seat 210. The limiting protrusion 211 is accommodated in the limiting groove 221 and abuts against the side wall of the limiting groove 221, which can improve the connection strength between the connecting ear 220 and the connecting seat 210, thereby improving the service life of the hinge.

[0045] For example, a limiting groove 221 is provided on the connecting block 223. Along the axial direction of the hinge axis of the connecting shaft, limiting protrusions 211 are provided on opposite sides of the connecting seat 210. The limiting protrusions 211 are accommodated in the corresponding limiting groove 221 and abut against the side wall of the corresponding limiting groove 221. This can limit the swing of the connecting ear 220 relative to the connecting seat 210, improve the connection strength between the connecting ear 220 and the connecting seat 210, and thus improve the service life of the hinge.

[0046] It should be noted that the positions of the limiting groove 221 and the limiting protrusion 211 can be interchanged. That is, the limiting groove 221 is located on the connecting seat 210, while the limiting protrusion 211 is located on the connecting ear 220. This is not a limitation.

[0047] As another implementation method, the limiting structure can also be a structure in which a waist-shaped hole and a limiting pin are matched, and no limitation is made here.

[0048] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the hinge also includes a locking member 400, which is used to lock the connecting seat 210 and the connecting ear 220. The locking member 400 can assist the adjusting bolt 300 in bearing the weight of the door body, so as to avoid excessive force on the adjusting bolt 300, thereby improving the service life of the hinge.

[0049] For example, when it is necessary to adjust the relative position between the door frame and the door body, the connecting ear 220 and the connecting seat 210 can be unlocked by locking member 400. Then, the user can turn the adjusting bolt 300 to make the connecting seat 210 move along the axial direction of the adjusting bolt 300, thereby adjusting the gap between the door frame and the door body to meet the preset requirements. After the door body is adjusted, the connecting ear 220 and the connecting seat 210 are locked by locking member 400. Locking member 400 can help the adjusting bolt 300 bear the weight of the door body to avoid excessive force on the adjusting bolt 300, thereby improving the service life of the hinge.

[0050] Reference Figure 4 In some embodiments of this utility model, the locking member 400 includes a head 410 and a first rod portion 420. The head 410 is disposed at one end of the first rod portion 420. The first rod portion 420 is threadedly connected to the connecting ear 220 and the connecting seat 210 respectively. The head 410 abuts against the connecting ear 220. The operation is simple, convenient and quick, and can easily lock or unlock the connecting ear 220 and the connecting seat 210.

[0051] It should be noted that the locking component 400 can also be an eccentric locking structure. The eccentric locking structure includes an eccentric component and a locking shaft. The locking shaft passes through the connecting ear 220 and the connecting seat 210. The eccentric component has an eccentric part, which is rotatably connected to the locking shaft. This will not be described in detail here.

[0052] Reference Figure 9 In some embodiments of this utility model, the connecting ear 220 includes a connecting plate 222 and a connecting block 223 disposed on the connecting plate 222. The connecting plate 222 and the connecting block 223 enclose a receiving groove 224. Along the axial direction of the hinge shaft of the connecting seat 210, connecting protrusions 212 are respectively provided on opposite sides of the connecting seat 210. The connecting protrusions 212 are disposed in the corresponding receiving grooves 224. The adjusting bolt 300 is sequentially inserted through the connecting plate 222, the connecting protrusion 212 and the connecting block 223. The adjusting bolt 300 is threadedly engaged with the connecting protrusion 212, which can hide the connection position between the connecting protrusion 212 and the adjusting bolt 300, so as to avoid the connection position between the adjusting bolt 300 and the connecting protrusion 212 being exposed to the outside, thereby improving the service life of the hinge.

[0053] Reference Figure 4 , Figure 5In some embodiments of this utility model, the adjusting bolt 300 includes a first abutting part 310, a second abutting part 320, and a second rod part 330. The first abutting part 310 is disposed at one end of the second rod part 330, and the second abutting part 320 is disposed at the other end of the second rod part 330. The second rod part 330 is provided with external threads and is threadedly engaged with the connecting seat 210. The first abutting part 310 abuts against the connecting plate 222, and the second abutting part 320 abuts against the connecting block 223, which facilitates the assembly of the adjusting bolt 300.

[0054] For example, the first abutment 310 is the nut of the adjusting bolt 300, and the end of the second rod 330 away from the first abutment 310 is riveted to form the second abutment 320 by a riveting device. The connecting ear 220 is clamped between the first abutment 310 and the second abutment 320, so that the adjusting bolt 300 cannot move relative to the connecting ear 220. The operation is simple, convenient and quick, and it is easy to assemble the adjusting bolt 300.

[0055] As another implementation, a retaining ring can also be provided at the end of the second rod portion 330 away from the first abutment portion 310. The retaining ring abuts against the connecting block 223 and can also restrict the adjustment bolt 300 from moving along its axial direction. This is not a limitation here.

[0056] In some embodiments of this utility model, the first abutting part 310, the second abutting part 320, and the second rod part 330 are an integral structure, which can improve the structural strength of the adjusting bolt 300 and thus improve the service life of the adjusting bolt 300.

[0057] Reference Figure 1 , Figure 6 and Figure 7 In some embodiments of this utility model, the hinge further includes a connecting component 500, and the connecting seat 210 is hinged to the first page body component 100 through the connecting component 500, so that the second page body component 200 can rotate relative to the first page body component 100 to facilitate the opening or closing of the hinge.

[0058] As people's aesthetic demands for home decoration become increasingly stringent, visual appeal is required for every detail, including the aesthetics of doors. Traditional doors are primarily flat-edge doors, with smooth edges and the door leaf inside the door frame. Due to the installation of hinges, there is a gap of more than 3 millimeters between the flat-edge door and the door frame, inevitably resulting in poor sound insulation and airtightness. To meet the stringent requirements for sound insulation, heat insulation, and airtightness of entrance doors and bedroom doors, T-shaped doors emerged. Named for their T-shaped edges, the protruding part of the door presses against the door frame, creating a very tight fit between the door and the frame, resulting in better sound insulation than flat-edge doors. However, because the hinges currently used in T-shaped doors rotate around a single axis, the gap between the T-shaped door and the door frame needs to be increased to ensure smooth opening and closing, causing the T-shaped door to still suffer from poor sound insulation and airtightness.

[0059] Reference Figure 1 , Figure 6 and Figure 7 In some embodiments of this utility model, the first page assembly 100 is provided with a first mounting groove 110, and the opposite sidewalls of the first mounting groove 110 are respectively provided with first sliding grooves 120. The connecting seat 210 is provided with a second mounting groove 213, and the opposite sidewalls of the second mounting groove 213 are respectively provided with second sliding grooves 214. The connecting assembly 500 includes a first connecting member 510 and a second connecting member 520. The middle position of the first connecting member 510 is hinged to the middle position of the second connecting member 520. One end of the first connecting member 510 is hinged to the first page assembly 100. The other two ends of the 0 are respectively inserted into the corresponding second slide groove 214. One end of the second connector 520 is hinged to the connector 210. The other two ends of the second connector 520 are respectively inserted into the corresponding first slide groove 120. When the hinge switches from the unfolded state to the closed state, the distance between one end of the second connector 520 and one end of the first connector 510 gradually increases, which can reduce the gap between the T-shaped door and the door frame.

[0060] For example, when the hinge is in the closed state, the distance between one end of the second connector 520 and one end of the first connector 510 is the smallest, and the distance between the other end of the second connector 520 and the other end of the first connector 510 is the largest. When the hinge switches from the closed state to the open state, the distance between one end of the second connector 520 and one end of the first connector 510 gradually increases, and the other end of the first connector 510 gradually approaches one end of the second connector 520. The other end of the second connector 520 gradually approaches one end of the first connector 510, and one end of the second connector 520 performs an eccentric rotational motion relative to one end of the first connector 510. This allows the edge of the T-shaped door near the door frame to move towards the direction of exiting the door frame first, and then rotate relative to the door frame when the T-shaped door is opened. This reduces the gap between the T-shaped door and the door frame and ensures that the T-shaped door does not interfere with the door frame, so that the T-shaped door can be opened smoothly.

[0061] Reference Figure 1 , Figure 2 The door according to the second aspect embodiment of the present invention includes the hinge of the first aspect embodiment of the present invention. By setting a limiting structure, the shear force on the adjusting bolt 300 can be reduced to avoid the adjusting bolt 300 breaking, thereby improving the service life of the hinge.

[0062] For example, the first hinge assembly 100 is connected to the door frame, and the connecting ear 220 is connected to the door body so that the door body can rotate. When it is necessary to adjust the relative position between the door frame and the door body, the connecting ear 220 and the connecting seat 210 can be unlocked by the locking member 400. Then, the user can turn the adjusting bolt 300 to make the connecting seat 210 move along the axial direction of the adjusting bolt 300, thereby adjusting the gap between the door frame and the door body to meet the preset requirements. When the door body rotates, the limiting structure can restrict the connecting ear 220 from swinging around the axis of the hinge shaft of the connecting seat 210, which can reduce the shear force on the adjusting bolt 300 to avoid the adjusting bolt 300 from breaking and improve the service life of the hinge.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
