Description

Technical Field

[0001] The utility model belongs to the technical field of door leaf connecting hinges, and in particular relates to a novel two-dimensional invisible hinge. Background Art

[0002] A hinge is a connecting component that connects a door leaf to a door frame. After the door leaf is connected to the door frame by the hinge, the door leaf can rotate around the door frame, that is, the door leaf can be opened or closed.

[0003] When installing a rotating door leaf, hinges or other rotating hinges are indispensable components. Since hinges are a conventional connecting component, with the improvement of material living standards, people have higher and higher requirements for hinges, such as the aesthetics and reliability of hinges. Conventional hinge screws are often exposed, and the exposed screws are easily corroded or scratched on people's clothes, and their aesthetics and reliability are insufficient.

[0004] Based on this, the applicant Foshan Yueguoxuan Technology Co., Ltd. applied for a new type of invisible hinge on June 12, 2023. The new type of invisible hinge has screw hole areas at both ends of the door frame leaf, and a first hidden plate is provided on the screw hole area. The first hidden plate can cover and hide the first screw hole on the screw hole area, thereby improving the aesthetics and safety of the utility model.

[0005] Therefore, some problems existing in the prior art can be solved.

[0006] Subsequently, the applicant, Foshan Yueguoxuan Technology Co., Ltd., discovered during the implementation of the new invisible hinge that the new invisible hinge had the following problems: the new invisible hinge had at least the following problem: when the door frame leaves and door leaf leaves of the new invisible hinge were installed on the door frame and door leaf, since the position between the door frame leaves and the door leaf leaves was completely fixed and could not be adjusted, the distance between the door frame and the door leaf was also fixed and could not be adjusted, and could not meet different requirements.

[0007] Based on this, the applicant, Foshan Yueguoxuan Technology Co., Ltd., applied for an improved hinge on January 25, 2024. During use, Foshan Yueguoxuan Technology Co., Ltd. found that the hinge applied for on January 25, 2024 still had the following problems:

[0008] A positioning edge is formed on the side of the door leaf away from the door frame leaf. Although the positioning edge can play a positioning role, it has the following defects during use: the positioning edge is at the edge, so when the hinged door leaf is installed on the door leaf, a slender positioning groove will also be provided on the profile of the corresponding door leaf, or the positioning edge of the door leaf leaf will be flush with the edge of the profile of the door leaf. For the slender positioning groove, installation is not convenient because the positioning edge is difficult to insert into the positioning groove. When the positioning edge of the door leaf leaf is flush with the edge of the profile of the door leaf, the thickness of the profile will be limited, which is not conducive to use in different scenarios. And the existence of the positioning edge will affect the user experience to a certain extent.

[0009] Based on this, it is necessary to develop a new hinge to solve the technical problems of the hinge applied for on January 25, 2024. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] Figure 1 to Figure 6 The structure of a novel two-dimensional invisible hinge in one embodiment of the utility model is schematically shown.

[0033] like Figure 1 to Figure 6 As shown, a novel two-dimensional invisible hinge comprises a door frame page 1 and a door leaf page 2.

[0034] The door frame page 1 and the door leaf page 2 can be rotatably connected. The upper and lower ends of the door frame page 1 can be formed with a first screw hole area 11, and the first screw hole is formed on the first screw hole area 11. A positioning protrusion 21 is provided on the back of the door leaf page 2. The positioning protrusion 21 can be inserted into the groove at the corresponding position of the door leaf, so that the positioning protrusion 21 plays a positioning role.

[0035] The positioning protrusion 21 is in a rectangular shape, and is located in the middle of the back of the door leaf 2. A positioning protrusion step 12 is provided on the back of the door frame leaf 1. Of course, the shape of the positioning protrusion 21 can be set according to actual conditions, such as: it can also be a square or other shapes, as long as the positioning protrusion 21 is provided on the back of the door leaf 2. In addition, the positioning protrusion step 12 can also play a positioning role.

[0036] An adjusting component 3 may be provided between the door frame page 1 and the door leaf page 2, and the position between the door frame page 1 and the door leaf page 2 may be adjusted by the adjusting component 3. Since the door frame page 1 is installed on the door frame, the corresponding door leaf page 2 may be installed on the door leaf, and therefore, the position between the door frame and the door leaf may be ultimately adjusted.

[0037] The novel two-dimensional invisible hinge of the present application is provided with an adjustment component 3 between the door frame page 1 and the door leaf page 2, and the adjustment component 3 can adjust the position between the door frame page 1 and the door leaf page 2, so as to finally adjust the position between the door frame and the door leaf. Specifically, the position mentioned here means that when the door frame page 1 and the door leaf page 2 are covered, the adjustment component 3 can adjust the distance between the door frame page 1 and the door leaf page 2. Of course, since the present invention itself is applied to the door frame and the door leaf, the adjustment distance is very small, and the adjustable distance is usually within 0.3 cm.

[0038] The specific structure of the adjustment component 3 of the utility model is described in detail below: In this embodiment, the adjustment component 3 includes a connecting screw 31 and an adjusting screw 32. The connecting screw 31 can ultimately connect the door frame page 1 and the door leaf page 2, and after rotating the connecting screw 31, the position between the door frame page 1 and the door leaf page 2 can be adjusted, and the adjusting screw 32 can play a positioning role, that is, the adjusting screw 32 can ultimately resist the door frame page 1 and the door leaf page 2.

[0039] In this embodiment, there are two connecting screws 31 and one adjusting screw 32. The adjusting component 3 also includes a connecting piece 33. One end of the two connecting screws 31 passes through the door leaf 2 and is connected to the connecting piece 33. Since there are two connecting screws 31 and one end of the connecting screw 31 is connected to the connecting piece 33, the two connecting screws 31 can be formed into a whole through the connecting piece 33 to prevent the connection screws 31 from rotating by themselves and affecting the use. At the same time, the connecting piece 33 can be supported by the adjusting screw 32 because the connecting piece 33 is connected to the door leaf 2. In other embodiments, the number of connecting screws 31 can be set according to actual use requirements, such as: the number of connecting screws 31 can also be four, and the number of adjusting screws 32 can be one.

[0040] Of course, if Figure 3 and Figure 4As shown, the utility model may further include a rotating part 4, which is rotatably connected to the door frame page 1, such as: a rotating shaft is fixedly installed on the door frame page 1, and the rotating part 4 can be rotatably connected to the rotating shaft, and the rotating part 4 is connected to the door leaf 2 through the adjusting component 3. The rotating part 4 is set in a long strip shape, and after rotating a certain angle, it can cover one side of the door frame page 1. Specifically, one end of the connecting screw 31 passes through the rotating part 4 and the positioning protrusion 21 of the door leaf 2 in sequence and is connected to the connecting piece 33. At the same time, the adjusting screw 32 can correspondingly abut the door leaf 2. The rotating part 4 is connected to the door frame page 1 through the rotating shaft, and the adjusting component 3 connects the rotating part 4 and the door leaf 2.

[0041] In addition, due to the limitation of the door frame leaf 1 and the door leaf 2, the rotation angle between the door frame leaf 1 and the door leaf 2 is often limited to between 0 and 110 degrees.

[0042] The specific structure of the rotating part 4 and the door leaf 2 of the utility model is described in detail below:

[0043] Specifically, the adjusting component 3 includes two connecting screws 31, an adjusting screw 32 and a connecting piece 33. One end of the two connecting screws 31 passes through the rotating part 4 and the door leaf 2 in turn, and then one end of the connecting screw 31 is connected to the connecting piece 33 on the back side of the positioning protrusion 21 of the door leaf 2. Since one end of the two connecting screws 31 is connected to the connecting piece 33, the two connecting screws 31 will not rotate by themselves. At the same time, one end of an adjusting screw 32 passes through the rotating part 4 and rests on the door leaf 2. At this time, the adjusting screw 32 can play a positioning role, so that the connection between the rotating part 4 and the door leaf 2 is tighter and fitter.

[0044] Next, when the position between the rotating part 4 and the door leaf 2 needs to be adjusted, for example, when the position distance between the rotating part 4 and the door leaf 2 becomes smaller, the adjusting screw 32 is rotated by a certain angle so that the adjusting screw 32 does not abut against the door leaf 2. At the same time, the two connecting screws 31 are rotated. Finally, after the rotating part 4 and the door leaf 2 reach the specified position, the adjusting screw 32 is rotated again so that the adjusting screw 32 abuts against the door leaf 2 to complete the adjustment.

[0045] In this embodiment, the upper and lower ends of the door frame page 1 are integrally formed with a second screw hole area 22, the second screw hole area 22 is inclined, a second screw hole is formed on the second screw hole area 22, and the corresponding second screw hole is also inclined. A second decorative panel 6 can be installed on the second screw hole area 22. When the second decorative panel 6 is covered on the second screw hole, the upper end surface of the second decorative panel 6 is flush with the upper end surface of the door leaf 2.

[0046] In the present invention, since an adjustment component 3 is provided between the door frame page 1 and the door leaf page 2, the adjustment component 3 can adjust the position between the door frame page 1 and the door leaf page 2, and finally adjust the position between the door frame and the door leaf. The position between the door frame and the door leaf can be slightly adjusted according to the actual situation, and the position here usually refers to the distance, so that the door frame and the door leaf can be used better together, and the problem of abnormal noise during the door opening and closing process caused by the falling of the door leaf and the scratching of the door frame profile and the door leaf profile can be solved by two-dimensional adjustment of the new two-dimensional invisible hinge.

[0047] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
