Description

Technical Field

[0001] This utility model belongs to the field of building materials technology, and specifically relates to a door hinge structure. Background Technology

[0002] Interior doors are one of the most common facilities in home decoration and building materials. Existing interior doors mainly use multiple hinges to rotate and connect with the door frame to realize the opening and closing of the door. They are the most common due to their simple structure and convenient construction and installation. However, this structure has many shortcomings.

[0003] First, existing interior doors have excessively large gaps when opened due to hinge structure issues, posing a significant danger to families with children. Second, the multiple hinges are distributed vertically and experience uneven stress, making them prone to damage.

[0004] Therefore, a new type of door hinge structure is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a door hinge structure with small door gaps, uniform force distribution, and less susceptibility to damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A door hinge structure, characterized in that it includes an upper hinge and a lower hinge respectively disposed at the top and bottom of the door panel;

[0008] The upper rotating shaft includes an upper fixing block, a limiting block, and an upper connecting member. The upper connecting member is fixedly connected to the top and side ends of the door panel, and a rotating shaft is provided on the top of the upper connecting member. A rotating groove corresponding to the rotating shaft is opened on one side of the upper fixing block. The upper fixing block and the upper connecting member are rotatably connected through the rotating shaft and the rotating groove. One end of the limiting block is opened with a shaft hole corresponding to the rotating shaft and is sleeved on the rotating shaft through the shaft hole. The other end of the limiting block is fixedly connected to the upper fixing block.

[0009] The lower rotating shaft includes a lower connector, a lower fixing block, a ball, and a rotating seat. The lower connector is fixedly connected to the bottom and side ends of the door panel. The ball is rotatably connected between the lower connector and the rotating seat. The bottom of the rotating seat is fixedly connected to the lower fixing block.

[0010] Furthermore, the lower connector and the upper connector are provided with reinforcing ribs.

[0011] Furthermore, the top of the lower connector and the top of the rotating seat are provided with concave spherical grooves corresponding to the sphere.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Smaller door gaps improve security.

[0014] Traditional hinged door hinges have structural limitations, resulting in a large gap when the door is opened, which poses a safety hazard such as pinching injuries to families with children.

[0015] This structure, through the combination of "rotating shaft + rotating groove" on the upper rotating shaft and "sphere + concave ball groove" on the lower rotating shaft, reduces the offset space when the door panel rotates, significantly reduces the door gap, and lowers safety risks.

[0016] 2. Distributes stress evenly and is not easily damaged.

[0017] Traditional hinges require multiple vertically distributed hinges, which can easily lead to localized wear or damage due to uneven stress.

[0018] This structure uses upper and lower pivots at the top and bottom to share the load: the upper pivot stabilizes the upper part of the door panel through the pivot and the rotating groove, while the lower pivot uses the cooperation of the ball and the ball groove to distribute the pressure on the lower part of the door panel, resulting in a more balanced overall force and extended service life.

[0019] 3. Enhanced structural strength

[0020] The upper and lower connectors adopt an L-shaped design and are fixed to the top / bottom and side of the door panel for a more stable connection.

[0021] Reinforcing ribs are added to the connectors to further enhance the structure's resistance to deformation and meet the needs of long-term use.

[0022] 4. Reliable installation and limit switches

[0023] The upper pivot is fixed by a limit block to prevent the door panel from shifting when rotating; the lower pivot is embedded in the ground by a lower fixing block, and the rotating seat cooperates with the ball to ensure the stability of the door panel when rotating.

[0024] The overall installation process is clear, and the connection structure of each component is simple and robust, reducing the cost of later maintenance.

[0025] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0036] Please see Figure 1-3 The door hinge structure shown in a preferred embodiment of this application includes an upper hinge and a lower hinge respectively disposed at the top and bottom of the door panel 4, wherein:

[0037] The upper pivot includes an upper fixing block 1, a limiting block 2, and an upper connecting piece 3. The upper connecting piece 3 has an L-shaped structure and is threaded to the top and side of the door panel 4 with screws. The top of the upper connecting piece 3 is provided with a pivot.

[0038] Furthermore, a rotating groove corresponding to the rotating shaft is provided on one side of the upper fixing block 1. The upper fixing block 1 and the upper connecting piece 3 are rotatably connected through the rotating shaft and the rotating groove. One end of the limiting block 2 is provided with a shaft hole corresponding to the rotating shaft. The limiting block 2 is sleeved on the rotating shaft through the shaft hole. The other end of the limiting block 2 is threadedly connected to the upper fixing block 1 by a bolt, thereby limiting the upper connecting piece 3.

[0039] The lower pivot includes a lower connector 5, a lower fixing block 6, a ball 7, and a rotating seat 8. The lower connector 5 is also an L-shaped structure and is threaded to the bottom and side of the door panel 4 with screws. The bottom of the lower connector 5 is provided with a concave ball groove, in which the ball 7 rotates. The top of the rotating seat 8 is also provided with a concave ball groove corresponding to the ball 7. The bottom of the rotating seat 8 is provided with an installation shaft.

[0040] Furthermore, the lower fixing block 6 is embedded in the ground during construction, and the top of the lower fixing block 6 is provided with an installation groove corresponding to the installation shaft, and is fixedly connected to the rotating seat 8 through this structure.

[0041] Preferably, the lower connector 5 and the upper connector 3 are provided with reinforcing ribs to enhance the structural strength.

[0042] Working principle:

[0043] Before installing the door panel 4, fix the upper fixing block 1 on the wall or door frame, and embed the lower fixing block 6 into the corresponding underground part through construction. Install the rotating seat 8 and the ball 7 in sequence, and then fix the upper connector 3 and the lower connector 5 at the upper and lower ends of the door panel 4.

[0044] Subsequently, the door panel 4 is rotatably connected to the lower pivot by the cooperation of the concave ball groove of the lower connector 5 and the ball 7, and the pivot of the upper connector 3 is inserted into the rotating groove. Finally, the door panel 4 is fixed and limited by the limiting block 2, and the installation is completed.

[0045] Please see Figure 4-5 Traditional hinge 10 hinges have a large gap when opening and closing, which poses a safety hazard. However, with the door hinge structure shown in this application, the gap between the door panel 4 and the wall panel 9 is greatly reduced, and the overall stress is evenly distributed. The situation where the door panel 4 tilts and causes the hinge 10 to be damaged will not occur, which is a significant improvement.
