Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a door closing hinge. Background Technology

[0002] Traditional door hinges mostly use a metal pivot structure. While they enable the door to open and close, they lack an effective buffering mechanism when the door closes, making the door prone to violent impacts due to inertia. Especially in heavy-duty doors or frequently used scenarios, rigid closure not only generates noise pollution, but long-term impacts can also cause door panel deformation, hinge loosening, and even parts falling off, affecting the door's lifespan.

[0036] Please see below. Figures 1-4 The present invention provides a door hinge, specifically comprising:

[0037] Mounting base 10;

[0038] The pivot 20 has one end fixedly connected to the door body and the other end set on the mounting base 10 and rotates around the first direction. The surface of the pivot 20 is provided with a protruding structure 21; wherein, the first direction is the axis of the pivot 20.

[0039] The elastic component 30 is disposed in the mounting base 10 and moves linearly along the second direction under the action of the rotating shaft 20. One end of the elastic component 30 is provided with an abutting part 31 for abutting the protruding structure 21, and the other end is fixed in the mounting base 10; wherein, the second direction is the radial direction of the rotating shaft.

[0040] In this embodiment, by rotating the pivot 20 connected to the door body onto the mounting base 10, and providing a protruding structure 21 on the pivot 20 to cooperate with the abutment portion 31 of the elastic component 30, the protruding structure 21 drives the elastic component 30 to move in a straight line during the opening and closing of the door. This allows the elasticity of the elastic component 30 to effectively buffer the inertia of the door during opening and closing, reducing impact force, extending the service life of the door, and also effectively reducing noise and wear, thus improving the user experience.

[0041] Combination Figures 5-7 As shown, in one embodiment, the protrusion structure 21 includes a pivot groove 211 and first protrusions 212 symmetrically disposed on both sides of the pivot groove 211;

[0042] The abutment portion 31 is provided with a second protrusion 311 that matches the shaft groove 211.

[0043] In this embodiment, the protruding structure 21 comprises a pivot groove 211 and first protrusions 212 symmetrically arranged on both sides of the pivot groove 211. The abutment portion 31 cooperates with the protruding structure 21 to compress the elastic component 30, thereby buffering the door.

[0044] For example, when the door is opened, the second protrusion 311 on the abutment 31 fits tightly with the shaft groove 211 to ensure the stability of the door; when the door is closed, the shaft 20 rotates and pushes the abutment 31 through the first protrusion 212, causing the elastic component 30 to be compressed, thereby providing cushioning.

[0045] Of course, in specific application scenarios, it can also be set so that when the door is closed, the second protrusion 311 fits tightly with the pivot groove 211 to ensure the stability of the door. When the door is opened, the pivot 20 rotates and pushes the abutment 31 through the first protrusion 212, so that the elastic component 30 is compressed, thereby providing cushioning.

[0046] In one embodiment, the mounting base 10 is provided with a first mounting hole 11 for mounting the rotating shaft 20 and a second mounting hole 12 for mounting the elastic component 30. The opening of the first mounting hole 11 is located at the top of the mounting base 10, and the opening of the second mounting hole 12 is located on the side wall of the mounting base 10 away from the first mounting hole 11. The axis of the first mounting hole 11 and the axis of the second mounting hole 12 are perpendicular to each other.

[0047] In this embodiment, a first mounting hole 11 is provided on the top of the mounting base 10 for mounting the rotating shaft 20 and providing rotational support for the rotating shaft 20. A second mounting hole 12 perpendicular to the first mounting hole 11 is provided on the side wall of the mounting base 10 for mounting the elastic component 30 and ensuring its linear movement along the second direction, thereby buffering the door body with the cooperation of the rotating shaft 20 and the elastic component 30.

[0048] In one embodiment, the lower end of the rotating shaft 20 is rotatably connected to the first mounting hole 11, and the upper end of the rotating shaft 20 is used to connect to the door body.

[0049] Preferably, a bearing mounting position is provided at the bottom of the first mounting hole 11, and a rotating bearing 13 corresponding to the bearing mounting position is provided between the rotating shaft 20 and the mounting base 10.

[0050] In this embodiment, the lower end of the rotating shaft 20 is rotatably connected to the mounting base 10 through the first mounting hole 11, while the upper end is fixedly connected to the door body. Thus, the movement of the door body drives the rotation of the rotating shaft 20 within the mounting base 10. Furthermore, by providing a bearing mounting position at the bottom of the first mounting hole 11 and a corresponding rotating bearing 13 between the rotating shaft 20 and the mounting base 10, friction between the rotating shaft 20 and the mounting base 10 during rotation can be reduced, improving rotational flexibility, ensuring smooth opening and closing of the door body, and extending the service life of the overall structure. In a specific embodiment, a bearing mounting position can also be provided at the top of the first mounting hole 11, with a corresponding rotating bearing 13, thereby further improving rotational stability and reducing wear.

[0051] In one embodiment, the elastic component 30 further includes a spring 32 and a fixing member 33, with the two ends of the spring 32 abutting against the abutting portion 31 and the fixing member 33 respectively, and the fixing member 33 being fixed to the open end of the second mounting hole 12.

[0052] In this embodiment, the elastic component 30 comprises an abutment portion 31, a spring 32, and a fixing member 33. The elastic component 30 abuts against the protruding structure 21 of the rotating shaft 20 and one end of the spring 32 via the abutment portion 31, while the other end of the spring 32 abuts against the fixing member 33. The elastic component 30 further restricts the spring 32 within the second mounting hole 12 by fixing the fixing member 33 to the open end of the second mounting hole 12. This ensures that the spring 32 can be effectively compressed and rebounded under the push of the abutment portion 31 when the door moves, thereby providing a stable buffering effect, reducing impact force, protecting the door and mounting structure, and extending their service life. In specific application scenarios, the elastic coefficient and length of the spring 32 can be adjusted according to the weight of the door and the opening and closing frequency to ensure the best buffering effect.

[0053] In one embodiment, the two ends of the abutting part 31 abut against the protruding structure 21 and the spring 32 respectively, and the end of the abutting part 31 that abuts against the spring 32 is provided with a groove-shaped spring mounting position 312.

[0054] In this embodiment, the abutment part 31 precisely fixes the position of the spring 32 through the groove-shaped spring mounting position 312, ensuring that the spring 32 remains stable during compression and rebound, further optimizing the buffering effect and improving the smoothness of the door opening and closing.

[0055] In one embodiment, the opening end of the second mounting hole 12 is provided with a threaded structure, and the fastener 33 is fixed in the second mounting hole 12 by cooperating with the threaded structure.

[0056] In this embodiment, the fixing member 33 is tightly engaged with the second mounting hole 12 through a threaded structure, thereby restricting the movement of the spring 32 during the movement process and ensuring that the spring 32 can be effectively compressed and rebounded under the push of the abutment part 31.

[0057] In one embodiment, the door hinge also includes an outer housing 40 covering the mounting base 10.

[0058] In this embodiment, by providing a cover outside the housing 40 of the mounting base 10, it can not only prevent dust and dirt, thereby protecting the structural safety of the internal components, but also improve the aesthetics of the overall structure.

[0059] In one embodiment, a support rod 41 for supporting the elastic component 30 is provided on the outer shell 40 in a horizontal direction. The support rod 41 extends from one inner side of the outer shell 40 through the mounting base 10 and is connected to the other inner side of the outer shell 40.

[0060] In this embodiment, a support rod 41 is provided horizontally through the mounting base 10 between the inner sides of the outer shell 40, thereby providing support force to support the weight of the elastic component 30, ensuring that the elastic component 30 remains stable during the opening and closing of the door, reducing displacement caused by gravity, further optimizing the buffering effect, and improving the durability and stability of the overall structure.
