Refrigerator variable-rail hinge rotating shaft

Abstract

This utility model discloses a refrigerator variable-track hinge shaft, relating to the field of refrigerator hinges. The refrigerator variable-track hinge shaft includes a first shaft and a second shaft, which are inserted into the refrigerator frame and are drively connected to the inner door of the refrigerator door. This refrigerator variable-track hinge shaft achieves dual-axis linkage through the first and second shafts, making the rotation trajectory of the inner door closer to the refrigerator frame. When the inner door is rotated, the first shaft rotates at the end of the first track, while the second shaft slides along the third track, allowing the inner door to rotate at a large angle of 90° to 180° relative to the refrigerator frame. This allows the refrigerator door to move along a specific variable-track trajectory during opening, reducing the space occupied on both sides.

Description

Technical Field

[0001] This utility model relates to the field of refrigerator hinge technology, specifically a refrigerator variable track hinge pivot. Background Technology

[0002] The refrigerator hinge is the core hardware component that connects the refrigerator door to the refrigerator body. Its performance directly affects the door's closing stability, sealing, and service life.

[0003] In the prior art, refrigerator hinges are usually traditional single-axis hinges. The refrigerator door rotates through the hinge and hinge axis. The maximum opening angle of a normal refrigerator hinge is usually around 110°. Due to the space between the refrigerator and the refrigerator door, it cannot rotate at a large angle. This application designs a variable track hinge that can open at a large angle without obstruction. The opening and closing angle can reach 90° to 180°. During the opening process, the refrigerator door can move according to a specific variable track trajectory, reducing the space occupied on both sides. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a variable-track hinge shaft, which solves the problem that refrigerator hinge shafts are usually traditional single shafts, and the refrigerator door rotates through the hinge and hinge shaft. The maximum opening angle of ordinary refrigerator hinges is usually around 110°, which is affected by the space between the refrigerator and the refrigerator door, making it impossible to rotate at a large angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigerator variable-track hinge shaft, comprising a first shaft and a second shaft, the first shaft and the second shaft being inserted into the refrigerator body frame, the first shaft and the second shaft being drivenly connected to the inner side of the refrigerator door, the inner side of the refrigerator door having a first track and a second track, the first shaft being inserted into the first track, the second shaft being inserted into the second track, and the inner side of the refrigerator door having a third track, the third track being connected to the second track.

[0006] Preferably, the refrigerator frame is installed with the refrigerator body, and the inner door of the refrigerator is installed with the refrigerator cabinet door.

[0007] Preferably, a hinge unit is provided between the inner door body of the refrigerator door and the refrigerator body frame. The hinge unit includes a first hinge head and a second hinge head, which are respectively installed on the inner door body of the refrigerator door and the refrigerator body frame.

[0008] Preferably, both the first hinge head and the second hinge head are provided with mounting holes, and the first hinge head and the second hinge head are installed to the corresponding inner door body of the refrigerator door and the refrigerator body frame by bolts and mounting holes.

[0009] Preferably, a first connecting seat is provided on the outer wall of the first hinge head, and a first connecting shaft is rotatably connected to the first connecting seat.

[0010] Preferably, a second connecting seat is provided on the outer wall of the second hinge head, and a second connecting shaft is rotatably connected to the second connecting seat.

[0011] Preferably, the other end of the second connecting shaft is rotatably connected to the other end of the first connecting shaft.

[0012] This utility model discloses a refrigerator sliding hinge pivot, which has the following beneficial effects:

[0013] The refrigerator's variable-track hinge pivot is linked by a first pivot and a second pivot. This allows the inner door of the refrigerator to rotate closer to the refrigerator frame, preventing the inner door from colliding with the wall. When the first pivot slides to the end of the first track, the second pivot is at the end of the second track and at the beginning of the third track. Continuing to rotate the inner door causes the first pivot to rotate at the end of the first track while the second pivot slides along the third track, allowing the inner door to rotate at a large angle of 90° to 180° relative to the refrigerator frame. This allows the refrigerator door to move along a specific variable-track trajectory during opening, reducing the space occupied on both sides. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application embodiment provides a variable-track hinge pivot, solving the problem that refrigerator hinge pivots are typically traditional single-axis, with the refrigerator door rotating via a hinge and hinge pivot. The maximum opening angle of a typical refrigerator hinge is usually around 110°, and its rotation is limited by the space between the refrigerator and the door. The new embodiment achieves dual-axis linkage through a first pivot 21 and a second pivot 22. This allows the inner door 1 to rotate closer to the refrigerator frame 2, preventing the inner door 1 from colliding with the wall. When the first pivot 21 slides onto the first track 11... When the second rotating shaft 22 is at the end of the second track 12 and at the beginning of the third track 13, the inner door body 1 of the refrigerator door continues to rotate, so that the first rotating shaft 21 rotates at the end of the first track 11, while the second rotating shaft 22 slides along the third track 13, so that the inner door body 1 of the refrigerator door rotates at a large angle of 90° to 180° relative to the refrigerator frame 2. Through the inner door body 1 of the refrigerator door, the refrigerator door can move according to a specific track-changing trajectory during the opening process, reducing the space occupied on both sides.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model discloses a refrigerator reversing hinge shaft.

[0024] Example 1: According to the appendix Figure 1-4As shown, the refrigerator includes a first rotating shaft 21 and a second rotating shaft 22, which are inserted into the refrigerator body frame 2. The first rotating shaft 21 and the second rotating shaft 22 are connected to the inner door body 1 of the refrigerator door. The inner door body 1 of the refrigerator door has a first track 11 and a second track 12. The first rotating shaft 21 is inserted into the first track 11, and the second rotating shaft 22 is inserted into the second track 12. The inner door body 1 of the refrigerator door has a third track 13, which is connected to the second track 12.

[0025] The refrigerator frame 2 is installed with the refrigerator body, and the inner door 1 of the refrigerator door is installed with the refrigerator cabinet door.

[0026] When the inner door 1 of the refrigerator door rotates along the refrigerator frame 2, the first rotating shaft 21 slides along the first track 11 and the second rotating shaft 22 slides along the second track 12. At this time, the first track 11 limits the sliding path of the first rotating shaft 21 and the second track 12 limits the sliding path of the first rotating shaft 21. The sliding paths of the first rotating shaft 21 and the second rotating shaft 22 are limited, thereby limiting the rotation path of the inner door 1 of the refrigerator door relative to the refrigerator frame 2.

[0027] By using the first rotating shaft 21 and the second rotating shaft 22 for dual-axis linkage, the rotation trajectory of the inner door 1 of the refrigerator door is made closer to the refrigerator frame 2, thus preventing the inner door 1 of the refrigerator door from colliding with the wall.

[0028] When the first rotating shaft 21 slides to the end of the first track 11, the second rotating shaft 22 is at the end of the second track 12 and at the initial position of the third track 13. At this time, the inner door body 1 of the refrigerator door continues to rotate, so that the first rotating shaft 21 rotates at the end of the first track 11, while the second rotating shaft 22 slides along the third track 13, so that the inner door body 1 of the refrigerator door rotates at a large angle of 90° to 180° relative to the refrigerator frame 2. Through the inner door body 1 of the refrigerator door, the refrigerator door can move according to a specific track-changing trajectory during the opening process, reducing the space occupied on both sides.

[0029] Example 1: According to the appendix Figure 1-4 As shown, the refrigerator includes a first rotating shaft 21 and a second rotating shaft 22, which are inserted into the refrigerator body frame 2. The first rotating shaft 21 and the second rotating shaft 22 are connected to the inner door body 1 of the refrigerator door. The inner door body 1 of the refrigerator door has a first track 11 and a second track 12. The first rotating shaft 21 is inserted into the first track 11, and the second rotating shaft 22 is inserted into the second track 12. The inner door body 1 of the refrigerator door has a third track 13, which is connected to the second track 12.

[0030] A hinge unit 3 is provided between the inner door body 1 of the refrigerator door and the refrigerator frame 2. The hinge unit 3 includes a first hinge head 31 and a second hinge head 32, which are respectively installed on the inner door body 1 of the refrigerator door and the refrigerator frame 2.

[0031] The first hinge 31 and the second hinge 32 are both provided with mounting holes. The first hinge 31 and the second hinge 32 are installed with the corresponding inner door body 1 of the refrigerator door and the refrigerator frame 2 by means of bolts and mounting holes.

[0032] A first connecting seat 33 is provided on the outer wall of the first hinge head 31, and a first connecting shaft 35 is rotatably connected to the first connecting seat 33.

[0033] A second connecting seat 34 is provided on the outer wall of the second hinge head 32, and a second connecting shaft 36 is rotatably connected to the second connecting seat 34.

[0034] When the inner door 1 of the refrigerator door is rotated, the first hinge 31 rotates relative to the second hinge 32, causing the first connecting seat 33 to drive the first connecting shaft 35 to rotate, and causing the first connecting shaft 35 to drive the second connecting shaft 36 to rotate relative to the second connecting seat 34.

[0035] This allows the hinge unit 3 to work in conjunction with the first rotating shaft 21 and the second rotating shaft 22 to achieve dual-axis linkage, making the rotation of the inner door 1 of the refrigerator door relative to the refrigerator frame 2 more stable.

[0036] The other end of the second connecting shaft 36 is rotatably connected to the other end of the first connecting shaft 35. Under the action of the first connecting shaft 35 and the second connecting shaft 36, the connection between the inner door body 1 of the refrigerator door and the refrigerator frame 2 is more stable, and the inner door body 1 of the refrigerator door and the refrigerator frame 2 are more stable when rotating.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
