Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotating shaft technology, specifically to a rotating shaft with an internal shaft core. Background Technology
[0002] A hinge typically connects two frames or plate-like structures, allowing them to unfold and fold. The size of the hinge generally varies depending on the size of the product being installed. In existing hinges, the core is located on the outside of the hinge, whether unfolded or closed. This makes it difficult to stack multiple hinges when transporting them, taking up space and making transportation inconvenient. Furthermore, the externally located core is more susceptible to damage from impacts. Therefore, a hinge with an internal core is needed to solve these problems. Utility Model Content

[0004] The device includes a right shaft plate and a left shaft plate disposed on one side of the right shaft plate. The right shaft plate and the left shaft plate are attached to each other, one on the left and one on the right. Arc-shaped openings are provided on the front and rear sides of the right shaft plate and the left shaft plate. The arc-shaped openings of the right shaft plate and the left shaft plate are joined together to form a semi-circular arc-shaped groove. The front and rear arc-shaped grooves of the right shaft plate and the left shaft plate are configured as a front groove and a rear groove. A shaft core assembly is disposed inside the rear groove at one end of the right shaft plate and the left shaft plate.
[0005] Furthermore, the shaft core assembly includes a right shaft core fixed to one end of the right shaft plate and a left shaft core fixed to one end of the left shaft plate, with the left shaft core and the right shaft core arranged one above the other.
[0006] Furthermore, the left and right shaft cores are configured as cylindrical structures, and each has a shaft core hole in the middle.
[0007] Furthermore, a shaft is rotated between the shaft holes of the left shaft core and the right shaft core.
[0008] Furthermore, portions of the left and right shaft cores are located inside the rear groove.
[0009] Furthermore, the right shaft plate and the left shaft plate are respectively provided with a right limiting block and a left limiting block at one end of the front groove.

It should be noted that the method steps described herein can be implemented by any functional block or functional arrangement, and any functional block or functional arrangement can be implemented as a physical entity or a logical entity, or a combination of both.
[0033] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Note: The examples described below are merely specific examples and are not intended to limit the embodiments of this utility model to the specific steps, values, conditions, data, order, etc. Those skilled in the art can utilize the concept of this utility model to construct more embodiments not mentioned herein by reading this specification.
[0035] A hinge typically connects two frames or plate-like structures, allowing them to unfold and fold. The size of the hinge generally varies depending on the size of the product being installed. In existing hinges, the core is located on the outside of the hinge, whether unfolded or closed. This makes it difficult to stack multiple hinges when transporting them, taking up space and making transportation inconvenient. Furthermore, the externally located core is more susceptible to damage from impacts. Therefore, a hinge with an internal core is needed to solve these problems.
[0036] To address the aforementioned problems with the rotating shaft, this utility model proposes a rotating shaft with an internal shaft core.
[0037] In the first embodiment, please refer to Figure 1 , Figure 2 and Figure 3 It includes a right shaft plate 1 and a left shaft plate 4 located on one side of the right shaft plate 1. The right shaft plate 1 and the left shaft plate 4 fit together on the left and right sides respectively. Arc-shaped openings are provided on the front and rear sides of the right shaft plate 1 and the left shaft plate 4. The arc-shaped openings of the right shaft plate 1 and the left shaft plate 4 are joined together to form a semi-circular arc-shaped groove. The front and rear arc-shaped grooves of the right shaft plate 1 and the left shaft plate 4 are set as a front groove and a rear groove. A shaft core assembly is provided inside the rear groove at one end of the right shaft plate 1 and the left shaft plate 4.
[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the right shaft plate 1 and the left shaft plate 4 are symmetrically arranged, one on the left and one on the right. Both ends of the right shaft plate 1 and the left shaft plate 4, and the side where they fit together, are provided with arc-shaped openings. When the two arc-shaped openings are joined together, they form a semi-circular arc-shaped groove. That is, the front and rear arc-shaped grooves of the right shaft plate 1 and the left shaft plate 4 are set as a front groove and a rear groove. A shaft core assembly is provided at one end of the right shaft plate 1 and the left shaft plate 4. The shaft core assembly is located inside the rear groove and can rotate inside the rear groove. This allows the right shaft plate 1 and the left shaft plate 4 to wrap the shaft core assembly inside, saving space, facilitating transportation, and protecting the shaft core assembly.
[0039] Please see Figure 1 and Figure 2 The shaft core assembly includes a right shaft core 2 fixed to one end of the right shaft plate 1 and a left shaft core 5 fixed to one end of the left shaft plate 4. The left shaft core 5 and the right shaft core 2 are arranged one above the other. The left shaft core 5 and the right shaft core 2 are set as cylindrical structures, and each has a shaft core hole 7 in the middle. A shaft rod is rotated between the shaft core holes 7 of the left shaft core 5 and the right shaft core 2. Parts of the left shaft core 5 and the right shaft core 2 are located inside the rear groove.
[0040] like Figure 1 and Figure 2 As shown, the left shaft core 5 and the right shaft core 2 are arranged one above the other and are both cylindrical. The shaft core holes 7 in the middle are corresponding to each other. The shaft core holes 7 of the left shaft core 5 and the right shaft core 2 are equipped with shaft rods inside, which limit the left shaft core 5 and the right shaft core 2, so that the left shaft core 5 and the right shaft core 2 can rotate clockwise / counterclockwise respectively, which facilitates the opening and closing of the right shaft plate 1 and the left shaft plate 4.
[0041] Please refer to 1. Figure 2 and Figure 4 Right shaft plate 1 and left shaft plate 4 are respectively provided with right limiting block 3 and left limiting block 6 at one end of the front groove. Left limiting block 6 and right limiting block 3 are arranged one above the other and are located inside the front groove. Limiting holes 8 are opened on the top of left limiting block 6 and right limiting block 3. Limiting rods are provided inside the limiting holes 8 of left limiting block 6 and right limiting block 3. Left lamp plate 9 and right lamp plate 10 are respectively fixed on one side of right shaft plate 1 and left shaft plate 4.
[0042] like Figure 1 , Figure 2 and Figure 4As shown, right limiting block 3 and left limiting block 6 are respectively provided at one end of the front groove of right shaft plate 1 and left shaft plate 4. Right limiting block 3 and left limiting block 6 are arranged one above the other, and right limiting block 3 and left limiting block 6 are arranged in opposite positions to right shaft core 2 and left shaft core 5. For example, if left shaft core 5 is located above one end of left shaft plate 4, left limiting block 6 is located below the other end of left shaft plate 4. Both left limiting block 6 and right limiting block 3 have limiting holes 8 at their tops, and limiting rods are engaged inside them. That is, after left shaft plate 4 and right shaft plate 1 are unfolded, they are fixed. In this application, left lamp plate 9 and right lamp plate 10 are respectively fixed on one side of right shaft plate 1 and left shaft plate 4, and the lamp plates of this rotating shaft are including but not limited to this structure.
[0043] In the second embodiment, please refer to Figure 5 The area between the right shaft plate 1 and the left shaft plate 4 and the right shaft core 2 and the left shaft core 5 can form a folding area.
[0044] like Figure 5 As shown, in the second embodiment, the right shaft plate 1 and left shaft plate 4 are longer than those in the first embodiment. When closed, the right shaft plate 1 and left shaft plate 4 form a wider folding area, allowing the plate to be folded between the right shaft plate 1 and left shaft plate 4, forming a three-fold structure. In the second embodiment, the right shaft core 2 and left shaft core 5 on the right shaft plate 1 and left shaft plate 4 are arranged one above the other, both forming a bearing structure.
[0045] When using this utility model, after the left shaft plate 4 and the right shaft plate 1 are closed, the shaft core assembly is wrapped by the left shaft plate 4 and the right shaft plate 1, which can protect the shaft core assembly, save space, and facilitate transportation.
