Description

Technical Field

[0001] This invention belongs to the field of mechanical parts technology, and in particular relates to a hinge structure that can rotate 360 ​​degrees. Background Technology

[0002] Hinges are mechanical devices used to connect two solids and allow relative rotation between them. For example, hinges are used in car doors and the installation of doors in industrial chassis and cabinets. However, most hinges have a rotation angle between 95 and 110 degrees, with some special ones having angles of 25, 30, 45, 135, 165, and 180 degrees. For applications requiring rotation of more than 180 degrees, the application range of existing hinge structures is limited. Moreover, most hinges are made of sheet metal stamping, and the pivot point is not a closed structure, resulting in limited load-bearing capacity and low safety under heavy loads. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide a hinge structure that is simple in structure, has a wide range of applications, and is particularly suitable for working conditions with large-angle rotation, and can rotate 360 ​​degrees.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a hinge structure that can rotate 360 ​​degrees, including a first hinge seat and a second hinge seat. At least one pair of U-shaped mounting grooves are arranged opposite to each other on the first hinge seat and the second hinge seat. A load-bearing block is arranged in the oppositely arranged U-shaped mounting groove. Both ends of the load-bearing block are rotatably connected to the U-shaped mounting grooves of the first hinge seat and the second hinge seat through hinge shafts. At least one pair of flexible connecting pieces are arranged crosswise on both sides of the U-shaped mounting groove. The two ends of the flexible connecting pieces are respectively fixed on the first hinge seat and the second hinge seat.

[0005] Furthermore, both the first hinge seat and the second hinge seat include an integrally formed part fixing part and a rotating connection part. The end of the rotating connection part away from the part fixing part is a concentric arc surface structure. The U-shaped mounting groove is provided on the rotating connection part. The first hinge seat and the second hinge seat are connected by a load-bearing block provided in the U-shaped mounting groove.

[0006] Furthermore, the two side walls of the U-shaped mounting groove are provided with first mounting holes, and the load-bearing block is provided with a second mounting hole corresponding to the first mounting hole. The load-bearing block is installed into the U-shaped mounting groove by rotating the hinge shaft through the first mounting hole and the second mounting hole.

[0007] Furthermore, one end of the pair of flexible connecting pieces arranged in a cross pattern is fixedly disposed on the upper and lower end surfaces of the rotating connection portion of the first hinge seat, and the other end of the pair of flexible connecting pieces passes through the gap between the first hinge seat and the second hinge seat and is fixed on the lower and upper end surfaces of the rotating connection portion of the second hinge seat.

[0008] Furthermore, the fixing part of the component is welded and fixedly connected to the component to be hinged.

[0009] Furthermore, the part fixing part is provided with bolt holes, and the part fixing part and the part to be hinged are fixedly connected by bolts through the bolt holes.

[0010] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0011] 1. The hinge structure of the present invention connects the first hinge seat and the second hinge seat through a load-bearing block, so that the first hinge seat and the second hinge seat can rotate around the hinge axis. During the hinge movement, the cross-arranged flexible connecting pieces are always under tension, ensuring that there is no relative sliding between the arc surfaces of the rotating connection part of the first hinge seat and the second hinge seat, and only a single degree of freedom of rotation. This provides a good constraint on the rotation between the first hinge seat and the second hinge seat. This hinge structure is simple and overcomes the problem that existing hinges cannot achieve 360-degree rotation. It has a wide range of applications.

[0012] 2. The rotational connection structure between the first hinge seat and the second hinge seat of the hinge structure of the present invention determines that both can rotate 360 ​​degrees around each other. Therefore, there is no need to distinguish the connection relationship between this hinge structure and the fixed and rotating parts during the installation process, which facilitates installation and enhances applicability.

[0013] 3. The hinge shaft of the hinge structure of the present invention passes through the first mounting hole and the second mounting hole to install the load-bearing block into the U-shaped mounting groove. The installation of the hinge shaft adopts a closed structure, which has a greater load-bearing capacity compared with the existing non-closed structure and is safer for heavy load conditions.

[0018] To better understand the above-mentioned objects, features, and advantages of the present invention, the following description is provided in conjunction with... Figure 1-2 The present invention will be further described in detail below with reference to specific embodiments. It should be noted that, unless otherwise specified, the technical solutions and features of the present application can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific technical solutions disclosed below.

[0020] The technical solution of the present invention will now be described with reference to specific embodiments. These embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the present invention without creative effort are within the scope of protection of the present invention.

[0021] The technical solution of the present invention provides a hinge structure that can rotate 360 ​​degrees, including a first hinge seat 1 and a second hinge seat 2. At least one pair of U-shaped mounting grooves 3 are arranged opposite to each other on the first hinge seat 1 and the second hinge seat 2. A load-bearing block 4 is arranged in the oppositely arranged U-shaped mounting grooves 3. Both ends of the load-bearing block 4 are rotatably connected to the U-shaped mounting grooves 3 of the first hinge seat 1 and the second hinge seat 2 through hinge shafts 5. At least one pair of flexible connecting pieces 6 are arranged crosswise on both sides of the U-shaped mounting grooves 3. The two ends of the flexible connecting pieces 6 are respectively fixed on the first hinge seat 1 and the second hinge seat 2.

[0022] The hinge structure of this invention connects the first hinge seat 1 and the second hinge seat 2 through a load-bearing block, allowing the first hinge seat 1 and the second hinge seat 2 to rotate around the hinge axis 5. During the hinge movement, the cross-arranged flexible connecting pieces 6 are always under tension, ensuring that there is no relative sliding between the opposing surfaces of the first hinge seat 1 and the second hinge seat 2, and that they only have a single degree of freedom of rotation. This provides a good constraint on the rotation between the first hinge seat 1 and the second hinge seat 2. This hinge structure is simple and overcomes the problem that existing hinges cannot achieve 360-degree rotation, making it widely applicable.

[0023] Furthermore, both the first hinge seat 1 and the second hinge seat 2 include an integrally formed part fixing part 7 and a rotating connection part 8. The end of the rotating connection part 8 away from the part fixing part 7 is a concentric arc surface structure. The U-shaped mounting groove 3 is provided on the rotating connection part 8. The first hinge seat 1 and the second hinge seat 2 are connected by a load-bearing block 4 provided in the U-shaped mounting groove 3.

[0024] Specifically, the part fixing part 7 is used to fix the part to be hinged, and the rotating connection part 8 is rotatably connected through the load-bearing block 4 to realize 360-degree relative rotation between the first hinge seat 1 and the second hinge seat 2. The rotating connection parts 8 of the first hinge seat 1 and the second hinge seat 2 are both set with concentric arc surface structures, so that the relative rotation between the two is smoother and more free. In addition, in actual application, the overall length of the hinge can be extended and the load-bearing capacity can be improved by adding U-shaped mounting groove 3 and setting multiple load-bearing blocks 4.

[0025] Furthermore, one end of the pair of flexible connecting pieces 6 arranged in a cross pattern is fixedly disposed on the upper and lower end surfaces of the rotating connecting portion 8 of the first hinge seat 1, and the other end of the pair of flexible connecting pieces 6 passes through the gap between the first hinge seat 1 and the second hinge seat 2 and is fixed on the lower and upper end surfaces of the rotating connecting portion 8 of the second hinge seat 2.

[0026] Specifically, the flexible connecting piece 6 is arranged in a cross pattern and is always under tension. Therefore, whether the first hinge seat 1 rotates around the second hinge seat 2 or the second hinge seat 2 rotates around the first hinge seat 1, the flexible connecting piece 6 can constrain the hinge seat. Furthermore, during the relative rotation of the first hinge seat 1 and the second hinge seat 2, the non-fixed part in the middle of the flexible connecting piece 6 always covers the arc surface structure of the rotating connection part 8, which not only realizes the non-contact rotation between the first hinge seat 1 and the second hinge seat 2, but also plays a good limiting and constraining role between the two.

[0027] Among them, the flexible connecting piece 6 is a metal or non-metal material with no extensibility or slight extensibility, and can be repeatedly bent, such as spring steel.

[0028] Furthermore, the two side walls of the U-shaped mounting groove 3 are provided with first mounting holes 9 facing each other, and the load-bearing block 4 is provided with a second mounting hole (not shown) corresponding to the first mounting hole 9. The load-bearing block 4 is rotatably installed into the U-shaped mounting groove 3 by passing the hinge shaft 5 through the first mounting hole 9 and the second mounting hole.

[0029] Specifically, the hinge shaft 5 passes through the first mounting hole 9 and the second mounting hole to install the load-bearing block 4 into the U-shaped mounting groove 3. The installation of the hinge shaft 5 adopts a closed structure, which has a greater load-bearing capacity compared with the existing non-closed structure and is safer for heavy load conditions.

[0030] Furthermore, the part fixing part 7 is welded and fixedly connected to the part to be hinged.

[0031] Furthermore, the part fixing part 7 is provided with bolt holes 10, and the part fixing part 7 and the part to be hinged are fixedly connected by bolts through the bolt holes 10.

[0032] Specifically, the part fixing part 7 can be fixed to the part to be hinged in a variety of ways. In addition to the welding connection or bolt connection disclosed in this invention, any way that can achieve the fixed connection between the two falls within the scope of this invention.

[0033] Example

[0034] like Figure 1 As shown, a hinge structure capable of 360-degree rotation includes a first hinge seat and a second hinge seat. Two pairs of U-shaped mounting grooves are arranged opposite each other on the first and second hinge seats. Each pair of U-shaped mounting grooves contains a load-bearing block. Both ends of the load-bearing blocks are rotatably connected to the U-shaped mounting grooves of the first and second hinge seats via hinge shafts. A pair of flexible connecting pieces are arranged crosswise on both sides of each U-shaped mounting groove. The two ends of the flexible connecting pieces are respectively fixed to the first and second hinge seats. Bolt holes are provided on the component fixing parts of the first and second hinge seats for bolt connection with the components to be hinged.

[0035] like Figure 2 As shown, the first hinge seat is fixed and the second hinge seat rotates around the first hinge seat, and the process state diagram shows the gradual rotation from the initial 0 degrees to 360 degrees, with each state separated by 90 degrees.

[0036] This invention has a simple structure and is easy to operate. It overcomes the problem that existing hinges cannot achieve 360-degree rotation. It has a wide range of applications, strong load-bearing capacity, and is safer and more reliable.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
