Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge that can rotate 360 ​​degrees. Background Technology

[0002] In existing technologies, hinge mechanisms often employ a single stop plate type angle limiting structure to control the rotation range. This type of structure typically features an arc-shaped groove or arc-shaped protrusion at a specific angle on the stop plate body, with a corresponding mating part on the hinge shaft. The mating part and the arc-shaped groove or protrusion create a rigid mechanical contact, thereby limiting the hinge's rotation range. However, due to the presence of the arc-shaped grooves and protrusions, a certain amount of physical space is required, which directly results in the rotation range being strictly limited to a specific angle range. It is impossible to achieve 360-degree full-circumference free rotation and can only provide a limit function for a single angle range, making it difficult to meet the needs of segmented multi-angle limit or large-range adjustable limit. Utility Model Content

[0003] Based on this, the present invention provides a 360-degree rotatable hinge with a simple structure and convenient use. Through the angle limiting cooperation between the first and second locking blocks and the rotation range limitation between the limiting block and the limiting groove, the coordinated linkage between the first stop plate, the second stop plate and the free support is realized, enabling the free support to rotate freely 360 degrees relative to the fixed support, which can adapt to the application requirements of different angle ranges.

[0004] To achieve the objectives of this utility model, the following technical solution is adopted: A 360-degree rotatable hinge, comprising: Fixed bracket; The pivot shaft that connects to the fixed bracket; A first stop plate is coaxially fixedly connected to the rotating shaft; a first locking block is provided on the outer peripheral surface of the first stop plate. A second stop plate rotatably sleeves the rotating shaft; a second locking block protrudes from the periphery of the end of the second stop plate facing the first stop plate, the second locking block and the first locking block are on the same circumferential trajectory, and the second locking block is used to abut against the first locking block; a limiting groove with an arc shape is provided on the periphery of one side of the second stop plate; and A free bracket that can be rotatably connected to a rotating shaft; a limiting block is protruding from the side of the free bracket facing the second stop plate, the limiting block is matched and accommodated inside the limiting groove, and the limiting block is used to abut against the opposite side walls of the limiting groove. The relative rotation angle range between the first stop plate and the second stop plate is superimposed on the relative rotation angle range between the free support and the second stop plate to achieve 360-degree rotation of the free support relative to the fixed support.

[0005] The aforementioned 360-degree rotatable hinge has a simple structure and is easy to use. Through the angle limiting cooperation between the first and second locking blocks and the rotation range limitation between the limiting block and the limiting groove, the coordinated linkage between the first stop plate, the second stop plate, and the free support is realized, enabling the free support to rotate freely 360 degrees relative to the fixed support, which can adapt to application needs with different angle ranges.

Detailed Implementation

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] Please see Figures 1 to 4 The present invention provides a 360-degree rotatable hinge, comprising a fixed bracket 10, a rotating shaft 20 connected to the fixed bracket 10, a first stop plate 30 coaxially fixedly connected to the rotating shaft 20, a second stop plate 40 rotatably sleeved on the rotating shaft 20, a free bracket 50 rotatably connected to the rotating shaft 20, and a stop assembly 60 connected to the portion of the rotating shaft 20 that protrudes beyond the free bracket 50; the stop assembly 60 elastically engages with the free bracket 50 to position the rotation of the free bracket 50.

[0018] In this embodiment, the cross-section of the rotating shaft 20 is a rounded rectangle.

[0019] The outer peripheral surface of the first stop plate 30 is provided with a first locking block 31 protruding outward; the middle part of the first stop plate 30 is provided with a first through hole in the shape of a rounded rectangle. The opening contour of the first through hole is consistent with the outer peripheral contour of the rotating shaft 20. The first through hole is used to match and accommodate the rotating shaft 20 to pass through, so as to realize the coaxial fixed connection between the first stop plate 30 and the rotating shaft 20, so that the positions of the first stop plate 30 and the rotating shaft 20 are relatively fixed and there is no relative rotation.

[0020] The second stop plate 40 has a second locking block 41 protruding from its periphery at the end facing the first stop plate 30. The second locking block 41 is used to abut against the first locking block 31. The second stop plate 40 has a second circular through hole in its middle, which is used for the rotating shaft 20 to pass through, so that the second stop plate 40 and the rotating shaft 20 can rotate relative to each other, that is, the second stop plate 40 and the first stop plate 30 can rotate relative to each other.

[0021] like Figure 2 As shown, the second locking block 41 and the first locking block 31 are on the same circumferential trajectory. When the second stop plate 40 and the first stop plate 30 rotate relative to each other, the rigid contact between the second locking block 41 and the first locking block 31 can precisely limit the angle range of their relative rotation.

[0022] In this embodiment, the relative rotation angle between the first card block 31 and the second card block 41 is 0-270 degrees.

[0023] Furthermore, the periphery of the side of the second stop plate 40 facing the free support 50 is provided with an arc-shaped limiting groove 42, which is used to match the free support 50.

[0024] A limiting block 51 protrudes from the side of the free support 50 facing the second stop plate 40. The limiting block 51 is fitted into the interior of the limiting groove 42 and abuts against the opposite side walls of the limiting groove 42 to limit the angular range of relative rotation between the free support 50 and the second stop plate 40. A circular through hole is provided in the middle of the free support 50 for the rotating shaft 20 to pass through, so as to facilitate relative rotation between the free support 50 and the rotating shaft 20; the limiting block 51 is located on one side of the through hole.

[0025] In this embodiment, the rotation angle range of the limiting block 51 within the limiting groove 42 is 0-90 degrees.

[0026] Thus, through the angular limiting cooperation of the first locking block 31 and the second locking block 41, and the rotation range limitation of the limiting block 51 and the limiting groove 42, the superposition of the two maximum rotation angles realizes the coordinated linkage between the first stop plate 30, the second stop plate 40 and the free bracket 50, and enables the free bracket 50 to rotate freely 360 degrees relative to the fixed bracket 10.

[0027] Furthermore, in this embodiment, the free bracket 50 has a plurality of recesses 52 evenly spaced around the perforation on the side facing the cam 60, the recesses 52 being used to match the gear assembly 60.

[0028] The gear shifting assembly 60 includes a cam 61, a portion of the rotating shaft 20 extending beyond the free support 50, a spring element 62 and a washer 63, and a nut 64 screwed to the end of the rotating shaft 20. The spring element 62 is sandwiched between the washer 63 and the cam 61. Under the elastic force of the spring element 62, the spring element 62 drives the cam 61 to always elastically abut against the free support 50, thereby realizing gear shifting at different angles of the free support 50.

[0029] Specifically, protrusions 610 are provided on opposite sides of the end face of the cam 61 facing the free bracket 50. The protrusions 610 are used to match and embed into the interior of the recess 52 to realize the positioning and engagement of the free bracket 50 and the cam 61, thereby realizing the gear switching of the free bracket 50 at different angles.

[0030] In this embodiment, there are four recesses 52, so that the angle difference between adjacent stops of the free bracket 50 rotation is 90 degrees.

[0031] In this embodiment, the elastic element 62 can be a sheet, a wave spring, or a spring, or any other component with elastic extension function, as long as it can achieve the same elastic driving effect, thus having good versatility.

[0032] The aforementioned 360-degree rotatable hinge has a simple structure and is easy to use. Through the angle limiting cooperation between the first locking block 31 and the second locking block 41, and the rotation range limitation between the limiting block 51 and the limiting groove 42, the coordinated linkage between the first stop plate 30, the second stop plate 40, and the free support 50 is realized, enabling the free support 50 to rotate freely 360 degrees relative to the fixed support 10, which can adapt to application needs with different angle ranges.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
