[0029] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 5 The rotating handle 1000 includes a housing assembly 1, a rotating assembly 2, and an elastic assembly 3. The housing assembly 1 has a receiving cavity 11 and a rotating groove 12, with the rotating groove 12 communicating with the receiving cavity 11. The rotating assembly 2 is rotatably disposed in the receiving cavity 11 and includes a rotating shaft 21 and a rod 22. The rotating shaft 21 is rotatably disposed in the receiving cavity 11, one end of the rod 22 is disposed on the rotating shaft 21, and the other end of the rod 22 extends out of the receiving cavity 11 from the rotating groove 12. The other end of the rod 22 is provided with a grip portion 23 for the user to hold. The elastic assembly 3 is placed between the rod 22 and the housing so that the side of the rod 22 away from the elastic assembly 3 presses against the inner wall of the receiving cavity 11. The stable and continuous pressing force provided by the elastic assembly 3 on the rod 22 ensures that the rod 22 always remains in contact with the inner wall of the housing, preventing wobbling due to wear and other problems. Furthermore, under the combined frictional force of the elastic component 3, the rod 22, and the inner wall of the housing, the rod 22 can achieve a frictional positioning effect during rotation.

[0032] Understandably, in order to ensure that the elastic component 3 provides a continuous abutting force to the rod 22, the elastic component 3 should be in a compressed state when it is assembled between the rod 22 and the inner wall of the accommodating cavity 11. In other words, the elastic component 3 has a tendency to push the rod 22 and the inner wall of the accommodating cavity 11 away from each other.

[0033] It should be noted that the elastic component 3 includes, but is not limited to, springs, sheet springs, etc. For example, in this embodiment, the elastic component is preferably a plurality of butterfly sheet springs, and the plurality of butterfly sheet springs are stacked in sequence to enhance the abutting force of the first elastic component 3 on the rod 22.

[0034] It should be noted that, due to its unique bowl-shaped structure, the butterfly spring can be configured in different ways to provide different resistance forces depending on the stacking arrangement of the individual butterfly springs. For example, multiple butterfly springs stacked in the same direction can withstand extremely high loads in a small space, making them suitable for applications requiring high load-bearing capacity and low deformation requirements. Alternatively, two butterfly springs stacked in opposite directions can significantly increase the deformation of the elastic component without increasing the load, providing a larger buffer stroke and effectively absorbing impacts and vibrations. Furthermore, combining multiple butterfly springs stacked in the same direction with two butterfly springs stacked in opposite directions allows for flexible adjustment of the load-bearing capacity and deformation of the elastic component by adjusting the number of these two stacking methods to meet the needs of various complex working conditions.

[0035] It is understood that the connection structure between the rod 22 and the shaft 21 described above includes, but is not limited to, plug-in, screw-in, welding, adhesive, tenon and mortise joints, etc. For example, in this embodiment, the rod 22 and the shaft 21 are connected by plug-in.

[0036] For details, please refer to Figure 1 One end of the rod 22 is provided with a sleeve part 221, and the sleeve part 221 is provided with a socket 2211. The rotating shaft 21 is inserted into the socket 2211 so that the rotating shaft 21 is connected to the rod 22.

[0037] Understandably, to avoid slippage between the pivot 21 and the rod 22, the sleeve 221 is interference-fitted with the pivot 21; or in some embodiments, the side wall of the pivot 21 is provided with a limiting part (not shown), and the inner side wall of the insertion hole 2211 is provided with a limiting groove (not shown). When the pivot 21 is inserted into the insertion hole 2211 of the sleeve 221, the limiting part and the limiting groove are engaged, thereby achieving a stable connection between the pivot 21 and the rod 22.

[0038] For further details, please refer to Figure 1 To facilitate the assembly of the rod 22, the rotating shaft 21 includes a first section 211 and a second section 212, which are connected. The diameter of the first section 211 is larger than that of the second section 212, forming an abutment platform 213 between them. The diameter of the first section 211 is larger than that of the insertion hole 2211. When the rod 22 is inserted into the rotating shaft 21, the sleeve 221 abuts against the abutment platform 213, which axially limits the rod 22, preventing excessive deviation in the insertion position and affecting subsequent assembly. Furthermore, the elastic component 3, after being sleeved on the first section 211, presses down on the rod 22, causing the rod 22 to abut against the abutment platform 213.

[0039] In some embodiments, please refer to Figure 1The rotating handle 1000 includes a gasket assembly 4, which includes a first gasket 41 and a second gasket 42. The first gasket 41 is disposed between the elastic component 3 and the rod 22 to avoid wear between the rod 22 and the elastic component 3, transferring the original wear contact surface between the rod 22 and the elastic component 3 to the rod 22 and the first gasket 41. After long-term use, only the first gasket 41 or the rod 22 needs to be replaced, reducing the maintenance cost of the rotating handle 1000. The second gasket 42 is disposed between the side of the rod 22 away from the elastic component 3 and the inner wall of the housing assembly 1, transferring the original wear contact surface between the rod 22 and the inner wall of the accommodating cavity 11 to the rod 22 and the second gasket 42. After long-term use, only the second gasket 42 or the rod 22 needs to be replaced, reducing the maintenance cost of the rotating handle 1000.

[0040] It should be noted that, in order to reduce the contact between the gasket assembly 4 and the rotating shaft 21 and to prevent the rotating shaft 21 from causing the gasket assembly 4 to rotate, in this embodiment, the first gasket 41 is provided with a first through hole 411 for the second section 212 of the rotating shaft 21 to pass through, and the second gasket 42 is provided with a second through hole 421 for the first section 211 of the rotating shaft 21 to pass through.

[0041] Furthermore, to extend the service life of the rotating handle 1000 and reduce the replacement frequency of the gasket assembly 4, the first gasket 41 and the second gasket 42 are selected from wear-resistant materials according to actual needs, including but not limited to: polymers, carbon fibers, alloys, etc. For example, in this embodiment, the material of the first gasket 41 is Teflon, and / or the material of the second gasket 42 is Teflon.

[0042] In some embodiments, to optimize the handling feel when the rod 22 rotates, a lubricating layer (not shown) is filled between the shim assembly 4 and the rod 22. Furthermore, to prevent the lubricating layer from affecting the frictional positioning effect on the rod 22, the viscosity of the lubricating layer needs to be maintained within a certain range, for example, 40 to 60. For example, in this embodiment, the viscosity of the lubricating layer is preferably 45.

[0043] For housing assembly 1 mentioned above, please refer to... Figure 1 The housing assembly 1 includes a first housing 1a and a second housing 1b. Both the first housing 1a and the second housing 1b are plate-shaped. The first housing 1a is provided with a first groove 1a1. One end of the rotating shaft 21 (i.e., the second segment 212 mentioned above) and the elastic component 3 are both accommodated in the first groove 1a1. The second housing 1b is provided with a second groove 1b1, and a rotating groove 12 is provided in the second housing 1b. The second groove 1b1 communicates with the rotating groove 12 and is used to accommodate the other end of the rotating shaft 21. The first housing 1a and the second housing 1b are connected so that the first groove 1a1 and the second groove 1b1 together form a receiving cavity 11.

[0044] In some embodiments, please refer to Figure 1 and Figure 3 The bottom of the second groove 1b1 is provided with a receiving groove 1b11, and the second gasket 42 is received in the receiving groove 1b11. Placing the second gasket 42 in the receiving groove 1b11 can further reduce the volume of the rotating handle 1000. In addition, the receiving groove 1b11 limits the second gasket 42 to prevent the second gasket 42 from shaking and generating noise, which would affect the actual user experience.

[0045] Understandably, in order to facilitate the rotation of the rotating shaft 21, the housing assembly 1 needs to be provided with structures for supporting both ends of the rotating shaft 21, including but not limited to: rotating grooves, rotating holes, etc. For example, in this embodiment, a rotating hole structure is used.

[0046] Specifically, the housing is provided with a first rotating hole 1a2 and a second rotating hole 1b2, which are respectively connected to the receiving cavity 11. The first rotating hole 1a2 is located in the first housing 1a and at the bottom of the first groove 1a1; the second rotating hole 1b2 is located in the second housing 1b and is used to receive the other end of the rotating shaft 21, and is located at the bottom of the receiving groove 1b11. The arrangement of the first rotating hole 1a2 and the second rotating hole 1b2 can further reduce the thickness of the housing assembly 1, reduce the volume of the housing assembly 1, and facilitate the use of the rotating handle 1000 in a limited space.

[0047] It is understood that the connection between the first housing 1a and the second housing 1b may include, but is not limited to, screwing, snap-fitting, welding, etc. For example, in this embodiment, the first housing 1a and the second housing 1b are connected by screwing.

[0048] For details, please refer to Figure 1 The housing assembly 1 also includes a plurality of first screw connectors 1c; the first housing 1a is provided with a plurality of first through holes 1a3; the second housing 1b is provided with a plurality of first screw holes 1b3, with one first through hole 1a3 corresponding to one first screw hole 1b3; a first screw connector 1c passes through a first through hole 1a3 and is screwed into a first screw hole 1b3. The screw connection allows the housing assembly 1 to form a detachable connection, and the way the first screw connectors 1c connect the first housing 1a and the second housing 1b also ensures the structural strength of the entire rotating handle 1000.

[0049] For example, in this embodiment, there are three first screw connectors 1c, three first through holes 1a3, and three first screw holes 1b3. The three first through holes 1a3 are distributed around the first through hole 411, and the corresponding first screw holes 1b3 are distributed around the second through hole 421.

[0050] It is understood that the connection between the grip 23 and the rod 22 may include, but is not limited to, screw connection, snap connection, welding, integral molding, etc. For example, in this embodiment, the grip 23 and the rod 22 are connected by screw connection.

[0051] For details, please refer to Figure 4 and Figure 5 The rotating handle 1000 also includes a second screw connector 5; the grip 23 is provided with a insertion groove 231, and the other end of the rod 22 is inserted into the insertion groove 231; the side wall of the insertion groove 231 is provided with an internal thread (not shown in the figure), and the other end of the rod 22 away from the insertion groove 231 is provided with a retaining groove 222, and the external thread of the second screw connector 5 engages with the internal thread. Through the cooperation of the second screw connector 5, the insertion groove 231 and the retaining groove 222, a detachable connection between the grip 23 and the rod 22 is achieved, improving the utilization rate of the parts of the rod 22 and the grip 23. During maintenance and replacement, the parts can be replaced according to the damaged area, reducing maintenance costs. Furthermore, different grips 23 can be replaced according to the actual use scenario. Compared with the one-piece molded grip 23 and rod, this detachable screw connection method saves the mold opening cost of the rod 22 and the grip 23.

[0052] In this embodiment, the rotating handle 1000 includes a housing assembly 1, a rotating assembly 2, and an elastic assembly 3. The housing assembly 1 is provided with a receiving cavity 11 and a rotating groove 12, and the rotating groove 12 communicates with the receiving cavity 11. The rotating assembly 2 is rotatably disposed in the receiving cavity 11 and includes a rotating shaft 21 and a rod 22. The rotating shaft 21 is rotatably disposed in the receiving cavity 11, one end of the rod 22 is disposed on the rotating shaft 21, and the other end of the rod 22 extends out of the receiving cavity 11 from the rotating groove 12. The other end of the rod 22 is provided with a gripping part 23 for the user to hold. The elastic assembly 3 is placed between the rod 22 and the housing so that the side of the rod 22 away from the elastic assembly 3 presses against the inner wall of the receiving cavity 11. The elastic component 3 provides a continuous and stable abutment force to the rod 22, so that the rod 22 can always generate friction with the inner wall of the accommodating cavity 11 during rotation, thereby achieving friction positioning of the rod 22 and ensuring that the rod 22 will not wobble during movement, thus improving the user experience of the rotating handle 1000.

[0053] This utility model also provides an embodiment of a mechanical device, which includes the aforementioned rotating handle 1000. For details on the specific structure and function of the rotating handle 1000, please refer to the above embodiment, which will not be repeated here.
