Detailed Implementation

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

This application discloses a folding handle for a suitcase, as shown in Figures 1 to 6. It includes a handle body 1 and two rotating handle bodies 2. The handle body 1 has a first inclined surface 10 formed at both ends, and the rotating handle body 2 has a second inclined surface 20 formed at its end. The second inclined surface 20 of the two rotating handle bodies 2 respectively fits into the two first inclined surface 10. The second inclined surface 20 and the first inclined surface 10 are hinged together by a shaft assembly, so that the rotating handle body 2 can rotate to a horizontal position or a vertical position. A limiting mechanism is provided in the handle body 1 or the rotating handle body 2, which is used to lock the relative position of the second inclined surface 20 and the first inclined surface 10.

Based on the mutual contact and rotational cooperation between the second inclined surface 20 and the first inclined surface 10, the first throttle body 2 can be rotated to a horizontal position to unfold, or rotated to a vertical position for easy storage and folding, making it convenient for users to control steering. At the same time, it saves space and makes the structure of the folding handle of this application more compact.

Regarding the preferred structure of the shaft assembly, in this embodiment, as shown in Figures 2, 3 and 5, the shaft assembly includes a rotating shaft 30 and a bearing 31. One of the rotating shaft 30 and the bearing 31 is disposed at the center of the second inclined surface 20, and the other is disposed at the center of the first inclined surface 10. The rotating shaft 30 passes through the bearing 31 and is rotatably engaged with the bearing 30.

Preferably, the rotating shaft 30 is fixed at the center of the second inclined portion 20, the bearing 31 is embedded at the center of the first inclined portion 10, the rotating shaft 30 passes through the bearing 31 and the two are rotatably engaged, and the first inclined portion 10 is provided with a fixing member for fixing the rotating shaft 30. The fixing member may be a screw or a stepped ring, buckle, or other structure at the end of the rotating shaft 30.

In order to ensure good rotational engagement between the handle body 1 and the rotating handle body 2, in this embodiment, the first inclined surface 10 is provided with an annular groove 101, and the second inclined surface 20 is provided with a convex ring 201 concentric with the rotating shaft 30. The convex ring 201 is located inside the annular groove 101 and the two are rotated together.

This embodiment limits the rotatable angle of the rotating handle 2. As shown in Figures 2 to 5, a circular boss 21 is formed at the center of the second inclined surface 20, and an arc-shaped clearance recess 22 is formed at the edge of the circular boss 21. A limiting block 11 is formed on the first inclined surface 10. The limiting block 11 is disposed within the arc-shaped clearance recess 22 and the two are slidably connected. When the rotating handle 2 rotates by a preset angle, the limiting block 11 abuts against the end of the arc-shaped clearance recess 22. In the above structure, the limiting block 11 is formed on the first inclined surface 10. Based on the sliding fit between the limiting block 11 and the arc-shaped clearance recess 22, the rotatable angle of the rotating handle 2 can be limited within the arc range of the arc-shaped clearance recess 22.

As a preferred embodiment, the first beveled portion 10 faces diagonally downwards from the handle body 1. Referring to Figure 6, based on the above structure, the two rotating handle bodies 2 can extend into a T-shape or fold into a U-shape relative to the handle body 1.

In order to provide elastic stress to the rotating handle 2 so that the rotating handle 2 can automatically rotate into place after the limiting mechanism is released, in this embodiment, a torsion spring 4 is connected between the second inclined part 20 and the first inclined part 10.

In a preferred embodiment, the rotating handle 2 includes a housing 23, and the second inclined portion 20 is fixed to the end of the housing 23.

Furthermore, the limiting mechanism is located inside the housing 23.

To achieve the locking and limiting functions, in this embodiment, the limiting mechanism is disposed within the rotating handle 2. The limiting mechanism includes a fixed base 50, a slider 51, a button 52, and a spring 53. The fixed base 50 is fixed within the housing 23 and has a sliding groove 54. The slider 51 is disposed within the sliding groove 54, and the two slide in a sliding manner. The spring 53 abuts against the rear end of the fixed base 50 and the slider 51. The button 52 is drivenly connected to the slider 51. When the button 52 is pressed, the button 52 drives the slider 51 to move backward along the sliding groove 54 and compresses the spring 53, causing the limiting post 57 to move backward and release the limiting lock. When the button 52 is released, the spring 53 drives the slider 51 to slide forward and reset, causing the limiting post 57 to return to the initial limiting lock position.

The button 52 is embedded in the housing 23 and the two are movablely engaged. One end of the button 52 located inside the housing 23 forms a wedge-shaped tongue 55. The slider 51 forms a wedge-shaped opening 56. The wedge-shaped tongue 55 passes through the fixed base 50 and abuts against the inner wall of the wedge-shaped opening 56. When the button 52 is pressed, the wedge-shaped tongue 55 drives the slider 51 to slide backward. The front end of the slider 51 forms a limiting post 57. The limiting post 57 passes through the through hole 24 on the second inclined surface 20 and the two are movablely engaged. The first inclined surface 10 is provided with two limiting holes 13, one above the other. When the rotating handle 2 is rotated upward or downward by a preset angle, the limiting post 57 is aligned and inserted into the corresponding limiting hole 13.

In the above structure, the slider 51 is driven to move backward by the button 52, so that the limiting post 57 exits from the limiting hole 13. At this time, the locking function of the rotating handle 2 is released, and the rotating handle 2 can be rotated. However, when the button 52 is not pressed, the spring 53 applies elastic force to the slider 51. When the rotating handle 2 rotates until the limiting post 57 is aligned with the limiting hole 13, the limiting post 57 automatically inserts into the limiting hole 13, thereby achieving the limiting and locking function.

This application also provides a suitcase, including the folding handle of any of the above-mentioned embodiments. The suitcase provided by this application adopts all the technical solutions of all the above-mentioned embodiments of the folding handle, and therefore has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments of the folding handle, which will not be described in detail here.

The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the nature and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.
