Description

A limiting mechanism, a folding handle and a suitcase

[0001] This disclosure is based on and claims priority to Chinese Patent Application No. 202421722766.6, filed on July 20, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of luggage technology, specifically a limiting mechanism, a folding handle, and a luggage. Background Technology

[0003] The pull handle of a suitcase is a component that makes it easy to push and pull the suitcase. To make it easier to grip, a handle is set at the top of the pull handle. Existing suitcase handles are fixed U-shaped or T-shaped structures. During use, due to the limitation of the handle shape, people with large or small hands may find it inconvenient to grip the suitcase, which in turn affects the user's ability to push and pull the suitcase normally.

[0004] In addition, the limiting structure of traditional folding handles usually adopts a buckle-type locking mechanism, which requires the cooperation of both hands (one hand to hold the handle and the other hand to unlock), making the operation cumbersome. This is especially true for products such as luggage folding handles, where ease of operation is a high requirement. Traditional limiting mechanisms are particularly limited, and the buckle-type locking mechanism has a complex structure, which increases manufacturing costs and also leads to a higher failure rate, affecting the user experience. Summary of the Invention

[0005] In view of the shortcomings of the prior art, this application provides a limiting mechanism, a folding handle, and a suitcase.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution.

[0025] The present application will now be described in more detail with reference to the accompanying drawings and embodiments.

[0026] 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 connected by a hinge through a shaft assembly. A limiting mechanism is provided in the handle body 1 or the rotating handle body 2 to lock the relative position of the second inclined surface 20 and the first inclined surface 10. In the above structure, the handle body 1 is fixed to the upper end of the pull rod 6, the two first inclined surfaces 10 are respectively in contact with the two second inclined surfaces 20, and by setting the shaft assembly, the two rotating handle bodies 2 can rotate relative to the handle body 1. In particular, when the rotating handle body 2 rotates upward or downward by a preset angle, the limiting mechanism limits the rotating handle body 2. Compared with the prior art, this application is not only convenient to extend and fold, but also suitable for various hand shapes, and better meets the application needs.

[0027] 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. The rotating shaft 30 is fixed at the center of the second inclined portion 20, and 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. A fixing member for fixing the rotating shaft 30 is provided in the first inclined portion 10. The fixing member can be a screw or a stepped ring, buckle, or other structure at the end of the rotating shaft 30.

[0028] 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.

[0029] 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 inclination angle of the first beveled portion 10 is 45° relative to the horizontal plane. Due to the mutual contact and rotational engagement between the second beveled portion 20 and the first beveled portion 20, the rotating handle 2 can be rotated to a horizontal position to unfold, allowing the two rotating handles 2 to extend into a T-shape relative to the handle body 1. Alternatively, they can be rotated to a vertical position, allowing the two rotating handles 2 to fold into a U-shape relative to the handle body 1 for easy folding and storage. This facilitates user control and steering, while also saving space, making the folding handle structure more compact.

[0030] 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, 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 rotatably engaged. A torsion spring 4 is provided in the annular groove 101, and the two ends of the torsion spring 4 are respectively engaged with the first inclined surface 10 and the second inclined surface 20.

[0031] 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.

[0032] Furthermore, the limiting mechanism is located inside the housing 23.

[0033] To achieve locking and limiting functions, in this embodiment, the limiting mechanism includes a fixed base 50, a slider 51, a button 52, and a spring 53. The fixed base 50 is fixedly disposed within the housing 23, and a groove 54 is provided on the fixed base 50. The slider 51 is disposed within the groove 54, and the two slide in a sliding cooperation. The spring 53 abuts against the rear end of the fixed base 50 and the slider 51. The button 52 is embedded in the housing 23, and the two move in cooperation. One end of the button 52 located within the housing 23 is shaped like a... The slider 51 has a wedge-shaped tongue 55 and 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 10 and the two are movably engaged. The first inclined surface 10 has two limiting holes 13, which are symmetrically arranged on both sides of the annular groove 101. When the rotating handle 2 is rotated upward or downward by a preset angle, the limiting post 57 aligns and inserts into the corresponding limiting hole 13.

[0034] 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.

[0035] This application also provides a suitcase including any of the above-mentioned folding handles. The suitcase provided by this application adopts all the technical solutions of all the above-mentioned embodiments of the suitcase 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.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, or improvements made within the technical scope of this application should be included within the scope of protection of this application.
