[0015] Optionally, threads are arranged on the inner walls of the two sides of the rotating pipe, limiting sleeves are connected to the threads on the two sides of the rotating pipe, limiting plates are connected to the limiting sleeves in the circumferential direction, and the limiting plates abut against the fixed sleeves.

[0016] By adopting the technical scheme, the limiting plates are connected to the limiting sleeves in the circumferential direction and abut against the fixed sleeves, thereby playing a limiting and fixing role, so that the fixed sleeves are stably fixed to the two ends of the rotating pipe, thereby ensuring that the overall structure of the handle is stable and effectively reducing shaking, so that the user can drag the luggage more labor-saving and comfortably.

[0017] Optionally, the two ends of the rotating pipe abut against the limiting plates.

[0018] By adopting the technical scheme, the connection between the fixed sleeves, the rotating pipe, and the limiting sleeves is more close, thereby strengthening the overall strength of the structure and ensuring the stability of the handle operation.

[0019] Optionally, a handle pipe is arranged on the outer wall of the outer pipe, and the handle pipe is in abutment with the fixed sleeves on the two sides of the rotating pipe.

[0020] By adopting the technical scheme, the handle tube can completely wrap the whole outer tube, so that the limiting block and the limiting hole are completely shielded, thereby preventing the user from being scratched by the limiting block due to directly holding the appearance, improving the safety of use, and improving the appearance of the pull rod.

[0021] Optionally, a plurality of sliding grooves are formed in the outer wall of the outer tube in the axial direction, and a plurality of sliding blocks are connected to the inner wall of the handle tube and are in sliding connection with the sliding grooves.

[0022] By adopting the technical scheme, through cooperation of the sliding grooves and the sliding blocks, when the user rotates the handle tube, the force of rotating the handle tube can be effectively converted into the force of rotating the outer tube, so that slipping between the handle tube and the outer tube during rotation is prevented, thereby affecting unlocking of the pull rod and improving the stability during use; and during assembly, cooperation of the sliding grooves and the sliding blocks facilitates assembly, thereby effectively improving the assembly efficiency.

[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0033] This application discloses a rotary lever handle. (Refer to...) Figure 1 , Figure 2 The rotary lever handle includes a handle body 1 for gripping, and an outer tube 3 sleeved onto a rotating tube 2. Fixed sleeves 4 are provided at both ends of the rotating tube 2. A first connecting block 41 fixedly connected to the rotating tube 2, a second connecting block 42 abutting against the bottom of the first connecting block 41, and a cylindrical component 43 fixedly connected within the fixed sleeve 4 are provided inside the fixed sleeve 4. A control rod 44 passes through the cylindrical component 43. One end of the control rod 44 is inserted into the second connecting block 42, and the other end is used to control the locking mechanism of the lever. When the user grips the handle body 1 and rotates it, the rotating tube 2 rotates, causing the first connecting block 41 to rotate and the second connecting block 42 to press down. This presses down the control rod 44, thus unlocking and locking the lever. The locking mechanism of the lever is existing technology and will not be described in detail here.

[0034] Reference Figure 2 , Figure 3 A limiting block 21 is fixedly connected to the outer wall of the rotating tube 2. The outer tube 3 has a limiting hole 31 for the limiting block 21 to move, and the limiting hole 31 is arranged circumferentially along the outer tube 3. When the handle is rotated, the outer tube 3 rotates around its axis, causing the inner wall of the limiting hole 31 to contact the limiting block 21, thereby driving the rotating tube 2 to rotate, thus unlocking and locking the handle. During this process, the limiting block 21 needs to move a certain distance along the limiting hole 31 before it can drive the rotating tube 2 to rotate, so that the handle has a certain rotational redundancy when rotating. This prevents the handle from being accidentally triggered and thus unlocking, which would affect the user experience and ensure the stability of the handle during use.

[0035] Reference Figure 3, the cylindrical part 43 is provided with a limiting groove 431 for placing the second connecting block 42, the limiting groove 431 effectively limits the movement direction of the second connecting block 42, so that the second connecting block 42 can only move in the vertical direction, thereby stably pressing down the control rod 44, ensuring the stability of operation. The bottom of the second connecting block 42 is provided with a fixing groove 421 for placing one end of the control rod 44, so that the control rod 44 is not easy to shake when the second connecting block 42 is pressed down, thereby ensuring that the other end of the control rod 44 can be stably unlocked, thereby ensuring the stability of the handle operation.

[0036] With reference to Figure 3 , the outer side of the control rod 44 is sleeved with an elastic element 45, the elastic element 45 is a spring, one end of the spring is attached to the bottom wall of the second connecting block 42, and the other end is attached to the inner bottom wall of the limiting groove 431. When the handle is loosened after rotation, the second connecting block 42 will be upwardly supported by the spring, thereby driving the first connecting block 41 and the rotating pipe 2 to reset, thereby realizing the function of automatic reset. And the spring sleeved on the outer side of the control rod 44 provides a certain buffering capacity, so that the handle feels softer when rotating, thereby enhancing the stability when holding.

[0037] With reference to Figure 3 , the first connecting block 41 is provided with a first inclined surface 411 on the side close to the second connecting block 42, and the second connecting block 42 is provided with a second inclined surface 422 on the side close to the first connecting block 41, the second inclined surface 422 is opposite to the inclination angle of the first inclined surface 411 and is attached to each other. When the rotating pipe 2 rotates, the attachment between the first inclined surface 411 and the second inclined surface 422 can effectively guide the relative movement between the two connecting blocks, so that the process of rotating the rotating pipe 2 to drive the control rod 44 to press down is more smooth, reducing jamming and friction, improving the flexibility and comfort of use.

[0038] With reference to Figure 4 , Figure 5 , the inner walls of the rotating pipe 2 on both sides are provided with threads 22, the threads 22 on both sides of the rotating pipe 2 are connected with a limiting sleeve 23, the limiting sleeve 23 is connected with a limiting plate 231 in the circumferential direction, and the limiting plate 231 abuts against the fixed sleeve 4. The limiting plate 231 and the limiting sleeve 23 play the role of fixing and limiting, the fixed sleeve 4 is extruded by the limiting plate 231 and is stably fixed at both ends of the rotating pipe 2, ensuring the stability of the overall structure of the pull rod handle, effectively reducing the shaking and improving the user's experience.

[0039] With reference to Figure 1 , Figure 2 and Figure 5The outer wall of the outer pipe 3 is provided with a handle 5, and the two ends of the handle 5 are respectively attached to the fixed sleeve 4 on both sides of the rotating pipe 2. The handle 5 can completely wrap the outer pipe 3 so that the limiting block 21 and the limiting hole 31 are not directly in contact with the human body, thereby preventing the user from being scratched by the limiting block 21 due to directly holding the appearance, improving the safety of use, and also improving the appearance of the handle. A plurality of sliding grooves 32 are formed in the outer wall of the outer pipe 3 along the axial direction, and a plurality of sliding blocks 51 are connected to the inner wall of the handle 5, and the sliding blocks 51 are slidingly connected with the sliding grooves 32. When the handle 5 is rotated, the force of rotating the handle 5 can be effectively converted into the force of rotating the outer pipe 3, preventing slipping between the handle 5 and the outer pipe 3 during rotation, thereby affecting the unlocking of the pull rod, and improving the stability during use

[0040] The implementation principle of the rotating pull rod handle according to an embodiment of the present application is as follows: by rotating the handle, the outer pipe 3 rotates to make the limiting block 21 abut against the inner wall of the limiting hole 31, at this time the outer pipe 3 can drive the rotating pipe 2 to rotate, the first connecting block 41 drives the second connecting block 42 to press down, at this time the control rod 44 can be pressed down to realize the unlocking or locking of the pull rod.

[0041] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
