Description

Technical Field

[0001] This utility model relates to the field of luggage handle technology, and in particular to a luggage handle with an adjustable drag angle. Background Technology

[0002] Bags and luggage are a general term for all kinds of bags used to carry things. Various kinds of bags and luggage have become indispensable accessories in people's lives. People demand that bag and luggage products not only be more practical, but also more decorative.

[0003] A search revealed an adjustable drag angle luggage handle disclosed in publication number "CN220403355U". The handle includes a handle frame with a symmetrical movable rod retractably connected to one end. A first connecting plate is fixedly connected to one end of the movable rod, and a second connecting plate is rotatably connected to the side of the first connecting plate via a pivot. A connecting rod is fixedly connected to one end of the second connecting plate. This adjustable drag angle luggage handle, through the first connecting plate on the movable rod and the second connecting plate on the connecting rod, allows for adjustment of the tilt angle between the connecting rod and the movable rod, thereby adjusting the drag angle of the luggage and greatly improving user comfort. Furthermore, the rotatable anti-slip sleeve, connecting rope, and elastic sleeve not only provide anti-slip and shock absorption but also prevent the handle from slipping off, thus avoiding damage to the contents of the luggage from falling.

[0004] This patent uses a positioning rod and an adjusting rod to adjust the dragging angle of the bag. However, this patent has limitations on the dragging angle of the bag, and it cannot be adjusted to any angle, which reduces the flexibility of the bag. Furthermore, when the weight inside the bag is large, the fixing mechanism of this patent cannot effectively fix the movable rod, causing the movable rod to detach from the bag when it is pulled, resulting in damage to the movable rod. Therefore, this needs to be improved. Utility Model Content

[0071] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a luggage handle with an adjustable drag angle.

[0072] An adjustable drag handle for a luggage includes a luggage body 1 and a support plate 2, the support plate 2 being fixedly connected to the luggage body 1; it also includes: multiple support blocks 3, which are evenly arranged on the support plate 2 and fixedly connected to the support plate 2; a support shaft 4, which is fixedly connected to the support blocks 3; support wheels 5, which are arranged on the support shaft 4 and rotatably connected to the support shaft 4; multiple rotating plates 6, which are arranged on the support plate 2 and fixedly connected to the support plate 2; a rotating mechanism, which is arranged on the rotating plates 6; and a spring mechanism, which is arranged on the luggage body 1.

[0073] Reference Figure 4 In a preferred embodiment, the rotating mechanism includes: a rotating frame 7, which is disposed on the rotating plate 6 and fixedly connected to the rotating plate 6; a rotating motor 8, which is fixedly connected to the rotating frame 7; a rotating shaft 9, which is detachably fixedly connected to the rotating motor 8; a rotating plate 10, which is fixedly connected to the rotating shaft 9; and a rotating component disposed on the rotating plate 10.

[0074] This configuration ensures that when the rotary motor 8 is running, it drives the rotary shaft 9, which is detachably and fixedly connected to the output end of the rotary motor 8, to rotate, causing the rotary plate 10, which is fixedly connected to the rotary shaft 9, to rotate, thus providing power for the rotating components.

[0075] Reference Figure 4 In a preferred embodiment, the rotating component includes: a first rotating shaft 11, disposed on the rotating plate 10 and fixedly connected to the rotating plate 10; a first rotating plate 12, rotatably connected to the first rotating shaft 11; a second rotating shaft 13, rotatably connected to the first rotating plate 12; a third rotating shaft 14, rotatably connected to the rotating plate 10; a tensioning plate 15, disposed on the third rotating shaft 14 and rotatably connected to the third rotating shaft 14; and a tensioning component, disposed on the third rotating shaft 14.

[0076] This configuration causes the tension plate 15 to rotate, which in turn drives the first rotating plate 12, which is rotatably connected to the first rotating shaft 11, to rotate, thereby driving the tensioning component to operate.

[0077] Reference Figure 4In a preferred embodiment, the tensioning component comprises: a first tensioning shaft 16, fixedly connected to the tensioning plate 15; a second tensioning shaft 17, fixedly connected to the rotating plate 6; a first tensioning block 18, rotatably connected to the first tensioning shaft 16; a second tensioning block 19, rotatably connected to the second tensioning shaft 17; a tension spring 20, one end of which is fixedly connected to the first tensioning block 18, and the other end of which is fixedly connected to the second tensioning block 19; and a telescopic assembly disposed on the rotating plate 6.

[0078] This configuration allows the tension spring 20, which is fixedly connected to the first tension block 18 and the second tension block 19, to contract and release elastic potential energy, thereby providing operating power for the telescopic assembly.

[0079] Reference Figure 4 In a preferred embodiment, the telescopic assembly includes: a first telescopic shaft 21, disposed on the rotating plate 6 and fixedly connected to the rotating plate 6; a telescopic plate 22, rotatably connected to the first telescopic shaft 21; a second telescopic shaft 23, rotatably connected to the telescopic plate 22; a first telescopic block 24, fixedly connected to the second telescopic shaft 23; a telescopic rod 25, fixedly connected to the first telescopic block 24; and a second telescopic block 26, fixedly connected to the stretching plate 15.

[0080] This configuration allows the first telescopic block 24 to drive the telescopic plate 22, which is rotatably connected to the second telescopic shaft 23, to rotate around the first telescopic shaft 21, thereby driving the telescopic rod 25 to rotate and thus achieving the rotation of the fixed rod 33.

[0081] Reference Figure 5 In a preferred embodiment, the elastic mechanism includes: an elastic frame 27, which is disposed on the housing 1 and fixedly connected to the housing 1; an elastic shaft 28, which is rotatably connected to the elastic frame 27; an elastic knob 29, which is fixedly connected to the elastic shaft 28; an elastic plate 30, which is rotatably connected to the elastic shaft 28; and a fixing component disposed on the elastic plate 30.

[0082] This configuration allows the rotation of the spring knob 29 to cause the spring shaft 28 to rotate on the spring frame 27, thereby driving the spring plate 30 to move closer to the fixed rod 33, which in turn drives the fixed component to move.

[0083] Reference Figure 4 and Figure 5 In a preferred embodiment, the fixing component includes: a plurality of fixing springs 31, which are evenly arranged on the elastic plate 30 and fixedly connected to the elastic plate 30; a fixing plate 32, which is fixedly connected to the fixing springs 31; a fixing rod 33, which is fixedly connected to the first telescopic block 24; a fixing groove 34, which is formed in the fixing rod 33; and a sliding component, which is disposed in the fixing groove 34.

[0084] This configuration causes the fixed spring 31 to compress, generating elastic potential energy. When the fixed rod 33 is pulled, the fixed plate 32 causes the fixed spring 31 to stretch, causing the fixed spring 31 to release its elastic potential energy, thereby reducing the tension on the fixed rod 33, thus achieving the goal of fixing the fixed rod 33 and reducing the tension.

[0085] Reference Figure 4 In a preferred embodiment, the sliding assembly includes: a sliding rod 35 disposed in a fixed groove 34 and slidably connected to the fixed groove 34; a sliding block 36 disposed on the sliding rod 35 and fixedly connected to the sliding rod 35; and a handle 37 fixedly connected to the sliding block 36.

[0086] With this configuration, by pulling the handle 37 which is fixedly connected to the sliding block 36, the sliding rod 35 which is fixedly connected to the sliding block 36 will slide in the fixed groove 34, thereby extending the length of the fixed rod 33.

[0087] Working principle: When the angle of the fixed rod 33 needs to be adjusted, the rotary motor 8 is started, which drives the rotary shaft 9, which is detachably fixedly connected to the output end of the rotary motor 8, to rotate. This causes the rotary plate 10, which is fixedly connected to the rotary shaft 9, to rotate, thereby causing the tension plate 15 to rotate. This causes the first rotary plate 12, which is rotatably connected to the first rotary shaft 11, to rotate. This causes the tension spring 20, which is fixedly connected to the first tension block 18 and the second tension block 19, to contract and release elastic potential energy. This causes the first telescopic block 24 to drive the telescopic plate 22, which is rotatably connected to the second telescopic shaft 23, to rotate around the first telescopic shaft 21, thereby causing the telescopic rod 25 to rotate.

[0088] Before pulling the fixed rod 33, first rotate the elastic knob 29 to make the elastic shaft 28 rotate on the elastic frame 27, thereby driving the elastic plate 30 to move closer to the fixed rod 33, thereby compressing the fixed spring 31 and generating elastic potential energy. When the fixed rod 33 is pulled, the fixed plate 32 drives the fixed spring 31 to stretch, causing the fixed spring 31 to release elastic potential energy, thereby reducing the tension on the fixed rod 33.

[0089] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
