[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0023] A carry-on / back bag according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 3 As shown, a carry-and-back dual-purpose bag according to an embodiment of the present invention may include a backpack body 1, a hand strap 2, a retractable shoulder strap 3 and two sets of fixing devices 4, wherein the hand strap 2 is arranged on the top of the backpack body 1, and the retractable shoulder strap 3 is arranged on one side of the backpack body 1, and the two sets of fixing devices 4 include a first fixing component 41 and a second fixing component 42, wherein the first fixing component 41 is arranged at the lower end of one side of the backpack body 1, and the second fixing component 42 is arranged at the upper end of the other side of the backpack body 1, and the retractable shoulder strap 3 is respectively engaged with the first fixing component 41 and the second fixing component 42.

[0025] As will be appreciated, the handle strap 2 is located on the top of the backpack body 1, allowing the user to lift the backpack by hand when not carrying it. The retractable shoulder strap 3 is located on one side of the backpack body 1 and can be adjusted in length based on the user's height and comfort level. One end of the shoulder strap is provided with a buckle that mates with the fixing device 4, while the other end is free and can be adjusted and secured with a retractable buckle 32.

[0026] The first fixing component 41 is located at the lower end of one side of the backpack body 1, and is used to fix the lower end of the retractable shoulder strap 3 in the carrying mode; the second fixing component 42 is located at the upper end of the other side of the backpack body 1, and is used to fix the retractable shoulder strap 3 after being wound in the hand-carrying mode.

[0027] Carrying mode: The user inserts one end of the retractable shoulder strap 3 into the first fixing component 41, adjusts the length of the shoulder strap to a suitable carrying position, and uses the retractable buckle 32 to tidy up and fix the excess part, and then the backpack can be carried like an ordinary schoolbag.

[0028] Hand-carry mode: The user first fully extends the retractable shoulder strap 3, then pulls it around the lower end of the backpack body 1 and upwards to the second fixing assembly 42, where it snaps into place. Now that the shoulder strap is wrapped around the backpack body 1, the backpack can be hand-carried by simply holding the hand strap 2. Because the shoulder strap is secured to the second fixing assembly 42 at the upper end, the risk of tripping due to the excessive length of the shoulder strap while walking is effectively avoided.

[0029] In one embodiment of the present invention, Figure 2 As shown, the retractable shoulder strap 3 may include two shoulder straps 31, two retractable buckles 32 and two snap rings 33, wherein one end of the two shoulder straps 31 is fixedly connected to the upper end of one side of the backpack body 1, the two retractable buckles 32 are movably connected to the two shoulder straps 31, and the two snap rings 33 are connected to the two retractable buckles 32. The length of the two shoulder straps 31 is sufficient to surround the lower end of the backpack body 1 to the second fixing component 42.

[0030] It is understood that the retractable buckle 32 is a key component of the retractable shoulder strap 3, used to adjust the length of the shoulder strap. The two retractable buckles 32 are movably connected to the two shoulder straps 31, respectively. Users can adjust the length of the shoulder strap by pulling or releasing the retractable buckles 32 to accommodate different heights or comfort requirements.

[0031] The snap rings 33 connect the retractable shoulder straps 3 to the fixing device 4. The two snap rings 33 are connected to the two retractable buckles 32, respectively. To carry the backpack, the user snaps the snap rings 33 into the first fixing assembly 41. To carry the backpack, the user wraps the shoulder straps around the backpack body 1, tightens them, and then snaps the snap rings 33 into the second fixing assembly 42.

[0032] In one embodiment of the present invention, Figure 2-Figure 3As shown, the first fixing component 41 may include two first fixing sleeves 411, wherein the two first fixing sleeves 411 are arranged at the lower end of one side of the backpack body 1, and the two first fixing sleeves 411 are respectively clamped with the two clamping rings 33, and the second fixing component 42 may include two second fixing sleeves 421, wherein the two second fixing sleeves 421 are arranged at the upper end of the other side of the backpack body 1, and the two second fixing sleeves 421 are respectively clamped with the two clamping rings 33.

[0033] It is understood that the two first fixing sleeves 411 are provided at the lower end of one side of the backpack body 1 for engaging with the two snap rings 33. When the backpack is in the carrying mode, the user can snap the snap ring 33 of the shoulder strap into the first fixing sleeve 411 to secure the lower end of the shoulder strap.

[0034] Two second fixing sleeves 421 are provided on the other upper end of the backpack body 1 and are also used to engage with the two snap rings 33. When the backpack needs to be converted into a hand-held mode, the user can wrap the shoulder strap around the lower end of the backpack body 1 and then snap the snap ring 33 into the second fixing sleeves 421.

[0035] Working principle and usage process:

[0036] 1. Carrying Mode

[0037] Step 1: Insert one end of the retractable shoulder strap 3 into the first fixing sleeve 411 of the first fixing assembly 41 through the snap ring 33 .

[0038] Step 2: Adjust the length of the shoulder strap 31 by retracting the buckle 32 according to the user's height and comfort level.

[0039] Step 3: Use the retractable buckle 32 to fix the excess part to ensure that the strap does not shake or affect its use.

[0040] Step 4: Place the backpack body 1 on your back and use the shoulder straps 31 to support the weight of the backpack, and then you can carry it like an ordinary backpack.

[0041] 2. Portable Mode

[0042] Step 1: Fully unfold the retractable shoulder strap 3 to ensure that the shoulder strap is long enough to pass around the lower end of the backpack body 1 to the second fixing component 42 .

[0043] Step 2: Pull the shoulder strap 31 around the lower end of the backpack body 1 and pull it upward to the second fixing component 42.

[0044] Step 3: Insert the shoulder strap 31 into the second fixing sleeve 421 of the second fixing assembly 42 through the snap ring 33 to ensure that the shoulder strap is wrapped around the backpack body 1 .

[0045] Step 4: Carry the shoulder strap 2 to carry the backpack. Since the shoulder strap is fixed to the second fixing component 42 at the upper end, the risk of tripping due to the shoulder strap being too long when walking is effectively avoided.

[0046] In summary, the dual-purpose bag of the embodiment of the utility model realizes the dual functions of a backpack and a handbag, and meets the usage needs in different scenarios. In the hand-carrying mode, the shoulder strap is designed to wrap around the bag body, which effectively avoids the risk of tripping due to the shoulder strap being too long when walking. The shoulder strap length is adjustable, the mode conversion is quick, and the user experience is friendly. It is suitable for students, office workers, travelers and other groups, and is suitable for daily commuting, travel and other occasions.
