[0003] Existing laptop bags are generally designed as handbags for carrying with one hand. However, carrying such bags while traveling on public transportation, such as subways and buses, can be inconvenient when the crowds are large, as one hand needs to hold the bag while the other hand needs to hold onto the armrest, making it difficult to maintain balance and freeing up both hands. Therefore, a new type of laptop bag is needed. Utility Model Content

[0006] Preferably, the fastener has an opening, and the limiting component includes a hook that is hinged to the bag body and can extend into the limiting opening, and a blocking part provided on the side of the hook near the bag body to prevent the fastener from disengaging. A torsion spring is provided at the hinge, and a limiting part for accommodating the fastener is provided on the side of the hook away from the blocking part.
[0007] Preferably, the top of the fastener is provided with a magnetic part, and the blocking part is filled with a magnetic block that is magnetically repelled by the magnetic part.
[0008] Preferably, the positioning component includes a knob that is threadedly connected to the guide member and can be rotated for positioning. The top of the knob is provided with a limiting head that can be opened. The knob can be screwed in to press against the fastener and block the fastener through the limiting head.
[0009] Preferably, the guide is provided with rollers that slide in contact with the shoulder strap.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model uses limiting and positioning components to limit the position of the shoulder strap, allowing it to be switched between a handheld laptop bag and a shoulder bag for different scenarios. The switching is quick and easy, ensuring convenient travel. When used as a shoulder bag, it frees up the hands and improves the applicability of the laptop bag. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0018] A laptop bag with an assembleable shoulder strap, such as Figure 1 As shown, the bag includes a body 1 and a shoulder strap 2. Both sides of the body 1 are provided with guides 3 to guide the shoulder strap 2 to move up and down. The guides 3 are provided with openings to accommodate the shoulder strap 2. The two ends of the shoulder strap 2 are provided with buckles 6. The bottom of the body 1 is provided with a limiting component 4 that can limit the position of the shoulder strap 2 by limiting the buckles 6. The guides 3 are provided with positioning components 5 that can cooperate with the buckles 6 to limit the position of the shoulder strap 2. The buckles 6 are provided with openings.
[0019] like Figure 1 and Figure 2 As shown, when used as a laptop bag, since the positioning component 5 includes a knob 10 that is threadedly connected to the guide 3 and can be rotated for positioning, and the top of the knob 10 is provided with a limiting head 11 that can pass through the opening, the buckles 6 at both ends of the shoulder strap 2 are brought close to the guide 3. First, the knob 10 is turned out so that the space between the knob 10 and the guide 3 can accommodate the buckle 6 to pass through. Then, the buckle 6 is passed through the limiting head 11 along the opening. Then, the knob 10 is turned in to press against the buckle 6 and the limiting head 11 blocks the buckle 6. This completes the assembly of the buckle 6 on the shoulder strap 2 and the guides 3 on both sides of the bag body 1, and it can then be used as a laptop bag.
[0020] like Figure 3 and Figure 4 As shown, when used as a shoulder bag or laptop bag, the limiting component 4 includes a hook 7 that is hinged to the bag body 1 and can extend into the limiting opening, and a blocking part 9 provided on the side of the hook 7 near the bag body 1 to prevent the buckle 6 from disengaging. A torsion spring is provided at the hinge. A limiting part 8 for accommodating the buckle 6 is provided on the side of the hook 7 away from the blocking part 9. First, turn the knob 10 out to release the knob 10 and the limiting head 11 from limiting the buckle 6. After releasing the limiting, pull the buckle 6 to move the shoulder strap 2 closer to the hook 7 at the bottom. Press the hook 7 to overcome the torsion spring action. After opening, push the buckle 6 into the limiting part 8 of the hook 7. Since the top of the buckle 6 is provided with a magnetic part, and the blocking part 9 contains a magnetic block that is magnetically repelled by the magnetic part, the buckle 6 will be driven to press against the limiting part 8 of the hook 7 under the magnetic repulsion of the magnetic part, preventing the hook 7 from loosening and falling out. After being released, the hook 7 will reset under the action of the torsion spring and limit the buckle 6. When you want to release the laptop bag and put it back into use, press the hook 7 to make it open to overcome the torsion spring and allow the buckle 6 to be released. Then you can pull out the buckle 6 and repeat the above steps.
[0021] In addition, the guide 3 is provided with a roller 12 that slides in contact with the shoulder strap 2. The roller 12 can assist the shoulder strap 2 to move smoothly and reduce wear on the shoulder strap 2 when switching.
[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
