Description

Technical Field

[0001] This utility model relates to the field of luggage, and in particular to a luggage with a backpack. Background Technology

[0002] When traveling abroad, most people carry a backpack in addition to their suitcases because they are inconvenient to handle. The backpack is usually carried on board to hold personal belongings. When going through customs or transferring flights, the suitcase usually needs to be checked in, while the backpack is carried on board.

[0003] In reality, users rarely take out items from their backpacks during short trips, but they still have to carry the backpack for extended periods. Suitcases can be dragged, but backpacks still need to be carried on one's back, which can cause shoulder muscle strain over long periods. Utility Model Content

[0004] To improve the convenience of backpack transportation, this application provides a suitcase with a backpack.

[0005] The technical solution of this application for a suitcase with a backpack is as follows:

[0006] A suitcase with a backpack includes a suitcase body and a backpack body, and also includes a length adjustment component and several assembly units. The backpack body includes a bag body and at least one set of shoulder strap assemblies disposed on the bag body. The shoulder strap assembly includes two mounting straps, which are detachably connected to the suitcase body via the assembly units. The length adjustment component is used to adjust the length of the mounting straps so that the backpack fits snugly against the suitcase after installation. The ends of the two mounting straps away from the bag body are detachably connected to each other to form shoulder straps.

[0007] By adopting the above technical solution, when it is not necessary to carry the bag, the user can install the backpack body on the suitcase body. At this time, the user can move the backpack along with the suitcase by pulling the suitcase, which can improve the convenience of backpack transportation. When it is necessary to carry the bag, the backpack body can be removed from the suitcase body, and then the two mounting straps can be spliced ​​together. At this time, the two mounting straps can be connected to form a shoulder strap for the user to carry on their shoulder.

[0008] Preferably, the assembly unit includes a buckle and a snap fastener, which are respectively disposed on the suitcase body and the mounting strap, and are interlocked with each other. The two mounting straps are respectively provided with buckles and snap fasteners.

[0009] Preferably, the two mounting straps each include a long strap and a short strap, the length of the long strap being greater than the length of the short strap, and the strap length adjusting member is used to adjust the length of the long strap.

[0010] By adopting the above technical solution, the length adjustment component only needs to adjust the length of one installation strap, reducing the number of operation steps and making it easier to install the backpack.

[0011] Preferably, two mounting straps are respectively disposed at the upper and lower ends of the back of the bag body. The suitcase body includes a first shell, a second shell that docks with the first shell and defines a compartment, and a pull rod assembly. The pull rod assembly is disposed on the second shell. The upper mounting strap is installed on the top surface of the first shell, and the lower mounting strap is installed on the outer surface of the first shell.

[0012] By adopting the above technical solution, the installation of the backpack will not affect the use of the suitcase.

[0013] Preferably, the strap adjustment assembly includes a fixing block fixedly disposed on the back of the bag body, and the fixing block has a through groove for a long strap to pass through, and one end of the long strap passes through the through groove and comes out from the outside of the fixing block.

[0014] By adopting the above technical solution, since the long strap only has two states—one is fixed to the suitcase, and the other is worn on the shoulder in conjunction with the short strap—the adjustment degree of the strap adjustment component is fixed, so users no longer need to spend time slowly adjusting it to the appropriate length, thus improving the convenience of use.

[0015] Preferably, the long strap is positioned above the short strap, and the opening of the bag body faces upward.

[0016] By adopting the above technical solution, when the backpack body is installed on the suitcase body, it is sometimes necessary to take out the items inside the backpack body. The backpack opening faces upward, and the user needs to take out or put in items from the backpack opening. Since the connection point between the long strap and the suitcase body is converted to the fixed block, it means that the part of the bag body above the fixed block is not completely restricted. Since the bag body is usually soft, the upper part of the bag body can deform relatively freely, making it convenient for the user to take out and put in items.

[0017] Preferably, there are two sets of shoulder strap assemblies, which are respectively arranged on the left and right sides of the back of the bag.

[0018] By adopting the above technical solution, the two sets of shoulder strap components can improve the stability of the backpack body when mounted on the suitcase body. At the same time, there are two shoulder straps for the user to carry. The backpack can distribute the load evenly on both shoulders, avoid excessive pressure on one shoulder, help maintain body balance, and improve comfort.

[0019] Preferably, the buckle includes a base, the base having a buckle groove for engaging with a buckle, and a deformation opening being formed through one side wall of the buckle groove.

[0020] By adopting the above technical solution, the opening of the deformation port can improve the deformation of the seat and facilitate the fastening between the fastener and the buckle.

[0021] Preferably, a groove is formed on the outer surface of the first housing to accommodate a fastener or a snap fastener.

[0022] By adopting the above technical solution, the suitcase body usually needs to be laid down when taking out items. The groove can prevent the buckle or latch from protruding from the suitcase, so that the suitcase can be laid down stably on the ground.

[0023] The main technical effects of this utility model are reflected in the following aspects:

[0024] 1. When it is not necessary to carry the bag, the user can attach the backpack body to the suitcase body. At this time, the user can move the backpack along with the suitcase by pulling the suitcase, which can improve the convenience of carrying the backpack. When it is necessary to carry the bag, the backpack body can be removed from the suitcase body, and then the two mounting straps can be spliced ​​together to form a shoulder strap for the user to carry on their shoulder.

[0025] 2. By setting up a shoulder strap adjustment component, this utility model can adjust the long strap to a fixed degree, since the long strap only has two states: one is fixed to the suitcase, and the other is worn on the shoulder in conjunction with the short strap. The user no longer needs to spend time slowly adjusting it to the appropriate length, thus improving the convenience of use. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0033] This application discloses a suitcase with a backpack.

[0034] Reference Figures 1-3 The suitcase with a backpack in this embodiment includes a suitcase body 1 and a backpack body 2, and also includes a length adjustment component 3 and several assembly units 4. The backpack body 2 includes a bag body 21 and two sets of shoulder strap assemblies 22 disposed on the bag body 21. The two sets of shoulder strap assemblies 22 are respectively disposed on the left and right sides of the back of the bag body 21.

[0035] Reference Figure 2 and Figure 4 The shoulder strap assembly 22 includes two mounting straps, which are detachably connected to the suitcase body 1 via the assembly unit 4. The strap length adjustment piece 3 is used to adjust the length of the mounting straps so that the backpack fits snugly against the suitcase after installation. The ends of the two mounting straps away from the bag body 21 are detachably connected to each other to form a shoulder strap.

[0036] Reference Figure 2 and Figure 4 When it is not necessary to carry the bag, the user can attach the backpack body 2 to the suitcase body 1. At this time, the user can move the backpack by pulling the suitcase, which can improve the convenience of carrying the backpack. When it is necessary to carry the bag, the backpack body 2 can be removed from the suitcase body 1, and then the two mounting straps can be spliced ​​together to form a shoulder strap for the user to carry on their shoulder.

[0037] Reference Figure 4 The two sets of shoulder strap components 22 can improve the stability of the backpack body 2 when mounted on the suitcase body 1. At the same time, there are two shoulder straps for the user to carry. The backpack can distribute the load evenly on both shoulders, avoid excessive pressure on one shoulder, help maintain body balance, and improve comfort.

[0038] Reference Figure 2 and Figure 4The assembly unit 4 includes a buckle 41 and a buckle 42. The buckle 41 and the buckle 42 are respectively set on the luggage body 1 and the mounting strap. The buckle 41 and the buckle 42 are fastened to each other. The two mounting straps are respectively equipped with buckles 41 and buckles 42.

[0039] Reference Figure 3 and Figure 4 The backpack has two mounting straps, a long strap 221 and a short strap 222. The long strap 221 is longer than the short strap 222. The strap length adjustment component 3 is used to adjust the length of the long strap 221. The strap length adjustment component 3 only needs to adjust the length of one mounting strap, reducing the number of steps and making the backpack easier to install.

[0040] Reference Figures 1-3 Two mounting straps are respectively installed at the top and bottom ends of the back of the bag body 21, with one end of each strap fixed to the back of the bag body 21. The suitcase body 1 includes a first shell 11, a second shell 12 that connects to the first shell 11 and defines a compartment, and a pull rod assembly 13. The pull rod assembly 13 is mounted on the second shell 12. Both the first shell 11 and the second shell 12 are equipped with wheels 14 at their bottoms. The pull rod assembly 13 is a commonly used telescopic pull rod for suitcases, which will not be described in detail here. The upper mounting strap is installed on the top surface of the first shell 11, and the lower mounting strap is installed on the bottom end of the outer surface of the first shell 11. The installation of the backpack will not affect the use of the suitcase.

[0041] Reference Figure 3 and Figure 4 The shoulder strap adjustment assembly includes two fixing blocks 31 fixedly mounted on the back of the bag body 21. Each fixing block 31 corresponds to one of the two long straps 221. The two fixing blocks 31 are fixedly mounted on the left and right sides of the back of the bag body 21. A through-slot 32 is provided on each fixing block 31 for the long straps 221 to pass through. One end of each long strap 221 passes through the through-slot 32 and then comes out from the outside of the fixing block 31. When the user carries the bag on both shoulders, in a normal, practical posture, the two fixing blocks 31 are unlikely to cause discomfort or pressure on the user.

[0042] Reference Figure 3 and Figure 4 Since the long strap 221 has only two states—one is fixed to the suitcase, and the other is worn on the shoulder in conjunction with the short strap 222—the aforementioned shoulder strap adjustment component has a fixed degree of adjustment for the long strap 221. Users no longer need to spend time slowly adjusting it to the appropriate length, which improves the convenience of use.

[0043] Reference Figure 1The long strap 221 is located above the short strap 222, and the opening of the bag body 21 faces upward. When the backpack body 2 is installed on the suitcase body 1, it is sometimes necessary to take out the items inside the backpack body 2. With the backpack opening facing upward, the user needs to take out or put in items from the backpack opening. Since the connection point between the long strap 221 and the suitcase body 1 is transferred to the fixing block 31, it means that the part of the bag body 21 above the fixing block 31 is not completely restricted. Since the bag body 21 is usually soft, the upper part of the bag body 21 can deform relatively freely, making it convenient for the user to take out and put in items.

[0044] Reference Figure 2 and Figure 5 The buckle 41 includes a seat 411, on which a buckle groove 412 is provided to engage with the buckle 42. A deformation opening 413 is provided through one side wall of the buckle groove 412. The deformation opening 413 can improve the deformation of the seat 411 and facilitate the fastening between the buckle 41 and the buckle 42.

[0045] Reference Figure 2 The outer surface of the first housing 11 has a recessed groove 111 for accommodating the buckle 41 or the latch 42. When taking out items, the suitcase body 1 usually needs to be laid down. The groove 111 prevents the buckle 41 or the latch 42 from protruding from the suitcase, allowing the suitcase to be laid down stably on the ground.

[0046] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
