[0029] The utility model is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-4 As shown, a frame structure includes a connecting frame 1 installed on a trolley case, the connecting frame 1 is provided with a mounting bar 11 for mounting a canvas and capable of being deformed under force, the mounting bar 11 is arranged around an inner wall of the connecting frame 1, and the connecting frame 1 is further provided with a mounting structure 10 for fixing the mounting bar 11;

[0031] The mounting structure 10 includes a plurality of mounting blocks spaced apart along the length direction of the mounting strip 11 ; the mounting blocks are formed with engaging grooves 14 for the mounting strip 11 to be embedded, and the openings of the engaging grooves 14 of two adjacent mounting blocks face opposite directions.

[0032] The function of the canvas is to cover items and prevent them from falling when the suitcase is opened. When the canvas is torn or damaged, since the mounting strip 11 is deformable, force can be applied to the mounting strip 11 to deform it, and the mounting strip 11 can be removed from the fitting groove 14 of the mounting block. After replacing the canvas, the mounting strip 11 can be installed back into the mounting block of the mounting structure 10 to increase the service life of the suitcase.

[0033] Specifically, the mounting block is divided into a first mounting block 12 and a second mounting block 13, wherein the fitting groove 14 of the first mounting block 12 opens downward, and the fitting groove 14 of the second mounting block 13 opens upward. With the above-mentioned design, the installed mounting strip 11 will not move up and down, and can be installed in the center, thereby increasing the installation stability of the canvas and the mounting block.

[0034] Preferably, the mounting strip 11 is formed by processing of metal material, and may also be formed by processing of plastic material.

[0035] At least one of the second mounting blocks 13 is formed with a first connection hole 15 , and the first connection hole 15 can be used to connect with the suitcase, so that the connection frame 1 is fixedly installed in the suitcase.

[0036] The connecting frame 1 is installed with a connecting block 20 connected to the trolley case. The connecting frame 1 is formed with a connecting groove 21. One end of the connecting block 20 extends outward and is inserted into the connecting groove 21. One end of the connecting block 20 is connected to the trolley case, and the other end is inserted into the connecting groove 21 of the connecting frame 1, thereby realizing the connection and fixation between the connecting frame 1 and the trolley case and improving the installation stability of the connecting frame 1.

[0037] At least one of the second mounting blocks 13 is formed with a locking groove 22 connected to the connecting groove 21, and the part of the connecting block 20 inserted into the connecting groove 21 is formed with a locking block 23 engaged with the locking groove 22; after the other end of the connecting block 20 is inserted into the connecting groove 21 of the connecting frame 1, the locking block 23 of the connecting block 20 is just locked into the locking groove 22 of the second mounting block 13, and the connecting block 20 can be connected to the connecting frame 1 without using bolts, thereby realizing a screw-free connection between the connecting frame 1 and the trolley case.

[0038] A trolley case comprises a frame structure and a pair of boxes 2, wherein a connecting frame 1 is installed at the opening of the boxes 2.

[0039] The box body 2 is formed with a second connecting hole 16 coaxially aligned with the first connecting hole 15. When the connecting frame 1 is connected to the box body 2, the first connecting hole 15 and the second connecting hole 16 are coaxially aligned. At this time, bolts can be inserted to connect the connecting frame 1 to the box body 2, further increasing the connection stability between the connecting frame 1 and the box body 2.

[0040] The connecting frame 1 is also equipped with a handle structure 24, which includes a handle block 25, and the handle block 25 is equipped with a rubber strip 26 that can be stretched and deformed; since the bearing capacity of the box body 2 is weak, the handle structure 24 is connected to the connecting frame 1. When the trolley case is lifted, it is connected to the connecting block 20 through the handle block 25, which can reduce the probability of damage and rupture.

[0041] The handle block 25 is formed with an embedded block 27, and the connecting frame 1 is formed with an embedded groove 28 for inserting the embedded block 27, and one or more of the second mounting blocks 13 is formed with a third connecting hole 17, and the connecting frame 1 and the embedded block 27 are respectively formed with a fourth connecting hole 18 coaxially aligned with the third connecting hole 17. The handle block 25 is inserted into the embedded groove 28 of the connecting frame 1 through the embedded block 27, so that the third connecting hole 17 and the fourth connecting hole 18 are coaxially aligned, and then bolts can be inserted to connect the connecting frame 1 and the embedded block 27 to achieve a fixed connection, thereby increasing the bearing capacity of the handle structure 24.

[0042] Furthermore, fixed blocks 29 are vertically formed at both ends of the handle block 25, the rubber strip 26 is installed between the two fixed blocks 29, and the box body 2 is formed with a handle groove 30 for installing the fixed block 29. The handle block 25 is connected to the handle groove 30, which further improves the connection stability between the handle structure 24 and the box body 2, and the stability is better when lifting.

[0043] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0044] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
