[0002] A suitcase, also known as a travel case or trolley case, is a type of luggage used to carry items when traveling. It is typically used to store clothing, personal care items, and souvenirs needed for travel. Early suitcases were made of wood or other heavy materials. With the rise of air travel, suitcases have become more lightweight, made of hard plastic or fabric. Most models also have built-in wheels for easy pulling. Since 2010, suitcases with four wheels have also appeared. These allow for 360-degree rotation and can be easily pushed on flat ground.

[0003] A suitcase consists of two openable compartments connected by a frame. Conventional luggage cases use rivets to secure the frame and compartments. This method requires precise rivet placement to ensure structural stability, making assembly cumbersome and causing the rivets to protrude from the outside of the compartments. This compromises the overall appearance of the suitcase, compromising its overall shape. Therefore, improvements to existing luggage structures are necessary. Utility Model Content

[0028] Please refer to Figures 1 to 5 As shown, it shows the specific structure of the preferred embodiment of the present utility model, which includes two box components 10 spliced ​​together.

[0029] Each box assembly 10 includes a box body 11 and a frame 12. The box body 11 defines a receiving cavity 101 with an open end. The frame 12 is disposed on the inner sidewall of the receiving cavity 101. The frame 12 is annular and has a groove 102 formed inwardly toward the sidewall of the box body 11, which fits the inner sidewall of the receiving cavity. The groove 102 is used to accommodate adhesive, thereby bonding and fixing the frame 12 and the box body 11 together. The inner sidewall of the frame 12 defines a through hole 103 that connects to the groove 102, allowing the adhesive to be fed into the groove 102 through the through hole 103, replacing the existing rivet fixing structure. The frames 12 of the two box assemblies 10 are spliced ​​and installed together, so that the receiving cavities 101 of the two boxes 11 together form a receiving cavity 104.

[0030] In this embodiment, the frame 12 extends outward from the opening of the accommodating cavity 101. A positioning groove 105 is provided on the outer end surface of the frame 12 in one box assembly 10, and a positioning portion 121 is provided on the outer end surface of the frame 12 in the other box assembly 10 to cooperate with the positioning groove 105. The two box assemblies 10 are positioned and installed together by the positioning portion 121 cooperating with the positioning groove 105. After positioning, the two box assemblies need to be connected together using a zipper structure to facilitate the opening process of the suitcase. The frame 12 includes an integrally formed connecting portion 122 and a splicing portion 123. The groove 102 is located on the connecting portion 122. The connecting portion 122 extends outward toward one side of the box body 11 to form a limiting portion 124. The limiting portion 124 is against the outer wall of the opening of the accommodating cavity 101. When the frame 12 is installed, the upper and lower positions of the frame 12 on the box body 11 are limited by the limiting portion 124, thereby further facilitating its assembly process; the splicing portion 123 extends outward from the corresponding accommodating cavity 101, and the positioning groove 105 and the positioning portion 121 are both formed on the corresponding splicing portion 123.

[0031] The frame 12 includes two parallel short sides 125 and two parallel long sides 126. Each short side 125 is provided with a through hole 103 that connects to the groove 102, allowing glue injection from both sides simultaneously and ensuring uniform glue injection into the groove 102. Multiple through holes 103 are arranged at intervals on each short side 125. The arrangement direction of the through holes 103 is the same as the extension direction of the short side 125. The provision of through holes 103 effectively increases the speed of glue injection, preventing premature solidification of the glue due to slow injection speed, which would affect the bonding effect. In this embodiment, the number of through holes 103 on each short side 125 is three. Similarly, the number of through holes 103 can also be set to another number based on the actual size of the suitcase, without limitation. The frame 12 is made of aluminum alloy.

[0032] The design focus of the present invention is that a groove is formed inwardly toward the side wall of the box body, which fits the inner side wall of the accommodating cavity, and a through hole is opened in the inner side wall of the frame to connect with the groove. When the frame and the box body are assembled, the adhesive colloid can be fed into the groove through the through hole, and the frame and the box body are bonded together by the fit between the groove and the box body. There is no need to use rivets for fixation, and there is no need to consider the problem of rivet position accuracy. The assembly process is more convenient. At the same time, no rivets will protrude from the outer side wall of the box body, making the overall integrity of the suitcase better and the appearance more beautiful, effectively improving the user experience.

[0033] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
