[0002] The frame of a suitcase is mainly used for sealing the openings of the upper and lower sections, securing the zipper, and reinforcing the rigidity of the opening. The applicant previously disclosed a zipper mounting structure for a rolling suitcase in a utility model patent with authorization announcement number CN221729942U. This patent describes it as "...including a frame, a zipper, and a fixing strip; one side of the frame has a zipper connecting groove for connecting the zipper, and the other side has a suitcase connecting groove for connecting the suitcase body...the suitcase body is inserted into the connecting groove and fixed...". When fixing the suitcase body to the frame, glue is usually applied to the wall of the connecting groove or the opening wall of the suitcase to firmly bond the body to the frame. However, the walls of the connecting groove are generally flat, and when the suitcase is inserted, the glue is squeezed and overflows along the groove wall. Although the glue overflowing onto the inside of the suitcase can be covered by the lining after drying and does not affect the appearance, the glue overflowing onto the outside of the suitcase is exposed after drying without any covering, affecting the appearance of the suitcase. Therefore, it is necessary to improve the frame of the suitcase to prevent glue from overflowing and to protect the appearance of the suitcase, which is the problem to be solved in this case. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model discloses a luggage frame with a locking protrusion.

[0009] The clamping ports of the clamping strip include a first clamping port, a second clamping port and a third clamping port. The first clamping port is an outer clamping port. The first clamping port, the second clamping port and the third clamping port are all provided with openings that communicate with the outside.

[0010] The first clamping opening is a flat groove, and the card protrusion is placed on the inner side of the outer clamping piece and at the opening of the first clamping opening.

[0011] The second and third clamping ports are both cavities with a square cross-section and an opening communicating with the outside on one side of the cavity.

[0012] The first clamping opening, the second clamping opening, and the third clamping opening all extend along the length of the clamping strip.

[0013] The first clamping opening is used to insert the opening of the upper or lower body of the suitcase into the clamping strip, which seals the opening. The second clamping opening is used to secure the zipper between the upper and lower bodies of the suitcase. The third clamping opening is used to secure the zipper of the removable lining inside the suitcase.

[0014] As described above, the advantages of the luggage frame with a locking protrusion provided by this utility model are as follows: The inner wall of the outer clamping piece of the frame, used for fixing and sealing the luggage opening, has a locking protrusion protruding into the outer clamping opening. Firstly, the locking protrusion engages tightly with the grooves on the openings of the upper and lower sections of the luggage, preventing glue from overflowing from the outside of the luggage during the bonding process and avoiding damage to the luggage's appearance. Secondly, the locking protrusion on the frame engages with the grooves on the openings of the upper and lower sections of the luggage, making the frame less prone to detachment and improving the connection strength between the frame and the upper and lower sections of the luggage. This utility model, by improving the luggage frame, maintains its overall aesthetics and extends its service life. This utility model has a reasonable design, simple structure, low cost, and is easy to promote. Attached Figure Description
