Description

Technical Field

[0001] The utility model relates to a bag structure, in particular to a bag which is convenient for tapping and fixing. Background Art

[0002] A trolley case is a type of luggage that can be used to store personal belongings, providing great convenience when traveling. With the continuous advancement of technology, a variety of styles of trolley cases have appeared on the market. Most trolley cases consist of a first shell, a second shell, a zipper connecting the first and second shells, a pull rod mounted on the first shell, and wheels mounted on the first and second shells.

[0003] In addition to the first and second housings, the pull rod, and the rollers, a type of trolley case with a decorative strip has also appeared on the market. The decorative strip is decorated with the manufacturer's trademark or other types of decorative patterns for decorative and identification purposes. In addition, the decorative strip is a solid strip. During installation, screws pass through the inner side of the housing and screw into the decorative strip. During the screwing process, the decorative strip forms a screw hole with internal threads, and the external threads on the screw are fixed with the internal threads of the screw hole. Because the decorative strip is a solid strip, screwing in the screw is more laborious, which requires high installation workers, causing trouble for manufacturers. Utility Model Content

[0027] See also Figures 1 to 5 The present invention provides a bag that is easy to fix by tapping, comprising a first case 10, a second case 20, a connecting assembly 30 connecting the first case 10 and the second case 20, a pull rod (not shown) mounted on the second case 20, a roller 40 mounted on the bottom of the first case 10 and the second case 20, a decorative strip 50, and a plurality of fixing members 60. The decorative strip 50 is mounted on the first case 10 via the fixing members 60. In this embodiment, the connecting assembly 30 is a snap fastener, and the fixing member 60 is a locking screw. In other embodiments, the connecting assembly 30 may also be a zipper.

[0028] The first box shell 10 is arranged in a shell shape as a whole. The first box shell 10 includes a panel 11 and an outer surrounding plate 12 connected to the outer edge of the panel 11. The panel 11 and the outer surrounding plate 12 together form a receiving groove 13 with an opening. The outer surface of the first box shell 10 facing away from the receiving groove 13 is provided with a fixing groove 14. The fixing groove 14 extends in the horizontal direction, and the fixing groove 14 extends from the position of the panel 11 to the position of the outer surrounding plate 12 on both sides. In addition, the first box shell 10 is also provided with a plurality of through holes 15. The through holes 15 connect the fixing groove 14 and the receiving groove 13, and the through holes 15 are evenly spaced along the horizontal shape of the first box shell 10.

[0029] The decorative strip 50 is generally U-shaped, comprising a main section 51 and side sections 52 connected to the main section 51 at both ends. The main section 51 and the side sections 52 form an arc-shaped transition. A functional groove 53 is defined on the inner side of the decorative strip 50, extending along the entire length of the decorative strip 50. Opposing connecting surfaces 531 are formed within the groove 53. The decorative strip 50 is provided with internal thread groups 54 on each connecting surface 531. Each internal thread group 54 comprises a plurality of internal threads 541, extending along the entire length of the decorative strip 50. In this embodiment, the internal threads 541 have a triangular cross-section, with hollow grooves 542 formed on either side of the internal threads 541, the width of which gradually decreases inward. Furthermore, the outer diameter of the screw head 61 of the locking screw is smaller than the spacing between the two internal thread groups 54, while the outer diameter of the screw shaft 62 of the locking screw is larger than the spacing between the two internal thread groups 54.

[0030] During assembly, the decorative strip 50 is inserted into the receiving groove 13, with the main section 51 of the decorative strip 50 inserted into the receiving groove 13 at the panel 11, and the side section 52 of the decorative strip 50 inserted into the receiving groove 13 at the outer enclosure 12. The bottom of the functional groove 53 of the decorative strip 50 is arranged opposite the bottom of the receiving groove 13. The locking screw is then passed through the through-hole 15 of the first housing 10 and installed on the decorative strip 50. During installation, the screw head 61 of the locking screw is screwed in between the two internal thread groups 54, and the external threads on the screw shaft 62 of the locking screw are simultaneously tapped on the internal threads 541. The internal threads formed by the tapping on the internal threads 541 are fixed to the external threads of the locking screw, and the screw cap 63 of the locking screw is clamped on the inner side of the first housing 10.

[0031] The beneficial effect of the luggage that is easy to fix by tapping is that: by arranging the functional groove 53 on the decorative strip 50, the decorative strip 50 is provided with an internal thread group 54 on the two connecting surfaces 531 of the functional groove 53. When fixing the decorative strip 50, the screw head of the locking screw is screwed in from between the two internal thread groups 54, and the internal thread formed by tapping on the internal thread 541 is installed and fixed with the external thread of the locking screw. Since the hollow grooves 542 are formed on both sides of the internal thread 541, during the screwing-in process of the locking screw, it is only necessary to tap the internal thread 541, and there is no need to tap along the entire stroke of the locking screw, which effectively reduces the installation difficulty of the locking screw, improves the assembly efficiency, and has strong practicality.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
