[0026] Please refer to Figures 1 to 6 , the present utility model provides a luggage case with an auxiliary opening function, including a first case shell 10, a second case shell 20 disposed opposite to the first case shell 10, a connecting member (not shown in the figure) connecting the first case shell 10 and the second case shell 20, a first connecting frame 30 installed on the first case shell 10, a second connecting frame 40 installed on the second case shell 20, a female buckle 60 installed on the first connecting frame 30, a male buckle 70 installed on the second connecting frame 40, a linkage assembly 80 installed on the second connecting frame 40 and connected to the male buckle 70, and a plurality of groups of auxiliary members 50 installed on the first connecting frame 30. The connecting member can be rotated and adjusted in position so that the first case shell 10 can be closed on the second case shell 20 or opened from the second case shell 20. When the first case shell 10 is closed on the second case shell 20, the first connecting frame 30 and the second connecting frame 40 are mutually attached, the female buckle 60 is buckled on the male buckle 70, and the auxiliary members 50 are in a contracted state. When the linkage assembly 80 drives the male buckle 70 to adjust the position so that the female buckle 60 is disengaged from the male buckle 70, the auxiliary members 50 will assist in pushing open the first case shell 10.
[0027] In this embodiment, both the first connecting frame 30 and the second connecting frame 40 are metal frames. In other embodiments, the first connecting frame 30 and the second connecting frame 40 can also be plastic frames.
[0028] The first connecting frame 30 is generally square in shape as a whole. A first mating surface 11 is provided at the bottom position of the first connecting frame 30. The first mating surface 11 is a flat surface. A convex rib 12 is provided on the first connecting frame 30 on the first mating surface 11. The convex rib 12 is distributed along the square shape of the first connecting frame 30. A plurality of fixing seats 13 are also provided on the first connecting frame 30, and the fixing seats 13 are used for installing the auxiliary members 50.
[0029] In this embodiment, the number of the fixing seats 13 is two, and the two fixing seats 13 are respectively provided at the positions of the front side frame edges on the two side frame edges of the first connecting frame 30. A first positioning groove 14 is provided on the top surface of the fixing seat 13. A second positioning groove 15 is provided in the middle of the bottom of the first positioning groove 14. The bottom of the second positioning groove 15 further penetrates downward to form a through hole 16.
[0030] Each of the auxiliary parts 50 includes a limit block 51, a power rod 52 opposite to the limit block 51, and a return spring 53 arranged between the power rod 52 and the limit block 51. Ears 511 are provided on both sides of the limit block 51. The power rod 52 includes a main rod body 521 and a limit head 522 connected to one end of the main rod body 521. The cross-section of the limit head 522 is larger than the main rod body 521. The power rod 52 is also provided with a slot 523. The slot 523 extends inward from the middle of the limit head 522 and extends into the interior of the main rod body 521.
[0031] During assembly, the main rod 521 of the booster rod 52 passes through the first positioning slot 14 and the second positioning slot 15 and extends from the through-hole 16. The limiting head 522 of the booster rod 52 is clamped at the inner opening of the through-hole 16. The limiting block 51 is disposed in the first positioning slot 14. The present invention further includes a plurality of fixing members, which pass through the ear portions 511 of the limiting block 51 and are mounted on the bottom of the first positioning slot 14. The fixing members limit the limiting block 51. One end of the return spring 53 extends into the clamping slot 523 of the booster rod 52 and abuts the booster rod 52. The other end of the return spring 53 abuts the limiting block 51.
[0032] The male buckle 70 is slidably mounted on the second connecting frame 40, and the linkage assembly 80 includes a base 81, an adjustment block 82 slidably mounted on the base 81, a linkage rod 83 connected to the adjustment block 82, and an adjustment spring 84 mounted on the base 81 and abutting against the adjustment block 82. The adjustment block 82 drives the male buckle 70 to shift horizontally through the linkage rod 83.
[0033] The second connecting frame 40 is generally square in shape. A second mating surface 41 is provided near the top of the second connecting frame 40 . The second mating surface 41 is flat. A groove 42 is provided on the second mating surface 41 of the second connecting frame 40 . The inner space of the groove 42 corresponds to the rib 12 .
[0034] In the initial state, the male buckle 70 is located on the moving path of the female buckle 60 when the first housing 10 is covered on the second housing 20. When the first housing 10 is pressed to cover the second housing 20, the female buckle 60 is pressed by the inclined guide surface on the male buckle 70 to shift backward, and the adjustment spring 84 elastically contracts until the buckle hole of the female buckle 60 is aligned with the male buckle 70. The adjustment spring 84 pushes the male buckle 70 to be locked in the buckle hole of the female buckle 60. The second mating surface 41 of the second connecting frame 40 is in contact with the first mating surface 11 of the first connecting frame 30, the rib 12 is locked in the groove 42, and the second mating surface 41 presses the auxiliary rod 52 extending from the through hole 16, causing the auxiliary rod 52 to avoid inward, and the return spring 53 elastically contracts.
[0035] When the adjusting block 82 is slid away from the female buckle 60, the adjusting spring 84 elastically contracts, the male buckle 70 detaches from the female buckle 60, and the return spring 53 pushes open the first connecting frame 30 and the first box shell 10 installed on the first connecting frame 30 through the power rod 52. The buckle hole of the female buckle 60 and the male buckle 70 are staggered, and a gap is formed between the first connecting frame 30 and the second connecting frame 40, which makes it convenient for the user to further flip up the first box shell 10 through the gap.
[0036] The beneficial effect of the suitcase with auxiliary opening function of the present invention is that: by arranging an auxiliary part 50 installed on the first connecting frame 30, the auxiliary part 50 includes a limit block 51, a power rod 52, and a return spring 53 arranged between the power rod 52 and the limit block 51, the power rod 52 extends from the first connecting frame 30, and when the first box shell 10 is pressed to cover the first box shell 10 on the second box shell 20, the second matching surface 41 squeezes the power rod 52 extending from the through hole 16, so that the power rod 52 avoids inward, and the return spring 53 elastically contracts. After the male buckle 70 is detached from the female buckle 60, the return spring 53 pushes the first connecting frame 30 open through the power rod 52 to form a gap between the first connecting frame 30 and the second connecting frame 40. The user can open the box shell with one hand operation, which effectively improves the convenience during use and has strong practicality.
[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0038] 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.
