[0042] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Please refer to the following first. Figures 1 to 4 , Figure 1 This is a schematic diagram of an embodiment of the auxiliary luggage box for going up and down stairs according to the present invention, applied to a luggage box. Figure 2 This is a schematic diagram of another embodiment of the auxiliary luggage-going-up-and-down-stairs device of this utility model applied to a luggage. Figure 3 This is a schematic diagram of one embodiment of the device for assisting a suitcase in going up and down stairs according to the present invention; Figure 4 This is a schematic diagram of an embodiment of the auxiliary component of this utility model. The device for assisting the luggage to go up and down stairs includes two symmetrically arranged auxiliary components 1 and fastening strap components 2 for fixing the two auxiliary components 1 to the right-angled sides of the back panel 41 of the luggage.

[0044] like Figure 2 and Figure 3 As shown, in order to adapt to suitcases 4 of various sizes, a telescopic rod 3 can be connected between the two auxiliary components 1. By adjusting the length of the telescopic rod 3, the distance between the two auxiliary components 1 can be changed, allowing the two auxiliary components 1 to be fixed to suitcases 4 of different sizes. Those skilled in the art can adjust the number of the telescopic rods 3 according to actual conditions.

[0045] like Figure 4 As shown, the aforementioned auxiliary component 1 is L-shaped, specifically including a first molded plate 11 and a second molded plate 12 connected vertically. (As...) Figure 2 As shown, in the assembled state, the inner wall of the first plate 11 is joined to the side panel 42 of the suitcase, and the inner wall of the second plate 12 is joined to the back panel 41 of the suitcase 4.

[0046] Each auxiliary component 1 also includes a support plate 13, which can slide along the width of the side panel 42 of the suitcase when the suitcase 4 is being dragged on the road, thereby being stored inside the first molded plate 11. Next, in conjunction with... Figures 4 to 6 To explain, Figure 5 This is a cross-sectional view of one embodiment of the auxiliary component of this utility model; Figure 6 This is a schematic diagram of the structure of one embodiment of the support plate of this utility model. Figure 4 As shown, the first type of plate 11 has a groove 111 for accommodating the support plate 13. Figure 5 As shown, two first guide rails 112 are provided on the inner wall of the slide 111. The orientation of the first guide rails 112 is the same as the width direction of the side panel 42 of the suitcase.

[0047] like Figure 6As shown, two first guide rail grooves 131 are formed on the outer wall of the support plate 13. Please refer to the following... Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of a structure of an embodiment of the present invention where the support plate slides along the groove; Figure 8 This is a schematic diagram of another embodiment of the support plate of this utility model that slides along the groove. Figure 7 and Figure 8 As shown, in the assembled state, the first guide rail groove 131 and the first guide rail 112 are slidably engaged, allowing the support plate 13 to extend along the first guide rail 112 or be housed in the first molded plate 11. It should be noted that the first guide rail 112 can be disposed on the two inner walls of the slide groove 111, and correspondingly, the first guide rail groove 131 can be disposed on the two side walls of the support plate 13. Those skilled in the art can adjust these settings according to actual conditions.

[0048] In this way, by setting the first guide rail 112 and the first guide rail groove 131, the sliding direction of the support plate 13 can be constrained, and the friction can be reduced to improve the smoothness of sliding.

[0049] Please refer to the document again. Figure 4 A trapezoidal groove 113 is provided on the side of the aforementioned groove 111 that faces away from the second molded plate 12. Please refer again. Figure 6 Two trapezoidal blocks 133 are pivotally connected to both sides of the aforementioned support plate 13. The dimensions of these trapezoidal blocks 133 are adapted to the aforementioned trapezoidal groove 113. Figure 8 As shown, when the support plate 13 retracts into the slide groove 111, to prevent the support plate 13 from falling off, the two trapezoidal blocks 133 can rotate into the trapezoidal groove 113. The two trapezoidal blocks 133 can be connected by a hinge. In this way, the trapezoidal blocks 133 can be engaged in the trapezoidal groove 113, thereby preventing the support plate 13 from sliding relative to the first molded plate 11, thus fixing the support plate 13.

[0050] When dragging the suitcase 4 up the stairs, the trapezoidal block 133 can be disengaged from the trapezoidal groove 113, allowing the support plate 13 to extend. Then, it can slide along the second plate 12 toward the center of the back panel 41 of the suitcase.

[0051] Please refer to 9 and review again. Figure 4 and Figure 6 , Figure 9 This is a schematic diagram of one embodiment of the support plate of this utility model that slides along a trapezoidal guide rail. Figure 4 As shown, the bottom of the second type plate 12 is provided with two trapezoidal guide rails 121 and two second guide rails 122. Figure 6As shown, the top of the support plate 13 has two trapezoidal guide rail grooves 132 and two second guide rail grooves 134, and the bottom is provided with a wheel set 135. Figure 9 As shown, in the assembled state, the trapezoidal guide rail 121 and the trapezoidal guide rail groove 132 are slidably engaged, and the second guide rail 122 and the second guide rail groove 134 are slidably engaged, thereby enabling the support plate 13 to slide along the trapezoidal guide rail 121 toward the middle of the back panel 41 of the suitcase 4.

[0052] The upper bottom of the trapezoidal guide rail 121 is fixedly connected to the bottom of the second plate 12, so that after the trapezoidal guide rail 121 slides with the support plate 13, the support plate 13 can be prevented from falling off, thus improving the reliability and safety of the device. The second guide rail 122 and the second guide rail groove 134 can constrain the sliding direction of the support plate 13 and reduce friction to improve the smoothness of sliding.

[0053] Although the above description uses two trapezoidal guide rails 121 and a second guide rail 122 as an example, those skilled in the art can adjust the number of the trapezoidal guide rails 121 and the second guide rail 122 according to the actual situation, and such changes do not exceed the protection scope of this disclosure.

[0054] Furthermore, it can be on the left side of the second type plate 12 ( Figure 9 The locating pin is set in the direction of the middle and connected to the support plate 13, thereby fixing the support plate 13 and preventing the support plate 13 from sliding along the trapezoidal guide rail 121.

[0055] like Figure 4 and Figure 9 As shown, the second plate 12 has strip grooves 123 on both sides. When the support plate 13 slides along the trapezoidal guide rail 121, the two trapezoidal blocks 133 pass through the two strip grooves 123 in a one-to-one correspondence, thereby avoiding interference between the trapezoidal blocks 133 and the second plate 12.

[0056] Revisit Figures 1 to 3 The fastening strap assembly 2 includes a top strap 21, a side strap 22, and a bottom strap 23. The top strap 21 connects to the top of the two first-shaped plates 11 and wraps around the top of the suitcase 4. The side straps 22 connect to the sides of the two first-shaped plates 11 and wrap around the suitcase 4 along its thickness direction. Each of the two first-shaped plates 11 has a connecting plate 24 at its bottom for supporting the suitcase 4, and the bottom strap 23 connects to the two connecting plates 24 from the bottom of the suitcase 4. In this way, the two auxiliary assemblies 1 can be fixed to the suitcase 4. The top strap, side straps, and bottom strap can be fastening straps with adjustable length.

[0057] Please see Figure 1 and Figure 9Taking going upstairs as an example, since the wheel set 135 of the support plate 13 protrudes from the second type plate 12, the wheel set 135 contacts the stairs during the upstairs process, thus saving manpower and effectively preventing the back panel 41 of the suitcase from being scratched by contact with the stairs. The distance between this auxiliary component 1 and the wheels of the suitcase 4 can be adjusted so that after the wheel set 135 leaves the stairs, the wheels of the suitcase 4 contact the stairs, making the entire process of moving the suitcase 4 smoother.
