Description

Technical Field

[0001] This application relates to the technical field of luggage, and in particular to a small suitcase. Background Art

[0002] In recent years, with the acceleration of people's living rhythm and the diversification of travel modes, small suitcases, especially mini suitcases, have gradually become a popular choice for travel, business, and daily commuting due to their light weight, fashion, and practical features. These suitcases cleverly integrate modern design concepts to meet the needs of efficient travel. They not only have an exquisite appearance but also ensure sufficient storage space, providing great convenience for users.

[0003] In the related art, a small trolley suitcase includes a box body, a box cover arranged on the box body, and four universal wheels fixed to the bottom side of the box body. The opening of the box body is arranged on its own vertical outer side. The box cover is installed on the edge of the opening of the box body through a hinge and a zipper, and a telescopic and adjustable trolley structure is installed on the vertical side of the box body. In addition, an X-shaped fixing belt, an interlayer zipper bag, etc. are arranged inside the box body to facilitate the user to classify and fix items.

[0004] However, although such suitcases perform well in most scenarios, in specific environments such as rainy days, their design still has certain limitations. Although users can provide rain protection for themselves, rainwater may still quietly seep into the interior of the box body through the zipper gap at the connection between the box cover and the box body, posing a potential threat to the items inside the box. This seepage may not only cause the items to get damp but may also cause damage in severe cases, bringing unnecessary losses and inconveniences to users, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a small suitcase to solve the problem in the above-mentioned related art that rainwater may seep into the interior of the box body through potential paths such as zipper gaps on rainy days, posing a potential threat to the items inside the box.

[0006] The small suitcase provided by this application adopts the following technical solutions: A small suitcase, comprising a box body and a box cover. An installation opening is formed on the vertical side surface of the box body. The box cover is detachably installed on the outer edge of the installation opening. A plurality of rollers are provided on the bottom side of the box body. A telescopic pull rod is installed on the upper side surface of the box body. Two opposite support rods are hinged to the upper part of the box body. The two support rods are symmetrically located on both sides of the box cover and can be rotated, adjusted and fixed. A connecting plate is provided above the box body. The two ends of the connecting plate are respectively fixedly connected to the ends of the two support rods. A protective curtain and a tightening member for winding up the protective curtain are fixedly provided on the outer edge of the connecting plate. The protective curtain can be unfolded downward to protect the connection between the box cover and the box body. A first fastener for fixing the unfolded protective curtain is provided outside the box body.

[0007] By adopting the above technical solution, by providing a connecting plate above the box body and fixedly providing a protective curtain on the outer edge of the connecting plate, when it rains, the user can unfold the protective curtain and cover it on the zipper gap at the connection between the box cover and the box body, so as to effectively prevent rainwater from seeping into the box body through these potential paths. The tightening member is used to wind up the protective curtain to keep it tidy and orderly when not in use. The first fastener is used to fix the unfolded protective curtain to ensure that the protective curtain can firmly cover the connection between the box cover and the box body in windy and rainy weather.

[0008] Optionally, the first fastener includes a first sub-button fixedly provided on the protective curtain and a first mother-button fixedly provided outside the box body. The first sub-button and the first mother-button can be mutually clamped and fixed.

[0009] By adopting the above technical solution, the user only needs to align the first sub-button on the protective curtain with the first mother-button outside the box body and gently press it to achieve quick clamping and fixing. Similarly, when releasing, only a simple operation is needed to pull out the sub-button from the mother-button without additional tools or complex steps.

[0010] Optionally, support seats are fixedly provided on the opposite edges of the upper part of the box body. Locking screw holes are formed in the support seats. Locking through holes are formed at the ends of the support rods far away from the connecting plate. A locking bolt passing through the locking through hole and screwed into the locking screw hole is provided outside the box body.

[0011] By adopting the above technical solution, the user can quickly fix the support rod at the required angle by tightening the locking bolt. This quick-fixing method is not only simple to operate but also can ensure that the support rod always maintains a stable position during use.

[0012] Optionally, an elastic clamping member is provided on the outer side surface of the support rod. A plurality of positioning grooves for the elastic clamping member to snap into are formed around the locking screw hole on the support seat.

[0013] By adopting the above technical solution, the user only needs to gently push the elastic clamping member to disengage it from the current positioning groove, and then rotate the support rod to the desired angle. When the support rod reaches the target position, release the elastic clamping member, and it will automatically snap into the nearest positioning groove to complete the fixation. This design simplifies the adjustment process of the support rod and improves the operation efficiency.

[0014] Optionally, the locking bolt is a wing bolt.

[0015] By adopting the above technical solution, the head of the wing bolt has a unique design. Its wide wing-shaped head allows the user to directly and easily hold and rotate it by hand without having to search for tools everywhere. This design greatly improves the operation convenience, enabling the user to quickly get started when fixing or releasing the support rod, saving time and effort.

[0016] Optionally, two elastic straps are symmetrically and fixedly arranged along the vertical direction on the side of the box body away from the lid.

[0017] By adopting the above technical solution, when the road is rough, the user can retract the pull rod and release the protection of the elastic straps. At this time, the user can directly carry the suitcase on both shoulders. The elastic straps can distribute the weight to both shoulders or one shoulder, effectively reducing the burden on the arms and wrists and reducing the fatigue.

[0018] Optionally, an elastic pad is fixedly arranged on the side of the box body facing the elastic straps.

[0019] By adopting the above technical solution, the elastic pad can serve as a buffer layer, effectively reducing the pressure on the back when the user carries the suitcase on the back. When the user carries the suitcase for a long time, this buffering effect can reduce back fatigue and discomfort.

[0020] Optionally, the connecting plate can rotate towards the elastic straps to a horizontal state along with the support rod, and the protective curtain can be unfolded downward and cover the outside of the elastic straps in this state; a second fastener is arranged outside the box body, and the second fastener is used to fix the protective curtain covering the outside of the elastic straps.

[0021] By adopting the above technical solution, when the protective curtain is unfolded and covers the elastic straps, it can form an effective protective barrier to prevent external pollutants such as dust and rain from adhering to the elastic straps, making the appearance of the suitcase cleaner.

[0022] Optionally, the second fastener includes a second sub-button fixedly arranged on the protective curtain and a second mother-button fixedly arranged outside the box body.

[0023] By adopting the above technical solution, the second fastener is designed with a second male buckle and a second female buckle, making the fixing and releasing of the protective curtain very simple and fast. The user only needs to align and fasten the second male buckle with the second female buckle to fix the protective curtain, and when it needs to be released, just gently press the male buckle to untie it, without a complex operation process.

[0024] Optionally, limiting notches for the upper edge of the box body to be inserted are provided on opposite side surfaces of the connecting plate.

[0025] By adopting the above technical solution, the design of the limiting notches enables the connecting plate to be fixed more firmly above the box body. When the connecting plate is installed on the box body, the upper edge of the box body will be inserted into the limiting notches, thereby restricting the horizontal movement of the connecting plate. This fixing method is not only simple and effective, but also can ensure that the connecting plate will not fall off or shift due to external forces during use.

[0026] In summary, the present application includes the following beneficial technical effects: A connecting plate is provided above the box body, and a protective curtain is fixedly arranged on the outer edge of the connecting plate. When it rains, the user can unfold the protective curtain and cover the zipper gap at the connection between the box cover and the box body, thereby effectively preventing rainwater from seeping into the box body through these potential paths; the tightening member is used to wind up the protective curtain, facilitating keeping it tidy and orderly when not in use; the first fastener is used to fix the unfolded protective curtain to ensure that the protective curtain can firmly cover the connection between the box cover and the box body in windy and rainy weather.
