[0014] The embodiments of the present invention are described in detail below. The embodiments are shown in the accompanying drawings, wherein the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions.
[0015] In the present invention, unless otherwise specified and limited, the terms "assembly", "connection" and "connection" should be understood in a broad sense, for example, it can be a locking connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0016] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, but cannot be understood as limiting the utility model.
[0017] The preferred embodiment provided by the utility model is as follows: Figure 1 to Figure 3As shown, a side-supported trolley case comprises a case body 1 and a support assembly 2; the support assembly 2 comprises a support protrusion 21, a spring 22 and a frame member 23, the frame member is installed on the side of the case body 1, the frame member 23 has a through cavity 24, and a guide groove 25 is provided in the through cavity 24; the spring 22 is placed in the through cavity 24, and the two ends of the spring 22 abut against the support protrusion 21 and the side of the case body 1 respectively;
[0018] A protrusion 26 extends from the side wall of the support protrusion 21, which is connected to the guide groove 25 through the protrusion 26 to connect the support protrusion 21 to the frame 23, and the protrusion 26 slides along the guide groove 25 to allow the support protrusion 21 to move in the through cavity 24, and the support protrusion 21 partially protrudes from the through cavity 24.
[0019] The supporting protrusion is an integrated structure. The supporting protrusion 21 includes a top 27 and a block 28. The spring 22 abuts against the block 28. The cross-sectional area of the top 27 is smaller than the cross-sectional area of the block 28, so that the top protrudes out of the through cavity. The top 27 is kept outside the frame 23, and the block 28 is kept inside the through cavity 24. One end of the frame 23 facing outward is bent to form a retaining edge 29, and the retaining edge 29 is movably connected to the block 28 to limit the supporting protrusion 21 from escaping from the through cavity 24.
[0020] Existing trolley cases generally only have wheels installed at the bottom of the case to support the whole case, and no support is provided on the side walls of the case. When the case is placed on its side, the ground is in direct contact with the case and the side of the case is easily contaminated by dirt on the ground. Therefore, it is necessary to add support to the side of the case to prevent the side of the case from being contaminated by dirt.
[0021] In order to solve the above problems, the present structure installs a support assembly on the side of the box, and the support assembly includes a support protrusion, a spring and a frame, wherein the frame is bonded to the side of the box, and the frame itself protrudes relative to the side of the box to form a first support body; further, the support protrusion is installed in the through cavity of the frame, and the top of the support protrusion is kept extending out of the frame, so that the top forms a second support body, and the first support body and the second support body are used to prevent the side of the box from directly contacting the ground when it is placed on its side. In order to reduce the impact of the box when it is placed on its side, a spring is placed in the through cavity, and the two ends of the spring abut against the support protrusion and the side of the box respectively. When the box is placed on its side, the spring will reduce the impact force of the box.
