Description

Technical Field

[0001] The utility model belongs to the technical field of trolley cases, in particular to a stable trolley case. Background Art

[0002] A trolley case is a suitcase with a trolley and wheels. It is widely used because of its convenience. At the same time, trolley cases are also divided into single-tube trolleys and double-tube trolleys because of the trolley on the case. The tube of the trolley is also divided into square tubes and round tubes, which are convenient for dragging while walking, greatly reducing the burden. Trolley cases can be carried by hand or dragged. The wheels of the trolley cases we usually use are basically located at the bottom of the case, but modern people have designed a new form of trolley case, which is designed into a cylindrical shape, and the wheels are completely wrapped outside the case. This roller design allows this trolley case to better adapt to different terrains, such as directly pulling the case to go up and down stairs easily.

[0003] When most existing suitcases are in use, the internal space is generally set as an integral fixed space, which makes it impossible to adjust the internal space of the suitcase. As a result, when the suitcase is used with fewer items, the items cannot be pressed against each other, which may cause the items to collide with the inner wall of the suitcase during the movement of the suitcase, thereby causing damage to the items. Therefore, a stable suitcase is proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5As shown, the utility model is a stable trolley case, comprising a lower case 1, a pull rod 11 is slidably connected to the back of the lower case 1, an upper case 2 is hingedly connected to one side of the lower case 1, the lower case 1 corresponds to the upper case 2, a zipper is installed on the opposite sides of the lower case 1 and the upper case 2, moving wheels are movably installed on both sides of the lower surface of the lower case 1 and the upper case 2, a protective cloth 12 is hingedly connected to one inner wall of the lower case 1 and the upper case 2, a placement bag is fixedly connected to the surface of the two protective cloths 12 respectively correspond to the lower bag 1 and the upper bag 2. The surface of the upper bag 2 is fixedly connected with a transparent waterproof cover 13. The transparent waterproof cover 13 is made of PMMA material. Through the setting of the transparent waterproof cover 13, during the flushing process of the upper bag 2, the water body is blocked from directly flushing the printed fabric and fading, which has a sealing effect and makes the upper bag 2 resistant to water washing and flushing. The transparent waterproof cover 13 corresponds to the upper bag 2. The interiors of the upper bag 2 and the lower bag 1 are fixedly connected with a hollow plate 3. The two inner walls of the hollow plate 3 are A threaded rod 4 is rotatably connected through a bearing seat, and a carrying plate 20 is fixedly connected inside the hollow plate 3. The opposite sides of each two corresponding threaded rods 4 are rotatably connected to the two sides of the carrying plate 20 through the bearing seat respectively. The surfaces of the two threaded rods 4 are threadedly connected with sliding blocks 5. A sliding groove 6 is provided on one side of the hollow plate 3. The sliding block 5 is slidably connected to the inside of the sliding groove 6. One side of the surface of the two threaded rods 4 is connected to a rotating rod 7 through a belt transmission. The surfaces of the two rotating rods 7 are fixedly connected with knobs 8. A through groove 9 is provided on the surface of the hollow plate 3. A fixed plate 10 is fixedly connected inside the through groove 9. When placing items, the knob 8 is rotated according to the size of the items to make the rotating rod 7 rotate on the carrying plate 20, so that the threaded rod 4 rotates synchronously through the setting of the belt, so that the sliding block 5 slides inside the lower bag 1 through the sliding groove 6 to adjust the placement space inside the lower bag 1. The two ends of the two rotating rods 7 are rotatably connected to the hollow plate 3 and the corresponding fixed plate 10 through the bearing seat respectively.

[0028] The sliding block 5 is slidably connected to the interior of the upper bag 2 and the lower bag 1 through the sliding groove 6. The interior of the lower bag 1 and the upper bag 2 is equipped with a clamping mechanism near the hollow plate 3. The clamping mechanism includes movable grooves 16 respectively opened in the interior of the lower bag 1 and the upper bag 2. The number of movable grooves 16 is eight, and the eight movable grooves 16 are equally divided into two groups. The two groups of movable grooves 16 are respectively opened on the inner walls of the lower bag 1 and the upper bag 2. A clamping spring 17 is fixedly connected to the interior of each movable groove 16. One end of each clamping spring 17 is fixedly connected to a connecting plate 18. Each connecting plate 18 is slidably connected to the interior of the corresponding movable groove 16. Through the setting of the clamping mechanism, when placing larger items, the items push the clamping plate 19 to move, so that the connecting plate 18 slides in the interior of the movable groove 16 and compresses the clamping spring 17. Therefore, the elastic force of the clamping spring 17 makes the clamping plate 19 clamp the items, so that the placement of the items is more stable. One side of each corresponding connecting plate 18 is commonly fixedly connected with a snap-in plate 19, and the four snap-in plates 19 are respectively slidably connected to the inside of the lower bag 1 and the upper bag 2, and the snap-in plates 19 are slidably connected to the corresponding hollow plates 3. The back of the lower bag 1 is fixedly connected with a power supply assembly near the pulling rod 11, and the lower surfaces of the lower bag 1 and the upper bag 2 are commonly installed with a stabilizing mechanism, which includes four electric push rods 14 that are respectively fixedly connected to both sides of the lower surfaces of the lower bag 1 and the upper bag 2 and electrically connected to the power supply assembly through wires, and the output ends of every two corresponding electric push rods 14 are commonly fixedly connected with a stabilizing plate 15, and the two stabilizing plates 15 correspond to each other. Through the setting of the stabilizing mechanism, the trolley case slides through the moving wheels. When it is not sliding, the electric push rod 14 is started, so that its output end drives the stabilizing plate 15 to move downward, so that the stabilizing plate 15 fits against the ground, so that the moving wheels cannot rotate, thereby making the trolley case more stable when it is not moving, and the stabilizing plate 15 corresponds to the moving wheels.

[0029] Specifically, when the stable trolley case is in use: when placing items, according to the size of the items, the knob 8 is turned to make the rotating rod 7 rotate on the carrying plate 20, so that the threaded rod 4 is synchronously rotated through the setting of the belt, so that the sliding block 5 slides inside the lower bag 1 through the sliding groove 6, and the placement space inside the lower bag 1 is adjusted, so that the placement space is more suitable for the items, so that when the trolley case is used with fewer items, the sliding block 5 presses against the items, so that when the trolley case is moved, the items will not collide with the inner wall of the trolley case, and at the same time, through the setting of the clamping mechanism, when placing larger items, the items push the clamping plate 19 to move, so that the connecting plate 18 slides inside the movable groove 16, compressing the clamping spring 17, so that the clamping plate 19 clamps the items through the elastic force of the clamping spring 17, so that the placement of the items is more stable;

[0030] By setting the transparent waterproof cover 13, during the flushing process of the upper bag 2, the water is prevented from directly flushing the printed fabric and fading, which has a sealing effect and makes the upper bag 2 resistant to water washing. At the same time, by setting the stabilizing mechanism, the trolley case slides through the moving wheels. When it does not slide, the electric push rod 14 is started, and its output end drives the stabilizing plate 15 to move downward, so that the stabilizing plate 15 is in contact with the ground, and the moving wheels cannot rotate, so that the trolley case is more stable when it is not moving.
