Description

Technical Field

[0001] The invention relates to the field of daily necessities, and in particular to a jumping box. Background Art

[0002] Suitcases and shopping carts are very convenient nowadays, but when going up and down stairs or on uneven roads, they still need to be lifted up and carried by someone, which is very strenuous for the user, especially in airports, high-speed rail stations, subway stations, and houses without elevators. When carrying large and small suitcases, users are often exhausted. In addition, there are shopping carts, especially for the elderly, who buy most of the food. They can still pull the shopping carts on flat roads, but they have to carry them very strenuously on uneven roads.

[0003] A Chinese patent discloses a suitcase that can go up and down stairs, with the authorization announcement number CN201710863349.1. The patented technology can enable the front running wheels to encounter obstacles on the stairs when going up the stairs, causing the rotating disk of the running wheels to rotate. The rotation of the rotating disk drives the upper running wheels to rotate, so that the upper running wheels rotate to the upper floor of the stairs, thereby realizing the automatic climbing of the suitcase. The rotation of the rotating disk can be driven by a micromotor to reduce the labor intensity of personnel. However, the running wheels of the entire suitcase need to match the height of the steps. When the step height does not match the running wheels, the suitcase can only be lifted by manpower, which cannot achieve a good labor-saving effect. Summary of the invention

A handle 3 is provided on the upper surface of the top shell 30. A jumping device is installed on the rear shell 25, and the jumping device includes a receiving mechanism 7 installed at the bottom of the rear shell 25 and a jumping rod 8 slidably connected to the receiving mechanism 7, and the jumping rod 8 can contact the ground. The jumping rod 8 is made of elastic steel, and an elastic rubber pad 19 is fixedly connected to its bottom. By setting the jumping rod 8 made of elastic steel, the jumping rod 8 can support the ground. When pressed downward, the elastic rubber pad 19 and the jumping rod 8 will cause a reverse force, so it bounces upward. At this time, the pull plate 5 can be pulled upward to go up the stairs; the principle of hitting a ball, it bounces up with a hit, and it can go to the next step with a lift.

[0026] Specifically, the receiving mechanism 7 includes a housing 23 and a first limiting hole 21 and a second limiting hole 22 provided on the housing 23, wherein the second limiting hole 22 is located above the first limiting hole 21. A limiting rod 24 in a compressed state is provided between the bouncing rod 8 and the first limiting hole 21, wherein one end of the limiting rod 24 is fixedly connected to the bouncing rod 8, and the other end is clamped in the first limiting hole 21. The limiting rod 24 includes a clamping plate 26 clamped in the first limiting hole 21, wherein one end of the clamping plate 26 is provided with a downwardly inclined ramp 27, and a foot switch 20 is provided in the first limiting hole 21, and pressing the foot switch 20 can cause the clamping plate 26 to be disengaged from the first limiting hole 21 and slide into the second limiting hole 22. A limit plate 29 is sleeved on the bouncing rod 8, and the limit plate 29 abuts against the card plate 26. When the bouncing rod 8 needs to be used, the elastic rubber pad 19 is stepped on by the foot to drive the bouncing rod 8 to move downward, and the limit plate 29 moves downward with the bouncing rod 8, and drives the card plate 26 of the limit rod 24 to move from the inside of the second limit hole 22 to the first limit hole 21. At this time, the limit rod 24 is in a compressed state and locked in the first limit hole 21 (such as Figure 6 When the retraction is required, the foot switch 20 is pressed by the foot, thereby driving the foot switch 20 to squeeze the card plate 26 out of the first limit hole 21 and slide into the second limit hole 22, thereby driving the limit rod 24 to return to its original position, completing the retraction function of the bouncing rod 8 (as shown in FIG. Figure 5 described above).

When the brake function is needed when going down the stairs, the brake pad 4 is pressed upward by hand to compress the spring 15, thereby driving the connecting plate 16 to move upward, so that the steel wire 17 moves upward, thereby driving the slide plate 18 to move to the left, and driving the connecting rod 12 to move toward the rotating shaft 9, so that the brake pad 10 is close to the rotating shaft 9, thereby completing the braking, preventing the speed from being too fast when going down the stairs, and improving the safety performance.

[0030] When the jumping box of the present invention is in use, when going up the stairs, the elastic rubber pad 19 is stepped on by the foot to drive the jumping rod 8 to move downward, thereby driving the limiting rod 24 to move from the inside of the second limiting hole 22 to the first limiting hole 21. At this time, the limiting rod 24 is in a compressed state and locked in the first limiting hole 21. At this time, the jumping rod 8 contacts the ground. When pressed downward, the elastic rubber pad 19 and the jumping rod 8 will cause a reverse force, thereby bouncing upward. At this time, the stairs can be climbed by pulling the pull plate 5 upward. According to the principle of hitting a ball, it bounces up with one hit, and it reaches the next step with one lift. When it needs to be retracted, the foot switch 20 is pressed by the foot, thereby driving the foot switch 20 to squeeze the card plate 26 out of the first limiting hole 21 and slide into the second limiting hole 22, thereby driving the limiting rod 24 to return to its original position, completing the retraction function of the jumping rod 8.

[0031] When the brake function is needed when going down stairs, the brake pad 4 is pressed upward by hand, thereby driving the connecting plate 16 to move upward, and driving the wire rope 17 to move upward, and the wire rope 17 drives the slide plate 18 to move to the left, so that the connecting rod 12 moves toward the rotating shaft 9, thereby driving the brake pad 10 to be close to the rotating shaft 9, thereby completing the braking.

[0032] The jumping box of the present invention is provided with a jumping rod made of elastic steel material, and the jumping rod is in contact with the ground. When going upstairs, the elastic rubber pad and the jumping rod are pressed downward to generate a reverse force, and the person can lift the box up to the next step in a convenient manner, so that the person can climb the stairs conveniently and save physical strength. The three groups of rollers are provided to form a triangular structure to improve the stability. The baffle is provided to prevent the connecting frame from being separated from the rotating shaft. The brake mechanism is provided to prevent the person from going down the stairs at an excessively high speed, so as to improve the safety performance in use.
