Description

Technical Field

[0001] The utility model belongs to the technical field of luggage boxes, and more specifically relates to a riding luggage box with a liftable seat. Background Art

[0002] Luggage, also known as travel suitcases or trolley cases, is a common item used by people when going out. It is used to store things they need, such as clothes and daily necessities. Existing luggage has a low level of intelligence and mainly relies on manpower to pull or push the luggage to move. However, when there are many or heavy items in the luggage, it takes a lot of effort, which affects the travel experience. Cycling luggage has gradually appeared on the market. It can be used by riding, but the seat adjustment method is mostly simple flipping, which is less comfortable and not ergonomic.

[0003] For example, a height-adjustable pull rod structure and a suitcase using the pull rod structure disclosed in patent application No. 202121132869.3, the pull rod structure includes a fixed mounting tube, a cylindrical pull rod is installed in the mounting tube, an elastic pin and an elastic pressing block are provided on the pull rod, and a plurality of positioning holes are arranged at intervals along the length direction of the pull rod. A limit plate is provided at the upper end of the mounting tube, a rectangular channel is provided on the limit plate, and arc grooves are provided on two opposite sides of the rectangular channel for the outer peripheral surface of the pull rod to match and install. At least two pairs of anti-rotation surfaces are provided at intervals along the length direction of the pull rod, and the ends of the arc grooves form anti-rotation parts. When the elastic pin cooperates with the corresponding positioning hole, the corresponding anti-rotation surface on the pull rod stops and cooperates with the anti-rotation part on the limiting plate. The pull rod is an integral rod with high strength. When pulled out to different lengths, it is positioned and matched by the elastic pin and the positioning hole, and at the same time, it relies on the anti-rotation surface on the pull rod and the anti-rotation part on the limiting plate to stop the rotation, so the force strength is greater and it is not easy to be damaged.

[0004] Although the above-mentioned height-adjustable pull rod structure and the suitcase using the pull rod structure have greater force resistance and are not easily damaged, the seat adjustment of this riding suitcase is uncomfortable and not ergonomic. Utility Model Content

When pressing the switch 1601, the switch 1601 drives the hook 1617 to slide to the left of the sliding groove 1628, and the upper end of the hook 1617 is separated from the locking block 1621; because the reset torsion spring 1202 is in a deformed state, it always provides a rotational force to the lower section 1201 of the connecting rod. When there is no external force interference, the reset torsion spring 1202 will drive the connecting rod during the reset process. The lower section 1201 rotates. Since the lower section 1201 of the connecting rod is fixedly connected to the upper section 1204 of the connecting rod through the pin 1205, and the upper section 1204 of the connecting rod is rotatably connected to the box body 10, when the upper section 1204 of the connecting rod rotates upward with the lower section 1201 of the connecting rod, the box body 10 is translated and lifted, and then the lower section 1302 of the connecting rod also rotates with the box body 10. When the lower section 1302 of the connecting rod rotates, the brake pad 1304 The second lower section 1302 of the connecting rod is intermittently rotated relative to the second box body 11, which slows down the rotation speed of the second lower section 1302 of the connecting rod, so that the box body 10 is lifted steadily and slowly during the rotation relative to the second box body 11; when the side surface of the second lower section 1302 of the connecting rod abuts against the second box body 11, the reset torsion spring 1202 completes the reset and no longer provides rotational force; at this time, according to the height of the user, the latch 1306 and the pin shaft 1205 are pulled out to raise the height of the box body 10, and then the latch 1306 and the pin shaft 1205 are inserted into the corresponding holes to complete the adjustment of the height of the box body 10, and at the same time, the brake pad 1304 and the ratchet 1303 are used to lock the second lower section 1302 of the connecting rod when the box body 10 moves downward to prevent the box body 10 from tilting forward;

[0040] When it is necessary to pull, the button 1614 is pressed, and the button 1614 drives the push block 1613 to press the downward button 1627. When the downward button 1627 is pressed, the slider 4 1625 is driven to press the downward button 1627. Since the slider 3 1624 is provided with an inclined surface with a high left end and a low right end, the slider 3 1624 is pressed and slides toward the inner side of the pull rod 1 1615, and then the pull rod 1 1615 can be pulled out, and then the pull rod 2 1616 can be pulled out. During the process of pulling out, the slider 1622 on the steering block 1608 will be stuck in the second socket 1634 on the lower side of the fixed tube 1611, and the pull rod can be pulled at this time. When it is necessary to retract, since the slider 1622 is provided with an inclined surface, the pull rod 1616 can be directly pressed downward into the lower side of the sleeve 1605. The locking of the slider 1624 depends on pressing the button 1614 to drive the push block 1613 to press the push button 1627 downward, and the pull rod 1615 can be pulled out. When riding, the switch 1602 is pressed, the switch 1602 drives the push rod 1603 to press the slider 1604, the slider 1604 moves downward, and the slider 1622 on the lower side of the fixed tube 1611 is pressed into the inner side of the sleeve 1605, and then the slider 1622 pops out from the socket 1634 near the outer side of the box 11, and is clamped in the socket 1634 near the outer side of the box 11; the pull rod 1615 , the second pull rod 1616 is pulled out at this time and can be rotated to control the direction of travel. At this time, the pull rod 1615 and the second pull rod 1616 are elastically clamped and kept stable by the spring clip 1403. The second pull rod 1616 abuts against the steering gear 19. The pull rod 1615 can be rotated by rotating the operating table 1632, thereby driving the second pull rod 1616 to rotate. The arc surface of the second pull rod 1616 abuts against the steering gear 19 to cause the deviation to control the steering amplitude;

[0041] When it is necessary to reset the box body 10, restore the connecting rod 12 and the connecting rod 2 13 to their original lengths, then pull the insert block 1307 out of the lower section 1302 of the connecting rod 2 for a distance so that the brake pad 1304 does not contact the spring 1305, then use the legs or directly use the hands to push the box body 10 to move forward and downward, re-compress the reset torsion spring 1202, and the connecting rod 12 is now stored in the storage bin 1612, press the switch 1601, and lock the hook 1617 in the locking block 1621; push the insert block 1307 into the lower section 1302 of the connecting rod 2, so that the brake pad 1304 contacts the spring 1305 again, press the button 1614 and the switch 2 1602 in turn, and retract the pull rod 2 1616 and the pull rod 1 1615 to the inner side of the sleeve 1605.

[0042] Specific embodiment 2: Please refer to Fig.11, obtuse-angled stoppers 20 are fixedly arranged on both sides of the second box body 11; two pairs of crank arms 21 are arranged between the first box body 10 and the second box body 11; the first box body 10 and the second box body 11 are rotatably connected by the crank arms 21; the difference from the first embodiment is that the crank arms 21 are used to replace the first connecting rod 12 and the second connecting rod 13, the structure is simple, the processing cost is reduced, and at the same time, the two crank arms 21 on the same side can visually form a wavy curve when contracted, which increases the visual beauty;

[0043] Specific embodiment three: Please refer to Fig. 9 , the second shaft 1203 is set as a damping shaft; the difference from the first embodiment is that the blocking sense of the second shaft 1203 is utilized to slow down the resetting speed of the resetting torsion spring 1202, so that the box body 10 can be lifted more smoothly.

[0044] Specific embodiment 4: Please refer to Figure 1 The fixing frame 14 is a latch lock; the difference from the first embodiment is that the latch lock is a common automatic lock in the market with a simple structure. The spring block of the latch lock is opened by the second pull rod 1616, and the spring block originally abutting against the second pull rod 1616 is used to abut against the second pull rod 1616, which can also play a role in stabilizing the second pull rod 1616, making it more convenient to use.
