Description

Technical Field

[0001] This utility model relates to the technical field of hand-push transport vehicles, and in particular to an airport handcart that is resistant to being kicked. Background Technology

[0002] Large transportation hubs such as airports and train stations are widely equipped with luggage trolleys, which typically include a frame, a platform for placing luggage, a handrail, and multiple wheels. They are designed to make it easier for passengers to transport their personal luggage.

[0003] However, in actual use, existing handcart designs generally have inherent flaws. Because the rear structure of its storage platform overlaps vertically with the path of the person pushing it, when the person takes a large stride or walks quickly, their toes or calves are very likely to kick the bottom of the handcart frame. This not only causes discomfort but may also cause the person to stumble or the items to vibrate, seriously affecting the smoothness and comfort of pushing the cart. This is a long-standing ergonomic problem that has plagued users but has not been effectively solved.

[0004] Furthermore, the existing trolleys typically have an open platform structure and do not provide effective securing devices to restrain luggage. Therefore, during the process of pushing, especially when turning, starting and stopping, or passing over uneven surfaces, stacked luggage is prone to swaying and shifting due to inertia, and in severe cases, it may even fall off. This unstable state not only forces travelers to interrupt their journey and stop to laboriously reorganize their luggage, increasing the inconvenience of the trip, but also makes it easier for the aforementioned kicking of the trolley frame to occur in the rush when pushing it again after reorganization, forming a vicious cycle. Utility Model Content

[0005] The purpose of this application is to provide an airport trolley that is designed to prevent kicking, thereby improving the problems of existing airport trolleys where the user's foot is easily kicked by the frame and the luggage placed on them is unstable.

The adjustment frame has a plurality of holes arranged along its length, and the slid has a plug rod that can be selectively inserted into the aforementioned holes. The fixing assembly includes a fixing sleeve, a take-up shaft rotatably disposed within the fixing sleeve, a strap wound around the take-up shaft, a hook connected to the end of the strap, a ratchet fixed on the take-up shaft, a pawl pivotally disposed on the fixing sleeve, and a spring providing elastic force to the pawl. The longitudinal frame is offset toward the child carrier side of the stroller body, and the fixing component is mounted on the adjusting component by its fixing sleeve, while the spring inside keeps the pawl engaged with the ratchet.

[0007] By adopting the above technical solution, the trolley can be flexibly adapted to luggage items of different sizes and quantities.

[0008] Preferably, the card sleeve is provided with a magnet, which is magnetically attracted to the crossbar.

[0026] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0027] A kick-proof airport trolley, reference Figures 1-6 It includes a stroller body 1, with multiple wheels 2 rotatably connected to the bottom of the stroller body 1, a handle 3 for pushing by people fixedly connected to the upper part of the stroller body 1, a child carrier 4 fixedly installed on the stroller body 1, and also includes an adjustment component 5 and a fixing component 6. The adjustment assembly 5 includes a longitudinal frame 501 and a transverse frame 502 fixedly connected to the main body 1 of the trolley. The longitudinal frame 501 serves as the rear support of the storage platform. It is located on the main body 1 of the trolley and is offset towards the side of the child carrier 4 to provide extra space for the feet of the person pushing the trolley when walking. The transverse frame 502 has a groove inside, and the adjustment frame 503 is slidably connected in the groove to adjust the depth of the storage platform. The adjustment frame 503 has multiple spaced holes along its length.

[0028] A retaining sleeve 504 is provided on the outer sliding sleeve of the cross frame 502. A plug rod 505 is fixedly provided on the inner wall of the retaining sleeve 504. The end of the plug rod 505 can be selectively inserted into any hole on the adjusting frame 503, thereby achieving segmented fixing of the extension length of the adjusting frame 503 relative to the cross frame 502. To further enhance the stability of the locking, a magnet 506 is also fixedly provided inside the retaining sleeve 504. When the retaining sleeve 504 slides down to the locking position, the magnet 506 magnetically attracts the surface of the cross frame 502, providing auxiliary positioning and holding force. To ensure the accuracy of the sliding of the retaining sleeve 504, a limiting block 507 is fixedly connected to its outer wall. The inner side of the limiting block 507 forms a sliding fit with the outer side wall of the cross frame 502 to limit the stroke of the retaining sleeve 504 and prevent it from rotating.

[0029] The fixing component 6 is fixedly installed on the longitudinal frame 501 of the adjusting component 5 via its fixing sleeve 601, and is used to tie and fix luggage. The fixing sleeve 601 has a rotating reel 602 inside, and a strap 603 is wound on the reel 602. The free end of the strap 603 is connected to a hook 604. The shape of the hook opening of the hook 604 is adapted to the cross section of the rod of the longitudinal frame 501, so that it can be easily and detachably hooked at any height position of the longitudinal frame 501.

[0030] The take-up shaft 602 is also provided with a handle 605 for operation. To achieve unidirectional tightening, a ratchet 606 is coaxially fixedly connected to one end of the take-up shaft 602, and a pawl 607 is pivotally connected to the fixing sleeve 601. The fixing assembly 6 also includes a spring 608, one end of which is connected to the fixing sleeve 601, and the other end abuts against the pawl 607. The elastic force applied by the spring 608 makes the pawl of the pawl 607 always tend to engage with the teeth of the ratchet 606. To facilitate the release of the strap 603, the fixing assembly 6 also includes a paddle 609, which is rigidly connected to the pawl 607 or integrally formed. The handle 605 and the ratchet 606 are coaxially arranged on the take-up shaft 602, forming a compact and direct transmission operation and unidirectional locking unit.

[0031] Working principle: When using this anti-kick airport trolley, firstly, the initial offset setting of the longitudinal frame 501 on the trolley body 1 towards the child carrier 4 creates a basic safe distance between the toes of the pusher and the frame. When further adjustment of the depth of the storage space is needed, the person pushes the sleeve 504 upwards. The sleeve 504, through the insertion rod 505 fixed on its inner wall, pulls the insertion rod 505 out of a hole in the adjustment frame 503, releasing the axial lock on the adjustment frame 503. The person can then freely pull or push the adjustment frame 503 along the slide of the transverse frame 502. After adjusting to the satisfactory length, the sleeve 504 is pushed back downwards, and the insertion rod 505 will be inserted into a new corresponding hole on the adjustment frame 503, thereby re-locking the depth of the storage platform firmly. This allows the trolley to flexibly adapt to luggage of different sizes, while always maintaining sufficient legroom at the rear, structurally avoiding the problem of kicking during the push.

[0032] Secondly, regarding the quick securing and releasing function of luggage, after the luggage is properly placed, the person pulls out the strap 603 from the retractor 602 and hooks the hook 604 at its end onto the rod of the vertical frame 501. Then, the person rotates the handle 605, which drives the retractor 602 and the ratchet 606 fixed thereto to rotate synchronously, thereby tightening the strap 603. During the tightening process, the spring 608 continuously applies a spring force towards the ratchet 606 to the pawl 607, causing the pawl of the pawl 607 to engage with the ratchet 606. The gear teeth generate a one-way jumping engagement, forming a reliable one-way self-locking mechanism. That is, the strap 603 can only be tightened and will not automatically loosen, ensuring the absolute stability of the luggage during transportation. When the luggage needs to be removed, simply press the lever 609. The lever 609 will drive the pawl 607 to overcome the elastic force of the spring 608 and pivot, so that the pawl of the pawl 607 is completely disengaged from the meshing state with the ratchet 606. At this time, the one-way lock is released, the rewind shaft 602 can rotate freely in the opposite direction, and the strap 603 can be easily pulled out and released.
