Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to an airport trolley with luggage protection function. Background Technology

[0002] In large transportation hubs such as airports and train stations, luggage trolleys are commonly provided to facilitate passengers carrying large or heavy luggage. Existing luggage trolleys typically consist of a main body made of metal rods, with a luggage rack underneath for placing luggage, and wheels for movement.

[0003] In the design of these trolleys, there are usually one or more large gaps or openings between the vertical support rods of the main frame and the luggage rack at the bottom, due to structural design requirements. This structure does not pose a problem when passengers need to transport large suitcases. However, when passengers are carrying smaller items such as backpacks, handbags, or shopping bags, these small items are very likely to slip or fall out of the aforementioned structural gaps when the trolley moves, turns, or traverses bumpy surfaces.

[0004] This not only makes it inconvenient for passengers to retrieve their belongings, but may also lead to damage or loss of luggage. Therefore, existing trolleys have obvious design deficiencies in this regard, affecting their practicality and universality for luggage of different sizes. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an airport trolley with luggage protection function, which aims to improve the problem that in the prior art, small luggage is easy to slip off due to the structural gap between the support rod and the luggage rack of the airport trolley, which has functional design defects and lacks effective protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an airport trolley with luggage protection function, comprising: a trolley mechanism, the trolley mechanism including a support rod and a luggage rack; and a protective frame and a connecting mechanism for fixing the protective frame to the support rod.

[0007] The connecting mechanism includes a C-shaped buckle plate, a fastening plate, a pressure plate, and a disc bolt.

[0008] The C-shaped buckle is fixed to the protective frame and cooperates with the fastening plate to surround the support rod; the disc bolt passes through the fastening plate, one end of which is used to drive the pressure plate to abut against the outer wall of the support rod, so as to lock the C-shaped buckle and the fastening plate on the support rod.

[0009] Preferably, the outer wall of the C-shaped buckle is provided with a connecting buckle, and the fastening plate is provided with a connecting hook that engages with the connecting buckle.

[0010] Preferably, one end of the disc bolt is rotatably connected to the pressure plate via a limiting block.

[0011] Preferably, the pressure plate has an internal structure for accommodating and limiting the limiting block.

[0012] Preferably, the airport trolley with baggage protection function further includes a protective mechanism, which is a rubber sleeve fitted onto the outer wall of the protective frame.

[0013] Preferably, the trolley mechanism includes wheels and a push handle.

[0014] Preferably, the protective frame, after installation, spans the gap between the support rod and the luggage rack.

[0015] Preferably, the connecting mechanism is fixed on both sides of the protective frame.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the added protective frame effectively blocks the inherent gap between the trolley support rod and the luggage rack, reliably preventing small luggage or packages from slipping out, and significantly enhancing the trolley's applicability and safety.

[0017] 2. In this utility model, the pressure plate is driven by rotating disc bolts to generate a strong locking force, which realizes the quick installation and disassembly of the protective frame. The whole process is convenient to operate and does not require any additional tools. At the same time, it ensures that the structure after installation is extremely firm and stable and will not shake or fall off during the pushing process.

[0018] 3. In this utility model, the rubber sleeve installed on the outer wall of the protective frame serves two purposes: firstly, it provides cushioning and protection, effectively preventing the hard frame from causing wear or scratches to the surface of the suitcase; secondly, its high coefficient of friction effectively prevents the luggage from slipping, thus improving the stability of the luggage during transportation.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0022] Reference Figures 1-4 One embodiment of this utility model is an airport trolley with luggage protection function, which includes a trolley mechanism 1, a connecting mechanism 2, a limiting mechanism 3 and a protective mechanism 4.

[0023] The trolley mechanism 1 includes a support rod 101 that serves as its frame, a luggage rack 102 for carrying luggage, casters 103 fixedly connected to the bottom of the luggage rack 102, and a push handle 104 fixedly connected to the upper end of the support rod 101.

[0024] The main body of the limiting mechanism 3 is the protective frame 301, which is used to span the gap between the support rod 101 and the luggage rack 102 after installation. The protective mechanism 4 is a rubber sleeve 401 fitted onto the outer wall of the protective frame 301.

[0025] The connecting mechanism 2 is used to detachably fix the protective frame 301 to the support rod 101. Its specific structure is as follows: The connecting mechanism 2 includes a C-shaped buckle plate 201, a fastening plate 203, a disc bolt 205, a limiting block 206, and a pressure plate 207.

[0026] The C-shaped buckle 201 is welded and fixed to both sides of the protective frame 301, and the outer wall of the C-shaped buckle 201 is integrally formed with a connecting buckle 202. One end of the fastening plate 203 is integrally formed with a connecting hook 204 that matches the connecting buckle 202, and the plate body is provided with a threaded hole for the disc bolt 205 to be screwed in. The pressure plate 207 is located between the disc bolt 205 and the support rod 101, and its interior is provided with a cavity that can accommodate and limit the rotation of the limiting block 206. Through this structure, one end of the disc bolt 205 is rotatably connected to the pressure plate 207 via the limiting block 206.

[0027] During installation, first, the C-shaped buckle plate 201 is fitted onto one side of the outer wall of the support rod 101. Then, the fastening plate 203 is attached to the other side of the outer wall of the support rod 101, and the connecting hook 204 and the connecting buckle 202 are engaged, so that the connecting mechanism 2 completely surrounds the outside of the support rod 101. Next, the disc bolt 205 is rotated, moving axially and driving the pressure plate 207 towards the outer wall of the support rod 101, eventually pressing it firmly against it. When the pressure plate 207 presses against the support rod 101, the reaction force generated by the continuous rotation of the disc bolt 205 tightens the engagement between the connecting hook 204 and the connecting buckle 202, firmly locking the entire connecting mechanism 2 onto the support rod 101, thus achieving a stable installation of the protective frame 301. In use, small luggage placed on the luggage rack 102 will be effectively blocked by the protective frame 301, while the rubber sleeve 401 on the outer wall provides anti-wear and anti-slip protection for the luggage.

[0028] Working principle: The limiting mechanism 3 is placed on the trolley mechanism 1, so that the protective frame 301 spans the gap between the support rod 101 and the luggage rack 102. The C-shaped buckle plates 201, which are fixed on both sides of the protective frame 301, are fitted onto one side of the outer wall of the support rod 101. Then, the fastening plate 203 is attached to the other side of the outer wall of the support rod 101, and its connecting hook 204 is engaged with the connecting buckle 202 on the outer wall of the C-shaped buckle plate 201. At this time, the connecting mechanism 2 completely surrounds the outside of the support rod 101. Then, the disc bolt 205 is rotated. Since the disc bolt 205 is threadedly connected to the fastening plate 203, its rotation will cause it to move axially, and drive the pressure plate 207, which is rotated through the limiting block 206 at one end, to move toward the outer wall of the support rod 101 and finally tighten. When the pressure plate 207 presses against the support rod 101, the reaction force generated by the continuous rotation of the disc bolt 205 will cause the fastening plate 203 to move away from the support rod 101, thereby tightening the engagement between the connecting hook 204 and the connecting buckle 202, and finally firmly locking the entire connecting mechanism 2 onto the support rod 101, thus achieving a stable installation of the protective frame 301. After installation, when luggage is placed on the luggage rack 102, the protective frame 301 can effectively prevent small luggage from sliding down the gap between the support rod 101 and the luggage rack 102. The rubber sleeve 401, which serves as the protective mechanism 4, fitted on the outer wall of the protective frame 301, plays a role in preventing wear and slipping on the luggage. Users can push the trolley to transport luggage by holding the push handle 104 and using the moving wheels 103.
