Description

Technical Field

[0001] This utility model belongs to the field of luggage cart technology, and specifically relates to a support frame for large luggage carts. Background Technology

[0002] Large baggage handling trolleys are commonly used in airports, hotels, logistics warehouses, and other places for the efficient transport of heavy or large baggage and goods. They have a simple structure and no railings, making it easy to quickly load and unload large bags, equipment, or stack multiple pieces of luggage.

[0003] Traditional luggage trolleys mostly use fixed frames, which generally have the problems of high resistance to movement and laborious operation. When carrying heavy objects, users often need to exert a lot of pushing force to move them, which consumes a lot of physical strength and affects work efficiency. To solve the above problems, we provide a support frame for large luggage trolleys. Utility Model Content

[0004] The purpose of this utility model is to provide a support frame for large luggage carts, in order to solve the problems mentioned in the background art. Traditional luggage carts mostly use fixed frames, which generally have the problems of high movement resistance and laborious operation. When carrying heavy objects, users often need to apply a lot of pushing force to move them, which consumes a lot of physical strength and affects work efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a support frame for a large luggage cart, including a frame, a round rod fixedly connected to the inner side of the frame, a bracket rotatably connected to the surface of the round rod, a movable wheel rotatably connected to the other end of the bracket, two limiting mechanisms provided on the inner side of the bracket, and an insert plate adapted to the limiting mechanism fixedly connected to the inner side of the frame, with an insertion hole opened inside the insert plate;

[0006] The limiting mechanism includes a housing, an insert rod is sleeved inside the housing, a push plate is fixedly connected to the surface of the insert rod, a spring is sleeved on the surface of the insert rod, and one side of the housing is fixedly connected to a bracket.

[0007] Preferably, a base is fixedly connected to the bottom of the frame, a support plate is rotatably connected inside the base, and a magnetic block is fixedly connected to one side of the frame.

[0008] Preferably, a wheel frame is fixedly connected to one side of the frame, and a wheel is rotatably connected inside the wheel frame.

[0009] Preferably, a back plate is fixedly connected to one side of the frame.

[0010] This utility model has the following beneficial effects:

[0011] This device utilizes a linkage design of a plug rod, push plate, and spring. Users simply pull the plug rod to compress the spring, causing the plug rod to disengage from the insertion hole. This allows adjustment of the angle of the bracket on the round rod. After releasing the spring, it automatically resets, pushing the plug rod back into the insertion hole to lock it in place. The operation is simple and quick, enabling rapid angle adjustment. The combination of the bracket and the casters allows the device to stably support large luggage while also enabling flexible movement. This effectively reduces the user's pushing resistance, significantly improving the convenience and labor-saving effect of luggage handling. It has high practical value and promising market application prospects. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example 1:

[0019] refer to Figure 1-4 A support frame for a large luggage cart includes a frame 1, a round rod 2 fixedly connected to the inner side of the frame 1, a bracket 3 rotatably connected to the surface of the round rod 2, a movable wheel 4 rotatably connected to the other end of the bracket 3, two limiting mechanisms 5 provided on the inner side of the bracket 3, and an insert plate 6 adapted to the limiting mechanism 5 fixedly connected to the inner side of the frame 1, with an insertion hole 7 opened inside the insert plate 6.

[0020] The limiting mechanism 5 includes a housing 51, an insert rod 52 is sleeved inside the housing 51, a push plate 53 is fixedly connected to the surface of the insert rod 52, a spring 54 is sleeved on the surface of the insert rod 52, and one side of the housing 51 is fixedly connected to the bracket 3.

[0021] Specifically, the movable wheel 4 is rotatably connected to the bracket 3 via the first wheel axle, and multiple insertion holes 7 are distributed around the rotation axis of the bracket 3. The insertion rod 52 can slide inside the outer shell 51. When one end of the insertion rod 52 is inserted into the inside of the insertion hole 7, the bracket 3 can be limited and fixed.

[0022] refer to Figure 3 and Figure 4 The bottom of the frame 1 is fixedly connected to the base 8, and the support plate 9 is rotatably connected inside the base 8. A magnetic block 10 is fixedly connected to one side of the frame 1. The top of the base 8 is provided with an installation groove. When the support plate 9 is unfolded, the base 8 can effectively reinforce and support the support plate 9 through the installation groove, thereby improving the stability of the support plate 9. When the support plate 9 is folded, it is fixed by the magnetic block 10, which makes it easy to fold and store the support plate 9.

[0023] refer to Figure 1 A wheel frame 11 is fixedly connected to one side of the frame 1. A wheel 12 is rotatably connected inside the wheel frame 11. The wheel frame 11 is rotatably connected to the wheel 12 through a second wheel axle.

[0024] refer to Figure 3 A back panel 13 is fixedly connected to one side of the frame 1. By setting the back panel 13, luggage can be effectively prevented from falling off.

[0025] Brief description of the usage process: The user can pull the insertion rod 52, which causes the push plate 53 to compress the spring 54. Then, one end of the insertion rod 52 is disengaged from the inside of the insertion hole 7. The bracket 3 is then rotated on the surface of the round rod 2. When the bracket 3 is rotated to the adjusted angle, the insertion rod 52 is released, and the spring 54 pushes the insertion rod 52 into the inside of the insertion hole 7 through the push plate 53 for limiting. This allows the device to be effectively supported and moved by the bracket 3 and the moving wheel 4, and makes it easy for the user to push the device with little effort.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
