DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] See also Figure 1-Figure 5 The utility model provides a foldable airport luggage trolley, which comprises a push plate, a push handle 3 and a universal wheel 4 to form a trolley as a whole.

[0030] The push plate is composed of a first placement plate 1 hingedly connected to a second placement plate 2. The first placement plate 1 and the second placement plate 2 are hingedly connected to each other through the hinge connection so that they can be folded together when not in use, thereby saving space.

[0031] A through hole 12 is provided on the outside of the first placement plate 1, and a moving slider 13 is symmetrically provided in the middle of the through hole 12, so that the moving slider 13 can be relatively moved by pulling the moving slider 13 with one hand, and the operation is easier. The moving sliders 13 are connected by a telescopic rod 15, and a spring 2 16 is provided on the outer sleeve of the telescopic rod 15, so that the spring 2 16 pushes the moving slider 13 so that the moving slider 13 pushes the outer push rod 14 to be fixed by a pin to avoid loosening during movement. A limiting slide groove 17 is provided in the middle of the through hole 12 to penetrate outward, and the moving slider 13 and the outer push rod 14 are fixed by a pin. The sliding connection of the limiting slide groove 17 is limited to limit the moving slider 13 to prevent the moving slider 13 from driving the push rod 14 to rotate, and the position where the moving slider 13 can be pulled is set to correspond to the length of the assembly rod 110. The other side of the moving slider 13 is connected to the push rod 14, and the outer side of the push rod 14 is connected to a rectangular assembly rod 110, so that the assembly rod 110 on the outer side of the push rod 14 fixes the push handle 3 to prevent it from flipping. The inner side of the first placement plate 1 is symmetrically provided with a fixing groove 5 inwardly to fix the rod 7. Insert and fix, so that they all adopt the method of latch, which is easier and faster to operate. The outer side of the through hole 12 is provided with a stabilizing block 19 with a middle hole and is movably connected to the push rod 14, so that the push rod 14 is more stable during movement, and the push rod 14 is prevented from shifting, so that the assembly rod 110 is more convenient to insert into the assembly groove 113. The second placement plate 2 is symmetrically provided with through movable holes 6 on both sides, and a fixing rod 7 is provided inside the movable hole 6. The outer side of the fixing rod 7 is connected with a draw buckle 8, and the inner side of the fixing rod 7 is connected to the fixing groove 5, so that the fixing rod is pulled by the draw buckle 8. 7 can be inserted into or pulled out of the fixing groove 5, so as to fix the first placement plate 1 and the second placement plate 2, making it convenient to place items on the upper end. A pushing groove 9 is provided in the middle of the movable hole 6, and a spring 11 is installed inside the pushing groove 9 and is sleeved on the outside of the fixing rod 7. A force plate 10 is provided inside the pushing groove 9 to connect the fixing rod 7 with the fixing rod 7. Through the action of the spring 11, the fixing rod 7 is supported by the force plate 10, so that it can be stably inserted into the fixing groove 5 to prevent the fixing rod 7 from loosening due to the influence of shaking.

[0032] Universal wheels 4 are installed on the outer sides of the bottom end surfaces of the first placement plate 1 and the second placement plate 2 to facilitate the movement of the cart.

[0033] A force-bearing rotating wheel 111 is connected to the bottom end of the push handle 3, so as to facilitate the force to drive the push handle 3 to rotate. A connecting rotating rod 112 is arranged on the inner side of the force-bearing rotating wheel 111 and is connected to the first placement plate 1 through a bearing. A rectangular assembly groove 113 is arranged on the inner side of the connecting rotating rod 112 and is connected to the assembly rod 110. The rectangular assembly groove 113 and the assembly rod 110 increase the contact surface and make the fixing effect better. In addition, the rectangular setting makes it possible for the force-bearing rotating wheel 111 to drive the connecting rotating rod 112 to flip and fold, and the assembly groove 113 can also be flipped to allow the assembly rod 110 to be inserted therein, so as to avoid shaking after folding. Grooves 114 are symmetrically arranged on the outer side of the push handle 3, so that the push handle 3 contacts the fixing rod 7 after flipping, so that it wraps the fixing rod 7 and fixes it, making the whole more stable and convenient for storage.

[0034] Working principle: when the parts need to be folded and stored, first pull the buckle 8 so that the fixing rod 7 can be flipped out of the fixing groove 5 through the force plate 10 to compress the spring 11, so that the second placement plate 2 can be flipped to the upper end of the first placement plate 1, and then the thrust slider 18 is pulled relatively to compress the telescopic rod 15 and the spring 16 while pulling the assembly rod 110 on the outside of the push rod 14 out of the assembly groove 113, and then the push handle 3 is flipped onto the second placement plate 2 through the force rotating wheel 111 and the connecting rotating rod 112, so that the groove 114 on the push handle 3 contacts the fixing rod 7, and then the thrust slider 18 is released to allow the assembly rod 110 to be inserted into the assembly groove 113 for fixation, thereby realizing the fixation of the push handle 3 and fixing the second placement plate 2, thereby completing the folding work.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
