According to the number of rods, there are only two types of trolley cases: single rod trolley case and double rod trolley case. However, many people may not know the internal structure of these two trolley cases very well. Today we will briefly introduce this aspect.
1. Single rod trolley case
The single rod trolley case is not very common in the market. It is composed of a main box, a frame, a wheel frame, and a rod. The main box is a hollow box body composed of a leather-coated frame, and the bottom of the frame is connected with the inner edges on both sides of the frame. This type of trolley case rod mainly consists of a pair of parallel rods and a handle, and the handle spans across the top of each shaft. A gap is opened on the top of the leather back piece, and the tie rod is pulled out through the gap, making the tie rod box stronger and more stable.
2. Double rod trolley case
The main box of the double-rod trolley box is generally a hollow box body composed of a leather-covered frame, and the bottom of the frame is connected with the inner edges on both sides of the frame. The pull rod has a pair of rods and a pull handle. The pull handle spans the top of the two shafts. The bottom end of the shaft is connected with the wheel frame and the frame; this design makes the box and the pull rod stronger. In addition, there is a partition inside the main box, which is used to connect with the side and top pieces of the leather and the trolley box is durable.
Through the above introduction, I believe that everyone has a clear understanding of single-rod trolley cases and double-rod trolley cases. In fact, there is not much difference between double-rod trolley cases and single-rod trolley cases. They have their own advantages. The key is to see which style of trolley case you like.
