Trolley case is a necessary tool for people to travel. The high utilization rate of trolley case makes us put forward higher requirements on whether the trolley case is durable. Trolley case trolley is of course the key, so how do we judge the quality of the trolley when we choose the trolley case? The following are the judgment methods summarized in the actual combat:
1. Load bearing.
A good trolley case needs strict requirements at the time of production. At present, the trolley cases produced by many manufacturers have been strictly tested. For example, in terms of weight bearing, the general requirement is to be able to easily carry a weight of 29 kg. That is to say, no matter the size of the trolley case, it is not a problem to ensure that it can hold anything within 29 kg.
2. Shake.
The pull rod of the trolley case is now generally of several sections, which can meet the needs of people of different heights. The pull rod must be solid. When we choose it, we can pull it out in sections and shake it slightly to see if it is stable. Slight shaking is normal. For large pipe sleeves and small pipes, the more the number of pull rod joints, the higher the shaking degree will be. Therefore, for the same model, the smaller size pull rod is looser than the larger size pull rod. All slight shaking amplitude is also normal. However, the particularly large shaking amplitude must be the reflection of poor quality and poor workmanship. Light shaking is better than light shaking. When dragging the box, the ground friction is uneven. The joint of the pull rod must be a few centimeters away, so that people can exert the least force when dragging the box, and keep a buffer space between the pull rod and the box, which is conducive to protecting the pull rod.
3. Pull.
When testing the pull rod, be sure to test the locking button several times more. After pressing it, the pull feel is better. The good feel is that the grip fits the hand shape, and the sensitivity and smoothness of the joint are good. The pulling process does not jam smoothly, the gear locking bite sound is crisp, coherent and labor-saving, and has a very solid and lubricating feeling. The pull rod that is too jammed is not a good pull rod.
4. Pipe wall material and thickness
The thickness of the pull rod is not necessarily related to the strength. Don't always think that the thin rod is not firm and the thick rod is good. The material and pipe wall thickness are the decisive factors. The thin appearance does not mean that the pipe is thin. Some pull rods look thick, but the wall is very thin, and the material is different, and the performance is different, such as aluminum alloy and stainless steel. All aluminum is the best, titanium aluminum alloy is also good, and iron is relatively low-end. It is recommended to choose aluminum alloy that is not easy to rust. In addition, aluminum is less brittle than carbon steel at ultra-low temperature, and is easy to be recycled and remelted, which is in line with the concept of environmental protection. The strong plastic feeling and poor glossiness of the rod body are both the reflection of poor quality. The relatively poor quality rod can be found to have no metallic luster when you look carefully. The plastic feeling is very heavy. A good pull rod can withstand all kinds of pressure.
