Tie rod: To choose the built-in, the material must be steel, because the external tie rods and wheels cannot adapt to the brutal loading and unloading of each flight.
Box: A steel frame is required, and the fabric is preferably rain-proof. The granularity of the material is better because it is more wear-resistant.
Wheels: Needless to say, they must be built in. The wheels need four wheels to turn 360 degrees, which is more convenient and lightweight. The material of the wheels is of course rubber. The lower the sound when pulling on the ground, the better.
Zipper: It depends on the material and the feel of the trial pull.
When buying a hard travel case, consumers should first check the appearance of the box, that is, whether the box is square and the corners of the box are symmetrical. You can put the box upright or upside down on the ground to see if the box is on all fours and does not skew.
Whether the box surface is smooth, whether there are scratches or cracks, pay special attention to the four corners of the box shell (upper and lower) to be symmetrical. Open the box and check the opening of the box. The openings of the boxes should be close to each other. The gap should be small. The hinges should be flexible. The hinges should rotate flexibly without jamming. The Kema (buckle) can be closed, buckled, and opened. It should be firmly adhered, and the textile fabrics must not jump or crack.
The pull rod should be free to expand and contract, with a certain strength, the expansion rod and the fixed rod should be matched properly, and the expansion should not be too large. After the lock button of the pull rod is pressed, the pull rod should be able to telescope smoothly.
The box running wheel should rotate flexibly. It is best to use the wheel with bearings. When checking the box lock, you can arbitrarily combine several sets of numbers for testing, and the opening and closing can be normal.
When purchasing a travel soft case, first of all, pay attention to whether the zipper is smooth, whether there is missing teeth, misalignment, whether the stitching is straight, and the upper and lower lines should match, no empty needles, jump stitches, general box corners, corners are easy to have Jumper.
Secondly, it depends on whether there is any disability in the box or on the box surface (such as broken fabric, warp, weft, yarn splitting, etc.), and the inspection methods of accessories such as tie rods, walking wheels, and box locks are the same as the methods of purchasing travel hard boxes.
The suitcase is easy to be damaged when using the handle, lever and walking wheel.
Box handles are mostly plastic parts, and the quality of plastics should be checked when selecting. Generally speaking, good quality plastics have certain plasticity, and poor quality plastics are hard and brittle, and are prone to breakage during use.
Most of the box pull rods are retractable. When selecting, press the lock button repeatedly and stretch several times. The pull rod should be able to expand and contract freely. The clearance between the fixed rod and the telescopic rod should be moderate. The expansion cannot be too large.
When selecting the wheels for the box, the simple method is to put the box upside down, the wheels leave the ground, and turn the wheels by hand to make them idle. The wheels must be light and flexible, and the wheels and axles are not tight or loose. Check them one by one. After the wheels, you can drag the box on the ground and drag it back and forth. The whole box is as good as manual.
