Tent construction: 1. Two poles, select two main poles, and penetrate them in the cross direction of the corresponding pole pockets on both sides of the door. 2. Insert the two ends of the pole into the corresponding double-hole foot boards respectively, so as to arch the two main poles at the same time to form the basic skeleton of the tent. 3. After the skeleton is formed, put on the outer tent, put on the tent pole from the middle part, and fasten the binding rope. 4. To make the pole pass smoothly, do not use excessive force, and then arch the pole after it is fully in place, so as not to damage the tent pole. 5. The extended space of the outer canopy can store bags, shoes, clothing, food and other items (increase the storage space). The outer canopy door can be rolled up at ordinary times (for easy access). The inner tent door has double layers, double zipper, humanized design, open the layered window sand door, and directly enter the tent. In the tent, you can open the nylon door or the window screen door at will. Free choice. The inner tent has a transom, on the top of the tent, enhancing Air circulation, good ventilation. Every tent is sold with a bag, and many people are accustomed to putting the tent in it. Not to mention that it is very troublesome to fold it properly and put it in. The stowed tent is usually the largest piece of equipment in all our equipment, and the space of the backpack is limited, in addition to the sleeping bag and the moisture-proof pad, two large pieces need to be installed. And the trouble is that many tents have a long cylindrical bag, and if you use a slightly smaller backpack, you may not be able to put it in. Hang the tent outside the backpack? It seems like a good way to save space, but it's not. This guy is easy to cause you trouble outside. The tent is very heavy, and it is not easy to tie it up when hanging outside the backpack, unless it is like a bag of palms; if it is crossed, if the route needs to drill into the woods, it is easy to be caught by branches , if you are accidentally scratched by a branch, you will be miserable. What to do then? The best way is to let go of the constraints brought by the manufacturer's design——Throw away the tent's outer bag and use a large sleeping bag cover instead. When you put it away, you don't have to fold it too much. Just stuff it into the sleeping bag cover like a sleeping bag. If you want to save the volume, you can add a sleeping bag compression strap on the outside to reduce the volume to a small size. In this way, the closed sleeping bag is transformed from the original long tube into a ball, and it is easy to arrange the position in the backpack. The composition of the tourist tent: (1) Fabric: The technical indicators of waterproof fabrics are subject to the degree of waterproofing, and the anti-splashing water is only coated with AC or PU on the surface. Generally only used for children or game tents, waterproof 300MM is generally used for beach tents/shade tents or cotton tents for drought and less rain. Waterproof 800MM-1200MM is used for conventional simple camping tents. Tent, need to travel for many days. Waterproof above 3000MM is generally a professional tent, which has been treated with technologies such as high temperature resistance/cold resistance. Bottom material: PE is generally used, and the quality mainly depends on its thickness and warp and weft density. It is better to use Oxford fabric, and the waterproof treatment should be at least 1500MM or more. The inner fabric is generally breathable nylon or breathable cotton. The quality depends mainly on its density. (2) Supporting skeleton The most common is glass fiber tube. Measuring its quality is more professional and more important. There are several types of tent brackets: 1) Elasticity: This type is generally a children's tent or a beach game tent. 2) The most common is a series of 6.9/7.9/8.5/9.5/11/12.5 fiberglass tubes. The thicker the rigidity, the weaker the softness. Therefore, whether the selection of the fiber tube support is reasonable is determined according to the ratio of the size and height of the ground, and it is easy to break if it is too thick or too thin. For example: 210*210*130 is a relatively classic size, and the tube is generally 7.9 or 8.5. 3) Aluminum alloy skeleton: It is also difficult to test according to the alloy ratio. Generally, the overall radian curve of the original bracket is calculated first and then hot-pressed. The characteristic is that it is light and easy to carry, but it is not easy to fold, but the quality is not good and it is easy to bend and deform.
