Backpack fastener tips

Backpack fastener is an indispensable part of backpack production, but many people don't know much about backpack fastener. Today, I've sorted out some relevant knowledge about backpack fastener. Let's get to know it.

Backpack fasteners are generally divided into insert buckle (also known as side open buckle), day buckle, ladder buckle, hook buckle and rope buckle. In addition, there are some special purposes. Now let's introduce the characteristics, uses and strength of these fasteners  

1. Insert buckle

The selected materials of fasteners are generally POM (polyoxymethylene, commonly known as saigang), PP and NY. The plug buckle is composed of male buckle and female buckle. One end is fixed with webbing, and the other end can be adjusted through webbing. The length of webbing can be selected according to different needs. It is generally used for the fixation of shoulder and waist. In order to give more effective play to the role of the buckle, the production company is also changing constantly to reduce the weight and ensure the same strength, such as V-shaped buckle. There are also three-way buckles, i.e. "Y" buckles, which are commonly used on safety products such as strollers and taxi seat belts.

2. Day buckle

Its materials are generally POM, PP and NY. Generally speaking, the day buckle is used on the shoulder belt of backpack and satchel to adjust the length of webbing. In order to prevent slip, the cross bar in the middle of the buckle is designed with stripes on many days, and the two side cross bars are expanded to place their own logo, which is almost the same in shape.

3. Ladder buckle

Its materials are generally PP, POM and NY. The ladder buckle is also used to shrink the webbing. It is generally used at the tail of the shoulder belt to adjust the fit of the backpack. There are few classics in the shape and function design of ladder buckle. Duraflex's duckbill ladder buckle can be regarded as an immortal classic.

4. Rope buckle

Rope buckle materials are generally PP, NY and POM. Using the elasticity of the spring ring, the rope can be stuck in dislocation. The rope mouth can be selected with caliber, single hole and double hole. It is suitable for all kinds of OO rope, nylon rope and elastic rope. The logo can be designed according to the requirements of customers. The design of rope buckle has been greatly different from the past. There are a wide variety of metal materials.

5. Hook and buckle

The buckle materials are generally from PP, NY and POM. The hook is generally used on the side of the shoulder bag, with one side connected with the D ring and the other side connected with the webbing. Now many alloy elements have been added to make the hook stronger.
