What is the length of the badminton racket line?

The net length of the vertical bar is 5.5 meters, which is about 8.5 times of the total length of the racket. The net length of the horizontal line is 4.5 meters, which is about 6.5 times of the total length of the racket.

Extended data:

1. Selection of badminton line: Badminton line has different levels of combination and special production technology in terms of rebound performance, durability, ball control performance, shock absorption performance, hitting feel, etc., to meet the combination needs of different types of players, different rackets and different styles of play. ?

When choosing a badminton racket, you should generally choose according to your own badminton racket type, requirements and playing style. As far as all kinds of badminton rackets on the market are concerned, YONEXBG65 is the first choice for amateurs (but also the most counterfeit products on the market), followed by brands such as Li Ning, Shengli and Forrest.

Tip: Beginners can use elastic, wear-resistant and economical feather thread (generally around 25 yuan).

Second, the badminton racket threading method

Comparison between two-point threading method and four-point threading method

Two-point threading method: first weave the racket line, and then tighten it on the machine. The threading process will use an auxiliary tool: the threading hook. Four-point threading method: shoot above the machine, thread-root first and then tighten-root, and do not use threading hook when threading.

Comparison between the two: the use of threading hook makes the racket line and threading hook, and the racket line and racket line form strong friction, which destroys the surface layer of racket line.

It causes great damage to the racket string before use, and the result is that the racket string is not resistant to beating and the weight is reduced. Two-point threading: in the process of tightening the vertical line, pull from one side of the racket to the other.

Four-point threading method: in the process of tightening the firm thread, start from the middle of the racket and pull it to the left and right sides.

Comparison between the two methods: the ordinary threading method makes the stress on the left and right sides of the racket uneven during the pulling process, while the professional threading method makes the stress on the two sides of the racket more uniform, with better balance and longer service life.

Two-point threading method: "Two-point threading method" is adopted for the stay wire. That is, the root line is pulled to the end, the horizontal lines and vertical lines are connected together, the number of pounds is the same, and there are two knots, so it is called "two-point method".

Four-point threading method: "Four-point threading method" is adopted for pulling wires. That is, the horizontal line and the vertical line are pulled separately, and the number of pounds of the horizontal line is 10% more than that of the vertical line, and the horizontal line and the vertical line have two knots and * * four knots, so it is the "four-point method".

The reason for this is to pull the vertical line first in the process of pulling the wire. The line is not blocked at this time. When the vertical bar is pulled out, the vertical bar has been tightened.

But when the horizontal line crosses the vertical line, the lines cross alternately, so when the horizontal line is pulled, it will be blocked by the tight vertical line, and the line will bend up and down. Therefore, it is necessary to increase the tension of 10% to finally keep the actual number of pounds of the horizontal line and the rigid line consistent. (Vertical: 5.5m, horizontal: 4.5m)

Third, the specific steps of threading

The threading should be prepared for various shooting methods. At the same time, in order to reduce the damage to the thread when shooting, both threading methods are to wear the vertical line first and then the horizontal line.

1. Go through the middle. After the racket string is scattered, start from the middle hole of the racket and walk up and down until the end of one side of the racket frame (hole 1 1 above, hole 12 below, and hole1/below is left blank), and reserve a thread end of about 800M for the racket.

2. Start from one side. Thread the thread from the12nd hole on either side of the racket frame, and the10th hole on the top (the 1 1 hole on the bottom is empty) until the opposite side comes out at the same position, leaving an 80M thread end for the racket.

3. wear a horizontal line. Go through the ninth hole below. Someone threaded the horizontal line from the tenth hole, and then left the ninth hole blank. According to the situation of tennis racquet machine, the threading at the top of racquet frame can be worn as far as possible where it can be pulled and pushed.

Because some lines are very thin, when crossing the common hole between the horizontal line and the solid line, we should try our best to avoid the entanglement between the horizontal line and the vertical line, otherwise the horizontal line will be pressed tightly when pulling the vertical line, and it will be difficult to pull or seriously damage the horizontal line when pulling the horizontal line.
