Description

Positioning structure of racket frame holder of racket stringing machine

Technical field:

The utility model relates to a racket stringing machine, in particular to a positioning structure of a racket frame holder of a racket stringing machine.

Background technique:

For tennis rackets, badminton rackets and other equipment with a ring-shaped racket frame, the elastic racket string is used to weave a net-shaped hitting surface in the frame, and the hitting surface is in a state of appropriate tension. Produces an effective hitting effect, and the player is easy to control the flying direction of the ball after hitting the ball. The tension of the hitting surface depends on the tensile stress formed by the racket string being stretched when the racket string is weaved to form the hitting surface. In order to make the threading of the racket string easy and the tensile stress value to be accurate, the racket stringing machine is generally used for the racket stringing operation.

Before the racket threading machine stretches and weaves the racket strings, the racket frame of the racket is held and positioned by a pair of racket frame holders provided by the racket threading machine; as shown in Figure 1 and Figure 2, the conventional racket The positioning structure of the frame holder mainly includes a guide plate 2 locked on the top surface of the table plate 1 of the racket stringing machine. Leaning against the top edge of the guide plate 2, the bottom section of the base 4 is hollow, and has a bottom plate 402. Two pins 404 are protruded from the bottom end of the bottom plate 402 to pivot on the guide groove 202, and a locking bolt 5. One end has a plastic rotary head 502, and the other end is threaded through the bottom end of the table 1 and screwed to the bottom plate 402 through the guide groove 202. The locking bolt 5 is pivoted between the rotary head 502 and the table 1. Pivot a washer 504. Accordingly, unscrew the locking bolt 5, and then the base 4 can be pushed to move back and forth along the guide groove 202. After the base 4 matches the racket to be clamped and is displaced to the position, proceed again. By turning and locking the locking bolt 5, the holder 3 can be positioned so that each holder 3 can relatively hold the ring frame of the racket.

Because rackets of various forms mostly have racket frames of different sizes and forms, when each holder 3 holds the racket frame relatively, the distance between each holder 3 often varies with racket frames of different sizes. Therefore, each of the holders 3 cannot only be positioned at a single distance from each other, and can only be used to hold and position rackets of various shapes and sizes. In addition, in order to reduce the space occupied by the racket stringing machine when it is not in use on weekdays After the threading operation is completed, the holders 3 are often moved closer and positioned, and each time the holder 3 is to be displaced and positioned, the locking bolt 5 must be loosened first to release the holder 3. In the positioning state, when the holder 3 is displaced to the desired position, the locking bolt 5 is tightened again to return the holder 3 to the positioning state, which is very cumbersome in operation.
