Description

Racket clamping structure of racket stringing machine

technical field

The utility model relates to a component of a racket stringing machine, in particular to a racket clamping structure of the racket stringing machine when the racket stringing machine is threaded.

Background technique

As shown in Figure 6, it is a kind of existing racket stringing machine, this racket stringing machine has a base 90, this base 90 is respectively provided with a brace 92 on the front and back sides of the racket frame 91, and on the left and right The two sides of the racket frame 91 are respectively provided with a clamping piece 93 for clamping and positioning. Each clamping piece 93 controls the clamping action with a pulling part 930 as shown in the figure. When the pulling part 920 is pulled down toward the outside (as the clamping part on the left side in the figure), the racket frame 91 can be clamped, and if the racket frame 91 is to be released, the pulling part 930 is pulled up (as shown in the clamping part on the right side in the figure). Holder pattern), you can loosen the racket frame 91, which can assist the racket frame 91 in clamping and positioning and facilitate the racket string to be threaded.

However, when the racket frame 91 is threading, the staff's hands are applied around the base 90. When the clamping part 93 is in a clamping state, its trigger part 930 is turned outwards, so the staff's It is quite easy for the hand to cause the clamping part 93 to break away from the clamping of the racket frame 91 due to the misalignment of the trigger part 930, and it must be repositioned to continue threading.

Therefore, how to solve the clamping problem of the racket frame of the above-mentioned existing racket stringing machine is the key point of the present utility model.

Detailed ways

Please refer to Fig. 1 to Fig. 5, shown in the figure is the selected embodiment structure of the utility model.

This embodiment provides a racket clamping structure for a racket stringing machine, which is installed on the base 1 of the racket stringing machine to position the racket frame 2. In this embodiment, as shown in Figure 1, the base 1 is provided with Four sets of racket clamping structures, these four sets of racket clamping structures are opposite to each other on both sides of the base 1, each racket clamping structure includes a base 3, a sliding part 4, a pressing plate 5, and a reset elastic Item 6, of which:

As shown in Figures 1-2, the base 3 is used to be fixed on the base 1 of the racket stringing machine. In this embodiment, the base 3 has two locking parts 30 at the bottom, and each locking part has a female thread. After the base 3 is positioned on the base 1 , the bolt 31 passes through the base 1 and is locked on the locking portion 30 .

The sliding part 4 is arranged on the base 3, and one end of the sliding part 4 facing the racket frame 2 has an abutting part 40, and the other end is provided with a shaft 41, and the shaft 41 extends toward the rear end of the base 3. , the sliding member 4 abuts against the peripheral side of the racket frame 2 with the abutting portion 40 .

As shown in Figures 2 to 3, there is a slide rail 32 on the base 3, and a slide groove 42 is provided at the bottom of the slide member 4, and the slide groove 42 is slidingly set corresponding to the slide rail 32, so the slide member 4 can be placed on the slide rail 32. Slide horizontally on base 3.

As shown in FIGS. 2 to 3 , the slider 4 of this embodiment has an abutment portion 40 on the upper and lower sides respectively. Each abutment portion 40 is an elastic cushion body. The opening 7 opened outwards at an angle, in which the racket frame 2 is evenly supported by the two abutting portions 40 .

As shown in Figures 2 to 3, the shaft rod 41 of this embodiment is sleeved with a compression spring 43 at the other end of the sliding member 4 and a blocking piece 44 is set, and the compression spring 43 is supported by the blocking piece 44 at one end. Blocking, while the other end is propped against the base 3, and the compression spring 43 is used to prop up the rear when the shaft 41 moves forward with the slider 4.

As shown in Figures 2 to 3, the pressing plate 5 extends into the base 3, and the exposed part forms a toggle end 50, the pressing plate 5 has a perforation 51 in the base 3, the shaft 41 Then pass through the through hole 51 in the base 3 , the diameter of the through hole 51 is slightly larger than the shaft diameter of the shaft 41 , so that the pressure plate 5 can tilt slightly relative to the shaft 41 .

As shown in Figures 2 to 3, the return elastic member 6 is also penetrated by the shaft 41 in the base 3, and one end of the return elastic member 6 abuts against the base 3, and the other end abuts against the pressure plate 5, and as shown in FIG. 4 , the pressing plate 5 maintains an oblique swing and blocks the displacement of the shaft 41 with the corner 510 of the through hole 51 .

As shown in Figure 3, the return elastic member 6 of this embodiment can be opened in a fan shape, and an insertion rod 60 is stretched at one end of the pressure plate 5, and the pressure plate 5 is provided with a perforation 52 relative to the insertion rod 60, and the return elasticity The piece 6 is inserted into the through hole 52 of the pressure plate 5 with its insertion rod 60 .

As shown in Figures 3 to 4, the sliding member 4 is pushed forward and abuts against the racket frame 2 with the abutting portion 40. At this time, because the pressure plate 5 is supported by the reset elastic member 6, it swings obliquely, so that the shaft 41 is blocked by the corner 510 of the pressing plate 5, so the lateral displacement of the shaft 41 is limited, and the slider 4 cannot move backwards, so as to maintain the slider 4 at the abutting position. As shown in Figure 5, when the racket frame 2 on the base 1 is to be loosened, the toggle end 50 of each pressing plate 5 is moved in the direction of the slider, so that the pressing plate 5 is in a vertical state on the shaft rod 41. When the wall angle 510 of the pressure plate 5 breaks away from the shaft rod 41, and the shaft rod 41 is retracted by the elastic force of the compression spring 43, the slider 4 then moves backward along with the shaft rod 41, and the racket frame breaks away from each The racket frame 2 can be removed from the base 1 by the abutment of the abutting portion 40 .

It is not difficult to find the advantages of the utility model from the above description, that is, the telescopic pressing plate 5 of each control slider 4 exposes the toggle end 50 upwards, so when the staff performs the threading operation of the racket frame 2, the staff's hands are on the racket. The work around the frame 2 is not easy to touch the toggle end 50, so it can prevent the sliding part 4 from breaking away from the abutment of the racket frame 2 due to accidental touch, so it can ensure that the racket frame 2 is positioned on the base 1 during the threading operation, so that the threading The job went smoothly.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, All still belong to within the scope of the technical solution of the utility model.
