[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see the appendix Figure 1-5 A racket frame pressure testing device according to an embodiment of the present invention includes a fixed frame 1. A groove 11 is provided in the lower inner part of the fixed frame 1. When fixing the racket, the racket needs to be placed into the groove 11 through the top of the fixed frame 1. Since the differences between badminton rackets of different specifications are often small, no time is spent on adjustment during testing. Often, fine-tuning can be used to clamp and fix badminton rackets of different models. A fastener 2 is slidably connected to one side of the groove 11. The fastener 2 is then used to fix the side of the racket head to keep it in a vertical state. A positioning member 3 is provided on one side of the fastener 2. The positioning member 3 fixes the shaft. A limiting member 5 is provided on one side of the positioning member 3. The limiting member 5 limits and fixes the positioning member 3.
[0030] The positioning component 3 includes multiple support spring rods 31, which are evenly spaced and distributed to distribute the support points and provide more uniform support for the racket shaft. Furthermore, the multiple support spring rods 31 are all vertically positioned to prevent the racket shaft from tilting or shifting after fixing. The support spring rods 31 are connected within the groove 11, and a support plate 32 is fixedly connected to the top of each support spring rod 31. At least two limiting sleeves 33 are slidably connected to the outer side of the support plate 32. The two limiting sleeves 33 are independent of each other and are slidably connected to the fixing frame 1. Some rackets... In terms of design, it presents a gradual size effect. The two limiting sleeves 33 are set independently to facilitate tight fixation of different positions of the racket shaft, improving the stability of the fixation effect. Multiple continuously set triangular tooth blocks 36 are fixedly connected to the outer side of the limiting sleeve 33. Under the action of multiple support spring rods 31, the support plate 32 always maintains an upward force, while the limiting sleeve 33 limits and fixes the racket shaft by moving downward, which is opposite to the force of the multiple support spring rods 31. This can maintain the stability of the racket shaft and prevent the racket frame from being affected by the shaking of the racket shaft during pressure testing.
[0031] The limiting member 5 includes a limiting plate 53, which is slidably connected to the groove 11 and meshes with a plurality of triangular toothed blocks 36. One side of the limiting plate 53 is continuously bent, which can mesh with a plurality of continuous triangular toothed blocks 36, thereby limiting and fixing the limiting sleeve 33.
[0032] One end of the fixed frame 1 is slidably connected to a pressing member 4, and the other end of the fixed frame 1 is fixedly connected to a fixing plate 6, which is used to limit the racket head.
[0033] The limiting component 5 also includes a pull plate 51. A fixing rod 52 is fixedly connected to one side of the pull plate 51. One end of the fixing rod 52 is fixedly connected to the limiting plate 53. A cavity 7 is opened and communicated on one side of the groove 11. A tension spring 54 is fixedly connected between the limiting plate 53 and the cavity 7. The tension spring 54 is located outside the fixing rod 52. When disassembling, the pull plate 51 is pulled outward, thereby driving the fixing rod 52 and the limiting plate 53 to move outward. Then the limiting plate 53 separates from the multiple triangular tooth blocks 36, so that the limiting sleeve 33 stops limiting the racket stick. The racket stick can be taken out from between the limiting sleeve 33 and the support plate 32.
[0034] The pressing component 4 includes a sliding groove 41, which is located at one end of the groove 11. A lead screw 42 is rotatably connected inside the sliding groove 41. One end of the lead screw 42 extends out of the sliding groove 41 and is fixedly connected to an adjustment knob. A pressing plate 43 is slidably connected to the outside of the lead screw 42. The lead screw 42 is used to press against the racket handle. By rotating the adjustment knob, the pressing plate 43 can be moved to press against the rear end of the racket handle. At the same time, the racket head presses against the fixing plate 6, thereby fixing the entire racket.
[0035] A rubber pad 35 is fixed on the top of the support plate 32, and an anti-slip pad 34 is fixed on the upper inner side of the limiting sleeve 33. The anti-slip pad 34 and the rubber pad 35 are both arc-shaped on opposite sides. The anti-slip pad 34 and the rubber pad 35 have good flexibility and anti-slip properties, which can increase the contact area with the racket shaft and improve the effectiveness and reliability of the fixation.
[0036] Fastener 2 includes a positioning plate 21, which is slidably connected in the groove 11. One end of the positioning plate 21 extends out of the groove 11 and is fixedly connected to an adjusting screw 22. The adjusting screw 22 is rotatably connected to the fixed frame 1. By rotating the adjusting screw 22, the positioning plate 21 can be moved to limit and fix the racket head, so that the racket head is completely vertical, thus avoiding affecting the accuracy of the pressure test results.
[0037] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
