[0002] The primary purpose of a racket's striking performance test is to ensure that the racket's performance and quality meet standards, thereby improving a player's striking effectiveness and performance. This testing encompasses multiple aspects designed to comprehensively evaluate a racket's various performance indicators. These tests not only examine the racket's physical properties, such as string tension, weight balance, deflection, and vibration, but also analyze and test the racket's materials for durability. These tests ensure the racket's stable performance during use, enhancing a player's striking consistency and accuracy, ultimately improving their performance.

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figure 1-Figure 3 An embodiment of the present invention is a testing machine for the striking performance of a carbon fiber racket, comprising a mounting base 1 and a mounting frame 2 slidably mounted on the mounting base 1, the mounting base 1 being provided with a striking mechanism 3 for controlling the mounting frame 2, and the mounting frame 2 being provided with an adjusting mechanism 4 for adjusting the striking range; the striking mechanism 3 comprising two groups of symmetrically distributed bidirectional screw rods 301, the mounting frame 2 being slidably sleeved with the two groups of bidirectional screw rods 301 respectively, and two groups of symmetrically distributed springs 302 being sleeved on the bidirectional screw rods 301, the striking mechanism 3 further comprising two groups of symmetrically distributed cams 306, both groups of cams 306 being rotatably connected to the mounting base 1 through a rotating shaft, both groups of cams 306 being fitted with the mounting frame 2, the adjusting mechanism 4 comprising an adjusting rod 401 being slidably connected to the mounting frame 2, and the adjusting rod 40 There are four groups of adjustment blocks 403 symmetrically distributed around the periphery. A first support rod 404 and a second support rod 405 are provided between the four groups of adjustment blocks 403 and the adjustment rod 401, and the first support rod 404 and the second support rod 405 are cross-distributed. A first screw rod 402 is provided in the mounting frame 2. The four groups of adjustment blocks 403 and the left end of the adjustment rod 401 are each provided with a striking hammer 406. The striking mechanism 3 is provided to automatically strike the mounting frame 2 and the striking hammer 406. The bidirectional screw rod 301 cooperates with the stopper 303 to adjust the compression degree of the spring 302, thereby adjusting the striking force of the striking performance tester. The adjusting mechanism 4 is provided to adjust the number of striking hammers 406 acting simultaneously and the striking area and range of the striking hammer 406.

[0025] In this embodiment, reference Figure 2As shown, two groups of symmetrically distributed blocks 303 are sleeved on the bidirectional screw rod 301, and the blocks 303 are slidably connected to the mounting base 1, and the two ends of the spring 302 are fixedly connected to the blocks 303 and the mounting bracket 2 respectively. The two ends of the bidirectional screw rod 301 respectively penetrate the mounting base 1 and are rotatably connected to the mounting base 1 through bearings. The two ends of the two groups of bidirectional screw rods 301 respectively penetrate the two groups of blocks 303 and are threadedly connected to the blocks 303. The right ends of the two groups of bidirectional screw rods 301 are sleeved with synchronous wheels 304. A synchronous belt 305 is provided in the mounting base 1, and the synchronous belt 305 is respectively connected to the two groups of synchronous wheels 304 for transmission. Start the motor in the mounting base 1 to drive the two groups of cams 306 to rotate. During the rotation of the cams 306, the mounting frame 2 is intermittently pushed to move the striking hammer 406 and compress the spring 302, so that the mounting frame 2 drives the striking hammer 406 to reciprocate on the mounting frame 2 to complete the striking test of the racket. At the same time, the distance between the two groups of blocks 303 is adjusted by rotating the bidirectional screw, thereby adjusting the compression amount of the two groups of springs 302, and adjusting the moving range and moving speed of the mounting frame 2, thereby adjusting the striking force of the racket.

[0026] In this embodiment, reference Figure 3 As shown, the left end of the first support rod 404 is slidably connected to the adjustment block 403, the right end of the first support rod 404 is rotatably connected to the mounting bracket 2 through a rotating shaft, the left end of the second support rod 405 is rotatably connected to the adjustment rod 401 through a rotating shaft, the right end of the second support rod 405 is rotatably connected to the adjustment block 403 through a rotating shaft, the right end of the first screw rod 402 passes through the mounting bracket 2 and is rotatably connected to the mounting bracket 2 through a bearing, the left end of the first screw rod 402 passes through the adjusting rod 401 and is threadedly connected to the adjusting rod 401, the striking hammer 406 is slidably connected to the corresponding adjusting block 403, and a second screw 407 is provided in the adjusting block 403, and the right end of the second screw rod 407 passes through the adjusting block 403 and is rotatably connected to the adjusting block 403 through a rotating shaft. The bearing is rotatably connected to the adjustment block 403, and the left end of the second screw 407 passes through the striking hammer 406 and is threadedly connected to the striking hammer 406. The motor in the mounting frame 2 is started to drive the rotation of the first screw 402, and the adjustment rod 401 is pushed under the limiting action of the mounting frame 2. During the sliding process of the adjustment rod 401, the first support rod 404 and the second support rod 405 are cooperated to adjust the opening degree of the four groups of adjustment blocks 403, thereby realizing the adjustment of the range of action of multiple groups of striking hammers 406. According to actual test requirements, the motor in each adjustment block 403 can be started separately to drive the rotation of the second screw 407 to realize the adjustment of the number of actions of the striking hammer 406.

[0027] When this embodiment is working, according to the actual model of the racket to be tested, the motor in the mounting frame 2 is started to drive the rotation of the first screw 402, and the adjustment rod 401 is pushed under the limiting effect of the mounting frame 2. During the sliding process of the adjustment rod 401, the first support rod 404 and the second support rod 405 are cooperated to adjust the opening degree of the four groups of adjustment blocks 403, thereby adjusting the range of action of multiple groups of striking hammers 406. According to actual test requirements, the motor in each adjustment block 403 can be started separately to drive the rotation of the second screw 407 to adjust the number of actions of the striking hammers 406. After the range of action is regulated, the motor in the mounting base 1 is started to drive the two groups of cams 306 to rotate. During the rotation of the cam 306, the mounting frame 2 is intermittently pushed to fit therewith. The mounting frame 2 drives the striking hammer 406 to move and compresses the spring 302, so that the mounting frame 2 drives the striking hammer 406 to reciprocate on the mounting frame 2 to complete the striking test of the racket. At the same time, the distance between the two groups of blocks 303 is adjusted by rotating the bidirectional screw, thereby adjusting the compression amount of the two groups of springs 302, and adjusting the moving range and moving speed of the mounting frame 2, thereby adjusting the striking force of the racket.
