Description

Technical Field

[0001] The utility model relates to the technical field of strength testing, in particular to a badminton racket strength testing device. Background Art

[0002] A badminton racket is a very common piece of fitness equipment. It has a simple structure and consists of a racket body, a racket string and other parts. After the racket string is produced, in order to make its strength meet the requirements of use, it is usually tested for strength with the help of relevant equipment.

[0003] In a Chinese patent with the authorization publication number CN216594483U, a strength detection device for a badminton racket is disclosed. With the cooperation of a detection block and a detection plate, the device passes the string used on the badminton racket through the second through hole of the detection block and the first through hole of the detection plate, and fixes the two ends of the string. With the cooperation of a motor, a screw, a guide rod and a slider, the output shaft of the motor drives the screw to rotate, and the screw drives the detection block to move through the slider, thereby performing a lateral strength detection on the badminton racket string, adjusting the two detection blocks and the detection plate to the same vertical direction, and with the cooperation of a second cylinder and a support plate, adjusting the height of the detection plate to perform a vertical strength detection on the badminton racket string.

[0004] The above patent has the following defects: However, when testing the vertical strength, if the strings are not disassembled and the detection plate is directly pressed down, because only part of the strings are wrapped around the surface of the detection block, the detection plate can only perform vertical strength testing on the strings wrapped around the detection block, resulting in a limited detection range. If the detection range needs to be increased, the best way for the staff is to disassemble the strings and then place the strings on the surface of the detection block. However, this method requires extra time to disassemble the strings, which will reduce the detection efficiency. For this reason, a badminton racket strength testing device is proposed. Utility Model Content

[0005] The utility model aims to provide a badminton racket strength testing device to solve the problem that when the existing device proposed in the above-mentioned background technology tests the vertical strength, if the racket strings are not disassembled, the detection plate is directly driven to press down. Because only part of the racket strings are wound around the surface of the detection block, the detection plate can only perform vertical strength detection on the racket strings wound around the detection block, resulting in a limited detection range. If the detection range needs to be increased, the best way for the staff is to disassemble the racket strings and then place the racket strings on the surface of the detection block. However, this method requires extra time to disassemble the racket strings, which will reduce the detection efficiency.

[0012] Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects:

[0013] 1. The utility model cooperates with the test bench, the fixing plate and the badminton racket vertical strength test assembly, so that when the device detects the badminton racket string, it can not only test the tensile strength, but also the vertical strength, thereby increasing the accuracy of the detection.

[0014] 2. The utility model cooperates with each other through the tensile strength test structure, the fixing mechanism and the driving device, so that when the device performs strength testing on the badminton racket strings, a large range of testing can be performed on the racket strings at a time without disassembly, thereby solving the problem that when the existing device performs vertical strength testing, if the racket strings are not disassembled, the detection plate is directly driven to press down, because only part of the racket strings are wound around the surface of the detection block. Therefore, the detection board can only perform vertical strength testing on the racket strings wound around the detection block, resulting in a limited detection range. If the detection range needs to be increased, the best way for the staff is to disassemble the racket strings and then place the racket strings on the surface of the detection block. However, this method requires extra time to disassemble the racket strings, which reduces the problem of detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example

[0027] In the Chinese patent with the authorization publication number CN216594483U, when testing the vertical strength, if the strings are not removed and the test plate is directly pressed down, because only part of the strings are wrapped around the surface of the test block, the test plate can only perform vertical strength testing on the strings wrapped around the test block, resulting in a limited test range. If the test range needs to be increased, the best way for the staff is to remove the strings and then place them on the surface of the test block. However, this method requires extra time to remove the strings, which will reduce the test efficiency.

[0028] See also Figure 1-4 The utility model provides a technical solution: a badminton racket strength testing device, including a test bench 1, a fixed plate 2 is fixed on the surface of the test bench 1, in order to detect the vertical strength of the badminton racket strings and increase the detection accuracy, an electric push rod 301 is arranged on the surface of the test bench 1, and a pressure plate 302 is arranged on the surface of the electric push rod 301, in order to detect the lateral tensile strength of the badminton racket strings, a rotating shaft 401 is arranged on the surface of the test bench 1, and a roller 402 is fixed on the bottom of the rotating shaft 401.

[0029] In order to fix the badminton racket string to the surface of the roller 402 and ensure the stability during the tensile test, a sliding rod 501 is fixed to the surface of the roller 402, and a clamping plate 502 is slidably sleeved on the surface of the sliding rod 501, and a threaded rod 503 is threadedly connected to the surface of the clamping plate 502, one end of the threaded rod 503 is connected to the roller 402 bearing, and a knob 504 is fixed to the other end of the threaded rod 503. In order to enable the equipment to perform tensile testing on the badminton racket string on both sides and realize lateral strength testing, a worm gear 601 is fixed to the top of the rotating shaft 401, and a worm 602 is meshingly connected to the surface of the worm gear 601, and two sections of spiral teeth in opposite directions are arranged on the surface of the worm gear 602, and two worm wheels 601 are arranged, one end of the worm gear 602 is connected to a vertical plate 603 with a bearing, and the other end of the worm gear 602 is provided with a motor 604, and the vertical plate 603 and the motor 604 are both interconnected with the test bench 1.

[0030] The model of the motor 604 is ASF120A 250W.

[0031] The working principle or structural principle is that the string of the badminton racket is first placed on the surface of the fixed plate 2, and then one end is wound around the surface of the roller 402. After that, the knob 504 is turned to drive the threaded rod 503 to rotate. Since the threaded rod 503 is threadedly connected to the clamping plate 502, when the threaded rod 503 rotates, the clamping plate 502 is displaced, thereby pressing and fixing the string. Repeat the above operation to fix the other end of the string. Then, if it is necessary to test the vertical strength of the string, the staff can operate the electric push rod 301 to drive the pressure plate 302 to move downward, thereby pressing and fixing the string. Vertical compression is performed to realize vertical strength detection. If it is necessary to detect the lateral strength, the staff can directly start the motor 604 to drive the worm 602 to rotate. Because the worm 602 and the worm wheel 601 are meshed with each other, when the worm 602 rotates, it will drive the worm wheel 601 to rotate. At the same time, because the surface of the worm 602 is provided with two sections of spiral teeth in opposite directions, when the worm 602 rotates, it will drive the two worm wheels 601 to rotate in the opposite direction, thereby driving the two rotating shafts 401 and the roller 402 to rotate in the opposite direction, and then stretch the racket strings to realize the lateral strength detection operation.

[0032] The device has the advantages of high detection accuracy and convenient operation.
