Technical Field

[0001] The invention belongs to the technical field of badminton racket detection, and in particular relates to a strength detection device for a badminton racket. Background Art

[0002] A badminton racket is generally composed of a racket head, a racket shaft, a racket handle, and the joint between the racket frame and the racket shaft. The length of a racket shall not exceed 68 cm, of which the length between the racket handle and the racket shaft shall not exceed 42 cm, the length of the racket frame shall not exceed 25 cm, and the width shall be 20 cm. The strength of the badminton racket needs to be tested before use.

[0003] A Chinese patent with publication number CN220270974U discloses a strength detection device for a badminton racket, comprising a fixing groove, a rack fixedly connected in the fixing groove, a gear meshed on the rack, a connecting shaft fixedly connected to the gear, one end of the connecting shaft fixedly connected to the output end of the second motor, and the other end of the connecting shaft rotatably connected to a U-shaped plate.

[0004] Although the strength detection device for a badminton racket in the above application detects the badminton string through the detection block, it is unable to detect the torsional force of the racket handle. Usually, during the hitting process of the badminton racket, the racket handle will produce a certain torsional angle, so that the badminton racket as a whole will produce torque, thereby affecting the player's ball control technology. It has torsion resistance, resulting in poor use effect.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a strength detection device for a badminton racket, thereby solving the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A strength detection device for a badminton racket, comprising: a test bench, a support frame is slidably matched on the upper side of one end of the test bench, a handle twisting assembly is rotatably matched in the middle of the upper end of the support frame, a racket shaft support block is installed in the middle of the upper side of the test bench, a racket head placement table is installed on the upper side of the other end of the test bench, a diamond block is rotatably matched in the middle of the racket head placement table, and the racket shaft support block corresponds to the racket handle twisting assembly and the racket head placement table respectively;

[0009] The two opposite ends of the upper side of the diamond block are rotatably engaged with Z-shaped rods, and the upper sides of one end of the two Z-shaped rods are equipped with arc-shaped pressure blocks, and the two arc-shaped pressure blocks are slidably engaged with the upper side of the racket head placement table, and an inverted U-shaped support frame is fixed between the opposite sides above the racket head placement table, and a pressure component located above the two arc-shaped pressure blocks is installed in the middle of the inverted U-shaped support frame, and a pressure sensor electrically connected to the pressure component and the two arc-shaped pressure blocks is installed on one side of the inverted U-shaped support frame.

[0011] By adopting the above technical solution, the first motor is used to drive the screw to rotate, so that the screw cooperates with the lower end thread of the support frame, thereby driving the support frame to move horizontally on the upper side of one end of the test bench, and the distance between the support frame and the racket head placement table can be changed, so as to perform strength testing on badminton rackets of different specifications.

[0012] Optionally, the handle twisting assembly includes a frame rotatably fitted in the middle of the inner side of the upper end of the support frame, a plurality of first springs symmetrically fixed to the relatively inner sides of the frame, two arc blocks respectively fixed to one end of the plurality of first springs, and a plurality of second springs respectively fixed between adjacent ends of two of the arc blocks.

[0013] By adopting the above technical solution, the two arc blocks can be driven to clamp and fix the peripheral side of the handle by using a plurality of first springs symmetrically fixed on the relatively inner sides of the frame, so that the handle is better located between the two arc blocks, and the stability of the handle during detection is effectively improved. In addition, the plurality of second springs respectively fixed between the adjacent ends of the two arc blocks can be elastically expanded and contracted according to the distance between the two arc blocks, so that the two arc blocks are more stable when clamping the handle, and the stability of the handle during detection is further improved.

[0014] Optionally, the handle twisting assembly further includes a second motor fixed to the outer side of the upper end of the support frame, and rubber pads respectively fixed to the inner sides of the two arc blocks, and the output end of the second motor is fixed to one end of the frame.

[0015] By adopting the above technical solution, the second motor can be used to drive the frame to rotate in both directions, so that the frame drives the clamped handle to rotate in both directions, thereby preparing for the next step of the torque sensor to detect the torsional force of the handle.

[0017] By adopting the above technical solution, a movable rod is rotatably matched with the peripheral side of the first rod body, so that the movable rod drives the arc-shaped pressure block to move back and forth on the upper side of the racket head placement table, so that the two arc-shaped pressure blocks move relative to each other synchronously, thereby realizing clamping and pressurizing detection of the peripheral side of the racket head.

[0018] Optionally, two slots are symmetrically provided in the middle of the upper side of the racket head placement table, two of the second rods are slidably fitted in the two slots, and first detection blocks are installed on the inner sides of the two arc-shaped pressure blocks.

[0019] By adopting the above technical solution, the two second rods are slidably matched in the two slots, so that the two arc-shaped pressure blocks can only slide back and forth on the inner walls of the two slots, thereby guiding the two arc-shaped pressure blocks.

[0020] Optionally, the two first rod bodies and the two movable rods are all located inside the racket head placement platform, a gear is fixed to the middle of the lower side of the diamond block, an electric guide rail is installed on one side inside the racket head placement platform, a toothed plate is fixed to the output end of the electric guide rail, and the toothed plate is meshed with the gear.

[0021] By adopting the above technical solution, the electric guide rail can be used to drive the tooth plate to move left and right, so that the tooth plate and the gear mesh and rotate, thereby driving the diamond block to rotate synchronously, preparing for the next step of the two arc-shaped pressure blocks to clamp and pressurize the circumference of the racket head.

[0022] Optionally, the pressurizing assembly includes a cylinder fixed to the middle part of the upper side of the inverted U-shaped support frame, a pressurizing rectangular plate fixed to the output end of the cylinder, and a second detection block installed on the lower side of the pressurizing rectangular plate, and the pressurizing rectangular plate is located above and corresponds to the two arc-shaped pressurizing blocks, and the pressure sensor is electrically connected to the second detection block and the two first detection blocks, respectively.

[0023] By adopting the above technical solution, the set cylinder can be used to drive the pressurized rectangular plate to move downward, so that the pressurized rectangular plate drives the second detection block to move downward synchronously, thereby clamping and pressurizing the surface of the racket head, and completing the strength detection of the racket head surface. At the same time, the pressure sensor is electrically connected to the second detection block and the two first detection blocks respectively, so that the strength information detected by the second detection block and the two first detection blocks is transmitted to the pressure sensor, thereby realizing the detection of the racket head strength.

[0024] Optionally, a torque sensor is installed on the outer side of the upper end of the support frame, and the torque sensor is electrically connected to the two arc blocks respectively.

The racket shaft is supported, and the detection efficiency of the racket head or the racket handle is further improved.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all the advantages described below at the same time:

[0029] 1. By setting a diamond block in the middle of the racket head placement table, the two Z-shaped rods can be driven to move in opposite directions synchronously, so that the two Z-shaped rods drive the two arc-shaped pressure blocks to move away from or close to each other, thereby clamping and pressurizing the surrounding sides of the racket head, completing the strength test of the racket head in the horizontal direction, and using the set pressure component, the surface of the racket head can be clamped and pressurized, thereby completing the strength test of the racket head in the vertical and horizontal directions, greatly improving the comprehensive strength test of the racket head.

[0030] 2. The racket head is clamped and fixed by a pressure component or two arc-shaped pressure blocks, which can ensure that the handle twisting component in the next step maintains a stable state when performing twisting detection on the handle, effectively improving the efficiency of twisting force detection. At the same time, the handle twisting component that rotates and cooperates in the middle of the upper end of the support frame can drive the handle to twist on both sides and detect the maximum torque that the handle can withstand, which plays an important role in solving the twisting resistance of the handle in the next step, so that players can give full play to the ball control technology when playing badminton and improve its use effect.

DETAILED DESCRIPTION

[0043] The present invention will now be described in further detail with reference to the accompanying drawings.

[0044] See also Figure 1-7As shown, in this embodiment, a strength detection device for a badminton racket is provided, comprising: a test bench 1, a support frame 2 is slidably matched with the upper side of one end of the test bench 1, a handle twisting assembly 3 is rotatably matched with the middle part of the upper end of the support frame 2, a racket shaft support block 4 is installed in the middle part of the upper side of the test bench 1, a racket head placement platform 5 is installed on the upper side of the other end of the test bench 1, a diamond block 6 is rotatably matched with the middle part of the racket head placement platform 5, and the racket shaft support block 4 corresponds to the racket handle twisting assembly 3 and the racket head placement platform 5 respectively;

[0045] The two opposite ends of the upper side of the diamond block 6 are rotatably matched with Z-shaped rods 7, and the upper sides of one end of the two Z-shaped rods 7 are equipped with arc-shaped pressure blocks 8. The two arc-shaped pressure blocks 8 are slidably matched with the upper side of the racket head placement table 5, and an inverted U-shaped support frame 9 is fixed between the opposite sides above the racket head placement table 5. A pressure component 10 located above the two arc-shaped pressure blocks 8 is installed in the middle of the inverted U-shaped support frame 9, and a pressure sensor 11 electrically connected to the pressure component 10 and the two arc-shaped pressure blocks 8 is installed on one side of the inverted U-shaped support frame 9.

[0046] The working principle of this device is as follows: when it is necessary to perform strength testing on a badminton racket, first move the support frame 2. At this time, the support frame 2 moves horizontally on the upper side of the test bench 1, so that the support frame 2 moves toward or away from the side of the racket head placement table 5, thereby clamping badminton rackets of different specifications, and then extend the handle of the badminton racket into the handle twisting assembly 3 in the middle of the upper end of the support frame 2 and fix it. At the same time, place the racket head and the racket shaft of the badminton racket on the racket head placement table 5 and the racket shaft support block 4 respectively, and then rotate the diamond block 6 so that the diamond block 6 drives the two Z-shaped rods 7 to move in the opposite direction synchronously, so that the two Z-shaped rods 7 drive the two arc-shaped pressure blocks 8 to approach each other. At this time, the lower sides of the two arc-shaped pressure blocks 8 slide and cooperate with the upper side of the racket head placement table 5, so as to realize clamping and pressurizing testing on the surrounding side of the racket head.

[0047] When it is necessary to clamp and pressurize the surface of the racket head, the pressurizing component 10 is started. At this time, the pressurizing component 10 moves downward so that the lower end of the pressurizing component 10 is in contact with the surface of the racket head and clamping and pressurizing detection is performed on it. Then the pressure sensor 11 is started. At this time, the pressurizing component 10 and the two arc-shaped pressurizing blocks 8 transmit the strength data obtained by the detection to the pressure sensor 11. At the same time, the pressure sensor 11 receives and processes the strength data obtained by the detection to realize the strength detection of the racket head.

[0048] When the torsional force of the handle needs to be tested, the pressure component 10 or the two arc-shaped pressure blocks 8 are first used to clamp the racket head, and then the handle twisting component 3 is started. At this time, the handle twisting component 3 drives the handle to twist on both sides and detects the maximum torque that the handle can withstand, thereby completing the detection of the torsional force of the handle.

[0049] It should be noted that all electrical devices involved in this application can be powered by batteries or external power supplies.

The output end of the second motor 18 is fixed to one end of the frame 14.

[0051] When clamping the badminton racket, the first motor 13 is started first, and the output end of the first motor 13 drives the screw rod 12 to rotate, so that the screw rod 12 cooperates with the lower end thread of the support frame 2 and drives the support frame 2 to move closer to or away from the side of the racket head placement platform 5, thereby clamping badminton rackets of different specifications, and then the handle of the badminton racket is extended into the middle part of the frame 14. At this time, the two arc blocks 16 in the frame 14 drive the two arc blocks 16 to approach each other according to the elasticity of the multiple first springs 15 and the multiple second springs 17, so that the rubber pads inside the two arc blocks 16 are attached to the surrounding side of the handle, so that the two arc blocks 16 clamp and position the handle, effectively improving the stability of the handle during detection, and then the second motor 18 is started, and the output end of the second motor 18 drives the frame 14 to rotate, so that the frame 14 drives the clamped handle to twist on both sides, and detects the maximum torque that the handle can withstand, thereby completing the detection of the torsional force of the handle.

[0053] When clamping and pressurizing the peripheral side of the racket head, the electric guide rail 24 is started first, and the output end of the electric guide rail 24 moves the tooth plate 25 left and right, so that the tooth plate 25 meshes with the gear 23 and rotates and drives the diamond block 6 to rotate synchronously, so that the diamond block 6 drives the two first rod bodies 19 to move synchronously. At this time, the two first rod bodies 19 rotate with one end of the two movable rods 20 and drive them to move synchronously, and then the other ends of the two movable rods 20 drive the two movable rods 20 to slide and fit in the two slots 22 respectively. At this time, the two movable rods 20 respectively drive the two arc-shaped pressure blocks 8 to approach each other on the upper side of the racket head placement table 5. At this time, the two first detection blocks are attached to the peripheral side of the racket head and clamped and pressurized, so as to achieve clamping and pressurization of the peripheral side of the racket head.

[0054] When the surface of the racket head is clamped and pressurized, the cylinder 26 is started first, and the output end of the cylinder 26 drives the pressurizing rectangular plate 27 to move downward. At this time, the second detection block on the lower side of the pressurizing rectangular plate 27 is in contact with the surface of the racket head and is clamped and pressurized to achieve clamping and pressurizing of the surface of the racket head.

[0055] When the strength of the racket head is detected, the pressure sensor 11 is started. At this time, the second detection block and the two first detection blocks transmit the detected strength data to the pressure sensor 11. At the same time, the pressure sensor 11 receives and processes the detected strength data to realize the detection of the strength of the racket head.
