TECHNICAL FIELD

[0001] The utility model relates to the technical field of detecting badminton balance degree, especially a detection tool for detecting badminton balance degree. BACKGROUND

[0002] Badminton hitting sports are deeply loved by people, and the types of badminton appearing on the market are gradually increasing. Some badminton is made of goose feather, and some badminton is made of plastic. The structure of a certain badminton is shown in Figures 1-2 It comprises a wooden cylindrical head 1, the end of the wooden cylindrical head 1 is a spherical surface 2, an annular plastic ring 3 is embedded on the other end surface of the wooden cylindrical head 1, a plurality of hair rods 4 are uniformly distributed on the annular plastic ring 3 along the circumferential direction thereof, the connecting line between each hair rod 4 is a conical surface, and a layer of meshed conical plastic sheet 5 is covered on the conical surface. Among them, the axis of the wooden cylindrical head 1 and the axis of the conical plastic sheet 5 are on the same straight line.

[0003] Before the workshop mass-produces this kind of badminton, 8 badminton need to be pre-produced, and then the balance degree of these badminton is detected, that is, whether the axis of the wooden cylindrical head 1 of the badminton and the axis of the conical plastic sheet 5 are on the same straight line is detected.

[0004] Among them, the method for detecting the balance degree of the badminton in the workshop is:

[0005] S1, the worker takes out a badminton, supports the large end surface of the conical plastic sheet 5 of the badminton on the platform, and observes the wooden cylindrical head 1 and the conical plastic sheet 5 of the badminton from the front of the platform. If the worker observes that the wooden cylindrical head 1 has an angle relative to the conical plastic sheet 5, the worker judges that the balance degree of the badminton does not meet the requirements, that is, the axis of the wooden cylindrical head 1 and the axis of the conical plastic sheet 5 are not on the same straight line, and the worker judges that the badminton is unqualified;

[0006] If the worker observes that the wooden cylindrical head 1 has no angle relative to the conical plastic sheet 5, the worker judges that the balance degree of the badminton meets the requirements, that is, the axis of the wooden cylindrical head 1 and the axis of the conical plastic sheet 5 are on the same straight line, and the worker judges that the badminton is qualified;

[0007] S2, after 8 badminton are all detected, the worker counts the number of unqualified products. If the number of unqualified products exceeds 2, the worker adjusts the production process of the badminton; if the number of unqualified products is less than 2, the worker can mass-produce the badminton according to the existing production process.

[0008] However, although the method used in the workshop can detect the balance degree of the badminton, there are still the following technical defects in the technology:

[0009] In step S1, since the large end face of the conical plastic piece 5 is uneven, when the worker supports the large end face of the conical plastic piece 5 of the shuttlecock on the platform, the wooden cylindrical head 1 and the conical plastic piece 5 are both in an inclined state, thereby affecting the worker's observation of the wooden cylindrical head 1 and the conical plastic piece 5, leading to the worker's misjudgment of the qualified shuttlecock as unqualified or misjudgment of the unqualified shuttlecock as qualified, and thus reducing the detection precision of the balance degree of the shuttlecock.

[0010] The annular plastic ring 3 can be initially in an inclined state, that is, the annular plastic ring 3 is not coaxial with the wooden cylindrical head 1, and thus the conical plastic piece 5 is initially in an inclined state, thereby leading to the worker's misjudgment of the qualified shuttlecock as unqualified, and further reducing the detection precision of the balance degree of the shuttlecock.

[0038] The working process of the utility model is as follows:

[0039] S1, the worker takes out a badminton as Figures 1-2 shown, and holds the conical plastic piece 5 of the badminton with his hand, and then puts the wooden cylindrical head 1 of the badminton between the arc-shaped grooves 19 of the clamping blocks 15 of the left clamping mechanism 7 and the right clamping mechanism 8, and ensures that the annular plastic ring 3 of the badminton is just between the two pressing rods 17;

[0040] S2, the locking and fixing of the wooden cylindrical head 1 of the badminton, the specific operation steps are:

[0041] S21, the worker loosens the first locking screw 16 on the left clamping mechanism 7 and the first locking screw 16 on the right clamping mechanism 8, under the elastic restoring force of the spring 13, the spring 13 drives the limiting plate 12 to move inward, the limiting plate 12 drives the square rod 10 to move inward, and the square rod 10 drives the connecting rod 14 and the clamping block 15 to move inward synchronously, at this time, the wooden cylindrical head 1 of the badminton is just limited between the two clamping blocks 15;

[0042] S22, the worker tightens the first locking screw 16 on the left clamping mechanism 7 and the first locking screw 16 on the right clamping mechanism 8, and the first locking screw 16 fixes the square rod 10 in the fixed block 9 again, so as to finally realize the locking and fixing of the wooden cylindrical head 1 of the badminton, as Figures 8-9 shown, at this time, the conical plastic piece 5 of the badminton is in a suspended state;

[0043] S3, the fixing of the annular plastic ring 3 of the badminton, the specific operation steps are:

[0044] S31, the worker loosens the second locking screw 18 on the left clamping mechanism 7 and the second locking screw 18 on the right clamping mechanism 8, and then pushes the handle 24 of the left clamping mechanism 7 with the left hand, and pushes the handle 24 of the right clamping mechanism 8 with the right hand, the handle 24 drives the round rod 11 to move inward, and the round rod 11 drives the pressing rod 17 to move inward, so that the annular plastic ring 3 of the badminton is pressed and fixed between the two pressing rods 17, as Figure 10 shown, at this time, the annular plastic ring 3 is guided, so that the annular plastic ring 3 is coaxial with the wooden cylindrical head 1, and then the conical plastic piece 5 of the badminton is guided;

[0045] S32, the worker tightens the second locking screw 18 on the left clamping mechanism 7 and the second locking screw 18 on the right clamping mechanism 8, so as to fix the round rod 11 in the fixed block 9 again;

[0046] S4, the worker looks down from above to observe the wooden cylindrical head 1 and the conical plastic sheet 5 of the shuttlecock. If the worker observes that the wooden cylindrical head 1 has an angle relative to the conical plastic sheet 5, the worker determines that the balance of the shuttlecock does not meet the requirements, that is, the axis of the wooden cylindrical head 1 and the axis of the conical plastic sheet 5 are not on the same straight line, and the worker determines that the shuttlecock is unqualified;

[0047] If the worker observes that the wooden cylindrical head 1 has no angle relative to the conical plastic sheet 5, the worker determines that the balance of the shuttlecock meets the requirements, that is, the axis of the wooden cylindrical head 1 and the axis of the conical plastic sheet 5 are on the same straight line, and the worker determines that the shuttlecock is qualified, thereby completing the detection of the balance of the first shuttlecock;

[0048] S5, the worker repeats the steps S1-S4 to complete the detection of the balance of the remaining 7 shuttlecocks;

[0049] S6, after the detection of the 8 shuttlecocks is completed, the worker counts the number of unqualified products. If the number of unqualified products exceeds 2, the worker adjusts the production process of the shuttlecock. If the number of unqualified products is less than 2, the worker can mass-produce the shuttlecock according to the existing production process.

[0050] In step S2, the detection tool first locks and fixes the wooden cylindrical head 1 of the shuttlecock through the cooperation of the left clamping mechanism 7 and the right clamping mechanism 8, the clamping block 15 and the first locking screw 16, so that the conical plastic sheet 5 of the shuttlecock is in a suspended state. Then in step S4, the worker looks down from above to observe the wooden cylindrical head 1 and the conical plastic sheet 5 of the shuttlecock, thereby completing the detection of the balance of the shuttlecock. Therefore, compared with the detection method in the workshop, the detection tool effectively avoids the influence of the inclined state of the wooden cylindrical head 1 and the conical plastic sheet 5 on the worker's observation after the large end surface of the conical plastic sheet 5 of the shuttlecock is supported on the platform, thereby avoiding the worker's mistake of judging the qualified shuttlecock as unqualified or the unqualified shuttlecock as qualified, and greatly improving the detection accuracy of the balance of the shuttlecock.

[0051] In addition, as can be seen from step S3, the detection tool only needs to cooperate the round rod 11, the pressing rod 17 and the second locking screw 18 of the left clamping mechanism 7 and the right clamping mechanism 8 to fix the annular plastic ring 3 of the shuttlecock between the two pressing rods 17, so that the annular plastic ring 3 is coaxial with the wooden cylindrical head 1, and the conical plastic sheet 5 of the shuttlecock is guided. Therefore, the conical plastic sheet 5 is in a guided state when detected by the worker, effectively avoiding the mistake of judging the qualified shuttlecock as unqualified when the conical plastic sheet 5 is initially in an inclined state, thereby further improving the detection accuracy of the balance of the shuttlecock.
