Technical Field
[0001] The utility model relates to the technical field of badminton inclination angle detection, in particular to a detection tool for detecting the inclination angle of a badminton. Background Art
[0002] The structure of badminton Figure 1 As shown, it includes a ball head 1, on which a plurality of feathers 2 are evenly arranged along its circumference. After a batch of badminton shuttlecocks are produced in the workshop, the process requires that a certain number of shuttlecocks be drawn out and then tested for their inclination angles [the inclination angle refers to the angle between any feather 2 of the shuttlecock and the horizontal plane]. The testing method in the workshop is:
[0003] S1. A worker takes out a badminton to be inspected from a material basket and places the head 1 of the badminton on the inspection table while holding the badminton still.
[0004] S2. The worker uses a protractor to measure the angle between any feather 2 of the badminton and the horizontal plane. This angle is the inclination angle of the badminton. If the inclination angle is within the designed range, the worker determines that the badminton is qualified. If the inclination angle is not within the designed range, the worker determines that the badminton is unqualified, thus completing the inclination angle test of a badminton.
[0005] S3. The worker repeats the operations of steps S1 to S2 to complete the detection of the inclination angles of multiple badmintons to be inspected in the material basket.
[0006] However, although the detection method in the workshop can detect the inclination angle of the badminton, it still has the following technical defects in actual operation:
[0007] I. Since the opening angles of the feathers 2 on the badminton are inconsistent relative to the ball head 1, the inclination angle measured by the protractor is not the actual inclination angle of the badminton, resulting in a technical defect of low detection accuracy.
[0008] II. In steps S1 to S2, workers are required to straighten the badminton at all times so that the inclination angle of the badminton can be measured with a protractor. However, there are many badmintons to be tested, and straightening the badminton by hand each time undoubtedly increases the workload of the workers.
[0009] Therefore, there is an urgent need for a testing tool that can reduce the workload of workers and improve the accuracy of badminton inclination detection. Utility Model Content

[0034] A vertical plate 11 is fixedly provided on the rear end face of the base 5, and a knob 12 is fixedly provided on the rear end face of the vertical plate 11. A semicircular plate 13 is fixedly provided on the top surface of the vertical plate 11 with the knob 12 as the center line. An angle scale is opened on the front end face of the semicircular plate 13 along its circumference. A bent plate 14 is sleeved on the knob 12. The other end of the bent plate 14 passes forward through the area surrounded by the vertical plate 11 and the semicircular plate 13, and a swing arm 15 is fixedly provided on the extended end and is radially distributed along the semicircular plate 13. A leaning block 16 is fixedly provided on the front end face of the swing arm 15, and the inner end end of the leaning block 16 is a triangular head. An arched slider 17 is fixedly provided on the rear end face of the upper end portion of the swing arm 15, and the arched slider 17 leans against the front end face of the semicircular plate 13. The inner end face 18 of the arched slider 17 is in the same straight line as the tip of the triangular head of the leaning block 16.
[0035] A spring 19 is sleeved around the knob 12. One end of the spring 19 presses against the bent plate 14, while the other end is fixed to the screw cap of the knob 12. A threaded hole 20 is defined within the pressure block 8, extending through the arcuate surface 9. The pressure block 8 is threadedly connected to the threaded section of the adjustment screw 10 via the threaded hole 20. A mounting seat 21 is fixed to the base plate 3, located to the left of the base 5. An annular ring 22 is fixed to the mounting seat 21, located directly above the circular hole 6.
[0036] The working process of this utility model is as follows:
[0037] S1. Fixing the badminton to be tested. The specific steps are as follows:
[0038] S11, the worker takes out a Figure 1 As shown in the figure, the badminton to be tested is passed through the annular ring 22 with the ball head 1 facing downwards and inserted into the circular hole 6 of the base 5. At this time, each feather 2 of the badminton is surrounded by the annular ring 22.
[0039] S12, the worker turns the adjusting screw 10. Under the cooperation of the threaded section of the adjusting screw 10 and the pressing block 8, the pressing block 8 moves along the opening 7 of the base 5 toward the ball head 1. After a certain number of turns, the arc surface 9 of the pressing block 8 fixes the ball head 1, thereby fixing the badminton to be tested. Figure 10 As shown;
[0040] S2. The worker manually moves the swing arm 15, which drives the bent plate 14, the arched slider 17, and the support block 16 to rotate synchronously around the center line of the knob 12. At the same time, the arched slider 17 rotates against the semicircular plate 13. When the triangular head of the support block 16 contacts a feather 2 of the badminton, the worker stops moving the swing arm 15. At this time, the worker reads the scale indicated by the inner end surface 18 of the arched slider 17. The scale is the inclination angle of the badminton. If the inclination angle is within the designed range, the worker determines that the tested badminton is qualified; if the inclination angle is not within the designed range, the worker determines that the tested badminton is unqualified, thereby completing the inclination angle test of a badminton.
[0041] S3. The worker loosens the adjusting screw 10 to separate the pressing block 8 from the ball head 1. After separation, the worker takes away the tested badminton;
[0042] S4. The worker repeats the operations of steps S1 to S3 to continuously detect the inclination angles of multiple badmintons.
[0043] Among them, it can be seen from step S1 that since each bristle piece 2 of the badminton is surrounded by the annular ring 22, it is ensured that the opening angle of each bristle piece 2 on the badminton relative to the ball head 1 is consistent, thereby ensuring that the measured inclination angle is the actual inclination angle of the badminton. Therefore, compared with the method of measuring with a protractor, this inspection tool improves the measurement accuracy of the badminton inclination angle.
[0044] In addition, since the head 1 of the badminton to be tested is always fixed in the circular hole 6 of the base 5 by the pressing block 8, the worker does not need to straighten the badminton by hand to test the inclination angle of the badminton, thereby reducing the worker's workload.
[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
