Description

Technical Field

[0001] This utility model belongs to the field of teaching aids, specifically relating to a slalom teaching aid for football instruction. Background Technology

[0002] At present, students can only better carry out their studies and life if they improve their physical fitness. At present, schools are offering more and more sports-related classes, and the content available for students to learn is becoming more and more abundant. Among them, football is a favorite subject for most students. However, given the uneven quality of teaching resources, students want to learn but may not have teachers with enough experience to teach them. Moreover, students may not be able to understand the way teachers express and demonstrate their teaching. This creates a conflict between students and teachers. One wants to learn well, and the other wants to teach well, but it is difficult to create enough connection in teaching, making it difficult for teachers to teach students how to play football well. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a slalom teaching aid for football instruction. Slalom is a fundamental part of football and a skill that students can quickly learn. Therefore, this slalom teaching aid is provided. It consists of a disc with a laser head that emits point lasers to indicate the landing point and a laser head that emits line lasers to indicate the trajectory of the football. Teachers teach by observing the indicated points, and students learn by observing the indicated points, which can accelerate the efficiency of students' football learning.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A slalom training tool for soccer instruction includes an upper disc, a lower disc, and a marking assembly. The upper disc has a frustum-shaped structure, with several evenly distributed receiving grooves on its outer wall, each with its central axis as the center of rotation. Four sets of downward-opening insertion grooves are evenly distributed on the bottom surface of the upper disc, each with its central axis as the center of rotation. The lower disc has four sets of support plates on its upper surface, evenly distributed with its central axis as the center of rotation. The support plates correspond to and enclose the insertion grooves to form an insertion cavity for inserting a line-shooting head. Each support plate has a limiting post and a tube groove, and the line-shooting head has a limiting groove and a tube post. The limiting post engages with the limiting groove, and the tube groove engages with the tube post. The insertion groove has a locking opening, and the line-shooting head has a locking groove.

[0006] The marking assembly includes several sets of dot heads and four sets of line heads. The upper end of the dot head is provided with a rotating column that mates with a rotating hole in the receiving groove. The lower end of the dot head is provided with a dot laser head. The line heads are connected to the insertion groove. The lower end face of the line head is provided with a line laser head.

[0007] The lower disc is equipped with a battery compartment, and the dot laser head and the line laser head are electrically connected to the battery compartment respectively. The lower disc is detachably connected to the lower end surface of the upper disc.

[0008] This soccer slalom teaching aid uses an upper and lower disc to form a complete disc. The discs are arranged in a straight line on the grass for slalom instruction. Current slalom instruction relies on footwork and the soccer ball's trajectory. Footwork emphasizes the foot's landing point, while the trajectory is indicated by a line. Since the ball needs to dribble over each disc during the slalom, the discs are equipped with laser dots to mark the landing point and laser lines to mark the trajectory. This facilitates demonstrations by teachers and allows students to easily imitate the landing points and trajectory lines.

[0009] Therefore, the disc was improved by dividing it into an upper disc and a lower disc. The outer wall of the upper disc has several receiving slots with the central axis of the disc as the center of rotation. The receiving slots are equipped with rotating holes. The receiving slots are designed to accommodate the spot laser head. The rotating column on the spot laser head cooperates with the rotating hole. The lower end of the spot laser head is equipped with a point laser head. Therefore, when the spot laser head is rotated, the rotation angle of the spot laser head can be controlled, so that the position of the point laser point emitted by the point laser head can be changed along the radial direction of the upper disc. That is, the position of the point laser point can be changed in the radial direction by rotating the angle of the spot laser head. The receiving slots on the upper disc can cover more positions in the circumferential direction. When teaching, the teacher can rotate the spot laser head on the upper disc as needed to mark the landing point of the emitted point laser point.

[0010] The support plate on the lower disc and the insertion slot on the upper disc form the insertion cavity for the line-shooting head. Since the trajectory of the soccer ball in slalom teaching is generally straight, only four sets of straight laser lines are needed to mark the four directions. Therefore, only four sets of line-shooting heads are required to meet the needs of marking the soccer ball's trajectory. A linear laser head is installed at the bottom of the line-shooting head. After the line-shooting head is inserted into the insertion cavity, the linear laser head is closed. When the line-shooting head is pulled outwards, the tilted linear laser head is energized and emits a straight laser line. During teaching, the instructor can pull out the line-shooting head as needed and mark the trajectory of the soccer ball with the emitted straight laser line. Because the line-shooting head extends excessively inwards… Pushing the nozzle would cause it to fall into the disc, so a support plate was added to the lower disc, and a limiting post was installed on the support plate. The limiting post engages with the limiting groove of the nozzle to prevent the nozzle from falling into the disc when it retracts inward. Since pulling the nozzle outward too much would cause it to fall out, a tube alignment groove was installed on the support plate. The tube alignment post on the nozzle engages with the tube alignment groove to limit the pulling distance of the nozzle and prevent it from falling out when pulled outward. To facilitate pulling out the retracted nozzle, a locking port was installed on the connector slot, and a locking groove was installed on the nozzle. The locking groove and locking port correspond to each other, and the nozzle can be pulled out by hand by holding the locking groove.

[0011] Furthermore, the upper plate is provided with an upper insertion tube, and the lower plate is provided with a lower insertion tube. The upper insertion tube and the lower insertion tube abut against each other and form a through hole that runs vertically through the plate.

[0012] Compared with existing technologies, the advantages of this invention are as follows: By using several rotatable dot laser heads distributed circumferentially, the rotation angle of the dot laser heads can be controlled, allowing the position of the dot laser points emitted by the dot laser heads to be changed along the radial direction of the upper plate, so that the teacher can mark the landing point of the emitted dot laser point; by pulling the line laser head, the inclined line laser head emits a straight laser line after being powered on, and the teacher can pull out the line laser head as needed during teaching to mark the trajectory of the soccer ball; the teacher can use the marked landing point and the trajectory of the soccer ball for teaching, and the students can learn by imitation.

[0021] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

[0022] like Figure 1-5As shown, a slalom training aid for football includes an upper disc 1, a lower disc 2, and a marking assembly 3. The upper disc 1 has a frustum-shaped structure. Several accommodating grooves 11, with the central axis of the upper disc 1 as the center of rotation, are evenly distributed on the outer wall of the upper disc 1. Four sets of insertion grooves 12, with the central axis of the upper disc 1 as the center of rotation and opening downwards, are evenly distributed on the bottom surface of the upper disc 1. The lower disc 2 has four sets of support plates 22 on its upper surface, and the four sets of support plates 22 are positioned at the center of the lower disc 2. The axes are evenly distributed around the center of rotation. The support plate 22 corresponds to and surrounds the insertion slot 12 to form an insertion cavity 13 for the insertion of the wire nozzle 32. The support plate 22 is provided with a limiting post 23 and a tube groove 24. The wire nozzle 32 is provided with a limiting groove 322 and a tube post 323. The limiting post 23 cooperates with the limiting groove 322, and the tube groove 24 cooperates with the tube post 323. The insertion slot 12 is provided with a fastening opening 121, and the wire nozzle 32 is provided with a fastening groove 324.

[0023] The marking assembly 3 includes several sets of dot heads 31 and four sets of line heads 32. The upper end of the dot head 31 is provided with a rotating column 311 that cooperates with the rotating hole 111 in the receiving groove 11. The lower end of the dot head 31 is provided with a dot laser head 312. The line heads 32 are connected to the insertion groove 12. The lower end surface of the line head 32 is provided with a line laser head 321.

[0024] The lower disc 2 is provided with a battery compartment 21. The dot laser head 312 and the line laser head 321 are electrically connected to the battery compartment 21 respectively. The lower disc 2 is detachably connected to the lower end surface of the upper disc 1.

[0025] Furthermore, the upper disc 1 is provided with an upper insertion tube 14, and the lower disc 2 is provided with a lower insertion tube 25. The upper insertion tube 14 and the lower insertion tube 25 abut against each other and form a through hole 4 that runs vertically through the disc.

[0026] Description of the working principle of this utility model:

[0027] This soccer teaching aid, using this structure, consists of an upper disc 1 and a lower disc 2, forming a complete disc. The discs are arranged in a straight line on the grass for slalom instruction. Since current slalom instruction relies on footwork and the soccer ball's trajectory, emphasizing footwork requires focusing on the foot's landing point, while the trajectory is represented by a line. Because the ball needs to dribble over each disc during the slalom, the discs are equipped with laser dots that emit light to mark the landing point and laser lines that emit light to mark the soccer trajectory. This facilitates demonstrations by teachers and allows students to easily imitate the landing points and trajectory lines.

[0028] Therefore, the disc is improved by dividing it into an upper disc 1 and a lower disc 2. Several receiving grooves 11 with the central axis of the disc 1 as the rotation center are distributed on the outer wall of the upper disc 1. The receiving grooves 11 are provided with rotating holes 111. The receiving grooves 11 are designed to accommodate the spot laser head 31. The rotating column 311 on the spot laser head 31 cooperates with the rotating hole 111. The lower end of the spot laser head 31 is provided with a dot laser head 312. Therefore, when the spot laser head 31 is rotated, the rotation angle of the spot laser head 31 can be controlled, so that the position of the dot laser point emitted by the dot laser head 312 can be changed along the radial direction of the upper disc 1. That is, the position of the dot laser point can be changed in the radial direction by rotating the angle of the spot laser head 31. Since several receiving grooves 11 are provided on the upper disc 1, more positions in the circumferential direction can be covered. When teaching, the teacher can rotate the spot laser head 31 on the upper disc 1 as needed to mark the emitted dot laser point at the landing point.

[0029] The support plate 22 on the lower disc 2 and the insertion slot 12 on the upper disc 1 form an insertion cavity 13 for the line-shooting head 32 to be inserted. Since the trajectory of a soccer ball is generally straight in slalom teaching, only four sets of straight laser lines are needed to mark the four directions. Therefore, only four sets of line-shooting heads 32 are needed to meet the requirement of marking the soccer ball's trajectory. A linear laser head 321 is set at the bottom of the line-shooting head 32. After the line-shooting head 32 is inserted into the insertion cavity 13, the linear laser head 321 can be closed. When the line-shooting head 32 is pulled outwards, the tilted linear laser head 321, after being energized, emits a straight laser line. During teaching, the teacher can pull out the line-shooting head 32 as needed and mark the emitted straight laser line on the soccer ball's trajectory. However, pushing the line-shooting head 32 too far inwards will cause it to fall off. The wire emitter 32 falls into the disc tray, so a support plate 22 is added to the lower disc tray 2, and a limiting post 23 is set on the support plate 22. The limiting post 23 cooperates with the limiting groove 322 of the wire emitter 32 to prevent the wire emitter 32 from falling into the disc tray when it retracts inward. Since the wire emitter 32 will fall out if it is pulled out too much, a tube straightening groove 24 is set on the support plate 22. The tube straightening post 323 on the wire emitter 32 cooperates with the tube straightening groove 24, thereby limiting the pulling distance of the wire emitter 32 and preventing the wire emitter 32 from falling out when it is pulled outward. In order to facilitate the pulling out of the retracted wire emitter 32, a locking port 121 is set on the insertion groove 12, and a locking groove 324 is set on the wire emitter 32. The locking groove 324 corresponds to the locking port 121. The wire emitter 32 can be pulled out by hand by holding the locking groove 324.

[0030] In addition, the upper insertion tube 14 in the upper disc 1 abuts against the lower insertion tube 25 in the lower disc 2 to form a through hole 4 that runs vertically through the disc. When the disc is placed on the grass, a pole can be inserted in the middle of the disc to achieve the effect of using a post around a stake.

[0031] The beneficial effects of this utility model are as follows: By controlling the rotation angle of several rotatable dot laser heads 31 distributed circumferentially, the dot laser points emitted by the dot laser head 312 can be changed along the radial direction of the upper plate 1, allowing the teacher to mark the emitted dot laser points on the landing points; by pulling the line laser head 32, the inclined line laser head 321 emits a straight laser line after being energized. During teaching, the teacher can pull out the line laser head 32 as needed and mark the emitted straight laser line on the trajectory of the soccer ball; the teacher can use the marked landing points and the trajectory of the soccer ball for teaching, and students can learn by imitation.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
