The number of the hooks is 4, and the tail ends of the hooks are in surface contact with one section of the basket frame.

The shoulder and the hanging shoulder are provided with a matching structure supporting the shoulder and the hanging shoulder to rotate relatively, and an angle locking device is further arranged between the shoulder and the hanging shoulder.

Convex points and concave points which are matched with each other are respectively arranged on the joint surfaces of the shoulder and the hanging shoulder.

4 salient points are evenly distributed on the upper end face of the shoulder along the circumference, and 8 concave points are evenly distributed on the lower end face of the hanging shoulder along the circumference.

The utility model has the advantages that: under the prerequisite that the basketball hit the rim, the basketball is automatic to the return of appointed direction motion under the guide of return bend pipe-shaped section of thick bamboo, can reduce and pick up the ball number of times, reduces the ineffective loss of physical power and time, improves training efficiency and level. The fixed-point shooting repeated training device supports the training of a plurality of shooting angles and can be hung on a basket on any side of a court for training.

Detailed Description

As can be seen from fig. 1, 2, 3, 4 and 5, the fixed-point shooting repetitive training device of the present invention comprises an upper cylinder 1 matched with a basket, wherein the lower end of the upper cylinder 1 is provided with an annular shoulder 10 along the outer circumference thereof, and further comprises a lower cylinder 2, the upper end of the lower cylinder 2 is provided with an annular hanging shoulder 20 along the inner circumference thereof, the shoulder 10 is matched with the hanging shoulder 20, the hanging shoulder 20 can be hung on the shoulder 10, and the two can rotate relatively; the lower end of the lower cylinder 2 is integrally provided with a bent tube-shaped cylinder 3 with an arc-shaped section and an open end, and the bottom arc of the bent tube-shaped cylinder 3 is tangent to the horizontal plane; the inner cavities of the upper cylinder 1, the lower cylinder 2 and the elbow-shaped cylinder 3 are communicated with each other and form a basketball passage.

The section of the elbow-shaped cylinder 3 is arc-shaped, the arc center angle range of the outer edge of the elbow-shaped cylinder is 60 degrees to 90 degrees, and the tail end of the bending surface at one side close to the circle center is cut into a notch, so that the tail end of the bending surface can be opened to enable a basketball to pass through.

As shown in fig. 1, the upper end of the upper cylinder 1 is further provided with a plurality of hooks 11 for hanging the device on a basket; in this embodiment, 4 hooks 11 are provided, the hooks 11 are made of flat metal strips, and compared with rope hooks, the hooks made of metal strips have rigidity and are not deformed in the vertical direction, so that the device can be prevented from deflecting in the shooting process. The hook 11 is preferably made of a flat metal strip with a width of 1 + -0.5 cm and a thickness of 2mm so that its end can hook onto the rim and make surface contact with a section of the rim to prevent deflection. In this embodiment, the upper end of the upper cylinder 1 is formed with a ring of ribs 12 along its outer circumference, the ends of the ribs 12 are bent downward to form a curl 120, the hook 11 is suspended by the curl 120, and the hook 11 and the ribs 12 are separately placed.

As can be seen from figures 3, 4 and 5, the device is hung on the basket through the hook 11 when the utility model works, and the position of the upper cylinder 1 is unchanged. The hanging shoulder 20 is rotatable in a horizontal direction with respect to the shoulder 10, so that the outlet direction of the elbow-shaped cylinder 3 is correspondingly rotated, so that the athlete can perform a plurality of positions training. For locking the training position, a relative angle locking means is provided between the shoulder 10 and the catch 20. The relative angle locking device has various setting modes, such as a convex point and a concave point which are matched with each other are respectively arranged on the combining surface of the shoulder 10 and the hanging shoulder 20. The salient points and the concave points are arranged oppositely, namely the salient points can be arranged on the shoulder 10 or the hanging shoulder 20, and the concave points are correspondingly matched. The number of the convex points and the concave points is set according to the requirement of angle distribution, and the number of the convex points and the concave points can be the same or different.

As shown in fig. 3, 4 and 5, in this embodiment, 4 convex points 13 are uniformly distributed on the upper end surface of the shoulder 10 along the circumference, 8 concave points 23 are uniformly distributed on the lower end surface of the hanging shoulder 20 along the circumference, and the convex points 13 and the concave points 23 have shapes matched with each other, so as to lock the relative angles of the two. Reduce the resistance when complex quantity can reduce the rotation, concave point 23 quantity is 2 times of bump 13 quantity simultaneously, and both are along the circumference equipartition to guarantee that the bump can form the cooperation with certain concave point all the time.

As the lower end face of the hanging shoulder 20 is evenly provided with 8 concave points 23, the central angle formed by every two adjacent concave points 23 is 45 degrees, and when the device is hung on a basket of a standard basketball court, 5 training positions can be formed on the unilateral basketball court. After the athlete finishes training at one position, the elbow-shaped barrel 3 is pushed, the shoulder 10 and the hanging shoulder 20 rotate relatively, the locking is carried out again after the athlete enters the next station, and the athlete continues training.

The utility model discloses mainly be applicable to under unmanned complex prerequisite, the sportsman carries out single accuracy training of shooting. During training, the direction of the elbow-shaped cylinder 3 is adjusted firstly, a player points to a station according to the elbow-shaped cylinder 3 and shoots for training, and on the premise that a basketball hits a basketball hoop, the basketball automatically moves to return to the designated direction under the guidance of the elbow-shaped cylinder 3, so that the times of picking up the basketball can be reduced, and the basketball shooting device is suitable for shooting repetitive training. Meanwhile, the fixed-point shooting repeated training device can be hung on a basket on any side of the court, and supports training of a plurality of shooting angles.
