Description
Technical Field
The invention relates to the field of machinery, in particular to a turning limiting device for discus training.
Background
Discuses originated from the activities of throwing stone chips by ancient greeks in the first 12-8 th century of the Gongyuan. The 18 th three generations of Olympic games in 708 b.c. are listed as one of five full-featured projects. The discus is initially a disk-shaped stone and is then gradually made of metals such as copper, iron and the like. In the history of the modern olympic games, there have been games (left hand + right hand) where both hands throw a discus. The discus throwing technology has been developed through in-situ throwing, lateral rotating throwing and back rotating throwing. The discus can be made of wood or other suitable materials such as rubber, and the man discus has a weight of 2 kg and a diameter of 22 cm; the female discus weighs 1 kg, has a diameter of 18.1 cm, and is filled with water in the center. In a game, the athlete should throw the discus in a circle with the diameter of 2.50 meters, and the discus must fall within an angle line of 34.92 degrees to be effective.
When carrying out the discus training, there is the requirement to the angle of throwing, new student is when turning, the inconvenient angle of throwing carries out accurate control, the phenomenon of off tracking when throwing appears easily, if the balancing ability is not strong enough, will run out the specified circle when turning, the inefficacy appears easily, when carrying out the discus training, the coach only demonstrates the teaching, but the student can not be fine imitates, therefore, do not have a device to the trainer restriction, will influence the training of trainer, consequently, need design a discus training and solve above-mentioned problem with the stop device that turns.
Disclosure of Invention
The invention aims to solve the defects of the prior art and provides a turning limiting device for discus training.
The invention is realized by the following technical scheme:
the utility model provides a discus training is with stop device that turns, includes the bottom plate, fastening screw is installed to bottom plate right side symmetry, open in the bottom plate left side has the second guide slot, the inside second cover ring that has cup jointed of second guide slot, second cover ring upside fixed mounting has the bracing piece, it has first guide slot to open on the bracing piece, first guide slot is inside to have cup jointed first cover ring, first cover ring left side fixed mounting has the connecting rod, connecting rod left end fixed mounting has the holding ring, the inside fixed mounting of holding ring has the return spring, the inside fixed mounting of return spring has the gasbag.
Preferably, the balloon is of annular configuration.
Preferably, the first collar is a sliding fit with the first guide slot.
Preferably, the second collar is a sliding fit with the second guide slot.
Preferably, the length of the second guide groove is less than 1 meter.
Preferably, the return spring is made of steel.
Compared with the prior art, the invention has the beneficial effects that:
the invention can tighten the device on users with different fat and thin body for use by arranging the air bag, combines the arrangement of the return spring, further better limits the user when training, facilitates the user to accurately throw the discus and conveniently controls the throwing angle, adopts the muscle memory principle through the training, thereby enabling a student to accurately memorize the amplitude of the turning body, can sense whether the turning body is qualified or not by the user self due to the resistance of the return spring, conveniently and rapidly judges the time for throwing the discus, facilitates the user to slide up and down and back and forth by arranging the first guide groove and the second guide groove, avoids influencing the turning body of the user, reduces the obstruction to the training, facilitates the installation and the positioning of the device by arranging the fastening screw, further has certain stability and is reasonable in design, convenient operation, meets the requirement and is worth popularizing and using.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution:
the utility model provides a discus training is with stop device that turns, includes bottom plate 8, fastening screw 9 is installed to 8 right side symmetries of bottom plate, open in the left side of bottom plate 8 has second guide slot 7, second lantern ring 6 has been cup jointed to 7 inside of second guide slot, 6 upside fixed mounting of second lantern ring have bracing piece 4, it has first guide slot 5 to open on bracing piece 4, 5 inside first lantern rings 3 of having cup jointed of first guide slot, 3 left sides fixed mounting of first lantern rings have connecting rod 2, 2 left ends fixed mounting of connecting rod have holding ring 1, 1 inside fixed mounting of holding ring has return spring 10, the inside fixed mounting of return spring 10 has gasbag 11.
