Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a field diameter training is with springboard, includes two bottom plates 1, fixedly connected with connecting plate 2 between two bottom plates 1, and 1 one end of two bottom plates articulates there is same panel 3, and first spring 4 of fixedly connected with respectively, second spring 5 between two bottom plates 1 and the panel 3, 1 bottom difference fixedly connected with of two bottom plates is trapezoidal base 6.

Trapezoidal base 6 can increase the area of contact of this track and field training with springboard and ground for it is more firm, trapezoidal base 6 bottom is provided with anti-skidding stripe 601, anti-skidding stripe 601 can increase the frictional force between trapezoidal base 6 and the ground, prevent that this track and field training from sliding with springboard, set up notch 602 near first spring 4 on trapezoidal base 6, the setting of notch 602 is the installation of avoiding trapezoidal base 6 to obstruct round bar 7.

Fixedly connected with one corresponds round bar 7 of two notches 602 between two bottom plates 1, six two liang of a set of limit ring 9 has been cup jointed on the round bar 7, it has three turning block 8 that are located between two limit ring 9 of every group to rotate on the round bar 7, it can prevent that turning block 8 from sliding on round bar 7 to set up limit ring 9, one side fixedly connected with third spring 10 of turning block 8, each turning block 8 is with the round cross section symmetric distribution in the middle of round bar 7 is positive, make the elasticity that each third spring 10 produced to panel 3 balanced, through setting up sliding block 8 and third spring 10, can selectively rotate third spring 10, make third spring 10 and supporting panel 3 or not supporting panel 3, thereby adjust the resilience force that panel 3 received when being trampled and pushing down.

One end fixedly connected with rectangular block 11 that turning block 8 was kept away from to third spring 10, panel 3 lower surface fixedly connected with corresponds rectangular block 11's rectangular frame 12, the inside rectangle through-hole size of rectangular frame 12 and rectangular block 11's size looks adaptation, rectangular block 11 is located rectangular frame 12, setting through rectangular block 11 and rectangular frame 12, can make the third spring 10 top better agree with fixedly with panel 3, prevent to push down in-process third spring 10 at panel 3 and slide the bending because of the top by a wide margin, and the non-compression, lead to unable normal resilience force of panel 3 production.

The working principle is as follows: when in use, the trapezoidal base 6 is contacted with the ground, the anti-skid stripes 601 can increase the friction force between the trapezoidal base 6 and the ground, then selectively rotate and adjust the number of the third springs 10 according to the jumping elasticity needed by the track and field training athletes, so that the third springs 10 are clamped into the rectangular frame 12 through the rectangular blocks 11 to support the panel 3, when the panel 3 is not supported by the third springs 10, the springboard for track and field training only depends on the first spring 4 and the second spring 5 to generate elastic force to the panel 3, at the moment, the resilience force received by the panel 3 after being stepped on is the minimum, when the middle third spring 10 is rotated to support the panel 3, the resilience force applied to the panel 3 after being pressed increases, when the other two symmetrical third springs 10 are rotated again to support the panel 3, the resilience force applied to the panel 3 after being stepped on is increased again, so that the springboard for track and field training can provide springing elasticity with different requirements.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
