Description
Technical field
The utility model relates to a kind of sports movement apparatus, particularly relates to a kind of block.
Background technology
At present when school carries out start of a race training, frequent use block, because the pin of each student varies in size, height is different, the spacing of block clearance time two pedal is different, the pin shape that the start of a race scrunches is also different, and a therefore current block can not be applicable to the off training requirement of all students, and the scope of application is little.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the scope of application, adjustable foot pedal spacing and the block scrunching radian.
The technical solution of the utility model is a kind of block, it comprises base plate 1, it is characterized in that: the left and right sides, bottom of described base plate 1 is respectively equipped with chute 2, being provided with by fastening bearing pin 3 in described chute 2 can along the supporting plate 4 of described fastening bearing pin 3 horizontal deflection, described supporting plate 4 is provided with pedal 5, described pedal 5 comprises and is arranged on center thread spindle 6, described thread spindle 6 is bolted with nut 7, the outer wall of described nut 7 is evenly equipped with three connecting rods 8, the other end of described connecting rod 8 respectively with one the inner side of leg-of-mutton three gripper shoes 9 hinged, the outside of three described gripper shoes 9 is set with plastic anti-skid cover 11.
The technical solution of the utility model can also be that the rear and front end, bottom of described base plate 1 is respectively equipped with slipmat 10.
The technical solution of the utility model can also be that the gripper shoe 9 bottom described pedal 5 is fixed on described supporting plate 4 by bolt or rivet together with plastic anti-skid cover 11.
The beneficial effects of the utility model are by being respectively equipped with chute 2 in the left and right sides, bottom of described base plate 1, being provided with by fastening bearing pin 3 in described chute 2 can along the supporting plate 4 of described fastening bearing pin 3 horizontal deflection, described supporting plate 4 is provided with pedal 5, described pedal 5 comprises and is arranged on center thread spindle 6, described thread spindle 6 is bolted with nut 7, the outer wall of described nut 7 is evenly equipped with three connecting rods 8, the other end of described connecting rod 8 respectively with one the inner side of leg-of-mutton three gripper shoes 9 hinged, the outside of three described gripper shoes 9 is set with plastic anti-skid cover 11, during use, supporting plate 4 is moved to correct position and supporting plate 4 the is taken up left and right sides that solid bearing pin 3 deflects to base plate 1 along chute 2, then fixed by fastening bearing pin 3, student's both feet that the start of a race is trained are placed on pedal 5, and by rotating threaded shaft 6 make the nut 7 on thread spindle 6 threadingly axle 6 move, thus drive three uniform connecting rods 8 on nut 7 outer wall to move, due to connecting rod 8 the other end respectively with one the inner side of leg-of-mutton three gripper shoes 9 hinged, thus drive three gripper shoes 9 to move to center, again because the outside of three described gripper shoes 9 is set with plastic anti-skid cover 11, along with the plastic anti-skid cover 11 that rotarily drives of thread spindle 6 produces to internal strain, namely formed on the foot-operated face of pedal 5 and different scrunch radian, thus adapt to the off requirement of different off training of students, achieve structure simple, the scope of application, adjustable foot pedal spacing and the effect scrunching radian.
