Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the top view of breast board in the utility model.
Coding in figure is respectively: 1 is top board, and 2 is groove, and 3 is torsion spring, and 4 is baffle plate, and 5 is slot, and 6 is the first railing, and 7 is base plate, and 8 is axostylus axostyle, and 9 is locating hole, and 10 is slide block, and 11 is fixed head, and 12 is latch, and 13 is portable plate, and 14 is the second railing.
Detailed description of the invention
As depicted in figs. 1 and 2, this track and field safe hurdles, comprise the first railing 6 and the second railing 14, top board 1 and a base plate 7 is provided with inside the upper and lower end face of described first railing 6 and the second railing 14, one cylindrical axostylus axostyle 8 is all installed between described top board 1 and base plate 7, on axostylus axostyle 8, all a slide block 10 is installed in activity, a groove 2 is provided with from top to down in the middle of described slide block 10, the width of described groove 2 is greater than the diameter of axostylus axostyle 8, the end face outside of described axostylus axostyle 8 offers more than one locating hole 9 from top to down, the its right end face of described slide block 10 offers a pin hole, pin hole and locating hole are provided with a latch 12, the diameter of described locating hole 9 is greater than the diameter of pin hole, the medial surface of described first railing 6 and the second railing 14 offers more than one slot 5, the lateral surface of described slide block 10 is provided with a groove, one baffle plate 4 is installed in described groove, the upper and lower side of described baffle plate 4 is provided with a connecting axle, described connecting axle is all installed a torsion spring 3, one end of described baffle plate 4 is installed in slot 5, the medial surface of described slide block 10 all installs a breast board.
Wherein, breast board comprises fixed head 11 and a portable plate 13, one end of described fixed head 11 is fixedly connected with slide block 10, described fixed head 11 is just provided with a chute to portable plate 13 1 side, described portable plate 13 is just provided with a connector to chute side, and described portable plate 13 is installed in the chute of fixed head 11 by connector.
