Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing 1-2.
Embodiment: a kind of physical education elastic force device for high jump, as shown in Figure 1, including two vertically arranged fixations
Bar 1,1 bottom of fixed link are fixedly connected with the fixing seat 11 being placed on the ground.Fixed link 1 is equipped with horizontally disposed supporting table
12,12 lower surface of supporting table is fixedly connected with the lantern ring 13 being socketed with fixed link 1, and lantern ring 13 is equipped with to be supported on the outside of fixed link 1
The fixing bolt 14 of touching.
As shown in Figures 1 and 2, cross bar 2 is equipped between two supporting tables 12, cross bar 2 includes two support side rods 22 and position
In the intermediate bar 21 that two support between side rod 22, side rod 22 is supported to be placed on corresponding supporting table 12 far from the end of intermediate bar 21
On.Side rod 22 is supported to be equipped with rotation chamber 25 close to the end of intermediate bar 21, rotation 25 inner wall of chamber is fixedly connected with rotation axis 27, in
Between the end of bar 21 be equipped with the rotation section 26 that is rotatablely connected with rotation axis 27, during cross bar 2 is placed in supporting table 12,
Rotation axis 27 is set to keep vertically arranged；Using intermediate bar 21 and two support side rods 22, colliding cross bar 2 in trainer makes cross bar 2
The case where after falling, support side rod 22 and intermediate bar 21 are relatively rotated, and are avoided the fracture of cross bar 2 and are stabbed trainer.
As shown in Fig. 2, there are two the first confined planes 28 close to the end symmetric setting of rotation chamber 25 for support side rod 22, it is intermediate
There are two the second confined planes 29 contradicted with corresponding first confined planes 28 for end symmetric setting of the bar 21 close to rotation section 26；It utilizes
First confined planes 28 and the second confined planes 29 contradict, and support side rod 22 and intermediate bar 21 is avoided to relatively rotate excessively and weigh training wounded
The case where person, occurs, and improves the protective performance of device for high jump.
