Detailed description of the invention
Embodiment, as shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, a kind of device of hurdling alleviating collision pain, bag
Including base 1, base 1 is arranged over two grooves 11, and groove 11 has been inserted into support bar 2, and support bar 2 includes two bodies of rod 21,
The cross section of the body of rod 21 is arc-shaped, and the radian of the cross section arc of the body of rod 21 is 135 °；
The lower section of the body of rod 21 is provided with two the first jacks 211, and two the first jacks 211 have been inserted into rotating shaft 8, rotating shaft 8
Two ends are fixed on the cell wall of groove 11, and the body of rod 21 can rotate along rotating shaft 8；
The body of rod 21 be arranged over the second jack 212, when the body of rod 21 vertical level is arranged, the axle of the second jack 212
Line and plane-parallel, the axis crossing the second jack 212 does the vertical plane of horizontal plane, and this vertical plane divides the body of rod 21 equally；
Two bodies of rod 21 are internally formed a receiving portion 22, and receiving portion 22 is inserted into the adjusting rod 3 of cylinder, adjusting rod 3
Can move up and down along support bar 2；
Adjusting rod 3 is provided with several the 3rd jacks 31, and the spacing of adjacent 3rd jack 31 is equal, several the 3rd jacks
The axis of 31 is parallel to each other, the axis of several the 3rd jacks 31 at grade, the axis institute of several the 3rd jacks 31
Plane divide equally adjusting rod 3；
Support bar 2 and adjusting rod 3 are connected by fixing bar 5, and fixing bar 5 runs through two the second jacks 212 on support bar 2
With the 3rd jack 31 of adjusting rod 3, the two ends of fixing bar 5 are respectively sleeved on loop bar 6, and loop bar 6 can horizontally slip along fixing bar 5,
Being connected between loop bar 6 with fixing bar 5 and have compression spring 7, compression spring 7 is in extended state.
Two adjusting rods 3 be arranged over cross bar 4, the outside bag of cross bar 4 is provided with soft elastic material.
During use, base 1 is placed on runway, base 1 fixes two support bars 3, regulates adjusting rod 3
Highly, with fixing bar 5 and loop bar 6, support bar 2 is fixed, when carrying out hurdle campaign, when the lower limb of people encounters cross bar 4, give
4 one power of cross bar, now inclination freeed by adjusting rod 3, and under force, loop bar 6 moves to the direction away from support bar 2, this
Time adjusting rod 3 depart from support bar 2, the power that adjusting rod 3 departs from 2 need of support bar the least can complete, and decreases the resistance to people,
Adding cross tube 4 and be provided with soft elastic material, alleviate the pain that human body collision produces, compression spring 7 can be selected as required
Different elastic force, elastic force is the smaller the better in principle.
The above is the citing of this utility model preferred forms, and the part addressed the most in detail is this area
The common knowledge of those of ordinary skill.Protection domain of the present utility model is as the criterion with the content of claim, any based on this reality
