The touching instruction unit 303 of the length direction of flat bar 302, the touching instruction unit 303 can be done perpendicular along the axis of the horizon bar 302
Straight Plane Rotation;The abutment end of two horizon bars 302 is provided with the second magnetic part, and two horizon bars 302 pass through institute
The second magnetic part is stated, two horizon bars 302 are to fix by screw by the absorption cooperation of the second magnetic part, the second magnetic part
In two 302 ends of horizon bar and opposite polarity two blocks of magnet, by being fixed for two 302 ends of horizon bar, can mention
The stability of 3 position of bar structure when high hurdles rack uses;
The touching instruction unit 303 includes cricoid lantern ring 303a, and the lantern ring 303a inner sleeve is equipped with bearing 303b, the set
Ring 303a is rotatably assorted by bearing 303b with the horizon bar 302, on the circumferential symmetrical two sides outer wall of the lantern ring 303a
Be provided with two bow strips 303, when hurdling trained, bow strip 303 is vertically arranged, during user hurdles, if body with
Bow strip 303 contacts, and bow strip 303 drives lantern ring 303a rotation, that is, represents jumping height deficiency, or need to adjust user
Jumping height;
The bow strip 303 forms slot 303d far from the one end the lantern ring 303a, and setting is flexible in the slot 303d
The lengthening part 303e of materials for support;The lengthening part 303e is the rubber strip being interference fitted with the slot 303d, by connecing
After the end touch article 303c is inserted into rubber strip and is set as vertical state together with bow strip 303c, the highest of bar structure 3 can be improved
The height of point, adapts to the practice demand of different users.
Using the above structure, there are two types of use states altogether for this hurdles rack, the first is as shown in figure 8, using a chassis 1, one
Column 2 and a bar structure 3 composition can carry out in use, the body of the movable end of cross bar towards user are lifted leg side across leg
Practice can force down the height of leg, until leg according to the height of horizon bar 302 and touching instruction unit 303 during practice
Portion is contacted with touching instruction unit 303, the technical movements of leg corresponding position can be adjusted by observation touch position, with
Reach and complete to hurdle movement under the premise of lowering the center of gravity as far as possible, in this case in use, leg is contacted with bar structure 3 touches
When hitting, bar structure 3 is rotated along 2 top of column, will not be toppled over 2 band of column, safety is good.
Second of use state as shown in figure 9, be assembled state, by touch instruction unit 303 two bow strip 303c it is equal
It adjusts to vertical state, at this point, the top bow strip 303c in eminence is the highest point of hurdles rack, in practice process of hurdling
In, if the jumping height of body is insufficient, the touching instruction unit 303 that body will drive corresponding position rotates, to help to use
Technical movements are adjusted in person, prevent body from contacting with bar structure 3, convenient for users to technical movements are adjusted, mention
High training effect.
It is easy to assembly by separation design, and be readily transported;It is used by separating hurdles rack, it will be rotatable horizontal
Rod structure 3 then carries out across leg training towards the preceding lift leg side of human body, after bar structure 3 is touched in leg, can pass through cross bar edge
The rotation of column 2 prevents column 2 and chassis 1 from toppling over, and safety is good;
By the way that the touching instruction unit 303 that can be rotated along perpendicular, in training process of hurdling, body are arranged on bar structure 3
Body is when leaping bar structure 3, after body contact with touching instruction unit 303, can touch instruction unit 303 and rotate, can be to hurdling
The contact position of body and bar structure 3 is observed in journey, convenient for users to being directed to touch position to commencing height and technology
Movement carries out corresponding adjusting, to improve training effect.
As shown in Fig. 2, for the ease of the vertical state for making bow strip 303c quickly restore initial, the bow strip 303c
End be additionally provided with magnetic magnetic sheet 303f;The inside of the column 2 is additionally provided with hinged seat 4, which can
The iron 5 overturn above and below is hinged, and the length of the iron 5 is identical as the length of horizon bar 302;And iron 5 rotates to horizontal position
When positioned at the underface of bow strip 303c vertical state.The underface of the hinged seat 4 is additionally provided with the magnetic for adsorbing iron 5
Seat 6.When specific operation, it holds iron 5 and rotates it to horizontal position, then stir bow strip 303c, when magnetic sheet 303f rotates
When to 5 corresponding position of iron, due to the adsorption capacity of magnetic sheet 303f and iron 5, bow strip 303f can be made quickly to be in
Vertical state, use are very convenient.When bow strip 303c is restored to vertical state, overturning iron 5 is sagging, makes under iron 5
End is contacted with magnetic absorbing seat 6, so as to fixed iron 5.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
