Abstract
The invention relates to a single-column spring-type automatic resetting jumping stand. The invention adopts the technical scheme as follows: a single column consists of a movable column and a fixed column; the movable column sleeves the fixed column and can move up and down; a cross rod is movably connected with the movable column through a cross rod crank arm; the height of the cross rod is adjusted by adjusting the movable column; height scales are arranged on the fixed column; the cross rod is L-shaped, one end of the cross rod is suspended in air, and the cross rod crank arm is arranged at the other end of the cross rod; a bar-shaped rotating shaft in the middle of the cross rod crank arm sleeves a cross rod crank arm supporting screw; the movable column sleeves the fixed column and can rise and fall so as to adjust the height of the cross rod; a height tightening screw is arranged on the movable column so as to fix the single column. When an athlete touches the cross rod, the cross rod generates displacement, and when an external force disappears, the cross rod can automatically reset under the action of a spring tension. The single-column spring-type automatic resetting jumping stand has the beneficial effects of material conservation, good automatic resetting effect, simple structure and attractive appearance.
Description
Technical field
The present invention relates to sports equipment, especially a kind of Single-post spring-type auto-return high jump stand.
Background technology
In prior art, existing jumping stand is all dual-gripper post, compares consumptive material, and mobile cumbersome, the cross bar of prior art does not mostly possess automatically reset function yet, if just more inconvenient as teaching and training.
Summary of the invention
In order to overcome the deficiencies in the prior art, the Single-post spring-type auto-return high jump stand that the invention provides a kind of province material, be particularly suitable for training, impart knowledge to students.
The technical solution adopted in the present invention is, jumping stand is by base, single-column, the critical pieces such as cross bar are formed, it is characterized in that: single-column is made up of movable post and fixed leg, movable column sleeve is contained on fixed leg and can moves up and down, cross bar is flexibly connected with movable post by cross bar connecting lever, adjustment activity post just have adjusted the height of cross bar, fixed leg there is the scale of display height, cross bar is L-type, one end is unsettled, the other end has cross bar connecting lever, bar shaped rotating shaft is provided with in the middle of cross bar connecting lever, this bar shaped rotating shaft is parallel with cross bar, bar shaped shaft set in the cross bar connecting lever support screw parallel with cross bar to ensure the parallel of cross bar, the free end cap nut back of the body is tight in case cross bar connecting lever comes off and makes it rotate flexibly, spring is provided with below cross bar connecting lever, lower spring end has spring tension adjusting bolt, to ensure that cross bar connecting lever in the quiescent state in vertical state, movable post is hollow shape, being sleeved on fixed leg to be elevated so as to regulating cross bar height, movable post is provided with height holding screw, so that fixing movable post, fixed leg is fixedly connected with base.
Cross beam displacement can be caused, when outer active force disappearance rear transverse rod can automatically reset under the effect at spring tension when sportsman touches cross bar.
The invention has the beneficial effects as follows province's material, automatically reset effective, simple and beautiful structure.
Accompanying drawing illustrates that the invention will be further described below in conjunction with drawings and Examples.
