Abstract
The utility model relates to a kind of Single-post gravitational auto-return high jump stand.The technical scheme adopted is, single-column is made up of movable post and fixed leg, and movable column sleeve is contained on fixed leg and can moves up and down, and 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 has the scale of display height.Cross bar is L-type, one end is unsettled, and the other end has cross bar connecting lever, and the stripe shape shaft set in the middle of cross bar connecting lever is in cross bar connecting lever support screw, movable column sleeve is contained on fixed leg and can be elevated so as to regulating cross bar height, movable post is provided with height holding screw and is convenient to fixing single-column.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.Beneficial effect is province's material, automatically resets effective, simple and beautiful structure.
Description
Technical field
The utility model relates to sports equipment, especially a kind of Single-post gravitational auto-return high jump stand.
Background technology
In prior art, existing jumping stand is all dual-gripper post, compares consumptive material, mobile also cumbersome, and the cross bar of prior art does not mostly possess automatically reset function simultaneously, 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 gravitational auto-return high jump stand that the utility model provides a kind of province material, is particularly suitable for training, imparts knowledge to students.
The technical scheme that the utility model adopts 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, counterweight is provided with below cross bar connecting lever, 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 of counterweight gravity when sportsman touches cross bar.
The beneficial effects of the utility model are province's materials, automatically reset effective, simple and beautiful structure.
Accompanying drawing illustrates that the utility model is described in further detail below in conjunction with drawings and Examples.
