Abstract
A ground ball rebound tester comprises a straight bar, a supporting seat which is connected with the lower end of the straight bar in to a whole and a fixing mechanism which is connected with the straight bar and used to fix test balls. The utility model is characterized in that: the fixing mechanism used to fix test balls comprises a cross bar, an outer vertical bar, an inner vertical bar, a fixing bar, a reset elastic element and a haulage cable; the outer vertical bar is fixed on the outer end of the cross bar; one end of the inner vertical bar is pivotally connected with the inner end of the cross bar; the fixing bar is fixed on the cross bar between the inner vertical bar and the straight bar; the reset elastic element is fixed between the inner vertical bar and the fixing bar; one end of the haulage cable is connected with the other end of the inner vertical bar. The utility model is simple in structure, needs no power, and can conveniently test the grounds without power, such as the sports or athletic grounds in lack of power supply.
Description
Technical field
The utility model relates to a kind of proving installation of testing the ball bounce-back rate on ground.
Background technology
Ground is an important indicator that influences ball game and sports in the face of the bounce of ball, especially for artificial ground, more needs a kind of ground ball bounce-back proving installation, to guarantee normally carrying out of ball sports activity.
The present ground ball proving installation that vertically rebounds, supporting seat that comprises straight-bar, fuses with the bottom of straight-bar and the fixed mechanism that is used for fixing test ball, said reference test bar is provided with inhales ball mechanism, ball is inhaled the height of stipulating by power, then ball is discharged, freely land, to detect the height of its bounce-back.Present device needs power, therefore, for there not being power, as lacks the sports or the athletic ground of power supply, then can't test, and it is very inconvenient to use.
Summary of the invention
The purpose of this utility model is a kind of ground ball of design proving installation that vertically rebounds, to overcome the above-mentioned defective that prior art exists.
A kind of ground ball of the present utility model proving installation that vertically rebounds, the supporting seat that comprises straight-bar, fuses with the bottom of straight-bar and be connected the fixed mechanism that is used for fixing test ball on the straight-bar, it is characterized in that the said fixed mechanism that is used for fixing test ball comprises cross bar, outer montant, interior montant, fixed bar, reseting elastic element and dragrope;
Outer montant is fixed on the outer end of cross bar, one end of interior montant is by the rotating the inner that is connected cross bar of pin, on the cross bar in fixed bar is fixed between montant and the straight-bar, between montant and the fixed bar, an end of said dragrope was connected with the other end of interior montant in reseting elastic element was fixed on.
The utility model is to use like this, and ball is placed between outer montant and the interior montant, and it is fixing to rely on reseting elastic element that ball chuck is lived, and spurs dragrope then, and montant in dragrope drives can discharge ball and land, thereby detects its bounce-back height.
The utility model has the advantages that very significantly, simple in structure, do not need power, for there not being power, as lack the sports or the athletic ground of power supply, also can test easily.
