Embodiment 2

[0032] The present invention is equipped with a moving part, which can move the measuring device to the place to be measured by pushing the base 4, and at the same time, a positioning device is provided on the universal roller 7, so that the entire measuring device can be positioned when it moves to a suitable position.

[0033] When the football is thrown into the storage basket 1, the buffering part may cause an error when it falls due to the impact force, and the buffering spring 12 of the buffering part can reduce the error.

[0034] The throwing part is set to control whether it is in the throwing state by rotating the damping rotating shaft 2. When it is in the non-throwing state, the support plate 3 is in the intercepting state, and when it is in the throwing state, the support plate 3 is opened.

[0035] The height adjustment part is set, which can be independently adjusted and selected through the telescopic rod 8. The height during measurement can obtain different rebou...

Abstract

The invention relates to a technique for football bounce rate measurement in a football field, in particular to a mechanical system for a football bounce rate measurement device for the football field. The mechanical system comprises a football throwing portion, a buffering portion, a moving portion and a height adjusting portion. The measurement device can be moved to a measurement requiring position through pushing of a base, and buffer springs of the buffering portion can reduce errors; a telescopic rod of the adjusting portion is connected with a storage basket through a fixing frame whichis a triangular fixing frame high in stability, so that a stable state of the storage basket in a measurement process can be guaranteed; by a counterweight device arranged on the moving portion, thestorage basket is prevented from toppling, and force balance is achieved; a height indicator calculates the bounce rate according to the football falling speed and bounce time and sends measurement data to a remote end through a central processing unit. The mechanical system is simple in structure, convenient and quick in height adjustment, convenient to move and high in creativeness and has an intelligent measurement function.

Description

technical field [0001] The invention relates to a technique for measuring the rebound rate of footballs in a football field, in particular to a mechanical system of a device for measuring the rebound rate of footballs in a football field. Background technique [0002] Football originated in the State of Qi during the Warring States period in ancient China. At that time, football was called "Cuju". Cuju was a means of training soldiers in the Han Dynasty, and a relatively complete system was established. If a court is specially set up, it is defined as a rectangle in the east-west direction, and there are six symmetrical "Ju domains" at each end, also called "Ju rooms", each guarded by one person. The site is surrounded by walls. The game is divided into two teams, each with offense and defense, and the winner is determined by the number of kicks into the opponent's court. The bounce rate of football, that is, the percentage of the rebound height of the football vertically ...
