Description

Football pitch arc ball trainer

Technical Field

The invention relates to the field of football training devices, in particular to a football arc ball training device.

Background

In modern football, the arc ball is an important means for tactical ingenious matching or direct shooting scoring by bypassing a defense barrier in a match due to the technical characteristic that the track of the arc ball is bent in the running process, and the arc ball is a technology which is desired to be mastered by wide football players and football lovers; in recent years, regarding the principle and technical key of the arc ball, domestic and foreign experts apply physical knowledge to analyze, and advanced information technology means are adopted to analyze the technical parameters required by the arc ball, so that the technical characteristics and rules of the arc ball are successfully dataized.

The traditional arc ball teaching training is that a practitioner repeatedly flies out the ball kick, and can play the ball, observe the ball flying track and gradually correct the ball to improve the accuracy so as to master the arc ball technology; the ball is required to fly to generate an arc line, the flying distance is generally more than ten meters, and the ball rolling distance is added, so that a practitioner can kick out the ball for tens of meters every time of practice, a great deal of physical strength and time are required for picking up the ball back and forth, and the efficiency of practicing the arc line ball is seriously affected.

The Robert D-Orer is improved on the basis of the patent with the publication of CN 102648030B, and the invention patent with the publication number of CN 106890439A is applied for, and discloses a kicking training device, which comprises a support rod seat and a rotating arm arranged on the support rod seat, wherein the rotating arm is connected with a ball; both schemes are to fixedly connect the ball with the rotating arm, and the defect is that: 1. the ball can only generate a very single rotation through the ball rotating device at the upper end of the rotating arm, and the multidirectional combined rotation of the arc ball in the flying process can not be realized; 2. the physical properties of the ball are changed, so that the feel of the foot is distorted during exercise; in addition, the rotating arm is also relatively fixedly connected with the upright post, the ball still can only move in a circular track during practice, the stress points of the ball during practice can only be two side surfaces of the ball, and the practice of the arc ball cannot be met.

Disclosure of Invention

The technical problem to be solved by the invention is to provide the football arc ball training device, which not only can avoid physical and time consumption caused by repeated ball picking, but also can realize multi-direction combined rotation and movement of the ball, and can realize multi-point ball hitting, thereby meeting the training of arc balls.

The invention is realized by the following technical scheme:

the utility model provides a football pitch arc ball trainer, includes training ball, still includes spacing ring, slip telescopic link and base, spacing ring limit portion fixed connection is in training ball, leaves the clearance between middle part and the training ball, sliding connection's cambered surface board in the clearance is installed to the front end of slip telescopic link, and the end passes through joint bearing transverse connection in the base.

According to the invention, the outer cambered surface of the cambered surface plate is detachably arranged at the front end of the sliding telescopic rod, so that the cambered surface plate, the training ball or the limiting ring can be conveniently disassembled, assembled and maintained when damaged.

According to the invention, the base is in a step shape, the ball seat of the knuckle bearing is arranged at the junction of the steps, and the opening is inclined upwards; the sliding telescopic rod is transversely placed on the lower step, and the bottom of the training ball is flush with the bottom surface of the lower step; the lower step bears the weight of the sliding telescopic rod, the arc panel and other mechanisms, so that the training ball is not applied with external force in a static state, the natural placing state of the training ball is simulated, and the kicking training is more real.

The sliding telescopic rod is composed of a sleeve and a core rod which are coaxial, the tail end of the core rod is connected with the inner cavity of the sleeve in a sliding way, and the front end of the core rod is provided with an arc panel; the tail end of the sleeve is connected with the ball head of the joint bearing, and a reset spring is arranged between the tail end of the inner cavity of the sleeve and the tail end of the core rod; the impact force received by the training ball is absorbed and released through the reset spring, and the deformation process of the reset spring is closer to the training ball, so that the reality of the foot feeling is further improved.

According to the invention, the upper step and the lower step of the base are fixedly connected through the bolts after being laminated, and the upper part and the lower part of the ball seat are respectively positioned on the upper step and the lower step, so that the ball seat is easy to detach and assemble and is convenient to maintain.

According to the invention, the bottom of the base is provided with the folding castor and/or the anti-skid mechanism, the folding castor is convenient for moving the base in a non-training time period, and the anti-skid mechanism can provide stronger resistance during training, so that the base is more stable, and the impact movement is prevented from influencing the training effect.

In a still further aspect of the present invention, the anti-slip mechanism is a spike.

Compared with the prior art, the invention has the advantages that:

the cambered surface board sliding connection makes the training ball can carry out circumference rotation for the slip telescopic link in spacing ring and the clearance that training ball surface formed, and the slip telescopic link both can stretch out and draw back, can regard joint bearing as the fulcrum to carry out arbitrary removal in a certain range again, synthesizes down, has realized the multidirectional combination rotation of training ball, removal, can also the multiple spot ball of hitting, satisfies the exercise of arc ball, can keep the foot sense of training ball moreover.
