Description

Technical Field

[0001] The invention relates to a golf swing trainer, in particular to a device for fixing a golf trainer's standard standing posture and stabilizing a swing and hitting trajectory. Technical Background

[0002] Golf is a good outdoor sport, and most people who play golf are amateurs, but it is also a very difficult ball sport. To learn to play golf well, you need to practice swinging for a long time under the guidance of a professional coach. You need to learn to master the correct standing posture and complete swing movements, including: backswing, downswing, and backswing, a total of three steps. In addition, during the swing, the head needs to remain stable and cannot be offset with the rotation of the shoulders. The waist needs to be rotated in place and cannot fall sideways due to the backswing process.

[0003] In order to help golfers stabilize their swing movements, some golf swing training devices are available on the market. The currently known golf swing training device is provided for the practitioner to hold the training stick and practice swinging in the air along the circular track. The following problems exist in the practice of swinging in the air:

[0004] 1. The 360-degree circular trajectory does not conform to the actual swing trajectory. The reason is that when the practice club is swung to the shoulder, its inertia will subconsciously slide along the circular trajectory, causing the body to be carried backward by inertia and form an incorrect back-to-back action.

[0005] 2. Lack of control over the backswing, because if the backswing is too high, the body and head will rotate with it, which will result in poor ball hitting.

[0006] 3. Swinging with a practice stick in the air cannot determine the correctness of the swing action.

[0007] Chinese patent application No. 200680056595.6 discloses "an inflatable golf swing practice device", comprising: an inflatable track track and an adjustment rod, the inflatable track track having a track curvature of a swing running track, and being enclosed by a closed capsule made of an inflatable hollow elastic material; the adjustment rod comprises two front adjustment rods and two rear adjustment rods; the two front adjustment rods are arranged at the lower part of the inflatable track track for adjusting the height and angle of the inflatable track track; the two rear adjustment rods are arranged in the middle part of the inflatable track track for adjusting the angle between the plane of the inflatable track track and the horizontal plane.

[0008] Chinese patent application No. 201720295078.x discloses a "golf swing trainer", comprising: a frame, including a bottom and a side; a stance limiting assembly, installed on one side of the bottom, used to limit the stance of the practitioner; a slide rail assembly, movably installed on the side, having a curved section; and a practice rod assembly, slidably installed on the curved section of the slide rail assembly. The utility model adopting the above structure can adjust the position of the slide rail assembly for different practitioners, so as to adapt to practitioners of different body shapes, and the adjustment is convenient, fast, flexible and reliable. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a golf swing trainer which can effectively fix the standard action of swinging and hitting the ball.

[0010] The golf swing trainer of the present invention is composed of a golf club with a rotating roller sleeve, a swing track, a support rod, a bracket and a base. The swing track is composed of a circular arc track and a turning slideway. The circular arc track and the turning slideway are a connected whole. A lane-dividing fixture is arranged 65-75 cm to the right of the intersection of the upper part of the circular arc track and the support rod. One side of the lane-dividing fixture is fixedly connected to the circular arc track, and the other side is fixedly connected to the turning slideway. The turning slideway is the part behind the lane-dividing fixture and is 60-80 cm long. A swing height limit block is arranged above the circular arc track. The swing height limit block is fixed at 3-7 cm to the left of the intersection of the upper part of the arc track and the support rod. The lower end of the arc track is fixed on the bracket, and the upper end is supported on the support rod to form a swing track tilted backward; there are two brackets, which are located at one-quarter to one-third of the distance from the front edge of the base, symmetrically arranged, and fixedly connected to the base. The lower end of the support rod is fixed at the center point of the rear edge of the base, and consists of two upper and lower circular tubes, wherein the lower tube is thicker and the upper tube is thinner. The upper tube is inserted into the lower tube and can slide therein. There is a locking sleeve on the upper mouth of the lower tube. The support rod is provided with an adjustment part, a head fixing rod, and a waist fixing rod.

[0011] The radius of the circular arc track is 90 cm-110 cm.

[0012] The radial distance X between the end of the turning slideway and the arc track is 10-20 cm, and the vertical height Y between the end of the turning slideway and the arc track is 20-30 cm.

[0013] The lane-dividing fixture has a large and small thickness, the large end is 5.5-6.2 cm, the small end is 2.8-3.3 cm, the distance between the large end end face and the small end end face is 10-15 cm, the thickness and distance of the lane-dividing fixture determine the distance between the arc track and the turning taxiway, one side of the lane-dividing fixture in the thickness direction is fixedly connected to the arc track, and the other side is fixedly connected to the turning taxiway. The large and small thickness design of the lane-dividing fixture makes the distance between the arc track and the turning taxiway gradually increase.

[0014] The rotating roller sleeve of the golf club consists of a roller sleeve, a bearing outer sleeve, a bearing, a shaft fixing sleeve and a shaft locking nut. The rotating roller sleeve is sleeved on the shaft of the golf club near the hitting end and is locked and fixed from both ends by the shaft locking nuts.

[0015] The golf swing trainer of the present invention has a rotatable roller sleeve on the golf club. When the golf club swings up and down along the swing track, it is the roller sleeve that rotates, thereby avoiding hard friction between the golf club and the swing track. The swing height limit block defines the swing height, and the steering slideway defines the finishing track, so that the golf club can form a standard finishing action after sliding out of the steering slideway. Together with the head and waist fixing parts, the whole enables the golf practitioner to obtain a standard fixed swing height, swing track and finishing action. The practitioner can form a standard standing posture under the restriction of the fixed rod, and the head will not shift with the rotation of the shoulders when swinging up. A steering pulley is installed under the bottom plate of the trainer, and the practitioner can change different hitting directions as needed.

[0016] The golf swing trainer of the present invention not only overcomes the disadvantage of swinging the practice stick in the air along a circle, but also allows the golfer to directly practice hitting the ball, and naturally forms a standard, correct and stable swing action during the swing and hitting practice.
