Technical Field

The invention relates to the field of physical education, in particular to an archery teaching auxiliary trainer.

Background

At present, a rubber strip is used for simulating a dispenser in archery teaching so as to solve the problems of leaning position of archery action and correction of dispensing action. Present archery teaching auxiliary equipment does not consider the beginner to accomplish a plurality of problems that need solve in the action, for example: a correct standing position; correct forearm boom movement; correct bowstring rest position; correct dispensing action; self-observation after completion of the action, etc. Therefore, a new solution is now needed.

Disclosure of Invention

In order to solve the problems, the invention discloses an archery teaching auxiliary exerciser which can effectively solve the difficulty in basic exercise of archery teaching, improve teaching efficiency, enable the archery basic action to be really realized under the real bow scene, and is simple in integral structure, convenient to operate and low in preparation cost.

In order to achieve the above purpose, the invention provides the following technical scheme: the utility model provides an archery teaching auxiliary exercise ware, includes the vertical pillar that is equipped with in base frame, base frame upper end, the bow body that is equipped with on the pillar and the observation mirror that is equipped with by side of base frame position.

The base frame is a rectangular frame formed by mutually splicing a first rod piece, a second rod piece, a third rod piece and a fourth rod piece, a pillar base is vertically and fixedly arranged in the middle of the upper end of the first rod piece, a marking line is connected between the first rod piece and the third rod piece, a foot limiting piece is movably arranged on the marking line in a penetrating mode, first positioning screw holes are vertically and uniformly formed in the outer end wall of the top side of the pillar, a cylindrical positioning frame is movably sleeved on the outer side of the top end of the pillar, a second positioning screw hole is formed in the outer end wall of the cylindrical positioning frame, and a positioning screw is screwed into the second positioning screw hole. The first rod piece, the second rod piece, the third rod piece and the fourth rod piece can be connected with each other through bolt screw holes, welding and other modes, and the positioning screw can penetrate through the second positioning screw hole and be screwed into the first positioning screw hole.

As an improvement of the invention, a supporting seat is arranged at the lower end of the observation mirror, a camera bracket is arranged at the upper end of the observation mirror, central line marking holes are respectively formed in the middle parts of the corresponding ends of the first rod piece and the third rod piece, the marking lines are arranged between the central line marking holes, the number of the foot limiting pieces is two, the pillar base is in a hollow cylindrical shape, the top end of the pillar base is in an opening design, the cross section of the pillar is circular, the caliber of the inner end of the pillar base is larger than the diameter of the outer end of the cross section of the pillar, and a stop block is fixedly sleeved below the position of a first positioning screw hole which is uniformly distributed at the outer part of the upper end of. The camera shooting support is used for placing and supporting machines with camera shooting and recording functions, such as mobile phones, cameras and the like, the foot limiting piece can movably move along the length direction of the marking line, and the bottom end part of the support column can be inserted into the support column base.

As an improvement of the invention, the bow body comprises a bow handle, fixed bow arms respectively arranged at two side ends of the bow handle in the length direction, movable bow arms respectively hinged on the fixed bow arms, springs respectively arranged between the movable bow arms and the fixed bow arms, and bow strings arranged between the non-hinged end parts of the movable bow arms, wherein the bow handle is fixedly arranged outside the cylindrical positioning frame. Bowstring and marking line can be made of nylon ropes wound with each other, and the spring is detachably mounted and is convenient to replace.

As an improvement of the invention, the fixed bow arm is fixedly connected with the bow handle, the fixed bow arm is in a V shape, one end part of each movable bow arm is hinged with the end part of the tip end of the fixed bow arm, and springs are respectively arranged between the end part of the non-hinged end of the movable bow arm and the end part of the non-fixed end of the fixed bow arm.

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

1. through the design of the marking line and the foot limiting sheet, the error of the standing position of the two feet when the practicer arches is corrected;

2. the bow body is fixedly designed, and a pivot is provided for the rotating arm of the forearm, so that the rotating arm is convenient to rotate;

3. through the observation mirror and the camera or the camera recording instrument such as the mobile phone arranged on the camera bracket, the trainee can clearly observe whether the action leaning position is correct or not;

4. the bow spring can be designed to be empty for an unlimited time, and the real archery feeling can be realized;

5. the bow with different tensions can be simulated by adjusting the spring so as to adapt to exercisers with different forces;

6. whether the cylindrical positioning frame is fixed or not can be adjusted by adjusting the positioning screw, so that the forearm strength of a practicer can be exercised;

7. the bow body can realize the up-and-down adjustment of the position so as to adapt to exercisers with different heights;

8. the exerciser has simple integral structure, convenient operation and low preparation cost.
