Abstract

The utility model belongs to the field of sports equipment, and relates to an exerciser imitating throwing a solid ball. It mainly consists of two sliding sleeves, a bottom plate, two inserting rods, a square tube, an upper plate, a lower plate, two baffle plates, and a handle. , a small square tube, the first hanging ring, the second hanging ring, and an extension spring are connected to each other to form. When using this exerciser, increase or decrease extension springs as required. Adjust the height of the square tube up and down so that the handle is placed on the head, and then screw the screws to fix the two inserting rods. Stand on the floor with your feet forward and backward, and hold the handles with both hands to stretch the tension springs at the openings of the upper and lower plates to practice. The beneficial effect of using the exerciser is that the increase or decrease of the extension spring can meet the practice needs of improving the speed and strength of the shot, and is conducive to improving the performance of throwing medicine balls; Standardize the reasonable forceful release angle of the medicine ball throw.

Description

The medicine ball exercising machine of exerting oneself is thrown in imitation

Technical field

The utility model belongs to the sports field, relates to a kind of imitation and throws the medicine ball exercising machine of exerting oneself.

Background technology

Existing throwing medicine ball exists following problem: a, throwing to be conducive to improve release speed less than the standard weights medicine ball, throwing is conducive to improve the strength of selling greater than the standard weights medicine ball, this is to improve an effective means of throwing the medicine ball achievement, but throw in the medicine ball exercise in reality, then can't improve release speed and strengthening exercise owing to lacking a plurality of medicine balls that are greater than or less than standard weights.B, beginner throw the means device that the medicine ball exercise lacks the standard angle of trajectory.

Summary of the invention

The purpose of this utility model is the problem that exists in the above-mentioned background technology for solving preferably, provide a kind of imitation to throw the medicine ball exercising machine of exerting oneself, the technical scheme that it is taked is by consisting of with lower member: two sliding sleeve lower ends and being welded to connect above the base plate, two inserted link lower ends are inserted respectively sliding sleeve and are connected by screw fastening, be welded to connect with the inserted link upper surface below the square tube, be welded to connect respectively upper plate and lower plate in the square tube front, line parallel to the ground is 45 ° of angles after the following welding of described upper plate, line parallel to the ground is 38 ° of angles after the top welding of described lower plate, two baffle plates place respectively the both sides of upper plate lower plate, handle passes two baffle holes and is welded to connect, handle two outer ends and little square tube the inner are welded to connect, be welded to connect the first link at little square tube rear end face, be welded to connect the second link in the square tube front, extension spring two ends hook is hung on respectively the first link and the second link.

When using this exercising machine, increase and decrease as required extension spring.Adjust up and down the square tube height handle is placed on the head, screw again screw and fix two inserted links.The bipod staggered lunging position stands in above the base plate, and two hold make progress plate and lower plate opening part stretching extension spring of handle realizes exercise.

Use the beneficial effect of this exercising machine: a, increase and decrease extension spring can satisfy the exercise needs that improve release speed and strength, be conducive to improve throwing medicine ball achievement; B, handle brandish between 38 °-42 ° of upper plate and lower plates and are conducive to limit the rationally angle of trajectory firmly that standard is thrown medicine ball.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is done in further detail explanation.

Fig. 1 is that the exert oneself agent structure simplified schematic diagram of exercising machine of medicine ball is thrown in imitation;

Fig. 2 is the A-A diagrammatic cross-sectional view of Fig. 1;

The specific embodiment

With reference to accompanying drawing, two sliding sleeve 12 lower ends and being welded to connect above the base plate 1, two inserted link 10 lower ends are inserted respectively sliding sleeve and are fastenedly connected by screw 11, be welded to connect with the inserted link upper surface below the square tube 2, be welded to connect respectively upper plate 5 and lower plate 4 in the square tube front, line 3 parallel to the ground is 45 ° of angles after the following welding of described upper plate, line parallel to the ground is 38 ° of angles after the top welding of described lower plate, two baffle plates 6 place respectively the both sides of upper plate lower plate, handle 7 passes two baffle holes and is welded to connect, handle two outer ends and little square tube 8 the inners are welded to connect, be welded to connect the first link 14 at little square tube rear end face, be welded to connect the second link 13 in the square tube front, extension spring 9 two ends hook is hung on respectively the first link and the second link, as shown in Figure 2.
