Description

A kind of multi-person pull-up auxiliary training equipment and horizontal bar structure

technical field

The invention belongs to the field of sports equipment and equipment, and relates to a sports equipment for practicing pull-up movements, in particular to a sports equipment that can achieve power assistance and can simultaneously train multiple people.

Background technique

Pull-up is a compound movement exercise that requires the participation of upper limbs and many back muscles. It is a comprehensive reflection of upper limb strength, physical coordination, endurance, explosive power and other physical fitness levels. It is not only one of the national physique monitoring indicators, but also the physical health of students in primary and secondary schools. Test metrics. According to the "2014 National Physical Fitness Monitoring Bulletin", in the test data of 13-19-year-old youth pull-ups, the average number of pull-ups completed by the 16, 17, and 18-year-old age groups in the high school segment was 3.8, 4.2, and 4.5, respectively. According to the "National Physical Health Standards for Students (Revised in 2014)", the passing standards are 7, 8, and 9 respectively, while in the "National Physical Exercise Standards" promulgated in 1989, high school boys need to achieve more than 10 to pass. It shows that the upper body strength of high school students is extremely weak and needs to be strengthened urgently.

At present, the pull-up exercise has been popularized in junior high school and high school. In the middle school sports test, the pull-up is a test item for boys. The standard action of the pull-up is to rely on the arm strength and waist and abdominal muscles to pull the person up until the chin is higher than the horizontal bar of the horizontal bar, and then lower until the arm is straight to complete a pull-up action. However, in the process of teaching and exams, students often cannot complete the standard pull-up movements, but rely on the way of swinging their legs or shaking their bodies to give an inertia, and then the arms can exert force. Such wrong movements are not conducive to The development of students' physical fitness cannot achieve the expected results of the test. Under the requirements of standard movement specifications, relying entirely on arm strength and abdominal muscles, most students complete very little or even one of them. Over time, they will lose confidence in this project, which is not conducive to students' strength training.

After research, it was found that if you want to reverse the posture of students doing pull-ups, a scientific training mechanism must be established, and a pull-up auxiliary exercise equipment must be invented, so that students with weak physical ability can gradually improve their pull-ups under the premise of standardizing movements. Up grades. In addition, the pull-up is currently tested on the horizontal bar. Due to the limited number of horizontal bars in campus or community fitness venues, it cannot meet the exercise needs of a large number of students. Therefore, it is necessary to design a pull-up training equipment for multiple people to meet the needs of Multiple people training at the same time.

SUMMARY OF THE INVENTION

In order to solve the above problem, the present invention provides a horizontal bar structure that can increase the upward assist. When using the arms and abdominal muscles to exert force, the equipment can assist the trainer with an upward force, offset part of the self-gravity, and help the trainer. For the trainer to practice the basic force-generating movements, gradually increase the muscle strength of the trainer, realize the correct force method, and finally complete the standard pull-up movements.

The technical scheme adopted in the present invention is a pull-up auxiliary training equipment for multiple people, the training equipment includes a set of horizontal bar structures composed of a horizontal bar and a vertical column, the horizontal bar structures are fixedly connected by means of connecting rods, and the horizontal bar structures are The structures are arranged in parallel, and the key point is that the horizontal bar structure is also provided with a booster plate, and the two sides of the booster plate respectively have the freedom of vertical upward movement by means of symmetrically arranged drive mechanisms.

The driving mechanism includes a counterweight block, which is fixedly connected to the booster plate by means of a wire rope mechanism.

The wire rope mechanism includes a pulley seat fixed on the upright column, a set of fixed pulleys fixed on the pulley seat, and a steel wire rope fixed between the counterweight block and the booster plate.

The pulley seat is inserted and fixed in the column, and a through hole is also opened on the column above the pulley seat, and the steel wire rope passes through the through hole.

The invention also relates to a horizontal bar structure for auxiliary training of pull-ups, which is consistent with the idea of the auxiliary training equipment for pull-ups used by many people. The horizontal bar structure includes a horizontal bar and a column. , the two sides of the booster plate respectively have vertical upward movement degrees of freedom by means of symmetrically arranged drive mechanisms.

The driving mechanism includes a counterweight block, which is fixedly connected to the booster plate by means of a wire rope mechanism.

The wire rope mechanism includes a pulley seat fixed on the upright column, a set of fixed pulleys fixed on the pulley seat, and a steel wire rope fixed between the counterweight block and the booster plate.

The pulley seat is inserted and fixed in the column, and a through hole is also opened on the column above the pulley seat, and the steel wire rope passes through the through hole.

The beneficial effect of the present invention is that, by adding a booster structure, when the trainer exerts upward force, after the counterweight changes its direction through the fixed pulley through its own gravity, the booster plate can give the trainer an upward thrust, which is equal to the counterweight. The reaction force of gravity during free fall can help lifters perform pull-ups more easily. Moreover, the weight of the counterweight can be adjusted at any time according to the different ability stages of the trainer, reducing the weight of the counterweight in turn, and finally realizing the standard pull-up action without the auxiliary training equipment.

At the same time, equipment used by multiple people can be used for multi-person training at the same time, allowing more people to train at the same time. What is more beneficial is that multiple people can play a variety of competition modes, including unified observation of movement standards. , the movements are more standard than anyone else, which is incomparable in traditional one-person training. Multiple rounds of challenge and promotion mode can also be used. For example, the first horizontal bar has a heavier weight, and the next one is lighter, so that the trainer can quickly find a training position suitable for his current strength. Avoid the trouble of frequent replacement of weights.

Detailed ways

As shown in Figure 1, a multi-person pull-up auxiliary training equipment, the training equipment includes a set of horizontal bar structures composed of a horizontal bar 1 and a vertical column 2, and the horizontal bar structures are fixedly connected by means of connecting rods 3, and The horizontal bar structures are arranged in parallel, and the key is: the horizontal bar structure is also provided with a booster plate 7, and the two sides of the booster plate 7 respectively have the freedom of vertical upward movement by means of symmetrically arranged drive mechanisms. By adding a structure in which the driving mechanism cooperates with the booster plate 7, when the trainer exerts upward force, the drive mechanism can make the booster plate give the trainer an upward thrust, which can help the trainer to complete the pull-up action more easily.

The driving mechanism includes a counterweight 6, and the counterweight 6 is fixedly connected to the booster plate 7 by means of a wire rope mechanism. The weight block 6 can be changed at any time, and the required power of assistance can be adjusted according to the current ability level of the trainer. The counterweight 6 and the wire rope mechanism can be connected by a buckle, which is convenient for disassembly and replacement.

The wire rope mechanism includes a pulley base 4 fixed on the column 2 , a set of fixed pulleys 5 fixed on the pulley base 4 , and a wire rope 8 fixed between the counterweight 6 and the booster plate 7 . The four corners of the booster plate 7 are respectively connected with steel wire ropes, and each side is connected to the main steel wire rope by two steel wire ropes, so that the force given by the counterweights 6 on both sides is relatively uniform, so as to prevent the booster plate 7 from tilting to one side, which may cause fear to the trainer. illusion.

The pulley seat 4 is inserted and fixed in the column 2 , and a through hole 9 is also opened on the column 2 above the pulley seat 4 , and the wire rope 8 passes through the through hole 9 . The purpose of this solution is to ensure that the center of gravity of the booster plate 7 is directly below the horizontal bar 1, and at the same time to avoid the situation that the center of gravity of the horizontal bar is unstable due to the counterweight 6 and the wire rope mechanism being on one side of the horizontal bar.

As shown in Figure 2-4, a horizontal bar structure for assisting pull-up training includes a horizontal bar 1 and a column 2. The key point is that the horizontal bar structure is also provided with a booster plate 7, and the two sides of the booster plate 7 are arranged symmetrically. The drive mechanism has a vertical upward movement degree of freedom. The above structure is the same design idea as the multi-person pull-up auxiliary training equipment. The horizontal bar structure is actually a part of the multi-person pull-up auxiliary training equipment. It has been introduced in detail above, and I will not repeat it here.

The horizontal bar structure of the present invention is the core technology. On the basis of the horizontal bar structure, an auxiliary structure for lifting power is added, which can make the trainer more easily practice the standard pull-up action. At the same time, the pull-up auxiliary training equipment used by multiple people can be performed by multiple people at the same time, and multiple competition modes can be performed between multiple people. The present invention is easy to improve on the basis of the existing technology, and the added solution is low in cost, and is suitable for primary schools and junior high schools.
