Description

TECHNICAL FIELD

[0001] The present application relates to the field of sports equipment, in particular to a physical training device with pull-up evaluation function. BACKGROUND

[0002] The pull-up single bar with evaluation function is a sports examination device integrating intelligent sensing technology, automatic counting and action specification detection, mainly used in military training, school physical examination, gymnasium and other scenes. It monitors the action standardization in real time through sensors and algorithms, automatically records the score and generates a report.

[0003] A power-assisted single bar is disclosed in Chinese patent CN203777569U, which comprises a base, a stand and a grip bar. Two stands are arranged left and right, and the lower ends of the two stands are fixed on the base and supported by the base. The grip bar is installed between the two stands. The power-assisted support bar includes a front crossbar, a rear crossbar, a vertical support bar, a connecting rod connected between the front crossbar and the rear crossbar, and a connecting inclined rod connected between the front crossbar and the vertical support bar. The front crossbar and the rear crossbar are horizontally arranged and parallel to the grip bar. The distance between the front crossbar and the rear crossbar is 10 cm. The lower end of the vertical support bar is installed on the upper end of the stand. The pulley block is provided with three groups of first, second and third pulley blocks. The connecting line on the right side passes through the three fixed pulleys on the right side of the first, second and third pulley blocks in sequence, and its end is connected with the weight in the cavity outside the right stand.

[0004] For the above-mentioned related technology, the existing single bar provides power assistance function for users, but when using it, the user needs to manually pull the rope to lift the weight used for counterweight first, and then connect one end of the cable to the harness on the user's body. In this way, the user can transmit force through the rope during pull-up, offset part of the user's own gravity, and thus achieve the effect of power assistance. However, the user needs to manually pull the weight before each pull-up, and the weight needs to be lifted. When the weight is heavy, more physical strength is needed to pull the weight each time, and it is more troublesome to use the single bar with power assistance function.

[0005] And the existing single bar generally only has power assistance function and cannot exert resistance to the user when the user uses it. Some users with excellent physical fitness will connect barbell plates on the widened waistband to increase the weight and improve their strength training level when using the single bar. However, there is a risk of barbell plate falling and causing injury when the barbell plate is hung on the waist. The existing single bar cannot easily provide resistance function for the user during training.

[0006] The existing pull-up training equipment generally adopts the mode of setting adjusting hole positions at the upper end of the stand column in the height direction, adjusting the height of the crossbar by inserting the crossbar into the adjusting hole positions at different height positions, and then adapting to users of different heights. However, this adjusting mode needs the staff to first pull out the crossbar or release the locking of the crossbar according to the height of the user, adjust the crossbar to the appropriate position, and then restore the locking. The adjustment process is relatively troublesome, and in order to avoid the user's foot from touching the ground during use, the height of the crossbar needs to be reached by the user jumping up. For some users with weak strength, it is difficult to jump up to grasp the crossbar and maintain the standard grip position.

[0007] In summary, the existing physical training equipment with pull-up evaluation function is not easy to conveniently provide power or resistance use mode for users of different heights. SUMMARY

[0055] Third embodiment: A physical training device with pull-up evaluation function, please refer to Figures 1-12On the basis of the second embodiment, different from the second embodiment is that the counterweight 7 is rotationally connected with a rotating column 25, the rotating column 25 is fixedly connected with a plug 26, the counterweight 7 is fixedly connected with parallel connecting strips 27 above the rotating column 25, and the connecting strips 27 are provided with sockets 28 for plug-in cooperation of the plug 26.

[0056] Specifically, the plug 26 includes an annular part with a same axis as the rotating column 25, when the rotating column 25 rotates, the arc part of the plug 26 rotates around the axis of the rotating column 25 and is inserted into the corresponding socket 28, the plug 26 can be inserted into the socket 28 of the counterweight 7 below, and the adjacent two counterweights 7 are connected and combined by the plug 26 passing through the perforations on the connecting strips 27, and the combination between the two adjacent counterweights 7 can be released by reversely rotating the rotating column 25 to make the plug 26 exit from the socket 28.

When the mobile box 9 is rising, the electromagnetic plug 20 is inserted into the nearest jack 901 by the elastic force of the tail end compression spring, and as the height of the crossbar 6 continues to rise, the user's feet can be out of contact with the protective pad 5, and then the positioning assembly 22 is calibrated to the same height, so that the crossbar 6 remains horizontal, and the user can start the pull-up. The camera assembly at both ends of the crossbar 6 shoots the whole process of pull-up evaluation, and after the user completes the pull-up, the crossbar 6 is released and jumps down, and the telescopic column 8 is retracted and reset. After the set time, the electromagnetic plug 20 is also temporarily restored to power to make the sliding box 19 slide and reset under its own gravity, so that the next user can perform pull-up; When the user needs assistance to perform pull-up, first wear the belt or five-point safety belt around the waist, stand under the crossbar 6, and rotate the rotating rod 12 in the stand 1 to disengage from the second buckle 15, and then extend the telescopic column 8. At this time, the telescopic column 8 is pressed by the mobile box 9 at the top, and the bottom is not limited, so the fixed section of the telescopic column 8 will move downward relative to the telescopic section, so that the mounting plate 10 approaches and contacts the buffer pad 13, and then the rotating rod 12 is rotated and buckled with the first buckle 14. During the retraction of the telescopic column 8, the mobile box 9 fixedly connected at the top cannot slide downward due to the limitation of the limiting plate 18, so as the telescopic column 8 is retracted, the counterweight 7 connected together will be lifted up. At this time, the user or the staff can easily connect the end of the assisting rope to the belt or five-point safety belt on the user's body. After the assisting rope is connected, the rotating rod 12 is rotated and disengaged from the first buckle 14. At this time, the gravity of the counterweight is transmitted to the user through the assisting rope, which can offset part of the user's body weight, thereby providing assistance when the user performs pull-up. Then the telescopic column 8 is reset to the state where the rotating rod 12 can be buckled with the second buckle 15, and the pull-up can be performed as usual without assistance or resistance. When the user needs resistance to perform pull-up, first wear the belt or five-point safety belt around the waist, stand under the crossbar 6, and directly pick up the resistance rope from the ground and connect it to the belt or five-point safety belt. The resistance rope transmits force through the pulley, so that the user needs to resist the gravity of the counterweight when performing pull-up, thereby providing resistance to the user during pull-up evaluation.
