Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a pull-up power-assisting device. Background Art

[0002] Pull-ups are a common form of exercise, a hanging strength exercise that uses one's own strength to overcome one's own weight. In order to help weaker trainees gradually adapt to the exercise process, they often need to rely on power-assisting equipment to help them complete the transition in the initial stage. However, existing power-assisting devices are often relatively fixed and cannot be adjusted in time according to the trainee's height. Moreover, after being installed, they cannot be abandoned during training, and training must be interrupted to remove the power-assisting equipment, which affects the training rhythm and greatly reduces the exercise effect. Utility Model Content

[0003] The utility model aims to provide a pull-up power-assisting device to solve the problem that the existing power-assisting device cannot be timely adjusted according to the height of the trainee and cannot be abandoned during training.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A pull-up assist device comprises a lifting bracket, a cross bar is provided on the lifting bracket, a mounting plate is provided in the middle of the cross bar, a base plate is rotatably mounted on the mounting plate through a rotating shaft, a plurality of assist springs are provided on the base plate, a pedal is provided at the upper end of the plurality of assist springs, a foot fixing sleeve is provided on the pedal, a plurality of first magnetic fixing plates are provided on the mounting plate around the rotating shaft, the plurality of first magnetic fixing plates are mutually differed by an angle of 90°, and a second magnetic fixing plate cooperating with the first magnetic fixing plate is symmetrically provided on the base plate.

[0006] Furthermore, the lifting bracket includes two lifting arms arranged opposite to each other, the lifting arms include a fixed arm and a movable arm, the cross bar is connected to the movable arm, the lower end of the movable arm is inserted into the fixed arm, the fixed arm is provided with a fixing pin, and the movable arm is provided with a plurality of pin holes cooperating with the fixing pin.

[0007] Furthermore, a clamping block is detachably provided at the lower end of the fixed arm, and a fixing slot is provided at the lower end of the clamping block.

[0008] Furthermore, the upper side wall of the movable arm is provided with a guide cylinder adapted to the cross bar, and a locking screw for the cross bar is threadedly connected to the guide cylinder.

[0009] Furthermore, a buffer pad is provided at the upper end of the pedal, and the foot fixing sleeve is provided on the buffer pad.

[0010] The utility model has the following advantages:

[0011] The bracket can be raised and lowered to accommodate trainees of different heights, thereby providing assistance to the trainee with the help of the assist spring. During training, if the trainee does not need assistance, the trainee can use the force of the feet to rotate the bottom plate to be perpendicular to the crossbar, thereby leaving space for the trainee's feet to move, so that the trainee no longer needs to rely on assistance to perform pull-ups and does not need to interrupt training by getting off the bar.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] refer to Figure 1-5 As shown, one embodiment of the utility model is:

[0025] The pull-up assisting device comprises a lifting bracket, a cross bar 1 is provided on the lifting bracket, a mounting plate 2 is provided in the middle of the cross bar 1, a bottom plate 4 is rotatably mounted on the mounting plate 2 via a rotating shaft 3, a plurality of assisting springs 5 ​​are provided on the bottom plate 4, a pedal 6 is provided at the upper end of the plurality of assisting springs 5, a foot fixing sleeve 7 is provided on the pedal 6, a plurality of first magnetic fixing plates 8 are provided on the mounting plate 2 around the rotating shaft 3, the plurality of first magnetic fixing plates 8 are mutually differed by an angle of 90°, and a second magnetic fixing plate 9 cooperating with the first magnetic fixing plate 8 is symmetrically provided on the bottom plate 4.

[0026] The lifting bracket can be adapted to trainees of different heights, so as to provide assistance to the trainees with the help of the assisting spring 5. By setting a first magnetic fixing plate 8 with a 90° angle difference on the mounting plate 2 and cooperating with a second magnetic fixing plate 9 on the bottom plate 4, the bottom plate 4 and the pedal 6 can move within a 90° angle range. In the assisting mode, the bottom plate 4 and the crossbar 1 are parallel to each other. Figure 1 If no assistance is needed during training, the bottom plate 4 can be rotated to be perpendicular to the crossbar 1 by using the foot. Figure 2 As shown, there is room for the trainee's feet to move, so that the trainee no longer needs to rely on power to perform pull-ups and does not need to stop training by lowering the bar.

[0027] It is understandable that due to the shaking of the foot during exercise, the second magnetic fixing plate 9 and the first magnetic fixing plate 8 are prone to repeatedly separate and collide within a small angle, affecting the exercise of the trainer. To avoid or reduce the above interference, the impact on training can be reduced by appropriately increasing the size of the foot fixing sleeve and increasing the stroke of the booster spring.

[0028] In this embodiment, the lifting bracket specifically adopts two lifting arms arranged opposite to each other, the lifting arms include a fixed arm 10 and a movable arm 11, the cross bar 1 is connected to the movable arm 11, the lower end of the movable arm 11 is inserted into the fixed arm 10, the fixed arm 10 is provided with a fixing pin 12, and the movable arm 1 is provided with a plurality of pin holes 13 matched with the fixing pin 12. Through the above connection method, the lifting adjustment is simple and convenient, and the cost is low.

[0029] A clamping block 14 is detachably provided at the lower end of the fixed arm 10 , and a fixing slot is provided at the lower end of the clamping block 14 .

[0030] The provided clamping block 14 can be fixed to the pull-up bracket to ensure the stable position of the power-assisting device.

[0031] The upper side wall of the movable arm 11 is provided with a guide cylinder 15 adapted to the cross bar 1 , and a locking screw 16 for the cross bar 1 is threadedly connected to the guide cylinder 15 .

[0032] A buffer pad 17 is disposed at the upper end of the pedal 6 , and the foot fixing sleeve 7 is disposed on the buffer pad 17 .

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
