Technical Field

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

[0002] Pull-ups are a common form of exercise. It is a hanging strength exercise that uses one's own strength to overcome one's own weight. Hold both hands on a suspended horizontal bar, use both arms to pull the body hard so that the head passes over the bar, then descends and repeats the above steps.

However, the existing test devices are often in relatively fixed positions, making it difficult to monitor whether the pull-ups of people of different body shapes are standard, resulting in errors in the results statistics.

[0024] refer to Figure 1-3 As shown, one embodiment of the utility model is:

[0025] The pull-up testing device includes vertical arms 1 arranged relatively to each other, a horizontal arm 2 is provided at the upper end of the vertical arm 1, a horizontal bar 3 is provided between the two horizontal arms 2, a first sensing device 4 is provided on the horizontal arm 2 below the horizontal bar 3, a mounting plate 5 is vertically provided on the horizontal arm 2, a second sensing device 6 is provided on the mounting plate 5, a driving member for driving the second sensing device 6 to move up and down is provided on the mounting plate 5, a counting module 7 is provided on the vertical arm 1, and the counting module 7 is connected to the first sensing device 4 and the second sensing device 6.

[0026] Specifically, the first sensing device 4 and the second sensing device 6 both include an infrared transmitter and an infrared receiver that cooperate with each other. The infrared transmitter and the infrared receiver are symmetrically installed to achieve signal connection.

[0027] By arranging the first sensing device 4 below the horizontal arm 2 and the second sensing device 6 above the horizontal arm 2, and the height of the second sensing device 6 can be adjusted by the driving member, the height of the second sensing device 6 is adjusted by the driving member according to the body shape of the testee before the test, to ensure that when the testee is pulled upward, the lower jaw passes over the horizontal bar 3 to block the signal recognition of the infrared transmitter and infrared receiver of the second sensing device, thereby ensuring the standard of the testee's movements.

[0028] Before the pull-up movement, the first sensing device and the second sensing device both recognize the infrared signal. Then the tester pulls upward, the first sensing device loses the signal, and continues to pull upward until the second sensing device loses the signal once, that is, the tester's chin has passed the horizontal bar 3. Then the tester descends and the second sensing device recognizes the infrared signal. Continue to descend until the first sensing device recognizes the infrared signal again, that is, a standard pull-up action is completed, and then the counting module 7 broadcasts it through the voice announcer; if the tester does not block the infrared signal of the second sensing device during the upward traction process, and the first sensing device recognizes the infrared signal again, it means that the pull-up action is not standard, and the counting module 7 does not broadcast or broadcasts the voice information that this action is an invalid action.

[0029] Specifically, the counting module 7 also has a display screen for displaying the score data, so that the tester can understand his or her test data in real time during the test.

[0030] In this embodiment, a mounting groove 8 is opened on the mounting plate 5, and the driving component includes a lead screw 9, a driving motor 10, and a lead screw slider. The lead screw 9 is rotatably installed in the mounting groove 8, and the lower end of the lead screw 9 extends out of the mounting plate 5 and is connected to the driving motor 10. The lead screw slider is connected to the second sensing device 6 through a second mounting block 12.

[0031] Correspondingly, the second sensing device 4 is fixed on the cross arm 2 through the first mounting block 11 ; the counting module 7 and the first sensing device 4 are respectively located on both sides of the cross bar 3 , and the second sensing device 4 is located directly above the first sensing device 6 .

[0032] Furthermore, guide rails 13 adapted to the second mounting block 12 are provided on both sides of the mounting groove 8 on the mounting plate 4 .

[0033] The second sensing device is driven to move on the mounting plate by the lead screw 9, and the positioning accuracy is high. Figure 1 , 2, the lower end of the mounting plate 5 is located below the cross arm 2. The second mounting block 12 is guided and limited by the guide rail 13, thereby reducing the influence of the driving motor 10 on the position of the second sensing device 6 when the driving motor 10 is running.

[0034] In this embodiment, a mounting arm 14 is provided between the two vertical arms, and the counting module 7 is provided on the mounting arm 14. Specifically, the mounting arm 14 is provided close to the horizontal arm 2, so that the tester can observe the test information displayed by the counting module.

[0035] 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.
