[0026] refer to Figure 1-4As shown, one embodiment of the utility model is:

[0027] A long jump test device comprises a soft cushion 1, one end of the soft cushion 1 is provided with a U-shaped bottom frame 2, the other end of the soft cushion 1 is provided with a take-off pedal 3, a telescopic frame mechanism is provided between the take-off pedal 3 and the U-shaped bottom frame 2, a protective frame 4 is symmetrically provided on the inner side of the U-shaped bottom frame 2, a distance measuring module 5 is installed on one of the protective frames 4, a voice playing module 6 is installed on the other protective frame 4, and a protective plate 7 is provided on the protective frame 4 and the U-shaped bottom frame 2.

[0028] When in use, the soft cushion 1 is unfolded through the telescopic frame mechanism, and the U-shaped bottom frame 2, the take-off pedal 3, and the telescopic frame mechanism arranged around the soft cushion 1 are used to ensure the flatness of the soft cushion 1 and the accuracy of the test results. The long jump results are measured by the distance measuring module 5 and played in real time through the voice playing module 6, so that the recorders and trainees can know the long jump results in time, which is more efficient. In a specific embodiment, scale lines are provided on both sides of the soft cushion to facilitate the calibration of the long jump data.

[0029] The telescopic frame mechanism is used to facilitate the storage of the test device, reduce the size of the test device, and facilitate the staff's transportation. The U-shaped bottom frame adopts a hollow tube structure to facilitate cable layout.

[0030] Since students are prone to fall due to unstable standing during long jump, in order to avoid damage to electrical appliances near the landing point, a protective frame 4 and a protective plate 7 are used for protection. Figure 2 As shown, in a specific implementation, the two ends of the protection frame 4 are respectively connected to the side plates and the bottom plate of the U-shaped bottom frame to form a stable triangular structure.

[0031] like Figure 1 As shown in Figure 2, in this embodiment, the telescopic frame mechanism includes a first square tube 8 and a second square tube 9. A first cylinder 10 is provided in the first square tube 8, and the movable end of the first cylinder 10 is connected to the second square tube 9. A second cylinder 11 is provided in the second square tube 9, and the movable end of the second cylinder 11 is connected to the U-shaped bottom frame 2.

[0032] Specifically, a limiting plate 12 is provided on a side of the second square tube 9 facing the first square tube 8 , and the limiting plate 12 is threadedly connected to the second square tube 9 .

[0033] The telescopic frame mechanism uses a cylinder set in a square tube for driving, which has a simple structure and is easy to implement. A two-stage telescopic structure is adopted to avoid the problem of excessive cylinder size caused by using a one-stage telescopic structure. The first square tube 9 and the second square tube 8 both have a certain weight, which solves the problem of weight imbalance of the side frame and ensures that the soft cushion is unfolded flat. In the specific implementation, the length dimension of the first square tube 8 is greater than the length dimension of the second square tube. Correspondingly, the length dimension of the first cylinder 10 therein is greater than the length dimension of the second cylinder.

[0034] like Figure 1 As shown in Figures 2 and 3, in the present embodiment, the take-off pedal 3 is bonded and fixed to the cushion 1, and a folding plate 13 adapted to the first square tube 2 is provided at the end of the take-off pedal 3, the vertical portion of the folding plate 13 abuts against the side wall of the first square tube 8, and the lower end of the vertical portion is connected to the end of the take-off pedal 3, the horizontal portion of the folding plate 13 abuts against the upper wall of the first square tube 8, and the horizontal portion is threadedly connected to the first square tube 8.

[0035] The folding plate arranged at the end of the take-off pedal can provide limited support for the first square tubes 8 on both sides to ensure the flatness of the soft point. The threaded connection method facilitates its disassembly and maintenance. In specific implementation, the folding plate 13 is integrally formed with the take-off pedal 3 to ensure structural strength.

[0036] like Figure 1 As shown in Figures 2 and 4, in this embodiment, a mounting port 14 adapted to the second cylinder 11 is provided on the second square tube 9, and a mounting plate 15 is provided on the mounting port 14. The second cylinder 11 is located in the mounting port 14 and is fixedly connected to the mounting plate 15, and the mounting plate 15 is threadedly connected to the second square tube 9.

[0037] The second cylinder 11 is placed in the mounting opening 14 and fixedly connected to the mounting plate 15 . After the mounting plate 15 is removed, the second cylinder 11 can be easily taken out.

[0038] 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.
