[0002] As a sports instrument that combines physical fitness testing and physical training, the vertical jumper is widely used in school sports activities, athlete training fields and other occasions. It is especially suitable for measuring students' jumping ability and athletes' vertical jump height in professional training.

[0003] In existing height probes, multiple scales are sequentially mounted on a rotating shaft. Adjacent scales are spaced by shims that move on the rotating shaft to increase the distance between them and keep them parallel. This prevents adjacent scales from tilting during use, which could cause interference and affect the accuracy of the height test.

[0004] In actual use, because the pad is movably mounted on the rotating shaft, when the tester jumps up and hits the ruler, the hit ruler rotates around its rotating shaft and also drives the adjacent ruler to rotate through the pad, thus causing the measurement result of the height test to deviate from the actual result.

[0029] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0030] Example 1:

[0031] like Figure 1-3 As shown, the height measuring device provided by this utility model includes a ruler frame 1, a rotating shaft assembly 2 and a ruler 3. The ruler frame 1 is F-shaped and the rotating shaft assembly 2 is fixedly installed vertically at the center of its open end with a bolt. Several independent rulers 3 are equidistantly distributed and rotated along its length direction on the rotating shaft assembly 2.

[0032] The rotating shaft assembly 2 includes a rotating shaft 21 and partition plates 22. Multiple partition grooves 23 are symmetrically and equidistantly spaced along the length of the outer periphery of the rotating shaft 21. Each partition groove 23 contains a partition plate 22, preferably in the shape of a U-shape. A scale 3 is rotatably mounted on the rotating shaft 21 between adjacent partition plates 22. The partition plates isolate each scale, allowing it to rotate independently on the rotating shaft without contacting each other. Furthermore, the partition plates can be quickly removed from the rotating shaft for easy maintenance and replacement.

[0033] The thickness of the separator 22 is 0.5-8mm, which makes the testing accuracy more accurate and the height calculation more convenient.

[0034] Example 2:

[0035] The rotating shaft assembly 2 includes a rotating shaft 21 and a partition ring 24; a plurality of partition rings 24 are equidistantly arranged on the outer periphery of the rotating shaft 21 along its length direction; a scale 3 is rotatably arranged on the rotating shaft 21 between adjacent partition rings 24; the partition rings isolate each scale so that it is independently rotatable on the rotating shaft and does not contact each other.

[0036] The thickness of the separator ring 24 is 0.5-8mm, which makes the test accuracy more accurate and the height calculation more convenient.

[0037] The rotating end of the scale 3 is provided with an arc-shaped rotating part 32 that rotates with the rotating shaft 21. The arc-shaped rotating part 32 consists of a fixed ring 321 and a movable ring 322 fixed on the rotating end of the scale 3. The two ends of the fixed ring 321 and the movable ring 322 are fixedly connected by bolts, which facilitates disassembly and installation.

[0038] Example 3:

[0039] The rotating shaft assembly 2 includes a rotating shaft 21 and an annular groove 25; multiple annular grooves 25 are equidistantly provided on the outer periphery of the rotating shaft 21 along its length direction, and an annular protrusion 323 is provided on the inner side of the arc-shaped rotating part 32 to rotate and cooperate with the annular groove 25; through the rotational cooperation of the annular groove and the annular protrusion, each scale is independently rotated on the rotating shaft and does not contact each other.

[0040] Example 4:

[0041] The height measuring device provided by this utility model also includes a ruler assembly 4 consisting of a support base 41, a shaft hole 42, and a stop bar 43. The support base 41 is horizontally fixedly connected to both ends of the opening of the ruler frame 1. The support base 41 has shaft holes 42 at both ends. The stop bar 43 is bolted into the shaft hole 42 on the same side of the support base 41. The stop bar is the reference line for ruler alignment, and the stop bar can be installed on either side of the ruler frame according to the actual situation.

[0042] The height reach device provided by this utility model also includes a U-shaped reset ruler 5. The two ends of the open end of the reset ruler 5 are rotatably connected to the upper and lower ends of the rotating shaft 21, respectively. The open end and the closed end of the reset ruler 5 are respectively provided with a traction hole 51 and a reset hole 52. A traction rope is connected to both the traction hole 51 and the reset hole 52. This makes it convenient for users to use the reset ruler to adjust the scale. The reset ruler can be placed on the same plane as the scale frame. When the tester jumps up and hits the scale, causing it to rotate, it will eventually collide with the reset ruler. However, at this time, the reset ruler will move along the direction of the force applied to the scale and gradually decelerate, without rebounding in the direction of the scale. This improves the accuracy of the height reach test data and solves the problem of its safety hazards.

[0043] The rotating shaft 21 has bushings 211 at both ends, located between the reset ruler 5 and the adjacent scale 4, so that the scale and the reset ruler are kept in balance and friction between the scale and the reset ruler is avoided during use, which would affect the accuracy of the test.

[0044] The ruler frame 1 is also connected to a telescopic base 6 at its bottom end, enabling height adjustment.

[0045] In this invention, the ruler is mounted on the ruler frame via a rotating shaft assembly. When the tester jumps up and strikes the ruler, the struck ruler rotates around the rotating shaft without causing adjacent rulers to rotate. This also keeps adjacent rulers parallel to each other, avoiding the problem of interference caused by tilting between adjacent rulers during use. This improves the accuracy of the vertical jump test results and optimizes the user experience.

[0046] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
