The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Example 1

[0030] A convenient vertical jump tester, such as Figure 1-5 As shown, it includes a base plate 1 and a control console 7. In order to make the measurement sufficiently accurate, a support rod 2 is installed on the base plate, and a measuring rod 3 is installed above each of the two support rods 2. A top plate 4 is arranged on the top ends of the two measuring rods 3. A measuring plate 5 is slidably installed on the two measuring rods 3. A light transmitter 16 is installed on the lower surface of the measuring plate 5. A light receiver 17 is installed on the base plate 1. Both the light transmitter 16 and the light receiver 17 are connected to the control console 7 by signal.

[0031] With the solution, the tester only needs to jump vertically with force and push the test board as high as possible with his hands. The light transmitter and the light receiver measure the height to ensure the accuracy of the data.

[0032] The device is further configured as follows: a support plate 13 is installed in the measuring plate 5, a telescopic rod 12 is fixed on the support plate 13, the output end of the telescopic rod 12 is connected to a push plate 10, a clamping block 14 is installed on the push plate 10, a spring 11 is covered on the outer surface of the telescopic rod 12, and the two ends of the spring 11 are respectively connected to the support plate 13 and the push plate 10, a telescopic cylinder 9 is also installed in the measuring plate 5, and the output end of the telescopic cylinder 9 is facing the push plate 10, a plurality of fins 15 are evenly provided on the inner side of the measuring rod 3, and a plurality of the fins 15 are inclined upwards, and the telescopic cylinder 9 is connected to the control console 7 by signal.

[0033] Through the scheme, when the tester pushes the measuring plate upward, the spring pushes the push plate to clamp the block into the fin. Since the fin is tilted upward, the measuring plate can be pushed upward and cannot fall. When the tester jumps up and falls, the measuring plate will stop in place, making the test result more accurate. It only needs to control the telescopic cylinder to push the push plate to bring out the block, and the measuring plate can fall, which is convenient for the next tester to use.

[0034] The device is further configured such that a limiting block 6 is installed at the bottom end of the measuring rod 3 .

[0035] By setting the limit block, when the measuring plate falls, it will be blocked by the limit block to prevent it from falling to the ground and causing damage to the light transmitter.

[0036] The device is further configured such that a plurality of universal wheels 8 are installed below the console 7, the support rod 2 and the base plate 1 are connected via bolts and screw holes, and the support rod 2 and the measuring rod 3 are connected via bolts and screw holes.

[0037] Through the solution, the device can be easily disassembled for storage and movement, and the use site can be changed.

[0038] The device is further configured such that an anti-slip pad 19 is provided on the bottom plate 1 .

[0039] By setting up anti-slip mats, the testers can effectively avoid slipping and falling when jumping or landing.

[0040] The device is further configured such that a protective pad 20 is installed on the lower surface of the measuring plate 5 .

[0041] By setting up the protection pad, the hands of the tester are effectively protected during the test to avoid hurting the fingers when pushing the test board.

[0042] The device is further configured such that a groove is provided on the upper surface of the bottom plate 1, the light receiver 17 is installed in the groove, and a protection plate 18 is installed on the groove, and the protection plate 18 is made of a transparent material.

[0043] The solution prevents the tester from jumping and falling and injuring the light receiver at the bottom, thereby extending the service life of the device.

[0044] Working principle: the tester only needs to stand on the bottom plate 1 and jump high, and stretch out the measuring plate 5, the spring 11 pushes the push plate 10 to clamp the block 14 into the fin 15, and since the fin 15 is tilted upward, the measuring plate 5 can be pushed upward and cannot fall. When the tester jumps up and falls, the measuring plate 5 will stop in place. At this time, the light transmitter 16 and the light receiver 17 will measure the distance and send the data to the console 7. After recording, start the telescopic cylinder 9 to push the push plate 10 to bring out the block 14, and the measuring plate 5 can fall and be blocked by the limit block 6 to complete the reset.
