Description

Technical Field

[0001] The present application relates to the field of motion measurement, and in particular to a standing long jump tester. Background Art

[0002] Standing long jump refers to long jump starting from a standing position without a running start. It is a sport that combines physical fitness in terms of jumping, explosive power, body coordination and technique. It is a compulsory item in the annual physical fitness test for junior high schools, high schools and universities, and has become one of the important factors in measuring students' physical fitness.

[0003] Currently, there are two methods for measuring standing long jump results. The first and most primitive method uses a ruler. The teacher measures how far you jump while standing still, and then calculates your score. This method has been improved upon. Instead of using a ruler, a rectangular mat with a take-off line and distance markings is laid on the test site. Students jump from outside the take-off line and jump to the corresponding markings. The teacher then uses the corresponding values ​​on the markings to calculate their scores. Both methods are subject to measurement errors, misjudgments, invalid results, and low efficiency. Utility Model Content

The infrared receiving rod is parallel to the infrared transmitting rod. The control panel is arranged on the infrared receiving rod. The display panel is arranged on the infrared receiving rod. The control panel is electrically connected to the infrared transmitting rod, the infrared receiving rod and the control panel.

[0007] By adopting the above technical solution, a test or sports field is arranged on a baseboard, an area at one end between the infrared transmitting rod and the infrared receiving rod is set as a take-off area, and the remaining area between the infrared transmitting rod and the infrared receiving rod is set as a test area. The boundary line between the take-off area and the test area is the foul line. The tester stands in the test area and takes off. If the tester steps on the foul line, the tester blocks the infrared light emitted from the infrared transmitting rod in the foul line area to the infrared receiving rod. The infrared receiving rod in the foul line area cannot receive the infrared light, and the infrared receiving rod transmits an electrical signal to the control panel, which transmits an electrical signal to the display panel, and the display panel displays a foul. After the tester jumps normally to the test area, the infrared light emitted from the infrared transmitter in the test area to the infrared receiver is blocked. The infrared receiver cannot receive the electrical signal and transmits an electrical signal to the control panel, which in turn transmits an electrical signal to the display panel, so that the display panel displays the closest distance between the infrared receiver and the foul line, which is the tester's long jump distance. Manual measurement, calculation, and judgment are no longer required, effectively improving the accuracy and efficiency of measuring standing long jump results.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a standing long jump tester.

[0032] Reference Figure 1 、 Figure 2 The standing long jump tester includes a base plate 1, an infrared transmitting rod 2, an infrared receiving rod 3, a control panel, a display panel, a battery 4, a protective cover 5, a signal light 6 and a light blocking bar 8.

[0033] Reference Figure 1 、 Figure 3 , the infrared transmitting rod 2 is installed on the base plate 1. The infrared transmitting rod 2 is used to transmit infrared rays. The infrared transmitting rod 2 includes a shell 21, an infrared emitter 22 and a connecting piece 23. Multiple shells 21 are installed on the base plate 1. The multiple shells 21 are connected end to end and arranged in the same direction. In this embodiment, an L-shaped angle code is installed on the base plate 1 by bolts. The L-shaped angle code is connected to the shell 21 by bolts to realize the detachable connection between the shell 21 and the base plate 1; the infrared emitter 22 is installed on the inner wall of the shell 21. The infrared emitters 22 in adjacent shells 21 are detachably electrically connected through the connecting terminal. In this embodiment, A strip hole is provided at one end of the shell 21 facing the infrared receiving rod 3 to facilitate the infrared transmitter 22 to send infrared rays; the connecting piece 23 is installed on the shell 21, and the connecting piece 23 is used to connect adjacent shells 21. The connecting piece 23 includes a connecting plate 231 and a lock 232. A slide groove 2311 is provided on the connecting plate 231 along the length direction of the connecting plate 231. An insert 7 is installed on the end of the shell 21 close to the adjacent shell 21. The insert 7 is slidably installed in the slide groove 2311. The lock 232 is installed on one side of the shell 21 close to the adjacent shell 21. The lock 232 is used to buckle to the connecting plate 231.

[0034] During the measurement and transportation process, the shell 21 protects the infrared emitter 22, reducing the possibility of damage to the infrared emitter 22 and extending the service life of the infrared emitter 22. When assembling the infrared transmitting rod 2, the staff will splice the adjacent shells 21 so that the infrared emitters 22 in the adjacent shells 21 are electrically connected, and the embedded block 7 on the shell 21 is embedded in the slide groove 2311, and then the lock 232 is buckled onto the connecting plate 231 to complete the assembly of the adjacent shells 21 and the infrared emitter 22. This allows different numbers of shells 21 and infrared emitters 22 to be assembled, thereby forming infrared transmitting rods 2 of different lengths. The length of the infrared transmitting rod 2 can be adjusted so that the infrared transmitting rod 2 can be suitable for different sports such as standing long jump, single-leg hopping, and shot put. In addition, the adjacent shells 21 and infrared emitters 22 can be disassembled so that the infrared transmitting rod 2 can be disassembled into separate shells 21 and infrared emitters 22, which facilitates the transportation of the infrared transmitting rod 2 and the inspection of the infrared emitter 22 inside the infrared transmitting rod 2.

[0035] Reference Figure 2 、 Figure 3 The light shielding strip 8 is mounted on the side of the housing 21 facing the infrared receiving rod 3, and protrudes above the infrared emitter 22. When external light reaches the housing 21, the light shielding strip 8 blocks the light, reducing the light from being transmitted to the infrared emitter 22. This in turn reduces the light's impact on the infrared rays emitted by the infrared emitter 22, improving the accuracy of subsequent measurements.

[0036] Reference Figure 1 The infrared receiving rod 3 is installed on the base plate 1. The infrared receiving rod 3 is used to receive infrared rays. The infrared receiving rod 3 is parallel to the infrared transmitting rod 2. The area between the infrared receiving rod 3 and the infrared transmitting rod 2 forms a measurement site. In this embodiment, an infrared receiver is installed inside the infrared receiving rod 3. Except that the infrared receiver replaces the infrared transmitter 22 of the infrared transmitting rod 2, the rest of the structure of the infrared receiving rod 3 is the same as that of the infrared transmitting rod 2, so that the infrared receiving rod 3 can also be adjusted in length according to different measurement items and can be disassembled and transported.

[0037] Reference Figure 1 、 Figure 2 A protective cover 5 is installed at the end of the infrared emitting rod 2 and the infrared receiving rod 3 respectively, and the battery 4 is installed in the protective cover 5. The battery 4 in the protective cover 5 on the infrared emitting rod 2 is electrically connected to the infrared transmitter 22 in the infrared emitting rod 2, and the battery 4 in the protective cover 5 on the infrared receiving rod 3 is electrically connected to the infrared receiver in the infrared receiving rod 3.

[0038] The battery 4 can directly power the infrared transmitter 22 in the infrared radiation rod and the infrared receiver in the infrared receiving rod 3. There is no need to pull wires for power supply during measurement, which improves the messy wiring harness situation at the test site. The protective cover 5 can cover the battery 4 to provide protection and support for the battery 4, improve the stability and safety of the battery 4 on the infrared transmitting rod 2 and the infrared receiving rod 3, reduce safety hazards, and improve the convenience of powering the infrared transmitter 22 and the infrared receiver.

[0039] Reference Figure 1 、 Figure 2 The control panel is installed on the infrared receiving rod 3, and the control panel is electrically connected to the infrared transmitter 22 and the infrared receiver. The display panel is installed on the infrared receiving rod 3, and the display panel is electrically connected to the control panel; the signal light 6 is installed on the infrared transmitting rod 2, and the signal light 6 is electrically connected to the battery 4, and the signal light 6 is electrically connected to the control panel. In this embodiment, the signal light 6 is a multi-color light strip, so that the control panel can control the signal light 6 to light up different colors according to the measurement results, reminding the tester to check the measurement results.

[0040] The implementation principle of a standing long jump tester in an embodiment of the present application is as follows: a base plate 1 is arranged on an examination or sports field, and then an infrared receiving rod 3 and an infrared transmitting rod 2 are installed on the base plate 1 at intervals and in parallel, one end of the area between the infrared receiving rod 3 and the infrared transmitting rod 2 is set as the take-off area, and the remaining area between the infrared transmitting rod 2 and the infrared receiving rod 3 is set as the test area. The boundary line between the take-off area and the test area is the foul line, and the infrared transmitter 22 and the infrared receiver are turned on. The infrared transmitter 22 sends an electrical signal to the infrared receiver in the test area and the take-off area. The tester can stand in the take-off area and take off. If the tester steps on the foul line when taking off, the tester's footsteps will block the infrared light sent by the infrared transmitter 22 to the infrared receiver in the foul line area. The infrared receiver in the foul line area cannot receive the infrared signal and sends it to the control unit. The control panel sends an electrical signal, and after receiving the electrical signal, the control panel sends an electrical signal to the display panel and the signal light 6, so that the signal light 6 lights up and the display panel shows a foul; if the tester jumps normally in the jump zone, after the tester jumps to the test area, the tester's feet block the infrared rays sent by the infrared transmitter 22 in the test area, and the infrared receiver in the test area cannot receive the electrical signal, and then sends an electrical signal to the control panel, and the control panel sends an electrical signal to the display panel, and the display panel displays the nearest distance between the infrared rays that the infrared receiver cannot receive and the foul line, which is the tester's long jump distance. At the same time, the control panel controls the signal light 6 to light up, reminding the tester to check the long jump distance. The entire measurement process does not require manual measurement, calculation, and judgment of whether the line is stepped on, which effectively improves the accuracy and efficiency of measuring the standing long jump results.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
