Abstract
Portable long jump distance measuring device. When a player jumps far, the measurement is carried out through the cloth ruler, reading errors exist during measurement, meanwhile, since the position of the floor point deviating from the jumping board often appears after the player jumps on the sand pit, the measurement distance needs to be measured by finding the position parallel to the jumping board, and the measurement result is inaccurate. The utility model discloses the constitution includes: the laser ranging device comprises a steel tape (4), a T-shaped plate (2), a laser ranging sensor (1), a vertical plate (6), a sliding plate (7) and a bottom plate (8), wherein the laser ranging sensor is fixed at the horizontal end of the T-shaped plate, the steel tape is fixed on the vertical plate, a tape of the steel tape is fixed on the T-shaped plate, a positioning rod (5) is fixed at the upper end of the vertical plate, the bottom end of the vertical plate is fixed with the sliding plate, and the sliding plate is in sliding fit with the bottom plate. The utility model is used for portable long-jump distance measuring device.
Description
Technical Field
The utility model relates to a portable long-jump distance measuring device.
Background
When a player jumps far, the distance measurement of the long jump is the distance from the take-off board to the nearest point on the ground, the distance measurement is carried out by arranging a ruler, reading errors exist during measurement, meanwhile, the position of the landing point deviated from the take-off board often appears after the player jumps on a sand pit, but the long jump score is effective, so the distance measurement needs to find the position parallel to the take-off board for measurement, and the measurement result is inaccurate.
Disclosure of Invention
The utility model aims at providing a portable long-jump distance measuring device.
The above purpose is realized by the following technical scheme:
a portable long jump distance measuring device comprises a steel tape, a T-shaped plate, a laser distance measuring sensor, a vertical plate, a sliding plate and a bottom plate, wherein the laser distance measuring sensor is fixed at the horizontal end of the T-shaped plate, the steel tape is fixed on the vertical plate, a tape of the steel tape is fixed on the T-shaped plate, a positioning rod is fixed at the upper end of the vertical plate, the bottom end of the vertical plate is fixed with the sliding plate, and the sliding plate is in sliding fit with the bottom plate.
In the portable long jump distance measuring device, the center of the positioning rod is opposite to the through hole of the T-shaped plate.
Has the advantages that:
1. the utility model discloses can accurately measure long-jump distance through laser rangefinder sensor, reduce the error in the measurement.
2. The utility model discloses when the skew jump board's of long jump position, put the bottom plate on the jump board for the bottom plate aligns with the measurement end of jump board, and the riser slides and to carry out the long jump degree measurement of skew position this moment.
3. The utility model discloses set up the locating lever, the laser ray that jets out at laser rangefinder sensor shines and shows that riser and T shaped plate two are parallel to each other when the locating lever center, can guarantee measuring result's accuracy.
Description of the drawings:
FIG. 1 is a front view of the present invention;
fig. 2 is a top view of the present invention;
FIG. 3 is a schematic structural view of the present invention in use;
in the figure: 1. a laser ranging sensor; 2. a T-shaped plate; 3. a tape; 4. a steel tape; 5. positioning a rod; 6. a vertical plate; 7. a slide plate; 8. a base plate; 9. a chute; 10. a through hole; 11. a springboard.
The specific implementation mode is as follows:
example 1:
a portable long jump distance measuring device comprises a steel tape 4, a T-shaped plate 2, a laser distance measuring sensor 1, a vertical plate 6, a sliding plate 7 and a bottom plate 8, wherein the laser distance measuring sensor is fixed on the horizontal end of the T-shaped plate, the steel tape is fixed on the vertical plate, a tape 3 of the steel tape is fixed on the T-shaped plate, a positioning rod 5 is fixed at the upper end of the vertical plate, the bottom end of the vertical plate is fixed with the sliding plate, and the sliding plate is in sliding fit with the bottom plate.
Example 2:
according to the portable long jump distance measuring device of embodiment 1, the center of the positioning rod is opposite to the through hole 10 of the T-shaped plate.
The working principle is as follows: both ends have spout 9 about the bottom plate, the draw runner has on the slide, the draw runner is located the spout and carries out sliding fit, when using, align the bottom plate with the measuring end of springboard, the pulling T shaped plate makes the T shaped plate be in the nearest point of jumping pit, put the T shaped plate back, the red light spot that makes laser rangefinder sensor send shines in the center department of locating lever, the distance is the long-range jump degree this moment, when the position deviation springboard 11 of long-range jump, slide, remove the T shaped plate simultaneously and make its position at the measuring point, then carry out the measurement of long-range jump degree.
Claims (2)
1. A portable long jump distance measuring device is characterized in that: the laser ranging device comprises a steel tape, a T-shaped plate, a laser ranging sensor, a vertical plate, a sliding plate and a bottom plate, wherein the laser ranging sensor is fixed at the horizontal end of the T-shaped plate, the steel tape is fixed on the vertical plate, a tape of the steel tape is fixed on the T-shaped plate, a positioning rod is fixed at the upper end of the vertical plate, the bottom end of the vertical plate is fixed with the sliding plate, and the sliding plate is in sliding fit with the bottom plate.
2. The portable long jump distance measuring device of claim 1, wherein: the center of the positioning rod is opposite to the through hole of the T-shaped plate.
