Abstract
A measuring instrument for long jump belongs to the technical field of sports equipment and comprises a bottom plate, a left-side laser plate axially connected with one side of the bottom plate, a right-side scale plate axially connected with the other side of the bottom plate, wherein a groove is arranged on the left-side laser plate, a laser pen perpendicular with the left-side laser plate and facing the right-side scale plate is arranged in the groove; a laser plate housing groove is arranged on one surface of the right-side scale plate backing to the left-side laser plate, and a layer of a thin sheet with scales is adhered on one surface of the right-side scale plate facing the left-side laser plate. Furthermore, the bottom plate, the left-side laser plate and the right-side scale plate are unfolded into a U shape by a fixation rack, and folded into a '-' shape. Compared with the prior art, the material is simple and easy to obtain, the laser pen is moved, thus the long jump location point, the position of the laser pen and the position of the right-side scale plate with scales are arranged in the same line, therefore the measuring instrument is accurate, quick and convenient to operate by the laser measurement, thus the measuring instrument is a physical exercise measurement tool easy to transform.
Description
Technical field
The utility model relates to a kind of utensil of gym survey, is the long-jump measuring instrument specifically.
Background technology
Promote physical culture and build up the people's health.Healthy physique has only been arranged, could be competent at better study and work, particularly in school, sports more should be strengthened.Long-jump, needs to measure the length that the student jumps as traditional project in quantification, and traditional way is directly to use tape measuring, and error is larger, and inconvenience does not also have special articles for use at present.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of energy fast and simple long-jump measuring instrument.
The purpose of this utility model realizes by following technological means: the long-jump measuring instrument, comprise base plate, and described base plate one side is connected with the left side Laser Slabs by axle, and opposite side is connected with the right side scaleplate by axle;
The left side Laser Slabs has a groove above the Laser Slabs of described left side, is placed with one in groove perpendicular to the left side Laser Slabs and towards the laser pen of right side scaleplate;
Right side scaleplate, described right side the scaleplate one side of left side Laser Slabs dorsad are provided with Laser Slabs and take in groove, post the thin slice of one deck band scale mark towards the one side of left side Laser Slabs.
Further, base plate, left side Laser Slabs and right side scaleplate are launched into " U " type by fixed mount, close up rear one-tenth " one " type; Expansion can be measured the length of long-jump, can be used as height gauge after closing up and measures height or other length, achieves many things at one stroke.
Compared with prior art, the utility model is drawn materials and is simple and easy to, by mobile laser pen, with long-jump touchdown point, laser pen and with sight alignment between the right side scaleplate of scale, utilize laser measurement, accurately, quick, convenient operation is a kind of physical training survey instrument that is easy to transform.
Description of drawings
Fig. 1 is the utility model overall schematic;
1. base plates wherein, 2. left side Laser Slabs, 20. grooves, 21. laser pens, 3. right side scaleplate, 30. Laser Slabs are taken in groove, 31. scale marks, 4. axle, 5. fixed mount.
Embodiment
Below in conjunction with description of drawings, the utility model is described in further detail:
This long-jump with the use procedure of measuring instrument is: base plate 1 is positioned on the scratch line of long jump runway, launches left side Laser Slabs 2 and 3 one-tenth of right side scaleplates " U " type, and three battens are met at right angles between any two, and fixing with fixed mount 5.After long-jump, find out touchdown point, by the laser pen 21 in mobile groove 20, make long-jump touchdown point, laser pen 21 and with sight alignment between the right side scaleplate 3 of scale mark 31, Ear Mucosa Treated by He Ne Laser Irradiation to scale be the length that long-jump person jumps.
Finish using, fixed mount 5 is extracted, close up left side Laser Slabs 2 and 3 one-tenth of right side scaleplates " " type, both can measure height, also be convenient to deposit.
In a word, the utility model provides the long-jump measuring instrument.The above; it is only a part of embodiment of the present utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.
