Description

Technical Field

[0001] This utility model relates to the field of body measurement technology, and in particular to a portable body measurement device. Background Technology

[0002] Physical fitness tests are often used to assess physical fitness and evaluate an individual's physical condition. The long jump mainly tests the speed, strength, skill, and coordination of the test taker. The test taker jumps as far as possible by running, taking off, and soaring through the air, or by standing long jump. During the long jump, it is usually necessary to measure the distance of each jump and record the results of the physical fitness test.

[0003] However, most existing long jump measuring devices are actually used with measuring tapes or tape measures. But because each long jump needs to be measured, and the measurement process can easily damage the jump position, the measurement is not accurate enough. At the same time, the repeated extension and retraction of the measuring tape also makes it quite inconvenient to use. There are also some special venues, such as the Chinese patent announced on December 15, 2023, announcement number CN220176006U, which discloses a sports long jump measuring device with scales set on the ground. However, this method is relatively limited and cannot be carried around or used in different venues. Summary of the Invention

[0004] The technical effect of this utility model can solve the above problems and propose a portable body measurement device, which can improve the convenience and accuracy of body measurement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The portable body measurement device of this utility model includes a base, a fixed seat is fixedly installed on the upper side of the base, the fixed seat is hinged to a sliding rod through a limiting device, the upper and lower surfaces of the sliding rod are provided with scale lines, the sliding rod is provided with a movable plate and a sliding mechanism for the movable plate to slide along the sliding rod, a connecting cylinder and a battery box are fixedly installed on one side of the movable plate, a laser head is provided on the connecting cylinder, the laser head is electrically connected to a battery provided in the battery box, and a mounting box is provided on the upper side of the base, and the measuring device is provided in the mounting box.

[0006] By using the sliding bar, it is easy to rotate the bar to the left or right ends of the base during use. Combined with the sliding setting of the moving plate, the laser head can be pointed at the long jump position. The final value can then be read from the sliding bar, which improves the convenience and accuracy of long jump measurement.

[0007] Preferably, the sliding mechanism includes a sliding groove, a moving groove, and a pulley. The sliding groove is located on one side of the sliding rod, and the moving groove is located on the side where the moving plate contacts the sliding rod. A slider is provided on the inner side wall of the moving groove, and the pulley is provided on the slider. Slide plates are provided at the upper and lower ends of the moving groove. The slide plates are locked on the scale lines on the upper and lower surfaces of the sliding rod, and the moving plate slides along the sliding groove via the pulley.

[0008] Preferably, both the upper and lower surfaces of the skateboard are equipped with observation ports, the center of which corresponds to the center of the laser head. The position of the scale line on the skateboard seen through the observation port is the position of the laser head, which is also the landing position of the long jumper.

[0009] Preferably, the limiting device includes a turntable, a connecting shaft, and a limiting plate. A limiting block protruding from the surface of the limiting plate is fixedly connected to the limiting plate. One end of the sliding rod is fixedly connected to the turntable, and the turntable is fixedly connected to the limiting plate via the connecting shaft. A circular groove is formed inside the fixed base, and both the connecting shaft and the limiting plate are disposed within the circular groove. A semi-circular arc-shaped limiting ring is provided on the inner wall of the circular groove, allowing the limiting block to rotate semi-circularly within the circular groove and the arc-shaped limiting ring. A first cover plate is installed on the outer surface of the circular groove. The limiting device ensures that the sliding rod can only swing approximately 180° on the horizontal plane of the base, resulting in more accurate readings.

[0010] Preferably, each of the four corners of the base is fixedly connected to a connecting column, and each connecting column is equipped with an adjusting bolt. Two mounting seats are fixedly connected to the upper side of the base, each with a spirit level. By adjusting the adjusting bolts, the spirit level is centered, ensuring the base is level and improving the accuracy of the measurement results.

[0011] Preferably, a handle is fixedly connected to the upper side of the base to facilitate carrying or moving the measuring device.

[0012] Preferably, the base has a rod on its lower side. When measuring on grass or sand, the rod can be inserted into the ground to stabilize the measuring device. During the test, the measuring device will not shake or move, thereby improving the accuracy of the measurement results.

[0013] Preferably, both sides of the slide bar are provided with removable plugs, which facilitates the removal of the moving plate for maintenance or replacement of the laser head battery.

[0014] Preferably, the measuring mechanism includes a measuring tape, which is disposed inside a mounting box; a vertical groove is provided on one side of the mounting box, through which the measuring tape extends and retracts; an indicator arrow is provided on the upper side of the mounting box.

[0015] The beneficial effects of this utility model are as follows: 1. During measurement, the top slide can be manually slid to move the moving plate along with it. The laser head will then open, and the line of light emitted by the laser head will be vertical. This allows the laser head to be aligned with the landing position of the long jump. The reading can then be taken by observing the scale lines on the slide bar through the observation port on the top slide. This makes the long jump measurement results faster and improves the ease of use of the device.

[0016] 2. When the long jump position is outside the measurement range, a measuring tape can be pulled out for measurement. In this case, the distance measured by the measuring tape should be added to the distance between the device and the take-off position to improve the effectiveness of the device.

[0017] 3. When using this device, it is not necessary to measure with a measuring tape after each long jump, which greatly improves the convenience of long jump measurement. At the same time, the device aligns the measurement position with the line of the laser head, without damaging the position after the long jump, thereby improving the accuracy of the final measurement result.

[0018] 4. The device has a handle, making it easy to carry during use, thus improving its portability. Attached Figure Description

[0026] The measuring mechanism of this utility model can be either a commercially available ordinary measuring tape or a measuring ruler with the following structure: In this utility model, the measuring mechanism includes a measuring tape 6. A vertical groove 51 is vertically opened on the side of the mounting box 5 away from the fixed base 2. A winding reel 61 is rotatably connected inside the mounting box 5. The measuring tape 6 is set on the outer surface of the winding reel 61. One end of the measuring tape 6 passes through the vertical groove 51 and the other end is set outside the mounting box 5. A fixed post 52 is vertically fixedly connected at the center of the mounting box 5. The winding reel 61 is rotatably sleeved on the outer surface of the fixed post 52. A threaded spring piece 63 is set at the bottom of the mounting box 5. One end of the threaded spring piece 63 is fixedly connected to the surface of the fixed post 52. The threaded spring piece 63 is set inside the winding reel 61 and the other end is fixedly connected to the surface of the winding reel 61. It is used to stretch or wind up the measuring tape 6, so as to facilitate the placement of the base 1 in a designated position.

[0027] In this invention, a second cover plate 54 is installed on the top of the mounting box 5. An indicator arrow 55 is horizontally opened on the surface of the second cover plate 54, corresponding to the measuring tape 6. Multiple arc-shaped baffles 62 are fixedly connected to the inner wall of the take-up reel 61 near the top. A pressing post 7 is vertically slidably connected to the center of the take-up reel 61, passing through the surface of the second cover plate 54. A limiting ring 71 is sleeved on the outer surface of the pressing post 7, located at the bottom of the second cover plate 54 and the take-up reel itself. Inside 61, two stop bars 72 are horizontally fixedly connected to the outer surface of the limiting ring 71. Both stop bars 72 cooperate with multiple arc-shaped baffles 62. One side of the surface of both stop bars 72 is inclined. A spring 53 is installed inside the fixing post 52. The pressing post 7 is vertically slidably sleeved on the outer surface of the fixing post 52.

The two stop bars 72 can restrict the multiple arc-shaped baffles 62, which facilitates the winding of the stretched tape measure 6.

[0028] Working principle: When using the device, it needs to be placed in the designated position. First, pull out the measuring tape 6 on the surface of the mounting box 5 on the device to measure the distance between the device and the long jump take-off position. For example, if the distance between the take-off position and the center position of the device is two meters, then place the device in this position. During use, the sliding rod 3 can be rotated. Under the action of the limiting block 38, the rotation range of the limiting plate 37 will be limited, and the rotation position of the sliding rod 3 will also be limited to a horizontal state. During measurement, the top sliding plate 44 can be manually slid to move the moving plate 4 together, opening the laser head 42 so that the line illuminated by the laser head 42 is vertical. This allows the position illuminated by the laser head 42 to be aligned with the final landing position of the long jump. Then, observe the scale line 31 (30cm in length) on the surface of the sliding rod 3 through the observation port 45 to take the reading. When the sliding rod 3 is rotated away from the take-off position, the scale line 31 on the surface of the sliding rod 3 is between 2m and 2.3m; when the sliding rod 3 is rotated closer to the take-off position, the scale line 31 on the surface of the sliding rod 3 is between 1.7m and 2m. This method eliminates the need for measurement with a measuring tape after each long jump, improving the ease of use of the device. When the long jump position exceeds the measurement range, the measuring tape 6 can be extended for measurement (e.g., at the 2.5m position) or shortened for measurement (e.g., at the 1.5m position).
