Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, in particular to a measuring ruler for long jump. Background Art

[0002] Long jump is a jumping event in track and field. It consists of a combination of running-up, take-off, aerial and landing. The athlete runs in a straight line, takes off with one foot behind the front line of the take-off board, goes through the aerial stage, and then lands in the sand pit with both feet. Finally, the referee or surveyor measures the long jump distance, which is generally measured with a measuring ruler.

[0003] At present, when measuring the long jump distance, a tape measure is used to measure directly, and two people are required to cooperate. However, the sand in the sand pit may be higher than the ground, which may cause the tape measure to bend during the measurement, thereby possibly affecting the accuracy of the long jump distance measurement. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a measuring ruler for long jump which can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A measuring ruler for long jump comprises: a measuring box, and also comprises: a telescopic sleeve rotating in the measuring box; a distance sensor fixed in the measuring box, and the distance sensor matches the end of the telescopic sleeve; a connecting plate fixed to the end of the telescopic sleeve away from the measuring box; a thin rod fixed on the connecting plate; a measuring block arranged on the thin rod; a fitting plate fixed on the measuring block; a first control button arranged on the measuring block; and a controller arranged in the measuring box.

[0007] Preferably, the measuring block slides on the thin rod.

[0008] In order to prevent frequent bending operation, further, a rotating rod is rotatably provided on the measuring block.

[0009] In order to facilitate obtaining the measurement results, further, a second control button is provided on the rotating rod.

[0010] Preferably, a mounting plate is provided on the lower side of the measuring box, and threaded holes are symmetrically provided on the mounting plate.

[0011] In order to facilitate installation and disassembly of the measuring box, further, a plurality of slots are provided on the measuring box, a plurality of insertion rods matching the slots are fixedly connected to the mounting plate, and the insertion rods slide in the slots.

[0012] Compared with the prior art, the utility model provides a measuring ruler for long jump, which has the following beneficial effects:

[0013] 1. The measuring ruler for long jump is configured by rotating the thin rod to the sand pit area, then sliding the measuring block so that the bonding plate on the measuring block contacts the point to be measured, and the point to be measured coincides with the end face of the bonding plate, and pressing the first control button. At this time, the controller receives the data signal measured by the distance sensor at this time, and then transmits the data to the staff's mobile phone or to an external microcomputer for recording. The setting of the thin rod can effectively prevent the sand in the sand pit from affecting the measurement result, thereby effectively improving the accuracy of the long jump distance measurement.

[0014] 2. The long jump measuring ruler adopts a fixed measuring box matched with a telescopic sleeve, can be operated by one person, and effectively improves the efficiency of long jump distance measurement.

[0015] 3. The long jump measuring ruler is operated by rotating the rod, thereby effectively preventing the staff from bending over frequently and overworking. When obtaining the measurement result, the second control button is pressed, and the first control button and the second control button are set the same.

[0016] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. The utility model effectively prevents the sand in the sand pit from affecting the measurement result, thereby effectively improving the accuracy of the long jump distance measurement.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1: Reference Figure 1-Figure 4 A measuring ruler for long jump, comprising: a measuring box 1, and also comprising: a telescopic sleeve 101, which rotates in the measuring box 1; a distance sensor 102, which is fixed in the measuring box 1, and the distance sensor 102 matches the end of the telescopic sleeve 101; a connecting plate 2, which is fixed to the end of the telescopic sleeve 101 away from the measuring box 1; a thin rod 201, which is fixed on the connecting plate 2; a measuring block 202, which is arranged on the thin rod 201; a fitting plate 203, which is fixed on the measuring block 202; a first control button 204, which is arranged on the measuring block 202; and a controller 107, which is arranged in the measuring box 1.

[0024] The measuring block 202 slides on the thin rod 201 .

[0025] A rotating rod 205 is rotatably provided on the measuring block 202 .

[0026] A second control button 206 is disposed on the rotating rod 205 .

[0027] When measuring the long jump length, first install the measuring box 1 at the starting point, then pull out the telescopic sleeve 101, and rotate the thin rod 201 to make the connecting plate 2 and the thin rod 201 away from the long jump area. At this time, the thin rod 201 can be in a vertical state or tilted to the side away from the sand pit.

[0028] When the long jumper finishes the long jump, he rotates the thin rod 201 to the sand pit area, and then slides the measuring block 202 to make the bonding plate 203 on the measuring block 202 contact the point to be measured, and make the point to be measured coincide with the end face of the bonding plate 203, and press the first control button 204. At this time, the controller 107 receives the data signal measured by the distance sensor 102 at this time, and then transmits the data to the staff's mobile phone or to an external microcomputer for recording. Through the setting of the thin rod 201, the sand in the sand pit can be effectively prevented from affecting the measurement result, thereby effectively improving the accuracy of the long jump distance measurement.

[0029] The fixed measuring box 1 cooperates with the telescopic sleeve 101, which can be operated by one person and effectively improves the efficiency of long jump distance measurement.

[0030] When rotating or moving the thin rod 201, the operation is performed by rotating the rod 205, thereby effectively preventing the staff from bending over frequently and overworking. When obtaining the measurement result, the second control button 206 is pressed. The first control button 204 and the second control button 206 are set the same.

[0031] Example 2: Reference Figure 1-Figure 4 , a measuring ruler for long jump, which is basically the same as that of embodiment 1, further, a mounting plate 104 is provided on the lower side of the measuring box 1, and threaded holes 105 are symmetrically provided on the mounting plate 104.

[0032] The measuring box 1 is provided with a plurality of slots 103 , and a plurality of insertion rods 106 matching the slots 103 are fixedly connected to the mounting plate 104 , and the insertion rods 106 slide in the slots 103 .

[0033] By installing a mounting plate 104 on one side of the long jump location, inserting expansion screws into the ground, and then fixing the mounting plate 104 to the ground with bolts, the measuring box 1 is placed on the mounting plate 104, and the insertion rod 106 is placed in the slot 103 to limit the measuring box 1. When the measurement is completed, the measuring box 1 is directly removed, thereby facilitating the removal of the measuring box 1 and preventing it from being damaged by wind and sun for a long time outdoors.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
