Description

Technical Field

[0001] The present invention relates to the field of competitive sports technology, and more particularly to a bow and arrow centerline detector for calibrating bow and arrow accuracy and a calibration detection method thereof. Background Art

[0002] Archery, or archery, is a sport that uses the elastic force of a bow to shoot arrows and compete for accuracy within a certain distance. It is also known as archery. As early as 10,000 years ago in the Middle Stone Age, humans invented bows and arrows for hunting and fishing. Later, bows and arrows were one of the weapons used in war. Now, archery exists as a favorite sport. The origin of archery can be traced back to about 50,000 BC. It was once popular in ancient Africa, Europe, Asia and other regions. China invented bows and arrows as early as the late Paleolithic Age. Bows and arrows have always been an important weapon for people to hunt and the army to fight. Modern archery originated in Britain in the 14th century. It evolved from the military needs of warriors to an entertainment activity. In the 16th century, three forms of archery appeared: the first is target archery, the second is ground target archery, and the third is roaming archery. The three important world archery championships are: the World Outdoor Archery Championships, the World Indoor Archery Championships and the World Field Archery Championships.

[0003] The bows and arrows used by archers are the result of the latest modern technology and have excellent performance. The bow can be equipped with a sight, and it is allowed to install a stabilizer or an arrow flight shock absorber, but it is not allowed to be used for string drawing and aiming, and it cannot touch other objects. Generally speaking, modern bows can be divided into compound bows and recurve bows. A recurve bow is mainly composed of a bow handle, bow limbs, sights, signal pieces, arrow rests, and a balance rod (V-shaped seat, extension rod, push handle, long rod, side rod).

[0004] Due to the high accuracy requirements for archery, the manufacturing accuracy requirements for bows are also very high. If the bow back cannot be in a straight line but is bent, it will have a great impact on the accuracy of archery.

[0005] Therefore, how to provide a bow and arrow centerline detector and a calibration detection method thereof that can accurately and conveniently calibrate and test the bow back accuracy is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] In view of this, the present invention provides a bow and arrow centerline detector, aiming to solve the above technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A bow and arrow centerline detector, comprising: a box body, a laser tube and an electric control component;

[0009] A straight fixing groove for clamping the bowstring is provided on one side edge of the box body; a snap clamp for clamping the bowstring in the fixing groove is hingedly installed on the surface of the box body close to the fixing groove;

[0010] The number of the laser tubes is three and they are fixedly embedded in the box body. The emission ports of the three laser tubes are in the same horizontal plane as the fixing groove and face the outside of the box body and away from the fixing groove.

[0011] The electric control component is installed inside the box body and is used to supply power to the laser tube.

[0012] Through the above technical scheme, the tester provided by the present invention is used to detect whether the back of the bow is in a straight line. The tester uses three laser tubes to emit lasers at different azimuth angles to determine whether they can coincide with the corresponding calibration points on the back of the bow to complete the calibration test. The tester is simple and convenient to use and has high calibration accuracy.

[0013] Preferably, in the above-mentioned bow and arrow centerline detector, among the three laser tubes: two of the laser tubes are arranged back to back, and the central axes coincide and are parallel to the fixing groove; the axis extension line of the remaining laser tube is at an angle to the fixing groove, which can meet the calibration detection requirements.

[0014] Preferably, in the above-mentioned bow and arrow centerline detector, the angle formed by the laser tube and the fixing groove is between 45° and 135°, so as to prevent position interference between the laser tubes and meet the calibration detection requirements.

[0015] Preferably, in the above-mentioned bow and arrow centerline detector, the electric control assembly includes a lithium battery, a circuit board, a switch button and a USB charging port; the lithium battery is fixedly embedded in the box body and electrically connected to the laser tube; the circuit board is fixedly embedded in the box body and electrically connected to the lithium battery; the switch button is fixed on the circuit board and electrically connected to the circuit board and exposed on the surface of the box body; the USB charging port is fixed on the circuit board and electrically connected to the circuit board and exposed on the side wall of the box body. It is easy to control the power supply and convenient to charge.

[0016] Preferably, in the above-mentioned bow and arrow centerline detector, the electric control component further comprises a power indicator light fixed on the circuit board, the power indicator light is electrically connected to the circuit board and exposed on the surface of the box body, so as to facilitate the determination of the power status.

[0017] Preferably, in the above-mentioned bow and arrow centerline detector, the box body is a flat structure, which is convenient for gripping and using.

[0018] Preferably, in the above-mentioned bow and arrow centerline detector, the box body is a structure that can be split up and down, so as to facilitate the installation and fixation of the structure inside the box body.

[0019] The present invention also provides a calibration detection method for a bow and arrow centerline detector, comprising the following steps:

[0020] S1, turn on three laser tubes through the electronic control components;

[0021] S2, open the trigger clamp, clamp the bowstring in the fixed groove, and move the box body in the direction of the bowstring, or rotate with the bowstring as the axis, when the laser emitted by a laser tube irradiates the corresponding calibration point on the back of the bow, the trigger clamp clamps the bowstring;

[0022] S3. Judge the calibration test results: if the lasers emitted by the three laser tubes are all irradiated on the corresponding calibration points on the bow back, the bow back calibration test is qualified; if the lasers emitted by one or two of the three laser tubes are not irradiated on the corresponding calibration points on the bow back, the bow back calibration test is unqualified.

[0023] Through the above technical scheme, in the process of calibrating and detecting the bow back, the present invention only needs to find a laser tube corresponding to the corresponding calibration point, and then the box body can be clamped on the bowstring by a button clamp to perform calibration detection and judgment. The operation is simple and convenient, and the calibration accuracy is high.

[0024] Preferably, in the calibration detection method of the bow and arrow centerline detector, in S2, the box is first clamped in the center of the bowstring and then adjusted, which is conducive to quickly aligning a laser tube.
