Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of bow and arrow, specifically relates to a wheel group used in cooperation with competition steel ball. BACKGROUND

[0002] At present, the shooting mode of bow and arrow has two kinds, one is to shoot with arrow, and the other is to shoot with steel ball. When shooting with steel ball, the steel ball seat used for shooting with steel ball is arranged on the bowstring.

[0003] The interval of the two main wheel grooves of the existing wheel group is about 10mm, the interval of the two main strings is also about 10mm, and the diameter of the competition steel ball is 14mm or 15mm. Since the diameter of the steel ball is greater than the interval of the two main strings, the steel ball cannot be located between the two main strings. Based on this, in order to cooperate with the use of the existing wheel group, the existing steel ball seat needs to use a front-mounted steel ball seat, that is, the steel ball needs to be placed in front of the two main strings, and the string is pulled to launch the steel ball through the front-mounted steel ball seat.

[0004] However, after a long period of use, it is found that the existing wheel group and the existing steel ball seat have the following problems: since the steel ball is placed on the front-mounted steel ball seat, the center of the steel ball and the center line of the two main strings are not coincident, so when the front-mounted steel ball seat rotates after pulling the string, the center of the steel ball will rotate relatively greatly, which will affect the trajectory of the steel ball, resulting in a large error when shooting with steel ball and affecting the final shooting result.

[0005] Based on the above problems, we design a wheel group used in cooperation with competition steel ball. CONTENT OF THE UTILITY MODEL

[0020] Mark explanation: wheel group main wheel 1, main wheel groove 101, competition steel ball 2, steel ball seat 3, chord groove 301. DETAILED DESCRIPTION

[0021] The utility model discloses a kind of wheel groups for cooperation competition steel ball, as shown in

[0022] Example 1

[0023] A wheel group for cooperation competition steel ball, as shown in Figure 1As shown, the wheel set main wheel 1 is provided with two main wheel grooves 101, and one main string 4 is wound in each of the two main wheel grooves 101. The steel ball seat 3 (the specific structure can be referred to the disclosure of patent No. CN220670324U) is provided with two string grooves 301, and the two string grooves 301 are respectively clamped and fixed on the two main strings 4.

[0024] As the scale parameter setting, the distance between the two main wheel grooves 101 of the wheel set main wheel 1 is A, the distance between the two main strings 4 suspended in the middle of the two main wheel grooves 101 is B, the distance between the inner sides of the two string grooves 301 of the steel ball seat 3 is C, and the diameter of the competition steel ball 2 is D.

[0025] As the scale parameter ratio improvement, the wheel set main wheel 1 and the steel ball seat 3 are hard materials and will not deform, the two main strings 4 are soft materials and will deform, the size change of the distance B is caused by the change of the distance A or the distance C, and in actual use, the distance A is greater than or equal to the distance B or the size of the distance A is less than the distance B by 1mm, the distance B is greater than or equal to the distance C or the distance B is less than the distance C by 1mm, and the distance C is greater than or equal to the diameter D.

[0026] The scale parameter ratio improvement can make the competition steel ball 2 placed in the middle of the steel ball seat 3, and at the same time make the steel ball seat 3 placed in the middle of the two main strings 4, so as to ensure that the center of the steel ball coincides with the center line of the two main strings. Therefore, when the front-mounted steel ball seat rotates after the string is pulled, the center of the steel ball always coincides with the center line of the two main strings, so as not to affect the trajectory of the steel ball, ensure the center accuracy of the steel ball, and improve the competition shooting result.

[0027] Embodiment 2

[0028] As an optimization of embodiment 1, the diameter of the competition steel ball 2 is the same standard, and the diameter D is 14mm. Based on the consideration of the diameter of the competition steel ball 2, the inner side distance C of the string groove 301 is 16mm. At the same time, considering that the two main strings 4 are soft materials and will deform, the distance B will be less than the distance C by 1mm, so the distance B of the two main strings 4 suspended in the air is 15mm. Because the installation position of the steel ball seat 3 on the two main strings 4 is at least 10cm away from the wheel set string groove 301, the two main strings 4 at this position have a certain elasticity, and the size of the distance A is less than the distance B by 1mm, which can also ensure normal shooting, so the distance A of the two main wheel grooves 101 can be 14mm.

Because the installation position of the steel ball seat 3 on the two main chords 4 is at least 10 cm away from the wheel group chord groove 301, the two main chords 4 at this position have a certain elasticity, and the distance A is less than the distance B within 1 mm, which can also ensure normal shooting, so the distance A of the two main wheel grooves 101 can be 15 mm.
