Detailed Implementation
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0021] See Figures 1-3 This embodiment provides an adjustable bow handle structure, including a bow handle post 1 and movable blocks 2 for fixing the bow limbs. There are two movable blocks 2, which are respectively located at the upper and lower ends of the bow handle post 1. Multiple mounting holes 11 of different heights are opened at the upper and lower ends of the bow handle post 1, and the two movable blocks 2 are respectively adapted and fixed on the mounting holes 11 at the corresponding positions.
[0022] This invention allows for height adjustment of the movable block 2 by installing it on mounting holes 11 at different heights. Since the bow piece is installed on the movable block 2, the bow handle length can be adjusted to adjust the bow handle specifications. This invention can meet the needs of multiple bow handles of different specifications, reducing the number of bow handles that users need to purchase, thereby reducing the purchase cost and storage management complexity of bow handles.
[0023] During use, the user's hand is usually held in the middle of the bow handle, with the arrow positioned above the hand. At this time, the arrow's position is slightly higher than the center of symmetry of the bow handle post 1, resulting in uneven force on the arrow from the bowstring and affecting the arrow's shooting accuracy. Therefore, in this invention, the height of the two movable blocks 2 can be adjusted separately, so that the two movable blocks 2 are asymmetrically positioned relative to the bow handle post 1. This adjusts the center of the bowstring to coincide with the tail of the arrow, making the force on the arrow more uniform and improving the arrow's shooting accuracy.
[0024] See Figure 1 The front and rear sides of the bow handle post 1 at the middle position can be detachably fixed with pads 12.
[0025] The pad 12 increases the thickness of the grip area of the bow handle 1, thereby improving the grip feel and comfort. During use, the pad 12 acts as an arrow rest, improving the stability of the arrow's trajectory.
[0026] See Figures 1-3The movable block 2 has a first through hole 21 on both the front and rear sides. A slider 22 is provided between the movable block 2 and the bow handle post 1. The left end of the slider 22 abuts against the bow handle post 1. A sliding groove 23 is provided inside the movable block 2. The right end of the slider 22 slides up and down in the sliding groove 23. A spring 24 is provided between the bottom end of the slider 22 and the sliding groove 23. An internal thread section 25 is provided inside the sliding groove 23 and an adjusting screw 26 is provided through a threaded connection. The inner end of the adjusting screw 26 and the spring 24 abut against the inner and outer sides of the slider 22, respectively.
[0027] When the movable block 2 is installed on the bow handle post 1, firstly, select the mounting hole 11 of the corresponding height according to the usage requirements. Use bolts to pass through the two first through holes 21 at the front and rear and the mounting hole 11, so that the movable block 2 can rotate around the bolt as the axis. After the bow plate is installed on the movable block 2 and the bow string is connected to the bow plate, the force of the bow string and the bow plate will drive the movable block 2 to have a counterclockwise rotation tendency (as shown in Figure 3). This causes the left end of the slider 22 to abut against the bow handle post 1. The user can turn the adjusting screw 26, which moves up and down under the action of the internal thread section 25. Since the spring 24 drives the slider 22 to always abut against the adjusting screw 26, when the adjusting screw 26 moves up and down, the slider 22 moves up and down accordingly, causing the movable block 2 to rotate to the left or right relative to the bow handle post 1, thereby adjusting the angle between the movable block 2 and the bow handle post 1. Finally, use the nut and bolt to tighten and clamp the movable block 2 to the front and rear sides of the bow handle post 1, thus fixing the movable block 2 to the bow handle post 1.
[0028] When the movable block 2 rotates to the right relative to the bow handle post 1, it increases the angle of rightward deflection of the bow limbs. This increases the deformation of the bow limbs after connecting the bowstring, thereby increasing the elastic potential energy stored in the bow limbs and the bow's draw weight at the same draw length, thus improving the bow limbs' efficiency and the bow's draw weight. Conversely, when the movable block 2 rotates to the right relative to the bow handle post 1, it decreases the elastic potential energy stored in the bow limbs and the bow's draw weight at the same draw length (e.g., ...). Figure 3 (As shown in the diagram). Users can adjust the bow's draw weight by adjusting the angle between the movable block 2 and the bow handle post 1 according to their needs.
[0029] In this invention, the outer end of the adjusting screw 26 is provided with a cross-shaped groove or an internal hexagonal groove, which facilitates the movement of the adjusting screw 26 within the slide groove 23. The adjusting screw 26 can use a ball spring 24 screw to achieve a certain effect of shock absorption and superimposed elastic potential energy.
[0030] See Figure 1 , Figure 2The movable block 2 is provided with several second through holes 27 on both the front and rear sides. The centers of the several second through holes 27 are all located on the same circular trajectory and the center of the circular trajectory coincides with the center of the first through hole 21. When the first through hole 21 and one of the mounting holes 11 are aligned front and rear, the second through holes 27 are located on the front and rear sides of the other mounting hole 11.
[0031] In this invention, by aligning different second through holes 27 with mounting holes 11 and locking them with bolts, the fixed angle between the movable block 2 and the handlebar post 1 can be adjusted to multiple levels. Finally, the movable block 2 is clamped and fixed to the front and rear sides of the handlebar post 1 by tightening the nuts and bolts, thus fixing the movable block 2 and the handlebar post 1.
[0032] Therefore, after adjusting the angle between the movable block 2 and the handlebar post 1 using the adjusting screw 26, if there happens to be a second through hole 27 aligned with the mounting hole 11, then the bolt is directly inserted into the second through hole 27 and the mounting hole 11 and fixed with a nut to achieve the fixation between the movable block 2 and the handlebar post 1. This fixing method is relatively stable and can prevent the angle between the movable block 2 and the handlebar post 1 from changing during use.
[0033] See Figure 1 , Figure 2 The movable block 2 is provided with arc-shaped holes 28 on both the front and rear sides. The center of the circle where the arc-shaped hole 28 is located coincides with the center of the first through hole 21. When the first through hole 21 and one of the mounting holes 11 are aligned front and rear, the arc-shaped hole 28 is located on the front and rear sides of the other mounting hole 11.
[0034] In this invention, the arc-shaped hole 28 allows the angle between the movable block 2 and the handlebar post 1 to be freely adjusted within a certain range. Finally, bolts are passed through the arc-shaped hole 28 and the mounting hole 11, and nuts are tightened to clamp and fix the movable block 2 to the front and rear sides of the handlebar post 1, thus achieving the fixation of the movable block 2 to the handlebar post 1. This invention has multiple arc-shaped holes 28, which, through multiple bolts and nuts, improve the stability of the fixation between the movable block 2 and the handlebar post 1.
[0035] Therefore, after adjusting the angle between the movable block 2 and the handlebar post 1 using the adjusting screw 26, if all the second through holes 27 are not aligned with the mounting holes 11, and it is impossible to fix the movable block 2 and the handlebar post 1 by inserting bolts into the second through holes 27, then bolts are used to pass through the arc-shaped hole 28 and the mounting hole 11 and are tightened with nuts to drive the movable block 2 to be clamped on the handlebar post 1, thereby fixing the movable block 2 and the handlebar post 1. This fixing method allows the angle between the movable block 2 and the handlebar post 1 to be freely adjusted within a certain range, thereby improving the applicability of this utility model.
[0036] In summary, among the two methods of fixing the movable block 2 and the handlebar post 1, if the condition that a second through hole 27 is aligned with the mounting hole 11 is met, the second through hole 27 should be used for fixing to improve the stability of the fixing. If the condition that the second through hole 27 is aligned with the mounting hole 11 is not met, the arc-shaped hole 28 should be used for fixing to increase the adjustable range of the angle between the movable block 2 and the handlebar post 1.
[0037] See Figure 2 Several gaskets 4 are provided between the front and rear sides of the bow handle post 1 and the contact surface of the movable block 2. The gaskets 4 are fixed inside the movable block 2. The gaskets 4 are provided with insertion holes 41 with the same shape as the first through hole 21, the second through hole 27 and the arc-shaped hole 28.
[0038] The shim 4 acts as a buffer between the handlebar post 1 and the movable block 2, improving the shock absorption effect of the handlebar and reducing frictional wear between the handlebar post 1 and the movable block 2 during use, thus extending the service life of this invention. Simultaneously, the shim 4 can deform to increase the tightness of the contact surface with the handlebar post 1 and the movable block 2, thereby increasing static friction and reducing the probability of the movable block 2 rotating on the handlebar post 1 during use, thus improving the stability of the movable block 2. The insertion hole 41 on the shim 4 is used for bolt insertion, ensuring that the movable block 2 and the handlebar post 1 can be fixed with bolts.
[0039] Because recurve bows are held with either the left or right hand depending on the user's preference, and the forward and backward offset of the bow limbs differs depending on whether the bow is held with the left or right hand, existing bow handles are divided into left-hand and right-hand handles, each corresponding to a different holding method, resulting in poor versatility. In this invention, by setting different numbers of shims 4 between the front and rear sides of the bow handle post 1 and the movable block 2, the movable block 2 is offset forward or backward relative to the bow handle post 1. The amount of offset of the movable block 2 is controlled by adjusting the number of shims 4, thus making this invention applicable to both left-hand and right-hand holding methods, improving its versatility.
[0040] See Figure 1 , Figure 2 The right side of the movable block 2 is fixed with a socket 5 by bolts. The socket 5 is provided with a slot 51 for the insertion of the bow piece. The right side of the movable block 2 is provided with a fixing bolt 52 for fixing the bow piece.
[0041] By fitting the bow piece into the slot 51 and then snapping it onto the fixing bolt 52, the socket 5 facilitates the installation of the bow piece, and the stability of the bow piece is improved by using the socket 5 and the fixing bolt 52.
[0042] See Figures 1-3The movable block 2 has a first screw hole 29, and the socket 5 has a countersunk hole 53 aligned with the first screw hole 29. The front and rear sides of the movable block 2 are provided with second screw holes 30 for adjusting the front and rear offset angle of the socket 5. The second screw holes 30 are located on the front and rear sides of the socket 5.
[0043] The socket 5 and the movable block 2 are fixed together by countersunk screws. The head of the countersunk screw is located within the countersunk hole 53 to prevent the screw head from protruding and affecting the installation of the bow piece. By screwing screws into the two second screw holes 30 at the front and rear of the socket 5, the inner end of the screw abuts against the front and rear sides of the socket 5, thereby precisely adjusting and fixing the front and rear offset angle of the socket 5, and preventing the bow piece from being misaligned when fixed to the socket 5, which would affect the accuracy of the bow.
[0044] See Figure 1 , Figure 2 The left side of the movable block 2 is set as an inclined surface 31.
[0045] The left side of the movable block 2 is inclined 31. The weight of the movable block 2 is reduced by reducing the thickness of the front and rear sides of the movable block 2 except for the socket part 5, thereby reducing the weight of the bow and improving the bow's operability.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
