Description

Technical Field

[0001] The utility model relates to the technical field of sights used for bows and arrows, in particular to a fine-tuning sight used for bows and arrows. Background Art

[0002] The bow and arrow is a well-known tool, widely used in fitness, athletics, hunting, and combat. A typical bow and arrow consists of a bow with a string and an arrow. To use it, the tail end of the arrow rests on the string. While holding the bow with one hand, the other hand pulls back the string and the arrow. At the same time, aim the arrow at the target and quickly release the string. The rebound force of the string causes the arrow to shoot quickly toward the target, completing the shooting action.

[0003] Since traditional bows and arrows have no auxiliary aiming devices and can only be aimed directly by the naked eye, the accuracy of the arrows shot depends on the user's experience and judgment. For novices, it is difficult to guarantee a hit rate.

[0004] In addition, bows and arrows designed to improve shooting accuracy have also appeared on the market. These bows consist of a bow body and an arrow, with a sight mounted in the middle of the bow body. The sight includes a sight window with a sight inside. The user observes the sight's target point, which appears in the distance, and then releases the arrow, significantly improving accuracy.

[0005] However, the existing sights are fixed relative to the bow body, or are relatively complicated and difficult to adjust, and different users may have different usage habits. In addition, the sights also need to be adjusted accordingly for targets at different distances.

[0006] Therefore, how to provide a fine-tuning sight for a bow and arrow that can be installed on the bow and arrow, and can perform subtle fine-tuning on the sight and rapid and large-scale adjustment on it, is a technical problem that needs to be solved. Utility Model Content

DETAILED DESCRIPTION

[0040] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figures 1 to 11 In an embodiment of the utility model, a fine-tuning sight for a bow and arrow includes a mounting bracket 10, a vertical movement mechanism 20, a horizontal movement mechanism 90 and a front sight rod 11. The mounting bracket 10 is used to mount the sight on an external bow and arrow. The fixed end of the vertical movement mechanism 20 is fixedly connected to the mounting bracket 10, and its movable end is fixedly connected to the fixed end of the horizontal movement mechanism 90. The movable end of the horizontal movement mechanism 90 forms a transmission connection with the front sight rod 11, so that the horizontal movement mechanism 90 can drive the front sight rod 11 to move a certain distance in the horizontal direction, and the vertical movement mechanism 20 can drive the horizontal movement mechanism 90 and the front sight rod 11 to move a certain distance synchronously in the vertical direction, thereby adjusting the accuracy of the front sight of the front sight rod 11.

[0042] Specifically, in order to improve the accuracy of bow and arrow shooting and thus increase the user's hit rate on the target, it is preferable to set a corresponding sight on the bow and arrow to aim at the target and shoot. In addition, due to the different distances of the target, different bow and arrow parameters, and different user usage habits, in order to improve the hit rate, it is preferable to adjust the sight and optimize it according to different conditions.

[0043] However, the existing sights are fixed relative to the bow body, or are relatively complicated and difficult to adjust, and different users may have different usage habits. In addition, the sights also need to be adjusted accordingly for targets at different distances.

[0044] Therefore, by providing the fine-tuning sight with corresponding vertical movement mechanisms 20 and horizontal movement mechanisms 90, the sight's front sight rod 11 can be moved vertically or horizontally, thereby allowing the sight to be adjusted as needed. In particular, corresponding fast-moving devices and fine-adjusting devices are also provided on the vertical movement mechanisms 20 and horizontal movement mechanisms 90. When installed on a bow and arrow, the sight can be fine-tuned and quickly adjusted over a wide range, thus optimizing the user experience and allowing the sight rod 11 to be adjusted to the appropriate position, thereby improving the accuracy of the sight and increasing the accuracy of the bow and arrow shooting.

[0045] In order to indicate or mark the vertical adjustment distance of the sight rod 11, a vertical scale 31 is preferably provided on the scale frame 30, and a vertical pointer 23 is fixed on the vertical sliding seat 21. In addition, in order to better observe the sight on the sight rod 11 and facilitate the aiming operation, a corresponding sight window 13 can also be provided at the sight position of the sight rod 11.

[0046] like Figures 2 to 4 As shown, preferably, the vertical movement mechanism 20 is provided with a scale frame 30, a fine-tuning screw 40, a passive shaft 50 and a vertical movement slide 21, one side of the scale frame 30 is fixed to the mounting bracket 10, and the other side thereof is provided with a vertical movement slide 32, the vertical movement slide 21 is slidably connected to the vertical movement slide 32, and can move a certain distance along the vertical movement slide 32; the fine-tuning screw 40 is rotatably connected to the scale frame 30, the passive shaft 50 is installed on the vertical movement slide 21, and is sleeved on the fine-tuning screw 40 to form a transmission connection, so that the fine-tuning screw 40 rotates, which can drive the passive shaft 50 to move along the axial direction of the fine-tuning screw 40, thereby driving the vertical movement slide 21 to move vertically along the scale frame 30.

[0047] Specifically, in order to make the connection between the vertical slide 21 and the vertical slide rail 32 tighter, a steel rubber part can be set between the vertical slide 21 and the vertical slide rail 32, and the good sliding performance and wear resistance of the steel rubber part can be utilized to enable the vertical slide 21 to move smoothly on the vertical slide rail 32 without scratching the surface.

[0048] Secondly, in order to facilitate assembly, the vertical slide 21 can be set as two separable parts, each of which can be provided with a V-shaped groove, and the V-shaped slide rails of the vertical slide rail 32 can be clamped from both sides of the vertical slide rail 32, and the two parts can be fixedly connected by bolts so that they fit tightly on the vertical slide rail 32 to form a stable sliding connection.

[0049] Again, in order to rotate the fine-tuning screw 40, a vertical shift knob 41 is preferably mounted on one end thereof. The vertical shift knob 41 is fixedly connected to the fine-tuning screw 40 and can rotate the fine-tuning screw 40. In order to improve the stability of the vertical shift knob 41 after rotation, a clamping device (not shown in the figure) can be provided between the vertical shift knob 41 and the scale center frame 30. For example, a clamping spring, a clamping ball, and a clamping groove can be provided. The elastic force of the clamping spring can be used to press the clamping ball into the clamping groove. This means that when the vertical shift knob 41 is rotated, a relatively large rotational force is required to overcome the elastic force of the clamping spring before it can be rotated and adjusted.

[0050] like Figures 4 to 6 As shown, preferably, the passive shaft 50 is provided with a first through hole 51 along the axial direction of the fine-tuning screw 40, one side of the first through hole 51 is provided with a fan-shaped thread 52, and the other side thereof is provided with a smooth side wall, and the passive shaft 50 is sleeved on the fine-tuning screw 40 through the first through hole 51, and the fan-shaped thread 52 forms a threaded connection with the fine-tuning screw 40.

[0051] Specifically, to enable the rotating fine-tuning screw 40 to drive the passive shaft 50, a first through hole 51 can be provided on the passive shaft 50, and a threaded protrusion can be provided on the inner wall of the first through hole 51 to form a threaded connection with the outer thread of the fine-tuning screw 40. To allow the passive shaft 50 to be separated from the fine-tuning screw 40 by a certain distance, thereby allowing for rapid movement along the axial direction of the fine-tuning screw 40, it is preferred that the diameter of the first through hole 51 be set larger than the diameter of the fine-tuning screw 40, and the inner wall of the first through hole 51 on the other side opposite the fan-shaped thread 52 be set as a smooth sidewall. This allows the passive shaft 50, after being driven by the quick-shift button 70 and separated from the fine-tuning screw 40, to rapidly move along the fine-tuning screw 40, thereby rapidly adjusting the vertical sight of the sight.

[0052] Secondly, if Figure 6As shown, the quick-shift button 70 presses the passive shaft 50 to form a quick-shift state, that is, the passive shaft 50 is pressed into the auxiliary shaft seat 60 a certain distance under the pressing and driving of the quick-shift button 70, so that the fan-shaped thread 52 is separated from the external thread of the fine-tuning screw 40, that is, the fine-tuning screw 40 is slidably connected to one side of the smooth side wall, thereby releasing the locking relationship between the passive shaft 50 and the fine-tuning screw 40, so that the vertical movement mechanism 20 can be quickly and widely adjusted relative to the scale center frame 30, thereby achieving the effect of quick adjustment of the sight.

[0053] like Figure 4 、 Figure 6 and Figure 7 As shown, preferably, the vertical movement mechanism 20 is further provided with an auxiliary shaft seat 60 and a pre-tightening spring 63. The auxiliary shaft seat 60 is fixedly connected to the vertical movement slide 21. The auxiliary shaft seat 60 is provided with a first countersunk hole 61 along the axial direction of the passive shaft rod 50. The passive shaft rod 50 is penetrated through the first countersunk hole 61 and can move a certain distance along the inner wall of the first countersunk hole 61; the auxiliary shaft seat 60 is provided with a second through hole 62 corresponding to the position of the first through hole 51 of the passive shaft rod 50, and the fine-tuning screw 40 is penetrated through the second through hole 62 and can move freely along the second through hole 62; one end of the pre-tightening spring 63 abuts against the auxiliary shaft seat 60, and the other end thereof abuts against one end of the fan-shaped thread 52 set on the passive shaft rod 50. The elastic force of the pre-tightening spring 63 drives the fan-shaped thread 52 to fit tightly with the fine-tuning screw 40 to form a threaded transmission connection.

[0054] Specifically, in order to make the fine-tuning screw 40 rotate, it can better drive the passive shaft 50 to move along the scale frame 30 for fine-tuning, so an auxiliary shaft seat 60 and a pre-tightening spring 63 can be provided, so that the passive shaft 50 can be inserted into the auxiliary shaft seat 60, and then the elastic force of the pre-tightening spring 63 can make the fan-shaped thread 52 of the passive shaft 50 press against the fine-tuning screw 40, so as to achieve a close fit and enhance the effect of its thread transmission. Figure 3 As shown, the fan-shaped thread 52 of the passive shaft 50 and the external thread of the fine-tuning screw 40 form a tightly fitting thread transmission state, so that by rotating the fine-tuning screw 40, the passive shaft 50 and the vertical movement mechanism 20 can be finely adjusted.

[0055] In addition, preferably, the auxiliary shaft seat 60 and the passive shaft rod 50 can be set to maintain a concentric state to ensure that the passive shaft rod 50 can slide smoothly inside the first countersunk hole 61 of the auxiliary shaft seat 60.

[0056] like Figures 5 to 7As shown, preferably, the vertical movement mechanism 20 is further provided with a quick-moving button 70, which is movably connected to one end of the passive shaft 50 away from the preload spring 63, and can press the passive shaft 50 to move it a certain distance toward one end of the fan-shaped thread 52, thereby releasing the threaded connection between the fan-shaped thread 52 and the fine-tuning screw 40, and thus allowing the vertical movement mechanism 20 to move quickly along the scale frame 30.

[0057] Specifically, to install the quick-shift button 70, a U-shaped groove 54 may be formed at one end of the passive shaft 50, so that the quick-shift button 70 can be movably connected to the U-shaped groove 54. It is understood that, to avoid the quick-shift button 70, a similar opening may be provided at the position of the auxiliary shaft seat 60 corresponding to the U-shaped groove 54, so that the active inclined surface 72 of the quick-shift button 70 can move toward the positioning hole 53, thereby unlocking the locking rod 82.

[0058] Furthermore, to make the pressing stroke of the quick-shift button 70 smoother, a guide block 55 is preferably provided on the passive shaft 50, and an elongated guide slot 71 is provided at the position of the quick-shift button 70 corresponding to the guide block 55. The two ends of the guide block 55 are respectively fixed to the passive shaft 50 and pass through the elongated guide slot 71 to form a sliding connection. Furthermore, the guide block 55 can also limit the quick-shift button 70, preventing it from escaping from the U-shaped slot 54.

[0059] Secondly, when the sight needs to be adjusted quickly, the fine-tuning threaded connection between the passive shaft 50 and the fine-tuning screw 40 can be separated, that is, the quick-shift button 70 can be used to press the passive shaft 50 in the direction of the fan-shaped thread 52 for a certain distance, so that the threaded connections formed by them can be disengaged from each other. Then, the diameter of the first through hole 51 can be used to be larger than the diameter of the fine-tuning screw 40, so that the passive shaft 50 does not contact the fine-tuning screw 40, and can be quickly moved in the axial direction of the fine-tuning screw 40. Similarly, the diameter of the second through hole 62 of the auxiliary shaft seat 60 is also larger than the diameter of the fine-tuning screw 40, so it can also be quickly moved, thereby quickly moving the entire vertical movement mechanism 20.

[0060] like Figures 4 to 7 As shown, preferably, the vertical movement mechanism 20 is further provided with a locking seat 80, a locking rod 82 and a locking spring 84, the locking seat 80 is fixed to the vertical movement slide 21, the locking rod 82 is slidably connected to the vertical movement slide 21, one end of the locking spring 84 abuts against the locking seat 80, and the other end thereof abuts against the locking rod 82, and the locking rod 82 can perform a locking operation on the passive shaft rod 50; the passive shaft rod 50 is provided with a positioning hole 53 at a position corresponding to the locking rod 82, and the locking rod 82 can be embedded in the positioning hole 53 to form a locking positioning operation.

[0061] Specifically, since the passive shaft 50 is under the elastic force of the preloaded spring 63, a corresponding threaded transmission connection is generated between the sector thread 52 and the external thread of the fine-tuning screw 40. However, due to the deformation characteristics of the spring, during the movement or shooting of the bow and arrow, the spring may be uncontrollably squeezed due to shaking or trembling, thereby causing a certain gap to appear between the sector thread 52 and the fine-tuning screw 40 in a tightly fitted state, thereby causing the position of the passive shaft 50 relative to the fine-tuning screw 40 to change, causing the position of the sight relative to the scale center frame 30 to change, affecting the position of the sight's front sight, and possibly affecting the hit rate of the bow and arrow.

[0062] Therefore, a corresponding locking device can be provided to lock the position of the passive shaft 50 so that it can maintain a constant and tight fit with the fine-tuning screw 40 even during shaking or trembling. Specifically, the locking rod 82 can extend into the positioning hole 53 to a certain length under the elastic force of the locking spring 84, thereby locking and positioning the passive shaft 50, preventing the passive shaft 50 from being pressed and moved, and maintaining a constant and tight fit between the fan-shaped thread 52 of the passive shaft 50 and the fine-tuning screw 40, thereby firmly fixing the vertical movement mechanism 20 to the fine-tuning screw 40 and the scale frame 30.

[0063] Secondly, the locking seat 80 is further provided with a limit bar 81 at a position corresponding to the quick-moving button 70 . The limit bar 81 can limit the quick-moving button 70 to prevent the quick-moving button 70 from escaping from the U-shaped groove 54 .

[0064] like Figure 5 and Figure 7 As shown, preferably, the locking rod 82 is provided with an unlocking slope 83 on the side facing the quick shift button 70, and the quick shift button 70 is provided with an active slope 72 at one end corresponding to the unlocking slope 83. The active slope 72 cooperates with the unlocking slope 83 so that the quick shift button 70 can drive the locking rod 82 to move away from the positioning hole 53, thereby releasing the locking positioning operation of the passive shaft 50.

[0065] Specifically, when the quick-shift button 70 is pressed in the direction of the fan-shaped thread 52 of the passive shaft rod 50, the active inclined surface 72 of the quick-shift button 70 first contacts the unlocking inclined surface 83 of the locking rod 82. As the quick-shift button 70 is continuously pressed, a driving force along the axial direction of the locking rod 82 can be formed on the unlocking inclined surface 83, so that the locking rod 82 moves a certain distance away from the positioning hole 53, thereby releasing the limiting effect on the positioning hole 53, that is, releasing the locking and positioning operation of the passive shaft rod 50, so that the quick-shift button 70 can continue to be pressed, applying a certain pressing force to the passive shaft rod 50, so that the fan-shaped thread 52 of the passive shaft rod 50 moves a certain distance away from the fine-tuning screw 40, thereby releasing the threaded connection between the fan-shaped thread 52 and the passive shaft rod 50, so that the vertical movement mechanism 20 can move quickly along the scale middle frame 30.

[0066] Next, after the vertical movement mechanism 20 has been quickly moved to the desired position, the quick-movement button 70 can be released, thereby releasing the pressing and pushing driving force on the passive shaft 50 and the locking rod 82. Consequently, the passive shaft 50 is moved in the opposite direction by a certain distance under the elastic force of the preload spring 63, thereby re-threading the fan-shaped thread 52 into a threaded connection with the fine-tuning screw 40. Simultaneously, the locking rod 82 is also moved in the opposite direction by a certain distance under the elastic force of the locking spring 84, and is re-engaged in the positioning hole 53 of the passive shaft 50, thereby achieving the locking and positioning operation of the passive shaft 50.

[0067] Again, in order to make the locking positioning of the passive shaft 50 more balanced and stable, it is preferred to set two positioning holes 53 on both sides of the passive shaft 50 along the axial direction of the fine-tuning screw 40. Similarly, two sets of locking seats 80, locking rods 82 and locking springs 84 are also set accordingly, so as to perform locking and positioning operations on the passive shaft 50 in two directions.

[0068] like Figure 7 、 Figure 8 and Figure 11 As shown, preferably, the transverse movement mechanism 90 is provided with a dovetail seat 91, a transverse movement knob 94 and a locking wrench 95, the vertical movement slide 21 is provided with a dovetail groove 22, the dovetail seat 91 is detachably fixedly connected to the vertical movement slide 21 through the dovetail groove 22, the locking wrench 95 forms a rotating shaft connection with the vertical movement slide 21, and performs a locking operation on the dovetail seat 91; the front sight rod 11 is movably connected to the dovetail seat 91, one end of the transverse movement knob 94 is rotatably connected to the dovetail seat 91, and the other end thereof is transmission-connected to the front sight rod 11.

[0069] Specifically, the coordinated arrangement of the dovetail seat 91 and the dovetail groove 22 allows the transverse movement mechanism 90 to be quickly assembled on the vertical movement mechanism 20, or the transverse movement mechanism 90 to be quickly moved laterally. Simply by turning the locking wrench 95 and releasing the locking operation on the dovetail seat 91, the transverse movement mechanism 90 can be quickly moved. In order to fine-tune the alignment rod 11 laterally, a transverse movement knob 94 can be provided, and a portion of the alignment rod 11 is provided with a corresponding external thread structure, while the corresponding portion of the transverse movement knob 94 is provided with an internal thread structure. Utilizing the coordinated transmission effect between the internal and external threads, the rotation of the transverse movement knob 94 can drive the alignment rod 11 to move laterally relative to the dovetail seat 91, thereby fine-tuning the front sight of the alignment rod 11 laterally.

[0070] like Figure 9 and Figure 10 As shown, preferably, the dovetail seat 91 is provided with a third through hole 92 , and the cross section of the third through hole 92 is set to a D-shaped cross section, and the cross section of the sight rod 11 is set to a D-shaped cross section, so that the sight rod 11 can slide axially along the third through hole 92 .

[0071] Specifically, in order to prevent the sight rod 11 from performing its own circumferential rotation in the third through hole 92 of the dovetail seat 91 and preventing the positional relationship between the sight rod 11 and the dovetail seat 91 from being adjusted, the third through hole 92 can be set to a D-shaped cross-section, and the sight rod 11 can also be set to a D-shaped cross-section, thereby ensuring that the sight rod 11 can only slide along the axial direction of the third through hole 92 and cannot perform circumferential rotation inside the third through hole 92.

[0072] like Figures 9 to 11 As shown, preferably, the transverse movement mechanism 90 is further provided with a clamping block 96 and a clamping bolt 97, the dovetail seat 91 is provided with a fourth through hole 93, and the cross section of the fourth through hole 93 is set to a D-shaped cross section, the cross section of the clamping block 96 is set to a D-shaped cross section, the clamping block 96 is passed through the fourth through hole 93, so that the plane side of the clamping block 96 abuts against the plane side of the front sight rod 11, the clamping bolt 97 is threadedly connected to the dovetail seat 91, and abuts against the side of the clamping block 96 away from the front sight rod 11, so that the clamping block 96 can perform a clamping operation on the front sight rod 11.

[0073] Specifically, in order to prevent the sight rod 11 from rotating in the third through hole 92, it is preferred to abut the planar side of the pressing block 96 against the planar side of the sight rod 11, where the planar side is the other side relative to the arc side of the D-shaped cross-section and has a planar structure, thereby preventing rotation.

[0074] Secondly, in order to ensure that the front sight rod 11 can be stably mounted on the dovetail seat 91, it is preferably provided with a clamping block 96 and a clamping bolt 97 for clamping it. In order to allow the front sight rod 11 to move on the dovetail seat 91, it is preferably provided with a material having certain sliding properties, such as a material such as a steel rubber. When the clamping block 96 clamps the front sight rod 11, the front sight rod 11 can also be fine-tuned by a certain distance under the drive of the traverse knob 94.

[0075] It is understood that the abutting block 96 and the abutting bolt 97 can also limit or lock the lateral movement of the sight rod 11. That is, the friction of the sight rod 11 relative to the dovetail seat 91 can be adjusted by adjusting the tightness of the abutting bolt 97. In other words, when the abutting bolt 97 is relatively loose, the friction of the sight rod 11 relative to the dovetail seat 91 is small, the movement is easier, and the lateral movement knob 94 can be quickly rotated to perform relatively fast fine-tuning of the sight rod 11.

[0076] When the tightening bolt 97 is relatively tight, the friction between the front sight rod 11 and the dovetail seat 91 is relatively large, and the movement is difficult. The only way to perform relatively slow fine-tuning operations on the front sight rod 11 is to rotate the lateral knob 94 relatively slowly.

[0077] In addition, in order to indicate or mark the lateral adjustment distance of the sight rod 11 , it is preferred to provide a lateral scale on the dovetail seat 91 and fix a lateral pointer 12 on the sight rod 11 .

[0078] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
