DETAILED DESCRIPTION

[0035] The technical scheme in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0036] Please refer to Figures 1 to 11The utility model discloses an independent adjustable fine adjustment mechanism, including the adjusting frame 10, passive adjustment piece 20, foresight component 40 and active adjustment piece 30, passive adjustment piece 20 is fixedly connected in the adjusting frame 10, foresight component 40 swing joint is in the adjusting frame 10, active adjustment piece 30 is installed in foresight component 40, and with passive adjustment piece 20 forms transmission connection, thereby with active adjustment piece 30 can along passive adjustment piece 20 moves certain distance, and then with active adjustment piece 30 drives foresight component 40 and moves along the adjusting frame 10 synchronously.

[0037] Specifically, in the competition or outdoor environment, in order to promote the adjustment flexibility and precision of the gunsight, the fine adjustment mechanism can be provided on the gunsight, the interactive mechanics design of passive adjustment piece 20 and active adjustment piece 30 can realize more accurate and convenient aiming adjustment.

[0038] Secondly, active adjustment piece 30 can be provided as adjusting gear 31, and passive adjustment piece 20 can be provided as adjusting rack 21, the meshing design between adjusting rack 21 and adjusting gear 31 not only improves the stability of adjustment, but also enhances the intuitiveness and convenience of user operation. Through the design of the fine adjustment mechanism, the user no longer needs to frequently adjust the entire gunsight when aiming, but can realize accurate fine adjustment of each group of sighting pins 41 through simple rotation operation, greatly improving the practicability and use experience.

[0039] Thirdly, passive adjustment piece 20 can also be provided as a transmission belt, and active adjustment piece 30 can also be provided as a transmission pulley, the transmission connection between the transmission belt and the transmission pulley can also make the transmission pulley drive the sighting pins 41 to move along the transmission belt by rotating the transmission pulley. Alternatively, passive adjustment piece 20 can also be provided as a transmission chain, and active adjustment piece 30 can also be provided as a transmission sprocket, the transmission connection between the transmission chain and the transmission sprocket can also make the transmission sprocket drive the sighting pins 41 to move along the transmission chain by rotating the transmission sprocket. It can be understood that passive adjustment piece 20 and active adjustment piece 30 can also adopt other transmission connection structures, as long as they can drive active adjustment piece 30 to move along passive adjustment piece 20, which will not be described here.

[0040] For example, Figures 1 to 6As shown, preferably, the foresight assembly 40 is provided with a foresight needle 41, one end of the foresight needle 41 is formed with a foresight 43, and the other end is slidingly connected to the adjusting frame 10; the passive adjusting member 20 is provided with an adjusting rack 21, and the adjusting rack 21 is fixedly connected to the adjusting frame 10; the active adjusting member 30 is provided with an adjusting gear 31 and a cap pin shaft 32 which are fixedly connected to each other, and the adjusting gear 31 is installed on the end of the foresight needle 41 slidingly connected to the adjusting frame 10 through the cap pin shaft 32, and is in meshing connection with the adjusting rack 21 to form a transmission connection.

[0041] Specifically, the user can rotate the cap pin shaft 32 to drive the adjusting gear 31 to rotate synchronously, and through the meshing connection, the adjusting gear 31 can move along the adjusting rack 21 by the same distance. Further, the foresight needle 41 can also move along the adjusting frame 10 by a certain distance synchronously, so as to realize the independent adjustment of the foresight needle 41.

[0042] Secondly, the adjusting gear 31 can be sleeved on the shaft rod of the cap pin shaft 32 and form an interference fit, so as to be fixedly connected to the cap pin shaft 32, so that the cap pin shaft 32 can drive the adjusting gear 31 to rotate synchronously.

[0043] As shown in Figure 4 and Figure 6 , preferably, the end of the foresight needle 41 installed with the cap pin shaft 32 is provided with a first pin hole 44, and the end of the cap pin shaft 32 is penetratingly arranged in the first pin hole 44 to form a rotating connection, and the other end is provided with a driving head 33 for applying a rotating torque.

[0044] Specifically, the cap pin shaft 32 can be provided in the shape of a cylindrical head hexagonal screw without a threaded structure, and the screw rod part is not threaded, so it can rotate freely in the first pin hole 44. And the head can be provided with an internal hexagonal groove, which is convenient for applying a rotating torque to make it rotate, so as to drive the adjusting gear 31 to rotate synchronously, and realize the adjustment operation of the foresight needle 41.

[0045] In another embodiment, as shown in Figure 6 , preferably, the foresight needle 41 is also provided with a positioning pin 45, and the end of the cap pin shaft 32 penetratingly arranged in the first pin hole 44 is provided with a positioning groove 34, and the positioning pin 45 and the positioning groove 34 are matched with each other to limit the cap pin shaft 32.

[0046] Specifically, the positioning pin 45 can be fixed to a suitable position of the side wall of the first pin hole 44 through a corresponding positioning through hole, so that a part of the circumferential side wall of the positioning pin 45 can be embedded into the positioning groove 34, thereby forming a certain embedded connection, so that the positioning pin 45 can form a limiting action on the capped pin shaft 32 to prevent the capped pin shaft 32 from being pulled out of the first pin hole 44. It can be understood that the positioning pin 45 only limits the axial direction of the capped pin shaft 32, and does not form a limiting action in the circumferential direction, that is, even if the positioning groove 34 of the capped pin shaft 32 forms an embedded connection with the positioning pin 45, the capped pin shaft 32 can still rotate in the circumferential direction of the capped pin shaft 32.

[0047] As shown in Figures 3 to 5 Preferably, the adjusting frame 10 is provided with a fixed part 11, the sighting pin 41 is provided with a sliding part 42, and the sliding part 42 and the fixed part 11 are matched with each other to form a sliding connection.

[0048] Specifically, since the sighting pin 41 needs to move under the cooperation of the adjusting frame 10 to realize the adjustment of the position, a corresponding combination of the fixed part 11 and the sliding part 42 needs to be provided to form a sliding connection, so that it is convenient to adjust. In order to further stably support the sighting pin 41, it is preferred that the sliding part 42 is arranged on both sides of the sighting pin 41, and the fixed part 11 is arranged on the adjusting frame 10 corresponding to the positions of both sides of the sighting pin 41, so that the adjusting frame 10 can form a relatively uniform supporting force on the sighting pin 41 from both sides of the sighting pin 41.

[0049] Secondly, the adjusting frame 10 can also be provided with a U-shaped support, so that the fixed part 11 can be arranged on the two supporting arms of the U-shaped support to form a clamping structure for the sighting pin 41, and further stably support it. The fixed part 11 can be arranged as a concave sliding groove, and the sliding part 42 can be arranged as a convex sliding block, so that the concave sliding groove and the convex sliding block are embedded with each other and form a sliding connection. Alternatively, the fixed part 11 can be arranged as a convex sliding rail, and the sliding part 42 can be arranged as a concave sliding block, so that the convex sliding rail and the concave sliding block are clamped with each other and form a corresponding sliding connection.

[0050] As shown in Figure 3 and Figure 5 Preferably, a damping part 12 is arranged between the adjusting frame 10 and the sighting pin 41, one side of the damping part 12 is fixed to the adjusting frame 10, and the other side of the damping part 12 is in sliding connection with the sighting pin 41.

[0051] Specifically, if the aiming needle 41 is only supported by the sliding connection between the fixed part 11 and the sliding part 42, the aiming needle 41 is prone to instability. Therefore, a corresponding damping part 12 can be arranged between the aiming needle 41 and the adjusting rack 10. By using the elasticity and damping effect of the damping part 12, a certain frictional resistance can be applied to the movement of the aiming needle 41, thereby further enhancing the stability of the aiming needle 41 connected to the adjusting rack 10.

[0052] Secondly, the damping part 12 can be made of a material with certain deformation ability and elasticity, such as plastic material. The size of the damping part 12 can be slightly larger than the gap between the adjusting rack 10 and the aiming needle 41, so that when the damping part 12 is installed between the adjusting rack 10 and the aiming needle 41, it can be squeezed to produce a certain deformation, thereby generating a certain resistance to the aiming needle 41, preventing the free movement of the aiming needle 41 in the non-adjusting state and improving its stability.

[0053] Thirdly, the damping part 12 can be provided in a sheet shape, one side of which is attached and fixed to the adjusting rack 10, and the other side is abutted by the side wall of the aiming needle 41, and the aiming needle 41 can slide along the sheet-shaped damping part 12 when a certain external force is applied to drive it. Alternatively, the damping part 12 can be provided in a column shape, and two semicircular grooves are respectively arranged at positions corresponding to the adjusting rack 10 and the aiming needle 41, so that the column-shaped damping part 12 can be fixed to the semicircular groove of the adjusting rack 10, and the semicircular groove of the aiming needle 41 can be slidingly connected to the column-shaped damping part 12, so that the aiming needle 41 can slide along the column-shaped damping part 12 when a certain external force is applied to drive it.

[0054] As shown in Figures 1 to 3 Preferably, the adjusting rack 10 is provided with a mountain-shaped support, and two groups of fixed parts 11 are respectively formed between the three support arms of the mountain-shaped support. The passive adjusting part 20 is provided with two groups of adjusting racks 21 at positions corresponding to the two groups of fixed parts 11.

[0055] Specifically, so that multiple aiming assembly groups 40 can be slidingly connected to the two groups of fixed parts 11 and form meshing connection with the two groups of adjusting racks 21. For example, between the three support arms, a first group of sliding grooves 13 and a second group of sliding grooves 14 can be formed, a first group of racks 22 is formed at the position of the first group of sliding grooves 13, and a second group of racks 23 is formed at the position of the second group of sliding grooves 14. The aiming assembly 40 can be installed in the first group of sliding grooves 13 and form transmission connection with the first group of racks 22. It can also be installed in the second group of sliding grooves 14 and form transmission connection with the second group of racks 23.

[0056] Second, for the bow sight, usually set a plurality of different sighting distance sight 41, such as can be set five groups of sight 41. Although in the slide groove group 13 and rack group 22 formed by the fine adjustment mechanism group, also can install a plurality of sight 41, but five groups are installed in the same group of fine adjustment mechanism, relatively crowded, its adjustment distance is limited, not convenient for actual use.

[0057] Preferably, two groups of fine adjustment mechanism can be set on the adjustment frame 10, the three arms of the adjustment frame 10 can form a slide groove group 13 and a slide groove group 14, and the two sides of the component where the adjustment rack 21 is located can form a rack group 22 and a rack group 23, so as to cooperate with each other to form two groups of fine adjustment mechanism, which is convenient for setting a plurality of sight 41. For example, two groups of sight 41 can be installed in the first fine adjustment mechanism, and three groups of sight 41 can be installed in the second fine adjustment mechanism, and the sight 41 installed in the first fine adjustment mechanism and the sight 41 installed in the second fine adjustment mechanism are spaced apart from each other, so as to facilitate independent adjustment of the sight 41, and the user can adjust the position relationship of the plurality of sight 41 relative to the adjustment frame 10 according to the sighting distance, to form a more accurate sighting system and improve the shooting accuracy in multiple distances.

[0058] As shown in Figure 1 and Figure 11 Preferably, the utility model also provides a sight, which comprises a sighting seat 50 and a sighting frame 60 which are fixed to each other, and the fine adjustment mechanism is installed in the sighting seat 50, one end of the foresight assembly 40 extends into the sighting frame 60 by a certain length to form a corresponding foresight 43.

[0059] Specifically, on the side of the sighting seat 50 where the cap pin 32 of the fine adjustment mechanism is installed, an adjustment cover 52 can also be fixed, the adjustment cover 52 covers the outside of the adjustment rack 21 of the fine adjustment mechanism to protect the adjustment rack 21 and the adjustment gear 31. A corresponding scale can also be provided on the adjustment cover 52, so that the user can adjust the cap pin 32 by referring to the scale, thereby improving the adjustment accuracy of the sight 41. It can be understood that the position corresponding to the movement track of the cap pin 32 needs to be provided with a corresponding long strip-shaped opening, so that the cap pin 32 can be conveniently adjusted from the outside.

[0060] Secondly, an auxiliary adjusting tool can also be provided to assist in rotating the capped pin shaft 32, so that the user can easily adjust the sighting pin 41. For example, an adjusting bolt 53 can be provided, one end of which is provided with an adjusting handle 54, and the other end is provided with an internal hexagonal wrench 55, which is used to cooperate with the internal hexagonal groove of the driving head 33 of the capped pin shaft 32, so that the user can easily twist the capped pin shaft 32 to produce rotation, and then independently adjust the sighting pin 41. It can be understood that when the driving head 33 of the capped pin shaft 32 is provided with other different shaped grooves, the end of the internal hexagonal wrench 55 of the adjusting bolt 53 can also be provided with a corresponding other shaped wrench, so that it can twist the driving head 33 of the capped pin shaft 32.

[0061] Thirdly, in order to facilitate the storage of the adjusting bolt 53, a corresponding storage hole 56 can also be provided on the sighting frame 60 or the vertical slider 76, a corresponding internal thread is provided on the inner side wall of the storage hole 56, and a corresponding external thread is provided at the middle position of the adjusting bolt 53, so that it can be screwed into the storage hole 56 to be fixed therein. In use, the adjusting bolt 53 is rotated in the opposite direction to be screwed out of the storage hole 56, and the internal hexagonal wrench 55 at one end is used to rotate and adjust the capped pin shaft 32. After adjustment is completed, it can be screwed into the storage hole 56 again, and can be stored again.

[0062] As shown in Figure 7 , Figure 8 and Figure 10 , preferably, it also includes a light beam 62 installed at the frame of the sighting frame 60 for emitting light.

[0063] Specifically, in order to improve the convenience of using the sight in the night or low light environment, a light beam 62 can also be installed at the annular frame of the sighting frame 60, and it can be energized to emit light to illuminate the sighting frame 60. The battery for energizing it can be provided on the sighting seat 50, or on the external bow body, and can be connected in use.

[0064] Secondly, a corresponding light beam 62 or light guide fiber can also be provided at the foresight position of the foresight 41 of the foresight assembly 40, so that the foresight position can also emit a certain brightness, which is convenient for use in the night or low light environment.

[0065] In addition, in order to facilitate the installation of the light-emitting bundle 62, a ring-shaped cover body 61 can also be arranged at the frame body of the aiming frame 60, so that the light-emitting bundle 62 can be directly installed inside the ring-shaped cover body 61, and the ring-shaped cover body 61 is arranged in a light-transmitting structure, so that the light of the light-emitting bundle 62 can pass through the ring-shaped cover body 61 and be emitted as light, forming a light-emitting and bright state, facilitating observation and use. The ring-shaped cover body 61 can be fixed on the aiming frame 60 in a buckle connection or bolt connection manner.

[0066] As shown in Figures 7 to 10 Preferably, a vertical moving mechanism 70 is further included, the aiming seat 50 is provided with a vertical sliding rail 51, the vertical moving mechanism 70 is provided with a vertical screw rod 71, a vertical nut column 73, a vertical sliding block 76 and a vertical handle 75, the vertical screw rod 71 is rotationally connected to the vertical sliding rail 51, and the vertical nut column 73 is threadedly connected to the vertical screw rod 71 through a screw hole; one end of the vertical nut column 73 is provided with a vertical limiting plate 74, and the other end is threadedly connected to the vertical handle 75; the vertical sliding block 76 is sleeved on the vertical nut column 73 and abuts against both sides of the vertical sliding rail 51, respectively.

[0067] Specifically, one end of the vertical screw rod 71 is provided with a vertical knob 72, the vertical knob 72 is fixedly connected to the vertical screw rod 71 and used for rotating operation of the vertical screw rod 71. The vertical nut column 73 is provided with a screw hole corresponding to the position of the vertical screw rod 71, the inner wall of the screw hole is provided with an internal thread, the outer wall of the vertical screw rod 71 is provided with an external thread, and the internal thread and the external thread are matched with each other to form a corresponding threaded transmission connection. Although the vertical sliding block 76 and the vertical limiting plate 74 abut against both sides of the vertical sliding rail 51, they can also slide along the vertical sliding rail 51. That is, by rotating the vertical knob 72, the vertical screw rod 71 can be rotated, and then the threaded transmission connection between the vertical screw rod 71 and the vertical nut column 73 enables the rotating vertical screw rod 71 to drive the vertical nut column 73 to move linearly along the axial direction of the vertical nut column 73, thereby driving the vertical sliding block 76 to move vertically along the vertical sliding rail 51.

[0068] Secondly, the vertical sliding block 76 is sleeved on the vertical nut column 73 and can move along the axial direction of the vertical nut column 73, so that by rotating the vertical handle 75, the distance between the vertical sliding block 76 and the vertical limiting plate 74 can be shortened, which is equivalent to making the vertical sliding block 76 and the vertical limiting plate 74 tightly hold the vertical sliding rail 51, thereby increasing the sliding resistance and making the adjustment more precise, and even finally forming a locked state, so that the vertical moving mechanism 70 is fixed on the vertical sliding rail 51.

[0069] As shown in Figures 8 to 11As shown, preferably, the vertical slider 76 is provided with a horizontal sliding rail 77 at one end, and the horizontal moving mechanism 80 is provided with a horizontal screw rod 81, a horizontal screw nut column 83, a horizontal slider 86 and a horizontal handle 85, the horizontal screw rod 81 is rotationally connected to the horizontal sliding rail 77, and the horizontal screw nut column 83 is threadedly connected to the horizontal screw rod 81 through a screw hole.

[0070] Specifically, the horizontal screw rod 81 is provided with a horizontal knob 82 at one end, the horizontal knob 82 is fixedly connected to the horizontal screw rod 81, and is used for rotating operation of the horizontal screw rod 81. The horizontal screw nut column 83 is also provided with a screw hole corresponding to the position of the horizontal screw rod 81, and the inner wall of the screw hole is provided with an internal thread, and the outer wall of the horizontal screw rod 81 is provided with an external thread, the internal thread and the external thread are matched with each other to form a corresponding threaded transmission connection. Similarly, the horizontal slider 86 and the horizontal limiting plate 84 are abutted on both sides of the horizontal sliding rail 77, but can also slide along the horizontal sliding rail 77. That is, by rotating the horizontal knob 82, the horizontal screw rod 81 can be rotated, and then the threaded transmission connection between the horizontal screw rod 81 and the horizontal screw nut column 83 can drive the horizontal screw nut column 83 to move linearly along its axial direction, so as to drive the horizontal slider 86 to move horizontally along the horizontal sliding rail 77.

[0071] Secondly, the horizontal slider 86 is sleeved on the horizontal screw nut column 83 and can move along the axial direction of the horizontal screw nut column 83, so that by rotating the horizontal handle 85, the distance between the horizontal slider 86 and the horizontal limiting plate 84 can be shortened, which is equivalent to making the horizontal slider 86 and the horizontal limiting plate 84 tightly hold the horizontal sliding rail 77, so as to increase the sliding resistance, so that the adjustment can be more refined, and even finally form a locked state, so that the horizontal moving mechanism 80 is fixed on the horizontal sliding rail 77.
