Description

Technical Field

[0001] This utility model relates to the field of aiming scopes, specifically to a universal swing mechanism and an aiming scope. Background Technology

[0002] The scope with an external ballistic and windage compensation mechanism is different from traditional scopes that rely on a swing-and-reverse image system to achieve ballistic and windage compensation. This scope mainly includes a scope body containing an imaging lens group, a ball joint, an external ballistic and windage compensation mechanism, and a support base. The ball joint is the key structure of this scope; one end of the scope body is mounted on the ball joint, which serves as the apex of a cone, allowing for arbitrary swinging within a certain cone angle to achieve ballistic and windage compensation.

[0003] Current ball joint designs primarily utilize a structure similar to a spherical bearing. A small portion of the scope's outer shell is machined into a spherical shape, while a part of the support is also machined into a spherical shell. These two are nested together, allowing the scope to swing freely within a certain taper. However, because spherical structures are difficult to manufacture, and the spherical portion of the scope is located outside the optical lens group, the ball joint size of scopes implementing this structure is generally large to avoid affecting light propagation through the internal optical lenses. This causes significant inconvenience in the application of this type of scope and limits its usage scenarios. Furthermore, due to the large gap between the spherical shell and the spherical surface, there is a certain delay in the reverse movement during adjustment, which is detrimental to the adjustment of the scope's ballistic compensation and windage compensation. Utility Model Content

[0004] The primary objective of this invention is to provide a universal swing mechanism that is simple in structure, easy to operate, and small in size.

[0005] The second objective of this invention is to provide a sight that includes the aforementioned universal swing mechanism.

[0006] To achieve the aforementioned first objective, this utility model provides a universal swing mechanism, comprising: a left-right swing assembly and a right-up swing assembly. The lower part of the right-up swing assembly is disposed on the left-right swing assembly. The right-up swing assembly can rotate around a first axis. Mounting parts are respectively provided on both sides of the upper part of the right-up swing assembly. The two mounting parts are coaxially arranged. The mounting parts can rotate around a second axis, which is perpendicular to the first axis. The mounting part includes a horizontal shaft pin and a horizontal shaft sleeve. The horizontal shaft pin is rotatably inserted into the horizontal shaft sleeve. A first gap elimination structure is provided between the horizontal shaft pin and the horizontal shaft sleeve.

[0007] As can be seen from the above scheme, by setting two mounting parts for mounting and fixing products such as scopes, the scopes can rotate left and right around the first axis and up and down around the second axis, which is beneficial for wind drift compensation and ballistic compensation of the scope. The up and down swing assembly is connected to the left and right swing assembly, with single-point support for left and right rotation and two-point support for up and down rotation, which is beneficial for achieving structural compactness and reducing unnecessary structures to achieve weight reduction. By setting a first gap elimination structure, it is beneficial to avoid the impact of the scope's backlash during up and down rotation on aiming accuracy after the scope is installed. This utility model also has the advantages of simple structure, convenient operation and small size.

[0008] A further embodiment is that the up-and-down swing assembly includes a support frame, which includes two support arms arranged opposite each other. Two mounting parts are respectively mounted on the two support arms. A horizontal shaft sleeve is fitted onto the first end of the horizontal shaft nail, and the second end of the horizontal shaft nail protrudes from the inner wall of the support arm. The axis of the horizontal shaft nail is parallel to the second axis. The first gap elimination structure includes a first conical surface and a second conical surface. The first conical surface is located on the outer side of the first end of the horizontal shaft nail, and the second conical surface is located on the inner side of the horizontal shaft sleeve. The first conical surface and the second conical surface are connected in a mating manner.

[0009] As can be seen from the above scheme, the above settings will not affect the relative rotation of the horizontal axis pin and the horizontal axis sleeve, and will also eliminate the gap between the horizontal axis pin and the horizontal axis sleeve, so as to avoid the impact of the space return on the aiming accuracy when adjusting the supplementary amount of the scope.

[0010] A further option is to include a fastening pin in the mounting section, which passes through the support arm and connects to the horizontal shaft sleeve, with the fastening pin intersecting the axis of the horizontal shaft sleeve.

[0011] As can be seen from the above scheme, the above settings help to lock the horizontal shaft sleeve onto the support arm and eliminate the gap between the horizontal shaft sleeve and the horizontal shaft pin.

[0012] A further option is that the support frame also includes a connecting part, which is connected between the two support arms. A first mounting hole is provided in the middle of the connecting part, and the axis of the first mounting hole is parallel to the first axis.

[0013] A further embodiment is that the left-right swinging assembly includes a base, a vertical shaft sleeve, and a vertical shaft pin. The vertical shaft sleeve is disposed inside the base, one end of the vertical shaft pin is rotatably disposed inside the vertical shaft sleeve, and the other end of the vertical shaft pin protrudes from the vertical shaft sleeve. The axis of the vertical shaft pin is parallel to the first axis, and a second gap elimination structure is provided between the vertical shaft pin and the vertical shaft sleeve.

[0014] As can be seen from the above scheme, by setting a second gap elimination structure, it is beneficial to avoid the impact of the backlash on aiming accuracy when the scope is rotated left and right after installation.

[0015] A further option is that the second gap elimination structure includes a third conical surface and a fourth conical surface. The third conical surface is located on the outside of the vertical shaft pin, and the fourth conical surface is located on the upper inner side of the vertical shaft sleeve. The third conical surface and the fourth conical surface are connected in a mating manner.

[0016] As can be seen from the above scheme, the above settings will not affect the relative rotation of the vertical axis pin and the vertical axis sleeve, and will also eliminate the gap between the vertical axis sleeve and the vertical axis pin, so as to avoid the impact of the space return on the aiming accuracy when adjusting the supplementary amount of the scope.

[0017] A further embodiment is that the left and right swinging assembly also includes a pressure ring, which is set inside the vertical shaft sleeve and sleeved on the outside of the second end of the vertical shaft nail. A third gap elimination structure is provided between the vertical shaft sleeve and the pressure ring.

[0018] As can be seen from the above scheme, the above settings will not affect the relative rotation of the vertical axis pin and the vertical axis sleeve, and will also eliminate the gap between the vertical axis sleeve and the vertical axis pin, so as to avoid the impact of the space return on the aiming accuracy when adjusting the supplementary amount of the scope.

[0019] A further option is that the third gap elimination structure includes a fifth conical surface and a sixth conical surface. The fifth conical surface is located on the lower inner side of the vertical shaft sleeve, and the sixth conical surface is located on the outer side of the pressure ring. The fifth conical surface and the sixth conical surface are connected in a mating manner.

[0020] As can be seen from the above scheme, the above settings help to lock the vertical shaft sleeve and the vertical shaft pin, eliminate the gap between them, and prevent them from separating accidentally.

[0021] To achieve the second objective mentioned above, this utility model provides a sight, including a scope body and the aforementioned universal swing mechanism. The scope body is connected to two mounting parts and can rotate around a first axis and / or a second axis.

[0022] As can be seen from the above scheme, the above settings facilitate the left-right and up-down swinging of the scope body, thereby achieving wind drift compensation and ballistic compensation.

[0023] A further design involves providing connection holes on both opposite sides of the middle section of the scope. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0031] Example of a universal swing mechanism:

[0032] See Figure 1 and combined Figure 4 This embodiment provides a universal swing mechanism 10, including a left-right swing assembly 1 and a right-right swing assembly 2. The lower part of the right-right swing assembly 2 is disposed on the left-right swing assembly 1, and the right-right swing assembly 2 can rotate left and right around a first axis, which preferably extends in the vertical direction; mounting parts are respectively provided on both sides of the upper part of the right-right swing assembly 2, and the two mounting parts are coaxially arranged. The mounting parts can rotate around a second axis, which is perpendicular to the first axis, that is, the second axis extends in the horizontal direction. Specifically:

[0033] The left-right swing assembly 1 includes a base 11, a vertical shaft sleeve 12, a vertical shaft nail 13, and a pressure ring 14.

[0034] The base 11 has a second mounting hole 111 along the vertical direction, and the vertical shaft sleeve 12 is disposed in the second mounting hole 111 and detachably connected to the second mounting hole 111. The detachable connection includes threaded connection, snap-fit ​​connection and magnetic connection, etc., and in this embodiment, a threaded connection is preferred.

[0035] The upper part of the vertical shaft nail 13 is disposed inside and fixedly connected to the upper and lower swing member 2. The lower part of the vertical shaft nail 13 extends downward through the upper and lower swing member 2 and is inserted into the vertical shaft sleeve 12. The vertical shaft nail 13 and the vertical shaft sleeve 12 can rotate relative to each other to achieve a rotatable connection with the left and right swing assembly 1. The first axis is the axis of the vertical shaft nail 13.

[0036] A second gap-eliminating structure is provided between the vertical shaft pin 13 and the vertical shaft sleeve 12. The second gap-eliminating structure includes a third conical surface 131 and a fourth conical surface 121. The third conical surface 131 is provided on the outer side between the two ends of the vertical shaft pin 13. The third conical surface 131 is a third annular surface, and the diameter of the third annular surface gradually narrows from top to bottom. The fourth conical surface 121 is provided on the upper inner side of the vertical shaft sleeve 12. The third conical surface 131 and the fourth conical surface 121 are connected and can move relative to each other. The deeper the vertical shaft pin 13 is inserted into the vertical shaft sleeve 12, the tighter the connection between the third conical surface 131 and the fourth conical surface 121, and the smaller the gap between the vertical shaft pin 13 and the vertical shaft sleeve 12. In this embodiment, the vertical shaft pin 13 can immediately stop rotating and rotate back after rotating relative to the vertical shaft sleeve 12 by a preset angle, so that the vertical shaft pin 13 can stably stop at the current rotation angle without external force.

[0037] The third conical surface 131 and the fourth conical surface 121 are connected in a mating manner, which also helps to avoid the impact of backlash on aiming accuracy when adjusting the windage compensation of the sight. In this embodiment, backlash refers to the phenomenon of delayed reverse movement caused by clearance or poor meshing in mechanical transmission. For example, in a screw mechanism, when the screw changes direction, the nut needs to rotate a certain angle to respond; this clearance is called backlash.

[0038] The pressure ring 14 is disposed inside the lower part of the vertical shaft sleeve 12 and sleeved on the lower outer part of the vertical shaft nail 13. The pressure ring 14 is detachably connected to the lower part of the vertical shaft nail 13. The detachable connection includes threaded connection, snap-fit ​​connection, and magnetic connection, etc. In this embodiment, a threaded connection is preferred. When the vertical shaft nail 13 rotates relative to the vertical shaft sleeve 12, the vertical shaft nail 13 can drive the pressure ring 14 to rotate synchronously.

[0039] A third gap-eliminating structure is provided between the vertical shaft sleeve 12 and the pressure ring 14. The third gap-eliminating structure includes a fifth conical surface 122 and a sixth conical surface 141. A fifth conical surface 122 is also provided on the lower inner side of the vertical shaft sleeve 12. The fifth conical surface 122 is a second annular surface, and its diameter gradually narrows from bottom to top. A sixth conical surface 141 is provided on the outer side of the pressure ring 14, and the fifth conical surface 122 and the sixth conical surface 141 are fitted together. The deeper the pressure ring 14 is embedded between the vertical shaft sleeve 12 and the vertical shaft pin 13, the tighter the connection between the fifth conical surface 122 and the sixth conical surface 141, and the smaller the gap between the vertical shaft sleeve 12 and the pressure ring 14. In this embodiment, the vertical shaft pin 13 drives the pressure ring 14 to rotate relative to the vertical shaft sleeve 12 by a preset angle, and the rotation can immediately stop and reverse. This ensures that the vertical shaft pin 13 can stably stop at the current rotation angle without external force.

[0040] The pressure ring 14 can also lock the vertical shaft pin 13 and the vertical shaft sleeve 12 in the vertical direction to prevent them from separating accidentally.

[0041] See Figure 1 and Figure 2and combined Figure 4 The vertical swing assembly 2 includes a support frame 21. The support frame 21 has an inverted "U" shape and includes a connecting part 211 and two opposing support arms 212. The connecting part 211 connects the two support arms 212. A first mounting hole 2111 is provided in the middle of the connecting part 211, and the first axis is collinear with the axis of the first mounting hole 2111. The first mounting hole 2111 is used for detachable connection with the upper part of the vertical shaft nail 13. The detachable connection includes threaded connection, snap-fit ​​connection and magnetic connection. In this embodiment, a threaded connection is preferred.

[0042] The two mounting parts are respectively mounted on the two support arms 212, and the upper part of the support arms 212 has a third mounting hole 2121 in the horizontal direction. The mounting part is set in the third mounting hole 2121.

[0043] The mounting section includes a horizontal shaft pin 22, a horizontal shaft sleeve 23, and a fastening pin 24. The horizontal shaft sleeve 23 is rotatably fitted over the horizontal shaft pin 22, and a first gap-eliminating structure is provided between the horizontal shaft pin 22 and the horizontal shaft sleeve 23. Specifically:

[0044] A horizontal shaft sleeve 23 is fitted onto the first end of a horizontal shaft nail 22, and the second end of the horizontal shaft nail 22 protrudes from the inner wall of the support arm 212. The horizontal shaft nail 22 can rotate relative to the horizontal shaft sleeve 23, and its second axis is collinear with the axis of the horizontal shaft nail 22.

[0045] The first gap-eliminating structure includes a first conical surface 221 and a second conical surface 231. The first conical surface 221 is provided on the outer side of the first end of the horizontal shaft nail 22. The first conical surface 221 is a first annular surface, and its diameter gradually expands from the first end of the horizontal shaft nail 22 towards its center. Correspondingly, the second conical surface 231 is provided on the inner side of the horizontal shaft sleeve 23. The first conical surface 221 and the second conical surface 231 are connected and can move relative to each other. The deeper the horizontal shaft sleeve 23 is fitted onto the horizontal shaft nail 22, the tighter the connection between the first conical surface 221 and the second conical surface 231, and the smaller the gap between the horizontal shaft sleeve 23 and the horizontal shaft nail 22. In this embodiment, the horizontal shaft nail 22 is designed to stop rotating immediately and rotate back after rotating relative to the horizontal shaft sleeve 23 by a preset angle, so that the horizontal shaft nail 22 can stably stop at the current rotation angle without external force.

[0046] The first conical surface 221 and the second conical surface 231 are connected in a cooperative manner, which also helps to avoid the impact of space return on aiming accuracy when adjusting the ballistic replenishment amount of the scope.

[0047] The horizontal shaft sleeve 23 is threaded into the third mounting hole 2121. To prevent the horizontal shaft sleeve 23 from loosening, the mounting part in this embodiment also includes a fastening screw 24. Specifically, the upper part of the support arm 212 also has a fourth mounting hole 2122. One end of the fourth mounting hole 2122 protrudes from the upper end face of the support arm 212, and the other end of the fourth mounting hole 2122 communicates with the third mounting hole 2121. The fastening screw 24 is disposed in the fourth mounting hole 2122 and connected to the horizontal shaft sleeve 23. The fastening screw 24 intersects the axis of the horizontal shaft sleeve 23, thereby locking the horizontal shaft sleeve 23. The fastening screw is preferably a screw.

[0048] To facilitate the connection between the universal swing mechanism 10 and the gun in this embodiment, a mounting plate 15 is connected to one side of the base 11. The mounting plate 15 is detachably connected to the gun. The detachable connection includes screw connection, snap-fit ​​connection and magnetic connection. In this embodiment, screw connection is preferred.

[0049] The universal swing mechanism of this embodiment is applicable to aiming scopes, fine-tuning supports for other optical instruments, and precision positioning mechanisms for robot joints.

[0050] Example of a sight:

[0051] See Figures 2 to 6 The aiming scope provided in this embodiment includes a scope body 20 and a universal swing mechanism 10 as described in the above embodiment. The middle part of the scope body 20 is connected to two mounting parts, and the scope body 20 can rotate around a first axis and / or a second axis, that is, the scope body 20 can swing left and right and / or up and down relative to the base 11.

[0052] In one embodiment, a protrusion is provided in the middle of the mirror body 20, and flat surfaces are provided on both sides of the protrusion. A connecting hole 201 is provided on the flat surface, and the connecting hole 201 is not in communication with the interior of the mirror body 20. The second end of the horizontal axis nail 22 is detachably connected to the connecting hole 201, preferably by a threaded connection.

[0053] In another embodiment, the connecting holes can be directly located on opposite sides of the middle of the mirror body, and the connecting holes do not communicate with the interior of the mirror body. The second end of the transverse axis pin is detachably connected to the connecting hole, preferably by a threaded connection.

[0054] In this embodiment, when the mirror body 20 rotates around the first axis, the mirror body 20 can swing to the left or right, at which time the wind deflection compensation amount can be adjusted, such as... Figure 5 As shown.

[0055] In this embodiment, when the scope body 20 rotates around the second axis, the scope body 20 can swing upwards or downwards, at which time the ballistic compensation amount can be adjusted, such as... Figure 6 As shown.

[0056] The installation sequence of the sight 20 and the universal swing mechanism 10 in this embodiment is as follows:

[0057] (1) First assemble the up-and-down swing assembly 2 and the sight 20, as follows:

[0058] First, screw the upper part of the vertical shaft nail 13 into the support frame 21, so that the lower part of the vertical shaft nail 13 protrudes downward.

[0059] The second step is to place the scope 20 into the support frame 21, and then thread the horizontal axis pin 22 through the third mounting hole 2121 of the support frame 21 to connect it with the scope 20.

[0060] The third step is to screw the horizontal shaft sleeve 23 into the third mounting hole 2121, so that the horizontal shaft sleeve 23 is fitted on the outside of the horizontal shaft nail 22, and the horizontal shaft nail 22 can rotate relative to the horizontal shaft sleeve 23.

[0061] Fourth step, screw the fastening pin 24 into the fourth mounting hole 2122 so that the fastening pin 24 is connected to the horizontal shaft sleeve 23;

[0062] Fifth, install the horizontal shaft nail 22 and horizontal shaft sleeve 23 on the other side according to the above steps to form a small assembly.

[0063] (2) Connect the small component from the previous step to the left and right swinging component 1, as follows:

[0064] Step 6: Install the vertical shaft sleeve 12 into the base 11;

[0065] Step 7: Insert the lower part of the vertical shaft nail 13 in the small component into the vertical shaft sleeve 12 from top to bottom. The vertical shaft nail 13 can rotate relative to the vertical shaft sleeve 12.

[0066] Step 8: Screw the pressure ring 14 into the lower outer part of the vertical shaft nail 13 from bottom to top. The pressure ring 14 is inserted into the vertical shaft sleeve 12 and can rotate relative to the vertical shaft sleeve 12.

[0067] In other embodiments, the left-right swing component 1 can be assembled first, then the sight 20 and the up-down swing component 2 can be assembled, and finally the up-down swing component 2 and the left-right swing component 1 can be assembled together.

[0068] After the scope 20 is assembled with the universal swing mechanism 10, the user can adjust the up-and-down swing angle and the left-and-right swing angle of the scope 20 according to the actual aiming needs.

[0069] Once the vertical swing angle is adjusted to the correct position, the horizontal axis pin 22 can be fixed by tightening the horizontal axis sleeve 23 and the fastening pin 24, thereby locking the current vertical angle of the scope 20.

[0070] Once the left and right swing angles are adjusted to the correct position, the vertical axis pin 13 can be fixed by tightening the pressure ring 14, thereby locking the current left and right swing angle of the sight 20.

[0071] In summary, this invention, by providing two mounting parts for mounting and fixing products such as scopes, allows the scope to rotate left and right around a first axis and up and down around a second axis, which is beneficial for wind drift compensation and ballistic compensation. The up-and-down swing assembly is connected to the left-and-right swing assembly, with single-point support for left-and-right rotation and two-point support for up-and-down rotation, which not only contributes to the compactness of the structure but also reduces unnecessary structural elements, thus achieving weight reduction. By providing a first gap elimination structure, the impact of airflow during the up-and-down rotation of the scope on aiming accuracy is avoided. This invention also has the advantages of simple structure, convenient operation, and small size.
