Description

Technical Field

[0001] The invention relates to the field of sights, and in particular to an adjustable flip bracket. Background Art

[0002] When a gun is in use, in order to accurately hit the target, it is usually equipped with an optical sight, such as a red dot sight. In this way, for close-range targets, the red dot sight can be used to accurately lock the target. However, since the red dot sight has no magnification, when the target is farther away, such as when the target distance exceeds 100 meters, it needs to be paired with a magnifying mirror. The magnification of the magnifying mirror is usually around 3 to 6 times. Using a magnifying mirror, you can see the target clearly over 100 meters away, and achieve precise aiming.

[0003] When using a telescope with a red dot sight, sometimes the red dot of the red dot sight is not in the center of the telescope's field of view. It is necessary to adjust the telescope's field of view so that the telescope's field of view is aligned with the red dot of the red dot sight. Only in this way can the user get a comfortable visual effect when using it. The existing adjustment method is to adjust the telescope's field of view through the adjustment knob on the telescope to achieve alignment with the red dot of the red dot sight. The field of view of the telescope is usually adjusted before being used with a red dot sight. When used with a red dot sight, the field of view of the telescope needs to be readjusted. This will result in the telescope, after the field of view is adjusted, having to be readjusted when used with red dot sights on other guns. This is very troublesome, especially when the shooter carries multiple telescopes of different magnifications with him. Each time a telescope of a different magnification is changed, the field of view of each telescope needs to be readjusted, which wastes time and is troublesome to operate, causing great inconvenience to the shooter. Summary of the Invention

[0004] The object of the present invention is to provide an adjustable flip bracket to solve at least one of the above technical problems.

[0005] The present invention provides an adjustable flip bracket, comprising a base, a flip structure for mounting a sight, and a flip axis, wherein the flip structure is rotatably arranged on the base via the flip axis, and further comprising a ball head, a central axis, and an adjustment seat.

[0006] A first accommodating cavity is provided on the flip structure, and a ball socket is provided on the inner wall of the first accommodating cavity.

[0007] One end of the ball head is provided with a ball head, which is accommodated in the ball socket, and the other end of the ball head is fixed on one end of the flip shaft.

[0008] One end of the central shaft is fixed on the other end of the flip shaft.

[0009] A second accommodating cavity is provided on the adjustment seat, and the other end of the central axis is inserted into the second accommodating cavity. A connecting portion is provided on the adjustment seat, and the connecting portion is fixed on the flip structure. An adjustment component is provided on the adjustment seat, and the adjustment component can adjust the position of the central axis in the left and right directions and the up and down directions in the second accommodating cavity.

[0010] The flip bracket of the present invention has a magnifying mirror installed on the flip structure, and a base installed on the gun. The magnifying mirror is used in conjunction with the red dot sight on the gun. The magnifying mirror can be flipped on the base through the flip structure to adjust the position of the magnifying mirror. When the magnifying mirror is used in conjunction with the red dot sight, if the red dot of the red dot sight is not in the center of the field of view of the magnifying mirror, the position of the central axis in the second accommodating cavity is adjusted in the left and right directions and the up and down directions through the adjustment component. Since the central axis is fixed on the flip axis, the adjustment seat will move in the left and right directions and the up and down directions relative to the central axis. Since the ball head of the ball head is accommodated in the ball socket of the flip structure, the adjustment seat can drive the flip structure to move in the left and right directions and the up and down directions with the ball head on the ball head as the fulcrum through the connecting part. The flip bracket of the present invention has a simple structure and the field of view of the magnifier can be quickly adjusted by adjusting the adjustment component on the adjustment seat. It can be applied to magnifiers of different magnifications and has a wide range of applications.

[0011] Preferably, it also includes a steel ball and a locking screw. A threaded hole is provided on the flip structure. One end of the threaded hole is located on the inner wall surface of the ball socket, and the other end of the threaded hole is located on the outer wall of the first accommodating cavity. A concave cavity is provided on the ball head. Part of the steel ball is accommodated in the concave cavity, and the other part of the steel ball is accommodated in the threaded hole. The locking screw is screwed into the threaded hole and the end of the locking screw abuts against the steel ball.

[0012] Therefore, the steel ball can limit the ball head circumferentially, that is, the ball head cannot rotate circumferentially relative to the inner wall of the ball socket, and the flip structure can only swing with the ball head as the fulcrum. When the flip structure flips on the base, the flip structure can drive the ball head to rotate synchronously through the steel ball, the ball head drives the flip axis to rotate synchronously, and the flip axis drives the center axis to rotate synchronously. At the same time, the flip structure drives the adjustment seat to flip synchronously through the connecting part, so that the flip structure, ball head, flip axis, center axis, and adjustment seat can be flipped on the base as a whole. When the magnifying glass is needed, the flip structure is abutted against the base. When the magnifying glass is not used, the flip structure flips to a state where it forms a 90-degree angle with the base.

[0013] Preferably, the number of steel balls, locking screws, threaded holes and concave cavities is three, and the three concave cavities are evenly distributed on the ball head. Part of each steel ball is accommodated in a concave cavity, and the other part of each steel ball is accommodated in a threaded hole. The three locking screws are respectively screwed into the three threaded holes and the ends of the three locking screws are respectively abutted against the three steel balls.

[0014] Therefore, the three steel balls can evenly limit the position of the ball head in the circumferential direction. When the flip structure flips on the base, the ball head and the flip structure can form a stable whole and flip synchronously.

[0015] Preferably, the adjustment component includes a left-right adjustment component and an up-down adjustment component. The left-right adjustment component can adjust the left-right position of the central axis in the second accommodating cavity, and the up-down adjustment component can adjust the up-down position of the central axis in the second accommodating cavity.

[0016] Therefore, by adjusting the left and right position of the central axis in the second accommodating chamber through the left and right adjustment components, the adjustment seat will move in the left and right directions relative to the central axis, and the adjustment seat drives the flip structure through the connecting part to swing in the left and right directions with the ball head on the ball head as the fulcrum. By adjusting the up and down position of the central axis in the second accommodating chamber through the up and down adjustment components, the adjustment seat will move in the up and down directions relative to the central axis, and the adjustment seat drives the flip structure through the connecting part to swing in the up and down directions with the ball head on the ball head as the fulcrum.

[0017] Preferably, it also includes a thimble, a spring and a spring cover, and the adjustment seat is provided with a first threaded adjustment hole, a second threaded adjustment hole and a third threaded adjustment hole, the axis of the first threaded adjustment hole and the axis of the second threaded adjustment hole are arranged vertically, the axis of the third threaded adjustment hole and the axis of the first threaded adjustment hole are arranged at an obtuse angle, and the axis of the third threaded adjustment hole and the axis of the second threaded adjustment hole are arranged at an obtuse angle, the left and right adjustment components are rotated in the first threaded adjustment hole and the ends of the left and right adjustment components abut on the central axis, the up and down adjustment components are rotated in the second threaded adjustment hole and the ends of the up and down adjustment components abut on the central axis, the thimble and the spring are accommodated in the third threaded adjustment hole, one end of the thimble abuts on the central axis, one end of the spring abuts on the other end of the thimble, the other end of the spring abuts on the spring cover, and the spring cover is rotated in the third threaded adjustment hole.

[0018] Therefore, under the action of the spring, the adjustment seat and the flip structure as a whole can be swung in the left and right directions by operating the left and right adjustment components, and the adjustment seat and the flip structure as a whole can be swung in the up and down directions by operating the up and down adjustment components.

[0019] Preferably, the angle between the axis of the third threaded adjustment hole and the axis of the first threaded adjustment hole is 135 degrees, and the angle between the axis of the third threaded adjustment hole and the axis of the second threaded adjustment hole is 135 degrees.

[0020] Therefore, the included angles of 135 degrees between the axis of the third threaded adjustment hole and the axis of the first threaded adjustment hole and the axis of the second threaded adjustment hole can ensure that the force exerted by the pin on the central axis in the horizontal and vertical directions remains consistent, so that the force on the central axis in the horizontal and vertical directions is balanced.

[0021] Preferably, the left and right adjustment components include left and right adjustment bolts, a first threaded seat, a first fixing cap, a first compression spring and a first ball, the first threaded seat is rotated in the first threaded adjustment hole, the left and right adjustment bolts are rotated in the first threaded seat, the ends of the left and right adjustment bolts abut on the central axis, a circle of first tooth grooves is provided on the inner wall of the first threaded seat, the left and right adjustment bolts are provided with a first accommodating through hole arranged perpendicular to their axis, the first fixing cap, the first compression spring and the first ball are all accommodated in the first accommodating through hole, one end of the first compression spring abuts on the first fixing cap, the other end of the first compression spring abuts on one end of the first ball, the other end of the first ball extends from the outer wall of the left and right adjustment bolts and abuts on the first tooth groove, and / or

[0022] The upper and lower adjustment components include upper and lower adjusting bolts, a second threaded seat, a second fixing cap, a second compression spring and a second ball. The second threaded seat is rotated in the second threaded adjustment hole, and the upper and lower adjusting bolts are rotated in the second threaded seat. The ends of the upper and lower adjusting bolts abut on the center axis. A circle of second tooth grooves is provided on the inner wall of the second threaded seat. The upper and lower adjusting bolts are provided with a second accommodating through hole arranged perpendicular to their axis. The second fixing cap, the second compression spring and the second ball are all accommodated in the second accommodating through hole. One end of the second compression spring abuts on the second fixing cap, and the other end of the second compression spring abuts on one end of the second ball. The other end of the second ball extends from the outer wall of the upper and lower adjusting bolts and abuts on the second tooth groove.

[0023] Therefore, when the left and right adjustment bolts are screwed, the adjustment seat will move left and right relative to the central axis, and the adjustment seat drives the flip structure to swing left and right through the connecting portion with the ball head on the ball head as a fulcrum. When the up and down adjustment bolts are screwed, the adjustment seat will move up and down relative to the central axis, and the adjustment seat drives the flip structure to swing up and down through the connecting portion with the ball head on the ball head as a fulcrum. When the left and right adjustment bolts are screwed, the first ball extending from the outer wall of the left and right adjustment bolts will rotate synchronously, and the first ball will poke the first tooth groove on the inner wall of the first threaded seat, making a poke sound, so that the shooter can adjust the gun according to the poke. The movement sound can be used to know the rotation angle of the left and right adjustment bolts, so that the left and right position of the flip structure can be adjusted quantitatively and accurately, so that the field of view of the magnifier on the flip structure is accurately aligned with the red dot of the red dot sight. When the upper and lower adjustment bolts are screwed, the second ball extending from the outer wall of the upper and lower adjustment bolts will rotate synchronously, and the second ball will move the second tooth groove on the inner wall of the second threaded seat, making a moving sound, so that the shooter can know the rotation angle of the upper and lower adjustment bolts according to the moving sound, so that the upper and lower position of the flip structure can be adjusted quantitatively and accurately, so that the field of view of the magnifier on the flip structure is accurately aligned with the red dot of the red dot sight.

[0024] Preferably, a ball head pressing ring is further included. A first internal thread is provided on the inner wall of the port of the first accommodating cavity. The ball head pressing ring is screwed into the first internal thread. The edge of the first end of the ball head pressing ring can press against the ball head.

[0025] Therefore, as needed, the tightness of the fit between the ball head and the ball socket can be adjusted by screwing the ball head pressure ring.

[0026] Preferably, a cover body is further included, and a second internal thread is provided on the inner wall of the port of the second accommodating cavity, and the cover body is screwed into the second internal thread.

[0027] Therefore, the cover body can protect the components in the second accommodating cavity, preventing dust or foreign matter from entering the second accommodating cavity through the port of the second accommodating cavity and affecting the cooperation between the adjustment component and the central axis.

[0028] Preferably, an arc-shaped protrusion for supporting the flip structure is provided on the base near the first accommodating cavity.

[0029] Therefore, the flip structure can swing smoothly in the up-down and left-right directions on the base with the arc-shaped protrusion as a fulcrum. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] See Figure 1 , flip structure 2 is used to install the magnifying lens, see Figure 2 and Figure 7The flip structure 2 is rotatably mounted on the base 1 through the flip axis 3, and the magnifying mirror is mounted on the flip structure 2. The magnifying mirror can be flipped on the base 1 through the flip structure 2 to adjust the position of the magnifying mirror. In order to realize that the flip structure 2 is rotatably mounted on the base 1 through the flip axis 3, the matching structural relationship among the flip structure 2, the flip axis 3 and the base 1 can use the structure in the utility model patent with the announcement number CN221173134U and the name “Flipping mechanism for a sight”. When the flip structure 2 is against the base 1, the flip axis 3 is automatically locked. When the flip structure 2 is flipped to be arranged at 90 degrees with the base 1, the flip axis 3 is automatically locked, thereby realizing a rapid 90-degree flip of the magnifying mirror. The matching structural relationship among the flip structure 2, the flip axis 3 and the base 1 can also adopt other flip bracket structures for installing sights to realize that the flip structure 2 is rotatably mounted on the base 1 through the flip axis 3.

[0046] See Figure 3 and Figure 5 A first accommodating cavity 21 is formed on the flip structure 2, a ball socket 22 is formed on the inner wall of the first accommodating cavity 21, and a ball head 41 adapted to the ball socket 22 is formed at the right end of the ball head 4, and the ball head 41 is accommodated in the ball socket 22 ( Figure 7 shown).

[0049] See Figure 3 、 Figure 5 and Figure 12The cam 41 is provided with a screw thread 23, and one end of the screw thread 23 is located on the inner wall surface of the ball socket 22, and the other end of the screw thread 23 is located on the outer wall of the first accommodating chamber 21. A concave cavity 411 is formed on the ball head 41, and a part of the steel ball 7 is accommodated in the concave cavity 411, and the other part of the steel ball 7 is accommodated in the threaded hole 23. The locking screw 8 is screwed into the threaded hole 23 and the end of the locking screw 8 abuts against the steel ball 7. The steel ball 7 can limit the ball head 41 circumferentially, that is, the ball head 41 cannot rotate circumferentially relative to the inner wall surface of the ball socket 22, and the flip structure 2 can only swing with the ball head 41 as the fulcrum. When the flip structure 2 flips on the base 1, the flip structure 2 can drive the ball head 41 to rotate synchronously through the steel ball 7, and the ball head 4 drives the flip shaft 3 to rotate synchronously, that is, the flip structure 2 can flip on the base 1 with the flip shaft 3 and the ball head 4 as the rotation center.

[0050] See Figure 3 、 Figure 5 and Figure 12 In this embodiment, the number of steel balls 7, locking screws 8, threaded holes 23, and concave cavities 411 is three. The three concave cavities 411 are evenly distributed on the ball head 41. A part of each steel ball 7 is accommodated in a concave cavity 411, and the other part of each steel ball 7 is accommodated in a threaded hole 23. The three locking screws 8 are respectively screwed into the three threaded holes 23 and the ends of the three locking screws 8 are respectively abutted against the three steel balls 7. The three steel balls 7 can evenly limit the circumferential position of the ball head 41. When the flip structure 2 flips on the base 1, the ball head 4 can form a stable whole with the flip structure 2 for synchronous flipping.

When the ball head pressing ring 12 is screwed into the first internal thread 211, the arc surface 121 on the ball head pressing ring 12 is pressed against the ball head 41 ( Figure 7 As shown), the tightness of the fit between the ball head 41 and the ball socket 22 can be adjusted by screwing the ball head pressure ring 12 as needed.

[0052] See Figure 3One end of the central shaft 5 is fixed to the end of the flip shaft 3. Specifically, the right end of the central shaft 5 is formed with a threaded connection portion 51, and the left end of the flip shaft 3 is formed with an internal threaded hole 31. The threaded connection portion 51 on the central shaft 5 is screwed into the internal threaded hole 31 on the flip shaft 3. The central shaft 5, the flip shaft 3, and the ball head 4 are connected together in sequence and arranged coaxially. When the flip structure 2 flips on the base 1, the flip structure 2 can drive the ball head 41 to rotate synchronously through the steel ball 7, the ball head 4 drives the flip shaft 3 to rotate synchronously, and the flip shaft 3 drives the central shaft 5 to rotate synchronously, that is, the flip structure 2 can be flipped on the base 1 with the ball head 4, the flip shaft 3, and the central shaft 5 as the rotation center.

At the same time, the flip structure 2 drives the adjusting seat 6 to flip synchronously through the connecting portion 62, so that the flip structure 2, ball head 4, flip shaft 3, central axis 5, and adjusting seat 6 can be flipped on the base 1 as a whole. When the magnifying mirror needs to be used, the flip structure 2 abuts against the base 1.
