Description

Technical Field

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

[0002] When a firearm is in use, in order to accurately hit a target, an optical sight is usually installed, such as a red dot sight. For close-range targets, using a red dot sight can accurately lock the target. However, since the red dot sight has no magnification, when the target is relatively far away, such as when the target distance exceeds 100 meters, a doubler needs to be used. The magnification of the doubler is usually about 3 to 6 times. Using the doubler can clearly see the target hundreds of meters away, that is, accurate aiming can be achieved.

[0003] When using a doubler in combination with a red dot sight, sometimes the red dot of the red dot sight is not at the center of the field of view of the doubler. It is necessary to adjust the field of view of the doubler so that the field of view of the doubler is aligned with the red dot of the red dot sight. Only in this way can the user obtain a comfortable visual effect when using it. The existing adjustment methods are all to adjust the field of view of the doubler through the adjustment knob on the doubler to achieve alignment with the red dot of the red dot sight. Before the doubler is used in combination with the red dot sight, its field of view is usually already adjusted. When used in combination with the red dot sight, the field of view of the doubler needs to be readjusted. This will cause the doubler after the field of view is adjusted to have to readjust the field of view again when used in combination with the red dot sights on other firearms. It is very troublesome. Especially when the shooter carries multiple doublers with different magnifications, each time a different magnification doubler is replaced, the field of view of each doubler needs to be readjusted, which is both time-consuming and troublesome to operate, bringing great inconvenience to the shooter. Summary of the Invention

[0004] The purpose 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, including a base, a flip structure for mounting an aiming sight, and a rotation axis. The flip structure is rotatably arranged on the base through the rotation axis, and further includes a ball head part, a central axis, and an adjustment seat. A first accommodation cavity is provided on the flip structure, and a ball socket is provided on the inner wall of the first accommodation cavity. One end of the ball head part is provided with a ball head, and the ball head is accommodated in the ball socket. The other end of the ball head part is fixedly arranged on one end of the rotation axis. One end of the central axis is fixedly arranged on the other end of the rotation axis. The adjusting base is provided with a second accommodating cavity. The other end of the central axis is inserted into the second accommodating cavity. The adjusting base is provided with a connecting part, and the connecting part is fixedly arranged on the flipping structure. The adjusting base is provided with an adjusting component, and the adjusting component can adjust the positions of the central axis in the left - right direction and up - down direction in the second accommodating cavity.

[0006] For the flipping bracket of the present invention, the magnifier is installed on the flipping structure, and the base is installed on the firearm. The magnifier is used in combination with the red - dot sight on the firearm. The magnifier can be flipped on the base through the flipping structure to adjust the position of the magnifier. When using the magnifier in combination with the red - dot sight, if the red dot of the red - dot sight is not at the center of the field of view of the magnifier, the positions of the central axis in the left - right direction and up - down direction in the second accommodating cavity are adjusted through the adjusting component. Since the central axis is fixedly arranged on the flipping axis, the adjusting base will move in the left - right direction and up - down direction relative to the central axis. Since the ball head of the ball head is accommodated in the ball socket of the flipping structure, the adjusting base can drive the flipping structure to swing in the left - right direction and up - down direction with the ball head on the ball head as the fulcrum through the connecting part. Thus, the magnifier on the flipping structure swings in the left - right direction and up - down direction on the base with the ball head as the fulcrum, so that the field of view of the magnifier is aligned with the red dot of the red - dot sight. In this way, there is no need to adjust the field of view of the magnifier through the adjusting knob on the magnifier. Even when the shooter carries multiple magnifiers with different magnifications, each time a different - magnification magnifier is replaced, only by adjusting the adjusting component on the flipping bracket can the field of view of the magnifier be aligned with the red dot of the red - dot sight. The operation is simple and fast, which brings great convenience to the shooter. The flipping bracket of the present invention has a simple structure. The field of view of the magnifier can be quickly adjusted through the adjusting component on the adjusting base, and it can be applied to magnifiers with different magnifications, and has a wide application range.

[0007] Preferably, it further includes a steel ball and a locking screw. The flipping structure is provided with a threaded hole. 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. The ball head is provided with a concave cavity. A 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.

[0008] Therefore, the steel balls can circumferentially limit the ball head, that is, the ball head cannot rotate circumferentially relative to the inner wall surface of the ball socket. The flipping structure can only swing with the ball head as the fulcrum. When the flipping structure flips on the base, the flipping structure can drive the ball head to rotate synchronously through the steel balls. The ball head drives the rotating shaft to rotate synchronously, and the rotating shaft drives the central shaft to rotate synchronously. At the same time, the flipping structure drives the adjusting seat to flip synchronously through the connecting part. In this way, the flipping structure, the ball head part, the rotating shaft, the central shaft, and the adjusting seat can flip on the base as a whole. When the doubler is needed, the flipping structure abuts against the base. When the doubler is not needed, the flipping structure flips to a state where it forms a 90-degree angle with the base.

[0009] Preferably, the number of steel balls, locking screws, threaded holes, and concave cavities is three. The three concave cavities are evenly distributed on the ball head. A part of each steel ball is accommodated in one concave cavity, and the other part of each steel ball is accommodated in one threaded hole. The three locking screws are respectively screwed into the three threaded holes, and the ends of the three locking screws respectively abut against the three steel balls.

[0010] Therefore, the three steel balls can evenly limit the ball head circumferentially. When the flipping structure flips on the base, the ball head part can form a stable whole with the flipping structure to flip synchronously.

[0011] Preferably, the adjusting assembly includes a left-right adjusting assembly and an up-down adjusting assembly. The left-right adjusting assembly can adjust the position of the central shaft in the second accommodating cavity in the left-right direction, and the up-down adjusting assembly can adjust the position of the central shaft in the second accommodating cavity in the up-down direction.

[0012] Therefore, by adjusting the position of the central shaft in the second accommodating cavity in the left-right direction through the left-right adjusting assembly, the adjusting seat will move in the left-right direction relative to the central shaft. The adjusting seat drives the flipping structure to swing in the left-right direction with the ball head on the ball head part as the fulcrum through the connecting part. By adjusting the position of the central shaft in the second accommodating cavity in the up-down direction through the up-down adjusting assembly, the adjusting seat will move in the up-down direction relative to the central shaft. The adjusting seat drives the flipping structure to swing in the up-down direction with the ball head on the ball head part as the fulcrum through the connecting part.

[0013] Preferably, it further includes a thimble, a spring and a spring cover. The adjusting seat is provided with a first threaded adjusting hole, a second threaded adjusting hole and a third threaded adjusting hole. The axes of the first threaded adjusting hole and the second threaded adjusting hole are vertically arranged. The axis of the third threaded adjusting hole is arranged at an obtuse angle with the axis of the first threaded adjusting hole, and the axis of the third threaded adjusting hole is arranged at an obtuse angle with the axis of the second threaded adjusting hole. The left-right adjusting component is screwed in the first threaded adjusting hole and the end of the left-right adjusting component abuts against the central shaft. The up-down adjusting component is screwed in the second threaded adjusting hole and the end of the up-down adjusting component abuts against the central shaft. The thimble and the spring are accommodated in the third threaded adjusting hole. One end of the thimble abuts against the central shaft, one end of the spring abuts against the other end of the thimble, and the other end of the spring abuts against the spring cover. The spring cover is screwed in the third threaded adjusting hole.

[0014] Therefore, under the action of the spring, by operating the left-right adjusting component, the overall swing of the adjusting seat and the flipping structure in the left-right direction can be realized, and by operating the up-down adjusting component, the overall swing of the adjusting seat and the flipping structure in the up-down direction can be realized.

[0015] Preferably, the included angle between the axis of the third threaded adjusting hole and the axis of the first threaded adjusting hole is 135 degrees, and the included angle between the axis of the third threaded adjusting hole and the axis of the second threaded adjusting hole is 135 degrees.

[0016] Therefore, the included angles between the axis of the third threaded adjusting hole and the axes of the first threaded adjusting hole and the second threaded adjusting hole being both 135 degrees can ensure that the acting forces of the thimble on the central shaft in the horizontal and vertical directions are consistent, making the forces on the central shaft in the horizontal and vertical directions balanced.

[0017] Preferably, the left-right adjusting component includes a left-right adjusting bolt, a first threaded seat, a first fixing cap, a first compression spring and a first ball. The first threaded seat is screwed in the first threaded adjusting hole. The left-right adjusting bolt is screwed in the first threaded seat, and the end of the left-right adjusting bolt abuts against the central shaft. A first tooth groove is provided on the inner wall of the first threaded seat. A first accommodating through hole perpendicular to its axis is provided on the left-right adjusting bolt. 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 against the first fixing cap, the other end of the first compression spring abuts against one end of the first ball, and the other end of the first ball extends out from the outer wall of the left-right adjusting bolt and abuts against the first tooth groove, and / or The up and down adjustment assembly includes an up and down adjusting bolt, 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 up and down adjusting bolts are rotated in the second threaded seat. The ends of the up and down adjusting bolts abut on the central axis. A circle of second tooth grooves is provided on the inner wall of the second threaded seat. The up and down adjusting bolts are provided with a second accommodating through hole arranged perpendicular to the axis thereof. 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 up and down adjusting bolts and abuts on the second tooth groove.

[0018] Therefore, when the left and right adjusting bolts are screwed, the adjusting seat will move left and right relative to the central axis, and the adjusting seat drives the flip structure through the connecting portion to swing left and right with the ball head on the ball head as a fulcrum. When the up and down adjusting bolts are screwed, the adjusting seat will move up and down relative to the central axis, and the adjusting seat drives the flip structure through the connecting portion to swing up and down with the ball head on the ball head as a fulcrum. When the left and right adjusting bolts are screwed, the first balls extending from the outer walls of the left and right adjusting bolts will rotate synchronously, and the first balls will poke the first tooth groove on the inner wall of the first threaded seat to make a poke sound, so that the shooter can adjust the position according to the poke sound. The sound of movement 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.

[0019] Preferably, it also includes a ball head pressing ring, the inner wall of the port of the first accommodating cavity is provided with a first internal thread, the ball head pressing ring is screwed into the first internal thread, and the edge of the first end of the ball head pressing ring can be pressed against the ball head.

[0020] 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.

[0021] 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.

[0022] Therefore, the cover body can protect the components in the second accommodating chamber, preventing dust or foreign matter from entering the second accommodating chamber through the port of the second accommodating chamber and affecting the cooperation between the adjustment component and the central axis.

[0023] Preferably, an arc-shaped protrusion for supporting the flipping structure is provided at a position on the base near the first accommodating cavity.

[0024] Therefore, the flipping structure can swing smoothly in the up-down direction and left-right direction on the base with the arc-shaped protrusion as the fulcrum. BRIEF DESCRIPTION OF THE DRAWINGS
