Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in FIGS. 1-5 , in an embodiment of the present invention: an adjustable sighting scope bracket includes a base 110, two groups of clamping components consisting of a support frame 120 and an upper clamping ring 130 are arranged above the base 110, a first chamber 210 and a second chamber 240 are opened on the front and rear sides of the base 110, and a translation mechanism and a lifting mechanism are respectively arranged inside the first chamber 210 and the second chamber 240;

The translation mechanism includes a threaded rod 230 bearing-connected to the inner wall of the first chamber 210, and the outer wall of the threaded rod 230 is threadedly connected to a connecting piece 220 inserted into the first chamber 210;

The lifting mechanism includes a mounting block 250 inserted into the second chamber 240, and a transmission block 260 is slidably connected below the mounting block 250. A threaded groove 270 is provided inside the transmission block 260, and a bolt block 280 is threadedly connected inside the threaded groove 270. The right end of the bolt block 280 is connected to a connecting rod 290 whose bearing is set on the inner wall of the second chamber 240.

In specific operation, when the front support frame 120 needs to be adjusted to move left and right, the threaded rod 230 is rotated, and the threaded connection between the threaded rod 230 and the connecting member 220 can drive the connecting member 220 to move left and right, so that the front support frame 120 can move left and right, ensuring that the two sets of support frames 120 can be parallel to the upper surface of the firearm, avoiding the angle deviation of the sight, and ensuring the accuracy of the sight after installation;

When the height of the rear support frame 120 needs to be adjusted, the connecting rod 290 is rotated to drive the bolt block 280 to rotate. Through the threaded connection between the bolt block 280 and the thread groove 270, the transmission block 260 can be driven to move left and right. The transmission block 260 squeezes and pulls the mounting block 250, so that the mounting block 250 can be adjusted up and down, and the height of the rear support frame 120 can be adjusted, thereby ensuring that the two groups of support frames 120 are on the same horizontal line, avoiding the phenomenon of raising or lowering the sight after installation.

The threaded rod 230 and the right end of the connecting rod 290 are both connected with a handle 291 for holding.

The above design improves the convenience for operators when rotating the threaded rod 230 and the connecting rod 290 .

The two sets of support frames 120 are both provided with mounting holes 121 inside, and the connecting member 220 and the mounting block 250 are both provided with threaded holes 122 matching the mounting holes 121 on the top.

Through the above design, the support frame 120 can be easily installed and disassembled, so that the support frame 120 can be easily replaced.

The bottom inner walls of the first chamber 210 and the second chamber 240 are both provided with second slide grooves 292 , and the second slide grooves 292 are both slidably connected with second sliders 293 . The tops of the two sets of second sliders 293 are respectively connected to the connecting member 220 and the transmission block 260 .

Through the above design, the stability of the connecting member 220 and the transmission block 260 when moving left and right is improved.

The lower side of the mounting block 250 and the upper side of the transmission block 260 are arranged in an inclined shape that matches each other.

Through the above design, when the transmission block 260 moves to the left, it can push the installation block 250 to move upward.

A first sliding groove 251 is formed on the lower surface of the mounting block 250 , and a first sliding block 252 is slidably connected inside the first sliding groove 251 . One end of the first sliding block 252 away from the first sliding groove 251 is connected to the transmission block 260 .

Through the above design, when the transmission block 260 moves to the right, it can drive the installation block 250 to move downward, thereby preventing the installation block 250 and the transmission block 260 from being separated.

A lower notch 123 is formed in the middle of the upper portion of the support frame 120 , and upper notches 124 matching the shape of the upper portion of the support frame 120 are formed at the front and rear sides of the lower portion of the upper clamp ring 130 .

Through the above design, when the support frame 120 and the upper clamp ring 130 are installed, the semicircle above the support frame 120 and the semicircle above the upper clamp ring 130 can overlap, so that the space between the support frame 120 and the upper clamp ring 130 is not limited to a complete circle, which increases the vertical pressure of the sight after installation and increases the stability of the sight after installation.

In summary, the working principle of the present invention is: when the front support frame 120 needs to be adjusted to move left and right, the threaded rod 230 is rotated, and the threaded connection between the threaded rod 230 and the connecting member 220 can drive the connecting member 220 to move left and right;

When the height of the rear support frame 120 needs to be adjusted, the connecting rod 290 is rotated to drive the bolt block 280 to rotate. Through the threaded connection between the bolt block 280 and the thread groove 270, the transmission block 260 can be driven to move left and right. Through the squeezing and pulling of the installation block 250 by the transmission block 260, the installation block 250 can be adjusted up and down.

It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
