Description

Technical Field

[0001] The utility model relates to the technical field of sights, in particular to a prism group supporting component of a sight and the sight. Background Art

[0002] At present, prism sights usually use the swinging of the ball head prism group support component to achieve ballistic and wind direction adjustment. The prism group support component includes a lens body, a ball head prism bracket, a ball socket pressure ring and a limit screw. A ball socket is provided in the lens body. The ball head prism bracket is placed in the lens body and the front part of the ball head prism bracket is placed in the ball socket. The ball socket pressure ring is then installed in the lens body through a threaded connection. The rear part of the ball head prism bracket is placed in the ball socket pressure ring. In this way, the ball head prism bracket will not move forward and backward but can swing stably. A limit groove is provided on the ball head prism bracket. The limit groove extends along the axial direction of the prism bracket. The limit screw is fixed on the lens body and in the limit groove. In this way, the prism bracket can be prevented from deflecting around the axis of the lens body.

[0003] The prism group is installed in the ball head prism bracket. The prism group includes a half pentaprism and a roof prism, and a part of the half pentaprism and the roof prism exceeds the spherical surface where the ball head prism bracket is located, and a part of the ball socket pressure ring extends axially to the same axial position as the half pentaprism and the roof prism.

[0004] When the scope is vibrated by the impact of shooting, the ball-and-socket pressure ring will rotate around the axis of the scope body. Only when the outer diameter of the ball-and-socket pressure ring is larger than the outer dimensions of the semi-penta prism and the roof prism will the ball-and-socket pressure ring avoid colliding with the prism. However, this will make the scope bulky.

[0005] Consumers prefer smaller scopes, so when the ball-and-socket pressure ring is made smaller, the axis of the ball-and-socket pressure ring will deflect under the vibration of shooting and come into contact with the prism, causing scratches on the prism and even shadows in the field of view, which greatly affects usage. Utility Model Content

[0006] The first purpose of the utility model is to provide a prism group support component of a sighting scope which is advantageous for small volume design and solves the problem of prism scratches.

[0007] The second purpose of the utility model is to provide a sighting scope which is advantageous for small volume design and solves the problem of prism scratching.

[0008] The first purpose of the utility model provides a prism group support component of the sighting scope, which includes a scope body, a prism bracket and a ball socket pressure ring. A ball socket is arranged in the scope body, and the prism bracket and the ball socket pressure ring are both placed in the scope body. The ball socket and the ball socket pressure ring are arranged opposite to each other in the axial direction of the scope body, and the prism bracket is restricted between the ball socket and the ball socket pressure ring; the prism group support component of the sighting scope also includes a second limiting member and a second pressure ring; a limiting structure is arranged on the outer periphery of the ball socket pressure ring, and the second limiting member is connected to the inner wall surface of the scope body, and the second limiting member cooperates with the limiting structure to prevent the ball socket pressure ring from rotating around the axis of the scope body; the second pressure ring is arranged in the scope body, and the prism bracket, the ball socket pressure ring and the second pressure ring are arranged in sequence along the axial direction, and the second pressure ring restricts the ball socket pressure ring from the axial direction.

[0009] As can be seen from the above scheme, the utility model mainly solves the problem of the original small-sized ball-and-socket pressure ring rotating along the axis and scratching the prism by adding a second pressure ring. Since the original ball-and-socket pressure ring is installed to the lens body through a thread, the ball-and-socket pressure ring needs rotational freedom, while the utility model connects the lens body with the added second pressure ring and limits the ball-and-socket pressure ring with the second pressure ring. In this way, the ball-and-socket pressure ring no longer needs to be provided with a thread and no longer needs rotational freedom. Therefore, the rotation of the ball-and-socket pressure ring is directly limited by the cooperation of the second limiter and the limit structure. Even if the sighting scope is subjected to an impact force to deflect the second pressure ring around the axis, the ball-and-socket pressure ring always maintains the current angle. Therefore, even a smaller ball-and-socket pressure ring will not scratch the prism. The prism group support assembly of the utility model is conducive to a small volume design and solves the problem of prism scratches.

[0010] A further solution is that the surface of the prism bracket includes a first spherical surface; the ball socket pressure ring is provided with a side wall, the side wall includes an inner side facing the axis of the ball socket pressure ring, the inner side is provided with a second spherical surface, and the second spherical surface cooperates with the first spherical surface; the limiting structure is provided on the side wall.

[0011] As can be seen from the above, the side wall extends in the axial direction and has a relatively large position. Setting a limiting structure on the side wall has better selection space and is easier to form and process.

[0012] A further solution is that the limiting structure includes a limiting opening, which extends axially and opens at the end of the side wall, the limiting opening passes through both sides of the thickness of the side wall, and the second limiting member is located in the limiting opening.

[0013] Another further solution is that the limiting structure includes a screw hole arranged on the side wall, and the second limiting member is a limiting screw, and the limiting screw is threadably matched with the screw hole.

[0014] It can be seen from the above that both of the above two settings can ensure the anti-rotation effect on the ball socket pressure ring. The setting method of the restriction port makes the assembly simple, and the setting method of the screw hole is more stable and reliable.

[0015] Another further solution is that the ball socket pressure ring includes two side walls arranged opposite to each other on its outer circumference, and a prism avoidance opening is arranged between the two side walls on the circumference of the ball socket pressure ring, the prism avoidance opening is opened along the axial direction, and the prism avoidance opening is passed through along the radial direction of the ball socket pressure ring.

[0016] It can be seen from the above that even if the ball socket pressure ring does not rotate, it is extended axially to a certain extent, and a prism avoidance is provided to avoid interference with the prism.

[0017] A further solution is that, in the circumferential direction of the ball socket pressure ring, the angle occupied by the ball socket pressure ring is greater than the angle occupied by the side wall.

[0018] As can be seen from the above, this arrangement can make the prism avoidance opening large enough and provide enough movable positions during the assembly and adjustment process, thereby avoiding scratches on the prism during rotation during the assembly and adjustment process.

[0019] Another further solution is that an external thread is provided on the outer periphery of the second pressure ring, and an internal thread is provided inside the mirror body, and the external thread cooperates with the internal thread.

[0020] As can be seen from the above, under this arrangement, the second pressure ring is easy to assemble and disassemble and its position is adjustable.

[0021] A further solution is that the second pressure ring includes a retaining ring arranged toward the ball socket pressure ring, and the ball socket pressure ring abuts against the retaining ring.

[0022] As can be seen from the above, the retaining ring has a larger surface area in the axial direction. This arrangement can ensure that the end face of the ball socket pressure ring and the surface of the retaining ring are firmly abutted together.

[0023] In addition, a further solution is that the prism group support assembly of the sight also includes a first limiting member, a limiting groove is set on the prism bracket, and the first limiting member is fixedly connected in the scope body and is located in the limiting groove.

[0024] The second object of the utility model provides a sighting scope comprising a prism group and a prism group supporting assembly. The prism group supporting assembly adopts the prism group supporting assembly of the above-mentioned sighting scope, and the prism group is arranged in a prism bracket.

[0025] It can be seen from the above scheme that since the original ball-and-socket pressure ring is installed to the scope body through threads, the ball-and-socket pressure ring needs rotational freedom, while the utility model connects the scope body with an additional second pressure ring and limits the ball-and-socket pressure ring with the second pressure ring. The ball-and-socket pressure ring no longer needs to be provided with threads, and no longer needs rotational freedom. Therefore, the rotation of the ball-and-socket pressure ring is directly limited by the cooperation of the second limiter and the limit structure. Even if the scope is subjected to impact force to deflect the second pressure ring around the axis, the ball-and-socket pressure ring always maintains the current angle, and even a smaller ball-and-socket pressure ring will not scratch the prism. The prism group support assembly of the utility model is conducive to small-volume design and solves the problem of prism scratches. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] First embodiment of the prism support assembly of the sight

[0031] See also Figure 1 The sight of this embodiment includes a prism group support assembly and a prism group 3. The prism group support assembly includes a lens body 1, a prism bracket 2, a ball and socket pressure ring 4, a second pressure ring 5, a first limit screw 61 and a second limit screw 62. The first limit screw 61 and the second limit screw 62 are respectively the first limit member and the second limit member of the utility model.

[0032] See also Figure 1 A ball socket 11 is provided in the mirror body 1.

[0033] Recombination Figure 2 and Figure 3 The interior of the prism bracket 2 is a mounting position, and the prism group 3 is fixedly mounted in the mounting position; the outer periphery of the prism bracket 2 has a spherical outer contour, and the prism bracket 2 includes a first spherical surface 22. The first spherical surface 22 is not a complete spherical surface, but along the axial direction of the lens body 1, the first spherical surface 22 at least includes a part facing forward and another part facing backward. The first spherical surface 22 is provided with a concave limiting groove 21 that passes through along a straight line, such as Figure 1 As shown, when the prism bracket 2 is in a certain state, the limiting groove 21 extends along the axial direction of the lens body 1.

[0034] The ball socket pressure ring 4 mainly includes an annular base 40 and two side walls 41 connected to the base 40. The base 40 surrounds the axis of the ball socket pressure ring 4 itself, and the two side walls 41 extend axially from one side of the base 40. The ball socket pressure ring 4 includes two side walls 41 arranged opposite to each other on its outer periphery. A second spherical surface 411 is arranged on the inner side of the side wall 41 away from the end of the base 40. The above-mentioned inner side refers to the side of the side wall 41 facing the axis of the ball socket pressure ring 4 itself. The two opposite second spherical surfaces 411 constitute a ball socket structure that can limit the prism bracket 2.

[0035] Furthermore, a limiting opening 412 is provided on the side wall 41 . The limiting opening 412 is a limiting structure of the present invention. The limiting opening 412 extends axially and opens at the end of the side wall 41 . The limiting opening 412 passes through both sides of the thickness of the side wall 41 .

[0036] In addition, a prism avoidance opening 42 is provided between two side walls 41 on the circumference of the ball socket pressing ring 4, so that the two prism avoidance openings 42 are provided opposite to each other on the outer circumference of the ball socket pressing ring 4. Moreover, the prism avoidance opening 42 is opened along the axial direction, and the prism avoidance opening 42 is passed through along the radial direction of the ball socket pressing ring 4. On the other hand, on the circumference of the ball socket pressing ring 4, the angle occupied by the ball socket pressing ring 4 is greater than the angle occupied by the side wall 41.

[0037] An external thread 59 is arranged on the outer periphery of the second pressing ring 5 , and a retaining ring 51 is also arranged on one axial end of the second pressing ring 5 .

[0038] See also Figure 1 The prism holder 2, the ball socket pressure ring 4 and the second pressure ring 5 are all installed in the lens body 1 and abutted in sequence along the axial direction of the lens body 1. The ball socket 11 and the ball socket pressure ring 4 are arranged opposite to each other in the axial direction of the lens body 1. The front part of the first spherical surface 22 of the prism holder 2 cooperates with the ball socket 11, and the rear part of the first spherical surface 22 of the prism holder 2 cooperates with the second spherical surface 411 on the side walls 41 of the ball socket pressure ring 4. In this way, the prism holder 2 is restricted between the ball socket 11 and the ball socket pressure ring 4 in the axial direction, but the prism holder 2 has the degree of freedom of rotation.

[0039] The first limit screw 61 and the second limit screw 62 are both fixed by tightening corresponding screw holes from the outer periphery of the lens body 1, and the first limit screw 61 and the second limit screw 62 are both extended from the inner wall surface of the lens body 1 toward the inner space of the lens body 1. The first limit screw 61 extends into the limit groove 21 of the prism bracket 2, thereby preventing the prism bracket 2 from rotating around the axis of the lens body 1, and the second limit screw 62 is inserted into the limit opening 412 located on the side wall 41, thereby preventing the ball socket pressing ring 4 from rotating around the axis of the lens body 1.

[0040] The external thread 59 of the second pressing ring 5 and the internal thread 19 of the lens body 1 can make the retaining ring 51 on the second pressing ring 5 facing the ball socket pressing ring 4 abut against the base 40 of the ball socket pressing ring 4 by tightening the second pressing ring 5, thus producing a clamping effect.

[0041] Mainly, the utility model adds a second pressing ring 5 to solve the problem that the original small-sized ball-and-socket pressing ring 4 can rotate along the axis and scratch the prism group 3. Since the original ball-and-socket pressing ring 4 is installed to the lens body 1 through a thread, the ball-and-socket pressing ring 4 needs to rotate freely and can rotate, which may scratch the prism group 3. However, the utility model connects the lens body 1 with the added second pressing ring 5 and restricts the ball-and-socket pressing ring 4 with the second pressing ring 5. In this way, the ball-and-socket pressing ring 4 no longer needs to be provided with a thread or a rotational freedom, and the rotation of the ball-and-socket pressing ring 4 is directly restricted by the cooperation of the second limiting screw 62 and the limiting opening 412. Even if the sight is subjected to an impact force to deflect the second pressing ring 5 around the axis, the ball-and-socket pressing ring 4 always maintains the current angle. Therefore, even a smaller ball-and-socket pressing ring 4 will not scratch the prism. The prism group support assembly of the utility model is conducive to a small volume design and solves the problem of prism scratches.

[0042] Second embodiment of the prism support assembly of the sight

[0043] See also Figure 4 In this embodiment, the limiting structure is a screw hole 7412 provided on the side wall 741 , and the second limiting member is a limiting screw 762 , which is threadably matched with the screw hole 7412 .

[0044] In addition, the second pressing ring 75 in this embodiment is set shorter.

[0045] Since the ball socket pressure ring no longer needs to be provided with a threaded ring, the structure becomes shorter, and the second pressure ring can also be set shorter. In this way, the addition of the second pressure ring will not particularly affect the overall length of the sight.

[0046] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
