Description

Technical Field

[0001] This utility model relates to the field of reticle structure technology, and in particular to a semi-pentagonal prism reticle structure. Background Technology

[0002] Half-pentagonal prisms and roof prisms are widely used as image-inverting optical elements in prism rifle sights. The production process of sights, especially the production of half-pentagonal prisms, has particularly stringent technical requirements, including the surface finish and angularity of the half-pentagonal prism. Even small errors can severely affect the quality of the finished sight. In current technology, the reticle is directly machined onto the half-pentagonal prism. During machining, a film, such as a chromium plating, aluminum plating, or silver plating, is first applied to the surface of the half-pentagonal prism.

[0003] The main existing methods for processing reticles are: (1) chemical etching, which uses chemical etching to engrave aiming lines on a half-pentagonal prism. This method requires the creation of many molds for each reticle, resulting in high production costs and long production cycles; (2) laser engraving, which uses ultraviolet light or a laser engraving machine to engrave reticles on the mirror surface of a half-pentagonal prism. This method does not require the creation of molds, but it is prone to processing errors, which are difficult to compensate for and may even lead to the scrapping of the entire half-pentagonal prism. In summary, regardless of whether it is chemical etching or laser engraving, the preparation period required for chemical etching, such as the production of a mask, is relatively long. Both methods directly process reticles on the half-pentagonal prism, inevitably leading to the scrapping of the half-pentagonal prism, and the cost of a single half-pentagonal prism is relatively high.

[0004] For example, the patent entitled "A Semi-Pentagonal Reticle Structure" (patent application number: CN201320330673.4) discloses a semi-pentagonal reticle structure that separates the reticle markings from the semi-pentagonal prism, avoiding repeated or multiple processing on the semi-pentagonal prism, ensuring the quality of the semi-pentagonal prism, and reducing production difficulty, thereby greatly improving production efficiency and meeting the development needs of large-scale production. However, in actual use, because the semi-pentagonal prism and the reticle are separate structures, gaps are easily formed due to vibration during use, affecting the efficiency of use.

[0005] Therefore, it is necessary to propose a semi-pentagonal prism reticle structure to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a semi-pentagonal prism reticle structure to solve the problem that, in actual use, gaps can easily appear due to vibration during use because the semi-pentagonal prism and the reticle are separate structures, thus affecting the efficiency of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a semi-pentagonal prism reticle structure, comprising a semi-pentagonal prism body, a fixing sleeve adhered to the semi-pentagonal prism body, a reticle body disposed inside the fixing sleeve and attached to the semi-pentagonal prism body, a positioning sleeve threadedly connected to the outside of the fixing sleeve, a rubber pad disposed inside the fixing sleeve, one end of the rubber pad abutting against the reticle body, the other end of the rubber pad abutting against the inner wall of the positioning sleeve, and the outer ring of the rubber pad being wavy.

[0008] Preferably, the reticle body is provided with reticle lines.

[0009] Preferably, the fixing sleeve has a first annular groove on the side facing the semi-pentagonal prism body.

[0010] Preferably, an adhesive layer is provided inside the first annular groove.

[0011] Preferably, a second annular groove is provided on the outer ring of the positioning sleeve, the second annular groove is distributed around the positioning sleeve, a rotating ring is rotatably connected inside the second annular groove, and a positioning component for preventing the positioning sleeve from reversing is provided between the rotating ring and the fixed sleeve.

[0012] Preferably, the positioning component includes a first support plate, a second support plate, and screws. The first support plate is fixedly connected to the outer ring of the fixing sleeve, and the second support plate is fixedly connected to the outer ring of the rotating ring. The first support plate and the second support plate are distributed correspondingly and are connected by screws.

[0013] Preferably, the positioning components are provided in multiple sets, and the multiple sets of positioning components are evenly distributed around the positioning sleeve.

[0014] Preferably, the positioning sleeve has a mounting groove at the end away from the semi-pentagonal prism body, and a backlight is provided inside the mounting groove and fixed on the positioning sleeve.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model, by setting up structures such as a fixing sleeve, a positioning sleeve, and a rubber pad, ensures that the reticle body is always in contact with the semi-pentagonal prism body. The fixing sleeve and the positioning sleeve are detachable structures, which facilitates the inspection and replacement of the reticle body and improves the utilization efficiency of the semi-pentagonal prism reticle structure.

[0025] This utility model provides, for example Figures 1-6 The illustrated semi-pentagonal prism reticle structure includes a semi-pentagonal prism body 1 and a fixing sleeve 2 bonded to the semi-pentagonal prism body 1. To improve the stability of the bonding between the fixing sleeve 2 and the semi-pentagonal prism body 1, a first annular groove 4 is provided on the side of the fixing sleeve 2 facing the semi-pentagonal prism body 1. An adhesive layer is provided inside the first annular groove 4. Before installation, glue is applied to the inside of the first annular groove 4 and then bonded to the semi-pentagonal prism body 1. The glue dries to form an adhesive layer. Since the adhesive layer has a certain thickness, the stability of the bonding can be improved.

[0026] The fixed sleeve 2 has a reticle body 5 inside, and the reticle body 5 is attached to the semi-pentagonal prism body 1. The reticle body 5 has reticle lines 14, which are used as aiming lines. Specifically, the reticle body 5 has a coating, and the reticle lines 14 are etched on the coating.

[0027] The fixed sleeve 2 is externally threaded with a positioning sleeve 3. The end of the positioning sleeve 3 away from the semi-pentagonal prism body 1 is provided with a mounting groove 12. A backlight 13 is provided inside the mounting groove 12 and the backlight 13 is fixed on the positioning sleeve 3.

[0028] The backlight 13 provides an illumination source and works in conjunction with the reticle body 5, the reticle 14 and the semi-pentagonal prism body 1 to improve the effect of the aiming reticle.

[0029] Furthermore, the fixing sleeve 2 and the positioning sleeve 3 are detachable structures, which facilitates the inspection, replacement and other operations of the reticle body 5.

[0030] In addition, a sliding groove or slider (not shown in the figure) can be provided between the reticle body 5 and the inner wall of the fixed sleeve 2 to prevent the reticle body 5 from rotating arbitrarily.

[0031] To ensure that the reticle body 5 always fits against the semi-pentagonal prism body 1, a rubber pad 6 is provided inside the fixing sleeve 2. One end of the rubber pad 6 abuts against the reticle body 5, and the other end of the rubber pad 6 abuts against the inner wall of the positioning sleeve 3. The outer ring of the rubber pad 6 is wavy.

[0032] When the positioning sleeve 3 is rotated, the rubber pad 6 is squeezed to avoid direct hard compression of the reticle body 5, so that the reticle body 5 always adheres to the semi-pentagonal prism body 1, and the rubber pad 6 will shrink, so the semi-pentagonal prism body 1 and the reticle body 5 will not separate due to shaking. Since the outer ring of the rubber pad 6 is wavy, the outer ring of the rubber pad 6 deforms more obviously, while the inner ring deforms less, reducing the impact on the backlight 13.

[0033] To prevent the positioning sleeve 3 from reversing, a second annular groove 7 is provided on the outer ring of the positioning sleeve 3. The second annular groove 7 is distributed around the positioning sleeve 3. A rotating ring 8 is rotatably connected inside the second annular groove 7. A positioning component for preventing the positioning sleeve 3 from reversing is provided between the rotating ring 8 and the fixed sleeve 2. Multiple sets of positioning components are provided, and the multiple sets of positioning components are evenly distributed around the positioning sleeve 3.

[0034] The positioning assembly includes a first support plate 9, a second support plate 10, and a screw 11. The first support plate 9 is fixedly connected to the outer ring of the fixing sleeve 2, and the second support plate 10 is fixedly connected to the outer ring of the rotating ring 8. The first support plate 9 and the second support plate 10 are distributed accordingly and are connected by the screw 11.

[0035] In actual use, the positioning sleeve 3 is installed on the fixed sleeve 2, and the rotating ring 8 is rotated so that the first support plate 9 and the second support plate 10 are distributed accordingly. Then, the first support plate 9 and the second support plate 10 are connected with screws 11 to improve the stability of the connection between the positioning sleeve 3 and the fixed sleeve 2, so that the scoring reticle body 5 is always in contact with the semi-pentagonal prism body 1.
