[0001] This application claims priority to Chinese Patent Application No. 202510060562.3, filed on January 15, 2025, entitled "An Optical Axis Adjustment Device"; Chinese Patent Application No. 202520088715.0, filed on January 15, 2025, entitled "An Optical Axis Adjustment Device"; and Chinese Patent Application No. 202520088709.5, filed on January 15, 2025, entitled "An Adjustment Module and Outdoor Aiming Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the fields of instrument measurement and calibration, and outdoor aiming technology, and further to an optical axis adjustment device, adjustment module, and outdoor aiming device. Background Technology

[0003] Rangefinders can be used alone or mounted on firearms. When used with firearms, the user needs to know the specific target being measured by the rangefinder. When there are multiple targets closely arranged in front, confusion can easily occur. Therefore, rangefinders are often used in conjunction with scopes. By observing the reticle in the scope window, the target being measured by the rangefinder can be clearly identified.

[0004] Due to assembly errors and installation gaps between the rangefinder and the scope, the optical axis of the rangefinder must be aligned parallel to the optical axis of the scope before use. Only after this alignment can the target be determined through the scope. A common method is to use the scope as a reference, adjust the optical axis of the rangefinder, and measure the distance between the rangefinder's light output position and the scope's optical axis during installation. At a certain distance, adjust the rangefinder's optical axis to the same distance from the scope's aiming point. This ensures the optical axes are parallel, and the rangefinder's optical axis is now coaxial with the accompanying visible laser. The measurement position can then be confirmed using the visible laser.

[0005] The principle of adjusting the optical axis of a rangefinder is as follows: Inside the rangefinder, the front end of the ranging component uses a fixed point as a fulcrum. During adjustment, by moving the rear end of the ranging component up, down, left, and right, the optical axis of the ranging component can swing around the fixed point. Within this swing range, it should be parallel to the optical axis of the scope. The industry commonly uses a ball joint structure as the fulcrum. This involves machining the front end of the ranging component into a ball joint, the size of which must encompass the entire ranging component. After the ball joint is fixed by other structures, it can only swing along its center, thus achieving the adjustment purpose. Ball joint structures are often used in cylindrical products like scopes. However, for non-cylindrical products like rangefinders, using a ball joint structure would significantly increase the product's dimensions, hindering structural design and resulting in considerable space waste.

[0006] Outdoor sights typically utilize windage and pitch adjustment functions. When in use, the relative position of the modules is adjusted to adjust the sight's front sight, compensating for and correcting deviations caused by external wind direction and gravity, thereby improving shooting accuracy.

[0007] The outdoor sight is equipped with two adjustment modules, allowing the rotating part to rotate and adjust around two axes. Currently available adjustment modules, when making an absolute adjustment, cause the rotating part in the middle of the module to move with the adjustment action. When the adjustment module pushes the optical axis to its limit, it completely blocks the rotating part against other structural components, which affects the adjustment in the other direction.

[0008] For those skilled in the art, how to reduce the volume of the adjustment structure and avoid interference between the two dimensions of adjustment is a technical problem that needs to be solved. Summary of the Invention

[0045] This invention provides an optical axis adjustment device. A bracket is used to mount a ranging module. The bracket is mounted on a housing via a rotation adjustment mechanism. A bushing of the rotation adjustment mechanism is mounted on the housing, and a rotating pin is mounted on the bracket. A rotating frame rotatably connects the bushing and the rotating pin. Therefore, the bracket rotates around a first rotation axis through the cooperation of the bushing and the rotating frame, and around a second rotation axis through the cooperation of the rotating frame and the rotating pin, allowing the bracket to rotate around both axes. A first rotation adjustment member can move closer to or further away from the bracket to push the bracket to rotate around the first rotation axis. A second rotation adjustment member can also move closer to or further away from the bracket to push the bracket to rotate around the second rotation axis. When the first and second rotation adjustment members are close to the bracket, a pushing force is generated; when they are far from the bracket, an elastic member provides a spring force to the bracket, causing the bracket to rotate in the opposite direction. Compared to a ball joint structure, this device reduces the overall volume.

[0046] This application provides an adjustment module, in which a support body is fixedly assembled to a support structure, and a rotary adjustment pin is rotatably assembled to the support body around a first axis. When the rotary adjustment pin rotates, it can drive a top pressure limiting slider to translate along the first axis through threaded transmission. The top pressure limiting slider includes a sliding column and a limiting block. The limiting block protrudes perpendicularly to the first axis and is disposed on the side wall of the sliding column. When the top pressure limiting slider extends to its maximum position, the limiting block can be blocked by the support body, thereby limiting the maximum extension position of the sliding column. Therefore, when adjusting two dimensions, when the top pressure limiting slider is adjusted to its maximum extension position, the rotating part will not be blocked, thus preventing interference between the two dimension adjustments.

Detailed Implementation

[0059] To enable those skilled in the art to better understand the technical solution of the present invention, the optical axis adjustment device of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] Referring to Figures 1 and 2, the present invention provides an optical axis adjustment device, including a housing 1, a bracket 2, a rotation adjustment mechanism 3, an elastic element 4, a first rotation adjustment element 5, a second rotation adjustment element 6, etc., wherein the housing 1 serves as the assembly base, and the other structures are mounted on the housing 1. The bracket 2 is used to mount devices such as a ranging module 7, and the bracket 2 can drive the mounted devices to rotate relative to the housing 1.

[0061] The rotation adjustment mechanism 3 includes a bushing 31, a rotating frame 32, and a rotating pin 33. The bushing 31 is installed on the outer casing 1, and the rotating pin 33 is installed on the bracket 2. The rotating frame 32 rotatably connects the bushing 31 and the rotating pin 33. The bracket 2 rotates around a first rotation axis through the cooperation of the bushing 31 and the rotating frame 32, and rotates around a second rotation axis through the cooperation of the rotating frame 32 and the rotating pin 33. As shown in Figure 3, Ⅰ represents the first rotation axis, which is horizontal; Ⅱ represents the second rotation axis, which is vertical. The first and second rotation axes are perpendicular to each other. The rotating frame 32 is inserted into the bushing 31 and can rotate relative to the bushing 31; the rotating pin 33 is inserted into the rotating frame 32 and can rotate relative to the rotating frame 32.

[0062] The elastic element 4 is disposed between the outer shell 1 and the bracket 2 to provide elastic force to the bracket 2. With the help of the elastic force of the elastic element 4, the bracket 2 is always in contact with the first rotation adjustment element 5 and the second rotation adjustment element 6.

[0063] The first rotation adjustment member 5 is installed on the outer casing 1. The movable part of the first rotation adjustment member 5 can approach or move away from the bracket 2, and is used to push the bracket 2 to rotate around the first rotation axis. The second rotation adjustment member 6 is installed on the outer casing 1. The movable part of the second rotation adjustment member 6 can approach or move away from the bracket 2, and is used to push the bracket 2 to rotate around the second rotation axis. As shown in Figure 4, the first rotation adjustment member 5 is used to generate a thrust on the bracket 2 in the horizontal direction, and the second rotation adjustment member 6 is used to generate a thrust on the bracket 2 in the vertical direction. When the first rotation adjustment member 5 approaches the bracket 2, it generates a thrust on the bracket 2, and the bracket 2 rotates around the first rotation axis. When the first rotation adjustment member 5 moves away from the bracket 2, the elastic member 4 generates a thrust on the bracket 2, causing the bracket 2 to rotate in the opposite direction around the first rotation axis, and the bracket 2 is always in contact with the movable part of the first rotation adjustment member 5. When the second rotation adjustment member 6 approaches the bracket 2, it generates a thrust on the bracket 2, and the bracket 2 rotates around the second rotation axis. When the second rotation adjustment member 6 moves away from the bracket 2, the elastic member 4 generates a thrust on the bracket 2, causing the bracket 2 to rotate in the opposite direction around the second rotation axis, and the bracket 2 is always in contact with the movable part of the second rotation adjustment member 6.

[0064] This invention enables the housing 1 and the support 2 to rotate and adjust around two axes via a rotation adjustment mechanism 3. The bushing 31 and the rotating frame 32 are hinged together, and the rotating frame 32 and the rotating pin 33 are also hinged together. Utilizing these two hinged connections, the support 2 can be adjusted to rotate around the first and second rotation axes respectively. Through the cooperation of the first rotation adjustment member 5, the second rotation adjustment member 6, and the elastic member 4, the angle of the support 2 can be adjusted by actively turning the movable parts of the first and second rotation adjustment members 5 and 6.

[0065] The optical axis adjustment device of the present invention forms a hinged fit in two positions through the three structures of the rotation adjustment mechanism 3. The bushing 31 and the rotating frame 32 form a hinged fit, and the rotating frame 32 and the rotating pin 33 form a hinged fit. Compared with the traditional complete ball joint structure, this device can reduce the overall volume and contribute to the miniaturization design of the entire optical axis adjustment device.

[0066] A support pin 11 is provided on the bottom surface of the outer casing 1. The top of the support pin 11 is a spherical surface for supporting the bracket 2. Regardless of the position of the bracket 2, the spherical structure of the support pin 11 always contacts the bracket 2, thereby supporting the bracket 2 and keeping it stable during adjustment to prevent it from shaking. The support pin 11 should be located at two opposite apex corners of the elastic element 4 to balance the elastic force formed by the elastic element 4 and prevent the corners of the bracket 2 from tilting up. When the bracket 2 rotates around the second rotation axis, the spherical surface of the support pin 11 can always contact and support the bracket 2.

[0067] It should be noted that the support pin 11 can also be set on the bracket 2. In this case, the part of the support pin 11 that contacts the outer shell 1 is set as a spherical surface, which can also play a supporting role.

[0068] As shown in Figure 4, the bracket 2 is provided with an insertion slot 21 and an installation slot 22 along the second rotation axis. The insertion slot 21 and the installation slot 22 are coaxially arranged, and a channel for installing the fastening screw 23 is provided between the insertion slot 21 and the installation slot 22. The rotating pin 33 is inserted into the insertion slot 21 of the bracket 2 along the second rotation axis and passes through the rotating frame 32. The installation slot 22 is used for installing the fastening screw 23 and is threadedly connected to the rotating pin 33. When the rotating pin 33 is locked to the bracket 2 by the fastening screw 23, the rotating pin 33 cannot be translated along the second rotation axis.

[0069] As shown in Figure 4, a sliding plate 24 is installed on the bracket 2. The sliding plate 24 is made of wear-resistant material and is used to contact the spherical surface at the top of the support pin 11, thereby preventing the support pin 11 from causing wear to the bracket 2.

[0070] Specifically, referring to Figure 5, the bushing 31 in this invention is a bearing. The rotating shaft of the rotating frame 32 is inserted into the inner ring of the bearing and fixed by screws. The screws are inserted into the rotating shaft and form a threaded fit, thus fixing the rotating frame 32 and the inner ring of the bearing. The rotating pin 33 is a cylindrical pin, inserted into the rotation channel of the rotating frame 32. Lubricating grease is applied between the rotating pin 33 and the rotation channel of the rotating frame 32 to reduce friction. The bushing 31 uses a bearing while the rotating pin 33 is directly slidably assembled with the rotating frame 32, which helps to reduce the dimension in the vertical height direction.

[0071] As shown in Figure 4, the present invention includes one elastic element 4, which is a helical spring used to apply an inclined elastic force to the bracket 2. The elastic force of the elastic element 4 has components on both the first and second rotation axes. The elastic force applied by the elastic element 4 to the bracket 2 is neither parallel to the first rotation axis nor parallel to the second rotation axis. The inclined elastic element 4 can resist the thrust of both the first rotation adjustment element 5 and the second rotation adjustment element 6.

[0072] A support block 25 is provided on the bracket 2. The support block 25 adopts a detachable connection method, which is convenient for processing and easy to replace. The support block 25 has at least two mutually perpendicular sides. The first rotation adjustment member 5 and the second rotation adjustment member 6 press against the two sides of the support block 25 respectively. The pressure direction of the first rotation adjustment member 5 and the pressure direction of the second rotation adjustment member 6 are used to resist the elastic force of the elastic member 4. As shown in Figure 2, the support block 25 and the elastic member 4 are located on the same side of the vertical plane passing through the second rotation axis. The pushing force of the first rotation adjustment member 5 and the second rotation adjustment member 6 on the support block 25 can compress the elastic member 4.

[0073] As shown in Figure 4, the present invention provides a mounting boss 12 on the bottom plate of the outer shell 1. The thickness of the mounting boss 12 is greater than the thickness of other parts of the bottom plate. The bushing 31 is installed in the assembly groove 121 of the mounting boss 12. The thickness of the mounting boss 12 is greater than the height of the bushing 31, and the height of the assembly groove 121 is greater than the height of the bushing 31, ensuring that there is sufficient overlap area between the bushing 31 and the assembly groove 121, thus providing sufficient restraint for the bushing 31 and preventing the bushing 31 from tilting.

[0074] To improve the sealing effect, the present invention connects the sealing cover 13 to the inner thread of the assembly groove 121 and applies sealant. The sealing cover 13 is used to cover the sealing rotation adjustment mechanism 3, reduce the entry of external dust and impurities into the rotation adjustment mechanism 3, and ensure the long-term stable use of the rotation adjustment mechanism 3.

[0075] Referring to Figures 1 and 3, a visible laser module 8 is mounted on the bracket 2. One end of the visible laser module 8 has an end spherical surface 81, which mates with the mounting bracket 26 on the bracket 2. This spherical fit allows adjustment of the emission angle of the visible laser module 8, ensuring that the visible laser emitted by the module 8 remains parallel to the ranging laser of the ranging module 7. The laser of the ranging module 7 is invisible; its position can be determined by the indicator point on the visible laser module 8.

[0076] The optical axis adjustment device of the present invention uses the bracket 2 as a reference, which can realize the free adjustment of the optical axis within a certain range of up, down, left and right. It has high structural reliability, and the optical axis will not be affected by external impact and vibration after it is fixed. It has a compact structure, is easy to adjust, and effectively improves shooting accuracy.

[0077] Referring to Figures 6 and 7, this application provides an adjustment module, which is the second rotation adjustment component 6 mentioned above. It includes a support body 6.1, a rotation adjustment pin 6.2, a top pressure limiting slider 6.3, and other structures. The support body 6.1 is fixedly assembled to the support structure, which can be a structure such as the shell of an outdoor sight. The support body 6.1 is the main body of the entire adjustment module, and other components are installed on the support body 6.1.

[0078] The rotating adjusting pin 6.2 is rotatably assembled on the support body 6.1 around the first axis, as shown in Figure 7, where the dashed line A represents the first axis. The rotating adjusting pin 6.2 can rotate around the first axis, but it cannot translate along the first axis; it can only rotate.

[0079] The top-pressure limiting slider 6.3 includes a sliding post 6.31 and a limiting block 6.32. The limiting block 6.32 protrudes perpendicularly to the first axis and is disposed on the side wall of the sliding post 6.31. As shown in Figure 7, the limiting block 6.32 protrudes from the side wall of the sliding post 6.31, and the entire top-pressure limiting slider 6.3 forms a widened portion at the limiting block 6.32, which serves as a limiting and stopping mechanism.

[0080] The sliding column 6.31 is slidably assembled to the support body 6.1 along the first axis. The sliding column 6.31 can translate relative to the support body 6.1 along the first axis, but the top-pressing limiting slider 6.3 cannot rotate relative to the support body 6.1; the top-pressing limiting slider 6.3 can only translate. The sliding column 6.31 is a columnar structure with the same cross-sectional shape (perpendicular to the first axis). One end of the sliding column 6.31 can extend beyond the support body 6.1. The sliding column 6.31 and the support body 6.1 are in sliding contact. The support body 6.1 is provided with a channel slightly larger than the sliding column 6.31. The sliding channel on the support body 6.1 has a certain contact area with the outer wall of the support body 6.1, which can guide the sliding column 6.31 to make linear translational movements.

[0081] The external thread of the rotary adjusting pin 6.2 and the internal thread of the top pressure limiting slider 6.3 form a threaded connection. The rotation of the rotary adjusting pin 6.2 drives the top pressure limiting slider 6.3 to translate, thereby adjusting the length of the end of the sliding column 6.31 extending beyond the support body 6.1. The limiting block 6.32 can be blocked by the support body 6.1, thus limiting the maximum extension position of the sliding column 6.31, allowing the top pressure limiting slider 6.3 to move telescopically within a certain range. When the top pressure limiting slider 6.3 reaches its maximum extension position, it will not detach from the support body 6.1. The maximum extension position of the top pressure limiting slider 6.3 is limited by the support body 6.1 of the adjusting module itself and does not rely on other external structures for limitation.

[0082] When the adjustment module of this application is applied to an outdoor sight, a pressing force can be applied to the rotating part, thereby enabling the rotating part to rotate. When the pressing limit slider 6.3 reaches the limit extension position, the rotating part is not yet locked, and the rotating part does not reach the housing or other positions of the adjustment module. Therefore, when the rotating part is pressed from another direction, it will not be hindered by friction.

[0083] Based on the above scheme, the support body 6.1 of this application includes a pressure ring 6.11 and an adjusting seat 6.12 that are assembled together. The pressure ring 6.11 and the adjusting seat 6.12 are two independent but interconnected structures that together constitute the support body 6.1. After the pressure ring 6.11 and the adjusting seat 6.12 are assembled and fixed, they do not need to move or rotate relative to each other, forming a relatively fixed relationship. As shown in Figure 7, the inner cavity of the pressure ring 6.11 has a receiving space, and the adjusting seat 6.12 is inserted into the pressure ring 6.11 along the first axis, with the pressure ring 6.11 fitted outside the adjusting seat 6.12.

[0084] When the pressure ring 6.11 and the adjusting seat 6.12 are assembled in place, the pressure ring 6.11 and the adjusting seat 6.12 respectively contact the rotating disk 6.21 set on the rotating adjusting pin 6.2 from both sides, thereby positioning the rotating adjusting pin 6.2 on the first axis. The rotating disk 6.21 is a boss structure protruding from the side wall of the rotating adjusting pin 6.2. The rotating disk 6.21 can be a complete circular ring structure or multiple independent protrusions located on the same circumference. As shown in Figure 7, the pressure ring 6.11 and the adjusting seat 6.12 are located on both sides of the rotating disk 6.21 on the first axis. The pressure ring 6.11 presses on the upper surface of the rotating disk 6.21, and the adjusting seat 6.12 presses on the lower surface of the rotating disk 6.21. The pressure ring 6.11 and the adjusting seat 6.12 cooperate to clamp the rotating disk 6.21. The pressure ring 6.11 and the adjusting seat 6.12 limit the rotation adjustment pin 6.2 on the first axis. Therefore, the rotation adjustment pin 6.2 can only rotate around the first axis and cannot translate along the first axis.

[0085] Referring to Figures 6 and 7, the adjusting seat 6.12 is a cylindrical structure with a base plate and side walls. The top of the adjusting seat 6.12 is not closed, allowing the top-pressing limiting slider 6.3 to be inserted from the top. The base plate of the adjusting seat 6.12 has a through-channel along the first axis for the sliding column 6.31 to pass through. This channel allows the sliding column 6.31 to pass through, but the limiting block 6.32 cannot. The limiting block 6.32 can press against the inner side of the base plate of the adjusting seat 6.12 (the upper surface of the base plate in Figure 7) for limiting. The cross-sectional area of ​​the inner cavity of the adjusting seat 6.12 is larger than the cross-sectional area of ​​the limiting block 6.32. There is a certain gap between the inner side wall of the adjusting seat 6.12 and the limiting block 6.32 to prevent friction against the side wall of the limiting block 6.32.

[0086] As shown in Figure 7, the rotary adjusting pin 6.2 includes a guide portion 6.22 and a drive portion 6.23, which are integrally formed to constitute the rotary adjusting pin 6.2. The cross-sectional area of ​​the guide portion 6.22 is larger than that of the drive portion 6.23, and the longitudinal cross-section of the rotary adjusting pin 6.2 is T-shaped. A rotating disk 6.21 is disposed on the outer periphery of the guide portion 6.22, and the height of the guide portion 6.22 is greater than the height of the rotating disk 6.21.

[0087] The outer side wall of the drive unit 6.23 is provided with an external thread, and the inner side wall of the top pressure limiting slider 6.3 is provided with an internal thread. The external thread of the drive unit 6.23 and the internal thread of the top pressure limiting slider 6.3 are engaged. When the rotating adjusting pin 6.2 rotates around the first axis, the top pressure limiting slider 6.3 can be translated along the first axis through the thread transmission. By controlling the rotation direction of the rotating adjusting pin 6.2 to rotate clockwise or counterclockwise, the top pressure limiting slider 6.3 can be translated upward or downward in the direction shown in Figure 7.

[0088] The top of the pressure limiting slider 6.3 can press against the bottom surface of the guide portion 6.22, thus limiting the maximum retraction position of the pressure limiting slider 6.3. Figure 7 shows the maximum outward extension position of the pressure limiting slider 6.3, and Figure 8 shows the maximum inward retraction position of the pressure limiting slider 6.3. When the pressure limiting slider 6.3 retracts to its maximum position, the limiting block 6.32 contacts the bottom surface of the guide portion 6.22, at which point the pressure limiting slider 6.3 cannot move further upward. Therefore, the pressure limiting slider 6.3 can only move up and down within the range between Figure 7 and Figure 8. The limiting block 6.32 in Figure 8 is located at the topmost point of the entire pressure limiting slider 6.3 so that it can contact the bottom surface of the guide portion 6.22. If the limiting block 6.32 is not at the topmost point, the limiting block 6.32 will not contact the bottom surface of the guide portion 6.22.

[0089] Referring to Figures 7 and 9, an installation channel 6.221 is provided perpendicular to the first axis on the guide portion 6.22. The installation channel 6.221 is a blind hole. A pin 6.24 and an elastic element 6.25 are installed in the installation channel 6.221. The elastic element 6.25 applies an outward elastic force to the pin 6.24, causing the pin 6.24 to tend to protrude from the guide portion 6.22. The inner wall of the adjusting seat 6.12 is provided with positioning teeth 6.121, which are arranged in a circle around the first axis, forming a circumferential undulating wave structure on the inner wall of the adjusting seat 6.12. The height of the pin 6.24 is directly opposite the positioning teeth 6.121. When the rotating adjusting pin 6.2 rotates, it drives the pin 6.24 to rotate synchronously. The pin 6.24 is used to engage with different positioning teeth 6.121. As shown in Figure 9, each positioning tooth 6.121 is a wave-shaped protrusion facing the first axis, forming a trough between two adjacent positioning teeth 6.121. The pin 6.24 is pressed inward by the positioning teeth 6.121, compressing the elastic element 6.25. When the pin 6.24 passes through the trough, it protrudes from the elastic element 6.25 and elongates. By setting the pin 6.24 and the elastic element 6.25, a "click" sound can be generated during rotation, providing feedback to the user. Furthermore, when the pin 6.24 is engaged in the trough, it provides a certain degree of self-locking.

[0090] As shown in Figures 7 and 8, the exposed surface of the guide portion 6.22 is flush with the supporting body 6.1, maintaining a flat appearance. The exposed surface of the guide portion 6.22 is provided with a turning groove 6.222 for turning, allowing the rotating adjusting pin 6.2 to be turned by inserting a flat object such as a coin. The turning groove 6.222 can be a straight groove, a cross-shaped groove, or other shaped slots. The design of the turning groove 6.222 prevents the rotating adjusting pin 6.2 from being turned by hand, thus preventing accidental operation.

[0091] As shown in Figure 7, a first sealing ring 6.13 is provided on the outer side of the pressure ring 6.11 to form a seal between the pressure ring 6.11 and the external support structure. A second sealing ring 6.14 and a third sealing ring 6.15 are provided between the pressure ring 6.11 and the adjusting seat 6.12 to form a seal using the gap between the pressure ring 6.11 and the adjusting seat 6.12.

[0092] One end of the adjusting seat 6.12 is provided with a limiting flange 6.122 for abutting and limiting the end of the pressure ring 6.11. As shown in Figure 7, the limiting flange 6.122 is provided at the bottom end of the adjusting seat 6.12, and the limiting flange 6.122 is a circumferential boss formed perpendicular to the first axis. The other end of the adjusting seat 6.12 is provided with a third annular groove for placing the third sealing ring 6.15. The rotating disk 6.21 compresses the third sealing ring 6.15. In Figure 7, the upper end of the side wall of the adjusting seat 6.12 is provided with a third annular groove. The third annular groove has no top surface. The third annular groove cooperates with the rotating disk 6.21 to compress the third sealing ring 6.15 from top to bottom.

[0093] The end of the pressure ring 6.11 is provided with a conical surface 6.111, as shown in Figure 7. The inner edge of the lower end of the pressure ring 6.11 is chamfered to form the conical surface 6.111. The outer surface of the side wall of the adjusting seat 6.12 is provided with a second annular groove for placing the second sealing ring 6.14. The bottom surface of the second annular groove is a limiting flange 6.122. The conical surface 6.111 and the limiting flange 6.122 cooperate to compress the second sealing ring 6.14 and form a sealing effect.

[0094] The end of the pressure ring 6.11 is provided with an outer flange 6.112. The outer surface of the side wall of the pressure ring 6.11 is provided with a first annular groove for the installation of the first sealing ring 6.13, as shown in Figure 7. The top surface of the first annular groove is the outer flange 6.112. When the pressure ring 6.11 is installed, a seal is formed between the outer flange 6.112 and the support structure.

[0095] As shown in Figure 10, the side wall of the sliding column 6.31 has two cutting surfaces 6.311, which are used to cooperate with the channel provided on the bottom plate of the adjusting seat 6.12 to prevent rotation. The cross-section of the sliding column 6.31 should not be cylindrical. Using a non-cylindrical structure can form a circumferential limit on the sliding column 6.31, preventing it from rotating and allowing only translational movement. The number of cutting surfaces 6.311 can be set as needed. The cutting surfaces 6.311 can be planar or non-planar, as long as the side wall of the sliding column 6.31 forms a non-cylindrical shape. Each cutting surface 6.311 corresponds to a limiting block 6.32. In the case shown in Figure 10, two limiting blocks 6.32 are set. The cutting surface 6.311 forms a dimensionally contracted part. The limiting blocks 6.32 at the cutting surface 6.311 prevent the width of the entire top-pressure limiting slider 6.3 from becoming too large.

[0096] The sliding post 6.31 has a spherical end for abutting. As shown in Figure 7, the lower end of the sliding post 6.31 is a closed structure, forming a spherical surface, which can contact the structure that needs to be abutted. The spherical surface can reduce the contact area of ​​abutting.

[0097] This application also provides an outdoor sight, the specific structure of which is not shown in the accompanying drawings. This outdoor sight includes the aforementioned adjustment modules. Two adjustment modules are provided on the outdoor sight, each abutting against a different position of the rotating part, for rotating the part around different axes. The two adjustment modules are used to adjust the position of the rotating part. When the top-pressing limit slider 6.3 of any one adjustment module reaches its maximum extended position, the rotating part is not locked, and the rotating part has not yet contacted the outer shell of the outdoor sight. Therefore, when the top-pressing limit slider 6.3 of the other adjustment module is pressed down for adjustment, the adjustment can be smooth and will not be difficult due to excessive friction.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
