Description

Technical Field

[0001] This utility model relates to the field of outdoor aiming, and more specifically to an adjustment module and an outdoor aiming device. Background Technology

[0002] 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.

[0003] 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.

[0004] How to avoid interference between the two dimensions of adjustment is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The core of this utility model is to provide an adjustment module in which the maximum extension position of the top pressure limiting slider is limited by the supporting body, which can prevent one dimension from being blocked when adjusting two dimensions and avoid interference between the adjustments of the two dimensions. The specific solution is as follows:

[0008] A rotary adjustment pin is mounted on the support body and rotates around a first axis.

[0009] 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. The sliding column is slidably assembled to the support body along the first axis. The external thread of the rotary adjusting pin is threadedly connected to the internal thread of the top-pressure limiting slider. The rotation of the rotary adjusting pin is used to drive the top-pressure limiting slider to translate, so as to adjust the length of the end of the sliding column extending out of the support body. The limiting block can be blocked by the support body, thereby limiting the maximum extension position of the sliding column.

[0010] Optionally, the support body includes a pressure ring and an adjusting seat that are assembled together, with the adjusting seat inserted into the pressure ring along the first axis; the pressure ring and the adjusting seat respectively contact the rotating disk on which the rotating adjusting pin is disposed from both sides, thereby limiting the rotating adjusting pin on the first axis.

[0011] Optionally, the base plate of the adjusting seat is provided with a channel through which the sliding column passes along the first axis, and the limiting block can press against the inner side of the base plate of the adjusting seat to limit its movement.

[0012] Optionally, the rotating adjusting pin includes a guide portion and a driving portion, and the rotating disk is disposed on the outer periphery of the guide portion; the cross-section of the guide portion is larger than the cross-sectional area of ​​the driving portion, and the external thread of the driving portion engages with the internal thread of the top pressure limiting slider; the top end of the top pressure limiting slider can press against the bottom surface of the guide portion to limit the maximum retraction position of the top pressure limiting slider.

[0013] Optionally, the guide portion is provided with an installation channel perpendicular to the first axis, and a pin and an elastic element are installed in the installation channel. The elastic element applies an outward extending elastic force to the pin.

[0014] The inner wall of the adjusting seat is provided with positioning teeth, and when the rotating adjusting pin rotates, the pin is used to engage with different positioning teeth.

[0015] Optionally, the exposed surface of the guide portion is flush with the support body, and the exposed surface of the guide portion is provided with a turning groove for turning.

[0016] Optionally, a first sealing ring is provided on the outer side of the pressure ring;

[0017] A second sealing ring and a third sealing ring are provided between the pressure ring and the adjusting seat.

[0018] Optionally, a limiting flange is provided at one end of the adjusting seat for abutting and limiting the end of the pressure ring; a third annular groove is provided at the other end of the adjusting seat for placing the third sealing ring, and the rotating disk compresses the third sealing ring;

[0019] The end of the pressure ring is provided with a conical surface, and the outer surface of the side wall of the adjusting seat is provided with a second annular groove for placing the second sealing ring. The conical surface and the limiting flange cooperate to compress the second sealing ring.

[0020] The pressure ring has an outer flange at its end, and a first annular groove for installing the first sealing ring is provided on the outer surface of the side wall of the pressure ring.

[0021] Optionally, the side wall of the sliding column is provided with two cutting surfaces to cooperate with the channel provided on the bottom plate of the adjusting seat to prevent rotation; each cutting surface is provided with a limiting block.

[0022] And / or, the end of the sliding post used for abutment is configured as a spherical surface.

[0023] This utility model also provides an outdoor aiming device, including any of the above-mentioned adjustment modules, the two adjustment modules being used to adjust the position of the rotating part, and when the top-pressing limit slider reaches the maximum extension position, the rotating part is not locked.

[0024] This utility model provides an adjustment module. A support body is fixedly assembled to a support structure, and a rotating adjustment pin is rotatably assembled to the support body around a first axis. When the rotating adjustment pin rotates, it can drive the 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

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the adjustment module and outdoor aiming device of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Combination Figure 1 , Figure 2 As shown, this utility model provides an adjustment module, including a support body 1, a rotating adjustment pin 2, a top pressure limiting slider 3, etc., wherein the support body 1 is fixedly assembled to the support structure, and the support structure can be the shell of an outdoor sight, etc.; the support body 1 is the main body of the entire adjustment module, and other components are installed on the support body 1.

[0035] The rotating adjusting pin 2 is mounted on the support body 1 and rotates around the first axis. Figure 2 As shown, the dashed line A represents the first axis. The rotary adjustment pin 2 can rotate around the first axis. The rotary adjustment pin 2 cannot translate along the first axis; the rotary adjustment pin 2 can only rotate.

[0036] The top-pressure limiting slider 3 includes a sliding post 31 and a limiting block 32. The limiting block 32 protrudes perpendicularly to the first axis and is disposed on the side wall of the sliding post 31, in conjunction with... Figure 2 As shown, the limiting block 32 protrudes from the side wall of the sliding column 31, and the entire top-pressing limiting slider 3 forms a widened part at the limiting block 32, which plays the role of limiting and stopping.

[0037] The sliding column 31 is slidably assembled to the support body 1 along the first axis. The sliding column 31 can translate relative to the support body 1 along the first axis, but the top-pressing limiting slider 3 cannot rotate relative to the support body 1; the top-pressing limiting slider 3 can only translate. The sliding column 31 is a columnar structure with the same cross-sectional shape (perpendicular to the first axis). One end of the sliding column 31 can extend beyond the support body 1. The sliding column 31 slides in contact with the support body 1. The support body 1 has a channel slightly larger than the sliding column 31. The sliding channel on the support body 1 has a certain contact area with the outer wall of the support body 1, which can guide the sliding column 31 to make linear translational movements.

[0038] The external thread of the rotary adjusting pin 2 and the internal thread of the top pressure limiting slider 3 form a threaded connection. The rotation of the rotary adjusting pin 2 drives the top pressure limiting slider 3 to translate, thereby adjusting the length of the end of the sliding column 31 extending beyond the support body 1. The limiting block 32 can be blocked by the support body 1, thereby limiting the maximum extension position of the sliding column 31, allowing the top pressure limiting slider 3 to move telescopically within a certain range. When the top pressure limiting slider 3 reaches the maximum extension position, the top pressure limiting slider 3 will not detach from the support body 1. The maximum extension position of the top pressure limiting slider 3 is limited by the support body 1 of the adjusting module itself, and does not rely on other external structures for limitation.

[0039] When the adjustment module of this utility model 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 3 reaches the limit extension position, the rotating part is not yet locked, and the rotating part does not reach the outer shell of the adjustment module or other positions. Therefore, when the rotating part is pressed from another direction, it will not be hindered by friction.

[0040] Based on the above scheme, the support body 1 of this utility model includes a pressure ring 11 and an adjusting seat 12 assembled together. The pressure ring 11 and the adjusting seat 12 are two independent but interconnected structures, which together constitute the support body 1. After the pressure ring 11 and the adjusting seat 12 are assembled and fixed, they do not need to move or rotate relative to each other, forming a relatively fixed relationship. Figure 2 As shown, the inner cavity of the pressure ring 11 has a receiving space, and the adjusting seat 12 is inserted into the pressure ring 11 along the first axis, with the pressure ring 11 fitted outside the adjusting seat 12.

[0041] When the pressure ring 11 and the adjusting seat 12 are assembled in place, the pressure ring 11 and the adjusting seat 12 respectively contact the rotating disk 21 on which the rotating adjusting pin 2 is located from both sides, thereby limiting the rotation of the adjusting pin 2 along the first axis. The rotating disk 21 is a boss structure protruding from the side wall of the rotating adjusting pin 2. The rotating disk 21 can be a complete circular ring structure or multiple independent protrusions located on the same circumference. Figure 2 As shown, the pressure ring 11 and the adjusting seat 12 are located on both sides of the rotating disk 21 on the first axis. The pressure ring 11 presses on the upper surface of the rotating disk 21, and the adjusting seat 12 presses on the lower surface of the rotating disk 21. The pressure ring 11 and the adjusting seat 12 cooperate to clamp the rotating disk 21. The pressure ring 11 and the adjusting seat 12 limit the rotation adjusting pin 2 on the first axis. Therefore, the rotation adjusting pin 2 can only rotate around the first axis and cannot translate along the first axis.

[0042] Combination Figure 1 , Figure 2As shown, the adjusting seat 12 is a cylindrical structure with a base plate and side walls. The top of the adjusting seat 12 is not closed, allowing the top-pressing limiting slider 3 to be inserted from the top. The base plate of the adjusting seat 12 has a through-channel along the first axis for the sliding column 31 to pass through. This channel allows the sliding column 31 to pass through, but the limiting block 32 cannot pass through. The limiting block 32 can press against the inner side of the base plate of the adjusting seat 12. Figure 2 The upper surface of the middle base plate is limited. The cross-sectional area of ​​the inner cavity of the adjusting seat 12 is larger than the cross-sectional area of ​​the limiting block 32. There is a certain gap between the inner cavity sidewall of the adjusting seat 12 and the limiting block 32 to prevent friction from forming on the sidewall of the limiting block 32.

[0043] Combination Figure 2 As shown, the rotary adjustment pin 2 includes a guide portion 22 and a drive portion 23, which are integrally formed to constitute the rotary adjustment pin 2. The cross-sectional area of ​​the guide portion 22 is larger than that of the drive portion 23, and the longitudinal cross-section of the rotary adjustment pin 2 is T-shaped. A rotating disk 21 is disposed on the outer periphery of the guide portion 22, and the height of the guide portion 22 is greater than the height of the rotating disk 21.

[0044] The outer side wall of the drive unit 23 is provided with an external thread, and the inner side wall of the pressure limiting slider 3 is provided with an internal thread. The external thread of the drive unit 23 mates with the internal thread of the pressure limiting slider 3. When the rotating adjusting pin 2 rotates around the first axis, the pressure limiting slider 3 can be moved along the first axis through thread transmission. By controlling the rotation direction of the rotating adjusting pin 2, rotating it clockwise or counterclockwise, the pressure limiting slider 3 can be moved along the first axis. Figure 2 It can be translated upwards or downwards.

[0045] The top of the pressure limiting slider 3 can press against the bottom surface of the guide portion 22, thereby limiting the maximum retraction position of the pressure limiting slider 3, such as... Figure 2 As shown, this illustrates the maximum outward extension position of the top pressure limiting slider 3. Figure 3 The diagram shows the maximum inward retraction position of the top-pressure limiting slider 3. When the top-pressure limiting slider 3 retracts to its maximum position, the limiting block 32 contacts the bottom surface of the guide portion 22, at which point the top-pressure limiting slider 3 cannot move further upward. Therefore, the top-pressure limiting slider 3 can only move upward within this position. Figure 2 and Figure 3 Move up and down within the range between them. Figure 3 The limiting block 32 is positioned at the top of the entire top pressure limiting slider 3 so that it can contact the bottom surface of the guide part 22. If the limiting block 32 is not at the top, the limiting block 32 will not contact the bottom surface of the guide part 22.

[0046] Combination Figure 2 , Figure 4As shown, a mounting channel 221 is provided perpendicular to the first axis on the guide portion 22. The mounting channel 221 is a blind hole. A pin 24 and an elastic element 25 are installed in the mounting channel 221. The elastic element 25 applies an outward elastic force to the pin 24, causing the pin 24 to tend to protrude from the guide portion 22. Positioning teeth 121 are provided on the inner wall of the adjusting seat 12. The positioning teeth 121 are arranged in a circle around the first axis, forming a circumferentially undulating wave structure on the inner wall of the adjusting seat 12. The height of the pin 24 is directly opposite the positioning teeth 121. When the rotating adjusting pin 2 rotates, it drives the pin 24 to rotate synchronously, and the pin 24 is used to engage with different positioning teeth 121. Figure 4 As shown, each positioning tooth 121 is a wave-shaped protrusion facing the first axis, forming a trough between two adjacent positioning teeth 121. The pin 24 is pressed inward by the positioning teeth 121, and the elastic element 25 is compressed. When the pin 24 passes through the trough, the pin 24 protrudes out of the elastic element 25 and elongates. By setting the pin 24 and the elastic element 25, a "click" sound can be generated during rotation, providing feedback to the user. Furthermore, when the pin 24 is engaged in the trough, it can achieve a certain self-locking effect.

[0047] Combination Figure 2 , Figure 3 As shown, the exposed surface of the guide portion 22 is flush with the support body 1, maintaining a flat appearance. The exposed surface of the guide portion 22 is provided with a turning groove 222 for turning, allowing the rotating adjusting pin 2 to be turned by inserting a flat object such as a coin. The turning groove 222 can be a straight groove, a cross-shaped groove, or other shaped slots. The design of the turning groove 222 prevents the rotating adjusting pin 2 from being turned by hand, thus preventing accidental operation.

[0048] Combination Figure 2 As shown, a first sealing ring 13 is provided on the outer side of the pressure ring 11 to form a seal between the pressure ring 11 and the external support structure. A second sealing ring 14 and a third sealing ring 15 are provided between the pressure ring 11 and the adjusting seat 12 to form a seal using the gap between the pressure ring 11 and the adjusting seat 12.

[0049] One end of the adjusting seat 12 is provided with a limiting flange 122, which is used to abut and limit the end of the pressure ring 11. Figure 2 As shown, a limiting flange 122 is provided at the bottom end of the adjusting seat 12. The limiting flange 122 is a circumferential boss formed perpendicular to the first axis. A third annular groove is provided at the other end of the adjusting seat 12 for placing the third sealing ring 15. The rotating disk 21 presses against the third sealing ring 15. Figure 2 The upper side wall of the adjusting seat 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 21 to squeeze the third sealing ring 15 from top to bottom.

[0050] The end of the pressure ring 11 is provided with a conical surface 111, which is combined with... Figure 2 As shown, a chamfer is provided at the lower inner edge of the pressure ring 11 to form a conical surface 111. A second annular groove is provided on the outer surface of the side wall of the adjusting seat 12 for placing the second sealing ring 14. The bottom surface of the second annular groove is a limiting flange 122. The conical surface 111 and the limiting flange 122 cooperate to compress the second sealing ring 14 and form a sealing effect.

[0051] An outer flange 112 is provided at the end of the pressure ring 11, and a first annular groove is provided on the outer surface of the side wall of the pressure ring 11 for the installation of the first sealing ring 13, such as... Figure 2 As shown, the top surface of the first annular groove is an outer flange 112, which forms a seal between the outer flange 112 and the support structure when the pressure ring 11 is installed.

[0052] Combination Figure 5 As shown, the side wall of the sliding column 31 has two cutting surfaces 311, which are used to cooperate with the channel provided on the base plate of the adjusting seat 12 to prevent rotation. The cross-section of the sliding column 31 should not be cylindrical; a non-cylindrical structure can form a circumferential limit on the sliding column 31, preventing it from rotating and allowing only translational movement. The number of cutting surfaces 311 can be set as needed. The cutting surfaces 311 can be planar or non-planar, as long as the side wall of the sliding column 31 forms a non-cylindrical shape. Each cutting surface 311 corresponds to a limiting block 32. Figure 5 As shown, two limit blocks 32 are set in total. A portion with a shrinkage is formed at the cutting surface 311. The limit blocks 32 are set at the cutting surface 311 to prevent the width of the entire top pressure limit slider 3 from becoming too large.

[0053] The sliding post 31 has a spherical end for abutting, combined with Figure 2 As shown, the lower end of the sliding column 31 is a closed structure, forming a spherical surface, which can contact the structure that needs to be pushed against. The spherical surface can reduce the contact area.

[0054] This utility model 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, used to rotate the rotating part around different axes. The two adjustment modules are used to adjust the position of the rotating part. When the top-pressing limit slider 3 of any one adjustment module reaches its maximum extended position, the rotating part is not locked and has not yet contacted the outer shell of the outdoor sight. Therefore, when the top-pressing limit slider 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.

[0055] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. 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 present invention. Therefore, the present 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.
