Detailed implementation manner

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the adjustment module of the present utility model will be introduced and described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0028] As Figure 1 shown, the present utility model discloses an adjustment module, which can be applied to the adjustment of devices such as aiming devices, for example, applied to the windage and elevation adjustment of aiming devices. The adjustment module includes structures such as an outer support shell 1, an adjusting screw 2, and an adjusting slider 3. The outer support shell 1 is fixedly assembled to the support structure, which is usually the outer shell or bracket structure of a certain product. After the outer support shell 1 is assembled, it remains fixed, and structures such as the adjusting screw 2 and the adjusting slider 3 are assembled on the outer support shell 1 to provide support.

[0029] The adjusting screw 2 is rotationally assembled to the outer support shell 1, and the adjusting screw 2 can rotate clockwise and counterclockwise relative to the outer support shell 1 around the axis; an installation channel is provided in the middle of the outer support shell 1, and the adjusting screw 2 is assembled in this installation channel. The adjusting screw 2 is axially limited relative to the outer support shell 1, and the adjusting screw 2 cannot move axially relative to the outer support shell 1. The end of the adjusting screw 2 is exposed to the outside for screwing, and the end of the adjusting screw 2 exposed to the outside does not require to protrude from the outer support shell 1. The end of the adjusting screw 2 exposed to the outside can protrude, be flush with, or be concave with respect to the outer support shell 1.

[0030] The adjusting slider 3 is a cylindrical structure with a through hole or a blind hole provided in the middle; the outer side wall of the adjusting slider 3 is circumferentially limited and cooperated with the inner cavity of the outer support shell 1. The outer side wall of the adjusting slider 3 is provided with a flat surface or a key structure. As Figure 4 shown, in this embodiment, the adjusting slider 3 is set as a flat square structure, and two mutually parallel planes are provided on the side wall. The adjusting slider 3 cannot rotate relative to the outer support shell 1, and the adjusting slider 3 can only translate axially relative to the outer support shell 1. When the adjusting screw 2 rotates, it drives the adjusting slider 3 to perform an axial displacement. As Figure 2 shown, the inner surface of the adjusting slider 3 is provided with a thread fit with the outer surface of the adjusting screw 2. When the adjusting screw 2 rotates relative to the outer support shell 1, the adjusting slider 3 cannot rotate and thus can only translate relative to the outer support shell 1, and a part of the structure of the adjusting slider 3 can move out and be exposed from the outer support shell 1; as Figure 2, when the adjusting screw 2 rotates clockwise, the adjusting slider 3 moves downward to expose the outer support shell 1 below; when the adjusting screw 2 rotates counterclockwise, the adjusting slider 3 moves upward and retracts. By the outward protrusion and retraction of the adjusting slider 3, it pushes or relaxes the device whose inclination needs to be adjusted, such as a telescopic sight or a laser module. During adjustment, the adjusting screw 2 can be rotated by hand, and the adjusting slider 3 makes an axial translation to achieve the pushing adjustment.

[0031] Since the adjusting screw 2 of the present utility model is axially limited and installed in the outer support shell 1, when the adjusting screw 2 rotates, the axial position of the adjusting screw 2 always remains unchanged, only circumferential rotation occurs, and the adjusting screw 2 always maintains its original axial position, with better aesthetics. The inability of the adjusting screw 2 to axially displace can achieve better sealing performance.

[0032] Based on the above solution, in combination with Figure 1 As shown, the outer support shell 1 of the present utility model includes a retaining ring 11 and a base 12. As Figure 2 shown, the retaining ring 11 and the base 12 are assembled and fixed relatively. By the cooperation of the retaining ring 11 and the base 12, the adjusting screw 2 is axially limited. The entire outer support shell 1 is formed by assembling two independent structures, which is convenient for production and processing and is convenient for achieving the axial limitation of the adjusting screw 2. The retaining ring 11 is assembled outside the base 12. The retaining ring 11 limits the adjusting screw 2 from above, and the base 12 limits the adjusting screw 2 from below. The retaining ring 11 is used for relative assembly with the support structure, and the base 12 is provided with a chamber for accommodating the adjusting slider 3.

[0033] In one embodiment, the retaining ring 11 is provided with an internal thread, and the base 12 is provided with an external thread. The retaining ring 11 and the base 12 are screwed together, which is convenient and fast for installation. In addition to screwing the retaining ring 11 and the base 12 together, the retaining ring 11 and the base 12 can also be fixed by means such as laser welding.

[0034] A second sealing ring 14 is arranged in the gap between the retaining ring 11 and the base 12 for sealing; in combination with Figure 2 As shown, an outwardly protruding bottom ring platform 122 is arranged at the lower edge of the base 12, and a second ring groove 123 is arranged above the bottom ring platform 122. The bottom surface of the second ring groove 123 is formed by the bottom ring platform 122; the second sealing ring 14 is installed in the second ring groove 123. A conical surface 111 is arranged at the bottom of the retaining ring 11. The inner diameter of the conical surface 111 is smaller at the top and larger at the bottom. When the retaining ring 11 and the base 12 approach each other axially, the conical surface 111 squeezes the second sealing ring 14 to achieve sealed assembly.

[0035] In combination with Figure 2As shown, a limiting ring platform 21 is provided on the outer periphery of the adjusting screw 2. An inner convex limiting retaining ring 112 is provided on the inner edge of the upper part of the inner wall of the pressing ring 11. The limiting retaining ring 112 of the pressing ring 11 presses on the upper surface of the limiting ring platform 21, and the upper end surface of the base 12 presses on the lower surface of the limiting ring platform 21. Under the axial limiting of the upper end surface of the base 12 and the limiting retaining ring 112, the adjusting screw 2 can be prevented from axially displacing, and the adjusting screw 2 can only rotate around the axis relative to the outer support shell 1.

[0036] Combined with Figure 2 As shown, a first sealing ring 13 is provided between the side wall of the pressing ring 11 and the support structure. A first annular groove 113 is provided on the side wall of the pressing ring 11. A top annular platform 114 is provided on the side wall of the pressing ring 11 protruding outward. The first annular groove 113 is located below the top annular platform 114, and the bottom surface of the top annular platform 114 forms one side surface of the first annular groove 113. The first sealing ring 13 is installed in the first annular groove 113. When the pressing ring 11 is installed on a support structure such as a housing, the first sealing ring 13 is used to seal the gap between the pressing ring 11 and the support structure.

[0037] A third sealing ring 15 is provided between the side wall of the adjusting screw 2 and the outer support shell 1, and the adjusting screw 2 and the outer support shell 1 axially press the third sealing ring 15; Combined with Figure 2 As shown, an inner convex annular platform 124 is provided on the inner cavity side wall of the base 12 of the outer support shell 1. The inner convex annular platform 124 protrudes inward from the inner cavity side wall of the base 12 to form an "L"-shaped step. When the base 12 and the pressing ring 11 are axially close to each other for assembly, the upper surface of the inner convex annular platform 124 presses the third sealing ring 15. The upper part of the adjusting screw 2 is a nut head, and the lower part is a threaded column. The outer diameter of the nut head is larger than the outer diameter of the threaded column. The third sealing ring 15 is sleeved outside the threaded column, and the lower surface of the nut head presses on the upper surface of the third sealing ring 15. The third sealing ring 15 is jointly pressed by the upper and lower cooperation of the nut head and the inner convex annular platform 124.

[0038] Based on any of the above technical solutions and their combinations, a receiving cavity is provided on the adjusting screw 2 along the radial direction. Combined with Figure 2 As shown, the receiving cavity is opened on the nut head of the adjusting screw 2, and the receiving cavity is a blind hole. A scale pin 41 and a scale spring 42 are provided in the receiving cavity. The scale spring 42 is used to radially press the scale pin 41 so that one end of the scale pin 41 radially moves out of the adjusting screw 2. The protruding end of the scale pin 41 is provided with a tapered or wedge-shaped shrinking tip structure. Combined with Figure 3As shown, the outer support shell 1 is provided with scale teeth 121, which are a circle of teeth. The scale pin 41 contacts the scale teeth 121 provided on the outer support shell 1 to provide scale feedback. When the adjustment pin 2 rotates relative to the outer support shell 1, the scale pin 41 rotates synchronously with the adjustment pin 2. The tip of the scale pin 41 contacts the scale teeth 121, and the teeth do not hinder the rotation of the scale pin 41. When the scale pin 41 is facing the depression between two teeth, its extension length is greater. When the scale pin 41 is facing a tooth, its extension length is reduced. When it moves from the position facing the tooth toward the depression, it will produce a "clicking" audible feedback. As the scale pin 41 rotates with the adjustment pin 2, it passes through multiple teeth, continuously emitting a "clicking" sound. During this repetitive process, the hand can feel clear feedback and hear the crisp "clicking" sound, which can be used to determine the specific adjustment value.

[0039] To ensure smooth rotation and minimize resistance, the tip of scale pin 41 is rounded, and the teeth are also rounded. The number of teeth is calculated based on the distance between the adjustment module and the rotation center of the sight's optical axis system, as well as the required adjustment accuracy. The higher the accuracy requirement, the greater the number of teeth and the smaller the rounding of the tip of scale pin 41.

[0040] The outer end surface of the adjusting pin 2 is provided with an adjusting groove 22 for screwing. Figure 1 、 Figure 2 As shown, the adjustment slot 22 can be a "I"-shaped groove. When rotating and adjusting, a flat object such as a flat screwdriver, a key, a coin, etc. can be used to rotate the adjustment pin 2.

[0041] Combine Figure 1 、 Figure 2 As shown, the upper edge of the outer wall of the adjustment slider 3 is chamfered to facilitate installation of the adjustment slider 3 into the cavity below the base 12. The lower edge of the outer wall of the adjustment slider 3 is provided with a spherical or conical surface, and the cross section has a contracting area from top to bottom. The small radial dimension of the lower end can avoid obstruction when contacting the relevant structures of the sight. Figure 1 、 Figure 2 In the structure shown, the radial dimension of the smallest part of the lower end of the adjusting slider 3 is set to a circular ring-shaped plane structure to avoid excessive curved surface occupying too much space, which helps to reduce the overall axial dimension.

[0042] The adjustment module of the utility model has a compact structure and is easy to use. It is smaller in size and more precise than traditional solutions used in the industry. It can be used on products with smaller overall structures. During adjustment, the hand feedback is clear, the sound is crisp, and the adjustment precision is high. There is reason to reduce the size of the entire machine, reduce the weight, and enhance the user experience.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
