Abstract
Description
Technical Field
[0001] This utility model belongs to the field of adjustment parts technology and relates to a precision fine-tuning component. Background Technology
[0002] In existing technologies, night vision devices or other fields require the telescopic function of a telescopic rod to work in conjunction with other parts to achieve adjustment. However, the fine-tuning components in existing technologies can only make approximate adjustments and cannot achieve more precise adjustments. The more precise the instrument, the more precise the fine-tuning components it needs. Summary of the Invention
[0003] In view of this, the purpose of this utility model is to provide a fine-tuning component that can achieve precise adjustment function.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A precision fine-tuning component includes a fine-tuning rotor and a fine-tuning cap that cooperate with each other. The fine-tuning cap is fitted onto the fine-tuning rotor to axially limit its movement. The fine-tuning rotor can rotate within the fine-tuning cap. The bottom surface of the fine-tuning rotor has an internally threaded hole in the middle. The upper end of the fine-tuning pin extends into the internally threaded hole and engages with its threads. A fine-tuning seat is provided below the fine-tuning rotor. The fine-tuning seat is a cylindrical structure with an open top. After the fine-tuning seat is fitted onto the outside of the fine-tuning rotor, the upper end of the fine-tuning seat is fixed to the lower end of the fine-tuning cap. The lower end of the fine-tuning pin extends through the fine-tuning seat and extends to the fine-tuning seat below the fine-tuning cap. A ring of fine-tuning anti-slip texture is provided on its inner wall. A retractable fine-tuning tip is provided on the fine-tuning rotor corresponding to the fine-tuning anti-slip texture. The fine-tuning tip cooperates with the fine-tuning anti-slip texture. When the fine-tuning rotor is rotated, the fine-tuning tip jumps on the fine-tuning anti-slip texture.
[0006] Furthermore, a radial through hole is opened in the middle of the fine-tuning rotor. The center line of the radial through hole intersects with the axis of the fine-tuning rotor. One side of the radial through hole is set as a stepped hole. The fine-tuning tip is located in the stepped hole. The fine-tuning tip is provided with a limiting step two that cooperates with the stepped hole. The rear end of the fine-tuning tip abuts against one end of the fine-tuning spring. The other end of the fine-tuning spring abuts against the limiting block. The limiting block is fixed at the other end of the radial through hole. The fine-tuning spring is in a compressed state. Under the elastic force of the fine-tuning spring, the end of the fine-tuning tip extends out to the outside of the radial through hole and abuts against the fine-tuning anti-slip texture.
[0007] Furthermore, the lower end of the fine-tuning seat has a through hole to facilitate the passage of the fine-tuning pin, which extends to the outside of the fine-tuning seat. The fine-tuning seat provides axial positioning for the fine-tuning rotor and the fine-tuning pin.
[0008] Furthermore, the upper end face of the fine-tuning rotor is provided with a cross structure for adjusting the fine-tuning rotor, and the cross structure is used in conjunction with a tool.
[0009] Furthermore, the upper part of the interior of the fine-tuning cover is configured with a stepped hole that matches the limiting step of the fine-tuning rotor.
[0010] The beneficial effects of this utility model are as follows:
[0011] The fine-tuning seat of this utility model not only serves as a limiting function, but also has fine-tuning anti-slip texture added to the inner wall of its upper part. In conjunction with the elastic fine-tuning tip, when the fine-tuning rotor rotates, the fine-tuning tip rotates accordingly. When the fine-tuning tip rotates, it will bounce on the fine-tuning anti-slip texture, accompanied by a sound. In this way, the sound of the fine-tuning tip rotating can indicate how many internal threads the fine-tuning tip has bounced, thereby achieving more precise fine-tuning. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] As shown in the figure, a lightweight multi-functional laser pointer includes a housing 1. An illumination head 2 is located at one end of the housing 1, and is threaded to the end of the housing 1. Normally, a battery compartment cover is screwed onto the housing 1 at the position corresponding to the illumination head 2. The battery compartment cover is removable and replaceable to ensure the user can use the machine normally when the illumination head 2 is not in use. If the illumination head 2 needs to be used, the battery compartment cover is removed and the illumination head 2 is installed. The battery compartment 11 is located inside the housing 1 at the rear of the illumination head 2. Inside the other side of the housing 1 is a three-light assembly 3. An infrared supplement light 32 is located on the side of the three-light assembly 3 closest to the illumination head 2. Visible red lasers 33 and infrared spot lasers 34 are distributed vertically on the side away from the illumination head 2. The visible red lasers 33 and infrared spot lasers 34 are symmetrically arranged with respect to the infrared supplement light 32, and their axes are located in the same vertical plane.
[0028] The lighting head 2, infrared fill light 32, visible red laser 33 and infrared spot laser 34 are electrically connected to the control unit inside the outer casing 1, and the control unit controls the lighting head 2, infrared fill light 32, visible red laser 33 and infrared spot laser 34.
[0029] A Hall switch 4 is installed in the middle of the housing 1 between the lighting lamp head 2 and the three-light assembly 3. The Hall switch 4 is electrically connected to the lighting lamp head 2 and is used to control the lighting mode of the lighting lamp head 2.
[0030] A laser button 12 is provided on the upper surface of the outer shell 1 near the rear end of the three-light assembly 3. A gear switch 13 is provided on the end of the outer shell 1 at the tail end of the lighting head 2. The gear switch 13 and the laser button 12 work together to control the on and off of the three laser heads, namely the infrared fill light 32, the visible red laser 33 and the infrared dot laser 34, and to adjust their gears. The gear switch 13 and the laser button 12 are electrically connected to the control unit to achieve control.
[0031] A white light button 14 is provided on the outer shell 1 in front of the laser button 12. The white light button 14 is used to control the lighting head 2. The laser button 12 is parallel to the outer shell 1. The white light button 14 is electrically connected to the control unit. The angle between the white light button 14 and the laser button 12 is an obtuse angle. The angle between the white light button 14 and the laser button 12 is between 130 degrees and 140 degrees. This setting allows the operator's thumb to naturally rest on the white light button 14 and the laser button 12 to form an ergonomic angle, making it easy for the thumb to control the two buttons at the same time. This is both comfortable and allows for one-handed operation.
[0032] A focusing wheel 51 is provided on the outer shell 1 in front of the white light button 14. The focusing wheel 51 is the operating part of the focusing mechanism 5. The focusing mechanism 5 is connected to the infrared fill light 32 and is used to adjust the aperture size of the infrared fill light 32.
[0033] The upper part of the outer shell 1 in front of the white light button 14 is provided with a fine-tuning component 6 that works with the three-light component 3. The fine-tuning component 6 can adjust the three-light component 3 so that the light emitted by the visible red laser 33 and the infrared dot laser 34 is at the same point as the firing point of the gun.
[0034] The three-light assembly 3 is connected to the housing 1 via a three-light housing 31, which is an integral shell. The housing 31 has mounting holes corresponding to the infrared supplementary light 32, the visible red laser 33, and the infrared point laser 34, respectively. After the infrared supplementary light 32, the visible red laser 33, and the infrared point laser 34 are installed into their corresponding holes, they are calibrated and then fixed with set screws and adhesive. The housing 31 has threaded holes and glue injection holes 313 at corresponding positions to mate with the set screws. The housing 31 has four evenly distributed set screws on the same radial plane. Priority is given to adjusting the alignment of the three lights. Only after the alignment of the three lights is completed is the overall alignment of the three-light assembly with the external product adjusted. After injecting adhesive into the glue injection hole 313, the adhesive undergoes a cooling process. During this cooling process, the three lights are calibrated by adjusting the set screws. After calibration, the adhesive is allowed to completely solidify.
[0035] The outer front end of the three-light outer shell 31 is a hemispherical structure 311. The corresponding inner part of the outer shell 1 is provided with a hemispherical groove corresponding to the hemispherical structure 311. Spherical grooves are symmetrically distributed on the upper and lower sides of the hemispherical structure 311. A limiting ball 35 is placed in the spherical groove. At the same time, a spherical groove that cooperates with the limiting ball 35 is opened in the hemispherical groove. In this way, the limiting ball 35 limits the hemispherical structure 311 axially and radially, so that the hemispherical structure 311 cannot move back and forth or rotate, but can swing slightly.
[0036] The tail end 312 of the three-light housing has a rectangular structure. A spring 36 abuts against the lower part of the three-light housing 31 and the side near the infrared supplementary light 32. A limiting groove for placing the spring 36 is provided inside the housing 1. The other two sides of the tail end 312 of the three-light housing abut against the fine-tuning top post 63 of the fine-tuning component 6. The fine-tuning top post 63 is retractable. By adjusting the fine-tuning rotor 62 of the fine-tuning component 6 located outside the housing 1, the retraction of the fine-tuning top post 63 can be achieved, thereby adjusting the position of the tail end 312 of the three-light housing. This causes the three-light housing 31 to swing, so that the emission points of the visible red laser 33 and the infrared dot laser 34 coincide with the emission point of the gun.
[0037] The fine-tuning assembly 6 includes a fine-tuning rotor 62 and a fine-tuning cover 61 that cooperate with each other. The fine-tuning cover 61 has a through hole in the middle and is fitted onto the fine-tuning rotor 62. The fine-tuning cover 61 and the fine-tuning rotor 62 are coaxial, and the fine-tuning rotor 62 can rotate within the fine-tuning cover 61. The upper end face of the fine-tuning rotor 62 is provided with a cross structure 621 for adjusting the fine-tuning rotor 62. The cross structure 621 is used with a cooperating tool. The upper part of the interior of the fine-tuning cover 61 is provided with a stepped hole that cooperates with a limiting step of the fine-tuning rotor 62, and the fine-tuning cover 61 limits the movement of the fine-tuning rotor 62.
[0038] The bottom surface of the fine-tuning rotor 62 has an internally threaded hole in the middle. The upper end of the fine-tuning pin 63 extends into the internally threaded hole and is threaded into it. A fine-tuning seat 64 is located below the fine-tuning rotor 62. The fine-tuning seat 64 is a cylindrical structure with an open top. After the fine-tuning seat 64 is fitted over the fine-tuning rotor 62, its upper end is fixed to the lower end of the fine-tuning cover 61. The lower end of the fine-tuning seat 64 has a through hole for the fine-tuning pin 63 to pass through. The fine-tuning pin 63 extends outside the fine-tuning seat 64, limiting the movement of the fine-tuning rotor 62 and the fine-tuning pin 63. This allows the fine-tuning rotor 62 to rotate within the space enclosed by the fine-tuning cover 61 and the fine-tuning seat 64. Rotating the fine-tuning rotor 62 converts its rotation into linear motion of the fine-tuning pin 63, thereby adjusting the tail end 312 of the three-sided outer shell.
[0039] The fine-tuning seat 64 extends to the lower part of the fine-tuning cover 61. A ring of fine-tuning anti-slip texture 641 is provided on its inner wall. A radial through hole 622 is opened in the middle of the fine-tuning rotor 62 corresponding to the fine-tuning anti-slip texture 641. The center line of the radial through hole 622 intersects the axis of the fine-tuning rotor 62. A stepped hole is provided on one side of the radial through hole 622. A fine-tuning tip 65 is placed at the stepped hole. The fine-tuning tip 65 is provided with a limiting step 2 that cooperates with the stepped hole. The rear end of the fine-tuning tip 65 abuts against one end of the fine-tuning spring 66. The other end of the fine-tuning spring 66 abuts against the limiting block 67. The limiting block 67 is fixed at the other end of the radial through hole 622. The fine-tuning spring 66 is in a compressed state. Under the elastic force of the fine-tuning spring 66, the end of the fine-tuning tip 65 extends out to the outside of the radial through hole 622 and abuts against the fine-tuning anti-slip texture 641. When the fine-tuning rotor 62 is rotated, the fine-tuning tip 65 bounces on the fine-tuning anti-slip texture 641, making a slight sound. Each bounce of the fine-tuning tip 65 produces a slight sound, so the number of bounces of the fine-tuning tip 65 can be judged by the sound, thereby achieving more precise fine-tuning of the fine-tuning rotor 62.
[0040] The fine-tuning cover 61 is fixedly connected to the corresponding hole on the outer casing 1 by screws.
[0041] The focusing mechanism 5 includes a first pull rod 53 connected to a focusing wheel 51. The focusing wheel 51 is exposed on the outside of the outer casing 1 and can rotate. The focusing wheel 51 is connected to the outer casing 1 via a rotating shaft. One end of the first pull rod 53 is fixed to the end face of a fine-tuning rotating shaft 52 inside the outer casing 1. The first pull rod 53 is eccentrically connected to the fine-tuning rotating shaft 52. The other end of the first pull rod 53 is fixedly connected to one end of a second pull rod 54. The other end of the second pull rod 54 is connected to an infrared supplementary light 32 via a focusing bolt 55. An elliptical oblong hole 314 is opened on the three-light outer casing 31 that mates with the focusing bolt 55. The oblong hole 314 has a length of... The focusing bolt 55 is fixed to the infrared filler lamp 32 after passing through the elongated hole 314 in the direction of the focusing direction parallel to the axis of the infrared filler lamp 32. The end of the second pull rod 54 is hinged to the focusing bolt 55, and the focusing bolt 55 can slide in the elongated hole 314. When the focusing wheel 51 is turned, since the first pull rod 53 is eccentrically connected to the fine adjustment shaft 52, the rotation of the fine adjustment shaft 52 will drive the first pull rod 53 to move. The first pull rod 53 drives the second pull rod 54, the second pull rod 54 drives the focusing bolt 55, and the focusing bolt 55 drives the infrared filler lamp 32 to slide in the hole of its corresponding three-light housing 31 to achieve the focusing function.
[0042] A clamping mechanism 7, integral with the outer shell 1, is provided at the lower rear of the outer shell 1 on one side of the three-light assembly 3. The clamping mechanism 7 is used to clamp the laser designator on the gun's rail. When the laser designator is installed on the gun, the axes of the visible red laser 33 and the infrared dot laser 34 are located in the same plane as the central axis of the gun.
[0043] An end cap 8 is provided at the end of the outer shell 1 on one side of the three-light component 3. The end cap 8 covers the laser head of the three-light component 3 to provide protection.
[0044] The arrangement of the Hall switch 4, laser button 12, gear switch 13, white light button 14, and focus wheel 51 allows the user to operate with one hand. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
