Description

Technical Field

[0001] This utility model relates to the field of mirror frame technology, and in particular to a mirror adjustment device. Background Technology

[0002] Reflecting lenses are commonly used optical lenses, while mirror mounts are components that enable precise light transmission. Reflecting lenses are typically mounted on mirror mounts to precisely adjust their position and angle, ensuring accurate alignment and stability in different application scenarios.

[0003] Existing reflector mounts generally consist of three parts: a fixed plate, a movable plate for mounting the lens, and an adjusting screw threaded onto the fixed plate. One end of the adjusting screw is pressed against the movable plate, which is then elastically connected to the fixed plate via a tension spring (or compression spring). Rotating the adjusting screw adjusts the angle or distance of the movable plate relative to the fixed plate. However, after a period of use, the springs fatigue, leading not only to decreased adjustment accuracy but also to wobbling of the movable plate, causing instability in the optical path and affecting the performance. Utility Model Content

[0004] The purpose of this invention is to solve the problem of decreased accuracy and shaking caused by the short service life of spring connections in the prior art, and to propose a reflector adjustment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reflector adjustment device includes a fixed plate and a movable plate corresponding to the fixed plate, and also includes at least one set of screws threadedly connected to the fixed plate. A ball is fixedly disposed at one end of the screws extending into the movable plate, and a limiting hole that mates with the ball is provided in the movable plate.

[0007] To facilitate the installation of the screw, preferably, the fixing plate has multiple sets of threaded holes, and the screw is threaded into the threaded holes.

[0008] To facilitate the connection between the movable plate and the ball, the movable plate is further provided with multiple sets of mounting holes corresponding to the threaded holes. Each set of mounting holes is equipped with a connecting post. The limiting hole is coaxially opened in the connecting post, and the side wall of the connecting post is provided with a through groove that penetrates the limiting hole.

[0009] To ensure a reliable connection between the sphere and the connecting post, the limiting hole further includes a spherical cavity that mates with the sphere, and the connecting post has a flared hole. The small end of the flared hole is connected to the spherical cavity, and the diameter of the small end is smaller than the diameter of the spherical cavity.

[0010] Furthermore, a connecting rod is fixedly provided at one end of the screw, the ball is fixedly provided at the end of the connecting rod away from the screw, and the diameter of the connecting rod is smaller than the diameter of the ball. An adjustment knob is fixedly provided at the other end of the screw.

[0011] Preferably, a groove is formed on the outer wall of the screw, the groove extends along the axis of the screw, and a scale line is fixedly provided on the inner wall of the groove.

[0012] Compared with the prior art, the present invention provides a reflector adjustment device, which has the following advantages:

[0013] 1. This reflector adjustment device has a screw threadedly connected to a fixed plate, a ball fixedly installed at one end of the screw, and a connecting post detachably installed inside the movable plate. The connecting post has a spherical cavity that mates with the ball. This allows for universal adjustment of the movable plate while confining it to the fixed plate, ensuring the adjustment accuracy of the movable plate. Furthermore, the screw and connecting post are detachable, resulting in a simple structure, long service life, and convenient replacement, which helps improve the user experience.

[0014] 2. This reflector adjustment device, by having a groove on the screw and a scale line extending along the screw axis fixed in the groove, can achieve precise and rapid adjustment, thus improving the performance.

[0015] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model has a screw threadedly connected to a fixed plate, a ball fixedly installed at one end of the screw, a connecting column detachably installed inside the movable plate, and a spherical cavity that mates with the ball opened in the connecting column. This allows for universal adjustment of the movable plate while restricting the movable plate to the fixed plate, ensuring the adjustment accuracy of the movable plate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example:

[0024] Reference Figures 1-4 A reflector adjustment device includes a fixed plate 1 and a movable plate 2 corresponding to the fixed plate 1. The movable plate 2 has a connecting hole for mounting a reflector lens. Two sets of retaining rings are threaded into the connecting hole, allowing the reflector lens to be installed between the two sets of retaining rings, thus fixing the reflector lens onto the movable plate 2. This facilitates easy installation and removal and improves usability. The device also includes at least one set of screws 3, threaded onto the fixed plate 1. Preferably, there are three sets of screws 3, located at the three vertices of a square. The axis of the connecting hole coincides with the center point of the square, allowing for one set of screws to adjust the pitch and one set to adjust the yaw of the movable plate 2. The screws located at the right angles coordinate the pitch and yaw adjustments. Driving all three sets of screws 3 the same distance simultaneously allows the movable plate 2 to move along the Z-axis, further improving usability. A ball 303 is fixedly mounted on one end of each of the three sets of screws 3 extending into the movable plate 2, and a [missing information - likely a design feature] is provided within the movable plate 2. The limiting hole that mates with the ball 303 is used by threading a screw 3 onto the fixed plate 1. The ball 303 is fixedly installed at one end of the screw 3. The limiting hole that mates with the ball 303 is opened in the movable plate 2. On the one hand, it allows for universal adjustment between the ball 303 and the movable plate 2, making it convenient to adjust the angle and distance of the movable plate 2 relative to the fixed plate 1. On the other hand, it can restrict the movable plate 2 to the fixed plate 1. Moreover, the spring is eliminated, which not only extends the service life and reduces the cost of replacing the spring, but also prevents the movable plate 2 from shaking and improves the accuracy of use.

[0025] In use, a screw rod 3 is threaded onto the fixed plate 1, and a ball 303 is fixedly installed at one end of the screw rod 3. A connecting post 4 is detachably installed inside the movable plate 2, and a spherical cavity 401 that mates with the ball 303 is opened in the connecting post 4. This allows for universal adjustment of the movable plate 2 while confining it to the fixed plate 1, ensuring the adjustment accuracy of the movable plate 2. Furthermore, the screw rod 3 and the connecting post 4 are detachably connected, resulting in a simple structure, long service life, and convenient replacement, which helps improve the user experience. A groove 304 is opened on the screw rod 3, and a scale line extending along the axis of the screw rod 3 is fixedly installed in the groove 304, enabling precise and rapid adjustment and improving the performance.

[0026] Reference Figure 1 and Figure 2 Multiple sets of threaded holes 101 are provided on the fixed plate 1. The threaded holes 101 are provided in one to three sets, preferably three sets. The three sets of screws 3 are respectively threaded into the corresponding threaded holes 101. By threading the screws 3 into the threaded holes 101, it is not only convenient to adjust the rotation of the screws 3, but also to precisely adjust the angle or position of the movable plate 2, thereby improving the use effect.

[0027] Reference Figure 1 and Figure 2 Multiple sets of mounting holes 201 corresponding to the threaded holes 101 are provided on the movable plate 2. That is, there are three sets of mounting holes 201. The lines connecting the axes of the three sets of mounting holes 201 can form a square or an isosceles right triangle, and the axis of the connecting hole coincides with the center point of the square. This facilitates adjustment of the movable plate 2's pitch, yaw, or sliding along the axis of the connecting hole, improving usability. Connecting posts 4 are detachably installed in each set of mounting holes 201. The mounting holes 201 are preferably blind holes, with the bottom of the connecting post 4 abutting against the inner bottom of the mounting hole 201. Three sets of fixing holes are provided on the side wall of the movable plate 2, and these three sets of fixing holes are respectively connected to… The three sets of mounting holes 201 are connected, and a pin is threaded into each of the three sets of fixing holes. One end of the pin extends into the mounting hole 201 and abuts against the outer wall of the connecting column 4, thereby fixing the connecting column 4 in the mounting hole 201. This prevents the connecting column 4 from sliding in the mounting hole 201 during normal use, which would prevent it from functioning properly. A limiting hole is coaxially opened in the connecting column 4, and a through groove 402 is opened on the side wall of the connecting column 4 to pass through the limiting hole. During use, by opening the limiting hole in the connecting column 4 and opening the through groove 402 on the connecting column 4 to pass through the limiting hole, it is convenient to insert the ball 303 into the connecting hole, thus improving the performance.

[0028] Reference Figure 3 and Figure 4Here, we design the limiting hole as a spherical cavity 401 that mates with the ball 303. A flared hole is provided on the top end face of the connecting post 4, and the small end of the flared hole is connected to the spherical cavity 401. The large end of the flared hole and the top end face of the connecting post 4 are smoothly transitioned with rounded corners to reduce interference with the connecting rod 302. This increases the angle adjustment range of the movable plate 2 and improves the performance. Furthermore, the diameter of the small end is smaller than the diameter of the spherical cavity 401. The through groove 402 passes through the flared hole and the spherical cavity 401. In use, by using the limiting hole composed of the flared hole and the spherical cavity 401, we can not only ensure a reliable fit with the ball 303 to achieve universal adjustment, but also prevent the ball 303 from detaching from the spherical cavity 401 during use, thus improving the performance.

[0029] Reference Figures 2-4 A connecting rod 302 is fixedly installed on one end of the screw 3. A ball 303 is fixedly installed on the end of the connecting rod 302 away from the screw 3. The diameter of the connecting rod 302 is smaller than the diameter of the ball 303. The diameter of the connecting rod 302 is minimized as much as possible while ensuring the connection strength, which helps to reduce interference with the small end of the horn hole and improve the angle adjustment range of the movable plate 2. An adjustment knob 301 is fixedly installed on the other end of the screw 3. During use, the screw 3 can be easily driven to rotate by adjusting the knob 301. Moreover, by fixing the ball 303 to the screw 3 with the connecting rod 302, the adjustment range of the angle of the movable plate 2 can be increased as much as possible, thereby improving the performance.

[0030] Reference Figure 4 A groove 304 is provided on the outer wall of the screw 3. The groove 304 extends along the axis of the screw 3, and a scale line is fixedly provided on the inner wall of the groove 304. The scale line extends along the axis of the screw 3. In use, by fixing the scale line on the screw 3, quick and precise adjustment can be achieved, thereby improving the use effect.
