detailed description

In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Please refer to FIG. 1 to FIG. 2 , the present invention provides a dimming mirror, which includes a fixing seat 5 , an adjusting seat 1 , a lens 2 , a first adjusting member and a second adjusting member.

The adjustment seat 1 includes a lens connection part and a mounting part, and the lens is fixed on the lens connection part. In this embodiment, the connecting part of the lens is a horizontal part 11, and the mounting part is a vertical part 12. The vertical part 12 connects the middle part of the horizontal part 11 in a T-shape, and the vertical part 12 is connected by the first adjusting part. connecting part. The purpose of setting the adjusting seat 1 into a T shape is to better cooperate with the fixing seat 5 . It can be said that the fixing seat is arranged in the space below the horizontal part 11 , and such a structure can better save space. In other embodiments, the shape and structure of the adjusting seat can be adjusted as required.

The lens 2 is fixed on the lens connection part. In this embodiment, the lens 2 is a reflective mirror, a red-transmitting green mirror or a blue-transmitting red-transmitting green light lens. In other embodiments, the lens 2 can be replaced with the required lens 2 as required. In this embodiment, a groove is formed on the connecting part of the lens, and the lens 2 is fixed in the groove by two-liquid mixed hardening glue. In other embodiments, the lens 2 can be fixed in the groove by other means, for example, engaging with the groove or adding gaskets into the groove for clamping.

The fixing base 5 , the fixing base 5 includes a connecting portion 51 and a fixing portion 52 connected to the connecting portion 51 . In this embodiment, the connecting portion 51 is perpendicular to the fixing portion 52 . The purpose of this is to facilitate the adjustment of the position of the adjustment seat 1 along the horizontal and vertical directions by the two adjustment parts respectively. Adjustment in the direction of the second adjustment member will affect the adjustment of the adjustment seat 1 along the direction of the fixed seat, so that the adjustment needs to be calibrated with each other multiple times, and an additional adjustment process is added. In other embodiments, the angles of the connecting portion 51 and the fixing portion 52 can be adjusted accordingly according to the requirements of the arrangement environment and the like. In this embodiment, the side surface of the connecting portion 51 is attached to the vertical portion 12 , and the top end of the connecting portion 51 touches the lower surface of the horizontal portion 11 . The purpose of this design is to make the structure between the adjusting seat 1 and the fixing seat 5 more compact, which can save more space. In other embodiments, the contact relationship between the adjusting base 1 and the fixing base 5 can be changed according to the needs of the actual installation environment. In this embodiment, the fixing seat 5 is processed from a cylinder, and the fixing seat 5 in this embodiment can be obtained by cutting the cylinder accordingly, which is easy to process and simple to manufacture. In other embodiments, the fixing seat 5 can also be made in other ways.

The first adjusting part, the connecting part 51 is connected with the installation part of the adjusting seat 1 through the first adjusting part. In this embodiment, the first adjusting member is used to adjust the vertical position of the adjusting seat 1 .

The second adjustment piece is connected to the fixing part 52 , and the first adjustment piece and the second adjustment piece cooperate to adjust the position of the adjustment seat 1 . In this embodiment, the second adjusting member is used to adjust the horizontal position of the fixing base 5 , thereby adjusting the horizontal position of the adjusting base 1 . The purpose of this design is to reduce the number of adjustments. The adjustments between the two adjustment parts do not interfere with each other, which can avoid repeated calibration and reduce the amount of operation. In other embodiments, the adjustment directions of the adjustment parts can be combined arbitrarily, only to ensure The adjusting seat 1 can be adjusted to a desired position. In this embodiment, the first adjusting member is a connecting screw 3, the second adjusting member is a fixing screw 4, a threaded hole is opened on the adjusting seat 1, and a through hole is formed on the connecting part 51, and the connecting screw 3 passes through the through hole Cooperate with the threaded hole to fix the connecting part 51 and the adjustment seat 1. There is a long and narrow hole on the fixed part 52. The fixing screw 4 passes through the long and narrow hole to fix the fixed seat 5. The long and narrow hole can be various types of holes, such as U-shaped holes. In other embodiments, other types of adjustment parts can be used, for example, using slide grooves to slidably connect the vertical part 12 of the adjustment seat 1 to the connecting part 51, and adjust the position of the adjustment seat 1 by sliding; The tightening device clamps the adjusting seat 1 on the connecting portion 51.

The working principle of the present invention will be described in detail below by taking this embodiment as an example.

When the position of the lens 2 needs to be adjusted, since the fixing part 52 of the fixing seat 5 is provided with a U-shaped hole, it is only necessary to loosen the fixing screw 4 a little and then adjust the position of the fixing seat 5 in the horizontal direction, and then the fixing Tighten the screw 4, thus completing the adjustment of the lens 2 in the horizontal direction; then loosen the connecting screw 4, adjust the angle of the adjusting seat 1 relative to the connecting part 51 a little, and then tighten the connecting screw 4, so that the adjusting seat The inclination angle of 1 changes, so that the vertical position of lens 2 changes. Since the light-adjustable mirror of the present invention is mainly for adjusting the angle of a single laser beam, the height change in the vertical direction brought about by the inclination is already Enough, thus the adjustment of the lens 2 in the vertical direction is completed, and the position adjustment of the lens 2 is realized through the cooperation of the two.

The present invention also provides a laser lamp, which includes the above dimming mirror 2 .

The structure of the dimming mirror 2 of the present invention is simpler than that of the prior art, so it is very convenient to add the dimming mirror 2 to the laser lamps of the prior art, without adding additional parts or doing too much remodel.

To sum up, the present invention fixes the lens through the adjusting seat, and then connects the adjusting seat and the fixing seat through two adjusting parts and adjusts the position of the adjusting seat, thereby realizing precise light adjustment with a simple structure and avoiding the occurrence of The problem of polarized light, and because of the simple structure, it is convenient to manufacture, operate and install, and the cost is reduced accordingly.

The above descriptions are only preferred feasible embodiments of the present invention, and do not limit the protection scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly used in other related technical fields, is also included in the scope of patent protection of the present invention.
