[0002] A lens is an optical element that uses the principle of light refraction to converge or diverge light. It is usually made of transparent material. To prevent the lens from being damaged, a lens fixing bracket is usually used to fix and support the lens.

[0003] After searching, for example, the patent with publication number CN215372321 U specifically discloses a bracket for fixing the headlight lens. The patent installs the lens on the bracket, then passes the bolt through the mounting hole on the shell, and fastens it with the thread on the bracket.

[0004] Different light sources have different beam characteristics. In some applications, the beam needs to be shaped, such as changing the shape or direction of the beam. However, conventional brackets are fixed, and it is difficult to change the shape or direction of the beam by adjusting the angle and position of the lens. Different types of brackets need to be replaced each time according to needs, which makes it difficult for the bracket to adapt to different application scenarios, thereby increasing light loss and reducing optical efficiency. Therefore, it is necessary to provide a lens fixing bracket to solve the above problems.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0032] like Figure 1-Figure 2 As shown, the present application provides a lens fixing bracket, including a connecting frame 1, a fixing ring 11 is threadedly connected to one side of the connecting frame 1, and a light outlet hole is opened at the end of the fixing ring 11. Therefore, when installing, the lens is first placed in the fixing ring 11, and then the fixing ring 11 is screwed onto the connecting frame 1 to fix the lens.

[0033] In order to facilitate the adjustment of the angle of the lens, a support frame 2 is fixedly installed on the side of the connecting frame 1 away from the fixing ring 11, and a mounting plate 3 is provided at the upper and lower ends of the support frame 2, and a disc 31 is fixedly installed at the other end of the mounting plate 3. At the same time, a base plate 4 is provided on the other side of the support frame 2, and an extension plate 41 is fixedly installed at the upper and lower ends of the base plate 4. The extension plate 41 is arranged on the inner side of the disc 31. In this application, a double-headed screw rod 34 is provided between the extension plate 41 and the disc 31, and the double-headed screw rod 34 is located at the center of the disc 31. The extension plate 41 and the disc 31 are connected by the double-headed screw rod 34. It can be understood that the extension plate 41 and the disc 31 can rotate around the double-headed screw rod 34.

[0034] In the present application, the base plate 4 is provided with fixing holes, through which the base plate 4 can be conveniently installed on equipment or large components.

[0035] like Figure 2-Figure 3 As shown, in order to prevent the mounting plate 3 and the disc 31 from shaking at will, an arc groove 35 is opened on the disc 31 with the stud screw rod 34 as the center. At the same time, a mounting hole 42 is opened on the extension plate 41. The mounting hole 42 corresponds to the arc groove 35, and a bolt 43 is passed through the mounting hole 42. The lower end of the bolt 43 is threadedly connected to a nut 44, and a gasket is sleeved on the bolt 43. During installation, after the bolt 43 is passed through the mounting hole 42 and the arc groove 35, the gasket is inserted and the nut 44 is tightened to fix the disc 31 and the extension plate 41.

[0036] In order to adjust the position of the lens, such as Figure 2 and Figure 4 As shown, the upper and lower ends of the support frame 2 are fixedly mounted with slides 21, and the end of the mounting plate 3 away from the disc 31 is provided with a slide groove 33, and the slide groove 33 and the slide 21 are slidably engaged;

[0037] At the same time, multiple groups of holes 32 are formed on both sides of the mounting plate 3. The holes 32 are located on both sides of the slide groove 33, and the two sides of the end of the slide plate 21 close to the mounting plate 3 are provided with a contraction groove 211. A clamping member 22 is fixedly installed in the contraction groove 211. The clamping member 22 has a protrusion 221 that is slidably connected to the contraction groove 211. The outer end of the protrusion 221 is provided with an arc angle. A spring 222 is fixedly installed between the protrusion 221 and the contraction groove 211. In the present application, the protrusion 221 and the hole 32 cooperate with each other. Under normal conditions, the slide plate 21 is located in the slide groove 33, and the protrusion 221 is protruded outward by the elastic force of the spring 222 and is stuck in the hole 32, thereby preventing the slide plate 21 from sliding in the slide groove 33.

[0038] To summarize: when adjusting the lens angle, the operator manually loosens the nut 44, then holds the connecting frame 1 to drive the support frame 2, the mounting plate 3, and the disc 31 to rotate along with the stud screw 34. Due to the provision of the arc groove 35, when the disc 31 rotates, the bolt 43 is not affected. After adjusting to the appropriate angle, the operator tightens the nut 44 to fix the disc 31 and the extension plate 41 to prevent shaking and free rotation.

[0039] When the lens position needs to be adjusted, the operator holds the connecting frame 1 and pulls the slide plate 21 outward. Due to the setting of the arc angle of the outer end of the protrusion 221, the protrusion 221 will slide inward after being pulled and shrink the spring 222 until it reaches the next hole 32. The protrusion 221 will be ejected outward by the rebound force of the spring 222 and re-insert into the hole 32 until it is adjusted to the appropriate position. This makes it convenient to change the shape or direction of the light beam by adjusting the angle and position of the lens. There is no need to replace different types of brackets according to needs each time, which improves the flexibility of the bracket, can adapt to different application scenarios, reduce light loss, and improve optical efficiency.

[0040] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
