Description

Technical Field

[0001] The utility model belongs to the technical field of focusing mirrors, and in particular relates to a focusing mirror structure. Background Art

[0002] A focusing lens is a lens or lens assembly that can focus light onto a specific point. Its structure consists of a single lens or a combination of lenses, as well as possible connectors, guide grooves, and other mechanical components to ensure precise lens installation and positioning. The principle of a focusing lens is based on the law of refraction of light. When light passes from one medium to another, its propagation direction changes, or refracts. A focusing lens utilizes this principle by precisely designing the shape and refractive index of the lens, so that light from different directions converges to a single point, the focal point, after passing through the lens. The main function of a focusing lens is to focus light onto a specific point or area, thereby increasing the light intensity at that point.

[0003] Chinese Patent Publication No. CN216940478U relates to a focusing lens structure comprising a first connecting seat and a second connecting seat, each of which is provided with a first guide groove and a second guide groove, respectively. The first guide groove and the second guide groove are arranged opposite each other, and a focusing assembly is connected between the first connecting seat and the second connecting seat. The front and back surfaces of the focusing assembly are respectively located within the first guide groove and the second guide groove. The focusing assembly comprises a first focusing lens holder and a second focusing lens holder. The first focusing lens holder has a convex cross-section, and a lens is embedded in the bottom surface of the convex first focusing lens holder via a lens pressure ring. The top surface of the convex first focusing lens holder is provided with a second focusing lens holder that moves within the second guide groove. A lever is connected to the second focusing lens holder. This utility model enables quick installation while ensuring a tight seal.

[0004] During actual use, the utility model is usually assembled through a specific mounting structure, but the existing focusing lens structure generally relies on basic fixing components to stabilize the focusing lens, which lacks sufficient precision and stability. During actual operation, due to factors such as vibration, temperature changes or wear and tear due to long-term use, the position of the focusing lens is prone to unconscious shifting. This shift will not only directly lead to a decrease in the optical performance of the focusing lens, such as focal misalignment, blurred imaging, etc., but will also seriously affect the normal function of the focusing lens, greatly reducing the stability and reliability of the entire optical system. Utility Model Content

[0005] The utility model provides a focusing mirror structure in order to solve the problem of insufficient stability of the focusing mirror structure in the prior art.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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, rather than all the embodiments.

[0028] Example 1:

[0029] See also Figure 1-4 The present invention provides a focusing lens structure, comprising:

[0030] Mounting frame 1 and two connecting plates 2;

[0031] The mounting groove is provided in the mounting frame 1, and a matching positioning plate 3 is provided in the mounting groove. The positioning plate 3 is provided with a positioning opening through which a matching focusing lens body 4 is provided;

[0032] Multiple rectangular grooves are formed in the positioning plate 3. A limiting plate 5 is provided on one side of each of the rectangular grooves. One end of each of the limiting plates 5 extends through the multiple rectangular grooves into the positioning opening and abuts against one side of the focusing lens body 4.

[0033] Multiple snap-in grooves are respectively opened on both sides of the installation groove, and multiple snap-in grooves are respectively located on both sides of the multiple rectangular grooves. Corresponding snap-in rods 6 are provided in the multiple snap-in grooves, and the side walls of the positioning plates 3 located on both sides of the multiple rectangular grooves are provided with fixing grooves adapted to the snap-in rods 6.

[0034] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, a locking groove is provided at the upper end of the mounting frame 1, and a corresponding locking plate 7 is provided in the locking groove. The positioning plate 3 extends into the locking groove and is provided at the bottom end of the locking plate 7. By installing or removing the locking plate 7, the positioning plate 3 and the focusing lens body 4 are installed or removed.

[0035] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the locking plate 7 is provided with a plurality of fixing bolts 8, and the plurality of fixing bolts 8 all extend into the mounting frame 1. The plurality of fixing bolts 8 can limit the position of the locking plate 7, thereby limiting the position of the positioning plate 3 and the focusing lens body 4.

[0036] Specifically, such as Figure 2 As shown, a matching support ring 9 is provided on one side of the positioning port, and the focusing lens body 4 is against one side of the support ring 9 , and the support ring 9 can support the position of the focusing lens body 4 .
