Technical Field
[0001] This utility model relates to the field of infrared lens mounting technology, specifically to a mounting structure for an infrared lens. Background Technology
[0002] With economic development and continuous improvement of science and technology, my country's infrared technology has developed very rapidly. Infrared lenses are being used more and more in daily life. Infrared lenses have the characteristics of compact structure, low power consumption, and low cost, and can be widely used in security fields such as forest fire prevention, road monitoring, and airport surveillance.
[0003] An existing patent (publication number: CN218446332U) discloses a snap-fit infrared lens, which uses a snap-fit mechanism inside the mounting base to efficiently and conveniently snap the infrared lens body into the mounting base. This facilitates the installation of the infrared lens body and the mounting base, making the infrared lens body more convenient to install and more stable during use, resulting in better shooting effects and greatly improving the practicality of the infrared lens.
[0004] However, the above technical solution still has certain defects. When the infrared lens body is removed, the above device only needs to pull the infrared lens body outward to disengage the positioning block from the positioning groove, thereby disengaging the locking block from the fixing groove and removing the infrared lens body. This makes the locking of the infrared lens body not firm. When the infrared lens body is pulled by external force, it will detach from the mounting base, which may cause the infrared lens body to fall and further damage the machine. Therefore, a locking structure for the infrared lens is proposed. Utility Model Content

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0027] The embodiments of this utility model will be described below based on its overall structure.
[0028] A snap-fit structure for an infrared lens, such as Figure 1-4 As shown, the device includes an infrared lens body 100, with a locking assembly 200 at its rear end. The locking assembly 200 includes a mounting base 210 that inserts into one end of the infrared lens body 100. A slot 220 is formed on the side of the mounting base 210 closest to the infrared lens body 100. A positioning post 230 matching the slot 220 is fixedly connected to the rear end of the infrared lens body 100. Four arc-shaped slots 231, equidistantly distributed in a circular pattern, are formed on the outer wall of the positioning post 230. A movable chamber is formed at a corresponding position on the inner wall of the slot 220. A receiving groove is formed on the side of the mounting base 210 away from the slot 220, and a rotating post is connected to the center of the receiving groove via a bearing. 240. A sun gear 250 is fixedly sleeved on the outer wall of the rotating column 240. Planetary gears 260 mesh on all four sides of the sun gear 250. A rotating shaft 270 is fixedly connected to one side of each of the four planetary gears 260. Each rotating shaft 270 extends through into the movable cavity and is fixedly connected to a rotating block 280. One end of the rotating column 240 extends through to the outside of the mounting base 210 and is fixedly connected to a rotating handle 290. The outside of the rotating handle 290 is provided with anti-slip texture. A second torsion spring 2910 is fixedly connected between the rotating handle 290 and the mounting base 210. The second torsion spring 2910 is sleeved on the outer wall of the rotating column 240. The protruding part of the rotating block 280 matches the arc-shaped slot 231.
[0029] The user first rotates the handle 290, causing the rotating column 240 to rotate, which in turn drives the sun gear 250 to rotate. At this time, the four sets of planetary gears 260 meshing with it will rotate synchronously, thereby driving the four sets of rotating shafts 270 and the rotating block 280 to rotate, retracting the rotating block 280 into the movable chamber. It is worth noting that at this time, the second torsion spring 2910 is twisted and tightened. Then, the positioning pin 230 at one end of the infrared lens body 100 is inserted into the slot 220 on one side of the mounting base 210. The handle 290 is then released, and the rotating column 240 is reversed under the action of the second torsion spring 2910, which, together with the sun gear 250 and the four sets of planetary gears 260, drives the rotating block 280 to rotate. The infrared lens body 100 is easily engaged with the mounting base 210 by the arc-shaped slot 231 on the outer wall of the positioning post 230. This makes the infrared lens body 100 easier to install and more stable during use, resulting in better shooting effects and greatly improving its practicality. When the infrared lens body 100 needs to be disassembled, simply rotate the handle 290 to release the limiting position of the positioning post 230 by the rotating block 280. Both disassembly and assembly are quick and easy. At the same time, the outer side of the handle 290 is provided with anti-slip texture to increase the friction of the outer wall of the handle 290 and prevent the user from slipping when rotating the handle 290.
[0030] Please refer to this carefully. Figure 1 and Figure 6 As shown, a hinge block 120 is fixedly installed at the top front end of the infrared lens body 100. A dust cover 110 is installed at one end of the hinge block 120. The dust cover 110 is located at the front end of the infrared lens body 100. A cleaning component 300 is provided inside the dust cover 110. The cleaning component 300 includes a circular groove 310 at the bottom end of the dust cover 110. A groove is provided at the center of the circular groove 310, and a motor 320 is fixedly installed in the groove. A mounting bracket 330 is fixedly connected to the output end of the motor 320. A cleaning brush 340 is fixedly installed on the other side of the mounting bracket 330. An annular sliding groove is provided on the inner wall of the circular groove 310. Both ends of the mounting bracket 330 are provided with ball bearings 350 that match and slide with the annular sliding groove.
[0031] Before use, the user first starts the motor 320. The output of the motor 320 drives the mounting bracket 330 to rotate, which in turn drives the cleaning brush 340 to rotate. The cleaning brush 340 is used to clean the infrared lens body 100. The annular sliding groove on the inner wall of the circular groove 310 cooperates with the ball bearings 350 at both ends of the mounting bracket 330, making the rotation of the mounting bracket 330 and the cleaning brush 340 more stable. Then, the dust cover 110 is opened, and the infrared lens body 100 can be used for shooting.
[0032] Please refer to section 1 and 2. Figure 5As shown, a limiting block 130 is fixedly connected to one end of the dust cover 110 away from the hinge block 120. A fixing block 140 is fixedly connected to the bottom front end of the infrared lens body 100. A rotating shaft is connected to one side of the fixing block 140 through a bearing, and a rotating block 150 is fixedly connected to the other end of the rotating shaft. A first torsion spring 160 is fixedly connected between the rotating block 150 and the fixing block 140. The first torsion spring 160 is sleeved on the outer wall of the rotating shaft.
[0033] By rotating the rotating block 150, the rotating block 150 and the limiting block 130 are misaligned, and the limiting of the dust cover 110 is released. The dust cover 110 flips up by itself through the hinge block 120. It is worth noting that the first torsion spring 160 will be twisted when the rotating block 150 rotates.
[0034] In use, rotating the handle 290 drives the rotating column 240 to rotate, which in turn drives the sun gear 250 to rotate. At this time, the four sets of planetary gears 260 meshing with it will rotate synchronously, thereby driving the four sets of rotating shafts 270 and the rotating block 280 to rotate, causing the rotating block 280 to rotate and retract into the movable chamber. It is worth noting that at this time, the second torsion spring 2910 is twisted and tightened. Then, the positioning pin 230 at one end of the infrared lens body 100 is inserted into the slot 220 on one side of the mounting base 210. The handle 290 is released, and under the action of the second torsion spring 2910, the rotation... The rotating column 240 reverses, cooperating with the sun gear 250 and four sets of planetary gears 260 to drive the rotating block 280 to rotate into the arc-shaped slot 231 opened on the outer wall of the positioning column 230 for engagement, thus completing the convenient engagement of the infrared lens body 100 and the mounting base 210. This makes the installation of the infrared lens body 100 more convenient and also makes the infrared lens body 100 more stable during use, resulting in better shooting effects. This greatly improves the practicality of the infrared lens body 100 during use. All parts not mentioned in this device are the same as or can be implemented using existing technologies.
