[0022] 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.

[0023] See also Figure 1-5 The utility model provides an embodiment: a metal base for an infrared optical lens that is easy to replace, comprising: an upper connecting component 1, a lower connecting component 2 is provided at the lower end of the upper connecting component 1, the upper connecting component 1 includes a lens connecting ring seat 3 and a mounting base 5, and the mounting base 5 is hot-melt connected to the lower end of the lens connecting ring seat 3, a connecting groove 4 is provided inside the lens connecting ring seat 3, a threaded groove 17 is provided on the upper surface of the mounting base 5, and the threaded groove 17 passes through the mounting base 5 from top to bottom, and a fixing component 6 is connected to the inner thread of the threaded groove 17, and the lower connecting component 2 includes a connecting base 8 and a connecting base 8 located at the connecting base 8. The base 8 is provided with a fixing ear seat 7 on the outer wall around it, and a connecting hole 9 connected to the fixing component 6 is provided on the upper surface of the connecting base 8. The fixing component 6 includes a fixing column 11 and a lower limit seat 13 located on the lower surface of the fixing column 11. The upper end of the fixing column 11 is provided with an upper limit seat 12, and the upper limit seat 12 is fixed to the fixing column 11 by hot melt. The outer wall of the fixing column 11 is provided with a connecting thread 14, and the fixing column 11 is threadedly connected to the thread groove 17 through the connecting thread 14. The lower surface of the connecting base 8 is provided with an inner protective groove 10, and a mounting hole 18 is provided at the center of the fixing ear seat 7.

[0024] The upper limit seat 12 and the lower limit seat 13 at the top of the fixing pin 11 play a limiting role at both ends and prevent the fixing component 6 from being pulled up and falling off, thereby connecting the upper connecting component 1 and the lower connecting component 2. When replacing the infrared optical lens base, it is only necessary to press the lower limit seat 13 and push the lower limit seat 13 upward to separate the upper connecting component 1 from the lower connecting component 2, so that quick replacement is achieved without the need for tools and without disassembling the lower connecting component 2. The replacement cost is reduced, and the fixing component 6 can also be disassembled for secondary use, thereby improving utilization.

[0025] See also Figure 4 、 5 A positioning hole 15 is provided on one side of the connecting hole 9, and the opening of the positioning hole 15 is located on the upper surface of the connecting base 8. A positioning pin 16 is provided on the lower surface of the mounting base 5. The positioning pin 16 is inserted into the positioning hole 15. The lens connecting ring seat 3 is placed on the upper end of the lower connecting component 2. When placing it, the positioning pin 16 is aligned with the positioning hole 15 and inserted, which has a positioning and anti-drift effect, making it easy to quickly position the lens connecting ring seat 3 without having to adjust the position back and forth.

[0026] Furthermore, the lower limit seat 13 is made of a ductile metal material, and the lower limit seat 13 is two semicircles, and there is a gap in the middle of the two semicircles, which provides a deformation space when the lower limit seat 13 is squeezed. The ductile metal material can be pressed and deformed in the direction of the gap, making it easier for the lower limit seat 13 to move up and down along the connecting hole 9.

[0027] Working principle: When in use, the connecting base 8 is fixed to the support frame for supporting the infrared optical lens by means of the external screws of the fixing ear seat 7, and the bottom of the connecting base 8 is empty, which realizes the fixation of the lower connecting component 2, and then the lens connecting ring seat 3 is placed on the upper end of the lower connecting component 2. When placing it, the positioning pin 16 is aligned with the positioning hole 15 and inserted to play a positioning and anti-deviating effect, which is convenient for quickly positioning the lens connecting ring seat 3 without adjusting the position back and forth. At this time, the thread groove 17 and the connecting hole 9 are aligned, and then the end of the fixing component 6 with the lower limit seat 13 is inserted into the thread groove 17 from top to bottom. After it cannot be inserted, the upper limit seat 12 is rotated, and the fixing pin 11 is threadedly connected to the thread groove 17 through the connecting thread 14, driving the lower limit seat 13 to move downward, thereby improving the connection stability and avoiding fixation. When the component 6 is loose, after the lower limit seat 13 moves down and away from the connecting hole 9, the squeezing force is lost, and it expands to both sides. The upper limit seat 12 and the lower limit seat 13 at the top of the fixed plug 11 play a limiting effect at both ends and prevent the fixed component 6 from being pulled upward and falling, thereby realizing the connection between the upper connecting component 1 and the lower connecting component 2. The infrared optical lens is threadedly connected to the connecting groove 4 of the lens connecting ring seat 3 to realize the fixation of the infrared optical lens. When replacing the infrared optical lens base, it is only necessary to press the lower limit seat 13 and push the lower limit seat 13 upward to separate the upper connecting component 1 from the lower connecting component 2, thereby realizing quick replacement without the use of tools. Moreover, it can be replaced without disassembling the lower connecting component 2, thereby reducing the cost of replacement, and the fixed component 6 can also be disassembled for secondary use to improve utilization.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
