Compared with the prior art, the utility model discloses an infrared thermal imaging camera lens mounting structure sets up annular housing at the lens periphery and wraps up, protects the lens, and the extrusion is cracked when preventing to install, is provided with lip seal simultaneously at the lens periphery, plays further buffering protection to the lens.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the connection between the lens and the annular housing according to the present invention;
FIG. 3 is an enlarged view at A in FIG. 1;
the lens comprises a lens barrel 1, a lens barrel 2, lenses 3, an annular housing 4, a lens group 5, a sealing ring 6, a positioning bulge 7 and a threaded mounting hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
As shown in fig. 1 to 3, an infrared thermal imaging lens mounting structure includes a lens barrel 1, a lens 2 is mounted in the lens barrel 1, an annular housing 3 is disposed on an outer ring of the lens 2, a periphery of the lens 2 is embedded in the annular housing 3, and the periphery of the lens is protected by the annular housing 3; wherein, 3 processing circles have the mounting groove in annular housing, and the peripheral parcel of lens 2 has sealing washer 4, and lens 2 is gone into to the mounting groove all around through sealing washer 4 card in.
In this embodiment, sealing washer 4 adopts lip seal, and lip seal adopts trilateral parcel mode to surround 2 peripheries of lens tighter, plays buffer protection's effect, and lip seal makes 2 inseparabler in the mounting groove in addition, and the lens can not take place to rotate.
When the lens 2 is assembled with the lens barrel 1, the lens 2 is positioned and installed in the lens barrel 1 through the annular housing 3, wherein the inner side of the lens barrel 1 is provided with a positioning bulge 6; the back of the annular housing 3 is provided with a positioning groove which is not completely penetrated, the annular housing 3 is clamped on the positioning bulges 6 through the positioning groove, in the embodiment, the inner side of the lens 2 is provided with two positioning bulges 6, the positioning bulges 6 are symmetrically distributed on the inner side of the lens barrel 1, and the annular housing 3 is pre-fixed in the lens barrel 1 by utilizing the positioning bulges 6; a threaded mounting hole 7 is machined in the periphery of the annular housing 3; the periphery of the lens barrel 1 is provided with a counter bore, and the counter bore is connected with a threaded mounting hole 7 of the annular housing 3 through a counter screw to fix the lens 2 in the lens barrel 1.
The present invention is not limited to the above-described embodiments, and those skilled in the art can make modifications or changes without departing from the spirit of the present invention.
