Description

Assembled infrared athermalization camera lens Technical Field The utility model belongs to the technical field of infrared athermalized lenses, and particularly relates to an assembled infrared athermalized lens. Background The infrared athermalized lens is an optical system specially designed for infrared wave bands, and has the core characteristics that stable imaging performance is maintained in a wide temperature range through special materials and structural design, and no external temperature control equipment is needed. At present, the multi-lens of infrared athermalization camera lens is fixed connection in the lens cone layer by layer, is inconvenient for the assembly of infrared athermalization camera lens, reduces packaging efficiency to when certain inside lens needs to be changed, need demolish other lenses, makes the change operation of lens inconvenient. Disclosure of utility model The utility model aims to solve the problems and provides an assembled infrared athermalized lens. In order to achieve the purpose, the utility model adopts the following technical scheme that the assembled infrared athermalized lens comprises: The pipe rack is in a round pipe shape; The lens cone is sleeved on the pipe support, one end of the lens cone is connected with the pipe support, and the axis of the lens cone is coincident with the axis of the pipe support; The support rings are inserted into the pipe frame from one side of the pipe frame, the support rings are propped against the inner wall of the lens cone, and the axle center of the support rings is overlapped with the axle center of the pipe frame; a plurality of lenses mounted within a plurality of the support rings, respectively; The connecting seat is in a circular tube shape, the connecting seat is connected with the other end of the lens barrel, and the axle center of the connecting seat is overlapped with the axle center of the lens barrel. As a further description of the above technical solution: The lens barrel comprises a lens barrel body and is characterized in that at least two limiting strips are arranged on the outer wall of the lens barrel body, the limiting strips are parallel to the axis of the lens barrel body, limiting grooves corresponding to the limiting strips are formed in the inner wall of the lens barrel body, and the limiting strips are clamped into the corresponding limiting grooves. As a further description of the above technical solution: the end of the pipe frame and the connecting seat are both provided with connecting flanges, and the connecting flanges are connected with the end of the lens cone through a plurality of bolts. As a further description of the above technical solution: The side wall of the pipe support is provided with a plurality of empty avoidance grooves which are uniformly arranged along the straight line direction at equal intervals, the inner wall of the pipe support is provided with positioning grooves corresponding to the empty avoidance grooves, and the support ring is clamped into the empty avoidance grooves and the positioning grooves. As a further description of the above technical solution: the connecting seat is a threaded pipe. In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: 1. According to the utility model, the pipe frame for supporting the lenses is designed to be separated from the lens barrel, the lenses are not required to be installed in the lens barrel layer by layer during lens assembly, the lenses are only required to be clamped on the pipe frame by virtue of the supporting rings, then the pipe frame is connected with the lens barrel, so that the assembly type installation of the lenses can be realized, the assembly efficiency of the lenses is greatly improved, and meanwhile, when a certain lens is replaced, only the supporting rings corresponding to the lenses are required to be pulled out after the pipe frame is separated from the lens barrel, and other lenses are not required to be removed, so that the replacement operation of the lenses is simple and convenient. 2. According to the utility model, through the clamping type structural design between the support ring and the pipe frame, the support ring is convenient to rapidly disassemble and assemble on the pipe frame, so that other lenses are not required to be disassembled when a certain lens is independently replaced, the assembly efficiency of the infrared athermalized lens is improved, and the replacement operation of the lenses is convenient.
