Description

Technical Field

[0001] The present application relates to the technical field of optical instruments, and more specifically, to a heat dissipation insulating lens for infrared thermal imaging detection. Background Art

[0002] An infrared thermal imager is an instrument that converts the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the thermal image represent the different temperatures of the object being measured. The infrared thermal imager uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution diagram of the target being measured and reflects it on the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image. The thermal image corresponds to the heat distribution field on the surface of the object.

[0003] Currently available infrared thermal imaging lenses will generate a certain amount of heat when in use. If the heat is difficult to dissipate, the high temperature generated by the accumulation of heat will affect its use and may cause volume expansion.

When the positioning plate 46 is located inside the positioning groove 411, the rotating plate 410 can be fixed in the slot 42.

[0046] The implementation principle of this embodiment is as follows: the heat dissipation and insulation component 3 is fixed to the outside of the lens 2 through two connecting components 4. When the thermal imager body 1 needs to be used, the user holds the hanging plate 316 to lift the protective plate 313 upwards, so that the connecting plate 314 is separated from the connecting groove 311, and the second magnet 315 can be separated from the first magnet 312. When the protective plate 313 is separated from the front side of the mounting cover 31, since the hanging plate 316 is in an "L" shape, the longer end of the "L" matches the size of the through groove 6. The user can fix the longer end of the hanging plate 316 in the through groove 6 opened in the mounting plate 5, which is convenient for placing the protective plate 313. 3 is placed on one side of the thermal imager body 1 for fixing, and the lens 2 can be used; after the subsequent use of the lens 2, the user separates the hanging plate 316 from the inside of the through groove 6, removes the protective plate 313, and then slides the connecting plate 314 set on one side of the protective plate 313 to connect it inside the connecting groove 311.

[0047] When the use of the thermal imager body 1 causes the lens 2 to generate heat, the fan 34 can be started to dissipate heat for the lens 2; the user starts the fan 34 through the central processor 36, and the first filter cotton 35 and the plurality of groups of second filter cotton 38 are arranged to isolate external impurities, and the fan 34 blows air into the cavity 32, and the wind is blown out from the plurality of groups of ventilation holes 33, and the blown wind dissipates heat for the lens 2;

[0048] When the second filter cotton 38 needs to be replaced, the second Velcro 39 provided on one side of the second filter cotton 38 can be separated from the first Velcro 37 by holding the cloth strip 310. At this time, the second filter cotton 38 can be separated from the inner side of the mounting cover 31.

The user holds the pull plate 45 and drives the positioning plate 46 to move outward through the connecting rod 44 to stretch the spring 48. When the positioning plate 46 is completely located inside the groove 43, the positioning plate 46 is disengaged from the positioning groove 411. The user then rotates the rotating plate 410 through the rotating shaft 49 to disengage the rotating plate 410 from the inside of the notch 42, and operates the connection component 4 on the right side at the same time. When the two rotating plates 410 are disengaged from the inside of the two notches 42, the heat dissipation insulation component 3 can be successfully disassembled from the outside of the thermal imager body 1. When the heat dissipation insulation component 3 is subsequently connected to one side of the thermal imager body 1, the user's hand When the pull plate 45 is pulled outward and the spring 48 is in an elongated state and the positioning plate 46 is located inside the groove 43, the rotating plate 410 can be located inside the slot 42. When the positioning slot 411 corresponds to the position of the positioning plate 46, the user releases the pull plate 45 and the pull plate 45 is reset by the setting of the spring 48. At this time, the positioning plate 46 rebounds forward and returns to its original position. When the positioning plate 46 is located inside the positioning slot 411, the rotating plate 410 is fixed inside the slot 42. At the same time, another connecting component 4 is operated. When the two rotating plates 410 are fixed inside the two slots 42, the heat dissipation insulation component 3 can be fixed to the outside of the thermal imager body 1. This structure is simple and convenient to operate, and is convenient for the staff to quickly disassemble and assemble the heat dissipation insulation component 3.
