Description

Technical Field

[0001] This application relates to the technical field of optical instruments, and more specifically, to a lens based on infrared thermal 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. Different colors on the thermal image represent different temperatures of the object being measured; the infrared thermal imager uses an infrared detector and an optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflects it onto the photosensitive elements of the infrared detector, thereby obtaining an infrared thermal image, and the thermal image corresponds to the thermal distribution field on the surface of the object.

[0003] Currently, the existing lenses for infrared thermal imaging will generate a certain amount of heat during use. If the heat is difficult to dissipate, the high temperature generated by the accumulation of heat will affect its use. There may be a phenomenon of volume expansion. After expansion, the lens will be squeezed, and it is easy to deform or even break, and even shorten its service life.

[0004] To solve the above problems, this application provides a lens based on infrared thermal detection. Utility Model Content

[0005] The lens based on infrared thermal detection provided by this application adopts the following technical solutions:

One side of the thermal imager body and outside the lens is connected with a heat dissipation and insulation component. There are two symmetrical connection components jointly arranged between the thermal imager body and the heat dissipation and insulation component. The heat dissipation and insulation component is connected to the thermal imager body through the connection component.

[0007] The heat dissipation and insulation component includes a mounting cover connected to the outside of the thermal imager body. A cavity is provided inside the mounting cover. A number of groups of equally spaced ventilation holes are provided around the inner wall of the mounting cover. A blower is provided at the top of the mounting cover. A first filter cotton is provided at the top of the blower. A central processor is provided at the top end of the mounting cover. Two symmetric first magic tapes are provided around the inner wall of the mounting cover. A second magic tape is adhered to one side of each first magic tape. A second filter cotton is jointly provided outside each two second magic tapes. There are four groups of the second filter cotton. A cloth strip is provided outside each second filter cotton. Two symmetric connection slots are provided on the front side of the mounting cover. A first magnet is embedded in the top of the front side of the mounting cover. A protection plate is connected to the front side of the mounting cover. Two symmetric connecting plates are installed on the rear side of the protection plate. A second magnet is embedded in the top of the rear side of the protection plate. A hanging plate is installed on the front side of the protection plate.

[0008] Through the above technical solution, the second filter cotton can be pulled by holding the cloth strip. The impurities in the outside can be filtered through the settings of the first filter cotton and the second filter cotton, and the protection effect on the lens is better. The settings of a number of groups of ventilation holes around the inner wall of the mounting cover can blow air on the lens evenly for heat dissipation.

[0014] Further, a connecting rod is connected inside the mounting seat at the position of the groove. One end of the connecting rod is connected with a pulling plate, and the other end of the connecting rod is installed with a positioning plate.

[0015] Through the above technical solution, when the pulling plate is pulled outwards by hand, the pulling plate drives the positioning plate to move through the connecting rod.

[0016] Furthermore, the diameter of the pull plate is larger than that of the connecting rod. One end of the connecting rod penetrates through and extends to the outside of the mounting seat, and the pull plate is located outside the mounting seat.

[0019] Furthermore, a spring is installed outside the mounting seat, and the spring is located outside the connecting rod. One end of the spring is connected to the pull plate.

[0020] Through the above technical solution, when the pull plate is pulled outwards, the spring is in a stretched state. When the pull plate is released, the pull plate springs back to its original position.

[0021] Furthermore, a rotating shaft is rotatably connected to the outside of the mounting cover. One end of the rotating shaft is provided with a rotating plate, and the rotating plate is located inside the notch.

The central processor 36 is electrically connected to the fan 34, and the fan 34 can be controlled by the central processor 36;

[0045] Please refer to Figure 6 、 Figure 7 and Figure 8, the connecting component 4 includes a mounting base 41 installed on the outer side of the thermal imager body 1. Inside the mounting base 41, a notch 42 and a groove 43 are respectively formed. A connecting rod 44 is connected at the position of the groove 43 inside the mounting base 41. One end of the connecting rod 44 is connected to a pulling plate 45, and the other end of the connecting rod 44 is installed with a positioning plate 46. The diameter of the pulling plate 45 is larger than that of the connecting rod 44. One end of the connecting rod 44 penetrates and extends to the outside of the mounting base 41. The pulling plate 45 is located outside the mounting base 41. A plurality of groups of anti-slip particles 47 distributed in a circular shape are arranged on the outer wall of the pulling plate 45. The anti-slip particles 47 are made of rubber material. A spring 48 is installed on the outside of the mounting base 41, and the spring 48 is located outside the connecting rod 44. One end of the spring 48 is connected to the pulling plate 45. A rotating shaft 49 is rotatably connected to the outside of the mounting cover 31. One end of the rotating shaft 49 is installed with a rotating plate 410. The rotating plate 410 is located inside the notch 42. A positioning groove 411 is formed inside the rotating plate 410. The positioning groove 411 and the positioning plate 46 are in a clamping structure;

[0046] The anti-slip particles 47 are provided to facilitate the user to pull the pulling plate 45 and increase the friction. The connecting rod 44 slides inside the mounting base 41. The rotating shaft 49 is rotatably connected to the outside of the mounting cover 31. When the positioning plate 46 is located inside the positioning groove 411, the rotating plate 410 can be fixed inside the notch 42.

[0047] The implementation principle of this embodiment is as follows: The heat dissipation and insulation component 3 is fixed outside 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 and lifts the protection plate 313 upward, so that the connecting plate 314 is separated from the connection groove 311, and the second magnet 315 can be separated from the first magnet 312. When the protection plate 313 is separated from the front side of the mounting cover 31, since the hanging plate 316 is in an "L" shape and the longer end of the "L" is adapted to the size of the through groove 6, the user can place the longer end of the hanging plate 316 inside the through groove 6 formed in the mounting plate 5 for fixation, which is convenient for placing the protection plate 313. The protection plate 313 is placed on one side of the thermal imager body 1 for fixation, and then the lens 2 can be used; after the lens 2 is used, the user separates the hanging plate 316 from the inside of the through groove 6, removes the protection plate 313, and then slides the connecting plate 314 provided on one side of the protection plate 313 into the connection groove 311. When the second magnet 315 is attached to the first magnet 312, the protection plate 313 can be fixed on one side of the mounting cover 31. At this time, the lens 2 can be placed inside the heat dissipation and insulation component 3 to protect the lens 2, prevent static electricity from being generated when the lens 2 contacts other objects, and play an insulating role at the same time, providing better protection for the lens 2;

[0048] When the heat generated by the use of the thermal imager body 1 causes heat in the lens 2, the blower 34 can be started to dissipate heat from the lens 2; the user starts the blower 34 through the central processing unit 36, and the first filter cotton 35 and several groups of second filter cotton 38 can isolate external impurities. The blower 34 blows air into the cavity 32, and at this time, the air blows out from several groups of ventilation holes 33, and the blown air dissipates heat from the lens 2.

[0049] When the second filter cotton 38 needs to be replaced, the second magic tape 39 provided on one side of the second filter cotton 38 can be detached from the first magic tape 37 by holding the position of the cloth strip 310. At this time, the second filter cotton 38 can be detached from the inner side of the mounting cover 31. When the second filter cotton 38 is subsequently connected inside the mounting cover 31, the second filter cotton 38 can be connected inside the mounting cover 31 only by the adhesion of the first magic tape 37 and the second magic tape 39.

[0050] The heat dissipation and insulation component 3 can be disassembled or installed as a whole through the connection component 4. When the heat dissipation and insulation component 3 needs to be disassembled, first operate the connection component 4 on the left side of the heat dissipation and insulation component 3. The user holds the pull plate 45 and drives the positioning plate 46 to move outwards through the connecting rod 44, stretching the spring 48. When the positioning plate 46 is completely inside the groove 43, the positioning plate 46 disengages from the positioning groove 411. The user then rotates the rotating plate 410 through the rotating shaft 49 to make the rotating plate 410 disengage from the inside of the notch 42. Then operate the connection component 4 on the right side. When the two rotating plates 410 disengage from the inside of the two notches 42, the heat dissipation and insulation component 3 can be successfully disassembled from the outside of the thermal imager body 1; when the heat dissipation and insulation component 3 is subsequently connected to one side of the thermal imager body 1, the user holds the pull plate 45 and pulls it outwards. When the spring 48 is in a stretched state and the positioning plate 46 is inside the groove 43, the rotating plate 410 can be located inside the notch 42. When the positioning groove 411 corresponds to the position of the positioning plate 46, the user releases the pull plate 45, and the pull plate 45 is driven to reset through the setting of the spring 48. At this time, the positioning plate 46 springs forward and resets. When the positioning plate 46 is inside the positioning groove 411, the rotating plate 410 is fixed inside the notch 42. Then operate the other connection component 4. When the two rotating plates 410 are fixed inside the two notches 42, the heat dissipation and insulation component 3 can be fixed on the outside of the thermal imager body 1; the operation method of this structure is simple and convenient, which is convenient for the staff to quickly disassemble and assemble the heat dissipation and insulation component 3.

[0051] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
