Description

Technical Field

[0001] This utility model relates to the field of infrared temperature measurement windows, specifically an infrared temperature measurement window with a drive shaft that can be combined. Background Art

[0002] An infrared temperature measurement window is a specific area or component used in infrared temperature measurement technology. Infrared temperature measurement technology measures the temperature of an object based on the infrared radiation emitted by the object. An infrared temperature measurement window is usually a transparent or semi-transparent component that allows infrared radiation to pass through while blocking or reducing interference from visible light and ultraviolet rays. This design ensures that the infrared temperature measurement device can accurately and efficiently receive the infrared radiation of the target object, thereby performing precise temperature measurement. Infrared temperature measurement windows have wide applications in medical, industrial, and military fields.

[0003] Chinese patent CN208238949U discloses a rotating explosion-proof infrared temperature measuring window with electrical detection function. It includes a limiting device consisting of a left limiting spring, spring A, a fixed plate A, a right limiting spring, spring B, and a fixed plate B. The left limiting spring and fixed plate A are fixed to one side wall of an arc groove. Spring A is fixed between the bent part of the left limiting spring and the fixed plate A. Limiting rings A and B slide into the arc plate. Springs A and B restore their deformation to support the limiting rings A and B, thus fixing the window cover and explosion-proof cover. When opening is required, the window cover is rotated, springs A and B deform again, and the limiting rings A and B slide out of the arc groove to open. It is simple to use, avoids errors in temperature measurement, and has strong explosion-proof function.

[0004] In actual use, the explosion-proof infrared temperature measurement window of the aforementioned patent can only have its inner and outer covers rotate synchronously, and one of the covers cannot be disassembled separately, which affects the performance during actual use.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] To address the issue that existing explosion-proof infrared temperature measurement windows only allow for synchronous rotation of the inner and outer covers during actual use, preventing the individual removal of one cover and thus affecting performance, this embodiment provides the following technical solution:

[0022] An infrared temperature measurement window with a drive shaft combustible includes a base 1, a transparent light-transmitting crystal 8 disposed in the middle of the interior of the base 1, a first cover plate 5 disposed at the front end of the light-transmitting crystal 8, and a second cover plate 6 disposed at the rear end of the light-transmitting crystal 8, such as... Figure 1 and Figure 2 As shown, when the external temperature measurement window is not in use, the two ends of the light-transmitting crystal 8 are wrapped and protected by the first cover plate 5 and the second cover plate 6 respectively, according to the installation requirements.

[0023] In this embodiment, as Figure 1 As shown, a grounding continuity test hole 2 for grounding testing is provided on the upper end of one side of the base 1. The tester can measure the base 1 and the infrared temperature measurement window as a whole through the grounding continuity test hole 2.

[0024] In this embodiment, a movable hole 17 for connection and transmission is provided on one side of the light-transmitting crystal 8, and the movable hole 17 extends through and to both ends of the base 1, such as... Figure 2 and Figure 3 As shown, a second connecting shaft 10 is provided inside the movable hole 17 at one end facing the first cover plate 5. A connecting ring 11 is provided around the middle position of the outside of the second connecting shaft 10. A reserved cavity 12 is provided outside the connecting ring 11 and is recessed inside the base 1. The outside of the connecting ring 11 is connected to the internal slot of the reserved cavity 12. The second connecting shaft 10 is rotatably fixed at the position of the movable hole 17 through the connecting ring 11. The second connecting shaft 10 is used to drive and connect the second cover plate 6 and the first cover plate 5 at both ends.

[0025] In this embodiment, a first recessed cavity 15 is provided on the upper side of the second connecting shaft 10 facing the second cover plate 6, and a first connecting shaft 9 for transmission is provided on the end of the second cover plate 6 facing the movable hole 17, such as... Figure 4 and Figure 5 As shown, a second recessed cavity 16 is provided on the lower side of the first connecting shaft 9 facing the second connecting shaft 10. In actual installation, the first connecting shaft 9 can be locked in the second connecting shaft 10 with the first recessed cavity 15 through the second recessed cavity 16. The recesses of the second recessed cavity 16 and the first recessed cavity 15 facilitate the first connecting shaft 9 and the second connecting shaft 10 to rotate together and drive the first cover plate 5 and the second cover plate 6 to rotate at the same time.

[0026] In this embodiment, a first embedding cavity 13 is provided at the upper end between the first recessed cavity 15 and the second recessed cavity 16, and a second embedding cavity 14 is provided at the lower end between the first recessed cavity 15 and the second recessed cavity 16, such as... Figure 5 As shown, the first embedding cavity 13 and the second embedding cavity 14 are joined together to form a circle;

[0027] In this embodiment, a fixing hole 3 is provided at one end of the first embedding cavity 13 and the second embedding cavity 14 spliced ​​together to form the center position. The fixing hole 3 penetrates the base 1 and extends to the outside, such as... Figure 2 and Figure 4 As shown, a first set screw 4 is provided through the inside of the fixing hole 3, and the outside of the first set screw 4 is threadedly engaged with the threaded wall inside the fixing hole 3. As the first set screw 4 rotates continuously, it extends into the first embedding cavity 13 and the second embedding cavity 14. After the first set screw 4 is embedded and fits the first connecting shaft 9 and the second connecting shaft 10, the second connecting shaft 10 and the first cover plate 5 and the second cover plate 6 connected to the first connecting shaft 9 can be fixed.

[0028] In this embodiment, the first cover plate 5 and the second connecting shaft 10 are fixedly connected by the second set screw 7, such as... Figure 1 and Figure 2 As shown, the first cover plate 5 can be removed by rotating and disassembling the second set screw 7.

[0029] Working principle: When using the infrared temperature measurement window and adjusting the installation status of the second cover plate 6 and the first cover plate 5, when installing the second cover plate 6, the first connecting shaft 9 corresponding to the second cover plate 6 is slidably inserted into the reserved cavity 12. During the insertion process, the first connecting shaft 9 is connected to the second connecting shaft 10 through the second recessed cavity 16 and the first recessed cavity 15 through the slot. When installing the first cover plate 5, the second set screw 7 is inserted through the first cover plate 5 and embedded into the second connecting shaft 10 to complete the fixation. Through the above fixation method, one of the first cover plate 5 and the second cover plate 6 can be fixed. When one rotates, the first connecting shaft 9 and the second connecting shaft 10 can drive the other to rotate. When the second cover plate 6 and the first cover plate 5 installed at both ends of the base 1 are fixed, the first set screw 4 is rotated through the fixing hole 3 and installed into the base 1. As the first set screw 4 continues to rotate, the first set screw 4 is embedded in the first embedding cavity 13 inside the first connecting shaft 9 and in the second embedding cavity 14 inside the second connecting shaft 10. The first connecting shaft 9 and the second connecting shaft 10 are fixed by the compression of the first set screw 4.
