Description

Technical Field

[0001] The utility model relates to the field of infrared temperature measurement windows, and specifically relates to an infrared temperature measurement window with double protection. Background Technique

[0002] An infrared temperature measurement window refers to a specific area or device that allows an infrared temperature measurement instrument to perform non-contact temperature measurement on a target object through this window. This window is usually made of special materials to ensure that infrared radiation can effectively penetrate and reduce heat loss, thereby ensuring the accuracy of temperature measurement. Infrared temperature measurement windows are commonly used in various scenarios where precise temperature measurement is required without affecting the target object or the environment;

[0003] The Chinese patent with the publication number CN208238949U discloses a rotary explosion-proof infrared temperature measurement window with a power-on checking function, including a limiting device composed of a limiting left elastic piece, spring A, fixing plate A, limiting right elastic piece, spring B, and fixing plate B. The limiting left elastic piece and the fixing plate A are fixed on one side wall of the arc groove. A spring A is fixed between the bent part of the limiting left elastic piece and the fixing plate A. The limiting ring A and the limiting ring B slide into the arc plate. The restoration of the deformation of spring A and spring B plays a role in supporting the limiting ring A and the limiting ring B to fix the window cover and the explosion-proof cover. When it needs to be opened, rotate the window cover, and spring A and spring B deform again. The limiting ring A and the limiting ring B slide out of the arc groove for opening. It is simple to use, avoids errors in temperature measurement, and has strong explosion-proof function.

Specific implementation manner

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] In order to solve the problem that the existing protective covers are located on both sides of the translucent crystal, when the infrared temperature measurement window is impacted, it can only be carried by the two protective covers, and the anti-impact ability is weak. The following technical solutions are provided in this embodiment:

[0020] An infrared temperature measurement window with double-layer protection includes a base 1. A translucent crystal 6 is arranged in the middle inside the base 1. As Figure 1 and Figure 2 shown, an inner protective cover 7 is arranged on one side outside the translucent crystal 6, and an outer protective cover 8 is arranged on the other side outside the translucent crystal 6. During actual use, the inner protective cover 7 and the outer protective cover 8 wrap and protect the translucent crystal 6 in the middle position;

[0021] In this embodiment, the inner protective cover 7 and the outer protective cover 8 are fixedly connected through a connecting shaft 9, and the outside of the connecting shaft 9 is rotationally connected to the inside of the base 1. As Figure 2 shown, the connecting shaft 9 is located at the lower end of the translucent crystal 6. Through the through connection of the connecting shaft 9, the inner protective cover 7 and the outer protective cover 8 at both ends can be uniformly driven and rotated;

[0022] In this embodiment, a reinforcement frame 2 is arranged on one side outside the outer protective cover 8. A concave second connection groove 14 is arranged on the side of the inside of the reinforcement frame 2 facing the outer protective cover 8. As Figure 2 and Figure 3 shown, when the reinforcement frame 2 rotates and wraps around the outside of the outer protective cover 8, the reinforcement frame 2 will cause the outer protective cover 8 to be embedded inside the second connection groove 14, and the second connection groove 14 is connected to the external card slot of the outer protective cover 8;

[0023] In this embodiment, a second thread wall 13 is arranged around the side of the base 1 facing the reinforcement frame 2, and a first thread wall 12 is arranged around the side of the inside of the reinforcement frame 2 facing the second thread wall 13. As Figure 3As shown, the outer part of the first threaded wall 12 is in threaded fit with the outer part of the second threaded wall 13. Through the threaded fit, the reinforcement frame 2 can be fixed to one side outside the base 1. By fixing the reinforcement frame 2 through the threaded fit, the reinforcement frame 2 and the outer protective cover 8 are combined to form a double-layer protection, preventing the impact force from extending outward after the transparent crystal 6 is broken by the impact force;

[0024] In this embodiment, a first connection groove 10 is provided around the surface of the reinforcement frame 2 facing the base 1, and the first connection groove 10 is recessed inside the base 1. A reinforcement ring 11 is provided around the inside of the first connection groove 10. As Figure 3 shown, the reinforcement ring 11 is welded and fixed to the reinforcement frame 2. The reinforcement ring 11 will be embedded inside the first connection groove 10 as the reinforcement frame 2 rotates. The circumferentially distributed reinforcement rings 11 can prevent the reinforcement frame 2 from bending and improve the further impact resistance of the reinforcement frame 2;

[0025] In this embodiment, a recessed ring 4 is provided around the outside of the reinforcement frame 2. As Figure 1 and Figure 3 shown, a protruding protective strip 5 is provided around the inside of the recessed ring 4. The protective strip 5 and the reinforcement frame 2 are of an integral structure. The protruding protective strip 5 facilitates the user to manually twist the reinforcement frame 2, facilitating the rotational installation and disassembly of the reinforcement frame 2;

[0026] In this embodiment, grounding conduction test terminals 3 are provided on both sides at the front end of the reinforcement frame 2. As Figure 1 and Figure 2 shown, the grounding conduction test terminals 3 can be installed on one side outside the base 1 through the reinforcement frame 2. The user can perform a grounding conduction test on the infrared temperature measurement window through the grounding conduction test terminals 3 outside.

[0027] Working principle: When using the infrared temperature measurement window, the inner protective cover 7 and the outer protective cover 8 are driven to reset and wrap around both sides of the transparent crystal 6 while being connected by the connecting shaft 9. After wrapping both sides, the reinforcement frame 2 rotates at the position of the second threaded wall 13 outside the base 1 through the first threaded wall 12. As the reinforcement frame 2 continues to rotate, the reinforcement frame 2 moves towards the outer protective cover 8. During the movement, the outer protective cover 8 is embedded inside the second connection groove 14 inside the reinforcement frame 2. At the same time of embedding, the reinforcement frame 2 will be embedded inside the first connection groove 10 through the reinforcement ring 11, and the reinforcement frame 2 and the outer protective cover 8 can form a double-layer protection structure.
