Description

Technical Field

[0001] The utility model specifically relates to a splicing protection structure for an outdoor infrared security thermal imaging lens. Background Technique

[0002] With the development of science and technology, infrared imaging technology has been widely used in the fields of national defense, industry, medical treatment, etc. Infrared detection has a certain ability to penetrate smoke, fog, haze, etc., and is not affected by strong light and flash interference. The infrared lens products formed by using infrared imaging technology can realize the recognition and tracking of dynamic targets at a long distance.

[0003] At present, after the outdoor infrared security thermal imaging lens is used for a long time, a large amount of dust and various impurities will adhere to its outer surface. However, since the infrared security thermal imaging lens is fixed and cannot be disassembled for cleaning, after a long time of accumulation, the impurities will enter the inside through the welding seams on the surface of the infrared security thermal imaging lens, affecting the service life of the infrared security thermal imaging lens. Content of the Utility Model

[0004] The purpose of the utility model is to provide a splicing protection structure for an outdoor infrared security thermal imaging lens to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a splicing protection structure for an outdoor infrared security thermal imaging lens, including an upper end cover, a lower end cover, a thermal imaging lens body, a sliding component and a limiting component. The upper end cover and the lower end cover are respectively arranged on the upper and lower sides of the thermal imaging lens body. The upper end cover and the lower end cover are spliced through the sliding component to form an independent cavity for protecting the thermal imaging lens body.

[0006] Among them, the limiting component is used to fix the spliced upper end cover and lower end cover.

[0007] Preferably, the sliding component includes chutes opened on both sides inside the lower end cover. The chutes are open toward the insertion end side of the lower end cover, and the other side of the chutes is closed.

[0008] Preferably, sliding blocks adapted to the chutes are arranged on both outer sides of the upper end cover.

[0009] Preferably, a baffle is arranged on the side of the lower end cover away from the insertion end, and a through hole for inserting a power supply cable is centrally opened on the surface of the baffle.

[0010] Preferably, the limiting component includes a fixing block arranged at the rear side of the upper end cover. An open-ended groove is inwardly opened on the surface of the fixing block, and springs are arranged on both the upper and lower sides inside the groove.

[0011] Preferably, two springs are provided. Moving plates are provided at one end of the two springs close to each other. One end of the moving plate extending out of the groove through the opening is connected with a limiting plate.

[0012] Preferably, limiting grooves are formed on the surface of the baffle.

[0013] The technical effects and advantages of the present utility model: For the splicing protection structure of the outdoor infrared security thermal imaging lens, after connecting the upper end cover and the thermal imaging lens body through the positioning bolts, the slider is aligned with the sliding groove. As the slider slides along the length direction of the sliding groove, the upper end cover slides within the lower end cover, and an independent cavity for protecting the thermal imaging lens body is formed between the upper end cover and the lower end cover. And when the upper end cover slides to the end of the lower end cover, by pressing the two limiting plates, the two limiting plates approach each other. When the fixing block penetrates through the limiting groove, the spring deforms, pops out the two limiting plates, and clamps them on both sides of the limiting groove to complete the fixation of the upper end cover and the lower end cover.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] For the purpose of facilitating the extension of the service life of the thermal imaging lens body 3, with reference to Figure 1 、 Figure 2 and Figure 3As shown, it includes an upper end cover 1, a lower end cover 2, a thermal imaging lens body 3, a sliding assembly and a limiting assembly. The upper end cover 1 and the lower end cover 2 are respectively arranged on the upper and lower sides of the thermal imaging lens body 3. Between the upper end cover 1 and the lower end cover 2, an independent cavity for protecting the thermal imaging lens body 3 is formed by splicing through the sliding assembly. Among them, the limiting assembly is used to fix the spliced upper end cover 1 and lower end cover 2. After connecting the upper end cover 1 to the thermal imaging lens body 3 through a positioning bolt, the slider 5 is aligned with the chute 4. As the slider 5 slides along the length direction of the chute 4, the upper end cover 1 slides within the lower end cover 2, and an independent cavity for protecting the thermal imaging lens body 3 is formed between the upper end cover 1 and the lower end cover 2. And when the upper end cover 1 slides to the end of the lower end cover 2, by pressing the two limiting plates 12, the two limiting plates 12 approach each other. When the fixed block 8 penetrates through the limiting groove 13, the spring 10 deforms, and the two limiting plates 12 are ejected and clamped on both sides of the limiting groove 13 to complete the fixation of the upper end cover 1 and the lower end cover 2. Through the settings of the upper end cover 1 and the lower end cover 2, it is possible to prevent dust and impurities from directly falling onto the surface of the thermal imaging lens body 3, and it is convenient to disassemble the upper end cover 1 and the lower end cover 2 from the thermal imaging lens body 3, so as to complete the cleaning.

[0021] In order to improve the stability after the connection of the upper end cover 1 and the lower end cover 2, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the sliding assembly includes chutes 4 opened on both sides inside the lower end cover 2. The chutes 4 are open toward the insertion end side of the lower end cover 2, and the other side of the chutes 4 is closed. When the slider 5 slides to the end of the chute 4, the fixed block 8 can just be inserted into the limiting groove 13. Sliders 5 adapted to the chutes 4 are arranged on both outer sides of the upper end cover 1. By sliding the sliders 5 along the length direction of the chutes 4, the upper end cover 1 and the lower end cover 2 can be spliced to form an independent cavity for placing the thermal imaging lens body 3. A hole groove is opened on the upper surface of the upper end cover 1, and a positioning bolt is inserted through the hole groove, and the positioning bolt extends into the thermal imaging lens body 3, so as to realize the connection between the upper end cover 1 and the thermal imaging lens body 3. A baffle 6 is arranged on the side of the lower end cover 2 away from the insertion end. A through hole 7 for inserting a power cable is centrally opened on the surface of the baffle 6. By fixing the upper end cover 1 with the baffle 6, the stability after the connection of the upper end cover 1 and the lower end cover 2 is improved.

[0022] Further, the limiting component includes a fixing block 8 arranged at the rear side of the upper end cover 1. An inwardly open groove 9 is formed on the surface of the fixing block 8. Springs 10 are arranged on both the upper and lower sides inside the groove 9. Two springs 10 are provided. One end of each of the two springs 10 close to each other is provided with a moving plate 11. One end of the moving plate 11 extends out of the groove 9 through the opening and is connected with a limiting plate 12. A limiting groove 13 is formed on the surface of the baffle 6. When the fixing block 8 is inserted into the limiting groove 13, press the two limiting plates 12 to drive the two moving plates 11 to approach each other, so that the springs 10 are stretched. As the fixing block 8 is inserted into the groove 9, the limiting plate 12 loses the extrusion force, the springs 10 deform, and the reaction force acts on the limiting plate 12, causing the two moving plates 11 to move away from each other, driving the two limiting plates 12 to move away from each other, so as to be clamped outside the limiting groove 13, realizing the fixation of the upper end cover 1 and the lower end cover 2.

[0023] During use, first connect the upper end cover 1 with the thermal imaging lens body 3 using positioning bolts. Then align the slider 5 with the sliding groove 4. As the slider 5 slides along the length direction of the sliding groove 4, the upper end cover 1 slides inside the lower end cover 2, forming an independent cavity for protecting the thermal imaging lens body 3 between the upper end cover 1 and the lower end cover 2. And when the upper end cover 1 slides to the end of the lower end cover 2, press the two limiting plates 12 to make the two limiting plates 12 approach each other. When the fixing block 8 penetrates through the limiting groove 13, the springs 10 deform, eject the two limiting plates 12, and clamp them on both sides of the limiting groove 13, completing the fixation of the upper end cover 1 and the lower end cover 2. Through the setting of the upper end cover 1 and the lower end cover 2, it is possible to prevent dust and impurities from directly falling onto the surface of the thermal imaging lens body 3, and the upper end cover 1 and the lower end cover 2 can be disassembled from the thermal imaging lens body 3.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
