Abstract
Description
Technical Field
[0001] This utility model relates to the field of infrared detector Dewar component technology, and in particular to a cooling detector fixing structure. Background Technology
[0002] Cooled infrared detectors generally refer to infrared detectors made using the photonic effect between semiconductor materials. The photoelectric effect requires the semiconductor to be cooled to a relatively low temperature (typically 77K) to achieve detection functionality; therefore, infrared systems require a cooling mechanism for operation. Separately cooled detectors are coupled separately to the cooling system. The detector's mounting structure needs to be designed separately based on the given installation space. The detector assembly is formed by combining the detector with the mechanical mounting structure. The design of the detector's mounting structure must comprehensively consider technical characteristics such as meeting the product's positioning requirements, stability, and ease of assembly.
[0003] Existing technologies generally cannot effectively fix detectors. Therefore, a reliable detector fixing structure is needed. Utility Model Content

The cooling detector fixing structure of this invention can limit the detector in multiple directions and effectively fix the detector.
[0005] This utility model provides a cooling detector fixing structure, including a fixing frame, a circular pressure plate, and a square pressure plate. The fixing frame has a circular fixing part and a square fixing part on its upper side. The detector has a cylindrical part and a square part. The circular pressure plate is detachably connected to the circular fixing part, forming a circular hole for fixing the cylindrical part on the detector. The square pressure plate is detachably connected to the square fixing part, forming a square hole for fixing the square part on the detector.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0024] Example 1:
[0025] This embodiment provides a cooling detector fixing structure, such as... Figures 1-4 As shown, the detector includes a mounting bracket 2, a circular pressure plate 3, and a square pressure plate 4. The mounting bracket 2 has a circular fixing part 21 and a square fixing part 22 on its upper side, and the detector 1 has a cylindrical part 11 and a square part 12. The circular pressure plate 3 is detachably connected to the circular fixing part 21, forming a circular hole 7 for fixing the cylindrical part 11 on the detector 1. The square pressure plate is detachably connected to the square fixing part 22, forming a square hole 8 for fixing the square part 12 on the detector 1. The axis of the circular hole 7 and the center line of the square hole 8 are collinear. Limiting components are provided on both sides of the square hole 8, which restrict the movement of the square part 12 on the detector 1 along its axis.
[0026] like Figure 1 and Figure 3 As shown, detector 1 has a Dewar 14 and a compressor 15. The Dewar 14 is located at the front end of the detector, and the compressor 15 is located at the rear end of the detector. Between the Dewar 14 and the compressor 15, there is a cylindrical portion 11 and a square portion 12. The cylindrical portion 11 is located in front of the square portion 12. The Dewar 14, compressor 15, cylindrical portion 11, and square portion 12 are coaxially arranged. Detector 1 has a valve 13, which is located on the centerline of the square portion 12. The structure of detector 1 is a conventional structure.
[0027] In this embodiment, the cooling detector fixing structure is used by placing the detector 1 on the fixing frame 2, with the cylindrical part 11 correspondingly set on the circular fixing part 21 and the square part 12 correspondingly set on the square fixing part 22. The valve 13 is horizontal and centered. Then, the circular pressure plate 3 is connected to the circular fixing part 21, and the square pressure plate 4 is connected to the square fixing part 22. Due to the limiting effect of the square hole 8 formed by the connection between the square pressure plate 4 and the square fixing part 22 on the square part 12 on the detector 1, the detector can be effectively prevented from rotating and moving horizontally, so that the valve of the detector is kept horizontal and centered. The axis of the circular hole 7 and the center line of the square hole 8 are on the same straight line, so that the front circular end face of the detector is concentric with the other components of the product. By setting the limiting component, the movement of the detector 1 along its axis can be restricted, thereby limiting the detector in multiple directions and effectively fixing the detector 1.
[0028] As a preferred embodiment, such as Figure 3 and Figure 4 As shown, the limiting assembly includes a first limiting block 51 and a second limiting block 52. The first limiting block 51 is disposed on the upper side of the fixing frame 2, and the second limiting block 52 is disposed on the square pressure plate 4. The first limiting block 51 and the second limiting block 52 are respectively located on the front and rear sides of the square part 12 of the detector. The first limiting block 51 and the second limiting block 52 clamp the square part 12 between the upper and lower sides of the square part 12 to limit the square part 12, thereby limiting and fixing the detector on the axis and preventing relative movement in the axial x-axis between the detector and the fixing structure.
[0029] As a preferred embodiment, such as Figure 4 As shown, the circular pressure plate 3 is arc-shaped, and its left and right sides are respectively connected to the circular fixing part 21 by bolts. The circular pressure plate 3 is semi-circular, and the corresponding circular fixing part 21 is also semi-circular, to facilitate the installation of the cylindrical part 11 of the detector. The left and right sides of the circular pressure plate 3 are respectively connected to the circular fixing part 21 by bolts, so that the circular pressure plate 3 is pressed tightly on the cylindrical part 11, which is convenient for disassembly and assembly and is firmly fixed.
[0030] In a preferred embodiment, the circular fixing part 21 is disposed on the front side of the square fixing part 22, and the two are spaced apart. The positions of the circular fixing part 21 and the square fixing part 22 are set according to the positional relationship and spacing between the cylindrical part 11 and the square part 12 on the detector, so that the circular fixing part 21 is adapted to the cylindrical part 11 and the square fixing part 22 is adapted to the square part 12.
[0031] In a preferred embodiment, the cooling detector fixing structure of this embodiment further includes a fixing plate 6. Multiple connecting feet 23 are provided at the bottom of the fixing frame 2, and the connecting feet 23 are connected to the fixing plate 6 via connectors. The connecting feet 23 provide support for the fixing frame 2. The connecting feet 23 have fixing holes and are connected to the fixing plate 6 via the fixing holes and connectors. The fixing holes are elongated holes along the axial direction.
[0032] As a preferred embodiment, such as Figure 1 As shown, the fixing plate 6 has multiple connecting holes 61 arranged along its length. The connecting feet 23 can be connected to different connecting holes 61, and the fixing bracket 2 is adjustablely connected to the fixing plate 6. The distance between two adjacent connecting holes 61 is equal to the distance between the fixing holes on the two connecting feet 23 on the same side of the fixing bracket 2.
[0033] By adjusting the mounting bracket 2 to the mounting plate 6, the detector can be adjusted relative to the mounting device in the axial x direction, so that the detector can be adjusted to meet the product's usage requirements and improve the flexibility of use.
[0034] In one preferred embodiment, the connecting feet 23 include four, with two connecting feet 23 respectively provided on the left and right sides of the fixing frame 2, and the straight line of the two connecting feet 23 on the same side is parallel to the axis of the detector. Preferably, the fixing plate 6 has two rows of connecting holes 61, and the length direction of the fixing plate 6 is parallel to the axis of the detector.
[0035] In this embodiment, the detector is assembled onto the mounting plate 6 via four elongated holes below the mounting bracket 2, allowing for axial adjustment of the detector. After the detector assembly is adjusted to meet product usage requirements, it is secured to the mounting plate 6 with four fasteners, ensuring reliable fixation between the detector assembly and the product. Connecting screws are fixed to the mounting plate 6 from top to bottom using tools, with no other structural interference, facilitating assembly by workers.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
