[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, an infrared photoelectric probe testing device includes a housing 2, a cover plate 1 fixedly connected to the upper end of the housing 2, a door 4 rotatably connected to the upper front end of the housing 2, two observation windows 3 symmetrically opened at the left and right ends of the housing 2, a vibration mechanism 6 fixedly connected to the middle of the bottom wall of the inner cavity of the housing 2, a fixing mechanism 5 fixedly connected to the upper end of the vibration mechanism 6, a temperature control mechanism 7 fixedly connected to the rear wall of the inner cavity of the housing 2, and several halogen lamps 8 fixedly connected to the inner surface side wall of the cover plate 1.

[0023] In the specific implementation process of this utility model, firstly, the door 4 is opened and the probe is placed inside the fixing mechanism 5. The fixing mechanism 5 can fix the probe in place. Then, the door 4 is closed and the halogen lamp 8 is turned on to conduct a light illumination test on the probe. At the same time, the internal drive structure of the vibration mechanism 6 is activated. The vibration mechanism 6 causes the fixing mechanism 5 to vibrate, thereby simulating a vibration environment. Then, the internal structure of the temperature control mechanism 7 is activated to control the temperature in the inner cavity of the chamber 2, so that it can simulate the environment of different temperatures to test the probe. During the test, the staff can observe the test effect on the probe through the observation window 3.

[0024] Specifically, in order to achieve the goal of fixing the probe during testing, refer to Figure 4In this solution, the fixing mechanism 5 includes a fixing box 51, which is fixedly connected to the middle of the upper end of the base plate 63. The inner cavity of the fixing box 51 has a groove 53. The left and right walls of the groove 53 are fixedly connected to spring pieces 54. The ends of the two spring pieces 54 that are close to each other are fixedly connected to clamping blocks 55. The middle of the upper end of the fixing box 51 is slidably connected to a probe 52.

[0025] Furthermore, the upper ends of both clamping blocks 55 are inclined.

[0026] In the above process, the probe 52 is directly inserted downward from the top of the fixing box 51 by opening the door 4, so that the bottom of the probe 52 presses down and the two clamping blocks 55 are dispersed to both sides. Then, the probe 52 is clamped and fixed by the two spring pieces 54 pressing the clamping blocks 55.

[0027] Specifically, in order to generate vibration during testing, refer to Figure 3 In this scheme, the vibration mechanism 6 includes several springs 62 and two support blocks 67. The several springs 62 are respectively fixedly connected to the four corners of the bottom wall of the inner cavity of the box 2. The upper ends of the several springs 62 are jointly fixedly connected to a base plate 63. The two support blocks 67 are respectively fixedly connected to the front and rear sides of the middle of the bottom wall of the inner cavity of the box 2. The upper part of the opposite surfaces of the two support blocks 67 is rotatably connected to a rotating plate 68. The upper right side of the two rotating plates 68 is fixedly connected to an inclined block 69. The right side of the two rotating plates 68 that are close to each other is jointly fixedly connected to a sliding column 691. The outer surface of the sliding column 691 is slidably connected to a sliding ring 66.

[0028] Furthermore, a motor 61 is fixedly connected to the right side of the bottom wall of the housing 2, and a support block 64 is fixedly connected to the right side of the middle part of the bottom wall of the housing 2. A turntable 65 is rotatably connected to the upper left end of the support block 64. The right side of the slip ring 66 is slidably connected to the side of the turntable 65 away from its axis. The output end of the motor 61 is fixedly connected to the right end of the turntable 65 through a coupling.

[0029] In the above process, the starter motor 61 drives the turntable 65 to rotate. The rotation of the turntable 65 causes the slip ring 66 to rotate around the axis of the rotating end of the motor 61. Then, through the set sliding column 691, the left side of the slip ring 66 slides on the surface of the sliding column 691 while the turntable 65 is rotating. Then, through the set support block 67, the right side of the rotating plate 68 can be driven to move up and down, so that the inclined block 69 contacts the lower end of the base plate 63. Then, through the action of the spring 62, the base plate 63 vibrates.

[0030] The specific installation method, circuit connection method, and control method of the motor 61 mentioned above are all conventional designs, and this utility model will not elaborate on them in detail. In the implementation process, it is only necessary to be able to rotate the turntable 65.

[0031] Specifically, in order to simulate different temperatures for testing the probe 52, refer to Figure 5 In this solution, the temperature control mechanism 7 includes a C-shaped box 71, which is fixedly connected to the lower side of the rear wall of the inner cavity of the box 2. A circulation pipe 72 is fixedly connected to the upper part of the inner cavity of the C-shaped box 71, a resistance wire 73 is fixedly connected to the lower part of the inner cavity of the C-shaped box 71, a heating box 74 is fixedly connected to the front right side of the bottom wall of the inner cavity of the box 2, a cooling box 75 is fixedly connected to the middle right side of the bottom wall of the box 2, and a water pump 76 is fixedly connected to the rear right side of the bottom wall of the box 2.

[0032] Furthermore, the output and input ends of the heating box 74 are fixedly connected to the input and output ends of the resistance wire 73, respectively; the input end of the cooling box 75 is fixedly connected to the output end of the circulation pipe 72; and the input and output ends of the water pump 76 are fixedly connected to the output end of the cooling box 75 and the input end of the circulation pipe 72, respectively.

[0033] In the above, when it is necessary to perform a high-temperature test on the probe 52, the heating box 74 is activated to generate heat, which is then transferred to the inside of the resistance wire 73. The heat generated by the resistance wire 73 is then transferred to the inside of the box 2 through the surface of the C-shaped box 71, thereby achieving the purpose of heating the inner cavity of the box 2.

[0034] When a low-temperature test is required on the probe 52, the coolant inside the circulation pipe 72 is cooled by starting the cooling box 75 and the water pump 76. Then, the coolant is circulated inside the circulation pipe 72 by the action of the water pump 76 to achieve the purpose of cooling. Then, the cold air emitted by the circulation pipe 72 is transferred to the inner cavity of the box 2 through the surface of the C-shaped box 71 to achieve the purpose of lowering the temperature of the inner cavity of the box 2.

[0035] The specific installation method, circuit connection method, and control method of the water pump 76 mentioned above are all conventional designs, and this utility model will not elaborate on them in detail. In the implementation process, it is only necessary to circulate the coolant in the inner cavity of the circulation pipe 72.

[0036] It should be noted that the specific installation method, circuit connection method and control method of the heating box 74 and the cooling box 75 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0037] The working principle of this utility model is as follows: First, open the door 4 and place the probe inside the fixing mechanism 5. The fixing mechanism 5 can fix the probe in place. Then, close the door 4 and turn on the halogen lamp 8 to conduct a light illumination test on the probe. At the same time, start the internal drive structure of the vibration mechanism 6. The vibration mechanism 6 causes the fixing mechanism 5 to vibrate, thereby simulating a vibration environment. Then, start the internal structure of the temperature control mechanism 7 to control the temperature in the inner cavity of the chamber 2, so that it can simulate the environment of different temperatures to test the probe. During the test, the staff can observe the test effect on the probe through the observation window 3.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
