Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to a testing device for an infrared camera. Background Technology

[0002] An infrared camera is a device that can detect and capture the infrared radiation of an object and convert it into a visible image. It does not rely on visible light and can work even in complete darkness, smoke, dust and other environments. It is widely used in security, night vision, industrial inspection, medical and other fields.

[0003] Infrared cameras require testing after production to ensure stable operation in various scenarios. Due to the significant size differences between cameras of different dimensions, existing testing devices cannot fine-tune the camera angle after fixing it in place. This results in the target surface not falling completely into the camera's field of view during testing. Therefore, we provide a testing device for infrared cameras. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for infrared cameras to solve the problems described in the background section.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a testing device for an infrared camera, including a base; a support plate is slidably disposed on the upper surface of the base, and an angle adjustment component is rotatably disposed on the upper surface of the support plate;

[0006] The angle adjustment assembly includes a first support plate, a second support plate rotatably mounted on the upper surface of the first support plate, two semicircular blocks symmetrically fixed on the upper surface of the second support plate, a connecting rod fixedly connected between the two semicircular blocks, a U-shaped plate rotatably mounted on the outer wall of the two semicircular blocks, and a mounting base fixedly connected to the upper surface of the U-shaped plate.

[0007] The present invention is further configured such that two fixing rods are fixedly connected to the upper surface of the first bearing plate, and two arc-shaped grooves that cooperate with the fixing rods are opened on the upper surface of the second bearing plate, and a limit ring is threadedly connected to the outer wall of the fixing rod.

[0008] The present invention is further configured such that a worm gear is rotatably connected to the bottom of the U-shaped plate, a semi-circular worm wheel that meshes with the worm gear is fixedly connected to the outer wall of the connecting rod, and a motor that is connected to the worm gear is fixedly connected to the outer wall of the U-shaped plate.

[0009] The present invention is further configured such that the outer walls of the two semicircular blocks are provided with sliding grooves, and the interior of the sliding grooves is slidably connected to limit blocks, and the upper surface of the limit blocks is fixedly connected to a circular rod connected to the U-shaped plate.

[0010] The present invention is further configured such that a groove is formed on the upper surface of the base, a threaded rod is rotatably connected inside the groove, the threaded rod is threadedly connected to the bottom of the support plate, and a motor connected to the threaded rod is fixedly connected to the outer wall of the base.

[0011] This utility model has the following beneficial effects:

[0012] This invention enables the camera angle to be adjusted after installation by cooperating with the specific components of the angle adjustment assembly. This avoids the problem that the target surface cannot be completely within the camera's field of view during testing because the size of different infrared cameras makes it difficult to fine-tune the angle after the camera is fixed, such as the pitch angle or horizontal rotation.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 3 This utility model is a testing device for an infrared camera, including a base 1; a support plate 4 is slidably disposed on the upper surface of the base 1, and an angle adjustment component is rotatably disposed on the upper surface of the support plate 4; the angle adjustment component includes a first bearing plate 5, two fixing rods 15 are fixedly connected to the upper surface of the first bearing plate 5, and two arc-shaped grooves 14 are formed on the upper surface of the second bearing plate 6 to cooperate with the fixing rods 15. A limit ring 16 is threadedly connected to the outer wall of the fixing rods 15. A second bearing plate 6 is rotatably disposed on the upper surface of the first bearing plate 5, and two semi-circular blocks 7 are symmetrically fixed on the upper surface of the second bearing plate 6. A connecting rod 8 is fixedly connected between the two semicircular blocks 7. A U-shaped plate 13 is rotatably provided on the outer wall of the two semicircular blocks 7. A sliding groove 10 is opened on the outer wall of each of the two semicircular blocks 7. A limit block 11 is slidably connected inside the sliding groove 10. A circular rod 12 connected to the U-shaped plate 13 is fixedly connected to the upper surface of the limit block 11. A worm gear 19 is rotatably connected to the bottom of the U-shaped plate 13. A semicircular worm wheel 9 meshing with the worm gear 19 is fixedly connected to the outer wall of the connecting rod 8. A motor 17 connected to the worm gear 19 is fixedly connected to the outer wall of the U-shaped plate 13. A mounting base 18 is fixedly connected to the upper surface of the U-shaped plate 13.

[0022] First, at the bottom is the base 1, and on the base 1 is a sliding support plate 4, just like a drawer we usually push. The support plate 4 is equipped with an angle adjustment component, which is the core part. At the bottom is the first support plate 5, on which stand two fixing rods 15. The second support plate 6 above it can rotate around the first support plate 5. The second support plate 6 has two arc-shaped grooves 14, through which the fixing rods 15 pass. A limit ring 16 is screwed on the outside. After rotating to the appropriate angle, tighten the limiting ring 16 to fix the second bearing plate 6 in place and prevent it from moving around. Two semi-circular blocks 7 are also welded on the second bearing plate 6, with a connecting rod 8 in the middle. The outside of these two semi-circular blocks 7 are connected to the U-shaped plate 13, and the U-shaped plate 13 can rotate around the semi-circular blocks 7. The outer wall of the semi-circular blocks 7 has a sliding groove 10, which holds the limiting block 11. The circular rod 12 on the limiting block 11 is connected to the U-shaped plate 13, making the U-shaped plate 13 slide more stably. The most critical angle adjustment power comes from the first motor 17. The bottom of the U-shaped plate 13 is fitted with a worm gear 19, and a semi-circular worm wheel 9 is fixed on the connecting rod 8. The worm gear 19 and the semi-circular worm wheel 9 mesh together. When the external power source is connected to start the motor 17, the worm gear 19 rotates. When the worm gear 19 rotates, it completes the helical feed with the semi-circular worm wheel 9, which causes the U-shaped plate 13 to rotate up and down, adjusting the tilt angle of the camera. Finally, the mounting bracket 18 on the U-shaped plate 13 is used to fix the infrared camera, where the camera is installed.

[0023] Please see Figure 1 A groove 2 is provided on the upper surface of the base 1. A threaded rod 3 is rotatably connected inside the groove 2. The threaded rod 3 is threadedly connected to the bottom of the support plate 4. A motor 20 connected to the threaded rod 3 is fixedly connected to the outer wall of the base 1.

[0024] When connected to an external power source, motor 20 is started, which drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 causes the adjustment component on the support plate 4 to move linearly, changing the distance of the adjustment component so that the target image can more easily enter the camera's view. Motor 20 is controlled to rotate forward and backward by a microcontroller.

[0025] The operation process of this embodiment is as follows: First, the bottom is the base 1, and there is a sliding support plate 4 on the base 1, just like a drawer that we usually push. An angle adjustment component is installed on the support plate 4. This part is the core. The bottom is the first bearing plate 5, on which two fixing rods 15 stand. The second bearing plate 6 above can rotate around the first bearing plate 5. Two arc-shaped grooves 14 are opened on the second bearing plate 6, and the fixing rods 15 pass through the grooves. A limiting ring 16 is also screwed on the outside. After rotating to the appropriate angle, tighten the limiting ring 16 to fix the second bearing plate 6 in place and prevent it from moving around. Two semi-circular blocks 7 are also welded on the second bearing plate 6, with a connecting rod 8 in the middle. The outside of these two semi-circular blocks 7 are connected to the U-shaped plate 13, and the U-shaped plate 13 can rotate around the semi-circular blocks 7. The outer wall of the semi-circular blocks 7 has a sliding groove 10, which holds the limiting block 11. The circular rod 12 on the limiting block 11 is connected to the U-shaped plate 13, making the U-shaped plate 13 slide more stably. The most critical angle adjustment power comes from the first motor 17. The bottom of the U-shaped plate 13 is fitted with a worm gear 19, and a semi-circular worm wheel 9 is fixed on the connecting rod 8. The worm gear 19 and the semi-circular worm wheel 9 mesh together. When the external power source is connected to start the motor 17, the worm gear 19 rotates. When the worm gear 19 rotates, it completes the helical feed with the semi-circular worm wheel 9, which causes the U-shaped plate 13 to rotate up and down, adjusting the tilt angle of the camera. Finally, the mounting base 18 on the U-shaped plate 13 is used to fix the infrared camera. When the camera is mounted here, the external power source is connected to start the motor 20, which drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 causes the adjustment component on the support plate 4 to move linearly, changing the distance of the adjustment component, making it easier for the target image to enter the camera's view. The motor 20 is controlled to rotate forward and backward by a microcontroller.
