Technical Field

[0001] This utility model relates to the technical field of portable centering test structures, specifically a portable centering test structure. Background Technology

[0002] Lens centering test is an important process for measuring and correcting the alignment of the lens's optical axis with its geometric axis (such as the outer symmetry axis), which directly affects the imaging quality of the optical system. It uses parallel light projected onto the focal plane to form a reticle image, and the error is determined by analyzing the position of the light spot. This method cannot directly locate the specific lens surface error, but it can detect the overall alignment accuracy.

[0003] Currently, traditional lens centering test structures generally consist of two parts: a display and a test unit. The test unit collects data information from the lens and transmits it to the display for display. However, existing test structures are generally installed on a desktop, with the test unit and the display being two separate entities connected by a cable, making them inconvenient to carry and transport.

[0004] To address this, we propose a portable centering test structure. Utility Model Content

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0021] Example 1: Please see Figure 1 - Figure 6 This is the first embodiment of the present utility model. This utility model provides a portable centering test structure, including: a shell 1, a top cover 2 rotatably connected to the end of the shell 1, a lock body 3 provided between the top cover 2 and the shell 1, a test body 4 installed inside the shell 1, a display mechanism 5 provided on one side of the test body 4, and a moving part 6 installed at the bottom of the test body 4, the moving part 6 being used to move the test body 4 upward to the end of the shell 1.

[0022] Support legs 31 are fixedly connected to the bottom corners of the outer shell 1. When in use, the outer shell 1 can act as a support platform. The design of the support legs 31 can improve the stability of the test body 4 during use.

[0023] In addition, a handle 32 is fixedly connected to the end of the top cover 2, which makes it easy to lift the outer shell 1 and thus facilitates the transport of the carrying device.

[0024] It should be noted that the test body 4 is provided inside the outer casing 1 and a display mechanism 5 is connected to the test body 4. When the test body 4 is needed, the test body 4 is pushed to the end of the outer casing 1 by the moving part 6 connected to the test body 4 inside the outer casing 1. This facilitates use. After use, the moving part 6 moves in the opposite direction to move the test body 4 into the outer casing 1 and seals it with the top cover 2. This facilitates the transfer of the test structure.

[0025] In the embodiments of this utility model, please refer to Figure 2 - Figure 4 The movable component 6 shown in the figure includes a movable plate 7 fixed to the bottom of the test body 4. The movable plate 7 is slidably connected to the outer shell 1, and a threaded block 8 is fixedly connected to the movable plate 7. A threaded rod 9 that is rotatably connected to the outer shell 1 is threadedly connected to the threaded block 8. A drive component 10 is installed at the end of the threaded rod 9.

[0026] In the embodiments of this utility model, please refer to Figure 2 - Figure 4The driving component 10 shown in the figure includes a fixed frame 11 fixed inside the housing 1. A motor 12 is fixedly connected to the fixed frame 11. A drive shaft 13 is fixedly connected to the output end of the motor 12. A transmission component 14 connected to the threaded rod 9 is installed at the end of the drive shaft 13.

[0027] In the embodiments of this utility model, please refer to Figure 2 - Figure 4 The transmission component 14 shown in the figure includes a first bevel gear 15 fixedly connected to the drive shaft 13, a second bevel gear 16 meshing with the outer side of the first bevel gear 15, and a transmission shaft 17 fixedly connected to the threaded rod 9 at the axis of the second bevel gear 16.

[0028] It should be noted that when using the test body 4, the control motor 12 is started. After the motor 12 starts, it will drive the drive shaft 13 to rotate. The rotation of the drive shaft 13 will drive the first bevel gear 15 to rotate. The rotation of the first bevel gear 15 will drive the second bevel gear 16 to rotate. The rotation of the second bevel gear 16 will cause the transmission shaft 17 to drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 will drive the moving plate 7 to move upward. The upward movement of the moving plate 7 will drive the test body 4 to move upward, thereby moving the test body 4 to the end of the outer shell 1 for easy use.

[0029] Furthermore, after use, by controlling the motor 12 to reverse, the drive shaft 13 will drive the first bevel gear 15 to reverse. The reversal of the first bevel gear 15 will cause the second bevel gear 16 to drive the transmission shaft 17 to reverse, which in turn will cause the threaded rod 9 to reverse. The reversal of the threaded rod 9 will cause the moving plate 7 to move down, which will then drive the test body 4 to move down into the outer shell 1. After that, the top cover 2 will be closed and locked by the lock body 3.

[0030] Example 2: Please see Figure 1 - Figure 6 This is the second embodiment of the present invention. In the embodiments of this utility model, please refer to Figure 3 and Figure 5 The display mechanism 5 shown in the figure includes a rotating shaft 18 rotatably connected to the test body 4, a fixed seat 19 rotatably connected to the rotating shaft 18 and fixedly connected to the test body 4, a fixed sleeve 20 fixedly connected to the outer side of the rotating shaft 18, a support plate 21 fixedly connected to the fixed sleeve 20, a support block 22 fixedly connected to the support plate 21, a display 23 provided at the end of the support block 22, and a fixing member 24 provided at the end of the display 23.

[0031] The support plate 21 has several sets of heat dissipation holes 30 to facilitate heat dissipation for the display 23.

[0032] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The fastener 24 shown in the figure includes a connecting plate 25 fixedly connected to the support plate 21. A sliding column 26 is slidably connected to the connecting plate 25. A sliding plate 27 is fixedly connected to the end of the sliding column 26. Multiple sets of limiting blocks 28 are fixedly connected to the bottom end of the sliding plate 27. A spring 29 sleeved on the outer side of the sliding column 26 is fixedly connected between the sliding plate 27 and the connecting plate 25.

[0033] It should be noted that during use, the display mechanism 5 and the test body 4 are moved together to the end of the outer shell 1. At this time, the support plate 21 is rotated, which causes the support plate 21 to drive the display 23 to rotate, so that the display 23 can be unfolded, making it easier to view the display 23.

[0034] Furthermore, after use, the support plate 21 and the display 23 are rotated in the opposite direction, causing the support plate 21 to fold, which facilitates the display mechanism 5 and the test body 4 to slide in the opposite direction into the housing 1.

[0035] Furthermore, the fastener 24 facilitates the disassembly and installation of the monitor 23, thereby making it easier to replace the monitor 23.

[0036] Working principle: When using the test body 4, the top cover 2 is opened, and then the motor 12 is started. After the motor 12 starts, it will drive the drive shaft 13 to rotate. The rotation of the drive shaft 13 will drive the first bevel gear 15 to rotate. The rotation of the first bevel gear 15 will drive the second bevel gear 16 to rotate. The rotation of the second bevel gear 16 will cause the transmission shaft 17 to drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 will drive the moving plate 7 to move upward. The upward movement of the moving plate 7 will drive the test body 4 to move upward, thereby moving the test body 4 to the end of the outer shell 1 for easy use. During use, the display mechanism 5 and the test body 4 are moved together to the end of the outer shell 1. At this time, the support plate 21 is rotated, which causes the support plate 21 to drive the display 23 to rotate, so that the display 23 can be unfolded, making it easier to view the display 23. Furthermore, after use, by controlling the motor 12 to reverse, the drive shaft 13 will drive the first bevel gear 15 to reverse. The reversal of the first bevel gear 15 will cause the second bevel gear 16 to drive the transmission shaft 17 to reverse, which in turn will cause the threaded rod 9 to reverse. The reversal of the threaded rod 9 will cause the moving plate 7 to move down, which will then drive the test body 4 to move down into the outer shell 1. After that, the top cover 2 will be closed and locked by the lock body 3. The handle 32 will facilitate lifting and carrying. After use, the support plate 21 and the display 23 are rotated in the opposite direction, so that the support plate 21 is folded, which makes it easier for the display mechanism 5 and the test body 4 to slide in the opposite direction into the outer shell 1. It is worth noting that the sliding plate 27 and the limiting block 28 can move freely through the action of the sliding column 26 and the spring 29, which facilitates the disassembly and installation of the display 23, and thus facilitates the replacement and maintenance of the display 23.
