Technical Field

[0001] The utility model relates to the technical field of sensor testing, and particularly relates to a self-made sensor aging test rack. Background Technique

[0002] A sensor is an important means of information acquisition. Together with communication technology and computer technology, it constitutes the three major pillars of information technology. It can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. A sensor is an extension of the human five senses and an important link for realizing testing and automatic control.

[0003] When a sensor is in use, it is necessary to conduct regular aging tests on the sensor. Sensor aging tests are to evaluate the performance stability and reliability of the sensor after long-term use and ensure that it can work continuously and stably in actual applications. This kind of test is crucial for ensuring the long-term performance of the sensor under various environmental conditions. In order to facilitate the aging test of the sensor, a test rack is used to conduct batch tests on it.

[0004] Due to different batch numbers of sensors, their sizes are also different. When conducting batch tests on sensors, it is not conducive to adjusting the test spacing according to their model sizes, and it is not convenient to connect the test lines on the test rack to the sensors at corresponding positions for testing. Moreover, it is not convenient to store the test lines, and they are stacked messily together, which is not conducive to the disassembly, assembly, and portability of the test rack. Therefore, we propose a self-made sensor aging test rack to solve the above-mentioned problems. Content of the Utility Model

Specific implementation manners

[0025] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 5 , the present utility model provides the following technical solutions: A self-made sensor aging test rack includes a support bottom plate 1. Support rods 2 are installed at both the left and right ends of the support bottom plate 1. An adjusting screw rod 3 is rotatably connected inside the support rod 2 at the right position. A test board 5 is threadedly connected to the outside of the adjusting screw rod 3. A limit slide bar 4 is installed inside the support rod 2 at the left position. The limit slide bar 4 penetrates through the left end of the test board 5; A fixed seat 16 is installed on the upper side of the test board 5. A test wire 6 is connected to the upper side of the fixed seat 16. A moving block 15 is slidably connected inside the fixed seat 16. An adjustable limit component for positioning it is arranged inside the moving block 15. A positioning card slot 14 is opened on the inner wall of the fixed seat 16;

[0027] Further, the limiting component includes a moving plate 11 slidably connected inside the moving block 15. Compression springs 12 are connected between the moving plates 11. A positioning latch 13 is installed at the end of the moving plate 11, which can limit the position of the moving block 15 to prevent it from moving by itself and stabilize the position of the test line 6. The test plate 5 is slidably connected to the limiting slide bar 4. The limiting slide bar 4 and the adjusting lead screw 3 are arranged in parallel. When the adjusting lead screw 3 rotates to drive the test plate 5 to move, the movement of the test plate 5 can be limited by the limiting slide bar 4 to ensure the vertical movement of the test plate 5. The positions of the limiting through holes 8 correspond to the positions of the test lines 6 one by one. The inner side of the limiting through holes 8 is smooth, which can enable the test lines 6 to pass through the corresponding limiting through holes 8 one by one and prevent the limiting through holes 8 from damaging the test lines 6. The moving plate 11 and the positioning latch 13 are perpendicularly distributed. The moving plates 11 form an elastic structure through the compression springs 12, and the movement of the positioning latch 13 can be driven by controlling the movement of the moving plate 11. The positioning latch 13 is engaged with the positioning slot 14. The positioning slots 14 are equally spaced on the inner wall of the fixed seat 16, which can use the positioning latch 13 and the positioning slot 14 to limit the position of the moving block 15 to prevent it from moving by itself and stabilize the position of the test line 6.

[0028] Fix the support base plate 1 in the working area. The sensors can be sequentially placed at the symmetrical positions corresponding to the test line 6. The test line 6 is connected to the sensors for aging test. Rotate the adjusting lead screw 3 to make the test plate 5 threadedly connected to the outside of the adjusting lead screw 3 move upward. At this time, the other end of the test plate 5 slides on the limiting slide bar 4 to ensure the vertical movement of the test plate 5. By rotating the adjusting lead screw 3 in the reverse direction, the test plate 5 can be controlled to move downward, so that the height position of the test plate 5 can be flexibly adjusted, facilitating comfortable test operations for staff of different heights. Since the model sizes of the sensors are different, the positions of the test lines 6 can be sorted according to the arrangement positions of their sizes. Press the moving plates 11 with two fingers to make the symmetrically distributed moving plates 11 move closer to each other. At the same time, the moving plates 11 press and store energy in the compression springs 12. The moving plates 11 drive the positioning latches 13 installed at their ends to move, and the positioning latches 13 are moved out of the positioning slots 14 to release the fixing of the position of the moving block 15, and then the moving block 15 can be driven to slide in the fixed seat 16, thereby controlling the movement of the support plate 7. The test line 6 passes through the limiting through holes 8 opened at the upper end of the support plate 7, so that the position of the test line 6 can be sorted, making the test head position of the test line 6 aligned with the sensors, ensuring the orderly distribution of the test line 6, preventing it from being randomly piled up and affecting its test efficiency, and facilitating the staff to connect the test line 6 to the sensors in an orderly manner for test operations.

[0029] Furthermore, a support plate 7 is installed at one end of the moving block 15 extending out of the fixed seat 16. Limiting through holes 8 are opened at the upper end of the support plate 7. A protective component for storing the test line 6 is arranged on the support plate 7.

[0030] Specifically, the protection component includes a winding roller 9 installed outside the support plate 7. A limit cover 10 is sleeved outside the winding roller 9, which can wind the test line 6 onto the winding roller 9 for storage and protection.

[0031] Wind the test line 6 passing through the limit through-hole 8 around the winding roller 9. After all winding is completed, the limit cover 10 can be snapped onto the outside of the winding roller 9 to store and limit the test line 6, protect the test line 6, and facilitate the disassembly and carrying of the test stand, avoiding the messy distribution of the test line 6. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
