Description

Technical Field

[0001] This utility model relates to the field of data acquisition board technology, specifically a data acquisition board that is easy to assemble and disassemble. Background Technology

[0002] In early applications of electronic devices and testing systems, data acquisition boards were typically installed using a conventional fixed method. Most of these installations involved directly fixing the boards to slots or backplanes inside the chassis with a large number of screws. This method made maintenance, replacement, or upgrades of the boards extremely cumbersome.

[0003] Operators often need to use specialized screwdrivers to unscrew multiple screws one by one, and they must be careful to avoid losing screws during the process. The entire disassembly and assembly process is time-consuming. This traditional installation and disassembly method seriously affects work efficiency, especially in industrial testing and scientific research environments where continuous operation of equipment is required and rapid replacement of circuit boards is necessary.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-8 This utility model provides a data acquisition board that is easy to assemble and disassemble, including a chassis 1. A base plate 9 is fixedly installed at the bottom of the chassis 1. Three limiting grooves 23 are opened on the top of the base plate 9. Moving blocks 10 are slidably connected to the inner cavities of the three limiting grooves 23. A locking block 3 is fixedly installed on the top of each of the three moving blocks 10. An adjustment structure is driven in the middle of the three locking blocks 3. A first moving groove 14 is opened in the middle of the moving block 10. A pressing structure is rotatably connected to the inner cavity of the first moving groove 14. The adjustment structure includes an adjusting wheel 4. A reciprocating screw 5 is fixedly installed at one end of the adjusting wheel 4. The outer ring of the reciprocating screw 5 rotates... The first connecting block 6 is dynamically connected. The two ends of the first connecting block 6 are fixedly provided with second connecting members 21. The inner cavity of the second connecting member 21 is rotatably connected with the first connecting member 20. One end of the first connecting member 20 is fixedly provided with the second connecting block 7. The end of the first connecting member 20 away from the second connecting member 21 is rotatably connected with the third connecting member 22. One end of the third connecting member 22 is fixedly provided with the third connecting block 8. The front of the chassis 1 is provided with a placement slot 26. Both sides of the placement slot 26 are provided with snap-fit ​​slots 25. A snap-fit ​​plate 24 is slidably connected between the two snap-fit ​​slots 25. The three limiting slots 23 are arranged in a triangular shape.

[0023] In this embodiment, the following steps are taken: By rotating the adjusting wheel 4, the adjusting wheel 4 drives the reciprocating screw 5 to rotate. The reciprocating screw 5 rotates and drives the first connecting block 6, allowing the first connecting block 6 to move back and forth. The back and forth movement of the first connecting block 6 drives the first connecting member 20 through the second connecting member 21. The first connecting member 20 drives the second connecting block 7 to push the third connecting block 8, allowing the third connecting block 8 to push the moving block 10. This causes the moving block 10 to move within the limiting groove 23. The movement of the moving block 10 drives the locking block 3. After adjusting to the appropriate position, the locking plate 24 is removed. Then, the plate is placed on the telescopic plate 2 through the placement groove 26, positioned between the locking block 3 and the telescopic plate 2. Then, it is pressed, causing the pressing structure to press and lock the plate.

[0024] Please see Figure 1-8 Furthermore, the pressing structure includes a pressing block 11, the inner cavity of the pressing block 11 is provided with a second moving groove 15, the middle of the second moving groove 15 is provided with an adjusting groove 16, the two sides of the inner cavity of the adjusting groove 16 are provided with rotating grooves 19, the inner cavity of the rotating groove 19 is slidably connected with a moving wheel 18, the middle of the moving wheel 18 is fixedly provided with a connecting rod 17, one end of the connecting rod 17 is fixedly provided with an adjusting rod 13, the bottom of the pressing block 11 is fixedly provided with a spring 12, and the top of the pressing block 11 is fixedly provided with a telescopic plate 2.

[0025] In this embodiment of the application, when the telescopic plate 2 is pressed down, the pressing block 11 is pushed down, so that the adjusting rod 13 drives the moving wheel 18 through the connecting rod 17 to slide and engage in the rotating groove 19 opened on both sides of the inner cavity of the adjusting groove 16. When pushing, the tension is released by the spring 12 to push the pressing block 11 to perform the engagement and limit.

[0026] In practical use, rotating the adjusting wheel 4 causes the reciprocating screw 5 to rotate, which in turn drives the first connecting block 6 to move back and forth. This movement of the first connecting block 6, via the second connecting member 21, drives the first connecting member 20. The first connecting member 20 then drives the second connecting block 7 to push the third connecting block 8, which in turn pushes the moving block 10. This causes the moving block 10 to move within the limiting groove 23. The movement of the moving block 10 then moves the locking block 3. After adjusting to the appropriate position, the locking plate 24 is removed, and the plate is then placed onto the telescopic plate 2 through the placement groove 26, positioned between the locking block 3 and the telescopic plate 2. Finally, the external mechanism... Pressing the plate causes the telescopic plate 2 to push the pressing block 11 downward, compressing the spring 12. This causes the adjusting rod 13 to drive the moving wheel 18 through the connecting rod 17, limiting its movement within the rotating grooves 19 on both sides of the inner cavity of the adjusting groove 16. The moving wheel 18 is positioned in the recess at the top of the adjusting groove 16, thus limiting its movement. Then, the tension is released by the spring 12 to push the pressing block 11 upward, causing the pressing block 11 to press the telescopic plate 2 upward. This allows the pressing block 11 to press the plate against the locking block 3 for locking and fixing. After fixing, the locking plate 24 is placed into the placement groove 26 through the locking groove 25. When replacement is needed, the locking plate 24 is removed, and the telescopic plate 2 is pressed again so that the moving wheel 18 is at the bottom of the adjusting groove 16.

[0027] 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
