Description

Technical Field

[0001] This utility model belongs to the field of electronic measuring instrument technology, and in particular relates to a fixed structure for a digital oscilloscope signal board. Background Technology

[0002] A digital oscilloscope is a high-performance oscilloscope manufactured using a series of technologies such as data acquisition and software programming. It generally supports multi-level menus, providing users with a variety of options and analysis functions. Some also offer storage functions, enabling the saving and processing of waveforms. A digital oscilloscope samples analog signals through a data acquisition system, converts them into digital signals, and then goes through storage, processing, and display stages to finally present the waveform of the signal on the screen.

[0003] Some devices use bolts to fix the signal board to the housing. When directly fixing the signal board with bolts, the bolt holes of the signal board and the housing need to be repeatedly adjusted to ensure alignment, which is time-consuming. Therefore, a digital oscilloscope signal board fixing structure is needed. The connector drives the locking block to move down, so that the locking block, fixing block and slider are squeezed and locked together for pre-fixation. This effectively avoids the need to repeatedly adjust the bolt holes when bolting the housing and the signal board, thereby improving the ease of installation. Utility Model Content

[0004] The purpose of this invention is to provide a fixing structure for a digital oscilloscope signal board, which uses a connector to drive a locking block to move downward, so that the locking block, fixing block, and slider are squeezed and locked together for pre-fixation. This effectively avoids the need for repeated adjustment of bolt holes when bolting between the housing and the signal board, thereby improving the ease of installation and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A digital oscilloscope signal board fixing structure includes a housing, two connecting rods fixedly connected to the inner wall of the housing, a slider slidably connected to the surface of the connecting rod, a fixing block fixedly connected to the top of the connecting rod, a limit ring integrally formed on the surface of the connecting rod, a signal board disposed in the inner cavity of the housing, a bolt rod jointly installed between the housing and the signal board, joints fixedly connected to the left and right sides of the signal board, a sliding groove is provided on the inner wall of each of the two joints, two sliding rods slidably connected to the surface of the sliding groove, a locking block fixedly connected to the end of the sliding rod, and a spring sleeved on the surface of the sliding rod.

[0006] Preferably, both the slider and the fixing block are slidably connected to the inner cavity of the connector, and the dimensions of the slider and the fixing block are adapted to the inner cavity of the connector.

[0007] Preferably, the two ends of the spring are in contact with the surfaces of the locking block and the sliding groove, respectively.

[0008] Preferably, the surface of the card block has an inclined surface.

[0009] Preferably, each end of the two slide bars is fixedly connected to a limiting block, and the limiting block is an annular limiting block.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a signal board to drive the connector to move downward, so that the connector drives the locking block and slider to contact the fixing block, thereby squeezing and locking the slider and fixing block with the connector. This effectively avoids the need to repeatedly adjust the bolt holes when bolting the housing and the signal board, thus improving the ease of installation.

[0012] 2. By setting the inclined surface, the surface of the card block is treated with an inclined surface, which reduces the frictional force when the spring squeezes the fixed block and reduces frictional loss.

[0013] 3. This utility model limits the movement of the slide rod by setting a limiting block, thus preventing the slide rod from accidentally sliding off the surface of the slide groove when it moves. Attached Figure Description

[0021] In the following description, embodiments of the digital oscilloscope signal board fixing structure of this utility model will be described with reference to the accompanying drawings.

[0022] Example 1:

[0023] Figure 1-4 This invention illustrates a digital oscilloscope signal board fixing structure according to an embodiment of the present invention, comprising: a housing 1; two connecting rods 2 fixedly connected to the inner wall of the housing 1; sliders 3 slidably connected to the surface of the connecting rods 2; a fixing block 4 fixedly connected to the top of the connecting rods 2; a limit ring 5 integrally formed on the surface of the connecting rods 2; a signal board 6 disposed in the inner cavity of the housing 1; a bolt rod 7 jointly installed between the housing 1 and the signal board 6; connectors 8 fixedly connected to the left and right sides of the signal board 6; and sliders 3 and fixing blocks 4 slidably connected to the inner cavity of connectors 8. Next, the dimensions of the slider 3 and the fixed block 4 are adapted to the inner cavity of the connector 8. The inner walls of the two connectors 8 are provided with sliding grooves 9. Two sliding rods 10 are slidably connected to the surface of the sliding grooves 9. The ends of the sliding rods 10 are fixedly connected with locking blocks 11. Springs 12 are sleeved on the surface of the sliding rods 10. Limiting blocks 14 are fixedly connected to the ends of the two sliding rods 10. The limiting blocks 14 are annular limiting blocks. By setting the limiting blocks 14, the movement of the sliding rods 10 is limited, avoiding the situation where the sliding rods 10 accidentally slide out of the surface of the sliding grooves 9 when moving.

[0024] Example 2:

[0025] Figure 1-4 This invention illustrates a digital oscilloscope signal board fixing structure according to an embodiment of the present invention, comprising: a housing 1, two connecting rods 2 fixedly connected to the inner wall of the housing 1, a slider 3 slidably connected to the surface of the connecting rods 2, a fixing block 4 fixedly connected to the top of the connecting rods 2, a limit ring 5 integrally formed on the surface of the connecting rods 2, a signal board 6 disposed in the inner cavity of the housing 1, a bolt rod 7 jointly installed between the housing 1 and the signal board 6, connectors 8 fixedly connected to the left and right sides of the signal board 6, a groove 9 provided on the inner wall of each of the two connectors 8, two sliding rods 10 slidably connected to the surface of the grooves 9, a locking block 11 fixedly connected to the end of the sliding rod 10, a spring 12 sleeved on the surface of the sliding rod 10, the two ends of the spring 12 respectively contacting the surfaces of the locking block 11 and the grooves 9, and a beveled surface 13 provided on the surface of the locking block 11. The beveled surface 13 reduces the frictional force when the spring 12 presses against the fixing block 4, thereby reducing frictional loss.

[0026] Working principle: When using this utility model, the user presses down on the connector 8, causing the connector 8 to move the locking block 11 downward, so that the locking block 11 contacts and presses against the fixing block 4. When the locking block 11 moves to a certain depth, the spring 12 returns the locking block 11 to its original position and engages with the slider 3 and the fixing block 4, thus positioning the housing 1 and the signal board 6. Then, the bolt rod 7 fixes the housing 1 and the signal board 6. When the signal board 6 needs to be maintained or replaced, the user presses down on the connector 8, causing the connector 8 to move the locking block 11 downward, so that the locking block 11 moves the slider 3 to slide on the surface of the connecting rod 2. The movement of the slider 3 is limited by the setting of the limiting ring 5. At this time, under the elastic force of the spring 12, the surface of the locking block 11 and the slider 3 are in contact. Then, the connector 8 is lifted to separate the housing 1 and the signal board 6, effectively avoiding the need for repeated adjustment of the bolt holes when bolting the housing and the signal board, thereby improving the ease of installation.

[0027] In summary, the signal board fixing structure of this digital oscilloscope uses the signal board 6 to drive the connector 8 to move downwards, causing the connector 8 to drive the locking block 11 and the slider 3 to contact the fixing block 4. This allows the slider 3 and the fixing block 4 to be pressed and locked with the connector 8, effectively avoiding the need for repeated adjustment of bolt holes when bolting between the housing and the signal board, thus improving the ease of installation.
