[0023] Example 1

[0024] As Figure 1 - Figure 4 The utility model discloses a digital capacitor protection accuse device, including accuse appearance main part 1 and setting accuse appearance main part 1 on the outer frame 2, still including:

[0025] Limit strip 3, limit strip 3 sliding sets up accuse appearance main part 1 upper and lower both ends, accuse appearance main part 1 is fixed on the control cabinet through limit strip 3;

[0026] Jacking strip 4, jacking strip 4 sliding sets up on the outer frame 2, changes limit strip 3 height through adjusting jacking strip 4 position;

[0027] Adjusting rod 5, adjusting rod 5 rotation sets up on the outer frame 2, changes jacking strip 4 position through adjusting rod 5.

[0028] Clamping strip 31 is set up on limit strip 3, can firmly hook the edge of control cabinet, realizes stable fixation, and the lower surface of limit strip 3 is provided with inclined surface A 32, and the both sides of the lower surface of limit strip 3 are embedded with spring 33, and limit strip 3 is provided with a certain elasticity, so that it can reset in the first time, and limit strip 3 is connected with accuse appearance main part 1 through spring 33.

[0029] Accuse appearance main part 1 upper and lower both ends are provided with containing cavity 6, and limit strip 3 is arranged in containing cavity 6, and avoiding groove 61 is formed in containing cavity 6, and limit strip 3 penetrates accuse appearance main part 1 top wall through avoiding groove 61.

[0030] Inclined surface B 41 is formed on jacking strip 4, and inclined surface B 41 is matched with inclined surface A 32, so as to convert the rotary motion of adjusting rod 5 into the up-down linear motion of limit strip 3, threaded groove 42 is formed on jacking strip 4, and limit groove 43 is formed on the both sides of jacking strip 4.

[0031] The outer frame 2 is provided with a sliding groove 21, which provides a precise track for the sliding of the top driving strip 4, ensuring the stability of the movement. The limiting strip 3 is slidably arranged in the sliding groove 21, and the sliding groove 21 is provided with a protrusion 23 on both sides, which can be embedded in the limiting groove 43, thereby limiting the movement range of the top driving strip 4, ensuring the stability during the adjustment of the device. The outer frame 2 is provided with a through groove 22, which is communicated with the sliding groove 21, and the adjusting rod 5 penetrates the outer frame 2 through the through groove 22.

[0032] The adjusting rod 5 is provided with a limiting ring 52, which effectively prevents the axial movement of the adjusting rod 5 during rotation. The limiting ring 52 is arranged in the sliding groove 21, and the adjusting rod 5 is provided with an adjusting knob 53, which is arranged outside the outer frame 2. The adjusting knob 53 is provided with a mark, and the adjusting rod 5 is provided with a thread 51. The adjusting rod 5 is connected with the threaded groove 42 through the thread 51. Through threaded transmission, only by rotating the adjusting knob 53, the precise displacement of the top driving strip 4 can be realized.

[0033] It should be noted that the working principle of the digital capacitor protection measurement and control device is as follows: when it is necessary to fix the measurement and control instrument body 1 on the control cabinet, first, the measurement and control instrument body 1 is placed in the reserved hole of the control cabinet, and then the adjusting rod 5 is operated. The adjusting rod 5 is rotatably arranged on the outer frame 2 and penetrates the outer frame 2 through the through groove 22. The thread 51 on the adjusting rod 5 is connected with the threaded groove 42 on the top driving strip 4. By rotating the adjusting knob 53 on the adjusting rod 5, the adjusting rod 5 can be rotated, thereby driving the top driving strip 4 to slide in the sliding groove 21. The limiting groove 43 on both sides of the top driving strip 4 cooperates with the protrusion 23 on both sides of the sliding groove 21, ensuring the stable sliding of the top driving strip 4 and limiting the movement distance of the top driving strip 4. Since the inclined surface B41 on the top driving strip 4 matches the inclined surface A32 of the limiting strip 3, as the position of the top driving strip 4 changes, the top driving strip 4 pushes the limiting strip 3 to slide up and down along the containing cavity 6 through the inclined surface B41, thereby changing the height of the limiting strip 3. The clamping strip 31 on the limiting strip 3 stably fixes the measurement and control instrument body 1 on the control cabinet, and is not limited by the size of the reserved hole on the control cabinet. Even if the size of the hole is too large, the height of the limiting strip 3 can be accurately adjusted to stably fix the measurement and control instrument body 1 on the control cabinet.
