DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-8 A high-precision measuring instrument for dangerous rock cracks includes a dial 1; a pressing piece 2; a measuring needle 3; a measuring piece 4, which is used to synchronously measure the depth and width of rock cracks; the measuring piece 4 includes a width measuring device and a depth measuring device; the pressing piece 2 is connected to the measuring piece 4, and pressing the pressing piece 2 will control the width measuring device to expand and abut against the rock crack to achieve width measurement.

[0020] In this embodiment, the width measurement device includes a central gear 401, which is rotatably connected to the interior of the stylus 3. The upper and lower positions of the central gear 401 are respectively meshed with an upper rack 402 and a lower rack 403. The upper rack 402 and the lower rack 403 are connected to the outward sides of the upper rack 402 and the lower rack 403. The surface of the central gear 401 is meshed with a drive rack 405, which is connected to the pressing member 2. When the drive rack 405 moves downward, it will form a meshing rotation effect with the central gear 401. At this time, the mutual engagement of the gears and teeth will synchronously drive the upper rack 402 and the lower rack 403 to expand relative to each other, and then abut against the inner wall of the rock crack to achieve crack measurement. Therefore, the rotation of the central gear 401 is used to achieve relative movement of the upper and lower racks, ultimately achieving press-type mobile measurement.

[0021] Furthermore, the stylus 3 is connected to the bottom of the dial 1, and the pressing member 2 is located above the dial 1. A limiting slot 404 is provided inside the stylus 3, and the upper rack 402 and the lower rack 403 are slidably connected inside the limiting slot 404. The limiting slot 404 can restrict the upper rack 402 and the lower rack 403 to only lateral sliding, thereby preventing the upper rack 402 and the lower rack 403 from offsetting and causing deviation in the measurement data.

[0022] Furthermore, the depth measuring device includes a clamping strip 406, a slide groove 407 is provided on the measuring needle 3, the clamping strip 406 is slidably connected to the slide groove 407, a half slide bar 408 is connected to the clamping strip 406, the top of the half slide bar 408 is connected to the upper gear rod 409, the surface of the upper gear rod 409 is meshed with a first gear 410, the axis of the first gear 410 is connected to a center sleeve 412, and the center sleeve 412 is connected to a pointer 411. When the stylus 3 penetrates into the crack, the clamping strip 406 will contact the outer surface of the crack. After the stylus 3 penetrates into the crack, the clamping strip 406 will be squeezed to slide in the slide groove 407, thereby driving the semi-slide rod 408 to move upward, and then the upper gear rod 409 moves upward synchronously, thereby driving the meshing rotation of the first gear 410. The rotation of the first gear 410 will synchronously drive the rotation of the pointer 1 411 through the center sleeve 412. Therefore, the operator can now intuitively view the depth of the crack detected at this time according to the rotation of the pointer 1 411.

[0023] In addition, a slide bar is fixedly connected to the interior of the dial 1, and a return spring 413 is sleeved on the surface of the slide bar. The upper gear bar 409 is slidably connected to the slide bar, and the bottom of the return spring 413 abuts against the upper gear bar 409. The return spring 413 can reset the pointer 1 411 and the clamping bar 406 after the measuring instrument is withdrawn from the gap, facilitating the next measurement.

[0024] In addition, the pressing part 2 includes a pressure rod 201, the surface of the pressure rod 201 is sleeved with an extrusion spring 204, the top of the pressure rod 201 is connected to a pressure ball 202, the bottom of the pressure rod 201 is connected to a lower gear rod 414, the bottom of the lower gear rod 414 is connected to a semi-slide rod 2 418, the bottom of the semi-slide rod 2 418 is connected to the driving rack 405, the surface of the lower gear rod 414 is meshed with a second gear 415, the axis of the second gear 415 is connected to a circular sleeve 416, and the circular sleeve 416 is connected to a pointer 2 417. The control pressure ball 202 drives the pressure rod 201 to be pressed down, and then drives the lower gear rod 414 to move downward. At this time, during the downward movement of the lower gear rod 414, the meshing rotation of the gears will drive the meshing rotation of the second gear 415, and the rotation of the second gear 415 will drive the pointer 2 417 on the circular sleeve 416 to rotate. Therefore, the operator can intuitively see the width of the rock crack at this time according to the rotation angle of the pointer 2 417.

[0025] It is worth noting that the dial 1 is connected to two pull-edges 203, and the dial 1 is provided with scale lines 1 and 2. Scale line 1 is the depth scale line, and scale line 2 is the width scale line. The two scale lines can realize the dual display of the depth and the width of the crack, which makes the operator more intuitive during the inspection.

[0026] It is worth noting that it also includes a marking part 5, which includes a sliding piece 502, which is slidably connected to the inside of the dial 1, and a support spring 503 is abutted on one side of the sliding piece 502, and one end of the support spring 503 is abutted on the inner wall of the dial 1, and a center rod 504 is connected to the sliding piece 502, and a ring 505 is connected to one end of the center rod 504, and a paintbrush 506 is provided on the ring 505, and the paintbrush 506 is inserted into the pointer 2 417, and a cam 501 is connected to the surface of the pressure rod 201, and the cam 501 abuts against the sliding piece 502 when it rotates, and the lower gear rod 414 is rotatably connected to the pressure rod 201. The operator rotates the pressure ball 202 with the palm of his hand, and then the pressure rod 201 rotates synchronously, thereby driving the cam 501 to rotate. When the cam 501 rotates, it will form an abutment and sliding with the sliding piece 502, thereby controlling the lateral movement of the sliding piece 502. After that, the sliding piece 502 moves, and the ring 505 is driven to move laterally through the center rod 504. The groove on the ring 505 will drive the snap ring 507 and the paintbrush 506 connected to the snap ring 507 to move, thereby making the paintbrush 506 abut against the surface of the dial 1. At this time, the paintbrush 506 directly points out the mark. When measuring for the second time, the same principle is still used to point out the second mark point. By analogy, the operator can view multiple measurement values ​​according to the marked points, provide comparison parameters for measurement, and do not need to rely on manual memory or manual recording, providing a certain convenience for detection and comparison.

[0027] It is worth mentioning that the ring 505 is provided with an arc groove, on which a snap ring 507 is slidably connected, and the snap ring 507 is connected to the paintbrush 506. The arc groove can indirectly form a snap connection with the snap ring 507, so that the subsequent rotation of the control ball 202 will synchronously and indirectly drive the movement of the paintbrush 506, thereby controlling the paintbrush 506 to abut against the dial 1 to form a mark.

[0028] Working principle: first, when measuring the rock gap, the operator needs to insert the entire probe 3 into the inside of the gap, then the middle finger and index finger are stuck in the position of the two pull handles 203, and then the palm of the hand exerts force to control the pressure ball 202 to drive the pressure rod 201 to press down, and then drive the lower gear rod 414 to move downward, and then synchronously drive the semi-slide rod 418 to move downward, and then the semi-slide rod 418 will drive the driving rack 405 to move downward, and the driving rack 405 moves downward, which will form an effect of meshing rotation with the central gear 401, so At this time, the mutual engagement of the gears and the teeth will synchronously drive the upper rack 402 and the lower rack 403 to expand relative to each other, and then abut against the inner wall of the rock crack to achieve crack measurement. At this time, during the downward movement of the lower rack rod 414, the meshing rotation of the gears will also drive the meshing rotation of the second gear 415, and the rotation of the second gear 415 will drive the pointer 2 417 on the circular sleeve 416 to rotate, so at this time the operator can intuitively see the width of the rock crack at this time according to the rotation angle of the pointer 2 417. The entire measuring instrument is also equipped with a depth measurement device to measure the crack width at different depths. Because different depths may correspond to different widths when measuring cracks, and traditional measuring instruments cannot measure different depths, the depth measurement designed in this technical solution is synchronized. Specifically, when the stylus 3 penetrates deep into the crack, the clamping strip 406 will be against the outer surface of the crack. When the stylus 3 penetrates deep, it will squeeze the clamping strip 406 to slide in the slide groove 407, thereby driving the semi-slide rod 408 to move upward, and then the upper gear rod 409 will move upward synchronously, thereby driving the meshing rotation of the first gear 410. The rotation of the first gear 410 will synchronously drive the rotation of the pointer 411 through the center sleeve 412. Therefore, the operator can intuitively view the depth of the crack detected at this time according to the rotation of the pointer 411. Therefore, the inspector can perform multiple measurements: one is to directly detect the crack width, the second is the crack depth, and the third is the crack width at different depths. In order to facilitate overall recording, the entire measuring instrument is also provided with a marking part 5, which is used to mark the value of each measurement, so that the value of each measurement can be compared without recording.The specific process is that when the crack width measurement value is displayed, the operator rotates the pressure ball 202 with the palm of his hand, and then the pressure rod 201 rotates synchronously, thereby driving the cam 501 to rotate. Under the condition of the rotation of the cam 501, it will form an abutment and sliding with the sliding piece 502, thereby controlling the lateral movement of the sliding piece 502. After that, the sliding piece 502 moves, and the ring 505 is driven to move horizontally through the center rod 504. The groove on the ring 505 will drive the snap ring 507 and the paintbrush 506 connected to the snap ring 507 to move, so that the paintbrush 506 is abutted against the surface of the dial 1, so at this time the paintbrush 506 is Pen 506 directly points out the mark. When the second measurement is taken, the same principle is still used to point out the second mark point. Similarly, the operator can view multiple measurement values ​​based on the marked points. At the same time, it can also be used in some special environments, that is, when the entire measuring instrument is inserted into a large gap for measurement, it is inconvenient for the operator to see the dial 1. Therefore, by using the marking method, after detecting the crack and marking it, the operator can view the measurement value based on the marked position. Of course, the entire pen 506 is plugged into pointer 2 417. When the operator does not need to mark or replace the pen 506, the pen 506 can be directly pulled out. The marking surface of the dial 1 is a glass surface, and the pen 506 can be manually wiped after marking, avoiding the clutter on the dial 1 when marking multiple points. Therefore, after measuring each set of values, the tester can wipe the marked points as needed. Using the setting of the marking member 5, the numerical comparison difference of each detection point can be directly viewed, without the need for manual numerical recording, which improves the overall convenience of the test.
