Quartz tube has the characteristics of high temperature resistance, high transparency, radiation resistance, acid and alkali resistance, etc. It is widely used in optical fiber communication, semiconductors, solar energy, chemical industry, biology, medicine and aviation.

[0003] Ultrasonic thickness measurement is used to measure thickness. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe, and the thickness of the material to be measured is determined by accurately measuring the time it takes for the ultrasonic wave to propagate in the material.

[0004] Traditional quartz tube wall thickness measurement is divided into manual measurement and automatic measurement. Automatic measurement of quartz tube thickness requires the use of precision measuring instruments, such as grating sensors, laser scanners, and high-precision microscopes. The principle of automatic measurement is to scan the surface of the quartz tube wall through the instrument to obtain accurate data on the wall thickness, but the above equipment is not convenient to carry and use, and it is also more troublesome to measure. The ultrasonic thickness measurement equipment is small and easy to carry, but during the detection, due to the different placement and fit of the measuring contact and the outer wall of the pipe, errors are prone to occur.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figure 1-Figure 8 The utility model provides a technical solution: a quartz tube wall thickness measuring device, comprising a measuring device 1, the measuring device 1 comprising a measuring device body 11, 12 connecting wires and a measuring contact 13, one end of the measuring device body 11 is fixedly connected to the connecting wire 12, the other end of the connecting wire 12 is fixedly connected to the measuring contact 13, and a balancing mechanism 2 is installed on the measuring device 1;

[0032] The balancing mechanism 2 includes a handle assembly 21, a fitting assembly 22, an adjustment assembly 23 and a clamp 24. A plurality of fitting assemblies 22 are installed on the handle assembly 21. Two adjacent fitting assemblies 22 are rotatably connected. An adjustment assembly 23 is installed on the top of a middle fitting assembly 22. A clamp 24 is installed on the front end surface of a middle fitting assembly 22. The measuring contact 13 is arranged on the inner side of the clamp 24. When in use, the measuring device body 11 is held in one hand and the handle assembly 21 is held in the other hand. Through the rotational cooperation of the plurality of fitting assemblies 22, the fitting assembly 22 can be recessed upward. When the measuring contact 13 fits the outer wall of the pipeline, a certain number of fitting assemblies 22 fit the pipeline, thereby increasing friction. The fitting assemblies 22 fit the pipeline, so that the measuring contact 13 fits the outer wall of the pipeline better. Then, the measuring device body 11 is operated to perform the measuring contact 13 connected through the connecting line 12, and the measuring data is fed back to the display screen of the measuring device body 11 through the connecting line 12.

[0033] The handle assembly 21 includes a grip 211, a bracket 212, a sleeve 213 and a limit rod 214. The left and right sides of the bottom end of the grip 211 are fixedly connected to the bracket 212, the other end of the bracket 212 is fixedly connected to the sleeve 213, the inner side of the sleeve 213 is slidably connected to the limit rod 214, the limit rod 214 runs through the surface of the sleeve 213, the limit rod 214 is arranged in a "T" shape, the two limit rods 214 are arranged symmetrically on the left and right, the limit rod 214 is arranged in a square shape, and the limit rod 214 is elastic. Each group of fitting components 22 includes an adjusting block 221, a connecting block 222 and a rotating block 223. The left end of the adjusting block 221 is fixedly connected to the connecting block 222, the right end of the adjusting block 221 is fixedly connected to the rotating block 223, and the left side of the adjusting block 2 The front end face of the rotating block 223 on 21 is rotatably connected with the connecting block 222 on the right adjusting block 221 through a rotating shaft, and the ends of the two limit rods 214 close to each other are fixedly connected with the corresponding adjusting blocks 221 respectively. A rotating groove is provided at the left end of the adjusting block 221, and the connecting block 222 is arranged on the inner side wall of the rotating groove. The maximum angle of rotation between two adjacent adjusting blocks 221 is 20°. The front end face of the adjusting block 221 in the middle is fixedly connected with the clamp 24, and the inner side wall of the clamp 24 is detachably connected with the measuring contact 13. When measurement is required, the measuring contact 13 is placed in the clamp 24, and the measuring contact 13 is fixed to the inner side of the clamp 24 by rotating the bolts on the clamp 24. The measuring device body 11 is held in one hand, and the four fingers of the other hand are used to hold the measuring device 11. They are placed in the four grooves of the handle 211 respectively, and the thumb is placed on the push block 232. When measuring the pipeline, the following operations are performed according to different measuring positions. When measuring outside the pipeline, if the outer diameter of the pipeline is smaller than the distance between the two adjacent farthest adjustment blocks 221, the sliding sleeve 213 is placed beside the pipeline, and the adjustment block 221 is placed on the outside of the pipeline to fit the pipeline. The sliding sleeve 213 contacts the pipeline, and the handle 211 is pressed to make the adjustment block 221 fit the outer wall of the pipeline as much as possible. The connecting block 222 and the rotating block 223 can rotate with each other so that the two adjacent adjustment blocks 221 can rotate with each other. The multiple groups of fitting components 22 are concave upwards, which will reduce the total horizontal length of the combination of the fitting components 22. , the adjusting block 221 pulls the limit rod 214 to slide in the sliding sleeve 213, that is, the depression is aligned with the outer side of the pipeline as much as possible, and then the measuring contact 13 connected to the measuring device body 11 through the connecting line 12 is operated to perform the measurement operation. If the outer diameter of the pipeline is greater than the distance between the two adjacent and farthest adjusting blocks 221, when the clamp 24 fixes the measuring contact 13, the measuring contact 13 leaks downward for a large part, and then the clamp 24 fixes the measuring contact 13. The outer side of the pipeline is a curved surface, the sliding sleeve 213 fits with the outer side of the pipeline, and the adjusting block 221 rubs against the outer wall of the pipeline to prevent the measuring contact 13 from moving at will, and ensure that the measuring contact 13 fits as flatly as possible on the outer side of the pipeline, and the measuring contact 13 extends out of the clamp 24 for a large part.That is, the distance between the bottom end face of the measuring contact 13 and the bottom end face of the adjusting block 221 is increased, so that the measuring contact 13 can better fit with the outside of the pipe, and then the edge adjusting block 221 can fit with the outside of the pipe as much as possible, and the width of the adjusting block 221 can also reduce the inclination of the measuring contact 13, so that the measuring contact 13 fits as flatly as possible on the outside of the pipe, which is convenient for measuring operations, reduces the occurrence of inclination of the measuring contact 13, and improves the fitting stability of the measuring contact 13 and the measuring point of the outer wall of the pipe. The friction and fit between the adjusting block 221 and the pipe make the measuring contact 13 fit precisely with the outer wall of the pipe. For a pipe with a small outer diameter, that is, the outer diameter of the pipe is less than the distance between the two adjacent and farthest adjusting blocks 221, the fitting of the adjusting block 221 with the outside of the pipe increases the fitting area, increases the friction, and prevents the measuring contact 13 from moving randomly on the outside of the pipe.

[0034] The adjusting assembly 23 includes a slide bar 231, a pressing block 232, a ball socket 233, a worm 234 and a connecting rod 235. The adjusting block 221 in the middle is fixedly connected to the connecting rod 235. The top of the connecting rod 235 is fixedly connected to the worm 234. The outer side of the worm 234 is rotatably connected to the ball socket 233. The top of the ball socket 233 is fixedly connected to the slide bar 231. The top of the slide bar 231 is fixedly connected to the pressing block 232. The slide bar 231 passes through the surface of the handle 211. The rear end surface of the handle 211 is provided with four grooves. The outer side of the slide bar 231 is slidably connected to the handle 211. The ball socket 233 is set in a three-fifths hollow spherical shape. The outer side of the worm 234 fits with the inner wall of the ball socket 233. When the inner diameter of the pipeline is large, detection is performed on the inner side of the pipeline to press the handle 211. The sliding sleeve 213 is pressed against the inner wall of the pipe through the bracket 212, and then the thumb presses the button 232 to drive the sliding rod 231 to move downward, and the sliding rod 231 drives the ball socket 233 downward, and the ball socket 233 drives the worm 234 downward, and the worm 234 drives the middle adjusting block 221 downward through the connecting rod 235, so that the middle adjusting block 221 drives the measuring contact 13 on the clamp 24 downward, and the multiple groups of fitting components 22 are in a downward protruding shape, and then the thumb keeps pressing the button 232, and then the handle 211 is moved left and right, so that the middle handle 211 is as parallel to the measuring point as possible, the connecting rod 235 and the sliding rod 231 are in a straight line, and the bottom end of the measuring contact 13 is flatly fitted with the inner diameter of the pipe, so that the measuring contact 13 can be measured from the inside of the pipe.

[0035] Working principle: When the device is in use and needs to be measured, the measuring contact 13 is placed in the clamp 24, and the measuring contact 13 is fixed to the inner side of the clamp 24 by rotating the bolt on the clamp 24. The measuring device body 11 is held in one hand, and the four fingers of the other hand are placed in the four grooves of the grip 211, and the thumb is placed on the pressing block 232. When measuring the pipeline, the following operations are performed according to different measuring positions. When measuring outside the pipeline, if the outer diameter of the pipeline is less than the distance between the two adjacent and farthest adjustment blocks 221, the sliding sleeve 213 is placed beside the pipeline, and the adjustment block 221 is placed outside the pipeline to fit the pipeline, and the sliding sleeve 213 is placed on the side of the pipeline. The adjusting block 221 contacts the pipe and presses the grip 211, so that the adjusting block 221 is fitted with the outer wall of the pipe as much as possible. The connecting block 222 and the rotating block 223 can rotate with each other so that the two adjacent adjusting blocks 221 can rotate with each other. The multiple groups of fitting components 22 are concave upwards, which will reduce the total horizontal length of the fitting components 22. The adjusting block 221 pulls the limit rod 214 to slide in the sliding sleeve 213, that is, the concave is aligned with the outer side of the pipe as much as possible. Then, the measuring contact 13 connected by the connecting line 12 of the measuring device body 11 is operated to perform the measurement operation. If the outer diameter of the pipe is greater than the distance between the two adjacent and farthest adjusting blocks 221, the clamp When fixing the measuring contact 13 with the clamp 24, the measuring contact 13 is exposed downward for a large part, and then the clamp 24 is used to fix the measuring contact 13. The outer side of the pipeline is a curved surface, the sliding sleeve 213 fits the outer side of the pipeline, and the adjusting block 221 rubs against the outer wall of the pipeline to prevent the measuring contact 13 from moving at will and ensure that the measuring contact 13 fits the outer side of the pipeline as flatly as possible. The measuring contact 13 extends out of the clamp 24 for a large part, that is, the distance between the bottom end face of the measuring contact 13 and the bottom end face of the adjusting block 221 is increased, so that the measuring contact 13 can better fit the outer side of the pipeline, and then the edge of the adjusting block 221 can fit the outer side of the pipeline as much as possible, and the adjusting block 221 can fit the outer side of the pipeline as much as possible. The width of the section block 221 can also reduce the inclination of the measuring contact 13, so that the measuring contact 13 fits as flatly as possible on the outside of the pipe, which is convenient for measuring operations, reduces the occurrence of inclination of the measuring contact 13, and improves the fitting stability of the measuring contact 13 and the measuring point of the outer wall of the pipe. The friction and fit between the adjustment block 221 and the pipe can make the measuring contact 13 fit precisely with the outer wall of the pipe. For a pipe with a small outer diameter, that is, the outer diameter of the pipe is smaller than the distance between the two adjacent and farthest adjustment blocks 221, the adjustment block 221 fits with the outer side of the pipe to increase the fitting area, increase friction, and prevent the measuring contact 13 from moving randomly on the outside of the pipe.
