[0002] After the production of pharmaceutical glass tubes is completed, there will be a certain deviation in straightness due to errors generated during the production process. Therefore, it is necessary to use a straightness measuring device to test the straightness of the produced glass tubes to ensure that they can be used only after they meet the qualified standards. According to the prior art, such as the pharmaceutical glass tube straightness tester described in Chinese patent document CN214407423U, the disclosed technical solution makes the probe of the measuring table contact the outer surface of the glass tube, so that the first slider slides up and down, and the vertical changes of the measuring table are recorded at this time. If needed, the rotating seat can be rotated again and measured and recorded again. The device has a fast measurement speed and high accuracy, which is beneficial for enterprises to improve production efficiency.

[0003] According to the disclosed technical solution, the measuring device in the prior art can only measure one side of the glass tube. When it is necessary to measure the contours of the glass tube in multiple directions, it is necessary to repeat the measuring steps many times, which makes the use cumbersome and can only measure the straightness problem, but cannot measure deformation problems such as bending and bulging at the same time. The measurement is not comprehensive, and each measurement needs to be manually checked to determine whether it is qualified, which increases the workload of the operator. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a glass tube straightness measuring device to solve the problems raised in the above-mentioned background technology. The utility model can simultaneously provide measurement for any contour of the side of the glass tube, thereby improving the measurement efficiency, reducing the workload of the operator, and being able to quickly obtain the qualified result.

[0006] Furthermore, the detection mechanism includes a clamping ring and a transmission rod, a docking stud is installed at the end of the transmission rod, and a conductive ring is fixedly installed at the end of the docking stud, and a through hole is opened in the center of the conductive ring.

[0007] Furthermore, the side of the conductive ring is connected with a power supply line, and the power supply line is connected to an external power device. The transmission rod is fixedly installed on both sides of the conductive ring in a symmetrical manner, and the transmission rod is made of insulating plastic material as a whole.

[0008] Furthermore, the inner ring diameter of the clamping ring is the same as the inner wall diameter of the mounting sleeve, and the central axes of the clamping ring and the mounting sleeve coincide with each other. A threaded hole is provided at the end of the transmission rod, and the docking stud is embedded in the threaded hole.

[0009] Furthermore, the lifting mechanism includes an electric lifting rod and a driving collar, the bottom of the driving collar is bonded with a support plate, the bottom of the electric lifting rod is fixedly mounted on the measuring platform, and the top of the electric lifting rod is fixedly connected to the bottom of the support plate.

[0010] Furthermore, a movable groove is provided on the side of the driving collar, the transmission rod passes through the inside of the movable groove, and the height of the movable groove is the same as the diameter of the transmission rod.

[0013] Beneficial effects of the utility model:

[0014] Since the glass tube straightness measuring device can directly fit with any orientation of the surface of the glass tube to be measured through the clamping ring on the inner side of the detection mechanism, it can directly detect the problem of the glass tube tilting in any direction in the subsequent measurement process, without the need for multiple measurements, thereby simplifying the operation steps.

[0015] The glass tube straightness measuring device can directly set the detection mechanism on the surface of the glass tube to be measured, and cooperate with the subsequent lifting mechanism to control the detection mechanism to move upward. During the entire measurement process, as long as the glass tube is bent at any position, it will be detected. Therefore, it is possible to measure various deformation problems such as tilt, bulge, and bend, thereby improving the comprehensiveness of the measurement.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides the following technical solutions: a glass tube straightness measuring device, including a measuring device body, the measuring device body including a measuring platform 1, a warning module 2, a detection mechanism 3 and a lifting mechanism 4, two warning modules 2 are installed on the surface of the measuring platform 1, and a mounting sleeve 17 is provided in the middle position of the surface of the measuring platform 1, the two warning modules 2 are fixed at the two ends of the mounting sleeve 17 in a symmetrical form, the side of the mounting sleeve 17 is provided with a lifting mechanism 4, the top of the lifting mechanism 4 is installed with a detection mechanism 3, the two ends of the detection mechanism 3 are provided with conductive rings 9, and each conductive ring 9 is installed on the top of the warning module 2. The glass tube straightness measuring device is used to detect the straightness and deformation problems such as bulges and bends of medicinal glass tubes after production. When in use, the bottom of the glass tube to be tested is directly embedded in the interior of the mounting sleeve 17, and it passes through the center of the detection mechanism 3. Then, the detection mechanism 3 can be controlled to move upward with the help of the lifting mechanism 4. During the upward movement, the alarm modules at both ends are used to detect whether the straightness deviation of the glass tube to be tested exceeds the allowable range. At the same time, the glass tube to be tested is also detected whether it has serious bending, bulges and other problems.

[0024] In this embodiment, the detection mechanism 3 includes a clamping ring 6 and a transmission rod 5, a docking stud 8 is installed at the end of the transmission rod 5, and a conductive ring 9 is fixedly installed at the end of the docking stud 8, a through hole 11 is opened in the center of the conductive ring 9, a power supply line 10 is connected to the side of the conductive ring 9, and the power supply line 10 is connected to the external power equipment, the transmission rod 5 is fixedly installed on both sides of the conductive ring 9 in a symmetrical form, and the transmission rod 5 is made of insulating plastic material as a whole, the inner ring diameter of the clamping ring 6 is the same as the inner wall diameter of the installation sleeve 17, and the central axis of the clamping ring 6 and the installation sleeve 17 coincide, and a threaded hole 7 is opened at the end of the transmission rod 5, and the docking stud 8 is embedded in the threaded hole 7. Since the clamping ring 6 on the inner side of the detection mechanism 3 is directly fitted with any orientation of the surface of the glass tube to be tested, it is possible to directly detect the problem of the glass tube tilting in any direction in the subsequent measurement process, without the need for multiple measurements, thereby simplifying the operation steps.

[0025] Specifically, during the detection process, when the lifting mechanism 4 rises, it will drive the entire detection mechanism 3 to move upward. Since the detection mechanism 3 is mounted on the surface of the glass tube to be tested through the clamping ring 6 in the middle, when the straightness of the glass tube to be tested has a large deviation, it will cause the transmission rods 5 at both ends to translate, and then transmit it to the conductive rings 9 at both ends until the inner wall of the conductive ring 9 contacts the conductive column 21 to complete the generation of electrical signals and trigger an alarm. At this time, the warning light 22 can be lit to determine that the straightness measurement of the glass tube to be tested has failed.

[0026] In this embodiment, the lifting mechanism 4 includes an electric lifting rod 15 and a driving collar 13, the bottom of the driving collar 13 is bonded with a support plate 12, the bottom of the electric lifting rod 15 is fixedly mounted on the measuring platform 1, the top of the electric lifting rod 15 is fixedly connected to the bottom of the support plate 12, and the side of the driving collar 13 is provided with a movable groove 14, the transmission rod 5 passes through the inside of the movable groove 14, and the height of the movable groove 14 is the same as the diameter of the transmission rod 5. By directly sleeve-mounting the detection mechanism 3 on the surface of the glass tube to be measured, the subsequent lifting mechanism 4 can be coordinated to control the detection mechanism 3 to move upward, and in the entire measurement process, as long as the glass tube is bent at any position, it will be detected, so it can realize the measurement of various deformation problems such as tilt, bulge, bending, etc., and improve the comprehensiveness of the measurement.

[0027] Specifically, by starting the electric lifting rod 15, the top support plate 12 can be lifted upward, thereby driving the driving ring 13 to move upward. Since the transmission rod 5 passes through the inside of the movable groove 14, the transmission rod 5 and the middle clamping ring 6 can be controlled to move upward, thereby realizing the above-mentioned upward detection process along the surface of the glass tube to be tested.

[0028] In this embodiment, a fixed base 16 is arranged in the middle of the surface of the measuring platform 1, the mounting sleeve 17 is arranged on the top of the fixed base 16, and a non-slip rubber ring 18 is attached to the inner wall of the mounting sleeve 17. The warning module 2 includes a mounting plate 19 and a warning light 22. The warning light 22 is fixed to one end of the surface of the mounting plate 19, and a slot 20 is provided at the other end of the surface of the mounting plate 19. A conductive column 21 is inserted into the slot 20. The bottom of the conductive column 21 is partially electrically connected to the warning light 22 through a conductor structure, and the conductive ring 9 is sleeved on the surface of the conductive column 21 through the middle through hole 11. The entire measurement process only requires placing the glass tube to be measured into the interior of the mounting sleeve 17 and passing it through the detection mechanism 3, and then the lifting mechanism 4 can cooperate with the warning module 2 to automatically complete the detection process, and an alarm can be issued when any type of deformation or excessive straightness difference occurs. The straightness deviation range of the glass tube is adjustable, which is simpler and more convenient to use, and the detection process has high stability.

[0029] Specifically, when the surface straightness deviation of the glass tube to be tested is too large or there are serious protrusions or bends, the conductive rings 9 at both ends will shift until the inner side of the conductive ring 9 contacts the surface of the conductive column 21 to trigger an alarm, thereby realizing an automatic detection process. The conductive ring 9 can be replaced by matching the docking stud 8 and the threaded hole 7, so different sizes of the through hole 11 can be replaced to set the range of allowable deviation of the straightness of the glass tube to be tested.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
