[0024] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described below.

[0025] To address the problems existing in the background technology, this application proposes the following technical solution: an inner diameter detection device for the production of quartz tube 2, comprising a base 1, a housing 4 fixedly connected to both sides of the top of the base 1, a scale line 10 also provided on the top of the base 1, a sliding plate 5 slidably connected inside the housing 4, a first spring 6 connected between the sliding plate 5 and the housing 4, a first detection plate 11 fixedly connected to the top of the sliding plate 5, a second detection plate 12 fixedly connected to the outside of the first detection plate 11, pointers 20 fixedly connected to the bottom of the sliding plate 5, the pointers 20 and the second detection plate 12 being on the same horizontal line in the vertical direction, a digital display component also provided on the base 1, a beveled edge provided on one side of the top of the first detection plate 11 and the second detection plate 12, the thickness of the first detection plate 11 being greater than the thickness of the second detection plate 12, and a support frame fixedly connected to both sides of the bottom of the base 1, the support frame being a rectangular hollow structure. The top of the housing 4 is detachably and fixedly connected to a top cover, and one end of the housing 4 is an open structure. The base 1 serves as the basic support for the entire testing device, providing a stable mounting platform for each component and ensuring that the device will not be affected by shaking during the testing process. The housing 4 on both sides of the top provides a closed sliding space for the slide plate 5, preventing external dust and impurities from entering and affecting the operation of the components. The scale line 10 on the top of the base 1, together with the pointer 20, provides an intuitive reading function, allowing the operator to quickly obtain preliminary data on the inner diameter of the quartz tube 2. The slide plate 5, which is slidably connected inside the housing 4, can move flexibly under the elastic force of the first spring 6. The first spring 6 always applies an outward pushing force to the slide plate 5. When the quartz tube 2 is fitted into the testing plate, the slide plate 5 will automatically adjust its position according to the inner diameter of the tube, so that the second testing plate 12 is in close contact with the inner wall of the tube, eliminating the need for manual adjustment and simplifying the operation process.

[0026] The first detection plate 11 and the second detection plate 12 at the top of the slide plate 5 form a stepped structure. The beveled design at the top of both facilitates the smooth insertion of the quartz tube 2, preventing damage to the quartz tube 2 or affecting detection accuracy due to edge jamming during insertion. The pointer 20 at the bottom of the slide plate 5 is vertically aligned with the second detection plate 12, ensuring that the scale indicated by the pointer 20 corresponds to the actual contact position of the detection plate, guaranteeing accurate readings. The digital display component provides digital measurement results, compensating for potential visual errors in traditional scale readings.

[0027] The rectangular hollow support frame at the bottom of base 1 reduces the overall weight of the device while providing stable support, preventing tilting when placed on a table or floor and affecting detection accuracy. The removable top cover of housing 4 facilitates maintenance or replacement of internal components such as the slide plate 5 and springs, while the open structure provides space for the sliding of slide plate 5 and the extension of the detection plate, ensuring unimpeded movement of components. The overall structural design balances ease of operation, measurement accuracy, and device durability, providing reliable assurance for the inner diameter detection of quartz tube 2.

[0028] In this embodiment, a guide post 8 is fixedly connected inside the housing 4, and a sliding opening 7 is provided in the slide plate 5. The guide post 8 passes through the sliding opening 7, and limit rings 9 are fixedly connected to both ends of the guide post 8. A fixing plate 13 is fixedly connected to the outside of the slide plate 5. The digital display assembly includes a laser rangefinder 14 and a display screen 3. The laser rangefinder 14 is fixedly connected to the fixing plate 13, and the display screen 3 is fixedly mounted on the base 1. A controller is also provided on the base 1. The display screen 3 and the laser rangefinder 14 are electrically connected to the controller. A slot 17 is provided on the slide plate 5, and a pressure plate 15 is slidably connected inside the slot 17. A second spring 19 is connected between the pressure plate 15 and the slot 17. An abutment post 16 is fixedly connected to the bottom of the pressure plate 15, and a pressure sensor 18 is fixedly connected inside the slot 17. The guide post 8 inside the housing 4 passes through the sliding opening 7 of the slide plate 5, providing precise guidance for the sliding of the slide plate 5, ensuring that the slide plate 5 can only move in the horizontal direction, avoiding tilting of the detection plate due to deviation, and ensuring the consistency of measurement data. The limiting rings 9 at both ends of the guide post 8 can limit the sliding range of the slide plate 5 and prevent the slide plate 5 from sliding off the housing 4 due to excessive spring force, thus playing a protective role. The fixing plate 13 on the outside of the slide plate 5 provides a stable mounting base for the laser rangefinder sensor 14, ensuring that the sensor position moves synchronously with the slide plate 5 and guaranteeing the accuracy of the distance measurement.

[0029] In the digital display assembly, the laser rangefinder 14 measures the distance between the two sets of sliding plates 5 by emitting a laser. This distance directly corresponds to the inner diameter of the quartz tube 2. The measurement data is processed by the controller and displayed intuitively on the display screen 3. This method is more accurate than scale readings and reduces human reading errors. The controller, as the core control unit, receives signals from the pressure sensor 18 and controls the laser rangefinder 14 to achieve an automated measurement process.

[0030] Within the slot 17 on the slide plate 5, the pressure plate 15 remains extended upwards under the action of the second spring 19. When the quartz tube 2 is fitted onto the detection plate and pressed downwards, the pressure plate 15 moves downwards under pressure, triggering the pressure sensor 18 via the contact post 16. The pressure sensor 18 transmits a signal to the controller, which then activates the laser rangefinder 14 to ensure that measurement is only performed when the quartz tube 2 is stably in contact with the detection plate, avoiding measurement deviations caused by incomplete fitting and improving detection reliability. The second spring 19 then resets the pressure plate 15 after the pressure disappears, preparing for the next detection. This linkage structure automates the "placement-pressing-measurement" process, reducing manual operation steps and improving detection efficiency.

[0031] The usage method of this embodiment is as follows:

[0032] First, align the quartz tube 2 with the beveled edges of the two sets of second detection plates 12 and gently slip it onto the outside. At this time, the first spring 6 inside the housing 4 pushes the sliding plate 5 outward, causing the second detection plates 12 to come into close contact with the inner wall of the quartz tube 2, ensuring full contact between the detection plates and the tube wall. The operator can quickly read the preliminary value of the inner diameter of the quartz tube 2 through the scale line 10 on the base 1 and the pointer 20 at the bottom of the sliding plate 5, which is suitable for rapid screening or preliminary testing scenarios.

[0033] For more precise digital data, after the quartz tube 2 is in place, gently press down on the top of the quartz tube 2. The bottom of the quartz tube 2 will abut against the pressure plate 15 on the sliding plate 5. The pressure plate 15, under pressure, overcomes the elastic force of the second spring 19 and moves downward, causing the pressure sensor 18 in the groove 17 of the contact post 16 to be pressed. After sensing the pressure, the pressure sensor 18 sends a signal to the controller, which immediately activates the laser rangefinder 14. The laser beam emitted by the sensor accurately illuminates the fixing plate 13 of the other set of sliding plates 5. By measuring the distance between the two sets of sliding plates 5, the precise inner diameter of the quartz tube 2 is obtained. The data is processed by the controller and displayed in real time on the display screen 3, allowing the operator to directly read the precise value. After the test is completed, release the quartz tube 2. The second spring 19 pushes the pressure plate 15 back to its original position, the pressure sensor 18 stops sending signals, the controller shuts down the laser rangefinder 14, and the device returns to standby mode.

[0034] The entire process requires no complicated operation. It can achieve rapid detection via the pointer's 20-degree scale and obtain accurate data via laser ranging, meeting the detection needs of different scenarios. The automated triggering mechanism ensures accurate measurement timing, avoids human error, and significantly improves the efficiency and accuracy of quartz tube inner diameter detection. At the same time, it simplifies the operation process and reduces the skill requirements for operators.
