Description

Technical Field

[0001] This utility model relates to the field of microscopic equipment technology, and in particular to a microscopic device for observing the cross-section of a broken needle. Background Technology

[0002] A microscope is an optical instrument consisting of one or more lenses, and it is a hallmark of humanity's entry into the atomic age. Microscopes are primarily used to magnify tiny objects visible to the naked eye. Microscopes are divided into optical microscopes and electron microscopes: the optical microscope was first invented in 1590 by the Dutchman Jansen. Modern optical microscopes can magnify objects up to 1600 times, with a minimum resolution of half the wavelength. The mechanical tube length of domestically produced microscopes is generally 160 millimeters.

[0003] During the production process, fabrics are typically subjected to microscopic observation of the cut surfaces of broken needles. However, existing microscopic devices generally do not have a device to fix the cut surfaces of the fabric, causing the fabric to move during observation and affecting the accuracy of the results. On the other hand, some microscopic devices that do have fixing devices have complex installation and removal processes, reducing the overall adaptability of the device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By moving multiple threaded rods inside multiple internal threaded tubes, the multiple threaded rods push the pressure ring downwards, causing the pressure ring to contact the fabric, thereby fixing the fabric and ensuring the stability of the fabric during observation. This invention provides a microscopic device for observing the cross-section of broken needles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A microscopic device for observing the cross-section of a broken needle includes a microscope, a worktable on the inner wall of the microscope, a placement groove on the upper end of the worktable, a pressure ring above the placement groove, a mounting ring on the upper end of the worktable, a moving mechanism for moving the pressure ring on the inner wall of the mounting ring, two symmetrically arranged fixing plates on the upper end of the mounting ring, and a driving mechanism for driving multiple moving mechanisms between the two fixing plates.

[0007] Preferably, the moving mechanism includes a plurality of symmetrically arranged fixing blocks on the inner wall of the mounting ring, each fixing block having an internally threaded tube rotatably connected through it, each internally threaded tube having a threaded rod passing through it, and the lower ends of each threaded rod being fixedly connected to the upper end of the pressure ring.

[0008] Preferably, the driving mechanism includes two symmetrically arranged rotating rods that are rotatably connected between two fixed plates. The outer walls of both ends of the two rotating rods are provided with worm gears, and the outer walls of the plurality of internally threaded tubes are provided with worm wheels that cooperate with the worm gears.

[0009] Preferably, both of the rotating rods are provided with pulleys on their outer walls, and the two pulleys are connected by a belt drive.

[0010] Preferably, one of the rotating rods has a handwheel at its end, the handwheel has a handle on its outer wall, and the handle has a rubber anti-slip layer on its outer wall.

[0011] Preferably, the upper end of the mounting ring is provided with a plurality of symmetrically arranged fixing bolts, and the number of the plurality of fixing bolts is four.

[0012] The beneficial effects of this utility model are:

[0013] 1. By moving multiple threaded rods within multiple internal threaded tubes, the multiple threaded rods push the pressure ring downwards, causing the pressure ring to contact the fabric, thereby fixing the fabric and ensuring its stability during observation.

[0014] 2. The device can be disassembled and installed on the workbench by means of multiple fixing bolts connecting the mounting ring and the workbench, which facilitates the disassembly and installation of the device in the future and improves the overall adaptability of the device.

[0021] Reference Figure 1-3 A microscopic device for observing the cross-section of a broken needle includes a microscope 1, a worktable 2 on the inner wall of the microscope 1, a placement groove 3 on the upper end of the worktable 2, a pressure ring 10 above the placement groove 3, and a mounting ring 4 on the upper end of the worktable 2. The inner wall of the mounting ring 4 is provided with a moving mechanism for moving the pressure ring 10. The moving mechanism includes multiple symmetrically arranged fixing blocks 7 on the inner wall of the mounting ring 4. Each fixing block 7 is rotatably connected to an internally threaded tube 8, and each internally threaded tube 8 is connected to a threaded rod 9. The lower ends of each threaded rod 9 are fixedly connected to the upper end of the pressure ring 10. By moving the multiple threaded rods 9 within the multiple internally threaded tubes 8, the multiple threaded rods 9 push the pressure ring 10 downward, causing the pressure ring 10 to contact the fabric, thereby fixing the fabric and ensuring the stability of the fabric during observation.

[0022] The upper end of the mounting ring 4 is provided with two symmetrically arranged fixing plates 6. Between the two fixing plates 6 is a driving mechanism for driving multiple moving mechanisms. The driving mechanism includes two symmetrically arranged rotating rods 12 that are rotatably connected between the two fixing plates 6. Both ends of the two rotating rods 12 are provided with worm gears 13. The outer walls of multiple internally threaded tubes 8 are provided with worm wheels 11 that cooperate with the worm gears 13.

[0023] Both rotating rods 12 have pulleys 14 on their outer walls, and the two pulleys 14 are connected by belt drive.

[0024] One of the rotating rods 12 has a handwheel 15 at its end. The outer wall of the handwheel 15 has a handle, and the outer wall of the handle is covered with a rubber anti-slip layer.

[0025] The upper end of the mounting ring 4 is provided with a number of symmetrically arranged fixing bolts 5. There are four fixing bolts 5. Through the connection between the mounting ring 4 and the workbench 2, the device can be disassembled and installed with the workbench 2, which facilitates the disassembly and installation of the device in the future and improves the overall adaptability of the device.

[0026] When using this invention, to observe the cut surface of a broken needle, the fabric with the broken needle cut surface is placed in the placement groove 3. The handwheel 15 is turned, causing one of the rotating rods 12 to rotate. Under the transmission action of the pulley 14 and belt between the two rotating rods 12, the two rotating rods 12 rotate, thereby causing multiple worm gears 13 on the outer wall of the two rotating rods 12 to rotate. By cooperating with the worm wheel 11, multiple internal threaded tubes 8 rotate. By the threaded connection between the internal threaded tubes 8 and the threaded rods 9, the multiple threaded rods 9 move within the multiple internal threaded tubes 8, thereby causing the multiple threaded rods 9 to push the pressure ring 10 down, so that the pressure ring 10 contacts the fabric, thereby fixing the fabric and ensuring the stability of the fabric during observation.

[0027] The device can be disassembled and installed on the workbench 2 by means of multiple fixing bolts 5 between the mounting ring 4 and the workbench 2, which facilitates the disassembly and installation of the device in the future and improves the overall adaptability of the device.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
