Description

Technical Field

[0001] This utility model relates to the field of microscope technology, specifically to a microscope that is easy to inspect and replace. Background Technology

[0002] A microscope is an optical instrument consisting of one or more lenses. It is mainly used to magnify tiny objects, making those that are not directly observable to the naked eye visible. Microscopes have a wide range of applications in the medical, scientific research, and educational fields.

[0003] According to a microscope that is easy to inspect and replace (Announcement No.: CN216528742U), the above application raises the electron microscope to facilitate opening the bottom inspection port of the electron microscope for inspection from the bottom. Illumination can be provided during the inspection process, which is more user-friendly. The illumination area can also be adjusted by changing the position of the illumination lamp.

[0004] However, in actual use, the above-mentioned equipment simply raises the microscope structure from the height of the base, and the space between the bottom of the microscope and the bottom mounting base is still relatively narrow, which restricts the maintenance and repair of the bottom of the microscope and affects the use of the microscope. In view of this, we propose a microscope that is easy to repair and replace. Utility Model Content

[0005] The purpose of this invention is to provide a microscope that is easy to inspect and replace, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a microscope that is easy to inspect and replace, comprising a base, a support frame fixedly mounted on the upper surface of the base, a mounting plate movably mounted on the outer wall of the support frame near the center of the base, a microscope body fixedly mounted on the side wall of the mounting plate, and a flipping assembly provided inside the support frame, the flipping assembly comprising:

[0007] A drive motor is fixedly installed on the bottom inner wall of the support frame. An adjusting screw is fixedly installed at the output end of the drive motor. A threaded sleeve is threadedly connected to the outer wall of the adjusting screw. The side wall of the threaded sleeve is rotatably connected to the side wall of the mounting plate. A guide groove is provided on the outer wall of the support frame near the center of the base.

[0008] The lower connecting rod is rotatably mounted on the outer wall of the mounting plate near the support frame. A lower L-shaped piece is hinged to the outer wall of the lower connecting rod. An upper connecting rod is rotatably mounted on the outer wall of the mounting plate near the support frame. An upper L-shaped piece is hinged to the end of the upper connecting rod.

[0009] A transmission rod is rotatably mounted on the inner top wall of the lower L-shaped part. A threaded slider is slidably mounted on the inner top wall of the lower L-shaped part. A tension spring is fixedly connected between the upper surface of the threaded slider and the bottom end face of the upper L-shaped part. A spiral groove is opened on the arc-shaped outer wall of the top of the transmission rod. A convex ball is fixedly mounted on the inner bottom wall of the upper L-shaped part.

[0010] Preferably, the outer diameters of the upper connecting rod and the lower connecting rod are adapted to the inner diameter of the guide groove, so that when the mounting plate moves vertically along the side wall of the support frame, the upper connecting rod and the lower connecting rod can slide along the inside of the guide groove.

[0011] Preferably, a rectangular groove adapted to the bottom end of the upper L-shaped part is provided on the top inner wall of the lower L-shaped part, and the upper L-shaped part and the lower L-shaped part maintain a relatively sliding connection relationship.

[0012] Preferably, the guide groove includes a vertical section and an arc-shaped section. The vertical section is located at the vertical central axis of the support frame and is vertically oriented. The arc-shaped section is located at the top of the vertical section.

[0013] Preferably, a limiting component is provided on the arc-shaped outer wall of the upper connecting rod. The limiting component includes a shrinkage groove, which is formed on the arc-shaped outer wall of the upper connecting rod. A contact strip is slidably connected to the inner wall of the shrinkage groove. A small spring is fixedly connected to the lower surface of the contact strip. A corrugated strip is provided on the upper surface of the contact strip. An arc-shaped protrusion is provided on the lower surface of the arc-shaped section of the guide groove.

[0014] Preferably, the number of arc-shaped protrusions is set to multiple sets, and the multiple sets of arc-shaped protrusions are evenly distributed on the lower surface of the arc-shaped section of the guide groove. Thus, after the mounting plate drives the microscope body to rotate to a certain angle, the upper connecting rod is positioned between the arc-shaped protrusions by the restriction of the arc-shaped protrusions.

[0015] Compared with the prior art, this utility model provides a microscope that is easy to inspect and replace, and has the following beneficial effects:

[0016] 1. This microscope, which is easy to inspect and replace, is equipped with a flipping component. The movement of the upper and lower connecting rods along the inner wall of the guide groove causes the mounting plate to deflect after moving upwards a certain distance, completing the flipping of the microscope body. Simultaneously, the upward displacement of the upper L-shaped component, in conjunction with the convex ball and spiral groove, drives the transmission rod, causing the threaded slider to tighten the tension spring. This creates a triangular force-bearing structure between the upper and lower connecting rods on the side of the mounting plate, and the connection point between the mounting plate and the threaded sleeve, ensuring the stability of the mounting plate on the support frame and facilitating the inspection and maintenance of the microscope body.

[0017] 2. This microscope, which is easy to inspect and replace, is equipped with a limiting component. After the microscope body is rotated to a certain angle by the mounting plate, the upper connecting rod is positioned between the arc-shaped protrusions by the limiting component. At the same time, the small spring pushes the contact strip outward to the gap between the arc-shaped protrusions, so as to promote the relative stability of the upper connecting rod within the arc-shaped section of the guide groove. This, together with the locking between the upper L-shaped component and the lower L-shaped component, further ensures the stability of the mounting plate and the microscope body after the angle is adjusted, making it convenient for staff to inspect and maintain.

[0026] like Figures 1-7As shown, this utility model provides a technical solution: a microscope that is easy to repair and replace, including a base 1, a support frame 2 fixedly installed on the upper surface of the base 1, an installation plate 3 movably installed on the outer wall of the support frame 2 near the center of the base 1, a microscope body 4 fixedly installed on the side wall of the installation plate 3, and a flipping assembly 5 provided inside the support frame 2. The flipping assembly 5 includes a drive motor 51, an adjusting screw 52, ​​a threaded sleeve 53, a guide groove 54, a lower connecting rod 55, a lower L-shaped part 56, an upper connecting rod 57, an upper L-shaped part 58, a transmission rod 59, a threaded slider 512, a tension spring 513, a spiral chute 510, and a convex ball 511.

[0027] In one embodiment of this utility model, a drive motor 51 is fixedly installed on the bottom inner wall of the support frame 2. An adjusting screw 52 is fixedly installed at the output end of the drive motor 51. A threaded sleeve 53 is threadedly connected to the outer wall of the adjusting screw 52. The side wall of the threaded sleeve 53 is rotatably connected to the side wall of the mounting plate 3. A guide groove 54 is provided on the outer wall of the support frame 2 near the center of the base 1. A lower connecting rod 55 is rotatably installed on the outer wall of the mounting plate 3 near the support frame 2. A lower L-shaped piece 56 is hinged to the outer wall of the lower connecting rod 55. The mounting plate 3... An upper connecting rod 57 is rotatably mounted on the outer wall near the support frame 2. An upper L-shaped piece 58 is hinged to the end of the upper connecting rod 57. A transmission rod 59 is rotatably mounted on the inner wall of the top of the lower L-shaped piece 56. A threaded slider 512 is slidably mounted on the inner wall of the top of the lower L-shaped piece 56. A tension spring 513 is fixedly connected between the upper surface of the threaded slider 512 and the bottom end face of the upper L-shaped piece 58. A spiral groove 510 is opened on the top arc-shaped outer wall of the transmission rod 59. A convex ball 511 is fixedly mounted on the inner wall of the bottom end of the upper L-shaped piece 58.

[0028] Furthermore, two sets of support frames 2 are provided, and the two sets of support frames 2 are symmetrically arranged about the vertical central axis of the base 1 to ensure the stability of the microscope body 4 on the base 1. At the same time, the connection between the threaded sleeve 53 and the mounting plate 3 is located inside the guide groove 54, so that the movement of the threaded sleeve 53 on the mounting plate 3 will not be interfered with. In addition, the outer diameters of the upper connecting rod 57 and the lower connecting rod 55 are adapted to the inner diameter of the guide groove 54, so that when the mounting plate 3 moves vertically along the side wall of the support frame 2, the upper connecting rod 57 and the lower connecting rod 55 can slide along the inside of the guide groove 54 without interference. Specifically, a rectangular groove adapted to the bottom end of the upper L-shaped part 58 is opened on the top inner wall of the lower L-shaped part 56. The upper connecting rod 57 and the lower L-shaped part 56 maintain a relatively sliding connection, so that when the mounting plate 3 moves upward, the upper connecting rod 57 and the lower connecting rod 55 on its side can cooperate with the upper L-shaped part 58 and the lower L-shaped part 56 that are hinged to each other to slide relative to each other without getting stuck. Specifically, the guide groove 54 includes a vertical section and an arc section. The vertical section is located at the vertical central axis of the support frame 2 and is vertically arranged. At the same time, the arc section is located at the top of the vertical section and the top of the arc section faces the rear side of the base 1. This causes the upper connecting rod 57 moving along the guide groove 54 to drive the mounting plate 3 to deflect backward, so that the mounting plate 3 drives the microscope body 4 to deflect, thereby exposing the bottom space of the microscope body 4, which facilitates the staff to inspect and maintain the microscope body 4.

[0029] Meanwhile, a circular hole adapted to the outer diameter of the transmission rod 59 is provided on the inner wall of the bottom end of the upper L-shaped part 58, and a convex ball 511 is provided on the inner surface of the circular hole. The convex ball 511 is also provided inside the spiral chute 510. Thus, during the relative sliding between the upper L-shaped part 58 and the lower L-shaped part 56, the vertical sliding of the convex ball 511 will cause the transmission rod 59 to rotate. In addition, a threaded groove is provided on the bottom arc-shaped outer wall of the transmission rod 59, which is threadedly connected to the threaded slider 512. This allows the rotation of the transmission rod 59 to cause the threaded slider 512 to slide vertically along the top inner wall of the lower connecting rod 55, thereby changing the tension of the tension spring 513. After the mounting plate 3 rotates, the tension spring 513 tightly pulls the upper L-shaped part 58, ensuring that the mounting plate 3 and the microscope body 4 maintain high stability after flipping, so that the staff can maintain and repair the microscope body 4.

[0030] In addition, a limiting component 6 is provided on the arc-shaped outer wall of the upper connecting rod 57. The limiting component 6 includes a shrinkage groove 61, which is opened on the arc-shaped outer wall of the upper connecting rod 57. A contact strip 62 is slidably connected to the inner wall of the shrinkage groove 61. A small spring 63 is fixedly connected to the lower surface of the contact strip 62. A corrugated strip 64 is provided on the upper surface of the contact strip 62. An arc-shaped protrusion 65 is provided on the lower surface of the arc-shaped section of the guide groove 54.

[0031] In this embodiment of the invention, multiple sets of shrinkage grooves 61 are provided, and these multiple sets of shrinkage grooves 61 are evenly distributed in a circumferential array on the arc-shaped outer wall of the upper connecting rod 57. Furthermore, the shrinkage grooves 61 and the guide grooves 54 are located in the same plane. Further, the top surface of the contact strip 62 is formed into an arc shape to better fit the inner wall of the top arc-shaped section of the guide groove 54. Simultaneously, the small spring 63 initially pushes the contact strip 62 out of the shrinkage groove 61, thereby allowing it to better contact the arc-shaped protrusions 65. Additionally, the corrugated belt 64 is made of rubber to increase the contact efficiency between the contact strip 62 and the guide groove 54. Specifically, the number of arc-shaped protrusions 65 is set as follows: Multiple sets of arc-shaped protrusions 65 are evenly distributed on the lower surface of the arc-shaped section of the guide groove 54. After the mounting plate 3 drives the microscope body 4 to rotate to a certain angle, the upper connecting rod 57 is positioned between the arc-shaped protrusions 65 by the constraint of the arc-shaped protrusions 65. At the same time, the small spring 63 causes the contact strip 62 to push outward to the gap between the arc-shaped protrusions 65, so as to promote the relative stability of the upper connecting rod 57 within the arc-shaped section of the guide groove 54. This, together with the locking between the upper L-shaped part 58 and the lower L-shaped part 56, further ensures the stability of the mounting plate 3 and the microscope body 4 after the angle is adjusted, making it convenient for staff to perform inspection and maintenance.

[0032] In this invention, when the microscope body 4 needs to be inspected and maintained, the drive motor 51 is started, and the adjusting screw 52 is used to make the threaded sleeve 53 drive the mounting plate 3 to move vertically upward along the inner wall of the support frame 2. Through the guidance and restriction of the vertical and arc-shaped sections of the guide groove 54, the mounting plate 3 will deflect after moving upward a certain distance until the upper connecting rod 57 moves to the top of the arc-shaped section, thus completing the flipping of the microscope body 4 and exposing enough working space for the staff to inspect and maintain it. At the same time, the upward displacement of the upper L-shaped part 58, in conjunction with the convex ball 511 and the spiral chute 510, drives the transmission rod 59, so that the threaded slider 512 tightens the tension spring 513. This forms a triangular force structure between the upper connecting rod 57, the lower connecting rod 55 and the connection point between the mounting plate 3 and the threaded sleeve 53 on the side of the mounting plate 3, ensuring the stability of the mounting plate 3 on the support frame 2, so as to facilitate the inspection and maintenance of the microscope body 4.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
