Description

Technical Field

[0001] The present invention relates to the technical field of microscopes, and particularly to a comparison microscope and a virtual simulation experiment system. Background Art

[0002] A comparison microscope is a microscope that simultaneously observes the left and right object fields of view with a set of eyepieces and uses methods such as field cutting, docking, and overlapping to compare two (or more) objects. It can accurately identify the subtle differences or trace correlations between the objects to be compared. It is suitable for use in industries and departments such as banking, archaeology, electronics, biology, and agriculture that require comparison and identification of objects.

[0003] Currently, the comparison microscope cannot perform fixed observations of the object to be observed from multiple angles, nor is it convenient for fixed observations of irregular objects from multiple directions. It is easily restricted by the shape and specifications of the object to be observed, with poor flexibility and convenience in use. Moreover, teaching is usually carried out in the user's professional laboratory, using the method of first explaining and demonstrating and then having the customer actually operate. Due to the unfamiliar operation of the instrument by beginners, damage to the equipment often occurs. Since the comparison microscope is a relatively precise instrument and the price is very expensive, once damaged, it requires professional personnel of the company to repair, which not only affects the teaching progress but also causes losses and waste of national property. At the same time, the teaching location is limited to the professional laboratory, and the teaching content cannot be made into MOOCs or micro-courses, which is not convenient for users to learn anytime and anywhere.

[0004] To solve the above problems, a comparison microscope and a virtual simulation experiment system are proposed. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See Figure 1 A comparison microscope comprises a microscope body 1 and a clamping component 2 arranged at the lower end of the objective lens of the microscope body 1. The clamping component 2 can be used specifically according to the actual object to be observed, or used at the lower end of a single objective lens, or used at both lower ends.

[0038] See Figure 2 、 6And 8, a comparison microscope, the clamping member 2 includes a mounting chassis 21 and a support column 22 disposed at the upper middle of the mounting chassis 21. The upper end of the support column 22 is rotatably connected to the mounting block 24, and the first screw 23 is threaded through the mounting block 24 to contact the upper end of the support column 22 to control stability or rotation, facilitating the adjustment of the rotation angle of the mounting block 24, and facilitating multi-angle penetration comparison of the object to be observed. The mounting block 24 is in the shape of a '7', and an auxiliary clamping member 25 is threadedly disposed at the upper middle of the front end portion. The auxiliary clamping member 25 includes a threaded column 251 and a second screw 253 inserted into the threaded column 251. The threaded column 251 is threadedly connected to the mounting block 24, and the third screw 241 is threaded through the mounting block 24 to contact the threaded column 251 to control adjustment and fixation. A clamping sleeve 252 is disposed at the front end portion of the threaded column 251. Preferably, the clamping sleeve 252 is made of rubber material, and a collar 254 is disposed at the front end of the second screw 253 located in the wall cavity of the clamping sleeve 252. The clamping sleeve 252 is in a conical shape with a larger diameter at the inlet than the inner diameter. The collar 254 is matched with the inner end of the clamping sleeve 252, and the bottom of the inner cavity of the clamping sleeve 252 extends into the collar 254. The clamping sleeve 252 facilitates the preliminary fixation of a small object to be observed, such as the tip of a bullet, while the cooperation between the collar 254 and the clamping sleeve 252 can fix the end portion of a columnar object inserted into the bottom of the clamping sleeve 252, such as the head of a bullet shell. A bottom clamping member 26 is threadedly disposed at the upper end of the mounting block 24 at the lower end of the inlet section of the clamping sleeve 252.

Preferably, the gasket 262 is made of rubber material, and a tapered hole with a larger upper diameter than the lower diameter is formed inside. Four slots are formed on the gasket 262 outside the tapered hole, and the four slots are in a cross shape when viewed from above. For an irregular object, the opposite side of the object to be observed can be inserted into the tapered hole. With the cooperation of the slots and the characteristics of the rubber material, the object to be observed can be fixed, improving the diversity and flexibility of the use of the clamping member 2, and having a simple structure and convenient use.

A small object clamping member 27 is arranged on the plug post 242. The small object clamping member 27 includes an L-shaped block 271 sleeved outside the plug post 242. The L-shaped block 271 is controlled to move forward and backward or be fixed by a fourth screw 272 passing through the L-shaped block 271 in a threaded manner and contacting the plug post 242. A first clamping screw 273 is threaded through the upper end of the L-shaped block 271. When it is necessary to clamp a regular small object, such as a bullet head, one end of the small object is inserted into the clamping sleeve 252, and then through fine adjustment of one end of the L-shaped block 271 and the first clamping screw 273, the small object can be stably clamped, which is convenient for clamping and fixing regular small objects, and further improves the use diversity and flexibility of the clamping member 2.

The large object clamping member 28 includes a protective frame 281 and a plug 282 arranged at one end of the protective frame 281. A second clamping screw 283 is also threaded through the other end of the protective frame 281. An opening with one end being square-shaped and the other end being triangular-shaped is formed in the middle of the protective frame 281. When it is necessary to clamp a regular large object, such as a large bullet shell, first insert the plug 282 into the clamping sleeve 252, then rotate the second screw 253 so that the ferrule 254 squeezes the clamping sleeve 252 to clamp the plug 282, and then insert the large object into the opening and rotate the second clamping screw 283 to clamp the large object, further improving the use diversity and flexibility of the clamping member 2.

[0042] Refer to Figure 11, Another technical solution proposed by the present invention: Provide a virtual simulation experiment system, including a microscope virtual simulation teaching demonstration platform, which can demonstrate and teach functions such as instrument installation and debugging instructions, teaching demonstrations, virtual simulation experiments, experimental operation evaluation, and related management.

A case study module allows the user to further strengthen the use of the comparison microscope through actual cases. Through the study of actual cases, the user can master and flexibly use the operation components and function buttons of the microscope. A case assessment module reduces the occurrence of operation errors when using the microscope in the real environment through assessment during the actual use process.

[0045] Refer to Figure 14 , The case assessment module is used to judge whether trainees can operate flexibly. After learning the case study module, an assessment is conducted. During the assessment, first select the primary examination questions, and then perform step-by-step operations on the questions. When the first operation is an incorrect operation, the system directly controls the return to the previous level. When it is a correct operation, proceed to the next step, and so on. After the trainee completes all operations, the system scores according to the number of returns in the trainee's operation process. Similarly, conduct tests on examination questions of different difficulties. Finally, based on the test scores, it is possible to intuitively understand the trainee's mastery level of the comparison microscope, thereby achieving the flexible operation of the comparison microscope without actual operation comparison.
