DETAILED DESCRIPTION

[0042] According to the background, when the experimenters manually dial the objective lens conversion table to switch the observation magnification, the particle matter on the hands is easy to adhere to the objective lens conversion table and the objective lens surface. These particles are extremely difficult to clean once solidified, and will randomly fall off during observation, falling on the surface of the measured object, thereby causing observation misjudgment and measurement error. In the observation process, in order to ensure the timeliness of the business, the experimenter cannot frequently change gloves, and the gloves as consumables will also bring a certain cost. In addition, the particles on the conversion table and the objective lens surface will also have adverse effects on the observation results after solidification and falling off.

[0043] How to reduce the amount of particle matter adhered to the objective lens conversion table is a problem worth discussing.

[0044] In order to solve the above technical problems, in the embodiments of the present disclosure, the microscope assembly comprises: an objective lens conversion table; a connecting piece fixed outside the objective lens conversion table; a dialing piece located outside the connecting piece and connected with the connecting piece, suitable for driving the objective lens conversion table to rotate. By adding the connecting piece to the objective lens conversion table, and connecting the dialing piece to the connecting piece, the objective lens conversion table can be driven to rotate by the dialing piece, and the probability of direct contact with the objective lens conversion table can be reduced during the whole process, thereby reducing the amount of particle matter adhered to the objective lens conversion table.

[0045] In order to make the above-mentioned purposes, features and beneficial effects of the present disclosure more obvious and easy to understand, the specific embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0046] For reference Figures 1 to 2 , Figure 1 The structure of a microscope assembly according to the present disclosure is shown, Figure 2 The structure of a microscope assembly according to the present disclosure is shown. The microscope assembly can include an objective lens conversion table (not shown in the figure), a connecting piece 1 and a dialing piece 2.

[0047] Specifically, the connecting piece 1 is fixed outside the objective lens conversion table, and the dialing piece 2 is located outside the connecting piece 1 and connected with the connecting piece 1, suitable for driving the objective lens conversion table to rotate.

[0048] In actual use, by adding the connecting piece 1 to the objective lens conversion table, and connecting the dialing piece 2 to the connecting piece 1, the objective lens conversion table can be driven to rotate by the dialing piece 2, and the probability of direct contact with the objective lens conversion table can be reduced during the whole process, thereby reducing the amount of particle matter adhered to the objective lens conversion table.

[0049] In some embodiments, the microscope assembly can be adapted to a microscope with an objective lens conversion table, such as an optical microscope, an electron microscope, a digital microscope.

[0050] In some embodiments, the connecting member 1 can include a rubber band 3, an L-shaped plate 4, and a screw rod 5.

[0051] In some embodiments, the rubber band 3 is in a long strip configuration with a certain thickness, which is half or more of the width.

[0052] In some embodiments, the L-shaped plate 4 is firmly installed at one end of the rubber band 3.

[0053] Specifically, two through holes are respectively formed at both ends of the L-shaped plate 4, and two mounting holes are respectively formed at the ends of the rubber band 3, the rubber band 3 is arranged at the open end of the L-shaped plate 4, a fixing shaft (not shown) penetrates the L-shaped plate 4 and the rubber band 3, limiting portions (not shown) provided at both ends of the fixing shaft can stably fix the rubber band 3 and the L-shaped plate 4 together, and the screw rod 5 penetrates the middle of the L-shaped plate 4 and is threadedly connected with the L-shaped plate 4.

[0054] In some embodiments, a threaded sleeve is fixed at the inner side or the outer side of the L-shaped plate 4, and the threaded sleeve is threadedly matched with the screw rod 5.

[0055] In some embodiments, the knob 2 is a lever 6, which is fixed at the end of the screw rod 5 and is integrally formed with the screw rod 5, and the axes of the lever 6 and the screw rod 5 are on the same straight line.

[0056] In some embodiments, the lever 6 is designed with an anti-skid structure, such as a groove or a protruding structure.

[0057] In some embodiments, the lever 6 is made of an aluminum alloy rod structure, which is easy to clean and durable.

[0058] Before using the microscope, the screw rod 5 is loosened, one end of the rubber band 3 is penetrated through the L-shaped plate 4 to form a ring structure, the rubber band 3 is sleeved on the periphery of the objective lens conversion platform and is tightly pulled, and finally the screw rod 5 is tightened to ensure that the rubber band 3 is tightly fixed on the outside of the objective lens conversion platform. When using the microscope, the lever 6 is only rotated to realize the conversion of the objective lens on the objective lens conversion platform. During the whole use process, the gloves do not contact the converter and do not touch the surface of the objective lens, which not only effectively reduces the use amount of consumable gloves, but also improves the convenience of converting the objective lens magnification when observing the microscope, and at the same time, helps to improve the accuracy of the observed morphology.

[0059] Reference Figure 3 , Figure 3A structural schematic diagram of another microscope assembly in the present disclosure is shown.

[0060] In some embodiments, the rubber belt 3 is uniformly formed with a tooth structure 31 on both sides, which is used to contact the objective lens conversion platform to increase damping. Similarly, the surface of the objective lens conversion platform is generally provided with a gear-shaped groove to increase damping. The tooth structure 31 on the rubber belt 3 can match the gear-shaped groove on the objective lens conversion platform.

[0061] It should be noted that in other examples, the lever 6 can also not be fixedly connected with the lead screw 5, and the two can be two independent parts. The lever 6 is fixedly connected with the T-shaped plate 4, and the fixing mode can be welding or threaded connection, etc.

[0062] For better understanding Figure 4 and Figure 5 , Figure 4 A structural schematic diagram of another microscope assembly in the present disclosure is shown, Figure 5 A structural schematic diagram of a connecting piece in the present disclosure is shown.

[0063] In some embodiments, the connecting piece 1 can include a belt 7, a mouth-shaped plate 8, a clamping plate 9, a torsional spring 10 and a handle 11.

[0064] Specifically, the belt 7 is in a long strip shape, and a row of clamping grooves 71 is uniformly formed on the outer side near one end. The size and spacing of the clamping grooves 71 are carefully designed. One end of the belt 7 is fixedly connected to the bottom of the mouth-shaped plate 8, and the other end is cleverly passed through the mouth-shaped plate 8, thereby naturally forming a ring structure that can be precisely fitted on the outside of the objective lens conversion platform. The inner diameter of the ring structure perfectly matches the outer diameter of the objective lens conversion platform to improve the stability and reliability of the connection.

[0065] In some embodiments, the clamping plate 9 is rotatably arranged in the internal space of the mouth-shaped plate 8.

[0066] Specifically, the clamping plate is used to cooperate and match with the clamping grooves 71 on the belt 7. When the clamping plate 9 and the clamping grooves 71 are clamped with each other, a stable connection effect can be provided for the entire connecting piece 1. The torsional spring 10 is precisely installed on the clamping plate 9, and the two ends thereof are respectively in close contact with the clamping plate 9 and the top of the mouth-shaped plate 8, and the torsional spring is always in a compressed state. Under the continuous action of the elasticity of the torsional spring 10, one end of the clamping plate 9 will always be in close contact with the belt 7, so that the clamping between the clamping plate 9 and the clamping grooves 71 is more firm, effectively preventing accidental loosening.

[0067] In some embodiments, the rotating handle 11 is fixedly connected with the rotating shaft (not shown in the figure) of the clamping plate 9 as a whole, and the rotating handle 11 is located outside the mouth plate 8.

[0068] When the connector 1 needs to be adjusted or disassembled, the rotating handle 11 is rotated to drive the clamping plate 9 to rotate through the linkage between the rotating handle 11 and the rotating shaft of the clamping plate 9, so as to smoothly remove the close contact between the clamping plate 9 and the clamping groove 71, and realize the flexible adjustment and convenient disassembly of the connector 1.

[0069] In some embodiments, the actuator 2 can be a lever 6 fixed on the mouth plate 8.

[0070] In some embodiments, the outside of the mouth plate 8 is fixed with a threaded sleeve (not shown in the figure), and the end of the lever 6 is formed with a threaded portion threadedly matched with the threaded sleeve.

[0071] Referring to Figure 6 , Figure 6 The structure of another microscope assembly in the present disclosure is shown.

[0072] In some embodiments, the connector 1 can include a left half clamp 12, a right half clamp 13, and a fastening bolt 14.

[0073] Specifically, one end of the left half clamp 12 is connected to one end of the right half clamp 13 by a hinged manner, forming a structure basis that can be flexibly opened and closed, and the other end of the left half clamp 12 and the right half clamp 13 is fixed by the fastening bolt 14.

[0074] In actual use, by adjusting the relative positions of the two, the left half clamp 12 and the right half clamp 13 are cooperated to accurately enclose a circular structure, so as to fix the objective lens conversion platform inside the circular structure, ensuring the stability and reliability of the installation.

[0075] In some embodiments, the actuator 2 can be a lever 6 fixed on the left half clamp 12 or the right half clamp 13, so as to conveniently exert force and transmit action instructions during subsequent operations.

[0076] In some embodiments, the microscope can further include a rubber pad 15.

[0077] The rubber pad 15 can be located inside the left half clamp 12 and / or the right half clamp 13.

[0078] Specifically, the rubber pad 15 is soft and has good buffering performance. When the objective lens conversion platform is fixed in the clamp, the rubber pad 15 can effectively buffer the friction and collision between the clamp and the objective lens conversion platform, greatly avoiding damage to the objective lens conversion platform due to external force, thereby prolonging the service life of the objective lens conversion platform and ensuring the stability of the normal operation thereof.

[0079] In some embodiments, a plurality of connecting parts are fixed on the left half clamp 12 and the right half clamp 13. For example, four connecting parts are arranged on the clamp in groups of two.

[0080] In some embodiments, the connecting mode between the lever 6 and the connecting part is detachable. For example, the connecting part can be a threaded sleeve, and the lever 6 is screwed with the lever 6. In this way, the flexibility during assembly can be improved.

[0081] In some embodiments, the fastening bolt 14 can be selected from a hand bolt or a disc-shaped bolt.

[0082] Such a selection is based on the consideration of actual use convenience. Both the hand bolt and the disc-shaped bolt can be operated without the aid of special tools. The user can directly tighten or loosen by hand, which greatly improves the operation efficiency of the connecting piece 1 during installation and disassembly.

[0083] In some embodiments, a nut (not shown in the figure) is fixed on the left half clamp 12, and the fastening bolt 14 is threadedly connected with the nut. Correspondingly, an avoiding opening (not shown in the figure) for avoiding the screw part of the fastening bolt 14 is formed on the right half clamp 13.

[0084] When the left half clamp 12 and the right half clamp 13 need to be fixed together, the fastening bolt 14 can be smoothly screwed with the nut through the avoiding opening. The existence of the avoiding opening effectively avoids the installation difficulty problem caused by structural interference, ensures the smoothness of the entire fastening process, and makes the left half clamp 12 and the right half clamp 13 tightly hold together, so as to firmly fix the objective lens conversion platform in the circular structure formed thereby, thereby providing a solid guarantee for the stable operation of the equipment. Of course, the opposite is also true.

[0085] It should be noted that in other examples, the left half clamp 12 and the right half clamp 13 can also exist in a mutually independent split structure, and they are stably connected with each other by means of the fastening bolt 14.

[0086] During installation or disassembly, the left half clamp 12 and the right half clamp 13 can be placed in their respective positions on the objective lens conversion stage. Then, the gap between them can be gradually adjusted and tightened using the fastening bolts 14 until they fit tightly together, forming a complete and stable circular ring structure. This effectively fixes the objective lens conversion stage in place, which not only facilitates the assembly process but also ensures the reliability and stability of the connection, meeting the requirements of the objective lens conversion stage fixing device under different working conditions and usage needs.
