[0002] An inverted fluorescence microscope is a microscope in which the positions of the objective lens, condenser, and light source are reversed compared to a general microscope. It is an organic combination of fluorescence accessories and a microscope. The excitation light is projected downward from the objective lens to the specimen surface, reflected into the objective lens and focused on the sample. The fluorescence generated by the sample and the excitation light reflected by the objective lens surface and the coverslip surface enter the objective lens at the same time. The excitation light and fluorescence are separated by a two-color beam splitter to form an image. The working distance of the objective lens and condenser is very long, and microscopic observation and research of the objects under inspection in the culture dish can be carried out directly. It is suitable for soil microbial culture experiments and has the characteristics of microscopic observation in culture bottles or culture dishes. It can observe transparent living objects without staining and is particularly suitable for microscopic observation of living cells and cell in vitro culture.

[0003] Existing connection devices for inverted fluorescence microscopes are not convenient for assembly and disassembly. For example, a connection device for an inverted fluorescence microscope that is easy to maintain, as described in Patent Publication No. CN215116962U, includes an inverted fluorescence microscope body, a mounting base, a support plate, and a clamping block. During assembly and disassembly, the aforementioned patent requires turning a handle and pulling a pull plate while simultaneously lifting the support plate.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-3 A connection device for an inverted fluorescence microscope includes a support plate 1 and two fixing bases 2, one on each side of the support plate 1. The two fixing bases 2 are fixedly mounted on either side of the objective lens of the inverted fluorescence microscope. Fixing posts 3 are fixedly connected to both sides of one end of the support plate 1, and positioning holes 4 are formed on both sides of the other end of the support plate 1.

[0025] A fixing groove 5 for placing the fixing column 3 is provided at one end of the top surface of the fixing seat 2, and a sliding groove 6 that matches the positioning hole 4 is provided on the other end of the fixing seat 2 facing the side of the supporting plate 1. A positioning block 7 is provided for horizontal sliding in the sliding groove 6, and the upper part of the end of the positioning block 7 facing the positioning hole 4 is inclined. The design of the inclined surface makes it easy to drive the two positioning blocks 7 away from each other by simply pressing down the supporting plate 1 during assembly, thereby improving assembly efficiency. A spring 8 is provided between the positioning block 7 and the sliding groove 6. The spring 8 is always in a compressed state during use, thereby applying a force to the positioning block 7 that is always directed toward the positioning hole 4. The upper end of the positioning block 7 should extend above the fixing seat 2 to facilitate personnel to operate the positioning block 7.

[0026] A movable groove 9 is provided below the sliding groove 6, and the movable groove 9 is connected to the sliding groove 6. A support block 10 is provided in the movable groove 9 for sliding up and down. The support block 10 is L-shaped, and the horizontal end of the support block 10 extends to the bottom of the support plate 1. A tension rope 11 is fixedly connected to the side of the positioning block 7 facing away from the positioning hole 4, and the other end of the tension rope 11 is fixedly connected to the top surface of the support block 10.

[0027] Reference Figure 2-4To assemble the support plate 1, simply align the two fixing posts 3 on the support plate 1 with the fixing slots 5 on the fixing base 2. The lower sides of the fixing posts 3 now mate with the lower sides of the fixing slots 5, effectively positioning one side of the support plate 1. Then, rotating the support plate 1 causes one end of the support plate 1 to move downward, driving a positioning block 7 to compress a spring 8. Once the positioning block 7 is in position with the positioning hole 4, the spring 8 forces the positioning block 7 into the positioning hole 4, effectively positioning the other side of the support plate 1.

[0028] To disassemble the support plate 1, simply simultaneously drive the two positioning blocks 7 away from each other. Once the two positioning blocks 7 are free from the positioning holes 4, the tension cord 11 is relaxed. Continue driving the two positioning blocks 7 away from each other until the tension cord 11 becomes taut and drives the support block 10 upward. The support block 10 then rotates the support plate 1 upward until the positioning blocks 7 and the positioning holes 4 become misaligned. Then, release one of the positioning blocks 7 and continue rotating the support plate 1. Once this is complete, the fixing post 3 at the other end of the support plate 1 can be removed by lifting it upward from the fixing slot 5.

[0029] Reference Figure 1 、 Figure 5 The lower two sides of the fixing groove 5 are in contact with the fixing column 3. In order to facilitate the insertion of the fixing column 3 into the fixing groove 5 during assembly, the top two sides of the fixing groove 5 are chamfered.

[0030] To further enhance the positioning of the support plate 1 by the fixing slot 5 and the fixing block, an arcuate auxiliary slot 12 is defined in the lower portion of the fixing slot 5 on the side facing away from the sliding slot 6. An auxiliary block 13 is fixedly connected to the side of the fixing column 3 and inserted into the auxiliary slot 12. When the support plate 1 is positioned, the positioning block 7 is fully inserted into the positioning hole 4, and the auxiliary block 13 fits against the arcuate upper end of the auxiliary slot 12.

[0031] Reference Figure 3-4 The positioning block 7 can be connected to the sliding groove 6 by horizontal sliding through the first sliding rail, and the problem of unstable movement of the positioning block 7 at the connection point between the sliding groove 6 and the movable groove 9 can be avoided by limiting the first sliding rail.

[0032] In order to prevent the positioning block 7 and the tension rope 11 from being squeezed or cut, a first groove 14 for the tension rope 11 to pass through is provided at the bottom of the positioning block 7, and the side edges of the first groove 14 are rounded.

[0033] In order to further improve the service life of the tension rope 11, a pulley 15 is provided between the sliding groove 6 and the movable groove 9 to cooperate with the tension rope 11, and the top of the pulley 15 is not higher than the top surface of the first groove 14, thereby improving the service life and stability of the device.

[0034] When the positioning block 7 is inserted into the positioning hole 4, the support block 10 is at the lowest point of its travel, and the top surface of the horizontal end of the support block 10 is in contact with the bottom surface of the support plate 1. In this way, the support block 10 can provide an upward supporting force after the support plate 1 is positioned, preventing the support plate 1 from continuing to rotate downward when under great pressure and damaging parts. The support block 10 can be connected to the movable groove 9 by sliding up and down via the second slide rail. In this way, the support force of the support block 10 on the support plate 1 is provided by the limit at the bottom end of the second slide rail.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
