For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances

[0032] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature.

[0033] Reference Figures 1-6 , an embodiment of the present application provides an objective lens barrel integrated with a light source, including a connector 1, a visible sleeve 2 and an annular lamp 3 arranged axially; the connector 1 includes a first cylinder 11, a second cylinder 12 is connected to the outer periphery of the first cylinder 11, a first external thread connection portion 111 is provided at the first end of the first cylinder 11, and an objective lens (not shown) is connected to the second end of the first cylinder 11; the first end of the visible sleeve 2 is detachably connected to the second cylinder 12, the visible sleeve 2 includes a first sleeve 21 and a second sleeve 22, a first visible window 211 is provided on the side wall of the first sleeve 21, a second visible window 221 is provided on the side wall of the second sleeve 22, and the second sleeve 22 is rotatably sleeved outside the first sleeve 21 to make the positions of the first visible window 211 and the second visible window 221 correspond or stagger; the annular lamp 3 is arranged at the second end of the visible sleeve 2.

[0034] In this embodiment, by rotating the second sleeve 22, the second visible window 221 on the second sleeve 22 can be made to correspond to the first visible window 211 on the first sleeve 21, that is, the first visible window 211 and the second visible window 221 are completely or partially overlapped, so that the objective lens inside the visible sleeve 2 can be observed from the outside. Parameters / models are engraved on the outer wall of the objective lens body, so the parameters / models of the objective lens can be known to avoid confusion; when the objective lens barrel is in normal use, the first visible window 211 on the first sleeve 21 is covered by the second sleeve 22, so that the inside and outside of the visible sleeve 2 are isolated, and the objective lens can work stably.

[0035] In some embodiments, such as Figure 4 and Figure 5As shown, a first annular groove 212 arranged circumferentially is recessed in the outer wall of the first sleeve 21, and a second annular groove 222 arranged circumferentially is recessed in the inner wall of the second sleeve 22. The first annular groove 212 and the second annular groove 222 are in corresponding positions to form a chamber, and a circlip (not shown) is provided in the chamber to realize the relative axial fixation of the first annular groove 212 and the second annular groove 222 and the relative circumferential rotation therebetween.

[0036] In this embodiment, during assembly, the circlip is clamped in the first annular groove 212 on the outer wall of the first sleeve 21. In the natural state of the circlip, the edge of the circlip protrudes from the first annular groove 212; in the contracted state of the circlip, the circlip can be completely retracted into the first annular groove 212, so that the second sleeve 22 can be sleeved on the first sleeve 21. When the second annular groove 222 on the second sleeve 22 corresponds to the first annular groove 212 on the first sleeve 21 in position, the circlip returns to the natural state, so that the inner ring part of the circlip is clamped in the first annular groove 212, and the outer ring part of the circlip is clamped in the second annular groove 222, thereby realizing the relative axial fixation of the first sleeve 21 and the second sleeve 22.

[0037] In some embodiments, as Figure 1 、 Figure 2 shown, a heat dissipation connection cylinder 4 is further included. One end of the heat dissipation connection cylinder 4 is threadedly connected to the first sleeve 21, and the other end of the heat dissipation connection cylinder 4 is connected to the annular lamp 3 by bolts; heat dissipation fins 41 are provided on the outer side of the heat dissipation connection cylinder 4.

[0038] In this embodiment, the heat dissipation connection cylinder 4 is made of a conventional heat dissipation metal material, such as aluminum alloy; the heat dissipation efficiency of the annular lamp 3 is increased through the heat dissipation connection cylinder 4, which is beneficial to avoiding the overheating of the annular lamp 3 and avoiding the situation that the annular lamp 3 has unstable light emission due to serious heating, thereby avoiding affecting the objective lens imaging.

[0039] In some embodiments, as Figure 3 and Figure 6 shown, the second cylinder body 12 is threadedly connected to the first sleeve 21. Thus, the connection head 1 and the visual sleeve 2 are detachably connected, and the objective lens in the connection head 1 can be replaced.

[0040] In some embodiments, as Figure 6As shown, a first internal thread connection portion 112 is provided inside the first cylinder 11. A connection ring 5 is threadedly connected to the first internal thread connection portion 112. A second external thread connection portion 51 is formed on the outer wall of the connection ring 5, and a second internal thread connection portion 52 is formed on the inner wall of the connection ring 5. The second internal thread connection portion 52 is threadedly connected to the objective lens.

[0041] In this embodiment, the objective lens is connected to the connection ring 5. The size of the second internal thread connection portion 52 on the inner wall of the connection ring 5 (i.e., the inner hole diameter of the connection ring 5) is adapted to the threaded connection structure on the objective lens. By replacing the connection ring 5, a connection ring 5 with a suitable inner hole diameter can be selected, so as to adapt to objective lenses of different models and sizes. In this way, without replacing the whole of the connection head 1, only by replacing the connection ring 5, the connection head 1 can be matched and installed with objective lenses of multiple models.

[0042] In some embodiments, as Figure 6 shown, a fastening ring 6 is threadedly connected to the first external thread connection portion 111 of the first cylinder 11. Among them, when the objective lens sleeve of the integrated light source of the present application is applied, the first external thread connection portion 111 on the first end of the connection head 1 is used to connect the microscopic imaging device. The fastening ring 6 can be abutted against the outer wall of the microscopic imaging device to eliminate the thread clearance between the first external thread connection portion 111 and the microscopic imaging device, and avoid the loosening of the connection between the connection head 1 and the microscopic imaging device.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
