DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 As shown, an embodiment of the present invention discloses a fixing device for stabilizing a biological unit, the fixing device comprising: an assembling component 10 and a holding component 20 .

[0034] The retaining assembly 20 includes a cylinder 21, a base plate 22 and a pad 23; a mounting hole is provided on the observation platform (not shown in the drawings), and the lower end of the cylinder 21 passes through the mounting hole and the base plate 22 in sequence and extends below the observation platform; the base plate 22 is fixed to the observation platform by fasteners, and a flange 211 is formed on the outer periphery of the upper end of the cylinder 21, and the pad 23 is arranged between the flange 211 and the base plate 22, and the flange 211 is overlapped on the base plate 22.

[0035] The assembly component 10 includes: a sleeve 12, a base 13, a cover 11, a magnet pair, an annular clamp 14 with an opening, and an annular elastic pad.

[0036] The outer peripheral surface of the base 13 is a cylindrical surface. The base 13 is disposed at the bottom of the cylinder 21 . A set screw 24 is inserted from the outside of the cylinder 21 into the cylinder 21 to fix the base 13 .

[0037] A countersunk hole 131 is formed at the upper end of the base 13, and a plug post 123 is formed at the lower end of the sleeve 12. A damping layer 124 is provided on the outer peripheral surface of the plug post 123. The damping layer 124 can be a rubber layer. The plug post 123 is used to be inserted into the countersunk hole 131, so that the sleeve 12 can rotate relative to the base 13 when subjected to a torsional force, and under the action of the damping layer 124, the sleeve 12 can be maintained at the rotated position.

[0038] A hollow portion is provided in a height area corresponding to the middle of the sleeve 12 and the wall of the cylinder 21, and a force-applying portion 122 is provided in the middle of the sleeve 12. The force-applying portion 122 may be a notch provided on the outer peripheral surface of the sleeve 12. In this way, a human hand can act on the force-applying portion 122 through the hollow portion, thereby rotating the sleeve 12.

[0039] Annular limiting grooves are provided on the outer circumferential surface of the upper part of the base 13 and the outer circumferential surface of the lower part of the sleeve 12. The annular clamp 14 is elastically deformed so that the two protrusions of the annular clamp 14 are respectively embedded in the two annular limiting grooves, thereby realizing a detachable connection between the sleeve 12 and the base 13. Moreover, when a person applies force to rotate the sleeve 12 manually, the sleeve 12 will not tilt or separate from the seat.

[0040] The annular elastic pad can be made of a silicone material and is used to be placed on the matching surface of the upper end of the sleeve 12 , and the glass slide 100 carrying the biological unit 200 is used to be placed on the annular elastic pad.

[0041] An upward annular step 121 is formed on the outer periphery of the sleeve 12. The cover 11 is used to buckle on the upper end of the sleeve 12. The cover 11 has a main body and a barrel 111 formed on the edge of the main body. The middle part of the main body is a hollow structure so that the center of the glass slide 100 and the biological unit 200 are not covered by the cover 11. The magnet pair includes an annular first magnet 151 and an annular second magnet 152. The first magnet 151 is attached to the annular step 121, and the second magnet 152 is attached to the bottom of the barrel 111 of the cover 11. In this way, when the cover 11 is buckled on the sleeve 12, the barrel 111 is sleeved on the top of the sleeve 12. Under the magnetic attraction of the first magnet 151 and the second magnet 152, the main body of the cover 11 is pressed against the edge of the glass slide 100 (at this time, the annular elastic pad produces a certain amount of deformation, which is conducive to limiting the micro-movement of the glass slide 100). Preferably, the first magnet 151 and the second magnet 152 are both made of rubber magnets.

[0042] Based on the above, it can be seen that the advantages of the fixing device for stabilizing the biological unit provided by the present invention are:

[0043] 1. The cover 11 is pressed against the edge of the glass slide 100 by the magnetic force of the two magnets, which not only achieves the purpose of quickly fixing the glass slide 100, but also prevents the glass slide 100 from rotating during the fixing process, thereby enabling the glass slide 100 and its biological unit 200 to obtain a horizontal posture consistent with when placed.

[0044] 2. The annular elastic pad disposed at the upper end of the sleeve 12 can not only provide a certain pre-tightening force for fixing the glass slide 100, but also limit the micro-movement of the glass slide 100, including micro-rotation.

[0045] 3. The sleeve 12 is disposed on the base 13 by means of the pins 123 and the countersunk holes 131 , so that the sleeve 12 can be rotated and adjusted. By rotating the sleeve 12 , the horizontal posture of the glass slide 100 and the biological unit 200 thereof can be adjusted.

[0046] 4. By providing a damping layer 124 on the outer peripheral surface of the plug post 123 or the wall of the counterbore 131 , the sleeve body 12 can be kept at the adjusted angle after the angle is adjusted.

[0047] 5. The sleeve 12 is connected to the base 13 by the cooperation of the annular clamp 14 and the annular limiting groove, which not only enables the sleeve 12 and the base 13 to be detachably connected to facilitate cleaning of the sleeve 12, but also ensures that when a person manually applies force to rotate the sleeve 12, the sleeve 12 will not tilt or separate from the base.

[0048] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
