[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It is understandable that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for ease of description, only the parts related to the utility model rather than all structures are shown in the drawings. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] See also Figures 1 to 4 The special dish for droplet culture of the utility model comprises a culture dish body 1 and a supporting mechanism 2.

[0027] The culture dish body 1 is made of glass or polyethylene, and the user can observe the mark on the indicator strip 203 through the culture dish body 1 to determine the properties of the droplet in the groove 101 .

[0028] In addition, a plurality of grooves 101 evenly distributed around the inner bottom of the culture dish body 1 are formed, and the grooves 101 are used to store liquid droplets, thereby fixing the size and position of the liquid droplets. During the process of covering with mineral oil and taking and placing the culture dish body 1, the liquid droplets are not prone to fusion and dislocation.

[0029] Preferably, the groove 101 can be set to different specifications according to needs.

[0030] See also Figures 1 to 4 The supporting mechanism 2 is arranged at the lower side of the culture dish main body 1 , and the supporting mechanism 2 is used to support the culture dish main body 1 .

[0031] The supporting mechanism 2 comprises a base 201, a rotating shaft 202 is rotatably connected to the base 201, an inserting column is fixedly connected to the rotating shaft 202, and an inserting groove matching the inserting column is provided at the outer bottom of the culture dish body 1.

[0032] By inserting the insertion column into the insertion groove, the culture dish body 1 and the base 201 can be installed, which is convenient for operation. At the same time, the culture dish body 1 and the base 201 in the present application are separable, so that the support mechanism 2 as a whole can be applied to culture dish bodies 1 of different models, expanding the application range of the support mechanism 2 as a whole, and also improving the utilization rate of the support mechanism 2.

[0033] Preferably, the diameter of the base 201 is smaller than the diameter of the culture dish body 1 , so as to facilitate the engagement of the fixing rod 206 , so that the culture dish body 1 and the base 201 are not prone to relative rotation.

[0034] In addition, the insertion column is in the shape of a polygonal column. When the culture dish body 1 needs to be rotated, the culture dish body 1 and the base 201 can be relatively rotated by the cooperation of the insertion column and the rotating shaft 202 .

[0035] Specifically, a plurality of indicator strips 203 evenly distributed around a circumference are connected to the upper end surface of the base 201 . The indicator strips 203 correspond to the grooves 101 . Number plates are attached to the indicator strips 203 to indicate the properties of the liquid droplets in the grooves 101 .

[0036] Since the culture dish body 1 and the base 201 of the present application can rotate relative to each other, different indicator bars 203 can be used to number the same groove 101, thereby improving the flexibility of the groove 101 when used and facilitating use by users.

[0037] See also Figures 1 to 4 A fixing plate 204 is provided on one side of the base 201, and a suction cup 205 is installed on the fixing plate 204, and the fixing plate 204 is adsorbed on the outer bottom of the culture dish body 1 through the suction cup 205. By setting the suction cup 205, the fixing plate 204 can be separated from the culture dish body 1, that is, when the culture dish body 1 is separated from the base 201, the fixing plate 204 can be removed from the culture dish body 1, and the fixing plate 204 can be installed on the bottom of another culture dish body 1, thereby improving the overall utilization rate of the fixing plate 204.

[0038] Among them, a fixing rod 206 is slidably provided in the fixing plate 204. Through the contact between the fixing rod 206 and the elastic ring 210, the culture dish body 1 and the base 201 can be locked and fixed, so that the indicator bar 203 can be used to indicate the properties of the droplets in the groove 101, and confusion is not likely to occur.

[0039] In addition, a movable groove 207 is provided in the fixed plate 204, and a side wall of the fixed rod 206 located in the movable groove 207 is connected to a limiting ring 208. A spring 209 is provided in the movable groove 207, and the spring 209 is arranged on the outside of the fixed rod 206. Through the cooperation between the limiting ring 208 and the spring 209, the fixed rod 206 is in contact with the elastic ring 210 in a natural state, and then the culture dish body 1 and the base 201 can be locked and fixed. The user can observe the mark on the indicator bar 203 through the culture dish body 1 to determine the properties of the droplets in the groove 101, and confusion is not easy to occur.

[0040] Specifically, an elastic ring 210 is embedded in the side wall of the base 201, and the elastic ring 210 is made of rubber. The elastic ring 210 cooperates with the fixing rod 206 to lock and fix the culture dish body 1, so that when the groove 101 stores droplets, the culture dish body 1 is not easy to rotate, so as to ensure that the droplets in the groove 101 correspond to the marks on the indicator strip 203, and it is not easy to cause confusion.

[0041] The present application arranges the groove 101 to control the size and position of the droplets, and prevents the droplets from merging and misaligning during the process of covering with mineral oil and taking and placing the culture dish body 1, thereby ensuring the culture and observation effect of the droplets.

[0042] Since the culture dish body 1 and the base 201 can rotate relative to each other, it is convenient for the user to number the liquid droplets in the groove 101 differently, thereby improving the flexibility of the liquid droplet numbering.

[0043] Through the cooperation between the fixing rod 206 and the elastic ring 210 , the positions of the base 201 and the culture dish body 1 can be locked and fixed, so that the user can determine the properties of the droplets in the groove 101 without confusion.

[0044] Through the cooperation between the insertion column and the insertion groove, and the setting of the suction cup 205, the culture dish body 1 can be separated from the support mechanism 2, so that the support mechanism 2 as a whole can be suitable for different culture dish bodies 1, thereby improving the overall utilization rate of the support mechanism 2.

[0045] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present utility model.
