Embodiment
Describe specific embodiment of the utility model in detail below in conjunction with the accompanying drawings.
Specific embodiment 1：Fig. 1, Fig. 3, Fig. 4 illustrate a kind of culture dish coating aid, including a rotatable, card
The gripping mechanism 1 of tight culture dish, the gripping mechanism are three-jaw self-centering chuck, the chuck and the chuck original on lathe
Manage identical, but Material Strength and quality need not be so big, and alloy in lightweight can meets, in order to prevent that culture dish from being pressed from both sides
Broken, claw retaining part 101 is sheet metal, and is flexible metal steel disc, so both reduces cost, and alleviate
Weight；Each claw retaining part 101 is fixed for one end, and the bulge-structure of another end opening, projection is circular arc, rectangle
Or base, parallel to the isosceles trapezoid at the claw back side, the arc range of the arcuate structure is 0.5 π ~ π, and suitable radian makes
Arcuate structure clamping is more stable.The face that each elastic steel sheet is close to culture dish is crush zone 1011, and crush zone is fixed with increasing
The sheet rubber 102 of big frictional force, the sheet rubber are that more than two pieces of block rubber is spliced, and are so designed that, can make clamping
Culture dish is more stable, and culture dish can be prevented to be damaged；The part that the retaining part is not bonded with culture dish is buffering
Area 1010, the buffering area deformation is larger, is bent and deformed the sheet rubber 102 and culture dish outer wall caused on crush zone 1011
Closely, parallel fitting, and because retained part is deformable, can deform, ensure tight as the shape of culture dish is different
It is closely connected to merge clamping.The Elastic Steel length of a film can be 10mm, a width of 5mm.The gripping mechanism can clamping regional extent diameter
For 20mm.The gripping mechanism bottom centre is connected with rotary shaft 2 by bearing 6, and rotary shaft lower end is fixed on the base 3, bottom
Seat makes culture dish coating aid is stable to place.Culture dish coating aid described in the utility model improves coating effect
Rate, effectively reduce the bacterium colony caused by test liquid crawling, the bacterium colony skewness cultivated and count difficulty, and reduce
The errors of count results.
The culture dish coating aid is corresponding with a kind of culture dish based on above-mentioned culture dish coating aid and applied
Cloth method, comprises the following steps：The culture dish equipped with culture medium is clamped on the chuck first, ensures the center of culture dish
Overlapped with the centre of gyration of chuck；The three-jaw self-centering chuck principle is to be machined with plane at the back side of a bevel gear
Archimedes's screw thread, when using 11 rotating chuck of key, conical gear is driven to rotate, Archimedes's screw thread and movable jaw phase
Engagement, scroll chuck is thus set to be moved simultaneously to center, so as to step up workpiece.Then, a hand rotating chuck, finger control
Rotating speed, the hand-held spreading rod for being moistened with test liquid of another are from inside to outside or uniform from outside to inside in media surface even spread
Coating, ensure not holiday.This method improves coating efficiency, improves coating uniformity, and difficulty is counted so as to reduce bacterium colony,
Reduce the error of bacterium colony count results.
Specific embodiment 2：Fig. 2, Fig. 3, Fig. 4 illustrate a kind of culture dish coating aid, including a rotatable, card
The gripping mechanism 1 of tight culture dish, the gripping mechanism is three-jaw self-centering chuck, the chuck and the card being generally used on lathe
Disk principle is identical, but Material Strength and quality need not be so big, and alloy in lightweight can meets, in order to prevent culture dish quilt
It is caught broken；Each claw retaining part 101 is that lower end is fixed on claw and the bulge-structure of upper end open, or lower end are opened
Mouthful and upper end be fixed on bulge-structure on claw, projection is circular arc, rectangle or base parallel to the trapezoidal of the claw back side,
The arc range of the arcuate structure is 0.5 π ~ π, and suitable radian makes arcuate structure clamping more stable.Each projection can
Think elastic steel sheet, if bulge-structure is arc, the face that the elastic steel sheet is close to culture dish is crush zone 1011, and crush zone is solid
Surely there is the sheet rubber 102 of increasing friction force, the sheet rubber is that more than two pieces of block rubber is spliced, and is so designed that, can make
The culture dish of clamping is more stable, and culture dish can be prevented to be damaged；The portion that the retaining part 101 is not bonded with culture dish
It is divided into buffering area 1010, the buffering area is that deformation is larger, is bent and deformed the sheet rubber and culture dish caused on crush zone
Outer wall is close, parallel fitting, and because retained part is deformable, can deform, guarantor as the shape of culture dish is different
Card is brought into close contact and clamped.If isosceles trapezoid, then the Elastic Steel length of a film can be 20mm, a width of 10mm.The clamping dress
Put can clamping a diameter of 100mm of regional extent.The bottom centre of gripping mechanism 1 is fixed with rotary shaft 2, and rotary shaft lower end connects
Joint bearing 6, the bearing can be sliding bearing or rolling bearing, or the device that the support for having axle sleeve and enabling axle to rotate rotates,
And reduction box 4 and motor 5 are connected, the motor is small electric motors, and voltage can be 6 ~ 12V, and reductor can reduce rotating speed, carry
High torque, the motor and reduction box are fixed on the base 3, and base makes culture dish coating aid is stable to place.This practicality
New described culture dish coating aid improves coating efficiency, saves the plenty of time, effectively reduces because of test liquid
Bacterium colony counts difficulty caused by crawling, the bacterium colony skewness cultivated, and reduces the error of count results.
The culture dish coating aid is corresponding with a kind of culture dish based on above-mentioned culture dish coating aid and applied
Cloth method, comprises the following steps：The culture dish equipped with culture medium is clamped on the gripping mechanism first, ensures culture dish
Center overlaps with the centre of gyration of gripping mechanism；The three-jaw self-centering chuck principle is to add at the back side of a bevel gear
Work has plane Archimedes's screw thread, when using 11 rotating chuck of key, drives conical gear to rotate, Archimedes's screw thread and work
Dynamic claw is meshed, and thus makes three to grab chuck and is moved simultaneously to center, so as to step up workpiece.Then, motor switch, electricity are opened
Machine 5 drives rotary shaft 2 and chuck to rotate simultaneously, at this moment, one hold be moistened with test liquid spreading rod it is uniform in media surface
Coating, even spread, ensures not holiday from inside to outside or from outside to inside.Coating efficiency is improved, saves the plenty of time, is improved
Coating uniformity, difficulty is counted so as to reduce bacterium colony, reduces the error of bacterium colony count results.
It is pointed out that above-mentioned preferred embodiment is only to illustrate technical concepts and features of the present utility model, its purpose
It is to allow person skilled in the art to understand content of the present utility model and implements according to this, this reality can not be limited with this
With new protection domain.All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in this reality
Within new protection domain.
