Description
Technical field
The present invention relates to desk centrifuge, specifically a kind ofly be used for laying and fixing, that can regulate height, the centrifuge tube coating device of placing centrifuge tubes with different diameters simultaneously of centrifuge tube on the desk centrifuge.
Background technology
Work such as all kinds of chemical examinations, biochemical test, classification sample need be done by departments such as the R﹠D institution of current society, hospital, chemical industry, food, need centrifuge.Centrifuge has several around the cylinder that axis own rotates at a high speed, is called rotary head, usually by Motor Drive.After suspension (or emulsion) adds rotary drum, rotated with speed by rapid the drive with rotary drum, each component is separated under centrifugal action, and discharges respectively.Usually, the rotary drum rotating speed is high more, and separating effect is also good more.
Circular well-bucket, outer tube and the centrifuge tube of existing desk centrifuge rotary head generally have fixing diameter, and research fields such as soil, biology, centrifugal reagent needs the consumption difference.Therefore,, need differing heights and the centrifuge tube of diameter to hold the reagent of different amounts if think the reagent of centrifugal different content, thereby, need to design the outer tube of differing heights and diameter.The circular well-bucket of existing desk centrifuge places on the rotor of centrifuge, and outer tube places in the circular well-bucket, and centrifuge tube places in the outer tube; And the position of placing centrifuge tube on the outer tube only has 2-3 usually, can not satisfy the efficient mensuration of batch samples.
Summary of the invention
The purpose of this invention is to provide a kind of laying and fixing, that can regulate height, the outer tube of placing centrifuge tubes with different diameters simultaneously of centrifuge tube on the desk centrifuge that be used for, it can improve the centrifuge service efficiency, make full use of the circular well-bucket of centrifuge space, and make simply, easy to use, be easy to safeguard and promote.
For achieving the above object, the technical solution used in the present invention is as follows:
Be used to settle the outer tube of centrifuge tube on a kind of desk centrifuge, it can be used for the fixedly centrifuge tube of the different height of different-diameter.
Comprise 1 chassis, identical shaped and big or small pallet, the cylinder-shaped sleeve of two end openings more than 1 or 1, alignment pin and aperture adjustment pad;
Evenly offer the circular hole of 5 or 5 above same diameter on described each pallet respectively, be fixed with sleeve pipe in the circular hole, and the height of the sleeve pipe on the same pallet is identical and their upper open ends and lower open end are in the same plane respectively;
When pallet is 1 when above, the circular hole position that is provided with on the pallet is corresponding and big or small identical;
The chassis is identical with the shape and the size of pallet, pallet more than 1 or 1 is stacked on the chassis successively, and on each pallet, all stacked aperture spacer sheet, on chassis, pallet and aperture adjustment pad, be provided with the locating hole more than 3 or 3 respectively symmetrically, and locating hole has the position corresponding mutually, and alignment pin is set in the locating hole chassis and pallet locking;
Described aperture adjustment pad is and the PVC disk of the same size of pallet, and symmetry offers circular aperture on it, and the position of sleeve pipe is corresponding on the position of aperture and the pallet, promptly aperture be in the ferrule openings end directly over.
Described pallet is for setting the PVC disk that several specify the aperture circular hole that has of unified size and specification; The chassis is the PVC disk with the same size of pallet, only offer on it with pallet on the locating hole corresponding positioning hole, do not offer the circular hole of mounting sleeve;
Alignment pin is the metallic rod that the lower end has the termination, its upper end has external screw thread, alignment pin is serially connected chassis, pallet and aperture adjustment pad successively, and be complementary cap nut and alignment pin of the external screw thread on the alignment pin is screwed, and then superimposed chassis and pallet are fixed as one; Male end in described alignment pin is arranged with the alignment pin fixed sleeving, and two ends of fixed sleeving are abutted against mutually with pallet and cap nut respectively, is used to cooperate alignment pin the fixing the multilayer pallet of designated length; The length of described alignment pin fixed sleeving determines that by the different length of sleeve pipe the length of alignment pin fixed sleeving is preferably identical with the length of sleeve pipe.
The little hole number that is in the proper top of a ferrule openings on the described aperture adjustment pad is 2-4, and evenly distributes in the vertical plane of sleeve pipe; Perhaps being in a ferrule openings, to rectify the little hole number of top be 1, and identical with internal diameter in sleeve pipe.
The present invention has following advantage:
1. make simply, draw materials easily.Can finish by hand fully when the present invention makes on a small quantity, then can get in touch, make in enormous quantities with plastic cement production firm as a large amount of making of need; In addition, the present invention draws materials easy especially, and pvc pipe material, sheet material are very easy to buy, and can choose different apertures pvc pipe according to the actual requirements, to realize the installation of centrifuge tubes with different diameters.
2. make things convenient for experimental work, owing to can select the centrifuge tube overcoat number of plies that stacks, so it is applicable to that diameter is identical, and highly different centrifuge tubes improves the instrument service efficiency greatly.As adopt the comparable first wife's centrifuge tube of this method gained centrifuge tube overcoat overcoat operating efficiency to improve more than the 300%-400%, be easy to simultaneously make and maintenance.
3. durable in use, easy to maintenance.Because the present invention makes simply, the low price of drawing materials is so needn't drop into too much manpower and materials as needing to change; It is also extremely convenient to change.
4. reasonable in design.Design of the present invention can make the user arbitrarily adjust the putting position of sample, determines the counterweight mode of pallet, and the free degree of use greatly promotes.
5. cost is low.The present invention is very easily to buy and cheap material is transformed the centrifuge tube outer tube, and fixation degree increases, and cost is extremely low.
