Abstract

The utility model relates to a rapid grinding device which comprises a grinding board and a test tube frame (3), wherein the grinding board comprises a board body (1) and grinding heads (2); the plurality of grinding heads (2) are arranged on the board body (1); a plurality of through holes (4) are formed in the test tube frame (3); the through holes correspond to the grinding heads (2) on the board body (1) in both position and interval; and the grinding heads (2) can be inserted into the through holes (4). The rapid grinding device disclosed by the utility model is suitable for grinding plant samples in small quantities, and is capable of grinding several samples at one time, therefore, the problem that the existing laboratory only can grind one sample at one time is completely solved; and the rapid grinding device is simple in structure, and is applicable to the small laboratory.

Description

Quick lapping device
Technical field
The utility model belongs to the Bioexperiment instrument field, relates to a kind of quick lapping device.
Background technology
In plant experimental, often use plant leaf blade is ground, carry out next step extraction work.At present, lapping device commonly used is mortar, although mortar is divided into different models, mortar can only carry out the grinding work of a sample, and, because the volume of mortar is larger, when the sample size of grinding when needs is very little, with mortar a lot of inconvenience are arranged, it is too little especially to grind the rear blade surplus, be difficult to take out from mortar, a large amount of samples sticks on the mortar wall.Therefore, laboratory at present short-cut method commonly used is, a small amount of blade is put into little centrifuge tube, adds a certain amount of liquid nitrogen, smash to pieces with the rifle head, still, because the rifle head is not lapping device after all, therefore, although this kind method can keep more sample size, the effect of grinding is bad.And, once can only grind a sample, when running into grinding in enormous quantities, these two kinds of methods are all not competent.Therefore, need to invent a kind of quick lapping device for this kind problem.
Summary of the invention
The purpose of this utility model provides a kind of quick lapping device, solves the used lapping device inefficiency in present laboratory, the problem that once can only grind a sample.
The utility model is achieved through the following technical solutions: quick lapping device, and this device comprises abrasive sheet and rack for test tube, abrasive sheet comprises plate body and grinding head, and a plurality of grinding heads are housed on the plate body; Have a plurality of through holes on the rack for test tube, the position of through hole is all corresponding with the grinding head on the plate body with spacing, and grinding head can be inserted in the through hole.
Described grinding head and plate body are for being threaded.
There is the papillary projection described grinding head end.
Described through hole inboard is provided with rubber ring.
Adopt the good effect of technique scheme:
1, the utility model is applicable to grind plant sample in a small amount, and can once grind a plurality of samples, thoroughly solves the problem that a sample once can only be ground in present laboratory;
2, in addition, because the grinding head wearing and tearing are more serious, and the grinding head in this device is designed to change at any time, therefore, can greatly reduce experimental cost, the convenient use;
3, the utility model is simple in structure, is fit to small-size laboratory and is equipped with use.
Description of drawings
Fig. 1 is the structural representation of abrasive sheet in the utility model;
Fig. 2 is the top view of rack for test tube in the utility model.
Among the figure, 1 plate body, 2 grinding heads, 3 rack for test tubes, 4 through holes, 5 rubber rings.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is the structural representation of abrasive sheet in the utility model, Fig. 2 is the top view of rack for test tube in the utility model, in conjunction with Fig. 1, shown in Figure 2, quick lapping device, this device comprises abrasive sheet and rack for test tube 3, abrasive sheet comprises plate body 1 and grinding head 2, and a plurality of grinding heads 2 are housed on the plate body 1, and grinding head 2 is mainly used in the grinding to plant leaf blade.Have a plurality of through holes 4 on the rack for test tube 3, the position of through hole 4 is all corresponding with the grinding head 2 on the plate body 1 with spacing, and grinding head 2 can be inserted in the through hole 4.The effect of through hole 4 is to insert little centrifuge tube, and therefore, grinding head 2 can be inserted in the through hole 4, also just can the blade in the little centrifuge tube be ground.
Because the wearing and tearing of grinding head 2 are the most serious, can obtain at any time changing in order to make the grinding head 2 after the wearing and tearing, grinding head 2 and plate body 1 are designed to be threaded.Like this, when part grinding head 2 serious wear, only removable parts grinding head 2 gets final product, other can continue use, reduce experimental cost.
There is the papillary projection grinding head 2 ends, mainly are in order to strengthen frictional force, so that the blade grinding is more abundant, to make things convenient for the carrying out of subsequent extracted work.
Because dynamics is larger when grinding, centrifuge tube may shake, and therefore is provided with rubber ring 5 in through hole 4 inboards, tightly blocks centrifuge tube, prevents to rock.
During use, a small amount of blade is positioned over respectively in the centrifuge tube, centrifuge tube is inserted in the through hole 4 of rack for test tube 3 again, add an amount of liquid nitrogen, the experimenter is inserted into grinding head 2 correspondences in the centrifuge tube, and sample is smashed to pieces and ground.After complete, sample does not need to take out from centrifuge tube, can carry out next step experiment.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.
