Description
Technical field
The present invention relates to a kind of lapping device, more particularly to a kind of lapping device for DNA molecular experiment, belongs to experiment
Room equipment technology field.
Background technology
The lapping device of DNA molecular experiment is widely used in scientific experimentation and research, is had in school and scientific research institutions
Using existing lapping device structure is varied, there is machine mill, hand lapping device, is saved although machine mill is convenient
Thing, but cost is higher for some small experiments；And original hand lapping device is simple in construction, function is single, Zhi Nengjin
The simple sample grinding of row, effect are undesirable.And in present experiment and scientific research, it is desirable to have a kind of grinding of DNA molecular experiment
Device, can effectively grinding test sample, while can also be more economical, reduce cost, now there is presently no this lapping device,
This is to need to solve the problems, such as now.
The content of the invention
The technical problem to be solved in the present invention is：A kind of lapping device for DNA molecular experiment is provided, it passes through setting
Grinding box and grinding rod, the sample that will be ground are positioned in grinding box, manually rotate grinding rod, you can sample is carried out
Grinding, the present apparatus is simple in construction, convenient and practical, solves above-mentioned technical problem.
The technical scheme is that：It is a kind of for DNA molecular experiment lapping device, it include grinding rod, handle and
Grinding box, the grinding box are a cylindrical cavity structure, and its bottom is hemisphere closed, and upper end is open, grinding rod
It is vertically placed in grinding box, the grinding rod is up big and down small cone structure, and lower end is spherical grinding head, and upper end is hemisphere
There is a vertical bolt hole shape, centre, handle are connected with the bolt hole.
The handle is a metal bar, is fixedly connected by three sections, the vertical shape of epimere, is lever piece, and interlude is horizontal,
The vertical shape of hypomere, it is linkage section, has external screw thread on linkage section, be cased with locking nut thereon.
Taper knob is arranged with the lever piece of the handle.
The taper knob is double-decker, and internal layer is sponge material, and outer layer is elastomeric material.
The grinding rod and grinding box are plastic material.
The outside diameter of the grinding rod is smaller 1~2mm than the interior diameter of grinding box.
The beneficial effects of the invention are as follows：Compared with prior art, simple and reasonable, convenient and practical, grinding head of the invention
Small spheroidal is designed as, contacts with sample more abundant in the process of lapping made, improves the effect of grinding；Ground relative to machine
For device, this grinding rod is more economically economical, and cost is low, meanwhile, if in the case where machine mill is broken, grinding rod
It can immediately use, not influence experiment progress；Handle causes bent, can be more laborsaving in process of lapping, and makes to grind
Mill is more abundant；Taper knob is arranged with the lever piece of handle；Testing crew is enabled to be ground work for a long time, and
Will not opponent damage（Get blister, gall skin etc.）；The big end of grinding head is designed as point more a little bit smaller than the mouth of pipe of grinding box,
The mouth of pipe of grinding box can be blocked in process of lapping, prevents sample（Insect head, chest, leg etc. extract DNA material）Fly out, this dress
Put simple in construction, convenient and practical, the effect that operates is preferable.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below with reference to this specification accompanying drawing to this hair
It is bright to be described in further detail.
Embodiment 1：As shown in Figure 1, a kind of lapping device for DNA molecular experiment, it includes grinding rod 2, handle 3
With grinding box 1, the grinding box 1 is a cylindrical cavity structure, and its bottom is hemisphere closed, and upper end is opening, is ground
Frotton 2 is vertically placed in grinding box 1, and the grinding rod 2 is up big and down small cone structure, and lower end is spherical grinding first 7, on
Hold has a vertical bolt hole 6, handle 3 is connected with the bolt hole 6 for semi-spherical shape, centre.Grinding head 7 is designed as roundlet
It is spherical, more abundant, raising grinding effect is contacted in the process of lapping made with sample；For machine mill, this
Grinding rod 2 is more economically economical, and cost is low；Meanwhile if in the case where machine mill is broken, grinding rod can make immediately
With not influenceing experiment progress.
Further, handle 3 is a metal bar, is fixedly connected by three sections, the vertical shape of epimere, is lever piece, interlude
It is horizontal, the vertical shape of hypomere, it is linkage section, has external screw thread on linkage section, be cased with locking nut 5 thereon.Bent is now transformed into,
Can be more laborsaving in process of lapping, and make grinding more abundant.
For convenience of dismounting and change, locking nut 5 is set on the linkage section of handle, handle 3 is broken changeable grip 3, grinding
Rod 2 is broken replaceable grinding rod 2, more economical material benefit, durable.
Further, taper knob 4 is arranged with the lever piece of handle 3 so that testing crew can be ground for a long time
Grinder is made, and is damaged without opponent（Get blister, gall skin etc.）.
Further, taper knob 4 is double-decker, and internal layer is sponge material, and outer layer is elastomeric material.
Further, grinding rod 2 and grinding box 1 are plastic material.
Further, the outside diameter of grinding rod 2 is smaller 1~2mm than the interior diameter of grinding box 1.The big end design of grinding head
For point more a little bit smaller than the mouth of pipe of grinding box, the mouth of pipe of grinding box can be blocked in process of lapping, prevents sample（Insect head, chest,
Leg etc. extracts DNA material）Fly out, improve grinding effect, ensure that the reliability of experiment.
Part is not described in detail by the present invention, is the known technology of those skilled in the art of the present technique.Finally illustrate, the above is real
Example is applied to be merely illustrative of the technical solution of the present invention and unrestricted, although having been carried out specifically to the present invention with reference to preferred embodiment
