Abstract

The utility model discloses a kind of mortar liquid nitrogen grinding base, including base body, base sucking disc, foam fixed border, the base sucking disc is rounded, the plate-like of intermediate recess, the base body is the square made by polyurethane, its bottom is inlayed with sucker to combine together, and a square aperture is arranged at top；The foam fixed border is made of highly foaming polyethylene, the square hole surrounding positioned at base body top, for fixing mortar.The utility model mortar liquid nitrogen grinding base, selected materials are low for cost, the material easily obtained；Inventive principle is simple, but very practical；Main function fixes mortar when being liquid nitrogen grinding, is not required to hand firmly by helping, laborsaving raising efficiency, and prevent long-time operation from freezing hand.

Description

A kind of mortar liquid nitrogen grinding base

Technical field

The utility model belongs to technical field of experiment equipment, more particularly to a kind of mortar liquid nitrogen grinding base.

Background technology

Need to add liquid nitrogen grinding-material in mortar in Biotechnology Experiment, it is hand steered in long-time process of lapping to occur Phenomenon that is weak, starting.

The immediate prior art of the invention is liquid nitrogen grinding instrument, such as 6870 freezings of SPEX companies of U.S. production Grinder, principle are that sample is loaded to closed grinding container, are immersed in liquid nitrogen, using electromagnetism as power, drive steel to hit sub- powder Breakdown mill, sample are in liquid nitrogen temperature all the time in process of lapping, and many samples become fragile due to low temperature, this causes some in room The sample for being difficult to grind under temperature, both need not be individually pre- sample and grinding container before grinding by hitting sub- effect grind into powder It is cold, while temperature is controlled also without supplement liquid nitrogen in process of lapping, and at low temperature, composition information in sample and Bioactivity is perfectly retained.

Its shortcoming is too high for Costco Wholesale, too high for the material cost of some simple milled processeds.Designing this patent is The base of mortar during one liquid nitrogen grinding, it is possible to facilitate the operation of process of lapping.

Utility model content

The technique effect of the utility model is achieved through the following technical solutions：

A kind of mortar liquid nitrogen grinding base, including base body, base sucking disc, foam fixed border, the base sucking disc Rounded, intermediate recess plate-like, the base body are the square made by polyurethane, its bottom is inlayed with sucker merges It is integrated, a square aperture is arranged at top；The foam fixed border is made of highly foaming polyethylene, on base body The square hole surrounding in portion, for fixing mortar.

Preferably, the sucker is manufactured using nitrile rubber.

Preferably, the foam fixed border has large, medium and small model, is applicable in different size of mortar.

Beneficial effect：

1st, selected materials are low for cost, the material easily obtained.

2nd, inventive principle is simple, but very practical.

3rd, mortar is fixed when main function is liquid nitrogen grinding, is not required to hand firmly by helping, laborsaving raising efficiency, and prevent Hand is frozen in long-time operation.

Embodiment

Technical solutions of the utility model are discussed in detail below in conjunction with the accompanying drawings.

As shown in figures 1-8, the present invention is a mortar firm banking, is made of three parts.

1. Part I is the sucker 3 of bottommost, rounded, intermediate recess plate-like.Sucker material uses nitrile rubber Manufacture, has larger breaking tenacity, can be fixed base on the table by pressing.

2. Part II is middle part base body 2, the square made by polyurethane (PU), its bottom and sucker 3 Inlay and combine together, a square aperture equilateral with it is arranged at top.

3. Part III is the foam square frame 1 made of highly foaming polyethylene, the square of middle part is put in In hole, for fixing mortar.There is large, medium and small model, be applicable in different size of mortar.

The base of mortar when this patent is a liquid nitrogen grinding, the operation of convenient experiment.

In use, fixing base on the table by pressing sucker, grinding body is fixed on foam square frame.

Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it can still modify the technical solution described in foregoing embodiments, or to which part technical characteristic Carry out equivalent substitution.Where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.

Claims

1. a kind of mortar liquid nitrogen grinding base, it is characterised in that described including base body, base sucking disc, foam fixed border Base sucking disc is rounded, the plate-like of intermediate recess, and the base body is the square made by polyurethane, its bottom and sucker Inlay and combine together, a square aperture is arranged at top；The foam fixed border is made of highly foaming polyethylene, the bottom of positioned at The square hole surrounding of seat body upper part, for fixing mortar.
